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; 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; 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; 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; Step S400: reminding the user of the dryer. After receiving the reminder message, the user controls the dryer to the corresponding position interval again and restores the dryer to the previous heating power. Step S500: Calculate the working efficiency value of the dryer according to the heating power and air supply power of the dryer. When it is detected that the dryer is far away from the target object, keep the working efficiency value of the dryer unchanged and increase the air supply power of the dryer.

[0006] Furthermore, step S100 includes: Step S101: Set the initial angle of the first reference axis, which is parallel to the horizontal direction, set the sampling time t0, and record the position of the dryer once every t0 time interval. The position includes the angle between the first reference axis and the horizontal direction and the distance between the dryer and the object to be blown. The kth recorded position of the dryer is M k , M k (d k ,θ k ), d k Indicates the distance between the dryer and the object being blown, θ k Represents the angle between the first reference axis of the dryer and the horizontal direction; Step S102: Taking the position of the object to be blown as the coordinate origin, a plane coordinate system is established, the positions of the dryers are collected several times, and they are marked in the plane coordinate system to obtain the corresponding point of each dryer position in the plane coordinate system; Step S103: performing curve fitting on the points in the plane coordinate system to obtain a first target curve.

[0007] Further, step S200 includes: Step S201: Obtain the inflection points of the first target curve, connect all the inflection points with the coordinate origin in the plane coordinate system, and divide the first target curve into a number of curve segments, wherein the first target curve L is divided into i curve segments, respectively represented by l1, l2, l3, ..., and l i represents the first, second, third, ..., and i-th curve segments; The inflection point is a mathematical inflection point, also known as an inflection point. In mathematics, it refers to the point where the curve changes its upward or downward direction, that is, the dividing point between the concave arc and the convex arc of the continuous curve. The inflection point is selected in the scheme to extract the changing properties of the dryer motion trajectory; Since the hair density in different areas of the head is different, the angles and distances of users in different areas are also different when using the dryer. By fitting multiple usage records of the same user, the motion curve of the hair dryer that conforms to the user's usage habits is obtained; Step S202: Divide the plane coordinate system into a number of sectors according to the connecting line between the inflection point and the origin of the coordinate system, and use c1, c2, c3, ..., and c4 to correspond to the sectors where the curve segment is located according to the position of the curve segment in the plane coordinate system. irepresents the first, second, third, ..., and i-th sector-shaped areas, wherein the i-th curve segment is matched to the i-th sector-shaped area; Step S203: In any sector area, obtain the corresponding points of the positions of two consecutive dryers, and record them as M and M respectively according to the order of recording. j (d j ,θ j ) and M j+1 (d j+1 ,θ j+1 ), when d j >d j+1 When d j <d j+1 When the dryer is judged to be moving backward, M j Set as the starting point for forward or backward movement, M j+1 Set as the end point of forward or backward movement, and set any M j →M j+1 Construct a motion record of the dryer moving forward or backward, using (d j , d j+1 ) indicates the motion range corresponding to a motion record; When the heating power is constant, the dryer moves backward, which means that the user feels uncomfortable due to the high temperature of the hot air, so the dryer is moved away. The area boundary is formed by capturing the dryer's backward movement several times. When the dryer crosses the area boundary and is too close to the hair or skin, it will cause discomfort to the hair or skin. Step S204: when the dryer is in a working state of a certain heating power, the motion records of the p-bar dryer moving forward are merged into the first motion set H1, and the motion records of the q-bar dryer moving backward are merged into the second motion set H2; Step S205: Obtain any motion record r1 of the dryer moving forward in H1, where the distance between the motion starting point and the coordinate origin in r1 is d r1 , obtain a motion record r2 of the dryer moving backward in H2, where the distance between the starting point of the motion and the origin of the coordinate system in r2 is d r2 , satisfying the condition d r2 >d r1 When , r1 and r2 form an exclusion pair e, collect all the exclusion pairs to form an exclusion pair set E0, the forward motion records of all dryers in E0 form a set E1, and the backward motion records of all dryers in E0 form a set E2; Step S206: Calculate the motion set G, where G = (H1-E1) ∪ (H2-E2), using g1, g2, g3, ..., and g nThe first, second, third, ..., and nth motion records in G are represented by u1, u2, u3, ..., and u n Denote the motion range corresponding to the 1st, 2nd, 3rd, ..., nth motion records, and calculate the total motion range U of the dryer at the above heating power, U = u1 ∩u2 ∩u3 ∩ ... ∩u n ; The total range of motion determines the appropriate range of the dryer, within which the position of the dryer is considered appropriate, and the range of motion is determined by the intersection of the backward motion record and the forward motion record; In the actual sampling process, there are samples where the distance from the starting point of the backward movement to the coordinate origin is greater than the distance from the starting point of the forward movement to the coordinate origin. Such samples cannot determine the attributes of the boundary when calculating the boundary of the total movement range. That is, when the dryer is at the boundary of the movement range, the direction of the "movement area" cannot be determined. Therefore, it is necessary to eliminate contradictory samples. This solution adopts the method of finding contradictory pairs, "d r2 >d r1 When , r1 and r2 form an exclusion pair e", e represents a contradictory sample record pair, and this contradictory sample record pair is removed from the sample, so that the "total motion range direction" represents the consistency of the region; Step S207: Calculate the total range of motion corresponding to the heating power when the dryer is in the working state of any heating power, and arrange the total range of motion corresponding to each heating power from low to high according to the heating power of the dryer.

