This document proposes a remote online monitoring system for dams that uses sensors to monitor parameters like temperature, displacement, load, and stress in real-time. The sensor data is sent via GPRS to a computer server where it is stored and analyzed. This allows dam conditions to be monitored centrally without needing manual on-site measurements. The proposed system interfaces sensors with a PIC microcontroller that sends abnormal sensor readings via GPRS. Authorized users can then access the sensor data remotely for monitoring dam safety.

1. A REMOTE ONLINE MONITORING SYSTEM FOR DAM
Abstract:
Because of most dams are locating far away from the city, sparsely populated areas.
Many state parameters, such as temperature, displacement, load, acceleration, speed, stress and
tension, need to be real-time monitored. With the help of GPRS mobile network, the parameters
of the dam will be transferred to the computer server, so we can quickly and accurately grasp the
working conditions of the dam and discover hidden trouble timely in central control room. At the
same time, we can store all monitored data, analyzing the data, we can gather information in
control center.
Existing system:
At present there is no automated system in existence. Dam maintenance and
measurements are done manually. The disadvantage is that the measurements are done
periodically. Hence data may not be helpful at all times.
Proposed system:
In the proposed system, the DAM environment is monitored using various sensors. The
sensors include water level sensor, flow sensor and temperature sensor. The sensors are
interfaced with the ADC channel of the PIC microcontroller. RTC is also interfaced with the
system to make the system more real times. The measured values are stored in the data memory
along with the time. If any abnormality is recorded immediately the abnormality is uploaded in
Internet using GPRS technology. Once the abnormality is seen by the authorized persons they
can approach the system for reading the last recorded set of measured data from data memory
using a key.
