Description
Technical Field
The invention relates to the technical crossing field of the Internet of things and block chain information, in particular to an ambient air detection data uplink method and device of the Internet of things based on a block chain.
Background
The blockchain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism and an encryption algorithm. The consensus mechanism is a mathematical algorithm for establishing trust and obtaining rights and interests among different nodes in a blockchain system. The blockchain is the underlying technology of bitcoin, like a database ledger, which records all transaction records. The system is characterized in that a plurality of nodes are arranged at different parts of the world, and each node maintains a set of same databases. The data is maliciously tampered and difficult to tamper, and the data loss is extremely rare, so that a platform which is fair and transparent and solves the trust crisis is realized.
In the era of the development of the internet of things along with the information technology such as the internet and the like, a sensor, a user, an object and the like are connected together in a new mode, and the information, remote monitoring and management and intelligent network are realized. Ambient air safety is currently an increasing concern for society, such as: the ozone concentration, the sulfide concentration, the nitride concentration, the inhalable particle concentration and the like of the environment, if the environmental air index is not beneficial to the physical health of residents or environmental workers, the residents or the environmental workers need to be informed, and the environmental air data can be inquired.
Since the blockchain is a development direction of future technologies, how to combine the blockchain technology with the internet of things and how to link the ambient air detection data after combining the blockchain technology with the internet of things, user experience is further improved, and a challenge of the future technologies is presented.
The above techniques are merely for reference and are not necessarily to be construed as prior art.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to solve the technical problems of how to combine the block chain technology with the Internet of things and how to detect the uplink of the data by the ambient air of the Internet of things.
In order to achieve the above object, in a first aspect, the present invention provides an ambient air detection data uplink method for a block chain based internet of things, including the following steps:
the ambient air that the air detection server sent is received to district's chain node detects data, ambient air detects data and is gathered by air detector, sends for the air detection server through the thing networking, and ambient air detects data and includes: air quality index, sulfur dioxide concentration, nitrogen dioxide concentration, inhalable particulate concentration, ozone concentration, and carbon monoxide concentration;
and carrying out identity verification on the air detection server by the block link point, and if the identity verification is passed, carrying out cochain on the environment air detection data by the block link point after common identification.
Specifically, the identity verification is to verify the ambient air detection data sent by the air detection server through a public key of the air detection server; the ambient air detection data is data signed with an air detection server private key.
Optionally, the air detector is placed in the detected environment, the air detector comprising: the device comprises a sulfur dioxide detector, a nitrogen dioxide detector, an inhalable particle detector, an ozone detector, a carbon monoxide detector and an air quality index calculator, wherein the sulfur dioxide detector, the nitrogen dioxide detector, the inhalable particle detector, the ozone detector, the carbon monoxide detector and the air quality index calculator are respectively used for detecting the sulfur dioxide concentration, the nitrogen dioxide concentration, the inhalable particle concentration, the ozone concentration and the carbon monoxide concentration and calculating the air quality index. The air detector detects ambient air, and sends ambient air detection data to the air detection server through the Internet of things. And the air detection server sends the ambient air detection data to the block chain nodes.
Further, each air detector can directly send detected ambient air detection data to the blockchain node through the internet of things. It can be understood that the connection of the air detection server to the blockchain node is more stable than the connection of each air detector to the blockchain node. Therefore, a mode of sending the ambient air detection data to the blockchain node through the air detection server may be taken as a preferable scheme.
Specifically, the block link point performs link up after the PBFT consensus on the ambient air detection data by using the PBFT fault-tolerant algorithm.
It should be noted that the blockchain is a distributed ledger, and may be a private chain, a public chain, or a federation chain.
Specifically, when the block chain nodes receive the ambient air detection data, a transaction including a hash of the ambient air detection data and the transaction information thereof can be constructed, and the constructed transaction is broadcasted to the block chain network, so that each node stores the transaction in its own block chain based on a consensus mechanism, thereby realizing multi-party evidence storage of the ambient air detection data. When the transaction only includes the hash of the ambient air detection data, since the hash of the ambient air detection data is already issued to the blockchain, if the ambient air detection data is tampered, the hash of the tampered ambient air detection data is inconsistent with the hash issued in the blockchain, and therefore, issuing the ambient air detection data to the blockchain is equivalent to multi-party crediting of the ambient air detection data. It should also be noted that when the transaction only includes a hash of the ambient air detection data, the blockchain attestation platform typically stores the ambient air detection data in a data store (non-blockchain), such as RAM.
