Embodiment
Basic design of the present invention is; Substitute parent process through creating a kind of heat replacement subprocess; Upgrade service realizes through parent process, and service operation realizes through heat replacement subprocess, do not interrupt thereby realize serving in upgrading based on the software of monitoring vehicle.
In order to make those skilled in the art understand technical scheme of the present invention better, the present invention is done further detailed description below in conjunction with accompanying drawing and specific embodiment.
Embodiment 1:
Referring to Fig. 1, a kind of software update system based on monitoring vehicle comprises replacement module, local upgrade module and upgrading packetization module.
Said replacement module comprises heat replacement submodule, cold start-up submodule and monitoring submodule, wherein:
Heat replacement submodule is through creating heat replacement subprocess replacement parent process, and being used for parent process loading upgrading data provides service with heat replacement subprocess.
The concrete engineering process of above-mentioned heat replacement submodule is following:
1, create heat and replace subprocess, parent process notifies the switching domain of oneself work to said heat replacement subprocess, and continues to provide the application of service and wait heat replacement subprocess to give the authority to;
2, heat replacement subprocess starts; Create a new switching domain, and utilize in the switching domain that parent process provides data, configuration and module to carry out new module to be written into, to be written into module and to be in halted state; After all modules were written into completion, the notice parent process was prepared to give the authority to;
3, after parent process was received the subprocess request of giving the authority to, notification module discharged one by one, the subprocess of the hot replacement of notice immediately after all modules discharge and finish; This moment, parent process was given the authority to; And give heat replacement subprocess with shared resource etc., parent process is hung up subsequently, waits for the release notice of subprocess;
4, after heat replacement subprocess is received the notice of giving the authority to of parent process, selectively keep the shared resource of parent process, and let all modules move immediately, notify parent process to discharge subsequently;
5, after parent process discharges; Switching domain through oneself working is accomplished being written into of upgrade data, after all data load are accomplished, carries out new module through working field, configuration and the module of heat replacement subprocess and is written into; After all modules were written into completion, notice heat replacement subprocess was prepared to give the authority to;
6, after heat replacement subprocess was received the parent process request of giving the authority to, notification module discharged one by one, and all modules are notified parent process after discharging and finishing immediately;
7, after parent process is received the notice of giving the authority to of heat replacement subprocess, let all modules of parent process move immediately, notice heat replacement subprocess discharges subsequently.
Repeating step 1 to 7 can be accomplished repeatedly the heat replacement and substitute, thus reliable and stable unremitting service can guarantee software upgrading the time.
Said replacement module comprises the cold start-up submodule, through creating the cold start-up process, is used to carry out data load, and its concrete workflow is following:
1, after the cold start-up submodule is waken up, creates a cold start-up process initialization system environments, and be written into, be used for accomplishing data load for new switching domain of cold start-up process creation is used for module;
In case 2 all modules are written into completion, directly move module, carry out data load, all data load discharge this process after accomplishing.
Said monitoring submodule; Be used to monitor the running status of heat replacement submodule and cold start-up submodule; And Monitoring Data is transferred to the packet acquisition module; The process that upgrade data loads in the omnidistance monitoring of software escalation process of said monitoring submodule is transferred to the packet acquisition module with Monitoring Data when obtaining Monitoring Data.
Said packet acquisition module comprises and wakes submodule up, analyzes submodule and controlling sub; Through obtaining based on the software upgrade data bag of monitoring vehicle and to its decompress(ion); Be used for judging that with waking submodule up the software that upgrade data is arranged whether in operation, confirms to wake up corresponding module according to judged result, then the data transmission of decompress(ion) carried out data load in the module of waking up; And utilize the analysis submodule to come the analysis software upgrading whether successful; And the transmission corresponding information, use controlling sub to come reception information at last, operate accordingly according to sending information and executing.
The said submodule that wakes up, through judgement have upgrade data based on the software of monitoring vehicle whether in operation, wake corresponding module up according to running status, its concrete implementation is following:
If there is the software of upgrade data to move, then wake heat replacement submodule up;
If the not operation of software of upgrade data is arranged, then wakes the cold start-up submodule up.
Whether said analysis submodule through analyzing Monitoring Data, is judged and is accomplished based on the software upgrading of monitoring vehicle, and concrete implementation is following:
Analyze Monitoring Data and show heat replacement submodule and cold start-up submodule upgrade data loads normally and loading has all been accomplished in all upgradings carrying out, then send said software upgrade success signal;
Analyze Monitoring Data and show heat replacement submodule and cold start-up submodule in that to carry out the upgrade data loading undesired, perhaps other reasons causes the upgrade data can not normal load, then sends said software upgrading failure information.
Said controlling sub, the information that the receiving and analyzing submodule sends is operated according to the information and executing of sending accordingly, and its concrete operations are following:
If the information of sending shows the software upgrading failure based on monitoring vehicle, then return failure message;
If the information of sending shows the software upgrade success based on monitoring vehicle, then clear up upgrading data packet and decompressing files thereof, temporary file and old module associated documents etc.
The concrete workflow of above-mentioned packet acquisition module is following:
Whether S201, judgement have the software based on monitoring vehicle of upgrade data moving:
