As an industry-leading UWB high-precision positioning research and application enterprise, the self-developed UWB high-precision positioning system is suitable for different complex environments and achieves different positioning business needs. Through the real-time and accurate positioning of personnel and vehicle materials, extended functions such as electronic fence, intelligent inspection, track playback, regional alarm, video linkage, and attendance management are realized. At present, diversified positioning application solutions have been implemented in many fields:

1. Electric energy

In order to comprehensively promote the informatization and standardization of safety management in the power industry, a power personnel positioning management system was launched based on UWB positioning technology. By deploying a positioning base station in the power plant/substation operation area, the operator wears the positioning tag, and the position information of the operator is displayed on the positioning engine with zero delay, effectively supervising and managing the safe operation of the operator in the daily work process, and ensuring the work target of safe production . The system integrates functions such as personnel attendance, two-vote fusion, SOS alarm, video linkage, alarm release, and auxiliary search and rescue.

2. Petrochemical

For the high-risk chemical industry, personnel safety management is particularly important. The chemical personnel positioning management system based on the high-precision centimeter-level UWB positioning solution technology fundamentally solves the problems of difficulty in personnel, inspection and security. Explosion-proof base stations are installed in areas such as the refinery area of the chemical plant and the explosion-proof control center. Personnel wear explosion-proof labels to accurately locate personnel in real time, with an average positioning accuracy of 30cm; in case of emergency, operators can use the SOS button on the label for emergency rescue; The customized electronic fence realizes two-way alarm for violations; in addition, the system can also integrate intelligent safety management such as video linkage, intelligent inspection control, division of labor and attendance to ensure personnel safety management and reduce accidents.

3. Smart Manufacturing 4.0

With the advent of Industry 4.0, traditional manufacturing is moving towards intelligence and informatization, facing the strong market demand for intelligent manufacturing. Combined with the latest IoT positioning technology, a factory positioning management system based on high-precision centimeter-level UWB positioning solution technology was launched. By deploying indoor positioning base stations in the factory, personnel/materials wear positioning tags to accurately locate the location information of factory personnel/materials in real time, with an average positioning accuracy of 10cm. Through accurate location information, it can realize intelligent management of factory materials, process optimization, efficiency and KPI analysis, make factory control more intelligent, and help Industry 4.0 improve management efficiency.

4. Tunnel gallery

In order to meet the safety control of construction personnel and vehicles during tunnel/pipe tunnel construction, combined with the new IoT positioning technology, a tunnel/pipe tunnel location management system based on UWB technology was launched. The base station adopts one-dimensional positioning deployment, and the coverage distance of a single base station can reach 300 meters; personnel and vehicles should wear high-power positioning tags to sense the location information and activity status of personnel and vehicles in the tunnel/pipe gallery, with an average positioning accuracy of 10cm. System integration can fully grasp the trajectory of personnel/vehicles; meet the needs of personnel intelligent attendance; in emergency situations, two-way alarm can be realized; relevant video sensors can display on-site conditions on a large screen, which can more effectively improve operational efficiency and ensure personnel safety at the same time .
