Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of paper diapers, and in particular to a urine wetness automatic alarm method, device, system and storage medium. BACKGROUND

[0002] When taking care of or carrying an infant or an old person for a long journey, a paper diaper is generally worn by the infant or the old person to absorb urine when the infant or the old person involuntarily excretes.

[0003] In the related art, a urine display strip is arranged on the paper diaper, the urine display strip is yellow when the paper diaper does not absorb urine, and the display strip is blue after the paper diaper absorbs urine, and the longer the length of the blue display strip, the more urine is absorbed. The caregiver needs to regularly check the urine display strip of the paper diaper according to the care experience of the infant or the old person.

[0004] In view of the related art, when the infant or the old person involuntarily excretes, it is difficult for the caregiver to regularly check the paper diaper according to the care experience, so that the caregiver cannot know the use of the paper diaper, which is not conducive to timely replacement of the paper diaper, and brings inconvenience to the infant or the old person. SUMMARY

[0005] In order to facilitate the caregiver to know the use of the paper diaper in time and replace the paper diaper, the present application provides a urine wetness automatic alarm method, system, intelligent terminal and storage medium.

[0006] In a first aspect, the present application provides a urine wetness automatic alarm method, which adopts the following technical solution:

[0007] A urine wetness automatic alarm method, comprising:

[0008] obtaining an indoor image of a preset indoor area;

[0009] comparing and analyzing the indoor image and a preset personnel paper diaper wearing feature to determine whether the indoor personnel wearing feature is consistent with the preset personnel paper diaper wearing feature;

[0010] if the indoor personnel wearing feature is inconsistent with the preset personnel paper diaper wearing feature, issuing a no wearing prompt;

[0011] if the indoor personnel wearing feature is consistent with the preset personnel paper diaper wearing feature, obtaining a paper diaper surface image of a preset wearing area of the personnel;

[0012] comparing and analyzing the paper diaper surface image and a preset paper diaper water absorption discoloration feature to determine whether to issue a replacement prompt information or a no replacement prompt information.

[0013] By adopting the technical scheme, the personnel in the nursing room are analyzed in terms of wearing features to find the personnel wearing diapers, and the diaper surface image is analyzed to determine whether the diaper discolors due to wetting, so that the nursing personnel do not need to regularly observe the diaper, and the diaper can be replaced in time according to the replacement prompt information.

[0014] Optionally, when the no wearing prompt is sent, the method further comprises:

[0015] The indoor image and the human body features are compared and analyzed to determine the personnel posture of the personnel in the room;

[0016] The personnel posture and the preset posture of the personnel to be nursed are compared to determine whether the personnel posture is consistent with the preset posture of the personnel to be nursed;

[0017] If the personnel posture is not consistent with the preset posture of the personnel to be nursed, the personnel corresponding to the personnel posture are marked as non-wearing personnel;

[0018] If the personnel posture is consistent with the preset posture of the personnel to be nursed, the personnel corresponding to the personnel posture are marked as wearing personnel, and an infrared sensing image of a preset wearing area of the wearing personnel is acquired;

[0019] The infrared sensing image is compared with a preset wet infrared feature to determine whether to send a replacement prompt information or a no-replacement prompt information.

[0020] By adopting the technical scheme, when the personnel in the room cannot be detected in terms of wearing features, the personnel posture is analyzed to identify the personnel who actually wear diapers but are blocked by loose clothes, and an infrared sensing image of a wearing area of the wearing personnel is acquired, so that whether the wearing personnel wet the diaper is analyzed through infrared thermal imaging, and a corresponding replacement prompt information is sent to the nursing personnel in time to determine whether the diaper needs to be replaced.

[0021] Optionally, when the infrared sensing image and the preset wet infrared feature are compared and analyzed, the method further comprises:

[0022] The infrared sensing image and a preset temperature change feature are compared and analyzed to determine a temperature rise area in the infrared sensing image and acquire a temperature rise time;

[0023] The temperature rise area and a preset reference area are compared and analyzed to determine an area increase of the area corresponding to the temperature rise area;

[0024] The area increase and the temperature rise time are analyzed to determine a wetting ratio;

[0025] The wet ratio is compared with the preset replacement wet ratio to determine whether the wet ratio value is less than the preset replacement ratio value;

[0026] If the wet ratio value is less than the preset replacement ratio value, a no-replacement prompt information is sent out;

[0027] If the wet ratio value is equal to or greater than the preset replacement ratio value, a replacement prompt information is sent out.

