An intelligent control ultraviolet light-emitting device comprises an intelligent control module, an ultraviolet light source module, a user interaction module, an environment sensing module, a position or angle adjusting module, a log storage and query module, a communication control module and a power management module. The intelligent control module intelligently executes a light emitting strategy by matching detection data of the environment sensing module with an ultraviolet attenuation prediction model and a control strategy algorithm, and supports semi-intelligent execution of parameters input by a user after operation processing; and the system can automatically evaluate the irradiation distance and time according to environment sensing data, so that the system is scientific and safe, energy is saved, and the service life of equipment is prolonged. The communication module is convenient for coordination and remote control when being integrated with other systems, such as automobiles, dryers, public transport means, handheld equipment, air conditioners, fresh air systems and the like. An execution mechanism is used for adjusting the irradiation angle and position, saving the use amount of equipment and expanding the irradiation range. The power management module supports the functions of working state monitoring and automatic abnormity processing, and is beneficial to safe use.
