The detailed process of the radio upgrade method based on this wireless upgrade system is:
Step 1, set up being connected of ftp server and car-mounted terminal;
The CPU control module of step 2, car-mounted terminal is submitted username and password to ftp server, is wirelessly transmitted to ftp server by gsm module;
Step 3, ftp server judge that whether the username and password of car-mounted terminal submission is correct, if it is perform step four, if otherwise return to step 1;
Step 4, ftp server retrieving files packet;
Step 5, ftp server are downloaded the file data bag retrieving;
Step 6, ftp server judge whether file data bag is downloaded successfully, if it is performs step seven, if otherwise return to step 5;
Step 7, ftp server are upgraded the progress bar that shows upgrading number percent, judge whether file data bag is all downloaded completely, if it is performs step eight simultaneously, if otherwise return to step 4;
Step 8, according to download sequencing by all files package number, remove encrypted code and the check word of each packet, obtain total data;
Step 9, the data that step 8 is obtained connect according to connected head-to-tail pattern;
Step 10, according to the verification of full word joint cumulative sum checking mode, judge whether identical with check word, if otherwise upgrade unsuccessfully, if it is upgrade successfully.
Advantage of the present invention: the radio upgrade method based on File Transfer Protocol wireless upgrade system of the present invention, it is the problem that the wireless upgrade system for solving existing car-mounted terminal exists, the upgrade method that a kind of enterprise proposing can manage voluntarily, this upgrade method does not need platform to issue firmware, and this radio upgrade method is reliable and stable.Radio upgrade method of the present invention adopts File Transfer Protocol, File Transfer Protocol provides an interactively communication pattern for this radio upgrade, the file that allows client access to specify, and possesses discriminating control ability, also allow file to there is access right, make the method be applicable to transfer files in heterogeneous network.
The major function of this radio upgrade method has:
1, firmware data decomposed and encrypt;
2, upload firmware data to ftp server, and authority is read in setting;
3, access ftp server by GSM;
4, firmware data synthesized and decipher;
5, car-mounted terminal is taken safety upgrade after firmware.
The feature that radio upgrade method based on File Transfer Protocol wireless upgrade system of the present invention is large for wirelessly transmitting data amount, environment for use is complicated, takes full advantage of that File Transfer Protocol is efficient, secret, the advantage of intervening without platform.The hardware system of the method has that integrated level is high, memory space is large, soon and easily advantage of processing speed.Be with a wide range of applications.

Embodiment
Embodiment one: present embodiment is described below in conjunction with Fig. 1, radio upgrade method based on File Transfer Protocol wireless upgrade system described in present embodiment, wireless upgrade system based on File Transfer Protocol comprises ftp server and car-mounted terminal, and car-mounted terminal comprises gsm module, CPU control module and Serial Control module;
The detailed process of the radio upgrade method based on this wireless upgrade system is:
Step 1, set up being connected of ftp server and car-mounted terminal;
The CPU control module of step 2, car-mounted terminal is submitted username and password to ftp server, is wirelessly transmitted to ftp server by gsm module;
Step 3, ftp server judge that whether the username and password of car-mounted terminal submission is correct, if it is perform step four, if otherwise return to step 1;
Step 4, ftp server retrieving files packet;
Step 5, ftp server are downloaded the file data bag retrieving;
Step 6, ftp server judge whether file data bag is downloaded successfully, if it is performs step seven, if otherwise return to step 5;
Step 7, ftp server are upgraded the progress bar that shows upgrading number percent, judge whether file data bag is all downloaded completely, if it is performs step eight simultaneously, if otherwise return to step 4;
Step 8, according to download sequencing by all files package number, remove encrypted code and the check word of each packet, obtain total data;
Step 9, the data that step 8 is obtained connect according to connected head-to-tail pattern;
Step 10, according to the verification of full word joint cumulative sum checking mode, judge whether identical with check word, if otherwise upgrade unsuccessfully, if it is upgrade successfully.
In present embodiment, the configuration requirement of ftp server is not high, and the calculation process of File Transfer Protocol is fairly simple, does not need database yet.
Embodiment two: present embodiment is described below in conjunction with Fig. 2, present embodiment is described further embodiment one, the controller of described gsm module adopts the LEON-G100 of u-blox company, the controller of CPU control module is CPU, the DTR port ground connection of LEON-G100, after the RTS port series connection R301 resistance of LEON-G100, connect the GPRS_RTS port of CPU, after the CTS port series connection R303 resistance of LEON-G100, connect the GPRS_CTS port of CPU, R302 resistance is connected in parallel between the RTS port and CTS port of LEON-G100, after the TXD port series connection R304 resistance of LEON-G100, connect the RXD_GPRS port of CPU, the RXD port of LEON-G100 connects the TXD_GPRS port of CPU.
In present embodiment, the LEON-G100 that gsm module adopts, possesses two kinds of communication protocols of TCP and FTP.FTP communication has succinct and advantage fast, but has the unsettled shortcoming of transmission, and the bit error rate is along with weakening of GSM signal is multiplied, and the LEON-G100 performance index that the present invention adopts are better.
