[0049] In the following, only some exemplary embodiments are simply described. As can be realized by those skilled in the art, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than limiting.

[0050] First, several terms related to the embodiments of the present application are introduced:

[0051] Self-service vending device: a device that can be used by a user to purchase goods, which can integrate a display device and a smart terminal.

[0052] Message queue: can be used to solve application coupling, asynchronous message, traffic clipping, etc., to realize high-performance, high-availability, scalable and eventually consistent architecture middleware.

[0053] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems are described in detail in the following specific embodiments.

[0054] An information pushing method provided by an embodiment of the present application can be applied to a terminal device, such as a smart refrigerator, a self-service vending device, etc. Figure 1 As shown in the figure, the method comprises:

[0055] S101, detecting whether a user enters a first area near the terminal device.

[0056] The terminal device can be any one of a smart refrigerator, a self-service vending device, etc.

[0057] The range of the first area can be set according to actual needs, which is not limited by the embodiments of the present application.

[0058] S102, acquiring facial feature information of the user in a case where it is determined that the user enters the first area.

[0059] In a case where it is determined that no user enters the first area, the detection in S101 can be continuously performed.

[0060] In S103, the facial feature information is sent to the server.

[0061] In S104, multimedia information fed back by the server for the facial feature information is acquired and pushed.

[0062] The multimedia information can be at least one of an advertisement (at least one of an audio advertisement, a video advertisement, a picture advertisement, etc.), a video of a movie or a TV series, a short video, and the like, and can also be other types of multimedia information that can be pushed, which is not limited in the embodiments of the present application.

[0063] The information pushing method provided by the embodiments of the present application can realize pushing of multimedia information on a terminal device through information interaction between the terminal device and the server, and can push multimedia information matched with a user based on facial feature information of the user in a case where the user approaches the terminal device, so as to realize accurate pushing for the user.

[0064] In the above step S101, whether a user enters the first area can be detected by a detection device in the terminal device. The detection device can be an infrared sensor.

[0065] In the above step S102, the facial feature information of the user can include: acquiring a facial image of the user collected by a camera in the terminal device, and identifying the facial image to obtain the facial feature information. The identification of the facial image can be realized by a pre-trained image recognition model, which can be a neural network model.

[0066] Optionally, when the facial image is identified, the facial shape feature, the gender feature and the age feature of the facial image can be identified to obtain high-quality facial feature information including facial shape feature parameters, gender feature parameters and age feature parameters, which is beneficial to subsequent accurate comparison with the facial feature information of the server.

[0067] In an optional embodiment, the information pushing method applied to the terminal device provided by the embodiments of the present application can further include:

[0068] The multimedia information provided by the server for a geographical range to which the terminal device belongs (referred to as first multimedia information) is acquired, and the first multimedia information is pushed before the multimedia information fed back by the server for the facial feature information (referred to as second multimedia information) is acquired. In a case where the second multimedia information is acquired, the pushing content can be switched from the first multimedia information to the second multimedia information.

[0069] The first multimedia information can include multimedia material information to be pushed and an information list of the multimedia material information, and the information list can be made by the server based on the multimedia material information.

[0070] Based on this manner, the terminal device of the embodiment of the present application can push the default first multimedia information when there is no user nearby, and can acquire and accurately push the second multimedia information for the user when the user is nearby, so as to realize the diversity of information pushing in different stages.

[0071] The information pushing method applied to the terminal device provided by the embodiment of the present application can further detect whether a user enters a third area, and the operation of acquiring the first multimedia information can be executed under the condition that the user enters the third area, and the distance between the third area and the terminal device can be greater than the distance between the first area and the terminal device.

[0072] Based on this manner, while realizing the diversity of information pushing, the default first multimedia information can be further pushed when the user enters the third area, that is, there is user activity near the terminal device, so as to reduce the pushing time of the default first multimedia information, reduce invalid pushing when there is no user activity near the terminal device, and reduce power consumption.

