Description

[0001] This invention patent application is a divisional application of the Chinese invention patent application with application date of April 2, 2019, application number 2019102626277, and application name “Indoor Care Assistance Method and System”. Technical Field

[0002] The present invention relates to the field of intelligent nursing technology, and in particular to an indoor nursing assistance method, system, device, computer equipment and computer-readable storage medium. Background Art

[0003] Elderly people are more likely to have physical emergencies in their daily lives than young people. Common emergencies include accidental falls, sudden physical discomfort or unspeakable pain that lead to difficulty in movement. If the above situations occur indoors, such as at home or in senior citizen apartments, and there is no one around, if there is some kind of auxiliary equipment that can detect the abnormal situation of the elderly's difficulty in movement, and immediately inform their family members or the staff of the custody service agency for verification and confirmation, and then provide timely assistance, it will greatly enhance the safety of the elderly living alone.

[0004] At present, the care technology used to help the elderly seek help in emergencies mainly includes wearable wireless devices, fixed or portable wireless emergency call (remote control) devices and indoor video monitoring, if we do not consider the professional equipment used in professional nursing places. However, today's lightweight wireless wearable devices such as bracelets cannot correctly identify whether the human body is in difficulty in movement. Instead, they rely on the user to perform emergency calls during use. In addition, the battery life is weak and needs to be taken off frequently for charging. It cannot guarantee that the elderly can wear them for a long time and perform emergency calls at any time. Wearable devices with certain care capabilities are large in size, which hinders physical activities and has many restrictions on user behavior. They are not suitable for a wide range of life scenarios. As for the elderly in emergencies, such as physical discomfort during bathing, difficulty in movement or even confusion, it is even more difficult to ask them to find a non-wearable fixed intercom or portable remote control to call for help. In addition, even if the indoor video monitoring method does not rely on real-time human observation in the future, but uses artificial intelligence to interpret and judge images, this method of monitoring all the life behaviors of the elderly all day long is obviously unethical and difficult to be accepted.

[0005] In summary, the various current indoor care assistance technologies have various shortcomings in the face of actual needs. Summary of the invention

[0045] In order to better understand the purpose, technical solution and technical effect of the present invention, the present invention is further explained below in conjunction with the accompanying drawings and embodiments. At the same time, it is stated that the embodiments described below are only used to explain the present invention and are not used to limit the present invention.

[0046] like Figure 1 As shown, it is a flow chart of the indoor nursing assistance method of embodiment 1, including steps S101 to S104:

[0047] S101, obtaining human body presentation information in each preset height interval;

[0048] The human body information refers to the intuitive information of the human body appearance or non-intuitive information such as human body infrared radiation that can be detected by electromagnetic waves. Preferably, the human body information is human body infrared radiation information, that is, human body activity information detected by passive infrared detection technology such as pyroelectric infrared sensor combined with optical lens such as Fresnel lens, such as curtain infrared probe.

[0049] Among them, the height in the preset height interval refers to the vertical height from the ground, and the preset height can be adjusted within the interval according to the specific height of the user. The following takes three preset height intervals as an example to explain the setting of the height interval, wherein the three preset height intervals include a first preset height interval, a second preset height interval, and a third preset height interval. The first preset height interval is 130 to 150 cm, the second preset height interval is 80 to 90 cm, and the third preset height interval is 10 to 20 cm. In this way, for a cared person whose height is less than 1.8 meters, when the cared person is within the detection range and is standing or walking, the human body presentation information of the cared person can be detected in the first preset height interval, the second preset height interval and the third preset height interval; when the cared person indoors is in a sitting position with both feet on the ground, such as sitting on a stool, sofa or toilet, the human body presentation information of the cared person can be detected in the second preset height interval and the third preset height interval (that is, both the upper body and the leg and foot movements will be detected); when the cared person indoors sits on a bed or a stool, sofa with both feet off the ground, the human body presentation information can only be detected in the second preset height interval; and if the cared person lies on his back / prone on the ground or sits on the ground with his head down, the human body presentation information of the cared person can only be detected in the third preset height interval; when the cared person is outside the effective detection range of the system or leaves the current care area indoors, the human body presentation information of the cared person cannot be detected in the first preset height interval, the second preset height interval and the third preset height interval. But what is special is that if the system uses passive infrared detection technology to obtain human body presence information, even if the person being cared for is still in the care area (effective detection range), the body behavior may change from obvious activity to stillness or inconspicuous activity (i.e. the activity amplitude is lower than the detection capability of the infrared probe) for a period of time, which may cause the human body presence information during this period to be zero. Obviously, this does not mean that the person being cared for has left the effective care area.

[0050] Optionally, the preset heights can be simplified according to the characteristics of human activities in the guarded area. For example, if the guarded area is a bathroom or a kitchen, since people normally do not lie down to rest there, it is sufficient to set the second preset height interval and the third preset height interval to promptly detect whether human behavior is abnormal.

[0051] S102, obtaining presentation information code according to the human body presentation information in each preset height interval;

[0052] In one embodiment, when human body presentation information appears in each preset height interval, presentation information code is obtained according to the human body presentation information. That is, when human body presentation information appears in the preset height interval, the human body presentation information is recorded, and the presentation information code is obtained by combining the recorded human body presentation information in each preset height zone.

[0053] In one embodiment, the human body presentation information at different height intervals at the same address is represented by numbers or characters, and the character combination (code combination) formed by arranging in the order of each height interval is the presentation information code. In an optional implementation, the presentation information code is to represent the human body presentation information in each preset height interval in binary, and then arrange it in the order of each preset height to form a binary digital string.

