Abstract

The embodiment of the invention provides a method and a device for checking the positions of ground transponders in a rail transit. The method comprises the following steps: obtaining the actual distance between any two adjacent transponders through which a train passes in a line according to a speed sensor on the train; obtaining a theoretical distance between the two adjacent transponders according to the preset installation positions of the two adjacent transponders; and calculating a difference value between the actual distance and the theoretical distance between the two adjacent transponders, and taking the difference value as an installation error of the two adjacent transponders. According to the embodiment of the invention, the method and the device achieve the automatic checkingof the positions of the transponders, improve the checking efficiency of the positions of the transponders, are not affected by manual factors, and are more accurate in checking result.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a method and device for checking the position of a ground transponder in rail transit. Background technique [0002] With the development of urban rail transit, the signaling system based on CBTC (Communication Based Train Control) system and FAO (Fully Automatic Operation) system has gradually become the mainstream of urban rail transit signaling system. As an important positioning device in the CBTC system and the FAO system, the transponder plays a key role in the safety of train operation, so it is necessary to ensure that the installation position of the transponder is accurate. [0003] At present, the installation position of the transponder is checked through manual measurement and re-testing to determine whether the installation position of the transponder meets the preset installation requirements. When it is detected that the installation position of the transpon...
