Detailed Description
With the above figures, certain embodiments of the invention have been illustrated and described in more detail below. The drawings and the description are not intended to limit the scope of the inventive concept in any way, but rather to illustrate it by those skilled in the art with reference to specific embodiments.
Fig. 1 is a schematic view of an application scenario of a vehicle-mounted device communication method according to an embodiment of the present invention, and as shown in fig. 1, the application scenario of the vehicle-mounted device communication method includes a vehicle-mounted device 101 and a terminal 102, where the vehicle-mounted device 101 is an automobile with an intelligent internet function, and the terminal 102 is an intelligent terminal such as an intelligent player, an air humidifier, an intelligent rearview mirror, a vehicle-mounted refrigerator, or a vehicle-mounted massager. The car machine 101 and the terminal 102 are connected via a Universal Serial Bus (USB), bluetooth, Wireless-Fidelity (WIFI) or a Bus. The data communication is established between the car machine 101 and the terminal 102 through different connection modes, so that the purpose that the terminal 102 with different functions provides various application functions for the car machine 101 is achieved, and the comfort of driving a car and the intelligent control of the car are greatly improved.
When the terminal 102 establishes a connection with the car machine 101, the terminal 102 and the car machine 101 complete data communication through a physical layer, a protocol layer and an application layer in each communication mode. For example, when the terminal 102 is a vehicle-mounted refrigerator, the terminal 102 and the vehicle machine 101 are connected through a bus, the terminal 102 completes data communication through a physical layer, a protocol layer and an application layer in the bus communication, and the vehicle machine 101 realizes intelligent control over the terminal 102 through the physical layer, the protocol layer and the application layer of the bus communication. However, the types of the terminals 102 are various, and the connection modes between the terminals 102 with different function types and the car machine 101 are also different. Therefore, the car machine 101 needs to configure a plurality of communication protocols. The configuration of multiple communication protocols on the car machine 101 not only has the problem of high development cost, but also has the problems of low development efficiency and difficult realization of new and old versions of communication protocols due to continuous updating and upgrading of the terminal 102.
In order to solve the technical problems, the vehicle-mounted device communication method based on the scene is improved, a unified protocol layer is developed on the basis of data communication of different physical layers when the terminal 102 is connected with the vehicle-mounted device 102, and a unified data communication mode is configured on the protocol layer so as to realize a unified data communication mode between the vehicle-mounted device 101 and different terminals 102.
Fig. 2 is a first flowchart of a vehicle-mounted device communication method according to an embodiment of the present invention. The execution subject of the method of this embodiment may be the car machine in fig. 1. As shown in fig. 2, the vehicle-mounted device communication method includes the following steps:

When a terminal accesses a car machine, the car machine needs to verify whether the terminal passes authentication before the access. If the terminal passes the authentication, the repeated authentication is not needed, the data communication can be directly carried out after the terminal is connected to the vehicle machine, if the authentication does not pass, the authentication is firstly needed, and after the authentication is successful, the data communication can be established between the terminal and the vehicle machine. The vehicle machine receives the check data frame sent by the terminal through the vehicle machine protocol layer to verify whether the terminal passes the authentication.
As shown in table 1, the car machine parses the check data frame according to the data frame format of the protocol set in tables 1 and 2, and obtains the terminal identifier, the verification token, and the control information. Wherein, the flag bit of the response frame in the check data frame is 0, the flag bit of the direction is 1, and the message type is 2. The verification data frame is an active frame which is actively sent to the vehicle machine by the terminal, and the content contained in the verification data frame is terminal identification, a verification token and control information.
TABLE 1 data frame Format
TABLE 2 message types
The data frame in table 1 defines a format of a communication data frame between a terminal protocol layer and a vehicle protocol layer, and includes a frame header, a length, a terminal type, a terminal identifier, a frame number, a message type, a validation token, a control information length, a control information, a checksum, and a frame trailer. Specific contents of the message type format are defined in table 2, for example, a flag bit of the response frame is defined, when the flag bit of the response frame is 0, the data frame is represented as an active frame, and when the flag bit of the response frame is 1, the data frame is represented as a response frame; a direction flag bit is further defined, when the direction flag bit is 0, the data frame is sent to the car machine by the terminal, and when the direction flag bit is 1, the data frame is sent to the terminal by the car machine; the specific content of the message type is also defined, when the message type is 0, the data frame is used for authentication, when the message type is 1, the data frame is shown to contain wireless network information of a terminal access vehicle machine, and when the message type is 2, the data frame is shown to be used for transmitting data.
S22: and verifying according to the verification token and the terminal identification in the vehicle machine protocol layer.
And in the vehicle machine protocol layer, verifying whether the terminal passes the authentication according to the obtained verification token and the terminal identification. And verifying whether the verification token corresponds to the terminal identification or not, and verifying whether information consistent with the verification token and the terminal identification exists in the vehicle machine or not.
S23: and if the verification result is successful, sending the control information to the vehicle machine application layer through the vehicle machine protocol layer.
If the verification token is consistent with the terminal identification, and the verification token and the terminal identification are also consistent with the verification token and the terminal identification stored in the vehicle, the verification result is successful, which indicates that the terminal passes the authentication before accessing the vehicle at this time, the terminal can directly perform data communication with the vehicle, and transmits control information to a vehicle application layer through a vehicle protocol layer, wherein the control information comprises corresponding intelligent networking application and application configuration information when the terminal accesses the vehicle.
S24: and communicating with the terminal at the vehicle application layer according to the control information.
And the application in the vehicle machine application layer establishes data communication connection with the terminal according to the control information. For example, when the terminal is an intelligent rearview mirror, the multimedia control screen in the vehicle machine performs data communication with the intelligent rearview mirror through the information of the intelligent rearview mirror configured in the control information. For example, the reverse information transmitted by the intelligent rearview mirror in real time is acquired, or the reverse control information sent by the intelligent rearview mirror according to the information behind the vehicle is received.
It can be seen from the foregoing embodiment that, when the terminal accesses the car machine, the check data frame is analyzed by the car machine protocol layer to obtain the terminal identifier, the verification token, and the control information, and if it is determined that the terminal has passed the authentication, the car machine application layer establishes data communication with the terminal according to the control information. The embodiment of the invention realizes a unified data communication mode between the vehicle machine and different terminals by providing a unified terminal access method and configuring a unified data processing flow at a protocol layer. The problem that the development cost of configuring various communication protocols on the vehicle is high is solved, and the problems of low development efficiency and difficulty in implementation of the communication protocols are also solved.
Fig. 3 is a flowchart of a vehicle-mounted device communication method according to an embodiment of the present invention. The execution subject of the method of the embodiment may be the terminal in fig. 1. As shown in fig. 3, the vehicle-mounted device communication method includes the following steps:

