混合式水位测量方法的探究

Research on An Integrated Measurement for Water Level

针对测站特殊环境条件下,大变幅水位测量难度较大的问题,提出一种综合采用机械格雷码水位传感器和电子水尺传感器的测量方法,利用2种水位传感器的测量优势及特点,分别解决高低水位的测量难题,再通过新型水文遥测数据终端整合衔接得到水位值。该方案应用于浙江省兰溪市洋港水文站并得到验证,较好地实现了单一类型水位传感器难以达到的效果。

Under environment of field station, large stage fluctuation range will increase difficulties in water level measurement. The paper provides a measurement by mechanical Gray encoding water level sensor and electronic gauge. Application of two water level sensors can respectively solve problems of high and low water level, then water level value can be given through integration of a new type remote terminal unit. The measurement has already been used for Yanggang water-level gauging station in Zhejiang province. Its application verifies that the measurement can achieve better results than that of single water level sensor.
