1. Digital Twin Park
Digital twins, smart parks, wow! Seems like a difficult concept to understand! Don't worry, it will be clear at a glance after listening to my explanation!
(1) Digital twin
Digital twin is a simulation process that makes full use of physical models, sensor updates, operation history, etc., integrates multi-disciplinary, multi-physical quantities, multi-scale, and multi-probability simulation processes, and completes the mapping in the virtual space to reflect the entire life cycle of the corresponding physical equipment. process.
That is to say, using technology to simulate the real world into a virtual space, the content in the virtual space will change in real time with the real world, so that the real world can be described, monitored, managed, etc. in real time.
(2) Smart Park
A smart park is an improvement of intelligence based on the informatization of the park. It is the frontier of a smart city, an important engine for the development of the digital economy, and the main channel for all kinds of parks to be networked, digitized, and intelligent. Its system structure and development model are the epitome of a smart city within the park.
The vernacular is to use digital technologies such as the Internet of Things, big data, and cloud computing to upgrade park management, service efficiency, and high-quality environment.
(3) Digital Twin Park
Knowing the concept of digital twins and smart parks, then digital twin parks are the application of digital twin technology in parks, which is a manifestation of smart parks, allowing the digital world to interact with physical spaces, thereby improving park management capabilities, production efficiency, and services. efficacy.
2. Reasons for development
(1) Policy-driven
In March 2021, the Central Committee of the Communist Party of China issued the "The 14th Five-Year Plan for National Economic and Social Development of the People's Republic of China and the Outline of Long-term Goals in 2035 (Draft)" to speed up the pace of digital society construction, provide smart and convenient public services, and build smart cities and digital villages to build a new picture of a beautiful digital life.
In January 2022, the State Council issued the "14th Five-Year" Digital Economy Development Plan, proposing to actively explore the joint operation model of platform enterprises and industrial parks, enrich the supply of services such as technology, data, platforms, and supply chains, and enhance the combination of online and offline resources The level of sharing guides various elements to accelerate the accumulation in the park.
As the country continues to introduce policies such as smart cities and smart parks, provinces and cities have also actively responded to the call of the country and issued a number of local policies for smart parks, with the goals basically consistent with the national goals. For example, in the "14th Five-Year Plan for the Transformation and Upgrading of Shanghai Industrial Parks", Shanghai proposed to create a park with sustainable development space, focusing on "digital base, digital operation, digital economy, and digital demonstration" to release the development vitality of the park .
(2) Technical support
Digital twins can be used in smart parks. The underlying logic is the development of productivity, and "technology is the primary productive force", that is, the development of smart technologies such as big data, 5G, cloud computing, and the Internet of Things makes the construction of digital twin parks possible. .
3. Specific application
How does the digital twin empower the smart park? For the convenience of understanding, the following takes the construction of a digital twin system in a smart park as an example to understand the digital twin park in detail!
(1) Project background
Driven by rapid economic development and government policies, the park economy developed rapidly by means of industrial focus. The park economy in various regions shows a trend of expanding coverage areas, increasing concentration of output value, and increasing proportion of GDP. Enterprises in the park are gradually developing into high-tech, new fields and professional industries. In the future trend, the park will be a concentrated R&D center for high-tech industries, an area where high-tech enterprises cluster, and a base for high-tech product incubation and production.
(2) Difficulty analysis
One is the scattered sources of data. The sources of data required in the project are scattered, and the business data are scattered in different business systems, making data collection difficult.
The second is a wide audience. The user groups and user roles for the project construction are relatively complex and diverse. It should not only be used as a park comprehensive capability display for visiting leaders and external people, but also be used as a park property management system. For visitors, the digital value of the park should be highlighted For managers, it is necessary to focus on reflecting the management functions of the park.
Third, the emergency response capacity is insufficient. The scene of the emergency is unclear (such as the location of the incident, the number of personnel, the condition of the facilities, whether there are dangerous goods, etc.), which leads to passive command and dispatch.
(3) Construction ideas
Built five thematic modules of the park overview, equipment management, resource management, vehicle management and smart security, and built a refined model in the park around the theme of the smart park, including the demolition scene of the main building, the surrounding effect scene of the park, and parking lot management Scenarios, equipment control scenarios, resource management scenarios, elevator management scenarios, firefighting scenarios, epidemic prevention scenarios, etc., through the analysis of the above scenarios, can play a supporting role in the security management, risk control and emergency command of the park.
(4) Scenario planning
The smart park is a medium and high-tech industrial park mainly for offices, covering an area of about 73 mu and a building area of about 160,000 square meters. The park is oriented by industries such as information technology, medical health, science and technology finance, new materials and new equipment, research and development economy, and headquarters economy.

1. Equipment management
This module is composed of four views: park equipment statistical analysis, equipment distribution map, park scale analysis, and park industry distribution analysis. The four views are related to each other.
In the equipment management scenario, the key facilities and equipment in the park are managed and controlled, including street lights, access control, cameras, cigarette poles and other IoT sensing devices. At the same time, the digital twin platform can be used to control the switch of street lights and access control in real time, and comprehensively control the park equipment through big data and equipment. . When interacting, users can directly click on the street lights in the park to check the operation status of the street lights, or click on the specific location of the equipment distribution to check the status of the street lights.

3. Vehicle management
This module is composed of four views: parking space analysis, charging pile situation analysis, traffic flow situation map, and vehicle traffic record map. The digital twin 3D visualization scene maps out the comprehensive situation of time and space information, and upgrades the traditional static plane display. It is a dynamic mirror space for real-time perception, dynamic online, and virtual-real interaction.
For example, in the analysis of charging piles, the status of charging piles at different locations is displayed through the four dimensions of charging pile usage rate, device name, device status, and device location. Users can timely repair and repair charging piles according to the status of charging piles. Maintenance greatly reduces the risk of fire after charging pile failure.
