In the embodiment of the invention, the dimming system is suitable for an advertisement putting screen, an information propaganda screen, a commodity display screen, a light show, a park garden lamp control and the like, and has wide application prospect. For convenience of understanding and explanation, in the embodiment of the present invention, the dimming and scene control of the advertisement delivery screen are described as an example.
According to a first aspect of the present invention, there is provided a flowchart of a dimming method based on a flow rate of people and location information, as shown in fig. 1, including:
step S101: acquiring the traveling information of the mobile terminal, matching the traveling information with the earth surface grid coordinates in the coverage area, and determining the grid position corresponding to the mobile terminal.
In the embodiment of the invention, a ground surface grid coordinate system can be established in the lamplight radiation area, the range of the ground surface grid coordinate system is only in the cross detection range of the wireless signal probe, and the cross detection range can be basically the same as that of the lamplight radiation area and is called as a coverage area.
The ground surface horizontal plane of the coverage area can be divided into rectangular grids which have the same size and are arranged in order, and the probe signal intensity of four corners of each rectangular grid is detected and used as a judgment coordinate of the rectangular grid in a ground surface grid coordinate system; it can be understood that when the probe detects the probe signal strength of any one mobile terminal, the grid position where the mobile terminal is located can be determined.
The judgment coordinates of each rectangular grid can be linearly arranged, so that earth surface grid coordinates of the whole coverage area are formed, and the position information of the earth surface grid coordinates of the current light radiation area is uploaded to a server; it can be understood that after the determination coordinates of the rectangular grid are linearly arranged, the virtual positions and the physical positions of the determination coordinates can be mapped one by one, and the complete rectangular grid structure of the coverage area can be pieced together according to the determination coordinates to form a ground surface grid coordinate system of the coverage area. The position information of the current coverage area and the earth surface grid coordinate information can be uploaded to the server together after being associated, so that the light control area where the mobile terminal is located can be determined quickly.
In the embodiment of the invention, the wireless signal probe can be erected in a large-scale lamplight radiation area, the detection range of the probe covers the lamplight radiation area, cross detection can be formed, the MAC address of the mobile terminal is obtained as the unique identification code, and the uniqueness of the mobile terminal is confirmed. And acquiring the received signal intensity of the mobile terminal to form cross detection, thereby determining the relative distance between the mobile terminal and each probe point position, determining the relative position, and matching with the earth surface grid coordinate system.
It can be understood that the wireless signal probe can adopt a WIFI probe technology, and the mobile terminal can acquire the MAC address and the signal strength without being connected with WIFI; the probe signal intensity data of each mobile terminal is not less than three.
It is understood that the mobile terminal may automatically turn on the WiFi of the mobile terminal after detecting the presence of signals from WiFi probes in the surroundings.
In the embodiment of the invention, after the wireless signal probe is erected in the coverage area and the virtual earth surface grid coordinate system is established, the traveling information of the mobile terminal in the coverage area can be detected. The travel information includes MAC address, cross signal strength, travel direction.
When the wireless signal probe detects that the mobile terminal enters the coverage area, acquiring the probe signal strength and the MAC address of the mobile terminal to form a sampling coordinate with uniqueness of the mobile terminal; it can be understood that the sampling coordinates include the strength of the cross detection signal of the mobile terminal, and the position determination can be performed with the determination coordinates of the grid; the MAC address information can ensure the uniqueness of the mobile terminal.
Matching the sampling coordinates with the surface grid coordinates to determine the grid position and the travel track of the mobile terminal in the coverage area; it can be understood that after the probe acquires the cross probe signal of the mobile terminal, the cross probe signal can be matched with the earth surface grid coordinate system, so as to determine the grid position where the mobile terminal is located; further, by continuous detection for a period of time, the travel track of the mobile terminal can be obtained, so that the travel direction of the person is reflected.
It will be appreciated that the probe information of the wireless signal probe may also include phase information, ensuring accuracy of the determination.
It can be understood that in the earth surface grid coordinate system, the smaller the area of each grid is, the more accurate the positioning is, but because the detection intensity of the four corners of the grid has errors, the area of the grid should not be too small, and in actual application, the grid division is performed with the basic requirement of being capable of clearly distinguishing the coordinates of the four corners.
Step S102: and dividing the mobile terminal in the coverage area into different clusters, acquiring a boundary grid of the clusters, and performing area expansion according to the boundary grid to form a control area.
