GSM BASED POWER FAILURE INDICATOR

Abstract:
            Embedded system is a specialized computer system that is part of a larger system or machine. Typically, an embedded system is housed on a single microcontroller board with the programs stored in ROM. Virtually all appliances that have a digital interface -- watches, microwaves, VCRs, cars -- utilize embedded systems.
          GSM (Global System for Mobile communications) is an open, digital cellular technology used for transmitting mobile voice and data services. GSM differs from first generation wireless systems in that it uses digital technology and time division multiple access transmission methods. GSM is a circuit-switched system that divides each 200 kHz channel into eight 25 kHz time-slots; GSM supports data transfer speeds of up to 9.6 kbit/s, allowing the transmission of basic data services such as SMS (Short Message Service). Another major benefit is its international roaming capability, allowing users to access the same services when traveling abroad as at home. This gives consumers seamless and same number connectivity in more than 210 countries. GSM satellite roaming has also extended service access to areas where terrestrial coverage is not available.
             This project is used to indicate power failure occurs in industries. For industries they need continuous power supply for fabrication. If a power failure occurs means the production will be stopped, time delay increases for finishing fabrication. In some cases we can loss consumer due to unsatisfactory. Our project aim is to detect the power failure and take reflex action to solve the problem with help of modem communication. The power failure will be intimated to the microcontroller it drive the gsm modem to send a text message to the concern person mobile number which was already programmed in controller. If he got a messages power failure related message and then take action to turn ON generator manually.
