Description

Technical Field

[0001] This invention relates to the field of smart elderly care and health monitoring technology, specifically to a home fall detection and emergency response device that integrates multimodal features. Background Technology

[0002] Home-based elderly care has become the mainstream model for elder care. In home settings, falls often occur during unattended periods such as getting up at night or washing up alone. If a fall occurs and rescue is not received promptly, it can not only worsen physical injuries but also easily lead to various complications. Therefore, developing reliable fall detection and emergency response technologies for elderly people living at home has become an urgent need to meet the basic needs of elder care. Areas for improvement in the use of home fall detection and emergency response devices include: When using home fall detection and emergency response devices, under normal circumstances, the fall prevention assistive device for the elderly can automatically detect falls and remotely alert the user. It also monitors and collects data on the elderly person's dynamic and static balance abilities, classifying and analyzing the data to determine the degree and type of balance impairment, facilitating emergency response. However, when using the home fall detection and emergency response device, the fall detection belt is worn by the user. Because the belt size is not adjustable, it cannot fit snugly against the user's waist, preventing the detection components on the waist from accurately monitoring the severity of the fall. Furthermore, since only one or two detection components are installed on the waist, it can only simply detect whether the user has fallen, without determining the degree and type of injury. Consequently, the sensors cannot issue different alarms based on the severity of the fall, potentially leading to delayed detection and rescue, which could endanger life and miss the optimal time for treatment. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention is achieved through the following technical solution: a home fall detection and emergency response device with multimodal feature cascade fusion, the structure of which includes a processor, a monitoring device, a Velcro layer, and a Velcro adhesive layer. The processor is installed in the middle of the monitoring device, and the rear ends of the monitoring device are respectively provided with Velcro layers and Velcro adhesive layers connected thereto, the Velcro layers being bonded to the Velcro adhesive layers.

[0004] As a further optimization of the invention, the monitoring device includes a detection component, a fitting pad, and a waist belt. The detection component comprises four or more components, which are equidistantly and laterally installed on the left and right sides of the waist belt. The waist belt is fitted with a fitting pad, which is connected to the detection component.

[0005] As a further optimization of the invention, the detection component includes a reset spring, a support plate, a conductive component, a fall sensing component, and a base. There are two reset springs, which are connected between the support plate and the base. Fall sensing components are symmetrically installed on both sides of the top of the base, and the ends of the two fall sensing components away from the base are inserted into the lower sides of the support plate. A conductive component is installed on the top of the support plate.

[0006] As a further optimization of the invention, the user wears the waist trainer around their waist using a Velcro layer and a Velcro adhesive layer. The processor and monitoring device are then electrically connected, and multiple detection components on the waist trainer are attached to the user's waist. The conductive components on the detection components are then connected to the user's waist. When the user falls, the conductive components and two fall sensing components work together to sense the fall. The two components work together to transmit the fall pressure value to the processor. The processor's internal processing unit performs priority judgment and parallel processing, thereby activating different response mechanisms for different degrees of fall.

[0007] As a further optimization of the invention, the processor is equipped with a communication module, a buzzer, and a camera. The pressure sensor inside the monitoring device transmits the sensed data to the processor to calculate a dynamic confidence score in real time. Then, the internal communication module, buzzer, and camera work together to play an emergency response role.

[0008] As a further optimization of the invention, the waist belt is equipped with a processor, which is electrically connected to multiple detection components inside it. The information detected by the multiple detection components is transmitted to the processor for processing.

[0009] As a further optimization of the invention, the base is installed inside the waist belt, and the transmission component will fit against the inner side of the waist belt. Two return springs, together with the support plate, support the transmission component, so that the transmission component can fit snugly against the user's waist.

[0010] As a further optimization of the invention, the conductive assembly includes a sensing element, a flexible patch, and a support pad. The sensing element is provided in multiples, and the multiple sensing elements are arranged in a ring at equal intervals inside the flexible patch, and the flexible patch fits and adheres to the middle position of the support pad.

