The project of building residences for the travelers also started. Compared with the previous infrastructure construction, this project was much simpler. The simple houses were constructed with standard parts like building blocks, so the construction was not difficult. 【Read full text】
The foundation of the residential area has been appropriately raised by 2 meters, firstly, to prevent possible flooding, and secondly, in case of attack, it can resist from a high position. The entire slope of the foundation is paved with stones, and the ground is hardened. The simple houses adopt the row layout common in new villages. All houses are arranged in the same north-south direction and are arranged into seven groups around the central square. They are numbered clockwise with Arabic numerals. Groups 1 to 5 are single dormitories for men. Six groups are women's single dormitories, and seven and two groups are family units. Each single dormitory accommodates 4 people, while families have one dormitory each. According to past ideas, the simple room is equipped with a comfortable environment as much as possible, and is equipped with lights and power sockets. However, there is no furniture - the wood currently has to be given priority to infrastructure projects - even so, many people are happy. , I can sleep in a real house for the first time in more than ten days, my laptop can be charged again, and my night life is no longer boring...
Rows of clothes drying racks are set up in the square of the living area, and a row of houses on the north side of the square are toilets and washrooms. A brand new toilet was unloaded from the ship - not a family toilet, but a squat toilet commonly known as a "Turkish toilet" - the executive committee felt that this kind of sanitary ware that did not come into direct contact with the skin was more hygienic. The water used to flush toilets is pumped directly from the river and stored in a simple water tower behind the toilets. Bairencheng has been providing water by quality since the city was founded.
Bathrooms and toilets use the same set of drainage facilities. The sewage is discharged directly into the agricultural area downwind of the residential area through the sewage channel under the gravity of the height difference. Wu Nanhai built a large biogas tank to collect all the sewage in the city. It's all processed here.
The periphery of the entire living area is made of earth and rocks to form a low wall as high as one person. This can be used for resistance when necessary. There is only one entrance to and from the living area. The door on the steps is made of strong wooden boards, and next to it is a stone cement mortar The two-story duty room built in the building is actually a bunker, where security team members are usually arranged to be on duty 24 hours a day.
The office environment of the Executive Committee has also been improved. A two-story steel frame simple house building has been built. The interior here is much more elegant, and the furniture is all taken from the Fengcheng Wheel - these Old-style furniture that used to look old now looks luxurious and stylish, making many people jealous. There is even a LAN in the office! There are rumors among the masses that some people on the executive committee play online games in the office every night.
This put a lot of pressure on the communications team that had just obtained an office in the Executive Committee building. Many people came to the team leader Li Yunxing to request that the network interface be connected to every room as soon as possible. Some people were worried that there were not so many routers. If there is only one interface in the room, everyone cannot access the Internet at the same time. It is simply recommended to fully open wireless Internet services. Anyway, most people’s laptops have this function.
This request was ruthlessly rejected by the Executive Committee, and Gianma Qianyan instructed him to set up a communication center in Bairen City as soon as possible.
The solution adopted by the communication team in the pre-travel communication plan was actually the now-obsolete PHS system. Of course, this communication system was not ideal in practice, and it was often a "fuck, f*ck," kind of thing. However, as a time-travel communication device, it has the characteristics of simple structure and low energy consumption. As for the problem of poor signal, there was no radio interference in the air in the 17th century, and there were no buildings and high-voltage lines.
Li Yunxing brought a set of abandoned PHS base stations and controllers from local telecommunications, as well as 2 laptops, obsolete telecommunications servers, various communication wires, interface equipment, communication protocols, communication management software and a full set of communication management software. These things are enough for him to build a wireless communication network in this time and space.
Such a set of PHS base stations and controllers can support thousands of PHS mobile phones within a radius of up to tens of kilometers. If a few remote modules are added, it can also support longer distances, and internal communications within the base will be sufficient for a considerable period of time. used.
There are also more than a thousand PHS mobile phones, all of which are bought in batches with the same signal and the same batch, so that parts can be replaced and repaired when the time comes.
He estimated that the existing base station's radio power is about 5o, which can cover a 15km cellular area. To meet the requirements of the executive committee, the base station coverage should reach about 35km to 4okm, and a base station power amplifier should be installed. Increase the transmit power of each channel to 2oo, which can greatly increase the fading reserve of the system. In order to balance the power, a tower-top amplifier must also be installed to increase the uplink signal by about 12db. Overall estimation, the entire base station uses 23ov5ohz AC power supply, and the required power is 7-1ok. The report is now submitted to the executive committee to ask for a power supply quota, but now the Guatuo Mechanical and Electrical Station can provide 2ook of electricity per hour, so this power should not be a problem.