[0054] Optionally, the process of obtaining the information code presented at a certain address according to the human body presentation information within the preset height intervals includes the steps of: obtaining the address information; arranging and combining the address information and the human body presentation information to obtain the presentation information code.

[0055] That is, the human body presentation information and the address information are superimposed and arranged, and the generated presentation information code includes the address feature. Taking the above-mentioned first preset height interval, second preset height interval and third preset height interval as examples, the presentation information coding is explained: let the human body presentation information in the first preset height interval be P1, the human body presentation information in the second preset height interval be P2, and the human body presentation information in the third preset height interval be P3. Optionally, the specific binary representation is: if the human body presentation information is detected in the first preset height interval, P1=1, and if the human body presentation information is not detected, P1=0; similarly, P2=1 or 0, P3=1 or 0. Then the human body presentation information at three heights is arranged in the preset height order as: P1+P2+P3, and the following coding results will appear corresponding to the human body behavior described as an example in the above step S101: when the cared person is standing on the ground or walking, P1+P2+P3=111; when the cared person sits on a bed, stool, sofa or toilet with his feet on the ground, P1+P2+P3=011; if the cared person falls to the ground, it must be P1+P2+P3=001. If the address location information of each care area is represented by letters such as A, B, C (of course, it can also be directly represented by numbers) and placed at the first place of the presentation information code, then when someone enters the originally unmanned area A, the presentation information code (string) generated in step S102 is (from A000 to) A111; if the person being cared for enters area C, such as the bathroom, from area A, first the code C111 is generated in step S102, and then A000 is generated (leaving A); if he sits on the toilet, the code C011 will appear; and if he falls to the ground accidentally while sitting on the toilet, the code C001 will be generated in S102, and so on.

[0056] Optionally, the human body presentation information within each preset height interval can be obtained in a non-continuous manner, that is, the human body presentation information within each preset height interval is obtained once every time period, and the obtained human body presentation information is successively combined with the address position information to obtain the presentation information code at the current address.

[0057] S103, recording the duration of the matching state between the presented information code and the target code and comparing it with the time threshold corresponding to the target code;

[0058] The so-called target code refers to a set of codes preset in the system, which can be obtained from the system through a matching method and are exactly the same as the external presentation information codes, and correspond one by one. All the codes that correspond one by one to the external presentation information codes constitute a target code set. Each target code in the set can reflect a possible (normal or abnormal) behavior posture of a human body in a certain place indoors, and the entire target code set reflects the possible behavior posture of a human body in various places indoors. Therefore, through a certain target code in this target code set, it is possible to know what kind of human behavior posture is represented by a certain presentation information code that matches it.

[0059] In an optional implementation, according to the corresponding relationship between the distribution of human body presentation information in vertical height and its behavior posture, a preset code set that uses the distribution of human body presentation information in vertical height to describe human body behavior posture can be pre-built in the system. If these preset codes and external presentation information codes use a completely consistent coding method and correspond to the same preset height intervals, as mentioned above, these preset codes can be used as target codes and correspond to each external presentation information code one by one. From this target code set, each target code and its represented data value can be obtained - the duration allowed for a certain human body behavior posture, that is, the time threshold (time threshold) corresponding to the target code.

[0060] The specific instructions are as follows:

[0061] 1. When a person sits, lies, stands, walks, etc. in a room, their postures will be distributed at different heights in the vertical direction.

[0062] For elderly people who are not physically disabled due to limb disability, unless they have severe hunchback, their daily indoor behavior posture (excluding dangerous behaviors such as using ordinary bathtubs, squatting toilets, and rolling and jumping) in the vertical direction clearly corresponds to the following heights:

[0063] 1. The posture of standing on the ground, moving and walking;

[0064] For example, if an elder is 1.5 meters tall, even if he hunches slightly, his height when standing or walking will not be less than 1.3 meters.

[0065] 2. The behavior and posture when sitting on a stool, sofa, bed or toilet;

[0066] Since the height of desks, dining tables and other countertops in the home environment is almost 0.8 meters, the sitting height of adults of all heights in front of these tables and countertops, whether they are eating, chatting or reading, even those who are buried in their desks, will be higher than 0.8 meters from the ground. When sitting in front of a table or countertop, even if the height is 1.4 meters, the height of the head from the ground will not be less than 0.8 meters when sitting on a stool, sofa, bed or toilet.

[0067] 3. Lying down on a bed or a sofa;

[0068] In an environment with normal furniture specifications, no matter how tall the elderly are, the height of their limbs from the ground will not be less than 0.5 meters when they lie flat on the bed or on a stool or sofa.

[0069] 4. When an elder person is in a posture of falling to the ground, for example, for those under 1.8 meters in height, whether they are lying flat on their back with their knees bent, struggling with their hands, or crawling on all fours, the height of their limbs will not exceed 0.8 meters.

[0070] As for occasional actions such as bending over, squatting, and even climbing, although dangerous, their body postures also correspond to different distribution relationships in vertical height.

[0071] 2. If the same coding method as the external presentation information coding is used, corresponding to the same preset height intervals, all the codes reflecting the various possible behaviors and postures of a human body in various places in the room can be preset in the system as target codes (sets). Then, for a certain presentation information coding from the outside at a certain time, a target code corresponding to the mirror image of the presentation information coding can be registered from the target code set in this system using the matching method. Through this target code, it is known that this presentation information coding reflects a certain possible behavior and posture of the human body at this place.

