2. Construction of residential district intelligent system 2.1 The overall goal of residential district intelligence construction The goal of residential district intelligent system construction is to use advanced computer communication technology, control technology and real estate property management technology, and adopt an effective system integration method. Establish a multimedia integrated information exchange system that communicates internal households and households, households and centers, households and external communities in the community, and creates an intelligent community that is safe, comfortable, convenient, energy-efficient, and efficient, and that is capable of sustainable development.
The construction of an intelligent residential community can be summarized as the establishment of two platforms: an information platform and a control management platform; two services are provided: property services and information and information services. The construction of the platform is the basis for realizing the intelligent function of the community, and the service is the functional content of realizing the intelligence of the community.
The information platform is to enable residential and community information sharing and resource sharing in the information and digital world. Therefore, it is necessary to build a community information platform that can meet various modern communication bandwidth and speed requirements, including residential residential telephone systems (including future videophones), cable television systems, and residential computer local area networks in order to provide Resource sharing and information exchange in an information society.
The control management platform is a platform for intelligent closed control and management of residential and residential areas. In any intelligent community, a large number of high-tech products will be used to implement community security, home security, self-control of household appliances, and intelligent residential property services and management. These controls and operations should be carried out on a technologically open operating platform in order to apply as many new high-tech products as possible. But starting from security, it must be closed to the outside world.
Property management services provide high-efficiency property services with high-tech means and products, including providing community public security, home security, community “cardsâ€, various intelligent function management of the community, and comfort property services.
Information information service can be said to be the soul of the "smart community" construction. The information information service is by no means merely providing Internet access, but should include comprehensive provision of services such as: online office, VOD video on demand, telemedicine, distance education, online stock trading, e-commerce, multimedia entertainment, online transactions, video and multimedia conferencing, computer information services ,and many more.
2.2 Ideas for intelligent building of residential areas 1. The decentralized control of the intelligentization of residential quarters is a systematic project that involves a wide range of functions, including many functions, each functional requirement, cost control, reliability, real-time performance, and security. The requirements are different, and the monitoring and service objects of each function are distributed in every household and every public area in the community. Therefore, intelligent construction should be implemented in a "decentralized control" approach. According to different implementation functions, they are divided into different intelligent subsystems. Each subsystem sets corresponding monitoring service controllers at the front end of the system according to the monitoring and service object conditions to perform decentralized control.
2. Hierarchical integration For the integration of various functional intelligent subsystems, it is not simply a simple stacking and synthesis of high-tech products. Intelligent system integration design closely focuses on the themes of “people-oriented, on-demand design, and hierarchical integrationâ€. Based on the overall community planning features and practical needs, it fully understands the connotation and decision of integration from the perspective of technology, economy, operation and service. System integration content.
By adopting a molecular system and hierarchically integrated low-to-high level ideas, meticulously designed and planned to improve the efficiency of monitoring and management of the entire community in order to achieve management data, improve and enhance the quality of the living environment, and serve as a community user. Integrate with investors to bring economic and social value-added benefits.
3, hierarchical management of intelligent community management is not a collection of simple management sub-functions, should be from the perspective of the entire community integrated management and service, integration of all information resources, coordination of community residents, property management personnel, property service staff of the three Relationship between.
Management is specifically divided into two levels:
A. Community level: The community level focuses on the senior management of distribution management, overall monitoring and handling of major accidents, and supervision and management of property management in each block.
B. Block level: front-end property management corresponding to each block.
4. There are many subsystems involved in the intelligent construction of structured cabling, and each subsystem needs network communication. The construction of pipe network cabling directly affects the function level of the entire intelligent system and the quality of service quality, so it is necessary to The entire system of pipe network wiring for a unified planning and design. The use of structured wiring makes the wiring structure of the pipe network clear, simple in construction, and convenient to maintain, and can ensure the scalability and flexibility of various intelligent systems.
