Description

Technical Field

[0001] The utility model relates to the technical field of smart home, in particular to a washing machine access circuit based on BLE and WIFI communication. Background Art

[0002] With the rapid development of science and technology and the improvement of people's quality of life, smart home technology has gradually become an important part of modern families. As a member of the smart home system, the intelligence and networking of washing machines have also received widespread attention. Most traditional washing machines can only perform simple local operations and cannot achieve remote control and intelligent management, which to a certain extent limits the user experience.

[0003] In recent years, the development of wireless communication technology has made it possible for washing machines to be intelligent. Among them, BLE (Bluetooth Low Energy) and WIFI technology are two important communication methods. BLE technology has been widely used in small-scale communications between smart home devices due to its advantages of low power consumption, high speed and low cost. WIFI technology can connect devices to the Internet, allowing users to remotely access and control devices through smartphones or other smart terminals.

[0004] Therefore, a washing machine access circuit combining BLE and WIFI technology came into being. This circuit can not only realize the wireless connection and control of washing machines with mobile devices such as smartphones, but also exchange data with remote servers through the Internet to realize functions such as remote monitoring, fault diagnosis and firmware updates. At the same time, the access circuit can monitor the running status of the washing machine in real time and intelligently manage it, which can effectively improve the use efficiency of the washing machine and the quality of life of users.

[0005] However, most of the washing machine access circuits on the market currently have single functions and poor scalability, which cannot meet the diverse needs of users for intelligent and networked washing machines. Therefore, developing a washing machine access circuit based on BLE and WIFI communication to achieve remote control, intelligent management and function expansion of washing machines has important practical significance and application value.

[0006] In summary, the research and development of washing machine access circuits based on BLE and WIFI communication is an important research direction in the field of smart home and Internet of Things technology, and is also an important means to improve the quality of life of users and promote the intelligent development of the home appliance industry.
