Design of Amusement Equipment (large pendulum) System Based on PLC Controlled
The programmable controller, which can be convenient to use and control the system safely and whose program is more simple than the computer programming and has a strong extension ability and control ability, made up of whose control system has the advantages of reliability and conciseness, makes the PLC control technology in many fields be widely used.
This thesis is based on the design of the PLC (large pendulum) control system. On the basis of the design of the programmable controller (PLC), touch screen, inverter and other equipment, we design a stable, reliable, easy to operation, safe and secure PLC large pendulum control system.
The paper first introduces the programmable controller about its cause, itsdevelopment, its application situation at home and abroad, its working principle and hardware basic component of the programmable controller. Then from the PLC control system of each part of the hardware / software composition, design principle and design requirements starting with, according to the PLC recreation equipment (pendulum) control system design based on PLC and inverter control system design methods and steps, including the control of the overall design of the system, hardware and software design.
The paper mainly analyzes the communication module of RS – 485 and the design method, procedure and process of communication between PLC and inverter. At the same time in the control system with a touch screen, through the corresponding program code and PLC communications, which can make a large pedulun be well achieved the rotation, swing and other action requirements.
