In this embodiment, please refer to fig. 5, when the millimeter wave radar module 20 in the monitoring device body 1 transmits a millimeter wave electromagnetic signal to the human body in the learning area, an echo signal reflected by the human body is received, the echo signal is complex data including amplitude information and phase information, not only includes the radial distance and radial velocity information of the human body target, but also includes abundant micro-motion information of each part of the body, such as an arm, and the micro-motion information can help the radar to distinguish the motion state of the human body target and extract parameters well, so that the data amount required to be processed is large if all the learning state monitoring analysis is performed, which results in too high monitoring power consumption and low efficiency, in this embodiment, the position of the human body is first located according to the echo signal, because the millimeter wave radar signal has poor penetrability to the human body and the echo amplitude is high, and the distance corresponding to the echo can be calculated according to the received echo time difference, so that the maximum amplitude value is found in the complex array of the echo signal, the distance corresponding to the maximum amplitude value is the distance between the human body and the monitoring device body 1, the maximum amplitude area is determined according to the width of the waveform of the maximum amplitude value, the distance range corresponding to the maximum amplitude area is the human body learning activity area, the target echo data corresponding to the maximum amplitude area is extracted from the echo signal, and the learning posture and writing state analysis is carried out through the target echo data, so that the processing efficiency of data processing is greatly reduced, and the high-efficiency real-time learning state monitoring is more favorably realized.
