Make full use of the DSP powerful signal processing ability and the modern numerical analysis method. Design the
Watt-hour meter front sampling and measuring module of hardware, as well as a set of accord with national standard GB/T 17883-17883 of 0.2 S
Accuracy of algorithm, at the same time extend the function of harmonic analysis. System overview: three-phase voltage and current
The AD sampling, sampling data via a serial port sent to the processor (DSP), electric parameter meter by DSP of the sampling data
Quantity and harmonic analysis, process the results with a custom LCD display, and through pulse mouth making active and reactive power
Table pulse. DSP adopts BLACKFIN531 of ADI company- a 16-bit fixed-point chip, the highest processing capacity
Up to 800 MIPS, sampling chip AD73360 for 16 bit, supports six channels synchronous conversion, no synchronization error.
Digital, high precision, innovative and extensibility ?
