For example, the first information may also be referred to as second information, and similarly, the second information may also be referred to as first information, without departing from the scope of the present specification. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.

In the related art, warehouse security presents a security risk caused by the private retrieval of stored items. Although the efficiency of managing and maintaining the stored articles can be improved to a certain extent through the electronic tags, the possibility of malicious invasion exists in a warehouse system, and the electronic tags have the defect of easy counterfeiting, so that information related to the electronic tags can be acquired artificially, and two identical electronic tags are generated, so that warehouse managers can not know whether the articles bound with the electronic tags in the warehouse are stolen or privately used. In addition, even if the stolen or privately used article is located through post-investigation, the economic loss of the user is caused by missing the best early warning time. Therefore, the present specification proposes the following technical solutions to solve the above problems.

Fig. 1 is a schematic diagram of an architecture of a block chain-based warehouse management system according to an exemplary embodiment of the present disclosure. As shown in fig. 1, may include a tag reader 11, an environmental monitoring sensor 12, an early warning platform 13, and a blockchain system 14.

The tag reader 11 is an electronic device that can read data contained in an electronic tag within a certain range based on a Radio Frequency Identification (RFID) technology. In the operation process of the system, the tag reader 11 may read the electronic tag corresponding to the article when the use state of the article changes, and send a use state change notification for the article to the early warning platform.

The environment monitoring sensor 12 refers to an electronic device that can collect and monitor one or more kinds of data in an environment based on preset dimensions, such as: entrance guard's check out test set, temperature and humidity measurement equipment, supervisory equipment etc. this one or more embodiments of this specification do not limit this. In the operation process of the system, the environmental monitoring sensor 12 may acquire environmental data of the warehouse and send the environmental data to the early warning platform.

The early warning platform 13 is a network device supporting data transmission and processing functions, and in the system operation process, the early warning platform 13 is connected with the blockchain system 14. When the early warning platform receives the usage status change notification and the environmental data, the usage status change notification and the environmental data can be stored in the blockchain system 14. Meanwhile, an abnormal verification result for the to-be-verified article can be generated in response to the abnormal verification request for the to-be-verified article, and whether early warning is triggered or not is judged according to the abnormal verification result. The early warning platform 13 may be respectively built by a physical server of an independent host, or a virtual server carried by a host cluster, which is not limited in this specification.

The blockchain system 14 may maintain one or more blockchains (e.g., public blockchains, private blockchains, federation blockchains, etc.) and include a plurality of blockchain nodes for carrying the one or more blockchains; for example, block chain node 1, block link point 2, block link point 3, block link point 4, block link point i, etc. may collectively carry one or more block chains. Between blockchains included in the blockchain system 14, cross-chain data access is possible. The blockchain system 14 may be a physical host in the server cluster, or may be a virtual machine created by virtualizing hardware resources mounted on the server or the server cluster based on a virtualization technology. Each blockchain node can be connected together by various types of communication methods (such as TCP/IP) to form a network so as to carry one or more blockchains. The one or more embodiments of the present description are not intended to be limiting. In the system operation process, the blockchain system 14 may store the usage state change notification and the environmental data submitted by the early warning platform, and may query the usage state change notification of the to-be-verified item and the environmental data of the warehouse in the generation process of the abnormal verification result.

It should be noted that fig. 1 is a schematic diagram of an architecture of a warehouse management system based on a blockchain as an exemplary embodiment, which only shows an implementation manner of the system, and as an example of a data query Transaction below, an early warning platform 13 may generate a data query Transaction (Transaction) as a data query request below, and send the data query Transaction to any node of the blockchain system 14. After receiving the data query request, any node of the blockchain system 14 may perform any of the following operations: the aforementioned node synchronizes the aforementioned data query transaction to other nodes in the blockchain system 14, and under the condition that the aforementioned data query transaction is easy to achieve consensus between the aforementioned node and the aforementioned other nodes, the aforementioned node can execute the aforementioned data query transaction, and meanwhile, the early warning platform 13 monitors and obtains the generated query result; any node directly executes the data query transaction locally, and meanwhile, the early warning platform 13 monitors and acquires the generated query result.

