본 발명은 고속전철의 에어콘 기능 제어방법에 관한 것으로서, 특히 고속전철 주행중 객차에 설치된 에어콘의 동작을 보다 정밀하게 제어할 수 있고, 또한 고속전철의 사구간으로 진입하였을때에도 에어콘이 정지하도록 하여 에어콘의 동작제어에 대한 신뢰도가 한층 더 향상되도록 한 고속전철의 에어콘 기능 제어방법에 관한 것이다.The present invention relates to a method for controlling the air conditioner function of a high-speed train, and more particularly, to more precisely control the operation of an air conditioner installed in a passenger car while driving a high-speed train, and to stop the air conditioner even when entering a four-sector section of the high-speed train. The present invention relates to a method for controlling air conditioner function of a high-speed train so that the reliability of motion control is further improved.

현재 국내에는 시속 350Km/h 이상의 속도로 고속주행하는 고속전철이 운행되고 있다.At present, high speed trains are operating in Korea at high speeds of over 350 km / h.

이러한 고속전철은 차량을 견인하는 동력차와 승객들이 탑승하는 객차로 이루어져 있으며, 동력차에 탑재되는 SCU가 고속전철의 주행 및 여러가지 안전장치들을 총괄하여 제공하도록 구성된다.The high-speed train is composed of a power vehicle towing a vehicle and a passenger vehicle on which passengers board, and the SCU mounted on the power vehicle is configured to collectively provide driving and various safety devices of the high-speed train.

고속전철에는 실내온도조절을 위한 에어콘이 설치되어있고, 에어콘을 온/오프 제어하는 에어콘 콘트롤유닛이 객차에 설치된다.The high-speed train is equipped with an air conditioner for controlling room temperature, and an air conditioner control unit for controlling the air conditioner on / off is installed in the passenger car.

그러나, 종래의 에어콘 제어방법은 대부분이 운전자 또는 승무원의 스위치 조작에 의존하여 에어콘을 온/오프 제어하도록 구성되어 있기 때문에 고속전철의 운전조건에 신속히 대응하여 에어콘을 보다 정밀하게 온/오프 제어할 수 없었고, 고속전철이 사구간을 통과할때에는 에어컨이 일시적으로 정지되어야만 하나 운전자 또는 승무원의 실수에 의해 에어컨이 정상작동하게되는 문제점이 발생하고 있었다.However, since the conventional air conditioner control method is configured to control the air conditioner on / off depending on the switch operation of the driver or the crew, the air conditioner can be controlled on / off more precisely in response to the operating conditions of the high speed train. There was no problem that the air conditioner had to be temporarily stopped when the high-speed train passed the four-way section, but the air conditioner was operating normally due to a mistake of the driver or the crew.

따라서, 상기 문제점을 해결하기 위한 본 발명은 에어콘 온신호 인가조건에서 440VAC 정상신호가 입력되면 동력차의 SCU가 네트워크신호를 통해 객차의 에어콘 콘트롤유닛으로 에어콘 동작명령신호를 전송하는 제 1 단계와; 제 1 단계 이후 에어콘 온신호가 차단되거나 440VAC 정상신호가 차단되면 SCU가 네트워크신호를 통해 에어콘 콘트롤유닛으로 에어콘 정지명령신호를 전송하는 제 2 단계로 구성하므로서, 고속전철 주행중 객차에 설치된 에어콘의 동작을 보다 정밀하게 제어할 수 있고, 또한 고속전철의 사구간으로 진입하였을때에도 에어콘이 정지하도록 하여 에어콘의 동작제어에 대한 신뢰도가 한층 더 향상되도록 한 고속전철의 에어콘 기능 제어방법을 제공함을 목적으로 한다.Accordingly, the present invention for solving the above problems is a first step of transmitting the air conditioning operation command signal to the air conditioning control unit of the passenger car via the network signal when the 440VAC normal signal is input in the air conditioning on signal application condition; If the air conditioner on signal is blocked after the first step or the 440VAC normal signal is blocked, the SCU is configured as a second step of transmitting the air conditioner stop command signal to the air conditioner control unit through the network signal, thereby operating the air conditioner installed in the passenger car while driving on the high-speed train. It is an object of the present invention to provide a method for controlling the air conditioner function of a high speed train, which can be more precisely controlled and also allows the air conditioner to stop even when entering the four-lane section of the high speed train so that the reliability of the operation control of the air conditioner can be further improved.

