Temperature control method based on variable region dynamic temperature acquisition and data fusion

Abstract

The invention relates to the technical field of temperature control, in particular to a temperature control method based on variable region dynamic temperature acquisition and data fusion. The methodcomprises the following steps: S1, reflecting infrared radiation on the surface of an object to a temperature measuring head of an infrared temperature measuring sensor through an infrared reflector capable of rotating at a high speed, enabling the infrared reflector to rotate at a high speed along a set movement path, measuring temperatures of different points on the surface of the object in realtime; and S2, grouping regions according to the minimum unit area, and realizing data fusion according to a method of calculating the average temperature on the unit area through Gaussian distribution. Regional information is added into an algorithm, data fusion is realized according to a method of calculating the average temperature on a unit area through Gaussian distribution, different response speeds are set according to parameters of a regional size self-adaptive regulator and regions with different surface connection sizes, and the power of a laser is regulated, therefore, the temperature of the local area of the surface of the measured object is rapidly, comprehensively and accurately controlled, the temperature control difficulty is reduced, and the temperature control accuracy isimproved.

Description

technical field [0001] The invention relates to the technical field of temperature control, in particular to a temperature control method based on variable region dynamic temperature acquisition and data fusion. Background technique [0002] Temperature is one of the important controlled variables in the process control system. Non-contact temperature measurement methods are usually used in industrial sites, and the detection methods include thermal expansion principle method, pressure temperature principle method, thermal effect method, thermal resistance principle method and heat radiation principle method. Among them, the thermal resistance principle method is one of the most mature methods. Its temperature measurement principle is based on the nature of the resistance value of the conductor or semiconductor changing with temperature, and the change of the resistance value is reflected by the display instrument, so as to achieve the purpose of temperature measurement. . ...
