Abstract

The invention discloses an interlocking Boolean logic dynamic generation system and a dynamic generation method in the field of urban rail transit. The system comprises a component deployment module,an interlocking tabulation module, a semantic rule module and a logic generation module by which the Boolean logic data are dynamically generated; and a data encryption module which is used for carrying out data encryption rearrangement according to the generated logic data to generate a Boolean logic file. According to the present invention,the misoperation of the file in the later period is prevented, and the data security is ensured. According to the technical scheme of the invention, a context-independent LL (K) mode is adopted to analyze interlocking logic and dynamically generate and output the interlocking logic; the interlocking developers only need to modify the interlocking logic according to a predetermined grammar rule in the later period, so that the latest Boolean logic can be dynamically generated in real time without changing any code, the rule and generation decoupling is achieved, the workload of signal technicians is greatly reduced, the safety of logic data is ensured through introduction of the encryption technology, the reliability is high, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of urban rail transit signal control, in particular to a generating system of Boolean logic of an interlocking system. Background technique [0002] The correct and stable operation of interlocking equipment is the premise of healthy and orderly operation of rail transit, which directly affects the safe operation of trains, and even the personal and property safety of passengers. Interlocking Boolean logic BA (Boolean Algebra) is a set of expressions to ensure stable and orderly cooperation between interlocking devices, and its operation results are the guarantee and basis for the safe operation of interlocking devices. [0003] Due to the complex coupling relationship between interlocking equipment, it is common practice for experienced signal professionals to sort out and calculate the linkage relationship of each equipment, and manually write BA. However, the problem brought by manual compilation is that BA has a ...
