Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein.
The embodiment of the invention is mainly applied to a small block chain network scene consisting of a plurality of intelligent household devices. Generally, a blockchain is a shared database in which data or information stored therein has characteristics of being unforgeable, being traceable throughout, being traceable, being maintained collectively, and the like. With the gradual maturity of the block chain technology, the block chain is used as a decentralized distributed database and is very suitable for scenes of the internet of things such as smart homes.
Fig. 1 shows a schematic structural diagram of an intelligent home network provided by an embodiment of the present invention. The smart home network is a small block chain network, and comprises a plurality of device nodes, such as user terminal devices (mobile phones, personal computers, tablet computers, vehicle-mounted terminals, special terminals and the like), gateways, refrigerators, washing machines, air conditioners, televisions, water heaters, electric rice cookers, smart speakers and other smart home devices. These nodes can be classified into master nodes and general nodes according to their functions. The main node comprises intelligent equipment such as a user terminal or a gateway and the like which can access the internet, and other intelligent home equipment can be called common nodes. The nodes in the network are connected with each other through a local area network constructed by the gateway, and when the user terminal is positioned outside the local area network, the user terminal is connected with the gateway through the Internet and is connected with other nodes through the gateway.
In order to accurately record the operation data of a user on a certain device node, the main node can obtain a time stamp for marking the occurrence time of the operation from a clock source. The clock source comprises: wireless base station, internet clock source, long-short wave time service system or satellite positioning system. For example, the smart phone serving as the master node can synchronously acquire accurate current time from the wireless base station in real time; the mobile phone, the gateway and the like can acquire accurate current Time from an internet clock source through a Network Time Protocol (NTP). If the long and short wave time service module is integrated in the node, the standard time can be obtained from a long and short wave time service system (BPL/BPM); if the node is integrated with a satellite positioning module, standard time can be obtained from a GPS or Beidou satellite positioning system. If the intelligent household equipment serving as the common node detects that the intelligent household equipment has the function of acquiring time data from the clock source, the intelligent household equipment broadcasts to the main node after the intelligent household equipment is added into the block chain network, the main node sets the intelligent household equipment as a timing backup node, and if the main node cannot directly acquire accurate time from the clock source due to faults, the standard time is acquired from the clock source through the timing backup node so as to ensure the accuracy and the stability of time stamp acquisition.
Optionally, according to the stability and the difficulty of timing of the clock source, setting the priority of the clock source from high to low as: the wireless base station > Internet clock source > long and short wave time service system > satellite positioning system. That is, the master node preferentially acquires the standard time from the wireless base station, and acquires the standard time from other clock sources when the master node fails to acquire the standard time.
In an optional embodiment, in order to ensure that the smart home network has the function of the block chain technology, each node structure in the network may include an application layer, a consensus layer, and a device layer.
The application layer may include a user manipulation module and a block chain management module. The user control module is used for man-machine interaction, and a user initiates operation to the equipment through the module; the block chain management module is used for managing the recording mode and the consensus mechanism of the block data.
The consensus layer may comprise a node interconnect module. The node interconnection module is used for managing and controlling network interconnection among the nodes and conversion of various protocols, and stable and effective network communication among the nodes is guaranteed. For the master node in the network, the consensus layer can further comprise a clock check module. The clock check module is used for providing a credible time base for a consensus mechanism of the intelligent home network, namely, the clock source can obtain reliable time data and provide credible timestamp query service for each node in the network.
The equipment layer can comprise a node block chain module and an equipment automatic control module. The node block chain module is used for being connected with each node in the network through the node interconnection module, and the operation of chain encryption, a recording mode or a consensus mechanism of each block in the whole block chain is realized under the control of the block chain management module. The equipment automatic control module is a control module of the equipment node own operating system, and interacts with the node block chain module through a specific protocol to realize the translation and execution of instructions.
Of course, the node structure is an exemplary example, and the specific structure may be set by an equipment manufacturer according to the equipment condition, and may be implemented in a hardware manner or a software manner, as long as it is ensured that the node structure can be linked with each node in the smart home network in a block chain function. The new smart home device with the blockchain function needs to be registered to join the smart home network and becomes a node in the blockchain network.
Fig. 2 is a flowchart of an operation data recording method provided by an embodiment of the present invention, which is applied in the above network based on a block chain. The method may be executed by each node in the smart home network, and for convenience of description, the node executing the method may be referred to as an operation data recording node. As shown in fig. 2, the method comprises the steps of:
step 210: and responding to the operation of the user on the first node, and acquiring the timestamp of the operation occurrence time.
