Abstract

The invention discloses a swing type infrared temperature measurement device-based refrigerating box temperature control method. The method comprises the steps of 1, powering on and initializing all components; 2, setting a preset temperature range; 3, monitoring the temperature in real time by a temperature measurement device; processing a signal by a processor; and repeating the step 3 when the measured value of the temperature is within the preset temperature range; otherwise, conducting the step 4; 4, sending an alarm signal to an alarm device by the processor; and determining the coordinates of an abnormal temperature point relative to the corner of a cabinet by the processor according to the geometric method; 5, according to different judgments on whether the temperature signal is larger than a maximum temperature value or not, sending different control signals to an axial-flow fan and a refrigerating machine by the processor so as to drive the axial-flow fan and the refrigerating machine to run; 6, manually removing the alarm and repeating the step 3. According to the technical scheme of the invention, the temperature detection is realized. Meanwhile, based on data detected by the temperature measurement device, the temperature control and the abnormal alarm are enabled.

Description

【Technical field】

[0001] The invention relates to the technical field of temperature control, in particular to the technical field of a method for controlling the temperature of a refrigerator based on a swing-type infrared temperature measuring device. 【Background technique】

[0002] A refrigerator is a box-like cubic housing used to store items for refrigeration. Refrigerators are widely used in cold chain transportation. Items that usually need to be transported in the cold chain, such as vegetables, seafood, medicines, blood, etc., need to be stored within a certain temperature range, so as to ensure that they will not deteriorate during transportation. In order to achieve storage in a certain temperature range, it is necessary to enable the inside of the refrigerator to have the ability to maintain a certain temperature range.

[0003] In the refrigerator, the existing detection system usually installs various temperature sensors inside to achieve the purpose of detec...
