Chain development method suitable for multiple data generation tools

The invention discloses a chain development method suitable for multiple data generation tools, and relates to the technical field of data generation tool development. Compared with a traditional method that all levels of tools are completely developed separately, the problem that the tools and the data are inconsistent at the upper level and the lower level can be found in advance, the consistency testing cost is greatly reduced through chained scanning and calling of the tools, and the development efficiency of the multi-data tools in the rail transit system can be remarkably improved. Independent development directories are set for all tools in the system, and development of the tools does not affect one another. And the output data of each line and each tool is managed in the output area, so that the data exchange among different tools is facilitated, and each tool developer can use abundant line data to debug, test and the like. According to the method, the tool requirements are divided into the data int
