摘 要 随着 该系统主要由主控制单元和输入输出控制单元及外围电路组成，控制单元采用公司的单片机作为系统CPU，对温度、湿度及CO2浓度等环境参数进行监控，并且对风门电机、鼓风机电机等设备实施控制。同时利用模糊控制技术对各种模拟信号进行处理、运算，利用苏州创高电子有限公司生产的专用的汽车液晶显示器显示系统信息。 本系统可以对车内通风、取暖、制冷、加湿等功能进行智能控制，并且可以直观的将车载空调的工作状态及数字信息显现出来。在实际中可以将本系统进行广泛的应用和推广。 空调单片机智能控制空气质量模糊控制 ir-conditioners control system design Abstract With the improvement of people’s living standard, car play an important role in our lives. For the time being, car air conditioning control is at a early stage in China. Most of them are hand-manual control of half automatic control. Hand manual control often results in large discrepancy between actual indoor temperature and setting temperature, and it can not satisfy the need of comfort and energy saving. On the other hand, it can decentralize driver’s attention and reduce safety. It is the tendency to realize the automatic control of car temperature. However high-lever car have been setting automatically air conditioning in the overseas, our country always depend on the import. And we do not have the technology by ourselves to make it. This system has the main control unit and input-output control unit and the external circuit, a control unit Microchips PIC16F877 SCM as a system CPU, the temperature, humidity and CO2 concentration, and other environmental parameters are monitored, and the throttle motor, blower Electrical equipment, such as the implementation of control. At the same time the use of fuzzy control technology on all kinds of analog signal processing, calculation, using a high-Suzhou Electronic Co., Ltd. for the production of liquid crystal display vehicle information display system. This system can on the vehicle ventilation, heating, refrigeration, humidification, and other functions of intelligent control and can direct the air-conditioned buses will be the work of state and digital information emerged. In practice, this system can be widely used and promoted. Keywords Air conditioner in automobile Single chip microcomputer Intelligent co
