摘要
讨论长期处于海风、酸雨、沙尘等恶劣探测环境下,风速传感器启动风速的变化。采用试验分析的方法,利用M3DS型风速传感器自动化检定系统和EL15-1C型风速传感器,分别测量取自不同恶劣探测环境的风速传感器和全新风速传感器的启动风速数据。得到的数据显示:取自海风、酸雨、沙尘等恶劣探测环境的风速传感器启动风速远大于全新风速传感器启动风速。长期海风、酸雨、沙尘天气改变了风速传感器的机械结构,同时降低了风速传感器启动风速的鉴别阀。
The long-term variation of starting wind speeds of wind speed sensors is analyzed in such detection environment as sea wind, dust, and acid rain to provide the qualitative bases for the correction of meteorological data under low wind speed weather. By experiments, using the starting wind speed calibration instruments, a group of starting wind speed records about new wind speed sensor and the special working environment of wind speed sensors are obtained. The results indicate that the long-term working for in the environment of sea wind, dust, and acid rain will reduce the sensitivity of the starting wind speeds of wind speed sensors.
