Paper Abstract

The 2225 actuators are the main and key control devices for the deformation control of FAST (Five-hundred-meter Aperture Spherical radio Telescope) reflector. The control behavior of the reflector deformation such as tracking and scanning, is implemented by the central coordination of the actuators. For each actuator, various operation state data should be uploaded to the monitoring center on time. The actuators are controlled from the upper computer in the control center and by the PLC in the relay room. OPC protocol is used in the acquisition and control process. OPC protocol is configured to set related variables. There are significant importance for the data acquisition of the actuators of FAST main reflector. The results can be used to analyze the life of the components of the actuator. They can also be used to monitor the operation status and to analyze the reason of failure, which may be of great help to the function extension, improvement and upgrading.
