Problems solved by technology

If the welfare home or nursing home cannot timely understand the accidents of the elderly outdoors, especially the accidental fall, they will not be able to treat the elderly in time, or endanger their lives.
[0003] In the prior art, auxiliary tools such as mobile phones are generally used for fall monitoring. However, auxiliary tools are not necessary for the elderly to go out, and they are troublesome to wear, and false alarms are prone to occur when the detection situation is complicated.

Embodiment 1

[0089] Obtain the temperature of the two smart shoes, which are the first temperature and the second temperature;

[0090] Judging whether the first temperature and the second temperature are not within the temperature range of the preset shoe-wearing state; if so, the smart shoe is in the idle state; otherwise, the smart shoe is in the use state;

[0091] If the state of the smart shoes is in use, then obtain the accelerations of the two smart shoes in the X-axis, Y-axis and Z-axis directions within a preset time to obtain a first acceleration set;

[0092] calculating the rate of change of each acceleration in the first set of accelerations within a preset time to obtain a second set of rates of change;

[0093] Analyzing the second set of rate of change, if each rate of change in the second set of rate of change is within the range of rate of change in a preset normal walking state, then each acceleration in the first set of accelerations is not abnormal, A person wearing ...

Embodiment 2

[0103] In a family A using smart shoes, the system automatically detects the temperature of the smart shoes (once every 2-3 minutes). If the temperature T1 detected by the temperature sensor inside the smart shoes is lower than the room temperature of 26°C or higher The temperature inside the shoes when wearing shoes (take the general normal situation: 45°C), it means that the smart shoes are not worn by the elderly, that is, the smart shoes are in an idle state. On the contrary, it means that the smart shoes are worn, and each corresponding module should enter the working detection state.

[0104] Assuming that the elderly M is detected to have worn smart shoes, the gyro sensor and acceleration sensor of the smart shoes will enter the working state. According to the transmitted acceleration data, analyze and judge through the controller, if Xa is basically at 1.5-2.2m / s^2 (acceleration of 2.2 meters per square second) (defined as X is the forward direction, Xa is the accelera...

Abstract

The invention aims to solve the technical problem of providing a state recognition method and a state recognition system based on intelligent shoes. The state recognition method and the state recognition system can recognize various states of a person wearing the intelligent shoes accurately, particularly an accidental falling state. The state recognition method comprises the steps of: recognizing states of the intelligent shoes through analyzing temperature of the intelligent shoes, wherein the state of the intelligent shoes include an idle state and a using state; and recognizing states of the person wearing the intelligent shoes through analyzing acceleration and tilt angles of intelligent shoes, wherein the recognition of the states of the person wearing the intelligent shoes includes the recognition of normal walking state, the recognition of non-falling abnormal motion state and the recognition of foot-lifting state and accidental falling state. Through analyzing the various states, the accuracy of accidental falling state recognition can be improved.

Description

technical field [0001] The invention relates to the field of intelligent monitoring, in particular to a state recognition method and system based on smart shoes. Background technique [0002] With the aging of our country, more and more elderly people will choose to live in institutions such as welfare homes or nursing homes. If the welfare home or nursing home cannot timely understand the accidents of the elderly outdoors, especially the accidental fall, they will not be able to treat the elderly in time, or endanger their lives. [0003] In the prior art, auxiliary tools such as mobile phones are generally used for fall monitoring. However, auxiliary tools are not necessary for the elderly to go out, and they are troublesome to wear, and false alarms are prone to occur when the detection situation is complicated. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a state recognition method and system based on sma...
