Urban rail transit electronic map sharing method and system

Abstract

The invention discloses an urban rail transit electronic map sharing method and system. The method comprises the steps that a first obtaining request of obtaining electronic map version information of a to-be-operated line is sent to a networked storage server after a VOBC (Vehicle On Board Controller) of a train is turned on; the VOBC receives first version information of electronic map data of the to-be-operated line, sent by the networked storage server according to the first obtaining request; the VOBC sends a second obtaining request of obtaining the electronic map version information of the to-be-operated line to a vehicle on-board storage unit; the VOBC receives second version information of the electronic map data of the to-be-operated line, sent by the vehicle on-board storage unit according to the second obtaining request; the VOBC detects whether the first version information is consistent with the second version information or not; and if the first version information is consistent with the second version information, the VOBC downloads the electronic map data of the to-be-operated line from the vehicle on-board storage unit, and loads the electronic map data of the line after the downloading is finished. According to the method, sharing and online real-time updating functions of the electronic map data are realized.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method and system for sharing an urban rail transit electronic map. Background technique [0002] At present, domestic urban rail transit lines use the electronic map systems of various system integrators. There are problems of different formats and protocols between the electronic map data of each line, and the electronic map data stored on the train's on-board equipment cannot be updated online in real time. [0003] Furthermore, due to the different map formats and protocols between the various lines of urban rail transit, it is difficult to realize the cross-line driving of vehicles between the lines, so that the interconnection of urban rail transit within the region cannot be realized. [0004] In addition, the electronic map data is scattered and stored on each vehicle and ground equipment, which is not convenient for unified maintenance. Contents of the invention [00...
