the manual real-time observation of the state of the outer door requires arranging special personnel to walk in the train and monitor the opening and closing state of the outer door, so that the problem of labor cost is increased;
because the outer door switch needs manual operation every time, the problem of finger numbness or damage is easily caused by pressing the switch button of the outer door for a long time;
and because the stability of the train outer door is detected manually, the detection efficiency caused by the stability is lower, and the problems of large consumption of manpower and material resources are caused.
According to the detection device applied to the vehicle outer door, only one operator is required to be connected to a vehicle outer door control train line needing to be detected according to operation description steps, and then the whole process is not required to be stared at and controlled, the equipment can realize automatic operation detection according to a set mode, a corresponding outer door stability test is completed, and the effects of reducing labor cost and improving working efficiency are achieved.
And because the detection times are counted by the outer door detection device, the problem of missing or multiple meters caused by vague nerves or other conditions during manual operation is avoided, and the working efficiency and the counting accuracy are improved. And when a fault occurs, the warning function can be timely played, the train detection range is wide, and the cost and the labor cost are saved.
The above description is only an embodiment of the present invention, and is not intended to limit the scope of the present invention, and all equivalent structures or equivalent processes performed by the present invention or directly or indirectly applied to other related technical fields are included in the scope of the present invention.