[0028] By adopting the above technical solution, when the wearer urinates in the diaper, the temperature rise area caused by the wet diaper is analyzed to determine whether the wet ratio value reaches the replacement ratio value within the temperature rise time, so that the diaper can further absorb liquid before prompting replacement, and the wearer will not feel uncomfortable.

[0029] Optionally, when the wet ratio value is less than the preset replacement ratio value, the method further comprises:

[0030] The body feature of the wearer is compared and analyzed with the preset gender feature to determine the gender of the wearer;

[0031] The gender of the wearer is matched and analyzed based on the preset optimal detection position to determine the optimal detection position of different genders of the wearer, and the wearing image of the wearer is obtained;

[0032] The optimal detection position is compared and analyzed based on the optimal detection position and the wearing image to determine whether the optimal detection position is blocked;

[0033] When the optimal detection position is blocked, the humidity detection value of the diaper is obtained;

[0034] The humidity detection value is compared and analyzed with the preset replacement humidity value to determine whether the humidity detection value is less than the preset replacement humidity value;

[0035] When the humidity detection value is equal to or greater than the preset replacement humidity value, a replacement prompt information is sent out.

[0036] By adopting the above technical solution, the optimal detection position of different genders of the wearer when the diaper is wet is determined, so that the humidity detection value at the optimal detection position is obtained for analysis, a more accurate wet diaper condition can be obtained, and the replacement prompt information is sent out when the humidity detection value at the optimal detection position is equal to or greater than the replacement humidity value.

[0037] Optionally, when the optimal detection position is blocked, the method further comprises:

[0038] The camera position of the preset camera device and the personnel area image of the wearer are obtained;

[0039] analyzing the personnel area image and the preset occlusion feature to determine an occlusion area and a non-occlusion area;

[0040] analyzing the non-occlusion area and a preset movement track of the camera to determine a non-occlusion shooting position on the preset movement track;

[0041] analyzing the non-occlusion shooting position, the camera shooting position and the preset movement track of the camera to determine a minimum movement path on the preset movement track;

[0042] indicating the preset movement device on the preset shooting device to move to the non-occlusion shooting position along the minimum movement path.

[0043] By using the above technical solution, when the optimal detection position of the diaper is occluded, the shooting position capable of shooting the optimal detection position is determined by analyzing the preset movement track of the camera, and the minimum movement path is found out by analyzing the movement track and the camera shooting position, and the movement device is controlled to move the camera along the minimum movement path, thereby saving the time consumed in the movement process, and the image of the optimal detection position can be shot, so that the infrared sensing image and the diaper surface image are analyzed to determine the wetness of the diaper, which helps to improve the analysis accuracy of the wetness of the diaper.

[0044] Optionally, before the wearing image of the wearer is acquired, the method further comprises:

[0045] acquiring the area light intensity of the area where the wearer is located;

[0046] comparing the light intensity with a preset reference light intensity to determine whether the light intensity is less than the preset reference light intensity;

[0047] if the light intensity is equal to or greater than the preset reference light intensity, an instruction for acquiring the wearing image is issued;

[0048] if the light intensity is less than the preset reference light intensity, the infrared sensing image is compared with a preset wearer infrared sensing contour feature to determine a wearer contour posture of the wearer;

[0049] the wearer contour posture is compared with a preset sleep posture to determine whether the wearer contour posture fits the preset sleep posture;

[0050] if the wearer contour posture fits the preset sleep posture, a wetness detection value of the diaper is acquired;

[0051] if the wearer contour posture does not fit the preset sleep posture, the preset lighting device is instructed to be turned on to a light intensity equal to or greater than the preset reference light intensity, and an instruction for acquiring the wearing image is issued.

[0052] By adopting the technical scheme, before the wearing image is shot, the light brightness of the area where the wearer is located is analyzed to know whether the light brightness meets the requirement of shooting a clear image, and further analysis is made on whether the wearer is in a sleep state when the light brightness is insufficient, if not, the light is controlled to be turned on by the lighting device to improve the light brightness of the area where the wearer is located, so that a clear wearing image is obtained conveniently, and when the wearer is in a sleep state, the humidity detection value is obtained to analyze the wetness of the diaper, and the sleep of the wearer is not affected.

