The Design of Temperature’s Measurement and Control System for Blow Film Extruder
Abstract: This paper presents a computer-based monitoring control system for a temperature control and test, The system can simultaneously display the various parameters of the control device and control it to start and stop automatically for manually and warning. Based on the presentation of control system structure ,the paper analyses the feature of this temperature control system and give an account of designing a practical PID control, thus improving the accuracy of measurement and control of the temperature. It has the features of a low prices、good performance、low power dissipation、small size、easy operation and enjoy the stability while working in a low frequency. So the system is proven to be simple、practical、and reliable.
