一种光纤甲烷检测仪智能前端系统的实现方案

Intelligent Front-end System of Optical Fiber CH_4 Detector

在已有文献研究的基础上,基于甲烷气体的吸收光谱特性和模糊推理技术,给出了一种以单支1.33μm LED为激发光源,采用高性能16位微处理器MSP430作为斩波控制和模糊推理的检测仪智能前端系统的实现方案。研究表明,该方案的输出参数丰富,方案的提出为智能型光纤甲烷检测仪的模块独立化和高度集成化起到了积极的推动作用。

Based on the CH4 absorption spectrum and the fuzzy reasoning, a novel implementation of optical fiber CH4 detector intelligent front-end system was studied by the 1.33 μm LED and MSP430. MSP430 was used to realize the automatic alternate chopping and the fuzzy reasoning. The theory and experiment results show that the output parameter of the intelligent front end system is abundant, and the implementation highly enhances the integration and independence of optical fiber CH4 sensor.