[0053] Optionally, when the humidity detection value of the diaper is obtained, the method further comprises:

[0054] obtaining a detection position mark of the preset humidity detection device;

[0055] comparing and analyzing the detection position mark and the preset inside position mark to determine whether the detection position mark is the same as the preset inside position mark;

[0056] if the detection position mark is the same as the preset inside position mark, comparing the humidity detection value with a preset replacement humidity value to determine whether to send a no-replacement prompt information or a replacement prompt information;

[0057] if the detection position mark is different from the preset inside position mark, comparing the humidity detection value with a preset non-influence humidity value;

[0058] if the humidity detection value is less than the preset non-influence humidity value, the no-replacement prompt information is sent;

[0059] if the humidity detection value is equal to or greater than the preset non-influence humidity value, the replacement prompt information is sent.

[0060] By adopting the technical scheme, the detection position mark of the humidity detection device is analyzed to determine whether the humidity detection device is on the inside or the outside, so as to distinguish the situation that the diaper is accidentally wetted by external liquid, and further analyze the humidity detection value of the accidentally wetted diaper, when the humidity detection value is greater than or equal to the preset non-influence humidity value, a replacement prompt is made, so as to avoid that the humidity value of the wetted outside of the diaper is too large to affect the wearing comfort of the wearer.

[0062] An automatic diaper wetness alarm device comprises:

[0063] a humidity detection device, which is detachably embedded in a diaper, is used for detecting a humidity detection value of the diaper;

[0064] The alarm device is connected with the humidity detection device through a signal line, and is used for receiving the humidity detection value and sending a replacement prompt information.

[0065] By using the above technical solution, the diaper is detected by the humidity detection device, and the obtained humidity detection value is output to the alarm device. After receiving the humidity detection value, the alarm device sends a replacement prompt information to alarm. Therefore, the caregiver can replace the diaper according to the replacement prompt information, and the caregiver needs to check the diaper.

[0066] In a third aspect, the application provides an automatic urine wetness alarm system, which adopts the following technical solution:

[0071] By using the above technical solution, the color change characteristics of the diaper caused by urine wetting are analyzed by using the smart terminal, and a replacement prompt information is sent in time to inform the caregiver to replace the diaper. The caregiver does not need to observe the urine wetting condition of the diaper frequently, which helps to reduce the care workload of the caregiver and improve the timeliness of replacing the diaper.

[0072] In a fourth aspect, the application provides a computer storage medium, which can store a corresponding program and has the characteristics that the caregiver can know the use condition of the diaper in time and replace the diaper. The following technical solution is adopted:

[0073] A computer readable storage medium stores a computer program that can be loaded and executed by a processor to implement any one of the automatic urine wetness alarm device methods.

[0074] By using the above technical solution, the computer program of the automatic urine wetness alarm device method is stored in the storage medium. By loading the computer program, the color change characteristics of the diaper caused by urine wetting are analyzed, and a replacement prompt information is sent in time to inform the caregiver to replace the diaper. The caregiver does not need to observe the urine wetting condition of the diaper frequently, which helps to reduce the care workload of the caregiver and improve the timeliness of replacing the diaper.

[0088] In order to make the purpose, technical scheme and advantages of the present application more clear, the following further describes the present application in combination with the accompanying drawings and examples. Figures 1-8 It should be understood that the specific examples described herein are intended to explain the present application, but not to limit the present application.

[0089] The following further describes the embodiments of the present application in combination with the accompanying drawings of the specification.

[0090] The embodiments of the present application disclose a urine wetness automatic alarm method, which obtains an indoor image, analyzes a personnel wearing feature in the indoor image to determine a personnel meeting a diaper wearing feature, further obtains a diaper surface image of the personnel meeting the diaper wearing feature, analyzes and determines according to the diaper surface image to determine whether the diaper changes color due to absorbing urine wetness, and sends a replacement prompt information to prompt a caretaker to replace the diaper in time, without the caretaker needing to regularly check, which can reduce the labor of the caretaker and help replace the diaper in time.

