B2. current upgrading terminals is calculated the whole file verification data of whole program upgrade file by described whole file verification algorithm, and judges whether to conform to the whole file verification data of receiving; If conform to, go to B3; If do not conform to, main website does not record the whole file verification of current upgrading terminals extremely and goes to the 4th step;
B3. current upgrading terminals is carried out to reset and is restarted action, and program upgrade file is transferred to formal application area from temporary storage area, then by described whole file verification algorithm, calculate the whole file verification data of whole program upgrade file, and judge whether to conform to the whole file verification data of receiving; If conform to, main website records current upgrading terminals and upgrades successfully, and goes to the 4th step; If do not conform to, main website does not record current upgrading terminals file transfer extremely and goes to the 4th step.
The 4th step, current upgrading terminals upgrading processing finish; The whether all acquisition terminal upgrading processing of main station judging finish, and to select if not next acquisition terminal be current upgrading terminals and go to second step, if remote upgrade finishes.
Main website subsequent processing steps: each acquisition terminal program version in inquiry upgrading terminals inventory, and contrast with the version of this program upgrade file, it is that upgrade status is abnormal that version is contrasted to inconsistent acquisition terminal state recording, version is contrasted to consistent acquisition terminal communication channel and switch to information acquisition channel.
Wherein, in second step, as follows for the single frames checking algorithm detailed process of each frame blocks of files:
S1. initialization: making variable W_CRC is 16 bits, each bit value is zero; Make data pointer i=1;
S2. get 8, the left side of variable W_CRC and be saved to variable W_CRC1; Get 8, the right of variable W_CRC and be saved to variable W_CRC2;
S3. read the i byte data of present frame blocks of files, and these data and variable W_CRC2 are carried out to XOR, income value is N;
S4. the numerical value of the N order in password table and variable W_CRC1 are carried out to XOR, income value is saved to variable W_CRC; Password table by least 256 >=0x0 and≤the sexadecimal numerical value predetermined order of 0xffff forms; The initial order of password table is numbered zero;
S5. make data pointer i=i+1, judge whether present frame blocks of files reads complete, if go to S6, go to if not S2;
S6. the numerical value negate to variable W_CRC, obtains the single frames checking data of present frame blocks of files.
For ease of understanding single frames checking algorithm, lift an application example:
Certain frame blocks of files is containing two byte datas, and the 1st byte data is that 10110011, the 2 byte datas are 01011010.Move to left as logical shift left, move to right as logical shift right.
Password table is as shown in the table, contains 256 sexadecimal numerical value, and order is also with sexadecimal numeric representation:
