[0002] With the aggravation of population aging and the increasing social concern about the quality of life of the elderly, intelligent fall monitoring devices have gradually become an indispensable safety guarantee tool in families and elderly care institutions.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. In this solution, by setting up a signal component, in the daily monitoring mode, the signal wave emitting head emits signal waves with low power to preliminarily monitor indoor personnel. This low-power mode not only extends the battery life of the device but also reduces unnecessary energy waste. When the signal component preliminarily determines that an indoor person may fall, it can quickly respond and automatically drive the beam component for secondary auxiliary determination through the data processor. During this process, the power of the signal wave emitting head will increase appropriately to cooperate with the beam component to achieve more accurate detection. This intelligent determination and response mechanism of the signal component not only improves the accuracy of fall monitoring but also ensures that the device can quickly and effectively play its role at critical moments;

[0017] 2. In this solution, by setting up a beam component, through structures such as an electric shaft rod, a mounting platform, a driving gear disk, an engaging ring plate, a horn antenna, etc., the beam component can achieve the beam collection and directional transmission of signal waves, thereby enhancing the intensity and penetration power of signal waves and achieving more accurate detection of the position of the suspected fallen person. After receiving the preliminary determination signal from the signal component, the beam component can quickly respond, rotate out from the storage groove through the rotation of the electric shaft rod, and be adjusted below the signal wave emitting head. Subsequently, the signal wave emitting head descends and is clamped and fixed with the horn antenna to complete the beam collection and directional transmission of signal waves. During this process, the beam component can not only improve the utilization rate of signal waves but also reduce the scattering and interference of signal waves, thereby improving the accuracy of fall monitoring;

[0018] 3. In this solution, by setting up auxiliary components, through the coordinated action of the cleaning component and the triggering component, the auxiliary component can achieve the cleaning and maintenance of key components inside the device, as well as the intelligent monitoring and adjustment of the working state of the device. The cleaning component, through structures such as the lifting motor, driving motor, and cleaning roller, can regularly wipe and clean key components such as the horn antenna, removing dust and dirt on the surface, thereby ensuring the smooth transmission of signal waves and the normal operation of the device. During this process, the wind generated by the fan blades can also accelerate the removal of dust and the cooling of components, further improving the operating efficiency and stability of the device. The triggering component, through structures such as the lifting plate body, signal driver, and electric telescopic rod, realizes the intelligent monitoring and adjustment of the working state of the device. When the device completes a monitoring task, the triggering component can automatically trigger the cleaning component to perform cleaning work, improving the operating efficiency and stability of the device.

Specific embodiments

[0030] Housing 1, an installation plate 2 is provided on the upper surface of the housing 1, a storage groove 18 is also opened on the bottom surface of the housing 1, ventilation openings 3 are opened on both side surfaces of the housing 1, a signal processing box 6 is provided on one side surface of the housing 1, a sound broadcasting port 7 and a display lamp 8 are provided on the surface of the signal processing box 6, a data processor is provided inside the signal processing box 6, a small fan 17 is also provided inside the housing 1, an air inlet 19 communicating with the small fan 17 is opened on the bottom surface of the housing 1, a detection mechanism is provided inside the housing 1, and the detection mechanism includes: a signal component and a beam component. The signal component includes: a lifting frame 12, the lifting frame 12 is provided on the inner bottom surface of the housing 1, a small motor is provided inside the lifting frame 12, a threaded rod is provided on the output end of the small motor, a limiting cross plate 46 is engaged on the surface of the threaded rod, a vertical sliding groove is also opened on the side surface of the housing 1 and is matched with the end of the limiting cross plate 46 departing from the lifting frame 12, a limiting circular hole is opened at the center of the limiting cross plate 46, a radar signal processor 9 is provided below the limiting cross plate 46, a limiting sphere 39 matched with the limiting circular hole is provided on the upper surface of the radar signal processor 9, a signal wave transmitting head 22 is provided on the bottom surface of the radar signal processor 9, a clamping convex ring 40 is sleeved on the surface of the signal wave transmitting head 22, a connecting cable 10 is also provided on the upper surface of the radar signal processor 9, the other end of the connecting cable 10 is connected to one side surface of the signal processing box 6, a wire hanging frame 11 matched with the connecting cable 10 is provided on the inner side surface of the housing 1, and a torsion spring is provided at the connection of the wire hanging frame 11 and the housing 1;

