Description
Technical Field
The invention relates to the field of rail transit equipment safety monitoring, in particular to a safety card control method for cable insulation testing based on a signal centralized monitoring system.
Background
In a rail transit system, a large number of signal cables are used for signal equipment, and the insulation performance of the cables needs to be detected regularly. And in the insulation test of the cable, a station machine of the signal centralized monitoring system sends a test command to the insulation test host machine, and the insulation test host machine returns the insulation resistance value to the station machine interface for display after the test is finished. The insulation test adopts a 500V direct current voltage on-line test method for testing, and a series of safety control cards are needed for triggering a station machine of a test activity in order to guarantee the safety of signal equipment and the personal safety of testers.
At present, the cable insulation test is triggered to execute the test by a test button of a station machine interface of a signal centralized monitoring system. The change of the interface button is equivalent to the collection of one switching value from 0 to 1. This has the disadvantage that the single point of control, both in hardware and software execution, is too dependent on this variable to be safe. The 0 may be erroneously changed to 1 because of electromagnetic compatibility or hardware random failures, software execution failures, etc. Although the front-end steps have many guards, the results of these guards do not directly act on the final test command. Currently, the test command only hooks the only test command button after the cable routing is completed.
