Exemplarily, referring to
Exemplarily, the at least one operating device may include a fingerprint processing device 112 and a narrowband IoT (NB-IoT) device 113. The fingerprint processing device 112 includes a fingerprint processing chip 112a, a non-volatile (Flash) memory 112b, a fingerprint sensor 112c, and a sensing module 112d that can detect a user operation request. In the present embodiment, in general, the sensing module 112d is in a standby state and can acquire a user operation request at any time. For example, when a user has a fingerprint recognition request, and the user presses the fingerprint sensor 112c, the sensing module 112d is touched, therefore, the sensing module 112d can acquire the fingerprint recognition request.
Exemplarily, the sensing module 112d may generate a wake-up request based on the acquired user operation request and send it to the controller 111, so that the controller 111 enters a working mode under a trigger of the wake-up request.
In an embodiment, when the fingerprint processing device 112 is in a power-on state, the fingerprint sensor 112c may send acquired fingerprint information to the fingerprint processing chip 112a, so that the fingerprint processing chip 112a and the controller 111 can perform information interaction, to accomplish an operation corresponding to the user operation request.

It is worth noting that, in the present embodiment, the above at least one operating device may further include other peripheral devices connected to the controller 111 such as an audio device 114, a driving device 115 and a password keyboard device 116, the embodiments of the present disclosure do not limit the type and number of the operating device included in the intelligent lock system. When other functions are implemented, other operating devices may also be included, which is not limited here.
Exemplarily, the audio device 114 may be an audio device with various functions, or a buzzer or the like having a simple structure. The driving device 115 may be an engine or a motor or the like that drives unlocking. For the specific implementation of the above at least one operating device, the present embodiment does not limit thereto.

The terminal device 12 may communicate with at least one core network via a radio access network (RAN). The terminal device 12 may be a mobile terminal, such as a mobile phone (also referred as a “cellular” phone) and a computer with a mobile terminal, for example, may be a portable, compact, handheld, computer-built-in or vehicle mobile device, which exchanges voice and/or data with the radio access network. The terminal device can also be referred as subscriber unit (SU), subscriber station (SS), mobile station (MS), mobile, remote station (RS), access point (AP), remote terminal (RT), access terminal (AT), user terminal, user agent or user equipment, which is not limited here.
The technical solution of the present disclosure is described in detail below for the above application scenario.
With the rapid development of information technology, miniaturization IoT related products have also entered thousands of households. Intelligent home products have strict requirements on power consumption. For an intelligent door lock, usually two AA batteries need to ensure stable operation of the intelligent lock for 1 to 2 years. Therefore, how to design an intelligent lock system with low power consumption is very important for the competitive consumer electronics market.
At this stage, with the development of the intelligent door lock, an intelligent lock system with multiple unlocking modes becomes more and more popular. The multiple unlocking modes can include multiple modes, for example, password keyboard unlocking, fingerprint recognition unlocking, NB-IoT control unlocking, Bluetooth mode unlocking and NFC unlocking and the like, which will cause the energy consumption of the intelligent lock system with multiple unlocking modes to be large, greatly reducing the life of the intelligent lock and degrading the user experience. Therefore, in the intelligent lock system with multiple unlocking modes coexisting, reducing the standby power consumption of the entire intelligent lock system to as low as possible is a prerequisite to extend the life of the intelligent lock, and the standby power consumption itself is a key indicator to reflect the performance of the entire intelligent lock system.
In view of the above problems, the embodiments of the present disclosure provide a power supply control method of an intelligent lock and an intelligent lock system, where the power supply control method of the intelligent lock can be applied to the above intelligent lock system shown in
The technical solution of the present disclosure will be described in detail through specific embodiments below. It should be noted that the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail again in some embodiments.
Exemplarily, as shown in
Step 21: the controller acquires a wake-up request, where the wake-up request is used to indicate that the controller is in a working mode.
