| 摘 要： | 设计了用R1120十六位单片机、RTL8019AS以太网控制芯片和73M2901 MODEM接口芯片组成的远程数据通信板，该板既可利用普通电话线拨号上网，也可通过以太网与互联网相连；通信板利用RS232串口通过自定义协议实现与下位机的准确数据通信，下位机通过该板与互联网相连；采用R1120汇编语言(指令与80C186兼容)实现了PPP、以太网、TCP／IP、ICMP和ARP等协议。试验表明，以单片机为中心的嵌入式设备借助该通信板能有效地实现与远程服务器之间的可靠数据通信。

| Abstract: | A Data Communicating Board was designed to realize communication using R1120 ,a sixteen-bit singlechip, microcomputer Modem controller 73M2901 and a modem interface chip 73M2901,which can connect Internet both through telephone line and LAN.Using RS232 serial port ,the board can accurately exchange data with subordinated host by the protocol defined by itself.By way of this communication board, subordinated host connects Internet. Several protocols such as PPP,Ethernet,TCP/IP,ICMP and ARP are implemented by this board .Driving programs are written by R1120 assemble language. System tests are performed and results show that the scheme used in this board is effective ,which can realize reliable communication between embedded facilities and remote server. |
