Basic conception of the present invention is, alternative parent process is carried out by creating a kind of heat replacement subprocess, upgrade service is realized by parent process, and service operation is replaced subprocess by heat and realized, thus realizes serving while upgrading based on the software of monitoring vehicle not interrupting.
In order to make those skilled in the art understand technical scheme of the present invention better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Embodiment 1:
See Fig. 1, a kind of software update system based on monitoring vehicle, comprises replacement module, local upgrade module and upgrading packetization module.
Described replacement module comprises heat and replaces submodule, cold start-up submodule and monitoring submodule, wherein:
Heat is replaced submodule and is replaced parent process by creating hot subprocess of replacing, and provides service for parent process loading upgrading data and heat replacement subprocess.
The concrete engineering flow process that above-mentioned heat replaces submodule is as follows:
1, create heat and replace subprocess, the switching domain that oneself work is informed to described heat and replaces subprocess by parent process, and continues to provide and serve and wait for that the application of hot replacement subprocess is given the authority to;
2, heat replaces subprocess startup, create a new switching domain, and in the switching domain utilizing parent process to provide, data, configuration and module are loaded into carry out new module, are written into module and are in halted state, after all modules have been loaded into, notice parent process prepares to give the authority to;
3, after parent process receives the subprocess request of giving the authority to, will discharge by notification module one by one, after all module release, notice heat replaces subprocess immediately, now parent process is given the authority to, and shared resource etc. is given heat replacement subprocess, parent process is hung up subsequently, waits for the release notice of subprocess;
4, after heat replacement subprocess receives the notice of giving the authority to of parent process, selectively retain the shared resource of parent process, and allow all modules run immediately, notify that parent process can discharge subsequently;
5, after parent process release, complete the loading of upgrade data by the switching domain of oneself work, after all Data import complete, replace the working field of subprocess, configuration and module by heat and carry out new module and be loaded into, after all modules have been loaded into, notice heat is replaced subprocess and is prepared to give the authority to;
6, after heat replacement subprocess receives the parent process request of giving the authority to, will discharge by notification module one by one, after all module release, notify parent process immediately;
7, after parent process receives the notice of giving the authority to of heat replacement subprocess, all modules of parent process are allowed to run immediately, subsequently the release of notice heat replacement subprocess.
Repeat step 1 to 7, repeatedly heat can be completed and replace replacement, thus unremitting service reliable and stable when can ensure software upgrading.
Described replacement module comprises cold start-up submodule, and by creating cold start-up process, for carrying out Data import, its specific works flow process is as follows:
1, after cold start-up submodule is waken up, create a cold start-up process initialization system environments, and be loaded into for the new switching domain of cold start-up process creation one is used for module, be used for Data import;
2, once all modules have been loaded into, directly run module, carry out Data import, after all Data import complete, discharge this process.
Described monitoring submodule, the running status of submodule and cold start-up submodule is replaced for monitoring heat, and Monitoring Data is transferred to packet acquisition module, the process that in described monitoring submodule monitored over time software upgrade process, upgrade data loads, is transferred to packet acquisition module by Monitoring Data while obtaining Monitoring Data.
Described packet acquisition module comprises and wakes submodule up, analyze submodule and control submodule, by acquisition based on the software upgrade data bag of monitoring vehicle and to its decompress(ion), be used for judging to have the software of upgrade data whether in operation by waking submodule up, determine to wake corresponding module up according to judged result, then the data of decompress(ion) are transferred in the module waken up and carry out Data import, and whether utilize analysis submodule to carry out analysis software upgrading successful, and send corresponding information, control submodule is finally used to receive information, operate accordingly according to transmission information and executing.
Describedly wake submodule up, by judging whether have the software based on monitoring vehicle of upgrade data in operation, wake corresponding module up according to running status, its specific implementation is as follows:
If there is the software of upgrade data to run, then wakes heat up and replace submodule;
If there is the software of upgrade data not run, then wake cold start-up submodule up.
Described analysis submodule, by research and application data, judge whether the software upgrading based on monitoring vehicle completes, specific implementation is as follows:
Research and application data display heat is replaced submodule and cold start-up submodule and is loaded normal and all upgradings complete loading all carrying out upgrade data, then send described software upgrade success signal;
Research and application data display heat is replaced submodule and cold start-up submodule and is loaded abnormal carrying out upgrade data, or other reasons causes upgrade data can not normal load, then send described software upgrading failure information.
Described control submodule, the information that receiving and analyzing submodule sends, the information and executing according to sending operates accordingly, and its concrete operations are as follows:
If the information displaying sent based on the software upgrading failure of monitoring vehicle, then returns failure message;
