Problems solved by technology

When the digital tube works in a dynamic scanning display mode, the driver chip must stop the digital tube scanning when receiving the data collected by the sensor. Due to various interference sources of the sensor, the digital tube will display unstable display brightness and display wrong information.
[0003] In view of the above problems, the present invention proposes a method for controlling the display of the digital tube to solve the problem that the digital tube has poor display brightness stability and displays wrong information due to the characteristics of the digital tube drive chip itself

Embodiment Construction

[0025] The present invention will be further described below in conjunction with drawings and embodiments.

[0026] In the technical solution of the present invention, the nixie tube works in a dynamic scanning display mode, aiming at the attribute characteristics of the drive chip itself (when receiving the data collected by the sensor, the nixie tube must be stopped from scanning), a targeted algorithm is used to write to the drive chip. The data is processed to make up for the interference caused by various interference sources of the sensor, and to solve the problems of unstable display brightness and wrong information displayed by the digital tube. The process that the present invention controls nixie tube display is divided into three steps:

[0027] 1) Obtain the sampling signal;

[0028] 2) performing filtering processing on the sampled signal by using a recursive average filtering algorithm;

[0029] 3) The filtered signal drives the digital tube to display.

Abstract

The invention discloses a method for controlling the display of a nixie tube. The display of the nixie tube is controlled through precise signal acquisition, acquired signal filtering and special signal processing in display. The implementation process is simple, the stability of the display of the nixie tube is improved, and the generation of error messages is minimized.

Description

technical field [0001] The invention relates to the technical field of digital tube display, in particular to a method for controlling digital tube display. Background technique [0002] As a component with information prompt function, the digital tube is widely used in many fields, such as automobiles, home appliances, instruments and meters, etc. The display of the digital tube is divided into static display and dynamic scanning display, and the display information comes from the signals collected by various sensors. Since the static display will occupy more processor I / O lines, it is generally only suitable for applications with fewer display digits. When the digital tube works in a dynamic scanning display mode, the driver chip must stop the digital tube scanning when receiving the data collected by the sensor. Due to various interference sources of the sensor, the display brightness of the digital tube will be unstable and display wrong information. [0003] In view o...
