Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicle charging, and in particular to a control method for charging pile start / stop identification and information display and related equipment. Background Art

[0002] At present, there are many deficiencies in the daily use efficiency of public charging piles, especially during peak hours. When new car owners are looking for charging parking spaces, they often cannot intuitively perceive the charging status, charging progress, and expected charging end time of each charging gun in the entire charging station. This opaque information leads to a lack of effective prediction when car owners are waiting in line for charging, and they cannot reasonably arrange charging plans, which easily causes congestion and disorder. This not only seriously affects the charging efficiency of individual car owners, but also greatly restricts the overall operating efficiency of charging stations.

[0003] In addition, the drawbacks of existing technologies are also reflected vividly in the charging start-stop process. Take the scan code start as an example. Although this method seems convenient, it often takes a lot of time in actual operation for various reasons. The owner needs to get out of the car, find the QR code on the charging pile, turn on the smartphone, scan the code and wait for the system to respond. This series of steps is not only cumbersome, but also easy to extend the waiting time during peak hours due to network delays or system busyness.

[0004] What's more serious is that the code scanning startup method is not very friendly to the users of public stations. With the development of technology, smartphones have been popularized to most people, but there are still some people, such as the elderly or those who are not familiar with smartphones, who will encounter great difficulties when using the code scanning startup method. This group of people may need to spend more time and energy to learn how to use smartphones to scan codes, and may even cause charging failures due to operational errors or unclear understanding. This not only increases their learning costs, but may also cause them to resist charging services, thereby further reducing the efficiency of public charging piles.

[0005] In addition to the code scanning method, the existing technology also has some other drawbacks. For example, the payment system of some charging piles may not be stable or flexible enough, causing car owners to encounter various problems during the payment process; at the same time, the charging power and power distribution method of some charging piles may also be different, causing car owners to spend longer waiting for the battery to be fully charged. These technical drawbacks have restricted the efficiency of the use of public charging piles to a certain extent and need to be further improved and optimized.

[0006] In summary, the existing public charging piles have many shortcomings during use, and there is an urgent need for a control method and related equipment for charging pile start and stop identification and information display to solve the above problems, improve charging efficiency, and enhance user experience. Summary of the invention

[0007] In order to overcome the defects of the above-mentioned prior art, the purpose of the present invention is to provide a palmprint recognition control method and related equipment for starting and stopping a charging pile, so as to solve the technical problem of how to improve the recognition start and stop efficiency and effective display of the charging pile in the prior art.

[0009] Preferably, in the step of entering the palmprint information data into the palmprint database, the palmprint information data is preprocessed, and the preprocessing process includes denoising, contrast enhancement and normalization.

[0010] Preferably, in the step of entering the palmprint information data into the palmprint database, the entered palmprint information is encrypted using an AES algorithm, and the specific process includes: A key length is selected according to the palmprint information, a random number generator is used to generate a random byte sequence, and the generated random byte sequence is truncated or padded to the required key length to obtain a ciphertext, which is an encrypted representation of the palmprint information.

[0011] Preferably, in the step of identifying the acquired palmprint information with the palmprint information in the palmprint database to obtain the identification result, a biometric recognition algorithm is used to identify the palmprint information. The specific process is as follows: Extracting the feature points of the acquired palmprint information from the feature points of the palmprint information in the palmprint database, and calculating the Euclidean distance or Hamming distance between the feature points to obtain similarity data; A threshold is set. When the similarity data is greater than the threshold, the authentication is passed, that is, the identity authentication is qualified. Otherwise, it fails, that is, the identity authentication is unqualified.

[0012] Preferably, identity authentication is performed based on the identification result. When the identity authentication is qualified, the charging information of the charging pile is received and displayed. The charging information includes the charging status of the charging pile, charging speed, charged amount, vehicle SOC estimated charging completion time and charging cost.

[0013] In a second aspect, the present invention further provides a control system for charging pile start / stop identification and information display, comprising: An input module is used to input palmprint information data into the palmprint database; The recognition module is used to recognize the acquired palm print information and the palm print information in the palm print database to obtain a recognition result; The display module is used to perform identity authentication according to the recognition result. When the identity authentication is qualified, the charging information of the charging pile is received and displayed; The starting module is used to start the charging pile according to the information display results, and complete the control work of charging pile start and stop identification and information display.

[0014] Furthermore, the recognition module includes a feature point processing module and a similarity comparison module; A feature point processing module is used to extract the feature points of the acquired palmprint information from the feature points of the palmprint information in the palmprint database, and calculate the Euclidean distance or Hamming distance between the feature points to obtain similarity data; The similarity comparison module is used to set a threshold. When the similarity data is greater than the threshold, the authentication is passed, that is, the identity authentication is qualified. Otherwise, it fails, that is, the identity authentication is unqualified.

Users do not need to carry additional identity identification tools, and can quickly complete identity authentication through palmprints, which simplifies the operation process and improves the user experience. After the identity authentication is qualified, the system can receive and display the charging information of the charging pile, including charging status, charging speed, charged amount, vehicle SOC estimated charging completion time, etc., providing users with comprehensive charging information, which is convenient for users to understand and manage the charging process.

[0019] Furthermore, the AES algorithm can effectively protect the palmprint information from being accessed or tampered with by unauthorized personnel. Through encryption processing, even if the palmprint database data is accidentally leaked, it is difficult for attackers to directly obtain the original palmprint information, thereby greatly improving the security of the data.

[0020] Furthermore, by extracting the feature points of the palmprint information and calculating the Euclidean distance or Hamming distance between the feature points, the similarity between the palmprint to be identified and the palmprint in the palmprint database can be accurately measured. Compared with the traditional image matching algorithm, this method has higher recognition accuracy and robustness, and can more accurately identify legitimate users. A threshold is set for identity authentication, and only when the similarity data is greater than the threshold, the identity authentication is considered qualified. This measure effectively prevents misidentification caused by insufficient similarity, and further enhances the security of the system. At the same time, due to the uniqueness and stability of palmprint information, this method has a high anti-counterfeiting ability and can resist attacks such as forged palmprints.
