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 technologies and various protocol standards make the operation and exchange of information between heterogeneous networks difficult to perform. As a complicated network connection device, the gateway can support the conversion between different protocols and realize the information sharing among multiple devices. According to the structure of the embedded system, the multifunctional gateway for mining is divided into functional modules: processor module, serial communication module and Ethernet module, which can realize the protocol conversion from RS232 / RS485 / CAN to IP and through optical fiber and twisted pair Line or telephone line access to Ethernet for longer distances.
