How to build intelligent facilities in government buildings

This paper expounds the objectives and design principles of the intelligent construction of government buildings, enumerates the subsystems of the intelligent construction of government buildings, and describes the design ideas of four subsystems of government buildings: structured wiring, building automation, comprehensive security and e-government, which embodies the design concept of "people-oriented". Key words: government, intelligence, design, service 1. The goal of building an intelligent system for government buildings. The construction of government building intelligent system should reflect some characteristics of modern government and be considered from the following two aspects: providing high-tech service platform for the government to carry out various administrative work; Provide an efficient, reliable and comfortable environment for the operation and management of government buildings. 2. Design principle of intelligent system of government building 1. Principle of combining maturity with advancement: In system design, we emphasize the use of advanced technologies that are mature or have been tested by engineering to meet the present and future needs to the greatest extent. On the premise of meeting the maturity, the technology is advanced appropriately. 2. Principles of standardization and openness: Today's world has entered a mass production society. Using non-standard design or non-standard products may lead to the system being unmaintable or costly to maintain. 3. On-demand construction principle: In the implementation process of many projects, many designers and construction workers blindly pursue high-grade products regardless of the needs of the owners, which leads to the failure of the project or the waste of investment. Therefore, before we design, we must first do a good job in demand analysis. We can neither blindly pursue perfection in order to achieve certain intelligence, nor make unnecessary mistakes without standard guidance. 4. Principle of security and confidentiality: Different from ordinary buildings, government buildings not only have leaders at all levels, but also various command systems and related data, so security and confidentiality requirements are very important. In the design, we must pay attention to the physical partition of local area network and confidential network, make clear the application scope of wireless products, and do a good job in the safety design of key areas. 5. Service principle: Different from ordinary buildings, government buildings should always emphasize the "people-oriented" design idea, and the design ideas of comfort, safety, convenience, efficiency, environmental protection, flexibility and easy maintenance should be reflected in all details. Third, the intelligent construction of government buildings. Each subsystem combines the characteristics of government buildings. Intelligent system mainly includes the following subsystems: 1. Structured cabling system (GCS)? Structured cabling system II. Building Equipment Automation System (BAS)? Building automation system? Comprehensive safety management system: including TV monitoring, burglar alarm, perimeter alarm, access control, patrol, wireless intercom and other systems. ? Parking garage management system? Fire fighting system. Communication network system (CNS)? Computer network system: including confidential network, government private network and government extranet (Internet). ? Voice communication system: including fixed telephone system and mobile communication coverage system (China Mobile, China Unicom, China Telecom PHS, etc.). ).？ Cable TV and satellite receiving system? Background sound and emergency broadcast system 4. Office automation system? E-government system? Multifunctional electronic conference system: including audio, display, simultaneous translation, digital conference, centralized control and other systems. ? Video conference system? Emergency command system? Public information publishing system: including electronic bulletin display system and multimedia information inquiry system. ? All-in-one card system: including data borrowing, access management, consumption management, parking management, etc. Property management system. Intelligent security system? Computer room project? Uninterruptible power supply system? Lightning protection grounding system? Integrated piping system 6. System integration (SI) System integration? Building intelligent integrated management system. As the nerve center of the government building, the structured wiring subsystem of the government building is a platform for transmitting voice, data, images and other information, and is an essential infrastructure for government affairs. We suggest adopting the scheme of "Horizontal Category 6+Trunk Cable" to support computer applications, and adopting the scheme of "Horizontal Category 6+Trunk Cable" to support voice and other applications. From the application of structured wiring system in government buildings, it can be divided into: ordinary telephone network, red telephone network, Internet network, government private network, security network and so on. We suggest using unshielded twisted pair for ordinary telephone network, shielded twisted pair for red telephone network and optical fiber to desktop for security network, which can greatly improve the security and confidentiality of the system. The central computer room (equipment room) of structured wiring system should be designed in the middle floor of the building or the central area of the building complex to save investment and improve system reliability. V. Talking about the building automation subsystem of the government building In the design of the building automation system of the government building, the design goal should be to "create a comfortable environment and save operating costs". In system design and equipment selection, the reliability and expansibility of the system should be emphasized. We require that the bus capacity, software resources and DDC I/O points of the system have a margin of more than 15%. The main monitoring scope of building automatic control system: air conditioning and ventilation system, including air conditioning unit, fresh air unit, air supply/exhaust fan, etc. Air conditioning cold and heat source system, including cooling tower, cooling water pump, chilled water