摘要:本设计是用AT89C51单片机和红外感应器为主要器件设计的公交车智能防超载系统。通过红外线发射和接收器接收来对上下车乘客数进行检测,把信息实时传送给单片机,然后单片机对接收到的数据做进一步分析计算处理,若检测结果比预设的值大,就会产生一高电平信号,然后这个高电平信号进入单片机的引脚,立即会产生一脉冲信号,然后通过公交车广播发出预先录制好的语音报警“此车超载”并实时LED显示,实现超载提示。39351 毕业论文关键词:公交车;红外传感器;超载;自动报警
Overload Protection Intelligent Voice Prompt System Delivery
Abstract:This design is used AT89C51 controlled and infrared sensors for the design intelligence bus main device overload protection system. Through the infrared transmitting and receiving device on the bus carrying passengers numbers were detected the results real-time transfer to the controlled, and then by the MCU of the received data do further analysis and calculation, the comparable treatment, if the current number of people than the default value large enough, it will produce a high level signal, and the high level signal into the controlled pin, will immediately generates a pulse signal, and then by bus broadcast a per recorded voice alarm of the vehicle overload and real-time LED display. To avoid overload.
