[0018] Three implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0019] The first implementation method: Figure 1-Figure 2 An intelligent electronic license plate for an electric vehicle is shown, comprising an intelligent control system and a license plate body 1, wherein the intelligent control system comprises an identification interaction module, a GPS module, an encryption module, an identity authentication module, an emergency service module and an anti-tampering module, wherein the identification interaction module comprises an identification block equipped with an RFID chip and an NFC chip, which is used to assist in realizing long-distance automatic identification of the vehicle and realize near-field communication, the GPS module is used to assist in realizing vehicle positioning, navigation and information sharing, the encryption module comprises an encryption unit, an anti-counterfeiting unit, a data protection unit and a key management unit, the anti-tampering module comprises a physical protection unit, a data integrity verification unit and an audit tracking unit, and the identity authentication module comprises a biometric module, a digital signature module and a dynamic authentication module; The physical protection unit includes anti-theft screws, and the license plate body 1 is installed on the vehicle through the anti-theft screws, the LED display screen 2 and the identification block are installed inside the license plate body 1, and a shielding plate is installed inside the license plate body 1; The LED display screen 2 can dynamically display the information of the license plate body 1, such as the license plate number, vehicle status, etc. In different scenarios, different contents can be displayed, such as displaying fault information when a vehicle breaks down, displaying relevant promotional information during special events, etc. The dynamic display function increases the information carrying capacity and practicality of the license plate.

[0020] The information on the LED display can be adjusted in real time through remote updates. Traffic management departments can update the display content on the license plate in a timely manner as needed, such as issuing traffic tips, safety information, etc. At the same time, car owners can also set the display content according to their own needs to achieve personalized information display.

[0021] It also includes a mobile APP used in conjunction with the intelligent control system, and the mobile APP and the license plate body 1 realize data retrieval through the cloud database. The mobile APP supports vehicle status viewing, vehicle location query, vehicle historical data viewing, and vehicle remote control and remote update. The remote update includes the update of some information of the license plate body 1 and the update of security patches of the intelligent control system.

[0022] Specifically, the vehicle location information obtained by the GPS module can be shared with other systems. For example, it can be shared with the intelligent transportation system for traffic flow monitoring and traffic signal control; it can be shared with the parking lot management system to realize functions such as intelligent parking guidance. Through data sharing, the operating efficiency and intelligence level of the entire transportation system can be improved.

[0023] Encryption technology provides reliable protection for the data of smart license plates. Whether it is data transmission between vehicles and traffic management departments or data storage inside smart license plates, the encryption mechanism can ensure the security and integrity of data. Even if the data is intercepted during transmission, attackers cannot obtain valid information.

[0024] The smart license plate system has an audit tracking function that can record all operations and status changes of the license plate. These records can be used as the basis for auditing and tracing. When a security incident occurs, the root cause of the problem can be quickly located and the responsibility can be identified. At the same time, the audit tracking function can also deter potential security threats and reduce the occurrence of illegal operations.

[0025] In addition, the anti-theft screws are physical protection to prevent the license plate body 1 from being illegally disassembled or tampered with. In addition, the use of the shielding plate is mainly used to prevent electromagnetic shielding.

[0026] Dynamic authentication means that the identity authentication information will be dynamically updated with the change of time or operation. In the smart license plate system, dynamic authentication can be performed by means of dynamic passwords, one-time passwords, etc. This authentication method can effectively prevent the password from being stolen and replayed, and improve the security and reliability of identity authentication.

[0027] The intelligent control system also includes an additional function module and an intelligent reminder module. The additional function module includes an all-in-one environmental detection sensor for detecting the external environment of the vehicle. The intelligent reminder module is used to provide reminder notifications of vehicle maintenance information, insurance expiration information, violation information and other personalized information.

[0028] Specifically, through the cloud, the information of the smart license plate can be updated remotely. For example, when the owner's contact information, vehicle information, etc. change, the new information can be uploaded to the cloud in a timely manner through the mobile application or management platform and updated to the smart license plate. This ensures the accuracy and timeliness of the license plate information.

