Description
본 발명은 발열체를 구비한 태양광 발전 시스템 및 그 제어방법에 관한 것이다.The present invention relates to a solar power generation system having a heating element and a method for controlling the same.
일반적으로 태양에너지를 이용하는 방법은 크게 태양열을 이용하는 방법과 태양광을 이용하는 방법으로 구분된다. 태양열을 이용하는 방법은 태양열에 의해 데워진 물 등을 이용하여 난방 및 발전을 하는 방법으로 태양열 발전이라 하고, 태양광을 이용하는 방법은 태양의 빛을 이용하여 전기를 생산 및 생산된 전기로 각종 기계 및 기구를 작동시킬 수 있도록 하는 방법으로 태양광 발전이라 한다.In general, a method of using solar energy is largely divided into a method using solar heat and a method using sunlight. The method of using solar heat is a method of heating and power generation using water heated by solar heat, and it is called solar power generation. The method of making it work is called solar power generation.
상술한 방법 중 태양광 발전은 실리콘 결정 위에 n형 도핑을 하여 p/n접합을 한 태양전지에 태양광을 조사하면 광 에너지에 의해 전자/정공에 의한 기전력이 발생하게 되는 광기전력 효과(photovoltaic effect)를 이용하여 전기를 발생시킴으로써, 화석원료 등의 기존 에너지원과는 달리 지구 온난화를 유발하는 온실가스 배출, 소음, 환경파괴 등의 위험성이 없는 청정 에너지원이며 고갈의 염려도 없다. 또한 여타 풍력이나 해수력과 달리 태양 광 발전설비는 설치가 자유롭고 유지비용이 저렴하다는 장점을 갖는다.Among the above-described methods, solar power generation is a photovoltaic effect (photovoltaic effect) in which an electromotive force by electrons/holes is generated by light energy when n-type doping on a silicon crystal and irradiating sunlight to a solar cell having a p/n junction ) to generate electricity, unlike existing energy sources such as fossil raw materials, it is a clean energy source that does not cause global warming, such as greenhouse gas emissions, noise, and environmental destruction, and there is no fear of exhaustion. In addition, unlike other wind power or sea water power, solar power generation facilities have the advantage of being free to install and low maintenance costs.
태양광 발전은 태양광을 집광하기 위한 태양전지(solar cell), 태양전지의 집합체인 태양전지모듈(photovoltaicmodule) 및 태양전지들을 일정하게 배열한 태양전지어레이(solar array) 등이 요구된다.Solar power generation requires a solar cell for concentrating sunlight, a photovoltaic module that is an assembly of solar cells, and a solar array in which solar cells are uniformly arranged.
그러나, 현재 가장 널리 사용되고 있는 실리콘 태양전지의 경우 태양전지모듈의 온도가 올라갈 경우 1℃ 당 05%의 출력 감소가 발생한다. 이러한 특성에 따라 태양광 발전의 출력은 태양이 가장 긴 여름이 아닌 봄과 가을에 최고치를 기록한다. 이러한 온도 상승은 태양광 발전의 발전 효율이 저하되는 주요 원인이 되고 있다. 또한, 태양전지모듈에 황사, 악천후 등의 기상현상 등에 의해 오물이 쉽게 쌓일 수 있다는 단점을 갖는다. 태양전지모듈에 오물이 쌓일 경우 태양전지모듈은 광투과 및 광흡수율이 현저히 떨어지므로 발전효율이 저하되며, 겨울철에 비나 눈 등이 태양 전지판에 내릴 경우 발전효율의 저하가 발생한다.However, in the case of silicon solar cells, which are currently most widely used, when the temperature of the solar cell module increases, an output decrease of 05% per 1°C occurs. According to these characteristics, the output of photovoltaic power peaks in spring and autumn, not in summer, when the sun is the longest. This temperature rise is a major cause of the deterioration of the power generation efficiency of solar power generation. In addition, it has a disadvantage that dirt may easily accumulate on the solar cell module due to weather phenomena such as yellow sand or bad weather. When dirt accumulates on the solar cell module, the light transmittance and light absorptivity of the solar cell module is significantly lowered, so the power generation efficiency is lowered.
따라서, 이러한 오물, 눈, 비로 인한 발전효율의 저하의 방지를 위해 태양광 발전설비 유지장치가 사용된다. 태양광 발전의 효율을 향상시키기 위한 설비는 태양전지모듈의 온도를 식혀주는 냉각 작용과 태양전지모듈에 쌓인 오물, 눈, 우수 등을 세척, 제설 등을 함으로써 태양전지모듈이 일정한 출력의 발전을 수행할 수 있도록 태양광 발전설비를 유지관리하는 기능을 한다.Therefore, in order to prevent a decrease in power generation efficiency due to such filth, snow, and rain, a solar power generation facility maintenance device is used. A facility to improve the efficiency of solar power generation is a cooling action that cools the temperature of the solar cell module and washing and snow removal accumulated on the solar cell module such as dirt, snow, rainwater, etc. It functions to maintain and manage solar power generation facilities.
