摘　　要：研究设计了一种新在线监测煤尘的装置,以单片机系统作为主控制器,采用煤尘样本采集模块和煤尘图像传感模块等部件作为探测器。在图像采集控制单片机的协调下由探测器获取煤尘显微图像并压缩,通过光缆将压缩后的图像传输到地面监控中心,由服务器解压缩后显示煤尘图像并给出煤尘粒径分布、长短径比、圆度等检测结果。本设计采用了实时抽气取样并显微观测的新方法,改进了传统煤尘测量定时定点的缺陷,实现实时采集煤尘样本、显示煤尘显微图像、监测煤尘粒径分布。An instrument for on-line coal dust measurement are developed, it regards SCM system as the main controller, coal dust collector （CDC） and coal dust micro-image sensor （CDMIS） as detector. Under the control of SCM, coal dust particles micro-images are got and compressed by CDC and CDMIS, these images are transmitted to ground control center through optical cable, coal dust micro-images are decompressed, and detection results which include coal dust particle size, aspect ratio and circularity distribution are showed in the server of ground control center. This design adopt new technology of getting coal dust sample and micro-images on line, it improve the defect of getting coal dust samples only at one point or at one place of conventional common monitoring device, so this instrument can get coal dust sample, display coal dust micro-image, monitor particle size distribution.
