1．AMR Definition: AMR (Automatic Meter Reading System) is the remote collection of consumption data from customers' utility meters. AMR use power-line carrier (PLC), PSTN or GPRS or GSM communication technologies. 2．AMRS Automatic Meter Reading System has some excellent advantages such as easy installation and operation way, stable and reliable running. In addition, sustaining continually read the data from meters, remote power on/off and multi-user management system can help to distribute different handling privilege to relational users. 3．Power Meter Single phase carrier wave watt-hour meter with relay is used as the terminal device in AMR system. It can measure active energy consumption with high reliability and stability in power line carrier wave mode. The meter conforms to the requirements specified in IEC ****6 IEC*******1, IEC*******1. Features 2.1 active energy consumption without the calibration during a long operating period 2.2 AMR via power line carrier wave 2.3 using spread spectrum communication technology in the software to implement interconnection between the devices through the power lines 2.4 automatic repeating between PLC terminals 2.5 remote control to power on /off, CONCENTRATOR : Concentrator in AMR system plays many key roles. It acts as collector to gather and store various data from energy meters, terminal units, or any equipment that can conduct PLC communication, as controller to manage the devices, as repeater to bridge the utility central station with the meters or other devices on the power user side. Features To manage at least ***0 metering points To collect and store the data in different tariffs, intervals, and device parameters daily. To communicate with the power user sides through existing power lines effectively. To transfer processed collected and stored data by different types of communication channels to the central station. To activate some intermediate meters as temporary repeater
