Chinese entertainment for engineering students

After thinking about it, Wang Xu felt that it was unnecessary. Various technologies for this project will be placed in the technology pool, and the Sumhe Research Institute will have limited authority.

I believe that their research institute has a plan, and no one can refuse this seemingly profitable deal.

However, he still released further research directions based on existing results, mainly focusing on the attempts of various materials for positive and negative electrodes, such as ternary lithium batteries.

At the same time, he also further announced the research and development plan for battery management programs, as well as research topics on battery packs and new battery packaging methods.

Of course, these contents are not without purpose. This thing is linked to his electric car plan. At this time, the Shuimu Automobile Department actually has a research plan for electric cars.

However, due to limitations in materials and technology, they are currently focused on short-distance, slow-speed vehicles such as golf carts, tour buses, and rescue vehicles used in stadiums.

What many people don’t know is that Shuimu has actually been in the field of autonomous driving very early. Many big names in the field of autonomous driving have emerged in later generations, such as Chen Yilun of Huawei’s autonomous driving. He has a bachelor’s degree in electronics and a master’s degree in the University of Michigan. PhD.

Recently, Wenjie and Avita, which have been particularly popular on a certain music channel, were created by this man and his team.

In fact, there are many more people, especially in the computer and automotive departments, who have produced many leaders in this track.

In this life, there will probably be more. Who made Wang Xu light up almost all the basic technologies required for electric vehicles and autonomous driving in advance?

This is actually an unintentional move. Wang Xu started his career in artificial intelligence. Well, let me remind you, he is not engaged in materials, that is just for fun. His major is artificial intelligence.

Neural networks are a universal basket. The gradual expansion of deep learning and breadth learning, coupled with the improvement of various computing power and the various large models formed by learning methods of massive parameters, have slowly expanded into Various artificial intelligences that are well known in later generations.

But the foundation has already been laid in the papers published one after another by Wang Xu and his artificial intelligence laboratory.

In the past year or so, since the blue light LED, Wang Xu has basically stopped signing his name on various inter-professional papers. He has almost faded out of all academic activities except condensed matter physics and artificial intelligence.

The speed of publishing papers is no longer so exaggerated. Several high-quality SCI papers are published every year, all focusing on the graphene fields of artificial intelligence and condensed matter physics.

At this level, he can be considered a monster at best, and he can no longer be called a god.

On the one hand, the reason is that even though it was only a little over a year, Mizuki's professors have grown so fast that it is jaw-dropping. It is enough for Wang Xu to be more of a guide.

On the other hand, it is also the strategy of hiding one's strength and biding one's time as given above. Speaking of how to hide a shining star, of course, let him be among the stars. This is what Wang Xu did, to make himself less dazzling and gradually hide himself among the stars.

With the basic algorithm of artificial intelligence, autonomous driving is just a matter of course. After all, future autonomous driving is basically based on various large models of artificial intelligence.

Another core of autonomous driving is the chip. Well, it’s a chip again, but this thing is actually the same technical line as the large-scale floating-point computing unit developed in Wang Xu’s second-generation supercomputing plan.

If we continue to work on it, at most we will add some special instructions in the direction of artificial intelligence, then we will have a professional artificial intelligence chip, and there will be almost no bottlenecks.

Not to mention the battery, motor, and electronic control parts of electric vehicles, Wang Xu has already developed the most difficult battery, and even the most complex battery management and battery pack technology has been established.

In the future, as long as money is invested in motors and electronic controls, it is almost impossible not to be able to produce them. Even if they cannot be produced, then there will still be Academician Ma in the future.

Well, okay, Wang Xu has shown off his cards. He won’t pretend anymore. What about electric cars and autonomous driving? Isn’t that the outpost of unmanned XXX?

Therefore, although Wang Xu has never even mentioned the name of electric vehicles, in fact, the technical reserves needed for this thing in the future have been completed unknowingly and quietly.

What is this called? Those who are good at fighting have no great achievements? Actually no, this is just an inevitability of natural science. Electric vehicles are just an engineering practice of natural science.

Once the foundation is laid, future supercomputers, artificial intelligence, electric vehicles, and even various big toys are just engineering practices one by one.

This is also the tone that Wang Xu has set for Shuimu. This is his base camp. It is enough to focus on basic research. After certain results are achieved, the students who study this will almost graduate.

