General: JQAMR-Z automatic meter reading system is a host driven,
multi-level network system with strong flexibility and
expandability, consisting of a host computer station. The system
employs GPRS, telephone and low voltage power line carrier wave to
transmit data. The host computer in the meter reading center can
make business management and billing management to the data that is
sent back, as well as make calculation, storage and analysis.
Meanwhile, it can also alarm to the abnormal conditions and monitor
the electric meter by real-time to make sure reasonable and
reliable power supply and power usage. System's working methods: 1)
For the single and three-phase carrier wave electric meters
installed in theresidential area, it can transmit the data to the
concentrator by power line carrierwave 2) For the electric meter
with RS485 interface, it can transmit the data to theconcentrator
by 485 main line 3) For the multi-functional electric meters with
RS485 interface installed in the bigusers and the transformer
substation, it can transmit the data to the concentratorby means of
485 main line. For the multi-functional electric meters with
built-in GPRSmeter reading modules, it can transmit the data to the
meter reading center directlyby mobile communications corporation
network 4) The concentrator can transmit the data to the meter
reading center by GPRS, GSMor phone network Terminal devices and
main functions: 1) Concentrator: can collect, store and pretreat
the data of the electric meters, andalso send the data to the meter
reading center. Meanwhile, it can also return thecontrol commands
sent by the meter reading center to the electric meters to
controlthe electric meters 2) Infrared meter-reading device: can
program to the meter and the concentrator, andcan also read spot
data of the electric meter and the concentrator 3) Electric metera)
Single / three-phase carrier wave electric meter b) Single /
three-phase multi-tariff carrier wave electric meter c) Single /
three-phase multi-tariff IC card carrier wave electric meter d)
Single / three-phase multi-function electric meter e) Three-phase
split phase energy electric meter f) Three-phase net electric meter
Main functions of the system software: 1) Supports data
transmitting channels, including phone (GSM data transmitting),GPRS
and direct connection 2) Monitors meter's status by real time,
freezes meter reading data, reads meter atzero and reads meter by
real time 3) Connects and disconnects operations controlled by
remote relay 4) Loads monitor and abnormal energy alarming 5) Sets
the automatic meter reading period and the system time collate of
theconcentrators 6) Supports the data inquiries, line loss
calculation and abnormal line lossmanagement functions entirely 7)
Provides flexible management functions of the report forms such as
stat., inquire,print and make report forms 8) The system software
supports the archives' management functions entirely 9) The system
software supports many databases such as ACCESS, SQL SERVER 10)
Provides the public database interface to calculate the electricity
charges, obtainthe power management data or/and connect with the
charging system of the bank
