Popis: | 97 With the development of the high performance chip DSP (Digital Signal Processor), application of digital controlling techniques to power control is becoming a trend. This article demonstrates that power signal processed by dsPIC can perform calculation of electricity consumption, data sorting and preservation and thus replaces the traditional mechanical power meter which displays only reading of power. Besides, this new power meter can automatically upload the electricity consumption to the Internet, while the traditional one depends on handwritten record. In this way, the new power meter serves well for the general public whether they are at home or not. On the other hand, the charging rate varies in different periods of time. This new meter is also a prepayment meter; the prepayment card serves to identify each meter as well as keeps it from being misappropriated. |
