이하, 첨부된 도면 도 1 및 도 2 를 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, FIGS. 1 and 2.

도 1 은 본 발명의 구현을 위한 고속전철의 에어콤프레서 제어장치를 도시한 것으로서,1 shows an air compressor control apparatus of a high speed train for implementing the present invention,

선두동력차와 후부동력차에는 각각 압력상태에 따라 콤프레서의 동작을 제어하는 선두SCU(1)와 후부SCU(11)가 구성되고, 동력차 내부의 에어압 충전상태를 감지하는 선두압력감지부(2)와 후부압력감지부(12)가 구성되며, SCU(1,11)의 제어에 따라 동작하여 에어압이 충진되도록 하는 선두동력차와 후부동력차의 메인콤프레서(3,13)와 보조콤프레서(4,14)로 구성된다.The head and rear power differentials each include a head SCU 1 and a rear SCU 11 that control the operation of the compressor according to the pressure state, and a head pressure sensing unit 2 for sensing the air pressure charging state inside the power vehicle. The rear pressure sensing unit 12 is configured and operates under the control of the SCUs 1 and 11, and the main compressors 3 and 13 and the auxiliary compressors 4 and 14 of the front power difference and the rear power difference to fill the air pressure. It consists of.

상기 선두SCU(1)와 후부SCU(11)는 운전실이 선두동력차 또는 후부동력차로 선택되었을때 고속전철의 전반적인 동작을 제어하는 기능을 담당하며, 압력감지부(2,22)에서 감지된 에어압력이 기준압력(7.8~9bar) 이하일때 콤프레서를 구동시켜 에어압이 보충되도록 한다.The head SCU 1 and the rear SCU 11 are responsible for controlling the overall operation of the high-speed train when the cab is selected as the head power car or the rear power car, and the air pressure sensed by the pressure sensing units 2 and 22. When the pressure is below this reference pressure (7.8-9 bar), the compressor is driven to replenish the air pressure.

이와같이 구성된 하드웨어적 구성에 의해 구현되는 본 발명의 에어콤프레서 제어방법을 설명하면 다음과 같다.Referring to the air compressor control method of the present invention implemented by the hardware configuration configured as described above are as follows.

본 발명의 동작설명은 운전실로서 선두동력차가 선택된 것을 예로하여 설명하기로 한다.The operation description of the present invention will be described by taking an example that the head drive difference is selected as the cab.

운전실이 선택된 선두동력차의 선두SCU(1)는 선두압력감지부(2)에서 감지되는 압력정보로서 선두동력차 또는 후부동력차의 에어압력상태를 감지한다.The head SCU 1 of the head power vehicle in which the cab is selected detects the air pressure of the head power car or the rear power car as the pressure information detected by the head pressure detecting unit 2.

상기 감지결과 에어압력상태가 기준압력 이하라고 판단되면, 선두SCU(1)는 선두메인콤프레서(3)를 구동시킴과 동시에 네트워크로 연결되어 있는 후부동력차의 후부SCU(11)로 메인콤프레서 구동용 제어신호를 전송하고, 상기 후부SCU(11)는 네트워크를 통해 입력되는 제어신호에 따라 후부 동력차의 메인콤프레서(13)를 작동시킨다.If it is determined that the air pressure state is equal to or less than the reference pressure, the head SCU 1 drives the head main compressor 3 and simultaneously controls the main compressor driving to the rear SCU 11 of the rear power car connected by a network. After transmitting the signal, the rear SCU 11 operates the main compressor 13 of the rear power vehicle according to a control signal input through a network.

선두동력차와 후부동력차의 메인콤프레서(3,13) 작동에 의해 에어압력이 기준압력으로 복귀되면 선두SCU(1)는 선두메인콤프레서(3)를 오프시킴과 동시에 네트워크를 통해 후부SCU(11)로 후부메인콤프레서(13) 오프신호를 전송하므로서 선두동력차와 후부동력차의 메인콤프레서(3,13)가 오프된다.When the air pressure returns to the reference pressure by the operation of the main compressors (3, 13) of the head power car and the rear power car, the head SCU (1) turns off the head main compressor (3) and at the same time passes through the network to the rear SCU (11). By transmitting the rear main compressor 13 off signal, the main compressors 3 and 13 of the head power difference and the rear power difference are turned off.

한편, 상기 선두SCU(1)는 초기 에어압이 기준압력 이하라고 판단되었을때 선두메인콤프레서(3)가 작동 차단상태이면 선두보조콤프레서(4)를 구동시켜 에어압이 기준압력으로 충진되도록 한다.On the other hand, the head SCU (1) when the initial air pressure is determined to be less than the reference pressure when the head main compressor (3) is in the operating state to drive the head auxiliary compressor (4) so that the air pressure is filled to the reference pressure.

