Embodiment Construction

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0029] The present invention aims at the limitation of the storage capacity of the train control center in the pre-storage mode of the transponder message in the prior art, so that only one temporary speed limit is allowed to be set within the jurisdiction of a transponder, and the limit cannot be set arbitrarily according to the demand in act...

Abstract

The invention provides a method for generating and sending transponder messages in real time, as well as a train control center device and system. The method comprises the following steps: a central processor of the train control center selects a corresponding target message template according to the received access information; after the temporary speed-limit packet information in the template is changed according to the received speed-limit information, first user data are generated and sent to a decoder, and the decoder generates the transponder messages according to the first user data and sends the transponder messages back to the central processor; and the central processor controls an active transponder through sending the transponder messages to a side tracking electronic unit. According to the method, as well as the train control center device and system provided by the invention, the problem that the messages in the train control center are restricted by storage capacity is solved, the temporary speed-limit order can be given out freely, and the railway transportation efficiency is improved.

Description

technical field [0001] The invention relates to railway communication signal technology, in particular to a method for generating and sending transponder messages in real time, train control center equipment and a system. Background technique [0002] The train control center is an important part of the China Train Control System (CTCS). The train control center sends the train control information used to control the station and the section track circuit to the trackside electronic unit (line side electronic unit, LEU), and then sent to the active transponder through LEU, so as to realize the continuous transmission of train control information. Among them, the information sent by the train control center to the LEU must be in the form of messages. These messages are generated by the channel coding algorithm with the initial user data conforming to certain specifications. The purpose of channel coding the user data is to improve the communication between the transponder and ...
