Abstract

The invention discloses a digital LED (Light-Emitting Diode) light source controller facing the machine vision, relates to an LED light source controller and aims to solve the problems that for an existing light source controller, the simultaneous control of various control signals cannot be implemented and a light source flash mode is single. The external control, keyboard and serial port trigger signal input ends of a core control unit are respectively connected with the external control, keyboard and serial ort trigger signal output ends of external control, keyboard and serial port trigger modules; the PWM (Pulse Width Modulation) and stroboscopic signal output ends of the core control unit are respectively connected with the PWM and stroboscopic signal input ends of PWM mode and stroboscopic controllers; the PWM signal output end of the PWM mode controller and the stroboscopic signal output end of the stroboscopic mode controller are respectively connected with the PWM signal input end and the stroboscopic signal input end of an LED driving module; and the driving signal output end of the LED driving module is connected with the driving signal input end of an LED light source; and the digital LED light source controller facing the machine vision can be suitable for an E-type magnetic material detection platform.

Description

technical field [0001] The invention relates to an LED light source controller, in particular to a digital LED light source controller. Background technique [0002] Machine vision is an interdisciplinary subject involving electronic engineering, digital image processing, pattern recognition and many other technical fields. After more than 40 years of development and research, it has become one of the most eye-catching subjects in the field of artificial intelligence. Generally speaking, a machine vision system includes a lighting system, lens, camera and image card, and the quality of each component has an impact on the quality of the image. The light source control module is one of the most critical parts of machine vision applications, which can directly affect the image quality and application effect to a large extent. In the E-type magnetic material testing platform, the light source controller is also one of the most critical links. The existing light source controll...
