Detailed Description
For the purposes, technical solutions and advantages of the present application, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Some embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart of a gateway device control method for the internet of things according to an embodiment of the present application. Some of the input parameters or intermediate results in the flow allow for manual intervention adjustments to help improve accuracy.
The implementation of the analysis method according to the embodiment of the present application may be a terminal device or a server, which is not particularly limited in this application. For ease of understanding and description, the following embodiments are described in detail with reference to a server.
It should be noted that the server may be a single device, or may be a system formed by a plurality of devices, that is, a distributed server, which is not specifically limited in this application.
The flow in fig. 1 includes the following steps:
s101: determining gateway equipment of a plurality of Internet of things equipment of a nano tube as a node of a blockchain, and deploying a preset intelligent contract to the blockchain; one gateway device corresponds to a preset intelligent contract, and the plurality of internet of things devices are located in the same industrial device.
In some embodiments of the present application, it is desirable to register the gateway device with data authentication so that it can act as a node of the blockchain.
Specifically, when the gateway equipment performs uplink, an asymmetric encrypted public-private key pair is generated through an elliptic curve digital signature algorithm. The elliptic curve digital signature algorithm may be an ECDSA algorithm, and the private key is stored in a secure hardware module (HSM) of the gateway device to prevent the private key from being acquired by an external attacker.
Then, node registration request information for the blockchain is generated from the gateway device identification information and the public key. The gateway equipment identification information comprises a gateway equipment MAC address and an equipment model.
And then, the node registration request information is sent to the existing gateway equipment node of the blockchain for consensus processing.
Then, it is determined whether the number of existing gateway device nodes agreeing to register exceeds a preset number threshold.
If yes, registering the gateway equipment, and determining the gateway equipment as a node of the blockchain. The node registration request information is packed into a new block.
If not, determining that the gateway equipment fails to register, and sending the registration failure information to the gateway equipment management user terminal equipment.
In addition, when the gateway device sends the data of the Internet of things device to the blockchain, the private key is utilized to sign the data of the Internet of things device, the data of the Internet of things device and the signature are sent to the blockchain together, and the node verifies the signature to ensure the integrity and the source of the data of the Internet of things device.
In some embodiments of the present application, the process of building a preset smart contract is as follows:
first, smart contracts are written using a resolution or other smart contract language to define conditions and rules for performing device operations. For example, when the temperature sensor reading exceeds a set threshold, the air conditioner is automatically turned on.
Then, the smart contract is compiled using Remix and a corresponding ABI (application binary interface) file is generated for deployment.
Then, after programming is completed, intelligent contracts are deployed to the blockchain, a Trufle framework or other deployment tool can be used, and each intelligent contract will have a unique address after deployment.
And finally, when the equipment data of the Internet of things meets the conditions defined by the intelligent contract, the corresponding gateway equipment node on the blockchain automatically calls the intelligent contract to generate a control instruction.
S102: and uploading the data of the Internet of things equipment to the blockchain through the gateway equipment in a preset period.
In some embodiments of the present application, when data of an internet of things device is uploaded to a blockchain, a hash algorithm is adopted, so that data security is improved. The internet of things equipment can collect environmental information such as temperature, humidity, illuminance and the like through the sensor.
Specifically, the gateway device performs hash calculation on the data of the internet of things device to obtain a first hash value, and performs digital signature on the first hash value through a private key.
It should be noted that, the gateway device may also perform preprocessing on the data of the internet of things device, such as data format conversion, data cleaning, and then perform hash calculation.
And then, carrying out hash calculation on the public key to obtain a second hash value, determining the second hash value as the identity information of the Internet of things equipment, and binding the second hash value with the Internet of things equipment data. Wherein the public key is used to verify the first hash value of the digital signature. Namely, a plurality of internet of things devices managed by the gateway device correspond to one piece of identity information.
The first hash value of the digital signature and the identification information are then uploaded to the blockchain.
The first hash value of the digital signature and the identification information are packaged into a transaction, and the transaction may include a timestamp, an internet of things device ID and other metadata besides the internet of things device data. Using the P2P network protocol, the transaction is broadcast into a blockchain network, where nodes verify the legitimacy of the transaction, such as the correctness of the signature.
After nodes in the blockchain network verify the validity of transaction data, the transaction is packed into a new block, the new block is added to the blockchain through a consensus mechanism, and the persistence of the data is ensured.
In addition, when historical device data needs to be retrieved, the gateway device may query the blockchain to quickly retrieve the required device data using a specific identifier (e.g., a timestamp or an internet of things device ID).
S103: and in the blockchain, when the data of the Internet of things equipment meets the condition of the preset intelligent contract, generating a target control instruction of the gateway equipment.
In some embodiments of the present application, due to the correlation between the operations of the components of the industrial equipment, the abnormality of the a component index may be caused by the B component index abnormality, or the abnormality of the a component a index is caused by the B component index abnormality of the a component, for example, the fan rotation speed is too high, resulting in the vibration of the bottom. Or the engine speed is too high, resulting in an excessive engine temperature. Based on the control instruction, under the condition that the abnormal data of the Internet of things equipment generate the control instruction, the industrial equipment does not need to execute all the control instructions, but executes the control instruction corresponding to the abnormal data of the equipment of one Internet of things equipment, so that the subsequent equipment data of the other Internet of things equipment can be recovered to be normal, the abnormal control efficiency of the industrial equipment is improved, and the workload of the gateway equipment is reduced.
