Description
본 발명은 교류전원의 위상각 제어 통신을 이용한 기기 제어 장치 및 방법에 관한 것으로, 보다 상세하게는 유선 또는 무선 통신망을 통해 전송되거나 직접 입력된 제어대상 기기의 동작모드 데이터를 기기에 공급되는 교류전원의 위상각 제어를 이용해 단방향으로 전송하여 기기를 제어하는 장치 및 방법에 관한 것이다.The present invention relates to a device control apparatus and method using phase angle control communication of an AC power source, and more particularly, an AC power supply for supplying operation mode data of a control target device transmitted through a wired or wireless communication network or directly to a device. The present invention relates to an apparatus and a method for controlling a device by transmitting in one direction by using phase angle control of a.
본 발명의 배경이 되는 기술은 대한민국 등록특허 제10-1313002호에 개시되어 있는 바와 같이, 교류전원의 위상각을 조절한 파형과 조절하지 않은 파형이 조합된 순열을 발생하여 직렬 데이터를 전송하는 데이터 통신방법에 관한 것이다.As the background technology of the present invention, as disclosed in Korean Patent No. 10-1313002, data for transmitting serial data by generating a permutation of a waveform in which a phase angle of an AC power source is adjusted and a waveform that is not controlled are generated. It relates to a communication method.
일반적으로 통신을 이용하여 원격으로 기기를 제어하기 위해서는 유무선 통신망을 이용하거나 교류선로상에 아날로그 통신신호를 중첩시켜 데이터를 전송하는 전력선 통신을 이용하는 것이 일반적이다.In general, in order to control a device remotely using communication, it is common to use a wired / wireless communication network or power line communication that transmits data by superimposing analog communication signals on an AC line.
유선을 이용할 경우 별도의 통신선을 가설하기 위한 비용이 증가하고, 무선을 이용할 경우 설치는 간편하지만 유선에 비해 상대적으로 고가인 통신장치를 이용하여야 하며 혼선에 의한 데이터 유실의 가능성이 있다는 문제점이 있다.In case of using a wire, the cost for laying a separate communication line increases, and in the case of using a wire, the installation is simple, but a relatively expensive communication device is required compared to the wire, and there is a possibility of data loss due to crosstalk.
또한 전력선 통신의 경우 별도의 통신망 없이 전원 공급선을 이용하여 통신이 가능하지만 기타 전기기기에 의한 외란에 취약한 특성이 있어 일반적으로 사용되기 어렵다는 문제점이 있다.In addition, in the case of power line communication, communication is possible using a power supply line without a separate communication network, but there is a problem in that it is generally difficult to use because it is vulnerable to disturbance caused by other electric devices.
종래의 전력선통신은 결합회로, 주파수변환회로, SS확산, PN부호, 제어회로, 전원회로를 포함한다.Conventional power line communication includes a coupling circuit, a frequency conversion circuit, an SS spread, a PN code, a control circuit, and a power supply circuit.
무선통신에서 널리 사용되는 확산스펙트럼(Spread spectrum)방식을 사용한 전력선 통신의 경우 반송주파수대역의 노이즈를 발생하는 전력기기가 선로상에 존재할 경우 통신이 불가능하므로 전력망 구성에 제약이 많아지는 문제점이 있다.In the case of power line communication using a spread spectrum method widely used in wireless communication, there is a problem in that a power network configuration becomes more limited because communication is impossible when a power device generating noise of a carrier frequency band exists on a line.
교류전원을 이용하는 전열기, 조명기기 등의 출력량을 사용환경에 맞게 조절하여 전력을 절감하기 위해 일반적으로 SCR(Silicon controlled rectifier), 트랜지스터(Transistor)등을 이용해 공급되는 전력의 위상각을 제어하거나 트랜스(Transformer)를 이용해 전압을 제어하여 공급되는 실효전력량 (RMS Power)을 조절하는 방법을 사용한다. 전압이나 위상각을 제어하여 공급되는 실효전력량을 조절하는 방식의 전력 절감기의 경우 공급전력의 전압이 낮아지거나 전력이 공급되지 않는 구간이 존재함으로 인해 부하기기의 특성에 따라 부하기기가 이상동작 할 수 있는 문제점이 있다.In order to save power by adjusting the output of heaters and lighting equipment using AC power according to the usage environment, the phase angle of the power supplied using SCR (Silicon controlled rectifier), transistor, etc. is generally controlled. It uses a method of controlling the RMS power supplied by controlling the voltage using a transformer. In the case of a power saver that controls the amount of effective power supplied by controlling the voltage or phase angle, the load may be abnormally operated depending on the characteristics of the load device because the voltage of the supply power is lowered or there is a section in which no power is supplied. There is a problem.

도 1을 참조하면, 교류전원은 일반적으로 60Hz또는 50Hz의 주기로 1/2주기마다 반대극성을 갖는 사인함수형태의 전력이 공급되는 특성을 갖는다.Referring to FIG. 1, an AC power source generally has a characteristic of supplying power having a sinusoidal function having an opposite polarity every 1/2 cycle with a period of 60 Hz or 50 Hz.
교류전원의 위상각을 제어하는 방법으로는 0도, 180도에서 존재하는 영전압점을 기준으로 파형의 시작부분의 위상을 제어하는 리딩에지 제어(leading edge cutting) 방식과 파형의 끝부분의 위상을 제어하는 트레일링에지 제어(trailing edge)방식이 있다. 이때, 위상각을 제어하는 방법에 있어서 리딩에지 제어방식 또는 트레일링에지 제어방식만을 사용하거나 리딩에지 제어방식과 트레일링에지 제어방식을 조합하여 사용할 수도 있다.As a method of controlling the phase angle of AC power, the leading edge cutting method which controls the phase of the beginning of the waveform based on the zero voltage point existing at 0 degree and 180 degrees, and the phase of the end of the waveform There is a trailing edge control method. In this case, in the method of controlling the phase angle, only the leading edge control method or the trailing edge control method may be used, or the leading edge control method and the trailing edge control method may be used in combination.
*본 발명의 기기 제어장치의 일 실시예에서는 시스템제어기(200)에서 리딩에지를 조절한 파형과 트레일링에지를 조절한 파형, 위상각을 조절하지 않은 파형을 조합하여 순차적으로 통신수신기(300)에 공급함으로써 제3제어부(410)에 수신 데이터패킷을 전송한다.In one embodiment of the device control apparatus of the present invention, the system receiver 200 sequentially combines the waveforms of the leading edges, the trailing edges, and the phase angles of the communication receivers 300. The received data packet is transmitted to the third controller 410 by supplying to the third controller 410.
혹은, 본 발명의 기기 제어 장치는 영전압점의 인근, 혹은 영전압점에서 기설정된 범위의 영역에 대하여 스위칭부를 통하여 교류전원을 ON 혹은 OFF 제어, 혹은 스케줄링된 ON 혹은 OFF제어를 함으로써 데이터패킷을 전송할 수 있다. 여기서 스케줄링된 ON 혹은 OFF 제어는 상기 영전압점에서 기설정된 범위의 영역에서 2 이상의 ON, OFF를 스케줄링된 타임에 따라 제어하는 것이다.Alternatively, the device control apparatus of the present invention can transmit the data packet by performing ON or OFF control of the AC power, or scheduled ON or OFF control through the switching unit in the vicinity of the zero voltage point or in the region of the preset range at the zero voltage point. have. Here, the scheduled ON or OFF control is to control two or more ON and OFF in the region of the predetermined range at the zero voltage point according to the scheduled time.

The non-corrugated waveforms may be sequentially supplied to correspond to the complement of the binary values of the waveform whose phase angle is adjusted, thereby serially transmitting the received data packet to the third controller 410.
이와 같은 대응관계는 실시예에 따라 변경될 수 있다.Such a correspondence may be changed according to an embodiment.

도 2를 참조하면, 본 발명의 기기 제어 장치는 시스템제어기(200), 통신수신기(300), 기기제어기(400), 컨트롤패널(600)을 포함한다.Referring to FIG. 2, the device control apparatus of the present invention includes a system controller 200, a communication receiver 300, a device controller 400, and a control panel 600.
시스템제어기(200)는 통신부(210), 전원부(220), 제1영전압검출부(230), 스위칭부(240), 제1제어부(250), 및 전력량검출부(260)를 포함한다.The system controller 200 includes a communication unit 210, a power supply unit 220, a first zero voltage detection unit 230, a switching unit 240, a first control unit 250, and a power amount detection unit 260.
전원부(220)는 교류전원(20)을 정류하여 제1제어부(250)와 통신부(210)에 필요한 전력을 공급한다.The power supply unit 220 rectifies the AC power supply 20 to supply power required for the first control unit 250 and the communication unit 210.
통신부(210)는 유무선 통신망(30)을 통해서 외부 단말로부터 기기들의 제어와 관련이 있는 송신대상 데이터패킷(10)을 수신하여 제1제어부(250)로 출력한다. 이때, 데이터패킷(10)은 개시비트, 이진수 1 또는 이진수 0이거나, 혹은 개시비트, 이진수 1 또는 이진수 0으로 변환될 수 있다.The communication unit 210 receives a transmission target data packet 10 related to control of devices from an external terminal through the wired / wireless communication network 30 and outputs the received data packet 10 to the first control unit 250. In this case, the data packet 10 may be a start bit, binary 1 or binary 0, or may be converted into a start bit, binary 1 or binary 0.
