| Abstract: | In order to achieve a high space position precision(4 mm), the two step adjusting method is adopted in the FAST(Five hundred meter Aperture Spherical Telescope). BKX I is selected as the FAST's fine tuning platform which is based on the Stewart mechanism. This paper focuses on the study of the control system of the fine tuning platform. Its hardware formed by "PC+PMAC" takes the mode of open architecture. Its software developed under the environment of "Windows+VB" includes two parts.One is developed by the serial communicating package of Microsoft Inc.——MsComm and is used for communication between BKX I and the upper computer, the other is developed by PtalkDT supplied by Delta Tau Inc. and is for PMAC to execute control command sent by the upper computer. Such a fine tuning system has high reliability in performance and high flexibility in architecture and can be used on the debug experiment of FAST. |
