Embodiment Construction

[0009] Such as figure 1 As shown, the invention provides an electric meter, including a detection unit, a display screen, an input unit, a single-chip microcomputer and a computing unit, the input unit sends signals to the display screen and the single-chip microcomputer, and the single-chip microcomputer sends signals to the display screen and the computing unit, and receives the computing unit and the signal from the detection unit.

[0010] The input unit is a mechanical keyboard or a touch screen.

[0011] It includes a signal transceiving unit, and the signal transceiving unit is connected with the single chip microcomputer.

[0012] The working process of this example: When a time period is input through the input unit, the single-chip microcomputer reads the power consumption detected by the detection unit during this time period and displays it on the display screen. When the unit price per kilowatt-hour is input at the same time, the single-chip microcomputer The to...

Abstract

The invention provides an ammeter which comprises a detecting unit, a display screen, an input unit, a single-chip microcomputer and a calculating unit. The input unit transmits signals to the display screen and the single-chip microcomputer. The single-chip microcomputer transmits signals to the display screen and the calculating unit and receives the signals transmitted by the calculating unit and the detecting unit. The ammeter has the advantages that information can be directly read by inputting data, and functions of the ammeter are increased.
