Specifically, the image capturing module 1 is disposed on an upper surface of an inner side of the box body, and is configured to capture image information in the box body, and send the image information to the server 7 through the network transmission module 5. Because the external dimension of the box body of the splice box is smaller, the dimension of the box body is about 400mm long, about 200mm wide and about 40mm high, the camera module 1 adopts a micro-wide-angle lens, and the camera module 2 can be matched with the lighting module to shoot videos or images in a narrow box body internal space, so that the condition of cables in the splice box can be shot in a large range and clearly, the situation that a shot picture is out of focus and is fuzzy, and whether an optical cable fails or not can not be distinguished is prevented, and the connection condition of the optical cable in the box body is intuitively known.

The information association module 8 may be an image processor, and is electrically connected to the camera module 1, and configured to associate the image information collected by the camera module 1 with the position information output by the positioning module, that is, to display the serial number of the splice closure, the serial number of the tower and the position coordinate information and the image information captured by the camera module 1 on the same display screen synchronously.

In one of the scenes, after a worker selects a certain splice closure through remote operation, the position information corresponding to the splice closure and the image information output by the camera module corresponding to the splice closure are spliced into the same image to be displayed, so that the position information is displayed in the surrounding area of the image information, and the position information corresponding to the splice closure can also be combined with the image information as a watermark to realize synchronous display of the position information and the image information. Therefore, when the operation and maintenance staff checks the image information acquired by the camera module 1 through the remote monitoring terminal, the number of the splice box corresponding to the camera module 1, the corresponding tower pole number and the position coordinate can be checked synchronously, the corresponding relation is not required to be distinguished from a plurality of image information and a plurality of position information, and the efficiency of determining the fault position is further improved.
