[0002] The overhead contact network operation vehicle is an important equipment for electrified railway transportation. It carries and enables maintenance personnel to inspect, test, repair and troubleshoot the overhead contact network. The lifting platform of the operation vehicle has no voice prompts and intuitive and visible operation prompts during use, which can easily cause misoperation beyond the zone and cause electric shock hazards. Specifically, during operation, the driver cannot know whether the operator on the platform is operating; after the operation vehicle is started, the engine sound is loud, and the surrounding personnel cannot know at the first time when the leader of the operation platform is operating; the operator cannot know whether to turn left or right. As a result, the driver does not know that the operation platform is in operation during the use of the operation vehicle lifting platform, and the vehicle is started by mistake. After the engine of the overhead contact network operation vehicle is started, the sound is so loud that the personnel on the operation platform cannot hear the operating instructions of the leader of the work, resulting in misoperation of the platform.
