】 【Weak current College on building automatic control system and interaction design.

<br> <br> In intelligent building design, the architecture of the intelligent design of the system is set, there were several practices. One way is that it should be integrated in various subsystems, is what we usually call it systems integration 3A, .such practices, the momentum in previous years. When it comes to intelligent building, will make such integration, or else that does not refer to it as intelligent building, after nearly two years of extensive engineering practice in this area began to cool down a bit .. Another way is building within the subsystem are relatively independent, each subsystem in dealing with the work of the system itself, and other various subsystems without physical contact on the system. This approach, each subsystem work status is good or bad, is the subsystem's .own situation to decide, influences from other subsystems. There is also a way, it is selectively to certain usually work between associated subsystems, produces a linkage relationship, may also wish to call the relevant subsystem little integration. <br> <br> In .intelligent building system integration that have different practices, this is a normal phenomenon. Throughout the development of intelligent buildings in China, really in the construction industry, and extensive planning and design are also only a few years time, that is, from the early 1990s ., the development of China's capital, in the peak period of the intelligent system will gradually be majority owner, real estate developers and designers understanding, awareness and acceptance of, and begin to proceed with the design and implementation. But as intelligent building some subsystems, .as early as the 1980s began to carry out the design. Since the beginning of 96 held in Shanghai of China's first intelligent building seminars, at the industry's only truly systematic and targeted in this respect a great deal of work. With the intelligent building design, .research, began to question the system of integration, many contractors at this time, to the company's business development, have begun to expand its business scope, played under the banner of the system integrator. <br> <br> However, at the international .level, the development of intelligent buildings, and like we did speculation of Dubrovnik, which is in line with a pragmatic attitude, the what system, by those who have the expertise of the contractor. Need to integrate and to what extent, are from the .practical application of the terms, where there is a liaison between systems, by increasing development of the Internet. To achieve the necessary linkages between information resources can be shared. <br> <br> About building automation system, "civil construction electrical design specifications ."JGJ/T16-92 in its reference to more explicitly, its features, almost includes quite a bit of context, but its main purpose is: <br> <br> 1. ensure that building (Group) in comfortable environment; <br .> <br> 2. improve the building itself, as well as personnel and equipment of the overall level of safety and disaster prevention capacity; <br> <br> 3. adoption of the best control save consumption; <br> <br> .4. the provision of reliable, affordable energy supply of the best programmes for energy saving and management; <br> <br> 5. make the device running efficiently, reduce the labor intensity of workers; <br> <br> 6. continuous .and timely provision of relevant information on the operation of the equipment, centralized collection, collation, as device management decision making, implementation of automation equipment maintenance work. <br> <br> Pursuant to the above application functionality, BA systems should be divided into .two subsystems, they are: <br> <br> 1. fire and security subsystem, including: <br> <br> A. fire alarm and fire control system; <br> <br> B. personnel access monitoring system; < .br> <br> C. Security patrol system; <br> <br> D. burglar alarm systems; <br> <br> E. other need to implement security monitoring systems (such as earthquake monitoring and alerting, gas leak alarm etc ..). <br> <br> 2. equipment management and control subsystem consists of: <br> <br> A. heating, ventilation and air conditioning (HVAC) systems; <br> <br> B. water (with cold .water, hot water, drinking water) and drainage systems; <br> <br> C. distribution and self-powered system; <br> <br> D. power supply and lighting control; <br> <br> E. other .all necessary monitoring of the system (such as an elevator, broadcasting, cable television, etc.). <br> <br> From a technical point of view, these two types of classification, with the subsystem hardware resource sharing good, convenient for .the overall management and maintenance, can be integrated in the normal and abnormal situations device control programmes, so as to achieve comprehensive centralized monitoring. <br> <br> This system of formation, and international practices are similar. But China's fire management system requirements .for fire alarm system should be a separate system. But as technology development, gradually in some places allow automatic fire alarm system to signal the building automation system. <br> <br> This approach, we were in Beijing, a key project design, .take the building automation system, closed circuit monitoring system, alarm system, access control system for organic integration, or call the linkage to meet the needs of the actual operation management. <br> <br> In this project, the linkage between the subsystems ., an event can be raised as an example, look at the relationship between it and the action. For example CCTV security system and anti-theft alarm system, during the day due to monitor regional personnel walking up and down, closed circuit monitoring system is .operational <br> In addition, for building set of access control systems, and fire alarm system, linkage, when the fire alarm and confirmed that the relevant fire channel access will also be able to bypass to enable staff to successfully carry out evacuation, guarantees .the safety of the building. Through the practice of project design, the design sense, to achieve various subsystems to organic and linkage, the first requirement of each subsystem in the communication protocols should be consistent, avoidingFree in the integration process appear to integration, or .need some additional facilities to integration, to the owners of undue burden. The consistency of information resources, not only on the contractor's request, but the smart building system of the whole process. Because the market has yet to achieve a unified standard, all of .the system is not entirely by a contractor to provide, and each manufacturer's product are not identical, they are also different communication protocols. On the current market situation, when determining the products so several circumstances: <br> <br> A bid by system .integrators, unified by the successful party to consider various subsystems product manufacturers. This approach, easy choice communication protocol consistent product, to better meet the linkage between the relevant subsystem (or integration). That is, BMS system, between the subsystem easier to achieve .shared information resources. <br> <br> The second way is by the owners themselves or determine the various subsystems of the contractors, after the system is responsible for the total package. This practice, owners often one-sided pursuit of a price, .and ignore the system integration issues that must be noted that the system did not achieve the unified communication protocol. Some systems do not have open, because of the deficiencies, to the contracting parties brought difficulties, eventually the owners themselves. In order to be able .to centralize management of BMS, to achieve the shared resources between the various subsystems, and to spend additional funds to compensate. For example, in the design phase, the design officer under engineering requirements and characteristics of reasonable conduct subsystem integration between, in the integration .process, you can require various subsystems of communication protocols should be consistent with the TCP / IP protocol. <br> <br> In view of the intelligent building of existing problems, one is not yet a formal design standards, and also there is no .uniform acceptance criteria, specific to one kind of degree, what standards to acceptance, it is difficult to be on. Thus causing some system is not functioning correctly, which results in some places of investigation in certain proportions. This also is present in the design .and construction of quality problems. For design and construction issues, generally include the following: <br> <br> 1. Designer to understand not deep, the basic design of the unit is not intelligent system, but rather to system operators. While system .contractors as in business negotiations, lower cost, thus deepening in system design, to stop time, lower standard, control point less precision is not reasonable, not meet the requirements, but the system up and running. <br> <br> 3. .construction issues, quality does not meet requirements, the current domestic contractors, because the operating reasons, site builders, only part of the company's employees, mostly temporary or cooperation of construction party, many people's quality is not high, the construction of the barbarian. .<br> <br> 4. the company's internal staff, DMV, could someone responsible works better, but some are not, not everyone has a high level. <br> <br> 5. the company for some benefit, fame and fortune .of the project can be taken seriously, on the other hand you have discount, resulted in some large companies when it comes to making small live. The owners produce mentality of emotion, is what is basis to determine whether the contractors. In short, building .automatic control system of interaction design, we implement an important link in the BMS system. From the design, construction and contractor should be closely coordinated with, and understand the design intent, elaborate construction. The only way to achieve a real sense of system interaction .(or integration), reached the ability to handle emergencies. Only in this way, you can improve the intelligent construction equipment management capacity to meet the desired requirements. <br> <br> <br> <br> <br> <br> .<br> <br> <br>, <br>.
