The structure composition of the traversing machine

Picture transmission system

Among them, the graphic transmission system can be said to be the soul of the traversing machine. In the past, the Fat Shark analog image transmission system was commonly used in the circle. Recently, DJI has also begun to exert its strength in the field of traversing machine. The new FPV digital image transmission system can be said to be very amazing. It completely changed the use of digital transmission technology and achieved the same low delay rate as analog transmission. For example, the end-to-end delay from camera-> image transmission-> glasses screen was realized within 28 milliseconds, and the remote control delay was only 7 milliseconds. Moreover, the transmission distance of the remote control in the low delay mode could reach 4 kilometers, and there were 720. Moreover, this set includes digital image transmission, camera, image transmission sky terminal, remote control and flying glasses. There is no need to adjust parameters between components, and the built-in flight control can also be plugged in and out, which is very friendly to newcomers who have just listed.

--Flight control. This is the most important thing. The flight control decides how you want to play. If you have money and can buy pictures, then use cc3d, which is very violent. If you just want to make a plane to fly smoothly, don't use cc3d, because its lifting depends entirely on your throttle. If you don't pay attention, it will shake up and down. If you want the plane to fly stably, use apm to fly, which is highly recommended, because it has a complete ground station and can be controlled on the mobile phone! Cc3d is about 60, APM is about 150, the ground station of cc3d is called openpilot, .apm the download address of. APM is called mission planner. The landlord will download the address by himself (the subject is a novice, always thinking about violent flight control when coming up, and will dissuade him). 3. Then there is the battery. 1300mah 3s battery, no problem, remember to buy one more, the battery is about 60 pieces, remember to buy a balanced charger 204. Remote control. If you want to play normally, it doesn't matter if you want to buy a better one. It's about 250 for six links and more than 500 for nine links. 5. Receiver. When the landlord buys a remote control, he will give it to me with a receiver. 6. Then there is a picture transmission! This TM is the most expensive. . . It depends on how you want to play. If you are a local tyrant, just put on fatshark's glasses, the normal 2000 one is almost the same. If you want to pass through, and want to have video but have no money, buy a high-brightness snowflake screen, about 500, plus a 700-line camera, a good 200, and an image transceiver 1007. If the landlord wants to play a pure pass-through machine, the above options are enough, and the accessories are selected separately. But if the landlord wants to get on the plane and has to be steady, he has to add it! First of all, GPS can't be less, it's about 150, and it's best to use apm for flight control. After all, pc and mobile phone ground stations are quite hanging (again,) 8. The most important thing for APM flight control is data transmission! ! Apm flight control board is an open source flight control board made by American 3DR company, and 3DR company has made a set of related open source accessories for it, and digital transmission is one of them. The function of data transmission is to transmit all the information of the aircraft back to the ground station which is wirelessly linked with its flight control, that is to say, you can know the power, flight status, GPS position, altitude and speed of the aircraft from the ground. This is also the main reason for saving money, because with it, you don't have to use pictures to transmit! The ground station is equipped with a realistic satellite map, from which the position of your plane can be displayed, and you can let the plane fly as much as you like!