*제1영전압검출부(230)는 교류전원의 전압이 영전압이 되는 시점인 제1영전압점을 검출하여 제1영전압점신호를 제1제어부(250)로 출력한다.The first zero voltage detector 230 detects the first zero voltage point at which the voltage of the AC power becomes zero and outputs the first zero voltage point signal to the first controller 250.
제1제어부(250)는 제1영전압검출부(230)로부터 제1영전압점신호를 수신하고 통신부(210)를 통해 데이터패킷을 수신하여 제1영전압점에 데이터패킷에 상응하는 신호로 변환하기 위하여 스위칭부(240)를 제어한다.The first controller 250 receives the first zero voltage point signal from the first zero voltage detector 230, receives the data packet through the communication unit 210, and converts the signal into a signal corresponding to the data packet at the first zero voltage point. The switching unit 240 is controlled.
이 때, 본 발명의 일 실시예에 따르면 제1제어부(250)에는 오프 상태에서 온 상태로 변환되는 제1스위칭신호, 온 상태가 지속되는 제2스위칭신호, 온 상태에서 오프 상태로 변환되는 제3스위칭신호가 미리 저장된다. 이와 같은 스위칭신호는 실시예에 따라 변할 수 있다.At this time, according to an embodiment of the present invention, the first control unit 250 includes a first switching signal that is switched from an off state to an on state, a second switching signal that remains on, and a first state that is switched from an on state to an off state. 3 The switching signal is stored in advance. Such a switching signal may vary depending on the embodiment.
제1영전압검출부(230)로부터 제1영전압점을 파악하고, 통신 개시시 제1영전압점이 검출되면 개시 비트에 매칭된 스위칭신호를 스위칭부(240)에 인가하고, 그 다음 제1영전압점이 검출될 때마다 송신대상 데이터패킷을 이루는 비트값에 매칭된 해당 스위칭신호를 순차적으로 스위칭부(240)에 인가한다.The first zero voltage point is detected from the first zero voltage detector 230, and when the first zero point is detected at the start of communication, a switching signal matched to the start bit is applied to the switching unit 240, and then the first zero voltage point is applied. Each time a point is detected, the corresponding switching signal matched to the bit value constituting the data packet to be transmitted is sequentially applied to the switching unit 240.
이 때, 개시 비트에는 제1스위칭신호 또는 제3스위칭신호가 매칭되고, 이진수 1비트 및 이진수 0비트에는 개시 비트에 매칭된 스위칭신호를 제외한 나머지 2개의 스위칭신호가 각각 임의적으로 매칭된다. 이와 같은 스위칭신호는 실시예에 따라 변할 수 있다.In this case, the first switching signal or the third switching signal is matched to the start bit, and the other two switching signals except the switching signal matched to the start bit are arbitrarily matched to the binary 1 bit and the binary 0 bit, respectively. Such a switching signal may vary depending on the embodiment.
즉, 제1제어부(250)는 상기 제1영전압점신호가 입력될 때마다 데이터패킷에 따라 대응되는 제1스위칭신호, 제2스위칭신호 또는 제3스위칭신호를 스위칭부(240)에 출력한다.That is, each time the first zero voltage point signal is input, the first controller 250 outputs a first switching signal, a second switching signal, or a third switching signal corresponding to the data packet to the switching unit 240.
제1제어부(250)는 통신부(210)를 통해 외부 단말로부터 수신된 데이터패킷(10)을 판독한다. 판독한 데이터가 기기 제어 신호일 경우 이에 해당하는 스위칭신호를 생성하여 스위칭부로 출력한다.The first controller 250 reads the data packet 10 received from the external terminal through the communication unit 210. If the read data is a device control signal, a corresponding switching signal is generated and output to the switching unit.
스위칭부(240)는 교류전원(20)을 입력 받고, 상기 제1제어부(250)로부터 제1스위칭신호 내지 제3스위칭신호를 인가 받아 상기 제1스위칭신호 내지 제3스위칭신호가 온 상태일 경우에는 상기 교류전원(20)을 통과시키고, 오프 상태일 경우에는 상기 교류전원(20)을 차단시켜 생성된 변형 교류전원을 출력한다.When the switching unit 240 receives the AC power source 20 and receives the first switching signal to the third switching signal from the first control unit 250, the switching unit 240 is in the on state. The alternating current power source 20 passes through the alternating current power source 20 and, in the off state, cuts off the alternating current power source 20 to output the generated alternating current power source.
이 때, 스위칭부(240)는 FET, Transistor, IGBT등의 반도체 스위칭 소자로 구현될 수 있다.At this time, the switching unit 240 may be implemented as a semiconductor switching device such as FET, Transistor, IGBT.
전력량검출부(260)는 상기 교류전원(20)의 전력량을 검출하여 제1제어부(250)로 출력한다. 상기 전력량검출부(260)에서 검출된 전력량의 변화를 통해, 연결된 기기의 동작 상태를 모니터링 하여 동작모드를 식별하고, 동작의 이상 여부를 검토할 수 있다. 이와 같은 동작모드식별방법과 이상여부판별방법에 대해서는 후술하기로 한다.The power amount detector 260 detects the power amount of the AC power source 20 and outputs the power amount to the first controller 250. Through the change in the amount of power detected by the power amount detection unit 260, it is possible to monitor the operation state of the connected device to identify the operation mode, and examine whether the operation is abnormal. The operation mode identification method and the error determination method will be described later.
도 2를 참조하면 상기 전력량검출부(260)는 스위칭부(240)를 통과한 변형 교류전원의 전력량을 검출하나, 본 발명은 이에 한정되지 않는다. 상기 전력량검출부(250)는 도 2에 도시된 바와 같이, 스위칭부(240)를 통과한 변형 교류전원의 전력량을 검출하는 방식으로 동작할 수도 있고, 혹은 스위칭부(240)를 통과하기 전의 교류전원(20)의 전력량을 검출하는 방식으로 동작할 수도 있다.Referring to FIG. 2, the power amount detection unit 260 detects the power amount of the modified AC power that has passed through the switching unit 240, but the present invention is not limited thereto. As shown in FIG. 2, the power amount detection unit 250 may operate in a manner of detecting a power amount of the modified AC power that has passed through the switching unit 240, or AC power before passing through the switching unit 240. It may also operate in a manner of detecting the amount of power (20).
기기제어기(400)는 통신수신기(300) 및 제3제어부(410)를 포함한다. 이와 같은 기기제어기는 기기와 인접하게 배치됨이 바람직하다.The device controller 400 includes a communication receiver 300 and a third controller 410. Such a device controller is preferably arranged adjacent to the device.

본 발명은 위상각제어 통신신호의 분석이 불가능한 재래식 전원공급기를 제어하기 위해 통신수신기(300)를 사용한다.The present invention uses a communication receiver 300 to control a conventional power supply that is impossible to analyze the phase angle control communication signal.
제2영전압검출부(330)는 스위칭부(240)에서 출력된 변형 교류전원을 수신하여 변형 교류전원의 전압이 영전압이 되는 시점인 제2영전압점을 검출하여 제2영전압점신호를 제2제어부(320)로 출력한다.The second zero voltage detector 330 receives the modified AC power output from the switching unit 240, detects a second zero voltage point at which the voltage of the modified AC power becomes a zero voltage, and generates a second zero voltage point signal. Output to the control unit 320.
제2제어부(320)는 상기 제2영전압점신호를 순차적으로 수신하고, 변형 교류전원의 제2영전압점이 검출될 때 마다 그 시점을 기준으로 반주기 동안의 제2영전압점신호가 온 상태에서 오프 상태를 유지하는 경우, 오프 상태를 지속적으로 유지하는 경우, 오프 상태에서 온 상태를 유지하는 경우 중 어느 경우에 해당하는지 판단한다.The second controller 320 sequentially receives the second zero voltage point signal, and when the second zero voltage point of the modified AC power source is detected, the second zero voltage point signal for half a cycle is turned off in the on state based on the time point. In the case of maintaining the state, the case in which the case of maintaining the off state in the off state is determined.
이에 따라 제2영전압점신호가 오프 상태에서 온 상태를 유지하는 경우에는 상기 제3스위칭신호에 미리 매칭된 비트값으로 판독하고, 오프상태를 지속적으로 유지하는 경우는 제2스위칭신호에 미리 매칭된 비트값으로 판독하고, 온 상태에서 오프 상태를 유지하는 경우는 제1스위칭신호에 미리 매칭된 비트값으로 판독하여, 각 판독된 비트값을 순차적으로 취합한 수신 데이터패킷을 출력한다. 이때, 제2제어부(320)는 생성된 상기 수신 데이터패킷을 저장할 수 있다.Accordingly, when the second zero voltage point signal is maintained in the off state, the second zero voltage point signal is read with a bit value previously matched to the third switching signal, and when the second zero voltage point signal is continuously maintained, the second zero voltage point signal is previously matched to the second switching signal. In the case of reading the bit value and maintaining the off state in the on state, the read data packet is read out using the bit value matched with the first switching signal in advance, and the received data packet is collected by sequentially collecting the read bit values. In this case, the second controller 320 may store the generated received data packet.

To this end, the second controller 320 stores the unique identification information and outputs a received data packet only when the stored unique identification information and the unique identification information of the received data packet match or the device 500 according to the received data packet. Outputs a control signal.

