【摘要】：传统的图形输出设备如打印机,绘图仪等一般是在纸质材料中完成图像的输出,而对于特殊的加工工件以及加工条件则无法实现图像的输出。摇臂式雕刻机是为了满足特定的要求,针对石板,木板以及铁板等难以加工的工件而设计制造的一种特殊的图形输出设备。在这些特定条件下,摇臂式雕刻机必将展现出其特有的优越性。本文主要介绍了摇臂式雕刻机工作前的图像前处理,总体结构设计以及摇臂式雕刻机的嵌入式控制系统。考虑到加工工件的特殊性以及摇臂式雕刻机本身的分辨率不高等因素,必须在加工工件前对图像进行处理。本文首先介绍了图像处理的相关概念以及数字图像的特点,从数字图像本身的特点阐述了摇臂式雕刻机打印图像的可行性,摇臂式雕刻机所能输出的图像为灰度等级为八的灰度图像,而不是单一的黑白图像,因此需要对图像进行处理以最终生成符合雕刻机要求的八级灰度图像,将处理后的图片代码送入摇臂式雕刻机控制系统,在嵌入式处理器S3C44BOX的控制下便可完成图像的输出。与传统雕刻机相比,摇臂式雕刻机在结构和运动方式上也有其特点,本文详细介绍了摇臂式雕刻机的总体结构及其采用极坐标的运动方式。最后,介绍了以嵌入式处理器S3C44BOX为核心的控制系统,并对其接口电路进行了分析。由于摇臂式雕刻机本身结构的特点以及采用了嵌入式控制系统使其与传统雕刻机相比更加小型化,功能也更加完善。
[Abstract]:Traditional graphic output devices, such as printers and plotters, usually complete the output of images in paper-based materials, but the output of images can not be realized for special machining parts and processing conditions. Rocker-arm engraving machine is a kind of special graphic output equipment designed and manufactured for hard-to-process workpieces such as stone plank and iron plate in order to meet the specific requirements. Under these special conditions, the rocker-arm engraving machine will show its unique superiority. This paper mainly introduces the image pre-processing, the overall structure design and the embedded control system of the rocker-arm engraving machine. Considering the particularity of machining workpiece and the low resolution of rocker-arm engraving machine, it is necessary to process the image before machining the workpiece. In this paper, the concept of image processing and the characteristics of digital image are introduced firstly, and the feasibility of printing image by rocker-arm engraving machine is expounded from the characteristics of digital image itself. The image that the rocker-arm engraving machine can output is a grayscale image with a grayscale level of eight, rather than a single black-and-white image, so the image needs to be processed to finally produce an eight-level grayscale image that meets the requirements of the engraving machine. The processed image code is fed into the control system of rocker-arm engraving machine, and the image output can be completed under the control of embedded processor S3C44BOX. Compared with the traditional engraving machine, the rocker-arm engraving machine also has its characteristics in structure and motion mode. This paper introduces the overall structure of the rocker-arm engraving machine and its motion mode using polar coordinates in detail. Finally, the control system based on embedded processor S3C44BOX is introduced, and its interface circuit is analyzed. Because of the characteristics of the structure of the rocker arm engraving machine and the embedded control system, it is more miniaturized and more perfect than the traditional engraving machine.
