The invention belongs to the field of wireless sensor networks, and particularly relates to a ZigBee-based traffic flow detection and traffic light duration automatic adjustment method. The method comprises the following steps: a vehicle automatically accesses a ZigBee network when passing through an intersection; the vehicle sends vehicle ID information through a ZigBee transmitting module; a ZigBee receiving module arranged at the intersection receives the vehicle ID information; the ID information and the base station number are sent to a database through GPRS and are stored according to acertain format, wherein the storage data comprises an ID number, a base station number and arrival time, the the traffic flow reaching a certain intersection in a certain time period can be counted from stored data, and the traffic flow can adopt time-sharing hierarchical fuzzy control to automatically adjust the duration of the traffic light.

    本发明属于无线传感器网络领域,尤其涉及一种基于ZigBee的车流量检测并自动调节红绿灯时长的方法。所述方法包括:车辆经过路口自动接入ZigBee网络;所述车辆通过ZigBee发射模块发送车辆ID信息;路口安置的ZigBee接收模块接收所述车辆ID信息;所述ID信息与基站号通过GPRS发送到数据库按照一定格式进行存储;所述存储数据包括ID号、基站号和到达时间;所述存储数据可以统计出某一时间段内到达某个路口的车流量;所述车流量可以采用分时分级模糊调控来自动调节红绿灯时长。
