Abstract

The invention discloses a multi-range automatic gear shifting device. The multi-range automatic gear shifting device consists of an integral proportioner, a multistage stepper, a data distributor and a gear distributor which are connected in sequence. An acquired pulse signal is calculated by the integral proportioner and input to the data distributor and the multistage stepper so as to form a gear signal for controlling the data distributor and the gear distributor; a numerical signal is selected and sent to an output end; a unit signal matched with the numerical signal is selected and sent to the output end; and the numerical and unit signals are sent to an instrument for displaying measurement data and unit of measurement. The multi-range automatic gear shifting device is especially suitable for a household power meter to directly measure power, so that troubles of determining a range by pre-estimated power, turning power off and changing the range (shifting gear) are eliminated, various potential hazards caused by forgotten gear shifting or incorrect gear shifting are avoided, and a household measurement instrument can conveniently finish safe multi-range accurate measurement.

Description

Technical field [0001] The invention relates to a multi-range automatic shifting device, which is especially suitable for direct measurement of power by a household power meter, which saves the trouble of determining the range by estimating the power in advance, and the trouble of power failure and changing range (shifting), and avoids forgetting to change gears. It is convenient for household measuring instruments to realize safe and accurate measurement of multiple ranges. Background technique [0002] At present, it is known that the power consumption of household appliances is an important indicator, which is closely related to electricity bills, energy saving and quality of life. Although household appliances have instructions when they leave the factory (such as 8-watt energy-saving lamps, 1000-watt induction cooker), it is actually difficult to measure. How big is the power consumption? People don't know that this is not conducive to the rational use and purchase of ...
