Description

Technical Field

[0001] The present invention relates to the field of terminal management, and in particular to a store marketing television multi-terminal management system. Background Art

[0002] In some stores with larger areas, a large number of marketing TVs are usually set up to play store marketing advertisements, such as discounted products, discount activities and brand promotional videos. There are generally two ways to control the files played by the marketing TV. The first is the traditional control method, that is, through a removable storage device such as a USB flash drive, the pre-prepared files to be played are copied to the marketing TV, and the marketing TV plays them according to the pre-set strategy, such as loop playback. This method has low equipment cost; the second is to transmit the files to be played to the marketing TV through wireless communication, and then the marketing TV loops the files to be played according to the pre-set playback strategy, or sends the files to be played and the playback strategy to the marketing TV at the same time, and the marketing TV plays them according to the playback strategy.

[0003] The first method has the problems of inconvenience in changing the files to be played and a single playback strategy. Because marketing TVs are generally set at a higher position, each time the personnel who change the files to be played need to raise the TV before they can reach the marketing TV. Moreover, if there are multiple marketing TVs at the same time, it is necessary to repeatedly update the files played by each marketing TV in turn, which requires a large workload. Therefore, as the price of TVs becomes lower and lower, the configuration becomes higher and higher, and they are generally equipped with wireless communication devices such as WiFi, more and more marketing TVs use the second method to update the files to be played. When updating, you only need to select the marketing TV that needs to be updated in the store TV terminal management system, select the files to be updated, and the rest can be automatically completed by the store TV terminal management system.

[0004] However, the existing marketing TV terminal management system cannot automatically switch the type of files played according to the changes in the playback environment, so as to make the played files better adapt to the real-time environment and improve the playback effect. For example, in a noisy playback environment, if you still choose to play a video with sound, the customers around the marketing TV cannot hear the sound clearly, and it is also easy to affect the customer experience, because some customers will feel that the marketing TV makes the environment too noisy.

[0049] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the accompanying drawings required for describing the embodiments will be briefly introduced below. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other accompanying drawings can be obtained based on these accompanying drawings without paying creative work.

[0050] Figure 1 The present invention is a schematic diagram of a store marketing television multi-terminal management system.

[0051] Figure 2 It is a schematic diagram of the process of generating a control strategy based on a device number according to the present invention. DETAILED DESCRIPTION

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] The present invention provides a store marketing television multi-terminal management system, comprising a marketing television, a data collection device, a data analysis device and a terminal management device;

[0054] The data acquisition device is used to acquire the environmental sound of the environment in which the marketing television is located based on a set acquisition cycle, and transmit the environmental sound to the data analysis device;

[0055] The data analysis device is used to determine whether the volume of the ambient sound transmitted by each data acquisition device is greater than the set volume threshold, and send the device number of the data acquisition device corresponding to the ambient sound greater than the set volume threshold among all ambient sounds acquired at the same time to the terminal management device;

[0056] The terminal management device is used to generate a control strategy according to the device number and send the control strategy to each marketing TV that needs to be controlled;

[0057] Marketing TV is used to control the files played according to the control policy.

[0058] The above scheme is different from the control strategy of existing marketing televisions. Existing marketing televisions generally require managers to actively control the content being played, and cannot passively and adaptively change the type of files being played according to changes in the playback environment. When the ambient volume is too loud, the type of files being played cannot be switched in time, for example, from playing videos containing sound to playing pictures. In this way, active suppression of the ambient volume can be achieved, thereby improving the customer's consumption experience.

[0059] In the present invention, the marketing TV can be installed by hanging, or installed on a pillar or wall of the store. The data collection device can be set on the ceiling.

[0060] Specifically, the volume threshold may be set in the range of 75 decibels to 85 decibels. Preferably, the set volume threshold may be 80 decibels.

[0061] Preferably, the volume of the ambient sound is an average value of the volumes of all sampling points of the ambient sound.

[0062] Preferably, the data acquisition device includes a countdown module, a sound acquisition module and a communication module;

[0063] The countdown module is used to count down for a time length equal to the collection period after the previous environmental sound collection is completed, and send a collection signal to the sound collection module after the countdown ends;

[0064] The sound collection module is used to record the ambient sound for a preset time after receiving the collection signal;

[0065] The communication module is used to transmit the environmental sound obtained by the sound collection module to the data analysis device through wireless communication.

