【正文】 拼一個(gè)春夏秋冬！贏一個(gè)無(wú)悔人生！早安！—————獻(xiàn)給所有努力的人. 學(xué)習(xí)好幫手。不奮斗就是每天都很容易，可一年一年越來(lái)越難。是狼就要練好牙，是羊就要練好腿。s basic functions can be summarized as follows: (1) automatic monitoring and control of various electrical and mechanical equipment, the stop, display or print the current operating state. (2) automatic detection, display, print a variety of electrical and mechanical equipment operating parameters and changes in trends or historical data. (3) According to external conditions, environmental factors, the change automatically adjust the load of equipment, so that is always running in top condition. (4) monitoring and timely processing of all accident emergencies(5) to achieve a variety of electrical and mechanical equipment on building a unified management, coordination and control. (6) Energy management: water, electricity, gas metering and charging, etc., to achieve energy management automation. (7) Equipment Management: including device files, equipment operation and equipment maintenance management reports. 3, the principle of building automation control systemBuilding control system used is based on modern control theory, distributed puter control system, also known as distributed control system (Distributedcontrol systems referred to as DCS). It is characterized by a centralized management decentralized control, that is charged with distribution of equipment in the field office of the microputer control (DDC) to plete device charged with the task of realtime detection and control, centralized control of puter to overe the risks of high lack of centralized control and conventional single instrument in the central control room of the central management puter with CRT display, print output, extensive software management and a strong digital munications capabilities to plete the centralized operation, display, alarm, tasks such as printing and optimal control, avoiding Changgui instrument control is distributed difficulties after the manmachine contact, no unified management shortings, ensure that equipment running in top form.Here are distributed control systems with several concepts. direct digital control system (DDC) direct digital control system (Direct Digital Control referred to as DDC) shown in Figure 2. Computer through the analog input channels (AI) and digital input channels (DI) realtime data collection, and then calculated according to certain rules, and finally the control signals, and through the analog output channels (AO) and the switch output channel (DO ) direct control of the production process. So DDC system is a closed loop control system, a puter in the industrial production of the most popular way of an applicationDDC system control puter to undertake tasks, which required realtime, high reliability and adaptability. Composition of direct digital control systemDirect digital control system consists of the process input channel, process control puter, the process of output channels of three parts. Process input channels from the analog input and digital input of two parts.
