All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, a blockchain-based non-process dust removal centralized monitoring system of the present application is shown, which may include a data acquisition subsystem, a blockchain server, and a non-process dust removal centralized monitoring platform; wherein:
the data acquisition subsystem is used for acquiring parameter information of the dust removal system and uploading the parameter information to the block chain server; wherein the parameter information comprises a plurality of different types of physical quantity data, and the physical quantity data is from different devices in the dust removal system.
It should be noted that, in this embodiment, the dust removing system generally includes a plurality of dust removing devices, and the dust removing devices will generate a large amount of parameter information during the daily operation. Specifically, the parameter information may include one or more of dust emission data, fan vibration data, fan temperature data, equipment pressure difference data, and energy consumption data, where the energy consumption data may include an amount of electricity and/or water consumption of the dust removal system.
In this embodiment, the data acquisition subsystem 1 may be configured based on a wireless sensor network, where the network includes a plurality of sink nodes (including a dust emission data sink node, a fan vibration data sink node, and an energy consumption data sink node), and a plurality of sensor nodes of the same type are connected to the same sink node, and the sensor sub-nodes are respectively used for acquiring dust emission data, fan vibration data, and energy consumption data in the dust removal system.

And the block chain server 2 is used for classifying the parameter information according to different types in the parameter information and uploading the classified parameter information to a block chain for distributed storage.
In this embodiment, by classifying the parameter information and uploading the classified parameter information to the blockchain, the same type of parameter information can be in the same node in the blockchain. Because the updating rule of the parameter information of the same type is basically the same, when the data is updated, only the corresponding node needs to be updated, so that the calculation cost and the storage cost of the whole blockchain can be effectively reduced, and the storage pressure of the blockchain server 2 can be effectively reduced. Meanwhile, based on the characteristics of non-tampering, traceability and the like of the block chain technology, the tracking of parameter information is guaranteed, and the safety and the accuracy of energy consumption data are improved.
The non-process dust removal centralized monitoring platform 3 comprises a query module, a display module and an alarm module; the query module is used for sending a parameter checking request to the blockchain server 2 and acquiring parameter information returned by the blockchain server 2 in response to the parameter checking request; the display module is used for displaying the parameter information in the form of a statistical chart and/or a table; the alarm module is used for acquiring alarm signals sent by the blockchain server 2 under the condition that the parameter information exceeds a parameter threshold value, and sending corresponding alarm information according to the alarm signals.
It should be noted that, the query module may perform manual query by a user, or may perform automatic query by setting a preset query time through the platform. In this embodiment, in order to facilitate the user's inquiry, the non-process dust collection centralized monitoring platform 3 may set different inquiry directories, such as a dust collection dust emission inquiry directory, a national control environmental protection equipment emission inquiry directory, a vibration data inquiry directory, a fan bearing temperature inquiry directory, an equipment pressure difference inquiry directory, a steel slag energy consumption inquiry directory and a dust collection energy consumption inquiry directory, on the front page, the user may check corresponding equipment data by clicking a corresponding virtual button to enter the corresponding directory after logging in the non-process dust collection centralized monitoring platform 3.

The user can look up the parameter information of all the devices in the query subdirectory by clicking the virtual button corresponding to the query subdirectory. For ease of administration, the user may also add and delete devices by clicking on a virtual edit button.
In this embodiment, in order to enable a user to more quickly, accurately and intuitively understand a large amount of parameter information, the display module of the non-process dust removal centralized monitoring platform 3 may further display the parameter information through a large monitoring screen according to the queried parameter information, which is favorable for effectively monitoring, counting and analyzing each device in the dust removal system, and improving the monitoring management efficiency.
Specifically, the real-time parameter information of the equipment in the dust removing system can be displayed on a large monitoring screen in the form of a statistical chart or a table. In one example, a graph may be used to show a real-time plot of the hourly dust emissions of the target device, with a bar graph showing the total dust emissions currently accumulated. It should be noted that, the displayed content can be switched according to the needs of the user, for example, when the query condition is a single device, the dust emission curve graph of the device is displayed; when the query condition is a workshop or an area, a dust emission curve chart of all devices in the workshop or the area is displayed.
