Description

Technical Field

[0001] The present invention relates to elderly care technology, and in particular to a smart home elderly care service system based on the Internet of Things. Background Art

[0002] With the increasingly serious problem of aging population in China, elderly care has become a rigid demand. The number of elderly people in China is huge, and the elderly care industry has huge market potential. In addition, due to the gradual increase in labor costs, it is an inevitable trend for machines to replace labor. In the elderly care industry, it is also imperative for machines to replace labor. For elderly care, it is very necessary to regularly check basic physical indicators, the main indicators are blood pressure, heart rate, weight, height, BMI (health index), sense of balance, etc.

[0003] At present, there are generally two young people taking care of four elderly people in a family. Due to the influence of thousands of years of loyalty and filial piety culture, most elderly people are very resistant to the centralized elderly care in nursing homes, so most elderly people choose to live at home. However, due to the high work pressure of young people, it is impossible for them to accompany the elderly at home all the time. Therefore, young people cannot know in time when the elderly get lost, fall down, fall ill, etc. This can easily lead to many tragedies, such as the elderly cannot be found after they get lost, and they cannot be treated in time after falling down or falling ill, resulting in death. In addition, the physical condition of the elderly is very special and needs to be monitored regularly. Once the young people are busy, they cannot monitor in time, and they cannot find out the physical abnormalities of the elderly in time, which may eventually lead to the deterioration of the physical health of the elderly.

[0004] Therefore, the inventor has designed a smart home-based elderly care service system based on the Internet of Things, which can monitor the physical condition and status of the elderly, and can also provide assistance and confirmation to the elderly who need services through the Internet.

[0086] When in use, both the wearable device and the terminal can send door opening commands to the smart door lock, so that the smart door lock opens to facilitate people outside the door to enter. The door lock camera can obtain the image of the person requesting to enter, so that the identity of the person requesting to enter can be identified through image recognition technology.

Its charging access terminal is electrically connected to the integrated interface, and the integrated interface is used to be electrically connected to an external power line to charge the battery. The charging and discharging circuit also supplies power to various electrical devices.

[0106] The coil generates a magnetic field when energized, thereby unlocking the wearable lock of the wearable device. The coil is connected in series with the contactor and then electrically connected to the battery. When the contactor is turned on, the battery can power the coil.

[0107] The single-chip microcomputer is respectively connected to the control end of the contactor, the signal end of the microphone, the signal end of the speaker, the signal end of the camera, the signal end of the positioning module, the signal end of the heart rate monitoring chip, the signal end of the angular velocity sensor, and the signal end of the network module. The static contact of the contactor is electrically connected to the positive pole of the battery, the normally open contact is electrically connected to one end of the coil, and the other end of the coil is electrically connected to the negative pole of the battery. When the contactor is closed, the battery supplies power to the coil, so that the coil generates a magnetic field;

[0108] The database and electronic map are stored on the server, and the CPUs of the server, terminal, single-chip microcomputer, and integrated evaluation machine are all interconnected. This design enables all data to be stored on the server and each device to obtain data from the server.

[0109] When in use, the wearer's safe activity range, that is, the electronic fence, can be slid through the electronic map. Once the wearer walks out of the electronic fence, the microcontroller sends a warning message to the terminal, so that the guardian can deal with it in time to prevent the wearer from getting lost.

[0110] In this embodiment, the wearable end may be a bracelet.

[0111] See also Figure 5In actual use, the wearing end is easily forgotten by the elderly, and thus forgotten to carry, which makes the present invention meaningless. In view of this, the inventor has set up a wearing lock to solve this problem. The wearing lock includes a first belt body A110, a second belt body A130, and a lock body A120. One end of the first belt body A110 and the second belt body A130 are respectively mounted on the outer shell of the wearing end. The other end of the first belt body A110 is assembled and fixed to the lock body A120. The lock body A120 is respectively provided with a through groove A121, an unlocking groove A122, and a locking block hole A123. The through groove A121 penetrates the lock body A120, and the other end of the second belt body A130 passes through the through groove A121.

[0112] The second belt body A130 is provided with a plurality of locking grooves A131 distributed along its length direction, and the locking groove A131 is engaged with one end of the locking block A230 to lock the first belt body A110 and the second belt body A130 together, and the locking block A230 is installed on the magnet block A220, and the magnet block A220 is made of a permanent magnet. The magnet block A220 is also assembled with the top of the arc spring sheet A240, and the two ends of the arc spring sheet A240 are respectively pressed against the inner side of the screw plug A250, and the arc spring sheet A240 is elastic, so as to apply an elastic force to the magnet block A220 to push the locking groove A131, so as to keep the locking block A230 assembled with the locking groove A131, and the screw plug A250 is assembled with the locking block hole A121, and the magnet block A220 is engaged with the locking block hole A121 and can be slidably assembled.

