LoRa/NB-IoT wireless relay meter reading system

Product Model: HAC-WL8

　　The HAC-WL8 meter reading system is designed to solve the problem of signal blind spots in underground garages, underground wells and other places in the NB-based meter reading system, which affects the overall success rate of meter reading. The meter-side data of the system is reported by the LoRa low-power small wireless meter reading module. After the NB/LoRa dual-mode repeater receives the data through LoRa, it is reported to the platform through NB. The system supports downlink reading and valve control, and supports infrared and upgrade functions. Through the setting of the whitelist, a dual-mode relay can be bound to 8 meter terminals.

Product details

system introduction

System composition: HAC-WL8 low-power wireless LoRa meter reading module, HAC-GWN low-power LoRa/NB repeater, HAC-RHU handheld, HAC-WL8 meter reading management platform.

· The HAC-WL8 low-power wireless LoRa meter reading module actively sends meter data once a day, and can be woken up through the wireless LoRa/NB repeater to control valves, click and set.

· The HAC-GWN low-power LoRa/NB repeater uses a one-time lithium battery, does not require solar energy and external power supply, is small in size, easy to install, simple to maintain, easy to expand, and flexible to deploy; outdoor waterproof housing, can work at a minimum of minus zero 20°C.

· HAC-RHU handheld is used for near-end infrared meter reading and upgrading, parameter setting of field meter terminals and repeaters.

· HAC-WL8 meter reading management platform can be deployed in the cloud, and the application platform has rich functions. Provide dynamic data link library to facilitate customer development.

Features

· Ultra-low power consumption: using capacity-type ER18505 battery + 0.47F super capacitor, the service life can reach 10 years;

· Easy access: no need to rebuild the network, it can be directly used for commercial use with the operator's existing network;

· Large capacity: store 10-year monthly frozen data and 12-month daily frozen data;
