Chapter 238: Expanding new ideas

"What is a microcontroller?" Shui Rou asked a question.

Although she introduced Shao Min to Chen Mingluo and used computers at home, she really had no idea about this microcontroller. After all, the major she studied at the beginning had nothing to do with this.

"Single-chip microcomputer is actually considered a computer without an input and output system." He Tong signed this business and was in a good mood. He explained to her as soon as he heard this.

Single-chip microcontrollers are typical embedded microcontrollers. They were first used in the field of industrial control and developed from dedicated processors with only CPUs in the chip. The earliest design concept was to integrate a large number of peripheral devices and CPUs into one chip to make the computer system smaller and easier to integrate into complex control devices with strict volume requirements.

After the 1990s, with the great development of consumer electronic products, microcontroller technology has been greatly improved.

"Because microcontrollers are more suitable for embedded systems than dedicated processors, they have obtained the most applications. In fact, microcontrollers are also the largest number of computers in the world. Almost every electronic and mechanical product used in modern human life will be integrated with microcontrollers." He Tongxiang Shuirou introduced, "Mobile phones, calculators, household appliances, electronic toys, handheld computers and mouse are equipped with one or two microcontrollers, and there are also a large number of microcontrollers working in personal computers. For example, in cars, they are generally equipped with dozens of microcontrollers, and hundreds of microcontrollers may even work in complex industrial control systems. Therefore, the number of microcontrollers far exceeds the number of other computers."

As He Tong said that, he flipped out a single-chip chip from the drawer and handed it to Shui Rou, asking her to see the true face of this thing.

After hearing this, Shui Rou felt a little confused. She looked at the microcontroller chip again and felt that it was really different from the computer she had in her impression. "In my impression, it seems that only those with monitors, keyboards and mouses can be called computers. I really can't accept this kind of thing."

Chen Mingluo laughed when he heard this, "The microcontroller integrates a computer system into a chip, which is equivalent to a microcomputer. Simply put, a chip becomes a computer. However, it is small in size, light in weight, and cheap in price. Learning to use a microcontroller is the best choice for understanding the principles and structure of the computer. The difference is that the performance of these components is much weaker than that of our home computers. Of course, using it to do some not-so-complex tasks such as controlling electrical appliances is enough."

"You seem to know more about this?" Although Shao Min is not a microcontroller, she usually deals with this. After hearing Chen Mingluo's words, she asked, "When I talk about this to the students, they don't think it's easy to accept."

"I usually like to read some idle books, and computers are no exception." Chen Mingluo replied.

He Tong nodded and said, "It is beneficial to open the book. In fact, once various products are used as microcontrollers, they can upgrade the product. Usually, you can add an adjective before the product name, intelligent. Nowadays, the products produced by technicians or other amateur electronic developers are either too complex in the circuit or too simple in the function, and are easily copied by others. The reason may be that the microcontroller or other programmable logic devices are not used in the product."

"Smart home appliances are a development trend-" Shao Min agreed.

After hearing this, Chen Mingluo suddenly had some thoughts. He patted his head and said, "You can think carefully about smart home appliances."

In Chen Mingluo's impression, smart home appliances are nothing more than two types: one is to use advanced technologies and equipment in electronics, machinery, etc., and the other is to simulate the experience of skilled operators in the family for fuzzy reasoning and fuzzy control.

For example, by combining computers and CNC technology, CNC refrigerators, rice cookers with fuzzy logic thinking functions, variable frequency air conditioners, fully automatic washing machines, etc.

The intelligence level of smart home appliances is different, and the intelligence level of the same type of products is also very different. For example, in a fuzzy rice cooker, detecting the rice volume and performing corresponding control is a process that simulates human intelligence.

The intelligent control technology used in smart home appliances is mainly fuzzy control. Fuzzy control technology is consistent with human thinking, which is more convenient to understand and does not require advanced mathematical knowledge expression. It can be constructed using a microcontroller.

However, there is also one disadvantage in fuzzy logic and control technology, which is that it does not have the ability to learn, so fuzzy control home appliances cannot accumulate experience. The acquisition of knowledge and accumulation of experience and the emergence of new thinking are the most obvious manifestation of human intelligence.

