Manipulator is now used as a industrial robots in use, the control objectives often appear often in industrial automation. Industrial automation technology has gradually matured, as mature a technology line has been rapid development in industrial automation as a separate subject. Manipulator application began to filter into welding, logistics, mechanical processing, and other industries. Especially at high or very low temperatures, full of poisonous gases, high radiation case, robot in similar circumstances showed great use also brings great convenience to the staff. Precisely because of this robot to get people's attention began to be a high degree of development. Labor rates, working conditions, labor intensive aspects of promoting development. Both at home and abroad to develop the PLC (programmable logic controller) is in various special circumstances and under special conditions set for mechanical devices. Now turned on the development of the microelectronics automatic control technology and the rapid development of the trains, the success of PLC hardware software and simulation control win big and successful development, now continues to develop as a factory automation standards. Because robots are good development of the technology makes a good optimization of productive capital, and robot shows this unique advantages, such as: has good compatibility, wide availability, hardware is complete, and programming that can be mastered in a short time, so in the context of industrial PLC applications became ubiquitous. Manipulator in many developed country agriculture and industry has been applied, such as the use of mechanical harvesting large areas of farmland, repeated operations on the high-speed line that uses a robotic arm, and so on. Today, the high level of automation combined with restrictions on the manipulator development level is slightly lower than the international. The design is mainly arm welding machine by PLC Automation control. This of design let designers on in school by learn of has a must of consolidation, understand has some usually didn't opportunities awareness in world range within some leading level of knowledge has hamust awareness, hope designers can in yihou of design in the can success of using in this design in the proceeds of experience 1.2 manipulator in both at home and abroad of research profile automation mechanical arm research began Yu 20th century medium-term, after years with with computer and automation technology of development, Makes mechanical arm on the Grand stage of industrial automation and shine, gradually became an industrial evaluation standards, and its importance can be seen.

Mainly these two relatively cheap and you can meet the old-fashioned, simple (or simple) industrial equipment. So he can see them now, however these two control modes (relay and discrete electronic circuits) are these fatal flaws: (1) cannot adapt to the complex logic control, (2) only for the current project, the lack of compatibility and (3) not reforming the system with equipment improvements. Spring for the development of China's modern industrial automation technology the substantial increase in the level of industrial automation, completed the perfect relay of the computer too much. In terms of controlling the computer showed his two great advantages: (1) each of the hardware can be installed on one or more microprocessors; (2) the official designer of the software writing content control is all about. Now in several ways in the context of industrial automation can often be seen in three ways: (1) Programmable Logical Controller (referred to as IPC); (2) Distributed Control System (DCS for short), and (3) the Programmable Logical Controller (PLC for short). 2.1.2 PLC and the IPC and DCS contrast contrast 1, each of the three technologies of origins and development requirements for fast data processing makes it invented the computer. The men brought in terms of hardware there, using a high level of standardization, can use more compatibility tools, is a rich software resources, especially the need for immediacy in operational systems. So the computer can effectively control is used to control and meet its speed, on the virtual model, real-time and in computational requirements. Distributed system started with a control system for industrial automatic instrument used to control, whereas now it is successfully developed into industrial control computer used as a central collection and distribution system and transition of distributed control system in analogue handling, loop control, has begun to reflect the use of a huge advantage. Though distributed system has great advantages in loop regulation, but only as a means of continuous process control. Optimization of PLC is the corresponding relay needs was born, its main use in the work order control, early primary is replaced relay this hulking system, focused on the switch controlling the running order of functions. Marked by the microprocessor in the early 1970 of the 20th century emerged, micro-electronics technology has developed rapidly, people soon microelectronics processing technology will be used in the Programmable Logical Controller (that is

③比喻： 潭面无风镜未磨——把（潭面）比作（没有磨拭过的铜镜）。 遥望洞庭山水翠，白银盘里一青螺——把（洞庭湖）比作（白银盘）；把（君山）比作（青螺）。 6、古诗异同 同： 1、作者朝代同（都是唐朝诗人写的） 2、景物地点同（都属于江南） 3、诗词内容同（都写景，都是写景抒情的） 异： 1、体裁形式不同（前两首是诗，后一首是词） 2、诗人情感不同（前一首冷调写景言意，后两首热情颂景抒情。） 3、表现手法不同（第一首主要运用了拟人手法，第二首的比喻很巧妙，第三首对比非常强烈。） 7、古诗想象 我独自坐在敬亭山山中，这里的环境一片幽静，突然，吱吱喳喳的几只鸟儿在天空中飞过，越飞越远，直至无影无踪。天上飘浮的孤云也不愿意停留，慢慢地越飘越远。只有我看着高高的敬亭山，敬亭山也默默无语地注视着我，我们俩谁也不会觉得厌烦。谁能理解我此时寂寞的心情，只有这秀丽的敬亭山了。 秋天的一个月明星稀的夜晚，我漫步在洞庭湖边，遥望洞庭湖，银色的月光洒在水平如镜的湖面上，那柔和的月色和湖水融合在一起，整个湖面像笼罩着一层薄纱。朦胧中那君山就像一个放在白银盘里的青螺，十分惹人喜爱，我被这迷人的景色陶醉了。 春回大地的时候，百花盛开，江南的风景多么美好啊，如画的风景我久已熟悉。每当太阳从江面升起时，江边的鲜花比火红，碧绿的江水清净明澈碧如蓝草。怎能叫人不怀念江南？ Manipulator is now used as a industrial robots in use, the control objectives often appear often in industrial automation.
