Referring to fig. 2, before acquiring vehicle information based on a preset reader/writer, the following steps are included:
s201, judging whether the vehicle is an electric vehicle or not based on a preset image recognition algorithm.
In the first embodiment, because the color of the license plate of the electric vehicle is different from the color of the license plate of the fuel vehicle, the color of the license plate of the vehicle can be recognized based on an image recognition algorithm, and whether the vehicle is the electric vehicle or not can be recognized based on the color of the license plate; in the second embodiment, since the number of characters of the license plate number of the electric vehicle is different from the number of characters of the license plate number of the fuel vehicle, the number of characters of the license plate number can be identified and obtained based on the image identification algorithm, and whether the vehicle is the electric vehicle or not can be judged based on the number of characters.
It should be noted that, in addition to the above two embodiments, the number of the license plate can be obtained based on the information of the electronic tag embedded in the license plate obtained by the reader-writer, and the number of characters of the number of the license plate can be obtained, so as to determine whether the vehicle is an electric vehicle, which is not described herein again.
And S202, if the vehicle is a non-electric vehicle, sending out a voice prompt.
And if the vehicle is a non-electric vehicle, sending out prompt information for prompting that the non-electric vehicle charging station cannot enter.

s301, obtaining a vehicle image.
The vehicle image is obtained based on a camera preset in the charging station.
S302, obtaining a license plate image based on the vehicle image.
Because only the license plate position contains characters in the vehicle image, the vehicle image is segmented after the vehicle image is obtained, and the license plate image containing the characters is obtained. Specifically, the position of the license plate in the vehicle image is located based on the characteristics of the license plate characters, and segmentation is performed.
In specific implementation, after obtaining a license plate image, the license plate image may be an oblique image, and at this time, the license plate image may be subjected to oblique correction.

In specific implementation, the number of characters of the license plate of the fuel vehicle is different from that of the license plate of the electric vehicle, so that whether the vehicle is the electric vehicle or not can be judged based on the number of the characters. For example, the number of characters of a license plate of an electric vehicle is 8, the number of characters of a license plate of a fuel vehicle is 7, and if the number of the obtained characters is 7, the vehicle is judged to be a non-electric vehicle.
The implementation principle of the embodiment is as follows: and judging whether the electric vehicle is the electric vehicle according to the number of the characters, so that the identification accuracy of the electric vehicle is improved conveniently.

And S403, if the vehicle is not parked in the charging parking space corresponding to the charging pile, judging that an idle parking space exists in the charging station.
The implementation principle of the embodiment is as follows: at first the user state to filling electric pile judges, if the user state who fills electric pile is the non-charging state, whether the vehicle has been parked on the charging parking stall of judging this moment that fills electric pile corresponds, if the vehicle has not been parked on the charging parking stall and judge that the charging station has idle parking stall, judge through the user state who fills electric pile at first promptly, then whether park the vehicle on the parking stall that fills electric pile corresponds and judge, effectively improved the accuracy of judging idle parking stall.
In step S403 of the embodiment shown in fig. 4, if the charging station does not have an empty parking space, the charging station may also determine whether a vehicle is parked in the parking space or not based on the usage status of the charging pile, and if the charging station does not have an empty parking space, the vehicle may be managed based on the vehicle information. This is explained in detail with reference to the embodiment shown in fig. 5.
