The intelligent temperature control box is a device that continuously maintains the required temperature value. It mainly detects the temperature of the heating channel through the intelligent computer chip (MCU) in the watch core, and then processes the data inside the intelligent computer. The appropriate proportional current value is output to achieve the purpose of temperature control. The accuracy and stability of the temperature control mainly depends on the following important factors:

1. Temperature measurement: sampling period parameters, data filtering processing decision Temperature, measurement circuit temperature compensation, etc. determine the temperature measurement accuracy;

2.PID control: The output current ratio is reflected by regulation, the relevant parameters have proportional segments, and the integral time is differentiated;

3 .PIDD control: Through the phase angle control, the relevant parameters have proportional segments, integration time, and differential time;

4. Automatic adjustment: By analyzing the heat of the heating wire and the heat of the mold Number, provided that the dominant factor function (with latent heat and heat dissipation, no matter how environmental changes it will help to accurately control the temperature).

5. Output mode: The output mode of the intelligent temperature control box can be changed according to the environment.

.SSR (PIDD) mode: accurate temperature control can be achieved, but the noise ratio of the power supply is PWM. The pattern is much larger.

.PWM (PID) mode: The current noise is small, but the control ability for a specific temperature is worse than the SSR mode.
