Stages of vigorous development: 1970s and 1980s. During this period, the development of computer technology, control technology and communication technology laid a technical foundation for the development of mechatronics.
The stage of mechatronics technology moving towards intelligence: the end of 1990s. Electromechanical integration has entered a period of in-depth development.
Electromechanical integration technology is an application-oriented interdisciplinary technology, which is the result of organic integration and mutual penetration of mechanical technology, microelectronics technology, information technology and control technology. The digital, networked, integrated and personalized information technology revolution triggered by microelectronic technology, software technology, computer technology and communication technology not only profoundly affects the development of global science and technology, economy, society and military affairs, but also profoundly affects the development trend of electromechanical integration. Experts predict that mechatronics technology will develop in the following directions:
First, the direction of optical, mechanical and electrical integration.
General mechatronics system consists of sensing system, energy (power) system, information processing system, mechanical structure and other components. The introduction of optical technology and its inherent characteristics can effectively improve the sensor system, energy system and information processing system of electromechanical integration system.
Second, the flexibility of direction.
In the future mechatronics products, the control and execution system has enough redundancy and strong flexibility, and can cope with emergencies well, so it is designed as a "self-discipline distribution system". In this system, each subsystem works independently, serves the whole system, has its own "self-discipline" and can make different responses according to different environmental conditions. Its characteristic is that the subsystem can generate its own information and attach the given information. Under the premise, "action" can be changed. In this way, the ability (flexibility) of the system is obviously increased, and the whole system is not affected by a subsystem failure.
Third, the direction of intelligence.
In the future, the "holographic" characteristics of mechatronics products will become more and more obvious, and the level of intelligence will become higher and higher. This is mainly due to the development of fuzzy technology and information technology (especially software and chip technology).
Fourthly, the direction of bionic systematization.
The future mechatronics equipment is highly dependent on information, and the structure is often unstable when static and stable when dynamic (working). This is somewhat similar to a living creature: when the control system (brain) stops working, the creature "dies", but when the control system (brain) works, the creature is very energetic. As far as the current situation is concerned, although mechatronics products have the trend of bionic systematization, there is still a long way to go.
Fifth, the direction of miniaturization.
At present, sub-micron mechanical parts have been manufactured in the laboratory by using etching technology in the manufacturing process of semiconductor devices. When this achievement is used in practical products, there is no need to distinguish between mechanical part and controller part. At that time, machinery and electronics could completely "fuse" the body, and the executive structure, sensors, CPU, etc. could all be integrated together, and the volume was very small, forming a self-disciplined element. This miniaturization is an important development direction of mechatronics.
