I was a special forces soldier in the soldier assault

Chapter 91 Relay station erection for beginners (seeking subscription monthly pass)
The training camp has officially started. Although the weather is still cloudy, there is no rain today, so it is more suitable for training.

Chen Dong and Mao Jianxun worked together to move out all the supporting equipment for the relay station. Since the equipment was relatively heavy, they had to work together.

After the equipment was brought out, Mao Jianxun briefly introduced the characteristics of the relay station. He pointed to the pile of equipment and said: "The so-called relay troops are a type of communication soldiers. This specialty is the same as that of every communication unit. , is an indispensable one in modern warfare."

"In ancient my country, the communication tools for commanding the army to fight included flags, drums, horns, gold, etc., and there were personnel who were specially in charge of beating drums, ringing gold, waving flags, and sending orders. There were also communication facilities such as beacon towers and post stations. Smoke, fire, drums, fast horses, etc. communicate over long distances by way of relay.”

"With the development of the telecommunications industry, telecommunications equipment has gradually become available in the army, and a telecommunications unit has also been established."

Chen Dong nodded frequently as he listened. These materials were introduced in detail on the front page of the Signal Corps Manual, so he was naturally very clear.

Mao Jianxun also knew that Chen Dong would definitely be able to understand, so he just briefly described it, and then said: "So, the role of relay soldiers is like ancient beacon towers and post stations, and their main function is long-distance communication."

"Although wired soldiers can effectively protect against communication eavesdropping on the battlefield, their distance is limited by humans, so they are generally not deployed too far away. And the relay equipment in front of you is the best long-distance communication equipment."

After speaking, he walked to a wooden box, and took out a rectangular iron box from it. After opening the lid, there were dense line interfaces on it, which were exactly the same as the interfaces on the field phones used by wired soldiers.

The only difference is that there is only one interface button for answering calls on the field phone, but there are at least a dozen or twenty interfaces on this tin box.

"You can see what this device does!"

Mao Jianxun asked casually.

Chen Dong seemed to have figured something out, and then pointed and asked: "Report teacher, is this iron box the same function as the field phone used by our wired soldiers, and it is used to connect the call line."

"Don't open your mouth and shut your mouth on the tin box, it's called a junction box."

Mao Jianxun was a little more humane than Zheng Jiapeng, and even rolled his eyes.

Chen Dong touched his head in embarrassment, and pouted.Mao Jianxun continued: "You are right. The function of this junction box is to connect the call line."

"I'm sure you know that when the wired soldiers set up a communication line, they need a squad to dispatch, and the distance to set up is only about ten kilometers."

"Even if multiple teams work together to set up the line, although the line can be set up, it is time-consuming and laborious."

"And this junction box is very useful!"

"You should know that there are two shifts in the relay station. It is useless to set up one alone, so there are also two junction boxes. One of the functions of the relay station is to omit your maintenance in 2.3.4 and so on. post."

Chen Dong greeted the first question and raised his hand as a signal. After Mao Jianxun nodded, he asked again: "Teacher, what does it mean that the maintenance whistle can be omitted in the middle? I didn't understand."

Mao Jianxun did not answer, but turned around and opened all the remaining boxes, then squatted on the ground, pointed to each wooden box and said: "These equipment have a unified name, that is, radio microwave relay machine."

"The relay we commonly use at present has dual capabilities of frequency hopping communication and spread spectrum communication, and these two communication methods have good anti-interference and concealment, and can play the role of emergency communication in wartime."

Mao Jianxun inserted the plug at one end of the distribution box into another machine in the box, and then explained: "This is a switch. The plug of the distribution box needs to be connected to it to work, and the switch needs to be connected to the host."

He turned his finger to the machine in another wooden box and said.

Then he took out a bundle of double lines and two field phones from the side.

I saw that Mao Jianxun picked up two quilt double threads with wire cutters. They were not long, and the average length of each thread was about one meter.

He opened the two ends of the wire a little, exposing the copper wire in it, and then connected the two ends separately.

One end is connected under the communication button of the field phone, and the other end is connected under one of the communication buttons of the junction box.

Then turned to another set of equipment, and also took out a junction box from the wooden box. The distance between the two junction boxes was five meters wide.

In the same way, another line is connected to the field phone, and the other end of the line is connected to the communication button of the junction box.

Mao Jianxun walked between the two and said, "Do you understand now?"

Chen Dong looked at the layout and instantly understood the mystery: "This... a combination of wired and wireless?"

"Haha, that's a good sentence!"

Mao Jianxun praised, with a smile on his face: "From another perspective, the relay station can indeed be regarded as a combination of wired and wireless communications."

"The relay station transmits signals with frequency hopping through equipment and relay poles. Take your artillery unit as an example. In war, you only need to set up a relay machine at the artillery position and observation post, and then your wired soldiers directly connect the line to the relay Stand on the junction box."

"In this way, it saves time and effort. There are many communication interfaces on the junction box, and multiple phones can be connected at the same time."

"In addition to the junction box, there are many interfaces on the switch, which can be added with junction boxes. In theory, as long as the battlefield needs it, it is no problem to connect dozens or hundreds of phones at the same time."

"What's more important is that the relay can also transmit video signals, which can achieve video communication between the two places, synchronize sound and video, and have good confidentiality."

"So learning the skills of relay station erection is also very helpful for improving the combat effectiveness of troops."

Chen Dong listened to teacher Mao Jianxun's careful explanation, and the more he listened, the more he felt the importance of relay soldiers. This is really a high-tech equipment.

Thinking back to the cheap equipment he used when he had wired soldiers, Chen Dongdou felt embarrassed to face Li Dazhuang in the future.

But the ensuing questions forced Chen Dong to raise his hand again and ask: "Teacher, since the relay station is so powerful, why don't all of them use this communication method, is it better?"

As soon as he finished speaking, Chen Dong regretted it, and just blurted out without thinking about it.

Sure enough, after listening to it, Mao Jianxun directly criticized: "Are you really confused or just pretending!"

"There must be multiple means of communication on the battlefield. Even if one of them is compromised, normal communication can be guaranteed."

"Besides, a set of equipment for the relay station is very expensive, and the cost for the entire army to use it is too high, so you don't have to think about it."

"Hey, I was wrong, I just asked the question without thinking too much!"

Chen Dong played sloppy eyes. No. [-] teacher Zheng Jiapeng was not there, and there were no other leaders around. Mao Jianxun was not too harsh. He waved his hand and said, "Forget it, I'll let you off this time."

"Come here, I will start teaching you the installation of each device now,"

"Yes!"

Chen Dong followed and squatted on the ground, and began to listen carefully.
