【摘要】 基于ARM芯片的低压配电在线监测控制器有较高的性价比和实用意义。监控器硬件设计要考虑三相电压电流信号的采集,确保测量精度,与所设计的软件配合可支持数据通信,保存要求记录的各种重要数据,掉电保护等。软件设计要考虑数据采集、键盘处理、数据通信、故障处理、输出控制信号等。还讨论抗干扰滤波设计。提出的算法对脉冲噪声的滤除效果十分明显,具有理论和实际价值。更多还原

【Abstract】 ARM-chip based online monitor for low voltage distribution is of high practical value and high performance-to-price radio. In design of the hardware, it should be considered how to acquire three-phase voltage and current signals, guarantee the measurement precision, support data communication by cooperating with software, record and store significant data. In design of software, data acquisition, keyboard processing, data communication, fault management and output of control signals should be regarded. It also concerns the interference-free filtering design. The proposed filtering algorithm is quite effective for filtering away the impulse noise, and is valuable both theoretically and practically.更多还原
