What is the reception of model aircraft remote control?
In the world of model aircraft enthusiasts, the remote control receiver is the key device that connects the remote controller and the aircraft. It is responsible for receiving the signals sent by the remote controller and converting them into instructions that the aircraft can execute. This article will introduce in detail the working principles and types of model aircraft remote control receivers and how to choose a suitable receiver.
1. Working principle of model aircraft remote control receiver
The working principle of the model aircraft remote control receiver can be briefly summarized as the following steps:
1.signal reception: The receiver receives the radio signal sent by the remote control through the antenna.
2.Signal decoding: The receiver decodes the received signal and extracts the control instructions.
3.command output: The decoded instructions are transmitted to the aircraft's actuator (such as servos, ESCs, etc.) through the output channel of the receiver.
The following are the technical parameters of some common model aircraft remote control receivers:
| parameters | Description |
|---|---|
| Working frequency | 2.4GHz (mainstream), 433MHz (long distance) |
| Number of channels | 4 channels, 6 channels, 8 channels, etc. |
| Signal modulation method | PPM, PWM, SBUS, IBUS, etc. |
| Receive sensitivity | -100dBm to -110dBm |
| Working voltage | 3.3V-12V (common) |
2. Types of model aircraft remote control receivers
According to different application scenarios and technical characteristics, model aircraft remote control receivers can be divided into the following categories:
| Type | Features | Applicable scenarios |
|---|---|---|
| Ordinary receiver | Low price and simple functions | Entry level model aircraft |
| tuner receiver | Supports multiple protocols and has strong compatibility | Multi-protocol remote control |
| long range receiver | 433MHz or 900MHz frequency band, long transmission distance | FPV, drone |
| mini receiver | Small size and light weight | micro drone |
3. How to choose a suitable model aircraft remote control receiver
When choosing a model aircraft remote control receiver, you need to consider the following factors:
1.Compatibility: The receiver must be compatible with the protocol of the remote control. Common protocols include FrSky, Futaba, Spektrum, etc.
2.Number of channels:Select the number of channels according to the needs of the aircraft. For example, a quadcopter usually requires at least 4 channels (throttle, pitch, roll, yaw).
3.Transmission distance: If the aircraft needs to fly over a long distance, a long-distance receiver should be selected.
4.Volume and weight: For small aircraft, micro receivers are a better choice.
The following are recommendations for some popular model aircraft remote control receivers:
| Brand | Model | Number of channels | Agreement | Price (RMB) |
|---|---|---|---|---|
| FrSky | X8R | 8 | ACCST | 300-400 |
| FlySky | FS-iA6 | 6 | AFHDS | 150-200 |
| TBS | Crossfire Nano | 12 | Crossfire | 500-600 |
| Spektrum | AR620 | 6 | DSM2/DSMX | 400-500 |
4. Future development trends of model aircraft remote control receivers
With the advancement of technology, model aircraft remote control receivers are also constantly developing. The following are several possible development trends in the future:
1.digital agreement: Digital protocols such as SBUS and IBUS will gradually replace traditional PPM and PWM to improve transmission efficiency and reliability.
2.Integrated design: The receiver will be integrated with flight control, image transmission and other equipment to reduce wiring complexity.
3.Smart functions: The receiver may add intelligent functions such as automatic parameter adjustment and signal strength prompts.
In short, the aircraft model remote control receiver is an indispensable part of the aircraft model flight. Choosing the right receiver can significantly improve your flight experience and safety.
