Software Design And Development Of Infrared Scanning Temperature Measurement System

As the core equipment in many fields such as building materials,chemical industry and metallurgy,rotary kiln's internal working temperature,and kiln wall thickness determine the product quality and production cost to a large extent.In the production process,the surface temperature of the rotary kiln can reflect the internal temperature distribution and the thickness of the kiln wall in real time.Therefore,by monitoring the surface temperature of the kiln in real time,the combustion situation in the kiln can be timely understood,which can prevent the occurrence of red kiln accidents and ensure the product safety and product quality of the kiln.Most of the original software systems have problems such as inaccurate scanning point positioning,low thermal image recognition and low temperature measurement accuracy,and they rely on the PC platform,which cannot realize portable mobile monitoring,and it is difficult to meet the new application needs of users.Therefore,the subject proposes to design and improve the software of the infrared scanning temperature measurement system.The project comes from "Design and implementation of rotary kiln surface temperature monitoring system based on infared radiation development" of the National Natural Science Foundation of China(No.61671049).Based on the original infrared scanning temperature measurement system,this thesis analyses the requirements of the software system,and improves the algorithms.The software system of infrared scanning temperature measurement system includes temperature monitoring software subsystem and streaming media subsystem.The temperature monitoring software subsystem includes data receiving,data analysis,pseudocolor processing,scanning point positioning analysis,data display,data storage,and other modules.The streaming media subsystem includes coding tools,streaming media forwarding server,and terminal player.Because of the shortcomings of the original pseudocolor algorithm,the original pseudo-color algorithm based on rainbow coding was replaced by the pseudo-color algorithm based on equal chromatic aberration,which increases the color band,enriches the pseudo-color display of the image,and is more conducive to human eye resolution.Due to the inaccurate positioning of the original rotary kiln positioning algorithm based on feature point correction,the original positioning algorithm was replaced by the equiangular scanning algorithm,the accuracy of location of scanning points on rotary kiln surface is improved.At the same time,this topic added a streaming media subsystem.The real-time thermal image of the temperature was pushed to the streaming media server by using the coding tool,and the terminal player realized the real-time temperature monitoring by pulling the stream.The temperature monitoring software has been successfully applied in the rotary kiln production site.The results of test indicate that The software displays high image resolution with rich colors,and the average accuracy of positioning is up to 0.2m.At the same time,the function of streaming media allows users to monitor the temperature conveniently.
