Embodiment 1

[0046] This embodiment provides a method for encoding train operation control system messages, the encoding method comprising:

[0047] Based on xml language, the train operation control system message format is described according to the structure of message type StructDefinitions, message or package StructDef, field FieldDef, and field value ValueDef;

[0048] According to the value of each field of the train operation control system message, according to the message description format, generate hexadecimal byte stream or binary bit stream data.

[0049] Wherein, the structure of the message type StructDefinitions includes: the name identity of the message type, the Chinese meaning tip of the message type, and the meaning entip of the message type in other languages. Described message type can be transponder message, also can be the train control system message types such as the wireless communication message of ATP and RBC, the vehicle ground communication message of CBTC s...

Abstract

The invention discloses a method and device for encoding and decoding train operation control system messages. The encoding method includes the following steps: based on xml language, train operation control system messages are classified according to message type StructDefinitions, message or packet StructDef, field Describe the structure of FieldDef and field value ValueDef; according to the value of each field in the train operation control system message, according to the message description format, generate hexadecimal byte stream or binary bit stream data . The encoding and decoding method of train operation control system message of the present invention describes the message based on xml language, and has the advantages of easy function expansion and strong universality; it is suitable for the encoding of various train operation control system message types. Decoding can ensure the accuracy of the message.

Description

technical field [0001] The invention belongs to the field of train operation control systems, in particular to a method and device for encoding and decoding messages of the train operation control system. Background technique [0002] The message of the train operation control system is the basis for ensuring the safety of the train, and the goal of encoding and decoding the message information is to ensure the correctness of the message. The method and tool for encoding and decoding messages of the train operation control system can not only save manpower, but also can verify the messages. For example, the development process of Siemens message encoding software in Germany is to first check the user data table provided by the design unit, then design the message, and finally output the message and use the hash algorithm to calculate the message to obtain each message The hash value of the hash operation. [0003] The encoding and decoding of the prior art has the problem ...
