Public-Private Integrated Multimedia Dispatch Communication System

Application Scenario: Designed to meet the demands of analog-to-digital transformation, informatization, and intelligent development in the railway communication sector. It addresses diverse communication requirements between trains and ground control under long-haul railway routes not covered by a single network.

Developed without directly referenceable international or domestic precedents, the heavy-haul railway public-private network integrated broadband dispatch communication technology resolves the most urgent and critical issues for China's heavy-haul railways in achieving multi-locomotive traction operation. These include the integration of MCX (Mission Critical Communications) with railway-specific services, universal applicability across public and private networks, and reliable real-time transmission for locomotive consist control, brake pipe pressure control, and operational parameters. The solution focused on key technological challenges such as multi-layer encryption for broadband network transmission, dynamic authentication, signaling compression, modular unit design, OTT architecture, multi-service coupling, multi-channel transceiver capabilities, and high-precision Beidou positioning. It culminated in the development of an MCX dispatch communication system platform, which comprises servers for dispatch, network management, system-wide audio/video recording, intelligent networking, dispatch order/train number transmission, and locomotive consist communication, alongside equipment such as dispatch consoles, station terminals, locomotive radios, handheld devices, and emergency terminals.
