Detailed Description
The present invention is described in terms of particular embodiments, other advantages and features of the invention will become apparent to those skilled in the art from the following disclosure, and it is to be understood that the described embodiments are merely exemplary of the invention and that it is not intended to limit the invention to the particular embodiments disclosed. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The unmanned vending machine is widely applied to daily life, and is shown in a scene diagram of the application of the unmanned vending machine in the invention shown in the attached figure 1; a user purchases a commodity on the unmanned vending machine; the user interacts with the unmanned vending machine through an interface; after the user finishes code scanning payment, the server receives the information of finishing payment and then issues an automatic goods delivery instruction to the unmanned vending machine; the unmanned vending machine can execute the shipment action after receiving the instruction issued by the server.
In the prior art, an http protocol is adopted between a server and an unmanned vending machine, and a VEM terminal sends a polling request to the server to determine that the vending machine can deliver goods at the time. The method has certain technical limitations, such as long response delay time of the shipment request, frequent request of the server, and higher load pressure on the server, and as the number of the unmanned terminal points sold increases, the protocol expansibility is insufficient, and the cost is higher.
Based on this, the invention provides a delivery control method of an unmanned vending machine, which is applied to a server and comprises the following steps:
after payment result information is received, issuing an instruction to the unmanned vending machine by adopting a WebSocket communication protocol;
the instructions include a shipment policy;
the shipment strategy comprises:
the method comprises a balance cargo channel polling shipment strategy, a single cargo channel priority shipment strategy, a cargo channel distance priority shipment strategy, a cargo channel state priority shipment strategy and a cargo channel weighting polling shipment strategy.
According to the method, due to the adoption of the WebSocket communication protocol, the server can actively push instructions to the unmanned vending machine; in the prior art, the unmanned vending machine actively follows the server to make a request through an HTTP (hyper text transport protocol), and if the number of the unmanned vending machines is huge, the server is overwhelmed; the response was slow. In the WebSocket protocol, a server can actively push an instruction; the command comprises a delivery strategy of the vending machine; thereby flexibly adjusting the delivery strategy.
In terms of functions, in terms of interaction functions, the user can only purchase one commodity after placing an order once, and the machine can only deliver one commodity after delivering the commodity once. The limitation lies in that the delivery requirement of purchasing a plurality of commodities by a user cannot be met, so that the user needs to perform multiple times of circulating operations (ordering, payment and goods taking processes), the user experience is reduced, and the repeated purchase desire of the user is influenced by overlong time consumed by the processes. In the goods taking process, after the goods in the single goods channel are blocked and abnormal, the failure of the goods channel can not be automatically removed, so that the subsequent goods in the goods channel can not be traded. In addition, the conventional vending machine single commodity delivery shipment process consumes a long time, if a user purchases a plurality of commodities, the time-consuming process is long, the user experience is poor, when the commodities are delivered and shipped, due to the fact that the single commodity channel sequential shipment mode is adopted, the fault tolerance rate is low, and once a problem is solved, the whole single commodity fails.
The invention adopts a multi-channel mode to deliver goods and adopts different strategies to deliver goods, thereby improving the success rate of delivering goods.
In one embodiment, the instructions further include identification, quantity, time of shipment, and status information for the items to be shipped; the state information includes: immediate effect, delayed effect. After receiving the instruction, the unmanned vending machine can carry out shipment according to the content.
Referring to fig. 1, a heartbeat mechanism is adopted between the server and the vending machine to determine that contact is maintained, and if the server does not receive heartbeat information sent by the vending machine, the server determines that the vending machine fails or determines that contact with the vending machine is lost. So that the server can send alarm information. To prompt the administrator to perform the overhaul.

excluding the cargo channels in abnormal state (maintenance, abnormal, temporary dispatch);
when each commodity needing to be delivered is delivered, determining the commodity channel with the highest weighted value as a delivery commodity channel on the premise that the residual quantity of the commodities needing to be delivered on the commodity channel is not zero; until the shipment is finished.
The core control module in the unmanned vending machine is internally provided with a dynamic goods channel planning algorithm and a planning mechanism. And dynamically planning the delivery sequence of the goods way according to the associated data. The data dimensions used include machine local commodity inventory quantity, commodity type, commodity age, commodity channel type (spring commodity channel, baffle commodity channel), commodity channel state (commodity channel available and unavailable), commodity channel distribution and the like. Shipment policy algorithm support includes, but is not limited to, lane balance polling, single lane first, lane distance first, lane status first, lane weighted polling, and the like. Thereby improving the delivery rate and bringing more convenience to users.
In order to dynamically mark the working state of the goods way; in one possible embodiment, the method further comprises: if receiving the failure information of the goods way; degrading the failed goods way;

Install infrared detector and sensor on the arm, can detect the number of piles that the goods were said and the position of goods way baffle, when commodity dropped the goods fill, can trigger and drop and detect the response.
When the goods channel breaks down (the partition plate blocks goods, and the spring blocks goods), the sensor cannot detect that the goods fall off, and error information and error codes are fed back to the goods channel control module. And if the goods channel control module receives the specified error code, the goods channel control module determines that goods delivery fails and returns the information to the core control module.
Retry of the failure: and the core control module classifies according to the shipment result data of the cargo channel on the same day, marks the status right drop or degradation of the cargo channel, and calls the cargo channel control module again to carry out shipment operation. When a single goods channel card fails, the weight of the goods channel is degraded, and the core control module informs the goods channel control module to retry one delivery operation. And after the current bill goods channel is blocked for 3 times continuously, the state of the goods channel is changed into the fault state. The status of the cargo way is updated to an unavailable status, including the number of retries.
After the commodity card was fought in the goods, the system can be when next user buys, and the window of getting goods is opened automatically, lets the user take away commodity. And (4) the goods passage marked as the fault is repaired and updated to be in a normal state in a manual mode.
3. Remote control instruction format: the core control module and the server interact with a custom message in a unified Json format, which is referred to as a message format shown in Table 1.
