Technical Field

[0001] The present invention relates to the technical field of blockchain, and more particularly to a method and system for monitoring stored goods in warehouses based on blockchain light nodes. Background Art

[0002] Warehouse receipt pledge financing is the main type of business in the field of supply chain finance. It belongs to the movable property pledge business of logistics and warehousing enterprises. It is the behavior of warehousing and logistics enterprises with a certain inventory value, under the premise of core enterprise guarantee, using warehouse receipts to pledge financing to banks and other financial institutions. The warehouse receipt itself represents the right to pick up the goods, and the core enterprise (usually a third-party logistics company) bears the risk of damage to its own funds due to changes in the value of the pledged warehouse receipt, changes in the value of the pledged inventory, or damage to the goods. In order to ensure that the value of the pledged warehouse receipt is not lost when the warehousing and logistics enterprises manage the stored goods, it is necessary to strictly control the stored goods corresponding to the pledged warehouse receipts. At the same time, it is also necessary to provide banks and other financial institutions with reliable and transparent monitoring methods, which is conducive to promoting warehouse receipt pledge financing.

[0006] After obtaining the entry request sent by the goods storage requester or the exit request sent by the goods right owner, the blockchain full node generates corresponding first status information according to the entry goods information carried by the entry request or the exit goods information carried by the exit request, and synchronizes the generated first status information to the blockchain light node configured on the monitoring device for video monitoring of the storage area corresponding to the storage area code according to the storage area code carried by the entry request or the exit request;

[0007] After obtaining the first state information, the blockchain light node monitors in real time whether the corresponding monitoring device generates the second state information, and if the second state information is generated, obtains the second state information, and compares the first state information with the second state information to generate a state comparison result, and after generating the state comparison result, synchronizes the state comparison result to the blockchain full node;

[0008] After obtaining the status comparison result, if the status comparison result indicates that the status is abnormal, the blockchain full node sends an early warning prompt message to the owner of the goods mapped by the incoming request or the outgoing request.

[0009] According to a specific implementation, the storage goods in-warehouse monitoring method based on blockchain light node of the present invention further includes: after obtaining the warehousing request sent by the goods storage requester, the blockchain full node determines whether the warehousing request carries a warehousing area code, and if not, allocates an empty storage area to the warehousing request; and, the warehousing area code corresponding to the warehousing request, the goods ownership information carried by the warehousing request, and the warehousing goods information are uploaded to the chain as warehousing records;

[0010] After obtaining the outbound delivery request sent by the owner of the delivery right, the blockchain full node will upload the storage area code, cargo ownership information and outbound cargo information carried in the outbound delivery request as a storage record.

[0011] According to a specific implementation, in the storage goods in-warehouse monitoring method based on the blockchain light node of the present invention, the entry request carries the signature information of the goods storage requester and the goods owner; the exit request carries the signature information of the goods owner; and before the storage record is uploaded to the chain, the blockchain full node verifies the signature information carried by the entry request or the exit request, and uploads the storage record to the chain after the signature information is verified.

[0012] According to a specific implementation, in the warehouse storage monitoring method based on the blockchain light node of the present invention, the incoming goods information and the outgoing goods information both include: goods size data and goods quantity data; the blockchain full node generates the first status information for characterizing the size of the storage space occupied by the goods to be entered or the goods to be shipped based on the goods size data and the goods quantity data.

[0013] According to a specific embodiment, the method for monitoring stored goods in warehouse based on blockchain light nodes of the present invention also includes: configuring the monitoring device to use the storage area in its monitoring screen as an area of ​​interest, and identifying contour data of objects in the area of ​​interest, and generating the second status information for characterizing the change in the storage space occupied by the goods in warehouse before and after the entry or exit operation based on the contour data of the objects in the area of ​​interest before and after the entry or exit operation.

[0014] According to a specific implementation, the method for monitoring stored goods in warehouse based on blockchain light nodes of the present invention also includes: after the signature information is verified, the blockchain full node assigns the corresponding warehouse manager to the entry request or the exit request to perform the entry operation or the exit operation, and synchronizes the identity information of the assigned warehouse manager and the first status information to the corresponding blockchain light node.

