ZPW2000 section track outdoor signal monitoring system

Abstract

The invention provides an ZPW2000 section track outdoor signal monitoring system which comprises a monitoring communication processor, a PLC (programmable logic control) communication extension set and acquisition extension sets. The acquisition extension sets comprise acquisition protection boxes arranged beside monitoring tracks; tuning matching units, acquisition units, acquisition fixing clipsand acquisition wiring terminals are arranged in the acquisition protection boxes, and wiring connecting frames, sensors and steel rail lead wires are arranged outside the acquisition protection boxes; the steel rail lead wires are connected with the monitoring tacks and the wiring connecting frames; the tuning matching units are provided with cables, the PLC communication extension unit comprises a plurality of PLC modules, and the PLC modules comprise isolated power supplies, wave trappers and PLC communication boards; the monitoring communication processor comprises processing hosts, an MCU (microprogrammed control unit) motherboard with built-in single chip microcomputers, a motherboard power supply and CAN (controller area network) bus; the PLC communication boards are in data communication with the sensors, data can be transmitted to the MCU motherboard by the PLC communication boards, and the data transmitted by the PLC communication boards can be transmitted to the processinghosts by the MCU motherboard via the CAN bus in real time, so that real-time monitoring can be carried out.

Description

technical field [0001] The invention relates to the field of railway signal monitoring, in particular to a ZPW2000 outdoor signal monitoring system for interval tracks. Background technique [0002] my country is a big railway country. After introducing the French UM71 frequency-shifting track circuit in the early 1990s, it began to develop its own ZPW-2000 series non-insulated frequency-shifting track circuit that is more suitable for my country's railways in combination with my country's national conditions. At present, my country's railway signal microcomputer monitoring system has been widely used in the ZPW-2000 series non-insulated frequency-shifting track circuit. The real-time collection and analysis provided an important technical means and basis for electrical maintenance personnel to grasp the equipment operation status, fault handling and fault analysis, and achieved certain results. However, the existing railway signal monitoring system mainly monitors indoor si...

AI Technical Summary

Problems solved by technology

However, the existing railway signal monitoring system mainly monitors indoor signal equipment, and lacks comprehensive automatic real-time monitoring of outdoor signal equipment, especially interval track equipment. Outdoor signals have certain interference and influence of human factors, and there is a certain degree of security. Hidden danger
