[0043] See also Figure 1 , which is a framework diagram of the Internet of Things system for optional application scenarios of the smart home control method provided in the embodiment of the present application. Among them, the Internet of Things system is composed of a composite sensor 10, a gateway device 53, a cloud 52, a terminal device 51, etc. The terminal device 51 can be any intelligent device with communication and storage functions, such as: a smart phone, a desktop computer, a laptop computer, a tablet computer or other intelligent communication device with a network connection function. The cloud 52 can be a network access server, a database server, a cloud server, etc. Optionally, the gateway device 53 can be built based on the ZigBee protocol, and the smart home device 55 can be controlled by the composite sensor 10 or the terminal device 51, and can be pre-added to the gateway device 53. For example, the smart home device 55 can be a device in the kit to which the gateway device belongs when the gateway device 53 leaves the factory; it can also be a device subsequently connected to the gateway device 53 through user operation.

[0044] Optionally, a client that can manage the smart home device 55 is installed in the terminal device 51. The client can be an application client (such as a mobile phone APP) or a web client, which is not limited here.

[0045] Optionally, the composite sensor 10 may establish a network connection with the gateway device 53 based on the ZigBee protocol, thereby joining the ZigBee network.

[0046] The composite sensor 10, the terminal device 51 and the smart home device 55 can all be connected to the Ethernet through the gateway device 53, and the gateway device 53 can be connected to the server through a wired or wireless communication connection. For example, the gateway device 53 and the terminal device 51 can store the acquired information in the cloud 52. Optionally, the terminal device 51 can also establish a network connection with the cloud 52 through 2G / 3G / 4G / 5G, WiFi, etc., so as to obtain data sent by the cloud 52.

[0047] Optionally, the terminal device 51, the gateway device 53 and the composite sensor 10 may be in the same local area network, or in the same wide area network as the cloud 52. When the terminal device 51 and the gateway device 53 are in the same local area network, the terminal device 51 may interact with the gateway device 53 and the composite sensor 10 connected to the gateway device 53 through the local area network path; or may interact with the gateway device 53 and the composite sensor 10 connected to the gateway device 53 through the wide area network path. When the terminal device 51 and the gateway device 53 are not in the same local area network, the terminal device 51 may interact with the gateway device 53 and the composite sensor 10 connected to the gateway device 53 through the wide area network path. The Internet of Things system can further realize the control of turning on or off the smart home device 55 within the local area network or connected thereto through the composite sensor 10. The smart home device 55 may include, but is not limited to, smart home products such as smart lamps, automatic curtains, and air conditioners.

[0048] Automation refers to the linkage application built between the gateway device or the sub-devices connected to the gateway device; Automation includes trigger conditions and execution actions. The devices that realize automated scene control include trigger devices and controlled devices (or execution devices). The two are connected through the gateway. When the trigger device meets the trigger condition, the gateway controls the controlled device to perform the corresponding execution action. Among them, the trigger device can be various sensors such as pressure sensors, temperature sensors, humidity sensors, door and window sensors or smoke sensors. The controlled device can be various switches, sockets, lights, infrared transmitters or camera devices. The trigger device and the controlled device can be the same device.

[0049] Assume that a user sets an automated scene control to automatically turn on the lights when the doors and windows are opened. The condition of this scene is that the doors and windows are opened, and the execution action is that the smart switch controls the light bulb to turn on the lights. Based on this application scenario, the door and window sensors can be set as trigger devices, and the smart switches connected to the lamps can be set as controlled devices. The specific execution principle is: if the automation is performed locally on the gateway through the LAN path, the door and window sensors sense that the doors and windows are opened, and report this event to the gateway. After the gateway receives the event that the doors and windows are opened, it finds the corresponding device for executing the action according to the stored automation configuration information, which is the smart switch in this embodiment, and notifies the smart switch to turn on the lights, thereby realizing an automated linkage when the doors and windows are opened and automatically turn on the lights. If the automation is performed in the cloud through the WAN path, the door and window sensors sense that the doors and windows are opened, and report this event to the gateway. After the gateway receives the event that the doors and windows are opened, it reports this event to the cloud. The cloud finds the corresponding device for executing the action according to the stored scene configuration information, which is the smart switch in this embodiment, and notifies the smart switch to turn on the lights through the gateway. When the light is turned on, a message of successful turning on of the light is fed back to the gateway. After the gateway learns that the light is turned on successfully, it reports the current time and the message of success or failure to the cloud, which is responsible for storing it.

