[0058] Preferably, in the step S1, the goods to be pushed area of the vending machine is shot to obtain the image of the goods to be pushed area, which specifically includes:

[0059] When the vending machine receives a goods purchase instruction from a user, the matching goods are selected from the goods storage cabinet, and the selected goods are placed in the goods to be pushed area;

[0060] The goods to be pushed area is scanned and shot to obtain a panoramic image of the goods to be pushed area.

[0061] The beneficial effects of the above technical solutions are: when the user operates the man-machine interface of the automatic vending device, a corresponding goods purchase instruction is generated; at this time, the automatic retrieval device selects a matching goods from the goods storage cabinet and places the selected goods in the goods pushing area, wherein the goods pushing area can be, but is not limited to, a transfer storage space provided in the goods storage cabinet, which is used to connect the goods storage cabinet and the goods outlet area. When the selected goods are placed in the goods pushing area, the camera installed in the goods pushing area scans and photographs the internal space of the goods pushing area to obtain a panoramic image of the goods pushing area, which is convenient for further image recognition.

[0062] Preferably, in the step S1, analyzing and processing the image of the goods pushing area to determine the type of the goods currently existing in the goods pushing area specifically includes:

[0063] extracting an image frame corresponding to the selected goods from the panoramic image of the goods pushing area;

[0064] identifying and processing the image frame to obtain the outer packaging features of the selected goods;

[0065] determining the type of the selected goods and whether the outer packaging of the selected goods is complete or not according to the outer packaging features.

[0066] The beneficial effects of the above technical solutions are: the image frame corresponding to the selected goods is extracted from the panoramic image of the goods pushing area, and the color, character symbol, geometric shape and packaging surface structure of the image frame are identified and processed to obtain the color features, character symbol features, geometric shape features and packaging surface structure features on the outer packaging of the selected goods, so that the type of the selected goods and the completeness of the outer packaging can be accurately determined.

[0067] Preferably, in the step S2, when the goods are conveyed from the goods pushing area to the goods outlet area, the first weight change value of the goods storage cabinet of the automatic vending device before and after the goods are conveyed specifically includes:

[0068] when the outer packaging of the selected goods is complete, the selected goods are conveyed from the goods pushing area to the goods outlet area;

[0069] obtaining the first weight reduction value of the goods storage cabinet before and after the selected goods are conveyed.

[0070] The beneficial effects of the above technical solutions are: when the selected goods have complete and no defects in the outer packaging, the selected goods are directly conveyed from the goods to be pushed area to the delivery port area, and the first weight reduction value of the goods storage cabinet before and after the selected goods are conveyed is obtained, and the size of the first weight reduction value can accurately determine whether the selected goods have been pushed out. In addition, when the selected goods have incomplete and defects in the outer packaging, another goods is selected from the goods storage cabinet and placed in the goods to be pushed area, thereby ensuring the reliability of the device vending.

[0071] Preferably, in the step S2, generating the goods payment list according to the type of the goods and the first weight change value specifically includes:

[0072] According to the first weight reduction value, the number of the selected goods is determined; and according to the type of the selected goods, the unit price of the selected goods is determined.

[0073] According to the number and unit price of the selected goods, the goods payment list is generated; wherein the goods payment list includes a goods payment two-dimensional code.

[0074] The beneficial effects of the above technical solutions are: since the user can only select to purchase one or more goods of the same type at a time during the operation of the automatic vending device, and cannot purchase two different types of goods at the same time, the number of the selected goods can be determined according to the first weight reduction value and the weight of a single piece of goods; and according to the pre-set selling price of the device for each type of goods, the unit price of the selected goods can be determined according to the type of the selected goods. According to the number and unit price of the selected goods, the goods payment list is generated, and at this time, the user can realize contactless payment according to the payment method provided on the goods payment list.

[0075] Preferably, in the step S2, when the goods are conveyed from the goods to be pushed area to the delivery port area, it further includes

[0076] An auxiliary device is installed above the exit position of the delivery port area, and the auxiliary device includes two conveyors which are respectively installed at the falling pulley of the upper exit of the delivery port area, thereby assisting the conveying of the goods. First, according to the first weight change value and the second weight change value, it is judged whether the currently conveyed goods are stuck, and if the currently conveyed goods are stuck, according to the position of the goods in the to-be-pushed area before conveying and the time when the goods are stuck, the motion direction of the two conveyors of the auxiliary device and the motion intermittent frequency of the two conveyors are controlled, and the process is as follows:

[0077] In step S201, according to the first weight change value and the second weight change value, it is judged whether the currently conveyed goods are stuck by using the following formula (1),

[0078]

[0079] In the above formula (1), R(t) represents the determination value of whether the goods being conveyed at the current time is stuck; t represents the current time; t0 represents the time when the first weight change value is detected to be greater than 0 for the last time from the current time; G1(t0) represents the first weight change value at t0; T represents a preset time length, i.e., the falling conveying time reserved for the goods; V[G2(t0→t)=0] represents that all the detected second weight change values in the t0→t time period are all 0, at which time R(t)=1; ∧[G2(t0→t)>0] represents that there is a value greater than 0 in all the detected second weight change values in the t0→t time period, at which time R(t)=0;

