Description

Technical Field

[0001] The present invention relates to a method and system for emergency assistance response for the elderly in a smart home environment, and belongs to the technical field of smart home. Background Art

[0002] Sensors in smart homes are the key to obtaining information. For example, motion sensors can detect the movement of the human body. Based on infrared or microwave technology, when a human body enters the sensing area of the sensor, it will cause the reflection of infrared rays or the change of microwaves, thereby triggering the sensor to send a signal. In the application of elderly assistance, motion sensors can be installed in areas such as bedrooms and living rooms to monitor the daily activities of the elderly. Vital sign sensors are another important type. For example, wearable heart rate sensors and blood pressure sensors. Heart rate sensors generally use optoelectronic sensor technology to measure the heart rate by detecting the change in the absorption of light by blood. Blood pressure sensors have various types, including sensors based on the oscillometric method, which measure blood pressure by detecting the oscillatory change in the pressure inside the cuff. These sensors can monitor the vital signs of the elderly in real time. Once an abnormal situation occurs, such as a too fast heart rate or too high or too low blood pressure, an alarm can be sent in time. The smart home system mainly relies on communication technologies such as Wi-Fi, ZigBee, and Bluetooth. Wi-Fi technology provides a high-speed and stable network connection, enabling smart home devices to communicate with the home network and external servers. For example, when an emergency occurs, a family with a smart home system can send the health data and location information of the elderly to a medical institution or the mobile phone of the children through Wi-Fi.

[0003] Currently, the most commonly used technology is that when the elderly call 120 due to illness, they manually send their physical condition to medical staff. This process is inefficient. Secondly, when locating the position of the elderly through the elderly's mobile device, only the azimuth of the elderly in the horizontal direction can be located. If the elderly do not tell the floor where they are when calling 120, the floor where the elderly are located cannot be known. Generally, the family members of the elderly assist the medical staff to find the floor where the elderly are located. This process is inefficient. Finally, the existing technology only considers that one ambulance carries only one patient corresponding to a call to 120. For other patients encountered during the driving of the ambulance, often a new ambulance needs to be dispatched to pick up the person. If an ambulance passing by can rescue other patients at this time, but no order to rescue is issued to this ambulance, the efficiency of dispatching another ambulance may be much lower than the rescue efficiency of this passing ambulance.

[0004] Therefore, the efficiency of emergency assistance response for the elderly is insufficient. Summary of the Invention

[0085] Embodiment 1:

[0086] Refer to Figure 1 As shown, it is a schematic flowchart of a method for elderly emergency assistance response in a smart home environment provided by an embodiment of the present invention. In this embodiment, the method for elderly emergency assistance response in the smart home environment includes:

[0087] S1.

Among them, the emergency response system includes an emergency response center, a first aid station, an ambulance, and a medical station.

[0088] In the embodiment of the present invention, the help request refers to the telephone information of the elderly dialing 120 and a text message containing the account and password of the mobile device automatically sent to the 120 party by the mobile phone end when it monitors that the 120 call has been made after the elderly dials the 120 call. The linked home device refers to a home device that is bound to the remote control system after the control right of the software of the smart home is handed over to the remote control system in the elderly's mobile phone with the consent of the elderly when installing the smart home in the elderly's home. The emergency response center refers to a data reception and data processing center for answering help calls and issuing first aid arrangements based on the help calls. The first aid station is a station that dispatches ambulances without carrying other patients. The ambulance is a vehicle for transporting patients from home to the medical station. The medical station refers to a hospital that treats the diseases of patients. The aforementioned first aid station and ambulance have temporary first aid equipment and can only play a role in rescue. Actually, the medical station is still needed to treat the diseases of patients.

[0089] Furthermore, in the embodiment of the present invention, by using the help request to determine whether there are any linked home devices for the elderly, it is used to automatically schedule the data monitored by the smart home of the elderly through the remote control system, reducing the problem of insufficient efficiency of manual upload.

[0093] S2. When there are linked home devices, the smart home devices are divided into medical devices and non-medical devices. The physical condition of the elderly is identified through the medical devices, and the location information of the elderly is identified through the elderly's help device based on the non-medical devices.

[0094] In the embodiment of the present invention, the medical device refers to a device for performing physical health monitoring, such as an electrocardiogram monitoring device, and the non-medical device refers to a device that is not specifically used for physical health monitoring, such as a monitoring device and a non-monitoring device.

