Introduction

Analysis of core technical requirements of the standard

Technical indicators	Parameter requirements	Test methods
Infrared detector array	≥320×240	Factory report verification
Spatial resolution	≤1.5mrad	Calculation using the formula α=a/f
Operating temperature range	-20℃~+50℃	GB/T 2423.1/2

Comparative analysis of key technical indicators

The standard divides cotton bale infrared imaging temperature measurement device into cooling type (Z) and non-cooling type (F):

NETD index: The cooling type can reach 50mK, which is better than the 100mK required by the standard
Maintenance cost: The non-cooling type is maintenance-free and more suitable for warehousing scenarios
Response speed: The cooling type takes 5-10 minutes to start, while the non-cooling type can be used immediately

Recommendations for the implementation of the standard

Recommendations for warehouse installation spacing: Based on the maximum detection distance of 40m, one device is arranged for every 1600㎡
Temperature calibration cycle: It is recommended to use a blackbody simulator for calibration every quarter
Alarm threshold setting: It is recommended to set it to ambient temperature + 15℃ (refer to the spontaneous combustion point of cotton)

Background of technological evolution

This standard introduces infrared thermal imaging technology into the cotton storage field for the first time. Compared with traditional point temperature measurement:

Comparison dimension	Infrared imaging technology	Traditional point temperature measurement
Detection efficiency	Whole warehouse scanning	Single point monitoring
Response speed	Millisecond level	Minute level
Positioning accuracy	±0.5m	Unable to locate
