摘　　要：为了解决煤矿井下因环境恶劣导致通风电机保护系统控制功能下降的问题,提出了一种基于ARM的通风电机保护系统优化。该优化是从软硬件着手的,硬件采用ARM LPC2919为微处理及智能逆变器IPM PS21865为功率输出器,优化了系统结构,并实施速度和转矩的双闭环监控,增强了系统稳定性。软件采用数字滤波器算法优化温度信号,并以FFT与数据融合相互结合算法建立了电流的动态跟踪模型,以此替代传统控制模型中的经验公式。实验结果验证了所用方法的正确性和有效性。Due to the harsh environment in coal mine, the function of protection system for ventilating motor declines. To address the problem, the l optimization of protection system for ventilating motor based on ARM is proposed. The optimization system includes two parts of hardware and software. The hardware adopted ARM LPC2919 as microprocessor chip and IPM [Intelligent Power Module] PS21865 as inverter, which optimized system structure. The double closed-loop feedback on speed and torque strengthened system stability. The software used digital filter to optimize temperature signal and the dynamic tracking model of current signal was established with FFT （Fast Fourier Transform ）and data fusion algorithm. The way replaced the？traditionally empirical formula. The experimental results verify that the methods are correct and effective.
