摘要
接口技术的多样性和各种不同的协议标准,使得异构网络之间的操作和信息交换难以进行。网关作为一种复杂的网络连接设备,可以支持不同协议之间的转换,实现多个设备之间的信息共享。设计的矿用多功能网关,参照嵌入式系统结构划分了功能模块:处理器模块、串行通信模块、以太网模块,可以实现RS232/RS485/CAN到IP的协议转换,并通过光纤、双绞线或电话线接入以太网实现更长距离传输。
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 muhiple 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.
