| Abstract: | Introducing a middle-frequency inductive oven temperature monitoring system used for aluminum rod heating,it can detect the temperature of cooling water for the oven's inductive coil.The temperature control system including two set of infrared transducers and 64 semiconductor integrated temperature switches.The analog signals are transferred by 4-20 mA current loop and the switch signals are transferred by RS-485 data bus in time dividing and scanning.All of them are gathered by data interface board in which assembled with the A/D converter and the data buffer.The output signals of interface board are displayed on the monitoring computer through RS-232C serial interface.The temperature monitoring system will display the system parameter and temperature parameter by switching symbols and swinging points in the form of states conversion or numeral indication. |
