Method capable of displaying real-time electric quantity state and electronic scale

Abstract

The invention relates to a method capable of displaying a real-time electric quantity state and an electronic scale. The electronic scale comprises an electronic scale body and a rechargeable battery. The electronic scale is characterized in that a battery electric quantity monitoring circuit, a driving signal generation unit and a battery electric quantity display unit are arranged in the electronic scale body, the battery electric quantity monitoring circuit is used for monitoring the electric quantity state of the rechargeable battery, and the electric quantity state is displayed through the battery electric quantity display unit; the rechargeable battery is electrically connected to the battery electric quantity monitoring circuit, and the battery electric quantity monitoring circuit is connected with the battery electric quantity display unit after the battery electric quantity monitoring circuit passes through the driving signal generation unit; and the battery electric quantity monitoring circuit consists of a battery electric quantity monitoring unit, a single-chip microcomputer and an electric quantity prompting module. By adopting the method and the electronic scale, when a user uses the electronic scale, the battery state information can be accurately known; and when the electric quantity of the battery is low, a prompt can be automatically given out to prompt the user to charge in time, the situations that the power of the electronic scale is suddenly cut off when the electronic scale is in use and the use is influenced are effectively avoided, and long-term stable use is realized.

Description

technical field [0001] The invention relates to the technical field of power management in electronic scales, in particular to an electronic scale capable of displaying battery power status. Background technique [0002] As a commonly used measurement and weighing tool nowadays, electronic scales measure and display the mass of objects by using electronic technology.

[0003] At present, electronic scales also use sensor technology, electronic technology and computer technology to meet the requirements of fast, accurate, continuous and automatic weighing in real life, and effectively eliminate human errors at the same time, making it more in line with legal measurement management and industrial standards. Application requirements for production process control. Compared with ...

AI Technical Summary

Problems solved by technology

[0004] Existing electronic scales usually use batteries as a power source, but because there is no power display function, the remaining battery power cannot be displayed during normal use, so it is easy to suddenly run out of power and affect the user's use. At this time, if it is in an outdoor environment, For example, in non-indoor business places such as vegetable markets and roadsides, it will cause great inconvenience.