이하, 본 발명인 교류전원의 위상각 제어 통신을 이용한 기기 제어 장치 및 방법의 실시예 동작에 대하여 상세히 설명한다.Hereinafter, the operation of the embodiment of the device control apparatus and method using the phase angle control communication of the present invention AC power will be described in detail.
먼저, 시스템제어기(200)가 외부로부터 이진수 1비트 및 이진수 0비트로 이루어진 기기모드제어값을 나타내는 송신대상 데이터패킷(10) 및 교류전원(20)을 수신한다.First, the system controller 200 receives a transmission target data packet 10 and an AC power source 20 representing a device mode control value consisting of a binary 1 bit and a binary 0 bit from the outside.

Each of the start bit, the binary 1 bit, and the binary 0 bit may be arbitrarily matched and stored, and the first zero voltage point is detected by the first zero voltage detector 230. When the first zero voltage point is detected at the start of communication, the start bit is detected. Is applied to the switching unit 240, and each time the first zero voltage point is detected, the corresponding switching signal matched to the bit value constituting the data packet to be transmitted is sequentially applied to the switching unit 240. do.
그 다음, 시스템제어기(200) 내 스위칭부(240)가 상기 교류전원(20)을 입력 받고, 상기 제1제어부(250)로부터 제1스위칭신호 내지 제3스위칭신호를 인가 받아 상기 제1스위칭신호 내지 제3스위칭신호가 온 상태일 경우에는 상기 교류전원(20)을 통과시키고, 오프 상태일 경우에는 상기 교류전원(20)을 차단시켜 생성된 변형 교류전원을 출력한다.Next, the switching unit 240 in the system controller 200 receives the AC power supply 20, receives the first switching signal to the third switching signal from the first control unit 250, and the first switching signal. When the third switching signal is in the on state, the AC power source 20 is passed through, and in the off state, the AC power source 20 is cut off to generate a modified AC power source.
그 다음, 통신수신기(300) 내 제2영전압검출부(330)가 상기 스위칭부(240)로부터 출력된 변형 교류전원을 수신하여 제2영전압점을 순차적으로 검출하여 제2제어부(320)에 전송한다.Next, the second zero voltage detector 330 in the communication receiver 300 receives the modified AC power output from the switching unit 240, sequentially detects the second zero voltage point, and transmits the same to the second controller 320. do.
그 다음, 통신수신기(300) 내 제2제어부(320)가 상기 제2영전압점을 순차적으로 수신하고, 상기 제2영전압점이 검출될 때마다 그 시점을 기준으로 반주기 동안의 제2영전압점신호가 오프 상태에서 온 상태를 유지하는 경우는 상기 제3스위칭신호에 미리 매칭된 비트값으로 판독하고, 오프 상태를 지속적으로 유지하는 경우는 제2스위칭신호에 미리 매칭된 비트값으로 판독하고, 온 상태에서 오프 상태를 유지하는 경우는 제1스위칭신호에 미리 매칭된 비트값으로 판독하여, 각 판독된 비트값을 순차적으로 취합한 수신 데이터패킷을 출력한다.Next, the second control unit 320 in the communication receiver 300 sequentially receives the second zero voltage point, and whenever the second zero voltage point is detected, the second zero voltage point signal during the half cycle based on the time point. Maintains the on state in the off state, reads the bit value previously matched to the third switching signal; if maintains the off state continuously, reads the bit value previously matched to the second switching signal, the on state In the case of maintaining the OFF state in the state, a read data packet is read out with a bit value previously matched to the first switching signal, and a received data packet obtained by sequentially collecting the read bit values is output.
이때, 제2제어부(320)는 제2영전압점이 검출될 때마다 그 시점을 기준으로 반주기 동안의 제2영전압점신호를 판단하되, 상기 제2영전압점신호가 개시비트에 해당하는 신호인 경우, 그 시점부터 수신 데이터패킷을 생성한다.In this case, whenever the second zero voltage point is detected, the second controller 320 determines the second zero voltage point signal for a half cycle based on the time point, and when the second zero voltage point signal corresponds to a start bit. From that point on, create a receive data packet.
그 다음, 통신수신기 내 저장부에 수신 데이터패킷을 저장한다.The received data packet is then stored in a storage in the communication receiver.
이 때, 통신수신기는 수신 데이터패킷을 저장하지 않을 수도 있다.At this time, the communication receiver may not store the received data packet.
그 다음, 제3제어부(410)가 상기 제2제어부(320)로부터 수신 데이터패킷을 수신하여, 상기 수신 데이터패킷에 해당하는 기기모드제어값을 기반으로 연결된 기기(500)의 동작모드를 제어한다.Next, the third controller 410 receives the received data packet from the second controller 320 and controls the operation mode of the connected device 500 based on the device mode control value corresponding to the received data packet. .
본 발명은 상기 과정을 통해 데이터를 수신하여 기기(500)의 동작모드를 제어한다.The present invention controls the operation mode of the device 500 by receiving data through the above process.

패널입력부(610)는 외부로부터 시스템 제어명령을 입력 받아 시스템제어기(200) 내 제1제어부(250)로 상기 시스템 제어명령을 전달한다. 상기 제1제어부(250)는 상기 패널입력부(610)를 통해 입력된 신호를 판독하여 이에 해당하는 스위칭신호를 생성하여 스위칭부(240)로 출력한다.The panel input unit 610 receives a system control command from the outside and transmits the system control command to the first control unit 250 in the system controller 200. The first controller 250 reads a signal input through the panel input unit 610, generates a corresponding switching signal, and outputs the corresponding switching signal to the switching unit 240.

도 4는 본 발명의 일 실시예에 따른 교류전원의 위상각 제어 통신을 이용한 기기 제어 장치 및 방법의 시스템제어기 회로도이다.4 is a system controller circuit diagram of a device control apparatus and method using phase angle control communication of an AC power source according to an embodiment of the present invention.
먼저, 제1영전압검출부(230)에 관하여 설명한다.First, the first zero voltage detector 230 will be described.
일반적인 교류전원(20)은 50 또는 60 Hz의 주기로 전압의 크기와 방향이 변한다. 인가되는 교류전원(20)은 저항 분배회로(R1, R2, R3)를 통해 회로에서 인식 가능한 전압으로 떨어진다. 시간에 따라 변화하는 전압에 의해 브리지회로(D1, D2, D3, D4)의 부에 연결된 Capacitor(C1)가 충전되고 전압이 낮아지면 D5를 통해 방전된다. C1에 충전된 전압에 의해 포토 커플러(OP2)가 동작하게 되고 영전압점신호입력으로 절연된 Low신호가 입력된다. 교류 전원(20)의 전압이 주기에 따라 크기가 0전압에 도달하면 C1이 방전되어 포토 커플러(OP2)의 동작이 중단되고 영전압점신호 입력단자에 절연된 High신호가 입력된다. 교류전원(20)은 한 주기에 0전압이 두 번 발생하므로 영전압점신호는 교류전원(20) 주파수의 2배의 주기로 발생한다.The general AC power supply 20 changes in magnitude and direction of voltage at a period of 50 or 60 Hz. The applied AC power supply 20 drops to a voltage recognizable by the circuit through the resistor distribution circuits R1, R2, and R3. The capacitor C1 connected to the portions of the bridge circuits D1, D2, D3, and D4 is charged by the voltage that changes with time, and is discharged through D5 when the voltage is lowered. The photo coupler OP2 is operated by the voltage charged in C1, and the low signal insulated by the zero voltage point signal input is input. When the voltage of the AC power source 20 reaches 0 voltage according to the cycle, C1 is discharged to stop the operation of the photo coupler OP2 and the high signal insulated to the zero voltage point signal input terminal is input. Since the zero voltage point signal is generated twice in one cycle, the zero voltage point signal is generated at twice the frequency of the alternating current power source 20 frequency.
이와 같은 영전압 검출부의 회로 원리는 통상적으로 사용되는 것이므로 이에 관한 더 이상의 자세한 설명은 생략한다.Since the circuit principle of the zero voltage detection unit is commonly used, a detailed description thereof will be omitted.
스위칭부(240)는, 제1 FET(Q1), 제2 FET(Q2), 포토 커플러(OP1), 제너 다이오드 및 콘덴서를 포함한다.The switching unit 240 includes a first FET Q1, a second FET Q2, a photo coupler OP1, a zener diode, and a capacitor.
제1 FET(Q1)은 N채널 트랜지스터로서 드레인단은 상기 교류전원과 전기적으로 연결되고, 소스단은 제1 접지단과 전기적으로 연결되고, 게이트단은 제1 노드에 전기적으로 연결된다.The first FET Q1 is an N-channel transistor. The drain terminal is electrically connected to the AC power source, the source terminal is electrically connected to the first ground terminal, and the gate terminal is electrically connected to the first node.
제2 FET(Q2)은 N채널 트랜지스터로서 소스단은 상기 제1 접지단과 전기적으로 연결되고, 게이트단은 상기 제1 노드에 전기적으로 연결되며, 드레인단으로 변형 교류전원이 출력된다.The second FET Q2 is an N-channel transistor, a source terminal of which is electrically connected to the first ground terminal, a gate terminal of which is electrically connected to the first node, and a modified AC power source is output to a drain terminal.
