基于PIC16F877A的车内有害气体检测控制系统设计

A design of the harmful gas detection and control system based on PIC16F877A

在研究车内有害气体成份的基础上,设计了一个基于PIC16F877A的车内有害气体检测控制系统。对该系统的控制方案、电源电路、复位电路、振荡电路、传感器检测电路、车窗控制电路、语音控制电路和相应的控制软件进行了设计。试验表明,该系统能有效检测车内确定的有害气体成份,并能对车内有害气体浓度进行有效调节,可改善车内空气质量。

Based on the study of the composition of the harmful gas in the car,the author designed a harmful gas detection and control system based on PIC887A,which includes the design project,power supply circuits,reset circuits,oscillatory circuits ,sensor detection circuits ,car window control circuits,voice control circuits and corresponding control software. It indicates that the system can detect determinate harmful gas existing in the car and adjust the harmful gas concentration effectively,thus improve in-car air quality.
