Electromechanical thesis

Mechatronics technology development and trends since the advent of electronic technology, electronic technology and mechanical technology has begun, only the emergence of semiconductor integrated circuits, especially the emergence of microprocessors as a representative of the large-scale integrated circuits, "mechatronics" technology, after a significant progress, attracted widespread attention. (A) the development of mechatronics "1. The introduction of CNC machine tools, wrote the" mechatronics "history of the first page; 2. Microelectronics technology for" mechatronics "" to bring vitality; 3. Programmable controllers, "power electronics" and other developments for the" mechatronics "to provide a strong foundation; 4. Laser technology, fuzzy technology, information technology, and other new technologies to make" mechatronics "jump to a new level. New stage. (B) mechatronics" development trend 1. optical mechatronics. General mechatronics system is composed of sensing system, energy system, information processing system, mechanical structure and other components. Therefore, the introduction of optical technology, the realization of the inherent advantages of optical technology is to effectively improve the mechatronics system sensing system, energy (power) system and information processing system. Optical mechatronics is an important trend in the development of electromechanical products.2. Self-regulating distribution systemization - flexibility. Future mechatronics products, control and execution systems have enough "redundancy", have a strong "flexibility", can better cope with emergencies, is designed as a "self-regulating distribution system The system is designed as a "self-regulating distribution system". In a self-regulating distribution system, each subsystem works independently of each other, and the subsystems serve the total system, while having their own "self-regulation", and can react differently according to different environmental conditions. It is characterized by the fact that the subsystems can generate their own information and add to the given information, and the specific "actions" can be changed under the general premise. In this way, not only significantly increase the adaptability of the system (flexibility), but also not due to the failure of a subsystem and affect the whole system. 3. holographic systemization - intelligent. The future of mechatronics products "holographic" features more and more obvious, the level of intelligence is higher and higher. This is mainly due to fuzzy technology, information technology (especially software and chip technology) development. In addition, the hierarchical structure of the system, but also change the simple "from top to bottom" situation for complex, more redundant two-way links. 4. "Biological a software" - biomimetic system. Future mechatronic devices are highly information-dependent and tend to be structurally unstable when "static" but stable when dynamic (working). This is somewhat analogous to living organisms: when the control system (brain) stops working, the organism "dies", whereas when the control system (brain) is working, the organism is very much alive. Bionics research field has found some of the organism's excellent institutions for mechatronics products to provide a new type of body, but how to make these new types of body with a living "life" is still to be studied in depth. This research field is called "biology - software" or "biology - systems", and biological characteristics are Hardware (body) - software (brain) one, inseparable. It seems that mechatronics products, although there is a tendency to the development of biological systems, but there is a long way to go. 5. micro-mechatronics - miniaturization. At present, the use of semiconductor device manufacturing process in the etching technology, in the laboratory has produced sub-micron mechanical components. When this result is used in real products, there is no need to distinguish between the mechanical part and the controller. Mechanical and electronic can be completely "fusion", the body, actuators, sensors, CPU, etc. can be integrated together, the volume is very small, and form a kind of self-regulating components. This micro-mechanics is an important development direction of mechatronics. Second, the typical mechatronics products mechatronics products are divided into two categories of systems (machine) and basic elements and components. Typical mechatronics systems are: CNC machine tools, robots, automotive electronic products, intelligent instrumentation, electronic typesetting and printing systems, CAD / CAM systems. Typical mechatronics components: power electronics and devices, programmable controllers, fuzzy controllers, micro-motors, sensors, special integrated circuits, servo mechanisms and so on. These typical mechatronics products, the current state of technology, development trends, market outlook analysis from the omitted. Third, China's development of "mechatronics" facing the situation and tasks of mechatronics work mainly includes two levels: one is the use of microelectronics technology to transform traditional industries, the purpose of which is to save energy, save materials, improve efficiency, improve product quality, the traditional industrial technology to improve the progress of a step; the second is the development of automation, digitalization, intellectualized electromechanical products and promote product upgrading. (A) China's "mechatronics" work facing the situation 1. China's microelectronics technology to transform traditional industries, the workload is large and wide, difficult 2. China's mechatronics technology to accelerate product upgrading to increase market share of the call is high, there is pressure. 