Embodiment
Combine accompanying drawing and embodiment that the present invention is further specified at present.
With the GPS car-mounted terminal is the example explanation, and the technical solution adopted for the present invention to solve the technical problems whole system comprises: server 1, the Internet 2, wireless network 3, GPS car-mounted terminal 4 and operate/manage person 5.Consult shown in Figure 1ly, operate/manage person 5 uploads onto the server 1 with the AKU of handling well, and server carries out RFDC through wireless network 3 and GPS car-mounted terminal 4 to be upgraded again through the Internet 2, realizes wireless remote upgrade file system.
Consult shown in Figure 2ly, the method for realization wireless remote upgrade file of the present invention system comprises:
Step 10: make AKU; Get into
Step 20: carry is to server; Get into
Step 30: whether remote terminal regularly has the upgrading task to server lookup;

If, then do not get into step 50: do not handle; And return step 30.
The (SuSE) Linux OS that is applied in the micro embedded equipment generally is made up of boot, operating system nucleus and file system, this three part with the stores of image file in Flash.When we need revise or increase some file in the file system; Common way is the data of directly upgrading on the Flash; Through making new file system reflection, wipe corresponding Flash subregion then, and write the file system image file again and realize.Yet for coming the upgrade file system through the 3G mobile communications network, difficulty below this method exists: 1. the image file of tens000000 sizes all is being sizable test aspect delivery flow rate and the transmission rate for 3G network easily; 2. safe and reliable for what guarantee to upgrade, need earlier image file to be saved among the Flash, this Flash for low capacity can't realize, and jumbo Flash receives the restriction of cost factor.
For this reason, we expect that file system also is made up of file and catalogue one by one, can adopt file necessary in the upgrade file system, alleviate the pressure of network and disk.The coordination of each function is explained as follows with the division of labor in the system:
Step 10: specific server software becomes an AKU with all documentings that need upgrade, is made up of file number, file parameters and file data three parts.Consult shown in Figure 3, the step 10 of described making AKU specifically: step 101: storage upgrade file number; Get into step 102: storage upgrade file parameter; Get into step 103: storage upgrade file data; Get into step 104: the encoding compression AKU.Wherein, the file number has write down the number of all upgrade files, is stored in first byte of AKU; The storage format of file parameters is " [catalogue (40B)+title (40B)+length (4B)] * N ", the title of essential record upgrade file, size and the information such as position in file system; File data then is to have shielded concrete file type, and all upgrade file data of arranging according to the order of file parameters.This three part is stored in the file in order, and carry out data compression according to specific encryption algorithm.By this method, can require to obtain the corresponding upgrading bag, improve the flexibility of upgrading greatly according to different upgradings.
Step 20: carry sends to GPS car-mounted terminal through cordless communication network with AKU at the server on the internet, is stored among the Flash.In the database on the AKU of making uploaded onto the server.
Step 30: then; The GPS car-mounted terminal can whenever be logined one time equipment upgrade center at a distance from half an hour, and whether inquiry has the upgrading task, upgrading if desired; Equipment upgrade center can be passed through cordless communication network with the corresponding upgrading bag; Send to car-mounted terminal, be kept in the exclusive subregion on the Flash, and guarantee the complete, reliable of AKU transmission through specific retransmission protocol and AES.If car-mounted terminal accident power-off in data transmission procedure, equipment upgrade center can be logined the follow-up AKU that passes the back again at car-mounted terminal, thereby has saved update time, and the flow that avoids waste.If upgrading is arranged, get into step 40 and handle, if do not have, does not just handle at the terminal, and regularly inquire about the upgrading task.
Step 40: the decompress(ion) AKU, all upgrade files are copied under the catalogue corresponding in the file system, the replacement original is to reach the purpose of upgrade file system.Consult shown in Figure 4ly, described step 40 further is: step 401: the decoding AKU; Get into step 402: read in the internal memory of terminal; Get into
Step 403: judge whether upgrade applications; If then get into step 404: application programs is carried out back-up processing; And entering step 405; If, then do not get into step 405: under assigned catalogue, write the upgrade file data.Because the Flash space is limited,, at first AKU is carried out decode operation for the big file of can upgrading; And according to information such as file number, file parameters; Read each upgrade file data in internal memory, find the original under the assigned catalogue in the file system then, write data.If upgrading is application program, cause the equipment paralysis in order to prevent car-mounted terminal accident power-off in the reading and writing data process, application programs has been done back-up processing.When car-mounted terminal re-powers, detect can't operate as normal the time, can start stand-by program, the AKU in the exclusive subregion of retrieval upgrading automatically then, and carry out updating operation once more, thus the equipment of assurance is safe and reliable.
Although specifically show and introduced the present invention in conjunction with preferred embodiment; But the those skilled in the art should be understood that; In the spirit and scope of the present invention that do not break away from appended claims and limited; Can make various variations to the present invention in form with on the details, be protection scope of the present invention.
