Humidifier water level monitoring method based on least square method

Abstract

A humidifier water level monitoring method based on a least square method is characterized in that during work, the whole process from heating to dry burning is monitored in a segmented mode, the first stage is a temperature rising stage, temperature rising sampling values of a bottom plate of a heating disc are monitored, data fitting is conducted on the temperature rising sampling values and the corresponding collecting time through the least square method, and the temperature rising sampling values are obtained; and calculating the temperature rise slope K1, and comparing the temperature rise slope K1 with the dry burning slope K0 to judge whether the temperature rise slope K1 exists or not. The second stage is a temperature stabilization stage, the heat sampling values of the bottom plate of the heating plate are detected, data fitting is conducted on the heat sampling values and the corresponding collection time through the least square method, the heat slope K2 is calculated, and whether water exists or not is judged by judging whether the heat slope K2 is zero or not. And when water exists, estimating the residual water amount in the water storage tank and the use time, and displaying a result. According to the scheme, whether water exists in the water storage tank or not can be accurately judged, and the remaining water amount and the use time can be estimated. Convenience is brought to use, and the intelligent level of the humidifier is reflected.

Description

technical field [0001] The invention relates to the field of humidifier monitoring, in particular to a method for monitoring the water level of a humidifier based on the least square method. The monitoring method can not only judge whether there is water in the humidifier, but also can estimate the remaining water volume and use time in the humidifier, which brings great convenience to the use of the humidifier. Background technique [0002] In modern clinical medicine, the ventilator, as an effective means of artificially replacing the spontaneous ventilation function, has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support treatment and emergency resuscitation. It occupies a very important position in the field of modern medicine. Ventilator is a vital medical equipment that can prevent and treat respiratory failure, reduce complications, save and prolong the life of patients. [0...

Problems solved by technology

[0007] The present invention provides a method for monitoring the water level of a humidifier based on the least squares method. Its first purpose is to solve the problem that the existing indirect method for detecting the water level of a humidifier cannot predict the remaining water volume and the use time of the humidifier. The second purpose is to To solve the problem of low accuracy in the existing method of indirect detection of humidifier water level
