This disclosure relates to the field of electronic technology, and in particular, to a method for device control, a smart lock, and a non-transitory computer-readable storage medium.
With rapid development of science and technology, smart homes are inevitable results of penetration and development of computer technology, network technology, and control technology into traditional home-appliance industries. From a level of social background, with high progress of informationization in recent years, demands for home intelligentization are greatly increased because of liberalization and high hierarchization of communication, sharply rapid increase of business volumes, and increase of requirements of humans for safety, comfort, and efficiency of working environments. In addition, in science and technology, development of computer control technology and growth of electronic information and communication technology have also contributed to birth of smart homes.
Taking smart locks as examples, smart locks often complete unlocking through fingerprint modules or digital-password input regions, but handles have relatively single functions, thereby reducing intelligence of smart locks, and thus how to improve intelligence of smart locks is an urgent problem to-be-resolved.
In a first aspect, a method for device control is provided in implementations of the disclosure. The method is applied to a smart lock, and the smart lock includes at least one sensor and a handle. The method includes the following. The at least one sensor detects a target parameter of the handle. A target operation-instruction corresponding to the target parameter is determined. The target operation-instruction is executed.
In a second aspect, a smart lock is provided in implementations of the disclosure. The smart lock includes at least one sensor configured to detect a target parameter of the handle, a processor, a memory, a communication interface, and one or more programs, where the one or more programs are stored in the memory and configured to be executed by the processor, and the programs include instructions used for executing determining a target operation-instruction corresponding to the target parameter and executing the target operation-instruction.
In a third aspect, a non-transitory computer-readable storage medium is provided in implementations of the disclosure. The computer-readable storage medium is configured to store computer programs used for electronic data interchange, where the computer programs enable a computer to execute part of or all of the operations described in the first aspect of implementations of the disclosure.

The term “implementation” referred to herein means that a particular feature, structure, or characteristic illustrated in conjunction with implementations may be contained in at least one implementation of the disclosure. The phrase appearing in various places in the specification does not necessarily refer to a same implementation, nor does it refer to an independent implementation that is mutually exclusive with other implementations or an alternative implementation. It is explicitly and implicitly understood by those skilled in the art that implementations illustrated herein may be combined with other implementations.

The following will illustrate in detail implementations of the disclosure.
Referring to
101, the at least one sensor detects a target parameter of the handle.
In implementations of the disclosure, the target parameter may refer to a related parameter detected by the smart lock when the handle is operated by a user.
In specific implementations, the target parameter may include at least one of: a handle-status parameter, the number of times of a handle being lifted, a handle-lifting duration, a handle-lifting force, a handle-operation trajectory, a handle-lifting amplitude, the number of times of a handle being pressed, a handle-pressing amplitude, a handle-holding duration, a handle-holding position, a handle-holding area, etc., which is not limited herein.
In implementations of the disclosure, the handle can rotate within a angle range, where the angle range may be or defaulted by a system. A rotating operation within specified angle ranges can be regarded as a handle-lifting operation, and a rotating operation within other specified angle ranges can be regarded as a handle-pressing operation.
For example, the target parameter may be the number of times of the handle being lifted within a duration. For another example, the target parameter may be the number of times of the handle being pressed within the duration. For yet another example, the target parameter may include both the number of times of the handle being lifted within the duration and the number of times of the handle being pressed within the duration. The duration may be or defaulted by the system. Furthermore, in specific implementations, each operation can correspond to a corresponding handle-lifting amplitude or a corresponding handle-pressing amplitude regardless of the handle that is lifted or pressed each time.
For another example, the target parameter may include a target handle-operation trajectory.
In implementations of the disclosure, the smart lock may include one or more sensors, and the sensor may include at least one of: an ultrasonic sensor, a passive infrared detection (PIR) sensor, a photoelectric sensor, a gyroscope, an acceleration sensor, a barometric sensor, a geomagnetic sensor, a touch sensor, etc., which is not limited herein.
