Design of multi-service linkage communication platform for coal mine

In view of requirements in Technology schemes of upgrading of coal mine safety monitoring and control system, a design scheme of multi-service linkage communication platform for coal mine was proposed. Architecture, working principle and key technologies of the platform were discussed. Based on signaling switching technology, the platform effectively integrates existing wireless communication system, wired communication system, IP emergency broadcast system, local broadcast system to realize interconnection and centralized dispatching command of various heterogeneous communication systems, and to realize unified dispatching and one-key calling of each system in emergency. Practical application results show that the platform realizes integrated control target of production dispatching, real-time command and emergency rescue, and provides an effective means for coal mine emergency rescue and communication.
