A distributed power consumption measurement system and its applications

The paper presents a distributed power consumption measurement system using ZigBee based wireless point of load power meters. The software architecture of the system is based the D-Bus inter-process communication solution. It is shown in the paper that our D-Bus based solution is better from the point of view of reliability and programming language support than the widely used JAVA based OSGi framework. The system consists data analyses components also. Our example component applies hybrid model based detection algorithms to identify the operating state of power consuming devices We also introduce our initial results from the operation of the system, for example wireless communication problems and the consequences of them are presented. The primary application area of the developed solution is activity detection in ambient assisted living solutions and energy aware IT system management.
