摘　　要：为解决公交站或大型客运站客流信息和车内信息获取不便的缺陷,给予乘客更为舒适的乘坐体验并实现公交管理系统中客流统计,基于STM32单片机,以STM32F103VET6为控制核心,对WiFi探针模块、GPS模块、串口通信模块进行整合,开发设计了检测系统.通过探针模块探测得到乘客MAC地址,经单片机对比去重后通过串口通信收发至宿主机,结合软硬件设计探测公交客流信息,收集的数据借助OD矩阵进行深化处理,以提高数据可视化程度,在方便乘客的同时实现信息的多方交互.In order to solve the defects of inconvenient access to passengers flow information and in-vehicle information at bus station or large passenger station,give passengers a more comfortable riding experience and realize the statistics of passenger flow in public transit management system,based on STM32 MCU,STM32F103VET6 was used as the control core,WiFi probe module,GPS module,serial communication module were integrated,a detection system was developed.The passenger’s MAC address was obtained through the probe module,after deleting duplicate data by single chip comparison,the serial communication was used to send and receive to the host machine,combined with software and hardware design to detect bus passenger flow information.Using the OD matrix,the deepen processing of the collected data was conducted,which can improve the degree of data visualization,facilitate passengers and realize information interaction in all aspect.
