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.
