Description

Technical Field

[0001] The present invention relates to the technical field of computer storage, and particularly to a distributed mutual backup and recovery system for battery detection equipment. Background Art

[0002] Common methods of current computer file backup software are as follows: 1) Compress the files and directories to be backed up into a single compressed package of types such as zip and rar, or directly copy another copy. The disadvantage of this method is that the disk space occupied after backup is very large because the exactly same files will be saved multiple times each time of backup; 2) The single-machine version of backup software saves the backup to the local computer. The disadvantage of this method is that once the computer hard disk is damaged (irreparable), the files and backups will all be lost; 3) The single-machine version of backup software saves the backup to storage devices such as USB flash drives and external hard drives. The disadvantage of this method is that it is very troublesome to manually insert the USB flash drive and external hard drive into the computer each time of backup; 4) The local area network version of backup software saves the backup to the server set up by the company itself. The disadvantages of this method are high costs (the price of purchasing a professional server is very high, and the cost of setting up its own cloud server is even higher), and there is also a risk that the service hard disk of the non-cloud server is damaged (irreparable), and the backup will all be lost, and the server requires special maintenance; 5) The wide area network version of backup software saves the backup to the cloud storage server of other companies. The disadvantages of this method are slow transmission speed due to Internet speed reasons, and it cannot prevent the cloud storage service company from viewing private files.

[0003] Battery detection is a key link to ensure battery performance. With the rapid development of new energy, the application field of batteries is becoming more and more extensive. Batteries need to be tested in various extremely complex environments, which not only requires a high sampling frequency but also a long-time test. A large amount of test data is generated during the test. Since these test data can well reflect the battery condition, the security of the test data is very important. Due to long-time high-frequency sampling, the amount of test data is very large, but most of these data are saved on the computer disk. During the data storage process, frequent writing to the disk is likely to cause disk damage, resulting in serious accidents of loss of test data, and in actual applications, data is accidentally deleted due to improper operation and not discovered in time, resulting in inability to recover later, and the anti-risk ability of test data is weak. Summary of the Invention

[0004] The purpose of the present invention is to provide a novel distributed mutual backup and recovery system for battery detection equipment to solve the deficiencies of the above technical problems. During the testing process, it can reduce the risk of data loss. The test data will form redundant backups on multiple computers within the local area network. The dispersed storage of backup data between different computers effectively avoids the impact brought by single-point failures and provides a more powerful data security guarantee. It supports the data recovery function. When users encounter data loss or failures, they can quickly recover through the backup data, and reduce the risks brought by the loss or damage of test data to ensure the smooth progress of the testing work.

[0005] The present invention is realized through the following technical solutions: A distributed mutual backup and recovery system for battery detection equipment, including a human-computer interaction interface, a control module, a network communication module, a data backup module, and a data recovery module. The human-computer interaction interface is signal-connected to the control module, and the control module is respectively signal-connected to the network communication module, the data backup module, and the data recovery module. When the user performs a data recovery operation through the human-computer interaction interface, the human-computer interaction interface sends the data recovery operation to the control module. The control module executes the task of restoring data through the data recovery module and displays the real-time process status processed by the data recovery module on the human-computer interaction interface.

[0006] As a further step, assume that there are N + 1 (N > 0) computers connected by Ethernet or wireless network within a local area network. Each computer is equipped with a distributed mutual backup and recovery system, and at the same time, the computer is also equipped with a client, a server, and a database of a battery detection device; the user number A represents the distributed mutual backup and recovery system of the local computer, and the user numbers B1 - BN represent the distributed mutual backup and recovery systems of non-local computers within the local area network. The user number B represents one or more distributed mutual backup and recovery systems obtained from the user numbers B1 - BN according to the screening conditions. The screening conditions include that the software information "the number of already backed up" is less than "the number of to be backed up" or the backup record contains the software information. The backup record includes software information and several test data information; the user number C represents one or more distributed mutual backup and recovery systems that have performed backup tasks on the user number A obtained from the user numbers B1 - BN. The user number A communicates with the user numbers B1 - BN through their respective network communication modules; after the user number A is started, the network communication module of the user number A generates the software information of the user number A and obtains the software information of the user numbers B1 - BN. The software information includes the number of already backed up and the number of to be backed up; the control module of the user number A regularly establishes a backup task for the user number B. The user number A executes the backup task for the user number B through the data backup module, and displays the backup status processed by the data backup module on the human - machine interface of the user number A; the user performs a data recovery operation through the human - machine interface of the user number A. The human - machine interface of the user number A sends the data recovery operation to the control module of the user number A. The control module of the user number A executes the data recovery task through the data recovery module of the user number A and displays the real - time process status processed by the data recovery module on the human - machine interface of the user number A.

[0007] As a further step, the control module executes real - time commands operated by the user through the human - machine interface. The real - time commands include an execute data recovery command and a save parameter setting command: For the execute data recovery command, the user clicks the search button for data recovery through the human - machine interface, obtains the backup record through the data recovery module. The backup record includes software information and several test data information. The backup record is displayed on the human - machine interface. The user selects several test data information to be recovered from it, clicks the start data recovery button, triggers the command to recover data, and the control module executes the data recovery task through the data recovery module and displays the real - time process status processed by the data recovery module on the human - machine interface; For the save parameter setting command, the user performs parameter setting through the human - machine interface. The parameter includes "the number of to be backed up". The control module saves the parameter setting and updates the software information "the number of to be backed up" of the local machine to the user - set value through the network communication module.

