Turnout state monitoring method based on turnout indication module and encoding circuit

Abstract

The invention relates to a turnout state monitoring method based on a turnout indication module and an encoding circuit. The main reason for railway turnout accidents is inconformity in indoor turnout indication and outdoor turnout indication, and the inconformity in indications is mainly caused by complexity in turnout indication circuits and error maintenance after breakdown. An outdoor turnout indication module collects turnout indication information, specific identification codes are added on the information and encoded through the encoding circuit, encoded data is transmitted to an indoor turnout indication module, and a decoding circuit decodes the encoded data and transmits the decoded data to a computer interlocking system and a microcomputer monitoring system. Turnout indication circuits are modularized, and an inserting-connection design is adopted, so that the turnout indication modules are simple in installation, easy to maintain and capable of being replaced and installed integrally and reducing maintenance times and time. The specific identification codes are added on the turnout indication information through the encoding circuit to perform data encoding transmission, so that inconformity in indoor turnout indication and outdoor turnout indication caused by wire mixing is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of railway electrical equipment, and in particular relates to a switch state monitoring method based on a switch display module and an encoding circuit. Background technique [0002] Through the analysis of the major safety accidents of railway traffic over the years, it can be known that the main reason for the turnout accidents is the inconsistency between the indoor and outdoor turnout indications, which is mainly attributed to the complexity of the turnout indication circuit, and the maintenance of signal maintenance personnel after the turnout indication circuit fails. error repair. The occurrence of these accidents may cause the train to fail to run on time, or cause the train to derail and roll over, causing significant loss of personnel and property. [0003] Although various commonly used switch machines have corresponding stereotyped circuits, and have been popularized and applied on a large...

Problems solved by technology

However, from the point of view of actual use, these stereotypes indicate that there are some deficiencies and weak links in the circuit, and these weak links have become prone to failures, such as protection resistors and rectifiers are easy to burn out, cables mixed lines, wiring errors, etc. cause turnouts No indication, wrong indication, on-site maintenance personnel blindly reverse the direction of the half-wave rectifier when repairing the fault, resulting in inconsistent indications of indoor and outdoor switches, etc.
