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.
Fig. 1 is a flowchart of a service implementation method for an internet of things terminal according to an embodiment of the present invention. The embodiment provides a service implementation method of an internet of things terminal, which is applied to a blockchain network shown in fig. 2, where at least one internet of things terminal is connected with an internet of things access gateway, and at least one internet of things access gateway and at least one server node form the blockchain network, it should be noted that the method provided by the present invention may be applied to the internet of things in any fields, such as fields of smart homes, smart cars, smart factories, and the like, in which the embodiment takes a smart home as an example for detailed description, and an execution main body of the method provided by the embodiment is the internet of things access gateway, and the method includes the following specific steps:
s101, the access gateway of the Internet of things acquires the service state of the terminal of the Internet of things connected with the access gateway of the Internet of things.
In this embodiment, because the internet of things terminal is connected with the internet of things access gateway, the internet of things access gateway can acquire the service state of the internet of things terminal connected with the internet of things access gateway, and can acquire the service state in real time or at a predetermined interval, for example, the internet of things terminal is an intelligent refrigerator, and the internet of things access gateway can acquire the working state of the intelligent refrigerator and/or the number of food and beverages stored in the intelligent refrigerator.
S102, the access gateway of the Internet of things judges whether the service state meets a preset condition.
In this embodiment, the access gateway of the internet of things can determine whether the service state meets a preset condition after acquiring the service state of the terminal of the internet of things, where the preset condition corresponds to the service content and serves as a trigger condition of the service content, and the preset condition may be a condition defined by an intelligent contract in a block chain or a condition set by a user. For example, if the service state is an intelligent contract in a block chain, the corresponding intelligent contract may be first searched for from the block chain according to the device type and/or the device identifier of the internet of things terminal, and then it is determined whether the service state satisfies a trigger condition agreed in the intelligent contract. For example, for an intelligent refrigerator, the internet of things access gateway may obtain an intelligent contract corresponding to the intelligent refrigerator from a block chain, where the intelligent contract may include a trigger condition for approvable maintenance and a trigger condition for automatic purchase, and may also include trigger conditions for other business contents, and the internet of things access gateway may compare a business state of the intelligent refrigerator with the trigger condition for approvable maintenance and the trigger condition for automatic purchase in the intelligent contract, respectively, to determine whether the trigger condition is satisfied, specifically, the internet of things access gateway obtains the quantity of a certain food and beverage in the intelligent refrigerator, and after comparing the quantity of the food and beverage defined in the trigger condition for automatic purchase agreed in the intelligent contract, determines that the quantity of the food and beverage in the intelligent agreed refrigerator is lower than the quantity of the food and beverage defined in the trigger condition for automatic purchase agreed in the intelligent contract, it is determined that the trigger condition for automatic purchasing is satisfied.
S103, if the judgment result is yes, the Internet of things access gateway selects an optimal server side node from the block chain network according to the service content corresponding to the preset condition, so that the server side node performs a service process with the Internet of things terminal according to the service content.
In this embodiment, if the internet of things access gateway determines whether the service state meets the preset condition, an optimal service node is selected from the blockchain network according to the service content corresponding to the preset condition, for example, when the internet of things access gateway determines that the service state of the intelligent refrigerator meets the trigger condition of automatic purchasing in the above example, an optimal food provider node (for example, closest distance, lowest price or best quality) can be selected from the blockchain network, a purchase order is sent to the food provider, and the food provider performs delivery, thereby completing the service flow of automatic purchasing; and if the access gateway of the Internet of things judges that the service state of the intelligent refrigerator meets the maintenance triggering condition, selecting the optimal service side node corresponding to the maintenance station or the after-sales service network from the block chain network, and maintaining the intelligent refrigerator by the service side node, wherein the service side node can be used for debugging the program of the intelligent refrigerator, and the service side node can be directly used for maintaining the intelligent refrigerator on line or used for maintaining the intelligent refrigerator off line. The block chain technology is a comprehensive body of technologies such as distributed data storage, point-to-point transmission, decentralized consensus mechanism, encryption and the like, and provides a credible mechanism for information and value transfer and exchange in an untrusted network, so that the safety of a business process between an internet of things terminal and a server side node can be improved by accessing the internet of things into the block chain network.
