Smart Data Concentrate Unit(DCU) For Reading and Controlling Smart meters Remotely Via AMI
ST368 smart data concentrator is dedicated to Smart Metering application and designed as a gateway between metering devices and AMR/AMI system, it creates two ways communication from metering points to AMR/AMRI system, performs task setting, data collection, data transmission and data storage, meter management, GPRS information task execution and RF network management.
ST368 utilize efficiently RS485, RF-LORA media for downlink communication to smart meters and GPRS, 3G, DSL and fiber optic for uplink communication.

Application
This DCU can communicate with AMI system via GPRS modulle in uplink, and communicate with smart meters like electricity meter, water meter and gas meter downlink with RF module.
Take water meter for example: the water meter has RF module built inside, the DCU and get the meter data from RF module, then send to AMI system via GPRS module, then the AMI system can read the meter remotely. When we operate the recharging function, we generate the recharge Token with AMI system, the Token transport to DCU via GPRS module, then the DCU send the Token to water meter. After the credit received by water meter, the remotely recharge successed.
With this DCU, the AMI system not only can monitor the data of single prepaid water meter, but also monitor the prepaid bulk water meter. So we can make sure the data transfered to AMI system is correct and detect where the water pipes are broken.
