The control module 100 may be a Micro Controller Unit (MCU) or a Central Processing Unit (CPU) module. In some embodiments, the control module 100 may also be a DSP, an FPGA, or the like, which is not limited herein.
In one embodiment, the face recognition module 200 may include a face recognition camera 210 and a laser transmitter 220.

In one embodiment, the human body sensing module may be a Passive Infrared Detector (PIR).
It should be noted that fig. 1 and the above description are only exemplary illustrations, and the embodiment of the present application does not limit any specific arrangement manner of the control module, the face recognition module, the distance measurement module, and the human body sensing module.
At present, a door lock with a face recognition function needs light supplementing when a face image is collected for face recognition, so that the clear face image is collected, but light projected by the door lock may cause harm to a human body and influence user experience. For example, for human eyes, if the laser emission power of the laser emitter of the face recognition module is too large, the human eyes may be adversely affected.
Based on the above problems, the inventor has found that after a series of researches are carried out on the existing door lock control method, no good method exists at present, and the method can be used for reducing the harm of the door lock to the human body during face recognition, so that the method is more and more important for not only facilitating unlocking of a user, but also ensuring the safety of the human body of the user. In the research process, the inventor researches the difficulty of the current door lock control, and comprehensively considers the requirements of various scenes, and provides the door lock control method, the device, the electronic equipment and the storage medium of the embodiment of the application.
The following describes a door lock control method, a door lock control device, an electronic device, and a storage medium provided in embodiments of the present application in detail.
Referring to fig. 2, an embodiment of the present application provides a door lock control method, which can be applied to a control module of the door lock. Specifically, the door lock comprises a face recognition module and a distance measurement module, and in this embodiment, the method may include the following steps:
step S110: and detecting the face distance based on the ranging module.
Wherein, the human face distance is the distance between the human face and the door lock. The distance measuring module may include, but is not limited to, an ultrasonic sensor, a laser distance meter, an infrared sensor, and the like, which are not limited herein.
The door lock can be configured with the corresponding relation between the detection value and the distance in advance, so that the face distance corresponding to the detection value can be determined according to the detection value collected by the distance measuring module, and the face distance can be detected by the distance measuring module. As one mode, a formula may be configured in advance, where an input of the formula is a detection value of the ranging module, and an output of the formula is a distance, so that a face distance corresponding to the detection value is obtained by inputting the detection value. As another mode, a mapping table between the detection value and the distance may be configured in advance, so that according to the detection value, the distance corresponding to the detection value is found from the mapping table, and the distance is determined as the face distance.
In some embodiments, the ranging module may be an infrared sensor, may be configured to emit infrared light, and may include an infrared transmitter and an infrared receiver. The distance measurement module transmits infrared light through the infrared transmitter, and the infrared receiver receives reflected light reflected back through the human face, so that the door lock can obtain the distance between the human face and the door lock according to the intensity of the received reflected light, namely the human face distance is obtained, and the human face distance is detected. It can be understood that the larger the intensity of the reflected light acquired by the ranging module, the smaller the face distance.
In some embodiments, the infrared emitter may include an infrared light emitting diode for emitting infrared light, and the infrared receiver may include a photosensitive receiver tube for receiving reflected light reflected back. In some embodiments, the infrared emitter may emit infrared light having a wavelength of 940 nm.
In some embodiments, the corresponding relationship between the intensity of the reflected light and the distance may be configured in advance, so that according to the intensity of the reflected light acquired by the ranging module, the face distance corresponding to the intensity may be determined, and thus the face distance may be detected by the ranging module. As one mode, a formula may be configured in advance, where the input of the formula is the intensity of the reflected light, and the output of the formula is the distance, so that the face distance corresponding to the intensity of the reflected light is obtained by inputting the intensity of the reflected light. As another way, a mapping table between the intensity of the reflected light and the distance may be configured in advance, so that the distance corresponding to the intensity of the reflected light may be found based on the mapping table according to the intensity of the reflected light, and the distance may be determined as the face distance.
