Design of Multi-Functional Gateway in Mine Internet of Things

Mine Internet of Things can be divided into 3 layers: sensing layer, network layer, application layer. Multi-functional gateway of Mine Internet of Things works at the edge of the network layer, and it both has access and transmission functions. It can make use of various communication media like optical fiber, cable and radio waves. It also adapts to a variety of protocol interfaces like industrial ethernet, WiFi, ZigBee、CAN, RS485, RS232 and so on. It can convert information of sensing layer into ethernet data which can be transmitted by Gigabit fiber ring network.
