What is the receiver in the traversing machine?
In the world of flying machines, the receiver (Receiver) is a crucial component. It is responsible for receiving the signal from the remote controller and transmitting it to the flight control system, thereby controlling the flying machine. This article will introduce in detail the definition, functions, types of receivers and how to choose a suitable receiver.
1. Definition and functions of receiver
The receiver is the bridge between the traversing machine and the remote controller. Its main function is to receive the radio signals sent by the remote controller, decode these signals and pass them to the flight control system. The flight control system adjusts the speed of the motor according to the received signal, thereby controlling the flight attitude and direction of the traversing aircraft.
2. Type of receiver
According to different communication protocols and connection methods, receivers can be divided into the following types:
| Type | Features | Applicable scenarios |
|---|---|---|
| PWM receiver | Each channel outputs PWM signal independently, and the wiring is complicated. | Old-fashioned remote control system with high compatibility |
| PPM receiver | All channel signals are transmitted through a single wire, making wiring simple | Early traversal machine, simplified wiring |
| SBUS receiver | Digital signal transmission, strong anti-interference ability | Modern traversing machine, high-precision control |
| IBUS receiver | Similar to SBUS, but with different protocols | FlySky remote control system |
| CRSF receiver | Low latency, high bandwidth | Racing traversal machine, professional pilot |
3. How to choose a receiver
There are several factors to consider when choosing a receiver:
1.Compatibility: The receiver must use the same protocol as the remote control (such as SBUS, IBUS, etc.).
2.Dimensions and weight: Micro traversing machines require small and lightweight receivers.
3.Anti-interference ability: When flying in a complex environment, choose a receiver with strong anti-interference ability.
4.delay: Racing or fancy flying requires a low-latency receiver.
4. Popular receiver recommendations
| Model | Agreement | Features | price range |
|---|---|---|---|
| FrSky R-XSR | SBUS/CRSF | Small, low latency | 100-150 yuan |
| TBS Crossfire Nano | CRSF | Long distance, anti-interference | 300-400 yuan |
| FlySky FS-A8S | IBUS | Lightweight and cost-effective | 50-80 yuan |
| BetaFPV ELRS Nano | ELRS | Open source protocol, high bandwidth | 120-180 yuan |
5. Installation and debugging of receiver
When installing the receiver, you need to pay attention to the following points:
1. Try to stay away from motors and ESCs to reduce electromagnetic interference.
2. The antenna should be placed perpendicular to the fuselage to avoid signal obstruction.
3. Correctly configure the receiver protocol and channel mapping in the flight control software.
6. Frequently Asked Questions
Q: What should I do if the receiver has no signal?
A: Check whether the frequency binding between the remote control and the receiver is successful, and confirm whether the protocols match.
Q: What should I do if the receiver signal is unstable?
A: Check whether the antenna is damaged, try to change the location of the receiver or use a model with stronger anti-interference ability.
Summary
The receiver is an indispensable part of the aircraft system, and choosing the right receiver can significantly improve the flight experience. Whether it's racing, fancy style or long-distance flying, there is a corresponding receiver solution. Hopefully this article will help you better understand what a receiver does and make an informed choice.