In the present embodiment, in general, the controller is a main control component of the intelligent lock system, and is connected to multiple operating devices of the intelligent lock system. In general, in order to save the energy consumption of the intelligent lock system, the controller can be in a sleep mode when it is in an idle state, and it enters into the working mode only when it is required to participate in performing a user operation request acquired by a peripheral operating device.
Exemplarily, in the present embodiment, when the controller is in the sleep mode, it can acquire the wake-up request sent by an operating device connected to the controller, where the wake-up request is used to indicate that the state of the controller is in the working mode, and determine the operating device sending the wake-up request, which further enables the controller to accomplish the processing corresponding to the user operation request acquired by the operating device together with the operating device.
Exemplarily, in the present embodiment, the working modes of the controller may include a sleep mode and a working mode. The sleep mode is a default working mode of the controller, and the sleep mode and the working mode can be switched with each other.
In general, the controller works in the sleep mode when it is in the idle state, and immediately enters the working mode once detecting information sent by the peripheral operating device, that is, the controller is in the working mode when it is busy, or the controller enters the working mode from the sleep mode periodically under a control of an internal timing module.
In the present embodiment, the controller may acquire the wake-up request that is generated and sent by the sensing module of the fingerprint processing device when detecting a user operation request sent by the user pressing the fingerprint sensor or the like, and may also acquire the wake-up request that is generated and transmitted to the controller through a latch by the NB-IoT device when acquiring the user operation request, the embodiments of the present disclosure do not limit the manner of acquiring the wake-up request, which may be determined according to actual situations.
Step 22: when the controller is in the working mode, the controller supplies power to the operating device corresponding to the wake-up request.
In the present embodiment, all operating devices connected to the controller can be supplied power by the controller. In general, in order to further reduce the power consumption of the entire intelligent lock system, the above at least one operating devices may all be in the power-off state (a power-down state). If a certain operating device acquires a user operation request, then the controller supplies power to it.
Exemplarily, in the present embodiment, the controller may enter the working mode from the sleep mode under a trigger of the above wake-up request, and then determine the operating device corresponding to the wake-up request according to a source of the wake-up request, and the controller supplies power to it to ensure that the operating device can work normally.
Step 23: the controller stops supplying power to the operating device when determining that the processing corresponding to the acquired user operation request has been accomplished by the operating device.
In the present embodiment, the controller in the working mode can continuously supply power to the operating device corresponding to the wake-up request until determining that the operating device has accomplished an operation corresponding to the user operation request, where the operating device can perform the acquired user operation request under the power-on state.
For example, the fingerprint processing device can accomplish operations such as fingerprint recognition, fingerprint registration, fingerprint query, and fingerprint priority setting corresponding to various user operation requests.
In an embodiment, the NB-IoT device can also receive various user operation requests such as deletion, query, registration trigger, and fingerprint priority setting sent by the user through the terminal device, and then the controller may also supply power to the fingerprint processing device when the fingerprint processing device is required to work together, to enable the fingerprint processing device to accomplish the processing corresponding to the user operation request together with the controller and the NB-IoT device.
In the present embodiment, the controller may also detect whether the operating device has accomplished the processing corresponding to the user operation request. For example, the controller detects whether a processing result fed back by the operating device has been received and, if the processing result fed back by the operating device has been received, determines that the operating device has accomplished the processing corresponding to the user operation request.
Further, in order to reduce the power consumption of the entire intelligent lock system, when the operating device has accomplished the processing corresponding to the user operation request, the controller may stop supplying power to the operating device.
In the present embodiment, the controller, as a control core of the intelligent lock system, can not only perform information interaction with peripheral operating devices, but also provide interface service, data query, status query, and notification service for the terminal devices through the NB-IoT device, therefore, it can improve the compatibility of the intelligent lock system to a certain extent.
Exemplarily, the controller of the intelligent lock system is in a low power consumption state such as the sleep mode when it is in the idle state, it automatically enters the working mode and supplies power to the operating device corresponding to the wake-up request when a peripheral operating device triggers an interrupt through the wake-up request, and stops supplying power to the operating device after the operating device has accomplished the operation corresponding to the user operation request acquired by the operating device, which greatly reduces the overall power consumption of the intelligent lock system and improves the system stability.
