摘　　要：在船用测控系统中,需要将船只的各种信息数据叠加到指定的视频信号中,然后经由双绞线传输并显示到测控中心的监视器上。结合船用测控系统的需求,采用模块化的设计方法,开发了多路视频字符叠加和双绞线传输系统。船用环境下的应用结果表明:本系统工作稳定可靠,完全满足设计要求。Some informations closely related to the ship are added to the video signals, then are transmitted to the monitors of marine measurement and con-trol system. According to the specified system demands, the marine multichannel OSD and twisted-pair transmission system are developed based on modular design. It is proved by experiments in different marine operating environments that the system can work well and completely meet design requirements.
