摘　　要：针对基于STCI2LESA16系列单片机系统、Protel 2004工具设计系统受到采样干扰数据影响,而导致净化效果差的问题,提出基于AVR单片机的室内空气净化装置控制系统设计。采用AVR单片机系列的ATmega128单片机,设计系统总体结构。利用紫外光灯管驱动控制电路,采用LHi878热释红外传感器,经过外围元件和LM358两级放大电路放大信号后,将结果显示在VFD真空荧光显示器上。利用算术平均算法去除干扰数据,由此设计净化流程。通过实验对比结果可知,该系统净化效果好,能够满足一般家庭空气净化需求。In view of the fact that the design system based on the STCI2LESA16 series single chip microcomputer(SCM)system and the Protel 2004 tool is affected by sampling interference data,which result in poor purification effect,a design of indoor air purification device control system based on AVR(automatic voltage regulator)SCM is proposed.The ATmega128 SCM of the AVR SCM series is adopted for the design of the overall structure of the system.The control circuit of the ultraviolet lamp drive and the LHi878 pyroelectric infrared sensor are adopted.The signals are amplified by the peripheral components and LM358 two⁃stage amplifier circuit,and then the results are displayed on vacuum fluorescent display(VFD).The arithmetic mean algorithm is used to remove the interference data and design the purification process thereby.It can be known from the results of the experimental comparison that the system has a good purification effect and can meet the general needs of household air purification.
