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,采取菜市供电电源、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.

Abstract:

In order to realize the online monitoring of the working state of the rail switch machine, a new power sensor device is designed. The device is based on the high-speed, assembly line structure MCU system, combined with the high-precision three-phase power special chip ATT7022 with DSP core, which constitutes the core part of the device. Considering the harsh working environment and large interference of the system, the necessary anti-interference design is carried out by the vegetable market power supply, signal acquisition channel and signal output channel, which realizes the characteristics of high precision, low power consumption and strong anti-interference ability.