[0031] During use, the device is fixedly installed on the indoor ceiling through the installation plate 2. Under normal conditions, the beam component is stored below the storage groove 18 on the bottom surface of the housing 1. During daily detection, small-power signal waves are emitted through the signal wave transmitting head 22 for monitoring to monitor the indoor personnel. This small-power signal wave does not need to detect the precise state of the indoor personnel, but only serves as a preliminary detection and determination. If a person in the room has a fall, the user is assisted in detection through the induction component worn on the person's wrist. After the preliminary determination of a fall situation, the data processor inside the signal processing box 6 drives the beam component by itself. At this time, the signal wave transmitting head 22 also immediately increases the power of the signal wave, and cooperates with the beam component to more precisely detect the position of the suspected fallen person. In this way, during normal use, outside the time of a fall situation, the device can only emit small-power signal waves for monitoring, and when a suspected fall situation occurs, the power is increased for determination through the cooperation of other components, so as to reduce power consumption. If it is determined that a fall situation has occurred after detection, a message is sent to the mobile phone bound to the device through the data processor, and a reminder is given using the sound broadcasting port 7 and the display lamp 8 on the side surface of the signal processing box 6 to remind the people in other rooms, so that they can more quickly sense the fall situation and come to help the fallen person.

[0032] The beam-forming assembly includes: an electric shaft rod 34 disposed on the bottom surface of the housing 1. An installation platform 38 is provided on one side surface of the electric shaft rod 34. Limiting side rods 32 are provided on both sides of the installation platform 38. A limiting post 21 matching with the limiting side rod 32 is further provided on the bottom surface of the storage groove 18. A driving gear disk 33 is further provided on the upper surface of the installation platform 38. A braking motor for driving the driving gear disk 33 is further provided inside the installation platform 38. A rotatable meshing ring plate 37 is provided at the center of the installation platform 38. The meshing ring plate 37 meshes with the driving gear disk 33. A horn antenna 5 is provided below the meshing ring plate 37. A meshing ring groove 36 matching with the engaging convex ring 40 is formed on the upper surface of the horn antenna 5. Two connecting side plates 35 are provided on the upper surface of the horn antenna 5. An adjustment motor is provided between the connecting side plate 35 and the side surface of the meshing ring plate 37.

[0033] The beam-forming assembly is used for secondary auxiliary determination after the signal assembly initially determines that a fall situation has occurred. In the case of receiving double triggers from the signal assembly and the induction assembly, first, the small motor inside the lifting frame 12 starts to rotate. Through the meshing effect with the limiting cross plate 46, it drives the radar signal processor 9 to rise, so that the signal wave emitting head 22 also rises accordingly. Subsequently, the beam-forming assembly rotates through the electric shaft rod 34, flips out from the inside of the storage groove 18, and finally rotates below the signal wave emitting head 22. Subsequently, the small motor inside the lifting frame 12 rotates in the reverse direction, causing the signal wave emitting head 22 to descend. After descending to a certain distance, the engaging convex ring 40 on the surface of the signal wave emitting head 22 engages with the meshing ring groove 36 on the upper surface of the horn antenna 5. At this time, the signal wave emitting head 22 and the horn antenna 5 are fixed. Through the horn antenna 5, the signal wave emitted by the signal wave emitting head 22 can be beam-formed and transmitted in one direction. At this time, the signal wave emitting head 22 increases the output power again to strengthen the signal wave and perform more accurate detection on the specified position. After the signal wave emitting head 22 and the horn antenna 5 are fixed, the data processor provided inside the signal processing box 6 controls the driving gear disk 33 to rotate according to the induction of the position of the induction assembly worn on the wrist of the indoor personnel, so that the meshing ring plate 37 drives the horn antenna 5 and the signal wave emitting head 22 to rotate horizontally, and the adjustment motor vertically adjusts the signal wave emitting head 22 and the horn antenna 5, so that the horn antenna 5 can detect any position inside the room.

[0034] The detection mechanism further includes an auxiliary component, which includes a cleaning component and a triggering component. The cleaning component includes: two lifting motors 27, which are respectively arranged on the inner bottom surface of the housing 1. The end of the output shaft of the lifting motor 27 is provided with a force-bearing plate 26. A rotating plate body 15 is arranged between the two force-bearing plates 26. A rotating shaft is arranged at the connection between the rotating plate body 15 and the force-bearing plate 26. A driving motor 28 is arranged on the bottom surface of the rotating plate body 15. A connecting support rod 30 is arranged at the output end of the driving motor 28. A fan blade 29 is sleeved on the surface of the connecting support rod 30. A cleaning roller 31 is also arranged at the end of the connecting support rod 30. A main hook ring 23 is also arranged on the upper surface of the rotating plate body 15. A triggering ring button 20 that cooperates with the driving motor 28 is also arranged on the bottom surface of the storage groove 18. The triggering component includes: two lifting plate bodies 13. Lateral sliding grooves for the lifting plate bodies 13 to slide are respectively formed on the two inner side surfaces of the housing 1. A connecting spring 14 is arranged inside the lateral sliding groove. The bottom surface of the connecting spring 14 is connected to the upper surface of the lifting plate body 13. A signal driver 16 is also arranged on the inner side surface of the housing 1. Two engaging plates 44 are arranged on one side surface of the signal driver 16. An induction plate 45 is arranged at the end of the engaging plate 44. A triggering button is arranged on the bottom surface of the induction plate 45. An electric telescopic rod 25 is also arranged on one side surface of the signal driver 16. An auxiliary hook ring 24 that cooperates with the main hook ring 23 is arranged at the end of the output shaft of the electric telescopic rod 25;

[0035] The auxiliary component is used to provide auxiliary functions for the normal operation of the device. After a detection operation, the beam component is retracted to the bottom surface of the storage groove 18 again through the rotation of the electric shaft rod 34. The limiting side rod 32 cooperates with the limiting pile 21 to fix the position of the beam component. At this time, the bottom surface of the horn antenna 5 comes into contact with and triggers the trigger ring button 20. At this time, the two lifting motors 27 extend and retract, causing the force-bearing plate 26 to descend, causing the cleaning roller 31 to descend and enter the interior of the horn antenna 5. At this time, the drive motor 28 makes a primary drive, driving the cleaning roller 31 to wipe on the inner side surface of the horn antenna 5 to remove the dust on its surface, so that the horn antenna 5 will not affect the normal signal wave transmission work due to the dust on its surface. When the connecting support rod 30 rotates, the fan blade 29 can generate a certain downward wind force, enabling the dust to quickly leave the interior of the device after being wiped and removed, and having a rapid cooling effect on the horn antenna 5. Because when the horn antenna 5 is working, the radiation and reflection of the signal wave generated by the signal wave emitter 22 will generate a certain amount of heat, and the high temperature may cause physical changes in the horn antenna 5, such as material expansion, deformation, etc., thereby affecting its ability to radiate and receive signals. After the wiping operation is completed, the lifting motor 27 drives the force-bearing plate 26 to rise again, causing the cleaning roller 31 to leave the center of the horn antenna 5 and enter the interior of the housing 1. At this time, as the force-bearing plate 26 rises, the force-bearing plate 26 gradually comes into contact with the lifting plate body 13 and drives the lifting plate body 13 to rise synchronously. After the lifting plate body 13 rises to the highest position along with the signal driver 16, it comes into contact with the bottom surface of the induction plate 45 and contacts the trigger button on the bottom surface of the induction plate 45. After the trigger button is triggered, the electric telescopic rod 25 starts to contract after receiving the signal. Through the coupling effect of the auxiliary hook ring 24 and the main hook ring 23, the rotating plate body 15 starts to rotate along the connection with the force-bearing plate 26, making the fan blade 29 face the signal component. At this time, the drive motor 28 drives the connecting support rod 30 to rotate again, generating a wind force at the signal component through the cooperation of the fan blade 29 and the small blower 17, enabling it to be quickly cooled during the daily monitoring process, avoiding the performance degradation of the electronic components inside the millimeter-wave radar due to excessive internal temperature of the device, affecting the ranging accuracy, speed measurement accuracy, and direction judgment ability of the radar, and thus affecting the accuracy of fall monitoring.

[0036] The detection mechanism further includes an induction component. The induction component includes: an induction bracelet 4. A signal transmitter 41 is provided on the upper surface of the induction bracelet 4. There is an electrical connection between the signal transmitter 41 and the data processor inside the signal processing box 6. A telescopic band 42 is also provided on the side surface of the induction bracelet 4. A heart rate detector 43 is also provided on the bottom surface of the induction bracelet 4;

[0037] When in use, the induction component is worn on the wrist of the person to be monitored. When the person wearing the induction component is indoors where the device is installed, through the electrical connection between the signal transmitter 41 and the signal processing box 6, the device can lock the position of the wearer faster, so as to react faster when a fall occurs and conduct a secondary precise detection of the position of the wearer. By wearing the induction component, it is also possible to quickly lock the person who actually needs to be detected for a fall in the case of multiple people indoors, so that other people will not interfere with the detection of the device. The heart rate detector 43 at the bottom of the induction component is used to cooperate with the signal component to complete the preliminary fall determination. Because after the wearer falls, the body will have a stress response and the heart rate will increase within a short time. When the signal component detects that the state of the person is suspected of falling and the signal processing box 6 also receives the signal of the rapid increase in heart rate transmitted by the heart rate detector 43, the beam component is immediately activated for precise detection.

[0038] The working principle of the present invention is as follows:

[0039] When in use, the device is fixedly installed on the ceiling of the room through the mounting plate 2. Under normal conditions, the beam component is stored below the storage groove 18 on the bottom surface of the housing 1. During the daily detection process, a small-power signal wave is emitted through the signal wave emitting head 22 to monitor the people in the room. This small-power signal wave does not need to detect the precise state of the people in the room, but only serves as a preliminary detection and determination. If a person in the room has a fall, the induction component worn on the wrist of the user is used for auxiliary detection. After the preliminary determination of a fall, the data processor inside the signal processing box 6 drives the beam component by itself;

[0040] The beam component is used for secondary auxiliary determination after the signal component initially determines that a fall situation has occurred. When receiving the double triggers of the signal component and the induction component, first, the small motor inside the lifting frame 12 starts to rotate. Through the meshing effect with the limiting cross plate 46, it drives the radar signal processor 9 to rise, causing the signal wave transmitting head 22 to also rise accordingly. Subsequently, the beam component rotates through the electric shaft rod 34, flips out from the inside of the storage groove 18, and finally rotates to the lower side of the signal wave transmitting head 22. Then, the small motor inside the lifting frame 12 rotates in the reverse direction, causing the signal wave transmitting head 22 to descend. After descending a certain distance, the engaging convex ring 40 on the surface of the signal wave transmitting head 22 engages with the engaging ring groove 36 on the upper surface of the horn antenna 5. At this time, the signal wave transmitting head 22 and the horn antenna 5 are fixed. Through the horn antenna 5, the signal wave emitted by the signal wave transmitting head 22 can be bundled and transmitted in one direction. At this time, the signal wave transmitting head 22 further increases the output power to strengthen the signal wave and perform more accurate detection of the specified position. After the signal wave transmitting head 22 and the horn antenna 5 are fixed, the data processor set inside the signal processing box 6 senses the position of the induction component worn on the wrist of the indoor personnel. By controlling the driving gear disk 33 to rotate, the engaging ring plate 37 drives the horn antenna 5 and the signal wave transmitting head 22 to rotate horizontally, and the signal wave transmitting head 22 and the horn antenna 5 are vertically adjusted through the positioning motor, so that the horn antenna 5 can detect any position inside the room;

