Scenario Preset
(1)There are 10 Areas with 1-phase Power System needed to be monitored. (2)Each area has 20 monitoring circuits 1-phase needed to be monitored online. (2)Rated voltage of monitoring circuit is 230Vac L-N, rated current of monitoring circuit is 80A AC. (3)All 1-phase energy meter will be of partial centralized installation in each area, which make it possbile for 1 AWT100-4GHW 4G IoT gateway to support 20 ADL200/C 1-phase Energy Meters using RS485 wired communication in a close range. (1 AWT100-4GHW can support max 25 ADL200/ C energy meters if distance allowed (within 400m) and all 25 Energy Meters were of centralized installation along with this 1 AWT100-4GHW)Devices Deployment Plan
Communication Structure&Logic
(1)4G Communication could be served as one of the final data upstream methods by sending the data to cloud server deployed in Internet so that Acrel IoT System could be interact with these data collected by bottom metering devices like Energy Meter (2)AWT100-4GHW gateway support upstream of 4G communication with MQTT and MODBUS- protocol and downstream of RS485 communication based on MODBUS-RTU protocol. ADL200/C support upstream communication of RS485 communication based on MODBUS-RTU protocol. (3)Based on the communication described in item (2), Acrel AWT100-4GHW gateway could receive the data from ADL200/C energy meter using RS485 communication while sending the data further to cloud server using 4G upstream communication. Thus accomplish a complete communication from bottom metering devices to top system software.
