摘　　要：为了实现对铁轨转辙机工作状态的在线监测,设计了新型的功率传感器装置.该装置基于高速、流水线结构的MCU系统,结合自带DSP内核的高精度三相电能专用芯片ATT7022,构成装置的核心部分.考虑到系统工作环境恶劣,受到干扰大的特点,采取对供电电源、信号采集通道以及信号输出通道进行必要的抗干扰设计,实现了高精度、低功耗、抗干扰能力强的特性.To realize the on-line detection of woking conditions of the Rail Switch Machine,this paper designs a new Power Sensor,which is based on a high-speed and pipeline structured MCU system,combined with the high precision special chip ATT7022 which owns DSP kernel for three phase electric energy,foming the core of the whole device. Taking the had working environment and large inference of the system into consideration,we carry out necessary anti-jamming design to power supply, signal collection and output channel, to achieve the characteristics of high-precision ,low-consumption and strongly anti-jamming