It should be noted that the transaction described in this specification refers to a piece of data that is created by a user through a client of the blockchain and needs to be finally published to a distributed database of the blockchain. That is, there are narrow and broad categories of transactions in the blockchain. A narrowly defined transaction refers to a transfer of value issued by a user to a blockchain; for example, in a conventional bitcoin blockchain network, the transaction may be a transfer initiated by the user in the blockchain. The broad transaction refers to a piece of business data with business intention, which is issued to the blockchain by a user; for example, an operator may build a federation chain based on actual business requirements, and rely on the federation chain to deploy some other types of online businesses unrelated to value transfer, such as data uplink business, house renting business, vehicle scheduling business, insurance claim settlement business, and the like, in such federation chain, a transaction may be a business message or business request with business intent issued by a user in the federation chain.
In one possible embodiment, the block chain node receives the ambient air detection data, and the block chain node sends the query result of the ambient air data to the user according to the query request of the user.
In one possible embodiment, the block link point receives the ambient air detection data, and when the block link point determines that the user is in the environment, the block link point directly pushes the ambient air data to the user.
In one possible embodiment, the uplink of the ambient air sensing data by the block link point includes the following steps:
if the data volume of the ambient air detection data is larger than the storage threshold value of one block, dividing the ambient air detection data into a plurality of fragment data smaller than the storage threshold value by a block link point;
the block chain node stores a plurality of fragment data into a plurality of blocks of the block chain node respectively.
In one possible embodiment, the uplink of the ambient air sensing data by the block link point includes the following steps:
if the data volume of the ambient air detection data is larger than the storage threshold value of one block, dividing the ambient air detection data into a plurality of fragment data smaller than the storage threshold value by a block link point;
the block link point stores a first piece of fragment data in the plurality of pieces of fragment data to a current block link point;
and the block chain nodes randomly select other block chain nodes except the current block chain link point in a mode of verifying a random function VRF, and the other block chain link points store the data except the first piece of fragment data in the plurality of pieces of fragment data.
Alternatively, if the air detection server determines that the data size of the ambient air detection data to be sent is too large and is greater than the set data capacity threshold, the hash value of the ambient air detection data may be calculated, and the hash value is sent to the blockchain node for uplink. When a user inquires the ambient air detection data, whether the ambient air detection data stored on the air detection server is real or not can be verified through inquiring the hash value on the link point of the block and the corresponding relation between the hash value and the original ambient air detection data, whether the ambient air detection data is tampered or not is judged, and storage and authenticity inquiry of the ambient air detection data based on the air detection server and the block chain are achieved.
In one possible embodiment, the ambient air sensing data is structured data, and each attribute of the ambient air sensing data is linked, where the attribute of the ambient air sensing data includes: the environmental geographic location and the time of detection.
In one possible embodiment, the method further comprises the steps of:
the block chain node receives digital currency mortised by an air detection server, and allocates corresponding resources for the air detection server, wherein the resources are used for uplink of environmental air detection data sent by the air detection server; the resources include: network resources, CPU resources, and memory resources.
Specifically, in the above scheme, the uplink mode of the ambient air sensing data is to obtain the block chain resource used for uplink of the ambient air sensing data by mortgage of a certain digital currency, and pay the uplink fee of the ambient air sensing data at the block chain link point.
It is understood that the allocated blockchain resource may be a CPU, a network resource NET or a RAM. The method includes the steps that the ambient air detection data are sent to the block chain nodes in a mortgage mode, the uplink fee is not sent independently in each uplink, but block chain resources are consumed, and the uplink fee of the ambient air detection data at the block chain nodes can be paid only by obtaining the block chain resources through the mortgage.
Optionally, in the above scheme, the uplink mode of the ambient air detection data may be replaced by: the air detection server sends the environmental air detection data to the block chain node in a transfer mode so that the block chain node can execute a chain loading process, wherein the transfer information sent by the air detection server comprises: from address, to address, ambient air detection data, commission fees. Specifically, the from address is an address of the air detection server, the to address is an address of the blockchain node, and the commission is a cost of resources occupied by the uplink of the paid ambient air detection data.
Wherein the commission may be digital currency.
It can be understood that after the identity verification of the air detection server by the block link point is passed, resource fee check is also required before uplink is performed on the ambient air detection data. The resource fee means: the resource size required by the uplink of the received environment air detection data, and the resource fee check refers to judging whether the resource purchased by the air detection server is larger than the resource fee, if so, the resource fee check is passed, otherwise, the check is not passed.
In a second aspect, the present invention provides an ambient air detection data uplink device for a block chain based internet of things, including:
