After having a general direction, Feng Hao seriously studied the flight control technology.
He mainly wants to design consumer-grade unmanned aircraft technology, of course, will do some unconventional work.
The four-rotor flying machine has a simple structure and is relatively cheap to manufacture.
Unlike the fixed wing, the multi-rotor aircraft is easy to control and can hover at any time, and the requirements for the flight site are very low.
Multi-rotor drones, various types of machines, the mechanical structure is not much different, of course, it is not particularly complicated.
Due to the design drawings provided by Feng Hao, Ling Mingming and others installed and developed very quickly.
At this time, in front of Feng Hao were three quad-rotor unmanned aircraft.
These unmanned aircraft, powered by motors, are equipped with propellers to provide sufficient power performance for multi-rotor flight platforms.
From the perspective of the hardware of the motor and the blade itself, it actually mainly means that the rotation speed and pitch of the blade provide upward lift.
To put it simply, whether the aircraft can move or not depends on the power system such as the motor and blades in the middle.
Feng Hao looked at the whole machine and found that there was no problem on the whole, but there were still some problems in setting up the flight control module.
With the power system, you have to look at the flight control technology.
For unmanned aircraft, the flight control system is the brain of the action.
How the unmanned aircraft moves and how it moves depends on the flight control system.
The flight control system controls the rotation speed of the motor through the ESC, so that the unmanned aircraft can be accurately controlled and stably suspended, making flying easier.
The flight control system is mainly used for flight attitude control and navigation. For the flight control, the current state of the aircraft must be known first.
For example: three-dimensional position, three-dimensional velocity, three-dimensional acceleration, three-axis angle and three-axis angular velocity, etc., a total of fifteen states.
These data need to be obtained together, and through complicated operations, they can be turned into useful things.
The performance of these machines is not particularly high. Feng Hao has to re-optimize the algorithm so that the unmanned aircraft can perform calculations reasonably.
Drones typically measure these states using GPS, the inertial measurement unit of the IMU, barometers, and a geomagnetic compass.
GPS can obtain positioning, and in some cases, altitude and speed.
The IMU is mainly used to measure the three-axis acceleration and three-axis angular velocity of the UAV, and the speed and position can also be obtained by calculation.
Barometers are used to measure altitude.
A geomagnetic compass is used to measure heading.
The sensors of this era are deeply limited by the design level, so that the data measured by these sensors will have certain errors.
Therefore, Feng Hao needs to pass fifteen states and combine algorithms to reasonably calculate a state with high reliability, that is, combine it into a navigation technology.
The integrated navigation technology combines the advantages and disadvantages of GPS, IMU, barometer and geomagnetic compass, and integrates the measurement values of various sensors through the technology in the field of electronic signal processing to obtain more accurate state measurement.
After obtaining accurate data, Feng Hao has to pass algorithms to further improve the flight control technology of unmanned aircraft.
The advanced control algorithm of the flight control system brings high control quality to the flight and control of the aerial photography UAV. For example, in the normal state, the performance is high control accuracy, stable flight and fast speed.
Feng Hao felt that he did his best to make the first-generation unmanned aircraft fly at a speed of about 20-30 kilometers per hour.
Of course, these data have to be actually flown and practiced to be clear.
If you want to increase the flight speed, you need to improve the performance of the device, as well as power.
In addition, the fault diagnosis and fault processing logic of the flight control system are very important.
Before takeoff or during the flight, any minor malfunction may cause a flight accident.
Therefore, the flight control system needs to make certain logical judgments in real time, and needs to constantly monitor the state of the UAV itself, such as vibration, voltage, current, temperature, speed and other flight state parameters, and use these monitoring characteristic signals to troubleshoot diagnosis.
After obtaining these data, certain logical processing and deep learning are required.
Through data mining of a large number of fault data, a flight control fault diagnosis system is established with deep learning technology, and pattern recognition is used to determine the probability of fault occurrence.
This system can determine from the air-launched propeller to the IMU fault diagnosis, etc., to make early prediction of the fault, or to carry out emergency treatment, so as to make the flight safer.
Feng Hao studied unmanned aircraft technology and related knowledge in a targeted manner.
Therefore, he is already very familiar with the content of this module.
Currently, he needs to sort out, sort out, and integrate these technologies into his own.
Feng Hao encountered many problems, most of which he solved by himself.
Occasionally there are some technical difficulties. He consulted two other software engineers and got some enlightenment.
Two software engineers, worthy of being introduced by him at a high cost.
They are Rong Xiuxian and Nong Jiade.
Rong Xiuxian is young, in his thirties. He specializes in single-chip software design, and is relatively familiar with this aspect.
Although Nongjiade is not highly educated, he has a deep research on the related technologies of unmanned aircraft, especially the flight control technology.
He specialized in very in-depth research. Feng Hao encountered several difficult problems. Through communication and discussion with Nongjiade, he came up with a temporary solution, which saved Feng Hao a lot of time.
As for the three hardware engineers, Feng Hao was not very familiar with them, and they mainly connected with Ling Mingzhi.
…
When Feng Haozai was researching and designing flight control technology, Liang Chao and everyone gathered in the Pioneer Park office of Guida University.
At this time, Man Chengfu, the big fat man, also worked with everyone.
"Liang Chao, how is the development of Hacker 361 antivirus software recently? How many users are there?"
Since Feng Hao developed the software, Liang Chao has taken over the responsibility of the general manager. The maintenance and development of Hacker 361 software are all carried out by him and a group of employees.
At present, Hacker 361 has ten people including Liang Chao and Li Guoqing, of which eight are newly recruited, four girls and four boys, who are responsible for promoting and maintaining Hacker 361 antivirus software.
Hacker 361 is developing very fast, and within a month of its launch, it has already gained more than half a million users.
It is well received by the audience.
Liang Chao raised his head, held the frame of his glasses, and said, "As of 6 o'clock yesterday afternoon, we have a total of 540,000 users, and the development will be faster in the future."
After saying this, Liang Chao was not very happy after that.
Looking at Liang Chao's expression, everyone just prepared to be happy, stopped and asked Feng Hao: "What's wrong? Users are rising fast, shouldn't they be happy? We should be able to break through one million users before the end of the year. "
Liang Chao nodded and said, "I'm not surprised that it will break through one million users before the end of the year."
Spreading his hands, Liang Chao continued helplessly, "However, our server can no longer support millions or tens of millions of users, and the server has to be purchased again."
"This expenditure will be huge, and we, as we don't have any way to make a profit, are burning money all the time."
"Yes, it is burning money in exchange for an increase in the number of users."
Please report us if you find any errors so we can fix it asap!
