Description

Technical Field

[0001] This utility model relates to the field of intelligent lighting system technology, specifically to a lighting communication system based on UWB, which includes a lamp network access and positioning device. Background Technology

[0002] The smart lighting market is growing rapidly, with applications expanding from commercial to residential and urban lighting. However, with rapidly increasing labor costs, improving system usability and ease of installation has become a bottleneck restricting the promotion and use of intelligent systems. Simplifying the installation and commissioning process, enabling traditional lighting installers to use the equipment, is a key step in accelerating the implementation of intelligent lighting systems.

[0003] There are generally several ways to add existing devices to the network: 1. Labeling the device: A mobile phone scans the code to obtain the device's address and password, then adds the device to the gateway. This method is reliable, but requires training on-site installation and debugging personnel to be familiar with the device addition and installation process. It also requires sufficient space in the casing to affix the label, and installation is impossible if the label is damaged. 2. Built-in NFC: The mobile phone obtains the device's address and password via NFC communication. This solution is easy to debug, but requires sufficient space inside the device for installation, and the NFC antenna needs to be separated from the device's internal circuitry, increasing costs. 3. Active reporting function: The device reports its address and password to the gateway, and then uses indicator lights to determine the correspondence between the address and the device. If there are many devices, the device indicators become very complex.

[0004] The on-site lighting equipment is all installed on the roof, which is not easy to access. Therefore, the implementation process is relatively complicated, the construction is difficult, and the construction efficiency is relatively low. Utility Model Content

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a lighting communication system lamp network access and positioning device based on UWB, including a positioning terminal, wherein the positioning terminal includes: a power module, a processor, a photosensitive sensor and a UWB positioning module; the photosensitive sensor and the UWB positioning module are both connected to the processor; The power module is used to supply power.

[0007] The positioning terminal also includes a button module, which is connected to the processor and is used to input information collection commands.

[0008] The positioning terminal also includes a Bluetooth transceiver circuit connected to the processor.

[0009] The positioning terminal also includes a laser alignment module, which is connected to the processor and is used to emit laser light to assist the positioning terminal in adjusting the angle so that the photosensitive sensor is aligned with the smart lamp.

[0010] The control terminal of the laser alignment module is connected to the processor.

[0011] The positioning terminal also includes a geomagnetic sensor, which is connected to the processor and is used to acquire the azimuth and pitch angles of the positioning terminal and send them to the processor.

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] like Figure 1 As shown in the figure, this utility model embodiment provides a lighting communication system lamp network access positioning device based on UWB, including a positioning terminal. The positioning terminal includes: a power module, a processor, a photosensitive sensor, and a UWB positioning module; both the photosensitive sensor and the UWB positioning module are connected to the processor; the power module is used to supply power, the photosensitive sensor is used to collect the flashing light signal emitted by the smart lamp and send it to the processor, and the UWB positioning module is used to collect location information and send it to the processor; the processor is used to send the collected flashing light signal and location information to a gateway.

[0016] Specifically, in this embodiment, the positioning terminal further includes a button module, which is connected to the processor and used to input information collection commands.

[0017] Furthermore, such as Figure 2 As shown in this embodiment, a lighting communication system based on UWB, including a lamp network access and positioning device, further includes a gateway, a mobile phone, and a system platform. In this embodiment, the positioning terminal also includes a USB interface, which connects to the mobile phone or a power bank. The positioning terminal can be powered by the mobile phone or power bank and enables bidirectional communication with the mobile phone. Specifically, the positioning terminal communicates with the mobile phone via USB, the mobile phone communicates with the system platform via a mobile network, and the system platform communicates with the gateway via an Ethernet or 4G network. The gateway is communicatively connected to the smart lamp. The positioning terminal sends the collected lamp information to the mobile phone, which in turn connects to the system platform via the mobile network and sends the lamp information to the system platform. The system platform connects to the gateway via an Ethernet or 4G network and sends the information to the gateway. The gateway then communicates with the smart lamp, enabling remote control of the smart lamp.

[0018] Specifically, such as Figure 3 As shown in this embodiment, the gateway includes a gateway processor, a communication circuit, and an Ethernet communication module. The gateway connects to the smart lighting fixture via the communication circuit and connects to the system platform via the Ethernet communication module. Furthermore, the gateway also includes a Bluetooth interface and a Wi-Fi interface, allowing it to connect to other smart devices, such as wireless smart lighting fixtures, via either the Bluetooth or Wi-Fi interface.

[0019] Furthermore, in this embodiment, the positioning terminal also includes a laser alignment module, which is connected to the processor and is used to emit a laser to assist the positioning terminal in adjusting the angle so that the photosensitive sensor is aligned with the smart lamp.

[0020] Furthermore, in this embodiment, as Figure 1 As shown, the positioning terminal also includes a geomagnetic sensor, which is used to acquire the azimuth and pitch angles of the positioning terminal. When the positioning terminal is not positioned directly beneath the light fixture, the three-dimensional coordinates of the light fixture relative to the positioning terminal are determined by combining the azimuth and pitch angles measured by the geomagnetic sensor with the height of the light fixture. This, along with the position information obtained from the UWB positioning module, ultimately determines the physical location of the smart light fixture. The geomagnetic sensor simplifies the measurement process, allowing measurements to be taken even without the positioning terminal being positioned directly beneath the light fixture.

[0021] Specifically, the UWB positioning module, in conjunction with two or three UWB base stations, can obtain the spatial coordinates of the positioning terminal.

[0022] Furthermore, in this embodiment, the control terminal of the laser alignment module is connected to the processor.

[0023] The working principle and steps of this utility model are as follows: Figure 3 As shown, during use, the smart light fixture can be controlled to flash and emit light via a smart gateway, sending information such as its network address and password, or a summary and compressed version of that information. The installation personnel place the positioning terminal under the smart light fixture from which the information is to be acquired. The flashing light emitted by the light fixture reaches the photosensitive sensor, which then sends the received light to the processor. The processor demodulates the light to obtain a two-digit encoded information related to the light fixture's network address and password. Simultaneously, pressing the button module activates the UWB positioning module, which acquires the physical location of the positioning terminal and sends it to the processor. The geomagnetic sensor measures the azimuth and elevation angles of the positioning terminal and sends them to the processor. The processor, combining the physical location of the positioning terminal, determines the accurate physical location of the smart light fixture. It then associates and saves the physical location, network address, and password information of the smart light fixture, and subsequently sends it to a mobile phone via USB communication. The mobile phone, equipped with an app, can use the mobile network to send the information to the system platform. Finally, the system platform sends the information to the gateway, enabling the light fixture to join the network and be located. In addition, the laser alignment module is located next to the photosensitive sensor, and its laser emission direction is perpendicular to the photosensitive surface of the photosensitive sensor. The laser emitted by the laser alignment module is perpendicular to the light fixture, which can help construction personnel adjust the position of the positioning device so that the photosensitive sensor can receive information.

[0024] In summary, this utility model provides a lighting communication system based on UWB for lamp network access and positioning. It uses a UWB positioning module to obtain the physical location of the lamp, and a photosensitive sensor to acquire the lamp's luminous information, thereby associating it with the lamp's network address, password, and other information to achieve network access and positioning. During construction, no climbing is required, greatly simplifying the installation and debugging process of intelligent lighting equipment, and it also has extremely high safety and reliability, making it widely applicable. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