[0066] Specifically, the collection period may be a value in the range of 10 seconds to 60 seconds. Preferably, the collection period is 30 seconds.

[0067] Specifically, the preset duration is 5 seconds.

[0068] Specifically, the acquisition signal may be a level signal, a pulse signal, a digital signal, etc.

[0069] When the acquisition signal is a level signal, the countdown module triggers the recording action of the sound acquisition module by sending a high level (usually 3.3V or 5V) or a low level. The sound acquisition module starts recording after detecting this level change.

[0070] The communication module can transmit the environmental sound obtained by the sound collection module to the data analysis device through WiFi communication.

[0071] Preferably, all environmental sounds at the same time are obtained, including:

[0072] During the data collection process, the data collection device starts and ends collecting all environmental sounds at the same time.

[0073] In the present invention, the environmental sound is collected periodically, and different data collection devices are time-synchronized after installation, so that when the environmental sound is obtained in the same collection cycle, the time of starting and ending the collection is the same.

[0074] Preferably, the process of determining the installation position of the data acquisition device includes:

[0075] Get a marketing TV floor plan;

[0076] Divide the plane distribution map into a plurality of rectangular areas of preset sizes;

[0077] The installation position of the data acquisition device is obtained based on the center of the rectangular area.

[0078] Preferably, the rectangular area of ​​the preset size is a square area with a side length of Z meters, and the calculation formula of Z is as follows:

[0079] Z = L × mpl

[0080] L represents the diagonal length of the marketing TV, the unit of L is meter, mpl represents the distance multiple, mpl∈[5,10].

[0081] In the present invention, the size of the rectangular area is related to the length of the diagonal of the marketing TV. The larger the marketing TV is, the farther the viewing distance at which the content on the screen can be clearly seen, thereby making the influence range of the marketing TV larger. Accordingly, the present invention will also increase the size of the rectangular area to avoid the situation where the rectangular area is too small, resulting in an excessive number of rectangular areas, and the number of marketing TVs contained in the rectangular area is too small, resulting in the need to set up too many data acquisition devices.

[0082] Preferably, the value of mpl is 6.

[0083] Preferably, obtaining the installation position of the data acquisition device based on the center of the rectangular area includes:

[0084] Get the actual corresponding position of the center of the rectangular area in the store;

[0085] The position of the ceiling directly above the actual corresponding position is used as the installation position of the data acquisition device.

[0086] Preferably, the control strategy is generated according to the device number, including:

[0087] Calculate control coefficient based on equipment number;

[0088] Determine whether the control coefficient is greater than the set control coefficient comparison value. If so, generate a control strategy based on the device number.

[0089] In the present invention, the type of the file played by the marketing TV near the data collection device corresponding to the ambient sound greater than the set volume threshold is not directly changed, because in this way, when a short sudden noise occurs, the file played by the marketing TV will also be switched, resulting in a high switching frequency, which will also affect the customer's viewing experience. Therefore, the present invention calculates the control coefficient first, and then compares the size relationship between the control coefficient and the set control coefficient comparison value, so as to achieve a higher quality switching.

[0090] Preferably, the control coefficient is calculated based on the number of the equipment, including:

[0091] Use U h and U h+1 represents a set of data collection devices corresponding to the ambient sounds greater than the set volume threshold obtained based on the hth collection period and the h+1th collection period;

[0092]

[0093] ctrlcoef h+1 Indicates that based on U h+1 The control coefficient is calculated from the device number in the figure. ditmaxc represents the maximum distance between the two data acquisition devices. ditmid h,h+1 Respectively represent the data acquisition device maxmch h and maxmch h+1 The distance between h and maxmch h+1 The data acquisition devices respectively represent the data acquisition devices corresponding to the ambient sound with the loudest volume in the hth acquisition cycle and the h+1th acquisition cycle; shw represents the moving direction judgment coefficient; ctn h+1 It represents the total number of empty sets contained in the N sets of data acquisition devices corresponding to the ambient sounds greater than the set volume threshold obtained in the most recent N acquisition cycles, and λ1, λ2 and λ3 represent the weighting coefficients of distance, direction and quantity respectively.

