How to recharge by AMI System?
This AMI system can communicate with smart meters via DCU.
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.
This excellent 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 transferred correctly or detect where the water pipes are broken.
