Alarm switch control device and method by extracting organism information by using biological radar

The invention, which belongs to the technical field of non-contact extraction and utilization of biological information, discloses an alarm switch control device and method by extracting organism information by using a biological radar. Breathing and heartbeat waveforms of organisms that are extracted and restored by a biological radar simultaneously are detected respectively; according to the detection result, various logic combined levels are provided as alarm level outputs; and a user selects a corresponding logic level based on the need to drive an alarm switch to work. Since the vital signs of the organisms are detected by the biological radar to control the switch, the monitored object does not need to make any sound or move and is not affected by the use environment temperature andthe heat generating object; and because the biological radar wave can effectively penetrate various media including various non-metallic items such as rain, fog, clothing, paper, plastic, etc,, problems of detection switch fa
