Embodiment Construction
[0036] The implementation of the intelligent on-site heat source detection system and method of the present invention will be described in detail below with reference to the accompanying drawings.
[0037] Gas compression refrigerator: It relies on the heat absorption of low-boiling liquid refrigerant (such as Freon R12) to achieve the purpose of refrigeration, and then evaporates and compresses it with a compressor, and then makes it release heat and liquefy, thus completing the refrigeration cycle. . Because the theory and production technology of this kind of refrigerator are relatively mature in terms of technology and have a long service life, more than 90% of the refrigerators produced in China are of this type.
[0038] Gas absorption refrigerator: It is powered by a heat source, commonly used as a refrigerant with ammonia, and hydrogen that can cause liquid ammonia to evaporate is used as a diffusing agent, and a refrigerator that uses a mixed solution of ammonia, wate...

The invention relates to an intelligent on-site heat source detection system, and the system comprises a data storage chip which is used for storing the geometric distribution shape and color imaging characteristics of steam; a steam recognition mechanism used for recognizing a pattern which simultaneously corresponds to the geometric distribution shape of the steam and the color imaging feature of the steam in the received current lifting image as a steam pattern; and an effective analysis equipment used for detecting the number of the pixel points occupied by the steam pattern and sending a heat source identification instruction when the number of the pixel points occupied by the steam pattern exceeds the limit. The invention further relates to an intelligent on-site heat source detection method. The intelligent on-site heat source detection system and method are compact in logic and stable in operation. On-site detection is carried out on the heat source in a refrigerator based on the steam imaging characteristics, and a user of the refrigerator is notified in time when the heat source is detected, so that heat source equipment is prevented from influencing the operation of the refrigerator, and overheated food is prevented from being put into the refrigerator.
Description
technical field [0001] The invention relates to the field of household appliances, in particular to an intelligent on-site heat source detection system and method. Background technique [0002] Household appliances, referred to as home appliances, refer to appliances driven by electric energy (or mechanized actions), which can help perform household chores, such as cooking, food preservation or cleaning. In addition to the home environment, they can also be used in companies or in an industrial environment. Basically, home appliances are divided into large appliances (white appliances, black appliances) and small appliances. [0003] A few years ago, in the eyes of consumers, "high-end home appliances" were only luxuries enjoyed by social minorities. The reason is naturally that "high-end" and "high price" are basically the same. With the diversification and serialization of "high-end home appliances", especially when consumers start to pay attention to improving their qu...
