www.svsembedded.com SVSEMBEDDED [email protected], CONTACT: +91-- 9491535690, +91-- 7842358459 AIM: The main aim of this project is to monitor and record key operation indictors of a distribution transformer like load currents, voltages and ambient temperatures.

PURPOSE: The purpose of this project is to send the information to the mobile by using GSM technology about the distribution transformer operations like load currents, voltages and ambient temperature. If there is any abnormality or an emergency situation the system sends SMS (Short Message Service) messages to designated mobile telephones.

DESCRIPTION: This project presents design and implementation of a mobile embedded system to monitor and record key operation indictors of a distribution transformer like load currents, voltages and ambient temperatures. The proposed on-line monitoring system integrates a Global Service Mobile (GSM) Modem, with stand alone single chip microcontroller and sensor packages. It is installed at the distribution transformer site and the above mentioned parameters are recorded using the built-in 8-channel analog to digital converter (ADC) of the embedded system. The acquired parameters are processed and recorded in the system memory. If there is any abnormality or an emergency situation the system sends SMS (Short Message Service) messages to designated mobile telephones containing information about the abnormality according to some predefined instructions and policies that are stored on the embedded system EEPROM. Also, it sends SMS to a central database via the GSM modem for further processing. This mobile system will help the utilities to optimally utilize transformers and identify problems before any catastrophic failure.

TECHNOLOGY: Every system is automated in order to face new challenges in the present day situation. Automated systems have less manual operations, so that the flexibility, reliabilities are high and accurate. Hence every field prefers automated control systems. Especially in the field of electronics automated systems are doing better performance.

If you travel in parts of world, GSM is only type of cellular service available. Instead of analog services, GSM was developed as a digital system using TDMA technology.

SOFTWERE USED: KEIL ASM EMBEDDED

HARDWARE: Micro controller Power supply Sensors ADC GSM modem MAX 232 Appliances Relay DC Fan

RESULT: This kind of project is very effective and can be used for providing safety to the distribution transformer.
