Problems solved by technology

Among them, the measurement accuracy of thermal resistance is high, but the response time of thermal resistance is generally longer than that of thermocouple, which cannot meet the requirements in occasions with real-time requirements; at the same time, the existing multi-channel temperature signal acquisition method cannot guarantee the consistency of each signal Therefore, the obtained temperature distribution is not accurate enough; at the same time, the upper computer can only monitor the temperature of the sampling point, and cannot fully reflect the temperature distribution inside the pipe wall in real time, which has certain limitations

Abstract

The invention relates to a method for real-time monitoring of dynamic temperature distribution inside a pipe wall, comprising: collecting the temperature of each monitoring point; calculating the experimental temperature variation function between the monitoring points; selecting a spherical variogram model, and fitting the experimental variogram , to obtain the theoretical variogram; the sampling plane is divided into grids, and the center point of each grid is the prediction point; the theoretical variogram value between the monitoring points in the neighborhood of the prediction point and the distance between each monitoring point and the prediction point are calculated. Theoretical variogram value; solve the Kriging equations to get the Kriging weighting coefficient; calculate the Kriging interpolation temperature of the predicted point; get the temperature distribution cloud map of the sampling plane. The invention can realize the acquisition of temperature distribution inside the pipe wall with simple structure and high precision at relatively low cost.

Description

technical field [0001] The invention relates to a method for real-time monitoring of dynamic temperature distribution inside a pipe wall. The invention can be applied to the field of temperature distribution measurement inside the pipeline wall. Background technique [0002] Temperature is one of the most important process parameters, monitoring the dynamic distribution of pipe surface and internal temperature will help to gain insight into the heat transfer and other characteristics of the pipe. At present, the existing research on the temperature distribution of the pipeline surface mainly uses the infrared principle to realize the measurement of the pipeline surface temperature. The real-time performance is good and the technology is relatively mature. For the temperature distribution inside the pipe wall, the method of implanting temperature sensors is mostly used at present. This method has low cost and has a wide range of applications, but there are also some problems...
