Referring to fig. 2, fig. 2 is a flowchart illustrating a task demand response method based on a block chain according to a first embodiment of the present invention.
In this embodiment, the block chain-based task demand response method includes:
step S10, receiving a task participating in demand response based on a preset block chain, and acquiring an evaluation index of the task;
in this embodiment, an architecture of a blockchain system is constructed based on the related art of blockchains, and a preset blockchain is constructed based on the architecture. Specifically, the preset block chain is constructed in a decentralized manner, and the preset block chain can be controlled by a plurality of mechanism centers, that is, the preset block chain is controlled by each entity node. The nodes coordinate to work according to a consensus mechanism so as to jointly maintain the whole preset block chain. The chain of preset blocks may be a continuous increase of participants, i.e. a continuous increase of nodes for applications, devices, organizations, etc. or a connection of applications, devices, organizations, etc. to nodes. After the preliminary construction of the preset block chain is completed, the tasks participating in the demand response are received based on the preset block chain, and the evaluation indexes of the tasks are obtained so as to determine the types of the tasks based on the evaluation indexes.
It should be noted that the task participating in the demand response is generated by nodes such as applications, devices, and organizations in the preset block chain or applications, devices, and organizations connected to the nodes. Certainly, the task participating in the demand response may also be generated by an external application and acquired by a preset block chain.
In an embodiment, the evaluation index is task type information participating in the demand response, for example, the tasks include storage, energy consumption, communication, bandwidth, time, flow and other indexes, each task may have the above indexes, and the tasks may select or establish corresponding indexes according to their own services and demands to meet different service demands. Certainly, the task may select one or more indexes according to its own service requirements, that is, different evaluation indexes are connected to different service requirements. In other embodiments, the evaluation index may also include other indexes, or more or less evaluation indexes, and is not limited herein.
In an embodiment, different index nodes are set in a preset block chain, and data safety is ensured, so that the reliability of task demand data is realized according to different task demands. The index node is used for processing functions of corresponding indexes, such as storing data, transmitting data and the like. In addition, the data interaction between the nodes is verified through a digital signature technology, mutual trust is not needed, the data interaction is only carried out according to the established rule of the preset block chain, and the nodes cannot cheat each other, so that the data security can be ensured. Meanwhile, because the nodes are distrusted, public identity is not required between the nodes, each participated node is anonymous, the current node cannot tamper with other nodes, and data interaction between the nodes can be traced, so that data security can be ensured.
To facilitate understanding of the architecture of the blockchain system, reference is made to fig. 3, and fig. 3 is a schematic diagram of the blockchain architecture according to the embodiment of the present invention, in which smart driving, smart medicine, research institution, load aggregation, smart home, and service company are connected to the blockchain, and the nodes are synchronized to obtain the synchronized blocks. The block chain system structure is controlled by a plurality of organizations (such as intelligent driving, intelligent medical treatment, research organization, load aggregation, intelligent home, service company), the block chain supports point-to-point transaction of massive application demands, information among nodes is public and transparent, and decentralized distributed systems are formed by means of distributed accounting, spreading and the like. Due to the difference of the task requirements of each mechanism, different requirements are required for privacy, safety, supervision and the like of data, and by constructing the system structure, the various requirements can be met, the overall data processing speed in the block chain is improved, more interactive information can be processed in a short time, and therefore the data safety can be ensured, and the processing capacity of a single node in the block chain is improved.
Step S20, selecting a target block from each block of the preset block chain based on the evaluation index;
when the preset block chain is divided into blocks, a plurality of different evaluation indexes, such as storage, energy consumption, communication, bandwidth, time, flow and other indexes, can be set first, and then the occupation ratio of the evaluation indexes in each task requirement is calculated respectively. Since each evaluation index has different properties, usually has different dimensions and magnitude, when the level difference between the evaluation indexes is large, if the original ratio is directly used for analysis, the classification processing will not be accurate enough, and therefore, in order to ensure the reliability of the result, the ratio needs to be standardized, and the standardization processing can be realized by a data standardization algorithm, for example, an extreme value method, a standard deviation method, a three-fold line method, a semi-normal distribution method, and the like, and will not be described herein again. Then, based on the percentage of the normalization process, similarity distances between the tasks are calculated for different indices, for example, euclidean distances, L1 norms, and the like, but not limited thereto. And finally, classifying each task based on the similarity distance, and dividing the blocks of the preset block chain based on the classified blocks. After the classification, a corresponding target block can be selected for a task newly received by the preset block chain. Specifically, based on the task evaluation index, a target block is selected from each block of the preset block chain.
