Abstract: To provide an automatic configuration method for generating interlocking data corresponding to all valid equipment codes at rail transit stations based on Boolean algebra and according to interlocking information tables, external interface information tables and custom equipment query syntax, this process is studied from three aspects: automatic configuration input, universal syntax search and Boolean logic and communication code generation. The input is converted into fixed-format interlocking logic information using an interlocking tool. The syntax definition format, search form processing and logical operation process of the universal search syntax stage are analyzed in-depth, and the custom universal search syntax is parsed. Based on the search form provided by universal search syntax, relevant content is queried and logical operation is performed on fixed-format interlocking logic information to obtain valid equipment information and code corresponding to each parameter and generate Boolean logic expressions for each code. The input and output flags and type codes of the communication parameters are specified using the corresponding search form in the syntax stage, and communication codes for operation machine and interlocking machine are generated. The feasibility of the changes brought by this scheme is analyzed from the perspective of data configuration format and search form. The automatic configuration scheme for rail transit station computer interlocking data based on Boolean algebra proves to be technically feasible.
