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.