포토 커플러(OP1)은, 제1단은 제1 직류전원(Vcc)에 연결된 제1 저항에 전기적으로 연결되고, 제2단은 상기 제1제어부의 스위칭신호 출력단과 전기적으로 연결되고, 제3단은 제2 직류전원(Vdd)에 연결된 제2 저항과 전기적으로 연결되고, 제4단은 제2 접지단과 전기적으로 연결되어, 제1단에서 제2단으로 전류가 흐르면 제3단에서 제4단으로 전류가 도통된다.The photo coupler OP1 has a first stage electrically connected to a first resistor connected to a first DC power supply Vcc, a second stage electrically connected to a switching signal output terminal of the first control unit, and a third stage. Is electrically connected to a second resistor connected to a second DC power supply (Vdd), and the fourth stage is electrically connected to the second ground terminal, and when current flows from the first stage to the second stage, the third stage to the fourth stage Current is conducted.
제너 다이오드는 상기 제1 노드와 제2 접지단 사이에 전기적으로 연결된다.The zener diode is electrically connected between the first node and the second ground terminal.
콘덴서도 상기 제1 노드와 제2 접지단 사이에 전기적으로 연결된다.A capacitor is also electrically connected between the first node and the second ground terminal.
또한, 제1제어부(250)의 스위칭신호 출력단에서 출력되는 제1 내지 제3 스위칭 신호는, 온 상태의 전압 크기는 상기 제1 직류전원(Vcc)의 크기(예컨대, 3.3V)와 동일하게 하며, 제1 내지 제3 스위칭 신호의 오프 상태 전압 크기는 Low 전압으로서 거의 0 V에 가까울 것이다.In addition, the first to third switching signals output from the switching signal output terminal of the first control unit 250, the voltage level of the on state is the same as the magnitude (for example 3.3V) of the first DC power supply (Vcc). The off-state voltage magnitude of the first to third switching signals will be nearly 0 volts as a low voltage.
즉, 제1제어부(250)의 스위칭신호 출력단에 걸리는 전압이 제1 직류전원인 Vcc 전압과 동일하다면, 포토 커플러의 제1단과 제2단의 전압차가 없어 전류가 흐르지 않게 되고, 따라서, 포토 커플러의 제3단과 제4단 사이에도 전류가 흐르지 않게 되어 제1 노드에는 제2 직류전원(Vdd)이 일정한 비율로 분배된 전압이 걸리게 된다. 따라서, 이 경우 제1 노드에 걸리는 전압은 제1 접지단의 전압보다 높은 전압이 걸리게 되어 제1 FET는 드레인에서 소스방향으로 전류가 흐르게 되고, 제2 FET는 소스에서 드레인 방향으로 전류가 흐르게 되어, 결국 입력되는 교류전원이 제2 FET의 드레인단으로 그대로 통과하게 된다.That is, if the voltage applied to the switching signal output terminal of the first control unit 250 is the same as the Vcc voltage of the first DC power supply, there is no voltage difference between the first end and the second end of the photocoupler, and thus no current flows. Since no current flows between the third and fourth stages of the second node, the first node receives a voltage at which the second DC power supply Vdd is divided at a constant rate. Therefore, in this case, the voltage applied to the first node is higher than the voltage of the first ground terminal so that current flows from the drain to the source direction, and the second FET flows from the source to the drain direction. As a result, the input AC power passes through the drain terminal of the second FET as it is.
제1제어부의 스위칭신호 출력단에 걸리는 전압이 상술한 Low 전압이라면, 포토 커플러의 제1단과 제2단 사이에 전압차가 생겨 전류가 흐르게 되고, 따라서 포토 커플러의 제3단과 제4단 사이에도 전류가 흐르게 되어 제3단의 전압은 제2 접지단의 전압 크기로 떨어질 것이고, 이에 따라 제1 노드의 전압 역시 제2 접지단과 비슷한 크기의 전압으로 떨어지게 된다. 따라서, 이 경우 제1 노드에 걸리는 전압은 제1 접지단의 전압 크기와 동일하게 되며, 이에 따라 제1 FET 및 제2 FET의 게이트단에 걸리는 제1 노드 전압이 제1 접지단과 동일하게 되므로 제1 FET 및 제2 FET 모두 전류가 흐르지 않게 되어, 결국 입력되는 교류전원이 차단된다.If the voltage applied to the switching signal output terminal of the first control unit is the low voltage described above, a voltage difference is generated between the first and second ends of the photocoupler, so that current flows. As a result, the voltage of the third terminal drops to the magnitude of the voltage of the second ground terminal, and thus the voltage of the first node also falls to a voltage similar to that of the second ground terminal. Therefore, in this case, the voltage applied to the first node is equal to the voltage of the first ground terminal, and thus the first node voltage applied to the gate terminals of the first FET and the second FET is equal to the first ground terminal. In both the first FET and the second FET, no current flows, and eventually the AC power input is interrupted.
위상각제어는 제1영전압점신호를 기준으로 동작하게 되고, 위상각을 제어하지 않는 주기에는 제1영전압점신호를 기준으로 다음 제1영전압점신호 입력까지 위상각 제어회로를 ON상태로 유지한다.Phase angle control operates on the basis of the first zero voltage point signal, and maintains the phase angle control circuit in the ON state until the next input of the zero voltage point signal on the basis of the first zero voltage point signal in a period where the phase angle is not controlled. .
리딩에지를 제어하는 주기에는 영전압점신호를 기준으로 위상각 제어시간 동안 위상각 제어회로를 OFF상태로 유지한 후 다음 영전압점신호가 입력될 때까지 위상각 제어회로를 ON상태로 유지한다.In the period of controlling the leading edge, the phase angle control circuit is kept OFF for the phase angle control time based on the zero voltage point signal, and the phase angle control circuit is kept ON until the next zero voltage point signal is input.
트레일링에지를 제어하는 경우 영전압점신호를 기준으로 트레일링에지 제어 지연시간 동안 위상각 제어회로를 ON으로 제어한 후 위상각 제어시간 동안 위상각 제어회로를 OFF로 유지한다.When the trailing edge is controlled, the phase angle control circuit is controlled to ON during the trailing edge control delay time based on the zero voltage point signal, and then the phase angle control circuit is maintained to OFF during the phase angle control time.
본 발명은 리딩에지 제어파형, 트레일링에지 제어파형, 위상각을 제어하지 않은 파형 등 3가지의 조합이 발생하므로 이진데이터에 대응하여 데이터를 표현하기 위한 경우 외에 데이터의 시작점을 표시할 수 있다. 개시비트에 의한 개시신호를 이용하여 데이터의 시작점을 표시함으로써, 데이터 통신이 원활하게 동작할 수 있도록 구성된 일반적인 시리얼 통신을 구현하기 용이하다.According to the present invention, three combinations of a leading edge control waveform, a trailing edge control waveform, and a waveform having no phase angle control are generated. Therefore, the starting point of the data can be displayed in addition to the case of representing the data in response to the binary data. By indicating the start point of the data by using the start signal by the start bit, it is easy to implement general serial communication configured to facilitate data communication.
도 5는 본 발명의 일 실시예에 따른 교류전원의 위상각 제어 통신을 이용한 기기 제어 장치 및 방법의 시스템제어기를 통해 검출된 파형을 보여주는 도면이고, 도 6은 본 발명의 일 실시예에 따른 교류전원의 위상각 제어 통신을 이용한 기기 제어 장치 및 방법의 통신수신기에서 판독된 파형을 보여주는 도면이다.FIG. 5 is a view showing waveforms detected by a system controller of an apparatus and apparatus for controlling a device using phase angle control communication of an AC power source according to an embodiment of the present invention, and FIG. 6 is an alternating current according to an embodiment of the present invention. A diagram showing waveforms read by a communication receiver of a device control apparatus and method using phase angle control communication of a power supply.
도 5 및 도 6을 참조하면, 먼저 제1제어부(250)는 제1스위칭신호 내지 제3스위칭신호가 저장되고, 상기 제1스위칭신호 내지 제3스위칭신호는 교류전원에 통신부를 통해 입력된 데이터인 개시비트, 이진수1 또는 0을 입혀 개시비트, 이진수1 또는 0에 대응되는 각 스위칭신호로, 입력된 상기 데이터에 따라 대응되는 스위칭신호가 스위칭부에 인가된다.Referring to FIGS. 5 and 6, first, the first control unit 250 stores the first switching signal to the third switching signal, and the first switching signal to the third switching signal are data inputted through the communication unit to an AC power source. In each switching signal corresponding to the start bit, binary 1 or 0 by applying the start bit, binary 1 or 0, the corresponding switching signal is applied to the switching unit according to the input data.
제1스위칭신호는 오프 상태이다가 온 상태로 변환되는 신호이고, 제2스위칭신호는 지속적으로 온 상태로 유지되는 신호이고, 제3스위칭신호는 온 상태에서 오프 상태로 변환되는 신호이다.The first switching signal is a signal that is turned off and then turned to an on state, the second switching signal is a signal that is continuously kept in an on state, and the third switching signal is a signal that is turned from an on state to an off state.
이때, 제1스위칭신호는 교류전원의 제1영전압점을 기준으로 시작부분의 위상을 절단하여 절단된 구간 동안만 스위칭신호가 오프 상태이고 절단되지 않은 부분부터 다시 온 상태가 되는 것으로, 리딩에지 제어파형이다.In this case, the first switching signal is a state in which the switching signal is turned off only during the cut section by cutting the phase of the start portion based on the first zero voltage point of the AC power, and is turned on again from the uncut section. Waveform.
제2스위칭신호는 교류전원의 제1영전압점을 기준으로 위상의 변화가 없어 스위칭신호가 지속적으로 온 상태이다.Since the second switching signal has no phase change with respect to the first zero voltage point of the AC power source, the switching signal is continuously turned on.
제3스위칭신호는 교류전원의 제1영전압점을 기준으로 끝부분의 위상을 절단하여 절단된 구간 동안만 스위칭신호가 오프 상태이므로, 제1영전압점에서 절단된 구간 이전까지는 온 상태이다가 절단된 구간에서 오프 상태가 되는 것으로, 트레일링에지 제어파형이다.Since the switching signal is turned off only during the section cut by cutting the phase of the end of the third switching signal based on the first zero voltage point of the AC power source, the third switching signal is turned on until the section cut from the first zero voltage point. It is turned off in the section, and it is a trailing edge control waveform.
본 발명은 이와 같은 방법으로 기기의 동작모드를 제어한다.The present invention controls the operation mode of the device in this way.
시스템제어기(200)에 교류전원(20)이 입력되면 제1제어부(250)에 제1영전압검출부(230)에 의해 검출된 상기 교류전원의 제1영전압점이 입력된다.When the AC power source 20 is input to the system controller 200, the first zero voltage point of the AC power source detected by the first zero voltage detector 230 is input to the first controller 250.
이때, 제1제어부(250)에는 오프 상태에서 온 상태로 전환되는 제1스위칭신호, 온 상태로 유지되는 제2스위칭신호 및 온 상태에서 오프 상태로 전환되는 제3스위칭신호가 저장되고, 제1스위칭신호, 제2스위칭신호, 제3스위칭신호 각각은 개시비트 또는 이진수 1 또는 이진수 0과 각각 매칭되도록 설정된다.In this case, the first control unit 250 stores a first switching signal switched from the off state to the on state, a second switching signal maintained from the on state, and a third switching signal switched from the on state to the off state. Each of the switching signal, the second switching signal, and the third switching signal is set to match the start bit or binary 1 or binary 0, respectively.
예를 들어, 이진수 1에는 제1스위칭신호가 매칭되고, 이진수 0에는 제2스위칭신호가 매칭되고, 개시비트에는 제3스위칭신호가 매칭된다고 가정했을 경우, 제1제어부(250)는 통신부에 이진수 1이 입력되면 상기 이진수 1에 대응되는 제1스위칭신호를 스위칭부(240)에 출력한다.For example, assuming that the first switching signal is matched to binary 1, the second switching signal is matched to binary 0, and the third switching signal is matched to start bit, the first controller 250 is binary to the communication unit. When 1 is input, the first switching signal corresponding to the binary number 1 is output to the switching unit 240.
스위칭부(240)는 제1스위칭신호에 따라 오프 상태인 구간에서는 교류전원을 차단시키고, 온 상태인 구간에서는 교류전원을 통과시키고, 교류전원에 이진수 1을 입혀 생성된 변형 교류전원을 통신수신기(300)로 출력한다.The switching unit 240 cuts off the AC power in the OFF state according to the first switching signal, passes the AC power in the ON state, and transmits the alternating AC power generated by applying binary 1 to the AC power. 300).
통신수신기(300) 내 제2영전압검출부(330)는 변형 교류전원의 제2영전압점을 검출하고, 제2영전압점 신호를 제2제어부(320)에 전송한다.The second zero voltage detector 330 in the communication receiver 300 detects the second zero voltage point of the modified AC power and transmits the second zero voltage point signal to the second controller 320.
이때, 제2제어부(320)에는 제2영전압점을 기준으로 판단해야 할 반주기가 미리 지정된다.In this case, the second controller 320 is previously designated a half cycle to be determined based on the second zero voltage point.
예를 들어, 제2제어부(320)에 변형 교류전원의 반주기를 기준으로 판단하도록 지정된 경우, 제2제어부(320)는 변형 교류전원이 입력되면 제2영전압점을 검출하여 제2영전압점을 기준으로 반주기가 끝나는 시점에 판단한다.For example, when the second controller 320 is specified to be determined based on a half cycle of the modified AC power, the second controller 320 detects the second zero voltage point based on the second zero voltage point when the modified AC power is input. It is judged at the end of the half cycle.
즉, 제2제어부(320)는 변형 교류전원이 입력되고 제2영전압점신호가 검출될 때마다 온오프 상태를 판독하고, 반주기가 끝나는 시점의 온오프 상태를 판독하여 온 상태에서 오프 상태로 또는 오프에서 온 상태로 또는 오프 상태로 유지되었는지를 감지하여 그에 따라 각각의 수신 데이터패킷을 도출한다.That is, the second controller 320 reads the on-off state every time the modified AC power is input and the second zero voltage point signal is detected, and reads the on-off state at the end of the half cycle to turn the on-off state or It detects whether it remains off or on off and derives each received data packet accordingly.
또한, 제2제어부(320)는 변형 교류전원의 제2영전압점을 기준으로 개시비트와 매칭된 스위칭신호가 입력된 경우에만 동작한다. 이는 노이즈로 인한 불필요한 동작 발생을 방지하기 위함이다.In addition, the second controller 320 operates only when a switching signal matching the start bit is input based on the second zero voltage point of the modified AC power source. This is to prevent unnecessary operation caused by noise.
예를 들어, 변형 교류전원은 제2영전압점을 기준으로 제2영전압점 신호가 오프 상태이다가 온 상태가 되는 경우, 오프 상태에서 온 상태로 전환되는 시점이 데이터 개시점이다.For example, in the modified AC power source, when the second zero voltage point signal is turned on from the off state based on the second zero voltage point, the modified AC power source is the data start point.

이하, 시스템제어기(200)에 교류전원(20)이 입력되고 외부 단말로부터 데이터패킷 10100101이 입력되고, 제1제어부(250)에는 제1스위칭신호 또는 제3스위칭신호는 이진수 1과 매칭되고, 제2스위칭신호는 이진수 0과 매칭되도록 설정되고, 제2제어부에는 제2영전압점을 기준으로 반주기 구간을 판독하도록 설정된 경우를 예로 설명한다.Hereinafter, the AC controller 20 is input to the system controller 200, the data packet 10100101 is input from an external terminal, and the first switching signal or the third switching signal is matched with binary 1 to the first controller 250. The second switching signal is set to match the binary zero, and the second controller is set to read a half cycle period based on the second zero voltage point as an example.
도 7을 참조하면, 제2제어부(320)에 개시비트(S)를 시작으로 인지하고, 여기서 개시비트는 제2영전압점을 기준으로 반주기 동안의 제2영전압점신호가 온 상태에서 오프 상태로 전환되거나 제2영전압점신호가 오프 상태에서 온 상태로 전환되는 스위칭신호와 매칭된다. 즉, 개시비트는 트레일링에지 제어파형 또는 리딩에지 제어파형과 대응된다.Referring to FIG. 7, the second control unit 320 recognizes the start bit S as a start, wherein the start bit is changed from the on state to the off state during the half period based on the second zero voltage point. Or the second zero voltage point signal is matched with a switching signal that is switched from an off state to an on state. That is, the start bit corresponds to the trailing edge control waveform or the leading edge control waveform.
그 다음, 제2영전압점을 기준으로 반주기 동안의 제2영전압점신호가 오프 상태에서 온 상태로 전환되는 경우로, 제1스위칭신호와 매칭된 비트값 이진수 1이 검출된다.Then, in the case where the second zero voltage point signal during the half cycle based on the second zero voltage point is switched from the off state to the on state, the bit value binary 1 matched with the first switching signal is detected.
그 다음, 제2영전압점을 기준으로 반주기 동안의 제2영전압점신호가 오프 상태로 유지되는 경우로, 제2스위칭신호와 매칭된 비트값 이진수 0이 검출된다.Then, in the case where the second zero voltage point signal during the half cycle with respect to the second zero voltage point is kept off, the bit value binary 0 matched with the second switching signal is detected.
그 다음, 제2영전압점을 기준으로 반주기 동안의 제2영전압점신호가 오프 상태에서 온 상태로 전환되는 경우로, 제1스위칭신호와 매칭된 비트값 이진수 1이 검출된다.Then, in the case where the second zero voltage point signal during the half cycle based on the second zero voltage point is switched from the off state to the on state, the bit value binary 1 matched with the first switching signal is detected.
그 다음, 제2영전압점을 기준으로 반주기 동안의 제2영전압점신호가 오프 상태로 유지되는 경우로, 제2스위칭신호와 매칭된 비트값 이진수 0이 검출된다. 그 다음 이진수 0 또한 같은 과정으로 인한 비트값이다.Then, in the case where the second zero voltage point signal during the half cycle with respect to the second zero voltage point is kept off, the bit value binary 0 matched with the second switching signal is detected. Then binary 0 is also the bit value from the same process.
그 다음, 제2영전압점을 기준으로 반주기 동안의 제2영전압점신호가 온 상태에서 오프 상태로 전환되는 경우로, 제3스위칭신호와 매칭된 비트값 이진수 1이 검출된다.Then, in the case where the second zero voltage point signal during the half cycle based on the second zero voltage point is switched from the on state to the off state, the bit value binary 1 matching the third switching signal is detected.
그 다음, 제2영전압점을 기준으로 반주기 동안의 제2영전압점신호가 오프 상태로 유지되는 경우로, 제2스위칭신호와 매칭된 비트값 이진수 0이 검출된다.Then, in the case where the second zero voltage point signal during the half cycle with respect to the second zero voltage point is kept off, the bit value binary 0 matched with the second switching signal is detected.
