In addition, the "electric vehicle charging control method using a license plate number recognizer" according to the present invention,

(e) As a result of checking in step (c), if it is not a pre-charged registered car, proceed with the charge and payment process using the payment module, and if the charge and payment process is normally performed, proceed with charging (S111 to S113). .

An electric vehicle charging control device and method using the license plate recognizer according to the present invention configured as described above will be described in detail.

First, when a vehicle enters a parking lot (including an electric vehicle charging facility) or a charging station where the charger 200, which is an electric vehicle charger, is installed, the vehicle recognition unit 203 photographs and records the entered vehicle through a CCTV camera, Vehicle license plate information is extracted from vehicle information captured using a number recognition algorithm, and the vehicle number in the extracted license plate information is recognized. When the vehicle number is recognized, the recognition information is transmitted to the charging control unit 205 (S101 to S103). That is, the recognized vehicle number information and vehicle image information are transferred to the charging controller 205 .

The vehicle entered through the vehicle recognition unit 202 is photographed and recorded, and license plate information is extracted from the photographed information using a license plate recognition algorithm to recognize the vehicle number. If the vehicle number is not recognized (vehicle license plate information) In a state where a part of the number is covered by damage or foreign matter, etc.), a method in which the user manually inputs the vehicle number using the keypad of the user interface unit 201 may be used.

Here, as the vehicle number recognition algorithm, a pattern matching algorithm or various known vehicle number recognition algorithms may be used. For example, a license plate recognition process using a pattern matching algorithm is as follows.

A binary image is extracted by pre-processing a grayscale image including a license plate area from the photographed vehicle image, and labels presumed to be letters are selected through a labeling process of the extracted binary image. Subsequently, the pattern most consistent with each of the selected labels is recognized, and the license plate area is extracted by determining the license plate type based on the arrangement rule and position of the linked numbers through pattern recognition and whether or not the image is reversed. Next, the position of the extracted license plate and the degree of inclination of each number are obtained, the image is rotated according to the horizontal and vertical standards, and normalized using an image filter. Next, the Korean area and the numeric area are separately extracted and recognized according to the type of the extracted license plate. Subsequently, the recognized pattern recognition value is corrected by applying the point sampling method, each character is individually recognized and then combined, and the validity of the combined recognition value is determined to accurately recognize the vehicle number through the process of extracting the recognition result. .

The vehicle information acquisition module 221 of the charging control unit 205 transmits the obtained vehicle license plate number and vehicle image to the electric vehicle management server 400 through the communication control module 227 so that the entered vehicle is a pre-charged registered vehicle. Acknowledgment is requested (S104).

Here, before visiting a charging station, the user of the electric vehicle can access the electric vehicle management server 400 using the user terminal 600 and register the electric vehicle as an electric vehicle to be charged. Here, in order to register as a pre-charged registered vehicle, the user's phone number and payment information for charging cost must be provided.

When the vehicle number and vehicle image are received from the charger 200 in a state in which the electric vehicle is registered as a charging target in advance, the electric vehicle management server 400 generates pre-charged vehicle information registered based on the received vehicle number and vehicle image. By searching, it is determined whether the corresponding vehicle number is an electric vehicle registered for charging in advance. As a result of this determination, if the vehicle number is a pre-charged registered electric vehicle, the authentication information of the pre-charged registered vehicle is generated as the pre-charge registration determination information, and if the vehicle number is a vehicle number that is not pre-charged registered, the information including the information not registered for pre-charge is generated. Pre-charge registration determination information is generated and transmitted to the charger 200 . The vehicle information may include a phone number of an electric vehicle user. This phone number can later be used to send pre-charge registration confirmation texts.

When the charger 200 receives pre-charge registration determination information from the electric vehicle management server 400 in step S105, it moves to step S106 and analyzes the received pre-charge registration determination information to determine whether it is a pre-registered vehicle registered for charging in advance. do. By analyzing the authentication information included in the pre-charge registration determination information, it is possible to easily determine whether an electric vehicle has been pre-registered as a charging target or an electric vehicle that has not been registered for charging.

Next, as a result of the determination, if the vehicle is not registered as a vehicle to be charged in advance, the charging and payment process proceeds in the same manner as before (S111). Thereafter, when the charge payment process is completed (S112), it moves to the step of starting charging, and if the charge payment process is not performed, it is determined that the charge has failed, and a charging impossible state is displayed through the display unit 206 (S113).

For example, whether the electric vehicle to be charged is registered for charging in advance is checked, and if it is not registered as a vehicle to be charged in advance, a general charging payment process is performed. , If payment processing is not performed during the charging and payment process, charging is not performed because it is judged as a charging failure.

Since the user needs to provide and manipulate a lot of information for the actual charging and payment process, it takes a lot of overall charging time and also causes inconvenience due to the multiple manipulations.

In order to solve the problem of time loss or inconvenience caused by the general charging payment process, the present invention analyzes the received pre-charging registration determination information and, if it is a pre-registered vehicle registered for charging in advance, the pre-charging registration determination information included in the pre-charging registration determination information Based on the contact information (for example, phone number) of the vehicle registrant, the text generation module 226 generates a pre-registration confirmation text to be sent to the vehicle registrant, and sends it to the user terminal 600 through the communication control module 227. It is transmitted to (S107).

Here, the reason for sending the pre-registration confirmation letter to the vehicle registrant is to more accurately confirm whether it is an electric vehicle registered as a pre-charging target.

Here, the pre-registration confirmation text sent to the user terminal 600 is in the form of a text that can be replied to as in the form of a setting inquiry.

When the user receives a pre-registration confirmation text (for example, "Is vehicle number 0000 an electric vehicle registered as a pre-charge target?") through the user terminal 600, a response icon (yes or no) included in the text Touch to make a response reply At this time, if the user has previously registered the vehicle as a vehicle to be charged, the user may touch the “Yes” icon.

The response reply text transmitted from the user terminal 600 is transmitted to the charging control unit 205 through the communication unit 210 .

The charging control module 223 of the charging control unit 205 checks the returned response, and if the vehicle registered as a target for charging in advance is correct, charging starts immediately without proceeding with charging and payment (S108 to S109). This is to reduce the user's charging time by omitting the charging and payment process when registering as a pre-charge target, as well as to improve inconvenience such as multiple key manipulations or information input by the user for the charging and payment process. .

The charging operation proceeds until charging is completed according to set conditions (S110).

In a state in which charging is completed, payment is made using pre-registered payment information of the vehicle registrant.

As described above, the present invention determines the presence or absence of pre-registration through vehicle number recognition in an electric vehicle charger having a license plate recognition (LPR) integrally built-in, and if the vehicle is pre-registered, a separate payment process is not performed. By immediately charging, the convenience of charging can be improved and the charging time can be shortened.

In addition, by implementing the vehicle number recognizer integrally with the electric vehicle charger, design cost and installation space restrictions due to the implementation of the two systems can be minimized, and the development time due to the development of the two systems individually can be shortened.

Although the invention made by the present inventors has been specifically described according to the above embodiments, the present invention is not limited to the above embodiments, and it is common knowledge in the art that various changes can be made without departing from the gist of the present invention.
