以嵌入式技术为基础，采用单片机及串口通信技术，开发基于蓝牙的路网平均行程时间检测器，实现自动采集车载蓝牙M AC地址并配时和数据存储的功能。通过场地测试确定了设备漏检率的平均大小、与速度的关系及初次检测点位置的分布规律。测定了设备的检测精度，并对平均速度、检测数、配对数等因素进行了分析；通过 t检验、曼惠特尼U检验及沃尔德沃尔福威茨（W-W ）检验验证了设备数据的可靠性；通过实地测试验证了设备的可用性和实用性，并根据测试结果，提出了设备存在的一些不足以及后期改进的建议，为蓝牙检测器的后续研发奠定了基础。

A Bluetooth-based travel time detector is designed by using serial communication and embedded technolo-gy .The device can automatically collect the Bluetooth MAC addresses and corresponding time stamps and then save the data on a local storage device .Laboratory studies are used to study the relationship between average undetected rate and vehicle speed as well as the locations of first-time monitoring sites .The detection accuracy of the device is also tested through field trips against the following factors :average speed ,detection rate and number of the paired devices .The T-test ,Mann Whitney U-test and W-W test carried out all indicate that the device is reliable for travel time detection .In ad-dition ,the shortcomings of the device and the recommended improvements are also summarized at the end of the paper , which provides basis for further research on Bluetooth detector .
