【摘要】 目的为了清楚记录火灾事故过程,便于灾后调查分析及预防火灾。方法对火灾现场的环境条件及其复杂性进行研究,并在此基础上,提出考虑环境适应性和环境防护的火灾黑匣子系统的设计思路,进行初步设计。结果火灾黑匣子的外部防护壳体采用了高强度的合金材料,确保了外壳具有较高的硬度和强度,保证了抗电磁干扰能力。内部是主要由二氧化硅凝聚物和石棉粉组成的多重复合结构,具有较好的抗高温火烧性能。结论该设计下的黑匣子实现了对日常使用和恶劣火场环境下的火灾数据的记录、存储与再现的问题。更多还原

【Abstract】 Objective To clearly record fire processes to facilitate investigation analysis and prevent fire disaster.Methods Based on the studies of the environmental conditions and the complexity of fire scene, a design idea of taking environmental adaptability and environmental protection into account was proposed and a preliminary design was made.Results A high-strengthened alloy material was adopted for the external protective shell of the fire black box to ensure that the shell had high hardness and strength and the ability of anti-electromagnetic interference. The internal structure was the multiple composite structure mainly composed of silica aggregates and asbestos powder,with good performance of anti-burning at high temperatures. Conclusion The fire black box can record, store and reappear the fire data in daily use and harsh fire environment.更多还原
