DCU with Distributed HES:
While establishing the number of meters connection with HES, the server will start increasing its capacity. Means scaling up HES to larger extent which eventually leads to Heavy and Bulky system, Costly, and involve Huge maintenance cost these are Problems that faced using HES. Distributed HES is a part of Block chain concept, ie the load of HES distributed among DCU, by bringing the protocols like DLMS, Modbus RTU, Modbus ASCII, IEC62056-21, DLT645 in DCU.
The Intelligence brought to DCU, so that load to cloud will be reduced in distributed HES. Which will keep your HES/ Cloud server at minimal load with minimum scalability and low cost. After Black out, DCU will take care of Data coming from the meter side. Based upon cloud availability data will be pushed by DCU, on an interval basis. So that cloud need not have to be loaded maximum. Works on the basis of Distributed data storage, if DCU stores data from energy meter up to 60 days, the data will be pushed to cloud at the same time.
The data backup will be available in both HES and DCU. So, the data loss rate will be zero. For secure data communication, there is a certification provided between HES and DCU using MQTT with TLS1.2. Provide secure traffic between DCU and HES optimized to minimal in Distributed HES concept.
