Solution Description: At present, the BeiDou satellite system is primarily focused on addressing the following issues in the petrochemical industry:

• Inaccuracy in personnel and vehicle positioning: It is challenging to accurately and in real-time determine the exact location of both internal and external personnel and vehicles. In the event of an unexpected safety incident, it becomes hard to promptly ascertain the location of individuals and devise an effective rescue plan.

• Weak operation safety assurance: It is difficult to control unauthorized access of personnel and vehicles into areas with significant hazard sources, high-risk installations, special operation zones, tank areas, loading and unloading platforms, maintenance areas, and other key supervision areas.

• Room for improvement in intelligent management: Relying on manual supervision, it is not possible to effectively manage personnel attendance, work shift transitions, work hour statistics, and other aspects of work status. It is also challenging to determine whether inspection personnel have followed prescribed routes and inspection points. By integrating satellite, UWB, and Bluetooth positioning technologies, we can achieve seamless indoor-outdoor positioning, two-and three-dimensional map presentation, electronic fencing, safety warnings, location tracking, trajectory playback, and other functions. This meets the information management needs of petrochemical enterprises and significantly enhances the efficiency of safety production.