Then there will be technology spillover, whether students start their own businesses or work in other universities or companies. Naturally, there will be colleges and universities that focus on engineering practice to take over, either in depth or integration. At that time, it was beyond what Wang Xu could have imagined.

Never underestimate the creativity of the Chinese people. They can make heartless cannons with gasoline cans.

Similarly, after these technologies enter the technology pool, commercial companies that are more focused on profit will naturally develop them commercially, form products, and earn profits. At the same time, they will also naturally give monetary returns to the technology pool, forming a A cycle of positive motivation.

In fact, Mizuki did the same thing in his previous life. A lot of basic research was done here. However, ordinary people don't understand basic research, and the marketing accounts talked nonsense, which made everyone on the Internet shout.

The Mizuki expert was doing what he was doing all day long, and the Mizuki professor was doing what he was doing. I dare say that 99% of netizens have never paid attention to even one Professor Mizuki. So who made these Professor Mizuki’s remarks spread so widely?

Some people are afraid that the world will not be in chaos, so they ask a question, if Emperor Shuimu is destroyed, who will benefit the most?

Seven sons of national defense? Don't be ridiculous, there will only be a new Emperor Mizuki among them, and he will become a new target.

I'm going too far, keep your eyes open, there are many things that you will know the answer to if you study them in depth, if you are interested, I will write a free chapter about them.

However, what Wang Xu is most happy about now is of course the solution to the battery system, which can put his drone technology on the agenda. His movies are indispensable for various panoramic tracking shots. In these days, aerial photography is not ordinary expensive.

Not only do you need a specialized helicopter, but you also need a professional photographer. In the era without gimbals, just carrying a camera on a helicopter without shaking was a skill that only a master craftsman could have.

Therefore, Wang Xu planned to take advantage of this movie to build this drone, then make a gimbal and mount a new camera in the sky.

Well, that's right, he finally bought the camera technology. After thinking about it for more than a year, Wang Xu finally bought it yesterday after saving enough points.

The technical sorting out will take quite some time, and it involves a lot of electronic chip technology.

Not only CMOS photography photosensitive chips, but also central processing units for high-speed image processing, high-performance storage hard drive chips, large internal memory chips, cache chips, control chips, artificial intelligence chips, and even IGBT chips.

Anyway, let's put it this way, most of the chip types that Wang Xu knew in his previous life are almost all involved here.

Wang Xu held back his excitement and did not delve into the production process of these chips carefully. The catalog of information alone was enough for Wang Xu to spend a month sorting it out. At present, he did not have that much time.

Of course, Wang Xu believes that it will be another big surprise, but the difficulty will definitely not be low.

Wang Xu has become more and more understanding of what the system provides. Generally speaking, technology should be slightly ahead of the state in the previous life. In the previous life, semiconductor processing had basically entered the physical bottleneck period.

The latest fruit phone with a bunch of pro plus max and other BUFFs, the performance of the A17 chip installed in it seems to be far from expected.

This is a clear proof that the blown 3nm is actually much better than the actual 7nm.

Going forward, perhaps the materials should be changed, such as carbon-based chips. This is what Wang Xu expects from the system. The previous growth method made it impossible for Wang Xu not to have such expectations.

The first task now is to build a new type of camera. Yes, there is not only one kind of digital camera, and there will not be only one kind in the future. What Wang Xu wants to build first is a film camera.

Various digitalization needs

It’s not like Wang Xu didn’t consider importing and buying a few, and then put them on a gimbal, but the current cameras are too heavy to hold them. A camera weighs twenty to thirty pounds, and some of them weigh forty or fifty pounds.

This weight is a bit troublesome. Although it is not impossible to solve it by expanding the drone platform, it is purely a method of adding water when there is too much noodles, and adding noodles when there is too much water. Wang Xu does not want to play with it.

Now that there is a new technology, and even all of your points are consumed for it, of course you still have to make it work as much as possible.

Among the series of cameras, Wang Xu first planned to realize a handheld 35mm camera, yes, a handheld one with its own gimbal.

The camera weighs just over four kilograms. With the film loaded and the gimbal, the total weight does not exceed eight kilograms. This is already the most ideal load that Wang Xu can achieve now.

But the problem is not big. High-power small DC motors are not difficult to find now, and imported ones are still available. Although they are a bit expensive, he announced the research project very early, and it is still in progress.

