At this stage, the company's most important scientific research task is the research and development of Tang Dynasty Automobile and the laying of network communication system. Although the central government has approved private enterprises to enter the network communication service industry, it has not yet been announced, so Shen Danqing still does not know that a big pie has been smashed on his head. However, the pace of laying the fiber optic cable network has not stopped, and the first is the internal LAN in Huizhou City and Changsha Industrial Park. This is followed by the backbone fiber optic cable from Changsha to Huizhou, which is the backbone fiber optic cable connecting South China and Central China. At present, double-wire laying is used, and now of course there is no need for so many optical fibers, not even a single optical cable. However, it is mainly considered that laying optical cables is very time-consuming and labor-intensive, and because the optical cables are self-produced, the cost is not high, so in order to expand the capacity in the future, double wires are laid.

One fiber achieves 120 km of signal attenuation, and the performance indicators are sufficient. Because the straight-line distance between a county and a county is generally only a few tens of kilometers, a 120-kilometer-long fiber optic cable is not actually used. Even in another hundred years, the performance of this kind of optical cable produced by the Institute of Electronics will be enough.

It is best to lay fiber optic cables during the idle time of the farmland after the autumn harvest. Although it is paved along the road, it is usually paved in the farmland next to the road in order to reserve the future expansion of the road. Dig about 1.5 meters deep, without affecting the use of farmland above.

The backbone optical cable of Changsheng Investment Group is a little different from our current backbone optical cable, there is no splitter between counties, and it is directly a whole line. So don't think about any waterproof problems, the casing outside the optical cable can be hastily covered, not used for waterproof treatment, you can save a lot of trouble.

Of course, there is also an operation well every 50 meters to 100 meters, which is used to increase the fiber optic cable in the future, and there is no repeater or splitter or anything in it, so it is also very simple, similar to the sewer well.

The use of small excavators to dig hooks, multi-stage synchronous construction, so the progress is still very fast, I don't know how many times faster than road construction.

When you get to the county, there are sewers that can be borrowed, and the speed is faster. The computer room in the county is the network exchange room, which is not needed for the time being, so the computer room only needs to do end face tapping and reserve pigtails. In the early days, the fiber optic network would not reach the county at all, and a network switch would not be added unless the local government required it. That can be increased at a later stage without affecting the laying progress of the backbone optical cable. But in larger cities, there must be network switches, such as Guangzhou, and there must be a computer room in each district.

One fiber is not just one user, but eight. This is a time division code address technology invented in the United States, when the optical signal is transmitted, it is not as coherent as the light of a flashlight, but as a signal lamp is flashing and flashing, which is called a signal package in professional language. Taking advantage of this feature, each user terminal is a code address, and they are separated into different time periods to send signal packets, so the same fiber can accommodate 8 users at the same time.

Our current network access rules can be solved by using optical splitters on the user side or in the cell, but it is different when it comes to the network switch room. Because the eight users in the same optical fiber access different URLs, the network switch must have a photoelectric converter to read the URL that the user wants to access, and then assign these eight users to different backbone fibers through the system software. This severely limits internet speeds.

However, the unique cloud technology of Changsheng Investment Group is different, the user's computer cannot directly access the website, it is only connected to the user's personal cloud, and then the website is accessed by the personal cloud. In other words, between the cloud and the user, it is one-to-one, not one-to-many, which is much simpler. Again, although there is no LAN in the community or unit, it is all a fiber directly connected to the cloud, but there is still a LAN in the cloud. Therefore, the eight users of this optical fiber are connected from the cell to the cloud, and they are also adjacent to each other in the cloud, forming a cloud LAN. From here, it can be seen that the network switch of Changsheng Investment Group is different from the switch of our current time and space. It does not require a photoelectric conversion module and system software, it is a larger optical splitter, which is a purely physical connection. Therefore, there is no problem affecting the network speed, and the judgment is made. In terms of network speed alone, the network technology of our current time and space is far weaker than the network technology of Changsheng Investment Group, which is the advantage of backwards.

Yes, you heard it right, it is backward, and in the past nine years, it has become a backward in 2017. This is the advantage of the reborn, he knows that there is cloud technology in the future, and after careful consideration, he has formed a unique network layout of Changsheng Investment Group. Some of the LAN and metropolitan area networks that affect the speed of the network have been omitted. Gather them all in the cloud. Below the cloud, all are purely physical layer connections, and a single fiber is directly connected from the user to the cloud. Not only does it save trouble technically, but it also greatly improves the network speed.

