电机试验站机组拖动控制系统设计与应用

Design and application of distributed unit control system in motor test station

在电机型式试验过程中,各机组的工况与运行控制较为复杂,一般采用人工单机控制,因此很难满足试验测试的要求。介绍一种由触摸屏、PLC和单片机构成的分布式机组拖动自动控制系统,利用上位计算机将各机组拖动子系统集中管理,可方便实现单机闭环控制和机组群控。该系统具有良好的人机界面,操作方便、结构简单,并应用于某中型电机试验站计算机自动测试系统中。实际应用表明提高了电机试验的自动化程度,使测试数据更加客观准确。

The condition and operation control of motor units in motor type test is quite compli-cated. The manual control of single unit is normally used,which can hardly meet the test require-ments. A distributed unit control system composed of touch screen,PLC and single-chip microcom-puter is introduced. The superordinate computer manages all subsystem to realize single-unit close-loop control and multi-unit group control. The system has friendly MMI,simple structure and easyoperation. Its application in a middle-sized electric motor test station shows that the test automation is improved and the test data more objective and accurate.
