Mechanical and electrical employment prospects?

Employment prospect of mechatronics specialty

Relevant research reports show that the term "mechatronics" was first put forward by Japan. In the early 1980s, Nagoya University in Japan opened the major of mechatronics for the first time, and now it has been renamed as "Mechanical and Electronic Engineering". In higher vocational colleges, the name of mechatronics is still in use. Electromechanical integration is the product of the intersection and integration of precision machinery, electronic technology (including power electronics) and computer technology. It is a high-tech and one of the fastest developing technologies at present. It is the main component of advanced manufacturing technology. Its development has promoted the rapid upgrade of current manufacturing technology, and it is a big step for products to be high, precise and fast. Labor productivity has increased rapidly. With China gradually becoming a manufacturing base in the world, traditional enterprises are facing large-scale technological transformation and equipment renewal, and China urgently needs a large number of advanced manufacturing technology professionals. Therefore, graduates of this major have good employment prospects and high salaries. Graduates are mainly engaged in mechanical and electrical engineering, maintenance of common electrical appliances, installation and debugging, technical management and other work in various administrative, enterprises and institutions.

What is the employment prospect of mechatronics major? Market research shows that mechatronics major is a wide-caliber major with a wide range of applications. During school, students should not only learn various theoretical knowledge such as machinery, electrical and electronic, computer technology, control technology, detection and sensing, but also participate in various skills training and national vocational qualification examination, which fully embodies the characteristics of attaching importance to skills training. After graduation, students mainly face enterprises and companies in the Pearl River Delta, engaged in processing and manufacturing, household appliances production and after-sales service. CNC machine tool equipment maintenance, property automation management system, mechanical and electrical product design, production, transformation, technical support, and mechanical and electrical equipment installation, debugging, maintenance, sales, management, etc. [2]

With the development of easy-going economy and the progress of science and technology, more and more products are intelligent, automated and networked. In addition to mechanical shelling, these products need circuit control. The electrical part is no longer a simple switching circuit, but a large-scale integrated circuit. Intelligent components such as single chip microcomputer, sensor and programmable controller are combined with the mechanical part of the equipment. Simple machinery and simple electronics can no longer meet the needs of industry development, and the subject of mechatronics has gradually emerged. Mechatronics first appeared in the supplement of Japanese magazine Mechanical Design of 197 1, and has gradually matured. Electromechanical integration technology includes six parts, namely: first, mechanical technology. Mechanical technology is the foundation of mechatronics. The key point of mechanical technology is how to adapt to mechatronics technology, use other high-tech to update concepts, realize changes in structure, materials and performance, and meet the requirements of reducing weight, reducing volume, improving accuracy, improving stiffness and improving performance. In the manufacturing process of mechatronics system, the classical mechanical theory and technology should use computer-aided technology, artificial intelligence and expert system to form a new generation of mechanical manufacturing technology. Second, computers and information technology. Among them, 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. Third, system technology. System technology is to organize and apply various related technologies with the concept of the whole, and decompose the whole into several interrelated functional units from the perspective of the whole and the system goal. Interface technology is an important aspect of system technology and the guarantee to realize the organic connection of all parts of the system. Fourth, automatic control technology. It covers 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. Fifth, sensing detection technology. Sensing detection technology 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. Modern engineering requires that sensors can obtain information quickly and accurately, and can withstand the test of harsh environment, which is the guarantee for the electromechanical integration system to reach a high level. Sixth, servo drive technology. Servo system includes electric, pneumatic, hydraulic and other types of transmission devices, which are devices and components to convert electrical signals into mechanical actions and have a decisive impact on the dynamic performance, control quality and function of the system. [1] The electromechanical integration system is mainly composed of five parts: mechanical body, detection and sensing part, electronic control unit, actuator and power supply. Mechanical body includes frame, mechanical connection, mechanical transmission, etc. It is the foundation of mechatronics, and plays the role of supporting other functional units in the system and transmitting movement and power. Compared with pure mechanical products, the technical performance and function of mechatronics system have been improved, which requires the mechanical body to adapt to it in terms of mechanical structure, materials, processing technology and geometric dimensions, and has the characteristics of high efficiency, multifunction, reliability, energy saving, small volume, light weight and beauty. The detection and sensing part includes various sensors and their signal detection circuits, which are used to detect the parameter changes related to the external environment during the working process of the mechatronics system and transmit the information to the electronic control unit, which sends corresponding control to the actuator according to the detected information; The electronic control unit, also known as ECU(Electrical Control Unit), is the core of the mechatronics system. It is responsible for centralizing, storing, calculating and analyzing the detection signals from various sensors and external input commands, and issuing corresponding instructions according to the information processing results to a certain extent and rhythm, so as to control the whole system to carry out purposefully. The function of the actuator is to drive the movement of mechanical parts according to the instructions of the electronic control unit. The actuator is a moving part, usually driven by electricity, air pressure and hydraulic pressure. Power supply is the energy supply part of mechatronics products, and its function is to provide energy and power to the mechanical system according to the system control requirements, so that the system can operate normally. The ways to provide energy include electric energy, pneumatic energy and hydraulic energy, in which electric energy is the main energy. [2] Machinery, as a tool to reduce human labor intensity, has been developing and progressing continuously since its appearance. Modularization, networking, intelligence, automation, systematization and greening have become the development direction of machinery. In the next few centuries, nothing can replace machines. In other words, this industry still has a long way to go, and its proportion in people's consumption will continue to increase. The competition in this industry will become more and more fierce. Mechanical and electrical integration products can only be made into excellent mechanical and electrical integration products by continuous innovation and perfect combination of software and hardware.
