Description

Technical Field

[0001] The present invention belongs to the technical field related to indoor positioning, and more specifically, particularly relates to an indoor positioning device based on the Internet of Things. Background Art

[0002] The Internet of Things is an Internet of things that connects everything. It mainly uses local networks or Internet and other communication technologies to connect sensors, controllers, machines, people and things in new ways, forming a network that connects people and things, things and things, and realizes informationization, remote management control and intelligence. The application of the Internet of Things makes daily life more information-based, especially for the daily management of mental patients in hospitals. At present, mental patients in clinical hospitals often need medical staff to accompany them to prevent patients from getting lost during free activities. However, due to the large number of patients and the small number of medical staff, the daily work of medical staff has increased a great burden to a certain extent. At the same time, the wristbands worn by inpatients in existing hospitals can only provide brief clinical information, making it difficult to locate patients in real time, and there is a problem of poor practicality. For this reason, we propose an indoor positioning device based on the Internet of Things. However, the indoor positioning in the existing technology has the following defects: In the prior art, when the indoor positioning device is worn on the patient's arm, in order to improve the protection of the indoor positioning device to electronic components, a buffer plate is usually movably installed at the front end of the shell, and the buffer plate is used to provide a buffering effect to prevent impact; however, due to the sliding contact between the buffer plate and the shell, when the patient's hand touches water, water can easily enter the shell along the space between the buffer plate and the shell, thereby causing the electronic components in the shell to be damaged by water, affecting the use of the indoor positioning device.

[0003] In the prior art, during the use of the indoor positioning device, due to moisture in the gas or external water entering the shell, the current indoor positioning device is difficult to process the water in the shell, which causes the water in the shell to contact with electronic components, causing short circuit damage to the electronic components, thereby affecting the use of the indoor positioning device.

[0004] In the prior art, when the indoor positioning device is in use, it is not only necessary to protect the electronic components in the shell from impact, but also to dissipate the heat of the electronic components in the shell; however, in order to prevent the electronic components from getting damp, the current indoor positioning device usually makes the gas flow efficiency in the shell low, resulting in poor heat dissipation effect of the electronic components.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides an indoor positioning device based on the Internet of Things. Through the arrangement of the first airbag, the second airbag, and the first connecting channel, the movable plate moves close to the fixed frame to squeeze the second airbag, so that the gas in the second airbag enters the first airbag through the first connecting channel. The first airbag is filled with gas and expands. The first airbag expands to expand the surface area of ​​the outside of the first airbag, thereby increasing the contact area between the water attached to the outside of the first airbag and the gas, which is conducive to air drying the water in the storage chamber. Then, through the arrangement of the piston plate, the push rod, the elliptical plate, the telescopic connecting pipe, the rotating shaft, the wind wheel, the circular plate, and the through hole, the piston plate moves to squeeze the gas in the air pressure chamber, so that the gas in the air pressure chamber enters the telescopic connecting pipe, and the gas in the telescopic connecting pipe increases continuously.

The rotation of the circular plate drives the rotation of a number of through holes. The rotation of the several through holes causes the high-pressure gas in the shell to be spirally ejected, which is beneficial to further expand the contact area between the water and the gas in the storage chamber and improve the air-drying effect on the water in the storage chamber.

[0018] The present invention provides an indoor positioning device based on the Internet of Things. Through the arrangement of a storage box, a second one-way valve, a movable plate, and a pyramid frame, the movement of a piston plate drives the movement of a buffer assembly, the movement of the buffer assembly drives the movement of an elastic member, the movement of the elastic member drives the movement of a rectangular frame and a buffer plate, and the movement of the buffer plate, rectangular frame, movable plate, and pyramid frame expands the space of the installation cavity and reduces the space of the storage cavity, which is conducive to squeezing the gas and water in the storage cavity through the second one-way valve into the storage box for storage.

[0019] The indoor positioning device based on the Internet of Things of the present invention, through the setting of the protrusions and the spring, under the guiding action of the several protrusions and the elastic force of the spring, makes the push rod and the piston plate move back and forth in a small range.

[0037] Preferably, see Attachment Figure 1 A watch strap 12 is hingedly provided at both ends of the outer shell 10, and the two watch straps 12 are locked by snap fit, and both watch straps 12 are made of silicone.

