The system realizes the function of reporting the originating station、 the previous station and the next station. The system is made up of AT89C5 voice module ISD400 buttons and monitor LCD1602. Information of stations reported is stored in ISD4004 voice module. Voice player is controlled by buttons, broadcasted information is displayed on LCD. The design is tested by six groups of people and the result shows that the system works stably and reliably. It reaches the design requirements.
