Most utility companies in the Asia-Pacific extensively use AMR (Automatic Meter Reading) systems based on field-proven products and technologies. Power usage data is measured and stored by advanced solid state remote meters. Data is transmitted through existing cellular telephone networks using analog and digital technologies to achieve system wide coverage at optimal cost. Many companies are now requesting AMR meter solutions that provide two-way cellular data transmission in industrial environments. Cellular technology also enables continuous and reliable data transmission between metering devices and central control.
Moxa's Solution
Moxa's OnCell G3111/G3151 IP modems allow system integrators to deploy an AMR system that transmits data over a GPRS cellular network. As long as the control center is connected to the Internet, it can connect to the remote metering devices, which are constantly collecting data and update the control center at a preset time each day.The OnCell G3111/G3151 IP modems also provide two-way communication that enables system administrators to query the field devices at any time. Using a GPRS network also allows system administrators to avoid high monthly fees and only pay for the basic connection and amount of data
they actually send.