Further, before S103, the internet of things access gateway needs to access the block chain network in advance, and first the internet of things access gateway obtains a secret key after authentication, where the secret key includes a public key and a private key, and generates a network address of the block chain by using the secret key and its own account id, so as to access the block chain network.
And S104, after the business process is completed, the access gateway of the Internet of things writes corresponding business information and/or transaction information into a block and issues the business information and/or transaction information into the block chain network.
In this embodiment, after the service flow is completed, the access gateway of the internet of things writes the corresponding service information and/or transaction information into the block, and broadcasts the service information and/or transaction information to the blockchain network, so that each node in the blockchain network can verify the authenticity of the service information and/or transaction information, thereby implementing an automatic interactive service flow between nodes in the blockchain network, and implementing decentralized service management.
In the service implementation method of the internet of things terminal provided by this embodiment, the service state of the internet of things terminal connected to the internet of things access gateway is acquired through the internet of things access gateway; the access gateway of the Internet of things judges whether the service state meets a preset condition or not; if the judgment result is yes, the access gateway of the Internet of things selects the optimal service party node from the blockchain network according to the service content corresponding to the preset condition, so that the service party node performs a service process with the terminal of the Internet of things according to the service content; after the service process is completed, the access gateway of the internet of things writes corresponding service information and/or transaction information into the block and issues the service information into the block chain network, so that the service process between the access gateway of the internet of things and a server node in the block chain network is realized by the terminal of the internet of things, decentralized service management is realized, the intelligence of the internet of things is improved, better control and maintenance functions are provided for the internet of things, and higher safety is achieved.
On the basis of the foregoing embodiment, as shown in fig. 3, the determining, by the internet of things access gateway in S102, whether the service state meets a preset condition may specifically include:
s1021, the Internet of things access gateway searches a corresponding intelligent contract from the block chain according to the equipment type and/or the equipment identification of the Internet of things terminal;
and S1022, the access gateway of the Internet of things judges whether the service state meets the trigger condition agreed in the intelligent contract.
The intelligent contracts based on the block chains comprise a transaction processing and saving mechanism and a complete state machine, and are used for receiving and processing various intelligent contracts; and both the saving and state processing of the transaction are done on the blockchain. The transaction mainly comprises data needing to be sent; and events are descriptive information of such data. After the transaction and event information is transmitted into the intelligent contract, the resource state in the contract resource set is updated, and the intelligent contract is triggered to judge the state machine. And if the trigger conditions of a certain action or certain actions in the automatic state machine are met, selecting contract actions to be automatically executed by the state machine according to preset information. The intelligent contract system automatically sends out preset data resources and events comprising the trigger conditions from the intelligent contract according to the trigger conditions contained in the event description information when the trigger conditions are met; the core of the whole intelligent contract system is that the intelligent contract is processed by the intelligent contract module in a transaction and event mode and is also a group of transactions and events; the intelligent contract is a system consisting of a transaction processing module and a state machine, does not generate the intelligent contract, and does not modify the intelligent contract; it exists simply to allow a complex set of digitized commitments with trigger conditions to be correctly executed at the discretion of the participant.
In this embodiment, for a certain kind of internet of things terminal or an internet of things terminal with a certain device identifier, the service state and the corresponding service content of the internet of things terminal may be defined in the intelligent contract term, and the intelligent contract term may further include information such as transaction rules. The Internet of things access gateway searches a corresponding intelligent contract from the block chain according to the equipment type and/or equipment identification of the Internet of things terminal, then judges whether the service state of the Internet of things terminal meets the trigger condition agreed in the intelligent contract or not, if yes, then subsequently selects an optimal service party node, and the service party node performs service flow with the Internet of things terminal according to the corresponding service content in the intelligent contract.
