Remote Supervisory System of Classroom Lighting Based on LonWorks Fieldbus

A remote supervisory system of classroom lighting based on LonWorks fieldbus is presented, which controls the switch state of lights and the number of lights to turn on, achieving the purpose of energy saving. The administrator can remotely know the situation of each classroom, and be able to perform manually control. The experiment results show that the proposed supervisory system has the qualities of easy to implement, high reliability, and easy to expand.