[0095] In one embodiment of the present invention, the identifying the physical condition of the elderly person through the medical device includes: obtaining monitoring data of the medical device within a continuous period of time; identifying whether there are data anomalies in the monitoring data through a preset long short-term memory neural network to obtain abnormal monitoring results; querying the help text in the elderly person's help request; identifying the symptoms of the disease in the help text; and using the abnormal monitoring results and the symptoms of the disease as the physical condition.

[0096] Among them, the monitoring data corresponds to different data in different medical devices, such as the ECG monitoring data of the ECG monitoring device, the blood pressure monitoring data of the blood pressure monitoring device, etc. The abnormal monitoring result refers to whether the data is abnormal after the time series data is identified through the long short-term memory neural network, which includes two situations, one is that the data is normal, and the other is that the data is abnormal. The help text refers to the information about the elderly's own body described on the phone, and the symptoms of the disease refer to the text keywords in the help text, such as headache.

[0097] Further, in the embodiments of the present invention, based on the non-medical device, the positioning information of the elderly is identified through the help device of the elderly, so as to identify the floor where the patient is located without manual assistance.

[0098] In one embodiment of the present invention, the identifying the positioning information of the elderly through the help device of the elderly based on the non-medical device includes: positioning the horizontal position of the elderly through the help device; determining whether the non-medical device is a monitoring device; when the non-medical device is a monitoring device, determining whether there is an outdoor video in the monitoring video of the non-medical device; when there is an outdoor video in the monitoring video of the non-medical device, determining the first vertical floor of the elderly by using the following method:

[0099]

[0100] Wherein, H 1 represents the first vertical floor, h 0 represents the preset height of each floor, h 1 represents the height of the non-medical device indoors, θ 0 represents 180 degrees, θ 1 represents the shooting angle of the non-medical device indoors, I represents the monitoring video, H (I,max) represents the highest floor in the monitoring video, represents the lowest floor b after removing the floor a with the smallest area in the monitoring video, a H represents the middle floor in the monitoring video, H (I,mid) represents the lowest floor in the monitoring video, (I,min) represents the highest floor b' after removing the floor a' with the smallest area in the monitoring video, in the monitoring video; a′ Taking the horizontal position and the first vertical floor as the positioning information of the elderly; when the non-medical device is not a monitoring device and there is no outdoor video in the monitoring video of the non-medical device, retrieving the community video corresponding to the horizontal position, and collecting the opening time of the non-medical device; calculating the second vertical floor of the elderly according to the community video and the opening time by using the following formula:

[0101]

[0102]

[0103]

[0103] Wherein, H 2 represents the second vertical floor, v represents the average climbing speed of the elderly, the unit of v is height per second, t 2 represents the opening time, t 1Indicates the moment when the elderly person arrives at the first floor as shown in the community video;

[0104] Take the horizontal position and the second vertical floor as the positioning information of the elderly person.

[0105] Among them, the horizontal position refers to the location of the elderly person determined by a positioning system, such as GPS positioning technology. The video outside the window refers to a video that can see information about other buildings outside the window. It should be noted that when monitoring devices such as cameras are installed on the wall, there will be an angle θ between the section of the wall from the ground to the monitoring device (abbreviate this section of the wall as the lower side wall) and the shooting direction of the camera. 1 , when determining θ 1 , only consider the angle between the shooting direction of the camera and the lower side wall, that is, do not consider the angles such as the angle between the shooting direction of the camera and the left (right) side, the angle between the shooting direction of the camera and the upper side wall, etc. The opening moment refers to the starting moment when the elderly person turns on the smart home after entering the house.

[0106] Exemplarily, represents b in the monitoring video after removing the floor a with the smallest area a among the lowest floors,

[0107] represents that the height where the camera is located is below the middle of the height of this floor and the shooting angle is greater than 90 degrees, that is, the shooting direction is upward. Then the heights of other buildings corresponding to the video outside the window include A with only a small part missing, the middle floor B, and C. Among them, B is at the same height as the current floor, and A with only a small part missing is the floor one level below B that may be captured when the camera direction is upward, and C is the floor one level above B. represents b′ in the monitoring video after removing the floor a′ with the smallest area a′ among the highest floors, the principle is similar to the above represents b in the monitoring video after removing the floor a with the smallest area a among the lowest floors, and will not be elaborated further here.

[0108] S3. Query the emergency location of the first aid station, the vehicle location of the ambulance, and the medical location of the medical station respectively. According to the emergency location, the vehicle location, and the medical location, allocate a target first aid station, a target ambulance, and a target medical station for the positioning information.

