摘　　要：详细介绍了最新研制的ＧＪ－４型轨检系统的数据处理系统。该系统综合了目前国际、国内轨检系统的优点，以微机系统作为数据处理系统的核心，采用模拟滤波与数字滤波相结合的混合滤波信号处理方式，是“捷联式”的检测系统。该系统在国际招标的轨检车中中标，并已投入生产使用。This paper gives a detailed introduction of the data processing system of GJ 4 Track Geometry Measurement System(TGMS)developed recently.This is a “strap down type” system integrating the advantages of domestic and overseas TGMS,with industrial PC at the core,and adopting a hybrid filter signal processing method featuried with the combination of anologic and digital filtering.This system was awarded in the international tendering of track recording car and has been put into operatioin.Future popularization of the system may be expectied over the Chinese railway network.