[0015] According to a specific implementation, the storage goods in-warehouse monitoring method based on blockchain light node of the present invention further includes: after obtaining the identity information of the warehouse manager, the blockchain light node monitors in real time whether its corresponding monitoring device recognizes the face information through the monitoring screen, if the face information is recognized, then the face information is obtained, and it is determined whether the face information matches the obtained identity information of the warehouse manager; if not, the face information is synchronized to the blockchain full node;

[0016] After obtaining the facial information, the blockchain full node determines whether the facial information matches the identity information of the warehouse manager corresponding to the other inbound request or the outbound request. If not, an early warning message is sent to the owner of the goods mapped by the inbound request or the outbound request.

BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Figure 1 This is a flow chart of the storage goods in-warehouse monitoring method based on blockchain light node of the present invention;

[0026] Figure 2This is a schematic diagram of the architecture of the warehouse storage monitoring system based on blockchain light nodes of the present invention. DETAILED DESCRIPTION

[0027] The present invention is further described in detail below in conjunction with test examples and specific implementation methods. However, this should not be understood as the scope of the above subject matter of the present invention being limited to the following embodiments, and all technologies realized based on the content of the present invention belong to the scope of the present invention.

[0028] like Figure 1 As shown, the storage material in-warehouse monitoring method based on blockchain light node of the present invention includes:

[0029] After obtaining the entry request sent by the goods storage requester or the exit request sent by the goods right owner, the blockchain full node generates corresponding first status information according to the entry goods information carried by the entry request or the exit goods information carried by the exit request, and synchronizes the generated first status information to the blockchain light node configured on the monitoring device for video monitoring of the storage area corresponding to the storage area code according to the storage area code carried by the entry request or the exit request;

[0030] After obtaining the first state information, the blockchain light node monitors in real time whether the corresponding monitoring device generates the second state information, and if the second state information is generated, obtains the second state information, and compares the first state information with the second state information to generate a state comparison result, and after generating the state comparison result, synchronizes the state comparison result to the blockchain full node;

[0031] After obtaining the status comparison result, if the status comparison result indicates that the status is abnormal, the blockchain full node sends an early warning message to the owner of the goods mapped by the entry request or the exit request. In implementation, both the entry request and the exit request carry the information of the owner of the goods. Of course, the owner of the goods at the time of entry and the owner of the goods at the time of exit may change with the pledge or change of the goods, and the change of the owner of the goods can be recorded through the blockchain.

[0032] In one embodiment, the storage goods in-warehouse monitoring method based on blockchain light node of the present invention further includes: after obtaining the warehousing request sent by the goods storage requester, the blockchain full node determines whether the warehousing request carries a storage area code, and if not, allocates an empty storage area to the warehousing request; and, the storage area code corresponding to the warehousing request, the goods ownership information carried by the warehousing request, and the warehousing goods information are uploaded to the chain as warehousing records;

[0033] After obtaining the outbound delivery request sent by the owner of the delivery right, the blockchain full node will upload the storage area code, cargo ownership information and outbound cargo information carried in the outbound delivery request as a storage record.

[0034] In one embodiment, in the storage monitoring method based on blockchain light node of the present invention, the entry request carries the signature information of the party requesting the storage of the goods and the party with the right to the goods; the exit request carries the signature information of the party with the right to the goods; and before the storage record is put on the chain, the blockchain full node verifies the signature information carried by the entry request or the exit request, and puts the storage record on the chain after the signature information is verified. Specifically, by verifying the signature information of the entry request and the exit request, it is helpful to identify the identity authority of the party requesting the storage of the goods or the party with the right to the goods, and at the same time, the storage record is put on the chain for evidence, which can ensure the credibility of the party requesting the storage and the party with the right to the goods.

[0035] In one embodiment, in the storage monitoring method based on blockchain light node of the present invention, the inbound goods information and the outbound goods information both include: goods size data and goods quantity data; the blockchain full node generates the first state information for characterizing the size of the storage space occupied by the goods to be in or out based on the goods size data and the goods quantity data. During implementation, a general cargo volume algorithm is adopted, that is, the size of a single cargo*the quantity of cargo (the volume compression that may occur in the state of cargo placement can also be considered, and the corresponding compression coefficient can be introduced). This is not the focus of the technical solution of the present invention and will not be elaborated.

