Automation and communication, electronic information these three majors to transfer to the computer major should be said to be the easiest. Basically, the most important core courses for computer majors are offered in automation majors, but they are simple versions. The main ones are: (Computer science courses on the left, Right for automation, electronics, communication courses) Data structure => Computer software technology basic database (difficult) => Database (simple) Computer network => Data communication and computer network/industrial control network (difficult) Composition principle => Microcomputer principle assembly => Microcomputer principle (difficult) Embedded system => Embedded system (quite difficult) Image processing => Image processing (quite difficult) Operating system (difficult) => Computer software technology basics (easy) Object-oriented programming (difficult) => Object-oriented programming (easy) Although a simple version is opened, but the reality is that if you want to learn things to learn through, You need to put in the same amount of effort as a computer major, but you also need to take electrical and electronic, control related courses, which are very, very time-consuming. In addition, the teaching level of teachers is not good enough, many computer professional courses because the automation/electronic and electrical school teachers are from this professional background, rather than computer professional background, they themselves are not good at mastering the above courses, and the quality is naturally poor. And because although it is a simplified version of the textbook, but many simplified version of the textbook can not tell things clearly, so in order to learn thoroughly, you must look at the computer professional textbooks. However, computer science courses are not easy, and even tiring (although computer and software majors in engineering are easy, I mean compared to electronics, electrical, communication, automation, aerospace, etc.). There is still a way out for computer majors to test civil servants, and automation is not available, and basically only unlimited professional tests can be conducted. Just to add. What you said is actually more in place, but the personal feeling is not very grounded. Let me make a point that I think is more grounded. First of all, to answer a question, what is the difference between automation and electrical, electronic and computer majors? At the same time, since there are highly relevant electrical, electronic and computer majors, why have automation majors? First of all, it is explained that in addition to learning electrical, electronic and computer professional courses, the automation major emphasizes the course “Principle of automatic control”. The essence of Automatic Control Principle is the mathematical modeling of control system. So the automation profession is essentially math. In addition, because it is now the information age, the brain of the automatic control system is a computer (generalized computer, including single-chip computers and various industrial control computers, PCS, PLCS, etc.), which is essentially computer control. So in addition to learning “Principles of Automatic control”, the rest of the course is mostly around the computer, and another part is around the motor, because the motor is a very common object to be controlled. That is to say, in addition to the automation major, other majors either do not learn the Principle of Automatic Control, or learn the simple principle of Automatic Control. At present, the main uses of computers are scientific computing, process control, information processing, aided design, intelligent simulation. Among them, process control is mainly done by automation majors, and computer majors mainly do information processing. In summary, automation is actually a good professional, the essence is to do computer control. Because the application of automation technology is particularly wide, from the reaction process control of chemical plants to the automatic production of the assembly line, from the automatic driving technology of automobiles to the control of missiles and aircraft, all aspects are involved in automation technology, which makes the learning has a huge sense of emptiness. When I studied software engineering, I knew from the first day of freshman year that I had to learn various software development technologies and make various desktop, web and mobile applications. Majoring in law, from the first day of freshman year, I knew that I should study civil law, criminal law, civil prosecution, criminal prosecution, and pass the judicial examination; Medical major, from the beginning of the freshman know to learn medicine and surgery, pathology, pharmacology and other courses, after graduation is to pass the medical practice exam, and then to enter the hospital to do internship doctor. For automation students, they do not know what the principle of automatic control is in their first year, and I believe that most people will regret it after seeing the principle of automatic control, why don’t I go on an electronic, electrical, computer major? This sense of emptiness is with automation students for a long time. All along, ABB has been adhering to the development strategy of “in China, for China and the world”. While helping customers to increase efficiency, save energy and reduce environmental impact with professional technology, ABB has actively implemented the relevant system standards of green manufacturing in its production and operation, made every effort to create green factories, establish green supply chains, and grow together with relevant parties to achieve sustainable development. Zhao Yongzhan, president of ABB Electric China, said that ABB is working with suppliers and partners to build a sustainable ecosystem through digital innovation and industry expertise, empowering the end-to-end low-carbon electrical industry chain and boosting the high-quality development of the local economy. At ABB, we take the concept of sustainability throughout, focusing on the main contents of green factories, green industrial parks, green supply chain and green product design, promote comprehensive energy conservation and emission reduction, and strive to fulfill the goal of achieving carbon neutrality in ABB’s own operations by 2030. Beijing ABB Switch Co., LTD., located in Beijing Economic and Technological Development Zone, is ABB’s largest secondary switchgear manufacturing center in China, mainly engaged in the design, manufacturing and service of 3.6kV-40.5kV medium voltage secondary switchgear and box-type substation. The company’s “Green Factory” project, launched in December 2020, has established an energy management system and obtained ISO50001 certification. At the same time, from the aspects of water saving, electricity saving, material saving, reducing emissions and other aspects of energy saving and low-carbon environmental protection improvement space and the implementation of the corresponding improvement projects, to achieve a comparable unit product comprehensive energy consumption decreased by 13% Speaking of unmanned scenes, the recent Beijing Winter Olympics must have left a deep impression on the athletes of all countries, when the athletes moved into the Winter Olympic Village, All kinds of AI and service robots are greatly shocked, there will be anti-epidemic robots when not wearing masks, food will “fall from the sky” when eating, stir-frying robots, distribution robots, tea and tea robots, etc., can be called the scene of science-fiction movies. Behind the emergence of these “black technologies”, it highlights the rapid development of “unmanned applications”.
