2. The system of claim 1,
the vehicle-mounted system is also used for acquiring vehicle connection card information of the vehicle terminal and sending a number taking request to an authentication and verification server through an Internet of things gateway, wherein the number taking request carries the vehicle connection card information of the vehicle terminal prefabricated by the Internet of things gateway and the vehicle connection card information acquired by the vehicle-mounted system;
accordingly, the system further comprises:
the authentication and verification server is used for performing consistency authentication on the vehicle connection card information in the number taking request and the vehicle connection card information acquired by the vehicle-mounted system;
and the vehicle-mounted system is also used for initiating an uplink request after the consistency authentication result is passed.
3. The system of claim 2, wherein the vehicle-mounted terminal comprises a signal acquisition device and a wireless transmitter, and the vehicle-mounted system comprises a wireless receiver and a uplink processing platform, wherein:
the signal acquisition device is used for acquiring vehicle information needing to be updated of a vehicle and sending the vehicle information to the vehicle-mounted system through the wireless transmitter; and the vehicle-mounted system receives the vehicle information through a wireless receiver and transmits the vehicle information to the uplink processing platform for storage before sending the number taking request.
4. The system of claim 1,
the vehicle-mounted system is also used for encrypting the vehicle information by using the secret key information of the vehicle terminal and performing signature processing by using the certificate secret key of the vehicle terminal before initiating the uplink request;
and the MEC server is also used for adopting the certificate public key of the vehicle terminal to carry out signature verification processing on the certificate private key and verifying whether the vehicle terminal is in an access permission white list.
5. The system of claim 4,
the MEC server is also used for acquiring certificate application information sent by a vehicle terminal, wherein the certificate application information at least comprises a vehicle running certificate, a driving certificate of a vehicle owner and identity information; and sending the certificate application information to a certificate authority for authentication, and if the certificate application information is legal, sending a certificate issuing request to a certificate issuing organization to issue a signature certificate and secret key information to the vehicle terminal.
6. The system of claim 4,
the vehicle-mounted system is further used for sending a number fetching request to the authentication and verification server through the internet of things gateway again when the vehicle terminal passes the verification;
and the authentication and verification server is also used for performing consistency authentication on the vehicle connection card information in the number obtaining request and the vehicle connection card information in the uplink data submitted by the vehicle-mounted system.
7. The system of claim 6,
the MEC server is further used for executing an intelligent contract when the vehicle terminal passes the verification, the intelligent contract is used for triggering the vehicle-mounted system to send a number taking request with the vehicle connection card data flow to the Internet of things gateway, the Internet of things gateway identifies the vehicle connection card information and inserts the vehicle connection card information into a number taking request message, and the MEC server is further used for triggering the uplink data submitted by the vehicle-mounted system to be inserted into a number taking request message corresponding to the number taking request provided by the Internet of things gateway and transmitting the uplink data to the authentication verification server.
8. The system of claim 6,
and the MEC server receives the verification result returned by the authentication verification server, updates the block chain block information if the verification result is passed and the vehicle information passes the consensus, and synchronizes the vehicle information to the local storage center of the MEC server.
9. The system of claim 1, further comprising:
and the MCE edge cloud platform is used for pushing the vehicle information to other covered vehicle terminals.
10. A vehicle information sharing method based on a block chain is characterized in that block chain link points are deployed in an MEC server, and the method comprises the following steps:
the vehicle terminal collects vehicle information to be shared;
the vehicle-mounted system initiates a uplink request to the MEC server, wherein the uplink request is used for requesting to submit the vehicle information to uplink;
and the MEC server performs consensus verification on the uplink request, and responds to the uplink request to submit the vehicle information to uplink when the result of the consensus verification is passed.
