While Qu Sen and the other two were talking, Section Chief Lan was listening to them carefully. The police officer who came with him was sitting on the side taking notes.
After the three of them finished talking, Chief Lan nodded and asked, "After you guys met at the dock last time, did you guys plan to meet up with Zhang Yuanzhi?"
Qu Sen listened and said, "That day, Zhang Yuanzhi was with a client. We just had dinner, so we only said a few words.
At that time, Zhang Yuanzhi wanted to get Zhou Li's contact information. However, the testing work was confidential, so Zhou Li did not give it to him.
However, these days, Zhang Yuanzhi sent a few invitations to him through the Psychological Intervention Center of the Occupational Disease Hospital. The invitations were conveyed several times. But everyone is busy, so I declined on behalf of Zhou Li. "
"Okay." Chief Lan Ke nodded and asked, "May I ask if Zhang Yuanzhi invited Zhou Li alone or all three of you at the same time?"
"All three of us, including me," replied Qu Sen.
"Okay, that's all for now. Sorry to bother the three of you. If we need any further assistance, we will contact you again, "said Section Chief Lan as he stood up from the sofa.
Qu Sen did not expect the so-called inquiry to be so simple. He was stunned for a moment before he stood up with Zhou Li and Li Ying. They shook hands with Section Chief Lan and sent him and his colleagues away.
"It seems like Zhang Yuanzhi's money is a little hot," muttered Qu Sen as he watched Section Chief Lan's car drive away.
"What does that have to do with us?" replied Zhou Li. He pulled Li Ying and the two girls went into the office building together.
Qu Sen shrugged and went back to Professor Wu's office to continue discussing the thesis.
After eating dinner with the testing group, Qu Sen signaled Zhou Li with his eyes and walked out of the cafeteria. After waiting outside for a while, Zhou Li strolled out unhurriedly.
"Let's go. I'll walk you on the road." There were people around the cafeteria. Qu Sen did not hold Zhou Li's hand. He just used his head to point in the direction of the testing field.
"There's no road for you to walk on in the middle of nowhere." Zhou Li rolled her eyes and said in a bad mood. However, she still followed Qu Sen's footsteps.
The testing area was in the mountains, and the surrounding mountains were the territory of the communication team. ..... The two walked forward for a while and turned onto a path that led to the mountain radar station..
There was no one around, so Qu Sen reached out and held Zhou Li's hand. The two of them strolled slowly on the path side by side.
"Zhang Yuanzhi passed high? Did you ask me out? "After taking a few steps, Zhou Li turned her head and asked. She didn't ask Qu Sen.
"It's us!" Qu Sen corrected first, and then said, "It's been a few times. High? I called your phone but it was always turned off, so I told you to tell me. Why? Are you unhappy that I rejected it for you? "
"Ouch ~ it hurts!"... Lady Zhou pinched the soft flesh on Qu Sen's waist as soon as he finished speaking.
.. Zhou Li vented her anger and said, "Why do you think Zhang Yuanzhi doesn't know how to look at other people's faces at all? I was just being polite. Can't he see it? ".
"You still don't know this." Qu Sen chuckled and muttered. Seeing that he was about to be pinched again, he quickly pretended to be serious and said, "That kind of person has a problem with his brain. Chasing high on this side? Passing high on that side? Asking someone else. I don't know if there's something wrong with his brain or if he's made too much money and doesn't know his own worth. "
Zhou Li did not speak after listening, but her expression showed that she agreed with Qu Sen's statement.
"Hey, do you think that the National Security is targeting him because he sold the things of the Wuyi Group?" Qu Sen lowered his voice and asked.
"Who cares." Zhou Li said indifferently, then frowned and muttered, "A technical cadre like him has to receive security and confidentiality education before leaving the job. He should know better than anyone how confidential the projects we do are. "
"He left his job. He was tempted by society and blinded by money," Qu Sen replied. He felt that the mountain wind was a little cold, so he reached out and put his arm around Zhou Li's shoulder.
The two walked along the mountain path for a while. Zhou Li was embarrassed to leave the sight of her colleagues for too long. After half an hour, she strolled back with Qu Sen.
Almost everyone in the testing group knew about the relationship between Qu Sen and Zhou Li. When they saw the two of them walking back, no one joked around.
Qu Sen looked at the time. It was almost seven o 'clock. He said goodbye to everyone and drove away from the communication group.
"You're back?" Huang An greeted Qu Sen when he arrived at the station.
"Yeah, I asked Professor Wu to help me collect some theses. I came back after dinner," Qu Sen replied.
"Hurry up and give An Yue a call. She called you not long after you left at noon. She just called again."
"Come out from that side. I forgot to turn on my phone," Qu Sen slapped his head.
Phones had to be turned off when entering the communication group. Qu Sen forgot about it when he came out.
He took out his phone and dialed An Yue's number. An Yue answered within two seconds, "Leader An, I'm sorry I'm late. Do you need me for something?"
"Are you busy over there?" An Yue immediately asked.
"Not really. Just tell me what you need."
