A control method for emergency water use

Abstract

The invention relates to the field of intelligent water meters, and especially relates to an emergency water utilization control method applied to an intelligent water meter. When a user needs water in emergency, but the valve of the intelligent water meter is closed, and no water is available for a period of time, the user carries out button operation through a touch button arranged on the valve of the intelligent water meter, when the touch button monitors the button operation, whether the user is under the above condition or not is determined by judging whether the intelligent water meter corresponding to the touch button is in an arrearage state, and human maloperation and wrong responses can be avoided; when it is determined that the intelligent water meter is in the arrearage state, the valve of the intelligent water meter is opened, after the valve is opened, only a certain amount of water is provided, then the valve is automatically closed, the certain water amount serves as the emergency water utilization amount of the user, afterwards the user needs to make a supplementary payment for the cost corresponding to the emergency water utilization amount, and therefore benefits of the water supply company are not greatly influenced, and the condition that the user needs water in emergency is achieved.

Description

Technical field [0001] The invention relates to the field of smart water meters, in particular to a method for controlling emergency water used in smart water meters. Background technique [0002] Smart water meters are mainly used in the northern market of my country. They are residential water metering and water supply on-off terminals used according to the collection of residents' water fees.
