摘　　要：传统的KJJ26矿用信息传输接口安装在监控主机机箱的插件板插槽内,通过PC总线与主机连接,安装麻烦,缺乏灵活性,对监控主机的硬件设计有一定要求,不具有通用性。设计了一种基于双端口RAM(Dual Port RAM,简称DPRAM)信息传输接口,接口安装简单方便,可以通过USB接口或串口与监控主机连接,对监控主机的硬件设计没用特殊要求,适用范围广。实践表明:新型接口采用"串并串"的设计思想,提高了数据通信速率,保证了监控系统的可靠性。In mine monitoring system, the monitoring host needs to obtain the work substation＇s data timely. The traditional K J J26 information transmission interface installed in monitoring host＇ s board, exchanging information with host by the PC bus, in- stallation of trouble,lack of flexibility. This paper put forward a kind of information transmission interface based on the Dual-Port RAM （ hereinafter referred to as DPRAM）. The USB or serial Port can be used in monitor host connection. The installation is sim- ple and convenient. Experimental results shows that the Dual-Port RAM realizes data＇ s high-speed transmission and real-time con- trol, effective improve the monitoring system＇ s work efficiency and reliability.
