摘要
通过对遥感式激光甲烷检测仪测量原理的分析,采用半导体制冷器温控技术,结合带有Smith预估算法的模糊PID温度补偿算法,探究了遥感式激光甲烷检测仪对温度变化的抗干扰性能,并进行试验验证。结果表明:温度补偿优化前,样品在0~40℃环境温度条件下测量最大相对误差达到13.98%,且随着温度上升,相对误差呈增大趋势;采取了温度补偿技术措施后,样品测量的最大相对误差仅为3.91%,测量精度得到显著提升。
Through the analysis of the measurement principle of remote sensing laser methane detector, the anti-interference performance of remote sensing laser methane detector to temperature change was explored by using semiconductor cooler temperature control technology and fuzzy PID temperature compensation algorithm combining with Smith prediction algorithm. Then, experiments were conducted for verification. The results show that before the optimization of temperature compensation, the maximum relative error of the samples measured at 0-40℃ ambient temperature reaches 13.98%, and the relative error increases with the increase of temperature. After adopting the temperature compensation technology, the maximum relative error of the samples is only 3.91%, and the measurement accuracy is significantly improved.
