Insulation fault diagnosis method and system, storage medium and electronic equipment

The invention discloses an insulation fault diagnosis method and system, a storage medium and electronic equipment, relates to the technical field of hydrogen fuel cell vehicles, and mainly aims to solve the problems that an existing insulation fault processing mode is simple, the time consumed in the process of waiting for service personnel to process is long, the user experience feeling is reduced, and the fault diagnosis efficiency is improved. And the time cost and the labor cost consumed by troubleshooting are also increased. The method includes: acquiring insulation resistance data of a target object in real time; when it is monitored that the insulation resistance value data is lower than a preset insulation resistance value threshold value and exceeds a preset duration threshold value, alarm prompt information that the insulation resistance value is too low is output; and based on the alarm prompt information, triggering an insulation fault diagnosis thread to perform insulation fault diagnosis on the
