For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Although existing lamps have the function of detecting whether a person has fallen and calling for help from the hospital, rescue can only be started after the paramedics arrive at the scene. During the period from calling for help to the arrival of the paramedics, family members are unable to scientifically rescue the fallen person due to their limited professional ability, especially in the case of coma or serious illnesses such as fractures after the fall.

[0033] In order to solve the technical problem that a fallen person cannot receive timely rescue, this embodiment discloses a first aid system, which includes a smart home system and a server. The smart home system includes a first aid device and smart home appliances, etc., and each device is connected to a home network to realize information transmission.

[0034] The first aid device is specifically a ceiling lamp or a wall lamp, which can monitor vital signs and provide lighting. Figure 1 and 2 As shown, the first aid device includes a main body, a radar component 3 and a lighting lamp. The main body includes a base and a mounting plate 1, and the lighting lamp is arranged on the mounting plate 1, wherein the lighting lamp includes a plurality of lamp beads 2, and the plurality of lamp beads 2 are arranged in a ring shape, specifically in a circular shape; specifically, they are arranged at the outer edge of the mounting plate 1. The plurality of lamp beads 2 are arranged in a ring shape, so that the light emitted by the lighting lamp can emit light in all directions at 360°, and the intensity of the light emitted in each direction is the same, thereby ensuring the uniformity of indoor lighting. A lampshade 5 is provided at the bottom of the mounting plate 1, which can make the light emitted by the lamp beads 2 more uniform. The lampshade 5 is made of a material that can transmit millimeter waves, which can ensure the normal operation of the radar component 3.

[0035] Although in this embodiment, the plurality of lamp beads 2 are arranged in a circular ring, this is not a limitation of the present invention. Without departing from the principle of the present invention, in other embodiments, the plurality of lamp beads 2 may also be arranged in a triangular ring, a square ring, or a polygonal ring. This does not deviate from the basic principle of the present invention and will fall within the protection scope of the present invention.

[0036] The first aid device also includes a driving member, a driving member and an output end of the driving member, one of which is arranged on the base, and the other is arranged on the mounting plate 1; the driving member can drive the lighting lamp to swing according to the position of the fallen person, so as to aim at the fallen person. Specifically, the driving member includes a driving motor and a swinging electric cylinder, wherein the driving motor is arranged on the base, and the swinging electric cylinder is rotatably arranged on the base, and the driving motor can drive the swinging electric cylinder to rotate; the output end of the swinging electric cylinder is connected to the mounting plate 1, specifically connected to the back of the mounting plate 1, and the swinging electric cylinder can drive the mounting plate 1 to swing, and then drive the lighting lamp to swing. The driving motor and the swinging electric cylinder cooperate to enable the mounting plate 1 to swing at various angles, that is, to achieve adjustment without dead angles. No matter where the fallen person is, the driving motor and the swinging electric cylinder cooperate to drive the lighting direction of the lighting lamp toward the fallen person, so that family members or rescuers can rescue the fallen person in a brighter environment.

[0037] The first aid device also includes a control panel 4, which is arranged on the mounting plate 1, specifically on the same side of the mounting plate 1 as the lamp beads 2. The drive motor and the swing electric cylinder are both electrically connected to the control panel 4, and the position of the fallen person detected by the radar component 3 of the control panel 4 is used to control the operation of the drive motor and the swing electric cylinder, thereby controlling the swing angle of the lighting lamp. A wireless communication module is provided on the control panel 4, and the wireless communication module is wirelessly connected to the home network. The control panel 4 can receive information through the home network, and then control the operation of the first aid device according to the received information. The control panel 4 can also transmit the information detected by the first aid device to the home network, and then transmit it to other devices in the smart home system.

[0038] Regarding the driving member, it should be noted that although the driving member in this embodiment includes a driving motor and a swinging electric cylinder, this is not a limitation of the present invention. Without departing from the principle of the present invention, in other embodiments, those skilled in the art may also select two swinging electric cylinders to cooperate to swing the mounting plate 1. Specifically, one swinging electric cylinder drives the other swinging electric cylinder to swing forward and backward, and the other swinging electric cylinder drives the mounting plate 1 to swing left and right. The two swinging electric cylinders cooperate to realize the swinging of the mounting plate 1 at various angles, thereby enabling the lighting lamp to swing and illuminate the person who has fallen. This does not deviate from the basic principle of the present invention, and therefore falls within the protection scope of the present invention.

