摘　　要：太湖风浪监测为中荷合作项目,引进的无线传输方式存在一些应用难点,需要进行改造。在分析无线传输方式存在的问题后,提出解决问题的两个关键点。介绍了改造后的通信方案,详细分析了使用CDMA 1x做为数据传输信道的方法,以及利用虚拟串口技术完成点对多点协议转换的具体方案。通过改造,可实现20km以上的RS-232串行端口数据传输,解决了中荷合作项目数据通信的难点。Monitoring system for wind ＆ wave of Taihu is a Sino-Dutch cooperation project. There exist some application difficulties in imported wireless transmission method, so it needs to be transformed. Through analyzing existing problems of the transmission method, two key points for solution are put forward. This article makes description on communication scheme after transformation and detailed schemes for applying virtual serial port technology in pointto-multipoint protocol conversion, and a detailed analysis about the method of using CDMA 1X as data transmission channel. Through transformation, that RS-232 serial port data transmission distance can be extended up to 20 kilometers, which can solve data communication difficulties of the project.
