Fault analysis of railway signal equipment based on Microcomputer Monitoring
Abstract: Computer monitoring is called the railway department of the black box, the effective use of computer monitoring system of railway department, is an important means to improve maintenance quality, reduce equipment fault signal signal. In this paper, the structure and the interface circuit of the microcomputer monitoring system of TWJX-2006 version are analyzed, and the objects under normal working condition are analyzed. And through the signal concentration monitoring system switch amount and analog record curve, the quality of signal equipment or the hidden trouble of signal equipment are analyzed. Among them, the basic equipments of railway signals include ZD6 type switch machine, single moving or multiple switch, S700K speed increasing switch and 25Hz track circuit. Through microcomputer monitoring, the parameters of these signal devices can be monitored in real time. When abnormal situation occurs, the fault point can be quickly judged and analyzed. Combined with its own understanding of the electrical characteristics of the signal equipment and mechanical characteristics, and quickly deal with the failure or eliminate possible hidden dangers.
