基于PLC的机器视觉的应用
摘要：伴随着经济的飞速发展，自动化技术在现代建设进程中也具有重要的地位。在我国社会主义现代化建设中的许多领域中发挥了重要的作用，产生了深远的影响。自动化技术也推动着我国的工业发展，同时改变着人们的生活方式，如生活中的服务机器人代替人工做家务进入了家庭，改善了人们的生活环境。
随着时代的发展，技术水平的不断提高，机器人也被人们所接受。机器视觉是用机器来代替人的眼睛进行目标的识别、判断和测量，机器视觉技术是可以获取目标对象的图像，并对获取的图像进行处理和测量、识别的一种先进技术[5]。在自动化发展领域中，可编程控制器（PLC）发挥着重要的作用。从可编程序控制器（PLC）的产生到现在，它的控制功能和应用领域不断拓展，实现了由单体设备的简单逻辑控制到运动控制、过程控制以及集散控制等各种的复杂控制任务的进步。现在的可编程序控制器（PLC）在人机接口、处理模拟量、数字计算、工业控制网络等各个领域中发挥着重要作用，已经成为工业控制领域中的主流控制设备之一。
本课题研究的是基于可编程序控制器（PLC）的机器视觉的应用，将可编程序控制器（PLC）与机器视觉技术相结合应用，为工业生产合格的齿轮带来便捷，同时也能检测到齿轮的内径数以及齿轮的外观是否缺陷。论文通过XC系列编程软件、Touch Win编辑软件与机器视觉的X-Sight Studio软件，来进行PLC程序的控制，Touch Win编辑软件对齿轮现象的模拟运行，X-Sight Studio软件对齿轮内径、齿数的计量描述。

Abstract: along with the rapid development of economy, automation technology in the process of modern construction also has an important role. In many areas in China's socialist modernization construction play an important role, produced far-reaching influence. Automation technology also promotes the industry development of our country, while it is changing people's way of life, such as the life of a service robot in lieu of artificial do the housework in the family, improve the people's living environment.
Equipment monomer, and along with the time development, the technical level of continuous improvement, the robot also is people accept. Machine vision is to use machines to replace human eyes for target recognition, judgment and measurement, machine vision technology is to get the target image to obtain the image processing and measurement, recognition of a kind of advanced technology. The development of automation, programmable controller (PLC) plays an important role. The programmable controller (PLC) to the present, it control function and application areas continue to expand, to achieve a simple logic control to the motion control, process control and distributed control, etc. The progress of various complex control tasks. Now the programmable program controller (PLC) in the man-machine interface, analog, digital calculation, in various areas of industrial control network plays a important role, industrial control has become the mainstream in the field of control equipment.
This research is based on programmable program controller (PLC) of the machine vision application, will be series programmable controller (PLC) and machine vision technology combined with the application, for the production of qualified industrial gear convenient, but also can detect the gear diameter and gear appearance defects. The through the XC series programming software, touch win editing software and machine vision X-Sight Studio software for PLC control, touch win editing software on the phenomenon of gear simulation run, X-Sight Studio software of gear Measurement description of internal diameter and number of teeth.
Key words: programmable logic controller (PLC) machine vision technology