In the embodiment of the invention, the distribution of the mobile terminals in the coverage area has randomness and mobility, so that the mobile terminals need to be divided into different clusters, and the clusters with different numbers are controlled independently and distinctively. Specifically, the screen brightness, the content of the delivery, the frequency, and the like can be represented.
Dividing the mobile terminals in the coverage area into different clusters specifically comprises:
predefining a continuity decision value; the method is used for judging the continuity among the mobile terminals, and is convenient for dividing clusters.
Predefining a refresh time; based on the mobility of the people, the division of the cluster needs to be refreshed in time, and the refreshing frequency can be counted in seconds.
In the linearly arranged grids, judging whether the grid positions of all the mobile terminals have continuity, specifically comprising the steps of:
s11: detecting grid positions of all mobile terminals in the coverage area;
s12: taking one mobile terminal in the coverage area as a base point, calculating a distance value between the base point and other adjacent mobile terminals, and judging whether the distance value is greater than the continuity judging value; selecting one mobile terminal in a coverage area as a base point, performing continuity extension judgment, dividing a cluster, calculating a distance value between the base point and other mobile terminals adjacent to the base point, wherein the distance value between the mobile terminal and the base point meets a basic condition of continuity judgment, the base point and the mobile terminal can be considered to be continuous, and meanwhile, a plurality of adjacent mobile terminals around the base point are calculated, so that the cluster can be divided quickly. It is understood that two mobile terminals can be determined to be continuous without being located in two adjacent grids, and the continuity determination may be performed by comparing the distance values according to the continuity determination value.
S121: if the distance value is not greater than the continuity judgment value, the method has continuity and is divided into the same cluster; if the distance between two mobile terminals is short and continuity can be determined, the two mobile terminals can be classified into the same cluster.
S122: if the distance value is larger than the continuity judging value, the continuity is not achieved, and two clusters are divided; if the distance between the two mobile terminals is large and it can be determined that there is no continuity, two different clusters can be divided.
S13: combining two clusters of any mobile terminal with two cluster partitions into one cluster, switching the next mobile terminal to be used as a base point, and repeating the step 12 until all the mobile terminals are partitioned into the clusters; when the cluster division calculation is repeatedly performed, different base points can be selected, and the next base point is distinguished from the current base point. When two different cluster partitions exist in a mobile terminal, the two clusters can be considered to have continuity, and can be combined into one cluster.
S14: after one of the refresh times, the cluster is subdivided, and the step S11 is returned; based on the real-time mobility of the personnel, the cluster division is refreshed at a certain frequency, so that the cluster also has certain mobility, and the mobility condition of the personnel is reflected more truly.
It is understood that other mobile terminals adjacent to the base point can be selected as the next base point, but the calculation at this time is more repeated and is not computationally intensive. A base point selection rule can be set, small areas are divided regularly in a certain area, a base point is selected at the center position of each small area, the base point selection and the distance calculation can be carried out by multiple lines at the same time, then the multiple cluster division of the mobile terminal is combined, and clusters with continuity are combined into the same cluster; and base point selection can be performed according to the density of the mobile terminal, one base point can be selected in each dense area, and a plurality of base points are distributed and selected in the scattered areas, so that the efficiency of effective calculation is improved, and the waste of calculation power is reduced.
It can be understood that, based on the mobility of people, mobility also exists in the divided clusters, and the number of the mobile terminals included in the clusters increases or decreases, and when refreshing, only the clusters need to be distinguished, and whether the mobile terminals in the clusters are the same or not does not need to be distinguished.
It can be understood that, in the divided clusters, the grid position where the mobile terminal at the boundary position is located may be defined as a boundary grid, and the contour boundary of the cluster may be drawn by acquiring all the boundary grids of the cluster, where the contour is relatively irregular in shape, and is not beneficial to uniform control, but the contour boundary can relatively accurately describe the overall contour of the current cluster. Therefore, rectangular expansion can be performed according to the position information of the boundary grid, and the outline of the cluster is expanded into a rectangle, so that the outline boundary of the cluster is a rectangle and is a relatively regular shape, but the rectangular outline cannot accurately describe the whole outline of the current cluster, and belongs to interference expansion. Compared with the outline boundary which is described accurately and is not expanded, when the density of the mobile terminals in the cluster is increased, the space in the rectangular outline is sufficient for distributing the increased mobile terminals, so that the boundary of the rectangular outline after being expanded cannot generate continuous change in a short time, and the time effectiveness of unified control is prolonged.
