基于GPRS的智能公交站牌系统设计

摘要

To provide people waiting on the bus stop the information about the number of passengers on the bus traffic and distance between the site and the running bus. Design a set of intelligent bus stop system. This system counts up the number of the people gets on the bus and the people getting out of the bus to add up the people on the bus by infrared sensor and uses the hall sensor to measure the distance of having driven. Then, send data via GPRS. Finally display on the corresponding bus stop.%为了给等车的乘客提供所选路线上公交车的客流量和距离该站点的路程信息，设计了一套智能公交站牌系统。本系统通过使用对射式红外传感器对上、下车人数进行统计，进而计算出车上乘客数。使用霍尔传感器测量行车路程。再将所得的数据经 GPRS发送出去，显示在对应的公交站牌上。经过实验证明：本系统的各功能模块均能稳定工作，能够实时显示公交车状态，为乘客选择合适的乘车方式提供了参考，节省了时间，具有良好的应用前景。
