电机群网络管控一体化PLC-SCADA设计及应用

摘要

Considering the characteristic of industrial production process such as large muraber of machines, complex sequential logical, high drive control demanding and distributed in different territory. The paper uses merits of PLC and SCADA and inverter in the scope of industry control. The machines group drive system is structured as PLC - SCADA using network and PROFIBUS - DP and RS -485, and implements machines group control and management via network and bus. The results of practical application in multi-drive dyeing and printing machines verify the reliability and efficiency of the design strategy of system.%针对电机数量众多、时序复杂、传动要求高、地域分布分散等工业生产过程,利用PLC、SCADA、变频器在工控领域中的优点,设计了一种基于网络和PROFIBUS-DP、RS-485总线技术的电机群网络管控一体化的PLC-SCADA系统.借助网络和总线实现对电机群传动系统的管理和控制.通过在纺织印染机构多单元电机传动中的应用,实践证明该控制方案可靠、有效.
