Problems solved by technology

[0004] In the medical field, the electrocardiographic sensing device obtains various forms of potential changes from the surface body to obtain an electrocardiogram, thereby accurately obtaining information such as heart rate and respiration in real time, but requires the patient to adhere to multiple electrodes, which affects its normal activities, and it is very difficult for medical staff to operate. Complicated, the detection cost that the patient needs to bear is expensive, and the patient's physical and psychological load is relatively large; in the field of smart home, many existing monitoring devices need to arrange various sensors to obtain various sleep physiological signals separately, the cost is high, and the operation is complicated , affect sleep, and most of the devices are offline monitoring, which cannot realize real-time and visual monitoring

Abstract

The invention provides a pillow-type sleep monitoring apparatus and a sleep monitoring method based on a piezoelectric ceramic sensor. The sleep monitoring apparatus comprises a sleep signal acquisition device, a data interface, a signal processing device, a micro controller and terminal equipment which are sequentially connected by virtue of connecting wires; the sleep monitoring apparatus is characterized in that the sleep signal acquisition device comprises a main body, wherein a space is kept in the main body for holding the piezoelectric ceramic sensor; the piezoelectric ceramic sensor is connected to the data interface by virtue of a transmission lead; and the data transmission device is connected to the terminal equipment by virtue of a USB interface. According to the sleep monitoring apparatus and the sleep monitoring method provided by the invention, tiny pressure change in a human body under a natural sleep state can be sensed, so that such physiological statuses as heart rate, breathing, body motion and the like of the human body in sleep can be monitored in real time; the sleep monitoring apparatus and the sleep monitoring method are good in monitoring effect, high in accuracy rate, low in cost and low in load, and by analyzing sleep data, health assisting service can be provided to users; and the sleep monitoring apparatus and the sleep monitoring method and applicable to long-term monitoring and nursing in common families.

Description

technical field [0001] The invention belongs to the field of intelligent health perception, and in particular relates to a sleep monitoring device and method based on piezoelectric ceramic sensors. Background technique [0002] At present, the society is in the trend of rapid aging of the population structure. The physical and mental health of the elderly is gradually weakening, which will bring obstacles to their daily life. In severe cases, they may even lose their ability to take care of themselves. Expansion has become an inevitable trend. [0003] Studies have found that with age, the sleep quality of the elderly declines, which can induce various chronic diseases, and one-third of people's time is spent in sleep. Sensing the physiological state of the human body in this way is of great significance for the early detection and prediction of related cardiovascular and cerebrovascular diseases. [0004] In the medical field, the electrocardiographic sensing device obtai...
