[0025] Embodiment one

[0026] Figure 1 is a flowchart of a blockchain-based power material detection method according to Embodiment One. The embodiment can be applied to the case of safe detection of power materials. The method can be executed by a blockchain-based power material detection device, which can be implemented in the form of hardware and / or software and can be integrated into an electronic device running the system.

[0027] As shown in Figure 1 , the method comprises:

[0028] S110, in response to receiving a power material detection task, determining, by a warehouse node, a to-be-detected power material from a power material warehouse according to the power material detection task.

[0029] The power material detection task is completed by the cooperation of the warehouse node, the transportation node and the detection node. Optionally, the warehouse node, the transportation node and the detection node are block nodes in the same blockchain network. The warehouse node is used to store power materials, the transportation node is used to transport power materials, and the detection node is used to detect the safety of power materials. Specifically, the to-be-detected power material is determined by the warehouse node, and the to-be-detected power material is transported to the detection node by the transportation node. The safety of the to-be-detected power material is detected by the detection node. The to-be-detected power material is a power material that needs to be detected.

[0030] The power material detection task can determine the to-be-detected power material and the detection completion time of the to-be-detected power material. The power material detection task is determined according to actual business needs, which is not limited here.

[0031] Optionally, the power material detection system publishes the power material detection task to the blockchain network in which the warehouse node, the transportation node and the detection node are located.

[0032] The warehouse node determines the to-be-detected power material from the power material warehouse according to the power material detection task in response to receiving the power material detection task.

[0033] S120, generating, by the warehouse node, a power material transportation request for the to-be-detected power material, and sending the power material transportation request to the blockchain network to trigger the smart contract in the blockchain network by the transportation node in the blockchain network.

[0034] The power material transportation request is used to request the transportation node to transport the to-be-detected power material. The transportation node in the blockchain network triggers the smart contract in the blockchain network in response to the power material transportation request to determine the transportation destination of the to-be-detected power material.

[0035] The smart contract is specifically a pre-designed, logically complete program or protocol that can be automatically triggered and executed. The smart contract includes the rights and obligations that can be exercised by the user. The smart contract, also known as chaincode, is an extension and upgrade of the traditional smart contract concept. It supports multiple high-level programming languages for writing internal business logic, including mainstream Java, Golang, and Node.js. According to different specific functions, chaincode is divided into two categories: system chaincode, which is used to process various internal events in the blockchain network system; and user chaincode, which is an open callable interface and program for the outside world, and is a unified encapsulation and centralized embodiment of business logic in specific practical application scenarios. The client node can only interact with the blockchain distributed ledger through the user chaincode, and can complete functions such as uploading and retrieving manufacturing data.

[0036] Optionally, the smart contract of the embodiment of the application encapsulates a game interaction method suitable for the power material detection process. Based on the smart contract in the embodiment of the application, the transfer destination of the power material to be detected is determined. The transfer destination is a detection node that performs security detection on the power material to be detected.

[0037] In response to the smart contract being triggered, the detection nodes in the blockchain network perform a detection strategy game to determine a target detection strategy for the power material to be detected.

[0038] In response to the smart contract being triggered, the detection nodes in the blockchain network perform a detection strategy game to determine a target detection strategy for the power material to be detected. The target detection strategy is used to determine a detection node that performs security detection on the power material to be detected. Optionally, the storage node, the transportation node, and the detection node store the locally collected and processed data, such as the power material to be detected data, and the target detection strategy to the blockchain network.

[0039] In one optional embodiment, in response to the smart contract being triggered, the detection nodes in the blockchain network perform a detection strategy game to determine a target detection strategy for the power material to be detected, including: in response to the smart contract being triggered, determining a current detection process of the power material to be detected; based on the detection node belonging to the process and the current detection process, selecting a detection node belonging to a next detection process from the detection nodes of the blockchain network to perform a detection strategy game to determine the target detection strategy for the power material to be detected.