S32: and when the connection with the vehicle machine is detected, detecting whether an authentication result is stored and judging whether the authentication result passes the authentication.
When the terminal is detected to be connected with the vehicle machine and start communication, whether an authentication result is stored in the terminal or not is detected, and whether the authentication result passes the authentication or not is judged. If the terminal passes the authentication before accessing the car machine, and the authentication result is that the authentication is successful, the terminal passes the authentication. If the authentication result is not stored in the terminal or the stored authentication result fails to authenticate, it indicates that the terminal has not authenticated or failed to authenticate before.
S33: and if the authentication result is stored and the authentication result is authenticated, initiating a communication request through a terminal application layer and generating a verification data frame according to a set protocol in a terminal protocol layer, wherein the verification data frame comprises a terminal identifier, a stored verification token and control information.
If the terminal is detected to store the authentication result and the stored authentication result is successful, only the terminal passes the authentication and is successfully authenticated before being accessed into the vehicle machine, and the terminal cannot be proved to be connected with the vehicle machine. Therefore, in order to check whether the connection is established with the vehicle machine, the application layer of the terminal initiates a communication request, and generates a check data frame in the protocol layer of the terminal according to a data frame format with a protocol, wherein the check data frame comprises a terminal identifier, and an authentication token and communication control information which are stored in the terminal.
S34: and sending the check data frame to the vehicle machine through a terminal protocol layer.
And the terminal sends the verification data frame to the vehicle machine through the protocol layer so that the vehicle machine verifies whether the terminal is connected with the vehicle machine according to the authentication result in the verification data frame.
It can be known from the foregoing embodiment that, when the terminal is powered on and started, the communication data of the terminal protocol layer is configured through the terminal application layer, so that the protocol layer of the terminal establishes a connection with the car machine according to the configured communication data. Before the terminal is connected with the vehicle machine, whether the terminal passes the authentication before the access is judged by detecting whether the authentication result and the authentication content are stored in the terminal, and whether the connection with the equipment is established is verified according to the verification token and the terminal identification, so that the processing flow of the terminal accessing the vehicle machine is simplified, and the efficiency of establishing communication between the vehicle machine and the terminal is improved.

As shown in fig. 4, the vehicle-mounted device communication method includes the following steps:

S42: when the terminal detects that the terminal is connected with the car machine, whether an authentication result is stored or not is detected, and whether the authentication result passes the authentication or not is judged.
S43: and if the authentication result is stored and the authentication result is authenticated, the terminal initiates a communication request through a terminal application layer and generates a verification data frame according to a set protocol on a terminal protocol layer, wherein the verification data frame comprises a terminal identifier, a stored verification token and control information.
S44: and the terminal sends the check data frame to the vehicle machine through a terminal protocol layer.

S46: and the vehicle machine checks according to the verification token and the terminal identification in a vehicle machine protocol layer.
S47: and if the verification result is successful, the vehicle machine sends the control information to the vehicle machine application layer through the vehicle machine protocol layer.
S48: and the vehicle machine communicates with the terminal according to the control information at the vehicle machine application layer.
S41 to S44 are similar to S31 to S34 in the embodiment of fig. 3, and S45 to S48 are similar to S21 to S24 in the embodiment of fig. 2, which is not limited herein.

As shown in fig. 5, when the terminal establishes a connection with the car machine, a control access channel is established between a protocol layer of the terminal and a protocol layer of the car machine for authentication of the terminal and transmission of control information between the terminal protocol layer and the car machine protocol layer, where the control information includes transmission parameters between the terminal protocol layer and the car machine protocol layer and transmission parameters of a communication protocol between an application layer of the terminal and the car machine application layer. By providing a uniform control access channel between the protocol layer of the terminal and the protocol layer of the vehicle, the user-defined transmission protocol between the application layer of the terminal and the application layer of the vehicle is set, the security of key sensitive data is ensured, and the unification of the connection standard when the terminal is connected with the vehicle is realized.
As shown in fig. 5, a data flow channel is established between the application layer of the terminal and the application layer of the car machine, and is used for transmitting specific data between the terminal protocol layer and the car machine protocol layer through the device, for example, when the terminal is an intelligent rearview mirror, the terminal application layer transmits video data acquired in real time when the car is backed up to the car machine through the data flow channel. And enabling the data stream channel only after the terminal passes the authentication, determining the network interconnection protocol of the data stream channel by the control information transmitted in the control access channel, and determining when to initiate data transmission in which data format according to the content of the network interconnection protocol customized in the control information.
