​An intelligent device is any device, instrument, or machine that has computing and processing capabilities.

A fully - functional intelligent device must have sensitive and accurate sensing functions, correct thinking and judgment functions, and effective execution functions.

An intelligent device is a product of the combination of traditional electrical equipment with computer technology, data processing technology, control theory, sensor technology, network communication technology, power electronics technology, etc.

Intelligent devices mainly include two key aspects: self - detection is the foundation of intelligent devices; self - diagnosis is the core of intelligent devices.

An intelligent device is a highly automated mechatronic device. Due to its complex structure and important role in the system, there are high requirements for the reliability of intelligent devices. The reliability indicators of electronic products are jointly determined by the reliability of components, technical design, process level, and technical management, etc. To improve the reliability of products, one must master the failure laws of products. Only by comprehensively understanding the failure laws of products can effective measures be taken to improve the reliability of products.

The intelligence of the intelligent device application platform is reflected in the fact that the system composed of heterogeneous devices has the characteristics of context awareness, task migration, intelligent collaboration, and multi - channel interaction.

Context - aware applications can capture, analyze the relationships between multiple objects, and make responses. Device collaboration refers to coordinating the services provided by different devices, integrating the functions of existing available services, and constructing new combined services with more abundant functions. Multi - channel interaction is a human - computer interaction method that uses multiple channels to communicate with a computer, where the "channel" refers to the communication method for users to express intentions, perform actions, or perceive feedback information.
