Abstract

The invention discloses a method and system for accurately positioning the position of a person in a smart home. The method comprises the following steps: installing a radar module in a room; installing an information transfer module in the room; establishing connection between the edge service middleware and the information transfer module; enabling the radar module to acquire personnel position information and report the information to the information transfer module; enabling the information transfer module to encrypt the personnel position information through the encryption module and then transmit the personnel position information to the edge service middleware; and enabling the edge service middleware to process the received personnel position information to obtain the coordinate position of the personnel relative to the single radar, then perform world coordinate conversion processing, and finally output the whole-house world coordinates of the personnel. According to the invention, based on the millimeter wave radar technology, position information of a user in a family is subjected to acquisition, encryption transmission, data analysis and the like, and accurate positioning of a personnel position is finally realized through whole-house world coordinate conversion, so that a more close-fitting intelligent service is provided for people, and the system has a wide application scene.

Example Embodiment

[0027] Example 1:

[0028] see figure 1 , this embodiment discloses a method for accurately locating a person's position in a smart home, including the following steps:

[0029] S1: Install the radar module in the room to ensure that it can cover the entire range of the room.

[0030] Specifically, the radar module includes a civilian radar module based on millimeter wave radar technology. The radar module is installed on the wall of each room according to the overlooking angle, preferably at a 45-degree angle of the wall corner, and ensures that it can cover the entire range of the room.

[0031] S2: Install an information transfer module in the room.

[0032] Specifically, the information transfer module can be installed anywhere in the room, but in order to ensure the transmission efficiency of Bluetooth, the radar module and the information transfer module should not exceed 6 meters, and there should be no partition between them as much as possible.

[0033] S3: Establish the connection between the edge service middleware and the information transfer module.

[0034] Specifically, the edge service middleware is an existing technology, which is equivalent to the edge computing middleware. The edge service middleware and the information transfer module communicate information through the TCP/IP network protocol. The edge service middleware acts as the server, and the information transfer module acts as the client. After the information transfer module is powered on, it actively connects to the server of the edge service middleware. The edge service middleware sends a white list of Bluetooth devices, that is, the Bluetooth address of the radar module that the information transfer module needs to connect to; after receiving the white list of Bluetooth devices, the information transfer module scans and connects according to the Bluetooth address in the white list.

[0035] S4: The radar module collects personnel location information and reports it to the information transfer module.

[0036] Specifically, the radar module reports the collected personnel location information to the information transfer module through Bluetooth communication.

[0037] S5: The information transfer module encrypts the personnel location information through the encryption module and transmits it to the edge service middleware.

[0038] S6: The edge service middleware processes the received personnel position information to obtain the coordinate position of the personnel relative to a single radar.

[0039] Specifically, the edge service middleware performs data packet unpacking and data analysis processing on the received data packets to obtain the coordinate position of the person relative to the radar (single radar).

[0040] S7: The edge service middleware performs world coordinate conversion processing on the coordinates relative to a single radar, and finally outputs the world coordinates of the person in the whole room. The coordinate origin can be located at the upper left corner of the house type.

[0041] Preferably, the edge service middleware runs on the smart TV background as an application program; the encryption module runs on the smart TV and the information transfer module as an application program.

[0042] Through the above steps, the position of the user in the home can be precisely positioned, and then intelligent services based on the position can be provided.

Example Embodiment

[0043] Example 2

[0044] This embodiment discloses a system for accurately locating personnel in a smart home, including a radar module, an information transfer module, an encryption module, and an edge service middleware.

[0045] The radar module includes a civilian radar module based on millimeter-wave radar technology. The radar module is installed in each room and must ensure coverage of all locations in the room.

[0046] The information transfer module is a hardware module. The information transfer module can be installed anywhere in the room, but in order to ensure the transmission efficiency of Bluetooth, the radar module and the information transfer module should not exceed 6 meters, and there should be no partition between them.

[0047] The radar module reports the collected personnel location information to the information transfer module through Bluetooth communication. The information transfer module is used to receive the personnel location information collected by the radar module, encrypt it through the encryption module and transmit it to the edge service middleware.

[0048] The edge service middleware and the information transfer module carry out information communication through the TCP/IP network protocol. The edge service middleware is used to process the personnel position information transmitted from the information transfer module, and combine the coordinates of all individual radars for world coordinate conversion processing, and finally Output the person's whole-room world coordinates.

[0049] Preferably, the edge service middleware runs on the smart TV as an application; the encryption module runs on the smart TV and the information transfer module as an application.
