Detailed Description
In the prior art, when a user leaves from the door with the door opened, the human body induction module can be awakened, and then the intelligent door lock is awakened. After the user goes out of the door, if the user returns to confirm whether the intelligent door lock is normally closed, the human body induction module can be awakened. The intelligence lock is triggered by mistake easily, leads to the consumption of intelligence lock higher.
In the embodiment of the invention, when the existence of the moving human body is detected, the first distance between the distance measuring device and the moving human body at the first moment and the second distance between the distance measuring device and the moving human body at the second moment are obtained. And if the first distance is greater than the second distance, awakening the intelligent door lock from the dormant state. Whether the intelligent door lock is triggered or not is determined by detecting the motion trend of a moving human body, so that the power consumption of the intelligent door lock can be effectively reduced.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
The embodiment of the invention provides an intelligent door lock unlocking method, which is described in detail through specific steps with reference to fig. 1.
Step S101, the presence of a moving human body is detected.
In a specific implementation, whether a moving human body exists or not can be detected through a preset human body detection device. The human body detection device may include any one of: ultrasonic radar, passive infrared detector, microwave radar, active infrared detector.
In the embodiment of the present invention, one human body detection device may be provided, or two or more human body detection devices may be provided.
Step S102, a first distance between the distance measuring device and the moving human body at a first moment and a second distance between the distance measuring device and the moving human body at a second moment are obtained.
In the embodiment of the present invention, the human body detecting device and the distance measuring device may be the same device. That is to say, through this human detection device, both can realize the function of human response, can realize the range finding function again. For the sake of uniform description, the distance measuring devices mentioned in the following embodiments of the present invention are all devices capable of simultaneously implementing a distance measuring function and a human body sensing function.
In a specific implementation, the ranging device can operate in two different operating modes: an operation detection mode and a ranging mode. When the distance measuring device works in the action detection mode, the distance measuring device can realize the human body induction function; when the range unit works in the range mode, the range unit can realize the range function.
In an embodiment of the present invention, the ranging device may default to the motion detection mode. After the distance measuring device detects that there is a moving human body, the distance measuring device can output a trigger signal to the control unit of the intelligent door lock. And the control unit of the intelligent door lock can output a mode switching signal to the distance measuring device after receiving the trigger signal. The ranging device may switch from the motion detection mode to the ranging mode after receiving the mode switch signal.
In an embodiment of the present invention, the distance measuring device may be a probe such as a microwave radar that transmits a pulse wave to achieve the above-described functions. When the distance measuring device is in the motion detection mode, the Doppler effect can be utilized to realize the detection of the moving human body. When the distance measuring device sends the pulse wave, the intermittent working characteristics of the pulse wave can be utilized, so that the power consumption of the microwave radar is reduced.
When the distance measuring device is in the distance measuring mode, the distance measuring device utilizes the echo information of the pulse wave to determine the flight time difference or the frequency difference, and further determines the distance between the moving human body and the distance measuring device.
In the embodiment of the present invention, when the distance measuring device is in the motion detection mode, the duty cycle of the pulse wave transmitted by the distance measuring device may be time-varying.
Referring to fig. 2, a waveform diagram of a pulse wave in an embodiment of the present invention is shown. As can be seen from fig. 2, the duty cycles of the pulse waves may be different at different times.
In a specific implementation, a mapping relation between the duty cycle of the pulse wave and the time may also be configured in advance for the distance measuring device.
When the distance measuring device is in the action detection mode, the distance measuring device can also generate and transmit the pulse wave with the corresponding duty ratio according to the current moment and the current moment.
The distance measuring device can obtain the unlocking time interval of the intelligent door lock. If the current moment is within the unlocking time interval, the duty ratio of the pulse wave can be set to be within a first value range; if the current time is outside the unlocking time interval, the duty ratio of the pulse wave can be set to be within a second value range; the minimum value of the first value range is not less than the maximum value of the second value range.
That is to say, if the current time is within the unlocking time interval, it can be determined that the user may go home within the time interval, so that there is an unlocking requirement, and thus the duty ratio of the pulse wave can be increased, so that the moving human body can be detected in time. On the contrary, if the current time is outside the unlocking time interval, it can be determined that the user does not usually go home within the time range, so that the unlocking requirement does not exist usually, the duty ratio of the pulse wave can be reduced, and the power consumption of the intelligent door lock is further saved.
