[0032] A further implementation method uses a SQLLite3 lightweight file database to store intermediate data, which reduces memory overhead and allows better adaptation in different environments.

[0034] A further implementation method is to construct a minimum logical unit Link, obtain the distribution of equipment of different types in the drawing by identifying the lines in the drawing and the positions of the equipment reference points, take the axle counter and the turnout as the starting and ending points, and construct a link sequence connecting the entire line. The equipment existing on the starting and ending lines is the equipment in the link. The equipment type that needs to be exported is identified, and the equipment can be classified, identified and exported.

[0035] A further implementation method adopts a five-layer architecture of presentation control layer, business logic layer, class library support layer, data access layer and data layer, which has the characteristics of easy maintenance and easy expansion.

[0036] In a further implementation method, the main fields of the exported trackside signal equipment record sheet include number, centralized area name, equipment 1 name, equipment 2 name, equipment 1 centralized area number, equipment 2 centralized area number, final distance, and engineering design value, where the equipment 1 name and the equipment 2 name are the names of the two devices in the logical direction sequence that need to be measured on the link, respectively, and the engineering design value is the drawing design distance of the two devices, such as Figure 3 shown.

[0037] In a further implementation method, the design distance value between devices is comprehensively calculated based on the kilometer marks between devices and the length of the chain between the kilometer marks, and is recorded and output in centimeters.
