Solution
Newest LoRaWAN Solution V1.2.pdf
Introduction for LoRaWAN Communication mode:
LoRaWAN communication mode for meter reading and parameter setting.
When reading the meter, you can use the meter data remote
transmission software provided by our company to read the meter and
set the parameters. According to the power industry standard DL / T
645-2007 (supporting part of the communication protocol), software
and hardware systems that fully meet the protocol requirements can
be designed for meter reading and parameter setting.
LoRaWAN is a set of communication protocols and system
architectures designed for LoRa long-distance communication
networks.
LoRaWAN Gateway is a super-penetrating, easy-to-deploy IoT gateway
that is specifically designed for environments with complex
buildings and strong network penetration requirements, such as
parks and large buildings.

The function of data-transfer:
The meter can transfer data automatically on the reading date( 1st
to 27th are programmable ).That is the transfer of total forward/
reverse active energy.The meter can store the data in the previous
12 months and store the data for 10 years at power failing.
Recording reverse energy:
The meter can record the total time of reverse energy and the last
time period of reverse energy.
Meter programming. The meter can restore the times of programming
and the latest programming time.
Remote control function:
The meter has the function of remote control through RS-485, PLC,
LoRa and etc.
