Embodiment Construction
[0039] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0040] figure 1 It shows a method for calibrating transponder position data in an electronic map provided by Embodiment 1 of the present invention, the method comprising:
[0041] S11. When the train passes the transponder on the track multiple times within a preset time period, the on-vehicle terminal obtains message information sent by the transponder, and obtains identification information of the transponder according to the message information.
[0042] S12. The vehicle-mounted terminal acquires a plurality of position information of the transponder corresponding to the identification information sent by the vehicle-mounted ranging device, and the position information...

The invention provides a calibrating method of transponder position data in an electronic map, a terminal and a control center. When a train passes through transponders on a rail for multiple times within a preset time period, the train-carried terminal acquires identification information of the transponders, and acquires multiple position information of the transponders corresponding to the identification information; the train-carried terminal sends the multiple position information of the transponders to a train control center, and the train control center acquires calibrated position information of the transponders according to the multiple position information of the transponders, and updates initial position information of the corresponding transponders in an initial electronic map according to the calibrated position information and the identification information; the calibrated electronic map is sent to the train-carried terminal, so that the aim of calibrating the transponder positions more accurately is achieved; meanwhile, the position information is automatically acquired when the train runs, so that the manual labor is saved, and larger errors caused by artificial measurement are avoided.
Description
technical field [0001] The invention relates to the technical field of train control, in particular to a method for calibrating position data of a transponder in an electronic map, a vehicle-mounted terminal and a train control center. Background technique [0002] At present, in urban rail transit, the arrangement of transponders is generally one transponder per kilometer according to the regulations, and the position of the transponder will be correspondingly marked on the electronic map. However, due to the constraints of track geology, curves, etc., it is necessary to manually measure and shift to other positions, and eventually the transponder may be placed at a position of 1,100 meters or 990 meters. At this time, the actual position of the transponder does not match the position on the electronic map, and it is necessary to manually calibrate the position data of the transponder and write the position data in the electronic map. [0003] However, if the electronic ma...
