Technology and life: starting with solar cars

Chapter 4 Solar Car Completion

The mechanical part that controls the lifting of the convex lens is done, and the next is the sensing part.The function of the sensing part is to sense whether the convex lens has formed a focus, and once the focus is formed, a signal to stop lifting is sent.

Before Liu Yunlai thought about whether to use a temperature sensor or a photosensitive sensor, he made a comprehensive decision and decided to use a photosensitive sensor.

In fact, it feels like both are possible.When the temperature sensor is set to detect that the solar panel reaches 600 degrees, it is considered that the focal length has been reached, and the lifting of the convex lens is stopped.When the photosensitive sensor detects the brightness of a 200w light bulb, stop the convex lens from moving up and down.

Both of them can detect whether the focus is formed more accurately, and the difference is relatively slight.

With all the required hardware in place, only the software remains.Once the software part is done, the rest of the assembly is much simpler.

Liu Yun told Deng Yunqi: "You can make a template and try it out."

Deng Yunqi left in a hurry, and there was an old man and a young man left in the room.

In order to avoid embarrassment in the cold, Wang Linqing said: "Let's take advantage of this time to fix the computer panel for you."

Then the software engineer Liu Jinwei was called.

It took a while for the software engineer to come over.

Liu Jinwei, a software engineer, stepped on sandals and walked unhurriedly, wearing a vest and holding a tablet computer in his hand.This casual outfit, coupled with his head without a single hair, gives people a very technical feeling.

As we all know, a strong programmer is not necessarily bald, but a bald one must be strong.

Liu Yun still has a little understanding of the programmer business, and many skilled programmers are very arrogant.

This kind of mentality is understandable. It is the nature of a person to be proud of his talents, coupled with the fact that programmers code all day long, and they are half an otaku with a slightly simpler mind, and it is easy to write arrogance on their faces.This makes many programmers look cold, but they are actually too nerdy.For other professions, this situation is less serious, especially for the top figures in sales, it is really warm and pleasant to speak.

Before Liu Jinwei could speak, Liu Yun said directly, "Hello, my name is Liu Yun. I came to you through Boss Wang to change the program of the car."

Liu Jinwei nodded, got into the car without saying a word, and plugged the docking port of the car into the port of the tablet.

Data from a bunch of cars is then displayed on the tablet.

He cherished words like gold and asked, "What do you need?"

"The first point: I want you to add an output line to the car battery. This line requires 12v output. When the photosensitive sensor of the solar panel sends a signal, the output of this line will be stopped immediately. Finally, add a line to the fuse box. Fuse, in case the circuit current is too large to burn out the motor that controls the convex lens."

Liu Jinwei nodded, took out a piece of A4 paper from the back of the tablet, and wrote the code on the paper with a ballpoint pen.

The code is written a bit like cursive, almost full of professional style like a doctor's font.

#NewClass{}//**C# language, create a new class to call other interfaces.

The C# language code is full of paper.

Then he nodded again, feeling that he should complete the new function, and wrote the code on the tablet in a smooth manner.

There are more and more codes, which are obviously several times more than on paper.

Liu Yun was extremely shocked.This Liu Jinwei is really a great god. He has thinning hair and writes codes on paper. He has reached the realm of human-code integration.

This made Liu Yun love talent, cast a glance at Wang Linqing, and asked software engineer Liu Jinwei cautiously: "I wonder if this master is interested in coming to our company for a job?"

There is no way, he is the only one in the company now, what if he doesn't poach people, should he do everything by himself.

Wang Linqing was stunned, and then smiled at Liu Yun, "Don't be embarrassed, who doesn't like talents. If you need a software engineer from our company, I can lend you a period of time. Of course, if this engineer Liu Jinwei If you are willing to follow you, I will not stop you, I still have a bit of guts."

Hearing this, Liu Yun didn't care about saving face anymore.Looking eagerly at the unshaven Liu Jinwei.This kind of talent must be available in the company. In the future, not only cars will need to be coded, but other products may also be used for coding. Hiring a long-term worker who writes codes will save you from asking for help.

He suppressed the longing in his heart, and said to Liu Jinwei: "Come and do it with me, I can give you an annual salary of 100 million, okay?" Liu Jinwei didn't respond.

"Give you an annual salary of 100 million including room and board?" Liu Jinwei still didn't respond.

Rub, really don't bend down for money.Liu Yun started to get ruthless, and he used a big move, "I'll assign my wife, okay?"

Liu Jinwei did not speak, but nodded calmly.It's just that the pupils of his eyes keep shrinking, which shows that his heart is not calm and his excitement is broken.

He has worked in this company for so many years, and the boss didn't say to assign him a daughter-in-law, he just knew to give him salary increases, benefits and these useless things.Still, this new boss understands him and knows that what he needs is not money but an object, Liu Jinwei is very happy.

At this time, he seemed to have been beaten with chicken blood, full of energy and full of drive.

He asked Liu Yun loudly and excitedly: "Boss, do you have any codes to write? Tell me quickly. I like writing codes the most. Writing codes makes me happy."

When people are happy, they can even talk more.

After Liu Jinwei's reminder, Liu Yun realized that the conversation was a bit off topic.

刘云满意的看着自己的员工刘金伟，“我还有一个需求。你也知道咱公司要制作太阳能汽车，所以我希望汽车在行驶的时候1/4的电池充电3/4的电池用来供给汽车。等1/4的电池充满后，再换1/4电池继续充电。”

Charging the battery while putting it away has a little impact on the life of the battery, so he plans to logically divide the battery into two groups.One set of batteries is used for charging, and the other set of batteries is used to power the car.

Continuously logically divide the battery into two groups to realize the separation of charging and discharging functions.

Liu Jinwei nodded, this time he didn't write the code on paper because he was too excited.

Open the tablet directly to dry.

The code is line by line, at the speed of 1 letters in 20 second.

It has truly reached the point where there is no code in the heart to shoot the natural god.

After 20 seconds, he let out a long breath and said, "so easy. In addition, I have written your two requirements into the system process, and these two functions will start to work after the car is turned on."

Now everything that needs to be prepared is done, only the assembly is left.The assembly is simple, nothing more than connecting the already made things together, without any technical content.

Everything is ready, waiting for the day of the exhibition to see if it attracts customers to buy.
