电气信号 meaning in Chinese
electric signal
Examples
- Electric signalling systems for railways
铁路用电气信号装置 - Fixed railway equipment . drawings and diagrams for electrical signalling installings . graphic symbols
铁路固定设备.电气信号装置图形和制图.图形符号 - The electric point machine is an important one of railway electrical signal devices . generally , it is used to throw the point and indicate the point ' s position
电动转辙机是铁路系统中一种重要的电气信号设备，它的主要作用是改变铁路道岔的开通方向，并反映道岔的状态位置。 - It first classifies power quality disturbancesinto stable one and transient one by wavelet ’ s multi - resolution analysis , and thencompresses the stable and transient disturbance signals by fourier transform andorthogonal wavelet packet transform , respectively
在此基础上,提出一种针对复杂电气信号的基于傅立叶变换和小波包变换的综合电能质量扰动信号数据压缩新方法。 - The signal sampling circuit fulfill the tasks of sampling signal and changing the double polarities signal to the single polarity signal ; the drive circuit receives the pwm signals from dsp and pass the signals to ipm through optical - couple devices ; the protective circuit safeguard the system against high current , high voltage , low voltage and high temperature on the ipm model
其中信号处理电路主要完成采集输出电流和中间直流环节电压信号，并对采集到的电流信号进行极性变换处理的功能；驱动电路接收dsp输出的高频驱动信号，通过耦合器件直接驱动ipm模块；保护电路利用采集到电气信号对整个系统实施保护，包括过电流、过电压、欠电压、 ipm模块过热等。
