ABSTRACT
Intelligent Energy Saving System can be used in places like where lighting is very important. The libraries will be well illuminated with many lamps. When people are not present at a reading place the lighting can be made OFF and when they are present, the lighting made ON. All these can be done through by Dimming circuit and PIR sensor.
If a person entering to the monitored area, the PIR sensors activates and sense the person, gives to the micro controller. The Infrared energy emitted from the living body is focused by a Fresnel lens segment. Then only the PIR sensor activates. After sensing the person LDR checks the light intensity of the monitored area, whether it is bright or dark. Depending on the LDR output, the lamp may be ON / OFF by using Dimmer circuit.
By using this system we can adjust the speed of Fan according to the room temperature measured by Thermostat, which is connected to the micro controller.
Existing System
To solve the energy shortage and green house problem, all nations reach to the common sense to positively promote energy-saving activity. To save the electrical energy we have to manage all the environmental parameters such as temperature, humidity, luminance, and quality of air in the living space and probably adjust all the power-consuming facilities dynamically. For example, if the temperature in the living space is lower than 26℃, the air conditioner would keep closed, and if there is no person in the space all the facilities ought not be opened. Reference investigated the luminance regulation techniques so as to improve the efficiency of lighting energy conservation. Reference proposed the study on the difference of energy conservation management between building and indoor-decoration Luminance. It also revised the luminance energy conservation standard with the statistics of luminance loading and electricity density /per area unit of office in Taipei city so as to improve the luminance energy conservation strategies
Proposed System
From the description above, we attempt to design an intelligent energy conservation system with ontological information agent which is an intelligent agent technique proceeding data mining, events analysis, and quickly response system. The system displays all the sensor information and environmental parameters on the server computer screen, and through the comparison between the real-time collected data with database to make decision and proceed feedback control to all power-consuming facilities. Finally, the system is built in a campus building as a target for the effectiveness evaluation of the intelligent energy conservation system.
