Abstract

The application discloses an on-line intelligent ammeter precision monitoring method and device. On the basis of uncertainty of different channels output in the previous monitoring period as well as total occupied time of each channel in the previous monitoring period, a scheduling table of each set channel in a next monitoring period is obtained; according to a channel allocation mechanism, precision data and uncertainty data of an intelligent electric meter are continuously updated and optimized and thus the online monitoring of the intelligent electric meter precision is optimized, so thatthe online monitoring precision level is improvedand effective support is provided for stable and reliable on-line monitoring of the precision of the intelligent electric meter. The technical problemsthat the monitoring precision improvement based on improvement of single channel injection signal applying time is limited by time and thus the level of the on-line monitoring precision is difficultto improve according to the existing on-line monitoring mode of the precision of the intelligent electric meterare solved.

Description

technical field [0001] The present application relates to the technical field of smart meter quality detection, in particular to a method and device for on-line monitoring of smart meter accuracy. Background technique [0002] With the widespread application of smart meters, the number of on-network operations is increasing day by day. The huge number and complex and changeable operating environment make its operation and maintenance more and more difficult, including daily maintenance management, inventory management and product replacement. As a legal metering device for a new generation of electric energy consumption, smart meters are the only basis for electric energy consumption and payment. Since electric energy is currently the most important form of energy in social production and life, the accuracy of its measurement is related to all aspects of social activities. Therefore, to ensure Controllable and measurable accuracy of online energy meters is particularly impor...