In this embodiment, in order to ensure that when the operation of the device is abnormal, relevant personnel can be notified at the first time, corresponding parameter thresholds, such as a dust emission threshold, a fan vibration threshold, a fan temperature threshold, a device pressure difference threshold and the like, are set in the blockchain server 2 for different types of physical quantity data, so that when the acquired parameter information exceeds the corresponding parameter threshold, the blockchain server 2 can send an alarm signal to the non-process dust removal centralized monitoring platform 3 at the first time, and sends corresponding alarm information through the alarm module. The alarm signals comprise one or more of dust alarm signals, fan vibration alarm signals, fan temperature alarm signals and equipment pressure difference alarm signals.
In this embodiment, the fan vibration data includes: the data of the X phase of the front shaft of the fan, the Y phase of the front shaft of the motor, the X phase of the rear shaft of the fan, the Y phase of the rear shaft of the fan and the Y phase of the rear shaft of the motor; the fan temperature data includes: temperature data of a front shaft and a rear shaft of the fan. Therefore, when the alarm signal outputs the fan vibration alarm signal and the fan temperature alarm signal, the specific abnormal part of the fan can be further output, so that targeted processing can be performed, and the maintenance efficiency is improved.
In this embodiment, it should be further described that different alarm levels may be set according to the priority of the alarm signal, for example, the dust alarm signal may be set as a first-level alarm level as a serious fault.

In a possible implementation manner, the non-process dust removal centralized monitoring platform 3 further comprises a data management module and a report management module, wherein:
and the data management module is used for maintaining and storing the acquired parameter information.
In this embodiment, by storing the parameter information locally, the queried energy consumption data can be directly invoked when the data analysis is performed, so that the data loss or repeated query is avoided. Meanwhile, after the user logs in the non-process dust removal centralized monitoring platform 3 and can go through authentication, the user manually inputs data by clicking an edit virtual button to calibrate parameter information, and after the calibration, a calibration record is left, wherein the calibration record comprises an input calibration value and calibrated parameter information, so that the modification record is traceable.
In this embodiment, the data management module further includes a trend prediction unit, where the trend prediction unit is configured to predict parameter information from the current time to a future time according to historical parameter information of the historical time and the current time input by a user, where a difference between the future time and the current time and a difference between the current time and the historical time are the same.
In this embodiment, on the basis of displaying the parameter information graph, the corresponding parameter information trend may also be predicted by the historical parameter information. In one example, if the user outputs the dust emission trend of ten days in the future of the target device, a straight line from ten days before to the current time is drawn according to the historical dust emission data of ten days before the current time, and the straight line is extended to a time scale corresponding to ten days in the future, so that the trend prediction of the energy consumption data is realized.
And the report management module is used for counting the parameter information and automatically generating a corresponding data report according to the user requirement. As one preferable scheme, the report management module automatically generates a data report at intervals of a second preset time interval, and stores the data report to the data management module.
In this embodiment, the report management module may automatically generate a report required by a user, such as a daily dust emission statistics table, a daily fan temperature statistics table, a monthly electricity consumption statistics table, and the like, according to a preset generation rule by reading parameter information stored in the data management module.
In one possible embodiment, the data acquisition subsystem 1 comprises a data acquisition terminal and a data encryption module; wherein:
and the data acquisition terminal is used for acquiring the parameter information of the dust removal system and sending the parameter information to the data encryption module.
The data encryption module is used for encrypting the parameter information by adopting a preset private key and uploading the encrypted parameter information to the blockchain server 2.
In the embodiment, the private key is adopted to encrypt the parameter information, so that the confidentiality and the security of the data can be ensured, namely, only the owner of the private key can acquire the parameter information, further, other enterprises or users are prevented from acquiring the parameter information of the enterprise, the data uploading stage is prevented from being forged or tampered by other people, and the integrity and the authenticability of the data are effectively ensured.
In one possible embodiment, the blockchain server 2 includes a first receiving module, a second receiving module, a classification module, a first storage module, and a search module; wherein:
the first receiving module is used for receiving the encrypted parameter information uploaded by the data encryption module and analyzing the encrypted energy consumption data so as to facilitate the subsequent data processing; wherein the parameter information includes a corresponding device identification. Specifically, the device identifier may include a workshop identifier, a device type and a device number of the device, so that detailed information of the target device can be quickly obtained in a data query stage.
The classification module is used for classifying the parameter information according to different types in the parameter information and adding corresponding type identifiers for the parameter information.
And the first storage module is used for uploading the classified parameter information to the block chain for distributed storage.
The second receiving module is used for receiving the energy data viewing request sent by the non-process dust removal centralized monitoring platform 3.
And the searching module is used for searching and screening parameter information corresponding to the energy data viewing request from the blockchain according to the energy data viewing request sent by the non-process dust removal centralized monitoring platform 3 and returning the parameter information to the non-process dust removal centralized monitoring platform 3.