[0091] Referring to Figure 1 , the method flow of the urine wetness automatic alarm method includes the following steps:

[0092] Step S100: Obtain an indoor image of a preset indoor area;

[0093] The indoor image is a wide-angle image of a care indoor, which is obtained by presetting a camera to be installed in the care indoor to take a picture. When taking a picture, the image of the personnel on the care bed and in the indoor can be taken, and the personnel to be cared for include infants, children and the elderly and other personnel needing to be cared for.

[0094] Step S101: Compare and analyze the indoor image and a preset personnel diaper wearing feature to determine whether the wearing feature of the indoor personnel is consistent with the preset personnel diaper wearing feature;

[0095] The diaper wearing feature is an image feature of the personnel when wearing a diaper, which is obtained by collecting features of different types of diaper wearing images by a worker to establish a wearing recognition database. When the indoor image is input into the wearing recognition database, whether the personnel in the indoor image wears a diaper can be recognized, so that whether the indoor personnel wears a diaper can be determined, and the caretaker and the cared-for personnel can be distinguished.

[0096] Step S102: If the indoor personnel wearing feature is inconsistent with the preset personnel diaper wearing feature, a no wearing prompt is sent.

[0097] If the indoor personnel wearing feature is inconsistent with the preset personnel diaper wearing feature, it indicates that the personnel is not wearing a diaper and is a caregiver rather than a cared-for person. At this time, a no wearing prompt instruction is issued, and based on the no wearing prompt instruction, the indoor image is continuously identified and judged.

[0098] Step S103: If the indoor personnel wearing feature is consistent with the preset personnel diaper wearing feature, a diaper surface image of the preset wearing area of the personnel is acquired.

[0099] If the indoor personnel wearing feature is consistent with the preset personnel diaper wearing feature, it indicates that there is a cared-for person in the indoor, and further urine wetting monitoring of the cared-for person is needed. The wearing area is the body position of the caregiver when wearing the diaper. The wearing image can be obtained by image interception or image magnification and then shooting by the camera. The image obtained by shooting is defined as the diaper surface image.

[0100] Step S104: The diaper surface image and the preset diaper water absorption color change feature are compared and analyzed to determine whether to issue a replacement prompt information or a no replacement prompt information.

[0101] The diaper water absorption color change feature is the feature of the diaper turning blue after absorbing urine. The image of the diaper when wetting is captured by the staff, and the color change at different positions is imaged to establish a diaper wetting change feature database. The change image features of different areas of the diaper when wetting are stored in the database. When the diaper is input into the diaper wetting change feature database, whether the diaper surface image has a wetting feature can be identified.

[0102] If the diaper surface has a wetting feature, it indicates that the personnel wearing the diaper has wetted the diaper and caused the diaper to change color. The caregiver needs to replace the diaper in time, and a replacement prompt information is issued for prompt, so that the caregiver can replace the diaper in time.

[0103] If the diaper surface does not have a wetting feature, it indicates that the cared-for person does not need to replace the diaper. At this time, a no replacement prompt information is issued. In this embodiment, the replacement prompt information or the no replacement prompt information is notified by a bell sound.

[0104] Referring to Figure 2 , when the no wearing prompt is issued, it further includes:

[0105] Step S200: Comparing and analyzing the indoor image and the human feature to determine the personnel posture of the indoor personnel.

[0106] When a "no diaper wearing" warning is issued, it indicates that no one in the room is wearing a diaper. This could be because the person wearing a diaper is wearing loose clothing or is covered by a blanket, making it impossible to identify the diaper wearing feature from the image. In this case, further judgment is needed through other methods. Human body features are the outline features of the human body. By comparing the indoor image with human body features, the human body features of the corresponding person in the indoor image can be obtained and defined as the person's body posture.

[0107] Step S201: Compare the person's body shape with the preset body shape of the person to be cared for to determine whether the person's body shape is consistent with the preset body shape of the person to be cared for;

[0108] The body posture of the person to be cared for is the physical characteristics of infants and the elderly. This is determined by staff extracting image features from a large number of infants and the elderly, and establishing a body posture database of the person to be cared for. When the body posture of a person is input into the body posture database, it can be identified and compared to see if the body posture of the person is consistent with that of the person who opened the pot.

[0109] Step S202: If the body shape of the person is inconsistent with the preset body shape of the person to be cared for, then mark the person corresponding to the body shape as a non-wearing person;

[0110] If the body posture of the person being cared for is inconsistent with the preset body posture of the person to be cared for, it means that there is no person to be cared for in the room at this time. In this case, the person corresponding to the body posture is marked and defined as an unwearing person.

