Problems solved by technology

[0004] The above-mentioned monitoring methods need to meet the conditions of falls more strictly to determine falls, and these conditions are often idealized, which are quite different from the actual conditions of falls, so the recognition rate is low, or it is easy to cause misjudgment due to the single recognition condition

Embodiment Construction

[0027] The fall monitoring and alarm method of this embodiment mainly includes continuously and simultaneously acquiring the acceleration data, body angle data and plantar pressure data of the human body; When the bottom pressure is less than the pressure threshold, an alarm is activated.

[0028] Compared with the traditional monitoring of a single element, this embodiment simultaneously monitors acceleration, body inclination and plantar pressure, which can increase the accuracy of fall judgment.

[0029] Further description will be made below in conjunction with the accompanying drawings.

[0030] Such as figure 1 As shown in the figure, it is a flow chart of a fall monitoring and alarm method of an embodiment. Including the following steps:

[0031] S110: Obtain the acceleration, body inclination and plantar pressure of the human body. Human body acceleration is decomposed into acceleration in three directions of x, y, and z. The three directions of x, y, and z include...

Abstract

The invention relates to a fall monitoring and warning method which comprises the following steps of: continuously acquiring at least two kinds of data in acceleration data, body angle data and plantar pressure data of a human body simultaneously; judging whether the acquired at least two kinds of data simultaneously meet the following corresponding conditions that: the acceleration is greater than a set acceleration threshold, the body angle is greater than a tilting angle threshold, and the plantar pressure is smaller than a pressure threshold; and if the conditions are met, starting to warm. The information acquired by a three-axis accelerometer, an attitude sensor and a pressure acquisition module is merged, the fall state can be judged more comprehensively, the accuracy degree of judgment is increased, and false judgment is reduced.

Description

【Technical field】 [0001] The invention relates to a monitoring device, in particular to a fall monitoring and alarming method and system. 【Background technique】 [0002] Accidental falls can happen in the life of the elderly or people with medical conditions. The bones of the elderly are relatively loose, and a simple fall may cause serious consequences, making them unable to save themselves; patients with coronary heart disease, cerebral infarction, cerebral hemorrhage and other diseases may fall into a coma. If the above people delay the timing of rescue, the consequences will be disastrous. When the above people have no accidents, they are the same as healthy people. It is impossible to be treated in the hospital for a long time. In addition, the pace of life in today's society is accelerating, and it is unrealistic for children or guardians to accompany them for a long time. [0003] There are many ways to monitor falls, such as by analyzing the acceleration, the angle...
