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 controltechnology 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.

A.多中心城市应加强各中心之间的交通联系

B.带形城市中需要完善垂直于交通主轴的道路

C.小城市适宜采用环形放射的城市空间布局结构

D.特大城市的空间布局适宜采用多中心城市结构形式

答案:C。城市发展与空间形态的形成:城市空间形态一

http://www.jsgcks.com/forum-63-1.html般分为集中型、带型、放射型、星座型、组团型和散点型六个类型。集中型城镇是最常见的基本形式,便于集中设置市政基础设施,合理有效利用土地,容易组织市内交通系统,但容易“摊大饼”式蔓延,各项城市问题难以解决;带型城市受自然条件所限或完全适应和依赖区域主要交通干线而形成;放射型城市多位于地形较平坦,对外交通便利的平原地区;星座型城市通常是一些国家首都或特大型地区中心城市,由若干相对独立的新区或卫星城镇;组团型城市多是由于较大河流或其他地形影响分隔成几个有一定规模的分区团块;散点型城市往往是资源较分散的矿业城市。

城市总体布局主要模式:分集中和分散两大类,集中式布局可划分为网格状(如洛杉矶、米尔顿凯恩斯)、环形放射状(这种形态一般不适于小城市,如北京、巴黎),分散式布局可划分为组团状、带状(线状、如深圳、兰州)、星状(指状、如哥本哈根)、环状(如新加坡、台州、荷兰兰斯塔德地区)、卫星状(如伦敦、上海)、多中心与组群城市(如底特律、洛杉矶)。

manipulator 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) theofficial 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 Manipulator is now used as a industrial robots in use, the control objectives often appear often in industrial automation.

A.各组团应根据功能基本完善、居住与工作基本平衡的原则予以组织

B.组团规模不宜太小,应配套完善的生活服务设施

C.各组团之间必须要有城市干路以上级别的道路相连

D.各组团之间应有明确的自然分隔

答案:A?。组团型城市多是由于较大河流或其他地形影响分隔成几个有一定规模的分区团块。组团式城市布局可根据用地条件灵活编制,比较好处理城市发展的近、远关系,容易接近自然,并使各项用地各得其所。关键要处理好集中与分散的“度”,既要合理分工,加强联系,又要在各个组团内形成一定的规模,使功能和性质相近的部门相对集中,分块布置。组团之间必须有便捷的交通联系。
