Abstract

The invention relates to machine vision light source control used in industrial product surface quality detection, and specifically to a digitalized wireless LED light source controller. The digitalized wireless LED light source controller comprises a hardware part and a software part, wherein the hardware part comprises an upper computer, a wireless serial port communication module, an embedded type control unit, a light source driving circuit, LED light sources, a display module and a power supply module; and the software part comprises upper computer software, an embedded type control unit program and an LED gray value regulation algorithm. An operator sends an instruction to the embedded type control unit through the upper computer software; and after the embedded type control unit receives the instruction and processes the data, the embedded type control unit outputs a PWM wave with the corresponding duty ratio so as to control the luminance of the LED light sources. The digitalized wireless LED light source controller is low in heating amount, reasonable in structure, capable of accurately and stably controlling the four paths of the LED light sources, and particularly capable of controlling the instruction data to adopt the non-contact type wireless input mode, so that the wiring difficulty is avoided, and the digitalized wireless LED light source controller is simpler to install in the actual installation process.

Description

technical field [0001] The invention relates to machine vision light source control for industrial product surface quality detection, in particular to a digital wireless LED light source controller. Background technique [0002] Machine vision system is a system that uses machines instead of human eyes to obtain images of objective things, and processes, analyzes and recognizes the acquired images through computer and image processing technology, including lighting, lenses, cameras, image acquisition cards and visual processors. , each part may affect the result of image processing, and even lead to the instability of the machine vision system. Among them, the light source controller is one of the most critical links. [0003] The existing light source controller has the problems of obvious heat generation and troublesome wiring between the control command input module and the controller. In the industrial field, due to the limitation of the installation environment, it is...
