Preferably, the applet comprises a WeChat applet. For example, the two-dimensional code is scanned and executed in a WeChat applet; for example, the door opening operation is performed in the WeChat applet, and so on in other embodiments, which will not be described in detail below. Therefore, the effect of controlling the lockset through the WeChat small program can be realized.
In order to reduce power consumption and save electric energy, especially prolong the service life of the lockset, preferably, the step of opening the door further comprises: enabling the door opening operation when the door opening two-dimensional code is judged to exist; for example, the door opening step includes: generating a door opening two-dimensional code according to the door opening permission; enabling the door opening operation when the door opening two-dimensional code is judged to exist; performing door opening operation within the valid period of the door opening two-dimensional code; other embodiments are analogized and will not be described in detail below. Preferably, an automatic wake-up device is adopted to judge whether the two-dimensional code for opening the door exists. Preferably, the automatic wake-up device is used for judging whether the two-dimensional code for opening the door exists within a preset range. Preferably, the predetermined range is within 30 centimeters. Preferably, the predetermined range is within 20 centimeters. Preferably, the automatic wake-up device comprises an infrared sensing device, a capacitance proximity sensing device, an ultrasonic proximity sensing device, a microwave proximity sensing device and the like.

In specific application scene, need open two-dimensional code identification module when the intelligence lock discernment two-dimensional code that opens the door with the two-dimensional code, two-dimensional code identification module power consumption is great, can't support to open for a long time when the dry battery power supply is used to the intelligence lock, and awaken up the work of two-dimensional code module with button or other modes and operate inconveniently to the user. Therefore, when the automatic wake-up device is added on the intelligent lock, and a user approaches the two-dimensional code camera on the intelligent lock by using a mobile phone or other two-dimensional code carriers, the automatic wake-up device is necessary to automatically wake up the two-dimensional code module of the intelligent lock. Especially, since the battery is used for power supply, the automatic wake-up device needs to be continuously operated, and the automatic wake-up device needs low power consumption. After the automatic wake-up device is added, the overall average power consumption of the intelligent lock is required to be at a low level, and at least, the operation of 4-section No. 5 batteries in a normal working state is required to be ensured for more than 6 months. Typically, the standby current of a smart lock that meets this requirement should be less than 120 μ Α. In a specific adopted scheme, the infrared proximity sensing chip si11143 with low power consumption is used, and the lowest power consumption of the chip can reach 9 muA when the chip works. The chip automatically transmits infrared signals at regular intervals and receives infrared signals reflected by nearby objects. And adjusting chip parameters, scanning once in 0.5 second, and generating a trigger signal by the chip when an object is 10-20cm away from the chip. Such parameter is fit for the application of intelligent lock sweep two-dimensional code. The trigger signal can be used for awakening the intelligent lock main control chip and the two-dimension code module to work and starting to scan the two-dimension code. If the two-dimensional code is not scanned within a given time, for example, 10 seconds, the intelligent lock closes the two-dimensional code module, and the main control module enters a sleep state to reduce power consumption. If the two-dimension code module is scanned, the intelligent lock judges the validity of the two-dimension code, unlocking or lock configuration and other work are executed according to the judgment result, after the work is completed, the intelligent lock closes the two-dimension code module, and the main control module enters a dormant state. Other infrared sensing chips with low power consumption can also be selected, as long as the power consumption and the scanning distance can meet the requirements. The infrared induction chip can also be automatically realized by an infrared transmitting tube, an infrared receiving tube and an ultra-low power consumption singlechip. If the intelligent lock is installed outdoors, the infrared sensing module needs to adjust parameters to avoid direct sunlight so that the module cannot work effectively. Except for the infrared sensing technology, capacitance proximity sensing, ultrasonic proximity sensing and microwave proximity sensing can be selected. Likewise, power consumption and scan distance must be sufficient for smart locks. The approach awakening method can be used for controlling the two-dimension code to identify a certain block, and can also be used for controlling other parts of the intelligent lock, such as a key module, a card swiping module and network communication modules such as WiFi, NB-IOT and the like. So that the smart lock with the corresponding modules can also reduce the power consumption of these modules.

That is, only when the two-dimensional code function is in a closed state, the total clear button can take effect; as long as the two-dimensional code function is in an opened state, the total clear button cannot take effect; therefore, the function of avoiding the two-dimension code from being closed by mistake or mistake can be realized. The specific implementation is as described in the foregoing embodiments, and is not described herein again.
In a specific application scene, a two-dimensional code unlocking function can be added on the basis of realizing a home lock function, the lock design supports versions with screens and without screens, namely, the technical scheme of the invention can be used for the lock with the screens or without the screens.

The owner opens the WeChat applet, selects to add a lock, names the lock, and inputs the administrator's password. And then generating a two-dimension code, wherein the user needs to scan the two-dimension code on the lock in one minute, the lock voice prompts the operation to be successful, and the lock registration is completed. And (4) opening the WeChat applet by the owner, and selecting the start-stop time of authorized door opening and other users to be shared. And then choose to share. The sharing authorization has two types, namely time-efficiency authorization and one-time authorization. And (3) time efficiency authorization: the starting and stopping time can be defined at will, and the door can be opened for a plurality of times within the effective time. One-time authorization: the initial time is a whole hour, for example, the effective period is one hour, and the door is out of service after being opened. Only 5 one-time authorizations are allowed for the same time period.
In the step of opening the door, other users open the WeChat applet, and if the current time is within the authorization range, the two-dimensional code can be automatically popped up. The user needs to scan the code for opening the door in one minute. The lock automatically opens the door after recognizing the correct two-dimensional code. If the user has a plurality of locks, the lock to be unlocked needs to be selected firstly; the owner can also open the WeChat applet and select the lock to be opened to open the door. Preferably, the user opens the applet and selects the target lock within a certain time to open the door. For example, pressing a virtual button may open the door. Therefore, the remote authorization can be conveniently and quickly realized, the operation of quick unlocking can be realized, and the application is very convenient.

The management step also comprises other two-dimension code management operations; for example, other two-dimensional code management operations include timing; for example, the owner selects a lock in the WeChat applet and then selects timing, generating a two-dimensional code. The lock time can be calibrated by scanning the code on the lock. For example, other two-dimensional code management operations include resetting a management password; for example, the owner selects a lock in the WeChat applet and then selects a reset, generating a two-dimensional code. The code is scanned on the lock, i.e., the administrator password is reset to 123456. Other locally added passwords or fingerprints are not changed. The management menu cancels the total clear function of the local total clear button when opening the two-dimension code and starts the two-dimension code when closing the two-dimension code.

For example, acbb029f15dda6efecd595bf71738075acbb029f15dda6efecd595bf71738075 is key2, key1 last 4B exclusive OR with lock ID.
It is to be noted that the two-dimensional code data structure is not limited to the above-mentioned two-dimensional code data structure, and other data structures may be adopted, and the above-mentioned two-dimensional code data structure should be regarded as an example and not as a specific, particular limitation. For example, with the two-dimensional code data structure, a specific operation flow is given below.
And the WeChat small program generates the two-dimensional code according to the function, and the two-dimensional code is automatically regenerated by using new current time when the two-dimensional code is displayed for more than one minute.
