The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0052] Before the embodiments of this application are described in detail, some related technologies involved in the embodiments of this application are described first, as follows:

[0053] Bluetooth Mesh networking: Bluetooth Mesh networking is a wireless network structure designed based on Bluetooth Low Energy (BLE) technology. It allows multiple Bluetooth devices to form multi-to-multi connections and communications, thereby creating an ad-hoc network that can be extended to a large area and accommodate thousands of nodes. In a Bluetooth Mesh network, each device can act as a sender, receiver, or even a relay node for message propagation in the network. In this way, even if there is no direct radio communication link between two devices, the message can be relayed through other devices in the network to ensure reliable propagation of information throughout the network.

[0054] IoT energy-saving lamps: refer to LED lighting fixtures with networking capabilities, brightness adjustment, remote control, and occupancy sensing functions. The energy-saving lamps referred to in this article are generally applied to public places such as underground parking lots, office areas, and production workshops.

[0055] Bluetooth beacon: is a device based on Bluetooth Low Energy (BLE) technology. It does not require a Bluetooth connection and can communicate with other Bluetooth devices within a certain range. The Bluetooth beacon periodically broadcasts specific data packets containing its own identifier to the surrounding area. These data packets usually contain information such as UUID, broadcast name, MAC address, and battery level.

[0056] RSSI: Received Signal Strength Indication, signal field strength indication.

[0057] RSSI-based positioning: The positioning technology based on the received signal strength (RSSI) estimates the distance between the receiving end and the transmitting end by measuring the strength of the signal received at the receiving end. By measuring the distances between the transmitting point and multiple receiving points with known coordinates, the coordinate value of the transmitting point is calculated.

[0058] Currently, there are existing Internet of Things energy-saving lamp products and Bluetooth beacon positioning products, but these two types of products are generally independent of each other and are installed, deployed, and used separately. The Internet of Things energy-saving lamp generally integrates a control unit, a communication module, and sensors to achieve functions such as networking, remote control, and automatic adjustment of the lamps. The Bluetooth beacon positioning system has multiple positioning methods. One of the passive positioning methods includes a Bluetooth positioning base station and a Bluetooth beacon. In this positioning method, the Bluetooth positioning base station is fixedly deployed indoors and continuously scans the surrounding Bluetooth signals. When a mobile Bluetooth beacon carried by a person or a vehicle passes by, the Bluetooth positioning base station receives the Bluetooth beacon data and transmits it back to the server via wired, WiFi, 4G, etc. After being solved by the background, the position information of the person or vehicle carrying the Bluetooth beacon is obtained in real time.

[0059] Therefore, some embodiments of the present application provide a Bluetooth Mesh Internet of Things energy-saving lamp with Bluetooth beacon positioning function, which can, on the basis of providing the functions of a conventional Internet of Things energy-saving lamp, simultaneously realize the functions of scanning Bluetooth beacon signals and uploading beacon data through the Bluetooth Mesh network, and obtain the position information of the Bluetooth beacon through the calculation of the background server. The energy-saving lamp device realizes the positioning function through the lighting system, avoiding the repeated construction and investment of the positioning system and having good economic benefits.