In implementations of the disclosure, as illustrated in
Specifically, as illustrated in a dashed box in
Furthermore, in specific implementations, for detection of whether the handle is held by a human hand, as illustrated in
Furthermore, in implementations of the disclosure, as illustrated in
Optionally, the smart lock includes a dial, and the dial is used to indicate a lifting amplitude value or a pressing amplitude value of the handle. The at least one sensor detects the target parameter of the handle as follows. The at least one sensor and the dial obtain a handle-lifting action or a handle-pressing action of the handle within the duration in a process of the handle being lifted or pressed, where ach handle-lifting action corresponds to a lifting amplitude value of the handle, and each hand-pressing action corresponds to a pressing amplitude value. The handle-lifting action and the corresponding lifting amplitude value and/or the handle-pressing action and the corresponding pressing amplitude value are determined as the target parameter.
In implementations of the disclosure, the smart lock may include the dial, the dial may include multiple scales, and each scale corresponds to a handle-operation amplitude value (angle). The dial is used to indicate a lifting amplitude value or a pressing amplitude value of the handle, thereby assisting the user to view an amplitude of the handle being lifted or pressed. The duration may be or defaulted by the system, for example, the duration may be 5 s.
In specific implementations, the at least one sensor and the dial can obtain the handle-lifting action or the handle-pressing action of the handle within the duration in the process of the handle being lifted or pressed, where each handle-lifting action corresponds to the lifting amplitude value of the handle, and each hand-pressing action corresponds to the pressing amplitude value. The handle-lifting action and the corresponding lifting amplitude value and/or the handle-pressing action and the corresponding pressing amplitude value are determined as the target parameter. As such, a handle-operation parameter can be accurately collected.
102, a target operation-instruction corresponding to the target parameter is determined.
In specific implementations, different handle parameters may correspond to different operation instructions. The target operation-instruction may include at least one of: a door open instruction, a door close instruction, a doorbell control instruction, a video call instruction, a voice call instruction, an instruction for closing or opening a specified smart home device, a photographing instruction, etc., which is not limited herein. For example, the handle can be operated to open or close a light. For another example, the handle can be operated to unlock or lock. For yet another example, the handle can be operated to operate a device power-supply, etc.
Optionally, in the operation at 102, the target operation-instruction corresponding to the target parameter being determined can be implemented according to the following manner. The target operation-instruction corresponding to the target parameter is determined according to a mapping relationship between handle parameters and operation instructions.
In implementations of the disclosure, the mapping relationship between handle parameters and operation instructions can be pre-stored, and then the target operation-instruction corresponding to the target parameter is determined according to the mapping relationship.
Specifically, the mapping relationship between handle parameters and operation instructions can be illustrated in the following table.
In this way, different handle parameters may correspond to different operation parameters, thereby implementing different control functions.
Optionally, the method further includes the following.
A1, whether the target parameter meets a condition is detected.
A2, proceed to determining the target operation-instruction corresponding to the target parameter, on condition that the target parameter meets the condition.
The condition may be or defaulted by the system. For example, the condition may be lifting the handle first, or the number of times of the handle being lifted within a specified duration meeting a set number of times, which is not limited herein. The specified duration and the set number of times may be or defaulted by the system.
In specific implementations, whether the target parameter meets the condition can be detected, and proceed to determining the target operation-instruction corresponding to the target parameter on condition that the target parameter meets the condition, thereby avoiding a handle mistouch behavior, and thus improving safety.
Optionally, the at least one sensor includes a touch sensor, and the target parameter includes a target touch-parameter detected by the touch sensor. In the operation at A1, whether the target parameter meets the condition is detected as follows.
A11, the target touch-parameter and a touch-parameter are compared.
A12, it is determined that the target parameter meets the condition, on condition that the target touch-parameter matches the touch-parameter.
A13, it is determined that the target parameter fails to meet the condition, on condition that the target touch-parameter fails to match the touch-parameter.
