Description

Hot water kettle control method based on Internet of things change and hot water kettle Technical Field The invention relates to the field of household appliance control, in particular to a thermos control method based on the change of the Internet of things and a thermos. Background Along with the rapid development of the internet of things technology, intelligent household appliances gradually enter thousands of families, and the hot water kettle is used as a small household appliance with extremely high use frequency in daily life, and the intelligent upgrading of the hot water kettle is also of great concern. However, the intelligent thermos control system in the prior art still has a plurality of limitations, and is difficult to meet the increasing personalized and intelligent demands of users. The intelligent thermos on the current market mainly has the following problems: first, environmental adaptability is poor. The traditional thermos is only provided with a fixed boiling point (usually 100 ℃) and cannot be automatically adjusted according to environmental factors such as altitude, air pressure and the like. In the plateau area, the actual boiling point of water can be obviously reduced (for example, at the altitude of 3000 m, the boiling point is about 90 ℃) due to the reduction of the atmospheric pressure, so that the traditional kettle has a false boiling phenomenon, the expected heating effect cannot be achieved, and the use experience can be influenced due to the false triggering of the dry burning protection. While some high-end products are equipped with barometric pressure sensors, data accuracy and reliability are limited depending on the environmental perception of a single device only. Second, network dependencies are strong and lack synergy. The existing intelligent thermos depends on stable Wi-Fi connection to realize a remote control function, and when a network fluctuates or is interrupted, the intelligent characteristics basically fail. Meanwhile, each device operates in isolation and cannot form effective coordination with other intelligent household devices. For example, multiple kettles may be operated at high power at the same time, resulting in overload of the home circuit, or the water demand cannot be predicted according to the actual position and behavior pattern of the user, resulting in energy waste. Disclosure of Invention The embodiment of the invention provides a thermos control method based on the change of the Internet of things and a thermos, which are used for realizing the intelligent thermos control method of distributed collaborative decision by fusing multisource environment information and behavior data according to the dynamic change of the network topology of the Internet of things so as to improve the environment adaptability, network robustness and user service experience of the intelligent thermos and optimize the energy use efficiency.
