The Train Autonomous Operation System (TACS) based on vehicle-to-vehicle communication has gradually achieved commercial operation, which has put forward higher requirements for the refinement of the display granularity of the automatic train monitoring system and the simplification of data production.

[0003] The traditional data production method is that the project data production personnel draw the physical equipment and system logical equipment on the trackside one by one according to the results of on-site laser measurement, and adjust the display coordinates according to the specific starting and ending positions of each device's kilometer mark, so that the display areas and positions of different devices are consistent with the on-site equipment and system requirements. When the project site equipment changes or the system data is upgraded, the data production personnel need to readjust the equipment display area and starting and ending positions in the display interface to ensure the accuracy of the station map display in the automatic train monitoring system. This method requires project data production personnel to spend a lot of time drawing and adjusting equipment positions. The data production efficiency is low and cannot meet the refined display requirements of the vehicle-to-vehicle communication system. At the same time, it requires a lot of data verification and testing work, which cannot meet the needs of the rapidly developing rail transit industry.
