Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, which is a flowchart illustrating an embodiment of a communication method of a vehicle-mounted terminal according to the present invention, the method includes steps S1 to S3:
s1, receiving a message to be issued; the message to be issued at least comprises vehicle-mounted terminal information of the message to be received and issued;
s2, acquiring an authentication protocol of the vehicle-mounted terminal from a preset communication protocol list according to the message to be issued; the authentication protocol is a communication protocol which passes negotiation authentication between the vehicle-mounted system and the vehicle-mounted terminal, and the authentication protocol and the vehicle-mounted terminal are in one-to-one correspondence;
and S3, directly transmitting the message to be issued to the corresponding vehicle-mounted terminal according to the authentication protocol.
Specifically, the above steps are performed by a vehicle system of the vehicle. Generally, a car machine system acquires a message to be issued from a message center, that is, receives a message to be issued; the message to be issued at least comprises vehicle-mounted terminal information of the message to be received and issued. Generally, the in-vehicle terminal information is an ID of the in-vehicle terminal.
And acquiring the authentication protocol of the vehicle-mounted terminal from a preset communication protocol list according to the message to be issued, wherein the communication protocol list records the one-to-one correspondence relationship between the authentication protocol of the vehicle-mounted terminal and the ID, so that the corresponding authentication protocol of the vehicle-mounted terminal can be found from the communication protocol list. The authentication protocol is a communication protocol which passes negotiation authentication between the vehicle-mounted system and the vehicle-mounted terminal, and the authentication protocol corresponds to the vehicle-mounted terminal one to one.
And directly transmitting the message to be issued to the corresponding vehicle-mounted terminal according to the authentication protocol. After receiving the message to be issued, the vehicle-mounted terminal analyzes and identifies the message to be issued according to an authentication protocol stored in the vehicle-mounted terminal, and obtains the content of the message to be issued. In the message transmission process, the vehicle-mounted terminal and the vehicle-mounted terminal directly communicate through the authentication protocol without transmission through an intermediate medium of message routing, so that the message transmission efficiency is effectively improved.
In order to more clearly understand the implementation process of the present invention, a schematic flow diagram of another embodiment of a communication method of a vehicle-mounted terminal is further provided in the present invention, and refer to fig. 2.
According to the communication method of the vehicle-mounted terminal provided by the embodiment of the invention, the communication protocol list which can be directly communicated between the vehicle-mounted system and the vehicle-mounted terminal is generated through the pre-negotiation authentication of the vehicle-mounted system and the vehicle-mounted terminal, so that the problem of low transmission efficiency of a message route when a large amount of communication data is transmitted concurrently is effectively solved.
As an improvement of the above scheme, before the receiving the message to be sent, the method further includes:
receiving an instruction requesting to generate a communication protocol list, generating a communication negotiation instruction, and sending the communication negotiation instruction to each vehicle-mounted terminal through a message route; wherein the communication negotiation instruction comprises a plurality of different communication protocols;
receiving a negotiation authentication instruction returned by each vehicle-mounted terminal through the message route; the negotiation authentication instruction comprises an ID of a corresponding vehicle-mounted terminal and a communication protocol authenticated from the communication negotiation instruction;
and generating the preset communication protocol list according to the negotiation authentication instruction.
Specifically, before the in-vehicle system communicates with each vehicle-mounted terminal according to the authentication protocol, a communication protocol list needs to be established first, and this embodiment mainly describes a generation flow of the communication protocol list. After receiving the command requesting to generate the communication protocol list, the vehicle-mounted system generates a communication negotiation command and sends the communication negotiation command to each vehicle-mounted terminal through a message route; wherein the communication negotiation instruction comprises a plurality of different communication protocols.
And when the vehicle-mounted terminal receives the communication negotiation instruction, analyzing the communication negotiation instruction to obtain a plurality of communication protocols, and selecting one of the communication protocols as a communication protocol between the vehicle-mounted terminal and the vehicle-mounted machine system. And after the communication protocol is selected, packaging the communication protocol and the ID of the communication protocol and the ID to form a negotiation authentication instruction, and returning the negotiation authentication instruction to the vehicle-mounted machine system. That is to say, the vehicle-mounted terminal will respond to the communication negotiation command sent by the vehicle-mounted system, and generate a negotiation authentication command.
The vehicle-mounted terminal system receives a negotiation authentication instruction returned by each vehicle-mounted terminal through a message route; the negotiation authentication instruction comprises the ID of the corresponding vehicle-mounted terminal and the communication protocol authenticated from the communication negotiation instruction. And the communication protocol authenticated from the communication negotiation instruction is the authentication protocol corresponding to the vehicle-mounted terminal.
And generating a preset communication protocol list according to the negotiation authentication instruction. Because the negotiation authentication instruction comprises the ID and the authentication protocol of the vehicle-mounted terminal, the vehicle-mounted system can analyze and obtain the ID information and the authentication protocol corresponding to different vehicle-mounted terminals after receiving the negotiation authentication instruction fed back by all different vehicle-mounted terminals, simultaneously establish a communication protocol list, fill the ID information and the authentication protocol corresponding to all the vehicle-mounted terminals into the list, and generate the communication protocol list.
And after the communication protocol list is generated, all subsequent message transmission actions are directly sent to different vehicle-mounted terminals by the vehicle-mounted system through the authentication protocol.
