The rapid development of real-time digital signal processing and ultra-large-scale integrated circuit technology has continuously promoted the improvement of the performance of digital signal processors, making them play an increasingly important role in the fields of signal processing, military and civilian electronic technology, and their application breadth and depth are also constantly expanding and deepening.
The main structure of watt hour meter is composed of voltage coil, current coil, rotary table, rotating shaft, brake magnet, gear, meter, etc. Single phase electricity meters are generally civil equipment connected to 220V.
Smart meters use the design of electronic integrated circuits, so compared with inductive meters, smart meters have great advantages in terms of performance and operational functions.
The rapid development of the real-time digital signal treatment and super large scale integration(SLSI) technology continuously pushes the improvement of the performance of the digital signal processor, which lets it play a more and more important role in the areas, such as the signal treatment, the military and civil electrics technology, etc., and its application width and depth also continuously enlarges and deepens.
Prepaid electricity meters usually display the degree rather than the amount. Prepaid electricity meters usually display electricity consumption in degrees. For example, if the meter displays 866, then the current electricity consumption is 86.6 kWh. In addition, some smart prepaid meters may display the amount of money, but this is not a common situation.
Single phase electronic energy meters have many characteristics, such as accurate measurement of forward and reverse electrical energy, stable performance, infrared and RS485 communication interfaces, convenient data exchange, and time-sharing measurement functions.
