164 Chapter 164: Using a Scientific Method to Find BUG

After a lot of busy work, Xiao Wang, the technician who was cooperating with the experiment, gave the cut clothing model to Team Leader Li.

Team leader Li first compared the samples of the same model. The samples cut at any angle were very accurate, and almost no error could be seen through visual inspection.

If the cut out clothing model can reach this precision, it is already qualified!

However, when comparing a set of grading models of the sleeve model, Team Leader Li found a problem.In this large, medium and small sleeve model, the grading ratio of length and width is not equal, which does not meet the grading data of clothing.

"Mr. Xu, come and have a look! Is the software command incompatible in this situation? Or is the clothing computer model cutting machine malfunctioning?" Seeing this situation, Team Leader Li frowned and asked Xu Zhenming.

Upon hearing this, Xu Zhenming stepped forward and carefully compared the cut sleeve samples.He didn't understand the knowledge of clothing grading, so he consulted the leader Li, and found that there was a problem with the clothing model after grading.

However, he has confidence in the clothing computer model cutting machine produced by Yiming, and believes that it cannot be a hardware problem.

At this time, he, like Team Leader Li, had 100% confidence in his products, but suspected that there was a bug in the CAD software of Beauty Clothing!

Thinking of this, he smiled and said to Liang Frame: "Mr. Liang! According to my estimation, it should be an algorithm error in your software during the grading process!"

"Impossible! This set of CAD software for beauty clothing developed by our company has undergone countless trials, and it has never happened before!"

Liang Jian did not agree with Xu Zhenming's opinion.

However, their beautiful clothing CAD software does not have the function of measuring model data, but a set of fool-like reading and automatic grading clothing CAD software system.

It is impossible to survey the actual data of the sleeve model in the beauty clothing CAD software, and no one can convince anyone!

This is not easy!

Seeing this situation, Xu Zhenming frowned and thought for a moment.

Suddenly, his eyes lit up and he smiled and shouted to Wu Yan: "Director Wu! You immediately go back to my office and take my laptop!"

He thought of a way: read out the layout of the garment pattern stored in the computer board of the garment computer pattern cutting machine, convert it into a vector file, and input it into the AutoCAD software to measure the data of the sleeve pattern.

AutoCAD is a general aided design software, the data beam frame of surveying and mapping will be recognized by everyone!

I heard that Xu Zhenming can turn instruction data into vector graphics files, and Liang Xian agrees with this good method."Mr. Xu! Unexpectedly you have this kind of technology, the level of software development is top-notch!" He smiled and exclaimed.

Liang Jian did not expect that Xu Zhenming was not only proficient in computer hardware technology, but also proficient in software programming.

He didn't know that the electromechanical engineers or automation control engineers of Xu Zhenming's generation were basically all-rounders. They had to write code at the lowest level of the hardware to develop a set of software.

Unlike later programmers, the task of exchanging data with hardware has been handed over to software development tools, and a function can complete the data access function.In fact, the writing of industrial code is far more difficult than the development of application software. In order to ensure the simplicity of software instructions, many codes must be written in assembly language!

Xu Zhenming didn't want to explain much to Liang Ji about this, and he might not understand it!

Thinking of this, he smiled humbly: "Haha... Mr. Liang passed the prize! Sometimes, those of us hardware technicians have to bite the bullet and write some application software code!"

While the two were talking, Wu Yan led Er Liu in.

Er Liu graciously smiled, and took Xu Zhenming's laptop.

Xu Zhenming asked Xiao Wang, the assisting technician, to connect the data cable to the electrical control box of the computer model cutting machine for clothing.

He turned on the laptop, called up the comprehensive simulator software he had written, switched on the clothing computer model cutting machine, and read the instruction file of the clothing layout map stored in the computer board.

Soon after, the data transmission between the laptop computer and the garment computer model cutting machine ended.Xu Zhenming pressed the data conversion menu button, and after the computer calculated for a while, a layout drawing of a clothing model was automatically generated.From the visual inspection of the graphics, the layout drawing of this clothing model is exactly the same as the layout drawing in the beauty clothing CAD software.

"The graphics are exactly the same, but I don't know if the data is the same as the original one?" Seeing this, Group Leader Li whispered.

She made a very reasonable point, and this situation still cannot be counted.The graph depends on the data to speak, you cannot explain the problem by observing the shape of the graph outline!

After looking at Team Leader Li, Liang Jian and others, Xu Zhenming smiled and asked Liang Jian: "President Liang! Can your company's beauty clothing CAD software read vector files?"

Liang Box nodded and asked Team Leader Li to click on the drop-down menu of the Liren clothing CAD software, and found a vector file import button among the file input buttons.

Now that there is this vector file import function, it is easy to handle!

Xu Zhenming took out a 1.44-inch floppy disk from the computer bag, copied the clothing layout map he transformed into, and imported the 1.44-inch floppy disk into the notebook computer in the beam frame.

