Abstract
Train operation control system is the core of urban rail transit system, and the train carborne control system is an important part of the whole train operation control systems, and its reliability will directly affect the safety of the train. In this paper, two out of three closed-loop dynamic input detection technology and hardware dynamic two out of two voting output technology and time synchronization technology were used to design relay node status acquisition and control scheme of the train carborne control system respectively, and effectively guaranteed the reliability of relay node status acquisition and control of the train carborne control system and therefore ensure the safety of operation of the train.
Highlights
The basic task of urban rail transit is transporting passengers in a safety, punctuality, high efficiency and high density way
With the rapid development of Chinese economy and the acceleration of urbanization, urban rail transit has entered a period of rapid development1
Train carborne control system is one of the core of urban rail transit system, which plays an important role in improving the operational efficiency of rail transit and ensuring the safety of train operation [1, 2].The train carborne control system is the core of the train operation control system, and the guarantee of the normal operation of the transportation system [3].It is connected with some equipment or system such as the train, traction, line and rail
Summary
The basic task of urban rail transit is transporting passengers in a safety, punctuality, high efficiency and high density way. Train carborne control system is one of the core of urban rail transit system, which plays an important role in improving the operational efficiency of rail transit and ensuring the safety of train operation [1, 2].The train carborne control system is the core of the train operation control system, and the guarantee of the normal operation of the transportation system [3].It is connected with some equipment or system such as the train, traction, line and rail. The train carborne control system of relay node state acquisition and control scheme can effectively guarantee the reliability of the system to the data acquisition and control of the external device relay node working state, and effectively ensure safe operation of train carborne control system
