Code.Wherein, the integrity checking code to the starting bag and each packet by carrying out checking treatment to generate.
Step S04, first sending module 14 be used for will by filling starting bag, multiple packets and end packet according to
It is secondary to send to the receiving terminal 20.
Step S05, the parsing module 21 are used to enter starting bag, multiple packets and the end packet by filling
Row is parsed and recombinated to regenerate the order bag.
It is appreciated that the parsing module 21 is respectively to starting bag, the multiple packet and the end packet
Parsed and recombinated according to bag identification code and packet number to regenerate the order bag.If it is appreciated that passing
There is no mistake during defeated, the order bag regenerated should be identical with initial command bag, if it is different, then showing in transmitting procedure
There is mistake.
Step S06, the feedback module 22 are used to carry out checking treatment to the order bag regenerated to generate instead
Present code.
Step S07, second sending module 23 are used to send the feedback code to the transmitting terminal 10.
Step S08, the judge module 15 are used to judge whether the feedback code is correct；If the feedback code is correct,
Perform step S01；If the feedback code is incorrect, step S04 is performed.
Specifically, if the feedback code is consistent with the integrity checking code, show that feedback code is correct, and then show to transmit number
Do not occur mistake during, therefore, other data to be sent can be sent；If the feedback code and the integrity checking code
It is inconsistent, then show that feedback code is incorrect, and then show occur mistake in data transmission procedure, therefore, it is necessary to the starting
Bag, the multiple packet and the end packet are sent after being refilled, untill feedback code is correct.
Data divided stator frame system 100 and method provided by the invention, applied in ZigBee data transfers, when to be transmitted
When the data volume of data is more than preset data amount, data to be transmitted is split to multiple packets and transmitted by transmitting terminal 10, receiving terminal
20 pairs of data received carry out restructuring generation data to be transmitted, and the data to be transmitted after restructuring is tested, to ensure
Data it is accurate, complete, and then realize ZigBee big data transmission, better met the demand of user.
