Thanks to the application of Internet of Things technology in the intelligent park, the required functions can be realized more simply, providing an effective supplement to the traditional park intelligence, and a modern new type of park that can adapt to the development needs of the information society.
II. Drawbacks of traditional parks
There are many problems with traditional park systems:
- High energy costs: enterprises lack effective energy monitoring and management tools, and energy waste is huge.
- Low safety protection: lack of backward means of fire prevention and disaster prevention, lack of efficient and precise personnel management system.
- Information exchange occlusion: lack of intelligent linkage between people and people, people and things, and things and things, and lack of effective state collection channels.
- Inadequate supervision and maintenance: decentralized staff, lack of human interaction with the park, and lack of effective feedback channels.
III. Program objectives
It seems that traditional parks generally lack effective technical means for centralized management. The "Smart Park" planned by World Power Technology is to solve the problems of traditional parks and realize the smart management of parks.
◍ The smart park mainly fulfills the following functions:
- Reducing energy consumption and promoting resource efficiency
- Intelligent control of regional resources such as parking lots, public areas, and office areas improves resource utilization efficiency and reduces energy consumption and emissions.
- Optimizing the working and living environment
- Create a comfortable working and living environment by monitoring and regulating fire, security and air quality in the building through intelligent means.
- Ensure safe and reliable operations
- Through the division of authority, monitoring of key areas, fire prevention and disaster prevention and the linkage of access control and security systems, it provides an important guarantee for the safety of people, property and data in the park.
- Integrated management cloud platform linkage
- Remote panoramic digital GIS display of all equipment monitoring status, cleaning and use status within the park, all-round fine analysis and statistics of basic information of public toilets to realize digital and intelligent management of traditional toilets and enhance the city image.
IV. Design principles
During the design process of this intelligent transformation, the following principles were always followed:
- The principle of maturity and practicality: the equipment and technology used are mainstream, mature products, which occupy a large user market in the corresponding application areas, and satisfy the user's business management as the first element for consideration.
- Standardization and modularization: system design and equipment configuration are carried out in strict accordance with the relevant national and regional standards, and the subsystems are structured and standardized according to the requirements of the overall structure of the system, comprehensively reflecting the advanced technology of today's world.
- Easy management principle: through the advanced system management platform, realize the advanced distributed management. Make the whole intelligent system management and control become more "precise" and "simple", show "humanized" design, improve the efficiency of management personnel.
- Economy principle: the higher performance-price ratio of the equipment to build intelligent system transformation, so that the output of the capital input ratio to reach the maximum value. Can be lower cost, less personnel investment to maintain system operation, providing high performance and high efficiency.
V. Smart Park Transformation Program
Based on years, precipitated terminal product ecology, as well as edge computing gateway technology, the whole smart park solution adopts the Internet of Things, big data, cloud computing, sensors and other technologies, so that the traditional park has the ability to instantly perceive, accurately judge and accurately execute, and realize the fine management of the park, which is in the industry's leading position.
The terminal has independent communication capability, and the failure of a single device does not affect the operation of the whole system. IoT devices are rich in variety, and the functional modules are flexible in combination, avoiding excessive construction on the basis of meeting the demand. The platform has a high degree of openness and can be docked with various third-party systems through standardized interfaces. With the massive access capability of the platform and gateway, it is convenient for later expansion.
Based on Cat1, LoRa, Zigbee short-distance wireless and other communication methods, it can effectively reduce the construction wiring, especially suitable for the intelligent transformation of existing buildings.
