Research of Unified Communication Platform of Coal Mine Internet of Things

The paper proposed a technology scheme of building unified communication platform of coal mine Internet of Things, which takes TCP/IP protocol as core, takes high-speed industrial Ethernet as backbone network, takes wireless local area network, wireless sensor network, field bus and RS485 bus as extensions. It mainly discussed architecture of unified communication platform of coal mine Internet of Things, key gateway devices, protocol system, network virtual access and implementation method of architecture of service-oriented communication platform.
