本文综述了先进的铁路状态监测“探测车”系统的发展。研制了一种便携式轨道状态监测系统，该系统易于安装在运营车辆上。在该系统中，轨道的不平顺估计由车体的垂直和横向加速度。利用速率陀螺仪计算车体的侧倾角来区分线路不平顺和水平不平顺。通过谱峰计算可以从车厢噪声中检测出钢轨磨耗。利用GPS定位系统和地图匹配算法对故障进行了定位。使用在役车辆进行了实验来评估所开发的系统。结果表明，该方法可以有效地估计钢轨不平顺和钢轨弯曲的情况。该系统可用于驾驶员操作状态的监测。
This paper summarizes the development of "probe-vehicle" system for advanced railway condition monitoring. We developed a portable condition monitoring system for track which is easily set on in-service vehicle. In this system, irregularities of rail are estimated from vertical and lateral acceleration of car body. A roll angle of car body, which is calculated using a rate gyroscope, is used to distinguish irregularity of line from irregularity of level. Rail corrugation can be detected from cabin noise with spectral peek calculation. GPS system and map matching algorithm localizes the fault on track. Experiments using in-service vehicle were carried out to evaluate the developed system. The results show that the condition of rail irregularity and rail corrugation can be estimated effectively. It is also shown that the system can be applicable for monitoring driver's operation condition.
