Abstract
In control system, have to control the system, calculator control system after the electric appliances to control the system with the PLC, in the different and applied realm, each control system has got each from of advantage, but along with change horaryly, technical development in science, control the system also faces at the higher direction develops, the control technique that fall behind is necessarily will was replaced by the advanced viable control technique.Because PLC control system with control system and tiny machines the control after the electric appliances the system compare, having the design, install, connect the line and adjust to try the workload small, research to manufacture the period short, the dependable is high, the anti- interference ability is strong, breaking down the rate low, request to be low to the work environment, support a series of advantage in etc. in convenience, therefore, have become the head that domestic and international machine bed control object choose to control the project.Research to manufacture the good control in function in a technique system for the machine bed control object design, for machine bed that increases the whole technique function controls the object to say that have the very important meaning.This text aims at this lesson a control for, choice PLC control system conduct and actions machine bed controling object project exactly, this control to machine beds that promote the whole technique functions the object can rise good function.
In according to PLC machine bed control system design, designed the total project in system in control in PLC in automatic line in bed in machine, proceed soft, the design of the hardware, and gave to realize project.To according to the PLC machine bed control electrical engineering in the system electric appliances control circuit presses with the liquid PLC that spreading and moving the design process controls the system makes to expatiate.Control the design part of the circuit in the electric motor electric appliances, expatiate main electric circuit in electric motor and its electric applianceses control the design process of the electric circuit, giving the choice result of an electric appliances for these two electric circuits a piece.Press to spread to move the design part that PLC control the system in the liquid, expatiate the design process that PLC I/ O connect the line diagram, give the PLC and its input/output a design for of choice result, in detail expatiating PLC customer procedure process, among them the design process that include to use the single automatic procedure, whole machine in half in a procedure, whole machine in procedure, single machine to the Public procedure automatically expatiates, and the trapezoid diagram that gave above all procedures with instruction form.
