The first part of this design first introduces the research background and present condition about electricity monitor of solar power system. Secondly, it points out the main work of this paper. The second part of the paper puts forward a new kind of low-energy consumption, low cost design method of electrical quantity monitor. Basing on a detailed analysis of the A/D conversion module, I/V, V/V conversion module, power supply module, output module, it gives the overall scheme of the system hardware design and particularly analyses the innovation of this system design in detail---realizing I/V conversion by Hall current sensor almost without the consumption of energy. The third part carries on the design and program of the system software and simulates A/D convertor and LCD monitor by Proteus. The forth part actually produces the electricity monitor of small solar power system, tests and analyses the precision of the system. The result shows that the electrical quantity monitor is low-power consumption and with the test time going, its accuracy will gradually improve. Finally, the study subject is summarized, and a new direction is pointed out. Keywords: solar power system, AT89S52, power monitor, Hall sensor 目录 摘 要 I Abstract II 目录 III 第一章 绪
