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.