The system may also have other implementation manners, for example, the Blockchain system 14 may further include a BaaS platform (also referred to as a BaaS cloud) of a Blockchain as a Service (BaaS) on the basis shown in fig. 1, and the BaaS platform may provide a pre-programmed software manner for activities (such as subscription and notification, user verification, database management, and remote update) occurring on the Blockchain system 14, and provide a simple and efficient Blockchain Service for the early warning platform 13 connected to the BaaS platform, so as to accelerate development, testing, and online of application related to the Blockchain, and assist landing of a corresponding Blockchain commercial application scenario. Still taking the following data query transaction as an example, the early warning platform 13 may initiate a data query request to the BaaS platform, and after receiving the data query request, the BaaS platform generates a corresponding data query transaction, and sends the data query transaction to any node of the blockchain system 14. After receiving the data query transaction, any node of the blockchain system 14 may perform any of the following operations: the aforementioned any node synchronizes the data query transaction to other nodes in the blockchain system 14, and under the condition that the data query transaction is easy to achieve consensus between the aforementioned any node and the aforementioned other nodes, the aforementioned any node can execute the data query transaction, and return the generated query result to the early warning platform 13 via the BaaS platform; any node directly executes the data query transaction locally, and returns a generated query result to the early warning platform 13 through the BaaS platform.

The connection between the tag reader 11, the environment monitoring sensor 12, the early warning platform 13 and the blockchain system 14 may include various types of wired or wireless connections, which is not limited in this specification.

Fig. 2 is a schematic diagram illustrating a multi-party interaction of a block chain-based warehouse management system according to an exemplary embodiment of the present disclosure. As shown in fig. 2, the system may include a tag reader, an environmental monitoring sensor, an early warning platform, and a blockchain system; the system may comprise the following interactive steps:

s201, the tag reader reads the electronic tag corresponding to the article.

When the use state of the stored article in the warehouse changes, the tag reader can read the electronic tag corresponding to the article and send a use state change notification for the article to the early warning platform.

The usage state change notification may include identification information of the article read from the electronic tag to indicate that the usage state change notification corresponds to the article. In other words, the following exception checking result may be generated by cross-checking the usage state change notification corresponding to the identification information included in the above exception checking request with the environment data of the warehouse.

The identification information can be generated by different devices based on different rules according to actual requirements.

In an embodiment, the identification information of the article may be an Electronic Product Code (EPC) of the Product. The EPC code may be information generated by a manufacturer in a production process of the electronic tag by initiating a digital identity issuance transaction to a blockchain system. The blockchain system may invoke a digital identity issuance contract indicated by the digital identity issuance transaction according to the received digital identity issuance transaction, so that the digital identity issuance contract generates an EPC code as the identification information of the item. In this embodiment, since the EPC code itself has uniqueness and the data generated in the blockchain system has security, the identification information is difficult to be stolen or tampered by a person, thereby ensuring the security and uniqueness of the electronic tag and the corresponding article.

The use state change notification may indicate that the use state of the article has changed. When the electronic tag is designed to be a physical structure destroyed along with the use of the article, the change can be that the use state of the article is changed from 'unused' to 'used'; or, when the electronic tag corresponding to the article enters the reading range from the outside of the reading range of the tag reader, or moves out of the reading range, the change may be that the article is changed from "unused" to "used"; alternatively, when the position of the electronic tag corresponding to the article is changed within the reading range, the change may be a change from "unused" to "used" in the use state of the article. The use state of the article may be set to a state such as "to be used", "used twice", "destroyed", "unknown", etc. according to actual situations, which is not limited in this specification.

In the present specification, the change in the position of the electronic tag corresponding to the article in the reading range is not limited. The change may be predefined, for example, a motion track is predefined, and the tag reader determines that the use state of the article has changed only when the electronic tag corresponding to the article moves according to or not according to the motion track within the reading range; alternatively, the change may be non-predefined, for example, when any change is transmitted from the position of the electronic tag corresponding to the article within the reading range, the tag reader may determine that the use state of the article has changed.

S202, the environment monitoring sensor acquires environment data of the warehouse.

The environment monitoring sensor can acquire the environment data of the warehouse and send the environment data to the early warning platform, and then the environment data is stored and verified to the block chain system.

The environment data can be set to information based on different dimensions according to different forms and functions of the environment monitoring sensor. For example: when the environment monitoring sensor is an access control device, the environment data can be recorded by personnel entering and exiting the access control device; or when the environment monitoring sensor is a monitoring device, the environment data can be a human body detection record in a designated area; or when the environment monitoring sensor is an article calling device such as a mechanical arm, an escalator or the like, the environment data can call records for applications related to the article calling device. This is not a limitation in the present description.

It should be noted that, no strict order requirement exists between S201 and S202, on one hand, the time for the tag reader to read the electronic tag corresponding to the article is determined according to the time when the use state of the article changes, and a fixed operation rule does not exist in an actual application scenario; on the other hand, the environment monitoring sensor may periodically acquire the environment data of the warehouse according to a preset monitoring time point or a monitoring interval, and ye may actively acquire the environment data of the warehouse according to a manual operation, which is not limited in this specification.

S203, the tag reader sends a use state change notification to the early warning platform.

And S204, the environment monitoring sensor sends environment data to the early warning platform.

