Electromechanical integration technology is an application-oriented interdisciplinary technology, which is the result of the organic combination and mutual penetration of machinery, microelectronics, information and control technology. With the rapid development of mechatronics technology, mechatronics products are changing with each passing day.

First, the core technology of mechatronics

1. Mechanical technology: it is the foundation of mechatronics. The key point of mechanical technology is how to adapt to the mechatronics technology, use its high-tech to update ideas, realize the changes of structure, materials and performance, and meet the requirements of reducing weight, reducing volume, improving accuracy, improving stiffness and improving performance.

2. Computer and information technology: information exchange, access, operation, judgment and decision-making, artificial intelligence technology, expert system technology and neural network technology all belong to computer information processing technology.

3. System technology: that is, organize and apply various related technologies with the overall concept, and decompose the whole into several interrelated functional units from the overall perspective and system objectives. Interface technology is an important aspect of system technology and the guarantee to realize the organic connection of all parts of the system.

4. Automatic control technology: covering a wide range. Under the guidance of control theory, the system design, system simulation after design and field debugging are carried out. Control technologies include high-precision positioning control, speed control, adaptive control, self-diagnosis and correction, compensation, copying and retrieval.

5. Sensing detection technology: it is the sensory organ of the system and the key link to realize automatic control and adjustment. The stronger its function, the higher the degree of automation of the system.

6. Servo transmission technology: including electric, pneumatic, hydraulic and other types of transmission devices. Servo system is a device and component that converts electrical signals into mechanical actions, which has a decisive influence on the dynamic performance, control quality and function of the system.

Second, the development of mechatronics

1. The advent of CNC machine tools: It has been 50 years since 1952 America 1 CNC milling machine came out. China's CNC machine tool manufacturing industry had a high-speed development stage in 1980s, especially after 1999, the country invested a lot of technological innovation funds in national defense industry and key civilian industries, which made the CNC equipment manufacturing market prosperous.

2. Microelectronic technology development: China's integrated circuit industry started at 1965. After more than 30 years of development, it has initially formed an industrial structure including design, manufacturing and packaging.

3. Application of programmable logic controller (PLC) in industry: At the end of 1960s, the American automobile manufacturing industry developed a modular digital controller (MODICON) to replace the relay control panel. MODICON is the first PLC put into commercial production in the world. In 1970s, PLC rose and was widely used in automobile industry for the first time. Mature in the 1980 s, fully adopting microelectronics and microprocessor technology. In 1990s, PLC began its third development period. It entered the fourth stage in the late 1990s. It is characterized in that: on the premise of retaining the function of PLC, it adopts the architecture oriented to field bus network and adopts open communication interfaces, such as Ethernet and high-speed serial port; Adopt various relevant international industry standards and a series of factual standards; Therefore, with the development of computing technology, communication technology and programming technology, PLC and DCS, which were originally on different hardware platforms, tend to establish the same hardware platform and use the same operating system and the same programming system to perform different functions of DCS and PLC. This is the real integration of EIC, electricity and electricity.

4. The emergence of new technologies such as laser technology, fuzzy technology and information technology: photoelectric technology led by laser technology is the key technology for the future development of information technology. It concentrates the scientific research achievements of solid state physics, waveguide optics, materials science, micromachining and semiconductor science and technology, and becomes a new interdisciplinary subject with strong application background, which has important strategic significance for national economy, science and technology and national defense.

Third, mechatronics is becoming intelligent.

At the end of 1990s, major developed countries began a new stage of mechatronics technology moving towards intelligence. On the one hand, optics and communication technologies have entered the electromechanical integration, and micro-machining technology has also appeared in the electromechanical integration, and new branches such as optical electromechanical integration and micro-electromechanical integration have appeared; On the other hand, the modeling design, analysis and integration methods of mechatronics system, the discipline system and development trend of mechatronics are deeply studied. At the same time, due to the great progress in artificial intelligence technology, neural network technology, optical fiber technology and other fields, it has opened up a broad world for the development of electromechanical integration technology and provided a solid foundation for industrial development. The main development direction of mechatronics in the future is:

1. Intelligentization is an important development direction of mechatronics technology in the 20th century. On the basis of control theory, it absorbs new ideas and methods such as artificial intelligence, operational research, computer science, fuzzy mathematics, psychology, physiology, chaotic dynamics, etc., and simulates human intelligence, so that it has the ability of judgment and reasoning, logical thinking and independent decision-making, thus achieving higher control goals.
