The positioning is to determine the position of the wearer; as shown in fig. 2, in a room, for example, a house, there are a plurality of rooms, each room can be defined as an indoor space, wherein each indoor space can be provided with one or more intelligent lighting devices 201 to 206, the intelligent lighting devices 201 to 206 can be connected to each other through their respective communication units to form a communication network, and the communication network is used to communicate information of the intelligent lighting devices in each room; it should be noted that, in other embodiments, only one intelligent lighting device may be set in the whole house, and the wearer may be located through the intelligent lighting device.
In an embodiment of the present invention, each of the intelligent lighting devices is divided into two types, one is a main lighting device, and the other is an auxiliary lighting device. The auxiliary lighting device may be a simplified configuration as compared with the main lighting device, that is, a part of functional components is reduced, for example, as shown in fig. 3a and 3b, the reduced part of functional components may be a camera unit, or a sound pickup unit, a speaker, a display screen, or the like, so that the cost of the auxiliary lighting device can be reduced, and a large amount of storage resources occupied by information collected by the auxiliary lighting device can be avoided, thereby reducing the burden of the device.

As can be seen from the embodiment illustrated in fig. 3A and 3B, the primary lighting device has an image pickup unit, while none of the other secondary lighting devices has an image pickup unit; in the embodiment of fig. 2, the intelligent lighting device 201 in the living room is the main lighting device, and the camera unit thereon can obtain a larger monitoring range; after multiple positioning, image acquisition can be carried out by starting the camera shooting unit through the main lighting equipment, so that monitoring is realized; the intelligent lighting devices 202-206 in the indoor spaces such as the master bedroom, the three bedrooms and the kitchen are auxiliary lighting devices and are responsible for positioning.
Fig. 4 is a schematic structural diagram of the communication network according to the embodiment of the present invention. In this embodiment, the main lighting device and each of the auxiliary lighting devices 1 to K are respectively in communication connection with one or more of the intelligent wearable devices 1 to N, and the main lighting device and each of the auxiliary lighting devices 1 to K are in communication connection through a routing device to form a communication network; preferably, the routing device may be in communication connection with a cloud device, and the cloud device is equipped with a management system to receive data in the communication network (for example, positioning data of the intelligent lighting device on the wearer, captured image data, or body state information of the wearer collected by the intelligent wearable device); the management system may also generate control instructions and send the control instructions to the intelligent lighting devices for remote control, such as controlling the adjustment of lighting parameters, sound signal acquisition, image acquisition, voice playing, or image display.
In an embodiment of the invention, the processing unit may first position the position of the wearer through the wireless signal, and then perform the second positioning on the wearer through the environmental information; for example, the processing unit positions the position of the wearer according to the wireless signal strength values of the first wireless transmission module and the intelligent wearable device, and performs second positioning according to the environmental information when the position of the wearer is determined to be located in the indoor space where the intelligent lighting device is located.
Specifically, by means of a first positioning mode of the wireless signal strength value, for example, the processing unit compares whether the strength value of the wireless signal between the current first wireless transmission module and the intelligent wearable device is greater than a threshold value; if the number of the intelligent lighting devices is larger than the preset value, the wearer can be considered to be located in the indoor space where the intelligent lighting devices are located; or, preferably, the intelligent lighting devices are respectively distributed in each indoor space, the intelligent lighting devices are in communication connection with each other through the communication unit to form a network, each intelligent lighting device can send the current wireless signal intensity value between the intelligent lighting device and the intelligent wearable device to other intelligent lighting devices, each intelligent lighting device compares the wireless signal intensity value of the wireless communication between the intelligent lighting device and the intelligent wearable device with the wireless signal intensity values of other intelligent lighting devices to determine the maximum wireless signal intensity value, and uses the corresponding intelligent lighting device as a target device, so as to complete first positioning of the target device on the intelligent wearable device (namely, judge that the intelligent wearable device and a wearer are located in the indoor space where the target device is located), and then complete second positioning.