이하, 첨부된 도면 도 1 과 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 하드웨어적 구성을 도시한 것으로서,1 illustrates a hardware configuration for implementing the present invention.

고속전철은 동력차와 객차로 대별 구성되고,High-speed trains are composed of power cars and passenger cars.

상기 동력차에는 동력차의 전반적인 동작을 제어하면서 에어콘 온신호가 인가된 조건하에서 440VAC 정상신호가 입력되었을때 네트워크신호를 이용하여 객차의 에어콘 콘트롤유닛으로 에어콘 동작명령신호를 전송하고, 이후 에어콘 온신호 차단 또는 440VAC 정상신호가 차단되었을때 네트워크신호를 이용하여 에어콘 콘트롤유닛으로 에어콘 정지명령신호를 전송하는 SCU(Supervisory Control Unit, 중앙제어처리장치)(1)가 구성되어 있다.When the 440VAC normal signal is input to the power vehicle under the condition that the air conditioner on signal is applied while controlling the overall operation of the power vehicle, the air conditioner operation command signal is transmitted to the air conditioner control unit of the passenger car using a network signal, and then the air conditioner on signal is blocked or The SCU (Supervisory Control Unit) 1 is configured to transmit the air conditioner stop command signal to the air conditioner control unit by using a network signal when the 440VAC normal signal is cut off.

상기 객차에는 네트워크신호를 통해 SCU(1)로 부터 에어콘 동작명령 또는 정지명령을 입력받고, 그 입력된 에어콘 관련 제어신호를 에어콘 콘트롤유닛(3)으로 공급하는 VCU(Vehicle Contorl Unit, 차량제어장치)(2)와;The vehicle receives an air conditioner operation command or a stop command from the SCU 1 through a network signal, and supplies a control signal related to the air conditioner to the air conditioner control unit 3 (VCU (Vehicle Control Unit)). (2);

상기 VCU(2)로부터 공급되는 에어콘 동작명령신호 또는 에어콘 정지명령신호에 따라 객차의 에어콘을 온/오프 구동하는 에어콘 콘트롤유닛(3)과;An air conditioner control unit (3) for driving on / off the air conditioner of the passenger car according to the air conditioner operation command signal or the air conditioner stop command signal supplied from the VCU (2);

무정전 기능을 가지면서 정전압 정주파 전원 제어기능을 갖는 CVCF(Constant Voltage Constant Frequency, 인버터) 콘트롤유닛(4)이 구성되어 있다.A CVCF (Constant Voltage Constant Frequency, Inverter) control unit 4 having an uninterruptible function and having a constant voltage constant frequency power supply control function is configured.

그리고, 상기 SCU(1)는 고속전철 주행중 ATC(Automatic Ttain Control, 열차자동제어장치)로부터 궤도회로의 일부분에 고속전철이 점유하여도 궤도계전기가 작동되지 않는 구간을 의미하는 사구간 진입신호가 인가되었을때 에어콘 정지명령신호를 네트워크를 통해 에어콘 콘트롤유닛(3)으로 공급하고, ATC로 부터 사구간을 벗어났음을 알려주는 사구간 통과신호가 인가되면 다시 에어콘 콘트롤유닛(3)으로 에어콘 동작명령신호를 출력한다.In addition, the SCU (1) is applied to the four-lane entry signal signifying the section in which the track relay does not operate even if the high-speed train occupies a portion of the track circuit from the ATC (Automatic Ttain Control) during high-speed train driving When the air conditioner stop command signal is supplied to the air conditioner control unit (3) through the network, and when the four-segment pass signal indicating that the four-way out of the four sections from the ATC is applied, the air conditioner operation command signal to the air conditioner control unit (3) again. Outputs

이와같이 구성된 본 발명의 동작을 도 2를 참조하여 설명하면 다음과 같다.The operation of the present invention configured as described above will be described with reference to FIG. 2.

