Xu Zhenming invited the guests to sit beside the small folding table. The two exchanged business cards and sat down to chat.
"Mr. Xu! I think you are very young, is it a college student who graduated from China Science and Technology Junior Class?"
The beauty editor of "Fashion Clothing" looked at Xu Zhenming's business card, then looked at Xu Zhenming carefully, and asked with a smile.
Her name is Fang Ying, she is a bit of Beijing film, speaks slowly, has a good affinity, and is a sales veteran.Sales masters generally like to play routines and talk to customers in circles.If you enter the subject without knowing it, you won’t feel disgusted.
However, her marketing strategy used in Xu Zhenming's body was somewhat wrong.
Xu Zhenming likes to negotiate straightforwardly, and has no time to circle with others.He looked at Fang Ying, the beautiful woman on the opposite side, smiled and shook his head: "I am not a college student, I have never attended a university. I am an industrial worker, and I work as a fitter in my work unit!"
"Oh? Mr. Xu is young and promising! Mr. Xu's company must have a good relationship with the clothing association. These tables and chairs should be specially presented by the exhibition organizer!"
After being choked by Xu Zhenming, the intellectual beauty Fang Ying smiled awkwardly and changed the topic again.
She guessed wrong again. These folding tables and chairs were specially prepared by Yiming for the exhibition.
Xu Zhenming has run professional exhibitions for many years in his previous life and is very experienced.He knew that the exhibition organizer provided relatively few tables and chairs, so he deliberately prepared some portable folding tables and chairs, packed in the wooden box of the equipment, and shipped to the venue together with the equipment.Such detailed issues can only be considered by old exhibition people like him.
Regarding this question, Xu Zhenming really does not want to answer.So he asked straightforwardly: "Editor Fang, may I ask if you come to our company's booth? Just tell me if you have something to do. I have to receive Professor Lin!"
As he spoke, he smiled and pointed to the teachers at the Beijing Fashion Institute sitting aside.
"Don't worry! You talk first, we can wait!"
Teacher Lin, a female professor of more than fifty years, helped her black glasses frame and drank tea with a smile.
After being choked by Xu Zhenming again, Fang Ying couldn't help blushing.She looked at Xu Zhenming's face, smiled and ridiculed herself: "Hehe... I'm sorry! I didn't expect Mr. Xu to be a straight-headed man! That's the way, our "Fashion" magazine can provide your company with the opportunity to display products. Ours Millions of readers..."
Fang Ya talked endlessly, praising her magazine to the sky.
"Our products are used in clothing companies, not household daily necessities. Is it useful to advertise in your magazine?"
"It's definitely useful! Clothing companies will subscribe to our magazines to find inspiration for new styles of clothing!" Seeing Xu Zhenming doubting the audience of his magazine, Fang Ying finally came to the point.
She was very depressed: Why didn't her invincible and invincible routine in front of Xu Zhenming not work in front of Xu Zhenming?
"This little Mr. Xu is too young, the edges and corners have not been smoothed! I hope this order can be won!"
Fang Ying was a little worried and prayed secretly.
"Okay, I know the status of your magazine! Editor Fang, I will transfer your business card to the sales department of our company. They will send someone to contact you about advertising!"
After Xu Zhenming figured out the situation in "Fashion Clothes", he smiled and stood up to shake hands with Fang Ying.
Under normal circumstances, his actions are meant to see off customers in the mall.Now it’s not the old society. Use the etiquette of serving tea to tell guests that you should leave.
"Mr. Xu! Do you agree or disagree with advertising in our magazine? Can you give me a letter?"
Fang Ying was a little anxious, her cheeks blushed and asked.
She held Xu Zhenming's hand and held it, and she must get the letter before leaving.
Xu Zhenming couldn't help it when encountering such a person.According to his judgment: Yiming's advertisement for computer embroidery machines in Fashion is not obvious.With the remarks just now, he politely refused the intellectual beauty Fang Ying in front of him.
Right now, the big beauty Fang Ying forced Xu Zhenming to open her hole card, which made Xu Zhenming feel a little helpless.He shook his hand and said: "Editor Fang! After you go back, prepare carefully and come up with specific promotional plans that can impress our company! We will cooperate with your magazine!"
"Okay Mr. Xu! Thank you for giving me a chance to work hard!"
Fang Ying saw that Xu Zhenming hadn't completely blocked the door, although she was a little regretful, she left with a glimmer of hope.
After Fang Ying was sent away, Xu Zhenming sat down to formally receive Professor Lin and others.There were two teachers who accompanied Professor Lin.A female teacher is in charge of sales; another male teacher surnamed Yuan, wearing a pair of highly myopic glasses, is a software engineer.
The three of them came to Yiming's booth to test whether the clothing CAD software developed by their college is compatible with Yiming's computer embroidery machine.
After listening to their explanation, Xu Zhenming smiled and shook his head: "Professor Lin! Our computerized embroidery machine does not accept instructions in other formats. Unless you want to convert the file into a vector file format, open it with our dedicated CAM software for editing, and then Before it can be sent to the computer board of the computerized embroidery machine."
