Audio/Video Command & Dispatch System for Railway Construction Sites

Requirements Analysis of Audio/Video Command & Dispatch System for Railway Construction Sites
Addressing the voice, video, and broadband access service requirements along a mountainous railway construction site, along with the corresponding audio/video Command & Dispatch system, this solution delivers a complete end-to-end audio/video Command & Dispatch system covering access, transmission, switching, and terminals along the entire route. It integrates fiber optic transmission, wireless microwave, and 802.11n wired/wireless communication methods to build an efficient and reliable audio/video Command & Dispatch system under the complex geographical conditions of a high-speed railway construction site.

Solution Features of the Audio/Video Command & Dispatch System for Railway Construction Sites

1. A high-bandwidth dedicated communication network as the backbone, enabling two-way audio/video Command & Dispatch across the entire line;
2. Fingerprint/face attendance system for real-name management at the construction site, enabling real-time verification of staffing at each post;
3. Real-time image storage and transmission for the construction site;
4. Integrated management of the wireless trunking intercom system at the construction site;
5. Management of large fixed assets and vehicle management systems, with GPS positioning and image inspection;
6. Emergency command contingency plan management;
7. Mobile dispatch center command vehicle;
8. Public address and sound reinforcement system;
9. Voice/video recording and playback system, and fax transmission/reception system;
10. On-site dispatcher information system, WIFI trunking smart terminals, information boards, and large-screen display;
11. Construction progress management, inquiry, and monitoring system, with GIS and 3D display capabilities.
    The construction of the dedicated communication network adopts a combination of laying fiber optic cables/leasing fiber optic cables and wireless microwave methods to address information transmission at the high-speed railway construction site. Due to the complex geographical location of this project, the site conditions are not suitable for laying fiber optic cables along the entire route. Leasing fiber optic cables for the entire route requires price negotiation with operators, and the leasing costs are relatively high. Therefore, the optimal construction approach is to lease operator fiber at key points, lay self-owned fiber where conditions permit, and use line-of-sight wireless microwave relay transmission to build the transmission network for the entire link.
