Abstract

An energy-saving temperature controller applied to a thermostat comprises a power circuit, a temperature sensing circuit, an analog-digital conversion circuit, a microcomputer computational circuit, a parameter setting circuit, a power amplification and output circuit and a display circuit, wherein the power circuit generates +5V and -5V voltage so as to supply power to the whole equipment, the temperature sensing circuit acquires temperature signals of a heating element through a thermocouple, the temperature signals are transmitted to the microcomputer computational circuit after being subjected to amplification and analog-digital conversion to serve as processing reference signals of the microcomputer operational circuit, the parameter setting circuit is used for setting parameters for the microcomputer computational circuit to operate, the microcomputer computational circuit operates according to the set parameters and the processing reference signals so as to obtain a computational result, and the computational result is transmitted to the display circuit for displaying. Meanwhile, the microcomputer computational circuit sends a control command to the power amplification and output circuit according to the computational result, and the power amplification and output circuit executes heating output and cooling output or not performs output according to the control command.

Description

[0001] technical field [0002] The invention relates to the field of constant temperature control, in particular to an energy-saving temperature controller applied to a constant temperature device. Background technique [0003] In related epitaxy (MOCVD) equipment used in the production of plastic materials, the raw materials should be kept in a device with a relatively constant temperature, and temperature fluctuations will affect various parameters of the produced materials, thus deviating from the expected experimental purpose. Such as image 3 As shown in , the raw material production of general MOCVD equipment includes a proportional-integral-derivative (PID) temperature controller and a constant temperature bath. A temperature sensor, a heater, a refrigerator and a stirrer are installed in the constant temperature bath, and its The temperature control mode is: make the heating and cooler in the state of being on and off for a while, and use the PID algorithm to contro...
