Abstract

The invention discloses a man-machine interaction method based on a millimeter wave radar. The method comprises the following steps of: (1) performing initialization through a main control module, performing parameter setting on a millimeter wave radar module, a data processing module and an intelligent identification module, and sending a working instruction to the millimeter wave radar module; (2) transmitting linear frequency modulation continuous waves to a target scene by the millimeter wave radar module, collecting echo signals reflected by a target object to a script module through a receiving antenna, performing frequency mixing with transmitted signals to obtain intermediate frequency signals, and transmitting the intermediate frequency signals to the data processing module; (3) executing a resolving algorithm by the data processing module to obtain feature data, and transmitting the feature data to the intelligent identification module; (4) analyzing corresponding actions andinstructions by the intelligent identification module according to the feature data, and feeding back the corresponding actions and instructions to the main control module; and (5) issuing a controlinstruction by the main control module according to the feedback, and driving equipment to complete corresponding control actions. According to the man-machine interaction method disclosed by the invention, smart home equipment is expanded to perform interaction, so that the smart home equipment can feed back action posture instructions, and specific control operations can be realized according tomodel comparison.
