Method and device for rewriting transponder message

Abstract

The embodiment of the invention provides a method for rewriting a transponder message. The method comprises the following steps of: receiving a first transponder message which is to be written into a transponder to be rewritten; reading a first key variable in the first transponder message; reading a second key variable in a second transponder message which exists in the responder to be rewritten; and comparing that whether the first key variable with the second key variable are consistent or not, if yes, writing the first transponder message into the responder to be rewritten. According to the method, a step of monitoring the transponder message writing is additionally arranged, so that the transponder message can be effectively prevented from being written into the non-corresponding transponder, moreover, the checking and rewriting work of the transponder message is completed through a computer, the engineering technicians are not needed, thus, the possible risk that the engineering technicians do not write the transponder message into the corresponding transponder can be reduced, and the accuracy of on-site transponder message rewriting is ensured. In addition, the embodiment of the invention further provides a device for rewriting the transponder message.

Description

technical field [0001] The invention relates to the technical field of railway signals, and more specifically relates to a transponder message rewriting method and device. Background technique [0002] The balise (Balise) is a point-type device used for ground-to-train information transmission, and its main purpose is to provide reliable ground information to the train control vehicle equipment. Each transponder (or group of transponders) has a number which is unique railway-wide across the country. The balise is installed at the entrance of the block partition or at the entrance and exit of the station. When the train passes the balise, the balise sends the balise message stored by itself or the balise message transmitted by the ground electronic unit (LEU) to the train control vehicle. The device provides information such as train positioning, line slope, speed, etc. [0003] As the reading and writing test equipment of the transponder message, the transponder rewriting ...

Problems solved by technology

[0006] In view of this, in order to solve the problem in the prior art that the transponder message read by the transponder caused by artificially checking and changing the transponder message is inaccurate, on the one hand, a transponder message rewriting method is provided, The technical solution is as follows:
