Based on UWB positioning base station or other positioning hardware, the real-time positioning visualization function of employees in the factory is realized in three-dimensional scene. By deploying a visual management system in the centralized control center, managers can monitor the position of on-the-job personnel in the factory in real time, and can intuitively view employee information, contact information, action trajectory and other data through scene interaction.
Visually build a visual scene with no dead angle and full coverage in the complex environment of thermal power plants, deeply develop and apply intelligent power generation control technology, improve the comprehensive capabilities of power generation enterprises such as intelligent management and control, intelligent operation, intelligent safety monitoring, intelligent analysis and remote diagnosis, and build a future-oriented intelligent coal-fired power generation innovative management and operation mode.
In the three-dimensional scene of the factory, video monitoring points are set indoors and outdoors, and their positions are displayed with obvious icons. In this case, the monitoring equipment is used to identify the behavior of personnel, and can capture and alarm violations such as wearing safety helmet, overalls and answering the phone, and record them in the camera alarm record. The monitoring points with alarm information will have obvious alarm effect, which supports managers to click to view real-time monitoring images and capture records in time. Integrate the equipment alarm information of each subsystem and display all alarm information in the visualization system.
Under the new power system, the operation of power grid gradually presents the characteristics of intelligence and digitalization. With the development of "source-network-storage integration" operation, cloud computing, big data, power internet of things, edge computing and other technical means in "cloud-big things moving to the edge of intelligent chain" are urgently needed, so that the power grid system is equipped with cloud solutions with massive data processing and analysis capabilities and highly intelligent decision-making capabilities.
