Introduction
Interpretation of the core content of the standard
On-board monitoring data train-to-ground communication system realizes real-time transmission of train operation status data through wireless communication technology. The standard stipulates key requirements such as system composition, environmental adaptability, and technical indicators.
System Architecture Design
| Components | Technical Requirements | Typical Configuration |
|---|---|---|
| Vehicle-mounted Device | Main Control Unit+Communication Module+Multi-standard Antenna | Support GSM-R/WLAN/BDS Combination |
| Wireless Network | Transmission Rate≥1Mbps | 4G(TD-LTE) Priority |
| Ground Equipment | Network Security Protection+Data Server | Comply with GB50174 Computer Room Standard |
Key Technical Indicators
Wireless Communication Performance Comparison
| Network Type | Standard Basis | Key Indicators |
|---|---|---|
| GSM-R | TB/T 3324-2013 | Railway Dedicated Frequency Band |
| TD-LTE | YD/T 2683-2013 | Downlink Rate ≥100Mbps |
| WLAN | IEEE 802.11ac | 5GHz Frequency Band Transmission |
Note: BDS short message communication needs to meet the transmission cycle of 78 bytes/60 seconds, and the success rate must be ≥95%
Implementation suggestions
- Vehicle-mounted antenna installation should avoid metal obstacles within 1m
- TD-LTE+GSM-R dual network redundant design is preferred
- WPA2 enterprise-level authentication is recommended for data encryption
- Ground servers must pass IP67 protection level verification
Standard Evolution Analysis
This standard incorporates 4G communication into the railway vehicle-to-ground transmission system for the first time. Compared with the earlier version:
- Added TD-LTE technical specifications
- Strengthened electromagnetic compatibility requirements (GB/T 24338.4)
- Clearly define BDS positioning data transmission indicators