[0036] In one embodiment, the storage goods in-warehouse monitoring method based on blockchain light node of the present invention further includes: configuring the monitoring device to use the storage area in its monitoring screen as the area of ​​interest, and identifying the contour data of the objects in the area of ​​interest, and generating the second state information for characterizing the change in the size of the storage space occupied by the goods in the warehouse before and after the entry or exit operation according to the contour data of the objects in the area of ​​interest before and after the entry or exit operation. During implementation, a general target contour calculation algorithm based on image recognition is used to calculate the contour data of the goods placed in the storage area. This is not the research focus of the technical solution of the present invention and will not be repeated here.

[0037] In one embodiment, the method for monitoring stored goods in warehouse based on blockchain light nodes of the present invention also includes: after the signature information is verified, the blockchain full node assigns the corresponding warehouse manager to the entry request or the exit request to perform the entry operation or the exit operation, and synchronizes the identity information of the assigned warehouse manager and the first status information to the corresponding blockchain light node.

[0038] In one embodiment, the storage material in-warehouse monitoring method based on blockchain light node of the present invention also includes: after obtaining the identity information of the warehouse manager, the blockchain light node monitors in real time whether its corresponding monitoring equipment recognizes facial information through the monitoring screen; if facial information is recognized, the facial information is obtained, and it is determined whether the facial information matches the obtained identity information of the warehouse manager; if not, the facial information is synchronized to the blockchain full node; during implementation, a general image recognition-based facial feature calculation algorithm is used to realize the identity recognition of personnel in the storage area, which is not the research focus of the technical solution of the present invention and will not be elaborated here.

[0039] After obtaining the facial information, the blockchain full node determines whether the facial information matches the identity information of the warehouse manager corresponding to the other inbound or outbound requests. If not, a warning message is sent to the owner of the goods mapped to the inbound or outbound request. During implementation, the identity information of all warehouse managers is recorded on the blockchain, which can realize the identity comparison of facial information.

[0040] In one embodiment, in the storage goods in-warehouse monitoring method based on blockchain light node of the present invention, the state comparison result and the face information synchronized from the blockchain light node to the blockchain full node both carry the storage area code corresponding to the blockchain light node;

[0041] Moreover, after obtaining the entry request sent by the cargo storage requester or the exit request sent by the cargo right owner, the blockchain full node assigns an entry path or an exit path to the entry request or the exit request, and uploads the entry path or the exit path to the chain;

[0042] After obtaining the facial information, if the blockchain full node determines that the facial information matches the identity information of the warehouse manager corresponding to the other inbound request or the outbound request, it determines whether the storage area code carried by the facial information belongs to the storage area code sequence corresponding to the inbound path or the outbound path when it passes through the relevant storage area. If not, the blockchain full node sends an early warning prompt message to the owner of the goods mapped by the inbound request or the outbound request.

[0043] During implementation, since warehouse managers will inevitably pass through other storage areas to reach the designated storage area, by planning the entry or exit path, the warehouse managers' entry or exit operations can be restricted, which can achieve reliable and transparent management within the warehouse management party, increase the trust of the cargo owners, and help promote warehouse receipt pledge financing.

[0044] In one embodiment, the status comparison result or the facial information of the blockchain light node synchronized to the blockchain full node is recorded on the blockchain in the form of the storage area code carried by it as the key value with the status comparison result or the facial information as the Value value.

[0045] like Figure 2 As shown, the present invention also provides a storage material in-warehouse monitoring system based on blockchain light nodes, which includes: a plurality of monitoring devices, and a blockchain network composed of a plurality of blockchain light nodes and a plurality of blockchain full nodes; and, each monitoring device is configured with a corresponding blockchain light node, so that the storage material in-warehouse monitoring method based on blockchain light nodes provided by the present invention can be realized through the interaction between a plurality of monitoring devices and blockchain light nodes, and between blockchain light nodes and blockchain networks.
