Description

Technical Field

[0001] The present invention belongs to the technical field of positioning supervision, and in particular relates to a user positioning supervision method and system capable of defining a user-defined jurisdiction. Background Art

[0002] Dementia is a progressive degeneration of cognitive function caused by brain damage or disease. In severe cases, patients will be unable to distinguish between people, things, time, place and objects. When the patient's condition is serious, he or she needs to be sent to a rehabilitation institution for monitoring and treatment.

[0003] Rehabilitation institutions implement targeted supervision on people with dementia, the main purpose of which is to ensure their personal safety and social security. Medical staff conduct a comprehensive assessment based on the physical condition and cognitive performance of the supervised persons, and implement three levels of management based on the assessment results, namely strict management, general management, and loose management.

[0004] Most of the personnel positioning systems currently on the market can only display the movement trajectory of personnel based on their mobile phones, requiring medical personnel to manually check and determine whether they have left the supervision area. This undoubtedly increases the workload of medical personnel and is prone to inadequate supervision. Summary of the invention

[0005] Based on this, an embodiment of the present invention provides a user positioning supervision method and system with customizable jurisdictions, which aims to customize jurisdictions according to the management categories of dementia populations and automatically determine whether people have left the jurisdictions, so as to strengthen supervision while reducing the workload of medical staff.

[0021] If it is determined that both the first number and the second number are odd numbers, it is determined that the user has not left the corresponding supervision area;

[0022] If it is determined that the first number and the second number are not both odd numbers, it is determined that the user leaves the corresponding supervision area.

[0023] Furthermore, when the user's management level is the first level, the step of using the prohibition of crossing the boundary method to conduct the evaluation includes:

[0024] Determine the foot point of the perpendicular line from the user position to the corresponding regulatory area boundaries, and calculate the straight-line distance between each foot point and the user position;

[0025] The shortest distance between each perpendicular foot point and the user's position is determined as the user's escape distance;

[0026] Determine whether the user's disengagement distance is 0;

[0027] If the user's disengagement distance is determined to be 0, the user's disengagement degree is determined to be no disengagement;

[0028] If it is determined that the user's disengagement distance is not 0, it is determined that the user's disengagement degree is severe disengagement.

[0029] Furthermore, when the user's management level is the second level, the step of using the boundary distance measurement method to perform evaluation includes:

[0031] The shortest distance between each perpendicular foot point and the user's position is determined as the user's escape distance;

[0032] Determine whether the user's escape distance is less than or equal to a preset distance;

[0033] If it is determined that the user's disengagement distance is less than or equal to the preset distance, the user's disengagement degree is determined to be moderate to light disengagement;

[0034] If it is determined that the user's disengagement distance is greater than the preset distance, the user's disengagement degree is determined to be severe disengagement.

[0035] Furthermore, when the user's management level is the third level, in the step of using the circle center radius measurement method for evaluation, the user's degree of separation is evaluated based on the user's situation in the supervision area and the outdoor activity safety area.

[0063] Embodiment 1

[0064] According to an embodiment of the present invention, a method for user location supervision in a customizable jurisdiction is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from that shown here.

[0065] In this embodiment 1, a user location monitoring method with a customizable jurisdiction is provided, which can be used in electronic devices, such as computers. Figure 1 , Figure 1 A flowchart of an implementation of a user location supervision method for a customizable jurisdiction provided in the first embodiment of the present invention is shown, which specifically includes steps S01 to S04.

[0066] Step S01, setting various supervision areas and obtaining the user's location through a positioning device worn by the user.

[0067] Specifically, the corresponding supervision area can be set according to the supervision level. In this embodiment, firstly, an existing electronic map is imported. The map should have the function of picking up the longitude and latitude coordinates of any point. The longitude and latitude coordinates are in the WGS84 coordinate system format. In a clockwise direction, the required supervision area on the electronic map, for example, along the building boundary of the rehabilitation institution, is marked with point A. i , pick up the latitude and longitude coordinates of the point (x i ,y i ), where x i is the latitude of the point, y iFor example, if the longitude and latitude of the marking point are 117.966460 north latitude and 28.431002 Tokyo, then its longitude and latitude coordinates are (117.966460, 28.431002), where the longitude and latitude retain six decimal places and the actual deviation value can be within 0.1m. Then convert the marking point A. i The longitude and latitude coordinates are plane straight line coordinates (X i , Y i ), the calculation formula is: X i =R×cos(x i )×cos(y i ), Y i =R×cos(x i )×sin(y i ), where R is the radius of the earth, R = 6371.393 km, the calculation result is in km, and the accuracy is to three decimal places.