[0011] As a further optimization of the invention, the support pad is fitted and connected above the support plate, and the soft patch will adhere to the user's waist in conjunction with the sensing element. The soft patch has the adsorption effect of a suction cup, so that the sensing element can be stably connected to the user's body under its action.

[0012] As a further optimization of the invention, the fall sensing component includes a sensor, a pressure plate, a linkage component, a connecting rod, a housing, and a snap-fit ​​plate. Multiple sensors are provided and arranged equidistantly and parallelly at the bottom of the housing. A pressure plate is located above the housing, and a connecting rod is vertically inserted into the top of the pressure plate. The connecting rod extends vertically into the housing. A snap-fit ​​plate is located at the lower end of the housing and is fixedly connected to the pressure plate. Linkage components are located on the lower ends of both sides of the snap-fit ​​plate, and the lower ends of two linkage components are connected to the lower sides of the housing.

[0013] As a further optimization of the invention, the housing is fixed on the base, and the upper end of the connecting rod is fixedly inserted into the lower end of the support plate. The support plate is subjected to force through the transmission component and transmitted to the connecting rod. The connecting rod will then drive the pressure plate to move downward and press the sensor. At the same time, the pressure plate will drive the two linkage components to move through the snap-fit ​​plate. Thus, the degree of fall can be monitored and sensed by the cooperation of the linkage components and the sensor.

[0014] As a further optimization of the invention, the linkage component is provided with a telescopic frame, a pressure rod, an extrusion guide, and a connecting spring plate. An extrusion guide is installed in the middle of the telescopic frame, and the end of the extrusion guide away from the telescopic frame is connected to the inner arc surface of the connecting spring plate. The pressure rod is vertically attached to the top of the connecting spring plate.

[0015] As a further optimization of the invention, the telescopic frame is installed at the lower end of the housing, and the pressure rod is inserted into the snap-fit ​​plate. The snap-fit ​​plate moves under the action of the pressure plate and simultaneously presses the pressure rod downward. The pressure rod will squeeze the extrusion guide through the connecting spring plate, and the extrusion guide will retract under the force.

[0016] As a further optimization of the invention, the extrusion guide is provided with a connector, a movable pressure member, a movable ring, and a sensing module. There are two connectors, which are symmetrically arranged at both ends of the upper line of the movable ring. There are two movable pressure members inside the movable ring, which are symmetrically arranged at the upper and lower ends inside the movable ring. The sensing module is fixedly connected to the left and right sides of the movable ring, and the sensing module is connected to the movable pressure member through the movable ring.

[0017] As a further optimization of the invention, the two connectors are respectively connected between the telescopic frame and the connecting spring plate. The force on the pressure rod will be transmitted to the movable ring through the connecting spring plate. The movable ring will retract inward due to the force, and the two moving pressure members inside it will collide with the sensing module. The sensing module can then sense the collision pressure. Beneficial effects

[0018] This invention discloses a home fall detection and emergency response device based on multimodal feature cascade fusion, which has the following beneficial effects: 1. This invention uses a Velcro layer and a Velcro adhesive layer to make the waist belt worn on the waist. The processor and monitoring device are electrically connected. The processor is equipped with a communication module, a buzzer, and a camera. The pressure sensor inside the monitoring device receives pressure data and transmits the sensed data to the processor to calculate a dynamic confidence score in real time. Then, the communication module, buzzer, and camera inside the device work together to play an emergency response role.

[0019] 2. This invention uses a conductive component that fits snugly against the user's waist. When the user falls, the conductive component on the side of the fall is compressed, and this pressure is transmitted downwards through the support plate to the two fall sensing components. This allows the conductive component and the two fall sensing components to work together to sense the fall pressure. The combined force transmits the pressure value to the processor. Multiple sensing elements are attached to the corresponding positions on the user's waist by the soft patch. When the user falls, the sensing element at the fall location is compressed and retracts inwards. The sensing element and the two fall sensing components then transmit the pressure to the processor. The processor's internal processing unit performs priority judgment and parallel processing, thereby activating different response mechanisms for different degrees of fall.

