Compared with the safety level of the electronic latch lock, the communication safety is improved. In addition, the external opening, the internal opening or the door closing can be defined from a firmware algorithm level according to scene application of hotels and the like, so that service management is facilitated. Meanwhile, the lock is compatible with the traditional touch card lock, and the quick and safe connection unlocking and the identity card unlocking of the mobile phone are supported on the basis of all functions of the traditional touch card lock.
In one example, the ios system mobile phone can be unlocked in 1s, and the android system mobile phone can be unlocked in 2 s.
In one embodiment, the door lock apparatus includes a key module, and a user can input a password through the key module to unlock the door lock apparatus. For example, 6 digits are input, and the lock is directly unlocked if the password is correct. In addition, a '11111 #' can be input to start a DFU upgrading mode of the Bluetooth, and if the Bluetooth is not upgraded in 2 minutes, the DFU is automatically quitted; inputting '555555' the door lock device can be unlocked in an activated state regardless of whether the door lock device is unlocked reversely; inputting '66666 #' to restart the door lock device; inputting 7777777 #, deleting all logs in the door lock, and resetting the storage flash.
Further, the key module further comprises a reset key, and the device key (key), all logs, the normal card reference ID and the universal card reference ID in the door lock device can be cleared by pressing the reset key for 3 seconds. Even if factory settings are restored, wherein neither the time nor the message ID is reset.
In one example, the door lock apparatus further includes a buzzer. When the unlocking is successful, triggering a buzzer to sound for a long time; when the instruction is successfully executed, triggering a buzzer to sound; when the instruction execution fails, triggering a buzzer to sound for two times; when detecting that the power supply of the power supply is insufficient or the false lock is locked, triggering a buzzer to sound three sounds; and triggering the buzzer to sound four times when detecting that the device key (key) does not exist in the door lock device.
In one embodiment, the terminal device may be an M1 card. The M1 card can be divided into M1 common card and M1 universal card. The M1 common card refers to an M1 card which can only unlock the corresponding door lock equipment; the M1 pass card refers to an M1 card that can unlock a plurality of door lock devices.
Specifically, when the M1 card is used to unlock the door lock device, the card reading process of the door lock device is as follows: when the M1 card approaches to the induction zone of the door lock equipment, the door lock equipment reads UID (user identification) information of the M1 card and judges whether a certificate is hit, and if the certificate is hit, the door is unlocked and opened directly; if not, whether the M1 card security activation code exists is judged. If the M1 card safety activation code is not detected, the unlocking operation is quitted; if the M1 card security activation code is detected, the card is verified. If the verification fails, the unlocking operation is quitted; if the verification is passed, whether the M1 card is an M1 pass card is judged, if the M1 pass card is judged, whether the card carrying the pass card reference ID is larger than or equal to the ID information stored by the door lock equipment is judged, if the card carrying the pass card reference ID, whether the card passes the verification is continuously judged, and if the card passes the verification, unlocking and opening the door is executed.
Further, if the M1 card is judged to be the M1 common card, whether the card carries the ID information stored by the common card reference ID is judged to be larger than or equal to the ID information stored by the door lock equipment, if so, whether the card passes the verification is continuously judged, if the card passes the verification, unlocking and door opening are executed, the unlocking operation of the M1 common card and the M1 common card is further realized, the communication safety is improved by one level, and the card is prevented from being cracked in batches under the condition that the central cloud server is safe. In addition, the communication is simple, and the longest instruction after encryption does not exceed 60 bytes; the requirement of enterprises (hotels, schools, offices, central machine rooms or the like) for centralized management is met.
In one embodiment, the M1 card may write the unlock information via the card issuer.
Specifically, a card sender is connected through a mobile phone, the M1 card is plugged in the card sender, and information is written into the instruction block of the M1 card through the operation of the mobile phone.
Further, when the operation of writing information to the M1 card is completed, the M1 card feeds back the information to the card issuer.
In one example, the M1 card may also issue a card write unlock message via the PC browser.
Specifically, information may be written to the M1 card by operating the PC browser. Further, it is also possible to read the M1 card-designated tile information by operating the PC browser, and delete the M1 card-designated tile information by operating the PC browser.
Further, when the operation of writing information into the M1 card is completed, the M1 card feeds back the information to the PC browser.
In one embodiment, a computer-readable storage medium is further provided, on which a computer program is stored, which when executed by a processor implements the steps of the method for communicating with an internet of things lock of any one of the above.
