ABSTRACT At present.most of the domestic indoor pollution situations are wonh anxious.Various new building materials,decoration materials and commodity ofchemical enter into indoor enviroment and become sources of pollution.In addition,the use and popularity of air-conditioning decrease the indoor ventilation rateobviously,resulting in the accumulation of residential indoor pollution and worseindoor air quality.For all above these reasons,most of our country’S building ventilating situations become relatively bad and cannot satisfy the requirements ofOUr country’S”Civil construction Indoor environment Contamination controlStandard”concemed basically. Usually,we improve the indoor hot environment and the air quality through themachine ventilation when the natural ventilation call’t meet the needs.ne indoorenvironment regulating system on which this paper study belongs to the area oftechnology.It is a fhJl use of the outdoor environmental conditions through thesurvey、comparison、optimization of building indoor&outside temperature,humidity,and SO on,and then control ventilation equipments、the window and window curtainand air-condition.By this process,the system Call achieve the purpose of regulatingbuilding indoor environment intellectually and improve the indoor air quality. TIliS system USeS the hierarchization and modular design,the whole system iScomposed by the data acquisition system,the MCU control system and the computersupervisory system.The system takes the MCU SST89E58RD2 as COre.JWSL-2.wallSeries of temperature and humidity sensors as a measuring device,capture and storethe sensor data through the connection between MCU and sensors.In MCU system,we have to realize the data real time display、warning when beyond the limitedpronunciation and the data supplementary storage function.As the center of computermonitoring system,MCU communicate with computer through RS232/R$485 system bus and transmit the collected date to monitor computer.1rtle monitor computer do therecording、memory and processing jobs for the data which MCU transmits,and thenthese data are supplied for the staff to browse 编号: 时间:x月x曰 书山有路勤为径,学海无涯苦作舟 页码:
