Automatic energy supply systems of the multi-rate calculating type
First Claim
1. An automatic energy supply system of the multi-rate calculating type for controlling an amount of energy supplied to a customer comprising:
- a pulse generating integrating means coupled to an energy source for integrating said amount of energy supplied to a customer and for generating an electric signal whenever a predetermined unit of said energy is supplied;
a pulse converter means for converting said electric signal into at least one pulse signal;
a timer means for generating a time signal corresponding to a predetermined rate calculating interval;
a switching means coupled to said energy source for switching said energy supplied to the customer on and off;
a multi-rate calculation function unit comprising a plurality of element means for providing energy rate parameters and tax parameters;
a rate function unit comprising a rate element means for providing money parameters which represent an amount of money corresponding to a predetermined amount of purchased energy;
a rate detection selection unit comprising a rate detection member means responsive to said money parameter provided by said rate element means, said rate detection member means being a means for producing a rate signal corresponding to said predetermined amount of purchased energy; and
a multi-rate calculating unit means coupled to said switching means and responsive to said time signal, to said at least one pulse signal, to said rate signal and to said energy rate and said tax rate parameters provided by said multi-rate calculation function unit, said multi-rate calculating unit means being a means for providing a sum signal to said switching means which causes said switching means to switch off when said amount of energy supplied to the customer corresponds to said predetermined amount of purchased energy and to said parameters regarding energy rates and tax.

Abstract
According to the supply system, a customer purchases a chip corresponding to a predetermined amount of electricity from a power company and sets the chip in a control device installed in the customer house. The supply system comprises an integrating watthour meter which integrates the power consumed by the customer and generates a pulse signal for each unit of consumed power, a timer responsive to the output of the integrating watthour meter for producing a time signal corresponding to a predetermined rate calculating interval, a multi-rate calculating unit responsive to the timer signal and the pulse signal for independently calculating a plurality of operation rate elements an electric switch for supplying power to the customer, a rate detection selection unit including a rate detection member, a multi-rate calculation function unit including a plurality of elements which are set with various parameters regarding tax and rate and adapted to be combined with the multi-rate calculating unit for calculating the rate, and a rate function unit including a rate element set with an amount of power corresponding to the amount of purchased power and adapted to be combined with the rate selection detection unit for producing a rate signal corresponding to the purchased amount of power. The switch is controlled by the rate signal for supplying to the customer a predetermined amount of power.
