【摘要】 针对港口卸船机系统的远距离多个控制节点的特点,结合某电厂港口卸船机控制系统介绍了采用多总线系统———GeniusBUS总线和ProfiBUS总线构建的基于PLC的控制系统,其可实现对港口卸船机系统进行综合控制。该系统投入运行后,控制效果良好。对同类电厂控制对象构建控制系统具有参考价值。更多还原

【Abstract】 Combined with the control system of coal-ship unloader in the harbour of one power plant,and directing against the features of a complex control system with far distance and multiple control nodal points of the coal-ship unloader system in the harbour,a control system based on PLC,and composed of multi-bus system,Genius BUS,and ProfiBUS has been presented,then a conprehensive control can be realized by using the said system to control the coal-ship unloader in the harbour.After putting the said system into operation,the control effectiveness to be good,having reference value to establish control system for similar controlled objects.更多还原
