"If it is done in this way, it should be able to directly lock the control signal, but the control method of this monitoring device has to be finalized."

Luo Hao looked at a small device in his hand, then raised his head and thought for a while, then looked at the control signal capture program in the computer, started the program directly, then connected to the device in his hand, and began to search for control signals.

According to Luo Hao's design, the current control signal capture program can directly control the device that Luo Hao made just now to directly capture control signals with specific rules.

After all, this kind of signal is basically a repetitive command sent, and it will also regularly send high-frequency return signals to send the current information of the device back to the controller. This has certain characteristics, allowing Luo Hao to send this kind of special signals are identified.

As for the control signal catcher in his hand, it is a small tool specially modified on the basis of the signal catcher.It is also possible to check and capture signals such as infrared signals by connecting auxiliary devices such as infrared sensors.

After Luo Hao started the computer program and connected the device, not long after, some control signal fluctuations appeared on Luo Hao's computer screen, and there were quite a few.After all, part of the previous detection team was moving things outside, and the control signals of this part of the detection team were also captured by Luo Hao.

Luo Hao stared at the computer screen, watching the ever-changing signal fluctuations, without blinking his eyes.

Soon, a short signal wave suddenly appeared, and then another signal wave of the same frequency band appeared.Luo Hao's eyes lit up: "This signal looks suspicious, doesn't it? It doesn't belong to the same frequency band as the control signal of the detection robot I made, and there are only two short signals that come and go, which conform to the basic characteristics of the control signal. "

"Crack the signal first!" Luo Hao clicked the mouse to select the signal wave detected just now, and began to use the program to crack the content.

Soon, the content of this simple control signal was deciphered by Luo Hao.

"It should be this. Except for the up, down, left, and right directions, there is no other control information." Luo Hao rubbed his chin. "The next step is to detect the source of this signal."

"It's a good thing that the control signal is not sent through crystal resonance, otherwise it would be really difficult to find the source of the signal." Luo Hao muttered while operating on the computer again.

The controller of the equipment should not be close to here. In addition to the attenuation caused by various obstacles, the signal strength of each location is different. As long as the attenuation of the signal is detected, it is possible to find the source of the control signal.

This situation is different from the situation of directly hacking into satellites. Satellite signal waves generally have many different contents. As long as the electromagnetic wave signals can be converted into understandable language, the attribution of satellite signals can generally be determined, and even some satellite signals contain It will also contain information such as the mailing address of the receiving target.

But the remote control devices are different. Basically, many remote control devices can only transmit simple commands. Luo Hao, who has been busy for a while, has people place different remote control signal capture devices around the martial law area.

These devices are located far apart so that the location of the signal source can be determined by the slight time difference when the signal is captured.

During the installation of the sensor, Luo Hao was still staring at the computer screen in front of him, trying to find out if there were any other suspicious signals.

Not long after, a different signal appeared on Luo Hao's computer screen, but this time it lasted longer, and it disappeared after about a minute or two.

Luo Hao's eyes lit up, and he quickly deciphered the signal.

"Sure enough, there is no problem with the previous guess. There are not many images of this device stored locally, and they are all uploaded directly." Luo Hao looked at the restored video clips and some photos in front of him, and smiled slightly.

"With these photos that still have time watermarks, it will be much easier to find this monitoring device!" Luo Hao rolled his eyes, and after setting the program to automatically detect signals, he got busy on the test bench again.

On the Internet, the dispute between Xia Guo and Meiguo has become more serious, and more and more statements have been issued between the two foreign ministries.It made people feel a little strange for a while, whether this is a formal negotiation between the two countries or a child is arguing.

In the capital of Xia Kingdom, in the office building of the government.

"Is there any news from Shennongjia? Have you found the person who took the sneak shot?" Elder Zhou asked calmly.

"Not yet, but Luo Hao has already started to move, and it should take some time." Secretary Cui replied, "According to Luo Hao's speculation, this monitoring device is probably only the size of an ant, and it will be really hard to find it in a while. "

"A monitoring device the size of an ant?" Mr. Zhou was taken aback, "How small is our smallest monitoring device?"

"I heard people from the Weapons Research Institute say that it is about the size of a dragonfly?" Secretary Cui thought for a while and replied, "It is said that Dean Jin was inspired by something before and successfully developed it."

"It's the size of an ant. It's hard to find it by manpower. If this thing can burrow into the ground, it will be even more difficult to find!" Mr. Zhou sighed, "Is there any backup plan over there?"

"It's already planned to lay the ground there, and the latest jamming equipment has already started to be delivered." Secretary Cui said, "If Luo Hao can't solve this problem in a short time, then first surround the site with signal jammers for a week, inside and outside. Just disconnect it."

"But in this way, our normal communication will also be affected." Elder Zhou sighed and said, "Also, send a message to the military department and let them pay attention to vigilance during this time. What a small move!"

"Old Luo and the deputy commander have already made arrangements." Secretary Cui nodded, and asked worriedly, "Will the beautiful Congress use this reason to force entry?"

"Probably not, this reason is not strong enough, after all, they have not seen the actual benefits!" Mr. Zhou shook his head, "There is no actual benefit that can be seen, and it is impossible for the beautiful country to pay too much to do so But, if one day, they discover that there is some technology in this ruin that makes them jealous, as long as the value is higher than the price they paid, the beautiful country will definitely do it!"

"So we have to get ready!" Elder Zhou looked at Secretary Cui, "When the matter in Shennongjia is almost settled, call Luo Hao back!"
