Description

Technical Field

[0001] The present invention belongs to the technical field of smart shoes, and in particular relates to a method and system for determining fall injury. Background Art

[0002] Falling is extremely harmful to the human body, especially for the elderly, and can even be life-threatening. Slippery shoes, steep ground, slippery ground, loose ground, potholes, or ground obstacles are important causes of falling. In the existing technology for detecting the risk of falling, once a person is detected to be at risk of falling, an alarm is issued, without considering the different levels of injury suffered by people in different fall scenarios, and it cannot accurately and effectively remind the parties or related personnel, increasing the safety risks of people.

[0003] Current technologies related to fall risk detection, such as the Chinese patent "A fall warning and protection system and method based on insole pressure sensing" with publication number CN112185063A, proposes to include multiple flexible pressure sensors, a Bluetooth transmitter and a first single-chip processor arranged on the insole, and a protective suit worn on the patient, on which an alarm button, a buzzer, a Bluetooth receiver, a second single-chip processor, and an airbag are arranged. The multiple flexible pressure sensors are electrically connected to the first single-chip processor, the first single-chip processor is electrically connected to the Bluetooth transmitter, the alarm button and the Bluetooth receiver are both electrically connected to the second single-chip processor, the output end of the second single-chip processor is electrically connected to the buzzer, the Bluetooth receiver, and the airbag, and the Bluetooth transmitter and the Bluetooth receiver are wirelessly connected. The Chinese patent "A fall monitoring device for the elderly and a fall risk assessment method" with publication number CN106887115B proposes a fall and fall-causing action recognition model based on plantar pressure data: a hidden Markov model of continuous variables is used to model the pressure change law of different collection parts, and flexible array pressure sensors are set at the heel, big toe, first metatarsal toe, and fourth metatarsal toe. The physical meaning of the pressure at each point is the dynamic state of a single foot, and the possible values ​​are initial contact, forward push, backward push, and air. Through training, the conditional probability and state transition probability matrix A of different pressure sensing points in different states are obtained, and the dynamic state of the single foot at the current moment is judged from this, and then the biomechanical characteristics of the alternating states of both feet are used to infer whether a fall action has occurred.

[0004] The above technical solution is a technology for assessing the risk of falling based on the matching of plantar pressure and the fall model. However, the above solution cannot effectively analyze the damage caused by falling according to the ground conditions, traffic conditions and movement speed of the person at the current location when a fall risk is detected, nor can it perform different treatments according to the different injuries caused by falling. At present, there is no technical solution that can effectively analyze the damage caused by falling according to the ground conditions, traffic conditions and movement speed of the person at the current location when a fall risk is detected. For this purpose, a fall injury determination method and system are proposed. Summary of the invention

A method for determining fall injury, characterized in that: include: Calculate the terrain damage assessment value when falling based on the ground information of the location area; The method of calculating the terrain damage assessment value when falling according to the ground information of the location area includes: calculating the ground terrain damage assessment value according to the relationship between the ground slope and / or the ground curvature and / or the ground step gradient and / or the degree of ground potholes within a certain range nearby and the damage caused when falling; calculating the ground obstacle damage assessment value according to the relationship between the number of obstacles and / or the connection firmness of obstacles and / or the depth of accumulated water within a certain range nearby and the damage caused when falling; calculating the terrain damage assessment value when falling according to the ground terrain damage assessment value and / or the ground obstacle damage assessment value; Calculating a traffic injury assessment value when falling based on traffic information in the location area; the calculation of the traffic injury assessment value when falling based on traffic information in the location area includes: calculating a traffic congestion injury assessment value based on motor vehicle flow and / or non-motor vehicle flow and / or crowd density within a certain range nearby; calculating an accident injury potential value based on the relationship between the distance information between the location and the motor vehicle lane and / or the distance between the location and the non-motor vehicle lane and the probability of an accident occurring when falling; calculating a traffic injury assessment value when falling based on the traffic congestion injury assessment value and / or the accident injury potential value; Calculating a speed injury assessment value when falling according to the action speed information; the calculation of the speed injury assessment value when falling according to the action speed information includes: calculating a speed mutation injury assessment value according to the relationship between the degree to which the current action speed exceeds the average speed in the previous period of time and / or the degree to which the current action speed exceeds the action speed in the previous sampling moment and the injury suffered when falling; calculating a damage assessment value when the action speed does not match the action state according to the relationship between the degree to which the current action speed exceeds the average speed when in a walking state and / or the degree to which the current action speed exceeds the average speed when in a running state and the injury suffered when falling; calculating a damage assessment value when the action speed does not match the surrounding state according to the relationship between the degree to which the current action speed exceeds the historical average action speed of the current position and / or the difference between the current action speed and the surrounding average action speed and the injury suffered when falling; calculating the speed injury assessment value when falling according to the speed mutation injury assessment value and / or the injury assessment value when the action speed does not match the action state and / or the injury assessment value when the action speed does not match the surrounding state; The damage assessment value is calculated based on the terrain damage assessment value at the time of the fall, the traffic damage assessment value at the time of the fall, and the speed damage assessment value at the time of the fall, and is used to determine the damage suffered when the fall occurs.

2. A fall injury determination system, characterized in that include: The shoe body and the fall injury determination device and data acquisition device installed in the shoe; The data acquisition device is used to obtain terrain information, traffic information and movement speed information of the location area; The fall injury determination device is used to determine the injury level incurred when falling, and includes: processor; Memory; and one or more programs; the one or more programs are stored in the memory and configured to be executed by the processor, the programs causing the computer to perform the method as claimed in claim 1.
