Embedded Energy and Power Management System

Abstract

In this paper, Embedded Energy and Power Management System (EEPMS) to manage power consumption, automatic meter reading in home area is described. The EEPMS is a single phase digital kWh power meter with embedded Zigbee modem which utilize the Wireless sensor network to send its power usage reading using information back to the energy provider wirelessly. At the power provider side they have the control to change priority of the devices when power distributed in low range. The concept of dynamic assignment of priorities to interrupts is discussed which reduces the time delay for a lower priority task which under some circumstances becomes a higher priority task. Slit of interrupt timings is also observed which can be used to improve the performance.