먼저, 고속전철이 주행중일때 에어콘 온신호 인가조건에서 440VAC 정상신호(440V AC 전압이 정상적으로 인가되고 있음을 감지한 신호)가 인가되면, 동력차의 SCU(1)는 객차의 에어콘이 정상동작할 수 있도록 에어콘 동작명령신호를 네트워크를 통해 객차의 VCU(2)로 전송하고, 상기 VCU(2)는 에어콘 동작명령신호를 에어콘 구동용 에어콘 콘트롤유닛(3)으로 공급한다.First, if a 440 VAC steady signal (a signal that detects that the 440 V AC voltage is normally applied) is applied under the air conditioner on-signal application condition while the high-speed train is driving, the SCU 1 of the power vehicle may enable the air conditioner of the passenger car to operate normally. The air conditioner command signal is transmitted to the VCU 2 of the passenger car through a network, and the VCU 2 supplies the air conditioner command signal to the air conditioner control unit 3 for driving the air conditioner.

이에따라, 상기 에어콘 콘트롤유닛(3)이 SCU(1)에서 전송된 에어콘 동작명령신호에 따라 에어콘을 구동시키므로서, 객차의 에어콘이 정상적으로 작동하게 되는 것이다.Accordingly, the air conditioning control unit 3 drives the air conditioner according to the air conditioner operation command signal transmitted from the SCU 1, so that the air conditioner of the passenger car is normally operated.

한편, 에어콘 구동중에 에어콘 온신호 차단 또는 440VAC 정상신호가 차단되면, SCU(1)는 에어콘 오프동작을 위한 에어콘 정지명령신호를 네트워크를 통해 객차의 VCU(2)로 공급하고, 상기 VCU(2)는 수신한 에어콘 정지명령신호를 에어콘 콘트롤유닛(3)으로 공급함에 따라 객차의 에어콘이 정지하게된다.On the other hand, when the air conditioner on signal blocking or the 440VAC normal signal is blocked while driving the air conditioner, the SCU (1) supplies the air conditioner stop command signal for the air conditioner off operation to the VCU (2) of the vehicle through the network, the VCU (2) The air conditioner of the passenger car is stopped by supplying the received air conditioner stop command signal to the air conditioner control unit 3.

또한 본 발명에서는 객차에 탑재된 에어콘을 고속전철의 사구간 진입 여부에 따라 온/오프 제어한다.In addition, according to the present invention, the air conditioner mounted on the passenger car is controlled on / off according to whether the high-speed train enters the four sections.

즉, 고속전철이 사구간에 진입하게 되면, ATC 장치로부터 SCU(1)에 사구간진입신호가 공급되고, 상기 SCU(1)는 사구간 진입에 따라 객차의 에어콘을 정지시키기 위한 에어콘 정지명령을 네트워크를 통해 에어콘 콘트롤유닛(3)으로 전송하므로서, 사구간 진입시 객차의 에어콘이 정지하게되며,That is, when the high-speed train enters the four-lane section, a four-lane entry signal is supplied from the ATC device to the SCU 1, and the SCU 1 issues an air conditioner stop command for stopping the air conditioner of the passenger car as the entry into the four-lane section. By transmitting to the air conditioning control unit (3) through, the air conditioner of the carriage stops when entering the four-segment,

고속전철이 사구간을 통과하여 ATC장치로부터 SCU(1)에 사구간 통과신호가 공급되면, 상기 SCU(1)는 에어콘을 작동시키기 위한 에어콘 동작명령신호를 네트워크를 통해 에어콘 콘트롤유닛(3)으로 전공하고, 에어콘 콘트롤유닛(3)은 SCU(1)에서 전송된 에어콘 동작명령신호에 따라서 객차의 에어콘을 작동시키는 것이다.When the high-speed train passes through the four-lane section and the four-lane section passing signal is supplied from the ATC device to the SCU 1, the SCU 1 sends an air-conditioning operation command signal for operating the air-conditioner to the air-conditioning control unit 3 through the network. The air conditioner control unit 3 operates the air conditioner of the passenger car according to the air conditioner operation command signal transmitted from the SCU 1.

상기 설명과 같이 본 발명은 에어콘 온/오프 신호 및 440VAC의 정상입력여부에 따라 객차에 탑재된 에어콘을 정밀하게 제어할 수 있게 되는 것이고,As described above, according to the present invention, the air conditioner mounted on the vehicle can be precisely controlled according to the air conditioner on / off signal and normal input of 440 VAC.

또한, 고속전철의 사구간 진입여부에 따라 객차의 에어콘을 제어하는 것이다.In addition, the air conditioner of the passenger car is controlled according to whether or not the high-speed rail is entered into the four sections.

한편, 본 발명에서는 에어콘 콘트롤유닛(3)으로부터 에어콘 배기기능 고장신호가 약 20초 이상 지속되면, 인버터(Inverter) 고장이 검지되지 않은 조건에서 CVCF 콘트롤유닛(4)으로 냉각고장신호를 출력하며,On the other hand, in the present invention, if the air conditioner exhaust function failure signal from the air conditioner control unit 3 lasts about 20 seconds or more, the cooling fault signal is output to the CVCF control unit 4 under the condition that the inverter fault is not detected,

또한, CVCF 인버터 고장신호 인가시에는 냉각팬 제어를 위하여 에어콘 콘트롤 유닛으로 CVCF 인버터 고장신호를 출력하게 한다.When the CVCF inverter fault signal is applied, the CVCF inverter fault signal is output to the air conditioner control unit for cooling fan control.

이상에서 설명한 바와같이 본 발명은 에어콘 온신호 인가조건에서 440VAC 정상신호가 입력되면 동력차의 SCU가 네트워크신호를 통해 객차의 에어콘 콘트롤유닛으로 에어콘 동작명령신호를 전송하는 제 1 단계와; 제 1 단계 이후 에어콘 온신호가 차단되거나 440VAC 정상신호가 차단되면 SCU가 네트워크신호를 통해 에어콘 콘트롤유닛으로 에어콘 정지명령신호를 전송하는 제 2 단계로 구성하므로서, 고속 전철 주행중 객차에 설치된 에어콘의 동작을 보다 정밀하게 제어할 수 있고, 또한 고속전철의 사구간으로 진입하였을때에도 에어콘이 정지하도록 하여 에어콘의 동작제어에 대한 신뢰도가 한층 더 향상되도록 한 고속전철의 에어콘 기능 제어방법을 제공하는 효과를 기대할 수 있다.As described above, the present invention provides a first step of transmitting an air conditioner operation command signal to an air conditioner control unit of a passenger car through a network signal when a 440VAC normal signal is input in an air conditioner on signal application condition; When the air conditioner on signal is blocked after the first step or the 440VAC normal signal is blocked, the SCU is configured as a second step of transmitting the air conditioner stop command signal to the air conditioner control unit through the network signal, thereby operating the air conditioner installed in the passenger car during the high-speed train driving. The effect of providing a method of controlling the air conditioner function of the high-speed train, which can control more precisely and also allow the air conditioner to stop even when entering the four-lane section of the high-speed train, further improves the reliability of the air conditioner operation control. have.