[0008] Furthermore, step S300 includes: Step S301: Obtain the sector area C where the current dryer is located a and the current heating power of the dryer W a , get W a In C a The corresponding range of motion U a , will U a Set as the monitoring range, the distance d between the current dryer and the coordinate origin a ; Step S302: Get U a The distance B between the nearest boundary and the origin of the coordinate system ai , when the dryer is not in U a Within the range of a1 >d a When d a Corresponding total range of motion U x , where B x1 <d a <Bx2 , B x1 Indicates U x The distance between the nearest boundary to the origin of the coordinate system and the origin of the coordinate system, B x2 Indicates U x The distance between the boundary farthest from the coordinate origin and the coordinate origin; Step S303: Obtain U x Corresponding heating power W x , change the current heating power of the dryer from W a Adjust to W x .

[0009] Furthermore, step S400 includes: Step S401: Set a time threshold t0. When the dryer is within the time range t0, x Back to U a In the middle, reduce the heating power of the dryer from W x Adjust to W a ; Step S402: When the dryer does not start from U within the time range t0 x Back to U a When x As the next monitoring scope.

[0010] Wherein, step S500 includes: Step S501: Get U a The distance B between the boundary farthest from the coordinate origin and the coordinate origin a2 , when the dryer is not in U a Within the range of a2 <d a When d a Corresponding total range of motion U y , where B y1 <d a <B y2 , B y1 Indicates U y The distance between the nearest boundary to the origin of the coordinate system and the origin of the coordinate system, B y2 Indicates U y The distance between the boundary farthest from the coordinate origin and the coordinate origin; Step S502: Obtain the current air supply power Q of the dryer a , get U y Corresponding heating power W y , calculate the target work efficiency value F y , F y =W y ×η a , where η aIndicates the ratio of the current blowing air supply power to the maximum air supply power of the dryer, and the calculated target air supply power ratio of the current dryer η * , η * =(W y / W a )×η a , η * ≤1; Step S503: Increase the air supply power of the dryer from Q a Adjust to η * ×Q max , where Q max Indicates the maximum air supply power of the dryer; During the drying process, the wind speed is the most important factor that can improve the drying efficiency. When the user holds the dryer away from the head, it means that the user does not feel the lack of hot air from the dryer. At this time, the drying efficiency of the dryer decreases due to the increase in the distance from the dryer, so the air supply power is increased to compensate for the loss of the drying efficiency of the dryer. In order to better implement the above method, a system for dynamically adjusting the operating state of a dryer is also proposed, the system comprising: A motion trajectory management module, an area management module, a heating power management module, a detection module and an air supply power management module, wherein the motion trajectory management module is used to manage the trajectory of the dryer, the area management module is used to manage the working range of the dryer in different areas, the heating power management module is used to adjust the heating power of the dryer, the detection module is used to detect whether the heating power of the dryer is restored, and the air supply power management module is used to adjust the air supply power of the dryer; Furthermore, the motion trajectory management module includes: a position acquisition unit, a position information management unit and a curve fitting unit, wherein 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 coordinates, and the curve fitting unit is used to fit the position information of the dryer; Further, the area management module includes: a motion recording unit, a motion range management unit and an arrangement unit, wherein 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; Furthermore, the heating power management module includes: a motion detection unit and a heating power adjustment unit, wherein the motion detection unit is used to detect the current motion state of the dryer, and the heating power adjustment unit is used to adjust the heating power of the dryer; Furthermore, the air supply power management module includes: a motion range acquisition unit, a target air supply power calculation unit and an air supply power adjustment unit, wherein the motion range acquisition unit is used to acquire corresponding motion range information, the target air supply power calculation unit is used to calculate the target air supply power, and the air supply power adjustment unit is used to adjust the air supply power of the dryer.
