I. The concept of intelligent community The concept of intelligent community is derived from the combination of the characteristics of intelligent buildings, smart houses and domestic communities. In China, the concept of smart homes has been promoted relatively late, but its development speed is very fast. Due to the particularity of the domestic housing industry, smart communities have replaced the concept of smart homes, and some homes with certain intellectual functions have been established nationwide. Community.
With the advancement of intelligent technology from the building to the community, we will enter into millions of households, and the connotation of intelligent communities will also continue to be enriched and developed. So what kind of standard or model can we call a smart community? Recently, the Ministry of Construction’s Office of Housing Industrialization has proposed the basic concept of intelligentization of residential communities, namely: “The intelligentization of residential communities is the use of 4C (ie, computers, communications and networks, self-control, and IC card) technologies through effective transmission networks. Integrate multiple information service and management, property management and security, and residential intelligent systems to provide high-tech and intelligent means for the service and management of residential communities, with a view to achieving fast and efficient premium services and management, and providing a safe and comfortable home environment ."
Second, the function of the intelligent community Intelligent system intelligent function settings, generally should be based on different market positioning (is the mid-range or high-end?) And different. Including security monitoring, access control management, computer networks, home security alarms, three forms of households, modern communications, cable television, equipment monitoring, community card, computer property management and other intelligent subsystems, as well as the community electronic screen, background music, E-commerce, information services, VCD on demand, etc. Among them, intelligent community security and communications, the network is the first consideration of the intelligent community. Most of the intelligent buildings are familiar, but the intelligence of the residential area is not a simple function copy of an intelligent building, which cannot fully meet the requirements. The residence has its own special aspects. It needs to integrate more and more equipment and systems in the house so that it can have intelligent functions so as to achieve and create a comfortable and healthy environment, with a high degree of safety and good Communication functions, including transmission of voice, text, and images.
The most prominent feature of an intelligent community is the information service. Its service functions include convenient management, efficient monitoring, and advanced communication methods. Information services are prominently embodied on computer networks, which imposes requirements on the hardware construction of community networks. The current bandwidth problem is the bottleneck that restricts the development of the network. The gradual application of broadband technology solves the problem. According to the prediction of the relevant authorities, broadband networks will have a big development in the next few years, at which time the development of the network will truly enter the mass families. The way to implement functions of smart products is generally to establish intelligent control networks in the community and use this network to implement home intelligent controllers.
Smart communities are families and each family forms smart homes. Smart homes are various information-related communication devices, home appliances, and home security devices in the home. They are connected to smart control networks through home buses for centralized or off-site monitoring, control, and family affairs management. These are maintained. Harmony and coordination between family facilities and the residential environment. These functions are all achieved through the home controller. The home controller is realized through the intelligent controller. The home controller provides various service functions through the intelligent control total system and can connect with the outside world outside the house. So the home controller is not only the "brain" of the smart house, but also the "neuron" of the community intelligent management network system.
Third, the development of intelligent community Intelligent community as an advanced new things, has been supported by all aspects, making it possible to rapid development. With the expansion and extension of the connotation of smart communities, the smart community market has been driven by the promotion of integrators, developers, manufacturers, and various media, under the strong support of the Ministry of Construction, the Housing Industry Promotion Center and other government departments. From disorder to specification, from point to spread.
At present, real estate developers everywhere are more interested in the construction of smart communities and have profound market factors. The booming market for intelligent residential and smart community construction is a kind of shopping mall, and it will surely be recognized by commercial establishments. The correct guidance of the government will be conducive to the standardization and scientific construction of intelligent communities. People from all walks of life have joined the ranks of promoting the intelligent development of the community. System integrators are at the forefront. They come up with the experience and technology in the intelligent building project, put forward a variety of community intelligence solutions, and put a lot of effort into the development of residential products. As a pioneer of domestic intelligent buildings, Deda naturally follows the lead. After the concept of intelligent community was first introduced in China, the IDMS jujube 2000 intelligent community comprehensive management network system was subsequently launched to provide a comprehensive community intelligence solution. Real estate developers are passive in the early days of smart buildings. Everyone is waiting and seeing at the beginning stage of intelligent communities. After understanding the benefits of community intelligence, real estate companies, community residents and integrated companies, and news media agencies give real estate to real estate developers. Developers have exerted a great influence. In this case, developers have to try to do a few simple intelligent systems, such as video intercom systems, parking management systems, etc., but did not expect it to bring With considerable economic and social benefits, they naturally took the lead in the intelligent community.
Fourth, the prospect of building an intelligent community At present, China's residential development is in a period of high-speed, a large number of residential construction, is still an upward trend, and this upward trend continues for 30 to 40 years. Residential demand will continue to grow. This need mainly comes from:
1. The housing demand caused by the increase in population growth and urbanization.
2. Improve the housing demand caused by living conditions.
3. The rapid development of the national economy will further stimulate housing construction.
4. The improvement of investment and financing policies has provided superior conditions for the development of the housing industry.
