智能水表和煤气表设计考虑
Gas and Water AMR (Automated Meter Reading) is an electronic metering (e-meter) technology that includes both the metrology and a one-way communication medium that collects and presents time synchronized interval meter data to utilities and provides usage profiles of customers’ consumption over time. It combines high powered end points, network collectors, a data collection engine and fixed network technology to enable providers to know who is using how much gas and when.
Gas and Water AMI (Advanced Metering Infrastructure), sometimes referred to as smart metering, is a two way communications network that adds additional communication and control capability to AMR that can include valve control and customer access to consumption data.