It should be noted that each task has a unique identifier, such as an Identity (ID), and after the target block is selected for the task, the unique identifier and the task can be delivered to the target block together, so that the target block can accurately and quickly process the task.
In addition, it should be noted that, the blocks of the preset block chain are connected to each other, the nodes, tasks, indexes, and the like in the blocks are connected to each other, and based on a consensus mechanism, the nodes or the blocks may share respective messages.
In one embodiment, the target blocks to be connected are determined according to the priority of the evaluation index, and the target blocks can be one or more. Specifically, referring to fig. 4, fig. 4 is a schematic diagram illustrating a connection of block chain blocks according to an embodiment of the present invention, where priorities of storage indexes and bandwidth indexes in related tasks of smart medicine are higher, and therefore two block chain node services are respectively selected as target blocks. The processing procedures of other mechanisms or applications in the figure are basically the same as those of the smart medical treatment, and are not described in detail here. In other embodiments, the target area to be connected may be determined according to factors such as the weight, importance, and ratio of the evaluation index.
Specifically, step S20 includes:
a step a21 of standardizing the evaluation indexes to obtain standardized evaluation indexes;
a22, performing weighting operation on the plurality of standardized evaluation indexes to obtain weights of the plurality of evaluation indexes;
step a23, selecting a target block from the blocks of the preset block chain based on the weight.
After the evaluation indexes of the tasks are obtained, the multiple evaluation indexes are subjected to standardization processing based on a data standardization algorithm, then the multiple evaluation indexes subjected to standardization processing are subjected to weighting operation to obtain the weights of the multiple evaluation indexes, and finally, a target block is selected from all blocks of a preset block chain based on the weights. Wherein the evaluation index includes a plurality of indexes.
It should be noted that, since each evaluation index has different properties, usually has different dimensions and orders of magnitude, when the levels of the evaluation indexes are greatly different, if the original evaluation index is directly used for analysis, the evaluation indexes will not have comparability, and therefore, in order to ensure the reliability of the result, each evaluation index needs to be standardized to eliminate the property difference (dimension difference) of each evaluation index.
The data normalization algorithm may be an extreme value method, a standard deviation method, a three-fold line method, a semi-normal distribution method, or the like. The weighting operation may be a mean square error operation method, or may be other methods for calculating the weight.
In an embodiment, the block corresponding to the index with the largest weight can be selected as the target block, so that the demand response speed corresponding to the index with the largest weight is higher, and the interaction efficiency is higher. In other embodiments, the blocks corresponding to the indexes with weights greater than the preset weight threshold may be selected as the target blocks, in which case, the target blocks may include one or more blocks, and the preset weight threshold may be set according to actual needs, which is not limited herein.
And step S30, allocating the task to the target block for processing.
And after the target block is selected and obtained, distributing the task to the target block for processing. Specifically, the processing is performed by the block link node service in the target block, that is, the response processing is performed by the service node having the corresponding demand response. It should be noted that the task is allocated to the target block and is accompanied by a unique identifier of the task, so that the target block can index the task based on the unique identifier, thereby improving the response speed of the task demand.
In an embodiment, after the task is allocated to the target block, the task and the nodes in the target block form a chained storage network structure, the task and each node in the target block can share information, and based on a preset rule of a preset block chain, data security can be ensured and response speed of task requirements can be improved.
The embodiment of the invention provides a task demand response method based on a block chain, which is characterized in that a task participating in demand response is received based on a preset block chain, and an evaluation index of the task is obtained; selecting a target block from all blocks of a preset block chain based on the evaluation index; and allocating the task to the target block for processing. The embodiment of the invention is based on a decentralized preset block chain, so that interaction between data is carried out according to a set rule, specifically, data interaction between nodes is verified through a digital signature technology, mutual trust is not needed, mutual deception cannot be carried out between the nodes, and the nodes are distrusted so that identities do not need to be disclosed between the nodes, each participated node is anonymous, in addition, other nodes cannot be tampered by the current node, data interaction between the nodes can be traced, the reliability of the data under a task response requirement is ensured, and meanwhile, a corresponding target block is selected according to an evaluation index of a task, so that a task requirement can realize a faster response speed under the corresponding target block. Therefore, the embodiment of the invention improves the reliability of data and the response speed of task requirements.