The power supply control method of the intelligent lock provided by the embodiment of the present disclosure, is applied to an intelligent lock system including a controller and at least one operating device. Specifically, the controller acquires a wake-up request, where the wake-up request is used to indicate that the controller is in a working mode, supplies power to an operating device corresponding to the wake-up request when the controller is in the working mode, and stops supplying power to the operating device when determining that the processing corresponding to the acquired user operation request has been accomplished by the operating device. In this technical solution, the overall power consumption of the entire intelligent lock system including the controller and at least one operating device is low, which improves the system stability and the user experience.
Exemplarily, in a possible implementation of the present disclosure, after the controller stops supplying power to the operating device, the following step may be further performed:
In the present embodiment, when the controller determines that the operating device has accomplished the operation corresponding to the user operation request and stops supplying power to the operating device, the controller itself enters the sleep mode again, which also reduces the power consumption of the controller and further reduces the overall power consumption of the intelligent lock system, thereby improving the system stability.
Exemplarily, based on the above embodiments,
Step 31: when the controller is in the sleep mode, the controller enters the working mode from the sleep mode under a control of a self-possessed timing module.
In the present embodiment, when the controller is in an idle state for a long time, in order to avoid that some pending tasks in the intelligent lock system cannot be found in time, the controller may enter the working mode from the sleep mode when the controller is in the sleep mode, to detect whether there is a pending task pending to be performed in the intelligent lock system.
Exemplarily, the controller has timing modules such as a real-time clock (RTC), and thus can be automatically woken up under a timing control of the internal RTC when no wake-up request is acquired by the controller from the outside, and enters the working mode from the sleep mode.
Step 32: when the controller is in the working mode, the controller detects whether there is a pending task in the intelligent lock system; if yes, Step 33 is performed, and if no, Step 34 is performed.
In the present embodiment, when the controller is woken up to enter the working mode, the controller can detect a state of each operating device connected thereto, and determine whether there is a pending task in the intelligent lock system. If there is a pending task, then move to Step 33 to perform a corresponding processing. If there is no pending task, then perform Step 34 to continue to enter the sleep mode.
Step 33: the controller supplies power to the operating device corresponding to the pending task, and accomplishes the processing corresponding to the pending task together with the operating device.
In the present embodiment, when the controller determines that there is a pending task in the intelligent lock system, it first determines an operating device corresponding to the pending task and supplies power to the operating device, to enable the operating device in the power-on state to accomplish an operation corresponding to the pending task together with the controller.
The specific implementation principle of this step is similar to the record in the foregoing Step 23, and details are not described herein again.
Step 34: the controller enters the sleep mode from the working mode.
In the present embodiment, when the controller determines that there is no pending task at the current moment, it enters the sleep mode from the working mode. At the same time, the controller may not supply power to the operating device connected thereto, to ensure that the power consumption of the entire intelligent lock system is lowest.
Exemplarily, the controller can control a low dropout regulator (LDO) through an input-output (JO) interface to indirectly control the power-on and power-off of peripheral operating devices, and the operating devices that do not require standby can be directly powered off, to ensure that the power consumption of the entire intelligent lock system is in a minimum state.
It can be understood that, the LDO is a linear regulator that uses a transistor or field effect transistor (FET) operating in its linear region to subtract an excess voltage from an input voltage of the controller, to generate a regulated output voltage. Finally, the regulated output voltage is supplied to the corresponding operating device, to achieve accurate power supply of the operating device and thus improve the stability of the intelligent lock system.
In the power supply control method of the intelligent lock provided by the embodiment of the present disclosure, when the controller is in the sleep mode, the controller enters the working mode from the sleep mode under the control of the self-possessed timing module, and when the controller is in the working mode, it detects whether there is a pending task in the intelligent lock system, and enters the sleep mode from the working mode when determining that there is no pending task. According to this technical solution, the controller can enter the working mode under the control of the timing module to perform detection, which can ensure that the pending task can be processed in time, thereby increasing the stability of the intelligent lock system and improving the user experience.
