High-precision UWB modules create new ecological positioning services for digital power plants. As the basic industry of the national economy, the power industry has attracted much attention for its intelligent construction. In the newly released "14th Five-Year Plan for National Economic and Social Development of the People's Republic of China" and "Outline of Vision 2035", the importance of accelerating the construction of industrial digitalization is also mentioned. The importance of smart energy digitization cannot be overstated.
Traditional power plants are transformed into safe, environmentally friendly, efficient, and flexible smart power plants. Its digital upgrade effectively integrates technologies such as the Internet of Things, artificial intelligence, and the Internet with traditional safety production and operation control modes, providing enterprises, users, and regulatory agencies with safe production, Safety supervision, data collection and optimization of a series of intelligent and efficient application services to promote the overall digital upgrade of the industry.
High-precision positioning of UWB module intelligent management solution
The intelligent safety management of power plant personnel is an important part of digital construction. In view of the pain points and development trends of the industry, an executable high-precision personnel positioning solution is proposed to provide safer, more reliable and convenient positioning services for the digital construction of power plants.
The high-precision positioning system is mainly divided into four layers: perception, transmission, calculation, application
Perception layer: The positioning tag is bound to the positioning object, and sends the wireless UWB module signal within the specified time interval. The positioning base station receives the wireless UWB signal of the positioning tag, attaches the base station coordinates and time stamp, and transmits the attached data of the tag;
Transport layer: The positioning base station uploads data to the positioning server through wired FE, wireless 5.8G Wi-Fi or 5G;
Solution layer: The solution layer is the UWB module positioning engine software, which processes the underlying information data through the positioning engine algorithm to obtain the accurate coordinates of the positioning label;
Application layer: WPAS realizes business functions such as real-time location display, track playback, electronic fence, working hour statistics, on-the-job management, and video linkage.
The high-precision positioning management solution adopts UWB module high-precision positioning technology. By deploying positioning base stations in key areas such as the main plant, boiler floor, and booster station, operators wear positioning tags to accurately locate the positions of operators/inspections/outsourcing personnel with an average accuracy of 10cm. The scheme effectively improves the safety management efficiency of the power plant through functions such as visualization of 3D, real-time location information, inspection route planning, track playback, electronic fence, SOS alarm, and personnel count statistics, combined with the two-vote system.
Business integration to help prevent two-vote three-system electronic technology
The two-vote-three system is the most basic guarantee for the safe production of electric power enterprises. Traditional management methods lack the connection with time and space, and cannot manage and track people's behavior in real time. After high-precision positioning and two-ticket integration, a virtual electronic fence can be automatically generated, which can automatically identify entry and operation permissions based on personnel location data and information, and issue local and remote warnings to personnel without tickets or overtime. It can automatically determine whether there is a regulatory agency. The inspectors in the inspection system realize post management, record the inspection track and task progress of the inspectors, and avoid safety risks caused by personnel leakage.
In addition, through the two-way confirmation of face recognition and electronic tags, the entry and exit permissions of the area are strictly controlled, which really helps the power plant to achieve intelligent security management with visible location and controllable behavior.
Build the future based on technology and ecology
At present, UWB module high-precision positioning technology has been widely used in more than 200 domestic power companies, including five power generation groups and local power plants. Driven by the wave of industrial reform, we will further develop our own technological advantages, combine the technology and project experience accumulated in the power industry for many years, continuously expand the scope of integration of the business system, and devote ourselves to improving the intelligent safety management system of power plants and building digital power plants. new ecology.