Step S120: according to the face distance, a face recognition module is arranged to emit first light with first emission intensity.
Wherein, face identification module can launch first light, because the first light of face identification module transmission can act on the people's eye, consequently when the face distance is too little, first light probably causes the injury to the people's eye, consequently according to the face distance, set up face identification module and launch first light with first emission intensity, can adjust the first emission intensity of face identification module transmission first light when the face distance changes to reduce the injury that the lock probably caused the people's eye.
In some embodiments, the first emission intensity of the first light emitted by the face recognition module may be decreased as the distance between the face and the user decreases within the specified range. If the distance between the human face and the door lock is short, the transmitting power of the first light emitted by the human face recognition module is large, and the damage to the human body is increased, so that the first emitting intensity of the human face recognition module can be reduced according to the reduction of the distance between the human face and the door lock, the damage to the human body by the door lock can be reduced, and particularly, the damage to human eyes by the light emitted by the door lock is more remarkable, so that the damage to the human eyes can be reduced more particularly.
In some embodiments, the first emission intensity can be increased according to the increase of the face distance to improve the face recognition accuracy and the recognition sensitivity, and the first emission intensity can be decreased according to the decrease of the face distance to protect human eyes, guarantee human safety and improve the use safety of the door lock.
In other embodiments, when the distance between the face of the person exceeds a specified range, that is, when the distance between the face of the person and the door lock is far enough, the first transmission intensity may be increased along with the increase of the distance between the face of the person, so that, on the basis of ensuring the safety of the person, the first transmission intensity may be increased according to the increase of the distance between the face of the person, so as to make the face recognition more accurate.
In still other embodiments, the first emission intensity may be set to a first designated emission intensity without change when the face distance exceeds a designated range, and the first emission intensity may be set to a second designated emission intensity when the face distance does not exceed the designated range, wherein the first designated emission intensity is greater than the second designated emission intensity, so that the first emission intensity is reduced when the face distance is too small to reduce injury to the human body, and one emission intensity is kept unchanged in other cases, so as to ensure sensitivity and accuracy of face recognition of the door lock on the basis of ensuring safety of the human body.
In still other embodiments, a designated face distance may be preset, and when the face distance does not exceed the designated face distance, the first transmission intensity may be increased with an increase in the face distance and decreased with a decrease in the face distance; when the face distance exceeds the designated face distance, the first transmission intensity can be set as the designated transmission intensity without changing along with the change of the face distance, so that the first transmission intensity can be kept not to be overlarge, and the excessive resource consumption caused by the overlarge first transmission intensity can be avoided on the basis of ensuring the identifiability. The specified face distance can be preset by a program or can be customized by a user. In some examples, the specified face distance may be any value between 20cm and 1.5m, for example, 20cm, 25cm, 50cm, 1m, 1.5m, and the like, and is not limited herein.
In addition, the specified face distance can also be a distance which is safe to the human body and is obtained from the internet through the server, and the specified face distance is updated to be the distance, so that the specified face distance can be adjusted along with the development of research and detection technology and the like, the situation that the distance which is safe to the human body is actually larger than the previous distance can be avoided, for example, the previous distance which is safe to the human body is 1m, and the current distance is 1.3m, the specified face distance can be adjusted from 1m to 1.3m through the server updating, the safety of the door lock can be further improved in time, and the safety of the human body of a user can be guaranteed.
In still other embodiments, a first face distance and a second face distance may be preset, where the first face distance is smaller than the second face distance. When the face distance does not exceed the first face distance, the first emission intensity can be kept at a low value; when the face distance exceeds the first face distance but does not exceed the second face distance, the first emission intensity can be increased along with the increase of the face distance, and the first emission intensity can be reduced along with the reduction of the face distance; the first transmission intensity may be set to a high value of transmission intensity when the face distance exceeds the second face distance. Therefore, the door lock changes the first emission intensity along with the change of the face distance only when the face distance exceeds the first face distance but does not exceed the second face distance, and does not change the first emission intensity any more when the face distance is too small or too large, so that the safety of a human body can be guaranteed, and the power consumption of the door lock can be reduced.
