Abstract

The invention relates to a multi-temperature-zone temperature control system and a control method thereof. The control system comprises a plurality of heating units, a feedback signal acquisition unit, a correction processing unit and a control signal formation unit. With the multi-temperature-zone temperature control system and the control method, the change on system temperature rise characteristic generated due to manual factor in a manner of adopting the control signal formation unit influences whole heating process can be avoided, so that the mutual influence by correction factors and automatic control parameters can be further avoided, and the adjustment difficulty can be lowered; the temperatures of a plurality of heating zones can surely rise simultaneously, mutual thermal interference among the heating zones can be reduced, and the temperature can be fast converged and achieve a constant state; and in addition, the number of the feedback signal acquisition units can be decreased, and further the structure of the temperature control system can be simplified.

Description

technical field [0001] The invention relates to a temperature control device and a temperature control method, in particular to a multi-temperature zone temperature control system and a control method. Background technique [0002] In the prior art, multiple heating units of the heater heat multiple heating zones. The heating of multiple heating zones by each heating unit of the heater is usually controlled by a closed-loop automatic control (PID) unit. In order to eliminate the temperature difference between each heating zone, the automatic control unit will separately adjust the heating of each heating unit, so as to make the temperature of each heating zone more uniform. [0003] Please refer to figure 1 Shown is a schematic structural diagram of a temperature control system in the prior art. Such as figure 1 As shown, the temperature control system includes: a heater, the heater includes three heating units, respectively a first heating unit 41, a second heating unit...
