本系统为一个液体点滴速度检测与控制装置。在滴斗处,系统可以检测当前点滴速度,并通过数显装置将其动态地显示出来。系统通过步进电机控制储液瓶的高度,从而控制点滴速度,设置速度通过键盘设定并显示。最大滴速调整时间约为2分钟。当储液瓶内液面高度降到警戒值(2～3cm)以下和上升到警戒值以上时,能发出报警信号。以上面所述装置为一个结点,我们还建立了一个由PC控制16个从站的监控系统。
The system is a liquid drip speed detection and control device. At the hopper, the system can detect the current dripping speed and display it dynamically via the digital display. System through the stepper motor control bottle height, thereby controlling the drip speed, set the speed through the keyboard to set and display. The maximum drip rate adjustment time is about 2 minutes. When the liquid level in the liquid bottle drops below the warning level (2 ~ 3cm) and rises above the warning level, an alarm signal can be issued. With the device described above as a node, we have also set up a monitoring system that controls 16 slaves by the PC.