[0041] At this time, the signal wave transmitting head 22 also immediately increases the power of the signal wave, and cooperates with the beam component to perform more accurate detection of the position of the suspected fallen person. In this way, during daily use, when there is no fall situation, the device can only emit signal waves with low power for monitoring. When a suspected fall situation occurs, other components are used to cooperate for high-power determination, so as to reduce power consumption. If it is determined that a fall situation has occurred after detection, the data processor sends a message prompt to the mobile phone bound to the device, and uses the speaker port 7 and the display lamp 8 on the side surface of the signal processing box 6 for prompting to remind the people in other rooms, so that they can more quickly sense the fall situation and come to help the fallen person;

[0042] The auxiliary component is used to provide auxiliary functions for the normal operation of the device. After a detection operation, the beam component is retracted to the bottom surface of the storage groove 18 again through the rotation of the electric shaft rod 34. The limiting side rod 32 cooperates with the limiting pile 21 to fix the position of the beam component. At this time, the bottom surface of the horn antenna 5 contacts and triggers the trigger ring button 20. At this time, the two lifting motors 27 expand and contract, causing the force-bearing plate 26 to descend, so that the cleaning roller 31 descends and enters the interior of the horn antenna 5. At this time, the drive motor 28 makes a primary drive, driving the cleaning roller 31 to wipe the inner side surface of the horn antenna 5 to remove the dust on its surface, so that the horn antenna 5 will not affect the normal signal wave transmission work due to the dust on its surface. When the connecting support rod 30 rotates, the fan blade 29 can generate a certain downward wind force, so that the dust can quickly leave the interior of the device after being wiped and removed, and has a rapid cooling effect on the horn antenna 5. Because when the horn antenna 5 is working, the radiation and reflection of the signal wave generated by the signal wave emitter 22 will generate a certain amount of heat, and the high temperature may cause physical performance changes of the horn antenna 5, such as material expansion, deformation, etc., thus affecting its ability to radiate and receive signals. After the wiping work is completed, the lifting motor 27 drives the force-bearing plate 26 to rise again, so that the cleaning roller 31 leaves the center of the horn antenna 5 and enters the interior of the housing 1. At this time, as the force-bearing plate 26 rises, the force-bearing plate 26 gradually contacts the lifting plate body 13 and drives the lifting plate body 13 to rise synchronously. After the lifting plate body 13 rises to the highest position along with the signal driver 16, it contacts the bottom surface of the induction plate 45 and contacts the trigger button on the bottom surface of the induction plate 45. After the trigger button is triggered, the electric telescopic rod 25 starts to contract after receiving the signal. Through the coupling effect of the auxiliary hook ring 24 and the main hook ring 23, the rotating plate body 15 starts to rotate along the connection with the force-bearing plate 26, so that the fan blade 29 faces the signal component. At this time, the drive motor 28 drives the connecting support rod 30 to rotate again, and generates a wind force at the signal component through the cooperation of the fan blade 29 and the small blower 17, so that it can be quickly cooled during the daily monitoring process, avoiding the decline of the performance of the electronic components inside the millimeter-wave radar due to the too high temperature inside the device, affecting the ranging accuracy, speed measurement accuracy and direction judgment ability of the radar, and thus affecting the accuracy of fall monitoring;

[0043] When in use, the induction component is worn on the wrist of the person to be monitored. When the person wearing the induction component is indoors where the device is installed, through the electrical connection between the signal transmitter 41 and the signal processing box 6, the device can lock the position of the wearer faster, so as to react faster in case of a fall and perform a secondary precise detection of the wearer's position. By wearing the induction component, it is also possible to quickly lock the person who actually needs to be detected for a fall in the case of multiple people indoors, so that other people will not interfere with the detection of the device. The heart rate detector 43 at the bottom of the induction component is used to cooperate with the signal component to complete the preliminary fall determination. Because after the wearer falls, the body will have a stress response and the heart rate will increase within a short time. When the signal component detects that the person's state is suspected of falling and the signal processing box 6 also receives the signal of the rapid increase in heart rate transmitted by the heart rate detector 43, the cluster component is immediately activated for precise detection.

[0044] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
