中文摘要:
可燃粉尘浓度到达浓度极限是发生粉尘爆炸的必要条件之一，监测粉尘浓度是预防灾难发生的有效手段，但是目前尚无可燃粉尘浓度实时探测实用技术.为解决这一问题，提出"超声-电场"复合检测方案，完成混合式系统设计；分析复合探测系统数据关系特征，提出两级数据融合模型；对基于最优加权法的数据融合算法开展研究，最终形成可燃粉尘浓度快速探测模型.试验结果表明，采用文中所述"声电"复合浓度探测方法能够实现可燃粉尘的快速精准测量.
English Summary:
The concentration limit of combustible dust is one of the sufficient conditions for dust explosion. The monitoring of dust concentration is an effective method to prevent disaster, but there is no practical technology to detect the concentration of combustible dust up to now. To solve this problem, an ultrasound-electricity comprehensive measurement scheme is presented, and the mixed structure system is designed. The relation of comprehensive measurement data is analyzed and a two-level data fusion model is proposed. The data fusion algorithm based on the optimal weighting method is studied, and ultimately a rapid fuel concentration detection model is given. The results show that the multi-mode fuel concentration detection method is able to realize the rapid and accurate concentration detection.
