[0076] The preferred embodiments of the present application will be described hereinafter with reference to the accompanying drawings, in which, it should be understood that the preferred embodiments described herein are intended for explaining and illustrating the present application, and are not intended for limiting the present application.

[0077] The embodiment of the present application provides a weighing vending machine with a continuous weighing system, as shown in Fig. 1, which comprises a machine body 6, a plurality of product placing frames 1 arranged in the machine body 6, a weighing module 2 arranged under each product placing frame 1, a first image acquisition module 3 arranged above the machine body 6, a second image acquisition module 4 arranged in the machine body 6 and corresponding to each product placing frame 1, and a processing module 5 arranged in the machine body 6. Figs. 1 to 3 The processing module 5 performs the following operations:

[0078] The processing module 5 performs the following operations:

[0079] When the door of the machine body 6 is opened, a first image in front of the machine body 6 is acquired by the first image acquisition module 3.

[0080] When the door of the machine body 6 is opened, a second image of each product placing frame 1 is acquired by the second image acquisition module 4.

[0081] Based on the first image and / or the second image, a weighing time is determined.

[0082] At the determined weighing time, weighing information is acquired by the weighing module 2.

[0083] When the door of the machine body 6 is closed, settlement information is generated based on the weighing information.

[0084] The processing module 5 determines the weighing time based on the first image and / or the second image, and performs the following operations:

[0085] A human hand region in the first image is extracted, and a first region image is acquired.

[0086] A product is identified based on the first region image, and when the product is identified, the current time is determined as the weighing time.

[0087] A human hand region in the second image is extracted, and a second region image is acquired.

[0088] A third region image of the product placing frame 1 corresponding to the second image acquisition module 4 corresponding to the second image in the second image is extracted.

[0089] extracting a human arm region in the second image to obtain a fourth region image;

[0090] determining whether the second region image and the third region image overlap and whether the third region image and the fourth region image overlap;

[0091] when none of them overlap, performing product recognition on the second region image, and when a product is recognized, determining that this is the weighing opportunity;

[0092] when the second region image and the third region image do not overlap, and the third region image and the fourth region image have an overlapping region;

[0093] constructing an identification coordinate system, determining a first coordinate parameter of the center of the third region image, a second coordinate parameter of the center of the second region image, a third coordinate parameter of the center of the fourth region image, and a fourth coordinate parameter of the center point of the intersection of the second region image and the fourth region image;

[0094] based on the first coordinate parameter, the second coordinate parameter, the third coordinate parameter, and the fourth coordinate parameter, constructing a set of opportunity judgment parameters;

[0095] matching the set of opportunity judgment parameters with a set of standard parameters in a preset opportunity judgment library;

[0096] when the judgment result parameter corresponding to the set of standard parameters matching the set of opportunity judgment parameters in the opportunity judgment library is a preset first value, determining that this is the weighing opportunity. When the third region image and the fourth region image overlap, the user's arm may touch the product frame 1, and at this time, the weighing may be deviated due to the contact between the arm and the product frame 1. Therefore, by constructing the set of opportunity judgment parameters and then judging through the preset opportunity judgment library, the abnormal weighing after determining the weighing opportunity in the case where the arm touches the product frame 1 is avoided. When constructing the set of opportunity judgment parameters, the first coordinate parameter of the center of the third region image can identify the position of the product frame 1. The second coordinate parameter of the center of the second region image, the third coordinate parameter of the center of the fourth region image, and the fourth coordinate parameter of the center point of the intersection of the second region image and the fourth region image identify the positions of the human hand, wrist, and arm, so that the position of the human arm and the product frame 1 can be judged. However, the preset opportunity judgment library simplifies the position judgment step and directly determines whether it is the weighing opportunity. When constructing the opportunity judgment library, multiple experiments are mainly performed, the set of opportunity judgment parameters is constructed through experimental data, and then professional personnel perform image analysis to determine whether the corresponding image corresponds to the case where the arm touches the product frame 1. When it is, the associated judgment result parameter is set to a second value, otherwise, it is set to a first value. The first value can be set to 1, and the second value is set to 2;

[0097] When the door of the machine body 6 is closed, the processing module 5 generates settlement information based on the weighing information, and performs the following operations:

[0098] Based on the weighing information corresponding to the adjacent two times of weighing opportunities and the preset event determination library, event information is determined; the event information includes: taking information and placing article information;