Group leader Li clicked the mouse to import the vector file of the clothing layout plan copied by Xu Zhenming into the beauty clothing CAD software.Then, she started to compare the two markers.No matter how the comparison is made, the two layout drawings are exactly the same, and the outlines are exactly the same.

"Mr. Xu! The layout of the garment you converted is very accurate, and the size of the layout generated by our beauty clothing CAD software!"

Seeing this scene, Team Leader Li blushed and smiled.

She was a little embarrassed, and felt that she had spoken a little too much just now and did not take care of Xu Zhenming's face.

In fact, those who engage in technology should be like this. Everything must be spoken with actual data, and words like "maybe and possible" are eliminated!

Seeing this, everyone else smiled kindly at her, comforting her with smiles.

Xu Zhenming doesn't matter. The step just now to compare the two markers is a step that must be taken in the entire test link.Even if Team Leader Li did not propose to compare the two clothing template layout plans, he himself would ask for a comparison to test whether the data is scientific!

"Haha... Leader Li, this is the first step!"

Thinking of this, he smiled and said, comforting Team Leader Li.Immediately, he opened the AutoCAD software in his computer and imported the layout drawing of the clothing model just generated.

Soon after, on the black computer screen, Xu Zhenming marked out the data size of the whole set of sleeve and garment samples. These data are automatically generated by AutoCAD software, and the accuracy exceeds a dozen decimal places. The accuracy is beyond doubt.

The technician Xiao Li brought a large vernier caliper with a range of 1.5 meters, and began to measure the data size of the entire sleeve sample in front of everyone.These size data is not much different from the standard data in the computer, and the error range is the largest, and it does not exceed 0.2 mm.

Except for some errors in the radian data, the data of length and width dimensions are very accurate, and can be consistent with the data surveyed in the computer!

Things are very clear at this point: the 2200*1800 clothing computer model cutting machine of Yiming Company is very accurate, and the accuracy error of cutting model will not exceed 0.2 mm.Among them, it also includes the error of detecting human reading!

Since Yiming's clothing computer model cutting machine is no problem.

So, it is obvious that there must be a BUG in the beauty clothing CAD software.

"How could this be?"

Seeing this scene, Liang Jian exclaimed in surprise.

His face was reddened, and his brow was slightly furrowed, thinking about the software algorithm.In any case, it should be a good thing that Xu Zhenming helped Liren Group find the software bug.Thinking of this, he came to Xu Zhenming's side with an apologetic smile, stretched out his hand and shook hands with Xu Zhen:

"Mr. Xu, thank you very much for helping us find out the software bug! We have no doubt about the accuracy of the Yiming clothing computer model cutting machine! Regarding the compatibility and matching test between the beauty clothing CAD software and the computer model cutting machine, it may It will be determined through a period of experimentation!"

He told Xu Zhenming that he was ready to immediately order a 2200*1800 clothing computer model to cut and send it to Xiangjiang, and hand it to the laboratory of the Liren clothing CAD software development team, and to find the software bug through experiments.

Regarding software bugs, Xu Zhenming shouldn’t see too much: For example, in some games, characters are stuck in the walls and cannot get out; in some games, the probability of equipment explosion in a certain place is particularly high... etc. .

These game softwares are not the same as professional clothing CAD software, even if there is a BUG, ​​the impact is not big.Once there is a bug in the CAD software of Liren clothing, which causes a product quality accident, Liren Group will compensate customers for economic losses.

This aspect is very important, so the beam frame is very important.

He decided to immediately end his visit to the production base and prepare for business negotiations with Xu Zhenming.Then, they will fly back to Xiangjiang immediately and organize manpower and material resources to find the bugs in the CAD software of Beauty Fashion!

Not long after, Xu Zhenming and others moved to the large conference room on the first floor of the company to discuss the order for four 128-head computerized embroidery machines and a 2200*1800 computerized clothing model cutting machine.

This order is worth more than 20 million yuan, excluding the preferential part to the agent, it will also be over 16 million yuan.Xu Zhenming asked Xiangjiang Liren Group to pay in U.S. dollars, and the price could be discounted by 1-2%.

For Xiangjiang Liren Group, payment in US dollars is the same as payment in Hong Kong dollars.Therefore, Liang Jian and others were very happy to sign the purchase and sales contract and chose to pay the purchase price in US dollars.

"Mr. Xu, happy cooperation!" After signing the equipment purchase contract, Liang Jian smiled and shook hands with Xu Zhenming.Then, he smiled and asked Xu Zhenming: "Why must your company choose to pay for the goods in US dollars?"

In his opinion, it is irrational for Yiming to lower its selling price by 2% and choose to pay for the goods in US dollars.

Looking at the expressions of Liang Jian and others, Xu Zhenming smiled slightly and said: "This is for the country to generate income in US dollars and foreign exchange, there is no way!"

This reason is so high that Liang Jian and others who heard this statement immediately awed in awe.