Specifically, the second positioning is performed through the environment information, for example, the processing unit compares whether a volume value of a sound signal (e.g., generated by walking, speaking, and other behaviors) of the wearer, which is collected by the current sound pickup unit, is greater than a volume threshold value; if the number of the intelligent lighting devices is larger than the preset value, the wearer can be considered to be located in the indoor space where the intelligent lighting devices are located; or, preferably, the communication network composed of the plurality of intelligent lighting devices may be utilized to obtain one of the volume signals with the largest volume value, and then the corresponding intelligent lighting device is used as the target device, so as to complete the first positioning of the target device on the intelligent wearable device (i.e., determine that the intelligent wearable device and the wearer are located in the indoor space where the target device is located), and then complete the second positioning.
Through the first positioning, a user wearing the intelligent device can be roughly judged to be located in which room, the specific direction of the user can be more accurately positioned in the room through the second positioning, and meanwhile, whether the first positioning is wrong or not can be verified through the second positioning.
It should be noted that, in other embodiments, the positioning by the environment information may be used as the first positioning method, and the positioning by the wireless signal strength value may be used as the second positioning method, which is not limited to the above examples.
After the position of the wearer of the intelligent wearable device is determined through the multiple positioning, the intelligent lighting device can monitor the wearer by using the positioning result.
In one embodiment, in a communication network formed by the main lighting device and the auxiliary lighting devices, if one auxiliary lighting device has performed multiple positioning on a wearer to obtain an accurate position of the wearer, a message is sent through the communication network to inform the main lighting device, and the position of each intelligent lighting device can be known after being arranged in a corresponding indoor space, so that the main lighting device starts a camera unit of the main lighting device to perform image acquisition towards the position of the positioned wearer when acquiring the message; when monitoring is achieved, the position of the wearer in the image can be identified through an image identification technology, so that repositioning can be increased, and accuracy is higher.
In another embodiment, the lighting function of the intelligent lighting device may also be used for assisting positioning, specifically, the intelligent lighting device determined as the target device may change its lighting parameters to make the lighting condition of the first indoor space where it is located different from that of the second indoor space other than the first indoor space; the lighting parameters include: brightness and/or color temperature.
For example, a smart lighting device a1 is provided in room a and a smart lighting device B1 is provided in room B, which adjusts its lighting parameters when a1 is positioned such that the wearer is in room a, which is different from room B in lighting conditions, e.g., room a is bright and room B is dark; or, room a is illuminated with warm color light, room B is illuminated with cool color light, and so on.
The main lighting equipment starts the camera shooting unit to collect images, and distinguishes the room A where the wearer is located according to the characteristics of different lighting conditions in the images, such as different brightness and colors of the room A and the room B, and then the camera shooting unit turns to the room A and is used for collecting the images of the room A; optionally, the first wireless transmission module is configured to send the image of the wearer to the outside, for example, to the cloud device through a communication connection, or may send the image to a pre-associated mobile terminal (a mobile phone, a tablet computer, or the like) through accessing a mobile communication network (2G/3G/4G, or the like), and the user may view the image at the mobile terminal.
The communication network formed by combining the intelligent lighting device and the intelligent wearable device can form application schemes beneficial to the health of a wearer.
For example, in an embodiment of the present invention, the first wireless transmission module is further configured to receive, from the smart wearable device, the collected physical sign information of the wearer, such as blood pressure, heart rate, and the like; the communication unit is used for sending the physical sign information outwards, for example, sending the physical sign information outwards in a wired mode or a wireless mode, so that the physical sign information is transmitted to the management system through a communication network, the management system stores the physical sign information, and big data analysis is carried out through the physical sign information accumulated in a period of time so as to obtain the health condition of a wearer, and the health monitoring mode is vital to patients with chronic and serious diseases, such as heart diseases.
Through the positioning and monitoring mode in the embodiment, the anti-theft and monitoring of the weak people such as the old, children and the like can be realized.
For example, the intelligent lighting device monitors the continuous disconnection time of the connection between the intelligent lighting device and the intelligent wearable device, and when the disconnection time exceeds a preset threshold value, the intelligent lighting device judges that a resident is not at home, and then the camera unit is started to perform anti-theft monitoring; optionally, the sound pickup unit may also be turned on to monitor the abnormal sound; when the situation (such as theft) that the preset strange people enter is judged to be met according to the information collected by monitoring, an alarm signal communication unit is generated to send alarm information outwards, the alarm information can be converted into information in a telephone communication network by voice gateway equipment to carry out dialing 110 alarm, and can also be sent to residents or mobile terminals of the residents through a mobile communication network.
