In this embodiment, by taking intelligent elevator management based on a blockchain technology and intelligent remote slope safety monitoring management in a infrastructure as an example, a specific implementation process of the provided blockchain multi-chain management method for the intelligent infrastructure is described. For example, the method for intelligent management of the elevator is as follows:
The method comprises the steps of defining a station area in a ladder for each person with elevator operation authority, setting a joint angle range allowed when each button in the elevator is operated for each person, judging whether the person in the ladder falls into the station area, judging whether the weight of the person in the station area is matched with the weight of the person with elevator operation authority, judging whether the height of the person in the station area is matched with the height of the person with elevator operation authority, judging whether the joint angle of the current operation elevator button of the person in the station area falls into a corresponding joint angle range allowed, and finally judging whether the person in the station area has elevator operation authority.
In order to realize intelligent management of whether personnel having authority to operate the elevator, a blockchain network is constructed, namely a first business chain is formed, a plurality of blockchain nodes are arranged on the first business chain, each blockchain node is used for storing business data generated by corresponding management links in elevator intelligent management, for example, a super ledger uploads recorded personnel information of the authority to operate the elevator to the first blockchain node of the first business chain through executing chain codes, intra-elevator station location information defined for personnel having authority to operate the elevator is stored to the second blockchain node of the first business chain, joint angle range information preset for personnel having authority to operate the elevator is stored to the second blockchain node of the first business chain, a real-time acquired elevator taking image is stored to the third blockchain node of the first business chain, station location number information of personnel identified from the acquired elevator taking image is stored to the fourth blockchain node of the first business chain, binding relation information between personnel having authority to operate the elevator and corresponding station location number is stored to the fifth blockchain node, and the weight of the personnel having authority is stored to the first blockchain node of the first business chain is stored to obtain the weight information of the first blockchain.
Similarly, assume intelligent management of remote slope safety monitoring, which relates to slope management personnel information data, slope discrete data, slope safety monitoring equipment information and equipment installation position information data, and safety monitoring data of each equipment on a slope, and a blockchain network constructed for the intelligent management of the remote slope safety monitoring is called a second service chain, and the service chain is provided with 4 blockchain nodes which are respectively used for correspondingly storing the slope management personnel information data, the slope discrete data, the slope safety monitoring equipment information and equipment installation position information data, and safety detection data of each equipment on the slope.
The above-mentioned configuration of the first service chain and the second service chain, i.e. the blockchain multi-chain management method for the intelligent infrastructure provided in the present embodiment as shown in fig. 1:
step S1, setting service chains, and uploading service data generated by each intelligent infrastructure service scene to a corresponding service chain by a super account book, wherein each block chain node on each service chain stores the service data of a corresponding service link under the same scene;
In order to realize unified management of different block chain nodes in a multi-hop service chain, the block chain multi-chain management method aiming at intelligent infrastructure provided by the application comprises the following steps:
Step S2, setting a management chain, wherein the management chain comprises 2 management nodes, namely a business personnel data management node (used for uniformly managing personnel information data on a plurality of business chains) and a business data management node (used for uniformly managing business data on a plurality of business chains);
After the service chain and the management chain are set, the service chain and the management chain are required to be linked together so as to realize unified management of multiple chains. In the application, the service chain with the highest data storage value is found out from a plurality of service chains in a data value calculation mode, then the block chain node storing high-value data is further found out from the service chain as a link node, and a personnel information acquisition module and a service data acquisition and processing module are constructed for the link node, in the subsequent service analysis, the data required by the service analysis is acquired from the corresponding block chain nodes of the corresponding service chain by taking the link node as a data acquisition inlet through the two modules, and the high-value data required by the service analysis can be acquired from the block chain node quickly because the block chain node storing the high-value data is found in advance, thereby avoiding missing to acquire the high-value data and ensuring the data acquisition to be more targeted.
In order to obtain data more pertinently and realize effective management of multiple chains, the block chain multiple chain management method based on intelligent infrastructure provided by the application further comprises the following steps:
Step S3, constructing a link node corresponding to each management node, wherein the link node comprises a first link node and a second link node, and the first link node links the block chain nodes used for storing personnel information data in all service chains to the service personnel data management node, for example, in FIG. 2, the first block chain nodes in the first service chain are linked to the first block chain nodes in the second service chain, and then are themselves linked to the service personnel data management node. The second link node links each block link point for storing service data in all service chains to a service data management node, for example, in fig. 2, after the fourth block link point in the second service chain is linked to the second to seventh block link nodes in the first service chain, the second link node is itself linked to the service data management node, and the service data management node is connected to the service analysis system. Therefore, by setting the first connecting node and the second connecting node, the data interaction among multiple chains is realized.
In order to achieve synchronous acquisition of data of multiple chains, the intelligent infrastructure-based blockchain multiple chain management method provided by the application further comprises the following steps:
Step S4, a personnel information acquisition module is constructed for the first link node, and a service data acquisition and processing module is constructed for the second link node;
Step S5, in each business analysis, acquiring personnel information data required by the business analysis from each blockchain node linked by the first link node through a personnel information acquisition module, for example, when judging whether elevator passengers have elevator operation rights or not, acquiring the personnel information data required by judgment from the first blockchain node of the first business chain shown in figure 2 through the personnel information acquisition module, when analyzing the current safety condition of a remote side slope, acquiring the personnel information data required by analysis from the first blockchain node of the second business chain shown in figure 2 through the personnel information acquisition module,
And the service data acquisition and processing module acquires the service data required by service analysis from each block chain node connected with the second link node, the service data acquisition and processing module packages the personnel information data related to the acquired service analysis and each service data and then sends the data package to the service analysis data management node, for example, when judging whether elevator passengers have elevator operation rights or not, the service data acquisition and processing module acquires the service data required by judgment from the second to seventh block chain nodes of the first service chain shown in fig. 2, and then the service data acquisition and processing module packages the acquired service data and the personnel information data acquired by the first link node and then sends the packaged service data to the service analysis data management node.
