There are some typical difficulties in the construction of smart venues:
First, the personnel movement line is complex. The use of venues shall meet the distributed space and route management of different types of personnel, including more than ten kinds of personnel information such as athletes, spectators, referees and media, and route confirmation of corresponding activity areas. And ensure that the control of different types of personnel during the competition is completely isolated.
Second, there are many kinds of equipment. There are tens of thousands of venue access equipment, and the coordination and linkage logic of different equipment is complex.
Third, the data types are diverse. There are more than 30 kinds of operating systems in the museum, and the data access standard protocols between different software and hardware vary.
Four multi span collaborative complex. The construction of the project needs to cooperate with the venue builder, operator, urban brain, government ministries and other relevant units.
The digital twin smart venue project puts forward targeted solutions in the following four aspects:
1、 Create 3D venue portraits and display multi-dimensional data Kanban
The venue visual display combines multimedia technology, network technology and three-dimensional technology to realize the virtualization of data processing. Through the omni-directional monitoring of objects, a reality based 3D virtual reality effect is built to make the data display more intuitive and easy to understand. The UE4 3D rendering engine is used to make the model have realistic visual rendering effect, with a variety of built-in simulation calculation models. It natively supports data-driven, multi-level detail display optimization and other features, and can support the rapid construction of 3D visualization scene. Based on the best performance of 3D virtual reality, model the buildings, facilities, roads and other related scenes of the venue, so as to achieve a 1:1 scene restoration effect between the model and the real venue. Make the overall perspective of the venue more intuitive, and make the complex venue scenes easy to express, understand and spread. The 360 ° rotation of the scene is realized by zooming in, zooming out, rising, falling, looking down, looking up and rotating the model.
Secondly, through the big screen interface of easy to know wechat easyv digital twin | Smart City Park factory water conservancy double carbon | three-dimensional map data visualization, multi-dimensional signage of venue personnel, vehicles, equipment, operation topics, events and other related business data is designed on both sides of the page, and data analysis results are presented through charts, curves, disconnection charts, bar charts, pie charts and other different styles.

2、 Support multi scene data sensing through IOT spatial mapping
Through the IOT access platform, access management is carried out for dozens of venue equipment and facilities, such as venue monitoring, fire control, record gate, access control, epidemic prevention, etc. the number of access devices reaches tens of thousands, the multi-source and complex equipment data is collected and processed, and the access specifications and guidance for multi scene and multi equipment are provided. By synchronously mapping the collected data on the cockpit page of twin venues, we can intuitively understand the distribution, quantity and operation of venue equipment; Through the three-dimensional space, the spatial location of all IOT devices can be located in real time, and remote device control can be achieved through the digital twin system, including equipment startup, shutdown, mode adjustment, access to operation and maintenance management data, reading the corresponding historical maintenance record information and maintenance plan of each IOT device.
Carry out all-weather and multi category data collection and dynamic information management and control for the equipment connecting the venue equipment to the twin platform. Through the pedestrian and vehicle equipment system, the integrated management of pedestrian flow, parking, ticket check-in and admission can be realized, the flow analysis and display of vehicle data, traffic data and ticket check-in data can be carried out, and the monitoring and management of equipment used in the competition, including event display equipment, game sound reinforcement equipment, game lighting equipment, mechanical hanging equipment, competition information equipment, flag raising control equipment Monitoring and management of operation status of fare collection equipment and other relevant subsystems. Intuitively understand the equipment distribution, quantity and operation through the overall management of the whole field management equipment; Remote equipment management and control, including the opening and closing of equipment and the adjustment of mode, truly realizes the "one screen unified management" of venue equipment.

3、 "One picture" of command linkage, and the event process is fully closed-loop
Digital twin venues combine geographic information system and global positioning system to establish a "one map" of emergency command suitable for venues. Conduct real-time alarm for events occurring in the venue through the cockpit page. Based on the mapping of the event location in the 3D model, display the early warning location and early warning logo in the 3D model, click the logo, track the visual angle to the specific location, and display the information and content of early warning events; Display the event processing status for related alert events. Based on the 3D model, the warning sign disappears after the event processing is completed, and the warning sign can be cancelled manually.
Through the digital transfer of time and space, buildings, equipment, personnel and events, the early warning, disposal, scheduling and tracking of emergency events are realized on the twin platform, forming a closed loop of event processing. Meet the business needs of operation and dispatching command. The digital twin smart venue has the function of multimedia information comprehensive processing, which realizes the high integration and efficient integration of resource scheduling, monitoring information, event alarm and equipment process management, so that all kinds of information can be accurately displayed and highly shared, thus greatly improving the efficiency and quality of management.
Support the alarm information of different levels for emergencies such as fire fighting and equipment and facilities failure in the venue. The alarm level is divided into yellow alarm and red alarm. Yellow alarm is defined as primary alarm. It refers to the yellow alarm for the value of venue equipment or events that reach the preset alarm threshold. It reminds venue managers that they need to coordinate resources in advance to prevent the occurrence of alarm events. The event is controlled in a closed loop before it occurs, so as to achieve prevention first and accurate prediction. Red alarm is defined as the event alarm that reaches or exceeds the alarm threshold.
