本文介绍城市实用排水泵站的微机监测控制系统以及硬件和软件设计。本系统可对泵站的水位、流量、温度、电机的电流、压电、功率等参数进行监测,并按照进口水位的情况控制各泵的开停。且根据泵站的工艺要求对四台水泵采用不同的开停顺序。文中介绍的上、下位机之间的通讯方式,具有非常简单的结构,几乎不需要硬件投资。在接口电路的设计上也有一些独特的方法。
This article introduces the city’s practical drainage pump station computer monitoring control system and hardware and software design. This system can monitor the pump station water level, flow rate, temperature, motor current, piezoelectricity, power and other parameters, and control the start and stop of each pump according to the imported water level. And according to the technical requirements of the pump station on the four pumps with different start-stop sequence. The article describes the communication between the upper and lower computer, has a very simple structure, almost no hardware investment. There are also some unique ways to design interface circuits.