pump, boiler, heat exchanger, hot water pump and other equipment. When the ice storage system is used, the water chiller, cooling tower, cooling pump and freezing pump are provided by the ice storage manufacturer. At this time, only the open protocol of ice storage system is needed to provide communication interface. Water supply and drainage system, including domestic hot water, domestic cold water system, drainage system, fire fighting system and other related equipment. Power transformation and distribution system, including high/low voltage incoming and outgoing lines, transformers, contact cabinets, etc. Lighting system, including public walkways, elevator hall lighting, underground garage lighting, floodlighting, aviation obstacle lights, music fountains, etc. Elevator system, including vertical passenger elevator, vertical fire elevator, etc. Humanized design can be introduced into the building automation system of the government building, such as scheduling the conference center through BMS, and starting and stopping the air conditioning and lighting of the conference room through BAS (for example, turning on 10 minutes in advance) to ensure the comfort of the conference environment; Another example is to measure the ambient temperature and carbon dioxide concentration in conference rooms, archives rooms, central computer rooms and other important places to ensure the comfort of indoor environment. With the formation of the concept of "the government is close to the people and serves the people", it creates an open and relaxed environment for the government building and brings a democratic and leisurely atmosphere to the citizens. However, the security system in this environment has a heavier task and needs more scientific design and advanced technology. The security system of government building includes: TV monitoring, burglar alarm, perimeter prevention, patrol management, access control, wireless intercom, parking lot management and other subsystems. The safety system design of government buildings can be divided into three levels: outer layer, inner layer and key area. In the design of TV monitoring system of government building, high-performance fastball cameras should be installed at the height and entrance of the building to understand the surrounding environment. When citizens petition or gather in and around government buildings, they will provide real-time images for government leaders and safety management departments in time. These images should be transmitted not only to the security center, but also to the emergency command center and related leadership offices through the network. The design of anti-theft alarm system should scientifically set up various defense zones, and realize linkage with TV monitoring system and access control system to realize two-way communication between control and alarm. When obtaining investment permission, you can use some anti-terrorism equipment. In order to improve the overall management ability of the security system, the main security subsystems should be integrated on a software platform, and some auxiliary controls should be set up. The security management system of the government building and the public security department must realize remote linkage, not only transmitting alarm signals in real time, but also transmitting important image signals in real time. 7. Talking about the government building 1 e-government subsystem. E-government development stage: the government releases all kinds of static information (such as regulations, guidelines, contact information, etc.). ) is the primary stage of e-government development. In addition to publishing relevant information on the Internet, the government also provides some forms of services to users, and then e-government enters the stage of interaction between the government and users. At this stage, the government can solicit residents' opinions on a certain topic (such as public projects) at any time as needed, so that residents can participate in the government's public management and decision-making; Users can obtain relevant reports online and declare them online. With the development demand, e-government has entered the stage of online transaction processing, which can realize the whole process of online payment, new enterprise registration procedures, e-procurement and other affairs. After entering the online transaction processing stage, it is necessary to adjust the original government personnel, set up some new departments and posts, and reorganize business processes. At this point, e-government will really mature. 2. E-government design strategy: user-centered, convenience-oriented, and an e-government system without users is lifeless. Pay attention to application integration ability and take application as the soul. E-government system construction and data accumulation need time, which is a never-ending undertaking. Long-term planning should be done. E-government system is a systematic project with a huge user group, which needs to solve both technical and non-technical problems. E-government system should make overall planning, implement step by step, give priority to classification, pay attention to actual effect and avoid repeated construction. E-government system should attach importance to infrastructure construction and promote software and hardware construction at the same time. We should do a good job of "one-stop" portal website, enhance interactive ability and provide more comprehensive services. We should pay attention to the security, openness, standardization, interoperability and agility of the system. Operation and maintenance issues should be considered. 3. E-government system. Conclusion The intelligent system of government buildings includes many aspects, and we think that the "people-oriented" design concept and good service consciousness are the most critical. We have designed four subsystems of government buildings, including structured wiring, building automation, integrated security and e-government, which are some concrete applications of this concept. To build the government building into a real intelligent building, we need to make great efforts in environment, structure, heating and ventilation, power distribution, water supply and other aspects. We hope that the concept of "people-oriented" will permeate all aspects, create more personalized solutions and build more landmark intelligent buildings.
