These power informations of power, frequency, power factor also calculate available electricity consumption by the accumulation to power in a period of time and set
Standby accumulative electricity consumption information during this period of time.
8. monitoring device according to claim 7, which is characterized in that the signal operation processing circuit includes A/D conversion
Device, dsp chip, Shared Memory chip, cpu chip, the A/D converter convert analog signals into digital signal, so
Voltage, electric current and the phase digital signal after conversion are sent into DSP afterwards and carry out signal processing；DSP signal processing is to feeding
Digital signal carry out CIC filtering, HPE high-pass filtering, | x |2Signal absolute value product, LPE low-pass filtering and Integral Processing,
By treated, signal is put into Shared Memory chip, reads the parameters of electric power needed that performs mathematical calculations by CPU
Data.
9. monitoring device according to claim 8, which is characterized in that the power param eter supervision module further includes storage
Device, voltage that the signal operation processing circuit is calculated, electric current, power, accumulative electricity consumption, frequency, power factor these
Power information storage is in memory, or module is sent to wireless data receiving device and is counted by wireless communication for selection
According to Real time dynamic display.
