为了提高速度和效率，在上一代电网分析仪的基础上采用DSP和AVR单片机构成双CPU处理器平台的电网分析仪系统，其中DSP计算参数，AVR单片机控制报警，充分利用DSP处理大容量数据和复杂算法的能力，以及AVR单片机接口的控制能力。DSP与单片机之间通过SPI接口通信交换信息。研究结果表明该系统设计性能要优于上一代电网分析仪。
- Abstract:
- In order to improve the speed and efficiency of the electrical power network analyzer,a dual CPU processor based on the last production is designed in this paper,which consists of DSP and AVR singlechip microcomputer.DSP calculates the parameter of electrical network and AVR single-chip microcomputer manages the control and alarm function.The electrical power network analyzer makes full use of dealing with a lot of data and complex arithmetic of DSP,and the interface control of AVR single-chip microcomputer.DSP communicates with single-chip microcomputer through SPI interface.The research results show the electrical power network analyzer is better than last production.
