Problems solved by technology

[0003] The current problems encountered in the development process of linux are: when the software version is integrated and submitted for integration testing, there is no log record and analysis means for problems encountered, and a machine with a debugging port is often required to reproduce and capture log logs
However, the recurrence probability of some problems is very low, resulting in problems that cannot be located in time
[0004] Obviously, the current exception capture method can no longer meet the actual project needs, and a more efficient and accurate exception location method is urgently needed to solve the problems encountered in the current actual project development

Embodiment Construction

[0045] Such as figure 1 A linux in-vehicle system abnormality diagnosis system shown, including a linux in-vehicle entertainment system, a WEB server and a PC terminal;

[0046] The linux in-vehicle entertainment system is the main control core, including remote monitoring service, core dump service, log management service, SSH service, USB protocol stack, HTTP service, TCP / IP protocol stack, USB driver, WIFI driver, 3G driver, USB Driver, WIFI module and 3G module;

[0047] The remote monitoring service is the brain of the entire system, responsible for processing the entire business logic;

[0048] The core dump service is responsible for capturing the core stack storage when the program exits abnormally, and is used to assist in locating some abnormal crash problems;

[0049] The log management service is responsible for managing system logs and performing corresponding storage and file management;

[0050] SSH service is a standard linux remote login service, which allo...

Abstract

The invention discloses an abnormality diagnosis system for a linux vehicle-mounted system in a vehicle engineering field, and the system comprises a linux vehicle-mounted entertainment system, a WEB server, and a PC end. The linux vehicle-mounted entertainment system is the master control core, and comprises modules: remote monitoring service, core dump service, log management service, SSH service, USB protocol stack, HTTP service, TCP / TP protocol stack, USB drive, WIFI drive, 3G drive, USB driver, WIFI module and 3G module. The WEB server is used for building the remote connection between a vehicle owner and a PC. The PC end provides a client, which is used for receiving an abnormality log, for a developer. The system carries out the storage of the abnormal states through employing the core dump technology of linux, achieves the remote connection and automatic uploading of the abnormality log through employing the technologies of wifi and 3G, and reports the abnormal state to the developer for analysis in the first time to maximum degree. The system and method can be used in a vehicle-mounted control system.

Description

technical field [0001] The invention relates to a vehicle control system, in particular to a fault diagnosis system. Background technique [0002] Due to its open source features and rich third-party development resources, the linux system is being favored by more and more car OEMs. However, there is no unified interface standard at present, resulting in a variety of debugging technologies for the linux system, each with its own advantages and disadvantages. Especially in terms of remote debugging and remote diagnosis, each manufacturer is currently groping for its own method. [0003] The current problems encountered in the development process of linux are: when the software version is integrated and submitted for integration testing, there is no log record and analysis means when encountering problems, and a machine with a debugging port is often required to reproduce and capture log logs. However, the recurrence probability of some problems is very low, which makes it im...
