Title:
REFRIGERATOR AND INFRARED SENSOR-BASED METHOD FOR TEMPERATURE MEASUREMENT
Document Type and Number:
WIPO Patent Application WO/2016/206218
Kind Code:
A1
Abstract:
Provided are a refrigerator, and a method for temperature measurement based on an infrared sensor (130). The method for temperature measurement based on an infrared sensor (130) comprises: using an infrared sensor (130) to sense the temperature inside a preset zone; acquiring at predetermined time intervals the sensed result of the infrared sensor (130) to obtain sample temperature values; obtaining a continuous predetermined quantity of sample temperature values and filtering the maximum sample value and the minimum sample value out of the obtained sample temperature values; calculating the average value of sample temperature values after having filtered out the maximum sample value and the minimum sample value, and taking the average value to be the measured temperature value of the infrared sensor (130). Using the solution of the present invention, it is possible to prevent fluctuations in the values measured by the infrared sensor from affecting measurement accuracy; thus the accuracy of temperature measurement is improved, such that measured values directly reflect the actual temperature of the items inside a preset zone, and an accurate basis for control is provided for subsequent associated control.