그 다음, 제2영전압점을 기준으로 반주기 동안의 제2영전압점신호가 온 상태에서 오프 상태로 전환되는 경우로, 제3스위칭신호와 매칭된 비트값 이진수 1이 검출된다.Then, in the case where the second zero voltage point signal during the half cycle based on the second zero voltage point is switched from the on state to the off state, the bit value binary 1 matching the third switching signal is detected.
이와 같이 이진수 1은 제1스위칭신호 또는 제3스위칭신호와 매칭된 비트값으로, 제2영전압점을 기준으로 반주기 동안의 제2영전압점신호가 온 상태에서 오프 상태로 전환되거나 오프 상태에서 온 상태로 전환되는 경우에 출력된다. 이진수 0은 제2스위칭신호와 매칭되어 제2영전압점을 기준으로 반주기 동안의 제2영전압점신호가 오프 상태로 유지되는 경우에 출력된다.As described above, the binary number 1 is a bit value matched with the first switching signal or the third switching signal, and the second zero voltage point signal for half a period from the on state to the off state or the on state from the off state based on the second zero voltage point. It is output when switched to. The binary zero is matched with the second switching signal and is output when the second zero voltage point signal is kept off for half a period based on the second zero voltage point.
즉, 개시비트는 리딩에지 제어파형 또는 트레일링에지 제어파형에 대응되고, 전송하고자 하는 데이터는 이진수로 변환되어 나머지 위상각 제어파형을 이진수 1 또는 이진수 0에 대응되도록 하고, 위상각을 조절하지 않은 파형은 위상각을 조절한 파형의 이진수(10100101) 값의 보수(01011010)에 대응되도록 하여 순차적으로 공급함으로써, 제3제어부(410)에 수신 데이터패킷을 직렬 전송한다.That is, the start bit corresponds to the leading edge or trailing edge control waveform, and the data to be transmitted is converted into binary so that the remaining phase angle control waveform corresponds to binary 1 or binary 0, and the phase angle is not adjusted. The waveforms are sequentially supplied to correspond to the complementary number (01011010) of the binary number 10100101 value of the waveform whose phase angle is adjusted, thereby serially transmitting the received data packet to the third controller 410.
제3제어부(410)는 제2제어부(320)에서 판독된 수신 데이터패킷 10100101을 수신하여 상기 수신 데이터패킷에 해당하는 기기모드제어값을 기반으로 연결된 기기(500)의 동작모드를 제어한다. 예를 들어, 상기 기기모드제어값이 동작모드 2의 실행이라고 가정하면 수신 데이터패킷 10100101에 해당하는 동작모드 2를 작동시키는 신호를 기기로 전송하는 것이다.The third controller 410 receives the received data packet 10100101 read by the second controller 320 and controls the operation mode of the connected device 500 based on the device mode control value corresponding to the received data packet. For example, assuming that the device mode control value is the execution of the operation mode 2, a signal for operating the operation mode 2 corresponding to the received data packet 10100101 is transmitted to the device.

그 다음, 모드학습부(254)는 스위칭신호제어부(251)로 모드 m-n을 종료하도록 하는 기기모드제어값을 전송하여, 기기 m이 모드 n을 종료하도록 한다(S24).Next, the mode learning unit 254 transmits the device mode control value for terminating the mode m-n to the switching signal controller 251, so that the device m ends the mode n (S24).
그 다음, 모드학습부(254)는 모드데이터저장부(252)에 모드 m-n에 대하여 S22에서 계산한 전력량을 저장하도록 한다(S30).Next, the mode learning unit 254 stores the amount of power calculated in S22 for the mode m-n in the mode data storage unit 252 (S30).
그 다음, 모드학습부(254)는 내부의 카운터 n을 1 증가시킨다(S40).Next, the mode learning unit 254 increments the counter n by one (S40).
그 다음, 모드학습부(254)는 내부의 카운터 n이 nm을 초과하는지 검사한다(S50). 이 때, nm은 모드학습부(254)에 기저장된 수로, 기기 m이 동작할 수 있는 동작모드의 개수이다.Next, the mode learning unit 254 checks whether the internal counter n exceeds n m (S50). In this case, n m is a number previously stored in the mode learning unit 254, and is the number of operation modes in which the device m may operate.
만약 카운터 n이 nm을 초과하지 않는다면, 다시 S21단계로 돌아가 증가한 n에 대한 전력량변화 계산 및 저장단계를 반복한다.If the counter n does not exceed n m , go back to step S21 and repeat the step of calculating and storing the change in power for n.
만약 카운터 n이 nm을 초과한다면, 모드학습부(254)는 내부의 카운터 m을 1 증가시키고, n은 다시 1로 설정한다(S60).If the counter n exceeds n m , the mode learning unit 254 increments the internal counter m by 1, and sets n to 1 again (S60).
그 다음, 모드학습부(254)는 내부의 카운터 m이 ms를 초과하는지 검사한다(S70). 이 때, ms는 모드학습부(254)에 기저장된 수로, 시스템에 연결된 기기의 개수이다.Next, the mode learning unit 254 checks whether the internal counter m exceeds m s (S70). At this time, m s is a number pre-stored in the mode learning unit 254 and is the number of devices connected to the system.
만약 카운터 m이 ms를 초과하지 않는다면, 다시 S21단계로 돌아가 증가한 m에 대한 전력량변화 계산 및 저장단계를 반복한다.If the counter m does not exceed m s , go back to step S21 and repeat the step of calculating and storing the power change for m.
만약 카운터 m이 ms를 초과한다면, 모드학습부(254)는 동작을 종료한다.If the counter m exceeds m s , the mode learning unit 254 ends the operation.
이와 같은 과정을 통해서 모드학습부(254)는 시스템에 연결된 모든 기기의 모든 동작모드에 대해 실행 및 종료를 반복하면서 각 동작모드에 대한 전력량변화를 모드데이터저장부(252)에 저장할 수 있게 된다.Through this process, the mode learning unit 254 may store the power amount change for each operation mode in the mode data storage unit 252 while repeating execution and termination for all operation modes of all devices connected to the system.
본 발명의 일 실시예에 따르면 바람직하게는, 상기 S21단계 내지 S24단계에 대해, 기설정된 횟수만큼 반복 실행하여 얻어진 전력량변화 계산값 데이터의 대표값을 해당 동작모드의 전력량으로 설정하여 모드데이터저장부(252)에 저장하도록 할 수 있다. 이와 같은 반복 실행을 통하여, 보다 정확한 전력량 데이터를 구축할 수 있게 되는 효과를 발휘할 수 있다.According to an embodiment of the present invention, preferably, in step S21 to S24, a mode data storage unit by setting the representative value of the power change calculation value data obtained by repeatedly executing a predetermined number of times as the power amount of the operation mode; 252 may be stored. Through such repetitive execution, it is possible to exert an effect that more accurate power amount data can be constructed.
도 10의 (B)는 모드학습방법의 또 다른 실시예를 도시한다.10 (B) shows another embodiment of the mode learning method.
먼저 전력량검출부(260)는 현재의 전력량을 검출한다(S110).First, the power amount detection unit 260 detects the current power amount (S110).
그 다음, 모드학습부(254)는 입력부(257)로부터 통신부(210) 또는 패널입력부(610)를 통해 입력된 데이터패킷(10)의 기기모드제어값에 기초한 모드 m-n의 실행 명령을 수신한다(S120).Then, the mode learning unit 254 receives an execution command of the mode mn based on the device mode control value of the data packet 10 input through the communication unit 210 or the panel input unit 610 from the input unit 257 ( S120).
그 다음, 스위칭신호제어부(251)는 스위칭신호를 생성하고, 스위칭부(240)는 상기 스위칭신호에 따라 변형 교류전원을 생성하고, 상기 변형 교류전원을 수신한 기기제어기(400)에 의해 모드 m-n이 실행된다(S130).Next, the switching signal controller 251 generates a switching signal, and the switching unit 240 generates a modified AC power according to the switching signal, and receives the mode mn by the device controller 400 receiving the modified AC power. This is executed (S130).
그 다음, 전력량변화계산부(253)는 S110단계에서 검출한 전력량 및 S130단계 이후에 검출한 전력량을 비교하여 전력량변화를 계산한다(S140).Next, the power amount change calculation unit 253 calculates the power amount change by comparing the power amount detected in step S110 with the power amount detected after step S130 (S140).
그 다음, 모드학습부(254)는 모드데이터저장부(252)에 모드 m-n에 대하여 S140에서 계산한 전력량을 저장하도록 하고(S150) 동작을 종료한다.Next, the mode learning unit 254 stores the amount of power calculated in S140 for the mode m-n in the mode data storage unit 252 (S150) and ends the operation.
이와 같은 본 발명의 일 실시예에 따르면, 입력된 데이터패킷(10)의 기기모드제어값에 의해 제어를 수행할 때 마다 전력량 데이터를 학습하도록 하여 모드데이터저장부(252)의 데이터를 갱신할 수 있게 된다.According to one embodiment of the present invention, the data of the mode data storage unit 252 can be updated by learning power amount data every time control is performed by the input device mode control value of the data packet 10. Will be.
도 11은 본 발명의 일 실시예에 따른 교류전원의 위상각 제어 통신을 이용한 기기 제어 장치 및 방법의 모드식별방법에 따른 내부 구성들의 동작을 개략적으로 도시하는 도면이다.FIG. 11 is a view schematically showing the operation of internal components according to the mode identification method of the device control apparatus and method using the phase angle control communication of the AC power according to an embodiment of the present invention.
모드식별부(255)는 시스템에 연결된 기기의 동작모드를 식별하기 위하여, 모드데이터저장부(252)에 저장된 동작모드에 대한 전력량 데이터 및 전력량변화계산부(253)가 도출한 전력량변화에 기초하여 현재의 동작모드를 파악한다.The mode identifying unit 255 may identify the operation mode of the device connected to the system, based on the power amount data for the operation mode stored in the mode data storage unit 252 and the change in power amount derived by the power amount change calculation unit 253. Know the current mode of operation.
이를 위해 상기 모드식별부(255)는 상기 전력량변화계산부(253)가 도출한 전력량변화가 0이 아닐 때마다, 전력량변화계산부(253)로부터 전력량변화를 수신하여, 상기 전력량변화값과 모드데이터저장부(252)에 저장된 동작모드에 대한 전력량 데이터를 비교하여, 동작모드의 변화를 파악하고, 이를 저장한다.To this end, the mode identification unit 255 receives a change in power amount from the change amount calculation unit 253 whenever the change in amount of power derived by the change amount calculation unit 253 is not 0, and thus the change amount value and the mode. By comparing the amount of power data for the operation mode stored in the data storage unit 252, the change of the operation mode is grasped and stored.
이 후, 모드식별부(255)는 식별한 동작모드의 변화를 출력부(258)를 통해 시스템제어기(200)의 통신부(210) 및/또는 컨트롤패널(600)의 표시부(620)로 전송한다. 상기 통신부(210)는 수신한 동작모드의 변화를 외부통신망(30)을 통해 외부의 관리기기로 전송하고, 상기 표시부(620)는 수신한 동작모드의 변화를 장치에 출력한다.Thereafter, the mode identification unit 255 transmits the identified change of the operation mode to the communication unit 210 of the system controller 200 and / or the display unit 620 of the control panel 600 through the output unit 258. . The communication unit 210 transmits the received change of the operation mode to the external management device through the external communication network 30, and the display unit 620 outputs the received change of the operation mode to the device.
이와 같이 전력량변화계산부(253)가 도출한 전력량변화가 0이 아닐 때마다, 즉 전력량이 변할 때 마다 동작모드를 식별함으로써, 시스템제어기(200)에 의해 기기가 제어되는 경우 외에, 사용자에 의해 기기가 직접 제어되고 모드가 변경되는 경우에도 이에 따른 동작모드의 변화를 식별할 수 있고, 식별된 상기 동작모드를 출력부(258)를 통해 통신부(210) 또는 표시부(620)로 전송함으로써, 시스템제어기(200)의 관리자가 동작모드를 확인할 수 있게 된다. 즉, 모드식별부(255)의 동작을 통해, 단방향으로만 데이터를 전송할 수 있는 교류전원의 위상각 제어 통신 하에서 연결된 기기(500)의 동작 상태를 피드백 받을 수 있는 효과를 발휘할 수 있다.As described above, the operation mode is identified whenever the change in power amount calculated by the power change calculation unit 253 is not zero, i.e., whenever the amount of power changes, so that the device is controlled by the system controller 200. Even when the device is directly controlled and the mode is changed, it is possible to identify a change in the operation mode accordingly, and by transmitting the identified operation mode to the communication unit 210 or the display unit 620 through the output unit 258, The administrator of the controller 200 can check the operation mode. That is, through the operation of the mode identification unit 255, it is possible to achieve the effect of receiving the feedback of the operating state of the connected device 500 under the phase angle control communication of the AC power that can transmit data only in one direction.
도 12 및 도 13은 본 발명의 일 실시예에 따른 교류전원의 위상각 제어 통신을 이용한 기기 제어 장치 및 방법의 모드식별방법을 개략적으로 도시하는 도면이다.12 and 13 are diagrams schematically illustrating a mode identification method of a device control apparatus and method using phase angle control communication of an AC power source according to an embodiment of the present invention.
도 12 및 도 13에는 모드데이터저장부(252)에 저장된 동작모드 별 전력량 데이터 및 전력량변화계산부(253)가 도출한 전력량변화가 도시되어 있다. 상기 모드데이터저장부(252)에는 사용자가 직접 입력한 동작모드 별 전력량 데이터 또는 모드학습부의 동작에 따라서 입력된 동작모드 별 전력량 데이터가 저장되어 있다.12 and 13 illustrate power amount data for each operation mode stored in the mode data storage unit 252 and power amount change derived by the power amount change calculator 253. The mode data storage unit 252 stores power amount data for each operation mode directly input by the user or power amount data for each operation mode according to the operation of the mode learning unit.
전력량변화계산부(253)는 전력량검출부(260)가 검출한 전력량의 시간에 따른 전력량변화값을 도출한다. 도출된 상기 전력량변화값은 모드식별부(255)로 전송된다.The power amount change calculation unit 253 derives a power amount change value with time of the power amount detected by the power amount detection unit 260. The derived change amount of power is transmitted to the mode identification unit 255.
모드식별부(255)는 전력량변화계산부(253)로부터 수신한 전력량변화값을 상기 모드데이터저장부(252)의 전력량 데이터와 비교하여 이와 동일 또는 오차범위 내의 값을 찾고, 이에 해당하는 동작모드를 추출한다.The mode identification unit 255 compares the power amount change value received from the power amount change calculation unit 253 with the power amount data of the mode data storage unit 252 and finds a value within the same or an error range, and the operation mode corresponding thereto. Extract
도 12에 도시된 실시예에 따르면, 전력량변화계산부(253)가 도출한 전력량변화값은 +44kW이고, 이를 모드데이터저장부(252)에 저장된 전력량 데이터와 비교하면, 상기 전력량변화값과 오차범위 내의 모드 2-1을 추출할 수 있고, 시스템의 두번째 기기가 첫번째 동작모드를 개시하게 되었음을 알 수 있다. 즉, 상기 모드식별부(255)는 모드데이터저장부(252)에 저장된 전력량데이터에 기설정된 규칙에 따라 오차범위를 부여할 수 있다.According to the embodiment shown in FIG. 12, the power amount change value derived by the power amount change calculation unit 253 is +44 kW, and when compared with the power amount data stored in the mode data storage unit 252, the power amount change value and the error are determined. It is possible to extract mode 2-1 in range, indicating that the second device in the system has initiated the first mode of operation. That is, the mode identification unit 255 may assign an error range to the power amount data stored in the mode data storage unit 252 according to a predetermined rule.
만약 전력량변화값이 -44kW였다면, 동작모드의 개시가 아닌, 동작모드의 종료로 판단할 수 있다.If the change in power amount is -44 kW, it may be determined that the operation mode is terminated, not the start of the operation mode.
이 후, 상기 모드식별부(255)는 식별한 동작모드의 변화를 출력부(258)를 통해 통신부(210) 및 표시부(620)로 전송할 수 있다.Thereafter, the mode identification unit 255 may transmit the change of the identified operation mode to the communication unit 210 and the display unit 620 through the output unit 258.
도 13에 도시된 실시예에 따르면, 전력량변화계산부(253)가 도출한 전력량변화값은 +92kW이고, 이를 모드데이터저장부(252)에 저장된 전력량 데이터와 비교하면, 상기 전력량변화값과 오차범위 내의 모드 1-3 및 모드 2-2를 추출할 수 있다. 이와 같이 두 개 이상의 동작모드의 전력량 데이터가 동일하거나 유사한 경우, 전력량변화값만으로는 동작모드를 식별할 수 없게 된다.According to the embodiment shown in FIG. 13, the power amount change value derived by the power amount change calculation unit 253 is +92 kW, and when compared with the power amount data stored in the mode data storage unit 252, the power amount change value and the error are determined. Mode 1-3 and mode 2-2 within the range can be extracted. As such, when the amount of power data of two or more operation modes are the same or similar, the operation mode cannot be identified only by the change in the amount of power.
이런 경우, 모드식별부(255)는 시스템에 연결된 기기(500)의 동작모드를 제어하는 방식으로 동작모드를 식별할 수 있다.In this case, the mode identification unit 255 may identify the operation mode by controlling the operation mode of the device 500 connected to the system.
모드식별부(255)는 전력량변화값만으로 동작모드를 식별할 수 없는 경우, 시스템에 연결된 모든 기기의 모든 동작모드에 대해 동작 개시 후 종료명령을 전송하는 테스트를 수행하고, 상기 테스트 동안 검출된 전력량변화 정보를 모드데이터저장부(252)에 저장된 전력량 데이터와 비교하여, 데이터와 일치하지 않는 동작모드를 검출한다.If the mode identification unit 255 cannot identify the operation mode based only on the change in power amount, the mode identification unit 255 performs a test for transmitting an end command after starting operation for all operation modes of all devices connected to the system, and detects the amount of power during the test. The change information is compared with the amount of power data stored in the mode data storage unit 252 to detect an operation mode that does not match the data.
도 13과 같은 실시예에 있어서 실제 시스템의 동작모드가 2-2인 경우, 모드식별부(255)가 모드 1-3의 동작 개시 후 종료명령을 전송하면, 모드데이터저장부(252)에 저장된 전력량 데이터와 동일하게 전력량이 90kW 증가하였다가 다시 90kW 감소하게 된다. 이에 반해 모드식별부(255)가 모드 2-2의 동작 개시 후 종료명령을 전송하면, 이미 모드 2-2는 동작 중이었기 때문에 전력량의 증가 없이 90kW만 감소하게 된다. 이 때, 모드식별부(255)는 동작모드를 모드 2-2로 식별하고, 다시 모드 2-2의 동작 개시명령을 내려서 종료된 모드 2-2를 다시 동작하게 한다.13, when the operation mode of the actual system is 2-2, when the mode identification unit 255 transmits an end command after the operation of the mode 1-3 starts, it is stored in the mode data storage unit 252. As with the power amount data, the power amount increases by 90 kW and then decreases by 90 kW. On the contrary, when the mode identification unit 255 transmits a termination command after the operation of the mode 2-2 starts, the mode 2-2 is already in operation, and thus only 90 kW is reduced without increasing the amount of power. At this time, the mode identification unit 255 identifies the operation mode as the mode 2-2, and gives the operation start command of the mode 2-2 again to operate the terminated mode 2-2 again.
바람직하게는, 모드식별부(255)가 모든 기기의 모든 동작모드에 대해 테스트를 수행하지 않고 전력량변화계산부(253)가 계산한 전력량변화값과 동일 또는 오차범위 내의 값에 해당하는 모드데이터저장부(252)에 저장된 전력량 데이터의 동작모드에 대해서만 테스트를 수행하여, 테스트의 소요시간을 줄이고, 불필요한 동작모드의 수행을 방지한다.Preferably, the mode identification unit 255 stores the mode data corresponding to a value within the error range or equal to the power change value calculated by the power change calculation unit 253 without performing a test on all operation modes of all devices. The test is performed only on the operation mode of the power amount data stored in the unit 252 to reduce the time required for the test and to prevent unnecessary operation mode.
혹은, 시스템에 연결된 기기의 동작모드가 다른 동작모드와 배타적으로 동작하는 경우, 예를 들면 모드 1-2를 동작하면 모드 1-1 및 모드 1-3이 종료되는 것과 같은 경우, 각 기기에 대해 하나씩의 모드만을 테스트 해 봄으로써, 동작 중이었던 기기를 파악하고, 이를 통하여 동작모드를 식별할 수도 있다.Alternatively, if the operation mode of the device connected to the system operates exclusively with other operation modes, for example, when Mode 1-2 operates, Mode 1-1 and Mode 1-3 terminate, By testing only one mode, you can identify the device that was running and identify the operating mode.
도 13과 같은 실시예에 있어서 실제 시스템의 동작모드가 2-2인 경우, 모드식별부(2550)가 모드 1-1의 동작 개시 후 종료명령을 전송하면, 모드데이터저장부(252)에 저장된 전력량 데이터와 동일하게 전력량이 30kW 증가하였다가 다시 30kW 감소하게 된다. 이에 반해 모드식별부(255)가 모드 2-1의 동작 개시 후 종료명령을 전송하면, 이미 모드 2-2가 동작 중이었기 때문에 모드 2-1이 동작 개시함과 동시에 모드 2-2는 종료되고, 이에 따라 전력량이 45kW 감소하고 모드 2-1이 종료됨에 따라 다시 45kW 감소하게 된다. 이 때, 모드식별부(255)는 동작모드를 모드 2-2로 식별하고, 다시 모드 2-2의 동작 개시명령을 내려서 종료된 모드 2-2를 다시 동작하게 한다.13, when the operation mode of the actual system is 2-2, when the mode identification unit 2550 transmits an end command after the operation of the mode 1-1 starts, the mode data storage unit 252 stores the mode data storage unit 252. As with the power amount data, the power amount increases by 30 kW and then decreases by 30 kW. On the contrary, if the mode identification unit 255 transmits a termination command after the operation of the mode 2-1 starts, the mode 2-1 starts and the mode 2-2 ends at the same time because the mode 2-2 has already been operated. As a result, the amount of power is reduced by 45 kW and as the mode 2-1 ends, the power is reduced by 45 kW. At this time, the mode identification unit 255 identifies the operation mode as the mode 2-2, and gives the operation start command of the mode 2-2 again to operate the terminated mode 2-2 again.
이와 같이 시스템의 동작모드를 식별한 후, 상기 모드식별부(255)는 식별한 동작모드의 변화를 출력부(258)를 통해 통신부(210) 및 표시부(620)로 전송할 수 있다.After identifying the operation mode of the system as described above, the mode identification unit 255 may transmit the change of the identified operation mode to the communication unit 210 and the display unit 620 through the output unit 258.
이와 같은 모드식별부(255)의 동작에 의하여 본 발명의 일 실시예에 따른 기기 제어 장치는 시스템제어기(200)에 의해 기기가 제어되는 경우 외에, 사용자에 의해 기기가 직접 제어되고 모드가 변경되는 경우에도 이에 따른 동작모드의 변화를 식별할 수 있고, 식별된 상기 동작모드를 출력부(258)를 통해 통신부(210) 또는 표시부(620)로 전송함으로써, 시스템제어기(200)의 관리자가 동작모드를 확인하여 시스템 전체에 대한 통합적인 관리 및 모니터링을 할 수 있다. 즉, 모드식별부(255)의 동작을 통해, 단방향으로만 데이터를 전송할 수 있는 교류전원의 위상각 제어 통신 하에서 연결된 기기(500)의 동작 상태를 피드백 받을 수 있는 효과를 발휘할 수 있다.In the device control apparatus according to an embodiment of the present invention by the operation of the mode identification unit 255 as described above, in addition to the case where the device is controlled by the system controller 200, the device is directly controlled by the user and the mode is changed. In this case, a change in the operation mode may be identified, and the manager of the system controller 200 may operate by transmitting the identified operation mode to the communication unit 210 or the display unit 620 through the output unit 258. You can check the system for integrated management and monitoring of the entire system. That is, through the operation of the mode identification unit 255, it is possible to achieve the effect of receiving the feedback of the operating state of the connected device 500 under the phase angle control communication of the AC power that can transmit data only in one direction.
도 14는 본 발명의 일 실시예에 따른 교류전원의 위상각 제어 통신을 이용한 기기 제어 장치 및 방법의 이상여부판별방법에 따른 내부 구성들의 동작을 개략적으로 도시하는 도면이다.14 is a view schematically showing the operation of the internal components according to the method of determining abnormality of the device control apparatus and method using the phase angle control communication of the AC power according to an embodiment of the present invention.
이상여부판별부(256)는 시스템에 연결된 기기의 동작상태를 파악하여 이상여부를 판별하기 위하여, 입력부에서 전송된 기기모드제어값, 모드데이터저장부에 저장된 데이터, 및 전력량변화계산부가 도출한 전력량변화에 기초하여 동작모드의 이상 여부를 판별한다.The abnormality determining unit 256 checks the operation state of the device connected to the system to determine whether the abnormality is detected, the device mode control value transmitted from the input unit, the data stored in the mode data storage unit, and the amount of power derived from the electric power change calculator. The abnormality of the operation mode is determined based on the change.
이를 위해 상기 이상여부판별부(256)는 상기 입력부(257)로부터 기기모드제어값을 전송 받을 때 마다, 상기 기기모드제어값, 상기 전력량변화계산부(253)가 도출한 전력량변화값, 및 모드데이터저장부(252)에 저장된 동작모드에 대한 전력량 데이터에 기초하여 이상여부를 판별한다.To this end, whenever the abnormality determination unit 256 receives the device mode control value from the input unit 257, the device mode control value, the power amount change value derived by the power amount change calculation unit 253, and the mode. The abnormality is determined based on the power amount data for the operation mode stored in the data storage unit 252.
이상여부판별부(256)는 입력부(257)로부터 기기모드제어값을 전송 받으면 상기 기기모드제어값에 포함된 제어정보를 추출하고, 추출된 상기 제어정보, 전력량변화값, 및 전력량 데이터를 비교함으로써 제어정보에 따른 동작모드가 이상 없이 변화하는지 여부를 판별하게 된다. 이를 통해, 단방향으로만 데이터를 전송할 수 있는 교류전원의 위상각 제어 통신 하에서 연결된 기기(500)의 동작 상태를 판별하고, 이에 따른 이상 여부를 피드백 받을 수 있게 된다.When the abnormality determining unit 256 receives the device mode control value from the input unit 257, the control unit extracts the control information included in the device mode control value, and compares the extracted control information, power change value, and power amount data. It is determined whether the operation mode according to the control information changes without error. Through this, it is possible to determine the operation state of the connected device 500 under the phase angle control communication of the AC power, which can transmit data only in one direction, and receive feedback on the abnormality.
이상여부판별부(256)는 기기모드제어값, 전력량변화값, 및 전력량 데이터에 기초하여 직접 이상 여부를 판별할 수도 있지만, 모드식별부(255)가 전력량변화값 및 전력량 데이터에 기초하여 도출한 동작모드에 기초하여 이상 여부를 판별할 수도 있다. 이 경우 이상여부판별부(256)는 입력부(257)로부터 수신한 기기모드제어값 및 모드식별부(255)로부터 수신한 동작모드를 비교하여 이상 여부를 판별하게 된다.The abnormality determination unit 256 may directly determine whether the abnormality is based on the device mode control value, the power change value, and the power amount data. However, the mode identification unit 255 may derive the power based on the power change value and the power amount data. The abnormality may be determined based on the operation mode.
