Recently, the State Ministry of science and

41、 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 project.Thus, the intelligent manufacturing is arising in the world, it is

42、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 featuresWith the traditional manufacture system compares, IMS has following severa

43、l characteristics:From organization abilityIn 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 movement. Not only its flexibility displays in the movement way, but also disp

44、lays in the structural style.Aftercompleting the task, this structure dismisses voluntarily,prepares in thenext duty builds up a new kind of structure. The voluntarily organization ability is an IMS important symbol.Autonomy abilityIMS has the abilities such as collection and the understanding the e

45、nvironmentalinformation 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. IMS can act according to the environment and own work condition information to carri

46、es 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 anti jamming, auto-adapted and fault-tolerant and so on.The ability of self-study and

47、 maintenanceIMS 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, causes the knowledge library to hasten reasonably. At the sametime, it also can carry o

48、n 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.Entire manufacture system intelligent integrationWhile IMS emphasized each subsystem intellectualization, pays great attention t

49、o 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 subsystem, and integrates them in a whole, realizes the whole intellectualization.Man-machin

50、e integration intelligence systemIMS 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 man-machine integration prominent person s core status in manufacture system, simultaneously under

51、the intelligent machine coordination, well has displayed human s potential,causes between the man-machine to display one kind of equality to work together as colleagues, “ understands ” mutually, cooperates mutually relations, causes them to reveal respectively in the different level, complements ea

52、ch other. Therefore, in IMS, the high quality, the high intelligent person will play a better role, the machine intelligence and human s wisdom integration of machinery Mechatronics issue can integrate truly in together.In summary, we may view IMS as one kind of pattern, it is the collection of auto

53、mation, flexibility, integration and intellectualization in a body, and unceasingly to depth development advanced manufacture system.Virtual realityThis technology supports the realization hypothesized manufacture, also realizes one of high level man-machine integration. The man-machine union is a n

54、ew generation of intelligent contact surface, causes the available hypothesized method with intelligent performance into reality, it is a dominant character of intelligent manufacture.Future developmentArtificial intelligence technology.Since the goal of IMS is computer simulation of intelligence ac

55、tivities of manufacturing human experts, partial mental labor to replace or extension of the people, so the artificial intelligence technology has becomeone of the key technology of and artificial intelligence technology (expert system, artificial neural network, fuzzy logic) is closely related to.C

56、oncurrent 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 design.Information network technology.Information network technology is the process of manufacturing system and

57、 each link intelligent support. The information network is also the manufacturing information and knowledge flow channel.、 The virtual manufacturing technology.Virtual manufacturing technology 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
