| 摘 要： | 在船舶自动识别系统船台检测中,为了解决发送测试信号的同步问题,提出了信号源的时隙同步触发系统设计方案。该方案是利用单片机设计实现,单片机接收到定时触发命令后,通过全球导航定位系统获取世界标准时间,在整分钟触发信号源进行信息发送,达到与时隙的同步.文章最后通过时隙分析仪来观察该系统发送信号的时隙使用情况,验证了时隙同步触发系统的正确性.

| Abstract: | In order to solve the problem of text signal synchronization in the Automatic Identification System（ AIS） receiver detection. This paper proposes a scheme which designs a timeslot synchronous trigger system of signal source. The solution is to use the microcontroller to realize synchronization. When MCU gets the timing trigger command,it acquires the time of Universal Time Coordinated（ UTC） through global position system（ GPS） and triggers the signal source to send signal in the minutes. At the very end of the article,it uses the slot analyzer to observe slot usage of the signal sending situation of the system,verifies the system＇s correctness of slot synchronization trigger. |
