Design Of Public Traffic Automatic Arrival Broadcast System Based On Single Chip Microcomputer

With the continuous development and progress of the society,the process of urbanization is very rapid.In order to improve the quality of public transportation in the city and improve the efficiency of the use of public transportation tools,this design aims at making an automatic arrival broadcasting system for public interchange tools that can regulate the operation of various transportation tools in use.The site management function of public transport in cities,so as to increase people's satisfaction in using public transport.The hardware design of this paper is based on the STM32 Series MCU as the control core,using the common infrared radio signal receiving and transmitting module in the laboratory to realize the transmission of the wireless signal and the recognition of the data points.The display and play of various information is carried out by the CH12232 B liquid crystal display module produced by Shenzhen Sichuan Airlines Electronic Technology Co.,Ltd.The model WT588 D voice chip is used to play various voice messages,the sensor DHT11 is used to collect the temperature and humidity information,and the clock signal of the whole circuit is set by the DS1302 clock chip.Finally,the automatic recognition and broadcast of various public transportation tools when entering and leaving the station are simulated.Because of the rapid development of various means of transportation and the improvement of traffic requirements,this design uses an automatic arrival broadcast system based on the core of single chip microcomputer.It can control the orderly use of traffic tools in the simulation site experiment,and can solve the problem of the parking and use of new traffic tools.It is simple in construction,low in cost,convenient in use and clear in sound quality.It can effectively improve the use quality of public transportation and enhance the image of the city while relieving traffic pressure and protecting the environment.