In the embodiment of the present invention, the forming the control area by performing area expansion on the grid according to convenience specifically includes:
predefining an extension upper limit value; and dividing an expansion upper limit value, wherein the expansion upper limit value can be changed in a floating manner according to the control range of the controller so as to meet the principle that the control range of the controller is completely in the control area.
Acquiring the grid position of the mobile terminal at the cluster boundary position according to the cluster division of the mobile terminal; it can be understood that the cluster is a relatively loose temporary integral structure, the boundary position is defined as the outer edge of the cluster, and the mobile terminal and the contour boundary at the boundary position can be obtained by performing the tracing connection.
Defining the grids of the mobile terminals at the cluster boundary positions as boundary grids; the grid of the cluster boundary position is a boundary grid, and can be used for performing stroking and connecting lines, so that irregular contour boundaries are obtained.
The boundary grids of each cluster are subjected to rectangular expansion outwards to form a control area; it can be understood that the boundary grid of the cluster is expanded to the outside in a rectangular manner, so that all the mobile terminals of the current cluster are in the rectangular frame after expansion, and the rectangular area after expansion is defined as the control area.
The control area is rectangular, four sides of the rectangle are expansion boundaries, and the control area is always located in the coverage area; it can be understood that each cluster is a rectangle after being expanded, four sides of the rectangle are boundaries after being expanded, but a control area of the rectangle is always in a coverage area, and a part beyond the coverage area can be directly discarded.
In the process of performing rectangular expansion on the control area, the shortest distance between the boundary grid and the expansion boundary of each cluster is greater than the expansion upper limit value; it is understood that, in order to prevent omission of the framing range of the rectangular frame in a single cluster, an extension upper limit value may be set, and the shortest distance (which may be with ± sign) between the boundary grid of the cluster and the extension boundary is calculated, and the value of the extension upper limit value should always be smaller than the shortest distance.
It will be appreciated that the distance between the boundary mesh of the cluster and the expanded boundary may be calculated by the decision coordinates of the mesh.
It can be understood that when the control area is expanded, the control area has interference expansion, so that the flow of personnel in the coverage area can be indirectly guided, and the display of visual information is facilitated. Therefore, the resident range of the personnel can be enlarged, and the reasonable utilization of resources is facilitated.
In the embodiment of the invention, in the lighting system, each controller can independently control one advertisement putting screen, and based on the size of the screen, the lighting radiation range can be correspondingly obtained, and the lighting radiation range is matched with the ground surface grid coordinate in the ground surface grid coordinate system to obtain an optimal viewing area and a ground surface grid area of the optimal viewing area. The grid area of the ground table can be used as the control range of the controller, when the control range is covered by the control area, the controller is brought into unified control, and the unified control is carried out on the controller corresponding to the control range covered by the control area, so that the content and the brightness of the advertisement putting screen are controlled in a unified way, and the resources are effectively utilized.
The method specifically comprises the following steps:
matching the light radiation range controlled by each controller with the ground surface grid coordinates;
acquiring a ground surface grid area of an optimal viewing area of a light scene controlled by each controller;
and the controllers of the lighting systems corresponding to each earth surface grid area contained in the control area are all subjected to unified control, so that the unified control of lighting scenes in the current control area is realized.
Step S103: and when the distance between the expansion boundaries of any two control areas is smaller than the merging critical value, merging control is carried out, and the two control areas are classified into the same control area.
In the embodiment of the invention, after each cluster is subjected to rectangular expansion, the boundary of the cluster is changed, and the possibility of existence of continuity is changed into the existence of unified control possibility, so that the coverage range of a control area needs to be judged again, unified control classification and combination are carried out, and the multi-path load of the system is reduced.
In the embodiment of the present invention, the merging control between the control areas specifically includes:
after finishing the boundary extension of the clusters, forming independent control areas of a single cluster, and judging whether to carry out combination control according to the distance between the extension boundaries of the control areas; it is understood that the cluster boundaries after expansion may have a certain range of proximity, overlap, etc., and a combination control may be performed to perform a unified control on the controllers in the two control areas.
The merge control includes the steps of:
s21: predefining a merging critical value and predefining merging detection time; it can be understood that, when the control areas are merged, a determination standard is needed, so that a merging critical value can be formulated to determine whether merging control is needed; based on the mobility of people, the mobility of the control area exists, and whether the control area in the current coverage area needs to be combined or not can be judged again after one-time advertisement putting is completed, so that the combining detection time can be set as the combining detection frequency, and the combining detection frequency can be measured in minutes.
