图2图3图1图4图5方案的论证与比较1.传感器检测滴速部分方案一 : 使用电容式接近开关。电路集成度高,使用继电器输出,输出信号标准,电路简单。但其工作原理是根据电容中介质的改变对外产生开关量,经过调试发现由于瓶中液体和周围环境随时会发生变化,很容易触发传感器,而使系统
Figure 2 Figure 3 Figure 1 Figure 4 Figure 5 program demonstration and comparison 1. Sensor detection drip part of the program one: the use of capacitive proximity switches. High circuit integration, the use of relay output, the output signal standard, the circuit is simple. But its working principle is based on changes in the capacitance of the media to generate external switch, after debugging found that the bottle of liquid and the surrounding environment will change at any time, it is easy to trigger the sensor, leaving the system
