.12.5 M Heat Setting Machine Computer Control System

The wide breadth polyester mesh has become more and more important in modern industry. After been weaved, the fabric were need to go through heat-setting process for stabilize shape and improve the stress. The heat-setting equipment was used to stabilize fabric specially.The heat-setting computer control system is an advanced distributed SCADA system which involves temperature control, frequency speed control, serial communications, and computer and touch terminal.SCADA(Supervisor Control And Data Acqusition) is usually made up of distributed data acquisition equipments as well as data process and visualization systems on which operator can operate field equipment, view the trend and record alarms.The control system of the heat-setting equipment is comprised of several parts described respectively as follows1. The temperature control system. The AL808 meter which has the ability of automatically tune PID parameters of the system was very successful in tune the heat-setting system parameters.2. Speed adjustment system of AC motor. Using the transducer, we have get very good effect in four motor speed adjustment.3. Synchronization of stretching is accomplished by synchronizing the speed of two stretching motor. This system employs a high speed counter unit to get the stretching displacement error used as the feedback of the fellow motor.4. The tension control system employs FUZZY-PI control algorithm to gain good control effect.5. Supervisory control system which were developed from KingView's vision 6.5 was successful in monitor and control task.This computer control system has referenced foreign advanced technology. The automation degree and control precision has been greatly improved because using of high precision component and advanced control arithmetic.The project would contribute to our country's wide heat-setting equipment.
