The Channel module in the IVI is responsible for communicating with a server and an Mtkproxy of the IVI, the LogManager is responsible for capturing the IVI or the IC or all logs, the logs are stored in the EMMC in real time through the LogCache in the instrument and are extracted by the LogManager, the Update is responsible for updating the debugged program to the system IVI, the UpdateIC is an updating IC, and all logic processing is completed in the ProcessCore.
The remote end is deployed in a server Docker container inside an enterprise and is forwarded to the outside through gateway mapping, a human-computer interaction interface is provided, an operator can select a machine to be remotely assisted (identified by a VIN code), and the remote end operation process is as shown in FIG. 2.
step 1: in the implementation, after the feedback from the vehicle end is received on line (the version number of the equipment needs to be informed to the far end), the far end can actively initiate a command for collecting the vehicle log, the far end has a special background manager to process the request in real time, and each assisting process has a unique operationid.
Step2 and step7 communicate with the IVI end through a socket, and the command data structure is as follows (JAVA implementation):
step 3: the Channel module in fig. 1 starts a service to monitor an 8081 port of a server all the time, receives and analyzes data and transmits the data to a ProcessCore module, and processes a step of capturing a log in the ProcessCore, as shown in fig. 4, a log device id to be captured is obtained according to a detail field in the data, wherein S401, S402, and S403 call api of LogManager to execute, and the log is captured and packaged into a tar file and then calls the Channel to upload to a server.
step 4: after the logs are uploaded successfully, the background management personnel can download the logs to corresponding development, step1, step2 and step3 are not limited to operation by the background management personnel, and can also be operation by the development personnel.
step5 is the flow of the developer's normal analysis to solve the problem, and if the problem can be solved directly from the log, without confirmation and timely solution, the solution can be directly considered to end the assistance.
To accomplish this function, the present invention defines a rule for making a file-based debug package, the content of the debug package is shown in fig. 3, the content in the debug package is an update file and a configuration description of the system to be debugged, and the implementation only includes IVI and meters, but is not limited thereto. Xml file is described as follows, the name value in data is the file name in the compressed package, the path value is the absolute path of the file in the system, and the debug package name is named with vin + operation + timestamp.
<config version＝"1.0">
< | A! -sign of whether to restore the system after solving the problem >
<rollback value＝"true">
<data name＝"file1"path＝""/>
<data name＝"file2"path＝""/>
......
</config>
After the debugging package is manufactured, the debugging package can be uploaded through a human-computer interface of the server, and the operationid corresponding to the debugging package is bound.
step 7: an entry assist debug command is sent.
step8, after the vehicle end receives the debugging assisting command, the vehicle end can enter the debugging mode to prompt the user that the vehicle can not run when the vehicle speed is equal to 0, the specific steps are as shown in figure 5, after the download address of the debugging package in the detail in the debugging assisting command is analyzed, the debugging package is downloaded, after decompression, the IC or IVI is respectively subjected to Update operation according to the package content, the UpdateIC is backed up and the IC end is updated in step S504, in order to ensure that the system can be rolled back to the previous system, backup can be carried out in the UpdateIC, S505 is the debugging package for updating the IVI, step S507 is the user to carry out reproduction operation on the vehicle until the problem can not be reproduced or the subsequent solution is solved, the debugging mode S508 can be exited, meanwhile, the debugging result is uploaded to the far end, if the problem is reproduced in S507 and the remote analysis is desired to continue to be remotely analyzed, the remote end personnel continue to execute step S2 to capture the log and analyze the self, in addition, in step S508, except the corresponding change of the interface, xml determines whether to restore the system (including restoring the data backed up in S504 and S505, deleting the downloaded debug package of S501 and the log file packaged in S403).
All functions in the implementation are independently made into a system app, wherein a LogManager, a Channel module is a lib library, an Update is an executable program with a root, a LogCache, an MtkProxy and an UpdateIC at an instrument end are executable programs, the portability is high, only one system can be debugged, other debugged systems or ECUs can be added, and the flexibility is high. The system in the implementation adopts socket communication, certainly, the communication modes between the systems are different, such as serial communication, and the system can be used by slightly modifying, thereby being double with half the effort for a platform project, greatly reducing business trip cost and time, and simultaneously improving the working efficiency.
In a specific embodiment of the invention, the service end sends an instruction to the car end, the car end analyzes data, captures a log file and uploads the log file to the service end, a debugging packet is made and sent to a car machine, the car machine downloads and updates the debugging packet, the problem is reproduced, and the result is uploaded to the service end.
In a specific embodiment of the invention, the server can remotely control the car machine end to capture the log, but the function is not limited to this, as long as the car machine does not crash, the log can be remotely captured, so that the situation that the car machine large screen touch screen has problems or the user version does not have a debugging port can be prevented.
In an embodiment of the present invention, a file-based debug package is created, and the debug is encrypted, and more configuration items can be added to the configuration file.
In a specific embodiment of the present invention, before updating the debug packet, the system needs to be backed up first to avoid the occurrence of system abnormality, and after the debugging is finished, whether to perform a system recovery operation can be selected according to the configuration data, and the cache data is cleared at the same time.
