摘要
针对现有电参数检测仪功能单一、自动化程度不高等缺点,采用ATMEGA162为微控制器、专用电能计量芯片CS5460A为模数转换器,根据嵌入式系统的设计思想设计了三相电参数检测系统.介绍了三相电参数检测仪的硬件结构和软件设计方法,并分析了提高测试精度的方法.测试表明,系统的测量精度可达到0.1级,能满足对设备用电参数监测的要求.
Because of the lack of simple function and low-level automation, the common meter of electrical parameters can not meet the industrial need of automatic measurement in mass production. Based on the design theory of the embedded system, a new kind of measurement system was designed for testing three-phase AC electrical parameters, which uses ATMEGA162 as microcontroller and CS5460A single phase bidirectional power/energy IC of Cirrus Logic as the A/D converter. The design of hardware and software was introduced, and the method to improve the accuracy of measurement was also analyzed. Experiments show that the measuring accuracy can reach 0.1% and the system can meet the requirement of monitoring the electric parameter.
