基于传感器阵列的油品分层系统的研究与设计

针对目前油品含水率测量存在的油污的问题,设计了6电极电容传感器阵列,以此来解决单个或少量传感器探头易被油污污染,严重影响决策判断的问题.针对电路中漏电流问题进行了电路的改进,采用D触发器来控制两个互补时序的开关,比单纯用非门的方法能减少大概几十纳秒的电荷泄漏时间,能较好的改善漏电流的问题.设计了基于PC机WINDOWS操作系统的实验数据采集与分析系统,试验证明所设计的传感器阵列与数据采集系统能够达到预期的简单液体层次分离的效果.

The Design of Multi-layer Liquid Separation System Based on Sensor Array

A low cost transducer array based on the charge transfer principle is designed to resolve the problem that the sensor probes could be affected by the greasy dirt.The quality of two pairs of complement square waves working as 4 switch control signals is improved by using D trigger taking the place of not gate.In this way,the time of leaking charge can be ten nanoseconds less than before improved.An analyzing system based on WINDOWS operating system is designed.It is proved that the system composed of transdu...
