為了確保我國鐵路旅客列車的行車安全，在列車上全部裝載使用了新型KAX-1旅客列車行車安全監測診斷系統，對系統的車載安全監測診斷、無線通信和地面數據管理與專家等3個硬件子系統的硬件組成及特點進行了分析與研究，并對檢測系統的列車基礎制動裝置、轉向架、防滑器的基本原理進行了詳細的分析與研究；整個系統采用了較為先進成熟的技術，應用軟硬件可靠性設計，功能級監測節點的傳感器免標定免維護；地面數據庫與專家系統的數據存檔、查詢、診斷、聯網功能為車輛應用和管理部門提供了一個車輛應用管理、動態質量控制的信息化技術平臺；系統投入使用后，大大提高了鐵路旅客列車的行車安全，判斷故障的正確率在95%以上，在我國鐵路行車安全方面有很大的發展前景，大力推廣使用。

Abstract:

?In order to ensure the traffic safety of China’s railway passenger train traffic safety， all of China’s new railway passenger trains loaded used the KAX-1 passenger train traffic safety monitoring and diagnosis system， hardware composition and characteristic of paper-board safety monitoring system diagnosis， wireless communications and ground-based data management and experts was analyzed and researched， and the train detection system foundation brakes， bogies， the basic principles of anti-skid device were carried out a detailed analysis and research； the whole system used a more advanced and mature technology， and applied software and hardware reliability design， function-level monitor calibration-free sensor nodes were in maintenance-free； ground-expert system database and data archiving， query， diagnostics， networking capabilities provides a vehicle application management， dynamic quality of the control of information technology platform for the vehicle application and management department; after the system put into use， it greatly increased rail passenger train traffic safety， the correct rate of judging failure is over 95%， it has great development prospects in the aspect of train traffic safety， it is widely popularized to use.