This method is cumbersome and basically eliminates data exchange with other software.Xu Zhenming actually took this into consideration when designing the software.He doesn't want to be compatible with other software systems at all!
"Professor Lin, it seems a bit difficult! Our clothing CAD software has to exchange data with their equipment, and we must rewrite the code. This workload is relatively large!"
After hearing Xu Zhenming's introduction, Teacher Yuan shook his head helplessly.He is engaged in software design and knows the difficulty of exchanging data between two kinds of software.Besides, he is not willing to rewrite the code for the CAM software compatible with Yiming Company.
Professor Lin is not tall, short and chubby, and speaks Peking dialect very well.She still did not give up and smiled and said, "Mr. Xu! Our Fashion Institute is preparing to develop a large-scale silk embroidery CAD software, and we want to buy a computerized embroidery machine from your company as a testing machine. Once this project is successful, the market potential is very low. small!"
Xu Zhenming loves to hear this sentence!
As long as there are business opportunities, he is still willing to expand the application industry scope of computerized embroidery machines.Thinking of this, he asked curiously: "Professor Lin, the work surface of our equipment is relatively small, I am afraid it is not suitable for the application of the silk textile industry. How big is the work surface of the computer embroidery machine you need?"
"With a width of two meters, continuous embroidery is possible!" Professor Lin said of his technical requirements.
As a result, the movement structure of the computerized embroidery machine needs to be changed.The machine head must be changed to move freely in the Y-axis direction, and the X-axis direction must drive the silk to move continuously.After this method is changed, there is no difference between the motion structure of the computerized embroidery machine and the plotter.
Considering this, Xu Zhenming smiled bitterly and said: "Professor Lin! According to your technical requirements, our company's computerized embroidery machine has to change a lot, and it works the same way as a plotter!"
"Yes, yes! Just like a plotter!" At this time, Teacher Yuan excitedly helped Xu Zhenming with his glasses frame and smiled.
Although this is an order, Xu Zhenming really doesn't want to do it.There is no technical difficulty, and the economic benefits are meaningless.The input-output ratio is not cost-effective, and he will not easily develop new equipment.
Thinking of this, he smiled bitterly and said: "Professor Lin, Teacher Yuan! It is not difficult for our company to develop the equipment you mentioned. However, without a certain demand, the core management of our company will not be willing to invest in manpower and Material resources!"
Not far away, the fat man Zhang Gui heard Xu Zhenming's reluctance, and couldn't help but curl his lips, and smiled in his heart: "The little brother will come here when he talks nonsense! When will the core management of our Yiming company stop your decision? ?"
Although he thought so, he dared not make a sound for fear that it would affect Xu Zhenming's business negotiations.This guy held back his smile, pricked his ears to listen to Xu Zhenming's conversation.
Seeing the appearance of the fat man shaking his shoulders, Xu Zhenming knew he was eavesdropping on the conversation here.As a result, Xu Zhenming deliberately turned his face, not seeing the fat man astonished as if he had never seen the world.
Professor Lin was disappointed after hearing Xu Zhenming's explanation.She is not far from retiring, and it took several years to develop her own clothing CAD software for overseas Chinese.Because of the success of this project, she was promoted to the deputy dean of the Beijing School of Fashion by the relevant leaders.
Before retiring, Professor Lin still has two wishes to fulfill.One wish is to promote domestic apparel CAD software and break the monopoly of foreign brand CAD software on domestic apparel companies; another wish is to develop a computerized embroidery CADCAM system for the silk textile industry.
Nowadays, computerized embroidery machines already exist. As long as they are improved and matched with the CAD software developed by themselves, the CADCAM system of the domestic silk textile industry has been successful.
Thinking of this, Professor Lin told Xu Zhenming the history and hardships of the development of domestic apparel CAD software.Especially when talking about the arrogance of foreign famous brand clothing CAM system suppliers, she couldn't help sighing.
Foreign well-known apparel CADCAM system suppliers include French cryptogram, Japanese Roland, two Italian companies and so on.These companies have their own CAD software and are unwilling to be compatible with domestic CAD software.This makes the domestic CAD software led by Professor Lin useless.
After hearing this introduction, Xu Zhenming was moved by Professor Lin, who was in his 50s.People in all walks of life need this pioneering spirit to progress.Otherwise, the Chinese people will make money for foreign businessmen, and they have to endure the arrogance of foreign businessmen!
Thinking of this, Xu Zhenming smiled and comforted Professor Lin: "Old Lin! I have benefited a lot from hearing your words. Let’s do this, we are responsible for the development of computer model cutting machines, drum-type computer embroidery machines and computer cutting machines in the textile CAD system. Bed and other CAM system equipment! All the above equipments are open interfaces for your CAD software!"
"Oh, great!"
Hearing Xu Zhenming's words, Professor Lin was very excited.
