Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
As shown in fig. 1 and 2, the present application provides a control method for a vending machine, the vending machine includes a cabinet, a goods taking port is provided on a surface of the cabinet, a goods channel for storing goods and a goods bucket for transporting goods to the goods taking port along the goods channel according to a goods storage position are provided inside the cabinet. The user can select the needed commodities through a human-computer interaction device arranged on the cabinet or a mobile terminal connected with the cabinet.
Specifically, the control method of the vending machine comprises the following steps:
step S1, obtaining a purchasing instruction of the commodity, wherein the purchasing instruction comprises purchasing information and user information of at least one commodity; after the user selects the goods required to be purchased and the payment is completed, the purchase instruction of the user is automatically generated. Each purchase instruction comprises purchase information of the commodity and information of the user, so that a corresponding delivery scheme can be generated according to the purchase instruction.
And step S2, determining the purchase information and the quantity of the commodities required to be purchased according to the purchase instruction, and making a delivery scheme of the types and the quantity of the commodities. After the purchase instruction is obtained, the purchase information and the quantity of the commodities required to be purchased are determined according to the purchase instruction, and whether the quantity of the commodities is sufficient or not is judged through storage positions of all the stored commodities. And if the goods are out of stock and the goods are not in stock, stopping the goods delivery of the goods, and sending an inquiry instruction to the user to inquire whether the user needs to modify and purchase the goods. And confirming the order after the user replies, updating the purchase instruction and making a delivery scheme according to the latest purchase order.
Specifically, the step S2 further includes the following steps:
s21, sequencing the commodities contained in the purchase instruction, inquiring the commodities which can be delivered in the purchase instruction, and constructing a structure linked list; the structure linked list includes the position of each commodity capable of being delivered, that is, the position of the commodity channel, the quantity of the commodity and the parameters of the commodity. In practical situations, it may be difficult to send out all the products at once because the user needs to purchase a plurality of products and the parameters of each product are different. Therefore, the information required by the commodities is presented in the same table by constructing the structure linked list of the purchase instruction, so that the subsequent rapid formulation of the shipment plan is facilitated, and the shipment efficiency is improved.
And step S22, calculating the shipment scheme of the commodities in the current purchase instruction according to the parameters and the quantity of the commodities in the structure linked list by using an extent strategy and a depth strategy, wherein the shipment scheme at least comprises the shipment sequence of each batch of commodities and the motion trail of a cargo bucket.
Because the position that every commodity was placed is different, appears the goods fill once the unable condition of accomplishing all commodities of transportation easily in the transportation, perhaps because the deviation appears in commodity locating place, the goods fill can transport another commodity but the problem that commodity damaged appears easily, consequently adds the breadth strategy in this application. The breadth strategy is to calculate a horizontal projection superposition coefficient according to the transverse coordinate position of the goods channel, determine the collision coefficient of the goods falling between the goods channels, sort the structural linked list according to the collision coefficient, the parameters and the quantity of the goods channel and the vertical height of the goods channel from large to small after superposition, and select the goods selected in the same batch according to the arrangement sequence. That is, the lower the collision coefficient of the lane, the larger the number of the articles in the lane, the larger the vertical height of the lane, and the articles in the same purchase order in the vicinity are preferred. This facilitates the bucket to take more items at a time during shipment, with a minimum of batches of more items.
More, because the situation that all goods cannot be transported at one time easily occurs in the transportation process, and the bucket needs to spend a certain time in the transportation of the goods channel, the depth strategy is additionally arranged on the basis of the breadth strategy. The depth strategy is to calculate the motion trail of the goods bucket on the basis of the breadth strategy, sort according to the length of the motion trail of the goods bucket and select the delivery scheme with the shortest motion trail of the goods bucket.
Further, the step S22 includes: acquiring the parameter specification of the goods bucket and the parameters of the goods, judging whether the goods bucket can finish all the goods in one-time transportation, if so, selecting the delivery scheme as the one-time transportation of the goods bucket, and directly calculating through a depth strategy; and if not, calculating the shipment scheme through the breadth strategy. Further, the step S22 includes: and acquiring the parameter specification of the cargo bucket, acquiring the space geometric parameter information of the commodity according to the breadth strategy, and determining the commodity selected in the same batch according to the parameter specification and the space geometric parameter information. Since the goods are not regularly stacked inside the bucket, the parameters of the bucket include the bearing surface area, the volume, the standard load capacity and the contour dimension of the bucket, and the space geometry parameters of the goods include the weight, the bottom area and the contour dimension of the goods. And judging the maximum delivery volume of the cargo bucket according to the parameter specification of the cargo bucket and the space geometric parameters of the commodities.
And step S3, controlling the bucket to convey the commodity to the goods taking port along the goods channel according to the goods delivery scheme.
The control method that this application provided can formulate different shipment schemes according to the kind and the purchase quantity that the user purchased commodity, according to order and batch that the alternative shipment of formulation of purchase instruction was delivered, solves the problem that current automatic vending machine can't a batch of shipment many commodities, practices thrift shipment time, improves shipment efficiency, improves automatic vending machine's use and experiences.
The embodiment also provides an automatic vending machine, which comprises a cabinet, wherein the surface of the cabinet is provided with a goods taking opening, a goods channel for storing goods and a goods hopper for conveying the goods to the goods taking opening along the goods channel according to the goods storage position are arranged in the cabinet; the cabinet is internally provided with a plurality of processors, a memory and a computer program which is stored on the memory and can run on the processors, and the plurality of processors realize the control method of the vending machine when executing the computer program.
The embodiment of the invention also provides a storage medium, wherein the storage medium is stored with computer executable instructions, and the computer executable instructions can execute the method for detecting the DNS spoofing attack in any method embodiment. The storage medium may be a magnetic disk, an optical disk, a Read-Only Memory (ROM), a Random Access Memory (RAM), a Flash Memory (Flash Memory), a hard disk (hard disk Drive, abbreviated as HDD), a Solid State Drive (SSD), or the like; the storage medium may also comprise a combination of memories of the kind described above.