[0040] It can be known that the safety detection of electric power materials generally includes multiple detection procedures. Only after all detection procedures are completed, the safety detection of electric power materials is considered to be completed. Optionally, there is a logical sequence between different detection procedures. For example, in the case that the detection procedures of electric power materials include detection procedure 1 and detection procedure 2, detection procedure 1 is a detection procedure before detection procedure 2, and electric power materials can only proceed to detection procedure 2 after detection procedure 1. Optionally, different detection procedures are completed by different detection nodes. Each detection procedure includes at least two detection nodes, that is, at least two detection nodes can complete the safety detection task of the detection procedure. The circulation of electric power materials between different detection procedures also needs to be completed by a transportation node. Optionally, after the detection node belonging to the current detection procedure completes the safety detection of the to-be-detected electric power materials, an electric power material transfer request is generated for the to-be-detected electric power materials, and the electric power material transfer request is sent to the blockchain network, so that the transportation node in the blockchain network triggers the smart contract in the blockchain network. Among them, the current detection procedure refers to the detection procedure in which the to-be-detected electric power materials are currently located.

[0041] In response to the smart contract in the blockchain network being triggered, the current detection procedure of the to-be-detected electric power materials is determined. Based on the detection node belonging to the procedure and the current detection procedure, the detection node belonging to the next detection procedure is selected from the detection node in the blockchain network, the detection strategy game is performed, and the target detection strategy for the to-be-detected electric power materials is determined. The detection strategy game based on the detection node belonging to the next detection procedure is actually to determine the detection node for the to-be-detected electric power materials to perform the next detection procedure from the detection nodes that can perform the next detection procedure.

[0042] If the safety detection of electric power materials includes multiple detection procedures with a logical sequence, after the target detection strategy for the to-be-detected electric power materials is determined, the determination operation of the current detection procedure is returned to be executed until the current detection procedure is the final detection procedure, and then it is determined that the to-be-detected electric power materials are detected. Optionally, the to-be-detected electric power materials that have completed the detection are transferred back to the storage node by the transportation node. The above technical solution can be applied to the case that the safety detection of electric power materials includes multiple detection procedures with a logical sequence. According to the logical sequence between the detection procedures, the detection strategy game is performed by the detection nodes responsible for the same detection procedure, the target detection strategy for the to-be-detected electric power materials is determined, and the detection efficiency of electric power materials is improved.

[0043] The technical scheme of the embodiment of the application determines the power material to be detected through the warehouse node, generates a power material transfer request, and notifies the transportation node to trigger the smart contract in the blockchain network, so that the detection node in the blockchain network responds to the triggering of the smart contract to perform detection strategy game, and determines the target detection strategy for the power material to be detected, thereby improving the automation level of power material detection. From determining the power material to be detected, transferring the power material to the detection power material, the whole process of power material detection does not need manual intervention, and the detection efficiency of the power material is effectively improved. The embodiment of the application applies the blockchain technology to the detection of the power material, and guarantees the data security of the power material.

[0044] In an optional embodiment, the method further includes: a block node in the blockchain network performs disturbance detection on a local running environment in response to the smart contract being triggered; wherein the block node includes: a warehouse node, a transportation node, and a detection node; in a case where it is detected that there is disturbance in the local running environment, a disturbance type is determined, and the disturbance is processed based on the disturbance type.

[0045] The block node in the blockchain network performs disturbance detection on a local running environment in response to the smart contract being triggered, and detects whether there is disturbance in the local running environment. Wherein, the disturbance will affect the detection strategy game between the detection nodes. Therefore, in a case where the block node detects that there is disturbance in the local running environment, the disturbance type is determined. Optionally, the disturbance type includes explicit disturbance and implicit disturbance. Compared with the implicit disturbance, the explicit disturbance has a greater impact on the detection strategy game between the detection nodes, and the explicit disturbance directly affects the detection strategy game. Exemplarily, the display disturbance includes: detection device failure or emergency detection instruction insertion. The implicit disturbance can be detection cumulative delay, and the implicit disturbance does not directly affect the detection strategy game. The influence of the implicit disturbance on the detection strategy game is indirect and limited. The implicit disturbance will also have a significant impact on the detection strategy game after a period of accumulation.

[0046] The local running environment of the block node such as the warehouse node, the transportation node, and the detection node in the blockchain network may have disturbance. In a case where the running environment of the block node has disturbance, the block node needs to process the disturbance according to the disturbance type. Optionally, the block node excludes explicit disturbance, monitors implicit disturbance, and repairs the implicit disturbance in a case where the block node is in an idle state. Optionally, in a case where the disturbance is excluded, the detection strategy game is performed through the detection node, and the target detection strategy is determined for the power material to be detected.

