Data Collector Advanced Metering Infrastructure for Smart Meter Data Acqusition
The remote reading system adopts the advanced wireless network data transmission technology. It can collect the water, electricity, gas, heat of residents in real-time, and can realize the centralized storage and unified management of data. It conforms the technical requirements of JG/T 162-2009(remote reading system of residents). Compared with the same kind of meter reading system, this system has the features of network self-adaption, free of debug, maintenance-free, stable operation, convenient expansion.
The remote reading system consists of metering management system software, data collector, data concentrator, and smart meter. The concentrator up channel communication type: GPRS network, telephone line network, Ethernet network. And the down channel can match different type of collector according to the actual application. The collector is divided into M-BUS collector, RS485 collector, and wireless connector.
In the remote meter reading system, the concentrator will unify all the meter data and store automatically, at the same time, it can receive the control command from the management center and then transfer to the meter. This system has the excellent compatibility and expansibility. It can manage one kind of smart meter, and also can realize the unified management of water, electricity, gas , and heat smart meter.
1.1 Modular Function Design
The concentrator adopts the embedded module which the R1610C is the core, and has resource like the serial port, Ethernet port, clock, etc.Every function is module designed, and the operation is stable and convenient for expanding.
|Connected Socket No.||Connected Socket Type||The Main Function Description|
|CN2||RJ45||10M/100M Compatible Ethernet Port|
|CN11||SIM LOCK||SIM Card Slot,Install the SIM card when apply the GPRS|
|JP1||2 Chip SIP||Select work mode(work mode or debug mode)|
1.2 Stable and Reliable of Data Storage
The concentrator adopts the memory with 32M large capacity and high reliability. The data storage and check speed is very quick. Support sector balance, long term service life and it will keep the data more than 10 years after power off.
1.3 Fully Automatic Function Design
The concentrator maintains the communication link of subordinate equipment. It can realize the data collecting automatically, without human intervention.
1.4 The concentrator has the function of restart from failure and power supply check, to ensure the long-term stable operation.
2. Operating Specification:
GPRS Type Concentrator
2.1 Main Technical Parameters:
Operating Power:AC220V±20%,50Hz(single Phase)
Upward Communication :GPRS wireless mobile network
Downward Communication:Micropower wireless mode,470.79MHz,1200BPS
Power Consumption :≤10VA

2.2 Working Condition:
Installation position requirements: The installation position must has the China mobile GSM network signal coverage.
Management center requirements:Network server of data management center must has the stable IP address. If has no IP address, it need to equipped with a data transmission terminal (GPRS DTU)
2.3 Operating Method
1)Set up the server IP and address
The default server of concentrator IP: 184.108.40.206,port number:8001, address: 0001, administration division code: 0371.
Set up the parameters of concentrator through RS232 according to stable IP and port of data management center. And set up the address and administration division according to the actual need.
2)Fix the concentrator
Fix firmly on the concentrator according the concentrator fixing hole position. If the concentrator will be installed outside, it need to install in the protective box. Connect the GSM antenna to the antenna terminals at the right side of concentrator, and the radio-frequency antenna connect to the antenna terminals at the left side of concentrator. Insert the GPRS function mobile phone card into the SIM card slot.
The concentrator connect to AC power 220V, 50Hz according to the wiring connection diagram.
4)Set up the concentrator operating parameters
It can set up the parameters after log in the management center. Such as: date and time, meter reading time interval, network maintenance time interval.
5)Download the meter address
Download the collector address of management center software and meter address to the concentrator after finish to set up the operating parameters of concentrator. After finish the downloading, the concentrator can work normally.
2.4 Indicator Light Description
IO0:TCP connection indicator light. When the concentrator connects to the server, the indicator light will turned on. It will not be turn on for other condition.
IO1:PPP connection indicator light.It will be turned on when the mobile phone card registered to the mobile network. It will not be turn on for other condition.
IO2:Operating indicator light. It will glitter under the system normal operating.
IO3:Network status indicator light. It will be turned on during the network time interval. It will not be turn on during other time interval.
IO4:Meter reading time interval indicator light. It will be turned on during the meter reading time interval. It will not be turn on during other time interval.
1) The power cable should adopt the RVVB type 2×0.75mm2 or thicker cable, and install the earth-leakage protective device. The power supply of concentrator should be stable and reliable, to avoid can’t read the meter caused by the power outage.
2)The concentrator can store 31 day freezing data and 12 meter reading day freezing data.If the concentrator will be power off at the freezing time, it can’t produce the freezing data.
3)The concentrator has equipped with 2 antenna. The left side at the top of case connects to the radio-frequency antenna, and the right side connect to the GSM antenna.
4)Only install the antenna and mobile phone card, can power on the concentrator.
5)If the management center adopts the fixed IP mode,need to make sure the IP and port of concentrator is same as the management center.
