Detailed Description
The invention will be described in further detail with reference to the drawings and the specific examples.
The invention adopts the blockchain as a key technology of the agile control system, and the blockchain is a novel technical system combining a peer-to-peer network, distributed storage, an encryption algorithm, a consensus algorithm and a virtual machine technology. The typical blockchain system comprises a peer-to-peer network which is widely interconnected and intercommunicated by a plurality of computer nodes, and the nodes jointly determine which data are approved and recorded through encryption communication and a consensus mechanism; the approved data records form a front-back connected chain structure based on a hash algorithm, and distributed backups are stored in all nodes; by means of a code execution environment established by a virtual machine technology, intelligent contracts can be flexibly deployed in a blockchain system according to requirements to support various decentralised applications, and running data of the intelligent contracts also maintains traceable and tamper-resistant records in the system. From the practical effect, the block chain avoids the defects in the linearization and centralization traditional system architecture through proper design of the interrelation between the system flow and the network nodes, builds a safe, reliable, flexible, extensible, highly reliable and well-adaptive distributed application execution environment, and well responds to various requirements of the agile control information system. Therefore, the invention creatively combines the agile command system with the blockchain technology, firstly innovatively designs the composition framework of the agile command system, and combines the characteristics of the agile command system to further improve and perfect the traditional blockchain technology so as to meet the actual requirements of the agile command system.
As shown in fig. 1, the agile chain-based finger control system of the present invention includes:
the information resource node is a basic supporting node for establishing a block chain-based agile control system and is used as a main calculation, storage and communication carrier for the operation of the agile control-oriented block chain system, and other nodes are connected into the system by establishing a connection relation with the information resource node;
the command control node is used as a main body for implementing the command control function, and is connected with the information resource and the execution terminal to open the information flow and the command flow after being connected with the system;
the task terminal node is used as a carrier for executing each task, and particularly comprises various equipment with data processing and communication capabilities and the like; and the task terminal node is accessed into the agile control block chain system through the information resource node.
All nodes added into the system realize identification of the identity and management and control of various authorities based on the digital identity certificate.
According to technical characteristics and functional positioning of different main bodies in agile finger control activities, each participating node of the system can be divided into three main categories, namely an information resource node, a command control node and a task terminal node. The nodes are widely interconnected in a peer-to-peer network at the physical level, as shown in fig. 1.
In a specific application example, the information resource node is generally established by a host which has higher reliability and reliability, higher operation and storage performance and can run for a long time; by writing the operation logic of the agile index control blockchain system into the information resource node, the information resource node mainly realizes the following functions: 1) Providing sufficient computing resources for system operation and smart contract execution. 2) And stable and efficient storage and reading services are provided for various data of the system. 3) And the system maintains a durable and rapid network connection and communication with the rest of the nodes.
In a specific application example, the task terminal node realizes the following functions under intelligent contract regulation and control in the processes of command control and task execution: 1) And reporting the key information such as the respective space position, running state, environment information and the like in real time. 2) And receiving the scheduling and control instructions of the node users with the corresponding authorities. 3) And requesting to call the information resource according to the command information and the authority intelligent contract strategy.
In a specific application example, the command control node realizes the following functions under intelligent contract regulation: 1) Information resources such as information data and processing calculation power are called. 2) And issuing command control instructions to the task execution unit and the execution equipment. 3) And coordinating the relationship with other command control nodes.
In a specific application example, the invention can refer to a public key infrastructure (Public Key Infrastructure, PKI) system, so that each node added into the system can realize identification of identity and management and control of various authorities based on digital identity certificates.
In a specific application example, in the system operation, besides the information resource node needs to be kept on-line stably, the command control and task terminal node can join or leave the blockchain network as required.
In a specific application example, when a plurality of nodes aim at specific task requirements, a special data communication connection can be established as a task channel. When a task needs to be executed, the related node determines an encryption method, a consensus rule and the like according to a task contract, establishes a task channel, and maintains corresponding task data, as shown in fig. 2.
Furthermore, the mechanism of the task channel can realize the autonomous definition of the task and the on-demand call of each node, thereby ensuring the flexibility of the system function and the confidentiality of the task information.
Based on the task channel, in a preferred embodiment, the invention further comprises an intelligent contract unit, wherein the intelligent contract unit is a main carrier for executing on-chain application and function realization, and the agile command service mainly surrounds three core links of task contract establishment, task channel establishment and task execution. Wherein:
task contract programming: the task in the agile control concept refers to a series of target states and corresponding actions to be taken by each participant. The task contract is the standardized setting of contents such as task connotation, participators, operation rules and the like in the blockchain system, and is usually compiled by a command control node with authority.