Step S130: and acquiring a face image acquired by the face recognition module based on the first light with the first emission intensity.
In this embodiment, after the face recognition module is set to emit the first light with the first emission intensity according to the face distance, the face image acquired by the face recognition module based on the first light with the first emission intensity may be acquired. In one embodiment, the first light emitted by the face recognition module may be laser light, and the face recognition module may include a laser emitter and a face recognition camera. Specifically, the control module can control the laser transmitter to transmit laser according to the current first transmission intensity, and the face recognition camera acquires a face image, so that the face image is acquired. Because the first emission intensity is set according to the face distance, the face image acquired by the face recognition module through emitting the first light is acquired based on the set first emission intensity, so that the harm to a human body and human eyes caused by the face recognition of the door lock can be reduced, and the use safety of the door lock is improved.
Step S140: and when the face image is matched with the preset face image, executing unlocking operation.
The preset face image may be a face image of a user configured in advance. For example, user information of a door lock may be added based on an APP for managing the door lock. The user information may include a face image. Therefore, the face image of the user under the door lock can be the preset face image in the embodiment, that is, the acquired face image is matched with the face image of the user under the door lock, so that the user under the door lock can be unlocked by face recognition.
In one embodiment, the preset face image can be stored in the local part of the door lock, so that the door lock can still be unlocked by face recognition when the door lock is not networked or the network condition is poor, and the usability of the door lock is improved.
In another embodiment, the preset face image can be stored in the server, so that the storage pressure of the door lock can be reduced, the storage of the door lock is optimized, the operation efficiency of the door lock is improved, and the response speed is favorably improved.
The door lock control method, the door lock control device, the electronic equipment and the computer-readable storage medium are applied to a door lock, the door lock comprises a face recognition module and a ranging module, the face distance is detected based on the ranging module, the face distance is the distance between a face and the door lock, then the face recognition module is set to emit first light rays with first emission intensity according to the face distance, then a face image acquired by the face recognition module based on the first light rays with the first emission intensity is obtained, and finally unlocking operation is executed when the face image is matched with a preset face image. From this, this application is through detecting the distance between people's face and the lock, adjusts the emission intensity of first light to carry out face identification on this basis and unblank, can reduce the light that the lock throwed out and to the injury of human body, protect human safety, improve the safety in utilization.
Referring to fig. 3, another embodiment of the present application provides a door lock control method, which can be applied to the door lock. Specifically, the method may comprise the steps of:
step S210: and detecting the face distance based on the ranging module.
In some embodiments, the door lock may further include a human body sensing module, and the door lock may detect whether a person approaches based on the human body sensing module, and start the ranging module when the human body sensing module detects a human body, and not start the ranging module when the human body sensing module does not detect a human body, so as to reduce power consumption of the door lock.
Wherein, different human body induction modules can have different measurable distances. Human body induction modules with different measurable distances can be adopted according to specific requirements, so that the induction range of the door lock on a human body can be adjusted. From this, the lock can be based on human response module, when the distance between human and the lock is less than or equal to measurable distance, detects the human body. For example, the door lock can be configured with a human body sensing module with a measurable distance of 2 meters, and the door lock can detect a human body within a range of 2 meters based on the human body sensing module, specifically, when the distance between the human body and the door lock is less than or equal to 2 meters, the human body sensing module can detect the human body and send a signal to the control module, and the control module can control the distance measuring module to start.
In some embodiments, the measurable distance of the human body sensing module may be any value between 1m and 3m, and particularly, in one example, the measurable distance of the human body sensing module may be 1.2m, so that whether a person is in the range of 1.2m can be detected.
In one embodiment, the human body sensing module may be a PIR sensor operable to sense infrared radiation emitted by a human body and having a wavelength of about 10 microns (i.e., 10 μm).
Therefore, before the distance measurement module is started, whether a human body approaches or not can be detected based on the human body induction module, and when the human body is detected, the distance measurement module is started to detect the distance of the human face. Because human response module's consumption is less than the ranging module, and the measurable distance of human response module is generally great moreover, can be greater than the measuring distance of ranging module, consequently, before starting ranging module, can be earlier whether someone is close to through human response module detection, reduce the lock consumption.
In some embodiments, when a human body is detected, the face recognition module may be further activated to collect a face image for face recognition. In addition, when no human body is detected, the face recognition module can be kept to be closed, sleep or dormant to reduce the power consumption of the door lock, and when the human body is detected, the face recognition module is started in time, so that a user can carry out face recognition unlocking when approaching. In one example, if the measurable distance of the human body induction module is 1.2m, when a person is detected within the range of 1.2m, the human face recognition module is started to perform the human face recognition unlocking.
After the ranging module is started, the door lock can detect the distance between the human faces based on the ranging module. In one embodiment, the face distance corresponding to the infrared sensing value is determined by reading the infrared sensing value detected by the ranging module according to a pre-stored mapping relationship between the infrared sensing value and the distance. For example, the distance between the human face and the human face may be 0m when the infrared sensing value is 65536, and the distance between the human face and the human face may be 1m when the infrared sensing value is 70, where the infrared sensing value is a value obtained by analog-to-digital (a/D) conversion, the reference voltage is 3.3V, and the precision is 16.
Step S220: and judging whether the face distance is greater than the safety distance.
In this embodiment, after determining whether the face distance is greater than the safety distance, the method may include:
when the face distance is greater than the safety distance, step S230 may be executed;
when the face distance is less than or equal to the safe distance, step S240 may be performed.
Step S230: and determining a first identification emission intensity according to the face distance, and setting the first emission intensity as the first identification emission intensity.
When the face distance is greater than the safety distance, the first identification emission intensity can be determined according to the face distance, and the first emission intensity is set as the first identification emission intensity.
Step S240: the first emission intensity is set to a second identification emission intensity.
When the face distance is less than or equal to the safe distance, the control module may set the first transmission intensity to a second recognition transmission intensity.
The specific values of the first identification emission intensity and the second identification emission intensity can be set according to actual needs, can be preset by a program, and can also be user-defined, and are not limited herein.
In one embodiment, the first recognition emission intensity and the second recognition emission intensity may be fixed values, so that when the distance between the human face and the human face is greater than the safety distance, the first recognition emission intensity is maintained, and when the distance between the human face and the human face is less than or equal to the safety distance, the second recognition emission intensity lower than the first recognition emission intensity is maintained, so that when the human eye may be greatly injured, the first emission intensity is reduced, and the safety of the human eye is protected.
In another embodiment, the first recognition emission intensity may be changed along with the change of the face distance, and a mapping relationship between the distance interval and the first emission intensity may be constructed, so that the distance interval may be determined according to the face distance, and then the first emission intensity corresponding to the distance interval is determined as the first recognition emission intensity.
In some embodiments, the first emission intensity may be controlled by controlling an emission power of the face recognition module to emit a first light, which is exemplified by the first light as laser light, and the face recognition module may include a laser emitter for emitting laser light. At this time, the mapping relationship between the distance section and the first emission intensity may be constructed by constructing a mapping relationship between the distance section and the laser emission power of the laser emitter. For example, in some embodiments, the different distance intervals may respectively correspond to different laser emission powers, and the laser emission power may be a preset percentage of the rated laser emission power.
