[0023] Combined with the attached Figure 1 - Figure 2 , a multifunctional integrated intelligent anti-fall clothing. The anti-fall clothing includes a clothing body 1. Sleeves are provided on the clothing body 1. The sleeves include an upper arm part 5 fixedly connected to the sleeves and a forearm part 3 detachably connected to the upper arm part 5.

A lithium battery for powering the nine-axis sensor, the health detection armband 6, and the intelligent buttons 2 is also provided on the clothing body 1. The health detection armband 6 is arranged on the upper arm part 5. The health detection armband 6 includes an armband body. A PPG sensor and a temperature sensor are provided on the armband body. The health detection armband 6 is arranged on the upper arm part 5. The health detection armband 6 includes an armband body. A PPG sensor and a temperature sensor are provided on the armband body.

[0024] The present application uses a double-layer fabric. The inner layer uses a skin-friendly high-end pure cotton fabric with strong air permeability and good sweat absorption. The outer layer uses D30 with strong anti-impact performance and a graphene material fabric with wide antibacterial properties, which can effectively prevent the growth of bacteria and fungi, prevent allergies and asthma and other diseases of the elderly, and can also be washed without water, which is labor-saving, clean and hygienic.

[0025] The present application selects a lithium-ion battery with high energy density and long cycle life, and an LED flashing light is built in to remind the user to charge in time. When it works normally and the battery level is greater than 50, two green lights will flash; when the battery level is less than 50 and greater than 20, one green light will flash; when the battery level is lower than 20, one red light will flash and a prompt sound will be emitted to remind charging; when a fault occurs, two red lights will flash and a prompt sound will be emitted to remind inspection and maintenance.

[0026] In this application, the upper arm part 5 and the lower arm part are connected by a zipper, allowing the elderly to make choices according to their preferences or weather conditions.

[0027] In this application, the health detection armband 6 provides services for the elderly to monitor heart rate, blood oxygen and body temperature in real time.

[0028] In this application, an intelligent button 2 is set at the middle position of the collar, providing four major functions: positioning, emergency call, daily reminder and fast photo transmission. Children can also monitor the situation of the elderly through the camera at any time.

[0029] Combined Figure 4 As shown, this application is based on the acquisition and analysis of human body acceleration, and comprehensively uses various algorithms and technologies such as nine-axis sensors, threshold analysis, instantaneous speed calculation, and Coriolis effect to detect whether the elderly fall and whether an airbag needs to be ejected. The wearable sensing detection method is selected, which has the lowest price and the highest detection accuracy.

[0030] This application selects a nine-axis sensor to measure the inertial force generated by human body movement. By substituting this inertial force into Newton's second law, the acceleration generated during human body movement is obtained, which is mainly used for parameter acquisition during the elderly's fall process. Motion mode data in multiple dimensions are collected and connected to the control system.

[0031] The selected nine-axis sensor is composed of a capacitive three-axis accelerometer, a three-axis gyroscope and a magnetometer sensor. The capacitive three-axis accelerometer is composed of three independent MEMS for detecting the X-axis, Y-axis, and Z-axis. The acceleration data of the human body movement state collected is synthesized by two parts. One part is the acceleration generated by the human body's own movement, and the other part is the gravitational acceleration generated by the earth's gravity. And these two parts exist simultaneously from beginning to end. Therefore, data analysis and feature extraction can be carried out on the resultant acceleration generated by the fall action through the resultant acceleration composed of these two parts, and it is compared with the resultant acceleration under normal conditions to obtain one or more thresholds between falling and normal actions. If the resultant acceleration data signal received by the three-axis accelerometer exceeds the preset threshold, it is judged that a fall has occurred. However, in real life, it is difficult to judge whether the elderly have actually fallen only by acceleration, so data from other sensors in the nine-axis sensor is also needed for auxiliary judgment.

[0032] The three-axis gyroscope sensor is composed of three independent MEMS for detecting the X-axis, Y-axis, and Z-axis, and generates an angular rate according to the Coriolis force effect (the acceleration phenomenon generated by the linear velocity of each point of a moving object due to a rotating reference system being different). When an object moves linearly in the sensor coordinate system, a rotation is applied to the coordinate system. At this time, during the rotation process, the object will feel a radial velocity v1 and also a tangential velocity v2. The formula for the Coriolis force F is as follows:

[0033] F = 2mω·ν

[0034] Thus, the signals generated by the capacitive sensors on each axis are converted into voltages proportional to the angular velocity, so a gyroscope can be used to measure the angular velocity generated when a person falls.

[0035] A magnetometer sensor is an output device that converts a magnetic field and its change amount into an electrical signal.