[0047] The technical scheme, in the disturbance detection of the local running environment, in the case that the disturbance is detected in the local running environment, the disturbance type is determined, and the disturbance is processed based on the disturbance type, so as to provide a stable running environment for subsequent detection node detection strategy game, and the accuracy of the target detection strategy is ensured.

[0048] In an optional embodiment, after the detection node in the blockchain network performs the detection strategy game to determine the target detection strategy for the power material to be detected in response to the smart contract being triggered, the method further includes: determining a target detection node in the detection node of the blockchain network based on the target detection strategy; transferring the power material to be detected from the power material storage to the material detection equipment corresponding to the target detection node by the transportation node control material transfer equipment; and detecting the power material to be detected by the target detection node control material detection equipment.

[0049] The target detection strategy is used to determine the detection node for the safe detection of the power material to be detected in the detection node of the blockchain network. The target detection node is the detection node for the safe detection of the power material to be detected.

[0050] The power material detection system determines the target detection node in the detection node of the blockchain network based on the target detection strategy. The determination of the target detection node is equivalent to the determination of the transfer destination of the power material to be detected.

[0051] The power material detection system transfers the power material to be detected from the power material storage to the material detection equipment corresponding to the target detection node by the transportation node control material transfer equipment, and detects the power material to be detected by the target detection node control material detection equipment. The material transfer equipment corresponds to the transportation node in the blockchain network, and the material transfer equipment is used for transferring the power material. The material detection equipment corresponds to the detection node in the blockchain network, and the material detection equipment is used for the safe detection of the power material.

[0052] The technical scheme, in the disturbance detection of the local running environment, in the case that the disturbance is detected in the local running environment, the disturbance type is determined, and the disturbance is processed based on the disturbance type, so as to provide a stable running environment for subsequent detection node detection strategy game, and the accuracy of the target detection strategy is ensured.

[0053] Embodiment two

[0054] Figure 2is a flowchart of a blockchain-based power material detection method according to embodiment two. This embodiment is further optimized on the basis of the above-mentioned embodiment, and specifically, the operation "in response to the smart contract being triggered, the detection nodes in the blockchain network perform a detection strategy game to determine a target detection strategy for the power material to be detected" is refined.

[0055] As shown in Figure 2 , the method comprises:

[0056] S210, in response to receiving a power material detection task, determining, by a warehouse node, power material to be detected from a power material warehouse according to the power material detection task.

[0057] S220, generating, by the warehouse node, a power material transfer request for the power material to be detected, and sending the power material transfer request to a blockchain network to make a transport node in the blockchain network trigger a smart contract in the blockchain network.

[0058] S230, in response to the smart contract being triggered, determining a game role of a detection node in the blockchain network based on a local detection resource of the detection node.

[0059] Wherein, the local detection resource is used to determine the performance bottleneck of the detection node. The game role refers to the role of the detection node in the detection strategy game. The game role is used to determine the status of the detection node in the detection strategy game. Optionally, the game role includes a leader node and a follower node. Optionally, the detection node that reaches the performance bottleneck is determined as the leader node. The detection node participating in the detection strategy game except the leader node is determined as the follower node.

[0060] Wherein, the smart contract encapsulates a game interaction method adapted to the power material detection process. When the smart contract is triggered, the detection nodes in the blockchain network that meet the game conditions determine the role of the detection node in the detection strategy game based on the local detection resource of the detection node.

[0061] S240, performing, by the detection node, a detection strategy game based on the game role and using the local detection resource to determine the target detection strategy for the power material to be detected.

[0062] The detection nodes participating in the detection strategy game perform the detection strategy game based on their respective game roles and using the local detection resource to determine the target detection strategy for the power material to be detected. Optionally, the detection strategy game performed by the detection node is a non-cooperative subgame.

[0063] In an optional embodiment, the game roles include a leading node and a following node; accordingly, the method for determining the target detection strategy for the power material to be detected based on the game roles by the detection node using the local detection resource includes: determining the material detection strategy of the leading node as an initial detection strategy; generating a reference detection strategy based on the initial detection strategy by the following node; adjusting the initial detection strategy based on the reference detection strategy by the leading node to obtain a new detection strategy, and determining whether the new detection strategy meets a preset equilibrium condition; and determining the new detection strategy meeting the preset equilibrium condition as the target detection strategy.

