What he mainly wants to design is consumer-grade unmanned aircraft technology, of course, he will carry out some unconventional work when appropriate.

The four-rotor flying machine has a simple structure and is relatively cheap.

Presumably with fixed wing, the multi-axis aircraft is easy to control and can hover at any time, which has very low requirements on the flight field.

Multi-rotor drones, various types of machines, the mechanical structure is not much different, and of course it is not particularly complicated.

With the design drawings provided by Feng Hao, Ling Mingzhi and others installed and developed very quickly.

At this time, before Feng Hao were three four-rotor drones.

These unmanned aircrafts, powered motors, can provide sufficient power performance for multi-rotor flying platforms after they are equipped with propellers.

From the perspective of the hardware of the motor and the blades, it actually mainly means that the rotation speed and pitch of the blades provide upward lift.

To put it simply, whether the aircraft can move 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 as a whole, but there were still some problems in setting up the flight control module.

With the power system, it depends on the flight control technology.

For unmanned aircraft, the flight control system is the brain of action.

How the drone moves and how it moves depends on the flight control system.

The flight control system controls the rotation speed of the motor through ESC, so that the drone can be accurately controlled and stably suspended, making flying easier.

The flight control system is mainly used for flight attitude control and navigation. For flight control, the current state of the aircraft must first be known.

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 calculations into useful things.

The performance of these machines is not particularly high, Feng Hao had to re-optimize the algorithm so that the drone can perform reasonable operations.

UAVs generally use GPS, IMU's inertial measurement unit, barometer and geomagnetic compass to measure these states.

GPS obtains positioning, and in some cases it can also obtain altitude and speed.

IMU is mainly used to measure the three-axis acceleration and three-axis angular velocity of the drone, and the speed and position can also be obtained through calculation.

The barometer is used to measure altitude.

The geomagnetic compass is used to measure heading.

The sensors of this era are deeply restricted by the design level, making the data measured by these sensors produce certain errors.

Therefore, Feng Hao needs to use fifteen states, combined with algorithms, to reasonably calculate a state with high reliability, which is combined into a navigation technology.

Combined navigation technology, combined with the advantages and disadvantages of GPS, IMU, barometer and geomagnetic compass, through the electronic signal processing technology, fusion of the measurement values ​​of multiple sensors to obtain more accurate state measurement.

After obtaining accurate data, Feng Hao has to pass an algorithm to further improve the flight control technology of the unmanned aircraft.

The advanced control algorithm of the flight control system brings high control quality to the flight and control of aerial photography drones. For example, the performance under normal conditions is high control accuracy, stable flight and fast speed.

Feng Hao felt that he did his best to allow the first-generation unmanned aircraft to fly at a speed of about 20-30 kilometers per hour.

Of course, these data have to be cleared in actual flight and practice.

To increase the flight speed, it is necessary to improve the performance and power of the device.Seven Realms Novel Network www.7jie.com

In addition, the fault diagnosis and fault handling logic of the flight control system are very important.

Before takeoff or during the flight, any minor failure may cause a flight accident.

Therefore, the flight control system needs to make certain logical judgments in real time, and it needs to constantly monitor the status of the unmanned aircraft itself, such as vibration, voltage, current, temperature, speed and other flight status parameters, and use these monitoring characteristic signals to troubleshoot diagnosis.

After obtaining these data, certain logic processing and deep learning are required.

Through data mining on a large amount 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 everything from propeller shooting in the air to IMU fault diagnosis, early prediction of faults, or emergency treatment to make flying safer.

Feng Hao specifically learned the technology of unmanned aircraft and related knowledge.

Therefore, he is very familiar with the content of this module.

At present, he needs to sort out, sort out, and integrate these technologies into his own.

Feng Hao encountered many problems, most of which were solved by himself.

Occasionally there are some technical difficulties. He consulted two other software engineers and got some enlightenment.

The two software engineers deserved to be brought in at a high price.

They are Rong Xiuxian and Nong Jiade.

Rong Xiuxian is young, in his thirties, and specializes in microcontroller software design, so he is quite familiar with this aspect.

Although Nongjiade is not well-educated, he has a rather in-depth research on unmanned aircraft related technologies, especially flight control technology.

He has studied very deeply, and Feng Hao saved a lot of time by communicating with Nongjiade and discussing some of the difficult problems encountered by him.

As for the three hardware engineers, Feng Hao is not very familiar with them.

When Feng Hao was studying and designing flight control technology, Liang Chao concentrated in the office of the Pioneer Park of Gui University.

At this time, Man Chengfu, the big fat man, also worked with everyone.

"Liang Chao, how has the Hacker 361 antivirus software been developed recently? How many users are there?"

Since Feng Hao developed the software, Liang Chao took over the general responsibility. The maintenance and development of the Hacker 361 software were carried out by him and a group of employees.

Currently, Hacker 361 has ten people, including Liang Chao and Li Guoqing, eight of whom are newly recruited, four younger sisters, and four boys. They are responsible for promoting and maintaining the Hacker 361 antivirus software.

Hacker 361 has developed very fast. It has been online for less than a month and has gained more than half a million users.

It is well received among the audience.

Liang Chao raised his head, held his glasses frame, and said: "As of 6 o'clock yesterday afternoon, we have a total of 540,000 users, and the future development will be even faster."

After saying this, Liang Chao was not very happy.

Looking at Liang Chao's expression, everyone just prepared for the joyful movement, stopped, and asked Feng Hao: "What's wrong? Users are rising fast, shouldn't they be happy? We should be able to exceed one million users before the end of the year. "

Liang Chao nodded and said, "I'm not surprised that it will exceed 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 don't have any profit method yet. We are burning money all the time."

"Yes, it is burning money in exchange for an increase in the number of users."