[0020] 3. In this invention, the housing is fixed to the base, and the upper end of the connecting rod is fixedly inserted into the lower end of the support plate. The support plate transmits force to the connecting rod through the transmission component. The connecting rod then drives the pressure plate to move downward and impact and press against multiple sensors at its lower end. The multiple sensors work together to sense the impact, and the pressure plate drives two linkage components to move through the snap-fit ​​plate. The sensing modules and sensors on the linkage components work together to transmit the pressure to the processor. The processor analyzes and processes the data sensed by the transmission components, thereby clarifying the degree and type of injury after the elderly person's fall and issuing alarms of different levels.

Detailed Implementation

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] Example 1 Please see Figures 1-4 , A multimodal feature cascade fusion home fall detection and emergency response device includes a processor 1, a monitoring device 2, a Velcro layer 3, and a Velcro adhesive layer 4. The processor 1 is installed in the middle of the monitoring device 2, and the Velcro layer 3 and the Velcro adhesive layer 4 are respectively provided at the two ends of the rear side of the monitoring device 2 and are connected thereto. The Velcro layer 3 and the Velcro adhesive layer 4 are bonded together.

[0030] The monitoring device 2 is provided with a detection component 21, a fitting pad 22, and a waist belt 23. The detection component 21 is provided with four or more components. The four or more detection components 21 are installed horizontally at equal intervals on the left and right sides of the waist belt 23. The fitting pad 22 is attached to the waist belt 23 and is connected to the detection component 21.

[0031] The detection component 21 includes a reset spring 211, a support plate 212, a conduction component 213, a fall sensing component 214, and a base 215. There are two reset springs 211, and the two reset springs 211 are connected between the support plate 212 and the base 215. The fall sensing components 214 are symmetrically installed on both sides of the top of the base 215, and the ends of the two fall sensing components 214 away from the base 215 are inserted into the lower sides of the support plate 212. The conduction component 213 is installed on the top of the support plate 212.

[0032] The user wears the waist trainer 23 around their waist using the Velcro layer 3 and Velcro adhesive layer 4. The processor 1 and the monitoring device 2 are then electrically connected. Multiple detection components 21 on the waist trainer 23 are then attached to the user's waist. The conduction components 213 on the detection components 21 are then connected to the user's waist. When the user falls, the conduction components 213 and two fall sensing components 214 work together to sense the fall and transmit the fall pressure value to the processor 1. The processor 1's internal processing components perform priority judgment and parallel processing, thereby activating different response mechanisms for different degrees of fall.

[0033] The processor 1 is equipped with a communication module, a buzzer, and a camera. The pressure sensor inside the monitoring device 2 transmits the sensed data to the processor 1 to calculate a dynamic confidence score in real time. Then, the communication module, buzzer, and camera inside the processor work together to play an emergency response role.

[0034] The waist belt 23 is equipped with a processor 1, which is electrically connected to multiple detection components 21 inside it. The information detected by the multiple detection components 21 is transmitted to the processor 1 for processing.

[0035] The base 215 is installed inside the waist belt 23, and the transmission component 213 will fit against the inner side of the waist belt 23. Two return springs 211, together with the support plate 212, support the transmission component 213, so that the transmission component 213 can fit tightly against the user's waist.

[0036] The conductive assembly 213 is provided with a sensing element 2131, a flexible patch 2132, and a support pad 2133. There are multiple sensing elements 2131, which are arranged in a ring at equal intervals inside the flexible patch 2132, and the flexible patch 2132 fits and adheres to the middle position of the support pad 2133.

[0037] The support pad 2133 is connected to the support plate 212. The soft patch 2132 will be attached to the user's waist in conjunction with the sensing element 2131. The soft patch 2132 has the adsorption effect of a suction cup, so that the sensing element 2131 can be stably connected to the user's body under its action.

