It turns out that the second workshop of Feiyu Technology is a nearly unmanned production workshop, which contains 12 large-scale high-end CNC machining centers, 28 medium-sized high-end CNC machining centers, and other supporting equipment.
This workshop is responsible for processing parts that require the highest precision among Feiyu Technology products.
But this morning, when a process was being carried out, the software of one of the large CNC machining centers encountered an abnormality, and a chain reaction occurred immediately. All 4o high-end CNC machining centers in the entire workshop were paralyzed.
Since this workshop is responsible for producing the parts needed for the Mars plan, the security personnel reported to the superiors, so Ning Shuangshuang came here.
Ning Yuze led the two of them to the second workshop. Outside the workshop, Du Qiu saw armed police soldiers standing guard, which showed that the place was heavily guarded.
Tang's Mars plan aims to complete the three major detection missions of orbiting, landing and patrolling in one launch.
No country has accomplished this. Like the United States, which is the most accomplished country in Mars exploration, these three major missions are all accomplished separately.
Therefore, for equipment used for Mars exploration, the precision requirements for components are extremely high.
At this time, a situation occurred in the second workshop responsible for parts processing. Ning Yuze was very anxious.
The three of them changed into dustproof clothing and entered the second workshop.
The CNC machining centers in the entire workshop are arranged neatly according to the parts production process. At this moment, in the middle of the workshop, about five or six people are discussing around a CNC machining center.
"Dr. Ye, do you think there is something wrong with the motor driver?"
"I can't make a conclusion yet. Judging from the current performance, it seems to be the case, but it's best to deal with the tool magazine shift fault first."
"Teacher, do the production line control procedures need to be checked?"
"No need to do that. The problem is mainly with this machine tool. Other machine tools will automatically stop because of problems with this machine tool and disordered processes."
…
One of these people saw Ning Yuze and the others and hurriedly came over to greet them.
"Chairman, are you here? I invited Dr. Ye Haibin from the Machine Tool Research Institute. He is an expert in the field of CNC software in China. He returned from studying in the United States and is familiar with Harth's equipment..."
"General Manager Tang, have you found the cause of the problem?" Ning Yuze asked.
Hearing the two people talking, several other people stopped.
One of the middle-aged men with a medium build came over and said: "Hello, Chairman Ning, I am Ye Haibin."
"Dr. Ye, thank you for your hard work. I wonder if the cause of the fault has been found?"
Ye Haibin frowned and said: "It has not been completely confirmed yet. We are investigating one by one. It is initially confirmed that there may be a problem with the motor driver. However, due to the shutdown in the middle, there is also a problem with the tool magazine shift, which needs to be eliminated first."
At this moment, another short middle-aged man came over and said with some doubts: "I don't think the conclusion should be drawn so quickly. At least the servo motor is in good condition now, and it doesn't look like there is a problem with the drive..."
"Vice President Zhao, we asked Dr. Ye to help diagnose the cause of the fault. It's best to give him a certain amount of trust. We can't just ignore it just because of disagreements."
Chief Engineer Tang interrupted Vice President Zhao with a look of displeasure on his face.
Looking at this scene, Du Qiu suddenly understood that the relationship between Vice President Zhao and Chief Engineer Tang was probably not very harmonious before, otherwise they would not be able to argue on such an occasion.
Ning Yuze said: "In this way, you can think about it carefully. Xiao Du, go up and take a look."
He waved at Du Qiu, surprising everyone else.
Who is this young man? The chairman actually asked him to go up and check the fault.
Ye Haibin's face looked a little unhappy. He looked at Chief Engineer Tang and saw that Chief Engineer Tang shook his head at him, so he said nothing.
Du Qiu didn't care about this. He walked to the CNC machining center in a few steps, walked around the equipment first, and then checked the fault code reported by the equipment on the console.
That long list of fault messages would make most people’s scalp numb.
But in Du Qiu's eyes, he seemed to see something inner.
About ten minutes later, Du Qiu left this equipment and went to other equipment.
The student assistant brought by Ye Haibin saw this and couldn't help but sneered, "This equipment is faulty, what is he going to do to check other equipment? Does this person understand it?"
"Xiao Wang, don't talk nonsense!" Ye Haibin pretended to scold.
Chief Engineer Tang approached Ning Yuze and asked: "Chairman, this is..."
"Oh, he was invited by me. He is a rising star in the field of CNC software."
Mr. Tang was stunned. Since when has there been any rising star in the field of CNC software?
Vice President Zhao followed over at this time, leaned next to Du Qiu and asked: "Have you checked other equipment, do you suspect there is a problem with the production line process control program?"
Du Qiu smiled and said, "I'm not sure yet. I won't know until I read them all."
Then the topic changed: "Oh, Vice President Zhao, these equipments of yours are all products of Harth Company. If something breaks down, why don't you ask someone from Harth Company to repair it? They have a branch in Magic City."
Vice President Zhao smiled bitterly and said: "The parts processed here are confidential tasks. If Americans are allowed to repair the equipment, wouldn't that be a leak?"
"In the past two years, some aviation and military enterprises have changed the software of Central Data. Why haven't you changed it?"
"Our accuracy requirements are very high. If we replace their software with it, there will be a lot of problems."
After Vice President Liu finished speaking, he took advantage of the situation and asked: "The chairman invites you to come, are you sure you can fix this fault of ours?"
Du Qiu was noncommittal and looked at all the machining centers in the workshop. Then he asked: "Was there anyone in the workshop before the failure?"
"Oh, this is an unmanned processing workshop, but there were two engineers on duty. They were not in the workshop at the time. When they saw the equipment alarm light came on, they stopped the entire production line in time."
"Then which company made the layout of this production line? And which company used the full-line automation control system?"
"We did the layout of the production line ourselves, and the full-line automation control system is from Huhai Precision Control."
"Huhai Precision Control? Is that the company that was acquired by an American company the year before last?"
Vice President Zhao looked sad and said: "Yes, in the past, there were three domestic automation software companies to choose from.
In the past two years, the founder and chairman of the company in Imperial City have left and the company has been acquired. This company in Magic City has not escaped being acquired by foreign capital. The founder of the company in Hangzhou has just been released from prison. Although it has products, we don’t dare to use them.
.”
After Du Qiu finished the inspection, he clapped his hands and said, "Are you afraid that the chairman will be arrested again, the company will collapse, and there will be no follow-up services?
However, if you use Huhai Precision Control’s software, you can’t ask someone to handle it if something goes wrong, so it’s still the same thing.”
Vice President Zhao's eyes lit up and asked: "Have you found out that the fault is a problem with the production line's automatic control system?"
"pretty close."
The two walked back to the faulty equipment, and Ning Yuze asked: "How was it? Have you found out the cause?"
"It should be a problem with the production line's automatic control system. This problem is not simple."
Dr. Ye Haibin showed disdain on his face and said: "Young man, there is obviously a problem in the equipment processing link, why do you blame the production line control system?
Haas's equipment handles processing procedures independently. After the processing is completed, the finished product transfer process is the scope of the production line control system."
After criticizing Du Qiu, he turned to Ning Yuze and said: "Chairman Ning, I am sure it is a fault with the equipment itself. Please allow me to repair it."
Seeing Ning Yuze looking at him, Du Qiu said calmly: "Okay, let's ask Dr. Ye to come first."
