Abstract

The invention discloses a two-digital nixie tube display system of a high-voltage live display device. The display system comprises a power module, a reset circuit module, a clock circuit module, a single-chip microcomputer, a program module, and a nixie tube display module. The reset circuit module comprises a first-stage system power supply module, a first-stage system peripheral power supply module, several second-stage system peripheral power supply modules, a main control unit power supply module, a power supply management system, a power supply management system power supply module and a main power supply. Through the above mode, the display system of the invention can use one two-digital nixie tube to achieve display and switching of a timing function, has various functions, is flexible in operation, and is low in failure rate.

Description

technical field [0001] The invention relates to the field of electricity, in particular to a two-digit digital tube display system of a high-voltage charged display device. Background technique [0002] LED digital tube (LED Segment Displays) is a "8"-shaped device composed of multiple light-emitting diodes packaged together. The lead wires have been connected internally. It is only necessary to lead out their individual strokes and common electrodes. The number of commonly used segments of LED digital tubes is generally 7 segments, some plus a decimal point, and the other is similar to the 3-digit "+1" type. There are half digits, 1, 2, 3, 4, 5, 6, 8, 10 digits, etc. LED digital tubes are divided into common cathode and common anode according to the connection method of LEDs. Understand these characteristics of LEDs, It is very important for programming, because different types of digital tubes have different programming methods in addition to their hardware circuits. The...
