摘　　要：通过开发发动机信息管理系统后台数据的异地备份软件,介绍了以Delphi 10Seattle为开发工具,应用Indy组件,多线程方式实现客户端向服务器端发送备份指令,完成数据的备份、加密压缩以及向异地客户端推送数据,以客户端完成压缩数据的接收结束异地传输,同时服务器端实时向不同客户端发送执行过程信息。因发动机数据量较大,备份和传输时间较长,在异地客户端采用同步进度条显示。软件设计采用TCP可靠传输,提高数据传输的安全性。Software for background data offsite backup of liquid rocket engine informationmanagement system is developed. Based on Delphi 10 Seattle as developing tool and lnOy component, the data backup, encryption, compression and data pushing to offsite client-side are realized by sending the backup instruction from customer end to server end in multithreading mode. The data offsite transmission is finished at the end of the compressed data reception of client-side. The information in executing process is sent to different client-sides in real time by server end. Transmission of the data backup needs a long time period due to large size of the engine data, so a synchronous progress bar is displayed at each client-side. The reliable TCP transmission is adopted in the software design to ensure the safety of data transmission.
