The work aims to design an ARM-based gravure printing electronic equipment drying system controller to provide a higher and accurate drying temperature for the printing of electronic products. The constant current source temperature measurement circuit of PT100 temperature sensor was built for the real-time measurement of the temperature inside the oven. The collected temperature signal was transmitted through AD conversion to the control chip for analysis and processing. The control chip controlled the on-off switching of heating tube through the solid-state relay. The fan was controlled by the frequency converter to achieve the control over the temperature inside the oven. Experimental results showed that the temperature measurement range of the controller was 0~205 ℃, and the measurement accuracy could be 0.1 ℃. Through the synergistic effect of the heating pipe control and the fan control, the inside of the oven can always maintain the preset temperature to meet the requirements of the drying process of printed electronic products.
