Embodiment Construction

[0026] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0027] This embodiment includes two pressure sensing belts composed of a plurality of pressure sensors, which are respectively used to sense the pressure values ​​generated by the user's back shoulders and buttocks. Place two rows of pressure sensors in parallel in each sensing zone, the two rows of pressure sensors are misplaced, and the vertical distance between the parallel lines formed by the two rows of pressure sensors is 5-10 cm, such as figure 1 shown. All pressure sensors are fixed on the flexible base, and each row of pressure sensors extends from one end of the flexible base to the other end, and the distance between the sensors is 8-15 cm, such as figure 2 shown. On the basis of ensuring the density of sensors in the sensing area, this deployment scheme increases the collection range of longitudinal sensors and reduces the problem of data collectio...

Abstract

The invention relates to a device of completing sleep position detection in non-perceiving state. The device is characterized by comprising a plurality of pressure sensors, an analog to digital converter and a data processor, wherein the plurality of pressure sensors form two pressure sensing bands which are arranged on a flexible base in parallel, and the space between the pressure sensing bands is equal to the distance between the tested shoulder and the buttock; the pressure sensing bands are pressure sensors with two rows of parallel lines with the vertical distance being 5-10 cm; the distance between the pressure sensors in each row is 8-15 cm; and two rows of pressure sensors are arranged in a staggered manner. Compared with other inventions, the device has the key point of arrangement of the pressure sensors and the sleep position judging method. The device has loose requirement on the sleep position of a user, and has high sleep detection accuracy.

Description

technical field [0001] The invention relates to the fields of information technology and health aids, in particular to a device and method for detecting sleeping postures in a non-aware state. Background technique [0002] Ubiquitous computing is human-centered computing, emphasizing the use of smart devices to provide services for people while reducing human participation as much as possible. Human behavior detection technology in smart homes has become a research hotspot in the field of ubiquitous computing. [0003] People spend one-third of their life in sleep, and poor sleep quality will cause serious damage to people's mental and physical health. With the development of various physiological detection technologies, sleep quality detection has also moved from a professional organization for sleep diagnosis to a daily health care behavior in a home environment. During sleep, the longer the body maintains a fixed posture and position, the deeper the sleep depth. On the c...
