LoRa Wireless Meter Reading Solution

I. System Overview

The HAC-ML (LoRa) meter reading system is an overall solution based on the LoRa technology for low-power smart remote meter reading applications. The solution consists of a meter reading management platform, a concentrator, a near-end maintenance handheld RHU and a meter reading module.

The system functions cover acquisition and measurement, two-way communication, meter reading control valve and near-end maintenance etc to meet the needs of remote meter reading applications.

II. System Components

HAC-ML (LoRa) wireless remote meter reading system includes: wireless meter reading module HAC-ML, Concentrator HAC-GW-L, handheld terminal HAC-RHU-L, iHAC-ML meter reading charging system (WEB server).

● The HAC-ML low-power wireless meter reading module: Sends data once a day, it integrates acquisition, metering and valve control in one module.

● HAC-GW-L Concentrator: Supports up to 5000pcs meters, store 5000 uplink data and query the saved data through the Server.

● HAC-RHU-L handheld terminal: Set parameters such as meter ID and initial reading etc, set the transmit power of the HAC-GW-L concentrator wirelessly, used for mobile handheld meter reading.

● The iHAC-ML meter reading charging platform: Can be deployed on the cloud platform, the platform has powerful functions, and big data can be used for leakage analysis.
