基于无线分包传输的气象站固件无感升级方法

Non-feelable upgrade of automatic weather station based on wireless packet transmission

摘要:

针对野外运行的自动气象站具有嵌入式固件升级的实际需求,设计了一种基于无线公众网传输的自动升级方法。该方法在中心站软件和采集器之间实现升级文件分包可靠传输,中心站软件的在线升级控制系统具有自动检查采集器版本和主动升级功能,断点续传机制保证下载过程具有较高的容错能力,无感升级策略避免了升级过程对设备作业任务的影响。测试结果显示该方法实现了设计的目的,对于野外广泛布设的自动气象站的在线升级具有使用价值。该方法也可以为其他野外观测设备的自动化在线升级提供参考。

Abstract:

For automatic weather station operating in the field with actual requirements of embedded firmware upgrade, an automatic upgrade method based on wireless public network transmission is designed. The method realizes the reliable transmission of the upgrade file in the wireless network environment by the online upgrade control system and the embedded firmware interaction program. The breakpoint transmission mechanism ensures that the download process has high fault tolerance. And non-feelable upgrade strategy lets the automatic weather station operate normally throughout the upgrade process. The test results show that the method achieves the purpose of design and has the use value for the online upgrade of automatic weather stations widely deployed in the field. This method can also provide reference for automated online upgrade of other field observation equipments.