Based on this, first, in a preset smart contract, a control rule of each of the internet of things devices is set, where a plurality of the internet of things devices may correspond to one control rule. Specifically, in order to monitor accuracy, since one component of an industrial device may place a plurality of internet of things devices of the same type, one control rule is corresponding to the internet of things device that monitors the same component of the industrial device and belongs to the same type of internet of things device.
And then, when the data of the Internet of things equipment meets the conditions of the preset intelligent contract, generating a plurality of initial control instructions of the gateway equipment.
Specifically, first, device data of each internet of things device is respectively input into a corresponding control rule. If the equipment data of the corresponding Internet of things equipment accords with the corresponding control rule, outputting an initial control instruction of the corresponding control rule, and marking the corresponding Internet of things equipment as target Internet of things equipment. Otherwise, if the device data of the corresponding internet of things device does not accord with the corresponding control rule, the initial control instruction of the corresponding control rule is not output.
So that a plurality of initial control instructions of the gateway device are generated after the initial control instructions corresponding to the control rules are output.
Then, each initial control instruction is subjected to association analysis, and initial control instructions with an execution priority relation are generated.
In some embodiments of the present application, the process of generating an initial control instruction with an execution priority relationship is as follows:
and taking all the Internet of things devices of the gateway device as nodes, and taking the association among all the Internet of things devices as edges to construct a knowledge graph of the gateway device.
And in the knowledge graph, searching each target Internet of things device to obtain the target Internet of things device with the dependency relationship. For example, the dependency may indicate that the abnormality of the a-part a index is caused by the b-index abnormality of the a-part, and that the control instruction corresponding to the abnormality of the a-part a index is caused by the b-index abnormality corresponding control instruction of the a-part.
When the initial control instruction comprises a first initial control instruction, a second initial control instruction and a third control instruction, if the first initial control instruction is determined to be caused by the second control instruction according to the dependency relationship, determining that the first initial control instruction has a priority relationship with the second initial control instruction, and determining that the execution priority of the first initial control instruction is higher than that of the second initial control instruction.
It should be noted that, a target internet of things device group with a dependency relationship may also be obtained. For example, d internet of things equipment has a dependency relationship with e internet of things equipment, and f internet of things equipment has a dependency relationship with g internet of things equipment.
And finally, generating a target control instruction of the gateway equipment according to the initial control instruction without the priority relation and the initial control instruction with the highest execution priority.
For example, the x control instruction does not have a priority relationship, the d internet of things equipment corresponds to the y control instruction, the e internet of things equipment corresponds to the z control instruction, the execution priority of the y control instruction is higher than that of the z control instruction, the f internet of things equipment corresponds to the w control instruction, the g internet of things equipment corresponds to the u control instruction, the execution priority of the w control instruction is higher than that of the u control instruction, and then the target control instruction is the x control instruction, the y control instruction and the w control instruction.
Wherein the target control instruction will also be recorded in the blockchain.
S104: and feeding back the target control instruction to the gateway equipment so that the gateway equipment forwards the target control instruction to the corresponding execution equipment.
In some embodiments of the present application, when serious anomalies occur in the data of the internet of things device, the gateway device immediately records the transaction and sends the transaction to the blockchain instead of uploading all the data of the internet of things device together in a waiting period.
Based on the data, the gateway equipment receives the newly-added Internet of things equipment data. When the newly-added Internet of things equipment data meets the requirement of immediately uploading the chain piece, immediately uploading the newly-added Internet of things equipment data to the blockchain. The immediate chain up piece is related to the severity of the failure of the internet of things device data presentation industrial device. When the data of the newly-added Internet of things equipment exceeds a preset serious threshold value of the type of the Internet of things equipment, the data of the newly-added Internet of things equipment is immediately uploaded to the blockchain.
In some embodiments of the present application, the running states of all connected internet of things devices are managed on a blockchain, so that consistency and instantaneity of data are ensured.
In addition, when the running state of the internet of things equipment changes, the gateway equipment records the change information as a transaction and sends the transaction to the blockchain.
In some embodiments of the present application, all gateway devices synchronize data from the blockchain periodically, ensuring that the local data is consistent with the data on the blockchain; when the data is inconsistent, the gateway device automatically updates the local data to ensure the synchronization with the data on the blockchain.
Based on this, first, on-chain data is synchronized from the blockchain within a preset time interval. And then, acquiring the local on-link data stored by the gateway equipment. The local on-chain data is then compared to the on-chain data.
If not, the local on-chain data is updated to on-chain data. If the data on the local chain are consistent, the data on the local chain are not updated any more.
It should be noted that, due to the distributed nature of the blockchain, the expansibility of the system is greatly improved, and the increase of the number of gateway equipment nodes can be easily dealt with.
It should be noted that, although the embodiment of the present application is described with reference to fig. 1 to sequentially describe steps S101 to S104, this does not represent that steps S101 to S S104 must be performed in strict order. The steps S101 to S104 are sequentially described according to the sequence shown in fig. 1 in the embodiment of the present application, so as to facilitate the understanding of the technical solution of the embodiment of the present application by those skilled in the art. In other words, in the embodiment of the present application, the sequence between the steps S101 to S104 may be appropriately adjusted according to the actual needs.

In addition, the data and the control instructions of the Internet of things equipment are recorded on the blockchain, so that the transparency of the data and the operation is realized, and the auditing and the fault investigation of the gateway equipment control system are facilitated.
