Further, referring to fig. 3, a second embodiment of the tracing management and control method for bulk commodities is provided.
In this embodiment, after step S30, the method further includes:
step S40: the user terminal receives bulk commodity buying and selling information input by a user and sends the bulk commodity buying and selling information to the background server;
step S50: the background server acquires corresponding stock information of the bulk commodity according to the purchase and sale information of the bulk commodity, and judges whether to carry out bulk commodity transaction according to the stock information of the bulk commodity and the purchase and sale information of the bulk commodity;
step S60: and the background server carries out bulk commodity transaction and updates the bulk commodity distribution information when the bulk commodity inventory information and the bulk commodity purchase and sale information meet transaction conditions.
It should be understood that the bulk commodity sales information includes buyer basic information, the type and quantity of bulk commodity to be purchased, the purchase unit price, the quality requirement for the commodity, and the like. Matching the stock information of the bulk commodity with the purchase and sale information of the bulk commodity, if the stock information of the bulk commodity can be matched with the stock information of the bulk commodity, performing bulk commodity transaction, sending the purchase and sale information of the bulk commodity to a user terminal of a buyer corresponding to the stock information of the bulk commodity, performing online communication between the buyer and the buyer, and if the transaction condition is met, achieving bulk commodity transaction, updating the distribution information of the bulk commodity according to the transaction information.
Further, before the step S20, the method further includes:
the user terminal receives a bulk commodity warehouse receipt application input by a shipper, extracts the quantity of bulk commodity assets from the bulk commodity warehouse receipt application, audits the quantity of bulk commodity assets to obtain an audit result, and sends the bulk commodity warehouse receipt application, the quantity of bulk commodity assets and the audit result to the background server;
the background server performs quality inspection on the stock of the bulk commodity to obtain a quality inspection result, and performs audit confirmation on the quantity of the bulk commodity assets to obtain an audit opinion;
the background server stores the bulk commodity warehouse receipt application and judges whether the warehouse receipt application is passed according to the audit result and the audit opinion;
and the background server generates warehouse receipt information when the warehouse receipt application is approved, and generates bulk commodity distribution information according to the warehouse receipt information.
Understandably, the manifest application includes information on the type of the bulk commodity, the quantity of assets, the quality of the commodity, the planting place of the bulk commodity product, and the like. In order to ensure the success rate of the trading, data analysis can be carried out on a large commodity order which is successfully traded in advance to obtain the minimum commodity trading quantity, and the minimum trading quantity is set to be the minimum asset quantity applied by a large commodity warehouse bill in the system. And auditing the quantity of the assets of the bulk commodity to obtain an auditing result, wherein the auditing result comprises the requirement of meeting the quantity of the assets and the requirement of not meeting the quantity of the warehouse bill assets. And when the quantity of the assets of the bulk commodity is more than or equal to the minimum quantity of the assets, the auditing result is that the quantity of the assets is met.
It should be noted that, the quality inspection of the inventory of the bulk goods can be performed by analyzing various product parameters of the bulk goods to obtain a quality inspection result. The stock of the bulk goods can be further shot in real time, and the appearance quality inspection of the color, the size and the like of the stock of the bulk goods is carried out according to the shot picture, so that the obtained appearance quality inspection result is used as one content of the quality inspection result.
In specific implementation, when the quality inspection result does not meet the product quality requirement, the warehouse receipt application is refused, and when the audit opinion of the quantity of the large commodity assets does not meet the warehouse receipt asset quantity requirement, the warehouse receipt application is refused. And when the quality inspection result meets the product quality requirement and the auditing opinion of the large commodity asset quantity meets the requirement of the quantity of the warehouse bill assets, approving the warehouse bill application. And generating warehouse receipt information, and generating bulk commodity distribution information according to the warehouse receipt information.
In this embodiment, the user terminal receives bulk commodity purchase and sale information input by a user, and sends the bulk commodity purchase and sale information to the background server, the background server obtains corresponding bulk commodity inventory information according to the bulk commodity purchase and sale information, and judges whether bulk commodity transaction is performed according to the bulk commodity inventory information and the bulk commodity purchase and sale information, and when the bulk commodity inventory information and the bulk commodity purchase and sale information satisfy transaction conditions, the background server performs bulk commodity transaction, updates the bulk commodity sales information, tracks each transaction of bulk commodities, updates the bulk commodity sales information in time, realizes whole traceability management and control of bulk commodities, and improves data timeliness and accuracy of traceability management and control of bulk commodities.
It should be noted that, in this document, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or system that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or system. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a process, method, article, or system that comprises the element.
The above-mentioned serial numbers of the embodiments of the present invention are merely for description and do not represent the merits of the embodiments. In the unit claims enumerating several means, several of these means may be embodied by one and the same item of hardware. The use of the words first, second, third and the like do not denote any order, but rather the words first, second and the like may be interpreted as indicating any order.
