A Mine Emergency Integrated Dispatch Communication System Construction Plan
案例图集
1. Project Background
Mine A currently operates several relatively independent systems, including the underground emergency broadcast system, the production wired telephone dispatch system and the 5G wireless communication system. Each system runs independently and cannot achieve communication convergence and unified dispatch management across the underground production dispatch telephones (350 sets), emergency broadcast telephones (100+ units), 5G wireless mobile terminals (700+ units) and other systems and devices, which does not conform to the development direction of intelligent coal mines.
The basic status of Mine A's existing systems is as follows:
- The production dispatch telephone system is a program-controlled dispatch system. The dispatch consoles occupy a large amount of desk space at workstations, making it inconvenient for duty personnel to operate;
- The information convergence and binding between production dispatch telephones and the video surveillance system is insufficient, and information display is not intuitive;
- The existing industrial video surveillance, production dispatch telephone system, 5G wireless communication, emergency broadcast, administrative telephone and other systems work independently and form their own systems. The dispatch positions in the command and dispatch center operate independently of each other and have not been effectively converged in terms of communication methods, making it impossible to uniformly operate underground production dispatch telephones, 5G wireless communication and loudspeaker broadcast services on the dispatch console.
To support the intelligent construction of the coal mine, Mine A will leverage the Emergency Integrated Dispatch Communication System to realize interconnection and interworking between the mine's communication systems, achieve unified dispatch of all mine communication systems, realize rapid linkage disposal under abnormal monitoring, achieve efficient collaboration between surface and underground in emergency scenarios, accelerate emergency response speed, and gradually achieve the goal of intelligent coal mine construction.
2. Construction Objectives
To support the intelligent transformation of the coal mine, this project aims to establish an Emergency Integrated Dispatch Communication System featuring full convergence, sensitive response, collaborative linkage and efficient dispatch, building an emergency integrated dispatch communication system for efficient daily communication, rapid abnormal disposal and collaborative emergency rescue operations.
Specific construction objective: One-network convergence for efficient daily communication — through the Emergency Integrated Dispatch Communication System, the coal mine production dispatch telephone system, emergency broadcast telephones, 5G wireless mobile terminals, coal mine alarm system and other devices are all converged, realizing multi-party voice, video and SMS communication between underground and surface, supporting production plan adjustments, remote consultation and maintenance, and daily dispatch instruction issuance for underground personnel, achieving seamless communication anytime and anywhere.
3. Construction Content
- By building one Emergency Integrated Dispatch Communication System, realize the convergence and linkage of multiple systems including the production wired telephone dispatch system, emergency broadcast system, 5G wireless communication system and coal mine alarm system, completing voice, video, SMS, consultation and other services between terminals connected to each communication system, ensuring fully visualized command and traceability throughout the disposal of emergency events, achieving the unified command and dispatch combat effect of "audible, visible, commandable and traceable".
- Command and dispatch center system integration: integrate the originally independent desktop dispatch of the production wired telephone dispatch system, emergency broadcast system and 5G wireless communication system into one, achieving unified dispatch through the converged communication console.
