"Smart city" refers to urban informatization in a broad sense. That is, through the construction of broadband multimedia information network, geographic information system and other infrastructure platforms, the integration of urban information resources, the establishment of e-government, e-commerce, labor and social insurance and other information communities, and gradually realize the informationization of urban national economy and society.
Through the integration of information technology and various resources, smart parks can fully reduce the operating costs of enterprises, improve work efficiency, strengthen the innovation, service and management capabilities of various parks, and create a set of super soft power for the parks. The focus of the smart park is "wisdom": on the one hand, IT comprehensively applies various IT network technologies outside the real park environment, and strengthens the interactive communication and management capabilities within the park through online virtual parks, so as to improve the visibility of the park in a wider scope. On the other hand, it pays more attention to improving the resource integration ability of the park management committee, government, park enterprises and other aspects, integrating and upgrading the professional resources of all parties in the park, and building a strong brand of the science park as a whole.
From the technical understanding: Smart Park combines the Internet of Things, cloud computing and other new generation information technologies to comprehensively perceive and integrate the running state of the city, build the information foundation of the future city, and strongly support the development of the city.
Understanding from the application: Smart Park is the product of the development of information technology to a certain stage. The changes brought by the smart park are not limited to the concept category, but will bring great and far-reaching changes to the production mode, lifestyle, exchange mode, public service, institutional decision-making, planning management, and people's livelihood.
2 the characteristics of smart parks
Because of "wisdom", the smart park no longer stays at the digital level of the park. A smart park that meets the requirements needs to have four characteristics: "people-oriented, comprehensive perception, endogenous development and intelligent collaboration".
1) People-oriented: taking people's needs as the fundamental starting point, promoting social progress with individuals and taking people's development as the foundation, realizing future-oriented digital integration and making human life in the park better; 2) Comprehensive perception: through the perception technology, the relevant information of people and things is comprehensively perceived and interconnected, forming a ubiquitous source of intelligent information; 3) Endogenous development: the park forms an endogenous driving force for sustainable innovation and development, and all components of the city realize self-adaptation, self-optimization and self-improvement around this endogenous driving force; 4) Intelligent collaboration: Realizing seamless connection and collaborative linkage between ubiquitous information is an important way to realize the intelligentization of the park.
To sum up, the smart park is not only the concept of wireless city and digital city that we advertised at the beginning, but also a new urban form that combines "wisdom" and "wisdom". Therefore, a successful smart park must have the four characteristics of smart park, and fundamentally realize the goal of "integration, service, innovation and collaboration" of smart park.
3 "Smart Park" top-level design
In the traditional park system, parks are established and managed by independent departments. However, with the continuous development of the park, population growth, budget constraints and insufficient utilization of infrastructure, especially the traditional management methods can not fully integrate and interconnect the park from the overall point of view, these problems are causing increasing pressure on park managers. To build a smart park, we must fundamentally change the traditional model and regard the park as a single system composed of multiple interrelated subsystems, rather than an independent system. A perfect intelligent park, just like the tallest creature-human, can sense the changes around and inside, transmit these changes through nerves, make overall decisions after brain processing, and issue instructions to be executed by body organs.
The top-level design of "Smart Park" will determine the planning height and boundary. In the top-level design stage, the framework design includes five parts: the park infrastructure layer, the park intelligent perception platform, the park application support platform, the park information application system, the information security system and the information standard system. Frame design is the starting point of high-level design of infrastructure, platform and application system.
3. 1 infrastructure layer. Infrastructure layer is the hardware basic layer of information construction in the park, including land site network; Mobile communication network; Wireless local area network, including public local area network and local area network in the cell; Communication rooms, including communication hub rooms in commercial areas, dense communication rooms in plots and ground equipment rooms; Land information management center, including communication room, data room, security control room and supporting service facilities.
3.2 Intelligent perception layer. Intelligent perception layer is the data acquisition and automatic control layer of the park, including the environmental monitoring system, intelligent transportation system and energy monitoring system of the park; Environmental monitoring system, intelligent transportation system, energy monitoring system, intelligent exhibition system, intelligent meter reading system, security control system, smart card management system, building automation system, information release system, conference system, cable and satellite TV system, emergency broadcasting system, intelligent microgrid, etc. Intelligent perception layer enables physical entities to have perception ability through widely distributed sensor networks, radio frequency identification (RFID) and embedded systems. This part is similar to the nerve endings and neurons of the human body, and is mainly used to collect all kinds of information in the city and show it to all members of the city. Core elements include sensors, RFID tags and readers, cameras, GPS, mobile terminals, kiosks, multimedia phones, personal computers, electronic billboards and so on.
3.3 Network communication layer. The network communication layer is the data transmission and exchange layer of the park, including the management information network supporting the business circle application system and various intelligent perception system information transmission networks. The broadband ubiquitous network formed by the integration of the Internet of Things and the Internet fully realizes the ubiquitous intelligent interconnection between people, people and things, and things and things, and realizes the connection of anyone, anything, anytime and anywhere. It is a safe and reliable seamless connection. In the "smart park" environment, mobility is becoming more and more important, video is becoming more and more important communication media, and the boundaries of workspace (devices, applications and locations) are becoming more and more blurred. These trends and important changes require the network to connect everything together in order to access the required content and information across various business models, deepen customer relationships, improve work efficiency and flexibility, and improve the quality of life.
3.4 Support platform layer. The supporting platform layer is the supporting layer for centralized storage and application of data in the business district park, and it is the brain of the park. This is a comprehensive, unified and interconnected urban management and service platform, which transmits and processes the information obtained by the information collection and display module, and synchronously coordinates the park management and service operation institutions to realize business interoperability, operation integration and unified command among them. Including portal integration, data integration, application integration and business process integration, external interface, etc. The supporting platforms of smart park include smart park operation management platform and smart park virtual service platform. Among them, the smart park operation management platform realizes the monitoring of urban operation and safety emergency through the Internet of Things, video surveillance, cloud computing and other technical means, enhances the government's precise management ability, and makes urban operation safer and more efficient; By providing a series of application services, such as intelligent business, intelligent business, intelligent conference, intelligent medical care, intelligent education, wireless city and smart home, the virtual service platform of smart park can make the service more convenient, effectively improve the satisfaction of enterprises and residents, and benefit the people from the success of urban development.
