Display method of low-power smart electric meter

Abstract

The invention discloses a display method of a low-power smart electric meter. The low-power smart electric meter comprises a data acquisition and measurement unit, a data processing control unit, an electronic ink display unit, and a communication unit. The data acquisition and measurement unit is set inside the smart electric meter and used for acquiring data of the time and power flow information of the smart electric meter, and includes a power meter and an internal clock. The power meter is an electromagnetic induction meter, a pulse signal meter or an electronic meter. The information can be displayed for a long time without power supply. No backlight source is needed. The consumption of backlight sources is saved. The battery energy consumption of the smart electric meter is reduced. Lower power consumption is achieved.

Description

technical field [0001] The invention relates to a smart meter with an electronic screen for displaying electricity consumption and metering of the meter, in particular to a display method for a low-power smart meter. Background technique [0002] At present, the smart meters with electronic screen display on the market use LCD screens, referred to as LCD smart meters. LCD screen smart meters are generally powered by batteries. They have the functions of measuring electric energy through fluid metering sensors, using LCD screen electronic display, measuring and controlling user electric energy according to product functions, automatically completing step-by-step electricity charges, and storing meter data; using batteries Power supply, especially strict requirements on the power consumption of smart meters; [0003] The current use of LCD screen smart meters has the following deficiencies or defects: [0004] 1. In order to reduce power consumption, the smart meter with LCD...

AI Technical Summary

Problems solved by technology

[0004] 1. In order to reduce power consumption, the smart meter with LCD screen usually does not display on the LCD screen, and only displays the data once when the user triggers it (by swiping a card or button, etc.), which is inconvenient for the user to check the power consumption;

[0005] 2. The LCD screen also consumes battery power when it is not displaying data, resulting in high overall power consumption of the smart meter and not saving energy;

[0006] 3. Especially when the smart meter fails, because the LCD screen does not display information such as the total power consumption before the failure, when the faulty meter is replaced on site, it is impossible to determine the customer's electricity consumption and make settlement, which will cause problems for users and the meter. Consumption disputes between management departments due to the inability to determine electricity consumption on site limit the promotion and application of electronic meters without mechanical dials
