Chapter 52 - Waste Utilization
In the 911 Air Base, many tasks can be assisted by highly automated machinery and do not require too much manpower.

After all, compared with the cost of machines, manpower is still quite high most of the time.

Especially with a high degree of education, college students are very expensive nowadays, and no one is willing to let them carry bricks and bags.

All Chen Fei had to do was to follow the instructions, tap the buttons, and push and pull the joystick a few times, and it was done easily.

Although these tasks are very basic and do not have any technical content, several teams in the logistics department can't spare any energy to deal with them at this juncture. The work was handed over to Chen Fei.

For undergraduates who have just graduated, there is no difficulty in getting started, and with a little mention, they can quickly become proficient.

In just a few minutes, Chen Fei finished disposing of the domestic garbage and kitchen waste accumulated for many days. The effect of the biodegradant automatically sprayed in the reaction tank was immediate, and the stench in the air began to fade rapidly. Blowing, basically there is not much smell left.

Under suitable temperature and humidity conditions, biological tissues and plastic components will be completely decomposed by various bacteria and active enzymes within 24 hours, and become a complex organic paste rich in nitrogen, phosphorus, potassium and other compound elements , after dehydration and granulation treatment, it is a ready-made organic fertilizer.

Inorganic materials and metals that cannot be "digested" by the biodegradants are filtered out for further processing.

The work that really consumes a lot of time is dealing with work waste from various departments, especially the expired aviation consumables and out-of-warranty parts of the machine repair team. There are all kinds of mess, mostly metal, plastic, glass and ceramics.

Just like now, rolling all the way from the "hill" to the "small pot" at Chen Fei's feet, it really has everything!

Bending down to pick up this "small pot", holding it in his hands and looking at it, he felt an inexplicable sense of appetite, always wanting to try to take a bite to taste the taste, Chen Fei forcibly suppressed this weird "pica" idea , like "Vision", is a sequela brought by magic potions. There is probably no cure for it, and it has to be overcome by oneself all the time.

It turns out that this rectangular "pot" is neither a hot pot nor a pot for cooking and cooking, but a directional antenna pot for sending and receiving radio signals. From the parameter introduction printed on the back, it supports multiple frequency bands and can The radio signal is projected to a distance of up to fifteen kilometers.

Except for some slightly deformed external metal parts, the antenna pot with a diameter of about [-] centimeters seems to be generally intact, and it may still be usable.

Wanting to give it a try, Chen Fei found more than a dozen wireless AP terminals in a small mountain of garbage. Perhaps the 911 air base is currently undergoing replacement of old equipment, and these old guys are directly transferred from their original posts. Weed it out, and throw it all here waiting to be decomposed and regenerated.

I tried to power on these APs and connect them with my mobile phone, but they were all good and can be used normally.

This is simply too wasteful.

A full man doesn't know a hungry man is hungry, the 911 Air Force base will directly scrap the old AP terminal that can still be used for regeneration, while the fellow teacher Shen Fei has always been disconnected from the communication network as if isolated from the world.

If it can be used again...

Chen Fei's heart skipped a beat, and he didn't hesitate too much when he thought of this, and quickly put it into action.

This pile of waste waiting to be disposed of is actually a small treasure, and there are always some surprising gadgets to be found.

After digging for a while, Chen Fei found another eight antenna pots, hundreds of AP terminals of the same model, a dozen AC controllers, several directional gain antennas of different regulations, more than a dozen omnidirectional general-purpose antennas, several large rolls Optical fiber, a total of thousands of meters of copper core high-speed network cables, more than a dozen pairs of full-duplex photoelectric signal relays, switches replaced with the AP side, some solar panels, and several groups of chemical energy batteries with 60% capacity and life left , DC transformer modules of various specifications, more than a dozen stainless steel boxes, and even a few book-sized mini-computers. It seems that just in time for the 911 air base to upgrade network equipment in batches, such a lot of things have been replaced. .

At any rate, he is a serious undergraduate student, even if he is studying in the Department of Economics, even if he has never eaten pork, he has seen pigs run more or less. Chen Fei is not ignorant of what equipment is needed to set up a home wireless network environment. Just ask the AI, and with some bridging equipment, big things can be done.

Although these things dug out from the garbage dump come from different places and originally had different purposes, but they are pieced together to find the corresponding support protocols, frequency bands, interfaces and electrical standards to form a segmented wireless network. The communication relay network link is limited to civilian use, without too many requirements, and it is not unfeasible.

The logistics department did not object to Chen Fei's idea, but gave some help.

After all, Mr. Shen is a neighbor of the 911 air base, and the two sides often communicate with each other. It is only a small effort to help the neighbors to connect to the Internet. Besides, it is waste recycling, and there is not much extra expenditure.

Instead of scrapping and decomposing these old equipment, it is better to continue to use the waste heat. Naturally, I am very happy.

Borrowing a high-precision contour map near the aircrew base from the control tower, applying for a dedicated public network interface from the communication group, and then using the free time of guarding Target's low-temperature nuclear fusion energy tower on night shifts, Chen Fei was very happy. The layout plan of the wireless relay link was quickly planned, and some equipment was assembled.

He plans to set up a set of signal relays every eight kilometers between the 911 air base and the mountain primary school. Two directional antenna pots are responsible for listening to radio signals in different directions. Source, chemical battery energy storage, capacitor battery as backup redundancy, a full charge can continue to work for a week, enough to cope with extreme weather.

The highest bandwidth of the entire relay network link can reach 6742Mbps. Taking into account interference and loss, at least [-]% to [-]% of the stable bandwidth can be reserved, and the signal delay is not too exaggerated, which is completely enough for use, even in rainy and snowy weather It won't have much impact.

On the rare rest day, Chen Fei started to do it himself.

An outdoor optical fiber was pulled out from the gate of the 911 air crew base. Along the way, a hand drill was used to drill holes in the rock, and pitons were inserted to fix the optical fiber. Three recycled metal pipes and foam cement were used until five kilometers away from the base. Build the first relay station.

The transmitting power of the active antenna pot is 3W, leaving enough redundancy for weather interference, and the WIFI antenna of the AP side can cover the network signal within a radius of 500 meters outdoors.

From the 911 air base to the mountain primary school where Mr. Shen Fei works, the walking distance is about 21 kilometers. One optical fiber saves 5 kilometers when going out, and only three relay stations are needed for the remaining 16 kilometers.

It doesn't take much time to build the relay station, and it can be done in less than half an hour, because many tasks have been prepared by Chen Fei in his spare time.

The most time-consuming thing is still transporting equipment along the ridge.

There were two trips back and forth on the way, and it wasn't until the sun was setting that Chen Fei pushed the wheelbarrow and arrived at the location of the last relay station.

In the yard of Teacher Shen Fei's school, dogs barked one after another, and the two dogs "Amao" and "Ahu" kept barking.

Approaching the school where the barking stopped abruptly and there was no more movement, Chen Fei shouted loudly, "Mr. Shen, it's me!"

He knew very well that the reason why the two dogs suddenly kept barking was because he had just projected a positioning and guiding laser beam to the school at the second relay station to alarm them.

Although dogs can only distinguish a few colors, they can still be keenly aware of abnormal bright spots.

The distance between the relay station and the school is closer than planned, only about 6.7 kilometers, which means the signal will be stronger and more stable.

"Huh? Chen Fei, it's you! I was really shocked, students, it's okay!"

Shen Fei's head protruded from behind the courtyard wall with a muzzle. When he saw that it was Chen Fei pushing a wheelbarrow, he breathed a sigh of relief.
