摘 要
目前，国内大部分住宅的室内污染状况堪忧。各种新型建筑材料、装修材料、日用化学品进入住宅成为室内污染源;另外，空调的使用和普及使室内通风率比以前明显下降，造成住宅室内污染的累积，致使室内的空气质量相对恶化。由于上述种种原因，造成我国大部分居住建筑的通风状况相对较差，基本上不能满足我国《民用建筑室内环境污染控制标准》的有关规定。
在自然通风不能满足需要的时候，往往可以通过机械通风方式来改善室内的热环境和空气品质。论文所研究的的室内环境调节系统充分利用室外环境条件，通过对建筑物室内外温度、湿度等的测量、比较、优化，进而控制送风设备、排风设备和窗及窗帘的状态，配合并联动空调的运行，达到智能调节建筑物室内环境的目的，以此改善室内空气品质。
本系统采用层次化、模块化设计。整个系统由数据采集系统、单片机控制系统和计算机监控系统组成。系统以单片机SST89E58RD2为核心，以JWSL-2系列壁挂型温湿度传感器等作为测量元件，通过单片机与传感器相连，采集并存储传感器的测量数据。在单片机系统中，还要实现数据的实时显示、超限语音报警和数据辅助存储功能。单片机作为监控系统的中心，通过RS232/RS485总线与监控计算机通信，将采集到的数据传输给监控计算机。 监控计算机将单片机传输的数据进行记录、存储和处理，供工作人员浏览、记录和进行相关理。

ABSTRACT
At Present，most of the domestic indoor pollution situations are worth anxious. Various new building materials，decoration materials and commodity of chemical enter into indoor environment and become sources of pollution. In addition, the use and popularity of air-conditioning decrease the indoor ventilation obviously，resulting in the accumulation of residential indoor pollution and worse indoor air quality. For all above these reasons, most of our country’s building ventilating situations become relatively bad and cannot satisfy the requirements of our country’s ”Civil construction Indoor environment Contamination control Standard ” concerned basically.
Usually，we improve the indoor hot environment and the air quality through the machine ventilation when the natural ventilation can’t meet the needs. The indoor environment regulating system on which this paper study belongs to the area of technology. It is a full use of the outdoor environmental conditions through the survey、comparison、optimization of building indoor& outside temperature，humidity and so on，and then control ventilation equipments、the window and window curtain and air-condition. By this process，the system can achieve the purpose of regulating building indoor environment intellectually and improve the indoor air quality.
This system uses the hierarchization and modular design，the whole system is composed by the data acquisition system，the MCU control system and the computer supervisory system. The system takes the MCUSST89E58RD2 as core，JWSL-2-wall series of temperature and humidity sensors as a measuring device，capture and store the 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 limited pronunciation and the data supplementary storage function. As the center of computer mo
智能新风nitoring system，MCU communicate with computer through RS232/RS485 system bus and transmit the collected date to monitor computer. The monitor computer do the recording、memory and processing jobs for the data which MCU transmits，and then these data are supplied for the staff to browse，record and related process.