[0073] In an optional embodiment, as shown in Figure 2 The information pushing method applied to the terminal device provided by the embodiment of the present application can further include the following steps S201-S203:

[0074] S201, the terminal device detects whether a user enters a second area; if yes, S202 is executed, and if no, S203 is executed.

[0075] The distance between the second area and the terminal device is less than the distance between the first area and the terminal device. That is, compared with the first area, the second area is an area closer to the terminal device.

[0076] S202, the pushing strength of the multimedia information is reduced, or the pushing of the multimedia information is stopped.

[0077] When the user enters the second area closer to the terminal device, the user can perform some operations on the terminal device, for example, for a smart refrigerator and a self-service vending device, the user can open the door of the smart refrigerator and the self-service vending device to check or take out the goods. In order to avoid the interference of the pushed content on the user, the pushing can be stopped.

[0078] Reducing the pushing strength of the multimedia information can include reducing the display brightness of a transparent display device in the terminal device.

[0079] Stopping the pushing of the multimedia information can include turning off the display function of the transparent display device in the terminal device.

[0080] The transparent display device is a device that can display information and has certain penetration. When the display function is turned on, information can be displayed. When the display function of the transparent display device is turned off, the user can see the background on the other side through the transparent display device. For a smart refrigerator and a self-service vending device, the display brightness of the transparent display device arranged on the cabinet door can be reduced or the transparent display device arranged on the cabinet door can be turned off, so that the user can see the articles in the smart refrigerator and the self-service vending device through the transparent display device.

[0081] S203, the terminal device keeps the current state.

[0082] The current state can be to push the default first multimedia information or not to push any information.

[0083] In the step S202, the specific manner of reducing the push strength of the multimedia information can be adjusting the push strength of the multimedia information according to the change of the distance between the user and the terminal device. When the distance between the user and the terminal device becomes smaller, the push strength of the multimedia information is reduced. With the continuous reduction of the distance between the user and the terminal device, the push strength of the multimedia information can be continuously reduced.

[0084] The push strength can be represented by the display brightness of the display device. The adjustment of the push strength can be realized by adjusting the display brightness of the multimedia information on the display device. For example, in the process of continuously approaching the terminal device, the display brightness of the transparent display device can be continuously reduced. When the distance between the user and the terminal device is reduced to a certain set distance, the display brightness is reduced to a lower brightness value and maintained at the display brightness, or the display brightness is reduced to the display function of the display device is turned off.

[0085] Optionally, the information push method provided by the embodiment of the application can further include detecting whether the user leaves the second area. When it is determined that the user leaves the second area, the push content can be converted from the second multimedia information matched with the user to the default first multimedia information.

[0086] In an optional embodiment, the terminal device can be a self-service vending device, such as a refrigerator. Figure 3 As shown in the figure, the information push method applied to the terminal device provided by the embodiment of the application can further include the following steps S301-S302:

[0087] S301, in response to a consumption start signal triggered by the user, the feature of the goods taken out by the user is recognized through a goods recognition algorithm to obtain the goods feature information of the taken-out goods.

[0088] The user can trigger the consumption start signal in any of the following ways: inputting information such as the type and quantity of the goods to be purchased through an input device, or opening the door of the self-service vending device.

[0089] The goods recognition algorithm can be provided by the server, and the self-service vending device can store the goods recognition algorithm for subsequent goods recognition.

[0090] S302, in response to the consumption end signal triggered by the user, sending the goods feature information of the taken goods to the server.

[0091] The user can trigger the consumption end signal in any of the following ways: completing payment for the purchased goods, or closing the door of the self-service vending device.

[0092] Through steps S301-S302, the server can record the user's consumption behavior in a timely manner, effectively associate the goods and the user, and facilitate analysis of the user's consumption behavior and habits.

[0093] The server can initiate payment to the user before or after receiving the goods feature information uploaded by the self-service vending device, for example, through the display device of the terminal device or the mobile device of the user.

[0094] In the embodiments of the present application, the terminal device can send the face feature information, consumption information, and goods feature information to the server through a message queue.

