摘要
根据电能计量的实际需要,分析了采用软件实现同步交流采样的工作原理。结合DSP技术给出一种基于TMS320LF2407a芯片和MAX125的软件同步采样处理系统的硬件实现方案及软件设计思想,可减少硬件的复杂度的同时保证检测精度。最后,讨论了系统抗干扰设计。
According to the practical requirements of electric power measurement, the principle of software synchronous sampling technologies is analyzed. The hardware implementation scheme and software design idea are proposed, which are based on the digital signal processor TMS320LF2407a and MAX125. Applying this technology can lower the complexity of hardware while the measuring accuracy ensured. And the design of the system anti-jamming is also discussed.
