摘要
电动绞车常用于海洋仪器的吊放、回收以及信息传输,是人类对海洋资源勘探和开发过程中必不可少的设备。当仪器吊放海洋深度达到10 000 m以上时,缆绳的质量会远远大于设备的质量。针对仪器数据传输的光电复合缆绳的张力要求在一定的范围内,文章提出了一种电动绞车控制方案。该方案采用PLC控制核心,以交流伺服系统作为驱动单元,采用变频控制方法实现对绞车的变转矩恒张力控制。该设计对相同类型的电动绞车设计有着非常重要的指导和借鉴作用。
Electric winches are commonly for dipping, recovery of oceanographic instruments and information transfer, which is a necessary equipment in the process of marine resource exploration and development. When the instrument is dipping at ocean with depths of more than 10 000 m, the weight of cable is far greater than the weight of instrument. The optoelectrical composite cable tension for device data transfer requests within a certain range. An electric winch control scheme is proposed. Using PLC control core and AC servo system as the drive unit, the variable frequency control method is used to control the variable torque constant tension winch. For the same type of electric winch design, the design method offers significant guide and reference.
