A Mine Emergency Converged Dispatch Communication System Construction Plan
Aiming at the current situation where systems such as underground production dispatch telephones (350 units)…
I. Project Background
A Mine currently has several relatively independent systems, including an underground emergency broadcast system, a production wired telephone dispatch system, and a 5G wireless communication system. These systems operate independently, failing to achieve communication convergence and unified dispatch management for underground production dispatch telephones (350 units), emergency broadcast telephones (over 100 units), and 5G wireless mobile terminals (over 700 units), which does not align with the development direction of smart coal mines.
The current status of A Mine's existing systems is as follows:
- The production dispatch telephone is based on a program-controlled dispatch system. The dispatch console occupies considerable space on the workstation, making it inconvenient for duty personnel to operate.
- The information integration and binding between the production dispatch telephone and the video surveillance system are insufficient, and information display is not intuitive.
- The existing industrial video surveillance, production dispatch telephone system, 5G wireless communication, emergency broadcast, and administrative telephone systems in the coal mine operate independently, each forming its own system. The dispatch positions in the command and dispatch center operate independently from each other, and there is no effective convergence in communication methods, making it impossible to uniformly operate underground production dispatch telephones, 5G wireless communication, and broadcast intercom services from the dispatch console.
To support the intelligent construction of the coal mine, A Mine utilizes the emergency converged dispatch communication system to achieve interconnection between various communication systems in the coal mine, realize unified dispatch of these systems, enable rapid linkage and disposal under abnormal monitoring conditions, achieve efficient surface-underground coordination in emergency scenarios, accelerate emergency response speed, and gradually achieve the goals of smart coal mine construction.
II. Construction Objectives
To support the intelligent transformation of the coal mine, this project aims to establish a fully converged, responsive, collaborative, and efficiently dispatched emergency converged dispatch communication system, creating a system for efficient daily communication, rapid abnormal disposal, and coordinated emergency rescue operations.
Specific construction objectives: One-network convergence, efficient daily communication — Through the emergency converged dispatch communication system, fully converge the coal mine's production dispatch telephone system, emergency broadcast telephones, 5G wireless mobile terminals, and coal mine alarm system, enabling multi-party voice, video, and short message communication between underground and surface areas, facilitating production plan adjustments, remote consultation and repair, and daily dispatch instruction issuance for underground personnel, achieving seamless communication anytime, anywhere.
III. Construction Content
- By building an emergency converged dispatch communication system, achieve 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 services such as voice, video, SMS, and consultation among terminals connected to each communication system, ensuring full visual command and traceability during emergency incident handling, achieving the unified command and dispatch combat effect of "audible, visible, commandable, and traceable."
- Integrate the command and dispatch center system, consolidating the relatively independent desktop dispatch of the original production wired telephone dispatch system, emergency broadcast system, and 5G wireless communication system into one, achieving unified dispatch through the converged communication console.
