In addition, the present invention relates to a current communication device for automatic control of a high-speed railway, which enables current communication in response to the communication speed being controlled in the MPU.

통신하는 주된 방법으로는 전압데이타 통신방식으로서 MPU와 고속철도장비 상호간의 데이타 통신을 전압데이타로서 송수신하는 것이다.The main method of communication is the voltage data communication method, which transmits and receives data communication between the MPU and high-speed railway equipment as voltage data.

그러나, 종래의 전압데이타 송수신방법은 고속철도 내의 노이즈 및 진동등에 의해 안정적인 데이타의 교환이 이루어지지 않게 되어 MPU와 고속철도장비 상호간의 실시간 고속통신이 이루어지지 않게되고, 이로인해 MPU의 자동제어가 원만하게 이루어지지 않게되는 문제점이 발생하고 있었다.However, in the conventional voltage data transmission / reception method, stable data is not exchanged due to noise and vibration in the high-speed railway, so that real-time high-speed communication between the MPU and the high-speed railway equipment is not achieved, and thus, automatic control of the MPU is performed smoothly. There was a problem of not being supported.

In addition, the present invention aims to provide a current communication device for automatic control of a high-speed railway that enables current communication in response to the communication speed in the MPU.

이와같이 구성된 본 발명의 동작을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above is as follows.

먼저, MPU(2)에서 소정의 전압데이타가 출력되면, 그 전압데이타는 직렬통신부(4)를 통해 전류데이타 변환수단(3)의 송신데이타변환부(5)로 공급되고, 상기 송신데이타변환부(5)는 입력되는 전압데이타를 전류데이타로서 변환하여 고속철도장비(1)로 전송한다.First, when predetermined voltage data is output from the MPU 2, the voltage data is supplied to the transmission data conversion section 5 of the current data conversion means 3 through the serial communication section 4, and the transmission data conversion section. (5) converts the input voltage data as current data and transmits it to the high speed railway equipment (1).

이때, 상기 송신데이타변환부(5)의 출력단에 설치되어 있는 전류제한부(8)는 송신되는 전류데이타가 4~20mA의 적정한 범위를 유지할 수 있도록 전류데이타의 전류값의 상하한선을 제한하며, 노이즈필터(7)는 송신되는 전류데이타의 노이즈를 제거하여 고속철도장비(1)로 송신하게된다.At this time, the current limiting section 8 provided at the output terminal of the transmission data converting section 5 limits the upper and lower limits of the current value of the current data so that the current data to be transmitted can maintain an appropriate range of 4-20 mA, and noise The filter 7 removes the noise of the transmitted current data and transmits it to the high speed railway equipment 1.
