摘要
分布式协同诊断系统,由诊断管理中心、便携式维修终端及诊断中心组成。采用C/C++设计各功能模块,并利用MySQL–API实现在Linux下应用模块与数据库服务器的连接。运行时,PMA先与诊断管理中心互验身份,然后与其建立IPSec连接并发出诊断请求。诊断代理服务器为PMA提供诊断服务,并将相应的诊断中心地址信息及证书返回给PMA。PMA收到信息后与指定诊断中心认证身份并建立IPSec连接,随后发送故障诊断数据,最后由诊断中心将诊断结果直接返回给PMA。
A distributed collaborative diagnosis system-DCDS is composed of diagnosis management centers, portal maintenance aids and diagnosis centers. All functional modules in DCDS are implemented by using C/C＋＋, and MySQL-API is used to access the diagnosis databases in Linux. When DCDS is running, a PMA and a DMC firstly verify the identifications each other, then set up an IPSec connection. Secondly, the PMA sends a diagnosis request to the DMC, theft, a diagnosis agent in the DMC is running to provide the diagnosis service, and sending the DC＇s address and certification information back to the PMA. Thirdly, the PMA and the assigned DC verify the identifications each other, then, set up an IPSec connection by which the PMA could send the fault data to the assigned DC, and the latter would send the diagnosis results back.
