摘　　要：以MSP430F149单片机为例,针对无线传感网络中节点软件维护与更新成本较高的难题,设计了一种无线传感网络节点软件远程更新方法。通过程序文件差异比较、变格式传输和数据压缩提高了远程更新效率,通过程序冗余存储和强制更新提高了远程更新的可靠性。经过高速铁路现场应用情况表明,该方法可显著降低节点维护更新成本、远程更新稳定可靠,适于推广。Taking MSP430F149 microcontroller for example, aiming at the problem of high costs of nodes software mainte- nance and improvement in Wireless Sensor Network, a remote update method for node software is designed. The remote update efficiency is improved through differences comparison of program files, transform transmission and data compression, and the remote update reliability is improved through program redundant storage and force update. Field test in high speed railway shows that the method can remarkable reduce the node maintains cost, and the remote update is stable and reliable. It is suitable for promotion.
