Embodiment 1

[0044] The flow chart of the temperature control method of the microwave oven disclosed in Embodiment 1 of the present invention is as follows: figure 1 shown, including:

[0045] Step S11: collecting the temperature in the microwave heating furnace in sections.

[0046] In the process of executing step S11, it is based on the thermocouples placed in each segment in the segmented space in the microwave heating furnace. Each thermocouple is used to collect the temperature in the furnace of the section where it is located. When the temperature of the section is required by the controller, the thermocouple corresponding to the section will collect the temperature of the corresponding section.

[0047] Step S12: Comparing the deviation between the temperature in the furnace and the set temperature through the PID command, obtaining the deviation amount, performing PID calculation and processing on the deviation value, and obtaining the corresponding control amount.

Abstract

The invention discloses a temperature control method and a system of a microwave oven, and the microwave oven. The method comprises the following steps of: collecting a microwave oven temperature in stages; comparing an oven temperature and a set temperature through a (Proportion Integration Differentiation) PID instruction, obtaining a deviation value, carrying out the PID calculation and processing on the deviation value to obtain a corresponding controlled quantity; regulating a power of a microwave source based on the controlled quantity; and controlling a temperature of the microwave oven based on the regulated power output by the microwave source. Temperature control accuracy of the microwave oven is increased, thus, problems of high-cost implementation manner of a PID control method, complicated operation steps, heavy-workload microwave oven and a large quantity of manpower and financial resources wasting in the prior art are solved.

Description

technical field [0001] The invention relates to the field of microwave heating furnace control, and more specifically, relates to a temperature control method and system for a microwave heating furnace and a microwave heating furnace. Background technique [0002] With the development of my country's industrial technology, microwave heating furnace, as a kind of equipment made of refractory materials for calcining materials or firing products, is more and more widely used in industrial fields such as machinery, metallurgy, petroleum and gas. [0003] Most of the internal temperature control of the microwave heating furnace adopts the PID control method, and there are mainly two ways to realize the PID control method. One is to use the PID process control module. Users only need to set some parameters when using this module, which is very convenient to use. One module can control several or even dozens of closed-loop circuits. But this kind of module is expensive and is gene...