[0064] The leading node is an organizer of the detection strategy game, and the following node is a participant of the detection strategy game. The position of the leading node in the detection strategy game is higher than that of the following node. The preset equilibrium condition is used to measure whether the detection strategy game reaches equilibrium. The preset equilibrium condition is determined according to actual business requirements, which is not limited here. For example, the preset equilibrium condition can be Nash equilibrium.

[0065] The initial detection strategy is provided by the leading node, and the reference detection strategy is provided by the following node based on the initial detection strategy. The reference detection strategy is used to adjust the initial detection strategy. Specifically, the leading node first provides a material detection strategy, the following node generates a reference detection strategy based on the initial detection strategy of the leading node, the leading node adjusts the initial detection strategy based on the reference detection strategy to obtain a new detection strategy, and determines whether the new detection strategy meets a preset equilibrium condition. The new detection strategy meeting the preset equilibrium condition is determined as the target detection strategy. It can be understood that the new detection strategy is more efficient than the initial detection strategy. The above technical solution guarantees the effectiveness of the target detection strategy, and provides data support for improving the detection efficiency of the power material.

[0066] In an optional embodiment, adjusting the initial detection strategy based on the reference detection strategy by the leading node to obtain a new detection strategy includes: determining strategy evaluation parameters of the initial detection strategy and the reference detection strategy, respectively; adjusting the initial detection strategy based on the strategy evaluation parameters by the leading node to obtain the new detection strategy; wherein the strategy evaluation parameters include at least one of detection time length, equipment idle rate, and detection energy consumption.

[0067] The policy evaluation parameter is used to measure the effectiveness of the detection policy. Specifically, the effectiveness of the reference detection policy and the initial detection policy. The policy evaluation parameter includes at least one of the detection duration, the equipment idle rate, and the detection energy consumption. The detection duration refers to the time required for the detection node to perform safety detection on the power material to be detected. The equipment idle rate refers to the idle rate of the material detection equipment corresponding to the detection node. The detection energy consumption refers to the energy consumed by the detection node to perform safety detection on the power material to be detected.

[0068] The leader node adjusts the initial detection policy based on the policy evaluation parameter to obtain a new detection policy. Optionally, the leader node adjusts the initial detection policy to obtain a new detection policy with the adjustment target of shortening the detection duration, reducing the equipment idle rate, and reducing the detection energy consumption, so that the new detection policy is more effective than the initial detection policy. The above technical solution adjusts the initial detection policy based on the policy evaluation parameter to obtain a new detection policy, which is beneficial to guarantee the effectiveness of the target detection policy and provides data support for improving the detection efficiency of power materials.

[0069] In a specific embodiment, a game interaction model adapted to the power material detection process is encapsulated in the smart contract of the blockchain network. Optionally, the game interaction model is a Stackelberg game model.

[0070] The game interaction model can be described as: {O1, O2,..., O i ,...,O n} represents n power materials to be detected, and {M1, M2,..., M i ,...,M m} represents m detection nodes that can perform safety detection. The power material to be detected O i contains n j detection procedures. M i,j ∈{1,2,...,M} represents the set of detection nodes available for the jth detection procedure of the power material to be detected O i . If the detection equipment M k ∈M i,j is selected to perform the jth detection procedure of the power material O i , the required detection time is t i,j,k .

[0071] The game interaction model is a two-layer game interaction model with one leader node at the upper layer and multiple follower nodes at the lower layer. Optionally, the detection node reaching the performance bottleneck is determined as the leader node. The detection nodes participating in the game of detection strategies other than the leader node are determined as the follower nodes. In each game interaction model, three elements are defined, i.e., the participating nodes, the detection strategies and the utility functions. Let M1, S1 and U1 represent the leader node, its detection strategy and utility function, respectively. Let M f , S f and U f represent the follower nodes and their detection strategies and utility functions, respectively.

[0072] The game interaction model of the leader node can be defined as a three-tuple:

[0073] G=((M1,M f ),(S1,S f ),(U1,U f ))

[0074] The utility function corresponds to the three optimization objectives in the coordination control model: the detection time length, the device idle rate and the detection energy consumption. The three optimization objectives mean that the tasks are distributed to each detection node as much as possible while consuming less time and lower energy.

