32、ation processing ability, efficiency and scale. At present, the advanced manufacture equipment left the information input cannot operate, flexible manufacturing system (FMS) once they are cut off the source of information will immediately cease to work. Expert thinks, the manufacturing system is dri

33、ven by the original energy into information driven, this requires a flexible manufacturing system requires not only, but also show that the intelligent, otherwise it is difficult to deal with such a large amount of workload and complex information. Secondly, the complex environment of rapidly changi

34、ng market demand and fierce competition, also called for the manufacturing system showed higher flexibility, agility and intelligence. Across the world, although the overall intelligent manufacturing was still in the stage of conceptual and experimental, but governments are included in the national

35、development plans, this push to implement. In 1992 the implementation of new technology policy and support by the President said the key to the important technical (Critical Techniloty), including information technology and new manufacturing technology, ease of intelligent manufacturing technology,

36、the U.S. government hopes the move to transform traditional industry and start a new industry. Canadas 1994 1998 development strategy plan, think the future knowledge intensive industry is driving the global economy and Canada, the basis of economic development thought is very important to developme

37、nt and application of intelligent system, and put the specific research project selection for intelligent computer, man-machine interface, mechanical sensor, the robot control system integration, the new device, the dynamic environment. Japans in 1989, intelligent manufacturing system is proposed an

39、tc. Research of information technology in the European Union ESPRIT project, the project is funded by the market potential of information technology. 1994 and the start of the new R&D project, select the 39 core technologies, of which three (information technology, molecular biology and advanced man

40、ufacturing technology) are highlights the intelligent manufacturing location. China at the end of the 80s will intelligent simulation the main issue in the national science and technology development planning, understanding has made a number of achievements in the expert system, pattern recognition,

41、 robotics, Chinese machine. Recently, the State Ministry of science and technology put forward formally industrial intelligent engineering, as an important part of the innovation ability of technology innovation project construction, intelligent manufacturing will be an important content of the proj

42、ect.Thus, the intelligent manufacturing is arising in the world, it is the development of manufacturing technology, especially the inevitable manufacturing development of information technology, is the result of the development of automation and integration technology in depth.Integrated featuresWit

43、h the traditional manufacture system compares, IMS has following several characteristics:(1)From organization ability In the IMS, each kind of composition unit can according to the work duty need, voluntarily build up one kind of ultra flexible best structure, and defers to the most superior way mov

44、ement. Not only its flexibility displays in the movement way, but also displays in the structural style. After completing the task, this structure dismisses voluntarily, prepares in the next duty builds up a new kind of structure. The voluntarily organization ability is an IMS important symbol.(2)Au

45、tonomy ability IMS has the abilities such as collection and the understanding the environmental information and own information, and carries on the analysis to judge and to plan own behavior ability. The powerful knowledge library and based on the knowledge model is the autonomy ability foundation.

46、IMS can act according to the environment and own work condition information to carries on the monitor and processing, and according to the processing finally self-adjusting control strategy, uses the best movement plan. This kind of autonomy ability causes the entire manufacture system to have the a

47、nti jamming, auto-adapted and fault-tolerant and so on.(3)The ability of self-study and maintenance IMS can take the original expert knowledge as the foundation, in reality carries on the study unceasingly, the perfect system knowledge library, and deletes the unsuitable knowledge in the storehouse,

48、 causes the knowledge library to hasten reasonably. At the same time, it also can carry on the self-diagnosis, the elimination and repairing to the system failure. The kind of character enables IMS to optimize and to adapt to each kind of complex circumstances.(4)Entire manufacture system intelligen

49、t integration While IMS emphasized each subsystem intellectualization, pays great attention to the entire manufacture system the intelligent integration. This is the basic difference between IMS and “the intellectualized isolated” which specially applied in the manufacture process. IMS contains each

50、 subsystem, and integrates them in a whole, realizes the whole intellectualization.(5)Man-machine integration intelligence system IMS is not a pure the artificial intelligence the system, but is the man-machine integration intelligence system, is one kind of mix intelligence. On the one hand, the ma

51、n-machine integration prominent persons core status in manufacture system, simultaneously under the intelligent machine coordination, well has displayed humans potential, causes between the man-machine to display one kind of equality to work together as colleagues,“understands” mutually, cooperates

52、mutually relations, causes them to reveal respectively in the different level, complements each other. Therefore, in IMS, the high quality, the high intelligent person will play a better role, the machine intelligence and humans wisdom integration of machinery Mechatronics issue can integrate truly

53、in together.In summary, we may view IMS as one kind of pattern, it is the collection of automation, flexibility, integration and intellectualization in a body, and unceasingly to depth development advanced manufacture system.(6)Virtual reality This technology supports the realization hypothesized ma

54、nufacture, also realizes one of high level man-machine integration. The man-machine union is a new generation of intelligent contact surface, causes the available hypothesized method with intelligent performance into reality, it is a dominant character of intelligent manufacture.Future development1、

55、Artificial intelligence technology. Since the goal of IMS is computer simulation of intelligence activities of manufacturing human experts, partial mental labor to replace or extension of the people, so the artificial intelligence technology has become one of the key technology of IMS.IMS and artifi

56、cial intelligence technology (expert system, artificial neural network, fuzzy logic) is closely related to. 2、Concurrent engineering. In view of the manufacturing, concurrent engineering is an important technical method, used in IMS, will reduce the repetition blindness and the design of the product

57、 design.3、Information network technology. Information network technology is the process of manufacturing system and each link intelligent support. The information network is also the manufacturing information and knowledge flow channel. 4、The virtual manufacturing technology. Virtual manufacturing t

58、echnology can simulate the entire life cycle of product in the product design stage, thus the more effective, more economical, more flexible organization of production, the product development cycle is short, the product cost is the lowest, the optimal product quality, production efficiency is the highest assurance. At the same time, the virtual manufacturing technology is the prerequisite for the engi
