{Features}
It is a mature AMR system, the total number of measure points into application has increased to more than 1 million  in recent 10 years. Modular design and rack structure design have made  it particularly suitable for centralized mass installation, especially for up-hanging installation. This not  only  can  save  a  lot  of  space  for  installation,  but also make  it much more  against  energy tampering. Automatic meter reading and remote power on/cut off functionality, these both not only  improve  the  efficiency  and  benefit  to  power  utility,  but  also  lower  the  risk  of  the  utility operator who long-time work on site. While shall beneficial to call payment. 
Functions such as illegal case-opening detection, intrusive phrase detection, data encryption are designed,  which  extracted  from  long-time  accumulation  of  customers'  demands  and requirements.  They enables the system successfully solute many pragmatic problems on-site.

{Overview}
★Active energy measure is unitized as single phase Measure Module. They can consist of single phase, dual phase or  tri- phase measurement.  Inside  relay be able  to power connect or disconnect; intrusive phrase detection is available before switching on. 
★There  are  Control Module  and  RF Module was  designed  specially.  Control module read energy data proactively  from measure module  via  internal RS485 bus and  store them  according  to  designated  user  ID  configured.  Energy  dada  can  be  read  from control module  via PLC  channel,  remote power on/off  is  available  according user  ID. The RF module is applied for sending metering results to user display.
★User  display  is  used  for  show  the  meter  reading,  successfully  solved  the contradiction  between  high-hanging  bulk  installation  and  the  consumer's  right  to know. There are PLC or RF channel display selectable. RF display can update its reading within 1 minute for 1kWh increment.
★Concentrator  is  the  center  of  local  communication  network.  It  act  the  commands 
from  power  utility  for  AMR  and  remote  power  connect/disconnect,  and  other 
commands from GPRS channel.
★Each  control module  can manage  up  to  18 measuring modules.  18  single-phase users  or  6  three-phase  users.  It  is  capable  of  illegal  case-open  detecting,  also supporting re-back function.
★Encryption  technology  is  applied  for  system  communication  ,  certification  token used for access control.
