Description

[0002] When new construction, renovation, major overhaul and other signal projects are opened and constructed in railway yards, due to reasons such as construction key point time limits, interference from abnormal train reception and departure, influence of pre-station construction progress and equipment debugging, etc., the opening progress of signal equipment is seriously affected. Especially for the transformation of existing lines, due to the large workload of switch equipment disassembly, replacement, many test contents, imperfect simulation circuit connection conditions, incomplete equipment debugging, etc., some switch equipment does not have test conditions, resulting in the inability to test subsequent signal machines, code conversion, and equipment such as sections and station connections. Currently, during switch tests, to improve test efficiency, a method of temporarily building a simulation test circuit is used for equipment debugging.
