AI Technical Summary

Technical Problem

The temperature monitoring efficiency of open-pit coal yards is low and affected by human factors, so it is difficult to detect spontaneous combustion risks in a timely manner. The existing manual detection methods are inefficient and have limited scope.

Method used

The coal field temperature measurement system based on infrared scanning is used to construct a temperature diffusion model and perturbation sub-model of coal pile category, dynamically adjust the diagnostic strategy, and combine it with the inspection unit to perform real-time data correction and abnormal warning.

Benefits of technology

The early warning efficiency and temperature monitoring accuracy of abnormal temperature areas in the coal yard are improved, ensuring the safe operation of the coal yard, and avoiding the lack of timely warning of potential risks caused by the limitations of infrared data.

Abstract

The invention relates to the technical field of coal yard temperature measurement, in particular to a coal yard temperature measurement system based on infrared scanning. Comprising a central control unit used for setting a plurality of coal pile sub-areas according to coal yard parameters; the measuring unit is used for acquiring infrared data of each coal pile sub-region and generating an infrared data packet of each coal pile sub-region; the monitoring unit comprises a plurality of monitoring sub-modules, and the monitoring sub-modules are used for collecting monitoring data of each coal pile sub-region and generating a monitoring data packet of each coal pile sub-region; a plurality of coal pile categories are constructed based on historical coal pile parameters of a coal yard, and a temperature diffusion model of each coal pile category is constructed based on characteristic parameters of each coal pile category, so that a diagnosis strategy of each coal pile category is dynamically adjusted, and the recognition and early warning efficiency of an abnormal temperature region in the coal yard is improved. The situation that potential risks cannot be early warned in time due to limitation of infrared data is avoided, and safe operation of the coal yard is guaranteed.