Exemplarily, in a possible design of the present disclosure, the above at least one operating device includes: a fingerprint processing device. Exemplarily, a schematic diagram of an interaction of the controller controlling the fingerprint processing device is firstly introduced below.
For example,
In the present embodiment, the sensing module is a module with low power consumption, for example, a ring key, which can sense a pressing operation of the user, and generate a wake-up request and send it to the fingerprint processing chip, to trigger the controller to enter the working mode.
In an embodiment, as shown in
Exemplarily, the controller can control whether the LDO supplies power to the fingerprint processing chip and the sensing module through a general purpose input/output (GPIO).
In an embodiment, as shown in
Exemplarily, the preset protocol may be a universal asynchronous receiver/transmitter (UART) protocol. In this way, before sending an instruction to the fingerprint processing chip, the controller can firstly perform encryption processing on the instruction to be sent based on the format of the UART protocol, and then send the encrypted instruction to the fingerprint processing chip.
It is worth noting that, in practical applications, the preset protocol may also be other protocols, which may be determined according to an agreed encryption manner of the controller and the fingerprint processing chip, and details are not described herein again.
Exemplarily, in the present embodiment, communication between the fingerprint processing chip and a memory can be performed based on a queued serial peripheral interface (SPI) protocol, which is a communication bus more widely used than SPI, with features of high-speed, full-duplex and synchronous, and the transmission efficiency is high.
In an embodiment, the communication between the fingerprint processing chip and the fingerprint sensor may be performed based on the SPI protocol, which is simple and easy to implement and has high universality.
The power supply control method of the intelligent lock will be described below by way of example in combination with the fingerprint processing device shown in
Step 51: the controller acquires a wake-up request sent by the fingerprint processing device through the sensing module.
Exemplarily, in the present embodiment, according to the record in
Correspondingly, referring to
Step 50a: the fingerprint processing device generates a wake-up request based on the user operation request detected by the sensing module.
In general, the sensing module does not actively send a wake-up request to the controller, but needs a trigger from the external environment. In an embodiment, when a core component of the fingerprint processing device, that is, the fingerprint processing chip, is in the power-off state, the sensing module can detect whether there is a user operation request. When a user operation request is detected, for example, a fingerprint recognition request corresponding to the user pressing the fingerprint sensor, the sensing module can generate a signal, that is, a wake-up request.
In an embodiment, the sensing module can be connected to a wake-up pin (a GPIO pin with a wake-up function) of the controller. When the wake-up pin of the controller is limited, more modules can be controlled by multiplexing the wake-up pin.
Step 50b: the fingerprint processing device sends the wake-up request to the controller through the sensing module.
In the present embodiment, when generating the wake-up request, the sensing module can send it to the controller, so that the controller enters the working mode from the sleep mode, and then supplies power to the fingerprint processing chip.
In the present embodiment, referring to
Step 52: the fingerprint processing device in a power-on state performs a processing corresponding to the user operation request, to obtain a processing result.
In the present embodiment, after entering the working mode, the controller firstly determines that an operating device corresponding to the wake-up request is the fingerprint processing device, and then supplies power to the fingerprint processing device, so that the fingerprint processing device in the power-on state performs the processing corresponding to the above-mentioned acquired user operation request to obtain the processing result.
It is worth noting that, in the present embodiment, the fingerprint processing chip is a chip with fingerprint processing capability, for example, a match on chip (MOC), which can independently complete functions such as fingerprint collection, processing and recognition, and storing user fingerprint template information.
Exemplarily, in the present embodiment, if the user operation request acquired by the fingerprint processing device is a registration request, then the fingerprint processing device performs a registration operation. Specifically, during a process of the registration operation, the fingerprint processing device may send fingerprint information collected through the fingerprint sensor each time and a result of collect succeeded/collect failed, and a failure reason to the processing device, until preset N valid fingerprint information is collected, where N is a positive integer. The fingerprint information and the result of collect succeeded/collect failed and the failure reason obtained by the fingerprint processing device during the registration operation process of collecting N valid fingerprint information are collectively referred as registration result.
