1) Scenario requirements
The power plant used to adopt traditional management methods, and there are many problems such as big risks in the safety management of outsourced personnel, inability to effectively supervise and count the arrival and arrival of personnel, the reliability of supervision and prevention in high-risk operation scenarios or key areas cannot be effectively guaranteed, extensive management of plant equipment and equipment with loopholes that have not been inspected, and lack of real-time monitoring of external vehicles and personnel. Therefore, it is necessary to use high-precision positioning technology for real-time management. However, at the same time, the power energy operation scenario not only has the characteristics of high electromagnetic radiation and high shielding, but also has a large operating range and a complex environment, and there are problems such as difficult wiring and high cost of weak current.
2) Solution ideas
In view of the above demand situation, through the combination of 5G network communication and UWB high-precision positioning, give full play to the scale advantages of operators' 5G indoor network construction, and provide a virtual wireless private network for energy and power plants through 5G network communication, MEC edge computing and slicing capabilities. End-to-end security and high reliability can be achieved from the terminal to network access and factory applications. At the same time, 5G base stations support the fusion deployment of positioning equipment, and two grids of the communication network and positioning network are deployed at one time, and the positioning system fully reuses the power supply resources, transmission resources and later maintenance resources of the 5G base station, perfect merger and construction, and save costs.
3) Description of application scenarios
Location map service, showing the geographical structure of the entire power plant, the entire power plant booster station, turbine platform, barge pier and other regional layout can be clearly presented to the user.
Real-time track display, plant personnel, equipment running track real-time tracking, and backtracking. Can realize the power plant personnel tracking, tool tracking, foreign vehicle tracking.
Electronic fence alarm, in the dangerous area of the power plant, set up electronic fence, when near the area, automatically trigger alarm information.
Security camera linkage, the camera real-time monitoring of the surrounding environment, multi-target multi-picture tracking the designated person or item at the same time, the client's WEB browser access to the camera real-time video picture, tracking the designated person or item real-time location and the camera head shooting area linkage, LED large screen split screen real-time dynamic display of the designated person or item linkage camera video linkage picture, without manual setting, you can track and view the video of the corresponding weekend environment in the course of action.
Automatic attendance and working hour statistics, power plant staff to work the factory automatically attendance record, to achieve automatic attendance.
Automatic inspection management, according to the time range, department, personnel, inspection task, inspection route multidimensional statistics output; The time of personnel entering and leaving the inspection site is fully recorded; The inspection result is exported to an EXCEL file as an important basis for quantitative management and performance assessment.
Through the fusion application of UWB positioning technology and 5G, real-time positioning of power energy personnel, vehicles, tools, etc., and real-time location data display the location information of people, vehicles, and objects in the control center of power energy enterprises, combined with electronic fence, emergency rescue, intelligent scheduling and other functions. The real-time positioning of the generated position can first display the position of various elements intuitively, which is convenient for the managers of electric power energy enterprises to supervise various production elements. The open location API interface of the integrated positioning system can consider seamless docking with the existing system to achieve intelligent and accurate control of regional operation management of the power plant, high-risk operation monitoring, on-duty management, inspection process management, tools management and real-time vehicle trajectory monitoring.