[0039] The radar assembly 3 is arranged on the body, specifically on the mounting plate 1, and is arranged on the same side as the control panel 4; the two are arranged at intervals. Specifically, a plurality of lamp beads 2 are arranged around the control panel 4 and the radar assembly 3, that is, the control panel 4 and the radar assembly 3 are both located on the inner side of the lamp beads 2. The radar assembly 3 is used to detect whether a person falls. Specifically, the radar assembly 3 includes a millimeter wave radar and a control module. The millimeter wave radar is used to detect the body contour of the person, and is specifically used to obtain the peripheral body contour of the person through the millimeter wave emitted by the millimeter wave radar. The control module is used to determine whether the person falls according to the peripheral body contour information obtained by the millimeter wave radar; specifically, it is mainly based on the distance between the contour of the upper body of the person and the ground and the speed of descent to determine whether the person falls. If the upper body at least partially fits the ground or the distance from the ground is less than the preset distance, and the descent speed of the upper body is greater than the preset speed, it is determined that the person falls. Only the millimeter wave radar is needed to obtain the body contour, and the acquisition method is simple and fast; the judgment method is also relatively simple. If the distance between the upper body and the bottom surface is greater than the preset distance, it means that the person is in a normal standing or sitting posture, and it is determined that the person has not fallen. Alternatively, if the descending speed of the upper body is less than the preset speed, it means that the person may lie down actively, and in this case it is determined that the person has not fallen.

[0040] After a person falls, an alarm can be issued, specifically through a smart home appliance or first aid device (the smart home appliance can be a smart phone, smart tablet or smart TV, etc.), to notify family members at home so that they can provide timely rescue to the fallen person. Of course, an alarm can also be issued to the smart phones of family members who are away through the smart home network, so that the family members who are away can know that a fall accident has occurred at home, so that the family members can return home in time to rescue the fallen person or observe the status of the fallen person through monitoring and decide whether to call 120 for rescue.

[0041] The control module is connected to the control panel 4 for communication. The radar component 3 can not only detect whether a person falls, but also send the fall information to the control panel 4 if the person falls, and then send a distress message or an alarm message. The radar component 3 can also determine the position of the person who falls, and send the position of the person who falls to the control panel 4. The control panel 4 controls the rotation of the drive motor according to the position of the person who falls, and drives the swing electric cylinder to swing, so that the lighting lamp swings and aims at the person who falls to illuminate, so that family members or rescuers can rescue the person who falls.

[0042] The first aid device also includes a battery (not shown in the figure), the radar assembly 3 is connected to the battery, the battery is used to power the radar assembly 3, and the control panel 4 is also electrically connected to the battery, and the battery can also power the control panel 4. The battery is specifically arranged on the base, and the battery is specifically a battery. The battery is connected to a household power supply, that is, a thermal power connected to the power grid. When the light is turned on, the power supply can charge the battery; when the light is not turned on, the battery can also continue to power the radar assembly 3, so that the radar assembly 3 can continue to detect whether a person has fallen. The driving member is also electrically connected to the battery, and the battery is used to power it, so that the driving member can drive the mounting plate 1 to swing, and then the lighting lamp is aimed at the fallen person.

[0043] The lighting lamp also includes a power adapter, which is connected to a power source. The function of the power adapter is to convert 220 volts of alternating current into direct current for use by the LED lamp beads 2; the power adapter has the same structure and principle as the power adapter of an ordinary LED lamp in the prior art, and the specific structure of the power adapter is not described in detail in this application.

[0044] The first aid device also includes a controller, which is electrically connected to the illuminating lamp, and the controller can adjust the brightness of the illuminating lamp. Specifically, the controller is arranged in the power adapter, and it can adjust the brightness of the lamp bead 2 according to the adjustment instruction, thereby adjusting the brightness of the illuminating lamp.

[0045] The first aid device also includes an intelligent terminal, which is communicatively connected to the controller, and the intelligent terminal can adjust the brightness of the lighting lamp through the controller. Specifically, the intelligent terminal can send adjustment instructions to adjust the brightness of the lighting lamp; it can also adjust the light color and display mode of the lighting lamp. The intelligent terminal can specifically be a remote control, and can also send infrared signals to the power adapter to adjust the brightness, light color and display mode of the lighting lamp. The intelligent terminal can also be a smart phone, a smart tablet or a smart bracelet, which can be wirelessly connected to the power adapter, specifically through the home wireless network of the smart home system, or through Bluetooth; of course, it can also transmit signals through infrared to adjust the brightness, light color and display mode of the lighting lamp.

