یک FPV Analog Camera CVBS Video SBUS/S.RSF Data to Optical Fiber Converter is a specialized device designed to transmit analog video signals (specifically CVBS format) and digital control data (SBUS or S.RSF protocols) over optical fiber. This setup is crucial in FPV (نمای اول شخص) سیستم ها, such as drones or remote-controlled vehicles, where long-distance, interference-free transmission is required. Below is a detailed breakdown:

1. Core Components

• ویدیوی CVBS:
  Composite Video Broadcast Signal, an analog video format combining luminance (brightness), chrominance (رنگ), and synchronization signals into a single channel. It is the standard output for analog FPV cameras.

• SBUS/S.RSF Data:

  • SBUS: A serial communication protocol (inverted UART) used in RC systems to transmit multiple control channels (به عنوان مثال, throttle, steering) over a single wire.

  • S.RSF: Spektrum’s Remote Receiver Serial Format, similar to SBUS, used for low-latency control data transmission.

• Optical Fiber Converter:
  Converts electrical signals (CVBS video + SBUS/S.RSF data) into optical signals for transmission via fiber optic cables. This ensures immunity to electromagnetic interference (EMI) and enables long-range communication (کیلومتر).

2. Conversion Process

• Signal Integration:
  The converter merges CVBS video and SBUS/S.RSF data into a unified digital stream using multiplexing. For CVBS, an analog-to-digital converter (ADC) digitizes the video; SBUS/S.RSF data may be packetized directly.

• Optical Modulation:
  A laser diode (به عنوان مثال, VCSEL) converts the digital stream into light pulses transmitted through fiber optics.

• Reception & Demultiplexing:
  در انتهای گیرنده, a photodiode converts light back to electrical signals, followed by demultiplexing to separate video and control data.

3. Key Technical Considerations

• تأخیر:
  Critical for FPV systems; optical fiber minimizes delay (<1 ms/km) but ADC/DAC stages add ~2–5 ms. Total latency must stay below 20 ms for real-time control.

• پهنای باند:
  CVBS requires ~6 MHz bandwidth; SBUS/S.RSF uses low-bandwidth serial data. Fiber optics easily supports this, but multiplexing must avoid data collision.

• Noise Immunity:
  Fiber optics eliminate ground loops and EMI, crucial in environments with motors/ESD (به عنوان مثال, هواپیماهای بدون سرنشین).

• Power Supply Isolation:
  Use isolated DC/DC converters to prevent noise coupling from power sources.

4. Design Implementation

• Circuit Architecture:

  • Video Path: CVBS → ADC (به عنوان مثال, ADV7180 for SD video) → Digital multiplexer.

  • Data Path: SBUS/S.RSF → Level shifter (به عنوان مثال, ADG3245) → Multiplexer.

  • Fiber Driver: Laser diode controller (به عنوان مثال, MAX3737) with automatic power control.

• همگام سازی:
  Time-stamping or hardware triggers align video and control data to prevent jitter.

5. برنامه های کاربردی

• Long-Range Drones: Transmit HD analog video and control data beyond 10 کیلومتر.

• بازرسی صنعتی: EMI-resistant video in high-noise environments (به عنوان مثال, power plants).

• Military/Medical Systems: Reliable transmission for critical missions.

6. Advantages vs. Traditional Wiring

7. چالش ها & راه حل ها

• CVBS Quality Degradation:
  Use high-resolution ADCs (≥10-bit) and anti-aliasing filters.

• Control Data Errors:
  Implement CRC checks in SBUS/S.RSF packets.

• Fiber Damage:
  Reinforce cables with Kevlar jackets for rugged use.

نتیجه گیری

This converter solves the core FPV challenges of range and interference by leveraging fiber optics. For deployment, prioritize:

• Low-latency ADCs (به عنوان مثال, sigma-delta type for high resolution).

• Industrial-grade fiber transceivers.

• Rigorous testing for synchronization between video/control paths. Applications span from consumer drones to mission-critical systems where signal integrity is non-negotiable.
