Regarding the technical barriers of drones, the civilian use is mainly two parts of battery life and remote control. These two technical bottlenecks do not exist in military drones, because the current top military drones use aviation fuel as the endurance power. And remote control is remotely controlled by satellite. In terms of civilian use, the battery is currently the biggest technical obstacle. The general civil drone can fly for 20 minutes, and the remote control is limited to less than 5 kilometers. If the remote line of sight is remote, it needs some special legal. The exemption. In the case of civilian drones, the use of drones for aerial photography or the replacement of rocker arms in film shooting is now the most widely used. (In addition, there are plant protection drones and security drones, etc.) and Dajiang mainly does aerial photography around drones. When it comes to Dajiang, some of my friends have no less than fruit powder in Dajiang powder. I am one of them. Here I will elaborate on several core technologies in Dajiang. First of all, the reason why Dajiang is Dajiang, a large part of its significance is its flight control technology. Let's take a look, the so-called flight control is like this. The above picture is a UAV flight control circuit board (earlier open source circuit board) before the Dajiang era. The work of the flight control circuit board is mainly two aspects. Here I am talking about multi-axis without The situation of man-machine. 1. Inductive drone level. 2. Adjust the speed of each propeller to allow the drone to reach level. In terms of flight control, DJI has achieved integration compared with other UAV manufacturers. As shown in the figure, it is the flight control of NAZA series flight control and Dajiang A series. Similar to Apple's idea, Dajiang will have an ugly circuit board that is highly integrated, and integrates high-precision gyroscopes with GPS modules, so that there are other drone manufacturers' drones. They also used the flight control of DJI, and this modular strategic thinking had to be admired. And this small flight control inherits a lot of cutting-edge technology.
