LAISON Data Concentrator Unit PCCG-450 (Hereafter referred as DCU) is part of LAISON Advanced Metering Infrastructure (AMI) System.
By adoption of Semtech’s LoRa RF Wireless Module, which features in low power and long communication range, It could realize Remote Meter Data Collection and Valve Open / Close. Also, all the data can be uploaded to Center Management System via Internet or GPRS.
It provides comprehensive, reliable, advanced smart meter solutions to water utilities & authorities, which avoids door-to-door meter checking manually.The Default RF Communication Frequency could be 470MHz / 868MHZ, and communication distance is no less than 5km in line of view.
LAISON DCU could collect meter’s data via RF Wireless Communication, In the meantime, All the data can be uploaded to the Center Management System via Internet for customer monitor or data statistic. Following parameters can be collected now: 1) Battery Voltage 2) Total Consumed Water 3) Total Purchased Water 4) Monthly Consumed Data 3) Meter’s Working Status (Valve Status) 4) Event Record
2)Open / Close Valve Remotely
Meter’s Valve can be remotely opened or closed by sending corresponding command at Center Management System. Open valve or close valve command could be sent to DCU via Internet, and communicate with meter through RF Wireless, to realize bi-directional communication betwen Center Management System and LAISON Smart Prepaid Water Meter.
