Description

Rail transit multi-device status fusion display processing method, equipment and medium Technical Field

[0001] The present invention relates to a train signal control system, and in particular to a method, device and medium for fusion display processing of multiple equipment states in rail transit. Background Art

[0002] At present, urban rail transit has initially achieved networked operation, with a surge in passenger traffic and an increased demand for transport capacity on backbone lines in urban core areas. The Train Autonomous Operation System (TACS) based on vehicle-to-vehicle communication has gradually achieved commercial operation, placing higher demands on the refinement of the display granularity of the automatic train monitoring system and the simplification of data production.

[0003] Traditionally, project data production personnel mapped each physical trackside device and system logical device based on on-site laser survey results. They then adjusted the display coordinates based on the specific starting and ending locations of each device's kilometer markers to ensure that the display areas and positions of each device aligned with the on-site device and system requirements. Whenever on-site project equipment changed or system data was upgraded, data production personnel needed to readjust the device display areas and start and end locations within the interface to ensure the accuracy of the station map displayed within the automatic train monitoring system. This method required project data production personnel to spend a significant amount of time drawing and adjusting device positions, resulting in low data production efficiency and failure to meet the refined display requirements of the train-to-train communication system. Furthermore, it required extensive data verification and testing, making it unsuitable for the rapidly evolving needs of the rail transit industry.

[0004] After searching, Chinese patent publication number CN116101341A discloses a device and method for displaying vehicle information, which specifically discloses: an ATP module for sending signal equipment operating status information to an on-board communication board; an ATO module for sending train control information to an on-board communication board; an on-board communication board for sending received information to a TRDP board; a TRDP board for sending received information to a display module, and displaying signal equipment operating status information and train control information based on the display module. However, this existing patent does not involve the fusion of multiple device states in the main device state. Therefore, how to fuse the multiple device states into the same basic map to reduce the workload of data production has become a technical problem that needs to be solved.
