摘　　要：准确识别移动台的运动过程是应用无线定位技术获取交通信息的基础。在分析移动台运动特征的基础上,阐述了识别移动台运动过程的原理。通过实际的测试获取了GPS机的时空数据,选择不同的时间间隔,应用标签算法识别GPS机的移动、静止状态,得到了不同的识别结果。试验结果显示,在时间间隔选择得当的情况下,标签算法具有良好的识别结果。Identifying movement process of mobile stations exactly is the base of applying wireless location technology to collect tragic information, Based on the analysis of movement character of mobile stations, this paper expounds its principium of identifying movement process of mobile stations. Labeling algorithm is used to implement the move-or-stay identification of GPS equipment according to the GPS data obtained by factual test, and different results are obtained under different time intervals of sampling, The experiment results show that if time interval of sampling is proper, labeling algorithm can obtain favorable results of identification.
