Abstract

The invention discloses a closestool control method and system based on a millimeter wave radar. The method comprises the steps that: S1, a DFFT data frame sent by the millimeter wave radar is acquired; S2, the DFFT data frame is processed, and whether a person exists in a sensing area is judged; and S3, if someone exists in the sensing area, a toilet lid is opened, gesture recognition is performed, and corresponding actions are executed. The method and system of the invention have the advantages of low cost, no light influence, no need of opening holes, insensitivity to temperature change, large detection area and the like.

Description

technical field [0001] The invention belongs to the technical field of digital signal processing, and in particular relates to a toilet control method and system based on millimeter wave radar. Background technique [0002] Millimeter waves refer to electromagnetic waves with a wavelength from 0.1 to 1 cm, and the corresponding frequency range is 30 to 300 GHz. Millimeter wave radars are widely used in fields such as intelligent perception and interaction, intelligent robots, and automotive radar. The millimeter-wave radar chip is one of the core components of the millimeter-wave radar. As the integration of the millimeter-wave radar chip becomes higher and higher, the millimeter-wave radar chip realizes more and more functions, and integrates more dedicated digital data into the chip. Signal processing hardware acceleration unit. The highly integrated millimeter-wave radar chip greatly simplifies the system development complexity of millimeter-wave radar, and at the same t...
