Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1
Referring to fig. 1, fig. 1 is a flowchart of a method for synchronizing version information of vehicle-mounted software according to an embodiment of the present invention; comprising the following steps:
s1, monitoring a software refreshing event generated by updating vehicle-mounted software of a vehicle by external terminal equipment; the external terminal device is used for locally updating the vehicle-mounted software of the vehicle through a vehicle-mounted software updating program stored in advance;
s2, responding to the monitoring of the software refreshing event, and acquiring the version information of the vehicle-mounted software updated by the external terminal equipment;
and S3, uploading the version information of the vehicle-mounted software to a server for storage.
It should be noted that, the method for synchronizing version information of vehicle-mounted software in the embodiment of the invention can be implemented by a vehicle-mounted terminal in a vehicle, wherein the vehicle-mounted terminal is front-end equipment of a vehicle monitoring management system, integrates multiple functions such as data processing and data communication, and has a powerful service scheduling function and data processing capability. The external terminal device may be an automotive diagnostic instrument or other device capable of updating on-board software in the vehicle.
When the external terminal equipment locally updates the vehicle-mounted software in the vehicle, the vehicle-mounted terminal responds to a software refreshing event generated by the external terminal equipment for updating the vehicle-mounted software of the vehicle, at the moment, the vehicle-mounted terminal acquires the vehicle-mounted software version information updated by the external terminal equipment, and finally, the vehicle-mounted software version information is uploaded to a server for storage, so that the server can timely synchronize the vehicle-mounted software version information. According to the embodiment of the invention, when the server needs to synchronize the version information of the vehicle-mounted software, the version information of the vehicle-mounted software does not need to be periodically queried, but the corresponding version information of the vehicle-mounted software is directly acquired when the vehicle-mounted software is updated, so that the resources for transmitting and receiving the information of the vehicle-mounted terminal are not occupied too much, and the network flow is saved.
Specifically, in step S1, the monitoring the software refreshing event generated by the update of the vehicle software of the vehicle by the external terminal device includes:
s11, monitoring an operation message in a vehicle-mounted network; the operation message is generated by the vehicle when the external terminal equipment operates the vehicle;
and S12, when the operation message is monitored and the message carrying the software refreshing event identification code is detected, judging that the occurrence of the software refreshing event is monitored.
Specifically, when the vehicle has the vehicle-mounted software in the vehicle and is updated, the vehicle generates a message carrying the software refreshing event identification code, so that whether the occurrence of the software refreshing event is monitored can be determined by monitoring the operation message in the vehicle-mounted network.
Preferably, after the operation message in the vehicle-mounted network is monitored, before the operation message is monitored and the operation message is detected to carry the software refreshing event identification code, the method further includes: when the operation message is monitored and the head in the message is detected to carry a diagnosis message identification code, judging the current message as a diagnosis message; at this time, it is considered that a diagnostic instrument operation event is detected, that is, the external terminal device is operating the in-vehicle ECU. Step S12 specifically includes: and when the diagnosis message is detected to carry the software refreshing event identification code, judging that the occurrence of the software refreshing event is monitored. Preferably, the vehicle-mounted network and the vehicle-mounted terminal communicate by adopting a UDS protocol, and the identification code of the diagnosis message is 7 or 1. Of course, the diagnostic message identifier may be other values, which are not described in detail herein.
After the current message is determined to be a diagnostic message, since the diagnostic message covers a conventional diagnostic event and a software refreshing event, it is necessary to further determine whether the diagnostic message indicates the occurrence of the software refreshing event. At this time, whether the occurrence of the software refreshing event is monitored is determined by judging whether the operation message carries the software refreshing event identification code. Preferably, the software refresh event identification code is "6EF1 84", that is, the operation message may be "7XX XX 6E F1 84XX XX XX XX". It should be noted that, the software refreshing event identification code may be replaced by other identification codes in the software refreshing process, and the software refreshing event identification code may also be set to other values, so long as the software refreshing event can be uniquely identified, which is within the protection scope of the present invention.
Specifically, in step S2, the responding to the monitoring of the software refreshing event, obtaining the vehicle software version information updated by the external terminal device for the vehicle software, includes:
s21, in response to the detection of the software refreshing event, uploading update identification information corresponding to the software refreshing event to the server;
s22, receiving a software version information acquisition instruction sent by the server according to the update identification information, and acquiring vehicle-mounted software version information updated by the external terminal equipment on the vehicle-mounted software according to the software version information acquisition instruction.
Preferably, the vehicle-mounted software is ECU software, and the updated identification information is an identification code of an ECU updated by the vehicle-mounted ECU on the vehicle. Further, the identification code of the ECU updated by the vehicle software may be the identification code of the ECU carried in the operation message, for example, the identification code of the ECU is "7XX" in the operation message. Referring to table 1, table 1 is a format definition for the software refresh event.

