In the laboratory, in view of the requirement of high sensitivity and the problem of external interference on continuous variables coherent optical communications platform, the remote intelligent control system is designed based on LabVIEW and the AVR microcontroller. The system communicates with AVR microcontroller through the RS232 standard serial interface, which uses LabVIEW8.2 remote front panel technology, serial port VI and data acquisition board. The remote intelligent control of the power supply of various electric circuit modules is realized in the coherent optical communications system. The power supply systems are protected effectively and the disturbance is reduced.