[0046] The lighting lamp is connected to a battery, and the battery can power the lighting lamp. The battery can directly power the lamp bead 2, rather than through the AC-to-DC converter of the power adapter. When the power is off, the controller can also control the battery to power the lighting lamp, so that the lighting lamp illuminates. Specifically, when the power adapter detects a power outage but receives a command to turn on the light, the controller can control the battery to power the lighting lamp, so that the lighting lamp can also illuminate when the power is off at home.

[0047] When a person falls accidentally but is fine, or when the person lies down quickly, the person's fall may be detected, which is a false detection. Since the fall monitoring by radar component 3 alone may result in false detection and false alarm, in order to improve the accuracy of the monitoring results, when a person's fall is detected, it can be confirmed by asking whether the person has really fallen.

[0048] Specifically, the first aid device also includes a microphone and a speaker, both of which are electrically connected to the control panel 4. The speaker can emit corresponding sounds according to the instructions issued by the control panel 4. The sound picked up by the microphone can be sent to the control panel 4, which is processed by the control panel 4 to determine that a specific instruction has been received.

[0049] When the radar component 3 detects that a person has fallen, the detected information is sent to the control panel 4, and then the control panel 4 controls the speaker and microphone to ask whether the person has really fallen. Specifically, the control panel 4 controls the speaker to emit a sound to ask whether the fall really occurred. Specifically, the control panel 4 controls the speaker to emit "Hello, have you fallen?", "Hello, have you fallen?", "Hello, have you fallen?" or "Hello, have you fallen?" and other voices to ask the user. If the microphone receives a fall response from the person within the preset time (specifically, it can be a response instruction such as "yes", "fallen", "fallen" or "fallen"), it is confirmed that the person has fallen, and then an alarm or other operations are performed. Or, if the control panel 4 does not receive any response within the preset time, it is very likely that the person has fallen and then fainted, causing the person who fell to be unable to respond in time. At this time, it is also determined that the person has fallen, and then an alarm or other operations are performed.

[0050] If the microphone receives a response from the person that he / she has not fallen within the preset time (specifically, it can be a response instruction such as "no", "did not fall", "did not fall", "did not fall" or "did not fall"), it is determined that the person has not fallen, and no other processing is required. Among them, the preset time is specifically 2 minutes. Generally, after a fall, a conversation can be carried out after a slight buffer. Therefore, 2 minutes can meet the general buffer. In other embodiments, the preset time can also be 3 minutes, 5 minutes or 10 minutes, etc., which can be set according to the actual situation of the people at home.

[0051] Among them, the microphone and the speaker are both arranged on the mounting plate 1 and are located on the inner side of the lamp bead 2. The speaker and the microphone are located on the inner side of the lamp bead 2, which does not affect the outward illumination of the light emitted by the lamp bead 2, and can ensure the illumination effect of the lighting lamp. Moreover, the millimeter wave radar is located below the lamp bead 2 in height, so that the millimeter waves emitted by the millimeter wave radar will not be blocked by the lamp bead 2, etc., and its detection effect is guaranteed. In addition, the millimeter wave radar is also located below the microphone and the speaker in height, ensuring that the millimeter wave emitted by the millimeter wave radar will not be blocked by the lamp bead 2, etc., and its detection effect is guaranteed.

[0052] Although in this embodiment, the speaker and microphone of the first aid device are used to confirm whether the person has really fallen, this is not a limitation of the present invention. Without departing from the principle of the present invention, in other embodiments, those skilled in the art may also select other smart home appliances to perform voice calls to confirm whether the person has fallen. This does not deviate from the protection scope of the present invention and therefore falls within the protection scope of the present invention.

[0053] Specifically, the smart home appliance has a speaker and a microphone, and can make voice calls. Specifically, it can be a smart TV, a smart tablet or a smart phone, etc., and the smart home appliance is connected to the smart home system. Specifically, the smart home appliance is used to ask whether the person really fell. Specifically, the smart home appliance makes a sound to ask whether the fall really occurred. Specifically, the voice of "Hello, did you fall?" can be issued to ask the user. If a fall response is received from the person within a preset time (specifically, it can be a response instruction such as "yes", "fallen", "fallen" or "fallen") or no response is received within a preset time (at this time, it is very likely that the person has fallen into a coma after the fall), it is determined that the person has fallen; then an alarm is issued. If a non-fall response is received from the person within a preset time (specifically, it can be a response instruction such as "no", "no fall", "no fall", "no fall" or "no fall"), it is determined that the person has not fallen.