[0038] Specific use of the present invention: When the medical staff puts the indoor positioning device on the patient, they wrap the two straps 12 around the patient's wrist and lock and fix the two straps 12 through the buckle structure. The battery in the electronic component assembly 46 supplies power to the positioning chip and the alarm. The positioning chip in the electronic component assembly 46 shares the real-time position of the indoor positioning device through the Internet of Things, and controls the alarm in the electronic component assembly 46 through the Internet of Things to sound an alarm to remind the wearer.

[0039] First, when water outside the housing 10 enters the housing 10 along the space between the housing 10 and the buffer plate 11, the water enters the storage chamber 17, and the water is guided by the outer wall slope of the pyramid frame 15, so that the water moves to the outside of the first airbag 22. At this time, the control system controls the two stepper motors 37 to start, and the stepper motors 37 start to drive the elliptical plate 38 to rotate. Through the large radius at the opposite ends of the elliptical plate 38 and the small radius at the other opposite ends of the elliptical plate 38, one end of the push rod 40 contacts the outer wall of the elliptical plate 38, so that the elliptical plate 38 rotates to guide and squeeze the push rod 40.

[0040] Secondly, when one end of the push rod 40 moves from the end of the elliptical plate 38 with a smaller radius to the end of the elliptical plate 38 with a larger radius, the push rod 40 is guided by the elliptical plate 38 to push the push rod 40 and the piston plate 20 to move. The movement of the piston plate 20 drives the buffer assembly to move, the movement of the buffer assembly drives the elastic member 47 to move, the movement of the elastic member 47 drives the rectangular frame 13 and the buffer plate 11 to move, the buffer plate 11, the rectangular frame 13, the movable plate 14, and the pyramid frame 15 move to expand the space of the installation cavity 18 and reduce the space of the storage cavity 17, which is conducive to squeezing the gas in the storage cavity 17 through the second one-way valve 43 into the storage box 34 for storage. Among them, the movement of the piston plate 20 stretches the spring 41 to generate elastic force.

[0041] At the same time, the electronic component assembly 46 in the protective shell 44 dissipates heat through the two heat dissipation holes 45, so that the hot air generated by the electronic component assembly 46 enters the installation cavity 18. The piston plate 20 moves through the first one-way valve 33 to suck the gas in the installation cavity 18 into the air pressure cavity 21, thereby reducing the heat in the installation cavity 18, which is beneficial to the heat dissipation of the electronic component assembly 46.

[0042] Next, when one end of the push rod 40 moves from the end of the elliptical plate 38 with a larger radius to the end of the elliptical plate 38 with a smaller radius, the piston plate 20 and the push rod 40 are moved and reset under the elastic force of the spring 41, so that one end of the push rod 40 contacts the outer wall of the elliptical plate 38. The movement of the piston plate 20 drives the buffer assembly to move and reset, the movement of the buffer assembly drives the elastic member 47 to move, the movement of the elastic member 47 drives the rectangular frame 13, the buffer plate 11, and the movable plate 14 to move, and the movable plate 14 moves close to the fixed frame 19 to squeeze the second airbag 23, so that the gas in the second airbag 23 enters the first airbag 22 through the first connecting channel 24, and the first airbag 22 expands after being filled with gas. The expansion of the first airbag 22 expands the surface area of ​​the outside of the first airbag 22, thereby increasing the area of ​​contact between the water attached to the outside of the first airbag 22 and the gas, which is conducive to air drying the water in the storage chamber 17.

[0043] At the same time, the piston plate 20 moves to squeeze the gas in the air pressure chamber 21, so that the gas in the air pressure chamber 21 enters the telescopic connecting tube 25, and the gas in the telescopic connecting tube 25 increases continuously. When the air pressure received by the pressure regulating valve 42 reaches the specified value, the pressure regulating valve 42 opens, so that the high-pressure gas in the telescopic connecting tube 25 can be ejected into the housing 26. The high-pressure gas contacts the wind wheel 28, driving the wind wheel 28 and the rotating shaft 27 to rotate. The rotation of the rotating shaft 27 drives the circular plate 29 to rotate. The rotation of the circular plate 29 drives the rotation of the plurality of through holes 31. The rotation of the plurality of through holes 31 causes the high-pressure gas in the housing 26 to be ejected spirally, which is conducive to further expanding the contact area between the water and the gas in the storage chamber 17 and improving the air drying effect on the water in the storage chamber 17. Among them, the rotation of the circular plate 29 drives the annular plate 30 to slide in an annular manner in one end of the housing 26, so that the circular plate 29 rotates smoothly.

[0044] Under the guidance of the outer wall of the elliptical plate 38 on the push rod 40 and the elastic force of the spring 41, the piston plate 20 moves back and forth, and the piston plate 20 moves back and forth to continuously suck the gas in the installation chamber 18 into the air pressure chamber 21, and then squeezes and sprays the gas in the air pressure chamber 21 into the storage chamber 17, so that the water in the storage chamber 17 can be continuously dried. Finally, the buffer plate 11, the rectangular frame 13, the movable plate 14, and the pyramid frame 15 move to expand the space of the installation chamber 18 and reduce the space of the storage chamber 17, which is conducive to squeezing the gas in the storage chamber 17 through the second one-way valve 43 into the storage box 34 for storage. The buffer plate 11, the rectangular frame 13, the movable plate 14, and the pyramid frame 15 move back and forth in the housing 10, and the space of the installation chamber 18 is alternately expanded and reduced, which is conducive to promoting the flow of gas in the installation chamber 18, so that the electronic component assembly 46 can be cooled.

[0045] Then, the elliptical plate 38 rotates to drive the plurality of protrusions 39 to rotate, and one end of the push rod 40 contacts the outside of the protrusion 39, so that the protrusion 39 guides the push rod 40, pushes the push rod 40 and the piston plate 20 to move, and the movement of the piston plate 20 stretches the spring 41 to generate elastic force. When one end of the push rod 40 is out of contact with the outside of the protrusion 39, the piston plate 20 and the push rod 40 can be moved and reset under the elastic force of the spring 41. In this way, under the guiding action of the plurality of protrusions 39 and the elastic force of the spring 41, the push rod 40 and the piston plate 20 can move back and forth in a small range. The piston plate 20 drives the buffer assembly to move back and forth slightly, and the buffer assembly drives the elastic member 47, the rectangular frame 13, the buffer plate 11, the pyramid frame 15, and the first airbag 22 to move back and forth slightly, thereby causing the pyramid frame 15 and the first airbag 22 to vibrate, further causing the water in the storage chamber 17 to move to the outside of the first airbag 22, and causing the water outside the first airbag 22 to vibrate and diffuse, thereby increasing the contact area between water and gas.

[0046] At the same time, under the guiding effect of the elliptical plate 38, the guiding effect of the plurality of protrusions 39 and the elastic force of the spring 41, the push rod 40 and the piston plate 20 move back and forth in a small range at the same time while they move back and forth in a large range. This makes it easier for the rectangular frame 13, the buffer plate 11, the pyramid frame 15 and the first airbag 22 to move back and forth in a small range at the same time while they move back and forth in a large range in the housing 10, which is beneficial for squeezing the water and gas in the storage chamber 17 through the second one-way valve 43 into the storage box 34 for storage.

[0047] Finally, when the buffer plate 11 collides with an external object, the outer surface of the buffer plate 11 collides with the external object, generating an inward impact force on the buffer plate 11, and the buffer plate 11 moves toward the inside of the housing 10. The movement of the buffer plate 11 drives the rectangular frame 13 to move, and the movement of the rectangular frame 13 pushes the two elastic members 47 to move, and the movement of the two elastic members 47 pushes the two first movable blocks 48 away from each other. The first movable block 48 moves to squeeze the second elastic member 51, and the elastic force generated by the compression of the second elastic member 51 has a buffering effect on the first movable block 48.

[0048] The movement of the first movable block 48 drives the movement of the two second movable blocks 49, and the sides of the two second movable blocks 49 that are far away from each other respectively contact the inclined surfaces of the sides of one end of the two first elastic members 50 that are close to each other. Thus, the movement of the first movable block 48 drives the movement of the two second movable blocks 49, so that the degree of extrusion between the second movable blocks 49 and the first elastic members 50 is continuously strengthened, which is beneficial to improving the buffering effect on the buffer plate 11.