[0072] As can be seen from the above description, if several joint heights are reasonably selected to observe the distribution of postures of human behavior at different heights, the behavior posture that the person may currently be in can be judged from the distribution of human body presentation information at multiple heights in one place. In this way, if the same encoding method as described in step S102 is adopted, the human body presentation information at the same three heights is represented by P1, P2, and P3, and the binary representation of human body presentation information is 1, and no human body presentation information is 0, and the address position is also represented by A, B, C...N, etc., then the encoding arranged in the form of N+P1+P2+P3=NP1P2P3 can correspondingly reflect the possible posture of human behavior corresponding to the N address illustrated in step S102. Still using the three observation heights in step S102 as an example (for those under 1.8 meters in height), if the address represented by A is a bedroom, then code A110 reflects that the current posture of the human body may be climbing a ladder in the bedroom, or standing on a stool, sofa, or bed with both feet off the ground; if the code is A010, it reflects that the human body is sitting on a bed or stool with both feet off the ground; if the code is A011, it should be sitting on a bed, stool, sofa, or leaning over with both feet on the ground; if C represents a bathroom, then code C011 indicates that the human body may be sitting on the toilet, or leaning over; if the code is N001, it must reflect that the human body is lying on the ground at N place or squatting with its head down; if the code is N100, it indicates that someone is climbing a ladder at N place or falling from the sky; and code 101 cannot have a corresponding human behavior.

[0073] In this way, a human body presentation information distribution consisting of human body information displayed at multiple levels at an address can be formed, with numbers or characters representing each level to form a string as the target code to reflect the possible behavior posture of a person at this location. Of course, its accuracy is related to the selected level heights and number of levels.

[0074] 3. Since the target code and the presentation information code are both strings with the same arrangement format, a target code that is completely identical to a presentation information code and mirror-corresponds to the target code can be registered from the target code set by using a method such as data matching. Therefore, the duration of recording the matching state of the presentation information code and the target code in step S103 is equivalent to recording the duration of the matching target code (appearance), that is, recording the duration of a certain behavior represented by the target code.

[0075] In daily life, including abnormalities such as difficulty in movement, the duration of various human behavior postures in different occasions should have an allowable limit, so a value can be determined for the coded data represented by each target code, that is, the time limit, which is the time threshold corresponding to the target code. For example, in bedroom B, you should get up within 10 or 12 hours of lying down (sleeping) at night. If you have not shown the behavior of getting up or getting out of bed (standing, walking) during or after 10 or 12 hours, then an outsider needs to pay attention to observation. If three detection heights are also set in bedroom B, and the same coding method as in S102 is used, then in the presentation information coding obtained by detecting the human body presentation information at three heights of 1.3 meters, 0.6 meters and 0.2 meters, only the behavior posture corresponding to B010 may be sitting or lying on the bed and the couch with both feet off the ground, so the time threshold corresponding to the target code B010m (the code with the suffix letter m is the target code, the same below) can be set to 10 or 12 hours. Of course, if four detection heights of 1.3 meters, 0.9 meters, 0.6 meters and 0.2 meters are set, it is possible to further distinguish whether the person is sitting with both feet off the ground or lying flat. Among them, the target code B0110m corresponding to the posture of sitting on a bed or a couch sofa with both feet off the ground, its time threshold can be allowed to be, for example, 3 hours; and the target code B0010m corresponding to the posture of lying flat with both feet off the ground, its time threshold is still 10 or 12 hours. For another example, whenever the posture distribution information of an elderly person changes from standing (such as bathing), walking or sitting to appearing only at a height below 0.7 meters from the ground, if the duration exceeds 1 minute, it should be checked as soon as possible whether the person is in a posture of falling and lying on the ground, and the allowed duration corresponding to this human height distribution posture can be set within 1 minute. Then the time threshold assigned to the target code corresponding to this posture, such as C001, is 1 minute. Similarly, the time thresholds corresponding to the target codes A001, B001, N001, etc. in the set are all 1 minute

[0076] By using the time thresholds corresponding to these target codes as a reference and comparing them with the duration of the actual behavior of the current external human body in the same posture, it can be found out whether the current human body activity may be in an abnormal state because it exceeds the allowable duration.

[0077] The characteristic information codes obtained by the first preset height interval, the second preset height interval, and the third preset height interval are used as examples to explain the execution steps of S103 (refer to Figure 3 ):

[0078] If the code C011 is generated in step S102, in step S103, the target code C011m corresponding to the image of C011 will be matched from the target code set, and then the duration TC011 of C011 will be recorded. At the same time, TC011 will be compared with the time threshold TC011m assigned to the target code C011m. If the time threshold of the target code C011m is TC011m=30 minutes, the execution result of S103 is to see whether TC011 exceeds 30 minutes, that is, whether TC011 / TC011m>1 appears in the end. As long as TC011 / TC011m>1 appears, enter S104.

[0079] S104: If the duration is greater than a time threshold corresponding to the target code, a help message is generated.

[0080] In an optional implementation manner, if the time TC011 is greater than the time threshold TC011m corresponding to the target code C011m, that is, TC011 / TC011m>1, a help message is generated in S104 to call for help.

[0081] It can be seen that if the human body information obtained at each preset height is continuous real-time information, then as described in the above steps S101 to S103, the pre-established target code can be used as a reference to determine whether the human body behavior in the current room is abnormal. In an optional implementation, methods such as human body thermal imaging scanning technology or laser (radar) scanning imaging technology can be used to achieve effective application.

