Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, an embodiment of the present invention provides a method for monitoring concrete quality, including the following steps:
s1, receiving concrete related data uploaded by a user terminal at a plurality of stages, respectively generating evidence storage information for each concrete related data, and carrying out chain loading evidence storage through a block chain; the system comprises a plurality of stages, a concrete production stage, a concrete transportation stage, a witness sample submission stage, a test block maintenance stage, a third party detection stage, a concrete receiving and acceptance stage, a concrete pouring stage and an entity detection stage, wherein the plurality of stages sequentially comprise a raw material ordering stage, a raw material detection stage, a raw material mixing ratio stage, a concrete production stage, a concrete transportation stage, a witness sample submission stage, a test block maintenance stage, a third party detection stage, a concrete receiving and acceptance stage; the plurality of stages and the concrete related data are in one-to-one correspondence;
referring to fig. 2, in the embodiment of the present invention, step S1 is to associate data generated in each link from ordering to maintenance of concrete by using a block chain technique to form a data chain, so as to implement tracking of concrete and tracing when a quality accident occurs. The plurality of stages include a raw material ordering stage, a raw material detection stage, a raw material mixing ratio stage, a concrete production stage, a concrete transportation stage, a witness sampling inspection stage, a test block maintenance stage, a third party detection stage, a concrete receiving and acceptance stage, a concrete pouring stage and an entity detection stage, and the data generated in the whole life cycle from production to use of the concrete are subjected to block chain verification in the step S1. Specifically, the method comprises the steps of uploading area chain storage certificate on the ordering bill data of raw materials at the ordering stage of the raw materials of the concrete, uploading raw material detection data on the approach link of the raw materials, uploading finally determined mix proportion data at the mix proportion stage of the raw materials of the concrete, uploading concrete production data at the production stage of the concrete, uploading transportation bill and GPS positioning data of commercial concrete transportation at the transportation management stage, uploading witness sample data during witness sample transmission, uploading test block maintenance data during test block maintenance, uploading detection report at the third party detection stage, uploading slump during receiving and acceptance check, appearance quality assessment, chloride ion content detection data and acceptance bill, uploading concrete pouring position information data during concrete pouring, and uploading concrete poured entity detection data during entity detection. Preferably, the data which are not well acquired are automatically uploaded by the data acquired by the RFID chip, such as concrete production, pouring and maintenance.
S2, responding to a data query request of a management terminal, determining a target query stage according to the data query request, acquiring evidence storage information corresponding to the target query stage from the block chain and feeding back the evidence storage information to the management terminal; wherein the target query phase is at least one of the number of phases.
Referring to fig. 3, step S2 is to query the data related to the concrete when a project problem occurs, and trace the commercial concrete data for the data chain associated with the concrete in the whole life cycle from production to use, so as to assist in tracing the project quality accident. It can be understood that when concrete related data needs to be tracked, stages needing to be queried can be selected according to actual conditions, and data of all stages can be respectively queried in sequence according to needs so as to assist in tracking engineering quality accidents. By way of example, data queries may be performed in the following manner and order: the method comprises the steps of uploading entity detection data after concrete pouring during entity detection on a block chain, checking concrete pouring position information data during concrete pouring on the chain, checking slump uploaded during acceptance and acceptance on the chain, appearance quality assessment, chloride ion content detection data and an acceptance sheet, checking test block maintenance data in a test block maintenance stage on the chain, checking a detection report in a third party detection stage on the chain, checking evidence sampling data in a evidence sampling and sending process on the chain, checking a transportation sheet and GPS positioning data in transportation management in a transportation stage on the chain, checking concrete production data in a concrete production stage on the chain, finally determined mix proportion data in a concrete raw material mix proportion stage on the chain, checking raw material detection data in a raw material feeding link on the chain, and checking order sheet data of raw materials on the chain, and (4) checking which link has a problem, and then performing responsibility pursuit so as to determine the person responsible for the accident.
In an embodiment of the present invention, further, the method for supervising concrete quality further includes:
and S3, when judging that the evidence storing information corresponding to the target query stage does not exist in the block chain according to the data query request, judging that the stage corresponding to the target query stage is a data abnormal stage, and generating abnormal reminding information to feed back to the management terminal.
Step S3 is to determine that there is an abnormality in a certain stage when data in the stage needs to be queried but corresponding evidence storage data is not uploaded in the stage, and remind that special attention needs to be paid to perform focus pursuit. It should be noted that, in general, the cases where problems occur include: 1. data does not exist on the chain; reason for absence: 1) leakage transmission; 2) unqualified quality, fear of taking responsibility and intentional failure to transmit; 2. the data on the chain is problematic (for example, the mixing ratio of raw materials is not reasonable, and the raw materials are too diluted, so that the quality of concrete is problematic).
