A pre-drive method based on Zigbee was proposed for LAMOST fiber positioning, which was adopted the pattern of wireless communication. Comparing with traditional control way of wire drive, it can reduce the number of external antenna more than 95%, furthermore, the difficulty of installation was minimized by saving the space on the back of focal plate. A experimental system, whose node point was based on chip microcomputer with the function of Zigbee, was designed to prove the system feasibility. The system of localization and reset for fiber positioning units can be used in first-phase experiment, and the host computer can make the further decision by employing of the feedback information of zero point from it.