| 1 | Event number ID, fill 1 |
| 1 | Number of ECUs |
| 1 | ECU coding 1 |
| … | …… |
| 1 | ECU encodes n |
Preferably, step S21 specifically includes:
s211, responding to the monitoring of the software refreshing event, taking a preset mark position as a first value, and acquiring and storing update identification information corresponding to the software refreshing event;
and S212, in response to the fact that the mark position is detected to be a first value, uploading updated identification information corresponding to the software refreshing event to the server, and enabling the mark position to be a second value.
Specifically, the flag bit is flag, the first value is 1, and the second value is 0. When the software refreshing event is responded and monitored, setting the flag to be 1, and acquiring and storing update identification information corresponding to the software refreshing event; and in response to the fact that the flag is 1, uploading updated identification information corresponding to the software refreshing event to the server, and setting the flag to 0.
In this embodiment, after the software refreshing event is monitored, by acquiring and storing the corresponding update identification information and setting the flag position to the first value, even if an accident occurs to the vehicle (for example, the vehicle cannot be normally connected with the server at present, or the vehicle is abnormally powered down, etc.), after the vehicle is recovered to be normal, the user can immediately respond to the monitoring that the flag position is the first value and upload the update identification information corresponding to the software refreshing event to the server in time, so that the server can be effectively ensured to update the updated version information of the vehicle-mounted software synchronously.
Preferably, the timing of detecting the flag bit is set as follows: when the whole car is electrified. Specifically, in view of real-time performance, the update identification information may be immediately uploaded to the server after the update identification information is acquired. However, the traffic is used every time the connection between the vehicle-mounted terminal and the server is established, if the updated identification information is immediately uploaded to the server after the vehicle-mounted terminal acquires the updated identification information, the connection between the vehicle-mounted terminal and the server needs to be established for a plurality of times, and the traffic of the vehicle-mounted terminal is wasted. Therefore, in order to achieve the purpose of saving current, the update identification information can be sent to the server only when the whole vehicle is electrified, and the national standard data are required to be uploaded to the server when the vehicle is electrified and started each time, so that the update identification information can be uploaded to the server while the international data are uploaded, and the traffic of the vehicle is saved.
When the whole vehicle is powered on, monitoring the marker bit, and when the marker bit is a first value, indicating that a software refreshing event occurs before the whole vehicle is powered on, and uploading update identification information corresponding to the software refreshing event to the server; and when the mark position is a second value, the fact that a software refreshing event does not occur before the whole vehicle is powered on is indicated.
Preferably, the timing of setting the flag position to the second value is set as: and when receiving a response instruction returned by the server according to the received updated identification information. And after receiving the updated identification information, the server returns a response instruction, and when receiving the response instruction, the server sets the mark position as a second value.
Further, the process of steps S1 to S2 may refer to fig. 2.
Specifically, in step S3, the version information of the vehicle-mounted software is uploaded to a server for storage, so that the server synchronously updates the version information of the vehicle-mounted software in the database. Further, the vehicle-mounted software version information can be uploaded to a server, and meanwhile, the vehicle-mounted software upgrading package corresponding to the vehicle-mounted software version information can be uploaded together, so that the server can update the vehicle-mounted software upgrading package in the database together. Then step S2 is: when the software refreshing event is responded, acquiring the vehicle-mounted software version information updated by the external terminal equipment on the vehicle-mounted software and a vehicle-mounted software upgrading packet corresponding to the vehicle-mounted software version information; the step S3 is as follows: uploading the version information of the vehicle-mounted software and the upgrading package of the vehicle-mounted software to a server for storage.
Compared with the prior art, the vehicle-mounted software version information synchronization method disclosed by the embodiment of the invention is characterized in that firstly, a software refreshing event generated by updating the vehicle-mounted software of the vehicle by the external terminal equipment is monitored; and then, when the software refreshing event is monitored, acquiring the vehicle-mounted software version information updated by the external terminal equipment on the vehicle-mounted software, so that the vehicle-mounted software version information does not need to be periodically queried when the server needs to synchronize the vehicle-mounted software version information, and finally, uploading the vehicle-mounted software version information to the server for storage, so that the server can timely synchronize the vehicle-mounted software version information. According to the embodiment of the invention, when the server needs to synchronize the version information of the vehicle-mounted software, the version information of the vehicle-mounted software is not required to be periodically queried, but the corresponding version information of the vehicle-mounted software is directly acquired and uploaded to the server in time when the vehicle-mounted software is updated, the version information of each vehicle-mounted software on the vehicle is not required to be periodically read by the vehicle-mounted terminal, the influence on the vehicle-mounted network caused by the periodic reading of the version information by the vehicle-mounted terminal is avoided, the resources for transmitting and receiving the information by the vehicle-mounted terminal are not required to be excessively occupied, and the network flow is saved.