From the above, the speed of trunk cable laying is still very fast. The optical cable is laid from Changsha to Huizhou to the cloud, and the cloud is the supercomputer room, which is placed in the Institute of Electronics, at one end of Changsha, and is also in the Institute of Electronics.

In the cloud, it is more complicated, and the first is the need for ultra-high-performance supercomputers. Because it replaces all the web servers, all the shared URLs and personal URLs, all of them are gathered on it.

Second, it requires ultra-complex system software technology, which is the foundation of intelligent cloud technology. Fortunately, the network content of more than 90 years is still relatively simple, far less than the 21st century network content, and far from so many users. But there is one more intelligent cloud technology than 21, that is, intelligent Internet of Things technology. This was ordered by Shen Danqing to be studied, and they had already started researching, which was the early networking technology, which was actually the prototype of the Internet of Things.

Since it is called intelligence, of course, there must be intelligent voice technology. Intelligent voice is a thing that is really complicated to say that it is complicated, but in some specific places it is simpler.

First of all, intelligent voice is to solve the problem of manual operation, you only need to speak, the computer will help you do it, no longer need you to use the keyboard to operate. For example, smart lighting, you and your wife want to have a romantic candlelight dinner, of course, not with candles but to dim the lights, forming a hazy artistic conception, full of poetry. Then you just need to say X.X. dim the light, and the smart computer will dim the light without you having to do it manually. The XX here is the name of your home smart computer, you say this name, it is equivalent to a boot signal, and then it will operate according to your command.

This is the specific environment, there are no too complicated instructions to operate the lights, nothing more than turning on the lights, dimming and brightening or something, a few simple instructions, so the computer is also easy to understand and do your voice commands. There is a key word in this, and that is light, so the computer does not need to associate other command tasks.

For example, if you are in an elevator and you suddenly want to go to another floor, then you just need to say X.X will send me to such and such a floor. Then the brain will be able to easily understand what you mean and do it. Because there are only so many elevator instructions, it is easy to design several voice command templates, and it is easy to compare them one by one. X.X. here generally refers to the networked brain.

These two examples illustrate that intelligent voice is indeed complex when integrated together, but it is not complex in a specific environment, and software engineers can easily do it.

There is also a key problem with intelligent voice, that is, the pronunciation is very stiff, everyone knows that it is very stiff and dull after using iFLYTEK voice software. But Changsheng Investment Group solved this problem, or Shen Danqing's unique creativity solved this problem.

It's very simple to say, first of all, it is not to understand and read word by word, it is to scan the whole sentence first, understand it according to the punctuation marks at the end of the sentence and the modal words in the sentence, and then read it word by word. This needs to go through a lot of experimentation before it gradually matures. Why do we speak emotionally, that is, the mood words play a key role, and add punctuation marks at the end of the sentence, if the design is scientific, then the intelligent voice software can also read the same tone as people. Because intelligent software is actually a software engineer who sets the rules in advance.

Intelligent voice is far from being so simple, for example, if your Mandarin is not standard, then the existing technology of Changsheng Investment Group cannot solve it. At this stage, only Mandarin and Cantonese are supported, and most of China's local language families are too complicated, which is basically an unsolvable problem. In view of this, Shen Danqing instructed the soft news company to only support Cantonese and Mandarin, your Mandarin is not standard, then I'm sorry, you only have to learn Mandarin, otherwise you won't be able to experience the convenience of intelligent networks.

One of the biggest benefits of intelligent cloud technology is that it simplifies and eliminates the need for optical fiber and optical conversion modules. For example, in one company, our current LAN needs to connect complex fiber optic lines and optical converters, optical splitters, hubs, and so on. Not only is it complicated and expensive, but it also seriously affects the speed of the Internet.

First of all, the hardware motherboard of the personal cloud is significantly different from the computer motherboard, it lacks many functions, and it is only responsible for storing data, calling, uploading, downloading, networking, and so on. It doesn't have multimedia capabilities, and it doesn't need to understand the meaning of the data packet, it is only responsible for passing the data and downloading it. These packets are actually read and solved by the user's computer.

Then the user's personal cloud hardware motherboard, to another user's personal cloud motherboard, the information transmission is not with optical fiber, but with a single crystal copper wire, which transmits electrical signals and omits the photoelectric converter. The network speed is improved, because it is very close, that is, in a cabinet, so it does not use much monocrystalline copper wire.

Of course, this refers to the interior of the cloud LAN, and a company is about the size of a switch cabinet. The LAN and the external network still use optical fiber, but the distance is not far, that is, in a computer room or on the same floor, so not much optical fiber is used.
