摘　　要：针对复杂水下环境中安全监测的应用需求,采用无线磁感应通信技术作为信息传输技术;介绍了水下无线磁感应通信原理,阐述了基于FSK调制方式的水下无线磁感应通信平台设计方案,并在模拟水下环境中进行了通信试验。试验结果表明:水下无线磁感应通信平台能够实现在水下环境中的无线信息传输;采用单向天线的水下无线磁感应通信平台在接收天线位置、角度变化情况下会出现通信中断现象,而采用全向天线的水下无线磁感应通信平台在接收天线位置、角度变化过程中能正常通信,提高了通信可靠性。For application requirements of safety monitoring in complex underwater environment, wireless magnetic induction communication technology was adopted to be information transmission technology. Principle of underwater wireless magnetic induction communication was introduced. Design scheme of an underwater wireless magnetic induction communication platform based on FSK modulation was expounded and communication test was taken out by use of the platform in simulated underwater environment. The test results show that the platform can realize wireless information transmission in underwater environment. The platform using unidirectional antenna will have communication interruption under the condition of changing position or angle of receiving antenna. While the platform using omnidirectional antenna can communicate normally in process of changing position or angle of receiving antenna, which improves communication reliability.
