Trending Products Hac amr module - LoRaWAN Dual-mode Meter Reading Module – HAC

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.