[0095] In the embodiments of the present application, the goods recognition algorithm can be configured by the server and sent to the terminal device.

[0096] In the embodiments of the present application, the specific way in which the terminal device pushes the multimedia information (for example, the first multimedia information or the second multimedia information) can include: displaying the multimedia information through a display device provided on the terminal device.

[0097] Based on the same inventive concept, the embodiments of the present application also provide an information pushing method, which can be applied to a server, as shown in the method includes: Figure 4

[0098] S401, obtaining the face feature information of the user provided by the terminal device.

[0099] The face feature information is detected by the terminal device when the user enters a first area near the terminal device.

[0100] S402, querying the multimedia information matched with the user according to the face feature information.

[0101] ​S403, send the multimedia information to the terminal device.

[0102] Based on the information pushing method, the server can query the multimedia information matched with the user according to the facial feature information of the user and feed back the terminal device, so that the terminal device can push the multimedia information accurately.

[0103] In the step S402, as shown in the following steps S501-S504, Figure 5

[0104] S501, determine whether the facial feature information provided by the terminal device is stored; if yes, execute S502, if not, execute S504.

[0105] The server can pre-store the facial feature information of multiple users, and when receiving the facial feature information of the current user, query whether the facial feature information of the current user exists in the pre-stored multiple facial feature information. If it exists, it means that the information of the user has been recorded, if it does not exist, it means that the information of the user has not been recorded.

[0106] In one example, the server can pre-store the facial feature information of users A, B and C, and when receiving the current facial feature information, query whether the facial feature information of the current user exists in the facial feature information of users A, B and C. For example, if the similarity of the facial feature information of the current user and the facial feature information of user A is greater than a preset similarity threshold, it can be considered that the facial feature information of the user and the facial feature information of the current user are the facial feature information of the same user, and the user and the current user are the same user, that is, the facial feature information of the current user has been stored.

[0107] S502, query the consumption preference information associated with the facial feature information provided by the terminal device.

[0108] The server can pre-store the historical consumption information of multiple users, statistically analyze the historical consumption information of each user to obtain the consumption preference information reflecting the consumption preference of each user, and establish the association relationship between the consumption preference information and the facial feature information for each user.

[0109] In the case that the facial feature information of the current user is received and confirmed to have been stored, the consumption preference information associated with the facial feature information of the current user can be queried in the pre-stored association relationship between the consumption preference information and the facial feature information.

[0110] ​In one example, the server can pre-store the historical consumption information of users A, B and C, respectively analyze the historical consumption information of the three users, obtain the corresponding consumption preference information, and respectively establish the association between the consumption preference information and the facial feature information of the three users. In the case that the facial feature information of the current user is received and it is confirmed that the current user is user A based on the facial feature information, the consumption preference information of user A can be determined as the consumption preference information associated with the facial feature information of the current user based on the association between the consumption preference information of user A and the facial feature information of user A.

[0111] S503, obtaining multimedia information meeting the consumption preference of the user as the multimedia information matched with the user according to the queried consumption preference information.

[0112] In one example, the server can pre-acquire a plurality of candidate multimedia information from the device of the multimedia information provider and store them, and after determining the consumption preference information associated with the facial feature information of the current user, the multimedia information meeting the consumption preference of the user can be obtained from the stored candidate multimedia information as the multimedia information matched with the user.

[0113] In another example, the server can obtain the multimedia information meeting the consumption preference of the user from the device of the multimedia information provider in real time after querying the consumption preference information.

[0114] S504, storing the facial feature information provided by the terminal device.

[0115] When a new user is encountered, the new facial feature information is stored, which can expand the data amount of the facial feature information in the server as the data basis for querying the facial feature information, consumption preference information, multimedia information and the like next time.

[0116] Through the above steps S501-S504, the server of the embodiment of the application can query the consumption preference information of the user based on the facial feature information of the user, and further obtain the multimedia information based on the consumption preference information of the user, which can make the screened multimedia information meet the consumption preference of the user and improve the pushing effect of the multimedia information.

