Railway Train Wireless Video Transmission System for Real-Time Monitoring Inspection Vehicle Uses

소개

With the development of intelligent railway inspection technology, unmanned railway inspection vehicles are becoming an important tool for improving railway maintenance efficiency and safety.

A railway inspection vehicle needs to collect real-time video information from onboard cameras and transmit the video back to the control operator. For long-distance inspection applications, 믿을만한 train railway wireless video transmission system is required to provide stable video communication between the moving vehicle and the monitoring station.

This application focuses on a railway diagnostic vehicle prototype that requires wireless video transmission over a distance of approximately 15 km.

Application Requirement

The customer is developing a non-human railway vehicle designed for railway track diagnostics. The vehicle is equipped with cameras to capture real-time images of railway tracks and surrounding environments.

We are making a prototype of non-human vehicle for railway, which will be used for railway road diagnostics. We need to send video from vehicle camera to operator for 15 km 거리.
Can you offer me any product?

The main requirements include:

• Real-time video transmission from the railway vehicle to the operator station
• Long-range wireless communication up to 15 km
• Stable video link during vehicle movement
• Low latency for monitoring and operation
• Reliable performance in outdoor railway environments

The transmitted video can help operators monitor railway conditions, identify potential problems, and support railway maintenance operations.

Key Technical Considerations for 15 km Video Transmission

에이 15 km wireless video link requires careful evaluation of the communication environment.

가시선 (로스) 정황

If the transmitter and receiver antennas have a clear line of sight, long-distance wireless video transmission becomes more achievable.

Important factors include:

• Antenna gain
• Transmitter power
• 수신기 감도
• 주파수 선택
• Installation height

---

비가시선 (NLOS) 정황

For railway environments with obstacles such as:

• Mountains
• 건물
• Trees
• 터널
• Infrastructure equipment

the wireless link becomes more challenging.

For NLOS applications, the antenna installation height difference between the vehicle and the operator station should be evaluated.

The customer should provide:

• A simple system layout drawing
• Transmitter antenna location
• Receiver antenna location
• Distance between two points
• Height difference
• Possible obstacles

This information helps engineers select the appropriate wireless video transmission equipment.

Video Interface and Performance Requirements

Before selecting the wireless transmission system, several technical parameters need to be confirmed:

카메라 인터페이스

Possible video sources include:

• HDMI 카메라
• SDI camera
• Ethernet/IP camera
• MIPI camera

비디오 해상도

Depending on inspection requirements:

• 720피
• 1080피
• 4케이

can be considered.

전송 지연

For real-time railway monitoring, low latency video transmission is important, especially when operators need to control or respond to the vehicle movement.
