Description
Technical Field
The invention relates to the technical crossing field of the Internet of things and block chain information, in particular to an indoor air detection data uplink method and equipment of the Internet of things by combining 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. Currently, indoor air may be seriously polluted after indoor decoration due to unqualified materials, such as the indoor formaldehyde exceeds the standard. In addition, if the indoor ventilation is not in place, the indoor oxygen concentration may be insufficient, which is not beneficial to the health or normal life of indoor personnel, and therefore, the indoor air environment needs to be detected.
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 indoor air detection data after combining the blockchain technology with the internet of things further improve user experience, which becomes a challenge of the future technologies.
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 link indoor air detection data of the Internet of things.
In order to achieve the above object, in a first aspect, the present invention provides an indoor air detection data uplink method for an internet of things in combination with a block chain, including the following steps:
indoor empty gas detection survey data that the empty gas detection survey server of block chain node receipt sent, indoor empty gas detection survey data is gathered by air detector, sends for empty gas detection survey server through the thing networking, and indoor empty gas detection survey data includes: oxygen concentration and formaldehyde concentration;
and carrying out identity verification on the air detection server by the block chain node, and if the identity verification is passed, carrying out cochain on the indoor air detection data by the block chain node after common identification.
Specifically, the identity verification is to verify the indoor air detection data sent by the air detection server through a public key of the air detection server; the indoor air detection data is data signed with an air detection server private key.
Optionally, the air detector is placed in the detected room, and the air detector includes: and the formaldehyde detector and the oxygen concentration detector are respectively used for detecting the formaldehyde concentration and the oxygen concentration. And sending the indoor air detection data to an air detection server through the Internet of things. And then the air detection server sends the indoor air detection data to the block chain nodes.
Further, the air detector can directly send detected indoor air detection data to the block chain nodes 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 indoor air detection data to the blockchain node through the air detection server may be a preferable scheme.
Specifically, the block link point performs link up after the PBFT consensus on the indoor 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 indoor air detection data, a transaction including a hash of the indoor air detection data and 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, and thus, multi-party evidence storage of the indoor air detection data is realized. When the transaction only includes the hash of the indoor air detection data, since the hash of the indoor air detection data is already issued to the blockchain, if the indoor air detection data is tampered, the hash of the tampered indoor air detection data is inconsistent with the hash issued in the blockchain, and therefore, issuing the indoor air detection data to the blockchain is equivalent to multi-party verification of the indoor air detection data. It should be noted that when the transaction only includes the hash of the indoor air detection data, the blockchain certification platform typically stores the indoor air detection data in a data warehouse (non-blockchain), such as a 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 indoor air detection data, and sends the query result of the indoor air data to the user according to the query request of the user.
In one possible embodiment, the block link point receives the indoor air detection data, and when the block link point determines that the user is in the room, the block link point directly pushes the indoor air data to the user.
In one possible embodiment, the block link point uplink the indoor air detection data, which includes the following steps:
if the data volume of the indoor air detection data is larger than the storage threshold value of one block, dividing the indoor air detection data into a plurality of fragment data smaller than the storage threshold value by a block chain node;
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 block link point uplink the indoor air detection data, which includes the following steps:
if the data volume of the indoor air detection data is larger than the storage threshold value of one block, dividing the indoor air detection data into a plurality of fragment data smaller than the storage threshold value by a block chain node;
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 amount of the indoor air detection data to be sent is too large and is greater than the set data capacity threshold, the hash value of the indoor air detection data may be calculated, and the hash value is sent to the blockchain node for uplink. When a user inquires the indoor air detection data, whether the indoor 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 indoor air detection data, whether the indoor air detection data is tampered or not is judged, and the indoor air detection data storage and authenticity supervision based on the air detection server and the block chain are achieved.
In one possible embodiment, the indoor air detection data is structured data, and each attribute of the indoor air detection data is linked, where the attribute of the indoor air detection data includes: indoor address and detection time.
In one possible embodiment, the method further comprises the steps of:
the method comprises the steps that a 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 indoor 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 indoor air detection data is to obtain the block chain resource used for uplink of the indoor air detection data by mortgage of certain digital currency, and pay the uplink fee of the indoor air detection 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 indoor air detection data is sent to the block chain nodes in a mortgage mode, the uplink fee is not sent independently during each uplink, but block chain resources are consumed, and the uplink fee of the indoor 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 indoor air detection data may be replaced by: the aerial detection server sends indoor aerial detection data to the block chain node in a transfer mode so that the block chain node can execute a chain loading process, wherein transfer information sent by the aerial detection server comprises: from address, to address, room air detection data, commission charge. 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 uplink of the paid indoor air detection data.
Wherein the commission may be digital currency.
It can be understood that after the air detection server passes the authentication of the block link point, the resource fee check is also needed before the indoor air detection data is uplink. The resource fee means: and the resource size required by the uplink of the received indoor air detection data, wherein 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.
