Description

Technical Field

[0001] The present invention relates to the technical field of dryer control, and in particular to a system and method for dynamically adjusting the operating state of a dryer. Background Art

[0002] The dryer is composed of a set of electric heating wires and a small high-speed fan. When powered on, the electric heating wires will generate heat, and the wind blown by the fan will become hot air after passing through the electric heating wires. The hot air removes moisture to increase the speed of air drying. In daily life, the widely used hair dryer is a type of dryer, and the hair dryer can be regarded as a handheld dryer.

[0003] However, improper use of a hair dryer can cause damage to the hair. For example, when the hair dryer is too close to the skin, it is easy to burn the skin. When the hair dryer is too close to the scalp, the high-temperature hot air causes irreversible damage to the hair follicles. The prior art lacks a method for adjusting the hair dryer when the user holds the hair dryer too close to the hair during use. Summary of the invention

[0004] The purpose of the present invention is to provide a cross-border e-commerce intelligent logistics operations data analysis system and method to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a method for dynamically adjusting the operating state of a dryer;

[0006] Step S100: For a handheld dryer having a plurality of heating power gears and air supply power gears, a first reference axis is provided, the first reference axis is parallel to the air outlet direction of the dryer, and the trajectory of the dryer is captured during the user's use, and a plurality of trajectory records are obtained, and fitted into a first target curve;

[0007] Step S200: Divide the first target curve into several parts according to the angle, establish a plane coordinate system, divide the plane coordinate system into several sector areas according to the angle, capture the historical records of the forward and backward movement of the dryer at the same heating power in each sector area, and determine the working range of each heating power level of the dryer in different sector areas;

[0008] Step S300: obtaining the distance between the current dryer and the origin of the plane coordinate system and the sector area where the dryer is located, and obtaining the working range of the dryer in the sector area, setting the object of the current dryer's blowing as the target object, and reducing the heating power of the dryer when it is detected that the dryer is close to the target object;

[0009] Step S400: Remind the user of the dryer. When the user receives the reminder message, re-control the dryer to the corresponding position range and restore the heating power of the dryer to the previous level.

[0010] Step S500: Calculate the working efficiency value of the dryer based on the heating power and the air supply power of the dryer. When it is detected that the dryer is far from the target object, keep the working efficiency value of the dryer unchanged and increase the air supply power of the dryer.

[0011] Further, step S100 includes:

[0012] Step S101: Set the initial angle of the first reference axis, where the initial angle is parallel to the horizontal direction. Set the sampling time t0, and record the position of the dryer every t0 time. The position includes the angle between the first reference axis and the horizontal direction and the distance between the dryer and the object being blown. Among them, the position of the dryer recorded at the k-th time is M k ,M k (d k ,θ k ),d k represents the distance between the dryer and the object being blown, and θ k represents the angle between the first reference axis of the dryer and the horizontal direction;

[0013] Step S102: Use the position of the object being blown as the coordinate origin to establish a plane coordinate system. Collect the positions of the dryer several times and mark them in the plane coordinate system to obtain the corresponding points of each position of the dryer in the plane coordinate system;

[0014] Step S103: Perform curve fitting on the points in the plane coordinate system to obtain the first target curve.

[0015] Further, step S200 includes:

[0016] Step S201: Obtain the inflection points of the first target curve. In the plane coordinate system, connect all the inflection points to the coordinate origin, and divide the first target curve into several curve segments. Among them, divide the first target curve L into i curve segments, which are respectively represented by l1, l2, l3,..., and l i represent the 1st, 2nd, 3rd,..., and the i-th curve segments;

[0017] The inflection point is the inflection point in the mathematical sense, also known as the point of inflection. Mathematically, it refers to the point that changes the upward or downward direction of the curve, that is, the demarcation point between the concave arc and the convex arc of a continuous curve. In the solution, the inflection point is selected to extract the change property of the dryer's movement trajectory;

[0018] Due to the different hair densities in different regions of the head, when using a hair dryer, the angles and distances of the user for different regions are also different. By fitting the usage records of the same user multiple times, a movement curve of the hair dryer that conforms to the user's usage habits is obtained;

[0019] Step S202: According to the connection line between the inflection point and the coordinate origin, divide the plane coordinate system into several fan-shaped regions. Corresponding to the position of the curve segment in the plane coordinate system and the fan-shaped region where the curve segment is located, use c1, c2, c3, ……, and c i To represent the 1st, 2nd, 3rd, ……, and the i-th fan-shaped regions, where the i-th curve segment corresponds to the i-th fan-shaped region;

