In the modern information society, the operating system is the foundation and core software of electronic information equipment, which is closely related to the development of national information security and various fields of the national economy. Pen ~ fun ~ www.biquge.info and as a computer program that manages and controls computer hardware and software resources, the operating system is the most basic software that runs directly on the "bare metal", and any other software must be supported by the operating system to run.

The reason why Microsoft's operating system cannot be directly introduced into aerospace vehicles is mainly because the operating system is divided into two types, one of which is the desktop operating system, such as asking and dying, the intelligent mobile operating system on the mobile phone has not developed and grown in the 90s, but there are still a little signs.

However, the biggest difference between the above operating system and the operating system of aircraft and automobile engine control equipment is that the operating system of these industrial equipment is embedded, and the flexibility of use may not be very friendly, but the stability after operation is absolutely excellent.

And the environment in which the embedded operating system works is also very different from the general computer operating system, so it is very important to have a self-developed airborne embedded operating system. The embedded system is usually used as a special computer system, which is mainly used in industrial control, national defense equipment and other fields to control and monitor the operation of various information-based devices or equipment in real time.

In fact, the embedded operating system is certainly the most widely used operating system in social life, and the operating system of the personal computer seems to use a large number of books, but compared with the embedded operating system, it is necessary to say a word hehe.

Almost all devices with digital interfaces and program control, such as satellites, rockets, airplanes, trains, automobiles, communication base stations, switches, smart TVs, set-top boxes, digital cameras, etc., are embedded devices, and they are embedded airborne operating systems, which also reflects the extreme importance of embedded operating systems in information security.

Since this can be recognized, it must be that when I heard that this time I want to prepare to use a safer domestic system on the domestic avionics operating system, it is logical to provide strong support, which makes Li Yun very moved, you must know that when he proposed to develop this system, but it was under a lot of pressure, after all, this embedded operating system is not at all simpler than the operating system of the desktop PC, if there is no investment of hundreds of millions of dollars, it is almost impossible to see any results.

But what about the difficulties, at this time, it is difficult to do: "The operating system of all our domestic information equipment is in the hands of a few Western companies, and a large number of facts have also proved that there are defects and backdoors in foreign operating systems, and in recent years, we have found countless foreign operating systems every year, and until now we are not clear how many bugs have not been found, and even these system bugs may be in the hands of the enemy." ”

The backdoor of the embedded operating system is definitely not low, at least Yang Hui knew that the foreign hacker in the previous interview had used only 20 minutes to steal the personal sensitive information of a total of 11,000 experts from the Bureau of Foreign Experts in the imperial capital of the Republic, and the router operating system used by the Bureau of Foreign Experts was the VXWaws embedded system software of Wind River.

I'm embarrassed that Wind River's VXWort embedded operating system software is used on a number of third-generation aircraft in AVIC Southwest, and if it really hits the Yankees in the future, as far as the J-18 two-seat electronic warfare model is concerned, it will be targeted at the back door of the system.....

Therefore, Yang Hui knows the extreme danger that the operating system cannot be localized, so he must vigorously support the development of the domestic system, although the domestic system has not come out before it does not necessarily have how good its reliability can be, but as long as the enemy is not clear about the specific situation of the domestic operating system, it is impossible to target a wave of precision strikes in the confrontation, and if you really want to fight hard, in the end, we may not be able to say who will die.

"Chief Engineer Li, what you said is reasonable, we must now pay attention to the needs of the localization of the avionics operating system, the J-18 uses the operating system of the American Wind River Company, which is already a non-dangerous move, and now we cannot continue to leave this dangerous design on the fourth generation of heavy wars, this is indeed a key research project, we must pay attention to it. I don't think the code name of this project has been decided yet, so I think it's better to call it the "Tianmai" system. ”

The so-called Tianmai system is actually not Yang Hui's original, but the embedded operating system independently developed by the previous face republic after 2000, the word "sky" is the meaning of the sky, the sky is not only the space for birds to fly freely, but also the field for aviation people to gallop; The "pulse" is the meaning of the veins and meridians, which is the regulatory system of the human body's functions, so that the various organs of the human body are connected into an organic whole.

Then the meaning of the name of the "Tianmai" system is about to come out, and since the domestic operating system of this plane came out in advance, then the "Tianmai" system of the computer will not have this matter in the future, it must be difficult to say, but Yang Hui believes that this name must not be broken, and what should be inherited is still inherited.

What I guessed correctly is that the whole system does not have an engineering codename, and Li Yun easily thought of its meaning after hearing this name: "Tianmai is good!" This name is loud enough, and it will be able to be famous in all directions in the future, you need to know that after our system is made, it will definitely not only be for aerospace, but also used in a large number of other fields, if there is no good name that pulls the wind and is loud, we are embarrassed to go out. ”

Generally speaking, there are a large number of pirated operating systems in the personal PC computer of the Republic, so the personal PC operating system in the Republic is not able to make the huge profits it deserves, after all, even if you are investigated by Microsoft, the company that produces the computer can also say that this is the operating system downloaded and installed by the user himself, and it has nothing to do with us.

But in the embedded operating system, this kind of excuse is absolutely impossible to exist, industrial equipment, aerospace, routers, trains, cars, communication base stations and other projects, which customer will install the operating system by themselves, unless it is a panic to burn the bag with more money, what is said to be a pirated excuse installed by the user will be laughed off.

Therefore, the embedded operating system is generally directly installed and debugged by the manufacturer, and then packaged and sold with the equipment, unless this operating system is particularly necessary, it is generally purchased genuine system, and this is where the embedded operating system is really profitable, I have no pirated system for this thing, what do you love!

Therefore, once the embedded operating system is made, first rely on the purchase order of the national defense and security system to become bigger and stronger and mature, and enter the civilian market that is to make a lot of money, and the profitability of the project will definitely not be less than the operating system of the personal PC computer, and there is no need to painstakingly find a way to maintain the entire ecological industry chain, anyway, the embedded operating system is for the industrial equipment manufacturers to specify the use of those programs.
