摘　　要：高频系统是医用重离子加速器的动力核心。发射机作为高频系统的关键部件,其稳定可靠运行,监控系统至关重要。为实现发射机工作状态远程监控数据的可靠传输,设计了基于现场可编程门阵列(FPGA)与网络接口芯片(W5100)的数据传输系统。该系统包括三部分:首先,基于FPGA与W5100设计了数据传输系统硬件;其次采用硬件描述语言,实现了TCP服务器模式(TCP Server)下的可靠数据传输;最后利用Flash Builder平台,设计了发射机数据传输系统上位机监控界面,实现了高频发射机的远程监控。经长时间测试,该系统运行稳定可靠,数据平均传输速率达到11.32 Mbps,能够完成高频发射机的远程监控。Radio frequency system is the power core of Heavy Ion Medical Machine. Transmitter, as a key component of the high frequency system, depends heavily on the monitoring system to ensure its stability and reliability. In order to perform a reliable transmission of remote monitoring data of transmitter working state, a data transmission system based on field programmable gate array（FPGA） and network interface chip（W5100） is proposed. The system consists of three parts. Firstly, the hardware of the data transmission system is designed based on FPGA and W5100. Secondly, the reliable data communication under TCP Server mode is achieved by using Hardware Description Language（HDL）. Finally, the upper computer monitoring interface is designed and realized by using Flash Builder platform. After a long time testing, the system runs stably and reliably, and the average data transmission rate reaches 11.32 Mbps. The system is capable of remote monitoring to the high frequency transmitters.
