摘要
依照精确、可靠、稳定的原则,设计点滴智能控制系统。利用步进电机的可控性、高精度性和红外光发射接收检测传感元件3DU的高灵敏性,以及89C51单片机的可编程性进行综合设计。实现了由主站控制多个从站的有线监控系统,根据实际需要,通过MAX485扩展出所需的从站数目。监控系统通过键盘控制液体点滴速度,并可自动报警;主站和从站间的通信实时性好。
A drop - intelligent - control system is designed. The system combines the controllability and high precision of the step - machinery and high sensitivity of 3DU, the infrared ray radiating - receiving detective sensor, and realizes the function of the single main station monitoring the muhi -substations. If needed, it can expand the number of the sub - stations through MAX485. The liquid dropping speed, controlled by the key board of the monitoring system, can between the main station and substations. alarm automatically. It can communicate efficiently
