Fault detection method and system for smart water meter and readable storage medium

The invention discloses a fault detection method for an intelligent water meter, which connects the water meter with a water source, and comprises the following steps of: acquiring the flow measured by the water meter for multiple times within a specified time to obtain a plurality of pieces of flow information; averaging the multiple pieces of traffic information to obtain detection traffic information; comparing the detection flow information with preset flow information of the water source, and judging whether the water meter fails or not according to a comparison result. According to the fault detection method of the intelligent water meter, when the detection flow information is compared with the preset flow information of the water source, whether the water meter breaks down or not can be judged according to the fluctuation interval range, when the fluctuation value falls into the preset fluctuation range, it can be understood that the water meter does not break down, and otherwise it is considered that
