Title:
SAFETY CODING METHOD FOR TRACKSIDE TRAIN POSITIONING INFORMATION
Document Type and Number:
WIPO Patent Application WO/2024/045337
Kind Code:
A1
Abstract:
A safety coding method for trackside train positioning information, comprising the following steps: by means of a redundancy coding scheme, compiling line position coded information of a train to form a position coded string (S1); printing the compiled position coded string comprising the line position coded information to obtain an identification board, and mounting same on a trackside tie (S2); mounting an image collector on the body of the train, the image collector collecting the coded string on the identification board, performing preliminary check on the coded string, and after the check is passed, sending the identified coded string to a vehicle-mounted safety computer (S3); the vehicle-mounted safety computer receiving the coded string sent by the image collector, and, after performing multi-channel redundancy safety computation on the coded string, looking up tables in a position database to obtain the train position information corresponding to the coded string (S4); and, according to the train position information determined by means of the table look-up, updating the real position of the train (S5). The beneficial effects are that: multiple means such as redundancy computation and conversion check computation are used, thus improving the safety of position computation, overcoming the defects of visual identification in reliability and safety, and improving the positioning accuracy of performing passive train positioning on the basis of trackside devices by using image collection techniques.
