Abstract：To solve the poor generality problem of monitoring instrument platform in wireless sensor network, this paper will combine reconfigurable virtual instrument technology and WSN, develop a set of multi-function monitoring instrument platform to adapt WSN characteristic by using Visual studio software.This instrument not only can compatible various nodes to facilitate function expansion, but also realize different monitoring system function by replacing component according to different measurement task needs.At last, based on the actual application, we build the wireless instrument platform of equipment in mine hoist room to realize the instrument system online reconstruction.
