摘要
为了有效解决了探空仪在高空低温环境中遇到的传感器结露、结冰问题,采用双加热湿度传感器自动轮换交替加热来去除传感器污染,提高测量精度。在常温常压下对双加热湿度传感器进行加热实验,得出在额定电压下,传感器上升温度与响应时间的关系曲线,运用扩充响应曲线法求出双加热湿度传感器加热片的加热模型,通过对加热模型的分析,利用Fuzzy-PID进行加热控制,仿真结果表明利用Fuzzy-PID能够满足实际高空探测的要求。
In order to effectively solve condensation and icing problems of radiosonde in low - temperature environment at high altitude ,we use humidity sensor heated automatic alternately to remove pollution and improve the measurement accuracy. Heat ex- periments obtained the curve between rising temperature and responsible time on heated twin humidity sensor in normal temperature and pressure, by expanded responsible curve to obtain heated model of twin heated humidity sensor and analysis model. Through Fuzzy - PID control for heating, the simulation results show that the Fuzzy - PID control meet the practical requirements of measure at high altitude.
