1 preface
The performance of mechatronics products depends largely on the interface performance, that is, the interface performance between components and subsystems is the decisive factor for the performance of integrated systems. Therefore, electromechanical interface technology is a research field to solve how to organically integrate electromechanical and related fields to design the best electromechanical integrated products.
Design of mechatronics system
Mechatronics is an advanced technology based on modern high-tech groups such as machinery, electronics, computers, automatic control, sensing and testing. Mechatronics products are composed of mechanical subsystem and microelectronic subsystem, which are composed of several components respectively. To form a complete system, it is necessary to transfer and exchange materials, energy and information smoothly between various elements and subsystems of the system. In other words, the interface between each component and subsystem must have certain contact conditions, which is the interface of electromechanical integration system.
In the early electromechanical integration system, the design of mechanical part is the center of system design. Electric energy is only used to drive and power the system. Although the transmission structure of mechanical system can be simplified by using the variable speed function of DC motor, program automation is still the main goal of system control design because the stroke of moving parts can not be controlled. The motion, speed and direction of the servo motor can be controlled, and the independent/linkage control of the position and trajectory of the moving parts makes flexible automation possible. Driving motor is no longer the starting point of mechanical motion chain, but the interface connecting mechanical motion, power and control. Design of mechatronics system from? Pure? Mechanical design extends to the field of control. Computer, digital circuit, sensor and automatic control theory have become an indispensable knowledge base for system designers. Information technology and software design have become important tools to express system design ideas and coordinate automation work.
Electromechanical integration technology is a process of continuous development and perfection. Product precision and production efficiency require the electromechanical integration system to continuously improve the servo drive performance and develop the control algorithm. The servo drive with excellent performance not only expands the function of the mechanical system and simplifies the traditional mechanism, but also requires the mechanical system to have reasonable inertia and better system dynamic performance. The on-line monitoring of sensors ensures the safe and reliable operation of the system, and the feedback information ensures the realization of advanced control theory and product quality requirements through closed loop. The close intersection of machinery, electricity and information makes the interaction and influence of various parts in the mechatronics system an important content that must be comprehensively considered in the design. The early mechatronics design mainly focused on the composition and structure of the system. With the enrichment of design practice and the maturity of design theory, electromechanical interface technology, as the core of electromechanical integration design, has attracted more and more attention from experts and scholars.
3 the connotation of electromechanical interface technology
Mechatronics system is a comprehensive system integrating technologies with different functions such as machinery, electronics and information, and the interface between its subsystems is extremely important. In a sense, the design of mechatronics system is the design of interface. However, there is little research on electromechanical interface technology now. Through the summary and induction of electromechanical integration system, we put forward the concept of electromechanical interface technology and formed the following understanding.
3. 1 the connotation of electromechanical interface technology
Electromechanical interface technology is a new technology, which studies the interface between each component (subsystem) and each component technology in electromechanical integration system. The purpose of studying this technology is to interact the information energy in the system more effectively, integrate various technologies and realize the optimal design of electromechanical integration system.
3.2 Functions of Electromechanical Integration System Interface (hereinafter referred to as Electromechanical Interface)
The electromechanical interface transmits and converts information and energy, which integrates the characteristics of each component technology of mechatronics. Electromechanical interface includes hardware and software. Hardware mainly establishes the connection between subsystems or between human and mechatronics system, and provides physical channels for input/output, transmission and conversion of information and energy. The software mainly provides the methods and processes of system information interaction, conversion and adjustment, and coordinates and synthesizes the technology of mechatronics, so that each subsystem can be integrated into a whole and realize new functions.
3.3 Classification of electromechanical interfaces
Electromechanical interface includes man-machine interface, power interface, intelligent interface and electromechanical interface.
3.3. 1 man-machine interface
The interface between man and mechatronics system can monitor the running state of the system and control its running process, that is, the system can work according to man's will through man-machine interface. The man-machine interface is bidirectional, and the hardware includes input/output devices, mainly including display screen, keyboard and buttons.
power source
The power supply is connected to the interface of the drive system to provide the corresponding power supply for the drive system. According to the different types of power required by the system, such as DC, AC, pneumatic, hydraulic, etc. The form of power interface is also very different. But the power interface has a * * * feature, which can pass more power.
Intelligent interface
Intelligent interface mainly exists in three places, from control system to drive system, from drive system to sensor, and from sensor to control system. The application of intelligent interface is relatively complicated, but we can get some characteristics of it: intelligent interface transmits and converts all kinds of information, and changes the information form according to the requirements of different technologies, so that different subsystems and different technologies can be integrated together to form a complete system. Usually, an intelligent interface is a functional connection displayed by software.
Mechanical-electrical interface
Interface between actuator, drive system and sensor. Convert the driving signal into the signal required by the actuator, or convert the mechanical signal of the actuator into the signal required by the sensor.
4 the impact of electromechanical interface technology on the development of mechatronics
Social demand promotes the development of mechatronics technology. When the traditional mechanical technology can not meet the growing social needs, the mechatronics technology formed by the combination of mechanical technology, electronic technology and information technology has become the inevitable development of mechanical technology. In the early days, mechatronics technology was only a simple combination of mechanical technology and electronic technology, and the way of combining them-interface was also relatively simple. With the development of mechatronics technology, mechatronics products have developed into a complex system integrating various technologies, and the internal interfaces of the corresponding systems have become more and more complicated.
The research on each component technology of mechatronics technology has been deepened and matured, and people also realize that simple development and research on each component technology can not guarantee the optimization of mechatronics system. We believe that we should study not only the theory of system design, but also the theory of system integration and fusion. However, due to the complexity of the mechatronics system, it is difficult for these two theories to study the mechatronics system in detail and can only stay at the theoretical level. Electromechanical interface technology provides them with an effective way to study the system, and applies the theory of system design, integration and fusion to practical design.
Now, mechatronics is developing in the direction of intelligence, modularization and networking. Intelligentization inevitably requires that all parts of the system be more closely combined, and information transmission and feedback are more rapid and accurate. Modularization is bound to put forward higher requirements for interfaces, which must ensure the transmission of system information and energy and the integration of technologies while maintaining consistency. Networking requires the interface of the system to have network functions, including field network, local area network and Internet functions. Judging from the requirements of the development direction of mechatronics for electromechanical interface technology, the research and development of electromechanical interface technology has become inevitable, and the research and development of electromechanical interface technology will inevitably promote the development of mechatronics technology.
5 conclusion
The mechatronics system is developed by the continuous integration of various new technologies and new knowledge into the mechanical system. Therefore, the complexity and multidisciplinary nature of mechatronics technology developed from mechanical technology determines that the research focus of this technology is the integration and innovation of various technologies in mechanical technology. Electromechanical interface technology is to study the interface problem in electromechanical integration system, which makes the transmission and conversion of information and energy in the system smoother, and makes all parts of the system organically combined to form a complete system. Electromechanical interface technology is developed on the basis of electromechanical integration technology, and becomes more and more important with the development of electromechanical integration technology. At the same time, the research of electromechanical interface technology will inevitably promote the development of electromechanical integration and the development of electromechanical integration system theory.
