Single Phase LoRaWAN Smart Electric Meter with Remote Meter Reading Function
Product Overview:
DDS155 series BR (LoRaWAN) single phase electric meter is a kind of fully digitized energy meter which adopts the SOC high-density V9821S chip. Besides measure active energy, it also has function for online power display, smart anti-tamper, overload control, remote meter reading and etc. It sends data to corresponding gateway through LoRaWAN wireless network. It has advantages in high accuracy, low power consumption, and good stability that can be widely used for the single phase alternating current in city, rural areas or factory enterprises, etc.

Composition theory:
The voltage/current sampling circuit samples the voltage of the power grid and the current flowing through the electric meter, sampled voltage and current signals are multiplied to obtain a power value, and then integrated according to time to obtain electric energy. Smart energy meter measure the energy through output CF pulse counting, after electric meter corrects the error, only the CF pulse is counted to obtain the electric energy which is saved by the storage. The microprocessor simultaneously performs the functions of displaying and exchanging information with external device. Its principle block diagram is shown in Figure 1.
Operation, debug and installation
1) No need for extra operation and debug after leaving factory, can be in normal use since finished installation by professional person.
2)Before installation, please check manufacture’s seal is in good condition.
3)Meter should be installed indoor or on the fire-proof wall outdoor, the height is about 1.8m, no corrosive gas in the air.
4)Meter should follow the connection diagram, using copper wire or copper terminal clamp for input.
5)Main terminal connection
6) Main and auxiliary terminal connection
Main terminal connection follows Figure 2, 1 as L In, 2 as L Out, 3 as N In, 4 as N Out. There are 4 auxiliary terminals on the top of main terminal, in which 7 & 8 as measure pulse output.v
LoRaWAN communication interface:
Using LoRaWAN communication for meter reading and parameter setting. When meter reading, remote meter data transmission software provided by our company can be used for meter reading and parameter setting. It is also possible to design a software and hardware system that fully complies with the protocol requirements for meter reading and parameter setting according to the power industry standard DL/T 645-2007 (supporting part of the communication protocol).
