Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Referring to fig. 1 and 2, the method for processing data of an IOT device based on a dual-heavy chain is applied to a system including a cloud server and a plurality of IOT devices, wherein the cloud server is connected to the plurality of IOT devices respectively, and the IOT devices are divided into a plurality of groups; the data processing method comprises the following steps:
s101, broadcasting the first hash value of each IOT device in the group to other IOT devices in the group to construct a single chain among the IOT devices in the group;
s102, broadcasting the second hash value of the optional IOT device in each single chain to the optional IOT devices in other single chains to construct the heavy chain of the IOT devices among the groups;
s103, carrying out data synchronization of IOT equipment in the group based on the single chain;
and S104, performing data synchronization of the IOT devices among the groups based on the heavy chains.
The cloud server is provided with a plurality of IP pools, and each IP pool is provided with an IP address of the IOT equipment in the same group;
specifically, the step S101 of broadcasting the first hash value of each IOT device in the group to other IOT devices in the group to construct a single chain between the IOT devices in the group includes:
each IOT device in the group acquires the IP addresses of other IOT devices in the group from the corresponding IP pool on the cloud server; broadcasting a first hash value uniquely corresponding to one IOT device to other IOT devices in the group; the other IOT devices in the group receive the broadcasted first hash value and respond to create a single chain.
In this embodiment, the method for constructing the single chain includes two parts, which are an initial constructed chain and a dynamic updated chain.
The process of initially building the chain includes:
s201, each IOT device in the group acquires initial data of the IOT device;
specifically, the initial data includes a first device parameter of the IOT device, where the first device parameter at least includes a unique identifier of the IOT device, and may further include one or more of a production date, a manufacturer, a repair date, a model number, and the like. The initial data may be stored on the IOT device or on the cloud server.
S202, each IOT device acquires the IP addresses of other IOT devices from the IP pool on the cloud server.
Specifically, each IOT device is installed with a terminal device including a 4G module, and based on the terminal device, the IOT device can access the internet.
The cloud server stores the IP addresses of the IOT devices (terminal devices) interacting with the cloud server into an IP address pool, and each IOT device in the group can acquire the IP addresses of other IOT devices from the IP pool on the cloud server so as to carry out mutual communication and construct a single chain. In addition, when the IOT devices in the group change, for example, a new IOT device is added or an IOT device is deleted in the group, the cloud server adds or deletes the IP address, notifies other IOT devices in the group, and establishes or deletes a corresponding chain to perform data synchronization or to no longer perform data synchronization.
S203, each IOT device in the group generates a first hash value based on the first device parameter of the IOT device, and broadcasts the first hash value to other IOT devices in the group.
S204, each IOT device in the group receives the broadcasted first hash value and responds to establish a single chain.
Specifically, the generation of the first hash value may be based on any existing algorithm, which is not specifically described in the embodiments of the present invention, as long as the parameter of the hash function is the initial IOT device parameter.
The specific process of broadcasting may be implemented by sending a message to other IOT devices based on the obtained IP address. Specifically, any IOT device may send a request message for establishing a chain to other IOT devices in the group, where the request message includes the first hash value of the IOT device, and at the same time, includes a field indicating that a chain is established in the message; and other IOT devices in the group receive the first hash value and return response messages. When each IOT device in the group has the first hash value of the other IOT devices in the group, the initial build chain is successful.
Referring to FIG. 3, a group includes four IOT devices, which need to be grouped into a single chain. During initialization, the cloud server stores the IP addresses of the four IOT devices in an IP pool, and each IOT device acquires the IP addresses of the other three IOT devices. In the subsequent interaction process, each IOT device generates a respective hash value based on the initial IOT device parameter and broadcasts the hash value to other IOT devices, and when receiving confirmation messages replied by the other three IOT devices, it indicates that the IOT device broadcasts the first hash value successfully, that is, the link establishment is completed.
It should be noted that the initial building chain is described by calculating the first hash value on each IOT device. In actual application, the first hash value may be calculated by the cloud server and then sent to the corresponding IOT device, and then the corresponding IOT device broadcasts to other forklifts in the group, or the cloud server broadcasts directly to all IOT devices in the group.
In this embodiment, since data of each IOT device may change, in order to further ensure the security of the data, when the IOT device has data that changes, a single-chain dynamic update needs to be performed, where the process of the dynamic update chain includes:
s301, when data of a certain IOT device in the group changes, a new first hash value is calculated based on the dynamic forklift parameters and is broadcasted to all IOT devices in the group.
S302, each IOT device in the group receives the broadcast new first hash value and responds to establish a single chain.
Specifically, the dynamic forklift parameter at least includes a forklift unique identifier, and may also include part or all of dynamically updated data.
Specifically, the generation of the new first hash value may be based on any existing algorithm, and may be consistent with or inconsistent with the foregoing calculation method of the initial first hash value.
The specific process of broadcasting may be implemented by sending a message to all IOT devices in the group based on the IP addresses stored in the IP address pool. Specifically, the data update IOT device may send a request message for updating the single chain to other IOT devices in the group, where the request message includes a new first hash value of the data update IOT device, and at the same time, includes a field indicating establishment of the chain in the message; the other IOT devices in the group receive the new first hash value and return response messages.
It should be noted that the above process of dynamically updating the chain is described by calculating the first hash value on each IOT device. In actual application, the first hash value may be calculated by the cloud server and then sent to the corresponding IOT device, and then the corresponding IOT device broadcasts to other forklifts in the group, or the cloud server broadcasts directly to all IOT devices in the group.
Specifically, the S102 broadcasts the second hash value of the optional IOT device in each single chain to the optional IOT devices in other single chains to construct the heavy chain of the inter-group IOT device, including:
one or more IOT devices are arbitrarily selected from any single chain to serve as external nodes, and one or more IP addresses are selected from other IP pools stored by the cloud server; broadcasting a second hash value uniquely corresponding to the selected IOT device to other groups of the selected IOT devices; the other group of selected IOT devices receives the broadcasted second hash value and responds to establish the heavy chain.
In general, one IOT device is selected from each single chain as a node for constructing the heavy chain. For some application scenarios, in order to further ensure the security of data, two or three IOT devices may be selected from each single chain as nodes for constructing the heavy chain, so that it may be ensured that when a problem occurs in one pair of external nodes, the external nodes may be switched to another pair of external nodes. Problems that may arise include hardware damage, slow node network speeds, or heavy node tasks. For example, two external nodes a1 and B1 are selected on a C1 chain, two external nodes a2 and B2 are selected on a C2 chain, and a1 and a2 constitute one chain, but B1 needs to keep heartbeat with a2 and B2, B2 needs to keep heartbeat with a1 and B1, when the a1 node cannot communicate with a2 within a certain time, the node is switched to B1, at this time, it is considered that a1 has a fault, and B1 replaces the position of a 1.
Further, the above construction method of the re-chain may also include two parts, namely an initial construction chain and a dynamic update chain, and the specific implementation process is consistent with the construction method of the single chain, and will not be described repeatedly here.
Referring to fig. 4, the IOT devices are divided into two groups, each group includes four IOT devices, and the four IOT devices in the two groups respectively construct a single chain. After the single chains are constructed, selecting an IOT equipment node (IOT-1 and IOT-2-1) from each single chain to construct the heavy chain, specifically, the IOT-1 and the IOT-2-1 send the respectively calculated second hash value to the opposite side, and when receiving a confirmation message replied by the opposite side, the fact that the sending of the second hash value is successful indicates that the construction of the heavy chain is completed.
Specifically, the S103 performs data synchronization of the IOT devices in the group based on the single chain, including:
s401, the IOT equipment of the first data synchronization party sends a hash value verification request to other IOT equipment in the single chain; the other IOT equipment in the single chain compares the sent hash value with the stored first hash value of the IOT equipment of the first data synchronizer, and if the hash value is consistent with the stored first hash value, the IOT equipment of the first data synchronizer sends a verification passing response message to the IOT equipment of the first data synchronizer;
s402, the IOT equipment of the first data synchronizer counts the proportion of response messages passing the verification, and if the proportion is larger than or equal to a first preset value, the IOT equipment of the first synchronized party synchronizes data.
Referring to FIG. 3, if IOT-1 has data changed, IOT-1 is the IOT device of the first data synchronizer; IOT-2, IOT-3 and IOT-4 are first synchronized IOT devices; IOT-1 synchronizes the change data to IOT-2, IOT-3 and IOT-4.
Specifically, referring to fig. 5, a specific flow of synchronizing data from the IOT device a to the IOT device B is shown, where the first preset value is 50%, and is specifically set according to actual needs.
Specifically, the S104 performs data synchronization of the inter-group IOT device based on the heavy chain, including:
s501, the IOT device of the second data synchronizer sends a hash value verification request to other IOT devices in the heavy chain; the other IOT equipment in the heavy chain compares the sent hash value with a stored second hash value of the IOT equipment of the second data synchronizer, and if the hash value is consistent with the stored second hash value, the IOT equipment of the second data synchronizer sends a response message that the verification is passed to the IOT equipment of the second data synchronizer;
s502, the second data synchronizer IOT equipment counts the proportion of response messages passing the verification, and if the proportion is larger than or equal to a second preset value, the data are synchronized to the second synchronized IOT equipment.
Referring to FIG. 4, if IOT-1 has data changed, IOT-1 is the second data synchronizer IOT device; IOT-2-1 is a second synchronized IOT device; IOT-1 synchronizes the change data to IOT-2-1.
When the intra-group IOT device data synchronization is performed based on a single chain and the inter-group IOT device data synchronization is performed based on a heavy chain, the synchronized IOT device includes one or more devices. The above-described verification process of the hash value needs to be performed only once if the synchronizer IOT device needs to synchronize data to all other IOT devices in the single chain or heavy chain at the same time. If the synchronizing IOT device needs to synchronize data to other IOT devices in a single chain or heavy chain at different times, verification of the hash value is required before each synchronization, even if the same data is synchronized.
In this embodiment, the data processing method further includes:
and uploading the processing result of the dynamic updating data of the IOT equipment to the cloud server for storage by the IOT equipment. That is, data on each IOT device is not only synchronously saved to other IOT devices in the single chain or the heavy chain, but also needs to be saved to the cloud server.
Further, the data processing method further includes:
after uploading the processing result of the dynamic updating data of the IOT equipment to the cloud server, deleting the expired data according to a preset rule by the IOT equipment; the expiration data is set according to time.
For example, only data within a preset time (e.g., about 1 year) is stored on the IOT device, other data of historical data for more than 1 year is deleted, and when the deleted data is needed, the data is obtained by the cloud server, so that the data is not lost.