In an embodiment, if the user operation request acquired by the fingerprint processing device is a recognition request or a deletion request or a query request or a fingerprint priority setting request, then the fingerprint processing device performs the above recognition request or deletion request or query request or fingerprint priority setting request, to obtain a recognition result, a deletion result or a fingerprint priority setting result, such as a recognition result including recognize succeeded/recognize failed and failure reason, a deletion result including delete succeeded/delete failed and failure reason, or a fingerprint priority setting result including fingerprint priority set succeeded/fingerprint priority set failed and failure reason.
In the present embodiment, the registration result or recognition result or deletion result or fingerprint priority setting result obtained by the fingerprint processing device through performing the corresponding operation is collectively referred as processing result.
In the present embodiment, if the fingerprint processing chip communicates with the controller through the UART protocol, the processing result may be a registration result or recognition result or deletion result or fingerprint priority setting result after encryption processing based on the format of the UART protocol.
Step 53: the fingerprint processing device sends the processing result to the controller.
Step 54: when receiving the processing result, the controller determines that the processing corresponding to the user operation request has been accomplished by the fingerprint processing device.
Exemplarily, the fingerprint processing device sends the obtained processing result to the controller, and the controller can determine whether a current task of the fingerprint processing device has been accomplished according to the received processing result, and then determine whether to continue to supply power to the fingerprint processing device.
Exemplarily, the controller performs analysis on the received processing result, and stops supplying power to the fingerprint processing device when determining that the fingerprint processing device has accomplished the processing corresponding to the user operation request, and enters the sleep mode from the working mode when determining that there are no other pending tasks.
In the present embodiment, the power on/off of the fingerprint processing chip and the sensing module of the fingerprint processing device is controlled by the controller through the LDO, with respect to the fingerprint processing device, when the controller is in the sleep mode, the fingerprint processing chip of which is in a completely power-down state, and only the sensing module is in the power-on state. Therefore, the power consumption is extremely low, the pressure of the controller is reduced, and the response speed of the controller is improved, thereby improving the user experience.
Exemplarily, in another possible design of the present disclosure, the above at least one operating device includes: an NB-IoT device. Exemplarily, a schematic diagram of working principle of the NB-IoT device triggering the controller to enter the working mode is first introduced below.
For example,
In the present embodiment, in order to save the overall power consumption of the intelligent lock system, in general, the controller and the NB-IoT device are both in the sleep mode. When the user operation request sent by the user through the terminal device is acquired, the NB-IoT device is woken up for sending a data signal to the controller.
Since the controller in the sleep mode cannot receive data normally when the NB-IoT device is woken up, at this time, in order to make the controller be woken up in time, as shown in
In the following, the power supply control method of the intelligent lock will be described by way of example in combination with the schematic diagram shown in
Step 71: the controller utilizes the latch to acquire a wake-up request sent by the NB-IoT device through the communication module.
The latch is connected to the communication module of the NB-IoT device.
In the present embodiment, referring to the record in
Exemplarily, before entering the sleep mode, the controller may firstly set the latch through an IO port. An NB chip of the NB-IoT device may send a data signal through the sending interface. The latch immediately latches the state when detecting that a level value of the data signal of a sending pin is changed, and meanwhile outputs interrupt information that is, the wake-up request.
Correspondingly, referring to
Step 70a: the NB-IoT device generates a wake-up request based on the user operation request acquired by the communication module.
In the present embodiment, in general, the communication module of the NB-IoT device does not actively send the wake-up request to the controller unless an external condition triggers it. In an embodiment, when the NB-IoT device is in a power-off state, if the communication module receives the user operation request, for example, the user operation request such as a query request or a registration request triggered by the user through the terminal device, the communication module will generate a signal, that is, the wake-up request.
Step 70b: the NB-IoT device sends the wake-up request to the controller through the communication module.
