Analysis on the Status Quo and Trend of China's Mechatronics Technology Development

In the field of mechanical engineering, due to the rapid development of microelectronics and computer technology and the mechatronics formed by the penetration of the machinery industry, the technical structure, product structure, function and composition, production methods and management systems of the machinery industry have occurred. Great changes have made industrial production from the "mechanical electrification" into the development stage characterized by "mechatronics."

China has only begun to research and apply in this area since the early 1980s. The State Council established the Mechatronics Leading Group and listed the technology as the “863 Program”. In the formulation of the "Ninth Five-Year Plan" and the 2010 Development Outline, the international development trend of mechatronics technology and its possible impact were fully considered. Many colleges and universities, research institutions and some large and medium-sized enterprises have done a lot of work on the development and application of this technology, and have not achieved certain results, but there is still a considerable gap compared with advanced countries such as Japan.

1. Mechatronics Overview Mechatronics refers to a system that combines mechanical devices with electronic design and software by introducing electronic technology into the system's main function, power function, information processing function and control function. The development of mechatronics has also become a new discipline with its own system. With the development of science and technology, it will be given new content. However, its basic characteristics can be summarized as follows: Mechatronics is a comprehensive system of mechanical technology, microelectronics, automatic control technology, computer technology, information technology, sensor measurement and control technology, power electronics technology, interface technology, information. Group technology such as transformation technology and software programming technology, according to system function objectives and optimization of organizational goals, rational allocation and layout of functional units, in the sense of multi-function, high quality, high reliability, low energy consumption to achieve specific functional value, and System engineering technology optimized for the entire system. The resulting functional system becomes a mechatronic system or a mechatronic product. Therefore, “mechatronics” covers both “technology” and “product”.

However, mechatronics technology is a comprehensive technology based on the organic integration of the above group technologies, rather than a simple combination and patchwork of mechanical technology, microelectronics technology and other new technologies. This is the fundamental difference in the concept of mechanical electrification formed by mechatronics and mechanical plus electrical. Mechanical engineering technology has developed from pure technology to mechanical electrification. It is still a traditional machine, and its main function is still to replace and amplify the physical strength. However, after the development of mechatronics, the microelectronic devices can not only replace the original functions of some mechanical components, but also give many new functions, such as automatic detection, automatic processing of information, automatic display recording, automatic adjustment and control. Automatic diagnosis and protection, etc. That is to say, mechatronics products are not only the extension of human hands and limbs, but also the senses of human beings and the eyes of the mind. The intelligent feature is the essential difference between mechatronics and mechanical electrification.

2. The development of mechatronics The development of mechatronics can be roughly divided into three stages.

The first phase before the 1960s, this phase is called the primary phase. During this period, people consciously and unconsciously used the initial results of electronic technology to improve the performance of mechanical products. Especially during the Second World War, the war stimulated the combination of mechanical products and electronic technology. These mechanical and electrical combined military technologies were converted to civilian use after the war and played a positive role in the economic recovery after the war. At that time, development and development were still in a spontaneous state as a whole. Since the development of electronic technology at that time has not yet reached a certain level, the combination of mechanical technology and electronic technology cannot be extensively and deeply developed, and the products that have been developed cannot be widely promoted.

The second stage of the 1970s and 1980s can be called the stage of vigorous development. During this period, the development of computer technology, control technology and communication technology laid the technical foundation for the development of mechatronics. The rapid development of large-scale, ultra-large-scale integrated circuits and microcomputers provides a sufficient material basis for the development of mechatronics. The characteristics of this period are: 1mechatronics was first accepted generally in Japan, and was widely recognized around the world in the late 1980s; 2 Mechatronics technology and products have been greatly developed; Great attention and support for mechatronics technology and products.

In the late 1990s, a new stage in the development of mechatronics technology towards intelligence was started, and mechatronics entered a period of in-depth development. On the one hand, optics and communication technologies have entered the electromechanical integration, micro-machining technology has also emerged in electromechanical integration, and new branches such as opto-mechatronics and micro-mechatronics have emerged; The modeling design, analysis and integration methods, the mechatronics discipline system and development trends have been thoroughly studied. At the same time, due to the tremendous progress made in the fields of artificial intelligence technology, neural network technology and optical fiber technology, it has opened up a vast world for the development of mechatronics technology. These studies will promote mechatronics to further establish a complete foundation and gradually form a complete scientific system.

3. The development trend of mechatronics Mechatronics is a cross-integration of mechanical, electronic, optical, control, computer, information and other multidisciplinary. Its development and progress depend on and promote the development and progress of related technologies. Therefore, the main development directions of mechatronics are as follows:

3.1 Intelligent intelligence is an important development direction of the development of mechatronics technology in the 21st century. The research of artificial intelligence in mechatronics builders has been paid more and more attention. The intelligence of robots and CNC machine tools is an important application. The term "intelligence" as used herein is a description of machine behavior. Based on the theory of control, it absorbs new ideas and methods such as artificial intelligence, operations research, computer science, fuzzy mathematics, psychology, physiology and chaotic dynamics. , to simulate human intelligence, so that it has the ability to judge reasoning, logical thinking, self-determination, etc., in order to obtain higher control objectives. It is true that it is impossible and unnecessary to make mechatronic products have the same intelligence as human beings. However, high-performance, high-speed microprocessors that make mechatronics products with low-level intelligence or part of the human intelligence are entirely possible and necessary.

3.2 Modular modularity is an important and arduous project. Due to the variety of mechatronic products and manufacturers, it is a very complicated but very important thing to develop and develop mechatronic product units with standard mechanical interfaces, electrical interfaces, power interfaces and environmental interfaces. For example, the development of a power unit integrating deceleration, intelligent speed regulation and motor, a control unit with functions of vision, image processing, recognition and ranging, and various mechanical devices capable of performing typical operations. In this way, new products can be quickly developed using standard units, and the scale of production can be expanded. This requires the development of standards for the matching and interface of components and units. Due to conflicts of interest, it is difficult to formulate international or domestic standards in the near future, but it can be formed by forming some large enterprises. Obviously, the benefits brought by the standardization and serialization of electrical products can be affirmed. Whether it is for enterprises that produce standard mechatronics units or enterprises that produce mechatronic products, scale will bring beautiful to mechatronics enterprises. future.

3.3 Networking In the 1990s, the outstanding achievement of computer technology was network technology. The rise and rapid development of network technology has brought tremendous changes to the daily life of science and technology, industrial production, politics, military, and education. Various networks will unite the global economy and production, and competition among enterprises will also be globalized. Once the new mechatronic products are developed, as long as they are unique in function and reliable in quality, they will soon be sold worldwide. Due to the popularity of the network, various remote control and monitoring technologies based on the network are in the ascendant, and the remotely controlled terminal devices themselves are mechatronic products. Fieldbus and LAN technology have become the trend of home appliance networking, using home network to connect various household appliances into a computer-centric computer integrated appliance system (CIAS), enabling people to share various highs at home. The convenience and happiness brought by technology. Therefore, mechatronics products are undoubtedly moving towards the direction of networking.

3.4 Miniaturization and miniaturization emerged in the late 1980s, referring to the trend of mechatronics to micro-machines and micro-fields. It is called microelectromechanical system (MEMS) in foreign countries, and it refers to mechatronic products with a geometric size of less than 1cm3, and it is developed to micron and nanometer. Micro-mechatronics products are small in size, low in energy consumption, flexible in movement, and have incomparable advantages in biomedical, military, and information fields. The bottleneck in the development of MEMS is micro-mechanical technology. The processing of MEMS products uses fine processing technology, namely ultra-precision technology, which includes lithography and etching technology.

3.5 The development of the green chemical industry has brought tremendous changes to people's lives. On the one hand, the material is rich and the life is comfortable; on the other hand, the resources are reduced and the ecological environment is seriously polluted. Therefore, people call for the protection of environmental resources and return to nature. The concept of green products came into being under such a call, and greening is the trend of the times. In the life process of design, manufacture, use and destruction, green products meet specific environmental protection and human health requirements, are harmless or less harmful to the ecological environment, and have extremely high resource utilization. The design of green mechatronic products has a great development prospect. The greening of mechatronics products mainly means that they do not pollute the ecological environment when they are used, and can be recycled after being scrapped.

3.6 One of the performance characteristics of systematic systematization is that the system architecture further adopts an open and modular bus structure. The system can be flexibly configured, arbitrarily tailored and combined, and seeks to achieve multi-subsystem coordinated control and integrated management. The second performance is the greatly enhanced communication function. In addition to RS232, there are also RS485 and DCS personality. The future of mechatronics pays more attention to the relationship between products and people. The personalization of mechatronics has two meanings. On the first floor, the ultimate use of mechatronics products is people. How to give electromechanical integration products people's intelligence, emotion and humanity become more and more important, especially for home robots, whose high-level realm is man-machine integration. The other layer is to imitate the biological mechanism and develop various electromechanical integrated flower products. In fact, many mechatronic products have been inspired by animals.

4. Conclusion In summary, the emergence of mechatronics is not isolated. It is the crystallization of many scientific and technological developments and the inevitable requirement for the development of social productive forces to a certain stage. Of course, there are still many technologies related to mechatronics, and with the development of science and technology, the trend of integration of various technologies will become more and more obvious, and the broad development prospects of mechatronics technology will become more and more bright.
