面向分布式地震仪的应用升级更新软件设计

Design of Application Upgrade Software for Distsributed Seismograph

针对分布式地震仪的应用升级、配置更新的需求以及传统下载烧写和网络挂载更新程序的方式存在耗时耗力、操作难度大等问题展开研究。提出一种基于UDP和FTP协议、面向分布式地震仪的应用升级方法,给出软件实现过程。实现了WindowsPC机端的C#发送软件和嵌入式Linux采集站端的C解析软件,并通过中央服务器实现采集站拓扑获取和消息文件转发的功能。用户通过发送软件批量上传固件程序包和消息包,通过三机交互实现仪器的应用升级与命令控制。测试表明,设计的软件显著减少了重复烧写程序和网络挂载的操作,操作便捷、可靠,实现仪器节点的批量更新,降低了仪器维护难度。

For the application upgrade and configuration update of distributed seismograph, as well as the traditional way of downloading and burning and network mount update program has many problems, such as time consuming,operation difficulty and so on. Therefore, it proposed an application upgrade method for distributed seismograph and its software implementation process which is based on UDP and FTP protocol. The C# sending software of Windows PC and the C parsing software of the embedded Linux station were realized, and the functions of acquisition station topology acquisition and message file forwarding were realized through the central server. Users can upload the firmware and the message package by sending software, and then realized application upgrade and command control of the instrument through three-machine interaction. Tests show that the software reduces the operation of repeated erasable programming and network mounting, and the operation is convenient and reliable, the batch update of instrument node was realized, the difficulty of instrument maintenance was reduced.
