本文总结了一个紧凑的尺寸车载设备的铁路轨道状态监测的新发展，其次是以前的便携式车载设备的发展。轨道不平整度是根据车身的垂直和横向加速度以及侧倾率来估计的。利用谱峰计算方法从车内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轨道上的故障进行定位。该设备由锂离子电池或外部电源驱动6小时。加速度计、速率陀螺仪和全球定位系统经过重新设计，性能更高。如果需要对轨道波纹进行状态监测，可以在外部添加麦克风。收集的数据通常保存在内部非易失性存储器（SSD）或SD卡中。通信单元通过蜂窝电话将收集的数据传送到数据服务器。紧凑型车载设备提供轨道的定期监测，以确保铁路系统的安全。Language：en
This paper summarizes a new development of a compact size onboard device for condition monitoring of railway tracks followed by a former development of a portable onboard device. Track irregularities are estimated from a vertical and lateral acceleration and roll rate of a car body. Rail corrugation is detected from cabin noise with spectral peak calculation. A GPS system and a map-matching algorithm are used to pinpoint the location of faults on tracks. The device is driven by Li-ion battery for 6 hours or outside power source. Accelerometers, rate gyroscope and GPS were redesigned to give higher performance. One can add a microphone outside if a condition monitoring of rail corrugation is necessary. Collected data are usually kept in an inside un-volatility memory (SSD) or a SD card. Communication unit transfers the collected data to a data server via cellular phone. The compact size onboard devices provide regular monitoring of tracks for sustaining railway system with securing safety. Language: en
