摘要
阐述了用压阻式液位传感器测量城市地下水位的一种方法 ,并对所测得数据以数字信号的形式通过市话线路传输进行了较详细地讨论 .该系统和目前人工测量水位的方法相比 ,节省了大量的人力 ,提高了工效 。
A new method to measure groundwater levels of cities by liquid sensor of piezoresistance is introduced.The transmission of measured data through telephone lines in the form of digital signal is discussed in detail.Compared with the current manual method to measure the groundwater level, the developed system has the advantages of saving labour and increasing efficiency.It offers a better way to manage the municipal resources of groundwater.
