society after after 60 years of development the socialist society more full of life And vigor The remarkable sign is in China adhere to the basic principles of scientific socialism not lost ancestors always adhere to dialectical materialism and historical materialism as the theoretical foundation adhere to the to the realization of communism as the supreme ideal adhere to the Party of the working class as the core of leadership insist to liberate and develop productivity is the fundamental task adhere to represent the most numerous people s fundamental interests adhere to public ownership and according to work distribution is the basis of the socialist economic system adhere to the position of the people as masters of the country is the essential characteristic of the socialist democratic politics adhere to reform and improve the socialist system and institutional mechanisms and so on At the same time our country socialist And with distinct Chinese characteristics the road of socialism with Chinese characteristics the system of theories of socialism with Chinese characteristics and the socialist system with Chinese characteristics are deeply rooted in the creative practice of hundreds of millions of people s indomitable timely response to practice innovation theory calls rich heritage of both historical and cultural traditions of the Chinese nation and let the Chinese people love to see and hear the Chinese style and Chinese style comply with the requirements of the development of the times reflect the common aspiration of the people with distinct characteristics of the practice theoretical characteristics national characteristics characteristics of the times Therefore it can always maintain the vigor and vitality and always guide contemporary China along the right direction stride forward So we must always hold high the great banner of socialism with Chinese characteristics unswervingly On the other hand China s socialist society is still in primary stage which is China s construction of socialist modernization insurmountable historical stage the need for hundreds of years time China s socialist system was born in semi colonial and semi feudal society productivity level is far behind in the developed capitalist countries which determines the our country must experience a long primary stage to realize in other countries under the conditions of capitalism to achieve industrialization and production in the market socialization and modernization Today our country socialism has made remarkable tremendous To accelerate the pace of achievements but our country fundamental realities of the country is still has a large population weak thin development is not balanced China s economy has leapt to the world but the per capita gross domestic product is still ranked in the world the 90 economic sustained and rapid development but the development is not balanced coordinated can not be continued problems are still prominent the transformation of economic developmentManipulator 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 has must 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 Now original robotic arm spent most of mass production and use on the production line which is programmed robotic arm As the first generation of manipulator position control systems main features although not back several generations that can detect the external environment but can still successfully complete like welding painting delivery as well as for materials simple movements Second generation mechanical arms are equipped with sensors and manipulators have the environment there is a certain amount of sense when the mechanical arm is to use the program as a basis Difference is that the robot begand mode and deepen the reform task of industrialization urbanization and agricultural modernization but the industry is big and not strong agricultural base is still weak rural development is relatively lagging behind farmers income difficult problem is still a lot of ideological and moral construction has made important progress but some areas of moral anomie integrity deletion The National People s life has reached a comparatively well off level but the gap between urban and rural areas and residents income distribution is stillAlthough large education employment social security and other vital interests of the masses is also more part of the life of the masses remains difficult the creative vitality of society generally increased but the impact social harmony and stability of the various contradictions also many and so on These shows our country is still in and will remain so for a long time the basic national conditions of the primary stage of socialism has not changed the people s growing material and cultural needs with the contradiction between the backward social production the social principal contradiction does not change our country s international status as the largest developing country in the world has not changed I have to the problem make decisions do things to promote reform and development of the any aspect of any field Should be firmly based on the primary stage of socialism the largest practical do is not beyond the stage and is not backward reality both best effort and our capabilities the main content is what a total of eight 281 words including lead the party honest self discipline norms and the leadership

codemanipulator control mode and programmable controllers introduction 2 1 Select discussion with manipulator control 2 1 1 classification of control relays and discrete electronic circuit can control old industrial equipment but also more common 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 电 子 科 技 大 学 UNIVERSITY OF