The touch-parameter may be or defaulted by the system. The touch-parameter may include at least one of: a touch force, a touch duration, the number of times of touch/a touch frequency, a touch position, a touch area, a touch temperature, a touch humidity, etc., which is not limited herein.
In implementations of the disclosure, the touch sensor can be disposed on the handle, a touch parameter can be detected by the touch sensor when the handle is touched by the user, where the touch parameter may include at least one of: a touch force, a touch duration, the number of times of touch/a touch frequency, a touch position, a touch area, a touch temperature, a touch humidity, etc., which is not limited herein.
In specific implementations, the target touch-parameter can also be obtained first by the touch sensor, the target touch-parameter and the touch-parameter are compared, and proceed to the operation at 101 on condition that the target touch-parameter matches the touch-parameter, otherwise, subsequent operations can be skipped, thereby avoiding a touch by mistake.
Furthermore, the smart lock further includes a camera, and the method further includes the following.
A3, a target image is obtained by controlling the camera to photograph an operating object of the handle, on condition that the target parameter fails to meet the condition.
A4, the target image is stored into a storage region.
The storage region may be or defaulted by the system. The storage region may be a memory of the smart lock, a cloud, or a storage region of an edge server.
In implementations of the disclosure, the smart lock further includes the camera. In specific implementations, it can be determined that the handle is illegally operated by a stranger when the target parameter fails to meet the condition, then the target image can be obtained by controlling the camera to photograph the operation object of the handle, and the target image is stored in the storage region, so that the image of the operation object can be recorded when the handle is improperly operated, thereby improving safety.
In specific implementations, the target image is obtained by controlling the camera to photograph the operating object of the handle, so that a target environmental-parameter can be obtained, and then a target photographing-parameter corresponding to the target environmental-parameter is determined. For example, a mapping relationship between environmental parameters and photographing parameters can be pre-stored, so that the target photographing-parameter corresponding to the target environmental-parameter can be determined according to the mapping relationship, and thus the target image is obtained by focusing on the operation object and photographing the operation object of the handle according to the target photographing-parameter, thereby ensuring photographing effect and further ensuring safety. The target environmental-parameter may include at least one of: environmental light-brightness, an environmental temperature, a weather, an environmental background, etc., which is not limited herein. The target photographing-parameter may include at least one of: a sensitivity, an exposure duration, a white balance parameter, etc., which is not limited herein.
103, the target operation-instruction is executed.
In implementations of the disclosure, a corresponding target operation-instruction can be executed when a corresponding operation-instruction is generated according to a handle parameter, thereby improving safety of the smart lock. The smart lock can implement an unlock or lock function through only the handle, which can reduce cost of the smart lock and can also improve intelligence of the smart lock.
In implementations of the disclosure, a behavior of a user who wants to open or close a door can be recognized, and then the door or a window can be open or closed for the user, so that the user has a better user experience. For example, a gyroscope can be added on the smart lock, where the gyroscope can detect an open state and a closed state of the door, and the door and the window can be automatically locked when the door and the window are closed by a human.