The timestamp is used to mark the time of occurrence of the operation performed by the user on the first node. The first node is a target node operated by a user. For example, the user wants to set the cooling function of the air conditioner, which is the first node, to be turned on at six pm. The user can directly operate the first node, can operate the first node through the master node, and can operate the first node through a second node (such as an intelligent sound box) supporting an intelligent home management function. That is, the operation data recording node includes a master node, a first node, or a second node. Correspondingly, in an optional embodiment, step 210 specifically includes:
step 211: and responding to the operation of the user on the first node, and acquiring current time data from a clock source to generate a timestamp.
Under the condition that a user operates the first node through the master node, if the user sets that the air conditioner starts a refrigeration function at six afternoon through a mobile phone, the master node responds to the operation of the user on the first node, obtains current time data from the clock source and generates a timestamp.
Optionally, if the network includes a time correction backup node, the master node acquires the current time data from the clock source through the time backup node to generate a timestamp. In an optional embodiment, the master node periodically calibrates the local time to the clock source acquiring time data, and in some cases, when the current time data cannot be acquired from the clock source, the timestamp is generated by using the current time data provided by the clock source as the local time periodically calibrated to the clock source.
In an alternative embodiment, step 210 specifically includes:
step 212: and responding to the operation of the user on the first node, and sending a timestamp acquisition request to a main node in the network.
Under the condition that a user directly operates the first node or operates the first node through the second node, if the user directly sets on an air conditioner or sets that the air conditioner starts a refrigeration function at six pm through an intelligent sound box, the first node or the second node responds to the operation of the user on the first node and sends a timestamp acquisition request to a main node in a network. Specifically, the node block chain module in the first node or the second node may send a timestamp obtaining request to the master node.
Step 213: and receiving a timestamp sent by the master node, wherein the timestamp is generated by the master node according to the current time data acquired from a clock source.
Specifically, after receiving the timestamp obtaining request, the master node obtains current time data from the clock source to generate a timestamp, and sends the timestamp to the first node or the second node. Similarly, the master node may obtain the current time data from the clock source through the time backup node to generate the timestamp. In an alternative embodiment, the master node generates the time stamp using the local time periodically calibrated to the clock source as the current time data provided by the clock source.
Optionally, in order to ensure that the timestamp is authentic and authentic, the master node may encrypt the timestamp with a private key of the master node to generate a digital signature, and send the timestamp and the digital signature to the first node or the second node. In particular, the timestamp and the digital signature may be sent to a node blockchain module in the first node or the second node.
In particular, the operations associated with the master node in step 210 may be performed by a clock checking module in the master node.
Step 220: and generating an operation record marked with the time stamp, wherein the operation record comprises operation data of the user for operating the first node.
Optionally, if the operation data recording node is the first node or the second node, and the timestamp and the digital signature are obtained from the master node, step 220 may include:
step 220 a: and after receiving the timestamp and the digital signature, decrypting the digital signature by using the main node public key to obtain the decrypted timestamp.
Specifically, after receiving the timestamp and the digital signature from the master node, the node block chain module in the first node or the second node may obtain the public key of the master node from the block chain management module, and decrypt the digital signature with the public key to obtain the decrypted timestamp.
Step 220 b: and comparing the time stamp with the decrypted time stamp, and if the time stamp is consistent with the decrypted time stamp, verifying that the time stamp is credible.
Specifically, the first node or the second node compares the timestamp with the decrypted timestamp, and if the timestamp is consistent with the decrypted timestamp, the timestamp is verified to be authentic. If not, the verification fails, the first node or the second node feeds back a message of the trusted timestamp acquisition failure to the user, and the execution of the method is stopped.
Through the verification step of the timestamp, a malicious node can be prevented from falsifying a false timestamp to disturb data records by serving as a main node, so that the safety and the stability of operation record storage in a block chain are ensured.
The operation data in step 220 specifically includes an identifier of the first node, instruction data, and the like, where the instruction data includes instruction time and instruction content, such as six pm, refrigeration mode on, temperature 26 degrees, duration 1 hour, and the like. The operation record comprises a timestamp of the occurrence time of the operation and operation data.
Step 230: and sending the operation record to each node in the network, so that each node stores the operation record in a block by taking the operation occurrence time as the sequence according to the timestamp.
