Several intelligent buildings that extend intelligent building technology into an area are managed in an integrated manner and then connected together hierarchically for unified management. Such an area is called an intelligent community. That is, a centralized control and modular structure design approach is adopted. The management of all subsystems is centralized in the integrated control center. The managers of the integrated control center can inquire and confirm the safety status and three-table status of households within the community. Smart community is another hot trend after intelligent buildings.
Current status of smart communities The basic configuration of the current smart residential community application system mainly includes the following aspects:
â— Information and Communication System: Provides voice communication, video broadcasting, and broadband information services.
â— Security System:
a) The perimeter of the cell is alarmed, and infrared, microwave and other devices are set up. The center can display the alarm road sections and alarm time.
b) camera surveillance, set up a corresponding detector or camera at the key location of the cell, monitor relevant information and transmit images and record and store. Video intercom.
c) The residential houses have functions such as gas leak alarm, door magnetism, infrared, glass breakage, leak detection, and emergency help.
d) Set up a cable broadcasting system in outdoor public places in the community.
e) Management and billing of incoming and outgoing vehicles through smart cards or other forms.
â— Construction equipment monitoring system:
a) The monitoring of the water supply and drainage monitoring system shows the relevant operating status.
b) The fault condition of the elevator's working status and the location of the floor are monitored.
c) Monitoring of lighting equipment.
â—Property Management System:
a) Configure practical computer property management software to realize the computerization of residential property management and establish a community management information system.
b) Realize remote meter reading function.
c) Each system implements information connectivity and unified management.
Of course, in the actual construction process, other functions can be added according to the needs of the market.
However, there are still many problems in the construction of smart communities. In order to realize centralized monitoring, the general community sets up a central station with a computer as the core in the central control room, and the substation takes the microprocessor as the core to form a distributed distributed computer system. The substation microprocessors are mainly MCUs such as 486 and 586, and they have imported dcs modules. Either the product is not advanced or the cost is high. This makes the intelligent community management system less stable, reliable, and advanced. At the same time, because the intelligent community project construction is carried out in phases, this also makes the scalability of the system capacity not strong.
There are also some intelligent community control systems divided by function. Each subsystem is vertically divided and cannot share information, and equipment is repeatedly invested.
The solution to these problems can be considered from the following perspectives:
Taking into account the advanced nature of the equipment and technology, smart community system uses lonworks bus technology, so that the entire community network to achieve advanced.
The lonworks control network includes smart modules that are connected by one or more communication channels, ie, smart nodes, and the nodes communicate via the lontalk protocol. Intelligent modules can be programmed to send information and respond to external commands. Because the intelligent module has the characteristics of low cost and good compatibility, taking into account the actual conditions of the intelligent community project construction in phases, it is very beneficial to the scalability of system expansion.
The intelligent residential control system of the current LNS architecture is entirely because LNS multi-server technology can bring many benefits to network users: greatly reducing development time and costs; simple system integration; unlimited access to data, etc. This is why the demo system described in this article uses the LNS architecture.
The future of smart communities The development of smart communities in the future has two main aspects:
The first is "people-oriented" thinking. In the future, community construction will gradually deepen into the construction of an intelligent home. For example, the residents of the community can realize "e-currency" transactions or online shopping, medical diagnosis on the Internet, visit virtual museums and libraries, and on-demand vod home theaters; even community residents or intelligent community management and control centers can apply to residents of their communities. Air-conditioning equipment and home appliances are remotely controlled, allowing you to check and confirm the security conditions in your home, anywhere, anytime. In short, the design of the smart community in the future will adhere to the idea of ​​humanized system design, provide residents with warm, comfortable, convenient and economical services to the utmost, and always think about the residents.
Second, the "energy saving" idea. Environmental protection is an important theme in the 21st century, so the future construction of the community will take more consideration of environmental issues. Mainly reflected in the residential residential energy supply, in line with the principle of energy conservation, so that community facilities in the service part of the same time, so that residential residents, community facilities, community environment, a high degree of unity, harmony and integration.
There are more than 400 households in Ruiyuan Township. In order to realize the functions of calling, intercom, surveillance, unlock (fingerprint and key), networking, and security alarm, the entire community is equipped with a management center (sd-980m2), and the management center is interconnected with the management computer.

Dye intermediates mainly benzene intermediates, toluene intermediates, naphthalene intermediates and anthraquinone intermediates four categories, in addition, there are some heterocyclic intermediates. The main intermediates in the production of the reaction process are nitration, sulfonation, halogenation, reduction, amination, hydrolysis, oxidation, condensation and so on. Synthesis of a complex structure of the intermediate often go through many unit processes, sometimes using different basic raw materials and different synthetic routes. For example, the production of p-nitroaniline, the initial nitration with benzene, reduced aniline, re-acetylation, nitration, hydrolysis of the synthetic route, this method of long production process, high cost. Has now switched to benzene chlorination, nitration, separation of nitrochlorobenzene, and then high pressure ammonia solution synthesis route. For the manufacture of dyes, pesticides or Pharmaceutical Intermediates, usually complex structure, often supporting the final product and production, smaller production, production and more use of intermittent operation. Some of the most widely used intermediates, such as nitrobenzene, aniline, chlorobenzene, phenol, etc., are usually produced in a large, integrated chemical plant with large production volumes and continuous operation in production.
