Description

Technical Field

[0001] This utility model relates to a multifunctional integrated lamp based on invisible light, belonging to the field of integrated positioning lighting technology. Background Technology

[0002] In enclosed environments such as medical facilities, data centers, and communication hubs, which are susceptible to electromagnetic interference, traditional positioning technologies present numerous challenges. Satellite positioning relies on satellite signal transmission, which is easily disrupted by building structures within enclosed spaces and is also prone to interference in strong electromagnetic environments, leading to inaccurate or even failed positioning. Base station positioning technology suffers from extremely low accuracy, with positioning errors reaching hundreds of meters or even kilometers, failing to meet the precise positioning requirements of medical facilities and data centers.

[0003] While Wi-Fi and Bluetooth positioning are commonly used indoors, their signals are easily interfered with by other electronic devices in complex electromagnetic environments, leading to signal attenuation, distortion, and increased positioning errors. Furthermore, they require the pre-deployment of numerous hotspots or beacons and the establishment of complex signal fingerprint databases, resulting in high maintenance costs. RFID positioning technology suffers from poor real-time performance, requiring the target to be close to the reader for signal reading and unable to track the dynamic position of moving targets in real time. Ultrasonic positioning technology is significantly affected by spatial obstacles; signals are easily reflected or scattered by obstacles, resulting in short propagation distances, and environmental noise can also interfere, leading to poor positioning results. Inertial navigation positioning technology is expensive; high-precision inertial navigation equipment is costly, and errors accumulate over time, requiring periodic calibration, making it unsuitable for cost-sensitive scenarios requiring continuous and accurate positioning.
