Design of Control System for Diverse Glass Grinding Device
Jingzhao Li · Control Engineering of China · 2010
The design of the glass grinder with seven kinds of flower types is discussed.The control circuit is made up of S7-200PLC and HMI PWS1711.The PLC completes the functions of collecting all kinds of switch signals,rotated angle of milling wheel and measurement of milling wheel,as well as the parameter calculation and output control etc.Several menus are designed in human-machine interface(HMI)with some functions such as the real-time monitoring and the parameter setting for grinding glass.The grinding process,the control circuit,the grinding pattern of PLC,and the HMI software design are analyzed.The glass grinder has advantages of high grinding precision and multi-type of grinding.
