People perceive
The crowd density in public places is getting higher and higher, and the mass incidents are increasing day by day. The dense flow of people increases the difficulties in security and service management. The 2D panel on the left can monitor the passenger flow, display the passenger flow density and query the regional congestion index. Through the display of area map and bar chart, managers can find the accumulation of passenger flow in time and quickly conduct drainage.
Crowd density analysis uses advanced target detection, identification, tracking and other technologies to count the number and density of crowds and other characteristic indicators, monitor the safety of crowds in public places, and help us to grasp the correct crowd density data and change trend, so as to carry out reasonable security management. Through passenger flow monitoring, the manager can establish a passenger flow early warning mechanism to effectively guide and evacuate the passenger flow beyond the bearing capacity of the site.
The 2D panel on the right is for the control of internal personnel, so that managers can know the attendance of security, cleaning, guards and other front-line personnel. By reporting the progress of tasks, help managers to analyze the deficiencies of daily patrols.
Three-dimensional thermal map of passenger flow
Through the image recognition analysis of multiple cameras, a complete thermal map of the campus can be formed. It shows the degree of concentration or even crowding in a certain area of the stadium. Red indicates that there are more people, and green indicates that there are fewer people. Crowd evacuation can be considered in advance.
Check the option of perceived door to display the entrances and exits of the venue. Click the corresponding access control number to view the flow trend of the entrance and display the peak period and average flow of the entrance. Through the data presentation, the venue management personnel can efficiently and intelligently operate and maintain.
Click the camera option to jump to the layout of the camera equipment on each floor of the pavilion. The camera monitoring can carry out a full range of security monitoring and prevention of the venue and facilitate access when monitoring and collecting.
5G base station is the core equipment of 5G network, providing wireless coverage and realizing wireless signal transmission between wired communication network and wireless terminals. With the continuous development of information networks, the operation and maintenance management of venues, the implementation of equipment during events, and the stability of information and communication of staff in the venues are all inseparable from 5G network. Information panel shows the speed of the base station, connection rate, 5 g telecom users, telecommunication traffic, 5 g unicom users, mobile users, such as information, outside the venue set 5 g base stations, communications equipment, such as is not only beneficial to the museum is convenient, can also be used for network communication operations staff to understand to the activities of communication for people in the information, the use of 5 g coverage, and so on.
Real-time monitoring
The HT visualizations can be used to view the hazard warning, fire alarm ratio, personnel gathering ratio and trespass ratio. After the access of human flow data, the personnel gathering area and processing progress can be displayed in a rolling manner. Perception of the door information display, record the information of each admission personnel, to facilitate troubleshooting. Face capturing machines can be installed at the entrances and exits of the venues to form passenger flow portraits through big data analysis, so that managers can master the personnel structure. Access to the monitoring screen in the stadium, in case of problems, security personnel can quickly locate, realize real-time prediction, real-time discovery and real-time disposal.
Video fusion
Information flow digitization, coding compression, open protocol, so that the intelligent network video surveillance system and the security system of each subsystem to achieve seamless connection, and in a unified visualized management platform to achieve management and control.
Integrate multiple island systems to break the information barrier between systems. Combined with the video fusion technology, multi-channel surveillance videos can be fused, so that the original fragmented video can be viewed in a panorama in the real THREE-DIMENSIONAL scene, and the whole scene can be captured in a panorama from any required perspective, helping users to quickly overview the whole situation. The 3d scene works in cooperation with the ball and machine tracking, which can accurately locate the target area to be tracked in the scene, and drive the PTZ to control and adjust the direction and focal length of the camera to achieve accurate tracking.
The emergency response plan
Click the “Start simulation” button, the number of evacuees will change rapidly, and the line chart of waiting rescue personnel, resident personnel, real-time exit traffic and cumulative exit traffic will also change accordingly.
In terms of time, the public crisis emergency management can be divided into four stages: early warning stage, preparation stage, emergency response stage and evaluation and recovery stage. We can design the overall framework function of the system according to the simulation of emergency plan.
Visualization of simulation exercise
The emergency simulation drill system simulates the process of disaster occurrence and development, as well as the possible responses of people in the disaster environment in virtual space through the simulation of various kinds of disaster numerical simulation and numerical simulation of human behavior. Formulate special emergency plans and on-site disposal plans for all kinds of possible accidents and all hazard sources at all levels, and clarify the responsibilities of relevant departments and personnel in each process before, during, and after the event.
The task scheduling system connected to the venue replaces the traditional personnel reporting and feedback mechanism by a data-driven way. Real-time personnel task dispatching ensures timely handling of emergency alarms. HT visualized the task name, task subject, profession, task type, task level, task content, and task processing result of task scheduling, which improved the control of task processing inside and outside the stadium.
conclusion
Looking back on the 2008 Beijing Olympics, we worked hard to realize the strategic concept of “New Beijing, Great Olympics” based on the three concepts of “Green Olympics, high-tech Olympics and people’s Olympics”, which not only created a number of world-class material heritages, but also formed valuable spiritual qualities.
With the continuous development of science and technology, smart Stadium can monitor the flow of people, safety, environment and other conditions in the sports field in real time through the multi-functional linkage of three modules, namely safety management, intelligent control and big data analysis. Through HT visualization system, the online management of access control, lighting, monitoring, broadcasting and other equipment of all sports venues is realized. Integrate data with traditional elements to help enterprises change the way of profit and create digital space.
Use more active data to explore the management of minimal snap-ins. Build thousands and thousands of agents to form one large agent. From a building to a street, a district, and even a city, to comprehensively promote the digital transformation of the city.
From the perspective of national strategic layout, digital development is the main theme of economic development in the next 15 years. The 14th Five-Year Plan and the Outline of 2035 focus on “embracing the digital era and activating the potential of data elements”. In the field of infrastructure, we need to accelerate urban renewal and intelligent upgrading of traditional infrastructure, promote the transition from the Internet of everything to the intelligent link of everything, and further promote the transformation of total factor digital. Tupu complies with the trend of The Times and puts forward a lot of solutions.
The visualization solution needs the help of modern technologies such as the Internet of Things, big data, cloud computing and artificial intelligence to form a smart venue with real-time perception, scientific decision-making, efficient operation and intelligent monitoring.
Not only gymnasiums, but also archives, exhibition halls and other places can use the HT visualization technology of graphic software, combined with GIS, BIM and other technologies, to improve the work efficiency of operation and maintenance personnel and the green and intelligent development of venues and exhibition halls.