[0020] Step S203: In any fan-shaped region, obtain the corresponding points of the positions of two consecutive hair dryers. According to the recording sequence, they are respectively denoted as M j (d j ,θ j )and M j+1 (d j+1 ,θ j+1 ). When d j >d j+1 ,it is determined that the hair dryer moves forward. When d j <d j+1 ,it is determined that the hair dryer moves backward. Set M j as the starting point of the forward or backward movement of the hair dryer, and M j+1 as the ending point of the forward or backward movement of the hair dryer. Any M j →M j+1 constitutes a movement record of the hair dryer moving forward or backward, and is represented by (d j ,d j+1 ) to represent the movement range corresponding to a movement record;

[0021] When the heating power is constant, the backward movement of the hair dryer indicates the discomfort caused by the user feeling that the hot air temperature is too high. Therefore, move the hair dryer away. By capturing the backward movement of the hair dryer several times to form the regional boundary, when crossing the regional boundary and being too close to the hair or skin, it will cause discomfort to the hair or skin;

[0022] Step S204: When the hair dryer is in the working state of a certain heating power, incorporate p movement records of the hair dryer moving forward into the first movement set H1, and incorporate q movement records of the hair dryer moving backward into the second movement set H2;

[0023] Step S205: Obtain any movement record r1 of the hair dryer moving forward in H1. Among them, the distance between the starting point of the movement in r1 and the coordinate origin is d r1, obtain a certain motion record r2 of the dryer moving backward in H2, where the distance between the starting point of the motion in r2 and the coordinate origin is d r2 , satisfying the condition d r2 > d r1 When the condition is met, form a repulsion pair e with r1 and r2. Gather all the repulsion pairs to form a repulsion pair set E0. Form a set E1 with all the motion records of the dryer moving forward in E0, and form a set E2 with all the motion records of the dryer moving backward in E0;

[0024] Step S206: Calculate the motion set G, where G = (H1 - E1) ∪ (H2 - E2). Use g1, g2, g3,..., and g n to represent the 1st, 2nd, 3rd,..., and nth motion records in G respectively. The corresponding motion ranges of each motion record are represented by u1, u2, u3,..., and u n to represent the motion ranges corresponding to the 1st, 2nd, 3rd,..., and nth motion records respectively. Calculate the total motion range U of the dryer at a certain heating power, U = u1 ∩ u2 ∩ u3 ∩... ∩ u n ;

[0025] The total motion range determines the appropriate range of the dryer. It is considered that the position of the dryer is appropriate within the motion range. The determination method within the motion range is the intersection of the backward motion records and the forward motion records;

[0026] In the actual sampling process, there are samples where the distance from the starting point of the backward motion to the coordinate origin is greater than the distance from the starting point of the forward motion to the coordinate origin. Such samples will make it impossible to determine the attribute of the boundary when calculating the boundary of the total motion range. That is, when the dryer is at the motion range boundary, it is impossible to determine the direction of "within the motion area". Therefore, it is necessary to eliminate the contradictory samples. This solution adopts the method of finding the contradictory pairs. "d r2 > d r1 When the condition is met, form a repulsion pair e with r1 and r2", e represents a pair of sample records with contradictions. Remove this pair of sample records with contradictions from the samples to make the direction of the "total motion range" represent the consistency of the area;

[0027] Step S207: Calculate the working state of the dryer at any heating power. Calculate the total motion range corresponding to the heating power, and arrange the total motion ranges corresponding to each heating power according to the heating power of the dryer from low to high.

[0028] Furthermore, step S300 includes:

[0029] Step S301: Obtain the sector area C where the current dryer is located a and the heat generation power W of the current dryera , obtain W a In C a the corresponding movement range U a , set U a as the monitoring range, the distance d between the current dryer and the origin of coordinates a ;

[0030] Step S302: Obtain the distance B between the boundary closest to the origin of coordinates in U a and the origin of coordinates. When the dryer is not within the range of U a1 , and B a > d a1 , obtain d a corresponding to the total movement range U a , where B x < d x1 < B a , B x2 represents the distance between the boundary closest to the origin of coordinates in U x1 and the origin of coordinates, and B x represents the distance between the boundary farthest from the origin of coordinates in U x2 and the origin of coordinates; x ;

[0031] Step S303: Obtain the corresponding heating power W of U x , and adjust the heating power of the current dryer from W x to W a . x .