[0050] See also Figure 2 , a target object motion detection method provided by an embodiment of the present application, can be applied to Figure 1 The target object motion detection method includes but is not limited to S101 and S103, which are described in detail as follows:

[0051] S101, determining whether a first detection signal of a target object moving within a first detection range and a second detection signal of the target object moving within a second detection range are collected; wherein the first detection range at least partially overlaps with the second detection range to form an overlapping area and a non-overlapping area.

[0052] The composite sensor has a first detection range and a second detection range, the first detection range and the second detection range only partially overlap, and multiple different areas are distinguished by partial overlap and partial non-overlap between the first detection range and the second detection range. The target object may refer to an object moving in a smart home device control scene. In this embodiment, the smart home control method detects the position and state of a person in different areas of the home by a composite sensor, and controls the smart home devices in the corresponding area to turn on according to the detection results. In an optional embodiment, the first detection signal of the target object moving in the first detection range refers to the detection signal of the composite sensor detecting the movement of a person in the first detection range, and the second detection signal of the target object moving in the second detection range refers to the detection signal of the composite sensor detecting the movement of a person in the second detection range.

[0053] S103: Determine the movement state of the target object in the overlapping area and the non-overlapping area according to the presence or absence and generation time of the first detection signal and the second detection signal.

[0054] The composite sensor determines the movement state of the target object in the overlapping area and the non-overlapping area according to the presence or absence of the first detection signal and the second detection signal and the generation time. Optionally, the combination of the movement state of the target object determined according to the presence or absence of the first detection signal and the second detection signal and the generation time includes: only the first detection signal is detected, and it is determined that the target object enters the non-overlapping area where the first detection range exceeds the second detection range; only the second detection signal is detected, and it is determined that the target object enters the non-overlapping area where the second detection range exceeds the first detection range; the first detection signal and the second detection signal are detected at the same time, and the time when the first detection signal is generated is earlier than the time when the second detection signal is generated, it can be determined that the target object first enters the non-overlapping area where the first detection range exceeds the second detection range, and then enters the overlapping area; the first detection signal and the second detection signal are detected at the same time, and the time when the first detection signal is generated is later than the time when the second detection signal is generated, it can be determined that the target object first enters the non-overlapping area where the second detection range exceeds the first detection range, and then enters the overlapping area.

[0055] In the above embodiment, the composite sensor is used to determine whether a first detection signal indicating the movement of the target object within the first detection range and a second detection signal indicating the movement of the target object within the second detection range are collected. The movement state of the target object in the overlapping area and the non-overlapping area is determined based on the presence or absence and generation time of the first detection signal and the second detection signal. The overlapping area and the non-overlapping area are formed by the first detection range and the second detection range, so that the movement state of the target object in multiple different areas can be accurately distinguished, thereby reducing the occurrence of false alarms. Secondly, the positioning of target objects in multiple areas can be achieved through a single composite sensor, so that multi-area differentiation control can be achieved based on a single composite sensor, which can reduce hardware costs and the design cost of the composite sensor installation position. Multi-area differentiation detection can be achieved based on the detection signal of a single composite sensor, which is convenient for simplifying the control logic according to the detection results.

[0056] In some embodiments, the first detection range is an infrared band signal detection range, the second detection range is a microwave band signal detection range, and the method further includes:

[0057] Whether the target object is an object of a specified category is determined according to the presence or absence of the first detection signal and the second detection signal.