During the operation of household appliances, there are problems with external environment differences, internal parts loss and user usage habits, which requires household appliances to learn these states.

For example, a washing machine has different external environments in the four seasons of spring, summer, autumn and winter. Due to the different water temperatures and ambient temperatures, the washing machine should be able to automatically learn the washing procedures in different environments.

In addition, in many times of washing, the washing machine should also automatically learn the optimal washing program under the condition of specific clothes and clothing. When the user puts different amounts of clothes and different quality of clothes, the washing machine should automatically enter the optimal washing program after learning, which requires a brand new intelligent technology to achieve.

In China, the application of smart home appliances is still a relatively vague topic.

After all, the reform of state-owned enterprises is still in an extremely difficult period, and whether it can successfully transform smoothly is still between the two. As for the transformation from ordinary home appliances to smart home appliances, not many people can see this hope.

Chen Mingluo recalled that he felt that the proposal of smart home appliances in China was not popular until two thousand years later, but at that time, it was still rare. Later, it took a few years to truly realize the promotion of smart home appliances.

The reason is that manufacturers are somewhat unable to let go of their applications in this area, merchants have too high profit expectations for this type of product, and the other is the cost of microcontroller chips. After all, this thing basically depends on imports, and the price factor is an important factor that cannot be popularized smoothly.

It can be said that without the domestic chip industry, it will be difficult to truly realize the intelligence of home appliances.

"The trend is going to be the trend--" Chen Mingluo couldn't help but sigh lightly when he thought of this.

"What?" The three of them asked in surprise without hearing Chen Mingluo's words clearly.

"Hmm--" Chen Mingluo touched his chin and asked a question, "From this year, there will be no allocation for freshmen recruited by colleges and universities?"

"Well, there is no allocation." Shao Min and He Tong both nodded and affirmed.

The so-called package allocation means that the state is responsible for the unified allocation of work for graduates of ordinary colleges and technical schools according to the plan. That is to say, as long as you get admitted to a college and technical school, you will become a member of the country and will become a state cadre after graduation.

The non-issuance means that the employment system of college freshmen who have been recruited this year has changed after four years of graduation. After the reform, the employment of graduates has changed from being passively assigned to actively choosing jobs. Under the guidance of national policies and policies, a system for graduates to choose occupations within a certain range and employers to recruit merits. For a few unemployed graduates, the state will no longer be responsible for arranging work.

Regarding this, the country is naturally getting rid of the burden, and it also explains a problem, that is, the social employment problem is indeed very problematic, and the government is no longer able to work hard on these things.

Several major policies introduced at the same time, such as the reform of the medical system, the reform of the housing system, and the overall increase in tuition fees in colleges and universities, are all passing the heavy burden on ordinary people.

It should be said that when houses are not allocated, medical care is no longer public, schools charge high fees, and work is no longer allocated, several major foundations for the founding of the country have collapsed. Now they are just reluctant to throw them away under a guise, and the nature of the entire society has begun to slowly turn.

When Chen Mingluo mentioned this issue, he naturally didn’t have any other ideas. He was just thinking that this was a great opportunity for private enterprises to enter a period of rapid development.

Chen Mingluo believes that the biggest difference between state-owned enterprises and private enterprises is not a policy inclination, nor a system inseparable, nor a fund in the gap. The only difference is the different sources of talents.

In the past, it was difficult for private enterprises to recruit more college graduates. Most people like to enter state-owned enterprises and become state cadres. In recent years, due to poor management of state-owned enterprises, many people have begun to consider whether to enter more dynamic private enterprises as a better choice.

Under such circumstances, the reform of the national employment system for college graduates has undoubtedly broken the balance and allowed more college graduates to see the benefits of entering private enterprises. Since state-owned enterprises cannot count on them, some private enterprises with good operational potential may not be everyone's new goal.

Of course, Chen Mingluo's thinking should be further improved. He has begun to consider whether he can focus on cultivating the talents he needs in colleges and universities from now on.

For example, in the research and development of smart home appliances, can we cultivate a group of microcontroller R&D talents that we will continue to work as the basis for our R&D team to enter this industry in the future?