But the overall progress is still very good. This thing was undertaken by the Department of Electrical Engineering. A professor and two PhDs are working on it, and the funds are relatively sufficient. Now we have a laboratory prototype, and the basic performance has met the design requirements, but the stability is still lacking. Not enough, still improving.

Various adjustments and the production of engineering prototypes are still being carried out, and it is estimated that the output of industrial products will be available in up to half a year.

The design of this thing is not difficult. What is difficult is the processing accuracy and durability, as well as the control of its own weight. The motor is similar to an aero engine. When used on a quadcopter, the main focus is accuracy and lift-to-weight ratio.

The higher the accuracy, the less pressure on the control software, and the greater the lift-to-gravity ratio, which means the greater the load it can bear. Wang Xu has played with drones a lot in his previous life. Even if he is not a top expert in this field, the general content still does not faze him.

The handheld camera comes with a gimbal, and the gimbal contains a kind of motor that is not available in China now, a servo motor.

In fact, the camera also comes with a motor for rolling film. Based on the system's consistent performance, these two motors are probably not simple things. Wang Xu directly took out the drawings and processing technology and threw them to Brother Yuzhuo. The kind that can be made regardless of the cost.

Looking back, Wang Xu also plans to see if these two things can be used on drones. If they can, then the power problem will be no problem. Wang Xu feels that there should be no problem. Don't look at it, it's just a roll of film. The power requirements and accuracy requirements are both high.

Moreover, the basic principles of motors are not complicated. They are often achieved through some special patented designs to achieve effects such as energy saving and increased precision. Wang Xu can naturally separate these things and apply for patents himself.

As long as you have a patent, simply enlarge or reduce some of the original design based on the basic data of the sample, and then slightly optimize it, it will be a new product.

This is actually not inconsistent with the motor research and development tasks he released before. The things provided by the system are often too advanced, either absolutely high-end products that are extremely expensive, or they are simply impossible to sell.

If Brother Yuzhuo wants to make money, he must not just rely on selling high-end products, but must come up with some mid-to-low-end solutions. At this time, Shuimu's motor solution comes in handy.

The performance index requirements proposed by Wang Xu are not low. The direct reference is the motors used in later generations of DJI drones. Whether it is the personal toy-type Elf and Mavic series, or the engineering-type RTX series, Wang Xu has played with them all. As an engineering major Male, they have also roughly studied the parameter indicators.

This also forms the basis of Wang Xu’s indicator requirements for the study. After all, DJI has been tested by the real market. Well, even the battlefield has tested these gadgets.

No matter what Wang Xu does, there will be dedicated people watching now. Wang Xu wants to develop civilian drones. The flight control aspect is not something that Wang Xu, a layman, can handle, but it is not a big problem. Imperial Capital Aviation Academy He and Mizuki have become very close recently.

They have done quadcopters before, but it's just not cost-effective to make them the way they do. This kind of flying method that completely abandons the lift of the air is really not in the eyes of people who make aircraft.

That would cost a lot of energy. Whether it is burning oil or electricity, a four-rotor can fly up to half an hour at most, while the same energy can allow a fixed wing to fly for half a day, with a range of dozens of times longer without any pressure.

Even hovering is not as good as a traditional helicopter structure. After all, the more rotors there are, the more troublesome it is to control, and the higher the requirements for the control system. It is difficult to control multi-rotor equipment to achieve stable flight with the previous level of electronic control.

However, four-rotor, six-rotor, and eight-rotor are the most suitable unmanned aerial vehicles for civilian use. After all, due to the limitation of remote control distance, you cannot fly too far, and you will not be able to come back if you go too far.

Moreover, multi-rotor hovering is more stable, and the lift redundancy is relatively large. Even if one and a half of the rotors are broken, it can be stabilized through good flight control and fly back smoothly.

It is a pity that these are just Comrade Wang Xu's assumptions. They were good ideas, but reality slapped Wang Xu hard.

Wang Xu always felt that this thing should be quite simple. After all, in the Yiwu Commodity Market in later generations, you could buy a quadcopter for 50 yuan.

But Wang Xu still underestimated the difficulty of this idea in this era. Therefore, when Wang Xu announced this scientific research task in the mercenary world, no one responded at all.
