| Abstract: | In order to enrich the vocational PLC training course content and students＇ manipulative ability, this paper introduces an electric-heating temperature automatic control training device based on PID control principle, and uses $7-200 PLC as the main control device. Through the temperature sensor and transmitter, the temperature will be put into the PLC controller. The PID program will figure out the result through comparing with the set value, and the final result will be put out by SSR solid state relay. At last, the goal of controlling the temperature can be reached. Though the actual test indicates that the device has the characteristics of stable operation, convenient operation, low cost, and good training effect. |
