Fig. 1 is a block diagram of a structure of an acquisition end in an acquisition and monitoring system based on a charging pile, where the acquisition end 10 includes:

and the image acquisition module 12 is used for receiving the acquisition range sent by the server, generating an acquisition instruction according to the acquisition range, and acquiring and screening image information to obtain an image information base.
The functions of the acquisition end 10 are modularly subdivided, and the acquisition end 10 comprises two parts, namely a traditional image acquisition device for acquiring image information; secondly, some sensors are used for acquiring other parameters; the other parameters mainly comprise physical parameters and environmental parameters, wherein the physical parameters are some electrical parameters and physical properties of the charging pile, and the current and the temperature are taken as representatives; the environmental parameters are mainly air parameters including air flow characteristics and air important components; the type of target gas is not unique and is typically a combustion product that is used to monitor whether a burn out has occurred in the charging post or the vehicle.
Fig. 2 is a block diagram of a structure of an image acquisition module 12 in an acquisition end, where the image acquisition module 12 includes:
the boundary determining unit 121 is configured to receive an acquisition range sent by a server, acquire an acquisition end view angle range, and determine a rotation angle boundary of the acquisition end according to the acquisition range and the view angle range;

and the image screening unit 124 is configured to sort the acquired to-be-detected images according to a time sequence, and screen the sorted to-be-detected images to obtain an image information base.
The above-mentioned content defines the image acquisition module 12 specifically, first, the acquisition range sent by the receiving server side is a sector, the acquisition range refers to the view angle range of the image acquisition device, and it also can be a sector, and the station range of the image acquisition device can be determined according to the two sectors, so as to determine the rotation instruction; then, the rotation starting point of the image acquisition device is determined according to the rotation angle boundary, and it is worth mentioning that the rotation starting point of the image acquisition device can slightly exceed the rotation angle boundary, so that the problem of boundary acquisition distortion is prevented; and finally, sequentially generating rotation instructions and acquiring images.

In an example of the technical solution of the present invention, it is assumed that the image acquisition device rotates from left to right, and in the acquired image to be detected, the contour at the rightmost end is an unclosed contour, which means that the other half is in the next image, and at this time, the leftmost end of the contour is taken as the center line of the next image; if the next image is still an unclosed contour, the image is marked and the contour recognition unit 122 and the rotation execution unit 123 are repeatedly executed.