For example, take the lock or unlock function as an example. For example, the handle is operated six times within a duration, six times of operations include two times of handle-lifting operations and four times of handle-pressing operations, where a specific operation order may be the following. A first handle operation is a handle-lifting operation, and a lifting amplitude value is a first amplitude value; a second handle operation is a handle-pressing operation, and a pressing amplitude value is a second amplitude value; a third handle operation is a handle-lifting operation, and a lifting amplitude value is a third amplitude value; a fourth handle operation is a handle-pressing operation, and a pressing amplitude value is a fourth amplitude value; a fifth handle operation is a handle-pressing operation, and a pressing amplitude value is a fifth amplitude value; and a sixth handle operation is a handle-pressing operation, and a pressing amplitude value is a sixth amplitude value. However, six times of handle operations corresponding to correct unlocking are the following. A first handle operation is a handle-lifting operation, and a lifting amplitude value is a first amplitude value; a second handle operation is a handle-pressing operation, and a pressing amplitude value is a second amplitude value; a third handle operation is a handle-lifting operation, and a lifting amplitude value is a third amplitude value; a fourth handle operation is a handle-pressing operation, and a pressing amplitude value is a fourth amplitude value; a fifth handle operation is a handle-pressing operation, and a pressing amplitude value is a fifth amplitude value; and a sixth handle operation is a handle-pressing operation, and a pressing amplitude value is a sixth amplitude value. A lock or unlock operation can be achieved through handle operations only if three conditions are satisfied, where the three conditions are that the order of the six times of handle operations and the order of the six times of handle operations are consistent, actions of the six times of handle operations and actions of the six times of handle operations are consistent, and amplitude errors between the six times of handle operations and the six times of handle operations are in a range, where the range may be or defaulted by the system, e.g., an absolute value of a difference between the first amplitude value and the first amplitude value is in the range. In specific implementations, unlocking can be achieved through handle operations when a door sometimes is difficult to be opened with a fingerprint.
Furthermore, in implementations of the disclosure, unlocking can be performed through not only conventional means (e.g., the above six times of handle operations) but also an alternative unlock manner, where the alternative unlock manner may correspond to another handle parameter. For example, a handle-parameter is detected, where the handle-parameter is a handle parameter corresponding to the alternative unlock manner, so that unlocking can be achieved, and remote alarming can also be triggered. For example, an environmental image or an environmental video can be obtained while unlocking, and then the environmental image or the environmental video is transmitted to a remote alarm system. For example, a user who sometimes is tracked or coerced can use the manner to alarm inadvertently, thereby ensuring user security and further achieving unlocking.
In specific implementations, an indication can be performed by voice or an indicator when a handle-lifting operation or a handle-pressing operation is completed each time, and a scale value can also indicate an amplitude value of each handle-lifting operation or each handle-pressing operation.
In implementations of the disclosure, considering that most of door and window sensors on a market each are composed of a “transmitter” and a “receiver”, the transmitter is generally a magnet or an infrared light, and the receiver determines whether the transmitter is nearby by receiving two types of signals transmitted by the magnet or the infrared light. It is determined that a door or a window is closed if the receiver determines that the transmitter is nearby, or it is determined that the transmitter is not nearby and the door or the window is open if the receiver determines that no signal transmitted is detected. Therefore, the door or the window sensors can detect only an open-and-closed state of the door or the window but cannot know whether the user wants to open or close the door. These sensors each are an independent device and cannot link a handle of a door or a handle of a window, while other door locks on the market capable of detecting a status of a handle are equipped with the handle customized by a manufacturer and cannot be adapted to an original door handle of a home of the user. In the disclosure, a solution for detecting opening or closing of a door or a window is provided, and the solution can be adapted to any handle. In implementations of the disclosure, the smart lock can be automatically locked or unlocked according to an action of a handle, and can also report a status of the handle or link other devices. In a specific design, an original handle can be unnecessarily changed because the sensor is placed on a smart lock. It is also possible to place an acceleration sensor, an air pressure sensor, or a geomagnetic sensor on the handle, where these sensors determine a status of the handle (lifted/pressed/static) and then transmit the status of the handle to a smart switching device through a wireless technology solution (infrared, Bluetooth, zigbee, wireless fidelity (wifi), 433, etc.).
As can be seen, the method for device control described in implementations of the disclosure is applied to the smart lock, and the smart lock includes the at least one sensor and the handle. The at least one sensor detects the target parameter of the handle. The target operation-instruction corresponding to the target parameter is determined. The target operation-instruction is executed. A related parameter of a handle operation can be detected. A handle parameter reflects an intention of the user. Furthermore, an instruction corresponding to the handle parameter can be generated, and the instruction is executed, thereby achieving the intention of the user, and thus improving intelligence of the smart lock.
