Automatic Energy Meter Reading through Power Line Communication

Automatic Energy Meter Reading through Power Line Communication

This project deals with “Automatic Energy Meter Reading through Power Line Communication”. Presently in India Energy Meter reading is done through nominated officials by visiting the residential and commercial places. This project is proposed to change the existing energy metering by employing the Power line communication technology. Power line carrier communications take place over the same lines that deliver electricity.

This technique involves injecting a high frequency AC carrier into the power line and modulating this carrier with data originating from the remote meter or central station. Power Line Communications - transmits data over an existing high-voltage power line instead of requiring dedicated cabling. (PLC) can thus provide an inexpensive solution for transmitting data in a pre-wired location.
The solution for residential Automatic Meter Reading (AMR) consists of a host computer, a gateway interface and a low-cost Power Line Carrier (PLC) residential meter. LCD display showing the meter readings, date of bill payment and billing details. The system also incorporates a power cut feature, which can be activated when the consumer doesn’t pay the bill within the due date. The system performances become superior to conventional methods. Now this scheme becomes implementing able with advent fast computing devices.

REAL TIME BIOMEDICAL MONITORING SYSTEM

REAL TIME BIOMEDICAL MONITORING SYSTEM

The conventional methods to monitor the heartbeat has number of issues to deal with. Even the commercial wireless technology being employed has more complications and is offline. In this project, a generic real-time wireless communication system has been designed and developed for short and long term remote patient-monitoring applying wireless protocol. The primary function of this system is to monitor the temperature and heart beat of the patient and the data collected by the sensors are sent to the microcontroller. The microcontroller transmits the data over the air. At the receiving end a receiver is used to receive the data and it is decoded and fed to microcontroller, which is then displayed over the LCD display. If there is a dangerous change in patient's status an alarm is also activated.
