摘要
针对目前交通运输中客车超载问题,以PIC系列单片机为核心,采用反射式光电传感器实现上下车人数的逻辑时序判别,对采集到的信号进行处理,当客人超出一定数量时,发出报警信号和语音提醒,并自动关闭发动机,从而实现智能化的过程控制。实验表明该系统减缓了交通控制压力,提高了交通运输能力。
In view of the current transport bus overload problem, choosing PIC microcontroller series as the core, using reflective photoelectric sensor to implement the number of disembarks sequential logic and distinguish it, processing the fight acquisition signal. When passengers number exceeds reasonable range, there will be a warning signal and voice reminders, and the engine will shut down automatically, and realizing intelligent process control. Experiments show that the system alleviated the pressure of traffic control and improved the capacity of transport.
