Method, device and system for processing train control message

Abstract

The embodiment of the invention discloses a method, a device and a system for processing a train control message. The method comprises the following steps of: framing user data in real time and coding the framed user data; and verifying the correctness of the coding by using the inverse operation decoding of the coding, wherein if the decoding is reversible, the coding is correct; if the decoding is not reversible, the coding is wrong; and packaging the coded messages which are verified correct and transmitting the messages to ground electronic equipment. A message processing flow of framing in real time, coding, verifying and sending the user data transmitted by a bus is formed. On the basis of the European railway transportation management system coding standard UNISIG SUBSET-036, the embodiment of the invention improves the real-time of the message processing flow, greatly reduces the time consumption and overcomes the shortcomings that the efficiency of transmitting a plurality of commands such as temporary speed limit command at the same road section and the like is low and constraints such as the number limit of the transmitted commands and the like in the prior art by checking the conditions in advance, setting a caching mechanism for a BCH calculation process, performing parallel operation, constructing a reverse query character table and the like.

Description

technical field [0001] The present invention relates to the technical field of train control, and more specifically, relates to a train control message processing method, device and system. Background technique [0002] The transponder system of the TCC system of the train control (train control) center is a point-type ground-to-train information transmission device, which provides ground fixed information and ground real-time information for the train control system. With the continuous improvement of train efficiency, the improvement of the transponder system has gradually become an important part of the improvement of traffic safety. [0003] The existing transponder system uses a large number of transponders and ground electronic units LEU. Since the message storage capacity of the LEU device is very limited (up to 1000), the messages sent by the transponder need to be pre-programmed and stored in the In the TCC host. [0004] In practical application, if train speed l...

Problems solved by technology

[0004] In practical application, if train speed limit scheduling is performed, according to the content of the train speed limit scheduling command, it is necessary to extract the pre-stored message corresponding to the command from the train control center equipment. If the command content is compared with the pre-programmed message Only when the documents are consistent can the command be accepted and executed by the train control center, otherwise it will be resent and compared. Due to the strict rules of dispatching commands such as temporary speed limit, for example, the efficiency value of temporary speed limit must be 45, 60, 80 , 120, 160km / h, the vehicle speed limit distance is 200, 500, 1000, 1500, 2000, 3000, 4000, 6000m, and the temporary speed limit scheduling is only allowed once between two stations on the same travel route , if temporary speed limit is required in multiple places on the same line, it is necessary to re-send the train limit dispatching command according to the fixed efficiency value of the temporary speed limit and combined with the vehicle speed limit distance, and re-send and compare, and this The number of command messages increases exponentially, which seriously affects the efficiency of command issuance and the execution of related commands;

[0005] In addition, the pre-programmed message checks in the prior art can only be carried out through manual checks and spot checks, and the existing missed check rate will lead to dispatching and execution errors and even train accidents. At the same time, due to the TCC The number of messages is huge, and the existing storage devices are fixed (mostly K5B dedicated hardware platforms). There are technical difficulties in expanding TCC message storage resources.
