Review the connotation of electromechanical interface technology and the development of electromechanical integration Zheng Gang, Fei Renyuan, Zhang Huihui, Sun Shuwen (School of Mechanical Engineering and Applied Electronics, Beijing University of Technology, Beijing 100022, China) A new mechatronic system composition method. In order to further analyze and design the electromechanical integration system, the concept of electromechanical interface technology was proposed, and the classification of electromechanical interfaces was given. Finally, the influence of electromechanical interface technology on electromechanical integration is analyzed, and it is pointed out that electromechanical interface technology will inevitably promote the development of mechatronics.
1 Introduction The rapid development of science and technology has made the integration and penetration of multiple disciplines more and more important, thus forming a new research direction. Mechatronics technology is a discipline that integrates mechanical technology, servo drive technology, computer technology, automatic control technology, detection sensor technology, network communication technology, and overall system technology.
When designing mechatronics products, we must study the respective characteristics of various disciplines in various disciplines, and the physical relationships between their respective characteristic parameters, and correctly handle the requirements, relationships and coupling conditions between the characteristics of each discipline. Through the study of the intrinsic relations and coupling relations of these disciplines, we will analyze and solve specific problems in the engineering design of mechatronics product systems. The electromechanical interface technology is produced under this condition. It is a solution to how to integrate the technology of the electromechanical and related fields organically to design the optimal mechatronics product research field.
2 The relationship between the connotation of electromechanical interface technology and the composition of electromechanical integration system 21 Understanding of the composition of electromechanical integration system When studying the design of electromechanical integration products, we regard the researched object as a system, and then proceed from the overall system and study. The interrelationship of the various components of the system takes into account various factors and seeks the best solution to achieve the best results. This is an important goal of the mechatronic product system engineering design. The starting point and destination of mechatronic system design is the composition of the mechatronic system.
Due to its importance, scholars at home and abroad have conducted extensive and in-depth studies, among which are representative: fund projects: The research conditions of this project are provided by Beijing Advanced Manufacturing Laboratories to provide integrated system integration.
Sernann proposed that the mechatronics system consists of five functional modules: control function, power function, sensor detection function, operation function, and structure function. German scholars have compared mechatronic systems to people's brains, internal organs, facial features, limbs, and bodies. With the development of five mechatronics, the five block theory has been unable to meet the needs of system integration and integration.
Three-loop theory Jacob Baur et al. of the Danish University of Technology proposed mechanical, electronic, and software-related circles to represent the composition and interrelation of mechatronic systems. The meaning of electronic in Three-W Theory is ambiguous; software refers to a program that implements information processing and control, and it also fails to enable people to make scientific and explicit divisions of real systems.
The two systems Bassam AHsef of the Norwegian University of Science and Technology are the two major subsystems of the Ml Electrochemical System J divided into two systems. The physical system includes various drive devices, actuators, sensors, etc. The control system includes software and hardware. From the perspective of functional division, the two subsystems tend to be better than the former, which is conducive to the in-depth study of the control system. However, driving devices, actuators, sensors, etc. are collectively referred to as physical systems, which are too general and make system design impossible.
Zou Huijun of E-subsystem Shanghai Jiaotong University mentioned that it is also in line with the theory of hierarchical structure in natural dialectics. The basic characteristics of hierarchical structure determine the two-way causal chain in which the lower-level system can cause certain results in high-level systems. High-level systems may cause some results in low-level systems as a cause. The mechanical technology as a low-level system can only form a purely mechanical product with limited functions. When it is combined with microelectronics technology and information technology, it forms a multi-functional electromechanical integration product with electromechanical integration technology. As the mechatronics technology of high-level systems, its components: mechanical technology, microelectronic technology, information technology, etc. are not fully accepted, but they have certain limitations and influences. Only those that meet the requirements through restrictions and influences Talent into high-level systems. Mechatronic products are formed on this basis. With this understanding, we have proposed a new mechatronic system. See * In this mechatronic system model, we mainly want to explain several viewpoints: The mechatronic system consists of five parts, namely, control. Systems, power sources, drive systems, sensors and actuators.
The components of the mechatronic system are hierarchical. The control system is the control layer and controls the operation of the entire system. The power source, the drive system and the sensor drive the feedback layer and obtain commands from the control system and amplify them to drive actuator actions. The sensing actuator system can be divided into: generalized actuator subsystem, transmission subsystem, and information department. System subsystem. They complete mechanical movement and movement, information detection, information processing and control. The representation method of the trigram system is easy to understand from the perspective of functional principles, but it is also not conducive to direct use in system design.
