摘　　要：介绍了一种基于OMAPL138嵌入式处理器的球磨机负荷检测系统设计方案。根据实际需求和当前球磨机负荷检测方法,提出对应的系统硬件及软件设计方案。该方案利用OMAPL138内部两个处理器内核在架构上的非对称性,更为高效地实现了系统的人机交互功能和数字信号处理。通过对球磨机产生的磨音信号进行频域分析,判断球磨机的负荷状态,为球磨机控制策略的调整提供相关参考依据。该系统可以应用于水泥制造、金属选矿等使用球磨机的行业。A design scheme of mill load measurement system based on OMAPL138 processor is proposed. The hardware and software design scheme of corresponding system is proposed according to the current mill load measurement method. The scheme utilizes the non-symmetry of two internal processor cores to efficiently implement human-computer interaction and digital signal processing. The mill load status is determined through the analysis of frequency domain characteristic for the mill sound signal,providing relevant reference basis for the control strategy adjustment of mill. The system can be applied to the sites with cement and metal processing using mill.
