A state detection method, apparatus and device for an object relative to a bed

Abstract

Embodiments of the present invention relate to a method, device, and device for detecting a state of an object relative to a bed. The method includes: obtaining pressure information based on a pressure electrical signal detected by a pressure detection sensor; obtaining a digitized micro-motion sampling signal; combining the pressure information and the micro-motion sampling signal to determine a state of an object relative to the target bed, the object including a human body or an object. In the embodiment of the present invention, by combining the detection results of the pressure detection sensor and the micro-motion signal sensor to determine the state of the human body or the object relative to the target bed, it can be detected whether the human body is in a state of accidentally leaving the bed. Combining the two sensors for comprehensive judgment can avoid the misjudgment that the person is on the bed because the object is on the bed or that the person is off the bed because the person is not on the pressure sensor, and the detection accuracy is better.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of intelligent monitoring, and in particular, to a method, device, and device for detecting a state of an object relative to a bed. Background technique [0002] In the nursing of the elderly, monitoring whether the elderly leave the bed unexpectedly is an important aspect of nursing care for the elderly. The traditional monitoring method requires manpower to check at regular intervals, and the monitoring efficiency is very low. [0003] At present, there are some devices for monitoring the elderly's accidental departure from bed, which can use machines to automatically monitor whether the elderly are out of bed. misjudgment. SUMMARY OF THE INVENTION [0004] The purpose of the embodiments of the present invention is to provide a state detection method, device and device for an object relative to a bed with good monitoring accuracy, which can accurately determine whether a human body...
