Railway signal insulativity testing method and system

The invention relates to a railway signal insulativity testing method and a railway signal insulativity testing system. The railway signal insulativity testing method comprises the following steps: acquiring acquisition information of a railway signal sensor at fixed time intervals; converting the collected information into a preset format; receiving insulation test task information; distributing a test task according to the insulation test task information and the working or idle state of each signal measurement module, and obtaining task distribution information; according to the task allocation information, sequentially executing test tasks to obtain test result information; and comparing whether the test result is in a built-in reference value range, and if the test result exceeds the reference value range, sending out a warning signal. Compared with the prior art, on the basis of collecting and summarizing the information of the railway signal sensor, the insulating property of the line can be tested. 本发
