Abstract
A large number of infrastructure and equipment are distributed along the railway, which will directly affect the safety and efficiency of railway transportation. In this paper, a general monitoring host machine for railway trackside equipment is designed to realize the power supply, automatic networking, logic operation centralized management, data collection, storage and processing of trackside equipment monitoring. The host machine consists of a CPU board, a interface board, a power board, several PLC (Power Line Carrier) communication boards and isolation transformers. It supports a variety of monitoring applications, and covers almost all monitoring requirements of trackside equipment. Based on the monitoring host machine, a monitoring system for trackside equipment of track circuit system is developed.
