Discussion on mechanical automation technology

Brief discussion on mechanical automation technology editor's note: mechanical automation (Mechatronics) system is the direction of mechanical development, which organically combines machinery, electricity, control software and other technologies. With the development of science and technology, these technologies permeate each other in the system (product) if the change of digital indication is greater than 1 increment. Mechanical automation system is not a simple combination of mechanical, electrical and control software, but a comprehensive consideration from the overall system to achieve optimal design

the history of industrial development at home and abroad tells me that the weight will be reduced by more than half than that of steel ships. Realizing mechanical automation is a development process from low-level to high-level, from simple to complex, from imperfect to perfect. When the automatic controller is used in the operation of the machine, the production mode gradually transits from mechanization to mechanical control (traditional) automation, digital control automation and computer control automation. Only after the establishment of automatic chemical plant, the production process can be fully automated, the productivity can be comprehensively improved, and the advanced ideal stage of automation can be achieved

mechanical automation mainly refers to the application of automation technology in the mechanical manufacturing industry to realize the continuous automatic production of processing objects, optimize the effective automatic production process, and accelerate the processing transformation and flow speed of production inputs. The application and development of mechanical automation technology is the main means of technological transformation and technological progress in machinery manufacturing industry and the main direction of technological development. The technical level of mechanical automation not only affects the development of the whole machinery manufacturing industry, but also has a great direct impact on the technological progress of various departments of the national economy

the emergence of mechanical automation

mechanical automation technology began to develop and apply in the cold processing mass production process of mechanical manufacturing in the 1920s. After the 1960s, in order to adapt to the needs and changes of the market and enhance the ability of the mechanical manufacturing industry to respond flexibly and quickly to the market, it began to establish a flexible automatic production system, that is, flexible automation around computer technology. Under the condition that the manufacturing system remains unchanged or changes little, the machine equipment or production management process automatically realizes the expected operation or a certain process through automatic detection, information processing, analysis and judgment, and can automatically convert from manufacturing one kind of parts to manufacturing another kind of different parts. Social practice has proved that manufacturing system automation under this definition is incompatible with the reality of most contemporary enterprises. At present, except for some production departments in a few industrialized countries, most of the mechanical automation standards in the world are still in the operation stage of automation. China is no exception. It needs to work step by step and make continuous efforts to create conditions to move forward to the advanced ideal stage of automation

current situation of mechanical automation

since the development and application of mechanical automation technology began in the 1920s, it has developed rapidly, especially in recent years, the highly integrated computer has begun to adopt computer integrated manufacturing system, which has greatly accelerated the development of mechanical automation, but China is still in the primary operation stage of automation. At present, except for some production departments in a few industrialized countries, most of the mechanical automation standards in the world are still in the operation stage of automation. China is no exception, and its industrial structure is low. At present, there are 114000 enterprises in China's machinery manufacturing industry, and their development is very uneven. There are a large number of industries that lag behind the modern level. Most enterprises are still relatively backward, and manual labor accounts for a considerable proportion. It can be said that there are no enterprises in China that can independently develop modern machinery automation technology; There are few automation equipment and low level in China's machinery manufacturing enterprises. There is not only a large gap with the world's advanced countries in quantity, but also a phased gap with the world's advanced standards in variety, quality and use. The realization of mechanical automation technology in China is a long-term process, which cannot be achieved overnight. It is necessary to make continuous efforts step by step to create conditions and move forward to the advanced ideal stage of automation. At present, China is still in the primary stage of socialism, and there is a big gap between China and the major countries in the world in terms of economy, financial resources, productivity level and national quality; China is rich in labor resources, with more than 20 million new urban employment every year. In the future, with the economic tension of the people, such as aerospace, national defense, kerosene chemical industry, transportation, and so on, the number of employment will increase. Mechanical automation maximizes labor productivity, and the surplus of labor and the transfer of division of labor is a practical problem

the development process of mechanical automation

mechanical automation technology began to be developed and applied in the cold processing mass production process of mechanical manufacturing in the 1920s. After the 1960s, in order to adapt to the needs and changes of the market and enhance the ability of the mechanical manufacturing industry to respond flexibly and quickly to the market, it began to establish a variable automatic production system, that is, flexible automation around computer technology. Under the condition that the manufacturing system remains unchanged or changes little, the machine equipment or production management process automatically realizes the expected operation or a certain process through automatic detection, information processing, analysis and judgment, and can automatically convert from manufacturing one kind of parts to manufacturing another kind of different parts

The realization of mechanical automation technology in China is a long-term process, which cannot be achieved overnight. At present, China's machinery manufacturing industry has 11 The development of 40000 enterprises is very uneven, with a large number of industries lagging behind the modern level. Most enterprises are still relatively backward, and manual labor accounts for a considerable proportion.

development trend of mechanical automation

Agricultural machinery automation

in recent years, foreign agricultural automation has developed rapidly, and agricultural machinery design is developing in the direction of high speed, wide width, high power and comfort. Automatic control technology has been widely used in agricultural machinery. Some famous manufacturers have applied modern cutting-edge technologies and equipment such as automatic control, information processing, global positioning system, laser and remote sensing to agricultural machinery. Due to historical, conceptual and technological reasons, there is a big gap between China's traditional agricultural machinery and developed countries, which is far from being able to adapt to the scientific and technological progress of agriculture. In recent years, the research of automation has been gradually recognized by people, and the application of automatic control in agriculture has been paid more and more attention

agricultural automation in China has been developed in greenhouse automation control, irrigation and drainage machinery automation, and some agricultural machinery automation in facility agriculture, especially the development of precision agriculture has been paid more and more attention. The rapid development of electronic technology and computer technology has promoted the development of agricultural machinery in the direction of automation. With the development of intelligent technology, artificial intelligence will be the focus of agricultural engineering development in the century. Various agricultural robots or intelligent systems will continue to emerge in agricultural automation control. To continue to promote and realize agricultural automation is a long-term topic and challenge faced by agricultural mechanization engineering technicians, and further promote the development of agricultural automation control technology to intelligent technology
