    摘要:

    海事FBB站主要承担岸船数据传输以及应急通信任务,针对某船载海事FBB站开机后天线无法启动跟踪目标卫星故障,从设备组成和工作原理等方面出发,详细说明了故障排查的步骤。通过梳理系统自检报告和系统启动流程,测试分析各模块输出信号,定位了故障芯片。对比历史数据,分析了设备工作环境、震动、遮挡等外部因素对天线工作的影响,总结出通过温湿度控制、防氧化处理,以及编写海事监控系统爬虫软件等预防性检修维护设备方法,对同类型设备故障的分析排查有着极为重要借鉴指导价值。

    Abstract:

    The maritime FBB station is mainly responsible for the data transmission and emergency communication of ships. To solve the problem that the ship-borne maritime FBB station is unable to track target maritime satellite after system booting, detailed troubleshooting steps are illuminated after introducing the components and working principle of FBB station. After analyzing the system self-checking report and booting sequence, output signals of each modules of FBB antenna are measured and analyzed, and the breakdown chip of antenna is located finally. By comparing with the historical data, effects on FBB antenna of external factors such as working environment, vibration and shelters are analyzed, and methods to prevent system failures such as temperature and humidity control, anti-oxidation treatment are introduced. Preventive maintenance methods such as developing maritime FBB station surveillance software is proposed, which is very valuable for analysis and troubleshooting on the same type of equipment.