In some embodiments, optionally, a mapping relationship between the distance intervals and the laser emission power may be constructed, and different distance intervals may respectively correspond to different laser emission powers. In one example, only two distance intervals may be included, corresponding to different laser emission powers, respectively, and in this case, the first identification emission intensity and the second identification emission intensity may both be fixed values. Specifically, for example, when the distance interval is greater than the safety distance, for example, 25cm, the corresponding laser emission power may be a rated power, for example, 900 milliwatts, and may correspond to the first identification emission intensity; when the distance interval is less than or equal to 25cm, the corresponding laser emission power may be 300 milliwatts, which may correspond to the second recognition emission intensity.
In another example, the laser emission power corresponding to the distance interval greater than the safety distance may be different, that is, the first recognition emission intensity may be changed along with the change of the distance of the human face. Specifically, for example, when the distance interval is 35cm or more, the corresponding laser emission power may be 1000 mw; the corresponding laser emission power can be 600 milliwatts when the distance interval is (30cm,35 cm), the corresponding laser emission power of the target camera can be 300 milliwatts when the distance interval is (25cm, 30 cm), and the corresponding laser emission power can be 125 milliwatts when the distance interval is [0, 25 cm.
In other embodiments, the laser emission power of the laser emitter may be adjusted by adjusting the drive current of the laser emitter. When the distance between the human face and the door is smaller than or equal to the safe distance, the door lock can reduce the driving current of the laser emitter to the preset percentage of the rated driving current, so that the first emission intensity is the second identification emission intensity. The preset percentage can be set according to actual requirements, for example, 30%, 20% and the like, and the rated driving current refers to the normal driving current of the laser emitter when the distance between the human face and the laser emitter is greater than the safe distance. If the face distance is less than or equal to the safety distance, it can be shown that laser currently emitted by the laser emitter may cause damage to the eyes of the person, the emission power of the laser emitter can be reduced, and the driving current of the laser emitter is reduced to be below a current threshold, wherein the current threshold can be less than a preset percentage of a rated driving current. In some embodiments, the laser emitter can be changed into pulse emission, or the pulse emission duty ratio mode is reduced, so that the emission power is reduced. Therefore, the door lock can greatly reduce the transmitting power of the laser transmitter so as to reduce the transmitting intensity of the laser transmitter, thereby protecting the safety of human eyes to a greater extent.
Additionally, as an embodiment, the second identifying emission intensity may be zero. Specifically, in one example, the whole face recognition module may be closed, so that the laser emitter and the face recognition camera are both closed, and the first emission intensity of the face recognition module is set to be zero, thereby not only further reducing the damage of the door lock to human eyes, but also reducing the power consumption of the door lock. In another example, only the laser emitter can be turned off, and the face recognition camera is kept turned on, so that only the laser emitter needs to be turned on when the distance between the subsequent face and the door exceeds the safe distance again, and the face recognition camera does not need to be turned on again, thereby improving the response speed of face recognition, and timely obtaining a face image to perform face recognition unlocking when the distance between the face and the door lock is pulled away, namely, is larger than the safe distance.
In some embodiments, when the face distance is less than or equal to the safe distance, a prompt message may also be generated. The prompting information is used for prompting that the face distance is too close. The prompt message may be in various forms such as text, voice, and light, and is not limited herein. As an implementation manner, the prompt message may be a text prompt, the door lock further includes a display screen, and the prompt message may be displayed in the display screen in a text form to prompt that the face of the user is too close to prevent the human eyes from being injured.

From this, detect people's face distance through ranging module, when reducing the injury of first light to people's eye, can also further reduce the injury that ranging module itself probably caused to people's eye. Specifically, referring to fig. 4, the door lock control method according to another embodiment of the present application may further include steps S310 to S330, where:

In some embodiments, the first light emitted by the face recognition module is laser light, and in particular, the face recognition module may include a laser emitter, the distance measurement module may be an infrared sensor, and the infrared sensor may include an infrared emitter. Because infrared sensor self consumption is lower, and the space requirement is less moreover, so choose for use infrared sensor to detect the people's face distance, can make the lock consumption lower, the volume is less, and interior device arranges fairly simply. On the basis, the infrared sensor can detect the face distance to adjust the laser emission intensity according to the face distance, the damage to human eyes caused by face recognition can be greatly reduced on the basis of considering power consumption, size and production and manufacturing cost, the emission intensity of the ranging module is adjusted according to the face distance, the damage to the human eyes can be further reduced, and the use safety of the door lock is improved.
