The HAC-WE low-power consumption wireless meter reading system utilize the network toplogy of LPWAN+LPLAN.The system contains acquisition,measurement,bidirectional communcation,and valve on/off remotely,featuring strong real time performance,low power consumption,big data sampling,high reliability,which is flexible to build up and covenient for dismantling and maintenance as well, there is no blind zone for meter reading especially suitable for metering the super-coverage requirement of a low density residential area.
LPWAN+LPLAN low power Automatic Meter Reading(AMR)system inculdes HAC-WE low power AMR module,HAC-nLSlow power mini base station,and HAC-RHU handheld unit,and metering platform.
The wireless reading reports data very four hour and the metering plaftform receives readout 6 times a day, 240 packets in total. 3.6Ah lithium batteries life of more than 10 years can be supported for a wide range of use cases.
The power of HAC-nLS mini base station is provided by both solar panels and lithium batteries,making it work well without urban power grids. The mini base station is convenient for dismantling and maintenance .One mini base station is able to connect with 20 to 200 meters simultanously.
HAC-RHU portable reading device is hand-held,which helps to do meter reading for dead spots,parameters of the meter can be set by handheld unit on site.
HAC metering system can be easily installed and be safely used on a cloud platfrom,making it flexible to build up.
