Problems solved by technology

Since the image data storage process is a process of data interaction between the host computer and the local, it is very time-consuming
For the amount of data collected at high frame rates, the existing solutions cannot realize that the host computer can read and display image data in real time, and at the same time complete the data storage of abnormal temperature points; so when using high frame rate images for temperature measurement, If there is an abnormal temperature point, the whole system will appear stuck or report an error due to the long storage time

Abstract

The invention discloses a high-frequency temperature measurement infrared data processing method for a high-speed rail overhead line system, which is mainly characterized in that a thread 1 and a thread 2 are set through a multi-thread mode, and the thread 1 is mainly used for image capture, real-time display and abnormal temperature point judgment, so that real-time display and online observation of high-frequency temperature measurement infrared data of the high-speed rail overhead line system can be realized; and the thread 2 is used for storing image data sets before and after the abnormal temperature point. The invention further provides a high-frequency temperature measurement infrared data processing system for the high-speed rail overhead line system. A multi-thread mode can realize parallel operation, can accelerate the storage speed, and realizes infrared temperature measurement processing in a high frame frequency mode; therefore, the problem that high-frame-frequency image capturing and displaying are affected due to the fact that the local storage speed is low is solved.

Description

technical field [0001] The invention belongs to the field of data processing, and particularly relates to a high-frequency temperature measurement infrared data processing method and system for high-speed railway catenary. Background technique [0002] Catenary plays a very important role in electrified railway. With the development of my country's bullet trains and high-speed rail, it is even more urgent to improve the safety and reliability of the catenary operation. It is an important link to maintain the safety of railway transportation by detecting the temperature of the catenary and knowing the parameter status of the catenary at any time. Infrared thermal imaging camera temperature measurement technology can effectively detect whether there is overheating in the electrical connection. In the infrared thermal imaging detection system, the thermal image is captured by software such as the host computer; the image is subjected to temperature measurement analysis and pre...