[0109] In the embodiment of the present invention, the first aid location refers to the location where the first aid station is located, that is, the starting location of the ambulance dispatched by the first aid station without other patients and only medical staff. Here, the first aid station is used as the starting location of the ambulance without other patients, and the vehicle location of the ambulance is used as the starting location of the ambulance that may carry other patients. That is to say, after receiving the rescue request of the current elderly person, the emergency response center may dispatch a passing vehicle that already carries other patients to rescue the current elderly person.

[0110] In an embodiment of the present invention, allocating a target first aid station, a target ambulance, and a target medical station for the positioning information according to the first aid location, the vehicle location, and the medical location includes: obtaining the physical condition of the elderly person; analyzing the disease category of the elderly person by using the physical condition; querying the medical waiting time of the disease category; selecting the shortest waiting time from the medical waiting times; and selecting the initial first aid station, the initial ambulance, and the initial medical station of the positioning information from the first aid location, the vehicle location, and the medical location by using the following formula:

[0111]

[0112] {min(D xyv ,D uyv ) k}→x′,u′,v′

[0113] where x′ represents the initial first aid station, u′ represents the initial ambulance, v′ represents the initial medical station, d x～y represents the distance between any first aid location x and the positioning information y, d y～v represents the distance between the positioning information y and any medical location v, d u～y represents the distance between any vehicle location u and the positioning information y, R ij represents the reference speed of the ij section experienced by x~y, y~v, C ij represents the average speed of the ij section experienced by x~y, y~v in the next time period, D xyv represents the distance cost experienced by x~y, y~v, R i′j′ represents the reference speed of the i′j′ section experienced by u~y, y~v, C i′j′ represents the average speed of the i′j′ section experienced by u~y, y~v, D uyv represents the distance cost experienced by u~y, y~v, min(D xyy ,D uyv ) k represents D xyv and D uyv the smallest k Ds among them;

[0114] Determine whether there is a target first aid duration less than the shortest waiting duration among the first aid durations corresponding to the initial first aid station, the initial ambulance, and the initial medical station; when there is a target first aid duration less than the shortest waiting duration, use the initial first aid station, the initial ambulance, and the initial medical station corresponding to the target first aid duration as the target first aid station, the target ambulance, and the target medical station respectively; when there is no target first aid duration less than the shortest waiting duration, use the initial first aid station, the initial ambulance, and the initial medical station as the target first aid station, the target ambulance, and the target medical station respectively.

[0115] Among them, the medical waiting duration refers to the time that can be used for rescue for each disease category queried after analyzing the possible disease categories of the elderly. For example, for a serious disease, the elderly need to be rescued in time within 30 minutes after the elderly experience serious discomfort. If it exceeds this 30 minutes, the probability of successful rescue is extremely low. Then 30 minutes is the medical waiting duration. It should be noted that there are multiple disease categories, so there are also multiple corresponding medical waiting durations. The average speed refers to the average value of the actual driving speed of the vehicle estimated during this period. The smallest k Ds refer to k numerically small Ds selected in ascending order. It should be noted that from the foregoing definitions, the first aid station represents an ambulance without a patient, and the ambulance represents an ambulance that may carry a patient. Then when selecting the target first aid station, the target ambulance, and the target medical station, it is divided into the combination of the target first aid station and the target medical station, and the combination of the target ambulance and the target medical station, rather than the combination of these three, namely the target first aid station, the target ambulance, and the target medical station. For example, when there is no target first aid duration less than the shortest waiting duration, if the k Ds selected are all D xyv , that is, k Ds xyv , because these k Ds xyv are all calculated based on the first aid location and the medical location, they are k combinations. Assuming k is 3, it means there are three combinations. The 1st combination is the combination of the 1st target first aid station and the 1st target medical station, the 2nd combination is the combination of the 2nd target first aid station and the 2nd target medical station, and the 3rd combination is the combination of the 3rd target first aid station and the 3rd target medical station. During this process, there is no target ambulance, so "none" is used as the target ambulance. Therefore, the above-mentioned target first aid station, target ambulance, and target medical station are not a relationship that can be determined and obtained simultaneously, but a relationship that includes all possible combinations.

[0116] In another embodiment of the present invention, the analyzing the disease category of the elderly by using the physical condition includes: calculating the posterior probability corresponding to the physical condition by using the following formula:

[0117]