[0029] With the continuous development of technology and the changes in user needs, the functions of smart license plates can also be upgraded through remote updates. For example, adding new sensor functions, optimizing communication protocols, etc. Remote function upgrades can allow smart license plates to always maintain advanced performance and functions, providing better services to users.

[0030] In order to ensure the security of the smart license plate system, it is very important to promptly repair possible security vulnerabilities in the system. Through remote updates, security patches can be pushed to the smart license plate in a timely manner to enhance the security and stability of the system.

[0031] The emergency service module includes an emergency sending unit, an emergency call unit and a real-time data sharing unit. The emergency sending unit automatically sends the vehicle's location information to the emergency service department when an emergency occurs in the vehicle; The emergency call unit is used by the car owner to directly contact the emergency service center by pressing the emergency call button in the car when encountering an emergency. During the call, the intelligent control system will automatically upload the vehicle's location information; The real-time data sharing unit shares the vehicle's real-time data with emergency services in an emergency.

[0032] Specifically, the emergency service integration function can achieve multi-party collaborative rescue. The smart license plate system can share data and work together with relevant departments such as traffic police, hospitals, and insurance companies to improve the overall efficiency and effectiveness of rescue. For example, traffic police can quickly reach the scene of the accident to divert traffic based on vehicle location information, hospitals can make rescue preparations in advance, and insurance companies can intervene in the claims process in a timely manner.

[0033] The encryption unit adopts AES encryption algorithm, the anti-counterfeiting unit verifies the legitimacy of the license plate body 1, the data protection unit sends an alarm signal when an unauthorized operation status is detected, the key management unit includes key generation, storage, distribution and update to ensure the security of the key, the data integrity verification unit uses hash algorithm to verify data integrity during data transmission, and the audit tracking unit records all operations and status changes of the license plate.

[0034] Specifically, the AES encryption algorithm is an advanced encryption standard with high-strength encryption capabilities. Applying AES encryption technology in smart license plates can encrypt sensitive vehicle data, such as license plate numbers, owner information, driving records, etc. Only authorized systems and devices can decrypt and access this data, effectively preventing data from being stolen and tampered with during transmission and storage.

[0035] Through encryption technology, the identity information of the license plate can be encrypted and identified. Only legal smart license plates can pass encryption verification, effectively preventing the use of forged license plates. This is of great significance for maintaining traffic order and ensuring road safety, and reducing the occurrence of illegal acts such as fake license plates.

[0036] Figure 4 As shown, the operation steps of the key management unit are as follows: A1. After the key management unit generates the key, it first performs storage processing, and then adds the generated key to the verification lock block, which includes a hidden lock block and a display lock block; A2, after the key with the verification lock block is sent to the data transfer and forwarding center, the data transfer and forwarding center generates an unlocking block that matches the verification lock block in A1, and then the key with the verification lock block is verified and distributed; A3. During the verification and distribution process, the unlocking block and the verification lock block in A2 need to be verified and unlocked. After a single pass, the key is distributed from the data transfer forwarding point to the receiving APP. If it fails once, the key is changed and sent to the receiving APP.

[0037] Specifically, the security of encryption technology also depends on the effective management of keys. In the smart license plate system, a complete key management mechanism needs to be established to ensure the security of key generation, storage, distribution and update. Only in this way can the long-term effectiveness and reliability of encryption technology be guaranteed.

[0038] The key management unit verifies the lock block and verifies the distribution process, so that the key can be sent to the correct transit forwarding location when it is sent to the transit forwarding location, avoiding being intercepted and forwarded to criminals by other disguised transit forwarding locations. When the wrong transit forwarding location is identified, the key is replaced to confuse the criminals into thinking that the forwarded key has been successfully intercepted and forwarded, thereby reducing subsequent continuous attacks and interceptions.

[0039] In addition, a data integrity verification mechanism is used during the data transmission and storage process of the smart license plate. The data check code is generated by performing hash operations on the data. When receiving and using the data, the check code will be verified to ensure that the data has not been tampered with during transmission and storage. If the check code does not match, the system will refuse to use the data and issue an abnormal prompt.

[0040] The second implementation method: Figure 5 It is shown that a clearing component is installed on the license plate body 1. The clearing component includes a platform block 3 embedded in the surface of the license plate body 1, and a nozzle is installed at the bottom of the platform block 1, and a water supply pipe connected to the nozzle is installed through the interior of the platform block.

[0041] A protruding platform block is inlaid on the surface of the license plate body 1, and shooting lenses 4 are respectively installed on the front and bottom of the platform block. A read-write lens 5 located above the identification block is installed on the bottom of the platform block, and the installation position of the read-write lens 5 and the identification block are located on the same axis. The shooting lens 4 and the read-write lens 5 are both connected to the intelligent reminder module signal.

[0042] Different from the first embodiment, in this embodiment, the shooting lens 4 on the license plate body 1 is mainly used to shoot the surface of the LED display screen 2 and the identification block to check whether there are any obstructions. If there are any obstructions, the intelligent reminder module is activated to remind the owner through the mobile APP. If the owner is about to drive, the owner will get off the car and manually clean the obstructions. If obstructing dust appears on the license plate body 1, the electronic valve on the surface of the water supply pipe is opened (the other end of the water supply pipe is connected to the water tank on the vehicle body, which is a prior art and will not be elaborated on), and water is supplied to the nozzle to clean the surface of the license plate body 1, ensuring that the license plate body 1 can be unobstructedly identified.

[0043] In addition, the use of the read-write lens 5 can perform read-write scanning on the chip on the identification block to perform function verification and determine whether the chip is in a normal functional state. When the function is abnormal, the intelligent reminder module is used to remind the owner to perform chip maintenance and replacement operations.

[0044] The third implementation method: Figure 3 It is shown that the emergency service module includes a positioning correction unit, and the working steps of the positioning correction unit are as follows: S1. When the vehicle encounters a collision accident (the GPS module is connected to the sensor signal on the vehicle for detecting collision), the GPS module records the location information W1 of the license plate body 1 when the vehicle encounters the collision accident, and records the location information W2 of the license plate body 1 after a specified period of time; S2. Compare whether the difference between W1 and W2 exceeds the safety threshold. If so, the vehicle position information sent by the emergency service module is W1. If not, the vehicle position information sent is W2.

[0045] Specifically, after a vehicle collision accident causes the license plate body 1 to separate from the vehicle, if the distance between the final landing point of the license plate body 1 and the vehicle is large or the height difference is large (the specific difference range is adjusted according to actual conditions), if the license plate body 1 sends W2 at this time, it will easily lead to errors in the positioning of the subsequent emergency rescue part and reduce the efficiency of emergency rescue, so W1 needs to be sent.

[0046] The factor for considering height difference is mainly that the accident occurred in a valley. If the license plate body falls down the slope or into a ditch, even if the displacement value difference is small, the actual position information difference is large, so this factor needs to be considered.

[0047] In addition, when a vehicle is involved in a collision accident, if the license plate body 1 does not detach from the vehicle, but the vehicle moves by inertia due to the collision, resulting in a difference between the accident location and the final location of the vehicle, W2 needs to be sent to the emergency department.

[0048] In summary, this application uses the identification interaction module to assist the license plate in realizing near-field communication and reading its own related information, and uses the intelligent reminder module to deeply integrate with automobile after-sales service, insurance and other industries. This enables smart license plates to play a role in more fields, bringing new opportunities for the development of related industries, using encryption modules to ensure the security of license plate related information, using additional function modules to meet the diverse needs of users, allowing users to feel the convenience and value brought by smart license plates, and using emergency service modules to enable vehicles to provide accurate and effective positioning and achieve coordinated emergency treatment in the event of an emergency, thereby improving rescue efficiency.

[0049] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
