摘要
自然界中的水含有电解质,利用水的这一特性与数字电路编码、译码技术相结合,用交流信号作为检测信号降低腐蚀现象的发生。为此设计出了一种新型的数字化水位测量传感器,能够有效提高水位传感器的精度和抗腐蚀能力,通过简单清晰的界面实现了水文数据的采集实时监测。文中主要研究水的导电特性,水位的数字化自动检测的编译码电路及防腐蚀电路设计及原理,对水位的数字化自动检测的采集程序及原理阐述。
The natural water contains electrolyte, which can be used together with the digital circuit coding and decoding technology, and the AC signal as the detection signal to reduce the corrosion. Based on this, a new digital water level sensor is designed. The precision and corrosion resistance of the new sensor are greatly improved. Through the simple and clear interface, the hydrological data collection and real-time monitoring are carried out. The research is mainly on the conductivity of the water, the principle and de- sign of the coding and decoding circuit of the digital automatic detection of water level, and the corrosion resistance circuit. The col- lection procedure and principle of digital automatic detection of water level is also elaborated.
