Problems solved by technology

[0004] Therefore, by measuring the change of the bandage and the air pressure detection result of the nasal cannula, medical personnel can check the breathing of the user during sleep. On the body, the user cannot move the body arbitrarily, which naturally causes the user's discomfort and pressure, causes the user's troubles, and interferes with the measurement results; and for the polysomnography analyzer (PSG), based on hygiene issues, the nasal cannula Is a consumable, thereby increasing the cost of testing

Abstract

A projected capacitive human motion detection system, comprising a sensing pad and a monitoring module, the sensing pad includes at least one sensing array unit and at least one control unit, the sensing array unit includes a plurality of sensing electrodes arranged in an array , the control unit is electrically connected to the sensing electrodes to periodically perform analog-to-digital conversion on the capacitance sensing values ​​detected from the sensing electrodes to generate a plurality of capacitance sensing values, and the plurality of capacitance sensing values The binarization operation is performed separately to obtain the binarization operation results of each capacitance sensing value; the monitoring module receives and displays the plurality of capacitance sensing values ​​and the binarization operation results as a reference for judging human body movements.

Description

technical field [0001] The invention relates to a human body motion detection system, in particular to a projected capacitive human body motion detection system. Background technique [0002] Polysomnogram (PSG) is an instrument used to record the user's sleep status, which can detect the user's brain activity, eyeball activity, muscle activity, breathing condition, heartbeat frequency and other information during sleep, for Medical personnel diagnose the user's sleep quality, and respiratory status is one of the important evaluation indicators. [0003] When detecting the breathing condition of the user through the polysomnia analyzer (PSG), the user is made to lie flat on a bed, and a stretchable elastic strap is used to tie the user's chest cavity, and the strap is equipped with a There is a detector. When the user inhales, the chest cavity expands to increase the body circumference due to the inhalation of air, and then the strap can be lengthened. The detection resul...