[0054] The smart home appliance is arranged indoors, specifically in the same room as the first aid device; for example, both are installed in the bedroom or living room. The smart home appliance has a camera that can record the loaded scene and can also record the patient's facial video. The smart home appliance is connected to the home network communication, and the scene recorded by the smart home appliance can be transmitted to the home network, and then transmitted to other smart home appliances connected to the smart home system. Through the above-mentioned settings, the smart home appliance can specifically record the video of the fallen person and the scene. Preferably, in the present embodiment, the smart home appliance is a smart TV, which not only has a speaker and a microphone, but also has a camera at its front end, so that it can record the video of the fallen person and the scene. Although in the present embodiment, the smart home appliance is a smart TV, this is not a limitation of the present invention. Without departing from the principle of the present invention, in other embodiments, it can also be a smart phone or a smart tablet, and the smart phone and the smart tablet are fixed indoors so that they can record videos at any time.

[0055] The smart home system is connected to the server through network communication. The server is the hospital's backend server. The server can contact the hospital doctors, that is, it plays the role of information transmission. The server can also process the data; specifically, it can analyze and process the data.

[0056] Although the smart home appliance in this embodiment is only used to obtain live video and patient video, and does not process the video to obtain other physiological indicators, this is not a limitation of the present invention. Without departing from the principle of the present invention, in other embodiments, the patient's physiological indicators can be obtained based on the patient's video, and specifically, the server can perform data processing to obtain the physiological indicators. Specifically, the physiological indicators can be obtained based on the patient's facial video.

[0057] Specifically, the facial video is input into the MTTS-CAN multi-task network model to calculate the heart rate and respiratory rate. The calculation is performed through the following steps: the frames of the facial video and the differential normalization results between frames are input into the MTTS-CAN multi-task network model, and the signal curves of the heart rate and respiratory rate are output; the signal is canceled for detrending, filtering, and spectrum calculation; the heart rate and respiratory rate are calculated according to the frequency corresponding to the maximum value of the spectrum.

[0058] Acquiring the heart rate variability specifically includes: the server uses scipy to perform peak detection on the heart rate signal curve; according to the corresponding position of the peak, a sequence consisting of the time differences of all adjacent peak points is obtained; and the standard deviation of the sequence is calculated to obtain the heart rate variability.

[0059] The server can also obtain blood oxygen saturation based on the facial video. Specifically, blood oxygen saturation SPO 2 The calculation formula is as follows:

[0060]

[0061] Among them, A and B are empirical constants, and the R value is calculated from the red and blue channel values ​​of the ROI. The calculation formula is:

[0062]

[0063] Among them, ROI is obtained according to the facial video, I AC λ1 and I AC λ2 They refer to the standard deviation of the red and blue channel signals, respectively. DC λ1 and I DC λ2 are the average values ​​of the red and blue channel signals respectively.

[0064] The region of interest ROI is obtained in the following manner: all key points of the face are detected in the facial video, and the region of interest ROI is obtained according to the key points. The specific method of obtaining the ROI is prior art and will not be described in detail in this embodiment.

[0065] After the first aid device detects that a person has fallen, it can call for help from the hospital through the smart home system, specifically from the server. And after the person falls, the smart home system can control the camera of the smart home appliance to turn on (of course, the camera of the smart home appliance can also be turned on all the time, or turned on according to other instructions), so that the smart home appliance can record the scene and the patient's video, and transmit the recorded video to the smart home system, and then transmit it to the server by the smart home system. The server can contact the hospital doctor according to the call for help information, and transmit the scene video and the video of the fallen person to the hospital doctor at the same time. At the same time, it can also process the patient's video to obtain physiological indicators, and transmit the physiological indicators to the hospital doctor. The hospital doctor can obtain the condition of the fallen person based on the video of the fallen person, the scene video and the audio transmitted on the scene. The hospital doctor guides the family members to rescue the fallen person based on the condition. And give corresponding rescue suggestions, such as timely sending to the hospital, lying flat, diet and medication. So that patients can get rescue in time to avoid rapid deterioration of the disease or even death.

[0066] Regarding physiological indicators, it should be noted that although the server is used to calculate and obtain physiological indicators in this embodiment, this is not a limitation of the present invention. Without departing from the principles of the present invention, in other embodiments, those skilled in the art may also choose to have smart appliances or other components of the smart home system calculate and obtain physiological indicators based on facial videos.

[0067] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
