摘要
介绍了基于低成本的AVR单片机Atmega64和结合VC++编程的直流稳压电源检定装置的系统结构,详细说明软件设计思路和通信、交流调压电路、纹波测量电路的实现技术,同时对测量结果进行比对。结果表明,该装置测量结果可靠,可以开展校准、检定工作。
A portable verification equipment on the low-cost AVR Atmega64 signal-chip microcomputer and C++ was introduced in this paper, detailedly, the design idea and implementation technology of the programming method, the simulator of communication、circuit of Ac voltage regular、ripple voltage measure. Measurement dates were comparisoned. And the results of thecomparison show that the device can be used to reliably calibrate.
