Monitoring system for railway outdoor trackside signal equipment

Abstract

The invention discloses a monitoring system for railway outdoor trackside signal equipment. The outdoor railway trackside signal equipment comprises a ZPW-2000 A / K track circuit, a 25 Hz phase-sensitive track circuit, a train annunciator and a point switch. The monitoring system comprises a power supply, an outdoor trackside signal equipment collector, a PLC protocol converter, a communication interface extension set and a centralized monitoring station machine. The power supply is connected with the outdoor trackside signal equipment collector, the outdoor trackside signal equipment collector is connected with the ZPW-2000 A / K track circuit, the 25 Hz phase-sensitive track circuit, the train annunciator and the point switch, and the outdoor trackside signal equipment collector, the PLC protocol converter, the communication interface extension set and the centralized monitoring station machine are connected in sequence. Compared with the prior art, the monitoring system has the advantages that equipment fault points are accurately and rapidly judged, and fault handling time is greatly shortened.

Description

technical field [0001] The invention relates to a monitoring system for railway equipment, in particular to a monitoring system for railway outdoor trackside signal equipment. Background technique [0002] At present, the domestic signal centralized monitoring system collects information on various equipment only in indoor local circuits, and 90% of signal equipment failures occur outdoors. When a failure occurs, maintenance personnel can only measure manually because there is no means of monitoring outdoor equipment. , Find the fault point, the fault processing time is longer. In particular, the fault processing time of the section track circuit is longer, often exceeding 2 hours, which constitutes a D21 accident and seriously interferes with the traffic organization. Contents of the invention [0003] The object of the present invention is to provide a monitoring system for railway outdoor trackside signal equipment in order to overcome the above-mentioned defects in th...
