High-speed railway tunnel radio intercom
In recent years, with the large-scale construction of national high-speed railways, the number of long and large tunnels has increased dramatically, and super-long tunnels are common. How to solve the emergency communication guarantee in the event of a disaster emergency inside the tunnel and ensure the comprehensive command of the railway command centers at all levels on the disaster site has become an issue that needs attention. The special emergency voice system solution for high-speed railway tunnels is formulated in accordance with the "Railway Emergency Plan for Dealing with Sudden Events in Long and Large Tunnels" issued by the General Office of the Ministry of Railways. It is suitable for emergency communication solutions for long and large tunnels over 5KM, especially over 10KM, to help users provide the last voice communication guarantee when an emergency occurs in the tunnel.

The touch screen dispatch desk supports one-to-one calls and multi-party conference functions, supports multimedia communication with the upstream dispatch desk and videophone, and supports monitoring images and pan-tilt control of network cameras, improving the dispatcher's ability to obtain communication information. | The remote control platform has an incoming call queuing function. When multiple tunnels call the central control console at the same time, the system will automatically queue the calls according to the incoming call time and wait for the operator to answer them one by one. | ||
| Multi-party call |
| Dual-machine hot standby |
| System supports multiple tunnel wired telephone extensions in the same tunnel or multiple tunnel wired telephone extensions in multiple tunnels to talk to the remote control center at the same time. There is no limit on the number of parties in a multi-party call. | Can achieve high availability architecture and automatic failover. |
