Detailed Description
The invention is described in detail below with reference to the figures and specific embodiments. The present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.
The utility model provides an outside electronic monitoring system of train door, as shown in figure 1, includes display, control module and all a plurality of cameras of being connected with control module, and the display is connected with control module, and each camera is located respectively in each carriage, and the figure of camera is the quadruple in carriage, and the both sides at the front portion and the rear portion in every carriage all are equipped with a camera.
The camera is an industrial high-definition camera.
The system also comprises a communication network consisting of a switch and a router, and the control module is connected with each camera through the communication network.
The control module comprises a foot pedal and a controller, the foot pedal is connected with the controller, and the controller starts or closes the display to display signals collected by the camera through input signals of the foot pedal.
The control module further comprises a control key, the control key is connected with the control module, and the controller controls the display to display the image collected by the corresponding camera through an input signal of the control key.