Further, based on the first embodiment, a second embodiment of the block chain-based task demand response method according to the present invention is provided.
Referring to fig. 5, fig. 5 is a flowchart illustrating a task demand response method based on a block chain according to a second embodiment of the present invention.
In this embodiment, before the step S10, the method for responding to task demands based on block chains further includes:
step S40, dividing a preset blockchain into side chains corresponding to a plurality of preset evaluation indexes, where the number of the side chains is the same as the number of the plurality of evaluation indexes, and the side chains include nodes for processing tasks;
step S50, constructing a main chain in the preset block chain, and respectively connecting each side chain with the main chain, wherein the main chain includes a main node with a sharing function.
In this embodiment, the architecture of the main side chain is further designed based on the preset block chain, and the task may select or establish a corresponding index according to its own service and requirement, so as to implement different service requirements through the main side chain. Specifically, a preset block chain is divided into side chains corresponding to a plurality of preset evaluation indexes, wherein the number of the side chains is the same as that of the plurality of evaluation indexes, the side chains comprise nodes for processing tasks, then a main chain is constructed in the preset block chain, and the side chains are respectively connected with the main chain, wherein the main chain comprises a main node with a sharing function.
It should be noted that the main chain is used as a shared platform of all participants, that is, a shared data channel of all nodes such as applications, task requirements, devices, and organizations, and can implement trading and sharing among each evaluation index, block, and main chain. Specifically, referring to fig. 6, fig. 6 is a schematic diagram of a master side chain according to an embodiment of the present invention, in which a side chain of a bandwidth includes five nodes, and a side chain of a time includes five nodes, of course, the number of nodes of the side chain is set according to an actual situation, and is not limited here, while a main chain is used to connect the side chain of the bandwidth and the side chain of the time, and the main chain includes two master nodes, and the master nodes are used to implement sharing of data, and of course, the number of nodes of the main chain is set according to an actual situation, and is not limited.
In an embodiment, the preset evaluation index may include indexes such as storage, energy consumption, communication, bandwidth, time, and flow, and the task may select or establish a corresponding index according to its own service and requirement to meet different service requirements. Certainly, the task may select one or more indexes according to its own service requirements, that is, different evaluation indexes are connected to different service requirements. In other embodiments, the evaluation index may also include other indexes, or more or less evaluation indexes, and is not limited herein.
In the embodiment, the main side chain is designed according to the evaluation index, so that the interaction efficiency between tasks with the same evaluation index is improved under the same side chain, and the subsequent data processing and linking are facilitated.
Further, based on the first embodiment, a third embodiment of the block chain-based task demand response method according to the present invention is provided.
In this embodiment, the block chain-based task demand response method further includes:
step A, when a request for adding an application into the preset block chain is detected, verifying whether the application has an adding authority or not;
and B, if the application has the adding permission, adding the application into the preset block chain so as to allow information interaction among a plurality of applications based on the preset block chain.
In this embodiment, the preset block chain is controlled by a plurality of mechanism centers, and the application can add the preset block chain only when acquiring the authority. For the preset block chain, when a request of an application for adding into the preset block chain is detected, whether the application has the adding authority is verified, and if the application has the adding authority, the application is added into the preset block chain. After the plurality of applications are added into the preset block chain, based on the established rule of the block chain, the plurality of applications carry out information interaction based on the preset block chain.
In addition, it should be noted that, the blocks of the preset block chain are connected with each other, the applications, nodes, tasks, indexes, etc. in the blocks are connected with each other, and each node may connect different applications, and based on a consensus mechanism, the applications may share respective messages. In addition, the nodes of the preset block chain are mutually synchronous, one node loses data, and other nodes also back up the data, so that the safety of the data can be ensured.
