摘要
用电信息采集终端负责电能数据的采集和双向传输,是用电信息采集系统的核心设备。在现场使用中,经常需要对终端软件进行升级完善。但是,目前对于终端软件的升级缺乏统一的标准和平台,终端升级处于无序状态,影响采集系统正常运行。提出和实现一种支持断点续传和身份验证的终端软件升级规约。同时通过与采集系统建立通信接口,构建统一升级平台。该平台解决了升级文件断点续传的问题,避免了信道来回切换导致的连接中断,实现了批量升级文件下发。通过实践测试证明,该平台不仅提高了终端软件的升级效率,同时降低了升级过程中的丢包率,适用于复杂环境下的大批量终端升级。
Power information acquisition terminal is the core equipment in power information acquisition system in charge of power data collecting and two-way transmission. The terminal software usually needs to be upgraded in on-site application. However, there lacks any criterion and platform for terminal software upgrading. The disorder state of the terminal upgrading impacts the normal operation of the acquisition system. We present and implement a terminal software upgrade protocol in the paper, which supports the broken-point continuously- transferring and the authentication. At the same time we construct a uniform upgrading platform through establishing the communication interface with power information acquisition system. This＇platform solves the problem of broken-point continuously-transferring of the updating files, avoids the connection interruption caused by channel switch, and realises the batch issuing of update files. It is proved through the practising test that this platform improves the upgrade efficiency of terminal software, and also decreases the packet loss rate during the updating process as well, it is suitable for the bulk terminal upgrade in complex environment.
