An autonomous control system for mattress hardness distribution

technical field

The invention relates to a smart home, in particular to a smart mattress.

Background technique

The comfort of mattresses directly affects people's sleep health. With the improvement of modern living standards and the enhancement of health awareness, people have higher and higher requirements for the comfort of mattresses. Different people have different requirements for mattress parameters due to differences in age and body shape. There are mattresses of various materials and structures on the market, including springs, memory foam, latex, brown pads, etc. Although they can be used to a certain extent. It is close to the needs of different groups, but due to the complexity of the sleeping posture of the human body, it is still unable to effectively meet the individual needs of individuals, and the cost of customizing mattresses according to individual differences is too high. For example, the Chinese invention patent with the application date of 2018-01-08 and the application publication number of CN108013647A discloses "a smart mattress". The smart mattress disclosed in the patent is composed of an elastic cushion body, and its technical solution is to automatically adjust the elastic The high and low positions of the components make it fit the natural physiological curve of the human body, and effectively support the muscles of the waist and neck bending parts, so that the spine can relax naturally and achieve the best sleep state. However, this patent also has the aforementioned problems. Although the pressure distribution can be controlled by automatically adjusting the elastic components to control the support degree of each part of the mattress, so that the pressure on each part of the person is as uniform as possible. However, the real-time pressure of the mattress is passed through the bed. It is monitored by the pressure sensor on the pad. Since the degree of contact between the human body and the mattress at each position is different, and there is a shear force component in the force exerted by the human skin on the sensor, the pressure monitoring has a large error and cannot be truly responded. Distribution of human stress. In addition, the uniform distribution of human pressure is not an optimal strategy. The model is too simple and crude. Due to the differences in the body shape and physique of each individual, the optimal distribution of human pressure needs to comprehensively consider the shape of the human spine, underlying diseases, body defects, and the sensitivity of various parts. degree and many other factors, however, these factors contribute to the complexity and difficulty of the mattress pressure control problem.

To solve this problem, the system has added a feedback control function. Sleep pattern corrections are made based on previous data to maintain optimal comfort levels. The mattress may enter a dormant state when the sleeper leaves the mattress during sleep.

Since the previous data of the human body structure can be used to correct the sleep pattern, there are differences in the body shape and physique of each individual. The optimal distribution of human pressure needs to comprehensively consider the shape of the human spine, underlying diseases, physical defects, and the sensitivity of each part. All factors can be adjusted and corrected adaptively, so that the sleeper can fall asleep in a satisfactory and comfortable hardness distribution state.