[0099] Based on the event information, a taking list and a placing list of articles of the user are determined;

[0100] The taking list and the placing list of articles are compared to determine whether there is an article in the placing list of articles and not in the taking list;

[0101] When there is not, the article taken by the user and the article information corresponding to the article are determined based on the taking list and the placing list of articles;

[0102] Based on the article taken by the user and the article information and the preset price information of the corresponding article, settlement information is generated;

[0103] When there is, the article in the placing list of articles and not in the taking list is taken as a to-be-judged return article, and the taking list in the historical record in a preset time range before the current time is obtained;

[0104] Based on the article in the taking list in the historical record and the article information, it is determined whether the to-be-judged return article is a return article;

[0105] When it is not, prompt information is generated and played through the second reminding module;

[0106] When it is, based on the article taken by the user and the article information and the preset price information of the corresponding article, the return article and the settlement price corresponding to the return article, settlement information is generated.

[0111] In one embodiment, the weighing vending machine with a continuous weighing system further comprises:

[0112] A two-dimensional code attached to the door of the machine body 6;

[0113] When the two-dimensional code is scanned by the user's mobile terminal, the mobile terminal establishes a communication connection with the server and performs authorization verification; when the verification is passed, the server communicates with the processing module 5 through the communication module arranged in the machine body 6 and sends an opening instruction.

[0114] The use steps of the weighing vending machine are as follows: the user scans the two-dimensional code attached to the door through the mobile terminal, and based on the two-dimensional code, the mobile terminal establishes a communication connection with the server managing the weighing vending machine and performs authorization verification, mainly authorization of third-party payment settlement and acquisition of user information; the acquired user information includes user name, contact information, etc.; after the authorization verification is completed, the user can open the door of the machine body 6 to take the goods; when the door is closed after taking the goods, the processing module 5 performs settlement according to the taking situation.

[0115] In one embodiment, the weighing vending machine with a continuous weighing system further comprises:

[0116] A plurality of first reminder modules are arranged one by one on the outer periphery of the storage frame 1 and are electrically connected to the processing module 5; the first reminder module includes an LED light strip, and the LED light strip is wound around the outer periphery of the storage frame 1;

[0122] After the door of the machine body 6 is closed, obtain a third image of each storage frame 1 through the second image acquisition module 4;

[0123] Based on the third image, the commodity situation in each shelf 1 is determined; the commodity situation includes: the type, name and quantity of the commodity, etc.; the identification of the commodity is mainly through extracting the contour image of each commodity in the shelf 1 and matching the standard contour image in the preset commodity identification library to identify the type of the commodity; in addition, the existing mature technology will not be described here;

[0124] Based on the discount table, the discount situation of each commodity in each shelf 1 is determined;

[0125] Based on the commodity situation and the discount situation, the working mode of the first reminding module corresponding to the shelf 1 is determined;

[0126] Based on the determined working mode, the action of the first reminding module is controlled.

[0127] Among them, the processing module 5 determines the working mode of the first reminding module corresponding to the shelf 1 based on the commodity situation and the discount situation, and performs the following operations:

[0128] Based on the commodity situation, the shelf 1 is divided into a first group and a second group; the commodities in the shelf 1 in the first group are the same type, and there are multiple types of commodities in the second group; therefore, the second group is a mixed loading situation;

[0129] For the first group, when the discount situation of the commodity in the shelf 1 all belongs to the preset first discount range, the first reminding module corresponding to the shelf 1 is controlled to remind in the preset first reminding mode; when the discount situation of the commodity in the shelf 1 all belongs to the preset second discount range, the first reminding module corresponding to the shelf 1 is controlled to remind in the preset second reminding mode; when the commodity in the shelf 1 has no discount, the first reminding module is not controlled to work; wherein the discount intensity of the discount in the second discount range is greater than the discount intensity of the discount in the first discount range; for example: the first discount range is 80% to 95%, and the second discount range is 50% to 75%;

[0130] For the second group, the quantity proportion of each commodity whose discount situation is in the first discount range, the second discount range and no discount is determined; based on the quantity proportion, the working time of the first reminding mode, the second reminding mode and the non-working mode is determined; based on the determined working time, the first reminding module is controlled in the mode of alternately using the first reminding mode, the second reminding mode and the non-working mode.

