Abstract: This paper introduces a type of software based on CAD platform which takes signal layout plans as software input and automatically generates interlocking tables. The paper also provides the design algorithms of main function modules. Based on the secondary development interface provided by CAD, the CAD drawing block method is used to provide a unified signal element and realize the signal layout plan standardization processing, so that the software can obtain all the information needed to generate interlocking tables from the standardized signal layout plans. In addition, the generated interlocking tables can be provided as standardized engineering design drawings to other parties, thus improving the compiling efficiency of the interlocking tables and greatly reducing the probability of error.

Key words: interlocking table, signal layout plan, secondary development by CAD