The usage state change notification and the environment data may respectively include corresponding data reading time stamps and data obtaining time stamps, so as to facilitate the execution of the following cross-validation process.

It should be noted that, similar to S201 and S202, there is no strict order requirement between S203 and S204, the tag reader and/or the environment monitoring sensor may send corresponding data to the early warning platform immediately under the condition of acquiring the corresponding data, or temporarily store the corresponding data in a local storage space until a preset sending condition is met, and then send the data in the local storage space to the early warning platform together, where the preset sending condition may be 12 hours per time interval, or the number of data is greater than 10, and this is not limited in this specification.

S205, the early warning platform sends the received using state change notice and the environmental data to the block chain system.

According to different structures of the blockchain system, the early warning platform can send and receive the use state change notification and the environment data to the blockchain system in different modes. For example: when the blockchain system does not have the BaaS platform, the early warning platform can initiate a data certification transaction including the use state change notification and the environment data to the blockchain system, so that the blockchain system is certified in the blockchain system; when the blockchain system has a BaaS platform, the early warning platform may initiate a data certification request including the usage state change notification and the environment data to the BaaS platform of the blockchain system, and the BaaS platform may initiate a data certification transaction including the usage state change notification and the environment data to any node in the blockchain system according to the data certification request, so that the blockchain system is certified in the blockchain system.

For example, as described above, in an actual application scenario, the execution time and the sequence of S203 and S204 may not be accurately predicted, so that the early warning platform does not need to send the usage state change notification to the blockchain system together with the environmental data, and the early warning platform may directly send the usage state change notification to the blockchain system after receiving the data, or send the usage state change notification to the blockchain system under a specific condition according to a preset rule, which is not limited in this specification.

S206, the blockchain system uses the state change notification and the environment data for evidence storage.

According to different actual requirements, the block chain system can store the use state change notification and the environmental data in different modes, so that a data acquiring link of the warehousing management system is completed. The use state change notification and the environmental data are both stored and certified in the block chain, so that the possibility of artificial tampering and leakage of the use state change notification and the environmental data can be avoided, uniqueness and safety of the use state change notification and the environmental data are guaranteed, and accuracy of the following early warning is improved.

In an embodiment, after receiving the data authentication transaction, the blockchain system may store the usage state change notification and the environment data included in the data authentication transaction into a corresponding blocky block based on a common identification mechanism, so that the blockchain system may obtain the usage state change notification and the environment data in a following cross check process.

In another embodiment, after receiving the data verification transaction, the blockchain system may store the usage state change notification and the environment data included in the data verification transaction into a corresponding contract state by creating an intelligent contract, so that the blockchain system may obtain the usage state change notification and the environment data by invoking the intelligent contract in a following cross check process.

The manner of creating and invoking the intelligent contracts may refer to the manner shown in fig. 3a and 3 b. Fig. 3a is a schematic diagram illustrating a manner of creating a blockchain intelligent contract according to an exemplary embodiment of the present specification, and fig. 3b is a schematic diagram illustrating a manner of invoking a blockchain intelligent contract according to an exemplary embodiment of the present specification.

As shown in fig. 3a, after Bob may send a transaction to the blockchain system that includes contract code creating intelligent contract creation information, each node device may execute the transaction in the piggybacked virtual machine. The From field of the transaction in fig. 3a is used To record the address of the account initiating the creation of the intelligent contract, the contract code stored in the field value of the Data field of the transaction may be the above byte code, and the field value of the To field of the transaction is a null account. After the nodes reach the agreement through the consensus mechanism, the intelligent contract is successfully created, and the follow-up user can call the intelligent contract. After the intelligent contract is established, a contract account corresponding to the intelligent contract appears on the block chain, and the block chain has a specific address; for example, "0 x68e12cf284 …" in each node in fig. 3a represents the address of the created contract account; the contract Code (Code) and account store (Storage) will be maintained in the account store for that contract account. The behavior of an intelligent contract is controlled by contract code, while the account storage of the intelligent contract preserves the state of the contract. At the same time, the Data field containing the transaction that created the smart contract holds the byte code for the smart contract. A bytecode consists of a series of bytes, each of which can identify an operation. Based on the multiple considerations of development efficiency, readability and the like, a developer can select a high-level language to write intelligent contract codes instead of directly writing byte codes. For example: the high-level language may employ a language such as Solidity, Serpent, LLL, and the like. For intelligent contract code written in a high-level language, the intelligent contract code can be compiled by a compiler to generate byte codes which can be deployed on a blockchain. Taking the Solidity language as an example, the contract code written by it is very similar to a Class (Class) in the object-oriented programming language, and various members including state variables, functions, function modifiers, events, etc. can be declared in one contract. Wherein the state variable is a value permanently stored in an account storage field of the smart contract for saving the state of the contract.