[0082] However, if a passive infrared probe composed of a pyroelectric sensor is used to obtain human body presentation information, only discontinuous human body presentation information can be obtained under current common technical conditions. This is because the current common commercial passive infrared probe can only detect human body activities that reach a certain amplitude or above. When human body activities change from obvious to static or inconspicuous, the human body presentation information obtained thereafter may be zero. In this way, even if the person being cared for does not leave the same (care area) address, but the behavior at the same body height changes from obvious activity to inconspicuous or stops, for example, stopping to stand while walking, closing eyes to rest after sitting down, lying down and falling asleep, etc., the human body presentation information will change from non-zero to all zero, that is, the presentation information code will change from N111 to N000 instead of continuously maintaining N111. A passive infrared detection system with such characteristics that the human body behavior posture does not change, but the obtained human body presentation information changes from non-zero to all zero, obviously cannot directly use the methods of the above steps S101 to S103 to obtain the correct conclusion.

[0083] In an optional implementation, the presentation information code consisting of non-all-zero human body presentation information can be used as the first presentation information code; and the presentation information code consisting of all zero human body presentation information can be used as the second presentation information code.

[0084] The process of recording the duration of the time when the presentation information code is in a matching state with the target code comprises the following steps: the target code comprises a first code and a second code; if the presentation information code changes from being in a matching state with the first code to being in a matching state with the second code, then continuing to record the duration of the time when the presentation information code is in a matching state with the second code; wherein the time threshold corresponding to the second code corresponds to the first code.

[0085] Among them, the time threshold corresponding to the second code matches the first code, that is, the selection of the second code is associated with the first code. After determining that the first code is changed to the second code, the time threshold corresponding to the second code can be determined through the first code. Taking the first code as A or B and the second code as C as an example, after the code matching the presentation information code changes from A to C, or from B to C, after matching, the time threshold corresponding to the duration of the recorded second code C is associated with the first code A or C, that is, the first code A and the first code C correspond to different time thresholds respectively.

[0086] In one embodiment, in step S101, human body presentation information is obtained from two preset height intervals, and the presentation information code is arranged in the same coding method as in S102, and then the information code consisting of non-all-zero information is used as the first code; and the information code of the human body presentation information that is all zero is used as the second code. When the presentation information code changes from the first code to the second code in S103, the time when the presentation information code continues to be the second code is continuously recorded, and the target code matching the first code is selected as the second code based on the previous first code. The target code preset in the system can also be used as a reference to determine whether a human behavior reflected by the presentation information code currently obtained by the passive infrared probe may be in a certain abnormal state.

[0087] The specific instructions are as follows:

[0088] Figure 2 FIG. 1 is a schematic diagram of an indoor nursing assistance method for a specific application example. Figure 2As shown, in step S101, for one address, only two preset heights of 1.3 meters and 0.8 meters are used to obtain human body presence information; the detection areas of the passive infrared probes D1 and D2 set at the two heights of 1.3 meters and 0.8 meters are made to be as small as possible in the vertical direction, for example, within 30°, and as wide as possible in the horizontal direction, for example, a relatively flat sector-shaped space of more than 100° (preferably, a curtain-type infrared probe is used), and the lower boundaries of the detection areas of the two probes in the vertical direction do not overlap each other in the horizontal direction of the entire front sector, as shown in FIG. Figure 2 As shown, it is ensured that the detection of the presentation information of human activities in the front fan area at different heights will not produce overlapping errors. Since the low-level human presentation information obtained at a height close to the ground is not used, the format of each presentation information encoding will be reduced by one bit, becoming N+P1+P2=NP1P2 as mentioned above. Of course, this means that it is not possible to directly judge whether the human activity behavior in the detection area has shown a posture of falling to the ground through the human activity information obtained from the two passive infrared probes arranged in this way.

[0089] In step S102, the same coding method is used to generate the presentation information code corresponding to the human body presentation information obtained at the two preset heights in S101 in combination with the address information; similarly, the mirror image corresponding codes of all presentation information codes are preliminarily formed into a target code set. However, for the presentation information code (second code) in which the human body presentation information is all zero, it is not because the human body leaves the current address that the presentation information disappears, but because the body limbs that can be detected from a height of 0.8 meters to 1.3 meters have stopped moving, or the body is completely below 0.8 meters and cannot be detected. Therefore, there must be a corresponding target code to reflect its possible behavior, but there is more than one target code. Of course, the time threshold of each target code is different. For example, after entering the bedroom W, the behavior of sitting down occurs. In S102, the presentation information code of W11 is first obtained, and then the presentation information code of W01 is obtained. If you close your eyes and rest after sitting down (almost motionless), you will get the presentation information code W00. The time threshold of the corresponding target code W00m can be allowed to be, for example, 2 hours. If the person falls down while walking in the bedroom and the code W00 appears, the time threshold of the corresponding target code W00m can only be allowed to be, for example, 1 minute. Therefore, each presentation information code (second code) NP1P2=N00 with all zeros in the human body presentation information will correspond to two target codes, represented by N00m1 and N00m2 respectively.

