Intelligent power control system — A case study of the lighting power in communal lavatories

In light of the demand for global greenhouse gas control proposed in Kyoto Protocol as well as promoting the efficiency of energy use, a power control system is proposed in this study. A lot of lighting power in communal lavatories is not managed and controlled that it is likely to be lit for 24 hours, once it is switched on. When there is no one using the lavatory but the lighting power is still on, abundant power waste is caused. If the number of people using the lavatory can be sensed and calculated as well as the lights can be automatically switched off when it is not in-use, the power could be economized for quality power management and waste preclusion. Moreover, if the data of power utilization could be transmitted to the server host and recorded in the database with remote connection, not only could the situation and the characteristics of power utilization be analyzed, but the switch time could also be intelligently self-regulated.