In the present embodiment, when the wake-up request is generated, the communication module may send it to the controller, so that the controller enters the working mode from the sleep mode. Exemplarily, when the controller is woken up, a wake-up source can be queried, and then a data processing logic of the corresponding device is preferentially started.
In the present embodiment, referring to
Step 72: the NB-IoT device performs a processing corresponding to the user operation request when it is in a power-on state, to obtain a processing result.
In the present embodiment, after entering the working mode, the controller firstly determines that an operating device corresponding to the wake-up request is the NB-IoT device, and then supplies power to the NB-IoT device, so that the NB-IoT device in the power-on state performs the processing corresponding to the above-mentioned acquired user operation request to obtain the processing result.
In the present embodiment, if the NB-IoT device communicates with the controller through the UART protocol, the processing result may be a result after encryption processing based on the format of the UART protocol.
Step 73: the NB-IoT device sends the obtained processing result to the controller.
Step 74: after receiving the processing result, the controller determines that the processing corresponding to the user operation request has been accomplished by the NB-IoT device.
Exemplarily, the NB-IoT device sends the obtained processing result to the controller, and the controller may determine whether a current operation of the NB-IoT device has been accomplished according to the received processing result, and then determine whether to continue to supply power to the NB-IoT device.
Exemplarily, the controller performs analysis on the received processing result, stops supplying powering to the NB-IoT device when determining that the NB-IoT device has accomplished the processing corresponding to the above-mentioned user operation request, and enters the sleep mode from the working mode when determining that there are no other pending tasks.
In the power supply control method of the intelligent lock provided by the present embodiment, if at least one operating device includes an NB-IoT device, the controller utilizes a latch to acquire a wake-up request sent by the NB-IoT device through a communication module, and then after the controller supplies power to an operating device corresponding to the wake-up request, the NB-IoT device in a power-on state performs a processing corresponding to a user operation request to obtain a processing result and sends the processing result to the controller, and the controller determines that the NB-IoT device has accomplished the processing corresponding to the user operation request after receiving the processing result. This technical solution, while ensuring the functions of the entire intelligent lock system, and can keep the entire intelligent lock system in a low power consumption state, which reduces the power consumption of the intelligent lock system, and thus leads to a good user experience.
It is worth noting that in any of the above embodiments, when the wake-up pin of the controller is limited, the present embodiment can control more modules by means of multiplexing the wake-up pin. For example, wake-up request signals of multiple modules can be latched through a latch, and then connected to an independent GPIO pin of the controller and a pin shared with other peripherals, to wake-up the controller.
Exemplarily, in a possible design of the embodiment of the present disclosure, the controller is integrated with a Bluetooth module; and the controller is in the working mode when the Bluetooth module is in a working state, and the controller is in the sleep mode when the Bluetooth module is in a non-working state.
In the present embodiment, a chip corresponding to the controller may be a chip integrated with a Bluetooth module. In order to make the intelligent lock system in a low power consumption state, when the Bluetooth module is in a working state, that is, the Bluetooth module needs to broadcast information, the controller may be in the working mode, and detect whether there is a pending task outside under the working mode. Correspondingly, when the Bluetooth module is in a non-working state, that is, during a period that the Bluetooth module is not broadcasting information, the controller is in the sleep mode to reduce the power consumption of the controller, that is, reduce the power consumption of the entire intelligent lock system.
For example, the intelligent lock system supports a Bluetooth unlocking manner, and a Bluetooth function of a terminal device can be successfully matched with a Bluetooth function of the intelligent lock system, so that the user can control opening of a corresponding door lock of the intelligent lock system through the Bluetooth function of the terminal device.
Exemplarily, in the foregoing possible design of the embodiment of the present disclosure, the controller is further integrated with a near field communication (NFC) module; the controller performs an NFC query operation through the NFC module when the Bluetooth module is in the working state.
In an embodiment, when the intelligent lock system supports a NFC function, the controller can perform an NFC query operation when the Bluetooth module is in the working state, which may ensure the power consumption of the entire intelligent lock system to be lowest.
