Embodiment

[0069] Such as figure 1 Shown, a kind of safety redundant code processing method that is used for vehicle-mounted ATP system, this method comprises the following steps:

[0070] Step 101, the pre-generated signature, configuration information, and unsafe C language code are processed by the input and error detection module;

[0071] Step 102, the processed pre-generated signature, configuration information, and unsafe C language code are processed by the pre-compiler of the safety redundant coding compiler to generate an intermediate code file, and the intermediate code file is passed through the middle of the safety redundant coding compiler. The code compiler generates compensation constants and coded C language code after processing;

[0072] Step 103, the safety redundant coding optimization module generates an auxiliary language code;

[0073] Step 104, generating safety redundant code after processing the compensating constant, the coded C language code and the auxilia...

Abstract

The invention relates to a safety redundant coding processing method for a vehicle-mounted ATP system, which comprises the following steps: (1) processing pregenerated signatures, configuration information and unsafe C language codes by an input and error detection module; (2) processing the processed pregenerated signatures, configuration information and unsafe C language codes by a precompiler of a safety redundant coding compiler to generate intermediate code files, and processing the intermediate code files by an intermediate code compiler of the safety redundant coding compiler to generate compensation constants and coded C language codes; (3) generating auxiliary language codes by a safety redundant coding optimization module; (4) processing the compensation constants, the coded C language codes and the auxiliary language codes by a general compiler and a connector to generate safety redundant codes; and (5) processing the safety redundant codes by an output and error detection module to be output. Compared with the prior art, the invention has the advantages of ensuring safety operation of the system, and the like.

Description

technical field [0001] The invention relates to a coding method, in particular to a safety redundant coding processing method used in a vehicle-mounted ATP system. Background technique [0002] The railway signal industry is directly related to the safe operation of trains and the safety of people's lives and properties. For a safety product in the railway industry, RAMS (reliability, availability, maintainability, safety) requirements must be met. Especially for the vehicle-mounted ATP system, which directly controls the safe operation of the train, it must reach the system safety integrity level of SIL4. Ordinary software and hardware environment cannot guarantee the security of the system, and the calculation errors caused by internal and external reasons during the operation of the system cannot be found, which will eventually lead to serious consequences. The introduction of safety redundant coding in this field will effectively improve the safety level of the system,...
