Design and implementation of a standardized sensor network node based on virtual instrument and IEEE1451

It´s the trend that sensor network become more standardized and unified as internet of things develops continuously. Aiming at resolving the problems arising from variety of sensors type and interface, this paper presents a design idea of a standardized sensor network node based on virtual instrument and IEEE 1451 standard, and expounds the realization of this sensor node. A concept of sensor node user program API is introduced to facilitate upper sensor network or host interacting with this standard sensor node. Test results show that this sensor network node could meet the practical application.
