A method for detecting urine wetness

Abstract

The invention provides a urination-caused wetting detection method and apparatus. The method comprises: relative humidity values are collected by a sampling period Ts and a detection sensitivity value is set, wherein the Ts is less than or equal to 5s; the collected relative humidity values are filtered; according to filtered data, a relative humidity changing gradient is calculated; and if the relative humidity changing gradient is detected to be larger than the detection sensitivity value more than successive two times, urination alarming is carried out; and otherwise, a relative humidity value is collected again. The method and apparatus have the following advantages: the influence on the detection effect by environment factors can be reduced; the changing actual environment demand can be satisfied; the detection performance can be improved; a problem that data reporting fails because the data can not be transmitted to the user phone when wireless connection can not be carried out as well as a problem of spurious triggering or multi-times alarming for one-time urination can be solved; and intelligent multi-times detection can be carried out on the urination behavior.

Description

Technical field [0001] The invention relates to a detection method, in particular to a urine wetness detection method. Background technique [0002] Infants, young children, and the elderly who cannot take care of themselves need to change their diapers in time after urination, otherwise it will cause various diseases such as eczema. Because the urination time is uncertain, it puts a heavy burden on the guardian. Therefore, how to effectively and timely monitor their physical condition and effectively improve the work efficiency and service quality of medical staff and their families has become an urgent problem to be solved. [0003] At present, most of the devices on the market that monitor urination monitor urination behavior by detecting the relative humidity value. When the relative humidity value exceeds the humidity threshold, it will alarm and use wireless technology such as Bluetooth to transmit data. However, these methods have the following problems: [0004] (1) Usually...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to address the above problems and difficulties, overcome the problem in the prior art that the use of fixed humidity threshold detection cannot adapt to different humidity environments and affect the detection effect, and provide a urine wetness detection method
