＃ Passed the
inspection of China's Electric Power Science Research Institute,
registration number is CGZ086-2j
＃ Use of Ethernet
LAN/ Internet for Remote Meter Reading and Data Management
＃ Support all functions (data reading,
time-triggered operation and management) of the Archnet AMR system.jpg)
＃ Able to transmit data to higher level
hosts station through PTSN and GSM network (or any other RS-232
standard communication facilities and channels)
＃ Standard RS-232 interface which
facilitates site debugging and data checking
＃ Communicate with lower level Meter
Interface Unit (MIU) and Multi-channel Meter Interface Unit (MMIU)
using power line
＃ Able to issue broadcast commands
simultaneously through all 3 phases of R, Y and B.
＃ All commands have clock-adjusting
function
＃ Absolute industrial grade PC and modem
warrant against failure under harsh operating conditions
＃ Large capacity solid-state disk to store
all types of data. This will help to reduce the frequency of
connections to host station and increase the efficiency of each
connection. This is especially imperative in practical application
where an extensive automatic metering network is deployed. The
host station may not be able to communicate frequently with every
Data Concentrator Unit (DCU) . This requires each DCU to store
large amount of data to reduce the load of the host station.
＃ Three-phase power supply ensures the
system to operate well even when any 2 phases are cut off
＃ Check the voltage levels of 3 phases
automatically. The time and duration of all blackouts and
disruptions of any phases is logged. It is able to perform
self-diagnosis and monitor the working conditions of MIU and MMIU
. It is able to record and report any abnormalities to the higher
level host station
＃ Alternative of metallic and plastic
casing, both of which can be lead-fused. Fire resistance and
electric insulation of the casing measure up the national
standards