[0131] The working principle and beneficial effects of the above technical solutions are:

[0132] Through the first reminding module, the user can intuitively see which goods in the weighing vending machine exist discounts, and the user can conveniently select and purchase discounted goods; in addition, different working modes of the first reminding module represent different discount intensities; wherein, the first reminding mode is yellow light display; the second reminding mode is green light display. In addition, the working time of the first reminding mode, the second reminding mode and non-working is determined based on the quantity proportion; the first reminding mode, the second reminding mode and non-working are alternately controlled based on the determined working time; specific examples can be used for illustration, for example: the quantity proportion corresponding to the first discount range is 50%, the quantity proportion corresponding to the second discount range is 30%, and the quantity proportion corresponding to no discount is 20%; the time of the corresponding first reminding mode is 10 seconds, the time of the second reminding mode is 6 seconds, and the time of non-working is 4 seconds; the specific LED light display is yellow light display for 10 seconds, then switching to green light display for 6 seconds, and finally closing for 4 seconds, then opening the yellow light display for 10 seconds, and so on.

[0133] In one embodiment, the weighing vending machine with a continuous weighing system further comprises:

[0134] A second reminding module is arranged in the machine body 6 and electrically connected with the processing module 5; the second reminding module comprises a loudspeaker;

[0135] The processing module 5 further performs the following operations:

[0136] When the door of the machine body 6 is opened, the second image is subjected to contour recognition, and each product contour is extracted;

[0137] The size of each product contour is tracked to determine the size change of each product contour; that is, the area of the product contour in the continuously photographed second image is calculated, and then the area is arranged according to the time of photographing the second image to form size tracking data; through the arranged area, the size change of the product contour can be intuitively seen;

[0138] When the size change is expanded by a preset proportion, the product category corresponding to the product contour is determined; the preset proportion is any value from 50% to 3 times;

[0139] Based on the product category, the first reminding information corresponding to the product category is extracted from the preset reminding information in the library;

[0140] The first reminding information is played through the second reminding module.

[0141] The working principle and beneficial effects of the above technical solution are:

[0142] When the door is opened, the outline of the commodity will change only when the user takes the commodity, so the user's taken commodity and the reminding information of the commodity can be determined through the outline change; the best operation for the embodiment is that the user takes the commodity in the parallel direction of the storage frame 1, and moves the commodity from the middle of the body 6 to the edge, so that the commodity is always increased on the corresponding second image acquisition module 4, so that the second reminding module can play the first reminding information, and the first reminding information includes the commodity type, the commodity price, the discount information and the like;

[0143] In one embodiment, the processing module 5 also performs the following operations:

[0144] Based on the second image, it is determined whether the storage frame 1 corresponding to the commodity taken by the user is the storage frame 1 in the second group;

[0145] When yes, the discount condition of the commodity taken by the user is determined;

[0146] Based on the discount condition, the second reminding information is generated; for example, when the discount condition is 80%, the second reminding information is that the discount of the commodity taken by you is 80% now, the original price is XX, and the discounted price is XX;

[0147] The second reminding information is played through the second reminding module.

[0148] The working principle and beneficial effects of the above technical solution are:

[0149] Under normal circumstances, one storage frame 1 places one commodity; however, due to the taking operation of different users, when the taking operation of the user is not standardized, for example, the user does not take the commodity from the A frame and then put it back into the A frame, but puts it into the B frame, causing the mixed loading condition; when the commodities are mixed, the second reminding module is needed to remind the user to know whether the taken commodity has a discount and the specific discount.

[0150] In one embodiment, the weighing vending machine with a continuous weighing system further comprises:

[0151] A plurality of second display modules 7 are arranged one by one on the side of the storage frame 1 close to the door of the body 6, and are respectively electrically connected with the processing module 5, and are used to display the information of the commodity in the corresponding storage frame 1.

[0152] The working principle and beneficial effects of the above technical solution are:

[0153] Through the display of the information of the commodity in the storage frame 1 through the second display module 7, the user can easily determine the price in each storage frame 1 and whether there is a discount.

[0154] Obviously, many modifications and variations of the present application are possible in light of the above teachings. It is, therefore, to be understood that within the scope of the appended claims and their equivalents, the application can be practiced otherwise than as specifically described.
