If receiving the confirmation return information, inquire about in the processing module whether be stored with historical data information；
If so, then detect whether that there are co-channel interference；
If being not present, transmission is modulated to the data message for being transmitted to the wireless radio frequency modules；
Judge whether to receive the confirmation return information of the historical data information；
If receiving the confirmation return information of the historical data information, the wireless radio frequency modules are closed, and by the place
Reason module is adjusted to resting state.
A kind of 10. communication system at internet of things data acquisition end, it is characterised in that including：
First starting module, for receive sent close to detecting module when detecting region memory of swiping the card in destination object it is pre-
If activation signal, processing module in a dormant state is adjusted to working status, and starts the RFID card reading modules of closing；
Data message receiving module, for receive the reading of RFID card reading modules radio-frequency card data message to processing module；
Second starting module, for closing the RFID card reading modules, and starts the wireless radio frequency modules of closing；
