   1）Press two-dimentional code switch or system automatically generates Quick Response Code switching signal, system auto-initiation, inquiry variable two Tie up the lockset status information portion in the open and-shut mode generation variable two-dimension code of code lock；The cryptographic libraries in single-chip microcomputer internal memory are called, Variable function message part in gathering information production variable two-dimension code；Transfer the automatic link information generating unit of server site Point；The number data for calling lockset to open, generate unlocking identification variables code；Transfer other necessity of Quick Response Code Quick Response Code life generation Message part generates overall variable two-dimension code, and is shown on variable two-dimension code display module, while single-chip microcomputer itself basis should Variable function message part parsing local password in the Quick Response Code of generation, and by the information storage of the Quick Response Code in case calling； When described variable two-dimension code includes lockset identification division, server parses lockset identification division to ensure each two-dimensional code lock Can being serviced device differentiate, while the information of whole Quick Response Code is carried out classified and stored according to different locksets, in case inquiry is adjusted With；When described variable two-dimension code includes time showing part, when lockset status information portion shows that lockset is open mode When, its show lockset open when time point value or not now show between be worth；When lockset status information portion shows that lockset is closed During state, it shows that last lockset is opened to the time value of shut-in time section；

   2）Handheld client end is scanned, and the variable two-dimension code of scanning is given to the APP parsings in handheld client end, and APP passes through solution Analyse the automatic automatic connection server in link information part of server site；APP or server are by parsing lockset status information Part judges that lockset is opening or the state of closing；Server is by parsing the variable function information portion on variable two-dimension code Point, corresponding function is searched in the server, and calculates generation and single-chip microcomputer using information is provided in variable function message part The consistent password Y of the local password of production；When described variable two-dimension code includes time showing part, lockset identification division shows Show time value, the time value is by the timer record inside single-chip microcomputer, and the value is reset when lockset is opened and start recording, Lockset is closed and is off and is recorded as definite value, and server determines the last time by parsing the time showing part on variable two-dimension code Lockset is opened to the time value of shut-in time section, and to determine time that user uses, being determined according to the time and expenses standard should To client's fee charged；When described variable two-dimension code does not include time showing part, server is according to lockset identification part Point targetedly inquire about and transfer server internal data-base recording, to determine time that user uses, according to the time and Expenses standard determines should be to client's fee charged；

   Further, the method for server counter service charge is：Server is able to record each client corresponding account to service Device transmitting Quick Response Code, and can be judged by the lockset identification division identified on Quick Response Code client transmission Quick Response Code whether come From same lockset；For same lockset, server detects two different two dimensions with identical lockset identification division Code, and two Quick Response Codes show that lockset is closed, and the latter show the Quick Response Code of lockset closed mode with it is previous The Quick Response Code of individual display lockset closed mode has the unlocking identification variables code that difference is 1, then server judges that the lock is beaten Opened, and the client user opening given tacit consent to；If account corresponding to client is being sent with the unlocking change that difference is 1 Measure identification code and show that the period between two Quick Response Codes of lockset closed mode did not pay the service of corresponding lockset Take, then judge two should with difference be 1 unlocking identification variables code and show lockset closed mode two Quick Response Codes it Between period be period that the lockset is user service；When described variable two-dimension code includes time showing part, clothes Business device directly reads the time showing part in the Quick Response Code of last display lockset closed mode, can just parse and determine user The time used, and should be to client's fee charged according to the time and expenses standard determination；When described variable two-dimension code not During comprising time showing part, server internal database is targetedly inquired about and transferred to server according to lockset identification division Record, the time of the two clients is sent by inquiring about subscription client to server, the time difference obtained is that user makes Time, and should be to client's fee charged according to the time and expenses standard determination；

   3）Server detection sends the IP or account information of the client of Quick Response Code, whether to judge the client corresponding account There is unpaid situation, information sent if then according to the corresponding expense of status inquiry in step 2, and to client end AP P, Remind client to pay outstanding charge and the specific amount of money, enter if the expense that account corresponding to the client does not need to pay Enter next step；

   4）Server detects lockset status information portion, when lockset status information portion shows that variable two-dimension code lock is in open shape During state, APP reminds client to report or close lockset for repairment；When lockset status information portion shows that variable two-dimension code lock is closed When, and the password Y passwords parsed in above-mentioned steps 2 are sent on the APP on user's handheld client end；

   5）Reported for repairment, paid the bill according to the information of server push and with reference to actual conditions, closing lockset, or according to from service The password that device obtains passes through input through keyboard password；

   6）Single-chip microcomputer is transferred the password that local password and server obtain and is compared, if single-chip microcomputer detects Password Input 3 Still incorrect after secondary, then SCM system automatically generates Quick Response Code switching signal, regenerates new Quick Response Code, variable two-dimension code New Quick Response Code is shown on display module, system returns to above-mentioned steps 1；If the correct MCU driving unlocking circuit of password will Variable two-dimension code lock is opened；

   7）After user's use, lockset is closed, two-dimentional code switch is pressed and obtains new Quick Response Code, and by handheld client end APP the Quick Response Code of acquisition is sent to server, system returns to above-mentioned 1st step.
