It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, an embodiment of the present invention provides a method for communication matching with a coprocessor, including the steps of:
and S1, reading the first client attribute in the system attributes.
In step S1, the system attribute is an attribute of the vehicle-mounted host system, which may include information such as a version number of the vehicle-mounted host system. The first customer attribute is an attribute representing the current vehicle-mounted system user, and the current vehicle-mounted system user is a generator combining the vehicle-mounted main system and the coprocessor together.
S2, searching a first communication protocol corresponding to the first client attribute in a mapping list of the preset client attribute and the communication protocol.
In step S2, the mapping list of the client attribute and the communication protocol is a list that is installed in the vehicle-mounted main system by the vehicle-mounted main system provider in advance, and the vehicle-mounted main system provider knows the coprocessors used by different clients in advance, so that the generation of the mapping list of the client attribute and the communication protocol can be completed. The mapping list may be that a plurality of client attributes correspond to the same communication protocol, or that a plurality of communication protocols correspond to the same client attribute. In this embodiment, the client attribute is a unique number ID representing a client, that is, each client corresponds to a unique ID number, and as long as the unique number ID is known, the client can be determined, and thus which coprocessor the vehicle-mounted host system is to be in communication connection with is determined.
And S3, calling the first communication protocol to communicate with the coprocessor.
In step S3, the in-vehicle main system calls the first communication protocol matched by the first client attribute, and thus, the communication with the coprocessor is completed.
Referring to fig. 2, in this embodiment, before the step S1 of reading the first client attribute in the system attributes of the vehicle-mounted host system, the method includes:
s101, receiving a first customer attribute, and adding the first customer attribute to the system attribute.
In step S101, after the vehicle-mounted main system provider knows that the vehicle-mounted main system is to be provided to the first customer, it is not necessary to input or update a communication protocol in the vehicle-mounted main system for the first customer, so as to ensure that the vehicle-mounted main system and the coprocessor of the first customer can be in communication connection, and it is only necessary for the user to input the first customer attribute through the display screen, thereby implementing that the first customer attribute corresponding to the first customer is added in the system attribute of the vehicle-mounted main system, which is simple and convenient, and reduces the workload of the vehicle-mounted main system provider.
In this embodiment, after the step S3 of invoking the first communication protocol to communicate with the coprocessor, the method includes:
and S40, judging whether the communication between the vehicle-mounted main system and the coprocessor is successful.
In step S40, there are many methods for determining whether the communication between the vehicle-mounted main system and the coprocessor is successful, for example, the vehicle-mounted main system sends a search signal to the coprocessor, then waits for a feedback signal from the coprocessor, and if the feedback is out of time, it may be determined that the communication between the vehicle-mounted main system and the coprocessor is failed, and if the normal feedback signal is waited within a specified time, it is determined that the communication between the vehicle-mounted main system and the coprocessor is successful. And knowing whether the communication between the vehicle-mounted main system and the coprocessor is successful, so as to conveniently perform corresponding operation according to the communication condition, for example, if the communication condition is successful, a corresponding coprocessing task can be completed through the coprocessor.
And S50, if the communication fails, executing the preset action.
In step S50, the communication failure executes a preset action, which may be a prompt message, so that the user can know the problem of the vehicle-mounted system in time, and can process the problem in time, or other matching actions.
In this embodiment, the step S50 of executing the preset action includes:
s51, generating reminding characters to be displayed on a display screen of the vehicle-mounted main system; or,
and S52, generating a reminding voice for the loudspeaker to play.
In the step S51, the reminder information is text and is displayed on the display screen of the vehicle-mounted host system, so that the user can use the reminder information to view the reminder information visually; in the step S52, the generated reminding voice is played through the speaker of the vehicle-mounted main system, so that the user can hear the reminding voice to know the communication failure through hearing, and the probability that the user finds the communication failure in time is improved.
In this embodiment, the steps S51 and S52 may be performed simultaneously, so as to improve the probability that the user finds the communication failure in time.
In another embodiment, the step S50 of executing the preset action includes:
and S53, sending matching failure information and reason information corresponding to the matching failure to the terminal.
In step S53, the information of the reason for the matching failure includes a communication protocol matching error, an error in a serial port connecting the vehicle-mounted main system and the coprocessor, and the like. The terminal can be a terminal of a vehicle-mounted system provider, after the vehicle-mounted main system provider receives the matching failure information and the reason information thereof, the matching failure information can be processed at the first time and fed back to the terminal of the client corresponding to the first client attribute, the client does not need to report, the response speed is higher, the completion speed of the solution is further improved, the working efficiency is improved, and the user experience is improved.
In another embodiment, the step S50 of executing the preset action includes:
s54, calling a plurality of preset second communication protocols one by one to respectively communicate with the coprocessor;
s55, monitoring whether the second communication protocol called currently is successfully communicated with the coprocessor;
and S56, if the communication is successful, selecting the current second communication protocol as the communication protocol of the main processor and the coprocessor.
In the above steps S54, S55, and S56, the plurality of second communication protocols are typically other communication protocols than the first communication protocol described in the mapping list of the client attribute and the communication protocol. In this embodiment, that is, the vehicle-mounted main system uses one communication protocol of the plurality of second communication protocols one by one to perform communication connection with the coprocessor, when the vehicle-mounted main system monitors that the communication with the coprocessor is successful, it is determined that the currently used second communication protocol is the communication protocol matched with the vehicle-mounted main system and the coprocessor, that is, it is determined that the current second communication protocol is used as the communication protocol of the main processor and the coprocessor, and in the future communication process, the current second communication protocol is directly called to be used. In a subsequent step, the other second communication protocol and the first communication protocol may also be deleted.