[0036] As Figure 6 shown, a geographic coordinate system OXYZ is established, where O is the observation point, and X, Y, and Z point to the north, east, and local directions respectively. The northward projection component of the geomagnetic intensity T on the X-axis is T x , and the eastward projection component on the Y-axis is T y , so the projection component on the horizontal plane OXY is T xy ; the vertical projection component on the Z-axis is T z . α is the angle between the plane formed by the horizontal component T xy of the geomagnetic field and the vertical component T z and the geographic meridian plane OXZ, which is called the magnetic declination; β is the angle between the geomagnetic intensity T and the horizontal plane OXY, which is called the magnetic inclination. The above-mentioned geomagnetic intensity T, the projections on the north, east, and local axes are T x , T y , T z ; the projection T xy on the northeast plane, the magnetic course angle α and the magnetic declination β can be used to calculate the yaw angle, and the expressions between these 7 elements are as follows:

[0038]

[0039] The magnetometer sensor converts the detected magnetic signals into measurable signals, and then measures these measurable signals to predict whether a person has a tendency to fall and determine whether the person has fallen. During the fall process, by combining the resultant acceleration threshold provided by the capacitive triaxial acceleration sensor with the angular velocity of the human body during a fall generated by the triaxial gyroscope sensor, the human body posture at this time can be determined. Supplementary to this, the magnetometer is used to predict the yaw angle of the human body to determine whether the person has a tendency to fall, and then further determine whether the person has fallen, which is beneficial to reducing the judgment error. The nine-axis sensor realizes the fusion of data from three inertial devices through the complementary characteristics of acceleration, gyroscope, and magnetometer in the frequency domain, improving the accuracy and dynamic characteristics of attitude calculation, and more effectively detecting whether the elderly person has fallen.

[0040] When the nine-axis sensor detects that an elderly person is about to fall, it will emit a signal processed by a specific algorithm. The gas cylinder receives the signal and releases gas, triggering the inflation of the airbag 4 in the clothes and triggering an alarm. Moreover, after detecting a fall behavior, the airbag 4 can quickly open the airbag within 0.08 s to 0.09 s to play a protective role. Some scholars have measured the time of a simulated human fall through a high-speed dynamic recorder, and this process takes about 0.8 s. Therefore, the time for this application to open the airbag 4 is much less than the time required for a human fall, adding an "air cushion" at the moment when the elderly person's body touches the ground, focusing on protecting the face, chin, head, neck, chest, back, waist, hip, hip, and buttocks of the elderly, increasing the contact area between the elderly person's body and the ground, extending the force-bearing time, thereby achieving a buffering function and reducing the injuries suffered by the elderly in a fall accident.

[0041] Combined Figure 5 As shown, the health detection function of this application is based on the principle of photoplethysmogram signal and the contact temperature measurement method, providing real-time monitoring services for the elderly's heart rate, blood oxygen, and body temperature.

[0042] When light irradiates the human skin, the absorption of light by each subcutaneous tissue is different. After the light beam is absorbed and reflected by the human tissue, it is received by a photoelectric sensor. The received optical signal is converted into an electrical signal by the sensor, and this electrical signal is called a photoplethysmogram. Therefore, the PPG sensor can accurately measure the change in light transmittance in the body organs and tissues caused by the heartbeat to detect the heart rate and blood oxygen of the elderly.

[0043] A temperature sensor is set on the health detection armband 6. The contact temperature measurement method is adopted, and the accurate measurement of the elderly's body temperature is realized through a negative temperature coefficient thermistor, that is, an NTC thermistor. It acts as a wearable and portable intelligent thermometer, and its data and analysis results can be transmitted to the designated APP in time through the Bluetooth module, and reasonable suggestions are put forward for the elderly.

[0044] Combined with Figure 3 , the intelligent button 2 provides positioning, emergency call, daily reminder and photo fast transmission services for the elderly. The intelligent button 2 adopts a Beidou plus GPS dual positioning system, which is convenient for children to remotely view the positioning and keep track of the elderly's location information at any time. A one-key for help function is designed for the elderly. Through the nine-axis sensor and the health detection armband 6, the physical condition of the elderly is detected. When an emergency is detected, the intelligent button 2 will automatically trigger the dialing program, send a distress signal to the previously set emergency contact, and call the 120 emergency call through the AT command (using the Arduino processor). After the call is connected, a pre-recorded distress message will be played, such as "This is a certain device, an emergency has been detected, please immediately dispatch an ambulance", and the location information will be sent to the children and the emergency center via text message.

[0045] At the same time, the intelligent button 2 can also connect to the network. Through the positioning module and RTC module in the designated APP, arrival reminder, medication reminder and meal reminder are set. Through intelligent voice broadcast, it helps the elderly travel more safely, take medicine in time and eat on time. If the elderly do not get off the bus, take medicine or eat on time, the micro camera on the intelligent button 2 can use the Wi-Fi Direct technology to send photos of its surrounding environment to the children without an external network.

[0046] Through the Internet of Things technology in this application, the nine-axis sensor, the health detection armband 6 and the intelligent button 2 can communicate with each other, share data and perform remote control, improving efficiency, reducing costs and optimizing resource utilization, making it more automated, intelligent and suitable for the elderly.

[0047] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown throughout the text is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design a structural manner and an embodiment similar to the technical solution without creative work without departing from the creative purpose of the present utility model, they shall fall within the protection scope of the present utility model.
