DE202008011291U1 - Energy meter for kWh and / or m3 with advance warning before tariff exceeding especially for saving energy in private households - Google Patents

Abstract

Measuring device - Microprocessor (P) controlled - for monitoring Consumption of electricity, gas or water especially in private households characterized; that during a presettable Period related energy before reaching tariff limited Amount to the consumer over external device (W) transmits a warning.

Description

1.) State of the art

The electricity industry knows the concept of the maximum counter, which is used especially in industrial companies to favorable conditions (tariffs) for the Supply of electrical energy. Here the utilization plays the supply network (load diagram) a role, the role of the counter in it exists before reaching a collectively agreed load (kWh) warn, bezw. Switch off individual consumers temporarily by using certain auxiliary devices.

The Measuring cycles are usually ¼ tel hourly. protocol becomes common printed.

2.) Underlying problem

The The problem underlying the invention is in the necessary today Energy saving in households that prevail at the prevailing indifference the consumer fails and has to be financially felt. to succeed respectively.

Counter readings in progress It seems expensive to control and therefore not very promising.

3.) Problem solving

The The present invention uses the maximum counter described under 1.) Template for a Microprocessor controlled solution and allows thus a "household counter" not only for consumption recording electrical energy but also for or gas or water.

Electricity- or energy suppliers tailor made for it Offer rates (eg monthly "flatrates").

The Measuring cycles are optionally adjustable z. Eg - 24 h or month. Timing via DCF 77

One mechanical roller counter is additional can be used for a multifunctional display. Communication takes place wireless or wired for Warning of tariff violation (set in the flatrate) and for remote reading

The gauge must be calibrated by PTB. subject.

4.) Achieved benefits

• - Energy Savings due to clear specification of the delivery quantity and warning of exceeding
• - Possible financial Burden. elevated Attention.
• - energy conservation, natural reserve
• - Selection the sensor unit also allows consumption measurement for Gas or water
• - Economic Production by large series

The schematic diagram on page 4 of 4 explained the function of the measuring device

Of the sensor (F) records the measured values. He delivers these to the processor (P) available which controls the entire functions of the measuring device. Timing and calendar function are fed here by the DCF 77 radio service. The converter stage (U) prepares data and forwards it to the display (D) and for storing the memory stage (S) and the mechanical roller counter (Z) to. The customer can from stage (A) by means of button its consumption check. Wireless or - optionally - via cable becomes the warning device (W) activated when tariff exceeded threatening.

Claims (10)

Meter - Microprocessor (P) controlled - for monitoring the consumption of electricity, gas or water especially in private households characterized ; the energy purchased during a pre-settable period of time, before reaching a tariff-limited amount, transmits a warning to the consumer via external device (W). gauge under 1), characterized in that a warning before exceeding the tariff - timely adjustable - verbal or by means of signal wireless or wired to an external warning device (W) can be issued. gauge under 1) and 2), characterized in that it as a verifiable household meter the Energy suppliers individual tariff design in the form of "flatrates" allowed and so can directly serve the desired energy savings. gauge under 1) to 3), characterized in that the use of the equipment by choosing the feeler (F) can be adapted to the medium to be measured. gauge under 1) to 4), characterized in that because - processor-controlled - a device under Use appropriate software to measure multiple media simultaneously and store the respective results in memory (S) and from it can call.
