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.

Smart Bluetooth Parent-Child Electronic Energy Meter: Single Phase, LoRaWAN / Nb / 4G / WiFi 4

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.

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