[0068] Furthermore, set a virtual marker point A i+1 , so that A i+1 Coincident with the starting point A1, that is, A i+1 Coordinate (X i+1 , Y i+1 )=A1 coordinates (X1, Y1), and finally starting from the starting point A1, connect the marked points A i With A i+1 , forming a closed polygon, the area inside the polygon is the regulatory jurisdiction, and the lines between the marked points are the boundaries of the regulatory jurisdiction.

[0069] In addition, the supervised person wears a device that supports GPS positioning and LBS positioning technology, such as a smart bracelet, and moves freely indoors and outdoors. Set the supervision time T j , the device feedbacks the location information of the supervised person at a certain moment and places a mark point A on the electronic map j , record the coordinates of the point (x j ,y j ), where x j is the latitude of the point, y j is the longitude of the point. Similarly, convert the marked point A j The longitude and latitude coordinates are plane straight line coordinates (X j , Y j ).

[0070] Step S02, determining the user's management level according to the user's IQ assessment results and ADL self-care ability assessment results.

[0071] It can be understood that the IQ assessment results and the ADL (Activities of Daily Living) self-care ability assessment results can be obtained through expert evaluation. In this embodiment, the management level F of the supervised person is set according to the IQ score results and ADL self-care ability score results of the supervised person using the following table, F∈{"strict management", "ordinary management", "loose management"}.

[0072]

[0073] It should be noted that the user's management level is divided into at least three levels, including the first level, the second level and the third level with gradually relaxed management requirements. It can be understood that the first level corresponds to strict management, the second level corresponds to ordinary management, and the third level corresponds to relaxed management. Among them, according to the user's management level, the corresponding supervision area is obtained, and according to the positional relationship between the user's position and the corresponding supervision area, it is judged whether the user leaves the corresponding supervision area. When the user's management level is the first level, the prohibited crossing boundary method is used for evaluation; when the user's management level is the second level, the boundary distance measurement method is used for evaluation; when the user's management level is the third level, the center radius measurement method is used for evaluation.

[0074] Step S03: acquiring a corresponding supervision area according to the management level of the user, and judging whether the user leaves the corresponding supervision area according to the positional relationship between the user position and the corresponding supervision area.

[0075] Specifically, step S031 obtains adjacent marking points on the boundary of the supervision area corresponding to the user's management level, and determines the slope between the adjacent marking points and the first straight line equations. For example, the marking point A is calculated. i With A i+1 The slope K i , the calculation formula is K i =(Y i+1 -Y i ) / (X i+1 -X i );

[0076] Step S032: determine the second straight line equation according to the horizontal coordinate of the user's position, and calculate the intersection of each first straight line equation and the second straight line equation. For example, calculate the mark point A i With A i+1 The equation of the straight line between j The intersection point X between the straight line equations i * , the calculation formula is X i * =(Y j -Yi ) / K i +X i ;

[0077] Step S033, the intersection is subjected to threshold restriction in the horizontal axis direction to obtain a threshold interval. The threshold interval is used to regard the intersection points as the same intersection when they are within the interval. It can be understood that i * Perform threshold limiting, the threshold interval is (min(X i ,X i+1 ),max(X i ,X i+1 )), calculate the intersection point X after limiting the threshold i z , the calculation formula is: If X i z ∈(min(X i ,X i+1 ),max(X i ,X i+1 )), then X i z =X i * ,otherwise

[0078] Step S034, determining whether the horizontal coordinate of the intersection point is smaller than the horizontal coordinate of the user's position;

[0079] Step S035, if it is determined that the horizontal coordinate of the intersection point is smaller than the horizontal coordinate of the user position, determining a first amount by which the horizontal coordinate of the intersection point is smaller than the horizontal coordinate of the user position;

[0080] Step S036, if it is determined that the horizontal coordinate of the intersection point is not less than the horizontal coordinate of the user position, then determining whether the horizontal coordinate of the intersection point is greater than the horizontal coordinate of the user position;

[0081] Step S037, if it is determined that the horizontal coordinate of the intersection point is greater than the horizontal coordinate of the user position, determining a second amount by which the horizontal coordinate of the intersection point is greater than the horizontal coordinate of the user position;

[0082] Step S038, determining whether the first number and the second number are both odd numbers;

[0083] Step S039: if it is determined that both the first number and the second number are odd numbers, it is determined that the user has not left the corresponding supervision area;

[0084] Step S0310: If it is determined that the first number and the second number are not both odd numbers, it is determined that the user has left the corresponding supervision area.

[0085] Step S04: If it is determined that the user has left the corresponding supervision area, the user's departure distance is calculated, and the degree of departure is evaluated based on the departure distance, and the feedback is given to the supervisor.

