Abstract Currently in use bus automatic station apparatus varied, but has its own drawbacksand limitations. Some areas are still using even simple semi-automatic-stop device, worseyet-stop device. We designed the core campus bus automatic station apparatusmicrocontroller campus bus stations means there are both manual and automatic, the maindifference between the manual and automatic control system stops whether the system isreceiving radio frequency response and control functions, and bus automatic stationapparatus characterized by a receiving radio signals and automated voice broadcastfunction, the controller consists of 51 single-chip, wireless receiver modules, voice player,buttons, LCD display and other components.Campus bus automatic station apparatus of this design with previous stops meansdiffer, the previous bus automatic station apparatus also has a control element coremicrocontroller. But it is on the platform plus an electronic tag, and adds an e-reader aswell as data transmission module on-board systems. Data transmission module and thensend the information to the MCU. Then again MCU control. Electronic tags, there aremany shortcomings, such as replacement of the site is very convenient and easy to signalinterference. Radio module can improve these shortcomings to some extent.But this design, there are many deficiencies need to be improved. We can shut a doorcontrol button on the car system. A button is pressed the microcontroller will control themotor control door opening and closing. Finally, we can add some features to make thedriver of the master keys can be more convenient.
