分析了RTL8019AS以太网控制器与主处理器的接口、与以太网的接口以及主处理器对它的驱动程序的设计方法。在此基础上设计了以单片机驱动RTL8019AS网络控制器实现无线接收模块转以太网(10M)的网络接入方案并应用在医疗远程监护系统上,以客户端/服务器(C/S)模式实现了医生对患者的远程监护和诊断。
The interface between the RTL8019AS Ethernet controller and the host processor, the interface with the Ethernet and the design method of the host processor to the driver are analyzed. Based on this, we design a network access scheme that the RTL8019AS network controller can realize the wireless receiver module to Ethernet (10M) by using the singlechip driver RTL8019AS and implement it in the medical remote monitoring system with the client / server (C / S) mode Doctor’s remote monitoring and diagnosis of the patient.
