Low Power AMR Solutions

Low power wireless meter reading
The system of two-way radio communication, metering, control valve, meter and control into an organic whole, low power consumption, low cost, small volume, convenient installation, simple maintenance and copy read high success rate.
Use huaao patent arouse method, can achieve low power consumption at the same time and control valve, meter response speed of system characteristics.
Huaao company meter reading system compatibility strong, can connect different type meter, configure the best solution according to customer's demand.
Statement:  wireless meter reading system using wireless wake method for communication technology co., LTD shenzhen huaao international invention patent.
System features:
Narrowband frequency hopping spread spectrum technology being:
Narrow-band high sensitivity, strong penetrating power, frequency hopping spread spectrum, same frequency interference resistance is strong, effective guarantee the communication distance and reliability;
A wide being depress electric power design:
-  emission module: 2.8 ~ 6 v DC voltage range, the static current eight mu A or less, the average power consumption of 25 mu, or less maximum transmitted pulse current 70 ma, or less control valve current 500 ma or less; Table module active reporting data every day, automatic switch valve once every half a month, if once again wake up the meter reading and on-off valves 1 month, using 3.6 Ah ER18505M power battery, use only 50% according to the actual capacity of battery, the battery's working life is more than 8 years.
A patent being awakened method:
Huaao patent wake up methods of independent research and development, don't wake up, the power consumption under control. Wake up the window time is less than 3 milliseconds, awakens the window time reduced 50% than that of the traditional methods, effectively reduce the power consumption. Handsets and concentrator of sensei meter reading cycle (d - MD module for 8 seconds, real-time meter reading is strong.
Nurture a variety of meter reading way:
A.H AC - MD_S module every 4 hours or every measuring 0.5 will take the initiative to report the current measurement data and status;
B. concentrator copy to read and control valve, concentrator or repeater direct communication with the table side module, visibility of more than 2000 meters;
C. handsets site copy to read and control valve, hand-held in table module communication sights of more than 1500 meters.
A control valve being function:
-  wireless meter reading module, control valve circuit can use concentrator or hand-held remote wireless control valve; Easy to extend the prepaid control valve function.
System equipment is complete, fully functional:
-  wireless transceiver module: support of single/double reed pipe metering, can be customized direct reading way; Two-way communication; Soft clock; Power management; Break line detection; Magnetically attack; The disassembly (choose);
- PDAD handsets: wireless Settings (d - MD module ID, pulse constant parameters, such as wireless awaken (d - MD module, complete copy to read and control valve; Set the operation is fast, accurate, convenient, free disassembly;
- RPD Repeaters: extensible fixed-point communication distance meter reading, solve the problem of blind area;
- GWD concentrator: through the GPRS network to upload data to a remote server, make private copies under tables and control valve orders;
- simple WMB_MRD concentrator: local server via M_BUS agreement cable connection.
-  two-way low-power wireless moisture meter, meter module
