Stepping into a new stage of "double carbon" development, China iron and steel industry has ushered in a new trend of green development. From the perspective of opportunities, it will help the steel industry achieve a higher level of dynamic balance between supply and demand, promote the transformation and upgrading of production technology, promote technological revolution, provide a new direction for intelligent development, help build a new pattern of coordinated development of steel, building materials, power generation and chemical industry, provide development space for coordinated pollution reduction and carbon reduction, deepen the concept of product life cycle, and promote the development of low-carbon standardization in the industry. In order to fully meet the digital age and enter a new stage of digital intelligence, the potential of data elements should be activated. At present, China steel industry gathers the wisdom of all parties, builds an open and win-win cooperation ecology, and promotes the intelligent transformation and upgrading of the whole industry; Iron and steel enterprises continue to deepen data utilization and focus on building a new generation of intelligent management and control centers.
Up to now, many equipments in most domestic factories operate independently and are not connected with each other, so the running status of equipment and production cycle data can not interact, and the data can not be systematically analyzed and optimized, which leads to the formation of information islands. In order to respond to the call of "Made in China 2025", the visualization components, two-dimensional configuration and three-dimensional configuration of graphics software are twin elements of intelligent steel works, such as main buildings, intelligent manufacturing workshops, operating equipment, manufacturing materials in workshops, division of operating areas, operators and so on. The visualization system connects the server to collect all kinds of data sources, and then superimposes powerful 2D and 3D engines, rich graphic components and interface design, and collects real-time data in combination with key data such as production and operation, technology, environment and safety in the factory.
By connecting MES, SCADA, ERP and other technologies, the system integrates and interacts with three-dimensional scenes to realize the deep integration of data sharing, manufacturing enterprises and digital and remote production line operation management. The model of digital twin simulation can be scaled, translated and rotated at will from multiple angles. Through the three-dimensional dynamic effect driven by real-time data, the visual effect of what you see is what you get is realized, which reflects the safety information of factory personnel more intuitively and vividly. When an alarm occurs, it can automatically locate the alarm point in the three-dimensional model and automatically pop up a window to display the alarm details, so as to realize the interconnection of people, machines, things, law and environment at the data level.
The three-dimensional personnel safety positioning system simulates the three-dimensional modeling of CSP hot rolling plant and blast furnace ironmaking plant in iron and steel plant according to the deployment position of UWB base station and video surveillance, and intuitively reflects the personnel status in their respective regions, so that production management departments and safety supervision departments at all levels in their respective regions can intuitively, quickly and comprehensively understand the dynamic information of personnel in their respective regions.
The positioning card device carried by the staff can send out SOS alarm information through manual operation. If the field personnel are in danger, the information will be fed back to the alarm record of the security interface at the first time, and the staff of the centralized control center can respond at the first time after receiving the distress information. The personnel quick navigation function supports querying and locating all online personnel, and can also browse the offline personnel list to help managers find them quickly. 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.
On the one hand, the personnel positioning function is helpful to mobilize and command field personnel and strengthen overall management; On the other hand, it is helpful to monitor the behavior track and safety information of employees and strengthen safety management. It makes up for the weak links and threats of the existing system in the factory, improves the timeliness and accuracy of business decision-making, improves the intelligent level and operational efficiency of the enterprise, and provides a strong guarantee for the safe and stable operation of the enterprise.
Starting from the digital Shuanggang Plant, this paper focuses on the one-key positioning of abnormal alarm, real-time positioning of personnel, historical trajectory tracing and alarm video linkage. All kinds of abnormal alarms can be displayed by one-click positioning, including personnel position alarm and video intelligent analysis alarm. Personnel position information can be counted by region and department, which supports one-click positioning. Managers can view the historical track of field personnel through the system, support multi-file viewing, and realize automatic video tracking according to the position of personnel. So as to meet the requirements of scheduling integration, data traceability, data transparency and intelligent operation and maintenance management.
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.
Compared with the traditional two-dimensional configuration monitoring system, the interface of three-dimensional configuration construction is more intuitive and simple, which is convenient for monitoring personnel to identify abnormal information and improve monitoring efficiency. Users can see the location distribution of cameras in the factory at a glance through the three-dimensional scene. Video can also be seamlessly embedded into the scene through the emerging video fusion technology to truly restore the real scene.
In the complex environment of digital twin steel mills, the visual scene is fully covered without dead ends, and the intelligent control technology is deeply developed and applied, so as to enhance the comprehensive capabilities of enterprises such as intelligent management and control, intelligent operation, intelligent safety monitoring, intelligent analysis and remote diagnosis, and build a future-oriented intelligent innovation management and operation mode.
