Frequency-shifting track circuit integrated monitoring system based on high-speed electric power carrier communication

Abstract

The invention provides a frequency-shifting track circuit integrated monitoring system based on the high-speed electric power carrier communication. A to-be-measured orbit section comprises a plurality of tunable regions. Each tunable region is composed of a sending tuner unit of each orbit section, a hollow coil, and a receiving tuner unit of the next adjacent or power carrier communication module; bit section. Each sending / receiving tuner unit is composed of a monitoring unit extension set and the monitoring unit extension set comprises an acquisition monitoring module and a high-speed power carrier communication module, wherein the acquisition monitoring module and the high-speed power carrier communication module are sequentially connected together. The monitoring unit extension set of each sending / receiving tuner unit transmits the sampled data of each to-be-measured object in real time to a centralized management machine via the high-speed power carrier communication module. The centralized management machine is respectively connected with a signal centralized monitoring system and an operation terminal. According to the system, the current flowing through each ladle copper wire of matched tuner units is sampled in real time. In this way, the mounting reliability of the ladle copper wire is detected. By means of the system, faults, such as the poor contact of the ladle copper wire and even the broken condition of the ladle copper wire, can be found out timely.

Description

technical field [0001] The invention relates to the technical field of railway monitoring equipment, in particular to a high-speed power carrier communication and track circuit comprehensive monitoring system. Background technique [0002] Frequency-shifting track circuit is an important part of railway signaling equipment, and it is also one of the key equipment that affects the safety of railway transportation. Due to the large number and wide distribution of outdoor equipment on frequency-shifting track circuits, and they are far away from the signal work area, it takes a lot of time to inspect and inspect them on the road. Once equipment failure occurs, the processing time is often relatively long, resulting in a long delay long, which has a great impact on transportation efficiency. [0003] Most of the data communication methods of the frequency-shifting track circuit outdoor monitoring systems that have been used on the road at present use RS485 data bus or CAN data ...

AI Technical Summary

Problems solved by technology

If the solution of re-laying cables is adopted, the construction cost will be greatly increased, which is not conducive to the promotion of the system

Even if there is no shortage of spare cables, the maximum communication rate of RS485 data bus and CAN data bus in this kind of long-distance communication application does not exceed 9600bps, and the low data throughput of the system makes the real-time performance of system data low.

Under the current trend of gradually promoting intelligent diagnosis, too little data cannot make the system unable to accurately diagnose the working status of the frequency shifting track circuit
