At the 911 Air Service Base, many tasks are assisted by highly automated machinery and do not require much manpower.
After all, compared to machine costs, manpower is quite high most of the time.
Especially those with high education. Nowadays, college students are very valuable. No one is willing to let them carry bricks and carry big bags.
All Chen Fei had to do was follow the instructions, click the buttons, and push and pull the joystick a few times, and he could easily get it done.
Although these tasks are very basic and do not have any technical content, several teams in the logistics department are completely unable to spare the energy to deal with them at this juncture. Everyone is working overtime and busy sorting out the container materials, which can just be simple.
The work was handed over to Chen Fei.
For freshly graduated undergraduate students, it is not difficult to get started. With a little help, you can quickly become proficient.
In just a few minutes, Chen Fei finished processing the domestic waste and kitchen waste that had accumulated for many days. The biodegradant automatically sprayed in the reaction tank had an immediate effect, and the odor that filled the air began to fade quickly, and then was blown away by the wind.
After blowing, there is basically not much odor left.
Under appropriate temperature and humidity conditions, within 24 hours at most, biological tissues and plastic components will be completely decomposed by various bacteria and active enzymes, turning into a complex organic matter paste rich in nitrogen, phosphorus, potassium and other chemical elements.
, after dehydration and granulation, it is ready-made organic fertilizer.
Inorganic materials and metals that cannot be "digested" by biodegradants will be filtered out and processed separately.
The work that really takes a lot of time is to deal with the work waste from various departments, especially the failed aviation consumables and over-warranty parts from the maintenance team. There are all kinds of mess, mostly metal, plastic, glass and ceramics.
Just like now, from the "hill" to the "small pot" at Chen Fei's feet, there is really everything!
He bent down to pick up this "small pot" and looked at it in his hand. He felt an inexplicable sense of appetite and always wanted to take a bite to taste the taste. Chen Fei suppressed this weird "pica" thought forcibly.
, like "vision", are all sequelae caused by magic potions. It is estimated that there is no cure, and you have to overcome yourself all the time.
It turns out that this rectangular "pot" is neither a hot pot nor a cooking pot, but a directional antenna pot for sending and receiving radio signals. Judging from the parameter introduction printed on the back, it supports multiple frequency bands and can
Radio signals are projected to distances of up to fifteen kilometers.
Except for some slight deformation of some external metal parts, the antenna pot, which is about 30 centimeters in diameter, looks generally intact and may still be usable.
Thinking of giving it a try, Chen Fei found more than a dozen wireless AP terminals in a hill-like garbage dump. Perhaps the 911 air service base was replacing old equipment recently, and these old guys were directly removed from their original posts.
Eliminate them and leave them all here waiting to be decomposed and regenerated.
I tried to power on these ap terminals and connected them with my mobile phone. They were all good and can be used normally.
This is simply such a waste.
A man who is full does not know that a man who is hungry is hungry. The 911 air service base directly scrapped the old AP terminals that were still usable and regenerated them. However, fellow teacher Shen Fei's place had always been disconnected from the communication network as if it were isolated from the rest of the world.
If it could be used again...
Chen Fei's heart suddenly moved, and he quickly took action without much hesitation when he thought of this.
This pile of waste waiting to be disposed of is actually a small treasure, and you can always find some surprising gadgets.
After digging for a while, Chen Fei found eight more antenna pots, hundreds of ap terminals of the same model, a dozen ac controllers, several directional gain antennas with different regulations, a dozen omnidirectional general-purpose antennas, and several large rolls. Optical fibers, 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 that were replaced together with the AP end, some solar panels, and several sets of chemical energy batteries with 60% of their capacity and life left. , DC transformer modules of various specifications, a dozen stainless steel boxes, and even a few book-sized mini computers. It seems that just in time for the 911 air service base to upgrade network equipment in batches, such a lot of things were replaced. .
After all, he is a serious undergraduate student. Even if he studies in the Department of Economics, even if he has never eaten pork, he has seen pigs running around. Chen Fei does not know anything about what equipment is needed to build a home wireless network environment. With Juewen AI and some bridging equipment, big things can happen.
Although these things unearthed from the garbage dump came from different places and originally had different uses, they were pieced together to find the corresponding support protocols, frequency bands, interfaces and electrical standards to form a segmented wireless Communication relay network links are limited to civilian use, do not have many requirements, and are not impossible.
The Logistics Department did not object to Chen Fei's idea, but instead gave him some help.
After all, Teacher Shen is a neighbor of the 911 Air Service Base, and the two parties often communicate with each other. Helping the neighbors to connect to the Internet is just a little effort, and besides, it is still recycling waste, and there is not much extra expense.
Rather than scrapping and decomposing these old equipment, it would be better to continue to use the waste heat, which is naturally very happy.
Borrowing a high-precision contour map of the vicinity of the aircrew base from the tower, applying for a dedicated public network interface from the communications team, and then using his free time on the night shift at Target's low-temperature nuclear fusion energy tower, Chen Fei was very The layout plan for the wireless relay links was quickly planned, and some equipment was assembled.
He plans to build a set of signal relays every eight kilometers between the 911 aircrew base and the mountain primary school. Two directional antenna pots are responsible for listening to and receiving radio signals in different directions. The communication AP will convert and amplify the signals, using solar energy as power. Source, chemical battery energy storage, capacitor battery for backup redundancy, a full charge can last for a week, enough to cope with extreme weather.
This chapter is not finished yet. Please click on the next page to continue reading the exciting content! The maximum bandwidth of the entire relay network link can reach 6742mbps. Taking into account interference and loss, at least 40% to 50% of stable bandwidth can be retained, and the signal delay is also reduced. It’s not too exaggerated, it’s completely sufficient for use, and it won’t have much impact even in rainy or snowy weather.
On a rare day off, Chen Fei started to do it himself.
An outdoor optical fiber was pulled out from the gate of the 911 aircrew base. Along the way, holes were drilled in the rocks with hand drills, pitons were inserted, and the optical fiber was fixed. Three recycled metal pipes and foam cement were used until the location was five kilometers away from the base. The first relay station was built.
The transmitting power of the active antenna pot is 3W, which leaves enough redundancy for climate interference. There is also the AP end's own wifi antenna, which can cover outdoor network signals within a radius of 500 meters.
The walking distance from the 911 aircrew base to the mountainous primary school where Teacher Shen Fei works is about 21 kilometers. One fiber optic cable saves 5 kilometers, and only three relay stations are needed for the remaining 16 kilometers.
It doesn't take much time to build the relay station. It can be done in less than half an hour, because Chen Fei has done a lot of work in his spare time.
What takes the most time is transporting equipment along the ridge.
After two round trips, it wasn't until the sun set that Chen Fei pushed the wheelbarrow to the location of the last relay station.
In the courtyard of Teacher Shen Fei's school, dogs barked one after another. The two dogs "Amao" and "Ahu" were barking non-stop.
Approaching the school where the barking suddenly stopped and there was no movement, Chen Fei shouted loudly: "Teacher Shen, it's me!"
He knew very well that the reason why the two dogs kept barking suddenly was because he had just projected a positioning guidance laser beam at the school at the second relay station and alerted them.
Although dogs can only distinguish a few colors, they can still be keenly aware of abnormally 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.
Shen Fei's head and the muzzle of a gun popped out from behind the courtyard wall. When he saw it was Chen Fei, pushing a wheelbarrow, he immediately breathed a sigh of relief.
