The present invention proposes a sleep time extraction method for home health monitoring radar, which uses the number of radar point clouds every 0.5 hours as an indicator of the activity of people in the space, and judges the time for people to get up and go to bed through logical reasoning. It includes the following steps: Step 1, the radar obtains the activity point cloud data of the human body in the scene, and the number of human activity point clouds is defined as the human activity at intervals of 0.5 hours to form an array of human activity for the day, and normalizes it by dividing it by the maximum human activity of the day to obtain 48 activity values ​​for one day; Step 2, compare the activity value of the current time period with the activity of the previous N time periods, and extract the time to get up; Step 3, compare the activity of the current time period with the activity of the following M time periods, and extract the time to go to bed.

The invention belongs to the technical field of biological extraction, particularly relates to a biological medicine extraction device, and aims to solve the problems that the sampling amount is inconvenient to control in the existing sampling process, and the sampling amount is too much or too little easily; in order to solve the problems that in the prior art, after extraction, solid and liquid need to be separated independently, and the workload is increased, according to the scheme, the device comprises a workbench, an extraction cylinder is fixedly arranged at the top of the workbench in a penetrating mode, a filter cylinder is fixedly arranged at the top of the extraction cylinder in a penetrating mode, and a bottom cover corresponding to the filter cylinder is arranged at the bottom of the extraction cylinder in a threaded mode; the bottom seal is used for sealing the bottom of the filter cartridge; through integrated design, automation of the whole process from automatic feeding, mashing, stirring and extracting of materials to sampling of liquid at different depths is achieved, the extraction efficiency and accuracy are remarkably improved, particularly, due to the design of the sampling mechanism, the liquid at different depths can be flexibly sampled, the requirement for accurate control in biological medicine extraction is met, and the application prospect is wide. And liquid can be driven to flow, so that the extraction effect is improved.
