基于arm的fh装配生产线电气控制系统设计本科 大学论文.doc

 摘 要 本课题研究的主要目的是设计出装配生产线电气控制系统，本课题将针对装配生产线完成其加工、检测、装卸、运输等相应部分的电气控制。 随着科学技术的发展，由于传统的装配生产线无法满足柔性与生产效率相互兼顾。众所周知，只有生产品种单一、大批量、、设备专用工艺稳定并且高效的生产线才能构成一定的经济效益；反之品种多样化、设备专用性低，在加工形式相似的情况下，不断的调整工夹具，工艺不稳定，这样生产效率必然会受到影响。因此为了同时提高柔性和生产效率，使之在保证产品质量的前提下，提高生产效率，降低生产成本，最终使小批量生产能与大批量生产抗衡，柔性自动化生产系统便由此被开发出来并得到广泛应用。 而ARM嵌入式系统具有体积小、功耗低、控制功能强、扩展灵活、微型化和使用方便等优点。如果能够在电气控制系统中采用ARM，用软件实现对生产线运行的自动控制，可靠性大大提高；可实现各种复杂的控制系统，方便地增加或改变控制功能；可进行故障自动检测与报警显示，提高运行安全性和可靠性，并便于检修；用于群控调配和管理，并提高生产线运行效率。 关键字：ARM、自动生产线  ABSTRACT The main purpose of this research is to design electrical control systems assembly line , the subject will complete their respective portions of the electrical control processing, testing , handling, transportation , etc. for the assembly line. With the development of science and technology, because of the traditional assembly line can not meet each other both flexibility and productivity . As we all know , a single , high-volume , device-specific varieties and production process is stable only efficient production lines in order to constitute certain economic benefits ; contrary species diversity, device-specific low in processed form under similar circumstances , and constantly adjust workers fixture, process is unstable, so that productivity is bound to be affected. Therefore, in order to improve the flexibility and productivity at the same time , so that under the premise of ensuring product quality , increase productivity, reduce production costs, and ultimately make small batch production to compete with large , flexible automated production systems have thus been developed and widely used. The ARM embedded system with small size, low power consumption, the control function is strong, flexible expansion , miniaturization and ease of use . If you can adopt ARM in the electrical control system, automatic control software running on the production line , greatly improving the reliability ; can achieve a variety of complex control system , easy to add or change th
