摘要
根据FAST主动反射面需求评估了对促动器性能的要求,依促动器评估参数需求设计了针对电流、功率、温度、负载、位移、限位信号的监测系统,确定各监测信号传感器选型,完成监测系统的组装制作,并将其应用于实验,实现促动器的在线监测功能以及促动器无人值守实验,针对以往促动器实验时人工巡检故障的离线监测有很大改进,在精度以及历史信息记录上都有质的提高,进行了长期的促动器调试与监测。
There are high standards for the actuators of the Five-hundred-meter Aperture Spherical Telescope （FAST）. In the past tests, we usually only used inconvenient human inspection for recording states of the actuators. We assess the requirements on the actuators for the FAST. For testing the actuator we have further designed a monitoring-management system that can measure the current, power, temperature, load, displacement, and limit of an actuator. The system can automatically monitor and record, avoiding the inconvenience of human inspection. We chose appropriate sensors for the system and fabricated it following the structural design. We have tested the system using certain equipments. This system has achieved online monitoring of the actuators and successfully passed tests of supervision of the actuators without human intervention. The tests have generated many data showing the reliability and effectiveness of the system. In addition, the system has dramatic improvement in accuracies and maintenance of historical-information records. Long-term tests of the system have shown its satisfactory performance.