In particular embodiments, a typical task contract includes the following: 1) Task number [ task_id ]; 2) Task content [ task_content ]: the object, time, target state, execution region and the like of the task are defined; 3) Task rule [ task_rule ]: the authority setting and operation rules of each node in the current task channel specifically comprise two aspects of a command Rule [ rule_C2] and an information Rule [ rule_interest ]. 4) Forced seat [ node_manager ]: a system node list which needs to be forcedly participated in the current task is designated in a digital identity form; 5) Open seat [ node_optinal ]: the seats of the participating nodes are not appointed temporarily, and the application of the nodes meeting the conditions in the system can be accepted or the subsequent appointments can be reserved; 6) Encryption communication method [ encryption_method ]: an encryption algorithm adopted by the current task channel; 7) Consensus rules [ Consensus ]: the nodes in the current task channel form a network consensus method mechanism. Wherein the task content and task rules are encrypted in an asymmetric manner, visible only to the node of the specified identity.
Task channel establishment: the method comprises the following specific steps: 1) Signing contract by digital identity by the finger control node of contract; 2) Encryption is submitted to corresponding nodes according to preset approval rules; 3) The command node with corresponding authority decrypts the contract and approves the contract, and the task contract passing the approval is issued to the blockchain network; 4) Establishing an encrypted communication link between nodes appointed by the forced seat, and initially establishing a task channel; 5) The open seat accepts node application in the system, and after the application passes or is designated again by the command node, the task channel establishment is completed; 6) The nodes in the task channel synchronize task contract content and initialize task storage.
Execution of the task: task execution is the process in which participants exert a combination of subjective motility and system informatization assistance. In the agile control system based on the blockchain, the task contract plays roles in the information flow and the control flow mainly by setting task execution logic and operation rules so as to realize the on-demand calling of information resources in agile control and the dynamic adjustment of the control relation.
The intelligence request is typically made by a task end node or a command control node, where the task end node is taken as an example to illustrate the system intelligence flow. Referring to fig. 3, the method specifically comprises the following steps: 1) The task terminal node puts forward an information request, wherein the information data hash to be accessed needs to be specified, and the information data hash is signed by own digital identity; 2) Requesting each node with authority in the submitting system to verify according to the information rule defined by the task contract; 3) If the verification is valid, the information resource node queries information data in the information base; 4) Returning to the task node which makes the request after the data query is successful; 5) After the data is returned, the contract generates information data event, submits the information data event to the system consensus process, and writes the information data event into the system event recording block.
The command instruction is sent by a command control node in the system, and the other command node or task terminal node executes the command instruction. In order to meet the requirement of constructing the dynamic command relationship, the system does not limit the forced corresponding relationship between the command node and the task node, but is judged and defined by the command rule in the task contract, so that the command can flow to other command nodes or any task terminal nodes by any command node under the verification of the system. Referring to fig. 4, taking an example that a command control node sends a command control instruction to a task terminal node, the main flow is as follows: 1) The command node formulates a command, wherein a task terminal node needing to finish the current command is specified, and the command node signs by own digital identity; 2) According to the command rule defined by the task contract, each node with authority in the command submitting system is verified; 3) If the verification is valid, the task terminal node starts to execute the command; 4) After the execution is finished, the task terminal node returns an execution result; 5) The task contract generates command events, submits the command events to the system consensus process, and writes the command events into the system event record block. In both processes, the communication between nodes is completed by means of the task channel. The node-node consensus mechanism can select the Raft and the PBFT algorithm of the alliance chain, and the like.
The present invention is based on blockchain technology, and thus differs from conventional database recording schemes. Transaction data in a blockchain system is stored and packaged in a hash chain structure after being confirmed by a system consensus process, and distributed backups are reserved in system nodes. The stored command and information event data is difficult to tamper and easy to verify, and can better support the requirements of multiple discs and audit.
In this embodiment, the event record model in the system mainly includes two types of information events and command events. Referring to fig. 5, the informative event mainly includes timestamp information, informative event label, request-to-propose node digital signature, verify node digital signature list, informative data hash value, etc.; the command event mainly comprises timestamp information, command event labels, command sending node digital signatures, verification node digital signature lists, command executing node digital signatures, command executing results and other information. The event records are arranged according to the time sequence, and the latter record contains the hash value of the former record, so that a close relation of front and back links is formed.
After a certain number of event records are stored, the system packages them into a block. As shown in fig. 6, each block contains several event records, and the block header contains information such as the time stamp of the block package, the block number, the Merkle root of all event records, etc. Similar to event logging, the blocks are linked back and forth by a hash value containing the previous block header.
The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above examples, and all technical solutions belonging to the concept of the present invention belong to the protection scope of the present invention. It should be noted that modifications and adaptations to the invention without departing from the principles thereof are intended to be within the scope of the invention as set forth in the following claims.