[0080] If R(t)=0, it indicates that the goods being conveyed at the current time is not stuck, and the auxiliary device is not started;

[0081] If R(t)=1, it indicates that the goods being conveyed at the current time is stuck, and the auxiliary device is started;

[0082] In step S202, if the goods being conveyed at the current time is stuck, the auxiliary device is started, and the moving direction of the two conveyors on the auxiliary device is controlled according to the position of the goods in the waiting pushing area before conveying by using the following formula (2)

[0083]

[0084] In the above formula (2), F in represents the moving direction of the inner conveyor in the auxiliary device; F out represents the moving direction of the outer conveyor in the auxiliary device; a represents the position of the goods in the waiting pushing area before conveying, which is the a-th goods storage cabinet counted from right to left with the gate direction as the forward direction; and n represents the total number of the goods storage cabinets above the waiting pushing area.

[0085] If F in , F out is a positive value, the corresponding conveyor is controlled to rotate to the right with the gate direction as the forward direction; if F in , F out is a negative value, the corresponding conveyor is controlled to rotate to the left with the gate direction as the forward direction, so as to drive the goods to fall and convey to the goods outlet area by controlling the moving direction of the two conveyors.

[0086] In step S203, if the goods being conveyed at the current time is stuck, the moving intermittent frequency of the two conveyors of the auxiliary device is controlled according to the time when the goods is stuck by using the following formula (3)

[0087]

[0088] In the above formula (3), f(t) represents the motion interval frequency value calculated using the above formula (3) from the current moment when the previous intermittent motion ends or when the auxiliary device is started; f m This represents the minimum intermittent frequency value of the two conveyor belts on the auxiliary device; f M This indicates the maximum intermittent frequency value of the two conveyor belts on the auxiliary device;

[0089] Through the above process, the two conveyor belts move intermittently along their respective directions of motion, i.e., they move... Stop after time The time required causes the two conveyor belts to vibrate the cargo through intermittent movement during their operation, driving the cargo to fall and be transported to the outlet area.

[0090] The beneficial effects of the above technical solution are as follows: Using the above formula (1), the first weight change value and the second weight change value are used to determine whether the conveyed goods are stuck. When stuck, the auxiliary device is activated, and when the goods are not stuck, the auxiliary device is not activated, so as to achieve the effect of intelligent energy saving. Then, using the above formula (2), the movement direction of the two conveyor belts on the auxiliary device is controlled according to the position of the goods in the push area before the conveying. Thus, by controlling the movement direction of the two conveyor belts, the goods are helped to fall and be conveyed to the outlet area. At the same time, the heavier end of the goods can be rotated to the middle of the outlet area to prevent the heavier end of the goods from hitting the side plates of the vending machine, thereby preventing the goods from getting stuck more seriously. Finally, using the above formula (3), the movement interval frequency of the two conveyor belts on the auxiliary device is controlled according to the time when the goods are stuck. Thus, the two conveyor belts generate a certain vibration on the goods through intermittent movement during the movement, thereby more effectively helping the goods fall and be conveyed to the outlet area.

[0091] Preferably, in step S3, adjusting the gate opening / closing status of the shipping area based on the payment status of the goods payment list specifically includes:

[0092] If payment for the goods has been completed within a preset timeframe, the gate of the shipping area will be opened.

[0094] The beneficial effects of the above technical solutions are that when the user completes the payment operation on the goods payment list within the preset time range, the gate of the delivery outlet area is automatically opened, facilitating the user to take out the goods from the delivery outlet area. When the user does not complete the payment operation on the goods payment list within the preset time range, the delivery outlet gate is maintained in a closed state, the selected goods are returned from the delivery outlet area to the goods storage cabinet, and the validity of the goods payment list is cancelled, that is, the current user's transaction operation on the vending machine is terminated.

[0095] Preferably, in the step S3, a second weight change value corresponding to the delivery outlet area within a preset time range is obtained, and the second weight change value is used to adjust the gate opening and closing state of the delivery outlet area again. Specifically, the step S3 comprises the following steps:

[0096] The second weight reduction value corresponding to the delivery outlet area within a preset time range is obtained. If the second weight reduction value is zero, it indicates that the gate of the delivery outlet area returns to the closed state, and the selected goods are returned from the delivery outlet area to the goods storage cabinet. According to the goods payment list, a refund operation is performed.

[0097] The beneficial effects of the above technical solutions are that when the second weight reduction value corresponding to the delivery outlet area within a preset time range is zero, it indicates that the user completes the payment operation on the goods payment list and does not remove the goods from the delivery outlet area. At this time, the gate of the delivery outlet area is instructed to return to the closed state and the selected goods are returned from the delivery outlet area to the goods storage cabinet, which can avoid the goods being taken away by other personnel. According to the goods payment list, a refund operation is performed, thereby terminating the current transaction of the user on the vending machine.

[0098] Preferably, in the step S4, the out-of-stock state information is used to send a restocking notification message to the management platform terminal, and the restocking notification message comprises the following information:

[0099] The out-of-stock state information is used to send a restocking notification message to the management platform terminal, and the restocking notification message comprises the following information: the location information of the vending machine, and the type and quantity of goods that need to be restocked.
