Buses, as the most traditional means of public transportation, have undergone earth-shaking changes both in line popularity and automation degree. At present, except for a very few towns and villages, the way of manual ticket selling and station announcement is still adopted. Most of them have realized automatic ticket selling and station announcement and can predict the arrival of the auto show. In order to improve the efficiency of bus operation, this paper designed a set of display can be used for the button stops and site bus stops system design, the system can be divided into two parts, buttons control the stops and display part, this paper used as a demo only endowed with the function of the three keys, its function respectively on a station is approaching, the next stop and function, Press different buttons to activate different functions. During the test of the designed simulation system, the functions of different keys were tested to judge whether the system key module and display module can work normally. Through the analysis of a series of test results, it can be seen that the bus stop reporting system designed in this paper meets the design requirements.
