in the formula I 1 Is the sole profile length, /) 2 For the length of the high-heeled shoe sole profile, l 3 For the length of the large shadow of the high-heeled shoe sole, H is the height of the person, g is the gravity coefficient, mu is the body density, and 1.02g/cm is taken 3 0.6G represents the weight of the body and the arm of the person, 0.4H represents the length of the body of the person, and therefore the cross-sectional area of the body of each person can be calculated to be the occupied area when the person takes the elevator;
in step S7, the simulation method of the elevator plan is:
s71, establishing a coordinate system by taking one corner of the elevator as a coordinate origin;
s72, establishing a rectangle in the positive direction of the coordinate system, wherein the length and the width of the rectangle are consistent with the size of the elevator and are used as an elevator plan;
s73, respectively reflecting the pressure distribution diagram to the diagram;
s74, respectively establishing an ellipse equation by taking the sole outline and the high-heeled sole outline as centers, and taking an ellipse as an occupied area of each person;
s75, directly taking the goods outline as a goods occupied area;
s76, connecting points of the outline of the trolley, selecting the longest line as the diameter, and drawing a circle by using the center of the outline of the trolley as an occupied area of the trolley;
s77, the calculation module calculates the crowdedness degree in the elevator according to all the occupied areas;
in the above step 77, the method of calculating the degree of congestion is to divide the elevator plan view into 4x4 small blocks, select 2x2 small block areas each time, divide 9 areas, divide the occupied areas in the respective areas, calculate the remaining area, calculate the overlapping area only once if there is an overlapping area, determine that the elevator is not congested if the remaining area is larger than the occupied area of 1.5 normal adults, and determine that the elevator is not congested if any one area in the elevator is determined to be not congested, otherwise determine that the elevator is not congested as a whole if all the areas in the elevator are determined to be congested, and determine that the elevator is congested as a whole if all the areas in the elevator are determined to be congested.
2. The intelligent and humanized elevator parking control system based on big data as claimed in claim 1, characterized in that: in step S74, the sizes of the major axis a and the minor axis b of the ellipse need to be calculated before calculating the ellipse equation, and the calculation formula is:
Figure 76316DEST_PATH_IMAGE004
。
3. the intelligent and humanized elevator parking control system based on big data as claimed in claim 2, characterized in that: the ellipse equation is:
Figure 590474DEST_PATH_IMAGE006
in the equation, X, Y represents the center coordinates (X, Y) of the sole profile or high-heeled sole profile, t represents the inclination angle between the direction perpendicular to the sole profile or high-heeled sole profile and the X-axis direction, and θ represents a coefficient, and the calculated elliptical profile represents the occupied area of each person.
4. The intelligent and humanized elevator parking control system based on big data as claimed in claim 3, characterized in that: in the steps S74-S76, the circle is used as the occupied area of the cart to ensure that there is enough space in the elevator for the person to take out the goods after arriving at the floor, and for the disabled person sitting in the wheelchair, there is enough space for the disabled person to turn the wheelchair, and if the disabled person uses the crutch, the disabled person is marked as the disabled person, and at this time, a circle of concentric ellipse with the crutch point as the major axis is added outside the occupied area of the disabled person, so that the disabled person using the crutch can also provide enough activity space.