[0094] The control coefficient of the present invention is weighted from the parameters of three directions, so that the influence of sudden noise interference on the control strategy can be more effectively reduced, and the type of files played by the marketing TV can be avoided from being changed too frequently. When the distance between the locations of the appearance of the ambient sound with the largest volume in two adjacent acquisition cycles is smaller, the duration of the ambient sound greater than the set volume threshold is longer, and the direction judgment coefficient is larger, it means that the probability of the ambient sound greater than the set volume threshold moving in the store is greater. At this time, the control coefficient is smaller, so that the control coefficient can be calculated by combining the ambient sounds obtained by multiple data acquisition devices and the moving direction and probability of the largest ambient sound, so that the calculated control coefficient can more accurately reduce the probability of the type of files played by the marketing TV being switched when sudden noise occurs.

[0095] Preferably, the value of N is 5.

[0096] Preferably, the value of h is greater than or equal to 5. At the beginning of operation, since the collection cycle is less than 5, when processing the ambient sound obtained in the first 5 collection cycles, the control coefficient is fixed to a value less than or equal to the set control coefficient comparison value.

[0097] Preferably, the weighting coefficients of distance, direction and quantity are all

[0098] Preferably, the control coefficient comparison value is set to 0.6.

[0099] Preferably, the process of obtaining the moving direction determination coefficient includes:

[0100] Obtain a store floor plan with the locations of data collection devices marked;

[0101] In the store floor plan, maxmch h The location is the endpoint, make a maxmch h+1 Ray rdl h+1 ;

[0102] In the store plan, obtain the coordinates (xa, ya) of the store entrance, where xa and ya are the horizontal and vertical coordinates of the center of the store's door, respectively;

[0103] Calculate the moving direction judgment coefficient:

[0104]

[0105] ditrdlma represents the line segment Line h+1 The maximum distance between (xa,ya); Line h+1 For rdl h+1The straight line segment between the endpoint and (xb, yb), (xb, yb) is rdl h+1 In the store plan, the edge of the store area is consistent with the rdl h+1 The coordinates of the intersection point, ditrdld represents the distance between (xa,ya) and (xb,yb).

[0106] The moving direction judgment coefficient of the present invention is mainly calculated by calculating the positional relationship between the moving direction of the position of the maximum volume obtained in two adjacent collection cycles and the entrance of the store. The smaller the distance between the intersection of the extension line of the moving direction and the edge of the store area and the entrance, the smaller the direction judgment coefficient is. At this time, the greater the probability that the customer's moving route is a moving route leaving the store. Therefore, in the calculation parameters of the control coefficient, when the other two parameters remain unchanged or become smaller, the control coefficient becomes smaller accordingly, which can more accurately reduce the probability of switching the type of file played by the marketing TV.

[0107] Preferably, if Figure 2 As shown, the control strategy is generated based on the device number, including:

[0108] The first step is to determine the data acquisition device corresponding to each device number;

[0109] The second step is to obtain all marketing televisions within the influence range of each data collection device determined in the first step;

[0110] Step 3: Store all the marketing TV programs obtained in step 2 into set F;

[0111] Step 4, respectively obtain the type of the file currently played by each marketing TV in set F;

[0112] The fifth step is to determine the control strategy for each marketing TV in set F according to the type obtained in the fourth step.

[0113] Preferably, all marketing televisions within the influence range of the data collection device include all marketing televisions whose distances from the data collection device are less than Z.

[0114] Preferably, the types of files include images and videos.

[0115] Since images do not contain sound information, they are more suitable for playing in noisy environments than videos. When the noise in the environment is low, videos with sound can be played to provide customers with a better viewing experience. At the same time, sound can also better attract customers to watch marketing TV.

[0116] Preferably, the control strategy of each marketing television in the set F is determined separately, including:

[0117] For a marketing TV t in set F, if the type of the file currently played by t is video, the control strategy is: change the type of the file currently played by t to image;

[0118] If the type of the file currently played by t is an image, the control strategy is: do not change the type of the file played by t.

[0119] Preferably, the data analysis device is further used to send a set Z of device numbers of data acquisition devices corresponding to ambient sounds with a volume lower than a set threshold value among all ambient sounds acquired at the same time to the terminal management device.

[0120] Preferably, the terminal management device is further used to obtain the control scheme of each marketing television respectively, including:

[0121] Perform the following processing on each device number in Z:

[0122] Get marketing TVs that are within the reach of the device number;

[0123] Determine whether the type of the file currently played by the marketing TV is video. If so, the control solution is not to change the type of the file played by the marketing TV; if not, the control solution is to change the type of the file currently played by the marketing TV to video.