She took off the black framed glasses and wiped the wet corners of her eyes.Today, I came to the Yiming company's booth. She was purely trying her luck.
Hearing that Chinese people have developed a 15-needle computerized embroidery machine, Professor Lin is very excited and must take a look.As a professional in the industry, she knows the difficulty of developing a 15-needle computerized embroidery machine. Without considerable technical reserves, she can't produce this kind of professional equipment!
Since Xu Zhenming dared to pat his chest and said that he would develop computer model cutting machines, drum-type computer embroidery machines and computer cutting machines in the apparel industry, Professor Lin still believed that Yiming had such strength.
Professor Lin didn't know that even after more than two decades, the computer-cutting machines made by Chinese people are still dominated by imports.This kind of professional production equipment was arranged by Xu Zhenming on the R&D agenda of Yiming Company because of her remarks.
"Ms. Yuan! What format does your CAD clothing software use to output data? Can we try it out now?"
At this time, Xu Zhenming, who was aroused by Teacher Lin's self-improvement, asked with a smile on his face.
While talking, he took out his laptop and a self-made integrated microcontroller emulator.
Teacher Yuan saw this scene, and replied somewhat surprised: "Our clothing CAD software outputs HPGL format commands through the LPT port, and the COM port is also available!"
Immediately, he asked curiously: "Mr. Xu! You can do the experiment now, can you do it? This is a professional technique that requires an electrical engineer who is engaged in hardware to complete it!"
"We, Mr. Xu, are our company's electrical engineers!" At this moment, the fat man finally couldn't help it, and said with a big smile.
"Huh? Are you an electrical engineer?"
After hearing this news, Professor Lin, Teacher Yuan and the other female teacher were very surprised.
None of them thought that Xu Zhenming, who was only 18 or 19 years old, was actually an electrical engineer at Yiming Company.Eighteen or nineteen-year-old general managers are no longer seen, and there is probably only Xu Zhenming in the country who is an eighteen-year-old general manager and electrical engineer.
"Manager Zhang, if you don't speak, others won't treat you as dumb. Insert this data cable into the computer board of the single-head computerized embroidery machine!"
Xu Zhenming frowned and ordered the fat man too much.
He has always been a low-key person and doesn't like to pretend to be cows in front of others.
The fat man smiled carelessly, and plugged the extended data cable into the electric control cabinet of the single-head computerized embroidery machine.
Xu Zhenming opened his own special MCU simulation software and called out a library function and code file that had been written long ago from the computer file.
This program is mainly written to support HPGL instructions. As long as it is added to the chip of the computer embroidery machine, the computer embroidery machine can support Professor Lin's clothing CAD software.
Teacher Yuan is an insider. He was surprised to see Xu Zhenming calling out the code, recompiling the program, burning the chip... etc.!
He could understand part of the circuit design, but he couldn't figure out why Xu Zhenming used multiple single-chip microcomputer chips to control the computer embroidery machine.At the end, he couldn't help it, and asked curiously: "Mr. Xu! Why is the computer board of your single-chip computer different from others?"
The single-chip integrated simulator, single-chip computer board and single-chip simulation software designed by Xu Zhenming are different from everyone's. There is only one in the world.He did this just to prevent one thing.
Seeing that Teacher Yuan was very curious, he smiled and said, "I did this to put out the fire!"
"Fire?"
Everyone looked at Xu Zhenming curiously.
"Chip manufacturers leave backdoors in the machine language code! As long as we use their chips, some people can invade our smart equipment through special means in the future, thus harming our country's interests."
Xu Zhenming told everyone with a smile.
"how is this possible?"
Everyone was surprised, as if they heard a fairy tale.They all stared at Xu Zhenming with wide-eyed eyes, feeling that this kind of judgment was incredible.
However, this is the fact.
Xu Zhenming didn't talk nonsense, but took out a brand-new chip from the small box with the integrated emulator.Then, he inserted the chip into the socket of the emulator, turned on the power, and called up the machine language instruction set of the chip from the software he wrote.After a while, a special command was locked on the screen.
"Ms. Yuan! What use do you think these three instructions are for?"
Xu Zhenming pointed to the locked three instructions and asked Teacher Yuan.
Teacher Yuan is a software engineer, a university teacher, and a professional. Of course, he can understand the three instructions translated after being locked.He pondered for a moment, and frowned slightly and said: "These three instructions have no meaning. Even if they are not used, they will not affect the performance of the chip!"
"Yeah! Since it is a redundant instruction, I will destroy it! This is called fire fighting! Haha..."
Xu Zhenming smiled and pressed the Enter key to delete these three redundant instructions.
Xu Zhenming invited the guests to sit beside the small folding table. The two exchanged business cards and sat down to chat.
"Mr. Xu! I think you are very young, is it a college student who graduated from China Science and Technology Junior Class?"
The beauty editor of "Fashion Clothing" looked at Xu Zhenming's business card, then looked at Xu Zhenming carefully, and asked with a smile.