[0086] It should be noted that when the user's management level is the first level, the steps of assessment using the prohibition of crossing boundaries method include:

[0087] Determine the user's location A j To the corresponding regulatory area boundary line (i.e., marking point A i With A i+1 The foot point A of the straight line between ji , its coordinate calculation formula is: X ji =((X i -X i+1 )^2×X j -(Y i+1 -Y i )×(X i -X i+1 )×Y j -(Y i+1 -Y i )×(X i+1 Y i -X i Y i+1 )) / ((Y i+1 -Y i )^2+(X i -X i+1 )^2), Y ji =((Y i+1 -Y i )^2×Y j -(Y i+1 -Y i )×(X i -X i+1 )×X j -(X i -X i+1 )×(X i+1 Y i -X i Y i+1 )) / ((Y i+1 -Y i )^2+(X i -X i+1 )^2), and calculate each perpendicular point A ji With user location A j The straight-line distance L ji , the calculation formula is: L ji =sqrt((X j -X ji )^2+(Y j-Y ji )^2), the calculation result is in km, with an accuracy of three decimal places;

[0088] The shortest distance between each perpendicular foot point and the user's position is determined as the user's escape distance L ji * , the calculation formula is: when M j = "within the regulatory area", L ji * =0; when M j = "outside the regulatory area", it is equal to each L ji The minimum value in L ji * =min(L j1 ,L j2 ,…,L ji );

[0089] Determine whether the user's disengagement distance is 0;

[0090] If the user's disengagement distance is determined to be 0, the user's disengagement degree is determined to be no disengagement;

[0091] If it is determined that the user's disengagement distance is not 0, it is determined that the user's disengagement degree is severe disengagement.

[0092] When the user's management level is the second level, the step of using the boundary distance measurement method to perform evaluation includes:

[0093] Determine the foot point of the perpendicular line from the user location to the corresponding regulatory area boundaries, and calculate the straight-line distance between each foot point and the user location;

[0094] The shortest distance between each perpendicular foot point and the user's position is determined as the user's escape distance;

[0095] Determine whether the user's escape distance is less than or equal to a preset distance, where the preset distance is a fixed value, for example, the preset distance D=0.2, i.e., 200m;

[0096] If it is determined that the user's disengagement distance is less than or equal to the preset distance, the user's disengagement degree is determined to be moderate to light disengagement;

[0097] If it is determined that the user's disengagement distance is greater than the preset distance, the user's disengagement degree is determined to be severe disengagement. It is understandable that the evaluation supervision time T j When the supervised person's degree of disengagement is Z jn , the calculation method is: if L ji * =0, then Z jn = "No separation"; if L ji *∈(0, D], then Z jn = "moderate to mild detachment"; if L ji * >D, then Z jn = “Severe detachment”.

[0098] In this embodiment, when the user's management level is the third level, in the step of using the circle center radius measurement method to evaluate, the user's degree of separation is evaluated according to the user's situation in the supervision area and the outdoor activity safety area. Specifically, according to the user's location, the method in steps S031 to S0310 is used to evaluate the user's degree of separation, wherein the degree of separation is divided into three levels: "no separation", "moderately light separation", and "severe separation". Then Z1 = "no separation", Z2 = "moderately light separation", and Z3 = "severe separation". When falling within the outdoor safety activity boundary, M b = "In the outdoor activity safety area", otherwise M b = "Outside the outdoor activity area"; when M j = "within the regulatory area", and M b = "within the outdoor activity safety area", then Z jn = "No separation"; if M j = "within the regulatory area", and M b = "Outside the outdoor activity safety area", then Z jn = "moderate to mild detachment"; if M j = "outside the regulatory area", then Z jn = “Severe detachment”.

[0099] It should be noted that the process of determining the outdoor activity safety area includes:

[0100] Based on real-time user location A j and the user's residence location A0, determining the straight-line distance between the real-time user location and the user's residence location;

[0101] Calculate the outdoor activity distance R according to the supervision area j * , the calculation formula is: when M j = "Outside the regulatory area", R j * =0; when M j = "within the regulatory area", if R j * ≤0.1, R j * = 0, that is, within 100 meters of the residence, it is considered an indoor activity; when M j = "within the regulatory area", if R j * >0.1, R j* =R j ;

[0102] Filter the outdoor activity distances of the preset indicators to form a set, and calculate the mean and standard deviation of the set, that is, filter non-zero R j * Form a set R with q data q , calculate the average value of the set The calculation formula is The calculation formula of standard deviation σ is:

[0103]