특히, 태양전지모듈에 눈이 쌓일 경우에는 발전효율의 저하 및 하중에 의한 손상이 발생될 수 있음에 따라 눈이 내리때, 신속하여 발열하여 태양전지모듈에 눈이 쌓이는 것을 방지함이 바람직하다. In particular, when snow accumulates on the solar cell module, it is desirable to prevent the accumulation of snow on the solar cell module by rapidly generating heat when it snows, as a decrease in power generation efficiency and damage due to a load may occur.
따라서 종래에는 태양전지모듈의 배면에 발열체를 구비하여 태양전지모듈을 가열하는 방식으로 눈을 녹여서 제거하는 기술이 제안되었다. 하지만, 이경우에 다수의 태양전지모듈별로 설치되는 복수의 발열체를 동시에 가열함에 따라 공급전력의 소비가 많은 문제점이 있었다. Therefore, conventionally, a technique for removing snow by melting snow by heating the solar cell module by providing a heating element on the rear surface of the solar cell module has been proposed. However, in this case, as a plurality of heating elements installed for each solar cell module are simultaneously heated, there is a problem in that supply power is consumed.
따라서 본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 복수의 발열체들에 순차적으로 전원을 공급하여 공급전력을 줄일 수 있는 발열체를 구비한 태양광 발전 시스템 및 그 제어 방법을 제공함에 있다. Accordingly, the present invention has been devised to solve the problems of the related art as described above, and an object of the present invention is a solar power generation system having a heating element capable of reducing supply power by sequentially supplying power to a plurality of heating elements, and a photovoltaic power generation system and the same To provide a control method.

An embodiment according to the present invention includes a plurality of solar cell modules and one or more heating elements, and is installed on the rear surface of the solar cell module to generate heat, and a sensor unit for detecting the amount of snow and temperature, and heat according to the sensing information of the sensor unit a heater controller for controlling the unit, wherein a plurality of the heating units form one group, each group is connected in series to the heater controller, and the heater controller has a delay time set for each group of the heating units according to the sensing information of the sensor unit. It is possible to provide a solar power generation system having a heating element, characterized in that it operates sequentially.
그러므로 본 발명은 다수개의 발열체를 그룹화하고, 각 그룹별로 시간차를 두고 순차 작동시킴에 따라 공급 전력을 절약할 수 있는 효과가 있다. Therefore, the present invention has the effect of saving power supply by grouping a plurality of heating elements and sequentially operating each group with a time difference.
또한, 본 발명은 발열체들로부터 발열된 태양전지모듈의 전체 영역으로 전도시킬 수 있어 발열체의 숫자를 줄일 수 있어 비용 및 에너지를 절약할 수 있는 효과가 있다. In addition, the present invention can conduct heat from the heating elements to the entire area of the solar cell module, thereby reducing the number of heating elements, thereby saving cost and energy.

Each group A and B of the heat generating unit 60 is electrically connected in series with the heater controller 10 . In addition, the heating units 60 belonging to the same group (A, B) are connected in parallel to each other.
따라서 발열부(60)는 그룹(A, B)별로 순차 온되되, 동일 그룹(A, B)에 속한 발열부(60)들은 동시 온 또는 오프 될 수 있다. 예를 들면, 제1발열부(60) 그룹(A)과 제2발열부(60) 그룹(B)은 히터 컨트롤러(10)와 직렬 연결된다. 따라서 히터 컨트롤러(10)는 제1발열부(60) 그룹(A)에 공급전원을 공급한 뒤, 설정된 지연시간 이후에 제2발열부(60) 그룹(B)에 전원을 공급하여 작동시킨다. Accordingly, the heating units 60 are sequentially turned on for each group (A, B), and the heating units 60 belonging to the same group (A, B) may be turned on or off at the same time. For example, the first heat generating unit 60 group A and the second heat generating unit 60 group B are connected in series with the heater controller 10 . Therefore, the heater controller 10 supplies power to the first heat generating unit 60 group (A), and then supplies power to the second heat generating unit 60 group (B) after a set delay time to operate it.
이때, 동일 그룹(A, B)에 속한 발열부(60)들은 상호 병렬 연결됨에 따라 전원이 공급됨과 동시에 온된다.At this time, the heating units 60 belonging to the same group (A, B) are turned on at the same time power is supplied as they are connected in parallel with each other.

Here, the control module 130 may control the switching module 140 to sequentially operate each heat generating unit 60 for each set group (A, B).
예를 들면, 복수의 발열부(60)를 동시에 작동시킬 경우에는 소비전력보다 필요 이상으로 많은 공급 전력이 필요하다. 따라서 히터 컨트롤러(10)는 이와 같은 공급전력을 절감시킬 수 있도록 발열부(60)들을 그룹화하고, 각 발열부(60) 그룹(A, B)들을 지연시간을 사이에 두고 순차 작동시키는 것을 특징으로 한다. For example, when the plurality of heat generating units 60 are simultaneously operated, more power than necessary is supplied than power consumption.

The operation module 120 calculates the power consumption for each heat generating unit 60 or each heat generating unit 60 grouped into a plurality of heat generating units 60 (A, B) for each group (A, B). Here, information on power consumption for each light emitting unit group (A, B) calculated by the operation module 120 is output to the control module 130 .
