LORA water meter module
The LoRa wireless remote meter reading system integrates data collection and measurement, bidirectional communication, and meter reading control valves. The system includes a wireless meter reading and collection module, a concentrator, and a handheld meter reading terminal for the meter reading and charging system (WEB server).
Technical specifications:
1)Transmission distance: Line of sight communication distance between Ml and concentrator ≥ 7000 meters
2)Working frequency range: 470~510MHz
3) Modulation method: LoRa technology
4) Communication method: Integrated transmission and reception
5) Effective transmission power: 17dBm (50mW)
6) Emission current: ≤ 130mA
6) Emission current: ≤ 130mA
7) Receiving current: ≤ 20mA
8) Sleep current: ≤ 8μA
9) Average power consumption: ≤ 20μA
10) Voltage range: 2.8-6.0VDC
Functional features:
1) Ultra long distance communication
LoRa modulation method, with long communication distance.
Communication distance between concentrator and meter: 3-5km in urban environment; Rural environment 10-15km.
Communication distance between handheld device and meter: 3km.
2) Ultra low power consumption, long service life
The average power consumption of the meter module is ≤ 20uA.
Three working modes of the system: LOP1、LOP2、 LOP3, Response time: 12 seconds 24h-12s, 24h; According to ER18505, the battery only uses 50% of its capacity, and the service life of the meter end module is 8 years, 10 years, and 12 years, respectively. In practical use, users can switch any working mode by themselves through the concentrator.
3) Anti interference, high reliability
Frequency hopping technology avoids co frequency interference and improves transmission reliability.
Adopting patented technology of TDMA time-division multiple access communication, automatically synchronizing communication time units to avoid data collisions
Adopting adaptive algorithms for transmission rate and transmission distance, anti-interference, and increasing system capacity
4) Large management capacity
The concentrator can support up to 5000 meters for management. Concentrator stores 5000 flow data; Store frozen data for each table for 10 years and the most recent 12 months
Adopting adaptive algorithms for transmission rate and transmission distance to effectively improve system capacity.
Easy system expansion: compatible with water, gas, and heat meters, easy to add or remove; Adjacent communities can share concentrators.
5) Easy installation, high success rate of meter reading
Dual mode meter reading: 24-hour active reporting of measurement and collection data; Real time meter reading control valve (on/off valve).
Concentrator with multi-core RF design, capable of simultaneously receiving data from multiple frequency points and rates.
Handheld device with supplementary and point reading functions.