[0049] At the same time, the second elastic member 51 is squeezed, so that the gas in the second elastic member 51 enters the two first elastic members 50 respectively through the two second connecting channels 32, so that the two first elastic members 50 are filled with gas and expand. The two first elastic members 50 expand, further increasing the degree of squeezing between 9 and the first elastic member 50, and further increasing the buffering effect on the buffer plate 11.

[0050] At the same time, the movement of the first movable block 48 drives the two second movable blocks 49 to move, and through a plurality of pairs of elastic protrusions 52, they are respectively squeezed and frictionally contacted with the inclined surfaces of the two second movable blocks 49. The movement of the two second movable blocks 49 continuously increases the squeezing degree of the plurality of pairs of elastic protrusions 52, thereby continuously increasing the friction force between the second movable blocks 49 and the elastic protrusions 52, further improving the buffering effect of the buffer assembly on the buffer plate 11, and preventing the indoor positioning device from being damaged by a severe impact of the patient.

[0051] The present invention is an indoor positioning device based on the Internet of Things. Through the arrangement of the first airbag 22, the second airbag 23, and the first connecting channel 24, the movable plate 14 moves close to the fixed frame 19 to squeeze the second airbag 23, so that the gas in the second airbag 23 enters the first airbag 22 through the first connecting channel 24. The first airbag 22 expands after being filled with gas. The expansion of the first airbag 22 expands the surface area of ​​the outside of the first airbag 22, thereby increasing the contact area between water attached to the outside of the first airbag 22 and the gas, which is beneficial to air-drying the water in the storage chamber 17. Then, through the arrangement of the piston plate 20, the push rod 40, the elliptical plate 38, the telescopic connecting tube 25, the rotating shaft 27, the wind wheel 28, the circular plate 29, and the through hole 31, the piston plate 20 moves to squeeze the gas in the air pressure chamber 21, so that the gas in the air pressure chamber 21 enters the telescopic connecting tube 25, and the gas in the telescopic connecting tube 25 increases continuously. When the air pressure received by the pressure regulating valve 42 reaches a specified value, the pressure regulating valve 42 opens, so that the high-pressure gas in the telescopic connecting tube 25 is ejected into the housing 26. The high-pressure gas contacts the wind wheel 28, drives the wind wheel 28 and the rotating shaft 27 to rotate, the rotation of the rotating shaft 27 drives the circular plate 29 to rotate, the rotation of the circular plate 29 drives the plurality of through holes 31 to rotate, and the rotation of the plurality of through holes 31 causes the high-pressure gas in the housing 26 to spirally eject, which is beneficial to further expand the contact area between the water and the gas in the storage chamber 17 and improve the air drying effect on the water in the storage chamber 17.

[0052] In the indoor positioning device based on the Internet of Things of the present invention, the storage box 34, the second one-way valve 43, the movable plate 14, and the pyramid frame 15 are arranged, the piston plate 20 moves to drive the buffer assembly to move, the buffer assembly moves to push the elastic member 47 to move, the elastic member 47 moves to push the rectangular frame 13 and the buffer plate 11 to move, the buffer plate 11, the rectangular frame 13, the movable plate 14, and the pyramid frame 15 move to expand the space of the installation cavity 18 and reduce the space of the storage cavity 17, which is conducive to squeezing the gas and water in the storage cavity 17 through the second one-way valve 43 into the storage box 34 for storage. Then, the buffer plate 11, the rectangular frame 13, the movable plate 14, and the pyramid frame 15 move back and forth in the housing 10, and the space of the installation cavity 18 is alternately expanded and reduced, which is conducive to promoting the gas flow in the installation cavity 18, so that the electronic component assembly 46 can be cooled.

[0053] In the indoor positioning device based on the Internet of Things of the present invention, the push rod 40 and the piston plate 20 are moved back and forth in a small range by setting the protrusions 39 and the spring 41 under the guiding action of the protrusions 39 and the elastic force of the spring 41. The piston plate 20 drives the buffer assembly to move back and forth in a small range, and the buffer assembly drives the elastic member 47, the rectangular frame 13, the buffer plate 11, the pyramid frame 15, and the first airbag 22 to move back and forth in a small range, so that the pyramid frame 15 and the first airbag 22 are shaken, and the water in the storage chamber 17 is further moved to the outside of the first airbag 22, and the water outside the first airbag 22 is shaken and diffused, so as to increase the contact area between water and gas, which is conducive to the air drying of the water entering the housing 10.