Specifically, the operation data recording node (the main node, the first node or the second node) broadcasts the operation record to the smart home blockchain network. After receiving the operation record, each node performs consensus operation and synchronously stores the operation record in a consistent way. Of course, the operation data recording node synchronously stores the operation records in the blocks in the sequence of the operation occurrence time according to the time stamp.
In an optional embodiment, each node stores an operation record through a first temporary block; the step of the above nodes storing the operation records in the block according to the time stamps and the operation occurrence time as the sequence may specifically include: each node judges whether the number of operation records in the first temporary block exceeds a preset block height, and if not, the operation records are stored in the first temporary block in sequence by taking the operation occurrence time as the time stamp; and if the operation record exceeds the normal operation record, converting the first temporary block into a normal block, generating a second temporary block, and storing the operation record in the second temporary block by taking the operation occurrence time as the sequence according to the timestamp.
The block height refers to the number of operation records that can be accommodated in one block. The block height may be uniformly set in advance in each node of the block chain network, for example, 100, each node writes 100 operation records in a temporary block and then converts the operation records into a formal block to generate a hash value, and simultaneously generates a new temporary block, and writes the hash value into a hash head of the newly generated temporary block to form chain encryption.
It should be noted that in the application scenarios of the blockchain technology in the fields of finance, big data, etc., each node in the blockchain needs a certain workload value to compete for the billing right, so the design of the consensus mechanism of the large blockchain is complex. Common Consensus mechanisms include workload certificates (PoW), rights and interests certificates (PoS), Stellar Consensus Protocol (SCP), Practical Byzantine Fault-tolerant mechanisms (PBFT), Pool verification mechanisms, etc., and because these Consensus mechanisms involve complicated mathematical and logical operations, the entire block chain network generates a very large system overhead, which makes it difficult to meet the requirements of real-time data interaction.
And block link points in the field of the internet of things of the smart home do not need to compete for the accounting right in most cases when the data records of the linked list are counted. If the user can operate the first node on the operation data recording node such as the main node, the first node or the second node, the main node, the first node or the second node has the accounting right, and the operation record of the first node can be broadcasted to each node in the blockchain network to perform the consensus operation. In order to solve the problem of ordering the operation records in the consensus mechanism, the method uses the time stamps to store the operation records in the blocks in the order of the operation occurrence time. Therefore, a simple, efficient and practical consensus mechanism is ingeniously realized, and the ordered distribution of the accounting rights of all the nodes is realized. Compared with the complex consensus algorithm, the block chain network adopting the operation data recording method provided by the embodiment of the invention has the advantages of low operation overhead, high response speed and the like, and is very suitable for small block chain networks such as smart homes.
After each node in the block chain network synchronously stores the operation record, when each node recognizes that the operation record is related to itself, namely the identifier of the first node in the operation data is consistent with the identifier of the node, the node executes the instruction content at the instruction time according to the instruction data in the operation data. If the air conditioner node recognizes that the identifier of the first node is consistent with the identifier of the first node, the cooling mode is started at six pm according to the instruction data, and the temperature is set to be 26 ℃ for 1 hour.
The operation records stored in the intelligent home block chain network can be queried and traced by a user, and new equipment can be inherited conveniently. For example, when a user changes a certain device node in the network, after a newly added node registers to join the network, an operation record in a certain time range can be acquired from any node in the network, the operation record of the previous device node of the same type is inquired, so that the operation preference of the user is found, and the personalized customization function is pushed to the user according to the user preference. If newly-added air conditioning equipment finds that the user often turns on the air conditioning refrigeration function at about 6 o 'clock in the afternoon by inquiring the historical operation records, the option of turning on the air conditioning refrigeration function at 6 o' clock in the afternoon can be pushed to the user for the user to select and set.
According to the operation data recording method provided by the embodiment of the invention, when a user operates a first node in an intelligent household equipment network based on a block chain, a timestamp of an operation occurrence is obtained, an operation record marked with the timestamp is generated, and the operation record is sent to each node in the network, so that each node can consistently store the operation record in a block according to the timestamp and by taking the operation occurrence time as a sequence. By the method, the operation data of the user on the equipment node can be accurately recorded, and the backtracking and inheritance of the historical operation data are facilitated. In addition, due to the adoption of a decentralized block chain distributed storage technology, operation records are uniformly stored in each node in the network, the problem that remote control records of intelligent equipment are unavailable easily when a server fails or equipment operation record time delay is large due to the fact that the cloud server is overloaded is solved due to the fact that single-point management of the cloud server is avoided, the safety, the stability and the timeliness of operation data records are guaranteed, and user experience is improved.
