摘　　要：主要介绍一种基于AVR单片机实现较大空间空气净化系统的设计，着重从电气方面对该净化系统进行了阐述。通过框图和程序流程图的形式介绍了系统的工作原理、硬件组成和软件的设计思路。详细介绍了空气质量的定性检测方面，对传统固定零点、直线逼近算法进行了改进，设计了一种具有动态零点自校准、曲线拟合的算法，解决了传统算法处理中，在同一环境下，由于传感器的零点不同，检测出来的数据之间误差较大的缺陷。随机抽取的四个空气质量传感器在10平方米的空间内通电，进行算法对比试验。通过实验数据比对，验证了改进算法的有效性。A method based on AVR microcontroller, testing air quality and achieve greater space for air purification systems, focusing on the clean side from the electrical system are described. Through the form of block diagram and flow chart describes the working principle, hardware and software design ideas. Detailed qualitative analysis of air quality, the traditional fixed zero point, linear approximation algorithm is improved, designed a dynamic zero self-calibration, curve fitting algorithm.Algorithm to solve the traditional treatment, in the same environment, different from zero because the sensor to detect the error between the data out of large defects. Randomly selected four air quality sensors in 10 square meters of space power, to conduct comparative test algorithm. Through the experimental data to verify the validity of the improved algorithm.
