Abstract
An electric energy metering and measuring system comprises a metering management system, a plurality of metering management units and a plurality of metering terminals. The metering management system reads measurement data in the metering management units regularly in a polling manner, displays real-time data, and saves history data regularly to facilitate further inquiry and analysis; control modules of the metering management units control interface modules to perform information interaction with the metering management system and the metering terminals, and control a display module to display various parameters after the measurement; and sampling modules in the metering terminals collect current and voltage sampled signals in all measurement points in real time, the current and voltage sampled signals are filtered by a signal filtering module, and digital signals are obtained through an AD sampling module, then a data processing module treats the collected digital signals and transmits remote measurement to the metering management unit through a bus. By adopting the system, electric energy can be measured accurately in real time.