S22: calculating a distance value between the expansion boundaries between two adjacent control areas, and judging whether the distance value is smaller than the merging critical value;
s221: if the distance value is smaller than the merging critical value, merging the two control areas and classifying the two control areas into the same control area; the expansion boundaries of the two control areas are close to each other or overlap with each other, and can be subjected to combined control to perform unified control on the controllers in the two control areas
S222: if the distance value is not smaller than the merging critical value, independent control is still performed; the extended boundary distance of the two control areas is far, so that the combined control is not needed, and the independent control between the areas is still maintained.
S23: after one of the merging detection times has elapsed, recalculating the pitch value, returning to step S22; it is understood that after a merging detection time has elapsed, whether there is a possibility of merging in the control area in the currently covered area should be newly determined based on the mobility of the person.
It is understood that, when returning to step S22, since the update frequency of the clusters is significantly faster than the detection frequency of the control area, the latest cluster division and the latest control area extension boundary can be obtained and used directly.
It can be understood that, when the cross-region combination is performed, the boundary distance calculation between a plurality of adjacent regions can be performed simultaneously, so that the combination control can be completed quickly, the combination control can be performed continuously, and the control regions meeting the conditions are classified into the same control region.
In the embodiment of the present invention, after the partition of the cluster is updated, the control area expansion may not be performed temporarily, and the expansion frequency of the control area may be set corresponding to the update frequency of the control area, so that the latest control area expansion boundary can be obtained each time the step S22 is returned, instead of performing rectangular expansion each time along with the update frequency of the cluster, thereby reducing power consumption.
Step S104: and acquiring the effective number of residents in each control area, and switching scenes of the lighting system corresponding to the control area when the effective number of residents is greater than a threshold value.
In the embodiment of the invention, when the mobile terminal is detected to enter the coverage area, the MAC address of the mobile terminal can be simultaneously acquired as the unique identifier; and acquiring a timestamp of the mobile terminal to identify the entry time of the mobile terminal, and acquiring the travel time of the mobile terminal in the coverage area according to the cluster high-frequency refreshing data. In the corresponding control area, the travel track and the travel time of a single mobile terminal can be obtained, so that whether people reside is judged, the resident information of the mobile terminal in the whole control area is counted, the effective resident number can be obtained, and the corresponding scene control effect is triggered.
Normal travel time can be calculated according to the extended boundary of the rectangle, so that comparison is generated, and residence information is judged; further, real-time traveling speed can be carried out according to the traveling track and the time stamp of the mobile terminal, so that the resident information is judged; therefore, a residence time can be set for comparison to judge whether the personnel in the control area have residence conditions or not, and scene control is carried out.
The step of obtaining the number of residents in each control area specifically comprises the following steps:
a predefined residence time; the standard value of the personnel residence judgment can be changed.
Detecting the number of MAC addresses of the mobile terminals in each control area; the number of unique MAC addresses is obtained, reflecting the number of people in the control area.
And calculating the traveling time of the mobile terminal corresponding to each MAC address in the control area.
Determining whether the travel time is greater than the dwell time; and comparing the time with the residence time to judge the residence information.
If the travel time is not greater than the residence time, the user using the mobile terminal does not reside; the explanation personnel do not have the phenomenon of staying, only pass by, can not receive the advertisement delivery of visual information, only can hear the advertisement delivery of broadcast type.
If the travel time is longer than the residence time, using the user residence of the mobile terminal as effective residence; the explanation personnel have the stay phenomenon, can receive the advertisement putting of visual information, have the value of putting.
Counting the number of effective resident persons in the control area; and counting the number of effective resident people in the control area, so as to switch corresponding scene control, and switch different scenes according to the threshold value reached by the number of people, thereby improving the effectiveness and accuracy of advertisement delivery and maximizing the profit.
In the embodiment of the invention, the threshold value of the effective resident number in the control area can be divided into multiple stages, and the control effect is corresponding to different scenes. In different control areas in the same coverage area, if the number of the residents in the coverage area reaches a certain threshold value, the unified control of the whole area can be carried out, and large-scale scene switching can be carried out.
The control authority of a single control area can be defined as a secondary authority, the control authority of a coverage area can be defined as a primary authority, and the primary authority can be the secondary authority below or can be temporarily closed.
The number of effective residents in the control area can be defined as a first threshold value, and scene switching reaching the first threshold value is defined as a secondary lighting scene; and defining the effective number of residents in the coverage area as a second threshold value, and defining the scene switching reaching the second threshold value as a primary light scene. And defining the light scene when the number of the effective resident persons in the control area does not reach the first threshold value as a three-level light scene.
