基于DSP的激光标记数字控制系统设计
Design of laser marker digital control systems based on DSP
摘要
Abstract
In order to design a laser marking digital galvanometer control system, taking a digital signal processor (DSP) chip as the main processor of the digital control board, taking universal serial bus for the communication of the host computer and digital control board because of its high-speed transfer rate and hot-plug support, mark graphic data processing algorithms was completed by the high-speed DSP chip, and a complex programmable logic device(CPLD) was used to control the signal timing. For RS-485 bus can transfer differential signal, it was used to communicate between the digital galvanometer and laser. According to theoretical analysis and simulation, the rotation of digital galvanometer and laser power can be controlled with high-precision. The results show that this system can be applied for real-time, high-speed, high-precision laser marking.关键词
