Hydraulic Carrying Manipulator Control System Based On PLC

Industrial robot control has developed rapidly and has been given priority in the domestic industrial production automation field.Robots play an important role in this field.Large manipulators mainly perform important tasks such as handling,palletizing,and assembly in heavy-duty equipment;small and medium-sized robotic arms mainly perform key tasks such as welding,painting,and inspection in light-load equipment.Small and medium-sized robots have the characteristics of small size,light weight,high precision,and precise control.In addition,the small and intelligent degree of the control system is getting higher and higher.Make the use of small and medium-sized robots wider.This paper has studied the PLC control system and industrial computer monitoring system.Specifically includes the following aspects:(1)The control requirements of the industrial robot are analyzed:the control module is made by German Siemens S7-200 PLC and KingView are composed of two parts;the drive module is composed of servo drive and pneumatic components;the feedback system is completed by the sensor components.(2)Designed the motion control system and human-machine interface configuration.The hardware is mainly Siemens S7-200 PLC is used as the bottom circuit center.It uses optoelectronics and proximity sensors to collect position signals.It collects motion requirements through panel button switches.STEP7-MicroWIN V 40 SP9 software is used to write the control program in a modular programming mode.The control program uses manual modules and automatic modules to implement predetermined functions according to the control requirements.In order to improve the reliability of the program,the robot operation program is designed into four working modes,Single-step,single-cycle,continuous automatic,manual debugging four operating modes,while ensuring that each mode of work is not affected by the state of other operating modes,the industrial computer monitoring system is based on the configuration king,through equipment configuration,The parameter setting and the design of the man-machine interface,real-time interaction with various data states of the PLC,so as to intuitively display the movement state of the manipulator to the user.(3)The control system was debugged,the debugging results were displayed,and the problems in system operation were analyzed.
