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.
