Embodiment one
Fig. 1 is a kind of schematic flow sheet of an embodiment of temprature control method provided by the invention.
The embodiment of the invention, as shown in Figure 1.A kind of temprature control method, including step S110 and step
S120。
In step s 110, thermostatic control section is obtained, the thermostatic control section is [lower limit, higher limit], described
Lower limit is T targets-X, and the higher limit is T target+X, and wherein T targets are target temperature, and X is the one of the scope in constant temperature section
Half.
For example, constant temperature section is 10 degree, T targets are 200 degree, X 5 of target temperature, are the half of the scope in constant temperature section,
The thermostatic control section of acquisition is [195,205].
In the step s 120, temperature controlling step, the is determined according to the higher limit in the thermostatic control section and upper momentum
One temperature spot, and second temperature point is determined with lower momentum according to the lower limit in the thermostatic control section, in the described first temperature
Degree point instruction stops heating, is begun to warm up in second temperature point instruction.
Wherein, the upper momentum is the maximum temperature that temperature rises to after upper the first temperature spot once stops heating
