Problems solved by technology

Because it is difficult for ordinary users to buy this kind of high-energy lithium battery in the market, even if they can buy it, the assembly of the battery is another problem, which causes inconvenience to the user and causes a great burden for the manufacturer. The battery fails prematurely, and this contradiction will be more prominent

Abstract

The invention discloses an intelligent water meter. The intelligent water meter comprises a microprocessor, a valve, a flow sensor, an IC card reader-writer, a displayer and a first power supply, andfurther comprises a second power supply. The second power supply is connected with a user power utilization circuit. When the user power utilization circuit works normally, the second power supply provides electric energy; when the user power utilization circuit is abnormal, the first power supply supplies electric energy to the second power supply. Two sets of power supply systems are arranged inthe intelligent water meter, and the replacement frequency of a battery in the intelligent water meter is reduced; under normal circumstances, the user power utilization circuit provides the electricenergy for the intelligent water meter, the service life of the battery in the intelligent water meter is prolonged, and the intelligent water meter is more convenient for users to use.

Description

technical field [0001] The embodiments of the present invention relate to the field of instruments, and in particular to an intelligent water meter. Background technique [0002] Smart water meters are formed by adding electronic control devices and electric valves on the basis of mechanical water meters. But there are not many products that can work stably and reliably for a long time. [0003] Generally, the installation environment of water meters is relatively humid, and most smart water meters are powered by batteries. For a long time, most manufacturers have used built-in high-energy lithium batteries to power water meters, which can provide as much power as possible and prolong the service life of water meters. Because it is difficult for ordinary users to buy this kind of high-energy lithium battery in the market, even if they can buy it, the assembly of the battery is another problem, which causes inconvenience to the user and causes a great burden for the manufact...
