Algorithm for reducing work power consumption of seven-segment nixie tube

Abstract

The invention discloses an algorithm for reducing the work power consumption of a seven-segment nixie tube. The algorithm includes: the scanning mode of scanning an n-bit seven-segment nixie tube in a segmented manner is employed, since one nixie tube has seven segments in total, the n nixie tubes have 7*n segments in total, here the required time for scanning the one nixie tube is defined as t, the work voltage of the nixie tube is defined as U, the required current for scanning one segment of the nixie tube is defined as I, P represents energy consumption, and the energy consumption for scanning the n seven-segment nixie tubes by the scanning mode is: P=U*(I*t / 7)*(7*n)=n*U*I*t. According to the algorithm, the scanning mode of scanning the n seven-segment nixie tubes in a segmented manner is employed, software algorithm programming is matched, each nixie tube has seven segments in total, so the n nixie tubes have 7*n segments in total, the energy consumption of the scanning mode is n times as much as that of each nixie tube, compared with the condition that according to the conventional scanning mode, the energy consumption of the n nixie tubes is 7n times as much as that of each nixie tube, the energy consumption is reduced by 7 times, the energy is greatly saved, the algorithm is completed through a program algorithm, any peripheral component does not need to be added, the increase of the cost for customers is prevented, the adaptability is high, the application is wide, and the energy consumption is low.

Description

technical field [0001] The invention relates to the technical field of seven-segment digital tubes, in particular to an algorithm for reducing the working power consumption of seven-segment digital tubes. Background technique [0002] Seven-segment digital tubes are widely used in home appliances and industrial control, such as displaying temperature, quantity, weight, date, time, etc., and have the advantages of eye-catching and intuitive display. For some battery-powered products, such as kitchen scales, water temperature meters, electronic clocks, etc., due to the relatively high power consumption of digital tubes, end users frequently replace batteries to meet the normal work of the product. When the n-digit digital tube is displayed, when power is supplied, the working current of the n-digit seven-segment digital tube is scanned bit by bit. The specific method is to first scan the 7 segments of the first digital tube, and then scan the 7 segments of the second digital t...

Like some battery-powered products, such as kitchen scales, water temperature meters, electronic clocks, etc., due to the relatively high power consumption of the digital tube, the end user frequently replaces the battery to meet the normal work of the product

When the n-digit digital tube is displayed, when power is supplied, the working current of the n-digit seven-segment digital tube is scanned bit by bit. The specific method is to first scan the 7 segments of the first digital tube, and then scan the 7 segments of the second digital tube. Taking this as an example, scan the next digital tube until the n-digit digital tube, which can be understood as scanning in columns. The energy consumption of the n-digit digital tube in this scanning method is n times the energy consumption of each digital tube. Each segment of the digital tube 7n times, but this scanning method will lead to relatively high power consumption, which limits the market application of such products
