Qu Sen's suggestion was definitely a "life-saving medicine". An Yue was also an impatient person. She finished writing the two applications in the command vehicle.
The next morning, she went to Director Ni's office and urged him to give the applications to Cheng Wanqi before the daily meeting of the leadership group.
Working Group 715 had always been very efficient. That morning, they contacted the production unit of the mobile communication relay station through the department.
After the initial communication, they sent the design drawings of the police mobile command vehicle to them and asked them to "feel the pulse".
In the afternoon, Professor Wu was also asked to come out from the communication team.
This was because to solve the signal interference problem, they did not only need to think of a way to solve the signal interference problem. The performance of the filtering plug-in software also needed to keep up. When Professor Wu came out, he brought his two students, Zhou Li and Li Ying, with him.
The drones were part of the integrated function of the command vehicle. The four drones that Qu Sen and the drone design team currently had were also included in the comprehensive test.
The signal interference and radio wave interference of the police command vehicle could be said to be very serious. When the video signal of the "Sky Eye" system was introduced, it affected almost all of the vehicle's equipment, whether it was wired or wireless.
Although Qu Sen had a basic knowledge of circuits and signal science, he was still confused when faced with such a complicated problem.
Professor Wu was very calm. He asked the technician to turn off all of the equipment in the vehicle. Then, he started two tests and two tests. When he encountered interference problems, he asked Zhou Li and Li Ying to record the characteristics of the interference. After one round, three tests were combined into a group and the test was started.
After the test was done, he found a piece of white paper and drew the layout of the antenna groups on the roof. He then took out another piece of white paper and drew the layout of the power and data cables in the car according to the design drawings. He also marked the generator separately.
Finally, he placed the two drawings in front of everyone. He held a pen in his hand and explained the causes of different interference waves to everyone. He also made the connection between the different nodes on the drawings.
In about three hours, the complicated electric surges and radio wave interference that the command vehicle faced while it was working were thoroughly dissected.
The final conclusion was that the overall layout and route had to be completely redone. In addition, there was also a need to install targeted shielding walls at key locations.
Looking at Professor Wu's sketch, An Yue and the other designers were grateful for his help.
Although they considered signal shielding and mutual interference when making the overall design, after all, they lacked experience in the joint use of composite antennas and the mutual interference of multiple signal sources.
In the beginning, because the command vehicle's functions were relatively simple, there was plenty of space between the equipment, and the wiring was also relatively simple. Interference problems were not obvious after simple signal shielding and software filtering.
After the functions were further increased, the layout became more concentrated. The Police Uniform Bureau did not have the experience of integrating so many electronic devices into a single container.
After the test vehicle was driven back and the various systems and software were installed, problems suddenly appeared.
Since Team Leader Ni of the equipment innovation group did not have a seat and the van was not tall enough, he had to bend over and watch Professor Wu the whole time.
After he finished, he held onto Professor Wu's watch and said gratefully, "Thank you, Professor Wu. Thank you so much!"
"Why are you being so polite? I've only just figured out the general problem. How to solve the problem is the difficult part. "
After Professor Wu said that, he pointed at Zhou Li and Li Ying and said, "Let them help you for two days. These two girls have been learning from me for more than two years. They have a solid foundation in signal science. Also, they are software engineers. You guys can use them. "
"I was waiting for you to say that!"
Team Leader Ni knew that it was already good enough for an expert like Professor Wu to come in person. It was basically impossible for him to stay and help. He had been thinking about Zhou Li and Li Ying for a long time.
However, before Team Leader Ni could say anything, Professor Wu said it himself. He was so happy that he could not help but say a bunch of words of gratitude.
Team Leader Ni used the shortest amount of time to finalize the plan. Then, he dragged Professor Wu out of the car and said, "Let's go and eat first. Everyone must be hungry."
Team Leader Ni obviously did not understand Professor Wu's work style. He originally wanted to find a restaurant to treat everyone to a good meal, but he was rejected by Professor Wu.
In the end, the group of people only had a simple meal in the equipment innovation group's cafeteria. Then, Professor Wu took his two students back.
Although Professor Wu had temporarily assigned Zhou Li and Li Ying to the command vehicle design group to help, the two were still members of the military drone testing group. Therefore, the temporary loan still required an official application from Working Group 715.
The next day, the application was approved. The testing group agreed to loan Zhou Li and Li Ying to the police command vehicle design group for a week.
Qu Sen was even happier than An Yue when the application was approved. He personally drove to the communication group to pick up the two girls. After the testing group made fun of him, he successfully picked up the two girls, who had already changed into casual clothes.
An Yue seemed to be very worried that Qu Sen would take the two girls away after picking them up. She was basically "monitoring" the whole time. Qu Sen's car appeared at the equipment innovation group's station. People immediately came out to greet him.
