摘要
超高频(UHF)无线电通讯系统因其自由灵活、信号穿透力强、可满足多方面通讯、便于安全管理等特点,正逐步应用于海洋工程项目。但UHF频段信号衰减大,信号易受干扰或被截断,为了减少信号的衰减,需要研究合理的UHF系统设计和设备安装,同时需要计算UHF通讯信号的覆盖范围及强度。文章根据设备型号的不同,考虑了影响信号传输的各种参数,并通过计算分析得出了可行的计算结果,可供后续的海洋工程项目借鉴。
UHF communication system is used in more and more offshore projects as it is flexible, it has high penetration communication signal, it can promote more various communications and it can be safely managed. But because of the serious loss of UHF signal, the UHF system should be reasonably designed; the equipment should be reasonably installed, and the UHF communication signals' coverage and strength should be calculated. According to the different types of equipments, the practicable calculating results are obtained by considering the parameters which may have influence on the signal transmission, which can provide reference for the following offshore projects.