제어모듈(130)은 설정된 소비전력과 연산된 소비전력을 비교하여 설정된 범위 이내에 해당되지 않으면 표시모듈(150)을 제어하여 고장발생을 표시하고, 통신모듈(110)을 제어하여 원격 제어부(90) 및/또는 모바일 단말(도시되지 않음)에 고장 경보를 송신하도록 제어한다.

The switching module 140 energizes the output power line of the power supply unit 40 and the power line connected to each group (A, B) of the heating unit 60 under the control of the control module 130 . For example, the switching module 140 turns on the first power line and the power supply unit 40 connected to the group A of the first heating unit 60 under the control of the control module 130, and after a set delay time In the second heat generating unit 60, the power line between the second power line connected to the group (B) and the power supply unit 40 is energized.

발열체(61, 61')들은, 예를 들면, 제1발열체(61)와 제2발열체(61')로서 상호 이격되어 설치되며, 각각 기판(611)과 발열체(61)와 보호층(613)과 단열재(615) 및/또는 접착층(614)으로 구성된다. 이때 제1발열체(61)와 제2발열체(61')는 전원 커넥터 기판(623)에 전기적으로 통전되도록 연결되되, 상호 병렬 연결된다. The heating elements 61 and 61' are installed to be spaced apart from each other as, for example, the first heating element 61 and the second heating element 61', respectively, the substrate 611, the heating element 61, and the protective layer 613. and a heat insulating material 615 and/or an adhesive layer 614 . At this time, the first heating element 61 and the second heating element 61 ′ are electrically connected to the power connector board 623 , and are connected in parallel with each other.
열전도 시트(65)는 복수의 발열체(61, 61')들 상면에 적층되어 열을 전도한다. 예를 들면, 열전도 시트(65)는 절연 재질의 수지층(651)과, 수지층(651) 내에 매립된 열전도 금속 와이어(652)를 포함할 수 있다. The heat conduction sheet 65 is laminated on the upper surfaces of the plurality of heating elements 61 and 61' to conduct heat. For example, the heat conductive sheet 65 may include a resin layer 651 made of an insulating material and a heat conductive metal wire 652 embedded in the resin layer 651 .
여기서 발열체(61)의 접착층(614)은 양면 테이프로서 수지층(651)의 상면에 도포된다. Here, the adhesive layer 614 of the heating element 61 is applied to the upper surface of the resin layer 651 as a double-sided tape.
또는 열전도 시트(65)는 접착층(614)의 상면에 적층될 수 있다. 이 경우 열전도 시트(65)는 별도의 양면 테이프에 의해 태양전지판(51)의 배면에 임시 접착된 후 지지수단(62)에 의해 완전 고정될 수 있다. Alternatively, the heat conductive sheet 65 may be laminated on the upper surface of the adhesive layer 614 . In this case, the heat conduction sheet 65 may be temporarily attached to the rear surface of the solar panel 51 by a separate double-sided tape and then completely fixed by the support means 62 .
수지층(651)은 절연 가능한 액상의 수지가 도포 및 경화되어 내측에 매립된 열전도 금속 와이어(652)를 절연시킨다. The resin layer 651 insulates the heat-conducting metal wire 652 embedded therein by applying and curing an insulating liquid resin.
열전도 금속 와이어(652)는 수지층(651)에 매립된 형태로 연장되어 발열체(61)들로부터 발생된 열을 태양전지판(51)의 배면 전체에 전도한다. 여기서 열전도 금속 와이어(652)는 가로 및 세로 방향으로 교차 연장됨에 따라 메쉬형으로 형성될 수 있다. 열전도 금속 와이어(652)는 태양전지판(51)의 배면 전체에 설치될 수 있는 면적으로 제조 됨이 바람직하다. The heat-conducting metal wire 652 extends in a form embedded in the resin layer 651 to conduct heat generated from the heating elements 61 to the entire rear surface of the solar panel 51 . Here, the heat-conducting metal wire 652 may be formed in a mesh shape as it cross-extends in the horizontal and vertical directions. The heat-conducting metal wire 652 is preferably manufactured in an area that can be installed on the entire rear surface of the solar panel 51 .

In general, the solar cell module 50 may vary in real time according to the position of sunlight. Therefore, the present invention can also be applied to a solar cell module to which a solar tracking device capable of changing the posture of the solar cell module 50 according to the position of the sun as described above is added. This will be described with reference to FIGS. 11 and 12 .
도 11 및 도 12는 본 발명에서 태양전지모듈의 다른 실시예를 도시한 도면이다. 11 and 12 are views showing another embodiment of the solar cell module in the present invention.
도 11과 도 12를 참조하면, 본 발명은 태양전지모듈(50)의 위치를 변형하는 회동부(80)와, 히터 컨트롤러(10)의 제어에 의하여 회동부(80)를 작동시키는 회동 구동부(70)를 포함할 수 있다. 또한, 회동부(80)는 일반적으로 공지된 태양전지모듈(50)의 트래킹 장치에 적용되는 기술을 적용함에 따라 주요 구성과 원리만으로 간략하게 설명한다. 다만, 이하에서 설명하는 회동부(80)는 본 발명을 한정하는 것이 아니며, 태양전지모듈(50)을 위치를 변형시킬 수 있는 모든 장치에 해당된다.11 and 12 , the present invention provides a rotational part 80 that deforms the position of the solar cell module 50 and a rotational driving part that operates the rotational part 80 under the control of the heater controller 10 ( 70) may be included. In addition, the rotating unit 80 will be briefly described with only the main configuration and principle as the technology applied to the tracking device of the generally known solar cell module 50 is applied. However, the rotation unit 80 to be described below does not limit the present invention, and corresponds to any device capable of changing the position of the solar cell module 50 .
회동 구동부(70)는 히터 컨트롤러(10) 또는 원격 제어부(90)의 제어에 의하여 태양전지모듈(50)에 설치된 회동부(80)를 구동시킨다. The rotation driving unit 70 drives the rotation unit 80 installed in the solar cell module 50 under the control of the heater controller 10 or the remote control unit 90 .
회동부(80)는 회동 구동부(70)의 제어에 의하여 작동되는 실린더(81)와, 실린더(81)에 연결되는 회동바(82)와, 태양전지모듈(50)과 회동바(82) 사이에서 회전가능하게 연결되는 연결바(83)와, 태양전지모듈(50)을 지지하는 지지바(84)를 포함한다. The rotation unit 80 is between the cylinder 81 operated by the control of the rotation driving unit 70 , the rotation bar 82 connected to the cylinder 81 , and the solar cell module 50 and the rotation bar 82 . It includes a connection bar 83 that is rotatably connected in the and a support bar 84 for supporting the solar cell module 50 .
실린더(81)는 회동 구동부(70)로부터 작동 명령이 입력되면, 회동바(82)를 전방 또는 후방으로 이동시킨다. When an operation command is inputted from the rotation driving unit 70 , the cylinder 81 moves the rotation bar 82 forward or backward.
지지바(84)는 회동바(82)와 태양전지모듈(50) 사이에 회전 가능하게 연결된다. 즉, 지지바(84)는 회동바(82)가 전방으로 이동되면, 태양전지모듈(50)을 반시계 방향 또는 시계 방향으로 회전시킨다. The support bar 84 is rotatably connected between the rotation bar 82 and the solar cell module 50 . That is, the support bar 84 rotates the solar cell module 50 counterclockwise or clockwise when the rotation bar 82 is moved forward.
따라서 히터 컨트롤러(10)는 적설센서(21)의 감지신호에 따라 적설량을 감지하고, 감지된 적설량이 설정된 기준을 초과하면, 회동 구동부(70)를 제어하여 태양전지모듈(50)을 직립된 자세로 유지하도록 제어한다. Therefore, the heater controller 10 detects the amount of snow according to the detection signal of the snow sensor 21, and when the detected amount of snow exceeds the set standard, controls the rotation driving unit 70 to set the solar cell module 50 in an upright position. control to keep
이는 발열체(61)에 의해 눈이 녹는 시간 대비 눈이 쌓이는 시간이 더 빠를 경우에 태양전지모듈(50)을 직립된 자세로 변형하여 눈이 쌓이는 것을 방지할 수 있다. This can prevent snow accumulation by deforming the solar cell module 50 to an upright posture when the snow accumulation time is faster than the snow melting time by the heating element 61 .
본 발명은 상기와 같은 구성을 포함하며, 이하에서는 상기와 같은 구성을 이용하는 발열체(61)가 구비된 태양광 발전 시스템의 제어방법을 설명한다. The present invention includes the configuration as described above, and below, a control method of a solar power generation system having the heating element 61 using the configuration as described above will be described.
도 13은 발열체가 구비된 태양광 발전 시스템의 제어방법을 도시한 순서도이다. 13 is a flowchart illustrating a control method of a solar power generation system provided with a heating element.
도 13을 참조하면, 본 발명은 히터 컨트롤러(10)가 센서부(20)로부터 감지 정보를 수집하는 S100 단계와, 설정된 기준과 감지정보를 비교하는 S200 단계와, 발열부(60) 그룹(A, B)별로 순차 작동시키는 S300 단계와, 비상 스위치(30)의 온오프를 감지하는 S400 단계와, 비상 스위치(30)가 온되면 전원을 차단하여 발열체(61)들을 오프시키는 S500 단계를 포함한다. 13, in the present invention, the heater controller 10 collects detection information from the sensor unit 20, step S100, comparing the detection information with a set standard, step S200, and the heating unit 60 group (A) , step S300 of sequentially operating each B), step S400 of detecting on/off of the emergency switch 30, and step S500 of turning off the heating elements 61 by cutting off the power when the emergency switch 30 is turned on. .
S100 단계는 히터 컨트롤러(10)가 센서부(20)의 감지 정보를 수집하는 단계이다. 히터 컨트롤러(10)는 적설센서(21)의 적설량 감지 정보와, 온도센서(22)의 온도 감지 정보와, 풍속센서(23)의 풍속 감지 정보와, 수량센서(24)의 강우량 감지 정보를 수신한다. Step S100 is a step in which the heater controller 10 collects detection information of the sensor unit 20 . The heater controller 10 receives snow amount detection information of the snow load sensor 21 , temperature detection information of the temperature sensor 22 , wind speed detection information of the wind speed sensor 23 , and rainfall detection information of the water quantity sensor 24 . do.
S200 단계는 히터 컨트롤러(10)가 감지 정보와 설정된 정보를 비교하는 단계이다. 예를 들면, 히터 컨트롤러(10)는 적설량과 온도와 풍속 및 강우량에 따라 발열체(61)를 작동시킬 수 있는 기준이 설정된다. 예를 들면, 발열체(61)는 눈이 오거나 눈이 그치더라도 온도가 설정 온도 이하이거나 풍속이 설정값을 초과할 경우와, 비가 오거나 그친 뒤에 설정 온도 이하 및/또는 설정된 풍속 이상이 감지되면 작동될 수 있다. Step S200 is a step in which the heater controller 10 compares detected information with set information. For example, the heater controller 10 sets a standard for operating the heating element 61 according to the amount of snow, temperature, wind speed, and rainfall. For example, the heating element 61 may be operated when the temperature is below the set temperature or the wind speed exceeds the set value even when it snows or snows stop, and when it is detected below the set temperature and/or the set wind speed or more after it rains or stops can
즉, 히터 컨트롤러(10)는 적설량과, 강우량, 온도 및 풍속이 조합되는 기준들이 설정될 수 있다. That is, the heater controller 10 may set criteria for combining the amount of snow, rainfall, temperature, and wind speed.
S300 단계는 히터 컨트롤러(10)가 S200 단계에서 감지 정보가 설정된 조건에 해당되면, 발열체(61)들을 순차 작동시키는 단계이다. 여기서 발열체(61)를 포함하는 발열부(60)들은 복수의 그룹(A, B)으로 설정되고, 각 발열부(60) 그룹(A, B)은 히터 컨트롤러(10)에 직렬 연결된다. 또한 동일 그룹(A, B)내에 속한 발열체(61)들은 병렬 연결된다. Step S300 is a step in which the heater controller 10 sequentially operates the heating elements 61 when the detection information corresponds to the condition set in step S200 . Here, the heating units 60 including the heating element 61 are set in a plurality of groups A and B, and each of the heating units 60 groups A and B is connected in series to the heater controller 10 . In addition, the heating elements 61 belonging to the same group (A, B) are connected in parallel.
그러므로 히터 컨트롤러(10)는, 예를 들면, 제1발열부(60) 그룹(A)을 작동시킨 후 설정된 지연시간이 경과된 후 제2발열부(60) 그룹(B)을 작동시킨다. 이와 같이 히터 컨트롤러(10)는 설정된 지연시간을 주기로 발열부(60) 그룹(A, B)들을 순차 작동시킨다. Therefore, the heater controller 10, for example, operates the second heat generating unit 60 group (B) after a set delay time elapses after operating the first heat generating unit (60) group (A). As described above, the heater controller 10 sequentially operates the groups A and B of the heating unit 60 at a set delay time period.
여기서 히터 컨트롤러(10)의 스위칭모듈(140)은 전원부(40)의 출력 전원라인과, 해당 발열부(60) 그룹(A, B)에 연결되는 전원라인을 순차 연결시킨다. 따라서 전원부(40)에서 출력되는 공급전원은 전체 발열부(60) 그룹(A, B)을 동시 작동시키기 위한 것이 아니라 발열부(60) 그룹(A, B)별로 순차 공급됨에 따라 절감될 수 있다. Here, the switching module 140 of the heater controller 10 sequentially connects the output power line of the power supply unit 40 and the power line connected to the corresponding heating unit 60 groups A and B. Therefore, the supply power output from the power supply unit 40 is not for simultaneously operating the entire heating unit 60 group (A, B), but can be reduced as it is sequentially supplied for each heating unit 60 group (A, B). .
S400 단계는 히터 컨트롤러(10)가 비상 스위치(30)의 온오프를 감지하는 단계이다. 여기서 비상 스위치(30)는 관리자가 수동 조작이 가능한 것으로서 히터 컨트롤러(10)와 일체로 구비됨도 가능하다. Step S400 is a step in which the heater controller 10 detects on/off of the emergency switch 30 . Here, the emergency switch 30 may be manually operated by an administrator and may be provided integrally with the heater controller 10 .
또는 원격 제어부(90)에서 원격으로 비상 스위치(30)를 제어하거나, 비상 정지 명령을 송신함도 가능하다. Alternatively, the remote control unit 90 may remotely control the emergency switch 30 or transmit an emergency stop command.
따라서 히터 컨트롤러(10)는 발열체(61)가 작동된 이후에 비상 스위치(30)가 온 또는 원격 제어부(90)의 비상 정지 명령의 수신 여부를 감지한다. Accordingly, the heater controller 10 detects whether the emergency switch 30 is turned on or an emergency stop command from the remote control unit 90 is received after the heating element 61 is operated.
S500 단계는 히터 컨트롤러(10)는 비상 정지 명령이 수신되면, 발열부(60) 그룹(A, B)을 오프시키는 단계이다. 예를 들면, 스위칭모듈(140)은 비상 스위치(30)가 온 또는 원격 제어부(90)에서 비상 정지 명령이 수신되면, 전원부(40)와 발열부(60) 그룹(A, B)별로 직렬 연결되는 전원라인을 차단한다. Step S500 is a step in which the heater controller 10 turns off the groups A and B of the heating unit 60 when an emergency stop command is received. For example, when the emergency switch 30 is turned on or an emergency stop command is received from the remote control unit 90 , the switching module 140 is connected in series with the power supply unit 40 and the heating unit 60 for each group (A, B). cut off the power line.
이중 S300 단계는 적설량에 따른 태양전지모듈(50)을 직립제어하는 S310 단계와, 발열부(60) 그룹(A, B)들의 고장 여부를 감지하는 S320 단계를 포함할 수 있다. 이는 도 14와 15를 참조하여 설명한다. Of these, step S300 may include a step S310 for vertically controlling the solar cell module 50 according to the amount of snow, and a step S320 for detecting whether or not the groups A and B of the heating unit 60 are faulty. This will be described with reference to FIGS. 14 and 15 .
도 14는 S310 단계를 도시한 순서도이다. 14 is a flowchart illustrating step S310.
도 14를 참조하면, S310 단계는 적설을 감지하는 S311 단계와, 발열부(60) 그룹(A, B)별로 순차 구동시키는 S312 단계와, 설정된 제1 적설량과 감지된 적설량을 비교하는 S313 단계와, 설정된 제1적설량을 초과한 적설량이 감지되면 시간 기준을 비교하는 S314 단계와, 설정 시간기준에 해당되지 않으면 감지된 적설량과 설정된 제2적설량을 비교하는 S315 단계와, 설정 시간 기준 또는 설정 제2적설량에 해당되면 태양전지모듈(50)을 직립 제어하는 S316 단계와, 온도 및/또는 풍속 기준에 따라 차등 주기로 발열부(60) 그룹(A, B)을 제어하는 S317 단계를 포함한다. Referring to FIG. 14 , step S310 includes step S311 of detecting snow load, step S312 of sequentially driving for each group (A, B) of the heat generating unit 60, step S313 of comparing the set first snow load amount with the detected snow amount, and , a step S314 of comparing a time reference when a snow load exceeding the set first snow load is detected, a step S315 of comparing the detected snow amount with a set second snow amount if it does not correspond to a set time standard, a set time standard or a set second When the amount of snow falls, a step S316 of controlling the solar cell module 50 upright, and a step S317 of controlling the groups (A, B) of the heat generating units 60 at a differential cycle according to the temperature and/or wind speed standard are included.
S311 단계는 히터 컨트롤러(10)가 적설센서(21)의 감지 정보를 수신하는 단계이다. 히터 컨트롤러(10)는 실시간으로 센서부(20)의 감지 정보를 수신한다.Step S311 is a step in which the heater controller 10 receives detection information of the snow load sensor 21 . The heater controller 10 receives sensing information of the sensor unit 20 in real time.
S312 단계는 히터 컨트롤러(10)는 적설이 감지되면, 발열부(60) 그룹(A, B)별로 순차 작동시키는 단계이다. 히터 컨트롤러(10)는 눈이 내리기 시작하면, 발열부(60) 그룹(A, B)별로 순차 작동시킨다. 이때 히터 컨트롤러(10)는 복수의 발열부(60) 그룹(A, B) 중 어느 하나가 작동된 이후에 설정된 지연시간이 경과되면 다음 차순의 발열부(60) 그룹(A, B)에 전원을 공급하도록 제어한다. Step S312 is a step in which the heater controller 10 sequentially operates for each group (A, B) of the heating unit 60 when snow is detected. When the snow starts to fall, the heater controller 10 sequentially operates the heating unit 60 for each group (A, B). At this time, when the set delay time elapses after any one of the plurality of heat generating units 60 groups A and B is operated, the heater controller 10 supplies power to the next heat generating unit 60 groups A and B. control to supply
S313 단계는 히터 컨트롤러(10)는 적설센서(21)로부터 적설량 감지 정보를 수신하여 설정된 제1 적설량과 비교한다. 여기서 히터 컨트롤러(10)는 발열체(61)가 작동된 이후라도 적설센서(21)의 감지정보를 계속적으로 수신하여 감지된 눈의 적설량과 설정된 제1적설량을 비교한다. In step S313 , the heater controller 10 receives the snow load amount detection information from the snow load sensor 21 and compares it with a set first snow load amount. Here, the heater controller 10 continuously receives the detection information of the snow load sensor 21 even after the heating element 61 is operated and compares the sensed snow load amount with the set first snow load amount.
S314 단계는 히터 컨트롤러(10)가 설정된 제1적설량이 감지되면, 설정된 시간 기준의 해당 여부를 감지하는 단계이다. 예를 들면, 시간 기준은 일몰 후 부터 일출 이전의 시간 대를 포함할 수 있다. 따라서 히터 컨트롤러(10)는 자체 타이머를 통하여 현재 시간과 시간 기준을 비교한다.Step S314 is a step in which the heater controller 10 detects whether the set first snowfall amount corresponds to the set time reference. For example, the time reference may include a time zone from after sunset to before sunrise. Accordingly, the heater controller 10 compares the current time with the time reference through its own timer.
S315 단계는 히터 컨트롤러(10)가 현재 시간이 시간 기준에 해당되지 않으면, 적설센서(21)로부터 감지된 적설량이 설정된 제2적설량에 해당되는 지를 감지하는 단계이다. 여기서 제2적설량은 제1적설량 보다 큰 값으로 설정된다. In step S315 , if the current time does not correspond to the time reference, the heater controller 10 detects whether the snow load amount detected by the snow load sensor 21 corresponds to the set second snow load amount. Here, the second snow load is set to be larger than the first snow load.
S316 단계는 히터 컨트롤러(10)가 시간 기준 또는 제2적설량이 감지되면 태양전지모듈(50)을 직립 제어하는 단계이다. 히터 컨트롤러(10)는 적설센서(21)의 감지정보에 따라 설정된 적설량에 해당되면, 회동 구동부(70)에 작동명령을 출력한다. Step S316 is a step in which the heater controller 10 controls the solar cell module 50 upright when the time reference or the second snow load is sensed. The heater controller 10 outputs an operation command to the rotation driving unit 70 when it corresponds to the snow load amount set according to the detection information of the snow load sensor 21 .
따라서 회동 구동부(70)는 회동부(80)를 작동시켜 태양전지모듈(50)을 직립된 자세로 변형시킨다. 그러므로 태양전지모듈(50)은 직립된 자세를 유지함에 따라 기존에 쌓인 눈을 모두 지면으로 낙하시키고, 이후에 적설되는 눈의 양을 최소화할 수 있다. Therefore, the rotation driving unit 70 operates the rotation unit 80 to transform the solar cell module 50 into an upright posture. Therefore, as the solar cell module 50 maintains an upright posture, all of the previously accumulated snow may fall to the ground, and the amount of snow accumulated thereafter may be minimized.
S317 단계는 히터 컨트롤러(10)가 센서부(20)의 감지정보에 따라서 발열부(60) 그룹(A, B)들을 차등 주기로 작동되도록 제어하는 단계이다. 예를 들면, 히터 컨트롤러(10)는 태양전지모듈(50)의 직립 후에 온도와 풍속, 시간에 따라서 발열부(60) 그룹(A, B)이 설정된 시간동안 온과 오프를 교번적으로 진행할 수 있도록 제어한다. Step S317 is a step in which the heater controller 10 controls the groups A and B of the heating units 60 to operate in a differential cycle according to the sensing information of the sensor unit 20 . For example, after the solar cell module 50 is erected, the heater controller 10 may alternately turn on and off for a set period of time for which the heating unit 60 groups A and B are set according to temperature, wind speed, and time. control so that
예를 들면, 히터 컨트롤러(10)는 온도가 낮고 풍속이 강할 수록 발열부(60) 그룹(A, B)들의 온되는 시간이 길고, 오프 시간이 짧아지도록 제어한다. For example, the heater controller 10 controls so that the on time of the groups A and B of the heating unit 60 is longer and the off time is shorter as the temperature is lower and the wind speed is stronger.
또한, 히터 컨트롤러(10)는 S317 단계에서 발열체(61) 오프 기준 및/또는 직립 해제 조건에 해당되면 발열체(61)를 오프 및/또는 직립을 해제할 수 있다. Also, the heater controller 10 may turn the heating element 61 off and/or release the upright position when the heating element 61 off criterion and/or the upright release condition are met in step S317 .
발열체(61)의 오프 기준은 온도(예를 들면, 20℃ 이상)와 풍속과 강우량 중 어느 하나 또는 하나 이상이 조합되도록 설정될 수 있고, 직립 해제 조건은 시간과 적설량 및 온도 중 하나 이상이 조합될 수 있다. The off criterion of the heating element 61 may be set such that any one or more of temperature (eg, 20° C. or higher), wind speed, and rainfall are combined, and the upright release condition is a combination of time, snow load, and temperature. can be
S320 단계는 도 15를 참조하여 설명한다. 도 15는 S320 단계에서 고장 감지 단계를 도시한 순서도이다. Step S320 will be described with reference to FIG. 15 . 15 is a flowchart illustrating a failure detection step in step S320.
도 15를 참조하면, S320 단계는 히터 컨트롤러(10)에서 각 발열부(60) 그룹(A, B)별 소비전력을 측정하는 S321 단계와, 발열부(60) 그룹(A, B) 중 소비전력과 설정된 소비전력에 차이 여부에 따른 발열부(60) 그룹(A, B)의 이상을 감지하는 S322 단게와, 이상이 있는 것으로 감지되면 설정 시간 동안 대기하는 S323 단계와, 대기시간 이후에 소비전력을 재측정하는 S324 단계와, 재측정 이후에 고장을 감지하는 S325 단계와, 고장 경보를 출력 및 송신하는 S326 단계를 포함한다. Referring to FIG. 15 , step S320 includes a step S321 of measuring power consumption for each group (A, B) of each heating unit 60 in the heater controller 10, and a consumption among groups (A, B) of the heating unit 60 Step S322 for detecting an abnormality in the group (A, B) of the heating unit 60 according to whether there is a difference between power and set power consumption, and step S323 for waiting for a set time when an abnormality is detected, and consumption after the standby time Step S324 of re-measuring power, step S325 of detecting a failure after re-measurement, and step S326 of outputting and transmitting a failure alert.
S321 단계는 히터 컨트롤러(10)가 각 발열부(60) 그룹(A, B)별 소비전력을 측정하는 단계이다. 연산모듈(120)은 스위칭모듈(140)에 의해 전원이 공급되는 각 발열부(60) 그룹(A, B)별로 소비전력을 산출한다. 여기서 연산 모듈은 설정된 시간 주기별로 소비전력을 측정하고, 제어모듈(130)은 연산모듈(120)에서 산출된 각 발열부(60) 그룹(A, B)의 소비전력과 설정된 소비전력 기준을 비교하여 이상 여부를 감지한다. Step S321 is a step in which the heater controller 10 measures the power consumption for each heat generating unit 60 group (A, B). The operation module 120 calculates power consumption for each group (A, B) of each heat generating unit 60 supplied with power by the switching module 140 . Here, the arithmetic module measures power consumption for each set time period, and the control module 130 compares the set power consumption standard with the power consumption of each heat generating unit 60 group (A, B) calculated by the arithmetic module 120 . to detect any abnormality.
예를 들면, 제1발열부(60) 그룹(A)은 제1발열체(61)와 제2발열체(61')를 포함하고, 이중 제1발열체(61)가 고장으로 작동되지 않고, 제2발열체(61')만 작동될 수 있다. 그러므로 제1발열부(60) 그룹(A)은 하나의 발열체(61, 61')만 작동됨에 따라 소비전력이 정상 작동에 비하여 반값으로 떨어진다. For example, the first heating unit 60 group (A) includes a first heating element 61 and a second heating element 61 ′, among which the first heating element 61 is not operated due to a failure, and the second Only the heating element 61' can be operated. Therefore, in the group (A) of the first heating unit 60, as only one heating element (61, 61') is operated, the power consumption is reduced to half compared to the normal operation.
그리고 소비전력 기준은 발열부(60) 그룹(A, B)이 작동될 경우에 사용되는 소비전력의 범위로 설정된다. And the power consumption standard is set to the range of power consumption used when the heating unit 60 group (A, B) is operated.
따라서 제어모듈(130)은 연산모듈(120)에서 산출된 실제 소비전력과 설정된 소비전력 기준을 통하여 이상 여부를 감지할 수 있다. Accordingly, the control module 130 may detect whether there is an abnormality based on the actual power consumption calculated by the operation module 120 and the set power consumption standard.
S323 단계는 히터 컨트롤러(10)에서 설정된 시간동안 대기하는 단계이다. Step S323 is a step of waiting for a time set in the heater controller 10 .
S324 단계는 히터 컨트롤러(10)에서 S322 단계에서 이상이 감지된 발열부(60) 그룹(A, B)의 소비전력을 대기시간 이후에 재측정하는 단계이다. 연산모듈(120)은 대기시간 이후에 설정된 시간동안 해당 발열부(60) 그룹(A, B)의 소비전력을 재측정하여 그 결과를 출력한다.Step S324 is a step in which the heater controller 10 re-measures the power consumption of the groups A and B of the heating unit 60 for which the abnormality is detected in step S322 after the standby time. The operation module 120 re-measures the power consumption of the group (A, B) of the heating unit 60 for a set time after the standby time, and outputs the result.
S325 단계는 히터 컨트롤러(10)에서 재측정된 소비전력과 설정된 소비전력 기준을 비교하여 고장여부를 감지하는 단계이다. 제어모듈(130)은 연산모듈(120)의 재측정된 소비전력과 설정된 소비전력 기준과의 차이 여부를 통하여 고장을 감지한다. Step S325 is a step of detecting whether there is a failure by comparing the re-measured power consumption by the heater controller 10 with a set power consumption standard. The control module 130 detects a failure based on whether there is a difference between the re-measured power consumption of the operation module 120 and the set power consumption standard.
S326 단계는 히터 컨트롤러(10)에서 재측정된 소비전력이 설정된 소비전력 기준과 상이할 경우에 고장을 경보하는 단계이다. 고장경보는 원격 제어부(90)와, 모바일 단말(도시되지 않음)에 직접 송신될 수 있다. 또는 히터 컨트롤러(10)는 표시모듈(150)을 작동시켜 고장 여부를 발광 표시함도 가능하다. Step S326 is a step of alerting a failure when the power consumption re-measured by the heater controller 10 is different from the set power consumption standard. The failure alarm may be transmitted directly to the remote control unit 90 and a mobile terminal (not shown). Alternatively, the heater controller 10 may operate the display module 150 to display whether there is a malfunction or not.