Specifically, in the step B, adding the application to the preset block chain includes:
step B1, obtaining the unique identifier of the application;
and step B2, connecting the application to a node in the preset block chain based on the unique identification.
In this embodiment, the application itself has a unique identifier, and for the preset block chain, the unique identifier of the application is acquired, and then the application is connected to a node in the preset block chain based on the unique identifier. Wherein, the unique identification can be ID identification.
It should be noted that each application has a unique identifier, such as an ID identifier, and when the application joins the preset block chain, the unique identifier and the application can be handed over to the preset block chain together, so that the preset block chain can accurately and quickly index and process the application.
In this embodiment, the permission verification is performed on the added application, so that the allowed application can be added to the preset block chain, thereby ensuring the reliability of the preset block chain.
Further, based on the first embodiment, a fourth embodiment of the block chain-based task demand response method according to the present invention is provided.
In this embodiment, the block chain-based task demand response method further includes:
step C, when the preset block link receives a plurality of tasks, similarity calculation is carried out on the tasks;
and D, connecting the task with the similarity value smaller than a preset similarity threshold value to the same block in the preset block chain based on the similarity calculation result.
In this embodiment, when the preset block chain receives a plurality of tasks, that is, when the preset block chain has a plurality of tasks, similarity calculation is performed on the plurality of tasks, and then, based on a result of the similarity calculation, the task with the calculated similarity smaller than the preset similarity threshold is connected to the same block in the preset block chain. It can be understood that the similarity calculation is performed on a plurality of tasks, that is, the types of the tasks are calculated, then the tasks are classified according to the types, and the classified tasks are respectively connected to the blocks. The preset similarity threshold is set according to actual needs, and is not limited herein, for example, when the euclidean distance is calculated, the preset similarity threshold is an absolute distance.
When tasks are classified, the size of the difference between the tasks needs to be calculated. The similarity calculation is to compare the similarity of two tasks, i.e. to calculate the feature value and the feature distance between the tasks, if the feature distance is small, the similarity is large, and if the feature distance is large, the similarity is small.
In one embodiment, the similarity calculation is performed based on evaluation indexes of tasks, and the evaluation indexes can include storage, energy consumption, communication, bandwidth, time, flow and other indexes. The similarity calculation may be performed by calculating a euclidean distance (euclidean distance), a manhattan distance, a minkowski distance, or the like. In other embodiments, the evaluation index may be set according to actual needs, and is not limited herein.
Specifically, in the step C, the performing similarity calculation on the plurality of tasks includes:
step C1 of calculating the ratios of the evaluation indexes of the plurality of tasks, respectively;
step C2, standardizing the ratio to obtain a standardized ratio;
and step C3, calculating Euclidean distances among the tasks based on the standardized occupation ratio, wherein the Euclidean distances are calculation results of the similarity.
In this embodiment, the occupation ratios of the evaluation indexes of the plurality of tasks are calculated, respectively, then, the occupation ratios are normalized based on a data normalization algorithm, and finally, the euclidean distances between the plurality of tasks are calculated based on the occupation ratios after the normalization, where the euclidean distances are the similarity calculation results. Of course, the duty ratio may also be replaced by a priority, weight, importance, etc.
It should be noted that, because each evaluation index has different properties, and usually has different dimensions and magnitudes, when the level difference between the evaluation indexes is large, if the original ratio is directly used for analysis, the subsequent classification processing will be inaccurate, and therefore, to ensure the reliability of the result, the ratio needs to be standardized, and the standardization processing can be implemented by a data standardization algorithm, for example, an extreme value method, a standard deviation method, a three-fold line method, a semi-normal distribution method, and the like, which is not described herein again.
And then, calculating Euclidean distances among the tasks according to different indexes based on the proportion of the standardized processing, classifying the tasks based on the Euclidean distances, and dividing blocks of a preset block chain based on the classified blocks. After the classification process is completed, a corresponding target block can be selected for a task newly received by the preset block chain. Specifically, based on the task evaluation index, a target block is selected from each block of the preset block chain.
In this embodiment, tasks of similar types are connected to the same block in the preset block chain, so that the interaction efficiency between similar tasks is higher, and the task response speed of the preset block chain is further improved.