The intelligent contracts can be jointly participated and established by a plurality of users in the blockchain network and can be used for any transaction behavior among the users. Both parties' rights and obligations are defined in the protocol, and are programmed electronically by developers, with the code containing conditions that trigger automatic execution of the contract. Once the intelligent contract is coded, the intelligent contract is uploaded to the block chain network, namely, the contract is received by all network verification nodes. The intelligent contract construction and execution are specifically divided into the following steps: 1) multiple users participate in making an intelligent contract together; 2) contracts are diffused through the P2P network and stored in block chains; 3) the intelligent contracts constructed by the block chains are automatically executed.
As a further improvement of the foregoing embodiment, in S103, the internet of things access gateway selects an optimal service node from the blockchain network according to the service content corresponding to the preset condition, and specifically may adopt any one of the following manners:
the first method is as follows: and the access gateway of the Internet of things searches the server nodes capable of realizing the service content from the block chain network and selects the optimal server node according to a preset strategy.
The second method comprises the following steps: the Internet of things access gateway generates a service request message according to the service content and issues the service request message to the block chain network;
and the Internet of things access gateway receives a service request response message sent by the service party node, and selects an optimal service party node from the service party nodes sending the service request response message according to a preset strategy, wherein the service request response message is sent to the Internet of things access gateway after each service party node receives the service request message and determines that the service content can be realized.
In the first mode, the internet of things access gateway searches in the blockchain network according to the service content to obtain all service side nodes capable of realizing the service content, for example, the service content is a service internet of things terminal, the internet of things access gateway searches in the blockchain network for service side nodes corresponding to a service station or an after-sales service network point capable of maintaining the internet of things terminal, and then selects an optimal service side node according to a predetermined policy, wherein the predetermined policy may be that the optimal service side node is selected according to at least one of factors such as distance (geographic position), service quality and price, for example, the service side node with the best service quality is selected as the optimal service side node, and the service side node completes a service flow corresponding to the service content with the internet of things terminal. It should be noted that the server node needs to publish its service content in the blockchain network in advance, which may specifically include the above factors such as geographic location, service quality, and price, so as to facilitate the internet of things access gateway to select the optimal server node.
In the second mode, the access gateway of the internet of things first generates a service request message according to the service content and issues the service request message to the blockchain network, that is, all the server nodes can receive the service request message, and acquires the service content from the service request message, each service side node determines whether the service content can be realized, if it is determined that the service content can be realized, a service request response message is sent to the internet of things access gateway, the internet of things access gateway can select an optimal server node from a plurality of server nodes sending the service request response message, the predetermined policy selected may be the same, and may of course be competitive by each server node, with the winning server acting as the optimal server node, wherein at least one of the factors of distance (geographical position), quality of service and price can be used as the index of the competition process.
It should be noted that, if there is only one server node capable of implementing the service content in the above process, the server node is directly selected as the optimal server node.
Further, in S103, after the internet of things access gateway selects an optimal service node from the blockchain network according to the service content corresponding to the preset condition, the method may further include:
and the Internet of things access gateway sends authentication information to the server node so that the server node verifies the identity of the Internet of things access gateway according to the authentication information.
In this embodiment, the blockchain network generates a public key and a private key in advance, where the public key is disclosed in the blockchain network, and the private key is stored in the access gateway of the internet of things, and the access gateway of the internet of things encrypts identity information of the access gateway of the internet of things, such as an account id, by using the private key to generate a digital signature, and sends the digital signature to the server node, so that the server node performs identity verification on the access gateway of the internet of things according to the public key and the digital signature, thereby improving the security of the service process. Of course, other authentication methods may be used, and are not described herein. It should be noted that the authentication process is not limited to be performed after the optimal server node is selected, and the authentication may be performed first when the internet of things access gateway performs any interaction process with each node in the blockchain network, and in addition, the internet of things access gateway may also perform authentication on the server node.
