Product Learning: Intelligent City Life System Design _ Intelligent City

At the end of 2008, IBM CEO Palmisano proposed the concept of "intelligent earth", the wisdom of the earth is to embed sensors and equipment to the grid, railways, bridges, tunnels, highways, buildings, water systems, dams, oil and gas pipelines and other objects, and is generally connected to form the so-called "Internet of Things", and then the "Internet of Things" Integrate with the existing Internet to realize the integration of human society and physical system. On this basis, humans can be more sophisticated and dynamic way to manage production and life, so as to achieve "wisdom" state. At the end of 2009, IBM unveiled the concept of IBM's "smart city" and its software solutions. "The City of Wisdom" is an important aspect of IBM's "Smart Earth" strategy. "Intelligent Earth" proposes to improve the ability of real-time information processing and response speed, enhance business elasticity and continuity, and promote the all-round and harmonious development of all social undertakings by smarter methods. And IBM's "Smart city" action is officially the IBM "wisdom of the Earth" from theory to practical reality. 3I features of Intelligent Earth: perceptual (instrumented), interconnected (interconnected) and intelligent (intelligent).

Singapore from the National Computerization plan to the wisdom of the country plan. 1. National computerization Programme (1981-1985); 2. National It Blueprint (1986-1991, the establishment of trade network, legal Network and Media network, etc.); 3. it2000-Intelligent Island Program (1992-1999, the construction of high-speed broadband multimedia network covering the country Singapore one); 4. Information Communication 21 Blueprint (2000-2003); 5. The Interconnection Singapore Program (2003-2006) makes Singapore known as the best IT application country (Global Economic Forum, 2005), the third highest level of E-government (Accenture, 2005), 6. Since 2006, Singapore has launched an important strategic "smart Country 2015 Program", which is expected to enhance Singapore's competitiveness and innovation over the next 10 years, using ubiquitous information and communication technologies to create a smarter country, A globalized city (main objective: to enrich the lives of the people through information communication, strengthen economic competitiveness and creativity through information communication, accelerate the development of the information and communication industry, and improve the competitiveness of the industry. ）

Taiwan to implement the "wisdom of Taiwan" concept, promote the "quality of life" strategy. 1. Implementation of the Information and Communication Development Programme (ICT), 1998, 2. 2002-2007, successfully promoted the "Digital Taiwan Project (E-taiwan)", and successfully achieved the "6 years 6 million broadband home" goal; 3. 2005-2009, successfully promoted the "Mobile Taiwan Project (M-taiwan)", Planning the "mobile Taiwan, unlimited application, leap into the New World" technology vision, so that people at any time, any place can use ICT technology, enjoy the quality of information life; 4. 2009-2016, planning to promote the "wisdom of Taiwan (Intelligent Tiwan)" program, with "ubiquitous computing technology" development and application of the trend, "the development of High-quality Networked Society" as the driving direction, accelerate the construction of high-speed broadband network, and interconnection of various network systems, Coupled with wired and wireless sensor network to achieve all objects can connect the network target, and then build a sound broadband infrastructure and application environment.

Intelligent city is the product of the new generation of information technology change.

Internet of Things: 1. An increasingly interconnected network of devices and facilities that are endowed with a certain intelligence; 2. Through a variety of wireless, wired long-distance or short distance communication networks, or intranet (intranet), or private network (Extranet), or Internet (Internet), etc. In the premise of ensuring information security, realize interconnection and interoperability within the selected range. 3. Provide online monitoring, positioning traceability, automatic alarm, dispatching command, remote control, security protection, remote maintenance, decision support and other management and service functions; 4. The control, operation and management of "material" is based on network, real time University and green environment protection.

1. System Architecture Diagram

The architecture diagram of this system is shown below

· GIS Service Station: It is the core of the whole large system, the source of geographic information sharing.

· Departmental Application management platform: consists of business Web server, public service management end, mobile application end.

· Web application Platform: The platform is a plug-in web platform based on Silverligth and supports two of development.

The internal design structure of GIS service station is as follows:

2. The platform each part function introduction

⑴. Service Registration Management Center: In this distributed geographic Information Service platform, the Service Registration Management Center is responsible for the registration and management of all services, as well as the further authorization and security checks for all services (the data Management Office is responsible for the initial audits). The Service Registration center achieves the agreement management of the service, and realizes the advertisement display of all the services, and provides a universal access interface for the service user groups.

⑵. GIS Server: Service user groups in the Service Registry Management Center to get the service list, according to their own needs directly to the GIS server to form a binding relationship. The GIS server provides the appropriate service according to the service user's request. In this distributed Geographic Information Service platform, the GIS server adopts the ArcGIS Server 9.3.1 version of the OGC specification. After the service definition is completed in the Data management office, most of the functionality that follows is provided by ArcGIS Server based on the service consumer's request parameters.

⑶. Data Management Services: The Data Management Service is responsible for the release and management of services posted from the local computer. It includes the processing of heterogeneous data sources in distributed database servers, the preprocessing of service data to be released, the publication of services, the definition of service capability (OGC specification), the management of the rights of the service to be published, and the preview of views. The difference is that when the data Management Service is published, the service is synchronized with the GIS server files, and the services are registered directly to the Registration Management center. When the data management Office completes the map Service release, the data management office can still control the service, but the management of the service is actually provided by the GIS server and does not depend on the data management office.

⑷. Data source: In the distributed Geographic Information Service platform, the data source can be from the network available space database, can also be from the external network access to use the public network data (using OGC specification, to achieve further sharing of data).

⑸. Service consumer: The overall implementation of this distributed Geographic Information Service platform is based on ArcGIS Server9.3.1, where the service use can be connected with ArcGIS products (such as ArcGIS Desktop desktop products, ArcGIS engine, two development). can also be directly used OGC specification technology for access. In the distributed Geographic Information Service platform, the service can be a variety of types (c/S, mobile, or other Web application server). A Web application server invokes a service on a GIS server, which is equivalent to its client for a GIS server. The Web application server invokes services on the GIS Application server and develops implementation capabilities through operations on these services. These functions can be called by the user through the browser to achieve (b/s application), but also in the phone to make remote calls.
