摘　　要：选择TI的Zstack作为研究基础,在ZigBee的OTA技术基础上做了一定的改进,设计出一种多点并发、可靠、高效、低能耗的无线下载解决方案。采用数据压缩技术实现对固件代码数据的压缩处理,提高了该方案的性能,并在基于CC2530传感节点上做了具体的实现。该方案成功地应用于一个具有200多个传感节点的ZigBee网络中,方案的可靠性及稳定性得到了验证。TI′s Zstack was selected as a research base,which improved on the basis of OTA technology established by ZigBee Alliance. A multiconcurrent,reliable,efficient,lowpower OTA solution was designed. also The data compression technology is used in this solution to compress the firmware code data,so as to improve the performance of the application. It was implemented on CC2530 sensing nodes,and was applied to ZigBee network with more than 200 sensor nodes successfully. The reliability and stability of the solution were validated.
