Abstract:  In order to reduce the embedded system upgrade and maintenance costs effectively, according to the embedded equipment storage structure and updating principle, a remote online  firmware updating technology based on ZigBee was proposed, including  in application programming(IAP) online upgrade principle, improvement of ZigBee protocol, flash zoning on chip, response mechanism, breakpoint resuming and sliding window protocol Combined with remote online firmware updating strategy  used in LED street lamps energysaving system, a technological process of the remote online firmware  upgrade was  described. The research result proves that this design scheme has a simple and easy to use characteristic Beside, it helps to reduce the hardware cost and communication error rate, has vast applied foreground
