Description

An Intelligent Prepaid Water Meter System

technical field

The utility model belongs to the technical field of water meters and relates to an intelligent prepaid water meter system.

Background technique

With the continuous development and progress of society and the continuous improvement of Internet of Things technology, the amount of energy used in households or industries has also increased rapidly. The traditional meter reading statistics mode can no longer meet the growing needs of usage statistics and modern management. The traditional water meter data collection scheme relies on manual reading of the records in front of the dials of each user's home. The labor load of the staff is large, the error rate is high, and the statistical data cycle is long, which greatly hinders the development of the meter reading management system.

At present, although prepaid water meters can realize "pay first, use later", there are still some shortcomings. Existing prepaid water meters generally use near-end alarms. When the remaining water volume is less than the set water volume parameters, the alarm will send out an alarm reminder at the near-end. Due to the busy work of users, there are often old people and children at home. When the alarm reminder is issued due to insufficient water supply, the user cannot understand the alarm information in time, resulting in missing the payment time. If the user encounters an urgent need for water, and the prepaid water is suddenly used up, the user needs to go to the water management department to recharge before using water again. This brings great inconvenience to the user.

In order to prevent users from receiving payment reminders in time, an intelligent smart prepaid water meter system is designed first, which can realize both remote and short-distance alarm reminders.
