GSM signals being present, when in the absence of GSM signals, gsm module can not be run, then coded lock is opened, it is desirable to user inputs password,
Judge that user inputs whether password is correct, if the number of input error password exceedes limited number of times, password is still incorrect, then certainly
Dynamic locking storage device, into step (5)；If inputting proper password in predetermined number of times, read successfully；When GSM letters being present
Number when, into step (4)；
(4) whether detection storage device is in the lock state determines GSM signals be present through step (3), now detects storage device
Whether it is locked, if dual-serial-port single-chip receives the short message of gsm module locking storage device, locks storage device, this is deposited
Storage equipment will be unable to read, into step (5)；If dual-serial-port single-chip did not receive the short message of locking storage device,
Storage device is read successfully；
(5) whether opening short message reminds single-chip microcomputer to detect whether that opening short message reminds, if being not turned on short message prompting, whole program
Terminate；If opening short message to remind, after each storage device reads success or failure, sent from gsm module to manipulation unit short
Letter, report the result this time read, whole EP (end of program).
