摘要 随着我国工业化大力发展，大气污染也越来越严重，全国各地多个地区都发生了雾霾等恶劣天气。伴随室外的空气污染，室内也直接受到严重的影响，如API、PM值也越来越高，同时家具，装修也带来了空气问题。然而室内的环境质量是与我们的身体健康息息相关，因此，空气净化治理的装置研发迫在眉睫。它可以为我们提供室内空气净化的解决方案，把室内的污染空气通过自身净化功能后，得到无污染对人体无害的气体，使我们可以安心健康的环境中快乐生活。目前市场中有大量空气净化的产品，我们将设计一种可以无线智能控制的空气净化仪器，它可以稳定的清洁我们的空气。29279

Air purification Wireless Intelligent Control System hardware development
Abstract：With the vigorous development of China's industrialization, air pollution has become increasingly serious, many regions across the country have taken place in bad weather such as fog and haze. With the outdoor air pollution, indoor been seriously affected directly, such as API, PM value higher and higher, while furniture, decoration also brought air problems. However, the quality of the indoor environment and our health are closely related, and therefore, air purification equipment R & D is imminent. It provides indoor air purification solution for us, the indoor air pollution through the self-purification, to obtain pollution harmless gas, so that we can feel at ease and happy life in a healthy environment. There are currently on the market a lot of air purification products, we will be able to design a wireless intelligent control of air purification equipment, it can be a constant cleaning our air.
Indoor air purification wireless intelligent control system designed in this paper, the system consists of two parts, one is the air quality testing and processing part, the other part is that wireless intelligent control part. Through Wifi technology, combine two parts together, you can effectively achieve air purification wireless intelligent control. Design and development of the device includes hardware design and software development program, in which the design of the hardware circuit, the control system includes a control circuit design, respectively, and the driving circuit, based on the detection of indoor air to control the data sent to the processing and setting design a control circuit, the control circuit then works based on functional requirements and design a system drive circuit of each module. After the software program side, the data processing circuit to complete air quality testing, Wifi signal is received, the signal input control board microcontroller, the calculation process and then sent to an air purifier C brushless DC motor is controlled by voice system, make the PID calculation control motor speed. Function module of the device includes: SCM control, power system function, the initial value setting function, display function, the main motor control functions, PM2.5 sensor data acquisition function, PM2.5 purification device function keys and remote processing functions, sensor data acquisition monitoring system and air alarm function.