For example, within a one-month time period, the unlocking time interval of the intelligent door lock is 19: 00-21: 00 at night. When the current time is detected to be 12:00, the duty ratio of the pulse wave generated by the distance measuring device is 20%. When the current time is detected to be 20:00, the duty ratio of the pulse wave generated by the distance measuring device is 80%.
In the embodiment of the present invention, a first distance between the ranging device and the moving body at the first time and a second distance between the ranging device and the moving body at the second time may be obtained respectively. The first time is earlier than the second time.
That is, the distance between the moving human body and the ranging device may be acquired as the first distance at the first time T1. At a second time T2 after the first time T1, the distance between the moving human body and the ranging apparatus is acquired as a second distance.
After the distance measuring device measures the first distance, the measured first distance can be sent to the control unit of the intelligent door lock. Correspondingly, after the distance measuring device measures the second distance, the measured second distance can also be sent to the control unit of the intelligent door lock.
That is, the distance measuring device may measure the distance to the moving human body at each time, and then may transmit the obtained distance to the control unit of the smart door lock.
The distance measuring device can also send the two distances to the control unit of the intelligent door lock together after obtaining the distances between the moving human body and the distance measured at two moments.
For example, the distance measuring device may simultaneously transmit the first distance and the second distance to the control unit of the smart door lock after acquiring the first distance and the second distance.
In a specific implementation, the time difference between the first time and the second time may be predetermined. For example, the time difference between the first timing and the second timing is set to 1 s. As another example, the time difference between the first timing and the second timing is set to 2 s.
In the embodiment of the invention, the distance measuring device can be integrated in the intelligent door lock, and can also be arranged independently from the intelligent door lock. When the distance measuring device and the intelligent door lock are arranged independently, the distance measuring device can communicate with the intelligent door lock in a wired or wireless mode. For example, the ranging device communicates with the smart door lock through WIFI.
If distance measuring device and intelligent lock mutual independence set up, then distance between distance measuring device and the intelligent lock is less usually to the unable real distance's between human and the intelligent lock of characterization of distance that avoids distance measuring device to record the condition appears.
And S103, if the first distance is greater than the second distance, triggering the intelligent door lock to be awakened from the dormant state.
In specific implementation, if the first distance is greater than the second distance, the motion trend of the moving human body is represented as gradually approaching the intelligent door lock. At this point, the smart door lock may be triggered to wake up from the sleep state. After the intelligent door lock is awakened from the dormant state, the intelligent door lock can enter a working state, and can receive verification information (such as an electronic password, a fingerprint, a face image and the like) input by a user to verify whether the user is an authorized user or not, and further judge whether the intelligent door lock is unlocked or not.
On the contrary, if the first distance is smaller than the second distance, the motion trend of the moving human body is characterized to be gradually far away from the intelligent door lock. At this moment, the intelligent door lock can be continuously kept in a dormant state, and the power consumption of the intelligent door lock is further reduced.
In the embodiment of the invention, in order to more accurately determine the movement trend of the moving human body, when it is detected that the difference between the first distance and the second distance is greater than the preset distance and the difference between the first time and the second time is less than the first time, the movement trend of the moving human body can be determined to be gradually close to the intelligent door lock, so that the intelligent door lock is triggered to be awakened from the dormant state.
If the difference between the first distance and the second distance is smaller than the preset distance, even if the difference between the first time and the second time is smaller than the first duration, the moving distance of the moving human body is smaller, so that the moving human body can be determined not to have a tendency to approach the intelligent door lock, and therefore the intelligent door lock can be continuously in a dormant state. At this time, the user may simply go back to confirm whether the smart door lock is locked. Alternatively, the user may simply wait for an elevator, or simply work on clothing, etc.
Therefore, when the difference between the first distance and the second distance is detected to be larger than the preset distance and the difference between the first time and the second time is detected to be smaller than the first time, the intelligent door lock is triggered to be awakened from the dormant state. If the conditions are not met, the intelligent door lock can be continuously in the dormant state. Therefore, the intelligent door lock can be effectively prevented from being triggered by mistake, and the power consumption of the intelligent door lock is reduced.
In addition, realize human response function and range finding function through a range unit, can further reduce the cost of intelligent lock.
