Method for generating and sending transponder messages in real time, as well as train control center device and system

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 ...

Problems solved by technology

In actual use, it cannot meet the needs of operation and maintenance;

[0006] When the transponder message pre-storage method is used, due to the limitation of the storage capacity of the train control center, the arbitrary setting of the speed limit starting point, speed limit end point and speed limit value cannot be realized;

[0007] When the balise message is pre-stored, in order to select effective messages, the train control center must adjust according to certain rules when calculating the temporary speed limit starting point and length, thus expanding the actual speed limit area. Affected the operating efficiency of the train
