이하, 본 발명의 각부 구성을 구체적으로 설명한다.Hereinafter, the constitution of each part of the present invention will be described in detail.

먼저, 상기 개별운행전력측정수단(100)은 개별 철도차량(1)에 설치되는 것으로 개별 철도차량(1)의 운행전력을 차량단위로 실시간 모니터링한다. 이와 같이 각각의 개별 철도차량(1)에서 측정되는 운행전력은 무선으로 운행전력분석수단(400)에 전송된다.First, the individual driving power measuring means 100 is installed in the individual railway vehicle 1 to monitor the driving power of the individual railway vehicle 1 in real time on a vehicle basis. As such, the driving power measured by each individual railway vehicle 1 is wirelessly transmitted to the driving power analyzing means 400.

이때, 상기 개별운행전력측정수단(100)은 철도차량(1)의 전압 및 전류를 측정하는 전압 및 전류 측정부(110)와, 상기 전압 및 전류 측정부(110)에서 측정된 아날로그 신호 형태의 전압 및 전류값을 디지털 신호 형태의 전압 및 전류값으로 변환하는 A/D변환부(120)와, 상기 A/D변환부(120)를 통해 변환된 전압 및 전류값을 이용해 운행전력을 계산하는 연산처리부(130)와, 상기 연산처리부(130)를 통해 계산된 운행전력을 저장하는 메모리부(140)로 구성된다.In this case, the individual operating power measuring means 100 is a voltage and current measuring unit 110 for measuring the voltage and current of the railway vehicle 1, and the analog signal type measured in the voltage and current measuring unit 110 The A / D converter 120 converts voltage and current values into voltage and current values in the form of digital signals, and calculates driving power using the voltage and current values converted by the A / D converter 120.

이때, 차상의 TCMS(210) 또는 HMI(220)와 지상의 AP(500)간의 데이터 통신은 초고속 무선 통신채널을 이용하여 운행전력을 전송한다.At this time, the data communication between the vehicle TCMS 210 or HMI 220 and the ground AP 500 transmits the driving power using the ultra-high speed wireless communication channel.

그리고 상기 ATO(230)는 상기 TCMS(210)의 하부시스템으로 TCMS(210)에 의해 속도를 제한받을 때에는 자동으로 제동동작을 하며 제한속도 이하가 되면 제동동작을 해제한다. The ATO 230 automatically brakes when the speed is limited by the TCMS 210 to the lower system of the TCMS 210, and releases the braking operation when the speed falls below the speed limit.

이를 위해 상기 운행전력분석수단(400)을 구성하는 피크전력모니터링장치(430)는 우선 개별 철도차량(1)의 운행전력을 분석하여 피크전력을 예측한다.To this end, the peak power monitoring device 430 constituting the driving power analyzing means 400 first predicts the peak power by analyzing the operating power of the individual railway vehicle 1.
