Overview of Wireless Remote Water Meter (LoRa) System

The meter reading management and control system consists of a computer system, system management software, application software, and database. The main functions include: archive management, operation management, statistical analysis, data export, and other functions. The system adopts a B/S architecture design, and uses two methods to read on-site data. One is to communicate with the on-site concentrator through GPRS and read on-site data; Another way is to read data through a handheld device. The powerful management and control functions of the system enable the management department to break free from tedious manual copying and primitive user fee management methods, achieving modern fee management.

Functional features:

1) The wireless remote water meter is equipped with a valve, and the system can control the opening and closing of the valve in real time;

2) The meter adopts Lora transmission mode, and after installing a relay, it can greatly extend the communication distance;

3) Handheld devices can be used to set up measuring instruments, query raw data, and read meter data;

4) The module has a power-off storage function, and the power-off data is not lost. After power is restored, it can operate normally;

5) The communication distance of the wireless module is optimized according to different requirements, and the communication distance is not less than 1000 meters;

6) The overall circuit is designed with ultra-low power consumption and powered by high-capacity lithium batteries, with a battery life of over 6 years;

7) The connection between the RF module and the base table adopts an integrated structure with a built-in antenna to reduce antenna damage during installation;

8) Equipped with battery voltage detection function, it can upload to the management platform in a timely manner when the battery is running low, making it convenient for managers to discover problems;

9) The module adopts a deep sleep period design, which can completely shut down the wireless module during the deep sleep period, greatly reducing power consumption;

10) It has anti magnetic interference function. When two reed switches are affected by magnetic interference and are simultaneously closed, the valve will automatically close. After the interference disappears, it will automatically open;