[0090] After entering S103, when the presentation information code changes from the first code to the second code, the duration of the second presentation information code will continue to be recorded, and the second code matching the current one will be selected based on the previous first code. Taking the above example, the presentation information code changes from the first code to the second code in the bedroom W, that is, from non-zero presentation information codes W11 and W01 to all-zero presentation information code W00, then when facing the same presentation information code W00, it is necessary to consider what behavior caused it, that is, it is necessary to refer to whether the presentation information code before W00 is W01 or W11, in order to decide whether the current corresponding target code should be W00m1 or W00m2.

[0091] The following examples illustrate the operation of S103 in the following scenarios:

[0092] After the elder enters the living room A and sits on the sofa, as long as he does not move motionlessly after sitting down so that the presentation information code A01 is detected at least once at a height of 0.8 meters within, for example, 2 minutes, even if he closes his eyes and rests so that his body is almost motionless and the presentation information code A00 appears in S103, because A00 appears after A01 from A11 to A01, S103 will use A01 before A00 as a basis, select the corresponding target code A00m1's time threshold and compare it with the duration of A00. If the time threshold of TA00m1 is 2 hours, when the result TA00 / TA00m1>1 appears, it will enter S104 to send a message, requiring external personnel to use audio / video equipment to check why the elder has not gotten up for 2 hours. If the elderly person gets up but feels dizzy and uncomfortable and sits down or even falls down during the period of TA00 / TA00m1<1 (i.e. within 2 hours), for example, he or she remains almost motionless for more than 2 minutes, then S103 will select the target code A00m2 according to A11 and compare the time threshold with the duration of A00 because the code A00 appears directly after the code A11. If TA00m2=2 minutes, when TA00 / TA00m2>1 appears, i.e. after 2 minutes, S103 will enter S104 to generate a help message and send out a call for help.

[0093] For another example, after the elder enters the bathroom C and sits on the toilet, S103 will continuously present the information codes C11, C01, C01... That is, after the elder sits on the toilet, there will be intermittent body movements at a detection height of 0.8 meters. Although the C00 code will appear after the C01 code due to the immobility, S103 selects the target code C00m1 that matches C00 based on the previous code C01. If the time threshold for allowing C00m1 is, for example, 99 seconds, as long as the elder does not remain still during the 99 seconds and TC00 / TC00m1>1 appears in S103, then S103 will not enter the subsequent S104, but will re-record the duration of the reappearing C00 code after the reappearance of the code C01 and compare it with TC00m1. However, if at any time the elderly person falls to the ground and struggles due to discomfort such as heart attack caused by constipation, and there is no human body presence information code C01 or information code C11 representing standing at a height of 0.8 meters within 99 seconds, S103 will enter S104 when TC00 / TC00m1>1 (that is, after 99 seconds) to generate a help message and send out a call for help.

[0094] Similarly, in bathroom C, if the elderly person accidentally slips while standing and bathing, causing the presentation information code C00 to appear in S103, because it comes directly from code C11 to code C00, S103 will select the time threshold of target code C00m2 as a reference based on code C11 being code C00 at this time. If the allowed time threshold TC00m2=1 minute, then S103 will enter S104 to generate a help message and send out a call for help after TC00 / TC00m2>1 (i.e. 1 minute).

[0095] From the above, it can be seen that after the preset height for detecting the human body presentation information is arranged only at two heights that are not near the ground, such as 1.3 meters and 0.8 meters, and the obtained target code is divided into the first code and the second code, when the presentation information code changes from the first code to the second code, the duration of the second code of the presentation information continues to be recorded, and the target code that matches the previous first code is selected as the second code. In this way, steps S101 to S104 can be used in the same way, and passive infrared detection technology can be used to take multi-faceted care of the behavior of the elderly when living alone, and timely send out help for suspected abnormal conditions in their physical activities, and contact external caregivers as soon as possible for verification and rescue.

[0096] In an optional embodiment, the passive infrared probe in the non-curtain-shaped detection range can also achieve a certain degree of detection after, for example, shielding part of the probe lens, or adding some structural restrictions, reducing the detection angle α of the probe, etc. Figure 2 Application shown.

[0097] Figure 3FIG. 1 is a schematic diagram of an indoor nursing assistance method for another specific application example. Figure 3 As shown, the above example is explained in combination with the address information. In the indoor care help method of embodiment 1, the presentation information code NP1P2P3 under the address N can be obtained in combination with the address information N, and the duration TNP1P2P3 of the presentation information code NP1P2P3 is recorded; then the target code NP1P2P3m corresponding to the mirror image of the presentation information code NP1P2P3 is matched from the target code set, and the duration TNP1P2P3 of the presentation information code NP1P2P3 is compared with the time threshold TNP1P2P3m corresponding to the target code NP1P2P3m, and if TNP1P2P3 / TNP1P2P3m is greater than 1, a help message is generated.

[0098] The help information can be an image, text, voice and various coded files, such as a frame image, a help phone, a help text message or a help email, etc. Sending the help information outward means sending the help information to external information receiving devices such as the family of the care recipient, the on-duty caregiver or the community service agency.

[0099] Optionally, the help information corresponds to the target code. That is, if the duration of a certain behavior posture exceeds the time threshold of its corresponding target code, it means that the current human behavior may be in an abnormal state. If the help information is a help email, the content of the help email includes the abnormal behavior of the person being cared for. The sent help information allows external personnel to use video / audio equipment to observe and confirm the abnormal behavior in a timely manner, thereby improving the efficiency of rescue.

