摘　　要：通过分析地铁运营期间设备管理的特点和故障报修流程,设计了基于PDA(Personal Digital Assistant,PDA)的地铁设备故障报修系统;系统基于Windows CE嵌入式操作系统,采用NXD(Native XML Database,NXD)存储数据,通过WIFI(Wireless-fidelity,WIFI)技术实现数据传输,在服务器端使用线程池技术并发处理大量数据;实践结果表明,该系统能够实现数据的无阻塞传输,解决大批量数据交互时的拥塞问题,加快故障信息流转速度,提高设备故障报修效率,增强地铁企业运营安全。Abstract ： Analyze the metro equipment management features and failure reportrepair process during operating period, design the met ro equipment failures reportrepair system based on PDA （Personal Digital Assistant, PDA）. The system is based on the Windows CE em bedded operating system, with NXD （Native XML Database, NXD） to store data, and achieve data transmission with WIFI technology, pro cessing large amounts of data concurrently with thread pool technology in server side. The practical results show that this system could a chieve nonblocking transmission of data, solves the problem of congestion when large quantities of data exchanging, accelerates the fault information flow speed, improves the efficiency of repair of equipment failure, and enhances the operational safety of metro company.
