LED light source control system based on microcomputer control

Abstract

The invention provides an LED light source control system based on microcomputer control. The LED light source control system based on microcomputer control can avoid occurrence of light offset during a normal light modulation simulation process, and can accurately control the degree of light modulation. The LED light source control system based on microcomputer control includes a singlechip MCU module, a constant current voltage stabilization module, a 24V switch power supply module and a light source drive circuit module. 220V AC power supply output is connected with a switch power supply and generates 24V voltage output; the 24V voltage output is divided into two channels of connection, wherein one of the two channels is connected with a 7805 voltage stabilization chip module and the other channel is connected with an LM2596 chip; the output of the LM2596 chip is directly connected with the light source drive circuit module; an output end of the 7805 voltage stabilization chip module is divided into three channels of connection, wherein one channel is connected with a photoresistance sensor; the other channel is connected to an RS232 download chip; and the last channel is connected with the singlechip MCU module; and the output of the photoresistance sensor and the output of the RS232 download chip are also connected with the singlechip MCU module.

Description

technical field [0001] The invention belongs to the field of industrial production, in particular to a microcomputer-based LED light source control system. Background technique [0002] At present, in the industrial production process, manual identification of the direction of the plug head and the TB1 tube is still used before manual assembly, so that the assembly result has a lot of subjective factors, low work efficiency, and low accuracy; in addition, the work intensity is high, and it is easy to cause staff fatigue, etc. Factors, have not been able to achieve a good assembly effect. With the improvement of automation equipment and industrial image processing capabilities, a new technology-machine vision has gradually formed in the industry. [0003] The machine vision system mainly includes two image acquisition parts and the light source control part. The author mainly studies the light source control part. In the process of machine vision development, the light source...