In this embodiment, after the user logs in the non-process dust removal centralized monitoring platform 3, the user can check the parameter information of the dust removal equipment in the corresponding area by entering the corresponding query subdirectory, and can directly locate the specific dust removal equipment by inputting the corresponding equipment identifier.
In one possible implementation, the first storage module includes a blockchain unit, an acquisition unit, an update unit, a consensus unit; wherein:
a block chain unit for acquiring a block chain composed of a plurality of memory blocks; the storage block comprises a block head and a block body, the block body comprises a merkel tree, and the block head comprises a tree root of the merkel tree and a hash pointer of the preamble storage block.
In this embodiment, the nodes of the blockchain will consist of several memory blocks, each including a block header and a block body. Wherein the storage area block comprises a merkel tree storing parameter information; the memory block head stores the information such as the tree root of the merkel tree, the hash pointer of the preamble memory block, and the time stamp. The tree root of the mekel tree is the block hash value of the storage block, which is also called the hash value of the storage block, and is placed in the storage block header for data verification, the hash pointer of the preceding storage block is used for pointing to the hash value of the previous storage block, and the storage blocks are sequentially connected to form the blockchain in the embodiment through the front-to-back pointing relation of the hash pointer of the preceding storage block. The Hash (Hash) is a function of mapping data with any length into data with a fixed length, and the data with the fixed length is the finally obtained Hash value.
In this embodiment, the merkel tree is also called a hash tree, and is divided into two parts, namely a binary tree and a transaction sequence, where the transaction sequence is used as a child node of the whole merkel tree and corresponds to the child node of the binary tree one by one, and in this embodiment, is used to store parameter information. And the binary tree part takes the hash value of the parameter information from the value of the child node, and the father node of the tree is the hash value of the combination of the two child nodes. The characteristic of the Meeker tree is that any change to the bottom node is transferred to the father node, up to the tree root, and the changed leaf node is easy to locate, so that the Meeker tree is especially suitable for quick, effective and safe verification of the existence and integrity of data. The use of the merkel tree increases the difficulty of data tampering, and can realize effective recording of time sequence changes of parameter information.
The obtaining unit is used for obtaining the classified parameter information and writing the hash value corresponding to the parameter information of the same class into the child nodes of the same subtree in the merkel tree.
It should be noted that, the subtree is taken as one tree branch of the merkel tree, and a pair of child nodes under the same subtree corresponds to the same parent node, that is, two child nodes plus the corresponding parent node can be regarded as a subtree with a minimum unit. The existing distributed storage scheme based on the blockchain does not consider the updating rule of the data, but is randomly distributed to the child nodes for storage, and each time of data updating, the change on a path from a parent node corresponding to the child node to a tree root is caused. In one example, two paths change if two data in different subtrees are updated at the same time.
In this embodiment, the update rules of the same type of parameter information are basically the same, so when the hash values corresponding to the same type of parameter information are written into the child nodes of the same subtree in the mekel tree, it means that when the parameter information is updated at the same time, only the change from the parent node corresponding to the child node to one path of the tree root is caused, and further the change of multiple paths caused by the fact that the parameter information is stored in different subtrees is avoided, so that the hash calculation times and corresponding storage cost can be effectively reduced, and meanwhile, the storage pressure of the blockchain server 2 is effectively reduced.
The updating unit is used for acquiring current parameter information according to a first preset time interval and generating a corresponding current hash value according to the current parameter information; and writing the current hash value into the corresponding child node to replace the original hash value of the child node, and obtaining the updated Meeker tree.
The first preset time interval may be actually set according to different types of energy consumption, for example, dust emission data may be set to be collected once every half hour, fan vibration data may be set to be collected once every ten seconds, fan temperature data may be set to be collected once every minute, and energy consumption data may be set to be collected once every twenty-four hours. The first preset time interval is not specifically limited, and the first preset time interval is set according to actual needs.
And the consensus unit writes the updated tree root of the Meicher tree and the hash pointer of the corresponding preamble storage block into the corresponding block header, and broadcasts the block header to other blocks in the block chain to realize consensus and obtain the updated block chain.
In this embodiment, after the merkel tree is updated, broadcasting is performed by writing the updated tree root of the merkel tree and the hash pointer of the corresponding preamble block into the corresponding block header, so as to inform the latest parameter information of other blocks, thereby realizing consensus and obtaining the updated block chain.
