Automatic Dam Gate Control System with Caution Alarm Using ARM7

Abstract

Water level in a dam needs to be maintained effectively to avoid complications., the quantity of water released is hardly ever correct resulting in wastage of water & it is impossible for a man to precisely control the gates without the knowledge of exact water level and water inflow rate. This isa mechatronics based system, which will detect the level of water and estimate the water inflow rate in a dam and thereby control the movement of gates automatically. this a mechanical arrangement is made at minimum and maximum levels of water level,This system consists of a set of sensors connected to a stepper motor through an 8-bit microcontroller.This microcontroller operates the H-Bridge which in turn control the operation of the DC motor i.e. switches on the DC moving it in a clock wise direction. The water level and rate of inflow is detected based on the feedback from the sensors used. Based on this data, the level of dam gate can be automatically controlled using a DC motor. When the Dam gate is opened i.e. if the water level of the Dam exceeds then automatically Dam gate will be opened; then nearby villages can heard the sound of siren using RF technology. When the siren(which is placed at villages only).
