| 摘 要： | 随着嵌入式技术的不断发展，智能设备逐渐成为研究热点，解决智能设备软件版本升级问题至关重要。节点软件升级系统一般分为主计算机、网关节点和传感器节点3个部分。主计算机通过串口将要更新的软件代码发送到网关节点，网关节点通过无线传感器网络传递软件代码到传感器节点并控制节点，以完成新版本升级。研究了CC2430芯片所适用的软件升级系统。主计算机使用基于C#语言的窗体应用程序，将代码的iHex文件分割成可变长数据包，提高主机和网关节点之间的代码传输速率。实验证明，该方法有效减少了主机与网关节点的代码传输时间，提高了写数据效率，可广泛应用于智能家居及医疗监测等领域。

| Abstract: | With the continuous development of embedded technology， smart devices for application chips have gradually become a hot field of research， and it is very important to solve the problem of software version upgrade on smart devices. A node software upgrade system can be generally divided into three parts： upper computer， gateway node and sensor node. The host computer transmits the software code to be updated to the gateway node through the serial port， and the gateway node sends the software code to the sensor node through the wireless sensor network and controls the node to complete the new version upgrade. The software upgrade system applied to the CC2430 chip is studied. The form application that is based on the C# language is used to divide the iHex file of the code into variable-length data packets， which improves the code transmission rate between the host computer and the gateway node. The experiment proves that the method effectively reduces the code transmission time of the host computer and the gateway node， improves the efficiency of writing data， and can be widely used in the fields of smart home and medical monitoring. |