[0058] The infrared band signal detection range refers to the detection range of the target object movement determined by detecting the movement of the heat source using infrared rays, and the microwave band signal detection range refers to the detection range of the target object movement detected by microwaves. Correspondingly, the first detection signal refers to the signal obtained by detecting the movement of the target object by detecting the movement of the heat source, and the second detection signal refers to the signal obtained by detecting the movement of the target object using the Doppler effect as the principle. Taking the control scenario of smart home devices as an example, the moving target object may be a person or other movable objects, such as a sweeping robot, a toy car, etc. In this embodiment, the target object detection method can distinguish the movement of people or other movable objects in multiple different areas of the home. When a person enters different areas of the home, the smart home devices in the area are intelligently controlled to turn on accordingly, wherein the object of the specified category refers to a person.

[0059] The composite sensor forms an infrared band signal detection range and a microwave band signal detection range respectively. The first detection signal is a detection signal obtained by the composite sensor when detecting the movement of the target object within the infrared band signal detection range. The second detection signal is a detection signal obtained by the composite sensor when detecting the movement of the target object within the microwave band signal detection range. When the composite sensor can judge that the target object moves in different areas according to the detection result and always detects only the second detection signal but not the first detection signal, it indicates that the target object is an object other than a heat source, that is, the case where the target object is a person can be excluded. In the smart home control method implemented based on the target object motion detection method, at this time, the determination of the movement state of the target object can be ignored, and the control of the smart home devices in the overlapping area and / or the non-overlapping area can be ignored.

[0060] In the above embodiment, the composite sensor forms an infrared band signal detection range and a microwave band signal detection range respectively, so as to determine whether the target object is an object of a specified category according to the presence or absence of the first detection signal and the second detection signal, thereby improving the accuracy of the motion detection result of the target object. In the case of applying the motion detection result of the target object to the smart home control application scenario, when the object is not an object of a specified category, the control of the smart home devices in the overlapping area and / or the non-overlapping area can be ignored, which can improve the accuracy of the control.

[0061] In some embodiments, the non-overlapping area includes a first non-overlapping area and a second non-overlapping area respectively located on both sides of the overlapping area, and determining the movement state of the target object in the overlapping area and the non-overlapping area according to the presence or absence and generation time of the first detection signal and the second detection signal includes:

[0062] According to the presence or absence and generation time of the first detection signal and the second detection signal, it is determined whether the target object enters the first non-overlapping area, the overlapping area and the second non-overlapping area and the corresponding entry time.

[0063] There are multiple non-overlapping areas, which are separated by overlapping areas, so that more separated areas can be formed, and more separate areas can be controlled separately. The non-overlapping areas include a first non-overlapping area and a second non-overlapping area located on both sides of the overlapping area. The combination of determining the movement state of the target object according to the presence or absence of the first detection signal and the second detection signal and the generation time may include: only detecting the first detection signal that the user enters the first non-overlapping area, determining that the target object enters the first non-overlapping area; only detecting the first detection signal that the target object enters the second non-overlapping area, determining that the target object enters the second non-overlapping area; detecting the first detection signal that the target object enters the first non-overlapping area, and then detecting the first detection signal and the second detection signal, determining that the target object first enters the first non-overlapping area and then enters the overlapping area; detecting the first detection signal that the target object enters the second non-overlapping area The first detection signal is detected, and then the first detection signal and the second detection signal are detected, and it is determined that the target object first enters the second non-overlapping area and then enters the overlapping area; the first detection signal when the target object enters the first non-overlapping area is detected, and then the first detection signal and the second detection signal are detected, and then the first detection signal when entering the second non-overlapping area is detected, and it is determined that the target object first enters the first non-overlapping area, and then enters the overlapping area, and then enters the second non-overlapping area; the first detection signal when the target object enters the second non-overlapping area is detected, and then the first detection signal and the second detection signal are detected, and then the first detection signal when entering the first non-overlapping area is detected, and it is determined that the target object first enters the second non-overlapping area, and then enters the overlapping area, and then enters the first non-overlapping area.

