基于LoRa的终端代码高效更新方法

LoRa-based terminal code efficient update method

针对现有无线代码更新方法存在控制开销冗余的问题提出一种新方法,包含更新数据合并确认和更新结束判断两种新机制。同时,基于LoRa(Long Range)技术和IAP(In Application Programming)技术设计了一种更新数据高效传输的终端代码更新系统,该系统由PC机、LoRa控制模块以及LoRa终端模块三部分组成,并基于该更新系统对提出的更新新机制进行了验证。测试结果表明,文章提出的无线代码更新新机制能够有效节省控制开销和缩短终端节点的总体更新时间。

Aiming at the problem of redundance of control overhead in existing code updating methods, a new method is proposed which includes update data merged confirm mechanism and end-of-update judgment mechanism. At the same time, a terminal code update system that update data efficiently based on LoRa and IAP is designed, which is composed of PC, LoRa control module and LoRa terminal module. The new update mechanisms are verified based on the update system, test results show that the new wireless code update mechanism proposed in this paper can save control overhead and shorten the overall update time of end-node.
