Description

technical field [0001] The invention relates to the technical field of energetic material evaluation, in particular to an automatic monitoring system and monitoring method for quality changes of energetic materials. Background technique [0002] Energetic materials are substances that perform work through violent chemical reactions, and are widely used in many fields such as weapon systems, aerospace, and mineral mining. However, energetic material itself is a relatively unstable substance, which will undergo slow thermal decomposition during production, storage, transportation and other processes. The occurrence of such thermal decomposition brings stability problems to energetic materials. If the energy-containing material is stored in a large amount and stored for a long time, the accelerated reaction of heat accumulation due to the heat released by the thermal decomposition of the energetic material is not easy to dissipate, or the accelerated reaction of self-catalysis...
