Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The application provides a doorbell system and a control method thereof, which are used for solving the problem that a camera in the existing doorbell system keeps real-time monitoring and consumes a large amount of electric energy.
In a first aspect, the present application provides a doorbell system, as shown in fig. 1, comprising a camera 10, an infrared sensor 20, a movement sensor 30, and a control module 40. As is well known to those skilled in the art, doorbell systems are typically mounted on doors that can sound to alert the owner to the presence of a visitor. The camera 10 in the doorbell system has visual and monitoring functions simultaneously, and the monitoring camera 10 is installed in the doorbell 80, so that the user can know the things happening at the door when the user is not at home, and strong evidence is provided when an accident occurs.
The camera 10 is configured to acquire image information of a target area, where the image information acquired by the camera 10 may include information such as picture information and video information. By arranging the camera 10 in the doorbell system, things happening in a target area can be detected, generally speaking, the target area refers to an area near the doorbell system, such as a home door area, the range of the target area can be selected according to actual conditions, and generally speaking, the area which can be detected by the camera 10 includes the target area. The specific specification and shape of the camera 10 can be selected according to actual situations, and the application is not limited thereto, and generally, the camera 10 has basic functions such as shooting and the like, and can obtain image information of a target area.
The infrared sensor 20 is used for detecting the temperature change of the target area and sending a temperature change signal, and as is well known to those skilled in the art, the infrared sensor 20 is a sensor capable of sensing infrared rays radiated from the target area and measuring the temperature of the target area by using the physical properties of the infrared rays. In the present application, the infrared sensor 20 emits a temperature change signal when the temperature of the target area changes. When no person passes through the target area, the temperature of the target area is generally the same as the ambient temperature, for example, the ambient temperature is 20 ℃, when no person passes through the target area, the temperature of the target area is 20 ℃, and when a person passes through the target area, the temperature of the target area changes to be close to the temperature of a human body, the temperature of the human body is generally 37 ℃, and at this time, the infrared sensor 20 detects that the temperature of the target area changes and sends a temperature change signal. The specific size and shape of the infrared sensor 20 may be selected according to actual conditions, and the application is not particularly limited.
The mobile sensor 30 is configured to detect movement of a person in the target area and send a person movement signal, the mobile sensor 30 may detect a moving object in the target area, and when the mobile sensor 30 detects that the person moves in the target area, the mobile sensor may acquire person movement information in the target area and send a person movement signal, where the person movement information may include information such as a person movement track, a person movement direction, a person and door distance, and a person movement distance.
The control module 40 is configured to control the camera 10 to be turned on to obtain image information of the target area when receiving the temperature change signal and the person movement signal. The control module 40 can be connected with the infrared sensor 20, the mobile sensor 30 and the camera 10 by wire or wireless connection, generally speaking, the control module 40 is electrically connected with the infrared sensor 20, the mobile sensor 30 and the camera 10 by wire connection to avoid interference of external signals.
It should be noted that, in the present application, when the temperature of the target area does not change or/and no person moves in the target area, the camera 10 is in a sleep state, and when a person passes through the target area, the temperature of the target area changes, and the movement sensor 30 detects that the person moves in the target area, at this time, the control module 40 controls the camera 10 to start up to obtain the image information of the target area, so as to reduce the consumption of electric energy on the premise of ensuring that the abnormal condition of the target area can be detected in time.
It should be further noted that, compared with the method of controlling the opening and closing of the camera 10 by only adopting a single detection mode, the method of controlling the opening and closing of the camera 10 by adopting the infrared sensor 20 and the mobile sensor 30 in combination with detection in the present application can prevent or even avoid the false triggering of the camera 10.
If the target area is detected by the infrared sensor 20 only to control the camera 10 to be turned on or off, the ambient temperature is far lower than the temperature of the human body in winter, and if no object higher than the ambient temperature passes through the target area, for example, warm air blows through the target area, the temperature of the target area changes, and the infrared sensor 20 generates false triggering and sends a temperature change signal. When the doorbell system is placed in a complicated environment such as outdoors, for example, when it rains or the sunlight irradiates, the change range of the ambient temperature is large, and there is a change in the temperature of the target area caused by various objects passing through the target area, the infrared sensor 20 also generates false triggering and sends a temperature change signal, thereby causing the false triggering of the camera 10.
When the camera 10 is controlled to be turned on or off only by detecting the target area through the mobile sensor 30, when an object such as a vehicle passes through the target area, the temperature of the target area does not change, but the mobile sensor 30 detects that the object passes through the target area, so that the mobile sensor 30 can also send a person movement signal, and the camera 10 is triggered by mistake.
In the present application, false triggering caused by environmental temperature change and passing of an object such as a vehicle through a target area can be avoided, for example, when the target area changes due to environmental temperature, but the motion sensor 30 does not detect that the object in the current area moves, the camera 10 is not turned on, and when the motion sensor 30 detects that the object in the current area moves, but the object is an object such as a vehicle, the temperature in the target area does not change, and the camera 10 is still not turned on, by adopting the manner of combining the infrared sensor 20 and the motion sensor 30 for detection, the camera 10 is turned on only when the infrared sensor 20 detects that the temperature in the target area changes, and the motion sensor 30 detects that the object in the target area moves, so as to reduce or even eliminate false triggering of the camera 10, thereby further reducing power consumption, and the trouble to the user can be reduced, and the user experience is improved.
Specifically, in the present application, the infrared sensor 20 and the mobile sensor 30 may be set to be always on, or the mobile sensor 30 may be set to be always on, and when the mobile sensor 30 detects that the person moves and sends a person movement signal in the target area, the control module 40 controls the infrared sensor 20 to be started, so as to further reduce the consumption of electric energy.
Specifically, the control module 40 is further configured to transmit the image information of the target area to the terminal, so that the user can obtain the image information of the target area in time, and when the target area is abnormal, the user can be warned in time even if the user is not at home. The terminal can be a mobile phone, a pad, a mobile computer, a notebook, a server or a cloud terminal, and the type of the terminal is not particularly limited in the present application.
It can be understood that, in the present application, by adopting the manner of detecting by combining the infrared sensor 20 and the motion sensor 30, the false triggering of the camera 10 can be reduced or even avoided, and the useless information sent to the terminal due to the false triggering can also be reduced, so that the user experience can be improved.
With continued reference to fig. 1, in an embodiment of the present application, the control module 40 includes a determining unit 41 and a main control unit 42.
The judging unit 41 is configured to send a control signal when receiving the temperature change signal and the person movement signal; the determining Unit 41 may be electrically connected to the infrared sensor 20, the motion sensor 30 and the main control Unit 42, and configured to receive a temperature change signal sent by the infrared sensor 20 and a person movement signal sent by the motion sensor 30, and send a control signal to the main control Unit 42 when receiving the temperature change signal and the person movement signal at the same time, where the determining Unit 41 may be an MCU (Micro controller Unit).
The main control unit 42 is configured to control the camera 10 to be turned on to obtain the image information of the target area when receiving the control signal, and transmit the image information of the target area to the terminal. The main control unit 42 may be electrically connected to the camera 10 to control the opening and closing of the camera 10, when the main control unit 42 does not receive a control signal, the main control unit 42 may be in a sleep state, and when the main control unit 42 receives the control signal, the main control unit 42 rapidly starts and controls the camera 10 to start, so that the consumption of electric energy may be further reduced, and the main control unit 42 may be a main control chip.
In an embodiment of the present application, the main control unit 42 is further configured to transmit the personnel movement information of the target area to the terminal, so that when personnel movement occurs in the target area, a user can timely obtain information such as a movement track of the personnel, a movement direction of the personnel, a distance between the personnel and a door, and a movement distance of the personnel from the personnel movement information, and accurately judge whether abnormal behavior occurs in the personnel in the target area according to the information, so that a corresponding response can be timely made when abnormality occurs in the target area.
Specifically, the movement sensor 30 includes a movement detection radar for transmitting a detection signal to the target area, and detecting movement of a person in the target area and transmitting a person movement signal according to the detection signal reflected from the target area.
It can be understood that the detection signal is an electromagnetic wave, an object in the target area reflects an electromagnetic wave transmitted by the motion detection radar, when a moving object exists in the target area, the motion detection radar receives the electromagnetic wave reflected by the moving object in the target area, and determines information such as a moving speed of the object in the target area based on a frequency doppler effect generated by a relative motion between the motion detection radar and the moving object according to the reflected electromagnetic wave, and meanwhile, can determine an approximate contour of the object according to the reflected electromagnetic wave, so that whether the object moving in the target area is a person or not can be identified according to the approximate contour of the object.
It should be noted that, in the present application, the movement detection radar may detect movement of an object in the target area, and identify the object to determine the type of the object passing through the target area, and when the movement detection radar detects that there is movement of the object in the target area, and identifies that the object passing through the target area is a person, it may acquire movement information of the person in the target area, and send a movement signal of the person.
It should be noted that, as well known to those skilled in the art, when a target area is detected by using a mobile detection radar, since electromagnetic waves emitted by the mobile detection radar are transmitted to the surroundings and have a certain penetrability, the mobile detection radar may also detect the movement of indoor personnel, and when the mobile detection radar detects the movement of indoor personnel, a personnel movement signal is also sent out, so if the target area is detected only by the mobile detection radar to control the start and stop of the camera 10, and when the mobile detection radar detects the movement of indoor personnel, the camera 10 is also triggered by mistake.
In the present application, when the infrared sensor 20 is used to detect the temperature change of the target area, the thermal sensing surface 21 of the infrared sensor 20 can only receive the infrared ray radiated from the target area, and the infrared sensor 20 cannot sense the indoor temperature change, so that even if the mobile detection radar detects the movement of the indoor person, the camera 10 is not turned on, and the false triggering of the camera 10 caused by the movement of the indoor person detected by the mobile detection radar can be avoided.

With continued reference to fig. 2 to 4, specifically, the housing 60 has a containing cavity 61 inside, the mobile sensor 30 is located in the containing cavity 61 to protect the mobile sensor 30, and since the detection signal transmitted and received by the mobile sensor 30 has penetrability, the normal operation of the mobile sensor 30 is not affected by placing the mobile sensor 30 in the containing cavity 61, and meanwhile, more setting spaces can be reserved for the camera 10 and the infrared sensor 20 to facilitate the installation of the camera 10 and the infrared sensor 20.
The housing 60 includes a bottom plate 62 and a cover plate 63, and the cover plate 63 covers the bottom plate 62 to form the accommodating cavity 61 with the bottom plate 62.