[0008] Further, the network communication module respectively establishes connections and interactions with the servers of the battery detection devices of user number A and user number B, and obtains the channels, test data files, and test information of the channels of the battery detection devices; the network communication module processes the sending and receiving of instructions, and the instructions include broadcast search instructions, broadcast real-time information instructions, start backup instructions, backup result instructions, obtain backup data file information instructions, download backup data file instructions, obtain recovery data file information instructions, and download recovery data file instructions; the network communication module generates software information and obtains the software information of user numbers B1 - BN; the network communication module updates the software information of user numbers B1 - BN in real time.

[0009] Further, the obtaining of the software information of user numbers B1 - BN includes the following steps: S1: User number A sends a broadcast search instruction to the local area network; S2: After receiving the broadcast search instruction, user numbers B1 - BN respectively send broadcast search response instructions to the local area network, and the broadcast search response instructions include software information; S3: User number A receives the broadcast search response instructions sent by user numbers B1 - BN in the local area network; S4: Analyze the broadcast search response instructions sent by B1 - BN to obtain the software information of user numbers B1 - BN.

[0010] Further, the real-time update of the software information of user numbers B1 - BN, and regularly sending broadcast real-time information instructions, includes the following steps: S1: User number A sends a broadcast real-time information instruction to the local area network; S2: After receiving the broadcast real-time information instruction, user numbers B1 - BN respectively send broadcast real-time information response instructions to the local area network, and the broadcast real-time information response instructions include software information; S3: User number A receives the broadcast real-time information response instructions sent by user numbers B1 - BN in the local area network; S4: Analyze the broadcast real-time information response instructions sent by B1 - BN to update the software information of user numbers B1 - BN.

[0011] Further, user number A performs the backup task of user number B through the data backup module, including the following steps: S1: User number A sends a start backup instruction to user number B; S2: After receiving the start backup instruction, user number B determines whether the "number of already backed up" of the local software information is less than the "number of required backups". If so, proceed to the next step; if not, user number B sends a result of no need to backup to user number A and executes step S9; S3: User B with user ID sends the result to be backed up to User A with user ID, and increments the "number of items already backed up" in the software information of its own device by one. S4: User A with user ID obtains the backup record and sends the backup status to the control module for display on the human-machine interface. S5: Traverse the channels of the battery detection device of User B with user ID, obtain the test information of the last test of the channel, and determine whether the backup record already contains the test information of the last test of the channel and the last test has been completed. If so, skip it; if not, execute the sub-process of backing up single test data according to the test information of the last test of the channel. S6: Traverse the channels of the battery detection device of User B with user ID, obtain the test information of other tests of the channel except the last test, and determine whether the backup record already contains this test information. If so, skip this test information; if not, execute the sub-process of backing up single test data according to the test information. S7: User A with user ID sends a backup result instruction to User B with user ID and saves the backup record. User A with user ID sends the backup status to the control module for display on the human-machine interface. S8: After User B with user ID receives the backup result instruction, the data recovery module of User B with user ID saves the record to be backed up. S9: Backup ends.

[0012] As a further step, the sub-process of backing up single test data includes the following steps: S1: User A with user ID sends an instruction to User B with user ID to obtain backup data file information. S2: After User B with user ID receives the instruction to obtain backup data file information, it obtains the test data file through the network communication module of its own device and sends the information of the test data file to User A with user ID. S3: User A with user ID sends an instruction to User B with user ID to download the backup data file according to the information of the test data file. After User B with user ID receives the instruction to download the backup data file, it obtains the content of the test data file through the network communication module of its own device, sends the content of the test data file to User A with user ID, and User A with user ID saves the backup data file. S4: The process ends.

[0013] As a further step, when obtaining the record to be backed up through the data recovery module, when User C with user ID executes the backup task for User A with user ID and saves the record to be backed up after receiving the backup result instruction of User C with user ID; the data recovery module executes the data recovery task, traversing several pieces of test data information to be recovered. Each piece of test data information to be recovered includes the following steps when executing the recovery: S1: User A sends a command to obtain recovery data file information to User C. S2: After receiving the command to obtain recovery data file information, User C retrieves the backup data file from the data backup module and sends the information of the backup data file to User A. S3: User A sends a command to download the recovery data file to User C based on the information of the backup data file. After receiving the command to download the recovery data file, User C retrieves the content of the backup data file through the local backup data module and sends the content of the backup data file to User A, and User A saves the recovery data file. S4: Send the real-time process status of the recovery data to the control module, and the process ends.

[0014] The beneficial effects of the present invention are as follows: During the testing process, the risk of data loss can be reduced, and the test data will form redundant backups in multiple computers within the local area network; the dispersed storage of backup data between different computers effectively avoids the impact of single-point failures and provides a more powerful data security guarantee; it supports the data recovery function. When users encounter data loss or failures, they can quickly recover through the backup data, and reduce the risk caused by the loss or damage of test data, ensuring the smooth progress of the testing work.