[0111] Step S203: If the body shape of the person is consistent with the body shape of the person to be cared for, then mark the person corresponding to the body shape as the person wearing the garment, and obtain the infrared sensing image of the preset wearing area of ​​the person wearing the garment.

[0112] If a person's body shape matches the pre-defined body shape of a person needing care, it indicates the presence of such a person in the room. However, they cannot be identified by comparing their diaper-wearing characteristics, as the diaper is obscured. Even though the person's body shape is typically that of an infant or elderly person, they may be wearing a diaper. In this case, the person is marked and defined as the diaper wearer. An infrared thermal imaging device is then used to capture the diaper-wearing area, defining it as an infrared sensor image for further analysis.

[0113] Step S204: Based on the comparison and analysis of the infrared sensor image and the preset infrared characteristics of urine, determine whether to issue a replacement prompt or an information indicating that replacement is not required.

[0114] The urine wetting infrared feature is an infrared thermal imaging feature generated when the diaper is wetted. Because the temperature at the wetted area is higher, the infrared sensing image at the wetted area is different in color from the surrounding infrared sensing image. By comparing the infrared sensing image and the urine wetting infrared feature, it can be determined whether the infrared sensing image has the urine wetting infrared feature. If the infrared sensing image has the urine wetting infrared feature, it indicates that the person to be cared for has urinated and wetted the diaper, and the diaper needs to be changed. At this time, a change prompt information is sent. If the infrared sensing image does not have the urine wetting infrared feature, it indicates that the person to be cared for has not wetted the diaper. At this time, a no change prompt information is sent.

[0115] With reference to Figure 3 , the comparison and analysis of the infrared sensing image and the preset urine wetting infrared feature further includes:

[0116] Step S300: Comparing and analyzing the infrared sensing image and the preset temperature change feature to determine a temperature rise area in the infrared sensing image and to obtain a temperature rise time;

[0117] The temperature change feature is a temperature thermal imaging color change feature caused by the continuous temperature rise at the wetted area when the person to be cared for urinates. For example, blue represents a lower temperature in the thermal imaging area, and the deeper the red color, the higher the temperature. When the thermal imaging color of the wetted area gradually changes from light to red, it indicates that the area is in the wetted area. The area is defined as a temperature rise area. The temperature rise time is timed when the urine wetting infrared feature is detected, and the timing stops when the urine wetting infrared feature no longer changes. The timing time is defined as the temperature rise time.

[0118] Step S301: Comparing and analyzing the temperature rise area and the preset reference area to determine an area increase area corresponding to the temperature rise area;

[0119] The reference area is the thermal imaging area of the diaper when no wetting occurs. Comparing the temperature rise area and the reference area can obtain the increase area of the temperature rise area, and the increase area is defined as the area increase area.

[0120] Step S302: Analyzing the area increase area and the temperature rise time to determine a wetting ratio;

[0121] By taking the area increase area and the rise time as the reference parameters of the xy coordinate axis, and establishing a rectangular coordinate system, the area increase area continuously rises within the temperature rise time as the time increases, and a corresponding coordinate curve is formed. By drawing a perpendicular line from the end of the coordinate curve to the x coordinate axis, the area corresponding to the coordinate curve can be obtained, and the area is defined as the wetting ratio.

[0122] Step S303: comparing the urine wetness ratio with the preset replacement urine wetness ratio to determine whether the urine wetness ratio value is less than the preset replacement ratio value;

[0123] The replacement ratio is the ratio at which the urine wetness ratio reaches a certain ratio, which will cause an impact on the wearer of the diaper. By comparing the urine wetness ratio with the replacement urine wetness ratio, the size relationship between the two can be determined, so as to make further control and analysis.

[0124] Step S304: if the urine wetness ratio value is less than the preset replacement ratio value, a no-replacement prompt information is sent out;

[0125] If the urine wetness ratio value is less than the preset replacement ratio value, it means that the urine wetness ratio caused by the diaper wetting of the person to be cared for is relatively low, and the diaper does not need to be replaced immediately. Therefore, a no-replacement prompt information is sent out.

[0126] Step S305: if the urine wetness ratio value is equal to or greater than the preset replacement ratio value, a replacement prompt information is sent out.