The communication team applied for the help of the engineering team to build a tower in the city and installed an array antenna. This could reduce the echo noise from surrounding buildings. Of course, there were no high-rise buildings here at this time, but it was always right to raise it a little higher.
Mr. Wen proposed that various wireless resources should be integrated as soon as possible so that radio stations, mobile phones, and walkie-talkies can communicate with each other. Regarding this reasonable request, Li Yunxing thought hard for a long time, and then gathered all the team members to study it. Finally, he had to use an indigenous method to solve it: using the air public interface protocol to provide cluster scheduling for everyone's walkie-talkies - temporary A server was built using an industrial microcontroller, and the walkie-talkie signal was simulated as a mobile phone signal and connected to the switch. This solution not only required a microcontroller, but also required the installation of an antenna due to the different frequencies between PHS and walkie-talkies.
The opening of PHS gave everyone a sense of familiarity. On the day when mobile phone numbers were released, the communication team office was crowded with people, everyone wanted a so-called auspicious number.
"I want 888888!"
"I want 168168! All the way!"
"Fart, that's mine."
"Xiao Shao, do you remember? I even treated you to dinner, so leave me one with 8!"
"You guys are so vulgar, you only know how to get 8, skinny?"
"This is called wealth! Do you understand? Illiteracy!"
"You are the illiterate. Your whole family is illiterate. You are not from Cantonese. How can you learn from this person?" The two men almost had a fistfight.
"I want 6, bring me a 6!"
Someone else said something out of the blue: "I want 444444"
"Then you might as well ask for 514514" someone made a joke on him.
Shaozong was sitting behind a table with a big box on it. He shouted at the top of his voice: "Don't mess around, everyone. Come one by one. We'll pick numbers here one by one. Those who didn't pick a number, do you know? The one you touch is the one. Hey, hey, hey. , I said you are so unconscious, you read it and then throw it back?! You have no quality!"
"Hey, Xiao Shao, can you give me a better-looking one? This phone is too ugly." This was the girl talking.
"I want the flip-top type. Why are you all straight? You're so old-fashioned!" the women were chirping. Their interest was not in the numbers but in the pile of PHS phones over there - all of them were flipping through them.
"Yeah, I don't have to choose the color... If I had known I would have brought the one I didn't want at home..." These mobile phones were purchased in batches. Except for the different colors, the styles and models are exactly the same. No wonder the girls Not satisfied anymore.
Several people in the communication team tried their best to maintain order, but seeing the scene becoming increasingly chaotic, classmate Guo Yi, who had been working nearby, stood up:
"Everyone, please don't mess up," he said. He had never worked in the security field, but he was still in the industry. He had never eaten pork before and had always seen pigs running away. Seeing that this is the time to behave, you immediately stand up to help maintain order. There was a guy with a bad temper who tried to push classmate Xiao Guo, but was pinched by his joints until he burst into tears. With such a sad example, the noisy crowd immediately calmed down.
The number selection ended quickly. Except for a few lucky ones who got the so-called auspicious numbers with 8 and 6, most people got ordinary numbers. Some people who particularly believed in this and didn't get a number were cursing unwillingly. They went to those lucky people and offered to use their own materials and equipment to exchange numbers with them.
"Business opportunities exist everywhere..." Shao Zong moved the desk back to the office with satisfaction. Just like in another time and space, the communication team - the future time travel telecommunications company, has detained all the so-called auspicious numbers. Li Yunxing and Shao Zong planned to put these numbers on the market once the telecommunications industry was restructured. Oh dear, wouldn't that be a fortune?
Seeing that the person who stood up to maintain order left without taking his number, he quickly chased after him:
"Brother, what's your name? Why don't you pick up a number and get a mobile phone?" He decided to give him a number with 8 in it to express his gratitude.
"Well," Guo Yi scratched his head and said a little embarrassedly, "I have a temporary ID card and I can't get a mobile phone now."
"Oh!" Shao Zong suddenly realized and clapped his hands, "You are that Guo Yi, right?"
"Do you know me?" Xiao Guo was a little confused. No one should recognize him here.
"Well, others don't know, but I have read the internal report our team leader got back."
"Oh? What does it say?" Guo Yi is very concerned about his future. The internal report undoubtedly represents the views and policies of the top brass of this group of bold time and space adventurers towards him.
"This..." Shaozong thought for a moment in embarrassment, "It's inconvenient to say, there is a secret level..."
***, you are really good at learning this stuff, you can master it as soon as you learn it. Xiao Guo cursed secretly in his heart, but still said with great sincerity on his face: "It doesn't matter, I just asked casually."
"I'll just show off a little bit," Shao Zong felt that being too principled would be unkind. "Are you three, the executive committee's intentions are different. Just remember this."
Is there a difference? What does this mean? Guo Yi fell into deep thought for a while.
