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 peoples 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 didnt 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 临水临电施工方案临水临电施工方案 编制： 审核： 审批：mix carefully, 30 min at 60 c water bath for heating and cooling.

Slowly along the tubemanipulator 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 Chinas 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 9 目 录施工方案调整变更索引表2第一章：工程简介3第二章：施工现场临水临电及主要临建简介3第三章：临电设计3第四章：临水设计6第五章：临电施工技术要求及临电管理与维护6第六章：临水施工技术要求及系统维护与管理7第八章：成品保护措施8第九章：现场安全用电和消防措施8第十章：附图10施工方案调整变更索引表序号页码章节号更改内容更改人日 期更改单号备 注第一章：工程简介本工程为民航北京区域管制中心主楼，位于北京市朝阳区首都机场辅路民航200号，建筑面积11137.58平方米。主体为混凝土框架结构，独立柱基础，共二层，一层包括设备机房、UPS间、设备维修间等主要功能房间及配套房间，变配电间，柴油发电机房，空调机房，以及相关办公休息等用房；二层主要包括管制大厅、模拟培训区、飞行员培训室、附属办公用房等。第二章：施工现场临水临电及主要临建简介1. 业主在现场的东北角有一台315KVA的变压器，负责现场施工的用电。现场施工用电总柜从变压器引入。315KVA可以满足现场施工用电的要求。2. 业主在现场东侧提供水源，水源的水管为100，可以满足施工用水要求。3. 总包进场前，现场已有道路与外界相通。4. 本工程建筑红线内面积约70000m2，建筑物占地面积约7000m2。5. 现场南侧有一个市政下水口，现场内的雨水和需要排掉的施工用水将从这个下水口排入市政管线。为了保证排入市政管线的水符合要求，施工用水从积水坑中经沉淀后排出，保证排入市政管线的水不带有泥沙。6. 现场已有1000 m2的建筑物可作为施工办公用房和工人宿舍用房。第三章：临电设计表1：施工用电设备、设施配置表序号用电设备名称技术数据数量换算后的容量(kw)总容量(kw)1龙门吊2台25502电焊机JC=50% 24KVACOS=0.87 4台24.3697.443平板式震动器ZB-110-50 2.2KW2台2.24.44拖式砼泵车HBT60 75KW1台75755插入式震动器H250 5.5KW5台5.55.56打夯机2台367木工机具砂轮机1.5KW2台1.53木工园锯MJ225 4.5KW1台4.54.5木工平板刨ME503 7.5KW1台7.57.58空气压缩机12KW1台12129高压消防泵80DL*4 22KW1台222210砂浆搅拌机15KW2台7.51511镝灯6台3.52112施工照明2013办公、生活用电30KW1台3014排水潜水泵QWD-15-22 2.14台8.415钢筋加工钢筋弯曲机GWJ40 5.62台5.611.216钢筋切断机GJ40 112112217套筒挤压机6318现场临电设置：1、 现场东北侧设置一级配电柜一个。一级配电柜电缆为VV22-3*185+2*95五芯电缆，箱内设计量表。主楼及辅楼各设置一级配电柜一个。2、 现场二级配电箱，内部设置见系统图。电缆采用VV223*70+2*35或VV223*50+2*25五芯电缆。3、 现场供电采用TN-S三相五线制接零保护系统。4、 临电供电系统选用及主要线路敷设规定a) 建筑现场临时用电线路的结构形式按施工现场临时用电安全技术规范(JGJ46-88)的规定,采用电源中性点直接接地,工作零线和保护零线分开的TN-S三相五线制接零保护系统,保护零作重复接地。b) 对于公司项目安全管理手册有特殊要求消防泵用电的线路设计为：消防用电从总控开关上端引出；5、 临电供电布置（见附图：施工现场临电平面布置图）6、 电箱系统图（见附图：配电柜、箱系统图）7、 用电负荷计算及电缆截面选择a) 计算公式：i. 额定电流计算公式：I=KIP/1.73UCOS其中:KI总功率安全系数,一般取1.05-1.10;效率;P计算负荷,单位:KW;COS功率因数;ii. 总用电负荷计算公式:P=K1P1+K2P2+K3P3 (P1：动力总功率、P2：焊机总功率、P3：照明总功率)其中：K1动力需要系数 ，一般为0.4-0.6；K2焊机需要系数，一般为0.5-0.6；K3照明需要系数，一般为0.8-1.0；b) 总用电负荷计算:P=K1P1+K2P2+K3P3P=0.5285.5+0.597.4+0.971=255.37（KW）S=P/COS (S容量、P功率、COS功率因数)S=255.37/0.85=300.44(KVA)故选用315KVA变压器可满足施工用电。c) 电缆截面选择:i. 总线路电缆截面选用：总线路额定电流：I=KI.P/1.73UCOS=1.05255.371000/1.733800.90.85=566.5(A)根据临电用电安全技术规范采用VV22-3185+295铜芯电缆， ii. 消防支路：总功率为22KWI=KI.P/1.73UCOS=1.0522/1.733800.90.85=45.9(A)根据临电用电安全技术规范采用一根VV22-350+125铜芯电缆。iii.