[0127] If the urine wetness ratio value is equal to or greater than the preset replacement ratio value, it means that the proportion of the diaper wetting by the person to be cared for is relatively large. If the diaper is continued to be worn, it is easy to cause the skin of the person to be cared for to be red and swollen due to long-term soaking. Therefore, the diaper needs to be replaced, and a replacement prompt information is sent out to prompt the caregiver to replace the diaper.

[0128] Reference Figure 4 When the urine wetness ratio value is less than the preset replacement ratio value, it further includes:

[0129] Step S400: comparing and analyzing the body posture feature of the wearer with the preset gender feature to determine the gender of the wearer.

[0130] The gender feature is the body posture feature corresponding to different genders. For example, by analyzing the Adam's apple feature in the body posture feature, it can be analyzed whether the corresponding person is male or female. The purpose of analyzing the gender of the wearer is to make further control on the urine wetness detection.

[0131] Before analyzing the body posture feature, the body posture feature is compared with the preset body posture of infants and young children. If the body posture feature is inconsistent with the preset body posture of infants and young children, the body posture feature of the wearer is compared and analyzed with the preset gender feature to determine the gender of the wearer. If the body posture feature is consistent with the preset body posture of infants and young children, the gender information of the person is obtained, and a gender prompt is sent out according to the gender information to determine the gender of the wearer.

[0132] Step S401: Based on the gender of the wearer and the preset optimal detection position, a matching analysis is performed to determine the optimal detection position for different genders of the wearer, and the wearing image of the wearer is obtained;

[0133] The optimal detection position is the optimal position for urine wetness detection corresponding to the gender of the person. By analyzing the first wet position caused by urine wetness of men and women, the optimal detection position is defined. For example, men are prone to cause urine wetness on the front side of the body first, while women are prone to cause urine wetness on the lower back of the body first. The wearing image is the image of the diaper when it is worn, which is obtained by a pre-installed camera.

[0134] Step S402: Based on the optimal detection position and the wearing image, a comparison analysis is performed to determine whether the optimal detection position is blocked;

[0135] In the analysis, the optimal detection position in the wearing image is compared with the preset diaper unblocked feature to determine whether the image corresponding to the optimal detection position of the diaper is consistent with the diaper unblocked feature. If it is consistent, it means that the optimal detection position is not blocked. If it is not consistent, it means that the optimal detection position of the diaper is blocked.

[0136] Step S403: When the optimal detection position is blocked, the wetness detection value of the diaper is obtained;

[0137] When the optimal detection position is blocked, it means that the diaper surface image obtained at this time as the basis for judging whether it is wet is a relatively lagging judgment result. The caregiver may have already wetted the diaper to a wetness ratio value that exceeds the replacement wetness ratio value. Therefore, when the optimal detection position is blocked, the wetness of the diaper needs to be detected directly. The wetness can be detected by clamping a humidity sensor on the diaper. The humidity sensor uses a small micro sensor that does not affect the wearing of the diaper. The detection positions are arranged at intervals. The detected value is the humidity detection value.

[0138] Step S404: According to the humidity detection value and the preset replacement humidity value, a comparison analysis is performed to determine whether the humidity detection value is less than the preset replacement humidity value;

[0139] The replacement humidity detection value is the humidity value when the diaper needs to be replaced. By comparing the humidity detection value and the replacement humidity value, the humidity detection value of the diaper can be obtained to inform the staff in a timely manner whether the diaper needs to be replaced.

[0140] Step S405: When the humidity detection value is equal to or greater than the preset replacement humidity value, a replacement prompt information is sent.

[0141] The humidity detection value is equal to or greater than the preset replacement humidity value, indicating that the humidity value of the diaper is high, which is easy to cause harm to the skin of the person to be cared for. At this time, a replacement prompt information is sent out to prompt the caregiver to replace the diaper.

[0142] If the humidity detection value is less than the preset replacement humidity value, it indicates that only a small area of the diaper is wet at this time, which will not cause discomfort to the skin of the person to be cared for. At this time, a no-replacement prompt is sent out to reduce the loss caused by replacement.

[0143] Reference Figure 5 When the optimal detection position is blocked, further comprising:

[0144] Step S500: obtaining a preset camera position of a camera and a personnel area image of a wearer;

[0145] The camera position is the installation position of the camera, which is determined by the drawing of the installation construction. The personnel area image is the environmental image of the wearer on the side of the camera in the indoor image captured by the camera at the current position.

