Description

technical field

[0001] The invention relates to data collection and storage technology, in particular to a real-time collection and storage device for electric energy metering chips. Background technique

[0002] With the development of power electronics technology, electronic energy meters have been widely used because of their multi-functional and intelligent advantages.

[0003] figure 1 Shown is the system structure diagram of the electric energy metering chip. see figure 1 , The energy metering chip is composed of amplifier, analog-to-digital conversion, decimation filter, multiplier and digital-frequency conversion. The current generates differential signals V_I+ and V_I- through the sampling resistor connected to the neutral line, and the voltage generates differential signals V_V+ and V_V- through the voltage dividing resistor connected to the live wire; these differential signals are amplified by the amplifier and converted into digital by analog-to-digital conve...
