Abstract
A track circuit electrical characteristic monitoring system comprises a steel rail and a track circuit used for transmitting information between a track and a main machine; the monitoring system also comprises m*n monitoring branch machines connected with the main machine by m pairs of solid loops; each monitoring branch machine is identical in structure and mainly consists of a processing unit, a current sampling unit, a track surface voltage sampling unit, a current-limiting resistance and voltage sampling unit, a communication module and a power supply changeover module; the main machine is responsible for managing the monitoring branch machines, establishing communication links with the branch machines in a polling mode for data communication, analyzing and processing the received monitoring information and data, displaying the information and data in figures and curves, and giving an alarm when the parameters are beyond the limits. According to the track circuit electrical characteristic monitoring system, the main machine is connected with the m*n branch machines hooked with the m pairs of solid loops, the real-time monitoring on the electrical characteristics of the track circuit is realized, the system structure is simple, the design is scientific, safety and reliability are achieved, the investment is saved, the efficiency is high, and further, the railway transportation efficiency can be improved, and the traffic safety is ensured.
Description
technical field [0001] The invention relates to the field of electrical monitoring of railway track circuits, in particular to a system for monitoring electrical characteristics of track circuits. Background technique [0002] The circuit composed of the rails of the railway line as a conductor to check whether there are trains, transmit train occupancy information, and realize the transmission of information between the ground and the train is called a track circuit. In the daily maintenance of railway signals, the detection and adjustment of the electrical characteristics of the track circuit to ensure the normal operation of the track circuit is the basic condition for ensuring traffic safety and maintaining traffic order. At present, the monitoring of the electrical characteristics of the track circuit is only carried out indirectly in the mechanical room, and the detection of the actual state of the outdoor field can only be carried out manually. The existing problems ...