[0064] In the above embodiment, the non-overlapping areas may include multiple areas, so that the positioning of target objects in more areas can be achieved through a single composite sensor. A single composite sensor can achieve differentiated control of more areas and reduce the generation of false alarms by accurately distinguishing the movement of target objects in multiple different areas.

[0065] In some embodiments, determining the movement state of the target object in the overlapping area and the non-overlapping area according to the presence or absence and generation time of the first detection signal and the second detection signal further includes:

[0066] The moving direction of the target object is determined according to whether the target object enters the first non-overlapping area, the overlapping area, and the second non-overlapping area and the corresponding entry time.

[0067] According to the relative position relationship between the first detection range and the second detection range of the composite sensor, the relative position relationship between the first non-overlapping area, the overlapping area and the second non-overlapping area can be determined. When the target object enters the above-mentioned different areas, the composite sensor correspondingly collects the detection signal of the target object moving in the corresponding area. In this way, the composite sensor can determine the walking trajectory of the target object between multiple areas and determine the movement direction of the target object according to whether the target object enters the first non-overlapping area, the overlapping area and the second non-overlapping area and the corresponding entry time.

[0068] Based on whether the target object enters the first non-overlapping area, the overlapping area and the second non-overlapping area and the corresponding entry time, determining the combination of the movement direction of the target object may include: in a relatively short period of time, detecting a first detection signal indicating that the target object enters the first non-overlapping area, and detecting the first detection signal and the second detection signal, it can be inferred that the user is in a state of continuous movement from the first non-overlapping area to the overlapping area; optionally, based on the current user's movement direction, it can be inferred that the second non-overlapping area is the target area that the target object is about to enter; when the motion detection result of the target object is applied to the smart home control application scenario, when the target object is about to enter the second non-overlapping area, the smart home devices in the second non-overlapping area can be controlled to turn on, thereby further enhancing the user's smart experience.

[0069] In the above embodiment, by determining the movement direction of the target object in different areas and predicting the next area that the target object is to enter, a single composite sensor can be used to detect the motion of the target object in more areas, accurately distinguish the movement of the target object in multiple different areas, and even predict the target area that the target object is about to enter, which is conducive to realizing the control of more application scenarios based on the prediction results and further improving the user experience.

[0070] In some embodiments, the non-overlapping area further includes a third non-overlapping area located at the end of the overlapping area, and determining the movement state of the target object in the overlapping area and the non-overlapping area according to the presence or absence and generation time of the first detection signal and the second detection signal includes:

[0071] Whether the target object enters the third non-overlapping area and the corresponding entry time are determined according to the presence or absence of the first detection signal and the generation time of the first detection signal and the second detection signal.

[0072] The non-overlapping area further includes a third non-overlapping area. Figure 3, is a schematic diagram of the detection range of the composite sensor, the first detection range is circular, the second detection range is rectangular, the first detection range and the second detection range include an overlapping area A located in the center, the first detection range includes a first non-overlapping area B1 and a second non-overlapping area B2 located on the left and right sides of the overlapping area A, and the second detection range includes a third non-overlapping area C located at the end of the overlapping area A.

[0073] In the above embodiment, the non-overlapping area further includes a third non-overlapping area, so that the positioning of target objects in more areas can be achieved through a single composite sensor. The single composite sensor can accurately distinguish the movement of the target object in multiple different areas, reducing the generation of false alarms.

[0074] It should be noted that the detection area is not fixed. Taking the composite sensor including the infrared pyroelectric sensor and the microwave radar sensor as an example, the detection area of ​​the infrared pyroelectric sensor may vary according to the focusing ability, shape and angle of the lens, and the detection range of the microwave radar sensor may vary according to the design of the antenna. Under the technical teaching of this application, the demarcation of the overlapping area and the non-overlapping area may not be limited to the following: Figure 3 Other forms shown.