[0075] The utility function is defined as follows:

[0076] MinU k =[CM k ,ε k ,E k ] T

[0077] s.t.C i,j ≥0,C i,j -C i,j-1 ≥t i,j,k *x i,j,k ,i=1,2,...,n;j=2,...,

[0078]

[0079] k∈[1,m],t∈[1,T k -1]

[0080] s.t represents the constraint condition, the constraint condition in the first row guarantees the logical sequence before and after different detection processes, and the jth detection process needs to be performed on the to-be-detected electric power resources O i before the (j-1)th detection process. i is the label of the to-be-detected electric power resources, and j is the label of the detection process. C i,j represents the to-be-detected electric power resources O iThe detection completion time of the jth detection process. i,j,k is a binary decision variable. The constraint in the second row ensures that each power material O i will only be assigned to one material detection device T k , and T k detection nodes participate in the strategy game, and t is the label of the material detection device corresponding to the detection node. The last constraint in the second row is used to ensure that the start time of the next detection task performed by the material detection device corresponding to the detection node must be after the completion of the current detection task.

[0081] In the process of game interaction, first, the leader node M1 provides the initial detection strategy, and then the follower node M f According to the initial detection strategy s1 of M1, a non-cooperative sub-game is played, and a reference detection strategy is generated, which constitutes a reference detection strategy set:

[0082]

[0083] Then, feedback to M1 for the next iteration until formula (4) (5) is satisfied, and the equilibrium solution of the game is s * = (s1 * , s f * )

[0084]

[0085]

[0086] where,

[0087] represents the decision-making process of the follower node according to the initial detection strategy of the leader node. The whole process is that the leader node makes the initial detection strategy first, and after the leader node makes the decision, the follower node makes the decision to generate the reference detection strategy according to the initial detection strategy of the leader node. Then the leader node adjusts the initial detection strategy according to the decision of the follower node, and so on, until the Nash equilibrium is reached. It is worth noting that in all formulas, the detection strategy with an asterisk represents the adjusted detection strategy, which means that the utility function of the leader node 1 is more efficient after adjusting S1.

[0088] which means that the utility function of the i-th follower node is more efficient after adjusting its original detection strategy.

[0089] which means Except for the i-th slave node, other slave nodes receive the initial detection strategy of the leader node to make a decision process.

[0090] In one specific embodiment, Figure 3 is a structural schematic diagram of a blockchain-based power material detection system provided according to an embodiment.

[0091] Referring to Figure 3 , the blockchain-based power material detection system includes power material detection resources, a blockchain detection unit, a blockchain network, and a smart contract. Among them, the power material detection resources mainly include three categories, namely, storage equipment, transfer equipment, and detection equipment. Through the application of multi-detection unit autonomous technology, the three categories of resources are installed with industrial computers that can record their own state and issue instructions, and then organized through the running mode of the multi-detection unit autonomous system. The storage equipment installed with the industrial computer can serve as a block node in the blockchain network, that is, the block unit for storage equipment in Figure 3 . The block unit for storage equipment corresponds to the storage node of the embodiment. The transfer equipment installed with the industrial computer can serve as a block node in the blockchain network, that is, the block unit for transfer equipment in Figure 3 . The block unit for transfer equipment corresponds to the transfer node of the embodiment. The detection equipment installed with the industrial computer can serve as a block node in the blockchain network, that is, the block unit for detection equipment in Figure 3 . The block unit for detection equipment corresponds to the detection node of the embodiment. It is worth noting that Figure 3 the transfer equipment and the detection equipment in correspond to the material transfer equipment and the material detection equipment in the above embodiment, respectively.

[0093] Figure 4 is a structural schematic diagram of a blockchain-based power material detection device provided by the third embodiment of the present application. The embodiment can be applicable to the case of safe detection of power materials. The device can be realized by software and / or hardware, and can be integrated into an electronic device such as a smart terminal.

[0094] As shown in Figure 4 , the device can include a to-be-detected power material determination module 410, a power material transfer request sending module 420, and a target detection strategy determination module 430.

[0095] The to-be-detected power material determination module 410 is configured to, in response to receiving a power material detection task, determine, by a storage node, to-be-detected power materials from power material storage according to the power material detection task;