[0100] The indoor nursing help-seeking method provided in the first embodiment obtains the human body presentation information in each preset height interval, obtains the presentation information code, records the duration of the presentation information code and the target code in a matching state, and compares it with the time threshold corresponding to the target code, and generates a help-seeking message when the time is greater than the time threshold. Based on this, if the daily behavior posture of the human body is converted into a target code that can be represented by a one-to-one corresponding target code, and the target code is assigned a time value (a reasonable time threshold is set), the allowable duration (threshold) of various behavior postures representing the human body in daily activities can be used as a reference to compare with the duration of the indoor individual's activity behavior. When an abnormal behavior state with a duration greater than the time threshold occurs, a help-seeking message is sent to the outside, informing the outside personnel to conduct timely verification and confirmation (through video and audio equipment) to decide whether rescue is needed, thereby realizing the efficient use of unattended indoor and full-day rescue outside.

[0101] Figure 4 FIG. 1 is a module structure diagram of the indoor nursing assistance device of the second embodiment. Figure 4FIG. 1 is a module structure diagram of an indoor nursing assistance device according to Embodiment 2, including:

[0102] The feature information acquisition module 201 is used to acquire the human body presentation information within each preset height interval; the presentation information encoding module 202 is used to obtain the presentation information code according to the human body presentation information within each preset height interval; the time recording module 203 is used to record the duration of the presentation information code and the target code in a matching state; the help information sending module 204 is used to generate a help information when the duration is greater than the time threshold corresponding to the target code.

[0103] The indoor nursing help-seeking device provided in the second embodiment obtains the human body presentation information in each preset height interval, obtains the presentation information code, records the duration of the presentation information code and the target code in a matching state, and compares it with the time threshold corresponding to the target code. When the duration is greater than the time threshold, a help-seeking message is generated. Based on this, if the daily behavior posture of the human body is converted into a target code that can be represented by a one-to-one corresponding target code, and the target code is assigned a time value (a reasonable time threshold is set), the allowable duration (threshold) of various behavior postures representing the human body in daily activities can be used to compare with the duration of the indoor individual's activity behavior. When an abnormal behavior posture greater than the time threshold appears, a help-seeking message is sent out to inform external personnel to conduct timely verification and confirmation (through video and audio equipment) to decide whether rescue is needed. Thereby realizing the efficient use of unattended indoor and full-day rescue outside.

[0104] An embodiment of the present invention provides a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the steps of any one of the embodiments of the indoor nursing assistance request method are implemented.

[0105] The computer device provided in this embodiment obtains the human body presentation information within each preset height interval, obtains the presentation information code, records the duration of the presentation information code and the target code in a matching state, and compares it with the time threshold corresponding to the target code, and generates a help message when the duration is greater than the time threshold. Based on this, if the daily behavior posture of the human body is converted into a target code that can be represented by a one-to-one corresponding target code, and the target code is assigned a time value (a reasonable time threshold is set), the normal duration (threshold) allowed by various behavior postures of the human body in daily activities can be used to compare with the activity behavior duration of the individual indoors, and when an abnormal state greater than the time threshold occurs, a help message is sent out to allow external personnel to know the help message, thereby realizing the efficient use of unattended indoor and full-day external care and rescue. The embodiment of the present invention provides a computer-readable storage medium, on which a computer program is stored, and when the computer program is executed by a processor, the steps of any embodiment of the indoor care help method are implemented. In addition, the program usually stored in a storage medium is executed by directly reading the program out of the storage medium or by installing or copying the program to a storage device (such as a hard disk and or memory) of a data processing device. Therefore, such a storage medium also constitutes the present invention. The storage medium can use any type of recording method, such as paper storage media (such as paper tape, etc.), magnetic storage media (such as floppy disks, hard disks, flash memory, etc.), optical storage media (such as CD-ROM, etc.), magneto-optical storage media (such as MO, etc.), etc.

[0106] The computer-readable storage medium provided by the embodiment of the present invention obtains the presentation information code by acquiring the human body presentation information within each preset height interval, records the duration of the presentation information code and the target code in a matching state, and compares it with the time threshold corresponding to the target code, and generates a help message when the duration is greater than the time threshold. Based on this, if the daily behavior posture of the human body is converted into a target code that can be represented by a one-to-one corresponding target code, and the target code is assigned a time value (a reasonable time threshold is set) to form a reference database, the normal duration (threshold) of various behavior postures representing the human body in daily activities can be used to compare with the duration of the activity behavior of the individual indoors, and when an abnormal state greater than the time threshold occurs, a help message is sent to the outside to inform the outside personnel to conduct timely verification and confirmation (through video and audio equipment) to decide whether rescue is needed. Thereby, the efficient use of rescue is achieved with no one in the room and someone outside to take care of it all day.

[0107] Figure 5 Schematic diagram of the detection pile structure of the third embodiment. Figure 5As shown, it includes a detection pile bracket 301 and one or more detection units 302 arranged on the detection pile bracket; each detection unit 302 is configured to detect human body presentation information in corresponding preset height intervals.

[0108] Optionally, the detection unit 302 is a curtain probe, which includes a focusing window composed of an annular focusing bracket and a Fresnel lens fixed along the bracket ring surface; a sensor for detecting human infrared body feature information is arranged at the focus of the annular focusing bracket.

[0109] Figure 6 The following is the structural principle diagram of the curtain probe. Figure 6 As shown, the focusing window is formed by the annular focusing bracket 402 and the Fresnel lens 403 , and the infrared pyroelectric sensor (PIR) 401 is fixed at the focus of the focusing bracket 402 .

