The intelligentization of household appliances is a comprehensive application of information collection, information exchange and information processing skills. The use of intelligent skills can not only make the use of home appliances more complete and more convenient to operate, but also significantly improve the operation economy of home appliances and reduce energy consumption during operation. The primary policy of the measure.





Intelligent concept

The General Administration of Quality Supervision, Inspection and Quarantine and the National Standardization Management Committee agreed to release GB/T28219-2011 "Intelligent Skills for Smart Household Appliances" will be officially implemented on September 1, 2012. According to the definition of the specification, smart home appliances refer to household and similar electrical appliances that use one or more intelligent skills and have one or more intelligent characteristics; intelligent skills are the intersection of artificial intelligence and control. Use skills. Vague control, neural network control and expert control are the most commonly used intelligent skills. It can be seen that the intelligent characteristics mentioned in this specification refer to the characteristics of artificial intelligence, that is, the similar human intelligent behaviors in artificial systems, such as self-learning, self-adaption, self-harmony, self-diagnosis, self-inference, self-organization, self-correction, etc. . It is worth noting that there are no similar international codes and other national codes, and this code is also the first time formulated in China.

GB/T28219-2011 indicates intelligence with "intelligent" in English, but now smart home appliances at home and abroad are mostly referred to as "smart". The latter is not much related to artificial intelligence. The convenience of using performance is usually the primary criterion for measuring the level of “smart”, while the use of convenience is primarily accomplished through active control measures. Of course, having the "intelligent" function is of great significance for improving the "smart" level, but in fact there are not many household appliances with the "intelligent" function. It is a long-term habit in the industry to call "smart" smart. Therefore, most home appliance companies call products with "smart" features smart home appliances. The smart home appliances referred to in this article follow the prevailing name on the market today, and refer to home appliance products that are convenient for use according to information processing functions, regardless of whether they have artificial intelligence functions.

White goods, represented by refrigerators, washing machines, and air conditioners, are the primary energy-consuming appliances. Calculated energy consumption accounts for about 2/3 of the total household electricity consumption, and has always been a focus area for household appliances energy-saving technologies. Since the birth of home appliances, intelligence has been an important issue in the development of home appliance skills. The early intelligence is to use sensitive components to complete the basic control and conditioning functions, instead of manual operation. At this stage, energy saving is not the primary consideration of intelligentization, and ease of operation is the primary policy of intelligentization. With the development of microelectronic skills, intelligence has evolved to complete more complete control and conditioning functions according to established procedures. Especially after the single chip microcomputer is widely used in the field of home appliances, the ability of home appliances to actively and optimally continue to improve. People will make these products have more perfect technical measures of active control function, commonly known as "intelligence". At this stage, energy saving and operating economy have become the goals of control and conditioning design. In the 21st century, the development of information skills has promoted the further improvement of the control system. Better information collection, information exchange, and information processing skills not only make the use conditions of artificial intelligence skills gradually sophisticated, but also make the functions of home appliances continue to improve. Without the support of relying on artificial intelligence skills, the independent optimization of home appliances can make significant progress.

The foundation of the intelligentization of household appliances includes three aspects: information collection, the use of various sensitive devices and sensors to obtain environmental and target information; information exchange, the use of information transmission methods, the use of internal or external corresponding components, systems to determine or adjust the operation Information required for the situation; information processing, processing the input environment and target information, internal information of the appliance, and control instructions and other information from outside the appliance, including the use of artificial intelligence methods and other technical methods, output performance components, system control, Conditioning instructions and descriptive information about the condition of the appliance, etc. The artificial intelligence skills defined in GB/T28219-2011 mainly focus on the artificial intelligence skills of information processing, which is smaller than the intelligent concept of this article.
