Abstract

This invention discloses a method and system for identifying and repairing ultrasonic water meter wave skipping types. The method includes: S1. Acquiring multiple sets of continuously sampled time-of-flight data, each set including upstream and downstream flight times; S2. Calculating the wave skipping multiple based on one set of flight time data and a preset estimated ultrasonic signal period; S3. Acquiring the current water temperature and calculating the theoretical value of the downstream flight time based on a pre-stored temperature compensation model, comparing the actual measured downstream flight time with the theoretical value to obtain the temperature deviation; S4. Determining the current wave skipping type from a preset range of wave skipping types based on the wave skipping multiple and the temperature deviation; S5. Based on the determined wave skipping type, calling the corresponding repair strategy to repair the current set of flight time data.
