Multi-modal Sensor Measurement System for AMI Intelligent Operation and Monitoring

To achieve the “double carbon” goal and realize intensive development and intelligent management of Multimodal equipment, the advanced metering infrastructure provide the key role of for the development of the smart grid. The head end system of advanced metering infrastructure provides two-way communication between smart meters and data processing center system, and as the management center of smart meter deployment, which realizes data collection, data transmission, data processing and data application of all smart meters, concentrators and other devices through HES construction. Business monitoring is also included, along with a process portal for end users. The communication management architecture of HES system is built based on the communication technology framework of high concurrent processing, multi-connection mode and high-capacity collection, ensuring the access and communication connection management of meters with different communication modes such as million-level dualmode, NB-IoT and 4G, etc. It is compatible with the mixed working mode of long and short connection mode, client and server side, ensuring the timeliness and integrity of data.
