摘要
介绍了一种基于32位ARM内核微处理器S3C2440和WinCE,配合各种外围器件,采用快速傅立叶变换FFT和小波变换算法及VC++编写的EED上位机软件构成的电梯能效检测系统,实现对电梯的电压电流、功率及谐波的检测。采用主从机模式,通过从机加速度检测模块实时检测电梯运行状态,综合分析电梯耗能随电梯运行状态的变化。通过人机交互媒介可以选择不同评价标准,给出电梯能效标识。
An efficiency detecting system based on S3C2440 and WinCE with some other kinds of devices ,using FFT and Wavelet Transformhas, having a software named EED written in VC ＋ ＋ is introduced.It implements the detection of the voltage 、current、power and harmonic of elevator. Using master-slave machine model, real-time detecting elevator status through the acceleration test module. comprehensive analysising the elevator energy with elevator status changes. Through the man-machine interactive media choosing different evaluation standard, giving elevator energy efficiency label.
