Project safety objective management network diagram 2-4 Project Department safety target decomposition (reference) Ann 2-4-1 for implement "security first, prevention" approach, implemented "who tube who is responsible for" principles, to caught focus parts (dangerous points, and source), and except hidden, and anti-accident for total target, effective implement safety target accountability, closely control and prevention "three big hurt" of occurred, developed security target decomposition following: a, and project manager project safety first responsibility people. Target: implementation of national security policies and laws and regulations for project management and construction personnel security awareness,regulations. The revised regulations from the original 3 series, Chapter 15, 178, more than 24000 words reduced to 3, Chapter 11, 133, 17000 words. For example, before theWith criminal law coincidence of corruption and bribery, dereliction of duty dereliction of duty and other content, not a separate provisions in the party. Special supervisors of the Commission, Ma, vice president of China University of politics and law said, current disciplinary punishment regulation of December 2003 promulgated and implemented, but with the development of the situation, have been unable to fully meet the strictly new needs. The biggest problem is discipline law, of which nearly half of the content and the criminal law, the law on administrative penalties for public security, such as repeated, in fact, it is difficult to use, but also a waste of administrative costs, even in very few cases will appear to Ji generation method, pre empt. The revised implementation of the strictly, the party must manage the party, strengthening discipline check , for the party to "overweight", before the law for the party delineated discipline bottom line, from wrong grabbed, not to become Dang Jiyan Yu Guofa empty. The amendment Ordinance: to strengthen the role of the negative list, the provisions of the original Ordinance 10 categories of misconduct combing the integration and scientific revision for six categories: violation of political discipline, discipline, honesty and discipline, discipline of the masses, work discipline and discipline, the party constitution about discipline specific requirements, and sorting in the provisions of chapters in accordance with the similar similar and severely to the principle of National School of administration Professor Wang Yukai says, in the past, in violation of the party constitution, damage the authority of Party Constitution of misconduct lack seriously In terms of responsibility, to amend the legislation integration clear the members of the "negative list, of Party members and cadres prohibited behavior of the scope of the facts were adjusted, refining the content, operation and not only told party members and cadres, what kind of behavior is not, also put forward clear basis for punishment, disciplinary action is no longer available drilling. The Central Party School professor Xin Ming said that the old regulations is a prominent issue is what are the tube, but some problems did not manage well. For example, political discipline, political rules previously difficult to grasp, there is a gray area, the amendment clarifies lists can" condemnation ", the discipline can not luck. Amendment: strict since the eighteen Political discipline and rules, organization and discipline, the implementation of provisions of the eight, against the "four winds" strictly administering the practice results of the institutionalized, normalized. Regulations clearly increased the some disciplinary terms, such as honesty and discipline increased trading rights, using in position or positions of influence as relatives and close to profit etc.; breach of discipline of the masses in the new against the interests of the masses,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 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
