Description
Technical field
The present invention relates to the upgrade method of car-mounted terminal.
Background technology
Vehicle-mounted terminal equipment is directed to, is required to ensure the continual and steady of vehicle-mounted terminal equipment by system maintenance and upgrading
Operation.Car-mounted terminal upgrade method mainly has two major classes at present, and one kind is wired connection upgrading, and another kind is radio upgrade.And
Radio upgrade is mainly attached radio upgrade by GPRS public networks at this stage.
For wired connection upgrade, it is necessary to for every vehicle-mounted terminal equipment equipment be required to setting wired connection, and by
Platform is upgraded and safeguarded, not only time-consuming, trouble, but also it is (real by the equipment of wired connection to be limited to specific place
It is existing) upgraded, it is unfavorable for the upgrade maintenance of mass.For with this drawback, had at present by GPRS public networks
Network is attached the technology of radio upgrade, but is directed to this technology, and general bandwidth is limited, it is impossible to is quickly upgraded, such as
Fruit is upgraded using larger bandwidth, then can take more bandwidth resources, is spent higher cost, is unfavorable for car-mounted terminal
Upgrading；This technology is typically no simultaneously sets upgrading fault tolerant mechanism, once because channel quality goes wrong, it is most likely that
Cause equipment " change brick ", it is necessary to recovered by going out plant or other sophisticated equipments, not only influence upgrading and use, and
And cost is higher.
The content of the invention
The present invention is in order to solve to ask by the way that updating speed existing for the car-mounted terminal upgrade method of GPRS public networks is slower
Topic.
A kind of local area network wireless upgrade method of Internet of Things car-mounted terminal, comprises the following steps：
PC is connected in a manner of wifi wireless networks with car-mounted terminal, and the car-mounted terminal program software version in PC
Number it is compared with the program software version number run in car-mounted terminal, the comparison process, which passes through program and upgrades software, to be completed；
If Liang Ge version numbers comparison result is consistent, whether PC ends upgrading software can prompt version number is identical to continue to upgrade,
Selection " it is determined that " upgrading flow is then continued executing with, select " cancellation " then to stop upgrading；
If Liang Ge version numbers comparison result is inconsistent, PC ends upgrading software continues executing with upgrading flow：Upgrading software leads to
Cross http agreements and issue modification car-mounted terminal wifi transmission mode instructions (transparent mode)；
After the wifi transmission modes of car-mounted terminal are successfully modified, return to schema modification and successfully instruct (custom instruction)；PC
End upgrading software is received after this successfully instructs, by the content of the program file (xxx.bin) of upgrading with the data of 16 systems
Form is divided into bag by self-defined updating protocol and handled, and total bag number is N number of；
When car-mounted terminal receives the completion of ROMPaq file, the upgrading journey for receiving the Bale No. of data and receiving is detected
Whether the total bag number of preface part is N, if the bag number received is less than N, the Bale No. that car-mounted terminal can not receive transmitting procedure returns
PC ends upgrading software is returned, PC ends carry out benefit biography, and instruction is finished receiving until car-mounted terminal is sent；
Stored according to the size and Bale No. of ROMPaq file during car-mounted terminal received data packet, backed up simultaneously
Program before car-mounted terminal upgrading；
After the completion of car-mounted terminal receives data, size of the car-mounted terminal by data according to transmission Bale No. and ROMPaq file
It is combined and performs a ROMPaq file；
If the software version number upgraded successfully and the mark upgraded successfully can be returned to PC ends by the car-mounted terminal that runs succeeded
Upgrade software, PC ends upgrading software prompt " upgrading successfully " simultaneously terminates the upgrading to car-mounted terminal；It is vehicle-mounted if execution is unsuccessful
Terminal can automatically reset the program before re-reading the upgrading of backup, and the software version number of current car-mounted terminal and upgrading are lost
Losing mark and return to PC ends upgrading software, PC ends upgrading software can prompt " upgrading failure " and ask whether to continue to upgrade, if
Choosing " it is determined that " upgrading can be then re-executed, otherwise PC ends upgrade software by upgrading of the end to car-mounted terminal.
Preferably, the content of the program file by upgrading is assisted with the data format of 16 systems by self-defined upgrading
The process that view is divided into bag processing is as follows：
The total bag number N+ ROMPaq files of version number+ROMPaq file that first bag data carries ROMPaq file are big
The partial content data of small+ROMPaq file, the second bag to N-1 bag datas by Bale No.+ROMPaq file content data,
Last bag is made up of Bale No.+ROMPaq file content data+transmission end of identification.
Preferably, the content of the program file of upgrading is passed through into self-defined updating protocol point with the data format of 16 systems
Described self-defined updating protocol is as follows during being handled into bag：
ID is 0x01, and length corresponds to BYTE (byte),
Content：WIFI transmission modes change result：0 presentation protocol pattern, 1 represents transparent mode；
ID is 0x02, and length corresponds to WORD (word),
Content：Bale No.+version number (the only first bag)+ROMPaq file size (the first bag)+ROMPaq file content+
Receive end of identification (last bag)；
ID is 0x03, and length corresponds to BYTE (byte),
Content：Software version number+updating result；Updating result：0 represents failure, and 1 represents successfully；
ID is 0x04, and length corresponds to WORD (word),
Content：The ROMPaq file Bale No. not received is 0~N, N=<500；It is to send this needing to mend biography data
Instruction, does not otherwise send out this instruction.
Preferably, the process that the version number of car-mounted terminal program is compared the upgrading software by PC ends is such as
Under：
Upgrading software is opened after successful connection at PC ends,
ROMPaq file is wanted in the program file (xxx.bin) of passage path selection upgrading, input in software is upgraded
Version number, then click on " confirm upgrading " key；
Upgrading software issues the instruction of inquiry vehicle terminal software version number by http protocol, and car-mounted terminal is connected to instruction
Afterwards according to http protocol analysis instruction, current vehicle terminal software version number is sent to PC ends with the form of http agreements
Upgrade software；
The upgrading software at PC ends is by the current software version number of the car-mounted terminal received and the version for wanting ROMPaq file
This number is compared.
The invention has the advantages that：
Wifi technologies are very ripe at present, the present invention is carried out the local area network wireless of car-mounted terminal by wifi and upgrade
With larger bandwidth resources, not only updating speed is fast, advantage of lower cost；Simultaneously relative to existing car-mounted terminal radio upgrade
Conventional TCP/FTP agreements are upgraded, and transmission speed of the present invention is fast, upgrading efficiency high (byte per second of TCP/FTP transmission rates hundred,
Wifi upgradings can reach kilobytes/second or even can reach megabyte/second)；Compared to existing car-mounted terminal LAN without
Updating speed can be lifted 50% by line upgrade method, the present invention under conditions of identical equipment, identical ROMPaq version
More than.And the present invention devises fault tolerant mechanism, vehicle-mounted terminal equipment once upgrades failure, the version that may return to before upgrading
This, is not in the situation that car-mounted terminal can not use after upgrading is unsuccessful.As long as within the specific limits, can be at any time simultaneously
Upgraded everywhere, and updating apparatus can be moved according to actual conditions during upgrading or changes upgrading place, had
There is larger flexibility.
Brief description of the drawings
Fig. 1 is the flow chart of the present invention.