[0146] Step S501: analyzing the personnel area image and the preset blocking feature to determine a blocking area and a non-blocking area;

[0147] The preset blocking feature is the bed edge protrusion of the care bed or the folding table board placed on the bed in the care room, etc. By comparing and analyzing the personnel area image and the blocking feature, it is determined whether there is a blocking object in the personnel area image that blocks the wearing area of the personnel. The area that forms the blocking is defined as the blocking area, and the area that does not block the wearing area is defined as the non-blocking area. The blocking area and the non-blocking area are marked to facilitate further control of the subsequent camera adjustment.

[0148] Step S502: analyzing the non-blocking area and the preset movement trajectory of the preset camera to determine a non-blocking shooting position on the preset movement trajectory;

[0149] The preset movement trajectory is the trajectory that the camera can move when shooting. By setting a slide rail and forming a transmission connection between the camera and the slide rail, different shooting angles in different directions can be obtained when the camera moves along the movement trajectory on the slide rail, so as to obtain different monitoring angles of the wearer. By establishing a shooting angle database, different shooting directions of the camera on the preset movement trajectory are stored in the data. When the position of the blocking feature is input, the shooting position that is not blocked can be output. The position is defined as the non-blocking shooting position. The number of non-blocking shooting positions may be one or more.

[0150] Step S503: analyzing based on the unobstructed shooting position, the camera shooting position and the preset moving track to determine the minimum moving path on the preset moving track;

[0151] The minimum moving path is the shortest path of the camera moving to the unobstructed shooting position along the preset moving track. By connecting the camera shooting position and the unobstructed shooting position along the moving track, a plurality of different moving distances between the shooting position and the unobstructed shooting position are determined, and the plurality of different moving distances are screened to screen the unobstructed shooting position with the smallest moving distance, and mark it as the nearest adjustment position. The track moving to the nearest adjustment position is defined as the minimum moving path.

[0152] Step S504: instructing the moving device preset on the preset shooting device to move to the unobstructed shooting position along the minimum moving path.

[0153] The moving device is a transmission mechanism arranged on the slide rail and connected with the slide rail in transmission. The transmission mechanism and the slide rail can be engaged in transmission through gears and driven by a servo motor to drive the moving device to move the camera to the unobstructed shooting position, so that the camera can obtain the unobstructed personnel area image.

[0154] Referring to Figure 6 , before obtaining the wearing image of the wearer, further comprising:

[0155] Step S600: obtaining the area light illumination of the area where the wearer is located;

[0156] The area light illumination is the light illumination value of the area where the personnel is located, which is determined by pre-installing a light intensity tester to detect.

[0157] Step S601: comparing the light illumination with the preset reference light illumination to determine whether the light illumination is less than the preset reference light illumination;

[0158] The light illumination value corresponding to the reference light illumination is the light illumination that can obtain a clear image when image shooting is performed. The specific brightness value is set by the staff according to the actual test result, and it is determined whether the light illumination value is less than the reference light illumination.

[0159] Step S602: if the light illumination is equal to or greater than the preset reference light illumination, issuing a wearing image acquisition instruction;

[0160] The light illumination is equal to or greater than the preset reference light illumination, which means that the light illumination meets the condition of shooting a clear image. At this time, the wearing image acquisition instruction is issued to instruct the camera to shoot the wearing image, so as to facilitate subsequent analysis of the wearing image.

[0161] Step S603: If the light illumination is less than the preset reference light illumination, the infrared sensing image is compared and analyzed with the preset personnel infrared sensing contour feature to determine the personnel contour posture of the wearer;

[0162] The light illumination being less than the preset reference light illumination indicates that the light illumination is insufficient, and the condition for shooting a clear image is not met. Therefore, the light illumination needs to be adjusted. Before the adjustment, the activity of the personnel is analyzed. The personnel infrared sensing contour feature is the body contour feature obtained by infrared thermal imaging of the human body. By comparing the infrared sensing image with the preset personnel infrared sensing contour feature, the body contour feature of the wearer can be obtained. The feature is defined as the personnel contour posture.

