Watt-hour meter display for informing consumer of energy consumption
This patent describes a system associated with an electric meter for displaying real time data for a consumer regarding consumption of electricity for a special use in a home having ac supply lines with a plurality of outlets, the system comprising: a detector means for sensing on the order of 200 equally spaced marks on the circumference of a surface of a rotating disk within the electric meter and for generating meter signals corresponding thereto; means for applying the meter signals as high frequency electrical signals on the ac supply lines; means capable of being plugged into any outlet of the a.c. supply lines for receiving the high frequency signals and generating digital meter pulses; a clock means for generating digital time pulses representative of real time; a microprocessor means including a first counting means for counting the digital meter pulses and a second counting means for counting the digital time pulses to define successive fixed time period, each fixed time period being on the order of 5 seconds in duration; and a display selector for controlling data being displayed by the microprocessor means on the display means and including a total use display setting and a special use display setting.
