摘 要:水情无线数据通讯首先要解决无线电信道质量问题 ,受通信设备和规模影响 ,通讯网内干扰、抗干扰、频率分配等成为突出问题 ,这些技术问题直接影响水情通讯的效果。近年来 ,超短波通讯网络干扰异常严重。针对超短波电台网络在水文工作中应用存在的一些问题 ,分析、讨论了超短波无线电报汛中常见干扰现象的成因机理并结合实际提出了相应的防范措施。Radio of data communication of hydrographic intelligence solving first the quality of channel ,which is related to the facility and the scale of radio and the problem of interference ,anti-interference and the distribution of channel. The technology problems mentioned above impact the communication effect of hydrology intelligence and the development of it in the future especially in the time when the interferences of radio in the supershortwave networks become severity. In this article which is mainly about the problems usually occurred in the network of the radio of supershortwave when it is used in hydrographic affairs, reasons leading to the interference generated in flood report while applying the radio of supershortwave are analyzed and discussed. Resolution of corresponding precaution is also presented in this article, according to the problems mentioned above.
关 键 词:无线电报汛 阻塞干扰 互调干扰 水文工作 水情无线数据通讯