They had already built a one-to-one model of the van overnight. When Zhou Li and Li Ying arrived, they were going to immediately dismantle the equipment on the command vehicle. They were going to do layout adjustments and redesign the entire vehicle.
When the group of designers saw Qu Sen's car arrive, they rolled up their sleeves and picked up their tools. They were ready to start.
However, before they could start, Gao Sheng called An Yue's phone. After a period of monitoring, he seriously suspected that Wu Entai was using a satellite phone to communicate with the outside world.
After making this judgment, the first thing he thought of was the new integrated function of the command vehicle. He knew that the test vehicle was going to be dismantled, so he called An Yue and asked her to stop for a while. He immediately applied for the transfer.
The application was approved in the afternoon. However, the detection range of the test vehicle was limited, and it was too eye-catching. After some consideration. He decided to borrow a communication maintenance vehicle from the mobile company and temporarily install the detection equipment on it.
The communication maintenance vehicle was in place after an hour, and the installation of the equipment began. Everyone worked together to dismantle the equipment from the command vehicle. Just as they were about to continue dismantling the special antenna on the roof, Section Chief Lan of the National Security Department appeared with two policemen.
The purpose of their visit was very simple. They were looking for Qu Sen, Zhou Li, and Li Ying. They hoped that the three of them would cooperate. As for the work target, needless to say, it was naturally Zhang Yuanzhi, who was mentioned last time.
For researchers like Zhang Yuanzhi, who had participated in key confidential projects, even if they were transferred, they had to implement strict confidentiality rules.
This confidentiality requirement involved many aspects. In addition to the basic discipline, it also included a series of detailed requirements such as the duration of the confidential project and the exit report within the confidential project period.
At this stage, there was a huge shortage of software professionals in the country. Therefore, after Zhang Yuanzhi transferred, the local government didn't need to worry about his job placement at all. Several companies and units in the software development field had offered him very high salaries.
However, Zhang Yuanzhi did not choose any of them. Instead, he chose to give up on the job placement and asked for an extra transfer fee.
After returning to his hometown, he registered his household registration. After waiting for his ID card, he did not stay for more than a day. He asked for a sum of money from his parents and brought the total of 300,000 yuan to Huacheng to register a software company.
To be honest, it was a little tight to start a company with 300,000 yuan. After Zhang Yuanzhi arrived in Huacheng, he first looked around for an office building. When he realized that he could not afford the rent, he ran to the suburbs and rented a small shop.
Then, he went to the talent market and recruited a few fresh university graduates. After careful planning, he finally set up the company.
After completing the registration, he gritted his teeth and paid to advertise on the Internet. His main business was software development and web page production.
In Zhang Yuanzhi's mind, he had enough skills and experience. As long as he received a few small jobs in the beginning and did them well, it would be easy for him to make a name for himself. However, the reality was a little cruel.
Zhang Yuanzhi thought that doing business was too simple. There were many small jobs like designing web pages. However, this kind of job could be done by any studio or even an individual.
As long as they had a computer, they could do it at home. The cost of all aspects was not something that Zhang Yuanzhi, who rented a shop and hired a few employees, could compare with.
In terms of software development, small software companies also had studios as obstacles. For large software development, the client first needed the software development company's hard power and past cases.
For someone like Zhang Yuanzhi, who was just a big worker with a few student soldiers, most clients wouldn't even bother to look at him. For small companies that wanted to make it cheap, they could not give much money but had many requests. After the work was done, they would use all kinds of excuses to delay the final payment.
Zhang Yuanzhi was a science student, so he could only focus on technology. He knew nothing about running a business and wrangling with investors. The company lasted for less than half a year before it was on the verge of bankruptcy.
Under the serious situation of not being able to make money, Zhang Yuanzhi, who could not support it, could only close the company and dismiss the few employees. It did not matter if he only had a salary. The young man who wanted to learn technology from him rented a house and started a studio.
In the past few months, Zhang Yuanzhi had some understanding of the local software development, web page production, and server maintenance industry. In addition, his skills were indeed strong.
After throwing away the big burden of the company, he took his only helper and took on work online or subcontracted projects from big companies. His life was much better.
After more than two months, as the business increased, he also earned some money. Not only did the studio change to a bigger house, but he also recruited two of his old employees who were good with technology.
The studio with a total of four people did very well.
It was said that good wine did not fear deep alleys. As long as the work was solid, there was no need to be afraid of not being able to make a name for oneself. As Zhang Yuanzhi's studio became more and more prominent in the industry, someone finally took the initiative to come to the door and ask for cooperation.
The cooperation talks went very smoothly. Half a month later, Zhang Yuanzhi rented half a floor of the office building with the best hardware and location in Huacheng as the new company's office. At the same time, the recruitment work was also going on at the same time.
Moreover, as soon as the company officially started operations, the investors pulled in two big orders.
