Cloud-Based Smart City Solutions

KALKI.IO IoT solutions for Smart Cities provide comprehensive advanced metering and B2B billing solution to smart city developers or bulk consumers. KALKI.IO cloud and the edge-based platform supports open standard protocols such as DLMS/COSEM, MQTT gateway, Mbus, Modbus, and various meter-specific protocol adaptors to communicate with energy meters, water meters, gas meters, and BTU meters. The billing is implemented based on the master utilities concession agreement and integration of metering data directly from meters in the field or from the SCADA server, network service provider servers for ICT data, and billing. This IoT solution for smart cities will also provide an interface to exchange collected meter data to any third-party CRM system of the client. It is a very secure platform that can be deployed on-premise or on a cloud. Software built on cloud-based technologies can be leveraged to connect and manage millions of devices such as meters, EV charging controllers, Solar inverters, distribution automation assets, and other sensors and devices that may get deployed during the expansion of the smart city.

Smart City Metering Head End

Smart city metering head-end plays a significant role in the IoT in the energy sector. The metering head-end helps to integrate the meter data management system into utility applications. Besides the network gateways are also commanded by the smart city metering head end, which helps to forestall the overload into the network. Most of the utility companies use a two-way communication system that is between smart meters and headend systems. Smart city metering head-end equips data transmissions and reception, also directs the operations of smart meters, further helping to store load data in a regular interval which supports B2B customer billing. Our smart city metering head-end system is feature-rich and compatible with various energy meters.

Major Advantages

Kalkitech’s “bottom-up” solution approach is an Integrated meter data acquisition, meter data management, and billing system. The advantage of this approach is the tight integration of data because of which the invoices are more accurate and consistent. Easy and Accurate reconciliation of bills means faster receipt of payment.

Future flexibility to include Business to Customer meter billing system, by integrating with the utility system. The advantage of cloud-based utility billing software is a quick reconciliation of bills as the data collection and processing platform is the same.
