摘要:
针对现有的常用水位计在水位快速变化场合应用的不足之处，该文设计了一种可快速跟踪水位变化过程的新型低功耗浮子水位计。介绍了该浮子水位计的组成结构，详细描述了采用三相循环编码的水位编码器将物理水位信号转换为电信号的原理以及信号的编解码方法，给出了针对该浮子水位计输出信号的检测电路及软件处理流程，说明了该水位计为什么能够快速跟踪水位变化以及在水位的实时监测过程中实现低功耗，同时给出了该水位计在水位频繁波动场合的低功耗应用实例。
Abstract:
Briefly analyses the shortcomings of the existing common water level gauge in the situation of rapid change of water level,and designs a new type of low-power float water level gauge which can quickly track the process of change of water level.The structure of the float water level gauge is introduced,and the principle of transforming physical water level signal into electrical signal by three-phase cyclic coding water level encoder and the coding/decoding method of signal are described in detail.The detection circuit and software processing flow for the output signal of the float water level gauge are also given,which explains why it can track water level changes quickly and realize low power consumption in the real-time monitoring process of water level.An example of low power consumption application of the water level gauge in the case of frequent fluctuation of water level is also given.
