摘  要

激光打標機是一種新興的機、光、電一體化設備，其應用范圍日益廣泛 。激光打標機主要用于在金屬、非金屬材料表面刻劃出字符和圖形，在許多行業(yè)中都有著廣泛的應用。然而現(xiàn)在對激光打標機的控制還不夠完善，很多產(chǎn)品都存在一些問題。
隨著處理芯片的不斷出現(xiàn)，激光打標控制器由傳統(tǒng)的單片機控制逐漸向DSP控制轉移，進而出現(xiàn)了由DSP全面代替單片機的局面。為了克服和避免現(xiàn)在已有激光打標控制系統(tǒng)出現(xiàn)的問題，本設計采用了工控機與DSP相結合的控制方式。本激光打標控制系統(tǒng)的工作原理：在工控機上運行激光打標數(shù)據(jù)生成的應用軟件,將通過104總線接口將打標數(shù)據(jù)傳送到DSP，DSP將數(shù)據(jù)進行一定的處理，如校正、插補等，做的延時功能，由于DSP內(nèi)部具有兩個定時器，可以達到激光打標機的定時要求。然后通過DAC將數(shù)字信號轉換為模擬信號，輸出控制激光打標機。
本設計實現(xiàn)了DSP5402芯片作為處理芯片對激光打標控制卡的設計，能較好的完成對激光打標的控制任務，可以克服打標速度慢和定時精度不高的缺點。本文介紹了激光打標技術產(chǎn)生的背景，現(xiàn)狀和發(fā)展；詳述了DSP5402開發(fā)環(huán)境CCS2.0的使用，DSP5402外圍電路的設計，并簡要介紹了工控機的104總線接口和DSP5402的HPI接口。在軟件設計方面，主要介紹了HPI接口的數(shù)據(jù)傳輸和DSP5402對數(shù)據(jù)的處理，簡要介紹了插補算法的原理。

Abstract

Laser Marking Machine is a new equipment that integrated of machine , light and electricity, its application scope is widespread day by day. Laser Marking Machines mainly used in metal, non-metallic materials to described characters and graphics in them surface, has the widespread application in many professions. However Laser Marking Machine control has not to be very perfect now, many products have some problems.
Along with processing chip unceasing appearance, Laser Marking controller gradually transfer from the traditional control of the microcontroller to control of DSP, Then emerged the situation that the DSP overall instead of SCM. In order to overcome and avoid the problems that have appearance in many Laser Marking system, This design uses the combination control of the IPC and DSP. The Laser Marking control system works：it runs application software on IPC to generated Laser Marking data, 104 bus interface sent the data to the DSP,DSP will do some Processing, such as correction, interpolation, and make time delay function ,due to DSP with two timers, this system can be achieved laser marking machine timing requirements., DSP the data certain processing, like the adjustment, the interpolation and so on, make certain time delay function, because the DSP interior has two timers, may achieve the laser to hit the sign machine request fixed time. Latter transforms through DA the digital signal into the simulated signal, outputs to Laser Marking Machine. Then DAC will convert digital signals to analog signals, output to control laser marking machine.
This design has realized Laser Marking control card's design with the DSP5402 chip as the processing chip to the laser, could very good completion of the laser control tasks, can overcome shortcomings, such as marking slow and low timing accuracy .This article introduced the background, the present situation and the development of Laser Marking technology; has related CCS2.0 in detail which is the development environment of DSP5402, the DSP5402 peripheral circuit's design, and introduced briefly \ 104 bus interfaces and DSP5402 HPI connection。In the software design aspect, mainly introduced the HPI interface's data transmission and the data processing in DSP5402, introduced the interpolation algorithm principle briefly.
