水位检测系统的控制水位检测系统的控制水位检测系统的控制水位检测系统的控制电路电路电路电路?4418501?200413185006??I?PLC?PLC?关键字??II Abstract Water level detection is widely used in our usual life and many industry fields,such as rivers or lakes,water tank?water tower,groundwater,hydropower station,selling water by self.The situations need water level detection to know the changes of water level.In these days,water level detection system has been widely used at home and abroad.Water level detection is the sum of the data cellection,saving,transmission and dealing,which has many methods,such as manual detection,sensor detection and so on.The water level detection system works through the changes in water level on-or off circuit to realize connection or breaking of power,controying the warning system in working or not.The system controls the electric way in many forms.System control circuits take many forms,the transistor,designed by the on-circuit or to control the opening and closing,the impact of the LED light-emitting diodes,which play a direct role in the visually and hearing.At the same time,the sigh of real water level can be changed into controller PLC.By linking the communications portal and configuration software can simulate real water level in order to know the situation of the water level.Keyword:detection;system;control the water level;circuit ?III?U?V I?A R?C?F w?n??IV?帮?.1 1.1?.1
