In the transmission of main common recognition node whether know together after the confirmation request for completing the block, if not received within scheduled first time
Based on the corresponding confirmation message of the confirmation request, then the heart is sent to the main common recognition node for not receiving the corresponding cluster of confirmation message
Jump request；
Wherein, common recognition node is divided according to computer room, is same cluster by the common recognition node division of same computer room, often
The main common recognition node of one cluster configuration one and at least one spare common recognition node.
Wherein, if not receiving what the main common recognition node of at least one of other clusters was sent within scheduled first time
It is abnormal then to illustrate that the computer room occurs for confirmation message, which may be that main common recognition node delay machine is also likely to be entire computer room delay machine.
It, then can be again to not receiving confirmation message pair in order to confirm that the exception is main common recognition node delay machine or entire computer room delay machine
The main common recognition node for the cluster answered sends heartbeat request, for example, every the heartbeat request of transmission in 10 seconds to these clusters
Main common recognition node, if there is heartbeat response, main common recognition node is worked normally, can be in limiting time if main common recognition node delay machine
Interior (for example, 1 minute) elects a certain spare common recognition node in this cluster as main common recognition node, during this, can not receive the heart
After jump responds, but the spare common recognition node of follow-up election is as temporary main common recognition node, it is able to carry out heartbeat response, can be confirmed
The main common recognition node delay machine of the cluster.
The enabling module 102, if for not received within scheduled second time (i.e. more than election time threshold)

The synchronous increment block data of the main common recognition node of group.After synchronously completing, the main common recognition node of the cluster to resume operation is online total
Know service.
As shown in figure 4, Fig. 4 is the flow diagram of one embodiment of the method for the present invention, the processor 13 of electronic device 1 is executed
The following steps of this method are realized when the processing system 10 stored in memory 12:
Step S1, when the main common recognition node in cluster completes block, the respectively main common recognition section into other clusters in common recognition
After point sends the confirmation request for completing the block of whether knowing together, asked if not received within scheduled first time based on the confirmation
Corresponding confirmation message is sought, then sends heartbeat request to the main common recognition node for not receiving the corresponding cluster of confirmation message；
Wherein, common recognition node is divided according to computer room, is same cluster by the common recognition node division of same computer room, often
The main common recognition node of one cluster configuration one and at least one spare common recognition node.
Wherein it is possible to carry out the common recognition of block using Paxos, Raft or PBFT scheduling algorithm.
If (for example, 5 minutes) receive the transmission of the main common recognition node in other clusters within scheduled first time
Confirmation message, illustrate this block common recognition success, block data after common recognition can be committed to back end.If pre-
The confirmation message that the main common recognition node of at least one of other clusters is sent is not received in fixed first time, then illustrates the computer room
There is exception, which may be that main common recognition node delay machine is also likely to be entire computer room delay machine.In order to confirm that the exception is main total
Know node delay machine or entire computer room delay machine, then it can be again to the main common recognition node for not receiving the corresponding cluster of confirmation message
Heartbeat request is sent, for example, sending a heartbeat request every 10 seconds to the main common recognition node of these clusters, if there is heartbeat to ring
It answers, then main common recognition node works normally, if main common recognition node delay machine, (for example, 1 minute) can elect this collection within a limited period of time
A certain spare common recognition node in group is as main common recognition node, during this, can not receive heartbeat and respond, but follow-up election is spare total
After knowing node as temporary main common recognition node, it is able to carry out heartbeat response, the main common recognition node delay machine of the cluster can be confirmed.
Step S2 is responded if not receiving the cluster within scheduled second time based on the heartbeat of the heartbeat request,
Computer room delay machine occurs for the cluster for not carrying out heartbeat response, enables the spare common recognition node in this cluster as generation computer room delay machine
The main common recognition node of cluster carry out common recognition service, to know together to block；
If (such as 3 minutes) are not received the cluster and are rung based on the heartbeat of the heartbeat request within scheduled second time
It answers, that is, is more than election time threshold, it is believed that computer room delay machine, i.e. this computer room all devices are damaged, such as earthquake, fire occurs
Entire computer room damages when calamity, then enables the spare common recognition node in this cluster as the cluster that computer room delay machine occurs
Temporary main common recognition node, carries out common recognition service.
Step S3 closes conduct after receiving the recovery message resumed operation that the collection pocket transmission of computer room delay machine occurs
The common recognition service of the spare common recognition node of the main common recognition node of the cluster to resume operation, and control the spare common recognition node and be somebody's turn to do
The synchronous increment block data of the main common recognition node of the cluster to resume operation.
Wherein, it after delay machine computer room restores to operate normally, sends restore to the main common recognition node of other each computer rooms respectively
After the main common recognition node of other each computer rooms receives the recovery message, the recovered normal fortune of the computer room is can be confirmed in message
Row.For enabling machine of the spare common recognition node in this cluster as the temporary main common recognition node for the cluster that computer room delay machine occurs
Room, after receiving recovery message, due to the common recognition service for the main common recognition node for no longer needing this temporary, this is temporary
The common recognition service of main common recognition node is closed.Then, the cluster by controlling the temporary main common recognition node with resuming operation
The synchronous increment block data of main common recognition node, the block data of the main common recognition node of the cluster to resume operation is updated to most
The state of new block data.After synchronously completing, the online common recognition service of the main common recognition node of the cluster to resume operation.
Wherein, in synchronous increment block data, the data synchronizing function of Kafka can be used, by Kafka to computer room
(rack) it completes to synchronize with the configuration of the node of synchronous increment block data (insync replica).
It further,, should after the main common recognition node in cluster synchronizes increment block data after above-mentioned step S3
Method further include: whether main common recognition node into other clusters sends to know together and complete the confirmation of the increment block data and ask respectively
It asks；If the confirmation message that the main common recognition node in other clusters is sent based on the confirmation request is received, by the increment area
Block number is according to the back end being synchronized in block chain.
Further, when the main common recognition node in cluster receives the whether total of the transmission of the main common recognition node in other clusters
After knowing the confirmation request for completing a block, analyze in the newest block number and other clusters of the main common recognition node in this cluster
Whether the newest block number of main common recognition node is consistent；
If the newest block number of the main common recognition node in this cluster is less than the newest of the main common recognition node in other clusters
Block number, then the main common recognition node into other clusters requests increment block data；
If the newest block number of the main common recognition node in this cluster is greater than the newest of the main common recognition node in other clusters
Block number, then main common recognition node into other clusters sends confirmation request, for the main common recognition node in other clusters to
Main common recognition node in this cluster requests increment block data.
Wherein, if the block number of the newest block of the main common recognition node in each cluster is consistent, i.e., it is believed that each
Block in a cluster is synchronized to last state.For example, if the newest block number of the main common recognition node in this cluster is
100, the newest block number of the main common recognition node in other clusters is 103, then the main common recognition node in this cluster is needed to it
The corresponding increment block data of block number that main common recognition node request block number in his cluster is 101 to 103；If this
The newest block number of main common recognition node in cluster is 103, and the newest block number of the main common recognition node in other clusters is
100, then the main common recognition node in this cluster needs the main common recognition node into other clusters to send confirmation request, for other collection
It is 101 to 103 block number that main common recognition node in group, which requests the block block number to the main common recognition node in this cluster,
Corresponding increment block data.
In one embodiment, on the basis of the above embodiments, after above-mentioned steps S1, this method further include: when having
