摘要
针对环境的气体浓度监测要求,设计了一种以16位单片机MSP430F449为主控制系统的气体浓度监测及无线传输系统,详细叙述了系统设计原理与软硬件的实现方法。系统通过单片机控制半导体气敏元件检测出气体的浓度值,借助无线通信芯片nRF2401,实现对环境中的气体浓度实时采集、测量、无线传输和上位机通信功能。该系统的显著特点是体积小、携带和测量方便、稳定性强、测量精度高,具有良好的应用前景。
According to monitor requirements about gas density in environment, this paper designed a wireless transmission system and gas density monitor based on 16 unit MSP430F449 that act as a key control system. It introduced the system structure and the designs of hardware and software in detail. This system measured the gas density through the SCM controled semiconductor gas sensors. With the help of nRF2401, it realized the functions of real-time acquisition measurement,wireless transmission and communication on microcomputer. This system has the features of small volume, convenient to tote and measure, strong stability , hign precision and favourable apply foreground.