[0038] This invention provides a home fall detection and emergency response device based on multimodal feature cascade fusion. The working principle of the above technical solution is explained below: In use, the user wears the waist trainer 23 around the waist using the Velcro layer 3 and Velcro adhesive layer 4. The processor 1 and monitoring device 2 are electrically connected. The processor 1 contains a communication module, a buzzer, and a camera. The pressure sensor inside the monitoring device 2 receives pressure data and transmits it to the processor 1 for real-time calculation of a dynamic confidence score. The communication module, buzzer, and camera work together to provide an emergency response. Multiple detection components 21 on the waist trainer 23 are then attached to the user's waist, and a [missing information - likely a device name or component] is attached to the inner wall of the waist trainer 23. A layered pad 22 adheres to the user's skin, effectively providing protection and breathability. Multiple detection components 21 are electrically connected to the processor 1 for conduction. The conduction components 213 on the detection components 21 then fit snugly against the user's waist. A base 215 is installed inside the waist belt 23, and the conduction components 213 adhere to the inner side of the waist belt 23. Two return springs 211, in conjunction with a support plate 212, support the conduction components 213, ensuring they fit snugly against the user's waist. When the user falls, the conduction component 213 on the side where the fall occurred is compressed, and this pressure is transmitted downwards through the support plate 212. The force is directed to two fall-sensing components 214, allowing the transmission component 213 and the two fall-sensing components 214 to work together to sense the impact of the fall. The two components work together to transmit the fall pressure value to the processor 1. The support pad 2133 on the transmission component 213 is fitted onto the support plate 212. The soft patch 2132, along with the sensing element 2131, is attached to the user's waist. The soft patch 2132 has a suction cup effect, allowing the sensing element 2131 to be stably attached to the user's body. Multiple sensing elements 2131 are attached to corresponding positions on the user's waist. When the user falls, the sensing element 2131 at the point of fall will... As the pressure is applied and the sensor retracts inward, the sensing element 2131 and the two fall sensing components 214 transmit the pressure to the processor 1. The processor 1's internal processing components perform priority judgment and parallel processing, thereby enabling different response mechanisms to be activated for different degrees of fall. The processor 1 calculates confidence scores for each sensor in real time, and its internal system can intelligently adjust the sensor dependency priority according to the scenario, such as increasing the weight of radar and audio sensors at night and strengthening the role of the inertial measurement unit in private areas. At the same time, it integrates the preliminary judgment of each sensor with the optimal dynamic confidence score to output accurate detection results, thereby accurately monitoring the degree of the user's fall.

[0039] Example 2 Please see Figures 5-7 , The fall sensing component 214 includes a sensor 2141, a pressure plate 2142, a linkage component 2143, a connecting rod 2144, a housing 2145, and a snap-fit ​​plate 2146. Multiple sensors 2141 are arranged equidistantly and parallelly at the bottom of the housing 2145. A pressure plate 2142 is located above the housing 2145, and a connecting rod 2144 is vertically inserted into the top of the pressure plate 2142. The connecting rod 2144 extends vertically into the interior of the housing 2145. A snap-fit ​​plate 2146 is located at the lower end of the housing 2145. The snap-fit ​​plate 2146 is fixedly connected to the pressure plate 2142. Linkage components 2143 are located on the lower ends of both sides of the snap-fit ​​plate 2146, and the lower ends of two linkage components 2143 are connected to the lower sides of the housing 2145.

[0040] The housing 2145 is fixed on the base 215. The upper end of the connecting rod 2144 is fixedly inserted into the lower end of the support plate 212. The support plate 212 is subjected to force through the transmission component 213 and transmitted to the connecting rod 2144. The connecting rod 2144 will drive the pressure plate 2142 to move downward and press the sensor 2141. At the same time, the pressure plate 2142 will drive the two linkage components 2143 to move through the snap-fit ​​plate 2146. Thus, the degree of fall can be monitored and sensed by the cooperation of the linkage components 2143 and the sensor 2141.

