Abstract: In recent years, GPS (Global Positioning System) and GPS have developed vigorously in various industries, especially the application of GPS in monitoring vehicles. With the sustainable development of economy, higher requirements are put forward for public transportation. According to the staff of bus companies in China, bus companies promise to equip each bus with only one driver and implement automation. For the safety of public transport system, intelligent and automatic voice system of bus stop sign is urgently needed.

The bus stop board designed by Atmel Company takes AT89C5 1 single chip microcomputer as the control core, and combines with the global positioning system (GPS) to collect and analyze the bus position in real time. When the vehicle arrives at the predetermined position, the AT89C5 1 voice function will display the name, broadcast and other information on the LCD to realize the full-automatic stop board. When the GPS signal is influenced by the outside world, it also In addition, it is more humanized to use ISD 1720 module to store massive speech materials.

This station can not only provide automatic stops on buses, but also provide some security. Moreover, it can be applied not only to buses, but also to stop signs and LCD screens of trains and buses.