In this embodiment of the present invention, step S1 specifically includes:
s11, receiving concrete related data uploaded by a user terminal at a plurality of stages;
s12, responding the uplink request of the user terminal, generating evidence storing information according to the concrete related data in the uplink request, and identifying the evidence storing type of the uplink request.
S13, judging whether the certificate storing type of the uplink request is matched with a predefined type;
s14, if yes, packing the certificate storing information into a first block; wherein the first block comprises a first hash value generated from the concrete related data;
and when the certificate storing type of the uplink request is judged to be matched with the predefined type, the certificate storing information is put into a message pool to be packaged into a block, and then the data in the message pool is packaged and packaged into the block by the accounting node.
S15, recording the first block in the request initiating node corresponding to the uplink request, and triggering node synchronization operation.
Because each node on the block chain network stores one piece of service data information, and the account book data of each node is consistent, the problem that the data in the centralized database of the traditional centralized internet architecture is easy to lose or be tampered is solved.
It should be noted that, not only the concrete related data is packed into blocks and recorded in the nodes each time, but also the node information of the request initiated by the user is recorded, that is, the nodes contain the node information of the request initiated by the user, the certificate storing data, the hash value and the timestamp during packing, then all the information in the nodes is synchronized to each node of the block chain, and the concrete related data uploaded by the user is uploaded to the block chain in this way, so that the reliability of data certificate storage can be improved, the data is guaranteed not to be falsified and deleted by lawless persons, the problem of fraud of traditional mode managers is avoided, the uploaded data is transparent and can be inquired at any time, and when a certain link of engineering detection has a problem, the uploaded data can be traced back and asked for reason in real time.
In this embodiment of the present invention, further, the packaging the license information into a first block specifically includes:
dividing the evidence storage information into a plurality of partial data, and generating a second hash value corresponding to each partial data according to the user state data generated by the running environment and time of each partial data;
packing each part of data into the first block respectively; wherein the first block includes the second hash value and a first hash value generated from the concrete-related data.
In the embodiment of the invention, the complete data is taken as a whole when the data is uploaded, and a preset macroinstruction is triggered when the uplink request is sent out:
1. completely copying original data into data to be uploaded (evidence storing information);
2. dividing data to be uploaded into a plurality of parts of data, wherein the parts of data generate new user state data and cannot be modified;
and 3, uploading and packaging the separated parts of the data to be uploaded one by one under the condition that the network is smooth next, and generating corresponding hash values.
In step 3, the separated data are each a unit, and the unit data are continuously uploaded if the uploading is interrupted.
It should be noted that the new user state data includes an operating environment or time, and if the generation time or modification time of the divided data is inconsistent, the uploading of the original data fails, and the above steps 1, 2, and 3 are executed again. Preferably, the generated time is network time, and the local time cannot be used.
In this embodiment of the present invention, before recording the first block in the request initiating node corresponding to the uplink request and triggering a node synchronization operation, the method further includes:
performing encryption operation on the first block, performing double encryption on an encryption key generated by the encryption operation according to a preset random character adding rule, and generating a key compression packet corresponding to the block;
and combining the key compression packet with the corresponding first block to execute subsequent uplink operation.
It should be noted that, for the problem of cracking the hash value in the existing brute force cracking manner, a common scheme is to generate a key hash value or multiple hashes to improve information security.
In the embodiment of the invention, in order to solve the problem that the authenticity of data is difficult to verify due to the reasons of local storage damage, loss, client logout, main body extinction and the like of the generated key, key cloud storage can be set or public to a competent public authority department or a judicial department can be set, the key is added with random characters for compression, a chain is compressed, and the password setting condition is decompressed to trigger the public to the management department. For example, if the client is not on-line for three months or the client registers legal persons are unqualified, the most detailed data can be traced to the actual responsible persons when engineering problems occur.
As a specific example of the scheme, when a project quality problem needs to be traced back in the later period, a competent department can look up the concrete related data through a preset secret key, and the data are stored through an uploading block chain network, so that the defect that the data are falsified after the project problem occurs in the traditional management mode is avoided, the responsibility of each party can be better clarified, and whether the project quality problem is a material quality problem or a construction quality problem can be clarified. In addition, because the data also generate corresponding hash values when the chain storage certificate is stored, when the administrative department suspects the searched engineering data, the authenticity of the engineering data can be further verified by comparing the hash values generated by the engineering data with the hash values of the chain storage certificate.
In this embodiment of the present invention, further, before the responding to the uplink request of the ue, the method further includes:
judging whether the user terminal completes the identity identification of the information uploader;
if yes, responding to an uplink request sent by a user terminal, and generating a unique digital signature of the uploader for the uplink request;
otherwise, rejecting the uplink request response and feeding back uplink request failure information to the user terminal