"The police uniform bureau sent the third version of the command vehicle over. If you're not busy, bring your baby over. Let's test it out."
The mobile command vehicle had been in the process of being upgraded. Compared to the first version, it had undergone three major upgrades.
This upgrade was mainly based on the first two versions. It received technical support from Mobile and Unicom, and added a wireless cellular device.
In addition, it added a satellite communication port and an L-band and K-band scanning function. This meant that not only could it exchange digital information with the command center through the satellite when there was no signal, but it could also capture the signals of other satellite phones in a small area.
"No problem, I'll go over now." Qu Sen's monthly salary included 50 yuan from the equipment innovation group. He just had to ask An Yue and she would definitely get it.
"Brother Huang!" Qu Sen hung up the phone and called out to Huang An, who was watching the students control the drone to fly with precision. Seeing him look at him, Huang An gestured to the phone in his hand and said, "Leader An is asking me to go over."
"Go. By the way, the department is sending a visiting team down …" Huang An waved his hand halfway through his sentence. "Forget it. We'll talk about it later. You go and do your work first."
"Okay!" Qu Sen responded and returned to the drone team. He picked up a suitcase containing the first version of the general reconnaissance drone and returned to the car. After starting the Santana, he turned on his phone and looked at the coordinates An Yue sent over. He set off in that direction.
The testing of the new version of the command vehicle was in the suburbs. They deliberately found an area with poor cell phone signal coverage. When Qu Sen arrived, it was already dark. From afar, he saw a box with a satellite receiver and an antenna on the top of a carriage in the night.
At first glance, Qu Sen thought that it was a battlefield signal relay vehicle parked there.
When Qu Sen found a place to park, the surveillance camera in the car had already seen it. As soon as he approached with the drone, the back door opened.
Using a box as a command vehicle, the space inside was much larger than the previous Iveco. However, most of the space was taken up by various equipment. It could only accommodate up to five operators and commanders.
When Qu Sen arrived at the door, Leader Ni of the equipment innovation team came out. He smiled and patted Qu Sen on the shoulder. "You guys continue. I'm just a layman, so I won't join in the fun."
"Leader Ni, who would dare say that you're a layman!" Qu Sen quickly complimented.
Leader Ni was much older than Huang An. Although he was a technician who studied firearms, he had a very wide range of knowledge.
"I don't know if I'm a layman or not, you brat." Leader Ni lightly punched Qu Sen and said with a glare, "Don't just focus on your little plane all day. I'll be more careful on my side."
"Yes!" Qu Sen smiled and stood at attention.
"Go on, go on, I'm leaving." Leader Ni patted Qu Sen again and walked towards his car.
"See you later, Leader Ni." Qu Sen shouted at Leader Ni and turned to get into the command vehicle.
There were four people in the car. An Yue, two technicians, and Gao Sheng, who they had just met yesterday.
"Hello, Ms. An." Qu Sen first greeted An Yue and then nodded at the two technicians. He sat in the seat reserved for the drone operator and patted Gao Sheng. "Captain Gao Sheng, aren't you busy?"
"No matter how busy I am, I still have to take some time out to see my baby. If I don't hurry up and learn, I won't be able to play with it." Gao Sheng laughed.
The mobile command vehicle was prepared for front-line commanders like Gao Sheng. Therefore, every time it was upgraded, he was always the first to arrive.
"How is it, Ms. An?" Qu Sen said as he opened the case and took out the control laptop and placed it on the console.
"For now, only one mobile and connected signal relay can be activated at the same time. However, the effect is not bad. It basically reached the expected parameters." An Yue said with some regret.
The problem of ideas exceeding the current level of technology was not only encountered by the drone design team, but also by all electronic equipment research teams.
Even the equipment innovation team's police equipment research team had encountered a threshold in material science.
"Let's do a drone interference test?" Qu Sen asked after he started the drone control platform.
"You little brat, all you know is how to play with your stupid plane." An Yue angrily patted Qu Sen before she signaled the two technicians to get ready.
When Gao Sheng heard that they were going to do a drone interference test, he took out the first model of a general reconnaissance drone from the case and skillfully installed the battery. He turned on the power and prepared to release the drone outside the command vehicle …
The comprehensive test lasted until late at night, and the results were very disappointing. After the mobile and connected signal cellular device was activated, the image captured by the drone was greatly affected. Especially the mobile signal, the image interference was very serious.
It was fine when the satellite communication was activated, but when the drone captured the surrounding satellite communication signals, the interference was even more serious. Not to mention the control platform of the drone, the other electronic equipment in the command vehicle also had very serious interference.
"Don't the police equipment department do a test after the installation?" Qu Sen scratched his head and asked.
"They are only responsible for the installation of the hardware according to our design," An Yue said helplessly.
When the multiple antennas of the command vehicle were working at the same time, the radio wave interference between them had always been a big problem in the design. Now, with the addition of signal interference between multiple devices, the multiple sources of interference were entangled together, making it difficult to find a way to deal with it.
"Oh right, Professor Wu from our university is here. We can ask him to help us think of a way.