[0104] According to the normal distribution of the data in the set, the data that does not meet the requirements are deleted to obtain the target set to improve the accuracy of determining the safe area for outdoor activities. It can be understood that, assuming that the set R q When the amount of data is large enough, it conforms to the normal distribution, and a 95% confidence interval is used. Delete the set R q Medium, greater than Data from outdoor activities to form a safe distance set R q * ;

[0105] Real-time user location A j Filter and remove points with consistent coordinates to obtain a set of outdoor activity safety marker points A z , where A j The straight-line distance R from A0 j ∈R q * , then filter A j Enter A z , otherwise do not enter;

[0106] According to the set of outdoor activity safety mark points, the boundary vertices of the outdoor activity safety area are determined, including:

[0107] Step 1: Calculate the target straight-line distance between each mark point in the outdoor activity safety mark point set and the user's residence location;

[0108] Step 2: Sort the target straight-line distances in descending order, and arrange the corresponding marked points according to the sorting results to form a target set, that is, {A1 * , A2 * …, A z *}, where A1 * A0 is the farthest from the residence of the supervised person, A2 * Secondly, and so on;

[0109] Step 3: The first marked point A1 in the target set * As the starting point, add it to the boundary vertex set with a preset number of requirements, and calculate the slope between the first marked point and each marked point in the target set. More specifically, in step 3.1, add A1 * As the starting point, filter the safe activity boundary vertex set B whose number of incoming data is t t , i.e. A1 * =B1; Step 3.2, calculate B1 to set A z * The slope K between each marked point z-1 , the calculation formula is K z-1 =(Y z * -Y1 * ) / (X z * -X1 * ), where z>1; Step 3.3, Assume A2 * For A1 * Start with the next vertex in the clockwise direction and calculate A2 according to step 3.2 * The slope between K1 and B1 is calculated. z-1 The angle θ between z-1 , the calculation formula is θ z-1 =arctan((K1-K z-1 ) / (1+K1×K z-1 ));

[0110] Step 4: Calculate the angle between the slopes, and determine a preset number of boundary vertices based on the angle between the slopes. More specifically, step 4.1: If all θ z-1 If both are ≥ 0, select A2 * Enter the safe activity boundary vertex set B as the second vertex t , i.e. A2 * =B2; Step 4.2, if all θ z-1 If all conditions are not ≥ 0, then A2 is abandoned. * , assuming A3 * For A1 * Start with the next vertex in the clockwise direction and calculate A3 according to step (4). * With A1 * The slope between K2 and K z-1 The angle θ between z-1 , the calculation formula is θ z-1 =arctan((K2-K z-1 ) / (1+K2×K z-1 )), if all θ z-1If both are ≥ 0, select A3 * Enter the safe activity boundary vertex set B as the second vertex t , i.e. A3 * = B2, and so on, until vertex B2 is found; Step 4.3, after vertex B2 is found, from set A z * Delete the marked points that have become vertices, repeat steps 3.2 to 4.2 until vertex B3 is found; step 4.4, after vertex B3 is found, repeat steps 3.2 to 4.3 until no vertex that meets the judgment conditions is found, then the last vertex that fully meets the judgment conditions is B t ; Step 4.5, set virtual marker point B t+1 , so that B t+1 Overlap with B1, that is, B i+1 coordinates = B1 coordinates;

[0111] Step 5: Connect each boundary vertex with a line segment to obtain the outdoor activity safety area. Starting from the starting point B1, connect the marked points B t With B t+1 , forming a closed polygon. The area inside the polygon is the outdoor safety activity jurisdiction, and the lines between the marked points are the boundaries of outdoor safety activities.

[0112] It should be noted that when Z jn = “No escape”, the supervised person’s activity area is normal; when Z jn = "moderate to mild separation", triggering system warning, M t = During “normal management”, use the external loudspeaker to call on the supervised personnel to return to the safe area as soon as possible; M t = "relaxed management", remind the supervised personnel by sending text messages or phone calls to return to the safe area as soon as possible; when Z jn =When the person is “severely out of control”, the system warning is upgraded and the staff of the rehabilitation institution is dispatched to bring back the supervised person based on the real-time positioning of the smart bracelet.

[0113] In summary, the user positioning supervision method with customizable jurisdiction in the above-mentioned embodiments of the present invention sets various types of supervision areas and obtains the user's location through a positioning device worn by the user; determines the user's management level based on the user's IQ assessment results and ADL self-care ability assessment results; obtains the corresponding supervision area based on the user's management level, and determines whether the user is out of the corresponding supervision area based on the positional relationship between the user's location and the corresponding supervision area; if it is determined that the user is out of the corresponding supervision area, calculates the user's departure distance, and evaluates the degree of departure based on the departure distance, and feeds back to the supervisor, which can reduce the workload of medical staff while strengthening supervision.
