Smart Bluetooth Parent-Child Electronic Energy Meter: Single Phase, LoRaWAN / Nb / 4G / WiFi
DDZY2397 single-phase IoT Bluetooth parent-child electric energy meter consists of one parent meter and multiple child meters. It adopts digital signal processing chip, permanent storage of information, standard LoRaWAN,Cat. 1, Bluetooth and RS485 communication interface, LCD and other technologies. The advanced SMT surface mounting process is adopted for the electric energy meter. The shell is made of high-strength, flame retardant and environment-friendly materials, which is novel, beautiful and applicable. It has high insulation strength and corrosion resistance. The meter integrates many functions, including electric energy metering, information storage and processing, information interaction, etc.
Our Advantages
The single-phase IoT Bluetooth child meters and parent meter exchange data wirelessly via Bluetooth. The transmitted data contains relevant information for the corresponding receiving meters, which are processed after comparing the information. This solution is suitable for situations where energy meters are installed densely, eliminating the need for RS485 wiring and making the overall deployment more convenient and cost-effective.
Example: the platform issues instructions that are sent to the corresponding parent meter through the communication interface of LoRaWAN/NB-IoT/Cat.1/WiFi (optional). The parent meter then transmits the instructions to the child meters via Bluetooth. Upon receiving the data, the child meters within multiple ranges will perform corresponding operations based on the child meter information in the data. When the child meters upload data through Bluetooth, the data also contains the entered parent meter information, and the corresponding parent meter sends back the data to the platform after receiving it.
1.Communication modes: Built-in Bluetooth/LoRaWAN/NB-IoT/Cat.1/WiFi
communication modules and SIM cards, suitable for 4G/5G operator
networks.
2.Electric energy metering: the function of measuring positive active
and negative active electric energy. It can measure, store and
display the voltage, current, power, power factor, frequency and
other operating parameters and status of the current watt hour
meter.
3.Remote on-off: send power off command through
Bluetooth/LoRaWAN/NB-IoT/Cat.1/WiFi communication modes to cut off
the user's load circuit. Or send the power transmission command to
connect the user load circuit.
4.Data communication: active upload/two-way transparent transmission
function. Actively transmit data to the corresponding platform
through Bluetooth/LoRaWAN/NB-IoT/Cat.1/WiFi (optional) wireless
network. The default interval is 4 hours (settable).
5.Power Limitation: optional maximum power limitation and intelligent
anti-theft electricity. It has overload protection function.

Display Description
LCD full-screen display schematic diagram (as shown above)
The specific display items are listed as follows:
Status indicator lamp:
The electricity meter uses a bright, long-life LED as a pulse
indicator light.
It has active power pulse indicator light: red, usually go out,
flashing when measuring active power.
LoRaWAN/Bluetooth/RS485/Cat.1 Module status indicator: green. Always on indicates online,
and flashing indicates going online.
LoRaWAN Smart Electric Meter: The Future of Electric Management
LoRaWAN (Long Range Wide Area Network) Smart Electric Meters bring
several key features to the table, largely due to the specific
advantages of the LoRaWAN communication technology itself. Here are
some key features:
Long-Range Communication: LoRaWAN has a range of up to 15 kilometers in rural areas, and up
to 5 kilometers in urban areas. This makes it perfect for smart
meters, especially in areas where meters are spread out over large
distances.
Low Power Consumption: LoRaWAN devices consume very little power, which means the smart
meters can operate for years without needing a battery replacement.
This is crucial in remote areas where regular maintenance may be
impractical.
High Capacity: A single LoRaWAN gateway can handle up to thousands of nodes,
meaning that a single gateway can receive data from thousands of
smart electric meters, making it a cost-effective solution for
large scale deployments.
Security: LoRaWAN uses two layers of encryption (unique network,
application, and device keys) to ensure that the data being
transmitted is secure. This is important in smart meters where
privacy and security are key concerns.
Adaptability: LoRaWAN's Adaptive Data Rate (ADR) feature optimizes data rate,
airtime, and energy consumption, making it suitable for varying
network conditions.
Bi-Directional Communication: Unlike some other technologies, LoRaWAN allows for both uplink
(device to server) and downlink (server to device) communications.
This enables not just data collection, but also remote control or
firmware updates if necessary.
Geolocation: LoRaWAN enables geolocation without additional power consumption,
which can be beneficial in certain metering or grid applications.
Interoperability: LoRaWAN is based on open standards, which allows devices from
different manufacturers to work together seamlessly. This is
crucial for utilities companies who might have meters from
different vendors.
Note
INSTALLTION
Live installation of wiring is strictly prohibited!
