Design of Communication Interface in Multi-function Gateway for Mine
Fang Mi-mi · Coal Mine Machinery · 2012
The diversity of interface technology and variety of different protocol standards,maked operation and information exchange between heterogeneous networks difficult.The gateway as a complex network-connected device,can support conversion between different protocols,and achieve information sharing among multiple devices.The multi-function gateway for mine which this paper designed,by reference to structure of embedded system we divided design into function module: the processor module,serial communication module,Ethernet module,it can achieve conversion from RS232/RS485/CAN to IP protocol,and obtain more long-distance transmission through optical fiber,twisted-pair or phone line access Ethernet.