[0117] In an optional implementation, in the case that the terminal device is a self-service vending device, as shown in FIG. 6, the information pushing method applied to the server provided by the embodiment of the application can further include the following steps S601-S602: Figure 6

[0118] S601, obtaining the historical consumption information of the user provided by the self-service vending device.

[0119] The historical consumption information can include the product feature information recognized in the multiple consumption processes, and can also include the consumption times.​

[0120] The historical consumption information can be sent to the server in multiple times, i.e., the consumption information of each consumption is sent to the server as part of the historical consumption information in response to a consumption end signal after each consumption ends, or the historical consumption information is locally stored and sent to the server in whole or in part upon a request of the server.

[0121] S602, statistical analysis is performed on the historical consumption information of the user to obtain at least one of consumption preference information and consumption trend information of the user.

[0122] The consumption preference information of the user can include a type of goods which is purchased most frequently or in the largest quantity by the user in a set time period. The set time period can be a relatively recent time period before the current time, such as a week, a month, etc., which can be set according to actual needs. The type of goods can include types such as carbonated drinks, fruit juice, etc., or specific brand types.

[0123] The consumption trend information of the user can include a change feature of the consumption preference of the user in different time periods. The different time periods for comparison of the consumption preference can be set according to specific needs, such as a comparison between two months, e.g., May and June, before the current time, in which the user purchases carbonated drinks most frequently in May and purchases fruit juice most frequently in June, and the consumption preference of the user changes from carbonated drinks to fruit juice.

[0124] The consumption preference information of the user can serve as a data basis for feedback of multimedia information to the terminal device to achieve accurate pushing.

[0125] The consumption preference information and the consumption trend information of the user can serve as a data basis for relevant decisions of a multimedia information provider, such as an advertiser, and be provided to the multimedia information provider, which can determine what kind of multimedia information needs to be provided to the self-service vending device according to the data basis. For example, if the consumption preference of the user is carbonated drinks or the consumption preference changes to carbonated drinks, the multimedia information provider can provide more information of carbonated drinks to the server for targeted feedback to the self-service vending device.

[0126] The consumption preference information and the consumption trend information of the user can also serve as a data basis for relevant decisions of an operator of the self-service vending device, such as the operator of the self-service vending device can determine what kind of goods needs to be configured for the self-service vending device and how many goods need to be configured according to the data basis. For example, if the consumption preference of the user is carbonated drinks or the consumption preference changes to carbonated drinks, the operator of the self-service vending device can replenish more carbonated drinks in the self-service vending device to meet the purchase needs of the user.

[0127] In the embodiment, the historical consumption information of the user can be obtained from one self-service vending device or from multiple self-service vending devices.

[0128] In another optional embodiment, in the case that the terminal device is a self-service vending device, as shown in the figure, the information pushing method applied to the terminal device provided by the embodiment of the application can further include the following steps S701-S702: Figure 7

[0129] S701, obtaining the historical consumption information of different types of users provided by the self-service vending device.

[0130] The different types of users can include any of the following cases: users in different geographical ranges, users of different genders, users in different age groups, etc. One geographical range can be a street, a business district, a specific commercial site (such as a shopping mall or an office building), etc.

[0131] The historical consumption information of the different types of users can include the product feature information identified in the multiple consumption processes of each type of user, and can also include the number of consumptions.

[0132] S702, statistically analyzing the historical consumption information of the different types of users to obtain the consumption preference information of each type of user.

[0133] The consumption preference information of the different types of users can include the product type with the most number of purchases or the largest purchase amount of each type of user in a set time period. The set time period can be a relatively recent time period before the current time, such as a week, a month, etc., which can be set according to actual needs. The product type can include carbonated beverages, fruit juice, etc., or can include specific brand types.

[0134] In one example, the historical consumption information of users in different business districts can be statistically analyzed. If the product type with the most number of purchases or the largest purchase amount of users in business district one in a set time period is carbonated beverages, and the product type with the most number of purchases or the largest purchase amount of users in business district two in the same time period is fruit juice, then the consumption preference of the users in business district one is carbonated beverages, and the consumption preference of the users in business district two is fruit juice.