3 China's mechatronics products to replace the low technological content and added value, energy-consuming, water-consuming, consumptive and energy-saving products, and the need for the development of new products. , the responsibility of high energy consumption, water consumption, consumables, pollution and nuisance products is heavy and meaningful. In China's industrial system, energy consumption, water consumption, serious environmental pollution of enterprises still account for a considerable proportion. In recent years China's industrial structure, product structure, although several adjustments, but for a variety of reasons, the results have not been obvious enough. This certainly has the higher leadership departments of the government out of the problem, there are enterprises "difficult to leave the homeland," "die in the old industry," the problem, but it is undeniable that there is not optimized out of the ideal industry, preferably not out of the preferred product problems. The best answer has long been in front of these enterprises, which is the development of mechatronics, development and production of mechatronics products. Mechatronics products with strong functions, good performance, high quality, low cost, and flexibility, according to market needs and user feedback when the product structure and production process to make the necessary adjustments, reforms, without having to change equipment. This is an important way out to solve the many varieties of electromechanical products, less mass production. At the same time, the traditional machinery industry can be injected into the fresh blood, bring new vitality, the mechanical production from the heavy physical labor freed from civilized production. In addition, from the point of view of market demand, due to China's research and development of mechatronics products, the history is not long, the gap is large, many of the product varieties, quantities, grades, quality can not meet the demand for imports every year are relatively large, so there is an urgent need for development. (B) China's "mechatronics" task in China's mechatronics task can be summarized in two sentences: one sentence is a wide range of in-depth use of mechatronics technology to transform traditional industries; the other sentence is to develop mechatronics products with great fanfare, to promote the upgrading of electromechanical products. The overall purpose is to promote the formation of mechatronics industry, for China's industrial structure and product structure adjustment to contribute. In short, mechatronics technology is not only to revitalize the traditional electromechanical industry of fresh blood and source of power, but also to open the door of China's electromechanical industry product structure, industrial structure adjustment key. Fourth, China's development of "mechatronics" countermeasures (a) to strengthen the overall arrangement and coordination of development plans At present, China is engaged in "mechatronics" research and development and production of many units. Each has its own set of development strategies. Each unit's plan due to their respective footholds, focusing on the limitations, it is inevitable to consider only local interests, the competent departments of the relevant plans and planning, there is insufficient unity of consideration, not enough co-ordination of the problem, while the lack of a comprehensive view of the overall situation of the development of authoritative plans and strategic planning. Therefore, it is recommended that the competent authorities to task the relevant units in conducting in-depth investigation and research, based on scientific analysis, to develop a comprehensive "mechatronics" research, development, production plans and planning, to avoid duplication of development, production collision! (B) strengthen industry management, play the role of the "Association" At present, China's "mechatronics" hotter, and according to the current industry division methods and management system, "government out of many doors" is hard to Do. Therefore, it is necessary for our country to clarify a "mechatronics" industry management organization, according to the spirit of the current national political system reform and economic system reform, as well as the characteristics of the mechatronics industry, we suggest that, as soon as possible to strengthen the construction of the Beijing Mechatronics Association, to give its industry management functions. "The association should further expand the representative level and coverage of the governing body, the council, and strengthen the construction of the office and the secretariat; it should organize the "industry" through its smart and competent offices and economic entities. "Development plan, strategic planning of the preparation; guide the adjustment of the layout of the industry layout, the development of breakthroughs in the selection of the pilot project to grasp the key projects and projects related to the issuance of bids, tenders ...... (c) optimize the development of the environment, increase support Optimization of the development of the environment refers to the masses through the propaganda, resulting in A society up and down, inside and outside the enterprise are attached importance to, support the development of "electromechanical integration" atmosphere, such as as soon as possible for foreign investment in our country to develop "electromechanical integration" industry to provide convenience; as far as possible for the development and production of electromechanical integration of high-tech products for the establishment of the enterprise Green light; try to develop and produce mechatronics products for the deployment of resource elements. Increase support, in the technology policy, to strictly limit the power consumption, water consumption, high consumption of traditional products development, not the use of mechatronics technology to limit the mandatory elimination of outdated products; vigorously advocate the use of mechatronics technology for the transformation of traditional industries, on the mechatronics technology for the traditional industries to reform, the technology development and application of the project priority projects, priority support, in the development of technology, Application of the contribution of unit leaders, scientific and technological personnel for recognition and reward. (D) highlight the focus of development, taking into account the "two levels" of mechatronics industry covering a very wide range, and our financial, human and material resources are limited, so we grasp the development of mechatronics industry can not be all-encompassing, flat, and should be clear, bold trade-offs, and some do, some do not do. To pay attention to the work on two levels. The first level is the "surface" of the work, that is, the use of electronic information technology to transform traditional industries, in the traditional mechanical and electrical equipment implanted or grafted on the microelectronic (computer) devices, so that the "mechanical" and "electronic" technology at a shallow level. The second level is the "improvement" of the traditional industries. The second level is to "improve" the work, that is, at the beginning of the design of new products, the "mechanical" and "electronic" unified for consideration, so that "mechanical" and "electronic" technology at a shallow level. Mechanical" and "electronic" inextricably linked, the depth of the combination of production out of the new product at least is to achieve mechatronics.