그리고, 상기 후부SCU(11) 또한 선두SCU(1)로부터 메인콤프레서 작동신호가 네트워크를 통해 전송되었을 때 후부메인콤프레서(13)가 작동 차단상태이면 메인콤프레서(13) 대신 후부 보조콤프레서(14)를 작동시켜 에어압이 기준압력으로 충진되도록 한다.When the rear main compressor 13 is in a shut-off state when the main compressor operation signal is transmitted through the network from the front SCU 1, the rear sub-compressor 14 replaces the rear sub-compressor 14 instead of the main compressor 13. Operate to ensure that the air pressure is filled to the reference pressure.

즉, 후부SCU(11)는 상대편 전동차의 선두 SCU(1)로부터 메인콤프레서 또는 보조콤프레서를 작동시키라는 제어명령이 입력되더라도 해당 콤프레서가 작동 차단상태이면 해당 콤프레서를 작동시키지 않고 작동이 가능한 다른 콤프레서를 작동시켜 에어압을 기준압력으로 상승시키는 것이다.In other words, the rear SCU 11, even if a control command for operating the main compressor or subcompressor is input from the front SCU (1) of the opposing electric vehicle, if the compressor is in the operating state, the other compressor that can be operated without operating the compressor. To increase the air pressure to the reference pressure.

한편, 선두SCU(1)는 콤프레서의 동작중 고속전철의 주행속도가 3Km/h 이하의 속도로 15초 이상 유지되는 경우 또는 동력차 단독운전 조건시 동작중인 콤프레서의 회전속도를 하이 스피드(High speed)가 아닌 하프 스피드(Half speed)로 감속시켜 소비전력이 감쇄되도록 하며, 또한 이러한 콤프레서의 회전속도 감쇄신호를 네트워크를 통해 후부SCU(11)로 전송하여 후부동력차에서 동작중인 콤프레서의 회전속도가 하프 스피드로 감쇄되도록 한다.On the other hand, the head SCU (1) is a high speed (high speed) when the running speed of the high-speed train is maintained for more than 15 seconds at a speed of 3Km / h or less during the operation of the compressor, or when the motor vehicle alone driving conditions The power consumption is reduced by reducing the speed to half speed, and the rotation speed attenuation signal of the compressor is transmitted to the rear SCU 11 through the network so that the rotation speed of the compressor operating in the rear power difference is half speed. To be attenuated.

그리고, 본 발명에서는 고속전철 기동 초기에 판토그래프(Pantograph) 상승 및 VCB 투입에 필요한 압축공기 확보를 위하여 보조 콤프레서를 동작시킨다.In the present invention, the auxiliary compressor is operated in order to secure the compressed air required for pantograph rise and VCB input at the beginning of the high speed train.

즉, 고속전철 기동 초기에 판토그래프의 상승을 위해 판토그래프가 선택되고, 이때의 에어압력이 6.2bar 이하이면 보조콤프레서를 구동시켜 에어압이 충진되도록 하고, 에어압이 7bar 이상으로 상승하게되면 판토그래프의 상승동작이 충분하므로 보조콤프레서를 동작 중지시킨다.In other words, the pantograph is selected for the rise of the pantograph at the beginning of the high-speed train, and if the air pressure is 6.2bar or less, the auxiliary compressor is driven to fill the air pressure. Since the rising motion of the graph is sufficient, the auxiliary compressor is stopped.

이상에서 설명한 바와같이 본 발명은 운전실이 선택된 동력차의 SCU가 콤프레서의 압력상태를 감지하는 단계와, 감지된 압력이 기준압력 이하이면 메인콤프레서 작동을 위한 제어신호를 출력하면서 반대편 동력차로도 메인콤프레서 작동을 위한 제어신호를 출력하는 단계와, 제어신호에 의해 메인콤프레서가 작동하여 압력이 기준압력 이상으로 상승하면 동작중인 콤프레서를 정지시키는 단계로 구성하므로서, 고속전철의 선두동력차 또는 후부동력차에 구비된 메인 및 보조 콤프레서를 효율적으로 작동시켜 고속전철의 에어압이 항상 기준압력을 유지토록 하고, 고속전철의 주행속도가 저속상태일경우 콤프레서의 회전속도를 감소시켜 소비전력이 감소되도록 한 고속전철의 에어콤프레서 제어방법을 제공하는 효과를 기대할 수 있다.As described above, the present invention provides a step in which the SCU of the power vehicle selected by the cab detects the pressure state of the compressor, and when the detected pressure is lower than the reference pressure, the main compressor is operated with the opposite power vehicle while outputting a control signal for operating the main compressor. Outputting a control signal for the main compressor and stopping the compressor in operation when the pressure rises above the reference pressure by the main compressor operating by the control signal. Air compressor of high speed train to maintain the standard pressure at high speed train at all times, and to reduce the power consumption by reducing the rotational speed of the compressor when the high speed train runs at low speed. The effect of providing a control method can be expected.