[0163] Step S604: The personnel contour posture is compared and analyzed with the preset sleep posture to determine whether the personnel contour posture matches the preset sleep posture;

[0164] The sleep posture is the human body contour posture feature of the personnel when sleeping. The sleep postures of different people when sleeping are collected and recorded by the working personnel, and the corresponding contour features are extracted. The extracted contour features are used to establish a contour feature database. The personnel contour posture is input into the database, and whether the personnel contour posture matches the feature corresponding to the sleep posture can be compared, so that corresponding control adjustment can be made according to the analysis result.

[0165] Step S605: If the personnel contour posture matches the preset sleep posture, the wetness detection value of the diaper is obtained;

[0166] The personnel contour posture matching the preset sleep posture indicates that the wearer of the diaper is in a sleeping state at this time. If the light illumination is adjusted, it will affect the sleep. Therefore, the light illumination cannot be adjusted, and the corresponding wearing image is obtained to determine the wetness condition. Then, the wetness detection value of the wetness detection sensor is obtained, and the wetness detection value and the replacement wetness value are analyzed to determine whether to send a replacement prompt information.

[0167] Step S606: If the personnel contour posture does not match the preset sleep posture, the preset lighting device is instructed to be turned on until the light illumination is equal to or greater than the preset reference light illumination, and a wearing image acquisition instruction is sent.

[0168] The personnel contour posture not matching the preset sleep posture indicates that the wearer of the diaper is not in a state of needing to sleep at this time. Therefore, at this time, the light illumination increase prompt information can be sent, the light illumination is adjusted according to the light illumination prompt information, and when the light illumination reaches the reference light illumination, the adjustment is stopped and the wearing image acquisition instruction is sent to instruct the camera to shoot the wearing image.

[0169] Referring toFigure 7 , when acquiring the wetness detection value of the diaper, further comprising:

[0170] Step S700: acquiring a detection position mark of the preset wetness detection device;

[0171] The wetness detection device is a humidity sensor for detecting humidity, and the detection position mark is a corresponding mark number of the wetness detection sensor. The detection device detects the inner side and the outer side of the diaper respectively, and the sensors on the inner side and the outer side have different mark numbers.

[0172] Step S701: comparing and analyzing the detection position mark and the preset inner side position mark to determine whether the detection position mark is the same as the preset inner side position mark;

[0173] The preset inner side mark is the mark number of the humidity sensor on the inner side. By comparing the number corresponding to the detection position mark, it can be known whether the detection position mark is the same as the number of the inner side position mark.

[0174] Step S702: if the detection position mark is the same as the preset inner side position mark, comparing the wetness detection value with the preset replacement humidity value to determine whether to issue a no replacement prompt information or a replacement prompt information;

[0175] The detection position mark is the same as the preset inner side position mark, which means that the detected wetness detection value is caused by urine wetness. At this time, the wetness detection value and the preset replacement humidity value can be directly compared. If the wetness detection value is equal to or greater than the replacement humidity value, a replacement prompt information is issued. If the wetness detection value is less than the replacement humidity value, a no replacement prompt information is issued.

[0176] Step S703: if the detection position mark is different from the preset inner side position mark, comparing the wetness detection value with the preset non-impact humidity value;

[0177] The detection position mark is different from the preset inner side position mark, which means that the detected wetness detection value belongs to the humidity of the outer side of the diaper, which may be caused by the external water cup or other liquid mistakenly contacting the diaper. The non-impact humidity value is the humidity value when the liquid contacts the outer side of the diaper without affecting the wearing of the diaper. By comparing the wetness detection value with the preset non-impact humidity value, it can be known whether the diaper needs to be replaced.

[0178] Step S704: if the wetness detection value is less than the preset non-impact humidity value, issuing a no replacement prompt information;

[0179] The wetness detection value is less than the preset non-impact humidity value, which means that the liquid mistakenly contacting the outer side of the diaper does not affect the wearing of the diaper, so a no replacement prompt information is issued. The staff can wipe it dry with a water-absorbing paper or a paper towel.

[0180] Step S705: If the humidity detection value is equal to or greater than the preset non-impact humidity value, a replacement prompt information is sent out.

[0181] The humidity detection value equal to or greater than the preset non-impact humidity value indicates that the liquid touching the outside of the diaper has an impact on the normal wearing of the diaper, at this time, although there is no impact caused by urine wetting, the diaper needs to be replaced to avoid the impact of cold, and the replacement prompt information is sent out.
