37. Intelligent Control via Power-Line Carrier for Illumination and Air Condition in Buildings

This paper establishes the monitoring system of advanced metering infrastructure by power line carrier. The communication between these modules is accomplished with power lines. The master module consists of a signal transform circuit, a LCD circuit and a keyboard circuit. The master module can measure the real-time states, including the voltage, the current, the real power and the reactive power, etc.,. The control modules can be divided into types, one is air conditioning control and another is illumination control. Each control module consists of a signal transform circuit, an AVR microprocessor, a keyboard decode circuit, a LCD circuit and a power line carrier circuit. It has the functions of local and remote monitors. The air conditioning control module is installed an infrared rays control circuit for the air condition device, and the illumination control module is added a power control circuit for the illumination load.