From the above-mentioned several different understandings, it can be seen that the mechatronics system has ambiguity, complexity, and diversity, and it has become difficult for mechatronic system design. Therefore, the understanding of the composition of the mechatronics system needs to be constantly deepened and good, and the technical support of mechatronics technology has matured. The key to the design of mechatronic systems now is to master the relationships between the constituent technologies and find the optimal connection between them. This is the research content of electromechanical interface technology.
22 The Mechatronics System Group Dengn Associatedly analyzes the above-mentioned several different types of compositional structures. Starting from the relationship between the overall and part of the mechatronics system, we believe that electromechanical-fls-like support technology should be a component of its preparation technology phase. Based on mutual understanding and mutual integration, mutual assistance, mutual promotion, and enhancement of the advantages of full use of each of the relevant technologies are carried out, and strengths are avoided, so that the combination is executed in accordance with the instructions of the drive system.
Mechatronics system is an organic whole layer and layer, there is information and energy interaction in this layer. The interaction and transfer of information and energy are realized through various interfaces.
The mechatronic system can interact with people and be controlled by people. The interaction between human and mechatronic systems is achieved through man-machine interface.
It can be seen from here that the mechatronic system is an organic whole composed of multiple subsystems. The subsystems are connected through interfaces, and information and energy are exchanged. The various interfaces not only play a role in connection, but also more importantly combine the special features and advantages of the subsystems together, avoid weaknesses, and realize new functions that cannot be achieved by any subsystem. The J system is optimized. From this point of view, the performance of the system depends on the performance of the interface, and the interface performance between subsystems becomes a determinant of the performance of the integrated system. The research object of the electromechanical interface technology is the interface in the mechatronics system. Therefore, the electromechanical interface technology occupies an important position in the design of the mechatronics system and needs in-depth research.
23 Connotation of electromechanical interface technology Mechatronics system is an integrated system that integrates different functions such as machinery, electronics and information. The interface between its subsystems is extremely important. In a sense, the design of mechatronics system It is the design of the interface. But nowadays there is little research on electromechanical interface technology. Through summarizing and summarizing the mechatronics system, we have proposed the concept of electromechanical interface technology to form the following points of understanding.
(1 Connotation of myoelectric interface technology Electromechanical interface technology is an emerging technology that studies the interface between various components (subsystems) and various constituent technologies in a mechatronic system. This technology is studied to be more effective. Conduct the interaction of information energy in the system, integrate various technologies, and realize the optimal design of the mechatronics system.
(2) Functions of Mechatronics System Interface (abbreviated as Electromechanical Interface) The electromechanical interface transfers and converts information and energy, and integrates the features of the various mechatronic integration technologies. Electromechanical interfaces include hardware and software components that primarily establish connections between subsystems or between human and mechatronic systems to provide physical access to information/energy input/output, transfer, and conversion. The software mainly provides the method and process of system information exchange, transformation and adjustment. It coordinates and integrates the mechatronics integration technology to integrate and integrate the subsystems into a whole and realize new functions.
Port, power interface, smart interface and machine-electric interface 4 categories.
Human-machine interface The interface between the human and the electromechanical integration system. Through this interface, the operating status of the system can be monitored and the operation process can be controlled. That is, the human-machine interface can enable the system to work in accordance with human will. The man-machine interface is bi-directional. The hardware includes input/output devices and mainly displays, keyboards, buttons, and the like.
Power Interface The power source is connected to the drive system interface to provide the drive system with the appropriate power. According to the type of power required by the system, such as direct current, alternating current, pneumatic, and hydraulic pressure, the form of the power interface is also very different. But the power interface has a common feature that can pass larger power.
Out, the intelligent interface exists mainly in three places, the control system to the drive system, the drive system to the sensor, the sensor to the control system. The application of smart interfaces is relatively complex, but some commonalities can be derived: Smart interfaces transfer and transform various information. Change the information format according to the requirements of different technologies to enable different subsystems and different technologies to be integrated together to form The whole system. In general, smart interfaces are functional connections that software exhibits.
The interface between the machine-electrical interface actuator and the drive system and the sensor. Convert the drive signal to the signal required by the actuator, or convert the mechanical signal of the actuator to the signal required by the sensor.
3 Electromechanical Interface Technology The development of mechatronics has driven the development of mechatronics technology. When the traditional mechanical technology can not meet the increasing social needs of benefits, mechanical and electrical technology, information technology and other integrated mechanical and electrical integration technology has become the inevitable development of mechanical technology. At the beginning of electromechanical integration technology, it was only a simple combination of mechanical and electronic technologies. The way they were combined was relatively simple. With the development of mechatronics technology, mechatronic products have developed into a variety of As a complex system of technology, the interface within the corresponding system becomes more and more complex.