[0032] Furthermore, step S400 includes:

[0033] Step S401: Set the time threshold T1. When within the T1 time range, the dryer returns from U x to U a , adjust the heating power of the dryer from W x to W a ;

[0034] Step S402: When within the T1 time range, the dryer does not return from U x to U a , set U x as the next monitoring range.

[0035] Among them, step S500 includes:

[0036] Step S501: Obtain the distance B between the boundary farthest from the origin of coordinates in U a and the origin of coordinates. When the dryer is not within the range of U a2 , and B a ​a2 <d a When, obtain d a corresponding total movement range U y , where B y1 <d a <B y2 , B y1 represents the distance between the boundary closest to the origin of coordinates in U y and the origin of coordinates, B y2 represents the distance between the boundary farthest from the origin of coordinates in U y and the origin of coordinates;

[0037] Step S502: Obtain the current air supply power Q of the dryer a , obtain U y corresponding heating power W y , calculate the target working efficiency value F y , F y =W y ×η a , where η a represents the ratio of the current air supply power of the blowing to the maximum air supply power of the dryer. Calculate the target air supply power ratio η of the current dryer * , η * = (W y / W a ) ×η a , η * ≤1;

[0038] Step S503: Adjust the air supply power of the dryer from Q a to η * ×Q max , where Q max represents the maximum air supply power of the dryer;

[0039] During the drying process, the wind speed is the most effective in improving the drying efficiency. When the user holds the dryer away from the head, it means that the user does not feel a lack of hot air from the dryer in the current usage state. At this time, due to the increase in the distance of the dryer, the drying efficiency of the dryer decreases. Therefore, the air supply power is increased to make up for the loss of the drying efficiency of the dryer;

[0040] To better implement the above method, a dynamic adjustment system for the operating state of a dryer is also proposed. The system includes:

[0041] A motion trajectory management module, a region management module, a heating power management module, a detection module, and a blowing power management module. Among them, the motion trajectory management module is used to manage the trajectory of the dryer; the region management module is used to manage the working range of the dryer in different regions; the heating power management module is used to adjust the heating power of the dryer; the detection module is used to detect whether to restore the heating power of the dryer; and the blowing power management module is used to adjust the blowing power of the dryer.

[0042] Further, the motion trajectory management module includes: a position acquisition unit, a position information management unit, and a curve fitting unit. Among them, the position acquisition unit is used to acquire the position information of the dryer; the position information management unit is used to manage the position of the dryer in the plane coordinate; and the curve fitting unit is used to fit the position information of the dryer.

[0043] Further, the region management module includes: a motion recording unit, a motion range management unit, and an arrangement unit. Among them, the motion recording unit is used to record the motion of the dryer; the motion range management unit is used to manage the motion range of the dryer; and the arrangement unit is used to arrange the total motion range corresponding to each heating power.

[0044] Further, the heating power management module includes: a motion detection unit and a heating power adjustment unit. Among them, the motion detection unit is used to detect the motion state of the current dryer; and the heating power adjustment unit is used to adjust the heating power of the dryer.

[0045] Further, the blowing power management module includes: a motion range acquisition unit, a target blowing power calculation unit, and a blowing power adjustment unit. Among them, the motion range acquisition unit is used to acquire the corresponding motion range information; the target blowing power calculation unit is used to calculate the target blowing power; and the blowing power adjustment unit is used to adjust the blowing power of the dryer.

[0046] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention records the usage records of the dryer, sets the management area of the dryer, obtains the ranges corresponding to different heating powers in each management area, establishes the relationship between the operation of the dryer, the angle, and the distance from the head. When the dryer is too close to the head, the heating power of the dryer is reduced to protect the skin and hair of the user. When the dryer is too far from the head, the blowing power of the dryer is increased to supplement the drying efficiency of the dryer. Description of the Drawings

Among them, the position of the dryer recorded for the kth time is M k , M k (d k , θ k ), d k represents the distance between the dryer and the object affected by the blowing, and θ k represents the angle between the first reference axis of the dryer and the horizontal direction;

[0056] Step S102: Take the position of the object affected by the blowing as the coordinate origin to establish a plane coordinate system, collect the positions of the dryer for several times, and mark them in the plane coordinate system to obtain the corresponding points of each position of the dryer in the plane coordinate system.

When d j < d j+1 , it is determined that the dryer moves backward. Set M j as the starting point of the forward or backward movement of the dryer, and set M j+1 as the ending point of the forward or backward movement of the dryer. Any M j → M j+1 constitutes a movement record of the dryer moving forward or backward. Use (d j , d j+1 ) to represent the movement range corresponding to a movement record;
