Comparator, hardware random number generator and hardware DES/3DES encryption and decryption circuit；And H26 can be by power supply power supply；It can also be by
The power supply of 13.56MHz alternating electromagnetic field, and power supply output is provided；Circuit use SWD simulation model, can by JLINK emulator into
Line program programming and debugging reduce the volume of temperature measuring label, are conducive to the miniaturization of total system.
Refering to Fig. 5, in the present invention, after temperature measuring label 1 powers on, system starts to carry out system initialization, and carries out corresponding
Configuration；Then there is temperature measurement module 11 to carry out temperature measurement, and temperature data is stored in Flash；Then default is sleep
Entering after sending mode sleep pattern and waits RF to interrupt, if do not interrupt generate if Timing measurement temperature data next time, if
There is interruption to generate then the data in Flash are loaded into RF register and are sent；The basis Flash as shown in connection with fig. 7
Operational flowchart signal, first progress Flash module initialization, is then arranged this Flash operation mode, then to Flash
Corresponding operation is carried out, end mark position is finally judged and terminates this operation；In addition, can also be locked, be unlocked to Flash
It is operated with write-protect etc.；Wherein, Flash fundamental operation mode is divided into tetra- kinds of Read, PageErase, MassErase, Program
Mode may be selected.
In conjunction with Fig. 8 and Fig. 9, in a particular embodiment, if after the chip of the first control processing module is in thermometric just
Sleep pattern can be entered, it is desirable to swipe the card immediately and read data, it is necessary to set sleep sending mode for sending mode；Equally
, the card seeking data of data terminal could be received in a sleep mode temperature measuring label 1 is arranged to sleep reception pattern, because
This needs that label is made to be in sleep reception pattern in waiting process；Wherein, sleep sending mode process are as follows: system first carries out just
Beginningization, and operating mode is set, and opens RF interruption, into sleep pattern and RF interrupt signal is waited, if receiving interrupt signal,
RF interruption is then closed, and sends the data being loaded into RF register, error flag position is finally returned to, if in being not received by
It is to be interrupted then to keep sleep state etc. for break signal；Sleep receptive pattern process specifically: system is first initialized, and
Operating mode is set, opens and detects RF interruption, if detecting interrupt signal, wake up MCU and receive data and exit to receive shape
State, returning to reception data length terminates reception pattern of sleeping, and continues waiting for interrupting if not detecting interruption.
