New Arrival China Nb Iot Smart Module - LoRaWAN Dual-mode Meter Reading Module – HAC Detail:

System Components

HAC-MLLW (LoRaWAN dual-mode meter reading module), HAC-GW-LW (LoRaWAN gateway), HAC-RHU-LW (LoRaWAN handhels) and data management platform.

System Features

1. Ultra long distance communication

  • LoRa modulation mode, long communication distance.
  • Visual communication distance between Gateway and Meter: 1km-5km in urban environment, 5-15km in rural environment.
  •  The communication rate between the gateway and the meter is adaptive, realizing the longest distance communication at a low rate.
  • The handhelds has a long supplementary reading distance, and batch meter reading can be carried out by broadcasting within a range of 4km.

2. Ultra-low power consumption, long service life

  • The average power consumption of the dual-mode meter-end module is less than or equal to 20µA, without adding additional hardware circuits and costs.
  • The meter module reports data every 24 hours, powered with an ER18505 battery or equal capacity can used for 10 years.

3. Anti-interference, high reliability

  •  Multi-frequency and multi-rate automatic switching to avoid co-channel interference and improve transmission reliability.
  • Adopt the patented technology of TDMA communication to automatically synchronize the communication time unit to avoid data collision.
  • OTAA air activation is adopted, and the encryption key is automatically generated when entering the network.
  •  The data is encrypted with multiple keys for high security.

4. Large management capacity

  • One LoRaWAN gateway can support up to 10,000 meters.
  •  It can save 10-year annual frozen and monthly frozen data for the last 128 months. The cloud platform can query historical data.
  • Adopt the adaptive algorithm of transmission rate and transmission distance to effectively improve the system capacity.
  •  Easy system expansion: compatible with water meters, gas meters and heat meters, easy to increase or decrease, gateway resources can be shared.
  • Compliant with the LORAWAN1.0.2 protocol, the expansion is simple, and the capacity can be increased by adding a gateway.

5. Easy to install and use, high success rate of meter reading

  • The module adopts OTAA network access method, which is easy to operate and easy to maintain.
  •  Gateway with multi-channel design can simultaneously receive data of multi-frequency and multi-rate.
  • The meter-end module and the gateway are connected in a star network, which is a simple structure, convenient connection and relatively easy management and maintenance.