For the switching of the secondary lighting scenes in the single control area, the method specifically comprises the following steps:
predefining a first threshold value and predefining a switching time length;
the secondary lighting scene switching comprises the following steps:
s31: obtaining the number of effective residents in the current control area, and judging whether the number of the effective residents is greater than the first threshold value or not;
s32: if the number of the effective residents is larger than the first threshold value, switching the lighting scene corresponding to the current control area to the secondary lighting scene;
s321: detecting the duration of a secondary lighting scene corresponding to the current control area, and judging whether the duration is greater than the switching duration;
s322: when detecting that the duration is greater than the switching duration, returning to step S31;
s33: and if the number of the effective residents is not more than the first threshold value, switching the light scene corresponding to the current control area to a three-level light scene.
It can be understood that scene switching in a single control area changes with the number of effective residents in the control area, and the switching time can be measured in minutes, so that the number of effective residents in the next time is determined after the complete advertisement delivery group can complete delivery. With this circulation, effective putting of the advertisement is carried out according to the number of resident persons, and the attention of passing persons can be attracted.
It can be understood that the switching duration can be temporarily changed to optimize advertisement delivery. A plurality of advertisement contents can be delivered within the duration time of one secondary lighting scene, the effective number of residents changes, when the number of the residents is lower than a threshold value, the switching time length can be changed temporarily, the duration judgment time length of the secondary lighting scene is shortened, and when the currently played advertisement is finished, the scene switching judgment is carried out, namely after the delivery of the last advertisement within the duration time of the secondary lighting scene is finished, the scene switching judgment is carried out. The putting duration of the secondary lighting scene in the control area and the refreshing frequency of the control area can be synchronously carried out.
In the embodiment of the invention, the release time of a single advertisement can be calculated, the remaining time can be obtained, when the effective number of resident people is detected to be reduced below the first threshold value, the continuous reduction judgment of the number of resident people is executed, a lag time is set, whether the effective number of resident people is continuously reduced or not is monitored in the lag time, if the effective number of resident people is continuously reduced, the scene switching can be directly carried out, and if the effective number of resident people is not continuously reduced, the scene switching is not carried out continuously, and the refreshing of the control area is waited.
And in the duration of the secondary lighting scene, the lighting system corresponding to the current control area responds to the switching instruction of the primary lighting scene of the coverage area, namely the switching instruction of the primary authority can cover the switching instruction of the secondary authority, so that the controllers of the lighting systems in the whole coverage area are controlled in a unified manner.
The switching of the primary lighting scenes in the coverage area specifically comprises the following steps:
predefining a second threshold value, and predefining a refreshing time length;
the primary light scene switching comprises the following steps:
s41: acquiring the effective number of residents in all control areas in the coverage area, and judging whether the effective number of residents is greater than the second threshold value;
s42: when the number of the effective residents is larger than the second threshold value, closing the control right of the secondary lighting scene in each single control area, and switching the lighting scene in the whole coverage area to the primary lighting scene;
s421: detecting the duration of the primary lighting scene in the coverage area, and judging whether the duration is greater than the refreshing duration;
s422: when the duration is longer than the refresh duration, returning to step S41;
s43: and when the number of the effective residents is not larger than the second threshold value, transferring the control right of the secondary lighting scene in each single control area, and not switching the primary lighting scene in the coverage area.
It can be understood that the primary lighting scene is the unified control of the whole coverage area, and the attention of passing personnel can be actively attracted aiming at the advertisement putting effect with macro setting, so that the advertisement putting is effective and the income is high. For the secondary lighting scene, only a small number of crowds in the single control area can be targeted to the advertisement putting effect with a normal form, and the advertisement is put by resident persons and passers-by persons. For the three-level light scene, the advertisement putting aiming at the condition that the number of effective resident persons is less or no number of effective resident persons can reduce the putting frequency, set up interesting elements and attract persons to reside.
It will be appreciated that the light scene at each level, corresponding to a range of illumination intensities, may be adapted.
It will be appreciated that the second threshold is greater than the first threshold. The first threshold is specific to a single control area, and the second threshold is a true whole coverage area, so that when the coverage area is large enough, the numerical value of the second threshold should be large enough, and therefore, an adjustment window needs to be reserved for the first threshold and the second threshold, so as to facilitate updating and adjustment.
