Qingdao stadium has made headlines again, but it has nothing to do with sports

The total land area of Qingdao Pingdu Olympic Sports Center is 37.321 Thousands of square meters （ About us 559.81 mu ）, The total building area is 10.06 Thousands of square meters , afforested area 10.77 Thousands of square meters , Area of road square 22.92 Thousands of square meters , There are parking spaces in the park 956 individual , On the ground 690 individual 、 Underground 266 individual .

Take Qingdao gymnasium as the carrier , Digital twin gymnasium and its surrounding facilities and environment . Through intelligent building management tools , Realize the monitoring of equipment on each floor . use HT Lightweight 3D modeling technology , 1：1 High simulation simulates the interior and exterior of the gymnasium , Present a colorful Gymnasium . The walls of the building are designed to be transparent , Indoor and outdoor seamless switching .

Stream of people perception

Frequent stampede accidents , Make the business field 、 The demand for people flow statistics and prediction in the field of traffic control and public safety is gradually increasing . However, the current statistical methods of people flow often use the traditional mechanical or human statistical methods , Not only is it inefficient , Interfere with normal personnel walking and flow speed . Integrate the large passenger flow risk insight system with the intelligent traffic dispatching system , It can sense the flow of people around the road in real time 、 Traffic flow , Timely dispatch security personnel for guidance .

The traditional method of people flow statistics is through the use of large gates 、RFID The card reader and infrared device calculate the number of people . Take advantage of the traditional HOG+SVM The classifier method detects the target , recycling KCF The method of correlation filtering is used to realize multi-target tracking . Transfer the data collected by such equipment to HT Visualization screen , It is convenient for managers to allocate personnel .

Check the heat map 、 Perception door 、 camera , You can view the distribution location of personnel gathering area and related equipment .

Three dimensional thermal diagram of passenger flow

Through camera calibration and coordinate conversion , The pedestrian coordinates on the image can be realized , And the coordinates of the real physical world , So as to realize the generation of people flow heat map on the map , Realize more intuitive display of people flow distribution . Analyze the personnel gathering in the passenger flow heat map , Through long-term statistical analysis, the thermal distribution of passenger flow , It can be analyzed by using the time dimension human flow thermodynamic diagram , To calculate the main walking routes of the people in the gymnasium , Carry out orderly commodity display and moving line planning , It is beneficial for the gymnasium to promote the increase of consumer consumption times and consumption amount .

Visualization of pedestrian flow at the entrance and exit

Check the option of perception door , It can display all entrances and exits of the venue , Click the corresponding entry / exit No , Check the flow trend at the inlet , Display information such as peak period and average passenger flow at the entrance . Equipped with face recognition equipment, it can judge the gender and age of the entry and exit personnel , At the same time, it can also create portraits of people in various areas .

Visualization of communication equipment

ITU Defined 5G Eight key performance indicators , Among them, the high rate 、 Low latency 、 The big connection becomes 5G The most prominent feature , The user experience rate reaches 1Gbps, The delay is as low as 1ms, The user connection capacity reaches 100 Wan Lian / Square kilometers .HT 2D The information on the panel shows the rate of the base station 、 Connection rate 、5G Number of telecom users 、 Telecom traffic 、5G Unicom users 、 Mobile users and other information .

Real-time monitoring

HT Based on HTML5 Standard component library , It's seamless HTML5 Various multimedia functions , Support the integration of various video resources to form a unified video stream , Can be found in 2D、3D Mark the camera object on the situation map and associate it with its video signal source , Call the corresponding monitoring video through scene interaction , Meet the real-time situation awareness of the scene by the operation and maintenance personnel 、 Historical data backtracking comparison 、 Emergency response plan and other monitoring requirements .

HT Support video fusion , take 2D Video image fusion into the scene 3D In the model , Provide users with intuitive video images and simple view control . Through indoor surveillance video and 3D scene overlay display , You can see the scene as if you were there . And it can realize automatic video inspection of critical path , Key areas focus on advanced functions such as fast target locking , Provide intuitive and accurate assistance for daily management and emergency handling .

Emergency plan

The gymnasium serves as a place for people to gather , Emergencies happen from time to time , Only simulate the evacuation route in advance , Make an emergency plan , Only in this way can we avoid chaos in the face of danger . Click the start simulation button , The number of evacuees is changing rapidly , Wait outside for rescue workers 、 Resident 、 Real time number of people passing through the exit 、 Broken line diagram of cumulative number of people passing through the exit , There will be corresponding changes . The best escape route can be determined through multiple simulations , Ensure personnel safety .

Human task scheduling

Access to the task scheduling system of the venue , In a data-driven way , Replace the traditional personnel reporting and feedback mechanism . Dispatch through real-time human task scheduling , Dispatch personnel to handle in time , Ensure the timeliness of emergency alarm processing .HT Visually display the task name of task scheduling 、 Mission theme 、 Belong to the major 、 Task type 、 Mission level 、 Task content, task processing results and other information , Improved the control of task handling inside and outside the venue .

Qingdao gymnasium is the host venue for various sports events in Qingdao , The crowd is dense , However, its leading degree of intelligence can better realize personnel management and control . Use intelligent lighting system and fire protection system , It is conducive to the implementation of energy conservation and emission reduction measures . future , The venue will continue to explore “5G+ Digital intelligence sports ”,“5G+ Smart skiing ” Projects such as , utilize 5G Technology enabled visual service assurance platform , Help the gymnasium realize dispatching and command 、 Emergency security and epidemic prevention and control .

Again , Beijing 2022 The Winter Olympic Games and the winter Paralympic Games will open soon , Bird nest 、 The water cube 、 Wukesong …… these 14 The impressive venues of the Beijing Olympic Games years ago will be unveiled again .
