Abstract

The invention provides a self-adaptive dimming system and a self-adaptive dimming method thereof. The self-adaptive dimming system comprises an infrared tube array module, an AD sampling module, a self-adaptive controller module, an MCU module and an FPGA module, wherein the AD sampling module conducts AD sampling on an output end of an infrared tube array and sends an AD sampling value to the self-adaptive controller module; and the self-adaptive controller module controls the luminous intensity of a transmitting end of the infrared tube array module by adjusting the duty ratio of a PWW signal. According to the self-adaptive dimming system, the self-adaptive controller module adjusts the duty ratio of the PWM signal to control the luminous intensity of the transmitting end of the infraredtube array module, so that the dimming effect is achieved; and the self-adaptive dimming system has the advantages of high anti-interference capability, high portability and the like, and has a goodapplication prospect in the field of electronic application.

Description

technical field [0001] The invention relates to an adaptive dimming system, in particular to an adaptive dimming system and an adaptive dimming method thereof. Background technique [0002] In the machines in the financial field, infrared tubes are widely used. For example, infrared tubes can count banknotes during banknotes, or separate banknotes of different denominations during banknotes, or count banknotes during work. To judge the skew, it is also possible to judge whether the system is blocked during the banknote transfer process. However, sometimes the emission end of the anti-radiation tube emits too much light, and the light will penetrate a banknote, and its state cannot be judged normally; [0003] Therefore, the application of adaptive dimming in the financial field is essential. Contents of the invention [0004] The object of the present invention is to provide an adaptive dimming system and an adaptive dimming method thereof, so as to solve the problems ra...