Here, since the determination of whether the elevator personnel has the elevator operation authority is progressive, it may not be necessary to acquire all the service data stored in the second to seventh blockchain nodes in the first service chain when the determination of whether the elevator personnel has the elevator operation authority is made, but the elevator image acquired in real time is the data that the determination of the elevator personnel must have anyway, and thus the data stored in the second to seventh blockchain nodes has a score of high value, if the second link node is the fourth blockchain node storing the elevator image in the first service chain or the fourth blockchain node storing the safety monitoring data in the second service chain shown in fig. 2, the data required for the service analysis having high value may be acquired directly at the second link node, and the link skip is not necessary when acquiring the high value data, and the speed of data acquisition is also faster, so it is very important on which blockchain node of which service chain the link node is set. In the application, since the first link node is only used for acquiring the personnel information data, one of the block chain nodes used for storing the personnel information data in each service chain can be selected as the first link node, and the speed of acquiring the service data is not greatly influenced. And because the second link node links all the blockchain nodes used for storing business data on all chains, the setting position of the second link node has great influence on the data acquisition speed and the pertinence of the data acquisition, the setting position of the second link node is determined by introducing a data value score calculation mode, and the specific mode method comprises the following steps:
Step S31, designating the first link construction factor corresponding to each second link construction factor in the second service chain from the first link construction factors in the first service chain, where the meaning of the first link construction factor and the second link construction factor is shown in the following table a:
Table a
The "elevator operator name", "whether to pre-set an intra-elevator site area" and the like in the above table a can have an influence on the selection of the setting position of the link node, and are therefore called connection construction factors, and further, the link construction factors in the first service chain are called first link construction factors, and the link construction factors in the second service chain are called second link construction factors.
The assignment of the correspondence between the first link construction factor and the second link construction factor refers to, for example, in the above table a, that the elevator operator name and the slope name are both name-type link construction factors, so that it may be assigned that the two link construction factors have correspondence. In addition, in the table a, the first link construction factor of whether the elevator taking image is acquired or not and the second link construction factor of whether the monitoring device acquires the monitoring data are both link construction factors of a real-time data acquisition class, so that the two link construction factors can be designated to have a corresponding relation, the essence of the designated corresponding relation is to preliminarily designate the block chain node which is manually considered to store high-value data in each service chain, the purpose is that the data in the block chain nodes with the corresponding relation among multiple chains can be firstly acquired through the link nodes when the multiple chains are synchronously acquired later, the missing of the acquisition of the data which is manually considered to be required for the analysis with high value is avoided, and the pertinence and the acquisition speed of the data acquisition are improved.
The data corresponding to each link construction factor associated with the same person or slope constitutes a piece of business data.
Step S32, calculating the data value score of each service chain through the following formula (1):
in the formula (1), Representing the data value score corresponding to the kth service chain;
Values representing an ith first link construction factor in jth service data in kth service chain or an ith second link construction factor in jth service data in kth service chain, the values "1" and "0" in table a above; for convenience of calculation, the value of each link construction factor in each service chain is expressed by 0 and 1;
Representation/> At calculation/>The weight occupied by the time; for example, when judging whether the person has the elevator operation right or not by the joint angle when the elevator person operates the elevator button, giving a larger weight to the link construction factor of "whether the joint angle range is preset or not";
n represents the number of the first link construction factor or the second link construction factor in the jth service data in the kth service chain;
m represents the number of pieces of service data in the kth service chain, such as one piece of service data for each action in table a;
step S33, for having Each first link construction factor or each second link construction factor in the kth service chain of the maximum value, the difference S between each link construction factor and the second link construction factor or the first link construction factor having the correspondence relation described in step S31 is calculated by the following formula (2), for example, the difference between the first link construction factor of "whether or not to collect the riding image" and the second link construction factor of "whether or not to collect the monitoring data" having the correspondence relation in the table a is calculated:
In the formula (2), Representation has/>The value of the ith first link construction factor or the ith second link construction factor in the jth business data in the kth business chain of the maximum value;
m 1 denotes a compound having The number of service data in the kth service chain of the maximum value;
representing the o and/>, of the p-th business data in another business chain participating in the calculation of the degree of difference s A value of the corresponding first link construction factor or second link construction factor;
m 2 represents the number of business data in another business chain participating in the calculation of the difference degree s;
step S34, will have And taking the block chain node corresponding to the first link construction factor or the second link construction factor with the smallest difference degree s in the kth service chain with the largest value as a second link node.
In order to obtain data required for service analysis more quickly and accurately when the multi-link is obtained in data synchronization, more preferably, in step S5, data required for service analysis is first obtained from the second link node and/or from the designated blockchain node having the correspondence relationship described in step S31 with the second link node, and then data required for service analysis is obtained from other blockchain nodes in the service chain where the second link node is located and/or from other blockchain nodes in the service chain where the designated blockchain node is located.
After the data is obtained, as shown in fig. 1, the blockchain multi-chain management method for intelligent infrastructure provided by the application is transferred to the last step, namely:
And S6, the service analysis data management node sends the received data packet to a service analysis system for service data analysis.
