Smart Meter in Automatic Meter Reading System Single Phase Two Wires DLMS/COSEM
DDZY150 single phase local fee control smart meter is a intelligent electricity metering product, which suit for measuring 220V/50Hz single phase active AC power. It has independent optical and RS485 interface, and also with standard interface of carrier communication module, which can work with carrier communication module from different suppliers. It can support for fee control function. With advantages of high reliable, high accuracy, long life, wide range and etc, it can widely used in city, country and enterprises where need to measure single phase AC power.
Standard: IEC 62053-21 Electricity metering equipment (a.c.) –Particular requirements –
Measured AC voltage and current have been sampled and transported to professional metering chip, after digital processing, they have been changed to the pulse signal, which in direct proportion to active power, and then sent to microprocessor. Microprocessor would accumulate the pulse signal according to the tariff, then get total power and tariff power and put them in register. At the same time, the microprocessor finishes the function of display and changeover with external messages. Please take attention to the Figure 1
2) Remote Fee Control:
It finished parameter setting and remote purchasing through RS485, carrier and other virtual medium..
3) Measuring and Monitoring
It can measure and monitor operating parameter such as voltage, current (including zero line current), power, power factor and etc. The error would not exceed ±1
4) Event Log
When the following faults or alarm appear, LCD would stop on the certain code and backlight keep on.
9) Pulse Output:
Meter has function for LED pulse and electrical pulse output which comes direct ratio with measuring energy. Optical test output device should comply gb/t17215.211-2006, electricity test output device should comply GB/T15284-2002. It has signal output terminal for clock, and the output frequency is 1Hz
10) Load Switch:
External load switch, there is a group of switch signal for meter output. Volume of switch point is AC 220V/2A. Under normal condition, switch signal for output should keep switch on of load switch, allow for power on; When reach certain condition, switch signal for output should drive operation for external load switch, power off.