For example, the intelligent lock system supports an NFC unlocking manner, when the user brings a device storing an access code close to the intelligent lock system, the intelligent lock system can perform recognition on the access code and then determine whether to perform an unlocking operation.
Specifically, since a transmission distance of NFC is extremely short and a speed of establishing a connection is fast, when the intelligent lock system is integrated with the NFC function, and an access card of the user or a terminal device storing the access code contacts peripherals of the intelligent lock system, the access card and the intelligent lock system can then establish a connection, to achieve an access control.
Exemplarily, in another possible design of the present embodiment, the controller may perform an NFC query operation when the NB-IoT device is in a working state, which may also ensure the power consumption of the entire intelligent lock system to be lowest.
Exemplarily, in yet another possible design of the present disclosure,
Step 81: when the operating device is performing an operation corresponding to the above-mentioned user operation request, the controller judges whether there is a need to call the audio device and/or the driving device.
In the present embodiment, when the fingerprint processing device or the NB-IoT device or other devices performs the operation corresponding to the acquired user operation request, whether there is a need to call the audio device to push the processing result or call the driving device to perform tasks such as unlocking, during the processing process or after the processing is finished, is detected.
For example, when the fingerprint processing device is performing the recognition request, whether there is a need to call the driving device to perform unlocking task, or whether there is a need to call the audio device to perform voice play task, is judged; when the fingerprint processing device is performing the query request, whether there is a need to call the audio device to perform voice play task of the query result or the like is judged; for another example, when the NB-IoT device is performing the query request sent by the user through the terminal device, whether there is a need to call the audio device to play the query result or the like is judged.
With respect to the specific manner that the operating device performs the operation corresponding to the user operation request, the present embodiment does not limit thereto, which may be determined according to actual situations.
Step 82: when determining that there is a need to call the audio device and/or driving device, the controller supplies power to the audio device and/or driving device.
Exemplarily, when the controller determines that there is a need to call the audio device and/or the driving device, the controller supplies power to the corresponding device. For example, when the fingerprint processing device needs to call the driving device to unlocking, then the driving device is supplied power, and when the fingerprint processing device needs to call the audio device to play the fingerprint recognition result and/or the query result, then the audio device is supplied power, or the like; or, when the fingerprint processing device needs to simultaneously call the driving device to unlock and needs to call the audio device to play the fingerprint recognition result and/or the query result, then the driving device and the audio device are supplied power at the same time.
Step 83: when determining that a corresponding operation has been accomplished by the audio device and/or the driving device, the controller stops supplying power to the audio device and/or the driving device.
Exemplarily, after the corresponding operation has been accomplished by the audio device and/or the driving device, the controller stops supplying power to the audio device and/or the driving device in time, which can reduce the power consumption of the intelligent lock system and improve the system stability.
Exemplarily, after the driving device performs an unlocking process, the controller stops supplying power to the driving device, to cause it to enter the power-off state; after the audio device performs a voice play process, the controller stops supplying power to the audio device, to cause it to enter the power-off state.
The audio device and the driving device in the present embodiment are powered on only when the intelligent lock system needs to call them, and then powered off after the operation has been accomplished, which realizes the low power consumption function of the intelligent lock system.
In the present embodiment, when the intelligent lock system supports a password keyboard function, the keyboard may be a keyboard with a sensing module (for example, a ring key). When a pressing operation is detected, an interrupt is triggered to wake up the controller, thereby achieving the low power consumption function.
In the power supply control method of the intelligent lock provided by the embodiment of the present disclosure, when the operating device is performing the operation corresponding to the user operation request, the controller judges whether to call the audio device and/or the driving device, and when determining to call the audio device and/or the driving device, the controller supplies power to the audio device and/or the driving device, and when determining that the corresponding operation has been accomplished by the audio device and/or the driving device, the controller stops supplying power to the audio device and/or the driving device, thereby realizing the low power consumption function, extending the life of the intelligent lock system, and improving the product competitiveness.