[0135] In another example, the historical consumption information of users in different age groups can be statistically analyzed. If the product type with the most number of purchases or the largest purchase amount of elderly users in a set time period is tea, and the product type with the most number of purchases or the largest purchase amount of young users in the same time period is carbonated beverages, then the consumption preference of the elderly users is tea, and the consumption preference of the young users is carbonated beverages.

[0136] ​The consumption preference information of different types of users can serve as a data basis for relevant decision-making of a multimedia information provider (e.g., an advertiser), and the multimedia information provider can determine what kind of multimedia information needs to be provided to the self-service vending device based on the data basis.

[0137] For example, if the consumption preference of users in a first commercial area is carbonated beverages and the consumption preference of users in a second commercial area is juice, the multimedia information provider can provide the server with information of carbonated beverages and juice, and the server can provide the self-service vending device in the first commercial area with multimedia information of carbonated beverages and the self-service vending device in the second commercial area with multimedia information of juice. For another example, if the consumption preference of elderly users is tea and the consumption preference of young users is carbonated beverages, the multimedia information provider can provide the server with multimedia information related to tea and carbonated beverages to meet the purchase demand of users of different ages.

[0138] The consumption preference information of different types of users can also serve as a data basis for relevant decision-making of a self-service vending device operator, and the self-service vending device operator can determine what kind of goods need to be configured for the self-service vending device and how many goods need to be configured based on the data basis.

[0139] For example, if the consumption preference of users in a first commercial area is carbonated beverages and the consumption preference of users in a second commercial area is juice, the self-service vending device operator can replenish the self-service vending device in the first commercial area with carbonated beverages and replenish the self-service vending device in the second commercial area with juice to meet the purchase demand of users in different commercial areas. For another example, if the consumption preference of elderly users is tea and the consumption preference of young users is carbonated beverages, the self-service vending device operator can replenish the self-service vending device with tea and carbonated beverages to meet the purchase demand of users of different ages.

[0140] For different gender users or users of different ages, after the consumption preference information of users of each gender or the consumption preference information of users of each age is analyzed, the consumption preference information of users of each gender can be compared, or the consumption preference information of users of each age can be compared, to determine a type of goods with a higher purchase frequency or purchase quantity, and multimedia information or replenishment of the type of goods can be provided.

[0141] In the embodiment, when the different types of users are different gender users or users of different ages, the historical consumption information of the different gender users or the users of different ages can be sourced from one self-service vending device or multiple self-service vending devices; when the different types of users are users in different geographical ranges, the historical consumption information of the users in different geographical ranges is sourced from self-service vending devices in the different geographical ranges, and the historical consumption information of users in the same geographical range can be sourced from one or more self-service vending devices in the geographical range.

[0142] The consumption preference information and the consumption trend information in the embodiments of the present application can be visualized information, so as to be visually displayed to the multimedia information provider and the operator of the self-service vending device.

[0143] In an optional embodiment, in the case that the terminal device is a self-service vending device, the information pushing method provided by the embodiments of the present application further comprises:

[0144] The server acquires first time information of historical pushing operations (i.e. operations of pushing historical multimedia information) provided by the self-service vending device and second time information of historical consumption behaviors of the user; and determines whether there is a time-associated historical pushing operation and a historical consumption behavior according to the first time information and the second time information, so as to determine a hit rate of the historical pushing multimedia information.

[0145] The hit rate of the historical pushing multimedia information represents a proportion of a number of the time-associated historical pushing operations to a total number of historical pushing operations.

[0146] The time association includes any one of the following cases: a time range in which the historical consumption behavior occurs overlaps with a time range of the historical pushing operation; or, the time range in which the historical consumption behavior occurs does not overlap with the time range of the historical pushing operation, but a difference between a starting time of the historical consumption behavior and an ending time of the time range of the historical pushing operation is less than a set threshold.
