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(jiān)測(cè)診斷系統(tǒng)，對(duì)系統(tǒng)的車載安全監(jiān)測(cè)診斷、無線通信和地面數(shù)據(jù)管理與專家等3個(gè)硬件子系統(tǒng)的硬件組成及特點(diǎn)進(jìn)行了分析與研究，并對(duì)檢測(cè)系統(tǒng)的列車基礎(chǔ)制動(dòng)裝置、轉(zhuǎn)向架、防滑器的基本原理進(jìn)行了詳細(xì)的分析與研究；整個(gè)系統(tǒng)采用了較為先進(jìn)成熟的技術(shù)，應(yīng)用軟硬件可靠性設(shè)計(jì)，功能級(jí)監(jiān)測(cè)節(jié)點(diǎn)的傳感器免標(biāo)定免維護(hù)；地面數(shù)據(jù)庫與專家系統(tǒng)的數(shù)據(jù)存檔、查詢、診斷、聯(lián)網(wǎng)功能為車輛應(yīng)用和管理部門提供了一個(gè)車輛應(yīng)用管理、動(dòng)態(tài)質(zhì)量控制的信息化技術(shù)平臺(tái)；系統(tǒng)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(fā)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.