[0110] Specifically, Figure 6 As shown, the curtain probe used in this embodiment can be a curtain probe made of a "single / double-zone multi-segment horizontal" Fresnel lens - its sensor 401 is fixed at the focus of the annular focusing bracket 402, and the annular focusing bracket 402 and the lens 403 form a circular arch outward focusing window. If the sensor 401 uses a wide-angle human infrared pyroelectric sensor PIR, the curtain probe can detect the horizontal front angle , the detection angle perpendicular to the front , so that the curtain probe can obtain a relatively flat fan-shaped detection capability in front. If the focusing window of such a curtain probe is placed horizontally facing the room, and several probes are fixed at a certain distance in the vertical direction and maintained at an elevation or depression angle of about β / 2, these probes can jointly detect the body activities of the same person at the same location at different heights within the detection range without signal overlap, thereby obtaining the corresponding human body presentation information in each preset height interval.

[0111] If such detection piles can be set up on the vertical surface with a relatively open field of view indoors, each detection pile can perform layered detection at different heights on the human body presentation information in the indoor range of about 100° in the horizontal fan shape in front.

[0112] Optionally, Figure 7 is a schematic diagram of the detection unit structure of an optional implementation mode, such as Figure 7 As shown, the detection unit 302 includes a non-curtain probe 401 and an external shielding structure 501; the shielding structure 501 is arranged outside the probe 401 to limit the vertical opening angle of the probe 401 to the front.

[0113] Specifically, Figure 7As shown, by partially shielding the optical path, the shielding structure 501 is used to limit the vertical angle of the probe 401 to the front, so that the probe has a relatively flat detection capability. If the shielding structure is placed horizontally in the room, and a number of probes are fixed at a certain distance in the vertical direction, these probes can jointly detect the body activities of the same person at the same location at different heights within the detection range, and detect the human body presentation information in the corresponding preset height intervals.

[0114] Optionally, Figure 8 This is a schematic diagram of the split detection pile support structure. Figure 8 As shown, the detection pile bracket includes a plurality of split detection pile brackets 601; a detection unit 302 is fixed on the side wall of each split detection pile bracket 601; and each detection unit 302 is electrically connected through a cable. One side of each split detection pile bracket 601 can be used to set a detection unit 302, and the other side is used to be fixed to a vertical surface; the bottom of the split detection pile bracket 601 can be used to be fixed to a horizontal surface.

[0115] The split detection pile 601 provided in this optional implementation manner facilitates flexible and efficient deployment of the detection units when a building structure or furniture blocks the detection range of the detection unit 302 .

[0116] The detection pile provided in the third embodiment facilitates the installation personnel to deploy the detection unit 302 for detecting the human body presentation information of the cared person, thereby improving the efficiency and convenience of installing the detection unit 302 .

[0117] Fig. 9 Schematic diagram of the detection pile structure of the fourth embodiment. Fig. 9 As shown, the detection pile also includes a first processing unit 701 and a first communication unit 702;

[0118] The first processing unit 701 is arranged on the detection pile bracket 301 and is respectively connected to the detection unit 302 on the detection pile bracket 301; the first processing unit 701 is connected to the first communication unit 702; the first communication unit 702 is arranged on the detection pile bracket; the first processing unit 701 is configured to obtain the presentation information code according to the human body presentation information in each preset height interval, and transmit the presentation information code to the outside through the first communication unit 702.

[0119] In an optional embodiment, the first processing unit 701 is configured to obtain a presentation information code based on human body presentation information within each preset height interval; and is configured to record the duration of the presentation information code and the target code in a matching state when the presentation information code and the target code are in a matching state; and is also configured to generate a help message when the duration is greater than a time threshold corresponding to the target code, and send the help message to the outside through the first communication unit 702; wherein the time threshold corresponds to the target code.

[0120] In an alternative embodiment, if Fig. 9 As shown, the detection pile of the fourth embodiment further includes a working environment monitoring unit 703 .

[0121] The working environment monitoring unit 703 is connected to the first processing unit 701, and is used to monitor the self-operation guarantee of the system and the environmental status of the guarded area, and promptly send abnormal condition information of the working environment to the first processing unit 701. While the first processing unit 701 generates prompt information, it also sends the abnormal environmental condition information to the outside through the first information unit 702.

[0122] Among them, the working environment monitoring unit is a power supply monitoring device, a temperature detection device, an external obstacle detection device, a gas detection device and a smoke and fire detection device.

[0123] The detection pile provided in Example 4 integrates the detection unit 302, the first processing unit 701 and the first communication unit 702, and the working environment monitoring unit 703, has complete independent operation capabilities, and is convenient for multi-point deployment. By timely transmitting the presentation information code obtained by combining the human body presentation information detected by the detection unit 302 with the address information to the external host for centralized processing (the host records the duration of each presentation information code and the target code in a matching state, and then compares it with the time threshold corresponding to the target code), it is possible to timely detect whether the behavior state of one person in the room is abnormal. If the abnormal behavior is reported to external personnel in a timely manner for verification and confirmation, the elderly who have indeed encountered an unexpected situation can be rescued in time, thereby maximizing the efficiency of system operation.

[0124] Fig.10 The module structure diagram of the indoor nursing assistance system of the fifth embodiment is shown in FIG. Fig.10As shown, it includes a second processing unit 801, a second communication unit 802 and a detection post 803; the second processing unit 801 is connected to the second communication unit 802, and is used to connect to the detection units 302 respectively; each detection unit 302 is configured to detect the human body presentation information of the corresponding preset height intervals; the second processing unit 801 is configured to obtain the presentation information code according to the human body presentation information in each preset height interval; and is configured to record the duration of the presentation information code and the target code in a matching state when the presentation information code and the target code are in a matching state; and is also configured to generate a help message when the time is greater than the time threshold corresponding to the target code, and send the help message outward through the second communication unit 802; wherein the time threshold corresponds to the target code.