As shown in fig. 3b, after Bob sends a call transaction including call intelligent contract information to the blockchain system, each node device may execute the transaction in the mounted virtual machine. In fig. 3b, the From field of the transaction is used To record the address of the account initiating the invocation of the smart contract, the To field is used To record the address of the invoked smart contract, and the Data field of the transaction is used To record the method and parameters of the invocation of the smart contract. After invoking the smart contract, the account status of the contract account may change. Subsequently, a client may view the account status of the contract account through the accessed block link point (e.g., node 1 in fig. 3 b). The intelligent contract can be independently executed at each node in the blockchain network in a specified mode, and all execution records and data are stored on the blockchain, so that after the transaction is executed, transaction certificates which cannot be tampered and lost are stored on the blockchain. The usage status change notification and the environment data may be stored in a corresponding contract account as an account status through the data deposit transaction.

And S207, the early warning platform responds to the abnormal checking request aiming at the article to be checked to generate an abnormal checking result aiming at the article to be checked.

The abnormal verification request can be initiated by a user actively or initiated by the early warning system actively according to a preset abnormal verification request generation condition, and after the early warning platform receives the abnormal verification request, the abnormal verification request can be sent to the block chain system. According to the timestamp included in the usage state change notification and the environmental data, the early warning platform may set the preset abnormal verification request generation condition that the timestamp of the last received usage state change notification exceeds a preset time range compared with the timestamp of the last received environmental data, or set the time interval to be preset verification duration, initiate the abnormal verification request for a preset article in the warehouse, and the like, which is not limited in this specification.

For example, as described above, the exception checking result may be generated by cross-checking the usage state change notification corresponding to the identification information included in the exception checking request with the environment data of the warehouse, for example: when the abnormal checking request includes the identification information of the article a in the warehouse, the blockchain system may query, for the identification information, that the usage state change notification of the article a is cross checked with the environmental data of the warehouse, and if the usage state of the article a is changed to use only in the time stamp T1 and the environmental data in the preset time duration range does not exist in the blockchain system with the time stamp T1, obtain a corresponding abnormal checking result and execute S208, where the abnormal checking result may describe that the usage state of the article to be verified is use but the environmental data does not detect a user; or assuming that the use state of the article a is changed to use only by the timestamp T1, and there exists environmental data within a preset time range with the timestamp T1 in the blockchain system, if the environmental data indicates that the user does not have the right to use the article a, obtaining a corresponding abnormal verification result and performing S208, where the abnormal verification result may describe that the detected user does not obtain the usage authorization for the article to be verified.

The device that performs the cross check and generates the exception check result may vary according to actual requirements.

In an embodiment, the blockchain system invokes a data verification contract indicated by the data verification transaction according to the received data verification transaction, so that the data verification contract performs cross verification on the usage state change notification of the stored article to be verified and the environmental data of the warehouse, and generates the abnormal verification result. For example, as described above, according to the difference of the blockchain system structure, the initiator of the data verification transaction is the BaaS platform that receives the abnormal verification request, or the early warning platform itself.

In another embodiment, the cross-check is performed by the pre-warning platform instead of the blockchain system. The blockchain system can inquire the stored state change notice of the to-be-verified article and the environment data of the warehouse according to the received data inquiry transaction, and after the early warning platform acquires the use state change notice and the environment data inquired by the blockchain system, the blockchain system performs cross check on the use state change notice and the environment data to generate the abnormal checking result. The data query transaction is similar to the data verification transaction, and may correspond to different initiators according to different blockchain system structures, which is not described herein again.

And S208, the early warning platform triggers early warning according to the abnormal checking result.

When the early warning platform determines that the abnormal verification result meets the condition that the use state of the article to be verified is use, but the environmental data does not detect a user, or the detected user does not obtain the use authorization of the article to be verified, the early warning platform can trigger early warning operation. The early warning platform can give an alarm to a related person in charge according to a predefined contact way, or control early warning equipment in the warehouse to execute early warning operation.

Fig. 4 is a flowchart illustrating a warehouse management method based on a block chain according to an exemplary embodiment of the present disclosure. As shown in fig. 4, the method is applied to an early warning platform, and the method includes the following steps:

s401, receiving a use state change notification from a tag reader and environmental data of an environmental monitoring sensor, and storing the use state change notification and the environmental data into a block chain system; the system comprises a tag reader, an environment monitoring sensor and a block chain system, wherein the tag reader is used for reading an electronic tag corresponding to an article stored in a warehouse under the condition that the use state of the article changes, the environment monitoring sensor is used for acquiring environment data of the warehouse, and the block chain system is used for storing a use state change notice submitted by an early warning platform and the environment data;
