摘　　要：针对传统的广播发射机远程监控系统常需用PC机联入Internet而形成接入成本高、体积大等诸多弊端,介绍了一种低成本、小体积的广播发射机嵌入式远程监控系统。详细阐述了由ARM处理器S3C2410A作为主控芯片,RTL8019AS作为以太网接口芯片等实现以太网接口的硬件电路设计。软件设计中,在介绍Linux微内核的定制与裁剪的基础上,给出了Linux下RTL8019AS驱动程序实现的具体步骤,最终实现了嵌入式以太网的数据传输。该设计已经成功应用在广播发射机远程监控系统中,系统性能稳定可靠。A remote monitoring system of embedded radio transmitters is presented, whose size is smaller and cost is lower compared with the traditional one linked to Internet with PC. The circuit design of hardware to realize ethernet interface with ARM processor S3C2410A as master chip and RTL8019AS as ethernet introduction of Linux micro-kernel customization and tailoring, shown and embedded ethernet data transmission is achieved. The ters, which possesses a stable and reliable system performance. interface chip is elaborated. ＇in the software design, based on the the specific steps to realize RTL8019AS driver under Linux is design is applied to remote monitoring system of radio transmitters, which possesses a stable and reliable system performance.
