摘要
基于ARM的智能化多功能电参量监测仪有较高的性价比和实用意义。在此背景下,提出了一套交流电量数据采集系统的总体设计方案。首先介绍了采用硬件同步采样和过采样技术相结合的测量方法;之后详细介绍了利用基于ARM7核的主控制器LPC2292实现多通道同步交流电量数据采集的硬件电路设计,简要介绍了软件开发思想;最后分析了系统的抗干扰问题,对系统误差进行了分析。实验表明,该系统具有较好的实时性和测量精度。
ARM based intellectualized multi-function electric power monitoring instrument is of high practical value and high performance-to-price radio.In this background,the complete design project of an AC electric power parameter acquisition system was put forward.First,the measurement task by using hardware synchronous sampling and over sampling techniques was introduced.Second,the hardware of multi-channel synchronous AC electric power parameter acquisition system using MCU LPC2292 based on ARM7 were discussed in detail,and thoughts on software development were briefly introduced.Finally,the anti-jamming problems were discussed,and the error of the system was analyzed.The experiments prove that the system can attain good real-time ability and precision.
