基于S7_300PLC的行车电机状态数据采集系统设计

Design of date acquisition system for crane electromotor on S7_300PLC

针对炼钢厂行车运行过程中电机状态检测控制技术存在的问题,本文提出一种基于PLC和组态软件的电机状态检测方案。该检测系统采用S7_300系列CPU模块和I/O模块组成现场工作站,上位机采用工控机和组态软件,对采集的数据进行实时监测与管理。

Due to current detection control technology for motor position of the steel mill crane in the operational state, a motor state detection scheme based on PLC and configuration software is proposed. The CPU modules and I/O modules of S7-300 series are employed to form the workstation. In order to monitor and manage the acquisited data in real-time, the industrial PC and configuration software are employed to form the host computer.
