Chapter 99: Big business

Song Wenhua went on to say: "Student Xiao Tan originally used an electronic level as the state-sensing sensor of this quadcopter, but the quality of this thing is heavy and accurate, and the response time is slow. Of course we can understand Xiao Tan. The classmates were short on resources at the beginning, but now—"
Song Wenhua deliberately prolonged his tone and paused. After seeing everyone's attention, he continued: "Now, we use a "single-axis piezoelectric gyroscope" to replace the original equipment, which not only greatly reduces The weight is increased, and the accuracy and sensitivity are also improved."
"Of course, other flight control systems still use Xiao Tan’s design, but with proper optimization and miniaturization. For example, a programmable z80 chip is reserved as the CPU of the entire flight control system, with four independent powers. The regulator acts as an actuator for attitude control."
Having said that, he glanced at Tan Zhenhua with a smile, and then said: "However, I want to commend him. The flight control software of student Xiao Tan is quite good, and the algorithms and control processes in it have many fantastic ideas. We hardly made any changes to the framework, but made appropriate adjustments to the control parameters according to the actual situation of the machine. Student Xiao Tan’s programming is quite good, and many of our teachers who specialize in block analysis gave a thumbs up. "
Tan Zhenhua was depressed when he heard this.
This entire quadrotor was changed by Professor Guo and Song to be completely unrecognizable. After all, the two of them are veterans who play airplanes, but the only remaining flight control algorithm is not made by him. It is based on his own. The public version copied from his memory, co-authoring this new quadcopter is nothing like Tan Zhenhua.
Besides, Professor Song, what do you mean by simply boasting about the flight control program?
However, Young Master Tan Er's cheeky is rare in the world, and no one in the world can compete with him for copyright, so he accepted this compliment with peace of mind.
"Finally, we made some improvements to the photographing part. The original 1503II, which is the electronic shutter version of the 1503 camera, is a 14-frame film feeder. We changed it to a 36-frame film, and it also has three-frame continuous shooting. Energy is supplied and the control system is integrated into the remote control handle, which greatly improves the detection capability of this machine."
Song Wenhua ended his introduction with the practical function of this quadcopter.
Zhan Nuozhu, who had been fainting for a long time, finally heard one that he could understand. He was overjoyed and said, "This is a good change. It would be better if the camera can be installed someday!"
Tan Zhenhua interjected: "This is not impossible. In the future, when the entire camera structure evolves from "optical-mechanical" to "optical-electronic", the volume and weight will be greatly reduced, and the camera and video camera will also be integrated. "
"There is this development?"
It is rare that the three great gods present in this room unexpectedly agreed.
It's no wonder that in the 1980s when entertainment was extremely scarce, photography had quite a lot of fans, especially in places like 4014 and Ning Hang where senior intellectuals got together, and all of them happened to be present.
Tan Zhenhua explained: "Yes, I seem to have seen it in any magazine. As early as 1975, Kodak in the U.S. manufactured the first digital camera with "light-electricity" sensing in the laboratory. At the beginning of the year, the Sony Corporation of Japan manufactured the first digital camera "Mavica" that can be put into practical use, with a resolution of 280,000 pixels.
Don’t look at this thing. Although the performance is not good now, but according to the current development trend of electronic technology, I personally think that within 20 years, the "mechanical-optical" cameras in the civilian market will be completely eliminated, and digital cameras and camcorders will be completely eliminated. Fully occupy the market. And in our field," he pointed to the drone in front of everyone, and continued: "Miniaturized digital camera-video camera will be its best companion. "
Song Wenhua said longingly: "If one day, this little toy can be equipped with a real-time data transmission system and a positioning system, then it will be an artifact of local battlefield reconnaissance and monitoring. I think every company will not , Each row is equipped with one, how much demand does that have?"
Oops, a person who didn't pay attention to leak his mouth, reminded the old man and asked him to see through the potential market, no, someone wanted to grab business!
Fortunately, there is another person here who is more concerned about other issues. Ben put it aside and said: "Okay, I have said everything that should be said. Let's see how to solve the problem of radar finding this kind of target. I think, This problem will be resolved sooner or later."
So the three great gods began to discuss how to solve this "low, small, slow" target detection and capture problem. For this topic, Tan Zhenhua is currently not interested. This is because the research on this problem is too advanced. Although Tan Zhenhua has a ready-made solution in his mind, the current domestic technical reserves and industrial foundation cannot be realized at all.
And more importantly, it is not time to solve this problem urgently.
He has something else to talk to Zhan Nuozhu.
So he pulled this guy's sleeve and motioned to him.
Zhan Nuozhu originally just wanted to have a drone like this one in southern Xinjiang to try and see the effect. The difference between his father and his father is now basically reached. Only after the prototype has flown through the envelope, the internal parameters will be adjusted. As long as it was his, he didn't want to listen to those who talked about technical issues like the heavenly book. Tan Zhenhua called him, and he just went out to breathe.
The two came outside the house, Tan Zhenhua hesitated, but made up his mind, and said to Zhan Nuozhu: "Brother Zhan, I have a business that benefits the country and the people, and I want to talk to you."
Zhan Nuozhu was taken aback when he heard the words, he asked, "What business do you have that doesn't talk to your little friend Zheng Xiangqing, come to me? I have a public office, and I can't mess around with you."
Tan Zhenhua said with a smile: "This business is not the same as Zheng Xiangqing's small business. It is a big business, and it must be done only if you come forward. I guarantee it absolutely. Let you break discipline."
"Oh? There is such a thing? Come and listen."
"No, you have to promise to help first, or I won't tell you about this business, otherwise, there will be nothing for me."
"What is it, so mysterious, well, I believe you this time, I promised, as long as it doesn't violate party discipline, national law, or organizational discipline, I will definitely help you."
"That's OK, don't regret it!"
"My Zhan Nuozhu always spit and nail one by one.
Hearing Zhan Nuozhu's guarantee, Tan Zhenhua grinned, and muttered in front of Zhan Nuozhu's ear. He heard that Zhan Nuozhu's face changed continuously.
