Fiber positioner is the key component of multi-object spectral survey telescope. In LAMOST, 4,000 fiber positioners accept DC voltages for power from 64 switch power sources. The working conditions of fiber positioners need to be monitored in case that over-current phenomenon damages positioners and raises the temperature of positioners and focal plane which can seriously damage position accuracy. Considering that positioners being used in LAMOST cannot change their electrical properties, this paper implemented a power monitoring and control system based on RS485 bus and LabVIEW to avoid over-current phenomenon in LAMOST. CC6920, distributing voltage circuit and DS18B20 are used to monitor the output current, voltage and temperature of the power source respectively in real time. The monitoring values are shown on LCD and returned to IPC to be saved. When the value exceeds the rated value, relay will cut off the power and a mail will be sent to staff. The validity of the power monitoring and control system is verified by experiment in the actual environment. The preliminary results show that the system has good stability and the response time is less than 70ms. The system which has been used in LAMOST is low in cost, fast in response, convenient in use and expandable.
