The system can report the originating station, one stop before the function and station. The system is composed of AT89C51, ISD4004, voice module and a display button LCD1602. Station information stored in ISD4004 voice module. Voice playback, playback button control information is displayed on LCD. The design consists of six groups of test results show that the system is stable and reliable. To meet the design requirements. The system hardware using STC89C52 as the CPU for overall control, the establishment by ISD4004 voice chip voice information database, and a free combination of voice information to form a diverse voice message, voice message broadcast using LM386 amplifier and voice prompts. The system software uses the C programming language software keilC51, the system to achieve the LCD display, ISD4004 voice broadcast, infrared control program such as interrupt service routine, the procedure to go through the serial port writes STC89C52, repeated testing,to make the system perfect.
