[0003] At present, the single live wire temperature measurement panel separates the temperature sensor from the integrated circuit board to reduce the influence of the heat generated by the integrated circuit board on the temperature sensor. The defect is that this single live wire temperature measurement panel is only a structural improvement , did not consider the influence of the heating of the integrated circuit board current components on the temperature measurement, and did not substantially solve the influence of temperature rise

The invention discloses a method and system for correcting the temperature measurement error of a single-live line switch and belongs to the technical field of smart homes and household appliances. The method comprises the following steps that: a historical data set is acquired under the condition that room temperature is kept constant; segmented linear fitting is carried out on data under a power-on state through the historical data set, and segmented fitting is carried out on data under a power-off state through the historical data set, and a temperature rise segment time point and a temperature drop segment time point are determined; in the first power-on / power-off process of a current user, the approximate regression coefficient of each straight line under the power-on state and the approximate regression coefficient of each straight line under the power-off state are calculated in a segmented mode according to the temperature rise segment time point and the temperature drop segment time point; the temperature measurement error of the single-live line switch is corrected according to the temperature rise segment time point, the temperature drop segment time point, the approximate regression coefficient of each straight line under the power-off state and the approximate regression coefficient of each straight line under the power-off state. With the method and system of theinvention adopted, the problem of temperature measurement error caused by the heat emission of the integrated circuit board of the single-live line switch can be substantially solved.
Description
technical field [0001] The invention relates to the technical field of smart home appliances, in particular to a method and system for correcting temperature measurement errors of a single live wire switch. Background technique [0002] The integrated circuit board of the single live wire switch will generate heat when it is powered on. Since the switch is aimed at different user families and the current is different, the heat generated is also different. For different users, in the case of current flow, the error of the device to the actual measured temperature is different. [0003] At present, the single live wire temperature measurement panel separates the temperature sensor from the integrated circuit board to reduce the influence of the heat generated by the integrated circuit board on the temperature sensor. The defect is that this single live wire temperature measurement panel is only a structural improvement , did not consider the influence of the heating of the in...
