Abstract

The invention provides a waterway abnormality detection method and device. The abnormal detection method of the waterway includes: using multiple pressure sensors to collect multiple pressure values, wherein the waterway includes a main water valve, an external water source, and multiple pressure sensors arranged on the side of the main water valve away from the external water source; The average value of each pressure value; determine whether the absolute value of the difference between each pressure value and the average value is smaller than the preset pressure difference; and if not, determine that the waterway is abnormal. According to the solution of the present invention, by judging whether the multiple pressure values ​​at different positions of the waterway are all near the average value, it is possible to determine whether there is any abnormality in the waterway on the side of the main water valve away from the external water source, so that the waterway leakage can be found in time, and the long-term waterway leakage can be avoided. Serious losses to users.

Description

technical field [0001] The invention relates to the field of water leakage detection, in particular to a waterway abnormality detection method and device. Background technique [0002] With the development of society and the continuous improvement of people's living standards, people's pace of life is getting faster and faster, so they are more and more willing to buy a lot of food and put it in the refrigerator. The refrigerator has become one of the indispensable household appliances in people's daily life. . [0003] Moreover, current refrigerators have more and more functions to meet different needs of users. For example, a refrigerator equipped with an ice-making system can provide ice cubes to users. In the ice-making system of the refrigerator, the waterway is a key system component. If the waterway leaks or fails, it will lead to serious consequences. The current ice-making system cannot monitor, discover and prevent waterway leakage, and it is easy to affect the w...
