Chapter 3536 Surveillance Vehicle

"You don't have to say it." Fan Keqin said, "Then I will go to your office to find you at two o'clock in the afternoon."

It's two o'clock, it's two o'clock, these people from the Security Bureau are still very punctual. When Fan Keqin arrived and found Dong Huayi, the latter took him directly to the backyard. There was actually a car here, which looked like a prison van. The front of the car was connected to the carriage at the back. There are only one window on the left and right in the front, and the rest are all closed. At the end were the double doors, which were also opened at this time. Fan Keqin saw a circle of shelves inside, and on the shelves were a circle of things that looked like radio stations. There were at least three people sitting in the open space in the middle, responsible for playing with the instruments above.

Dong Huayi came closer and asked inside, "How's it going? Has the debugging been successful?"

"There's basically no problem." A man in a shirt replied: "I'll make some fine-tuning during the experiment today, and I think it'll be fine."

"Very good." Dong Huayi said, "Come on, it's a small place inside. You guys come down first and I'll show Director Fan and the others."

"Yes." Several people inside walked out, and Dong Huayi walked up with Fan Keqin, Hua Zhang, Zhang Zhikai, and Liu Xiaoliang. There is really not much space to move around in this car. After just a few of them entered, there was basically not much space left. But it's okay, turning around and so on is quite easy.

Fan Keqin looked at the surrounding instruments and said, "This thing looks no different from a radio station."

"Aren't you a layman?" Dong Huayi pointed to the antenna erected in the corner and said, "You saw it outside, right? This is the antenna. Then come in and connect to these devices. As long as a signal is captured, these devices , you can start working. Don't tell me, it's really no different from the working principle of the radio. Do you see the two headphones on the left and right?" He pointed to the left one and continued: "This. It's normal monitoring." Then he pointed to the right and said: "This is to capture the strength of the signal. If the signal is strong, the sound in his earphones will naturally become smaller. , the closer you are to the captured radio signal, the louder the buzzing in the headset will be, and in the end it will even be a very sharp sound. On the contrary, it will be very low and rustling.”

Dong Huayi pointed with his hand to the position closest to the front of the car and said: "This is the commander. He will constantly use this loudspeaker to notify the cab and adjust the driving direction according to the signals given to him by the supervisor. ”

Fan Keqin, Hua Zhang, and Zhang Zhikai looked over. Sure enough, there is a glass in the frontmost position, and the height of this seat is higher. People sitting on it can observe the road conditions in front of the car's windshield. There is a copper, trumpet-shaped receiver almost at the mouth, and through the copper tube, you can communicate with the cab in front.

Fan Keqin said: "Well, I understand. It means making full use of the mobility of the vehicle and actively looking for the signal source. When you listen to the earphones and scream, it means you have arrived near the signal source."

"Yes." Dong Huayi said: "I have a strong understanding, that's what I mean. Then they all arrived near the signal source. Didn't you drive to follow? After receiving the notice from our surveillance vehicle, we immediately blocked it and started the search. That’s it.”

"Yeah." Fan Keqin said, "That's pretty good." Then he looked at Hua Zhang and Zhang Zhikai and said, "How about it? From now on, your special division and the detective office will be responsible for this matter."

Hua Zhang said: "That's good. Thank you, Director Dong, for giving us credit in the future."

"Hahaha." Dong Huayi laughed and said: "We are all our own people, as we should. Let's agree that as long as you see the surveillance vehicle completely stopped, it is the place. You also get out of the car and start the blockade. , Just search and arrest them." Zhang Zhikai also smiled and said: "Okay, let's see where those secret radio stations are going now. Director Dong, if we get a few more of these cars, we can't do it at a fast pace. of."

"What are you thinking about?" Dong Huayi said cheerfully, "I had to work so hard to install such a machine. Even if I'm thinking too much, there must be something for me to put together."

"Ah, it's just one car." Zhang Zhikai said with a little regret, "That's okay. Then maybe the brothers from the Telecommunications Department should stop being idle every day and wander around more. Let's work a shift back and forth."

"That's nonsense again." Dong Huayi said, "You can work shifts. This thing consumes so much power. Didn't you see that in this room, in addition to the surveillance equipment, there are also shelves on top and bottom, ah ? It's all about the battery. It can run at normal power for five hours... There's nothing you can do about it. The battery capacity is there, and it's so full that you have to come back and replace it. This is the only way.

Fan Keqin said: "This is good. In the past, I didn't know how to deal with it. Hey, if this thing is combined with more lateral points, wouldn't the effect be better?"

Dong Huayi said: "Theoretically this is certainly the case, but in practice it doesn't work. Multiple lateral points must be calculated immediately, and it is very slow. By the time the calculation is completed, the surveillance vehicle will be at the location, so it will be useless."

Fan Keqin said: "Then what are the arrangements for today? Is this considered good? Then let's just drive out for a walk?"

"Wait a minute." Dong Huayi said, "I asked people to take a few radio stations to a few places in the city and asked them not to tell anyone. I'll call you when it's over. I'll use this surveillance vehicle. Let’s give it a try.”

Just as he was talking, a man ran out from the back door of the main building. He was also from the telecommunications office. He came up, saluted and said, "Virgin, the telecommunications teams you have arranged are ready. I want to ask when they will start."

"Very good." Dong Huayi said: "In order, start with the first group, ten minutes later. Then the second group will be an hour later, and the third group will be two hours later. No need to notify me. Just follow this Time comes."

"Understood." The man said for a moment, then turned around and ran forward again, back to the main building. Dong Huayi looked at Fan Keqin and said, "Get in the car and follow us." After saying that, Dong Huayi got into the co-pilot of the surveillance vehicle himself.

Fan Keqin glanced at Zhang Zhikai and said, "Okay, Hua Zhang can take my car, and you can drive with a few brothers and follow our car. Today is just an experiment, so we don't need so many people."

"Yes." Zhang Zhikai said, turned around and directed everyone to get on the bus. Fan Keqin got into a car with Hua Zhang.