[0125] In an alternative embodiment, if Fig.10 The second communication unit 802 is also configured to collect the presentation information code transmitted by the first communication unit 702; and is configured to record the duration of the presentation information code and the target code in a matching state when the presentation information code and the target code are in a matching state; and is also configured to generate a help message when the duration is greater than a time threshold corresponding to the target code, and send the help message outward through the second communication unit 802; wherein the duration threshold corresponds to the target code.

[0126] In an alternative embodiment, if Fig.10 As shown, the indoor nursing help system of Example 5 also includes a router unit 803, and the router unit 803 is connected to the second processing unit 801. When the second processing unit 801 is used to generate help information, it controls the router unit 803 to achieve interconnection communication with the external network within a certain time, so that the second communication unit 802 and the indoor audio / video monitoring equipment connected to the router unit 803 can send the help information and the audio / video information of the indoor scene to the external network through the router unit 803 within this allowed time; and outside these allowed times, the router unit 803 will not perform interconnection communication with the external network.

[0127] The router unit 803 is connected to the external network, so that outsiders can obtain help information through the external network and use audio / video equipment to check the status of the nursing site to decide whether to provide assistance.

[0128] The second processing unit 801 may be a general-purpose processor, such as a DSP processor, etc. The second communication unit 802 may include a 4G communication module, a WiFi communication module, or a satellite communication module, etc. Preferably, the second communication unit 802 is also used to connect to a server and send the help information to the server, so that relevant personnel can obtain the help information through the server.

[0129] In the indoor nursing help-seeking system provided in the fifth embodiment, the detection unit 302 obtains the human body presentation information within each preset height interval, and the second processing unit 801 obtains the presentation information code according to the human body presentation information, records the duration of the presentation information code and the target code in the matching state and compares it with the time threshold corresponding to the target code, and generates help-seeking information when the duration is greater than the time threshold. And the help-seeking information is sent out through the second communication unit 802. Based on this, if the daily behavior posture of the human body is converted into a target code that can be represented by a one-to-one corresponding target code, and the target code is assigned a time value (a reasonable time threshold is set), the duration (threshold) of the target code reflecting the various behavior postures of the human body during indoor activities can be used to compare with the duration of the indoor individual's activity behavior, and when an abnormal posture greater than the time threshold appears, the help-seeking information is sent out, and the external personnel are informed to conduct timely verification and confirmation (through video and audio equipment) to decide whether rescue is needed. Thereby realizing the efficient use of unattended indoor and full-day rescue outside.

[0131] The working environment monitoring unit 901 is connected to the second processing unit 801, and is used to monitor the self-operation guarantee of the system and the environmental status of the guarded area, and transmit the environmental status abnormality information of the working environment status to the second processing unit 801, so that the second processing unit generates prompt information and sends the environmental status abnormality information to the outside through the second communication unit. The working environment status monitoring unit 901 is connected to the second processing unit 801, and is used to send the environmental status abnormality information of the guarded area to the second processing unit 801 when the environment of the guarded area is in an abnormal state; the second processing unit 801 is also used to send the environmental status abnormality information through the second communication unit 802.

[0132] The indoor care assistance system provided in the sixth embodiment can timely detect whether the operating environment inside and outside the system is abnormal through the coordinated application of the working environment information monitoring unit 901. When the environmental conditions are abnormal or even dangerous, it can timely report to the external caregivers for verification or rescue, fully ensuring the effective operation of the system. Of course, it can also remind indoor personnel (when high temperature, gas overflow and fireworks occur) to avoid danger or escape as soon as possible.

[0133] Fig.12 The module structure diagram of the indoor nursing assistance system of the sixth embodiment is shown in FIG. Fig.12As shown, the indoor nursing assistance system further includes an alarm module 1001; the alarm module 1001 is connected to the second communication unit 902 and is configured to generate an alarm signal according to the assistance information.

[0134] Among them, the alarm signal includes indoor alarm signal and outdoor alarm signal, such as warning sound and light signal, audio prompt, etc. The indoor alarm signal is used to remind the indoor person being cared for. If there is an error in the help information, it is convenient for the person being cared for to eliminate the help request in time. The outdoor alarm signal is used to remind the outdoor person being cared for, such as a broadcast signal set in a public place in the community, to remind relevant personnel to provide assistance.

[0135] The indoor nursing assistance system of any of the above embodiments is explained below through a specific application example.

[0136] Among them, the host 1101 is a single-chip host, and the encoding receiving module 1103, the router unit 1104, the timing module 1105, the voice / audio module 1106 and the environmental information detection module 1107 can all be peripheral circuits. The host power supply 1102 can be an AC / DC power supply or a battery power supply. The encoding receiving module 1103 is connected to the detection unit 302 and can be a wireless communication module or a wired communication module. The timing module 1105 is used to record the duration of the presentation information code and the target code in a matching state, and can be a pulse timing circuit. The voice / audio module 1106 is used to broadcast alarm and prompt information, and can be an external power amplifier.

The host 1101 can control the voice / audio module 1106 to play voice according to the report information to prompt the user to remove / clear the obstacle in time.
