[0002] Offshore substation is a general term for platforms built on the sea, which are equipped with high-voltage AC transformation and high-voltage DC conversion equipment, as well as related living facilities.

[0003] Traditional real-time safety monitoring of offshore substations is mostly carried out to monitor the equipment when in use, and most of the equipment itself or the controller used to control the equipment monitors the implementation data of the equipment. First, the safety issues in offshore substations include more parts and are not fully covered. Second, it is difficult to locate during maintenance because the equipment is relatively dense and the equipment volume is large. As a result, there are too many sensors and sensor inputs for monitoring safety. Therefore, after observing abnormal sensor data, it is difficult to find the problem location on the actual site and it is difficult to locate. Summary of the invention

[0004] The purpose of the present invention is to provide a real-time safety monitoring system and method for offshore substations based on multi-sensor fusion, so as to solve the problem that after the sensor data in the prior art mentioned in the above background technology is abnormal, it is difficult to find the problem location and locate it in the actual site.
