Design Of Air-Conditioning Controller In Intelligent Buildings Based On ARM7

Along with the development and combination of information industry, control technology and Architecture, and with people expecting to improve the quality of life, Intelligent Building (IB) is advancing to ever-higher levels. As the core of management system in the building—Building Automation System(BAS) controls and manages automatically the mechanism and electricity facility in building, such as chiller heat-exchanger, air-conditioning, illuminator and elevator. And the run of facility is optimized, energy and labor is saved, efficiency is improved. The monitor system of air-conditioning, which is an important part of BAS, is becoming more important.The air-conditioning in IB designed in this paper, can continuously control the temperature and humidity of the building, and keep it within suitable sensation in spring, summer, autumn and winter.In this paper, the LPC2387 made by NXP Corporation is applied as kernel chip, which externs power module, man-machine interface module, data storage module, bus interface module and communication debugging interface. The power module gives power to LPC2387 and other chips to make them working normally. The main function of the man-machine interface module is transmitting the acquired data to display, so the result can be intuitively saw by staff. The function of data storage module is memorizing the collected data, and making it inspection convenient. The main application of the bus interface module is transmitting the measured data to LPC2387 and transmitting the control single to actuators. Communication debugging interface is used to download programme.The process of system debug indicates that the hardware of air-conditioning control system has achieved prospective target. The mini-system of LPC2387 is running normally, and can collect and display temperature and humidity.
