In fact, if you want to parade, you will definitely test the main equipment of the three armies. Even if it is the navy, you will drag your missiles out to show it. The army's main combat weapon is a tank. The latest 99 tank will definitely appear.
,They are not under great pressure, but Qin Zhenhua does not want his main equipment to be repeatedly reviewed and discussed by the superior department, and finally decided to participate in the military parade. This will make him feel embarrassed. His equipment is only recommended.
When you go out, you should immediately make your superiors lit up. You should use this to take the lead when making a decision. Moreover, when promoting, you should also promote the best things!
Qin Zhenhua is competitive, so now I am asking everyone to realize the informatization of tanks and make their tanks recognized by their superiors!
With this determination, Qin Zhenhua held this meeting. Now, the theme of the meeting has come out, that is, to realize the information system of the tank. However, how to implement this system?
"Now, please see a schematic diagram." Qin Zhenhua motioned Nie Qianqian to release a slide. The slide was printed with a comprehensive electronic diagram of the Leclerc tank.
The French are the most open in this regard. They can use many things in the design stage to fool people openly. Only in this way can they create momentum for their weapons. After all, their weapons and equipment are the most sold.
In the past, I chose the gap in the arms market of the United States and the Soviet Union and won many orders. Now, the Soviet Union is gone, Damao and Ermao have opened up selling arms, and the United States is also expanding their arms exports, so the French
It is becoming increasingly difficult to export arms. If you want to choose American goods in advance and choose big-grain goods cheaply, what are the characteristics of French goods? The advanced level is not enough, but the price is quite amazing!
Take fighters for example. The American F-16 has first-class performance and is cheap. One aircraft is only 40 to 50 million US dollars. The French Phantom 2000 has no better performance than the F-16, and the price is 7 to 80%
It's tens of millions of dollars, and there are also various fees such as upgrades in the future. Therefore, the price is very high. If the French want to buy their things, they must be promoted in place.
During the publicity, all kinds of information came out. Now this diagram is the publicity information from Leclerc tanks.
There is a horizontal box in the middle, just like a highway, this is the data bus, all kinds of data are transmitted through the bus, and there is a line vertically, which divides the diagram into two parts, and the things on the left are all
In the turret, the things on the right are on the body of the car, and then, up, down, left and right, there are a large number of block diagrams.
What are fire control computers, servo computers, weather sensors, sights, etc., which are dazzling.
"Everyone seems to be quite messy, but overall, these things can be divided into four parts." Qin Zhenhua began to explain in person: "First of all, the data control and distribution and subsystem. This is the data bus, responsible for in-vehicle information scheduling.
And transmission, followed by the occupant control and display subsystem. This is the human-computer interface part of the system, and there is also the computer resource subsystem. It provides intelligent resources, data and signal processing and control functions for the vehicle's functional subsystem.
Finally, there is the power management and distribution subsystem. This subsystem is responsible for allocating electricity to all subsystems on the vehicle and controlling them on and off.
Qin Zhenhua's explanation is much simpler. Seeing these things, everyone has slowly shifted from freshness to reality.
"Now, let's talk about our vision, the 1553B data bus technology has been started in China, and there are a lot of mature technologies to rely on, so we have also decided to adopt this bus technology, but for the future electronic confrontation
We have taken the lead and decided to adopt the latest solution, which is fiber optic transmission."
Although the 1553B data bus technology was invented by Americans, it is just a data bus technology standard, a series of encoding methods are formulated, etc., and the specific use is decided by the user. Take the domestic example, various
Hardware and software are all made by yourself, so don’t worry about using this standard, which may lead to leaks. After all, this standard is the most scientific, and there is no need to start a new business. As long as you use your own software and hardware, there will be no
question.
However, technology is constantly developing with the advancement of technology, the bandwidth of this bus technology will face insufficient problems and need to be improved and improved. What Qin Zhenhua said now is a kind of effective bandwidth improvement that Qin Zhenhua said
Way.
The 1553B data bus uses twisted pair transmission. Yes, it is the twisted pair commonly used in the civilian Internet. The transmission bandwidth is limited to about 100 megabytes. If the data is faster, the data transmission will be congested, and high-speed
After optical fiber, the optical signal can be transmitted inside and can easily reach the level of G, dozens or even hundreds of times faster than twisted pair cables.
Moreover, one more important reason is safety. Twisted pair transmits electrical signals and is easily disturbed, while optical fiber transmits optical signals. During the transmission process, there will be no interference. In the future, there will be
Complex electromagnetic interference is obviously more suitable for using optical fibers.
"Cough, cough." Nie Qianqian coughed for a moment, and then said to Qin Zhenhua: "Director Qin, after using optical fiber, it is called 1733 bus technology. Our own domestic standard is called G**289-87."
Obviously, Qin Zhenhua also launched the shelves. Although he has learned a lot of this knowledge in the past few days, he still lacks it. The country has used the 1553B data standard, but it does not have this name, but it is called his own.
Military standard G**289-87 was formulated based on the 1553B data bus. In the United States, in order to adapt to the development of using optical fiber as a bus transmission medium, L-STD-1773 and
The L-STD-1773A both have fiber optic transmission, the latter is faster.
Qin Zhenhua said these things, but they were not very accurate. So, Nie Qianqian was on the side and finally couldn't help but ask. After all, such a meeting was to be filed. If it was not professional, it might be
It's criticized by people.
Hearing Nie Qianqian's words, Qin Zhenhua nodded: "That's right, the number has changed. Everyone should know that technology is progressive and constantly developing. We must keep learning, live and learn until we are old."