As an improvement of the above scheme, the method further comprises:
receiving an instruction requesting to verify a communication protocol list, generating a verification instruction, and sending the verification instruction to each vehicle-mounted terminal according to the communication protocol list; the verification instruction comprises verification information and authentication protocols of all vehicle-mounted terminals;
receiving a feedback instruction returned by the vehicle-mounted terminal according to the corresponding authentication protocol; the feedback instruction comprises feedback information of the vehicle-mounted terminal responding to the verification information;
judging whether an unrevealed vehicle-mounted terminal exists in a preset time period or not;
and when the vehicle-mounted terminal which is not fed back exists, updating the preset communication protocol list.
Specifically, in order to verify the feasibility of the communication protocol list, the embodiment of the present invention also verifies the communication protocol list, and the verification process is performed by using an authentication protocol, so that the rate of data transmission can be further increased without using message routing. That is to say, after the communication protocol list is generated, if the authentication protocol of the vehicle-mounted terminal changes, the verification can be performed through the following steps, and when the verification is abnormal, the list is updated through the message route without updating through the message route every time, so that the data transmission rate is effectively improved.
The vehicle-mounted terminal generates a verification instruction after receiving the instruction requesting verification of the communication protocol list, and sends the verification instruction to each vehicle-mounted terminal according to the communication protocol list; the verification instruction comprises verification information and authentication protocols of all vehicle-mounted terminals. The specific content of the verification information may be changed or modified according to the actual application requirement, and is not limited herein.
And after receiving the verification instruction, the vehicle-mounted terminal responds to the verification instruction to generate a feedback instruction and sends the feedback instruction to the vehicle-mounted system.
The vehicle-mounted terminal receives a feedback instruction returned by the vehicle-mounted terminal according to the corresponding authentication protocol; and the feedback instruction comprises feedback information of the vehicle-mounted terminal responding to the verification information. The specific content of the feedback information may be changed or modified according to the actual application requirement, and is not limited herein.
And judging whether the vehicle-mounted terminal which is not fed back exists in a preset time period. Under the normal condition, in the preset time quantum, the vehicle-mounted machine system can receive the feedback instructions of all the vehicle-mounted terminals, when the abnormality occurs, the vehicle-mounted machine system cannot receive the feedback instructions of all the vehicle-mounted terminals, and the vehicle-mounted terminals without feedback can be identified. The in-vehicle terminal having no feedback information generally transmits a changed in-vehicle terminal for a newly added in-vehicle terminal or a communication protocol.
When there is an unreeeded vehicle-mounted terminal, the vehicle-mounted system needs to repeatedly execute the steps of the second embodiment on the vehicle-mounted terminal, that is, send a communication negotiation instruction to the vehicle-mounted terminal through a message route, receive a negotiation authentication instruction returned by the vehicle-mounted terminal through the message route, update the ID of the vehicle-mounted terminal and a new authentication protocol included in the negotiation authentication instruction into an original communication protocol list, and update a preset communication protocol list.
As an improvement of the above scheme, after the receiving of the feedback instruction returned by the vehicle-mounted terminal according to the corresponding authentication protocol, the method further includes:
judging whether feedback information in the feedback instruction is abnormal or not;
and when the feedback information is abnormal, updating the preset communication protocol list.
Specifically, even if the in-vehicle system can receive the feedback instructions of all the vehicle-mounted terminals, the communication between the in-vehicle system and the vehicle-mounted terminals still may have risks, and in order to deepen the reliability of the communication, the embodiment of the invention also verifies the feedback instructions and judges whether the feedback information in the feedback instructions is abnormal.
Generally, the vehicle-mounted terminal system presets verification information and corresponding feedback information, and sends the feedback information to each vehicle-mounted terminal for storage. When the vehicle-mounted terminal receives the verification instruction, the verification information can be obtained through analysis, then the corresponding feedback information stored by the vehicle-mounted terminal is obtained according to the verification information, the feedback information is returned to the vehicle-mounted system, and the vehicle-mounted system can compare whether the received feedback information is consistent with the preset feedback information or not, so that whether the feedback information of the vehicle-mounted terminal is abnormal or not is judged.
When the feedback information is abnormal, the vehicle-mounted terminal is considered to be abnormal in state, protocol negotiation needs to be carried out again, and a preset communication protocol list is updated. And when the feedback information is not abnormal, the communication between the vehicle-mounted terminal system and the corresponding vehicle-mounted terminal is considered to be reliable, and a preset communication protocol list does not need to be updated.
As an improvement of the above scheme, the method further comprises:
and when detecting that a new vehicle-mounted terminal appears, updating the preset communication protocol list.
Specifically, when the new vehicle-mounted terminal is detected to appear, the preset communication protocol list is updated. In this case, when the in-vehicle device system accesses a new in-vehicle terminal and the communication protocol list is not verified yet, and the new in-vehicle terminal is detected, the in-vehicle terminal may be directly negotiated and authenticated.
In the negotiation authentication process, the in-vehicle system needs to repeatedly execute the steps of the second embodiment on the vehicle-mounted terminal, that is, send a communication negotiation instruction to the vehicle-mounted terminal through the message routing, receive the negotiation authentication instruction returned by the vehicle-mounted terminal through the message routing, add the ID and the authentication protocol of the vehicle-mounted terminal included in the negotiation authentication instruction to the original communication protocol list, and update the preset communication protocol list.