Here are two sets of authoritative estimates of the urban residential construction market for the next decade:
The first group: “By 2010, China’s housing construction will have an area of ​​8 billion square meters. In the near future, we will focus on the construction of low-end housing. When the time comes, the number of households with housing difficulties and the availability of housing will not exceed 5%.†This is the Standing Committee of the National People’s Congress. Cheng Siwei, vice chairman and director of the Management Science Department of the National Natural Science Foundation, made an update on China's future residential construction at the 5th Asian Real Estate Society's annual meeting. His projections are based on the fact that China’s housing construction rate will remain at an annual growth rate of 9.4% in the next decade; in 1997, China’s urban population totaled 368.89 million, which is calculated as 3.19 households per household, with about 120 million households. Urbanization rate 30.1%. If we had a population of 1.4 billion by 2010, an urbanization rate of 40%, and an estimated per capita housing area of ​​150,000 square meters, we would need an area of ​​8.4 billion square meters of housing, after deducting the actual housing area of ​​3.6 billion square meters at the end of 1997, and Consider the average annual update rate of 2.5%. It is necessary to build 8 billion square meters of housing area between 1998 and 2010.
The second group: reform and opening up, residential construction has developed rapidly, and residential demand is very strong.
Based on the above two sets of figures, we can estimate the intelligent community and target market space:
From the statistics above, it can be seen that from 2001 to 2010, the average annual residential building area was 335 million square meters. Calculated according to 100 square meters of housing area per building, then 3.35 million sets of urban residential buildings will be built each year. The Ministry of Construction's Housing Industry Office Document [1999] No. 04 has a standard for community intelligence, that is, the minimum standard for the intelligentization of residential communities is estimated at 4,000 yuan/household. According to this intelligent standard, the proportion of smart residential districts at the same time is conservatively estimated to be 10% to 30%, then the average annual new smart home will be 335,000 to 1.050 million units in 10 years, and 5,000 yuan in accordance with the average standard of intelligence. According to the calculation of households, the average market size of smart communities will reach 16.75-50.25 billion yuan per year in the future. With the continuous deepening of the housing system reform and people's increasing demand for residential environment, the value will be greatly increased.
The above two sets of data are undoubtedly good news for companies that are dedicated to building intelligent communities. The adjustment of the market and the tilt of the government's policies have made the smart residential market promising.
V. Intelligent Community Market From the perspective of the previous analysis, the smart community market is under a variety of technological applications, a number of residential development companies, and a variety of residential products under complicated conditions. According to several years of intelligent building projects With practical experience and experience in the development of smart community products, we tentatively divide the current market for smart residential products, roughly subdividing the situation in the three worlds.
1. Geographical division At present, residential product development companies are mainly concentrated in a few cities and regions. From a development point of view, the most competitive companies are concentrated in Beijing, Shanghai and Shenzhen. Form a tripartite pattern.
2. Divide from the technical route From the perspective of the technical route, it mainly includes LONWORKS fieldbus technology, BACNET bus technology, RS485 bus technology, HFC-coaxial fiber hybrid network technology, IP technology, power line carrier transmission, wireless technology, and so on.
According to the experience of our engineering practice and the trend of the development of intelligent technologies, intelligent building system integration is a sign of the development of intelligent buildings. System integration marks that buildings have started from single-function and single-system to multi-function, multi-system and comprehensive. Building direction. The fieldbus technology represented by LONWORKS technology will surely dominate the trend of a unified platform.
The information service has become one of the most important service modes of the smart community. The construction of the network is very important. How to unify the local area network with the control network. What is more important is to realize that all households in the community can monitor everything in the home on the Internet, obviously using BACNET. Bus technology (management bus technology), IP technology can solve this problem, this technology undoubtedly occupy a country. Lucent has already launched WAVELAN technology, as well as the recent blue technology (BLUETOOLTH). All indications are that wireless technology will surely occupy the last corner in the future. Therefore, on-site general route technology, IP technology and wireless technology will become the pillars of intelligent community technology.
3. The goal of dividing the intelligent residential and smart community building from the realized functions is to provide people with: “convenient and quick information communication, safe and comfortable living environment, and efficient and convenient property managementâ€. Although the requirements for intelligent sub-systems in intelligent houses in different regions and different grades may be somewhat different, because it is a commodity, there is a commonality and there is a market standard. The Ministry of Construction has made clear provisions in the "Outline of the National Intelligent Technology Demonstration Project for Residential Districts" and the intelligent community: "popular," "advanced," and "leading." This summed up, the content of the functional services provided by the community can be divided into three categories: living security, convenient life, and well-informed. In short, the connotation of intelligent communities in these years has been continuously enriched and improved, and some intelligent communities with Chinese characteristics have been established in the country.
With the advancement of intelligent technology from the building to the community, we will enter into millions of households, and the connotation of intelligent communities will also continue to be enriched and developed. So what kind of standard or model can we call a smart community?
