Device and method for networking protocol conversion

Abstract

一种用于网络协议转换的设备:包括网络模块、指令队列模块、译码转换模块、数据译码打包模块、485应答接受模块、485模块和CPU,各模块分别通过系统总线连接,DP83848网络模块外接以太网、485模块SP3485外接485电表。采用上述设备实现以太电表集抄协议到标准485协议转换的方法:1、通过以太接口经以太网与运行虚拟化集中器的主机进行联接;2、接收并处理从虚拟集中器下发过来的以太抄表报文;3、将DL645规约的报文通过485总线发送出去;4、按照以太抄表协议发送回去。本发明可完成以太协议到485协议的转换,通过该设备可以在近距离高速联接一个或数个485电表,完成电表数据采集。
A device for networking protocol conversion comprises a network module, an instruction queue module, a decoding conversion module, a data decoding packaging module, a 485 replying and receiving module, a 485 module and a central processing unit (CPU). All the mentioned modules are connected through system buses. A DP 83848 network module is externally connected with the Ethernet and the 485 module, and the SP3485 is externally connected with a 485 electricity meter. The method of achieving the conversion from an Ethernet integrated electricity meter reading protocol to a standard 485 protocol by adopting the mentioned devices comprises below steps: connecting with the host computer running a virtualization concentrator through the Ethernet through the Ethernet interface, receiving and processing the Ethernet meter reading messages sent by the virtualization concentrator, sending out the messages stipulated by a DL645 through the 485 bus and sending back the messages according to the Ethernet integrated electricity meter reading protocol. The device and method for networking protocol conversion can achieve the conversion from the Ethernet protocol to the 485 protocol, through the device, one or a plurality of 485 electricity meters at a short range can be connectedly fast, and electricity meter data collection can be completed.
