Smart Meter Advanced Metering Infrastructure With GPRS/RF/PLC Module
1. Brife Introduction:
An AMR/AMI solution is basically consisted of three layers: meter reading and control devices (mainly consisted of meters), communication devices and system/data management center.
Meter reading and control devices are basically consisited of meters with remote and automatic reading functions or features like RS485, RF, PLC, etc. There can be load switch, integrited monitor, data collector, etc.
Communication devices builds the commmunication network or channel between meter and management center. There are normally concentrator, handheld reader (HHU), communication network like GMS/GPRS, PSTN, internet, optical fibre, etc.
Management center are basically consisited of a group of computer hardware like servers, computers, printers, etc and functional software modules or softwares such as the meter (esset) management module, user or customer management module, security and structure setting module, database and report statistic module, etc. The management software can realize both off-line management and on-line management and provide service at 24 hours a day.
2. Concentrator:
2.1 Data Collection Function
The concentrator read the data from the water meter at regular time automatically trough M-BUS line based on preset meter address (physical address) , store the current and historical data and communicate with main station
2.2 Each Concentrator can read 320 pieces water meter
It forward the control command of station to open/close the meter with electric valve.
2.3 Data Storage Function
Concentrator have built-in large volume FLASH with power-off protection function, can store the data more than 10 years. The data will be checked once being stored to avoid being sent with invalid format.
Concentrator also can store the technical parameters meter address and communication protocol etc., which are sent by main station or HHU.
2.4.RTC Function
The built-in RTC (real time clock) in the concentrator meet the different stepped tariff requirement. RTC set and check the time through main station.
2.5. Data Communication Function
It has four communication interfaces to realize the communication among meter, PDA and main station.
Each interface can connect with 80 pieces meters and 320 pieces in total.
Two RS485/232 interfaces is to realize the communication between lines and main station.
2.6. Data Collection And Process
Read the data displayed on the screen of the meter at the fixed time
Read the data displayed on the screen of the meter regularly.
Calculate the current-month water consumption.
The water consumption in the fixed reading time ( the time can be set)
Calculate and analysis the data to judge if the water consumption is abnormal.
3. Main Station
3.1 Communication Mode
RS485 line communication between mains station and concentrator
3.3Reading Method
Main station will read the data out of concentrator.
Concentrator read the data at the fixed time and store them. The main station will send command to read the data in the concentrator through serial channel and store them in the database.
3.4 Main Function
Based on the different zones, you can select the concentrator to read and click on “read now”. The data reading and acquiring of New J10 concentrator is separated, it just display the reading status is failed or sucessful.
