Power saving mobile monitoring system on architectures

Power wastage is one of the most serious problems at present. The slogan ldquoturn off lights when not in userdquo has long been going around, but lights turned on in unoccupied rooms are frequently seen, particularly in public agencies or schools. The power line communication protocol frame work differs from ones used in the past such as X-10 [1], CEBus [3], LonWorks [6], etc. This system is intended for public spaces, where efficient management and control on lighting devices are implemented. Hopefully, simple circuit designs will help to achieve the purpose of power saving. By means of existing internal power line of buildings as communication media, module inductive circuits are compatible with current power switches. Through the system power lines and RF communication techniques, all school luminaries are managed by PDA remote monitoring method. Lights not in use are switched off to achieve power saving.
