Description
Technical Field
The invention relates to a communication protocol of a vehicle networking, in particular to the technical field of configuration of vehicle-mounted equipment, and particularly relates to a configuration method for automatically binding a license plate and an equipment number.
Background
When the vehicle-mounted device is installed on a vehicle, the license plate number of the vehicle to which the vehicle-mounted device belongs is usually required to be set for the vehicle-mounted device to communicate with a remote server by taking the license plate number as an identification code, so that the network access of the vehicle-mounted device is realized. Since the vehicle-mounted equipment has a unique factory number (namely equipment number), the license plate number to which the vehicle-mounted equipment belongs is a license plate-equipment number binding process. The existing binding modes include three types: one is that the vehicle-mounted equipment provides screen display and key-press and other man-machine interaction modes, and a user sets a license plate number in a graphical interface of the vehicle-mounted equipment; the second type is that a network service, such as HTTP, SSH (Secure SHell, Secure SHell protocol) service, etc., is run on the vehicle-mounted device, and the user logs in a webpage of the vehicle-mounted device through a WIFI or ethernet interface and sets a license plate number by using a mobile phone APP or a network browser; the third type is that the user uses the terminal program to write the configuration file into the vehicle-mounted device. The three methods all require a user to set the vehicle-mounted equipment on site, and the workload of installing the equipment is increased.
When the mobile terminal accesses the telecommunication network, only the SIM card number is used as the identity identification, which is different from the identity authentication method for the network access of the vehicle-mounted equipment, so that the identity authentication problem of the network access of the vehicle-mounted equipment cannot be solved by using the authentication technology of the mobile terminal.
The network protocols include an ARP (Address Resolution Protocol) and an RARP (Reverse Address Resolution Protocol), which respectively handle the problem that the network terminal obtains a network card physical Address according to an IP Address and obtains an IP Address according to the network card physical Address.
However, since the vehicle-mounted device communicates with the server using the 3G/4G/5G network, the IP address is not fixed, and the identification code during network access is information such as a license plate number, which is different from a globally unique physical address configured when the network card leaves the factory, the binding between the device number and the license plate number cannot be realized using the ARP and RARP protocols.

It should be noted that the binding request and the binding information confirmation of the vehicle-mounted device can be implemented by using the same message, for example: when the vehicle-mounted equipment does not have the local configuration file, the information such as the license plate number is set to be a full zero value, and the second server B uniformly returns the complete information such as the factory serial number and the license plate number of the equipment. However, the server response message of this scheme is long, so the delay is long, and each time the information check is required by the in-vehicle device program, the calculation resources of the in-vehicle device are consumed more. Therefore, the embodiment of the invention adopts two types of messages to respectively process the binding request and the confirmation request.
In the embodiment of the present invention, except for the specific description of the model of each device, the model of other devices is not limited, as long as the device can perform the above functions.
