摘要
介绍了一种采用传感技术、嵌入式技术与无线远程通信技术相结合的水稻田甲烷在线监测系统。该系统以STM32F103VB处理器及甲烷(CH_4)气体传感器DynamentMSHia-HC为核心,集成GPRS无线通信等功能模块,实现对水稻田甲烷气体排放实时在线监测。首先,介绍了系统的总体设计与核心结构,包括系统的硬件结构与软件结构;其次,对系统进行性能验证实验。结果表明:该系统具有良好的稳定性,能够在0~5%量程内对甲烷浓度进行实时在线精确监测,满足水稻田环境下甲烷气体排放速率及单位面积的排放通量的实时监测,具有广阔的应用前景。
This paper introduces a kind of online monitoring system of methane in paddy field, which is based on the combination of sensing technology, embedded technology andwireless remote communication technology. The system takes the STM32F103VB processor and methane (CH4) gas sensor DynamentMSHia-HC as the core, integrating GPRS wireless communication and other functional modules to realize real-time online monitoring of methane emission in paddy rice field. Firstly, the overall design and core structure of the system are introduced, including the hardware and soft-ware structure of the system. Secondly, the performance of the system is verified. The results show that the system has good stability, can accurately monitor methane concentration in the range of 0 -5% in real time. It meets the requirement of the real time monitoring of methane emission rate and per unit area of the emission flux in paddy field, so it has a broad application prospect.
