5. The method of claim 1, further comprising, after controlling the device to make a temperature adjustment by the temperature-controlled PID parameter until the target temperature is reached:
and switching to the standard PID parameters, and controlling the equipment to keep the target temperature to operate by using the standard PID parameters.
6. The method as recited in claim 1, further comprising:
when a soft start command signal is received, the device is controlled to carry out temperature adjustment with a soft start temperature change slope through a preset soft start PID parameter until reaching a soft start holding temperature for a preset time.
7. The method of claim 1, further comprising, prior to obtaining the standard PID parameters:
a rejection disturbance signal is input to prevent non-commanded data skew.
8. A temperature control apparatus, comprising:
the target determining module is used for determining the target temperature reached by the equipment required by the user and the required target temperature change slope;
the standard parameter module is used for acquiring standard PID parameters, wherein the standard PID parameters are PID parameters which are obtained through temperature self-setting determination and control the equipment to operate at the target temperature;
the temperature control parameter module is used for determining a temperature control PID parameter for controlling the equipment to change temperature according to the target temperature, the target temperature change slope and the standard PID parameter;
and the temperature adjustment module is used for controlling the equipment to adjust the temperature through the temperature control PID parameters until the target temperature is reached.
9. A temperature control device comprising a memory and a processor;
the memory is used for storing programs;
the processor is configured to execute the program to implement the respective steps of the temperature control method according to any one of claims 1 to 7.
10. A readable storage medium, on which a computer program is stored, characterized in that the computer program, when being executed by a processor, implements the steps of the temperature control method according to any one of claims 1-7.
