摘要目前投入使用的公交车自动报站装置多种多样,但是都有各自的缺点和局限性。有的地区甚至还在使用简陋的半自动报站装置,更有甚者还没有报站装置。本次设计的校园公交车自动报站装置的核心是单片机校园公交车报站装置主要有手动和自动两种,手动报站系统和自动控制系统主要的区别是有无射频接受和反应控制功能,而公交车自动报站装置特征在于有接受无线信号和自动语音播报功能,控制器主要由51 单片机,无线通讯接收模块,语音播放器,按键,LCD 显示屏等组成。这次设计的校园公交车自动报站装置与以前的报站装置有所不同, 以前的公交车自动报站装置也有核心控制元件单片机的。但是它是在站台上加一个电子标签,并且在车载系统上加上一个电子阅读器还有数传模块。数传模块再将信息发送给 MCU。然后单片机再进行控制。电子标签存在很多的缺点,例如更换站点很不方便与信号容易被干扰。用无线模块就可以在一定程度上改进这些缺点。但是这次的设计还有很多的不足需要改进。 本次设计可以在车载系统上一个关开门控制按钮。按钮一被按下单片机就会控制电机控制车门的启闭。最后本设计还可以再加上一些功能按键来使司机师傅可以更加的便利。58308

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.