In some embodiments, the wavelength of the infrared light emitted by the infrared emitter is close to the wavelength of the laser light emitted by the laser emitter, for example, the wavelength of the infrared light is about 940nm, and the wavelength of some types of laser light is also about 940nm, and in this case, if the infrared emitter and the laser emitter work simultaneously, they may interfere with each other, and the door lock distance measurement and the face recognition function are affected. From this, in actual work, infrared emitter, laser emitter correspond and dispose different duty cycle to can stagger between two duty cycle, make infrared emitter and laser emitter not simultaneous transmission, in order to avoid mutual interference, guarantee that the lock can normally work.
In some embodiments, the face recognition module emits a first light based on a first duty cycle, and the distance measurement module emits a second light based on a second duty cycle, wherein effective duty cycles of the first duty cycle and the second duty cycle are staggered. The face recognition module emits first light for a period of time in a first working period, and does not emit the first light for a period of time, and the distance measurement module is the same in principle. Wherein, effective operating time is the time of module transmission light, and the effective operating time of first duty cycle is the time of face identification module transmission first light promptly, and the effective operating time of second duty cycle is the time of ranging module transmission second light. Therefore, the effective working time of the first working period and the effective working time of the second working period are staggered, so that the time for the face recognition module to emit the first light and the time for the distance measurement module to emit the second light are staggered, the face recognition module and the distance measurement module do not emit at the same time, and mutual interference is avoided.
In some examples, referring to fig. 5, fig. 5 shows a duty cycle schematic of a laser emitter and an infrared emitter. In fig. 5, (a) is a schematic diagram of a duty cycle of a corresponding laser emitter, and (b) is a schematic diagram of a duty cycle of a corresponding infrared emitter. The period a at the high level in fig. 5(a) may correspond to an operating period of the laser transmitter, and the period B at the low level may correspond to a non-operating period of the laser transmitter, that is, when the laser transmitter operates according to the duty cycle diagram shown in fig. 5(a), the laser transmitter operates in the period a, the period B does not operate, and so on, the laser transmitter may operate periodically. Correspondingly, the ir transmitter operates according to the duty cycle diagram shown in fig. 5(b), operates in the high level period, and does not operate in the low level period, which may be staggered from the duty cycle of the laser transmitter shown in fig. 5 (a). Therefore, the working time of the laser emitter and the working time of the infrared emitter are staggered, and the mutual interference between the laser emitter and the infrared emitter is greatly reduced. In some examples, the laser transmitter may be turned off during periods of inactivity or inactivity and turned back on during periods of operation.
As an embodiment, the distance measuring module may be an infrared sensor, the second light for emitting is infrared light, the second emission intensity may be an emission intensity of the infrared emitter for emitting the infrared light, at this time, when the face distance is greater than the safety distance, the first detection emission intensity is determined according to the face distance, and the second emission intensity is set as the first detection emission intensity; and when the face distance is less than or equal to the safety distance, setting the second emission intensity as a second detection emission intensity, wherein the second detection emission intensity is less than the first detection emission intensity.
In one example, the first detection emission intensity and the second detection emission intensity may both be fixed values, so that when the face distance is greater than the safety distance, the first detection emission intensity is maintained, and when the face distance is less than or equal to the safety distance, the second detection emission intensity lower than the first detection emission intensity is maintained, so that when the human eyes may be greatly injured, the second emission intensity is reduced, and the safety of the human eyes is protected.
In another example, the first detection emission intensity may be changed along with the change of the face distance, and a mapping relationship between the distance interval and the second emission intensity may be constructed, so that the distance interval may be determined according to the face distance, and then the second emission intensity corresponding to the distance interval is determined as the first detection emission intensity.