[0041] The linkage component 2143 is provided with a telescopic frame 1431, a pressure rod 1432, an extrusion guide 1433, and a connecting spring plate 1434. The extrusion guide 1433 is installed in the middle of the telescopic frame 1431, and the end of the extrusion guide 1433 away from the telescopic frame 1431 is connected to the inner arc surface of the connecting spring plate 1434. The pressure rod 1432 is vertically attached to the top of the connecting spring plate 1434.

[0042] The telescopic frame 1431 is installed at the lower end of the housing 2145. The pressure rod 1432 is inserted into the snap-fit ​​plate 2146. The snap-fit ​​plate 2146 moves under the action of the pressure plate 2142 and simultaneously presses the pressure rod 1432 downward. The pressure rod 1432 will press the extrusion guide 1433 through the connecting spring plate 1434. The extrusion guide 1433 will retract under the force.

[0043] The extrusion guide 1433 is provided with a connector 4331, a movable pressure member 4332, a movable ring 4333, and a sensing module 4334. There are two connectors 4331, which are symmetrically arranged at both ends of the upper part of the movable ring 4333. There are two movable pressure members 4332 inside the movable ring 4333, which are symmetrically arranged at the upper and lower ends inside the movable ring 4333. The sensing module 4334 is fixedly connected to the left and right sides of the movable ring 4333, and the sensing module 4334 is connected to the movable pressure member 4332 through the movable ring 4333.

[0044] The two connectors 4331 are respectively connected between the telescopic frame 1431 and the connecting spring plate 1434. The force on the pressure rod 1432 will be transmitted to the movable ring 4333 through the connecting spring plate 1434. The movable ring 4333 will retract inward due to the force, and the two moving pressure members 4332 inside it will collide with the sensing module 4334. The sensing module 4334 can sense the collision pressure.

[0045] This invention provides a home fall detection and emergency response device based on multimodal feature cascade fusion. The working principle of the above technical solution is explained below: In use, the housing 2145 is fixed to the base 215, and the upper end of the connecting rod 2144 is fixedly inserted into the lower end of the support plate 212. The support plate 212 transmits force to the connecting rod 2144 through the transmission component 213. The connecting rod 2144 then moves the pressure plate 2142 downward, impacting and pressing against multiple sensors 2141 at its lower end. The multiple sensors 2141 work together to sense the signals, and the pressure plate 2142 then drives two linkage groups through the snap-fit ​​plate 2146. When component 2143 moves, the pressure rod 1432 on the linkage component 2143 will be inserted into the snap-fit ​​plate 2146. After receiving the downward pushing force from the snap-fit ​​plate 2146, the pressure rod 1432 will press down on the connecting spring plate 1434. After being subjected to force, the connecting spring plate 1434 will move downward and expand outward to press the extrusion guide 1433 connected to its lower end. The two connectors 4331 on the extrusion guide 1433 are respectively connected between the telescopic frame 1431 and the connecting spring plate 1434. The force on the pressure rod 1432 is transmitted to the connector 4331 above it through the connecting spring plate 1434. The connector 4331 moves downward and squeezes the movable ring 4333. The movable ring 4333 retracts inward, and the two moving pressure pieces 4332 inside it are pressed together by the movable ring 4333. Their sides collide with the sensing module 4334. The sensing module 4334 can sense the collision pressure. The sensing module 4334 and the sensing element 2141 cooperate to transmit the pressure to the processor 1. The processor 1 analyzes and processes the data sensed by the transmission component 213. The processor 1 extracts multi-dimensional feature vectors in parallel from the pre-processed data through its internal components. This allows it to determine the degree and type of injury after the elderly person falls and issue different levels of alarms. This enables timely detection and rescue of the user, effectively protecting the user and avoiding life-threatening situations that could lead to missed opportunities for treatment.