[0124] The above process mainly controls the type of file played by the marketing TV to switch to playing a video containing sound when the ambient volume becomes smaller, so as to achieve better advertising effect.

[0125] Preferably, the terminal management device is also used to send the control solution to the corresponding marketing television.

[0126] Preferably, the marketing television comprises an image acquisition module, an image recognition module and a playback control module;

[0127] The image acquisition module is used to periodically acquire the image in front of the marketing TV according to the set tilt angle;

[0128] The image recognition module is used to recognize the image obtained by the image acquisition module and obtain the control gesture in the image obtained by the image acquisition module;

[0129] The playback control module is also used to switch the files played by the marketing TV based on control gestures.

[0130] In addition to passively switching the files to be played on the marketing TV, the present invention also allows customers to actively switch the files to be played, thereby improving the interactivity of the marketing TV, thereby better attracting customers' attention to the content in the marketing TV while they are waiting.

[0131] Preferably, the image acquisition module is arranged around the marketing TV and takes pictures tilted downward. The periodic acquisition may be performed every 1 second.

[0132] Preferably, the set inclination angle is 20 degrees.

[0133] Preferably, recognizing the image obtained by the image acquisition module and acquiring the control gesture in the image obtained by the image acquisition module includes:

[0134] For the image p obtained by the image acquisition module in the mth cycle m , the process of identifying it is as follows:

[0135] S1, obtain the image p obtained in the image acquisition module in the m-1th cycle m-1 ;

[0136] S2, get p m Relative to p m-1 For example, the set of pixels that have changed is pxu;

[0137] S3, calculate cutting height h based on pxu m ;

[0138] S4, p m In the figure, the h number from top to bottom m Delete the line and get the image cp m ;

[0139] S5, for cp m Identify and obtain cp m Control gestures in .

[0140] Since there are no pixels related to gestures in the upper part of the image, if this part is also used as the target of image recognition, it will result in too many pixels to be recognized, which will affect the recognition speed. However, it is not appropriate to set a fixed value, because customers have different heights, which will cause the heights of gestures to appear to be different. Therefore, the present invention calculates the cutting height based on pxu, so that the cutting height can be better matched with the actual customer height, the degree of crowding in the store, etc., which is conducive to obtaining a more accurate cutting height, so that while effectively retaining a part of the image containing the gesture, the probability of the part of the image that is abandoned for recognition containing information related to the gesture is reduced, and a more accurate adaptive deletion result is obtained.

[0141] Preferably, obtaining p m Relative to p m-1 For example, the set of changed pixels pxu includes:

[0142] Get p respectively m and p m-1 The corresponding grayscale image gp m and gp m-1 ;

[0143] Get gp separately m and gp m-1 The pixel points pixa and pixb with coordinates (x, y) in;

[0144] Calculate the absolute value of the difference between the grayscale values ​​of pixa and pixb;

[0145] Determine whether the absolute value is greater than the set absolute value threshold. If so, store pixa in the set pxu.

[0146] Preferably, the absolute value threshold is set to 10.

[0147] Preferably, the cutting height h is calculated based on pxu m ,include:

[0148] h m The calculation formula is as follows:

[0149]

[0150] alrow represents the number of rows in the image, toprow represents the maximum number of rows where the pixels in pxu are located when the rows in the image are numbered from bottom to top, Nbast represents the set number of comparison values, and Num represents the comparison of gp m-1 gp obtained by identification m-1 The number of customers included in ; α represents the height weight, and β represents the customer quantity weight.

[0151] The cutting height of the present invention is based on the change of the height of the pixel points in pxu and gp m-1 The number of people in the game is determined comprehensively. The lower the height of the pixel in pxu, the higher the gp m-1 When the number of people in is smaller, h m The larger the value of gp, the greater the probability that the gesture appears at a lower height; the higher the height of the pixel in pxu, the higher the probability that the gesture appears at a lower height. m-1 The more people there are, the greater the m The smaller the value of , the greater the probability that the gesture appears at a higher height, thereby achieving accurate adaptive changes in the cutting height.

[0152] Preferably, the height weight and customer quantity weight are and