In some embodiments, the second emission intensity may be controlled by an infrared emission power of the infrared sensor to emit infrared light, and in this case, a mapping relationship between the distance interval and the second emission intensity may be constructed by constructing a mapping relationship between the distance interval and the infrared emission power of the infrared sensor. For example, in some embodiments, the different distance intervals may respectively correspond to different infrared emission powers, and the infrared emission power may be a preset percentage of a rated power of the infrared sensor.
In some embodiments, optionally, a mapping relationship between the distance intervals and the infrared emission power may be constructed, and different distance intervals may respectively correspond to different infrared emission powers. In one example, only two distance intervals may be included, each corresponding to a different infrared emission power, in which case the first detected emission intensity and the second detected emission intensity may both be fixed values. Specifically, for example, when the distance interval is greater than the safety distance, for example, 25cm, the corresponding infrared emission power may be a rated power of the infrared emitter, for example, 2 watts, and may correspond to the first detection emission intensity; when the distance interval is less than or equal to 25cm, the corresponding infrared emission power may be 0.8 watt, and may correspond to the second detected emission intensity.
In other embodiments, the second emission intensity may be controlled by the supply current, and in this case, the mapping between the distance interval and the second emission intensity may be constructed by constructing a mapping between the distance interval and the supply current of the infrared emitter. For example, in some embodiments, different distance intervals may correspond to different supply currents, respectively, and the supply current may be a specified percentage of the rated supply current.
In some embodiments, the second emission intensity of the infrared sensor emitting infrared rays may be divided into several infrared intensity modes, such as a first, a second, a third, and a fourth infrared intensity mode, and the respective corresponding supply currents may be a specified percentage of the rated supply current, such as 20%, 40%, 60%, and 100%, and the distance interval and the infrared intensity mode may correspond to a distance interval of [0, 25cm ] corresponding to the first infrared intensity mode, (25cm, 30cm ] corresponding to the second infrared intensity mode, (30cm,35cm ] corresponding to the third infrared intensity mode, and more than 35cm corresponding to the fourth infrared intensity mode, so that the distance interval in which the distance of the human face is located can be determined according to the distance of the human face, the corresponding infrared intensity mode can be determined according to the distance interval, and the first detected emission intensity is set to the infrared intensity mode, the second emission intensity may correspond to the first infrared intensity pattern, and the first detection emission intensity may correspond to the second, third, and fourth infrared intensity patterns. It is true that the specific values mentioned above may depend on the actual application.
The foregoing is merely an example, and the distance interval, the power supply current, and the like may be set according to actual needs, and are not limited herein. In some examples, the distance interval may also include only 25cm or less and 25cm or more, taking 25cm as the safety distance, the supply current at greater than 25cm may be the rated supply current, the emission intensity corresponding to the rated supply current may be the first detected emission intensity, the supply current at less than or equal to 25cm may be a specified percentage of the rated supply current, the specified percentage may be 20%, and the corresponding emission intensity may be the second detected emission intensity when the supply current is the specified percentage of the rated supply current.

When the distance D from the user to the face is smaller than or equal to 25cm, the first emission intensity is set to be the second identification emission intensity, the second emission intensity is set to be the second infrared emission intensity, the first emission intensity of the face identification module for emitting the first light is reduced, the second emission intensity of the ranging module 301 for emitting the second light is reduced, and the harm of the door lock to the human body is further reduced. The lock can be according to the face distance, adjusts the first emission intensity of face identification module transmission first light and the second emission intensity of range module transmission second light in the lump to can in time reduce first emission intensity and second emission intensity when the face distance is too near, reduce the injury that the light that the lock was thrown probably caused the human body more by a wide margin, further ensure user safety, prevent to damage people's eyes, thereby improve user experience. Even in some embodiments, the laser emitter may be turned off to further improve safety.