[0113] A soft iron plate A210 is installed in the unlocking groove A122, and a soft iron column A211 is installed on the soft iron plate A210. A coil A310 is wound around the outside of the soft iron column A211. The two ends of the coil A310 are powered by different wires A320, and the wires A320 are built in the first belt body A110 and / or the second belt body A130. The soft iron plates A210 and A210 are made of soft iron, and can generate a magnetic field after the coil is energized. The magnetic field magnetizes the soft iron plates A210 and A210, making the soft iron plates A210 and A210 magnetic. The soft iron plates A210 and A210 are opposite to the magnet block A220 with the same poles to generate a repulsive magnetic force, so that the magnetic force drives the magnet block A220 to push the arc spring sheet A240 to deform until the lock block A230 exits the lock groove to complete the unlocking. In this embodiment, the terminal sends a control instruction to the single-chip microcomputer, and the single-chip microcomputer controls the contactor to be turned on for a period of time. This design can effectively prevent the wearer from taking it off by himself by only unlocking it through the terminal. At the same time, it can also be unlocked by attracting a magnet block on the outside of the screw plug A250, but this method requires special equipment, which is generally not used by the elderly. This is a backup mechanical unlocking.

[0119] When in use, the tester stands on two weighing plates 130 with both feet, and the weighing sensor 410 is compressed to generate an electrical signal, which is input into the CPU.

The locking bolt 330 passes through the top plate 160 and is pressed against the detection end plate 222 located above, so that the detection module 200 cannot rotate.

The detection slider 451 is engaged with the detection slot 2121 and can be slidably assembled. The detection mounting plate 452 is assembled with the belt 550. The belt 550 is respectively passed around two pulleys 551 to form a belt transmission mechanism. The two pulleys 551 are respectively mounted on different pulley shafts 350. The two pulley shafts 350 are respectively assembled with the second detection vertical plate 212 and the third detection vertical plate 213 so as to be rotatable in a circle; one of the belts The axle 350 is assembled with the first gear 540, and the first gear 540 is meshed with the rack part 531 on one side of the rack 530 to form a gear-rack transmission mechanism. Rack parts 531 are respectively provided on both sides of the rack 530, and the rack part 531 on the other side is meshed with the second gear 560 to form a gear-rack transmission mechanism. The second gear 560 is sleeved on the lifting motor shaft 421, and one end of the lifting motor shaft 421 passes through the third detection vertical plate 213 and is installed in the lifting motor 420. After the lifting motor 420 is started, it can drive the lifting motor shaft 421 to rotate, and the lifting motor shaft 421 drives the rack 530 to move through the second gear 560, and the rack 530 drives the first gear 540 to rotate, and the first gear drives the belt 550 to run, and the belt 550 drives the detection slider 451 to slide in the detection slide groove 2121, thereby driving the laser sensor 450 to move along the detection slide groove 2121.

[0123] Preferably, the rack 530 is further provided with a rack slider 532, which is engaged with and slidably assembled with the rack slide groove 2131, and the rack slide groove 2131 is provided on the third detection vertical plate 213. This design can make the rack run more smoothly.

[0124] The laser sensors 450 on the two detection modules 200 are either receivers or transmitters. The transmitter emits laser light, and the receiver generates an electrical signal after receiving the laser light, thereby determining that there is no obstacle in the middle. Fig.14When the laser sensor moves, a line 910 is formed. When the laser sensor is blocked by the human body 900, a blocking line 911 is formed. The two ends of the blocking line 911 are connected to obtain the first curve 921 and the second curve 922; the physiological characteristic curve of the side of the human body is compared with the first curve 921 and the second curve 922, and the unreasonable curvature 920 is eliminated (which can be obtained by establishing a mathematical model and then training with big data), and the blocking line 911 of the unreasonable part 920 is compensated by the physiological curve simulation, and then the two ends of each blocking line 911 are connected smoothly to obtain a simulated curve 930, and the simulated curve approaches the side curve of the human body, and then the corresponding parts of the simulated curve and each blocking line 911 are connected and divided by a straight line 940, and the midpoints of each straight line are connected to obtain a simulated midline, and the simulated midline 950 is fitted with the midline of the side curve of the human body to calculate the height. This design can effectively solve the problem of height measurement accuracy when hunching and bending, and the data is more accurate, which is greatly beneficial to the health management of the elderly.

[0125] Of course, under the premise that the accuracy requirement is not high, the end point of the blocking line 911 can be directly connected, and then fitted with the midline of the human physiological curve to infer the height of the tester. Specifically, the position of the blocking line 911 located on the side physiological curve of the human body is calculated based on the first curve 921, the second curve 922, and the blocking line 911, and then the height is calculated. For example, the blocking line 911 located at the waist, abdomen, chest, shoulder, neck, and head is calculated. According to the law of the human physiological curve, the height above the waist can be roughly calculated, and then the height can be calculated by combining the vertical spacing between the bottom laser sensor and the weighing plate 130. This method combined with existing big data calculations and neural network simulations can greatly improve the final calculation accuracy.
