In a second aspect, an embodiment of the present invention provides a data backup migration method.
Referring to fig. 2, fig. 2 is a flowchart illustrating a data backup migration method according to an embodiment of the present invention.
In an embodiment of the data backup migration method of the present invention, the data backup migration method includes:
step S10, detecting whether the first automobile driving recorder number has a mapping relation with the vehicle identification code;
in this embodiment, the first vehicle driving recorder is a new vehicle driving recorder, the second vehicle driving recorder is an old vehicle driving recorder, and the vehicle identification code is a vehicle number of the vehicle driving recorder that needs to be replaced. In order to realize that the data of the old automobile driving recorder can be automatically recorded when the new automobile driving recorder is switched by the automobile and complete the data migration, whether the serial number of the first automobile driving recorder has a mapping relation with the vehicle identification code or not needs to be determined firstly so as to judge whether the automobile driving recorder does not have the mapping relation with the vehicle identification code or has the mapping relation with the vehicle identification code. And only on the premise of determining that the mapping relation exists, uploading the local storage data of the automobile driving recorder which is not subjected to the first-time mapping relation and corresponds to the vehicle identification code to a file backup cloud server to complete the backup of the driving data, and importing the storage data in the file backup cloud server into the automobile driving recorder which is subjected to the first-time mapping relation and corresponds to the vehicle identification code to complete the migration of the driving record data backup.
Further, referring to fig. 3, in an embodiment, before step S10, the method includes:
step S01, performing authority verification according to the key corresponding to the first automobile driving recorder number;
and step S02, after the authority verification is passed, executing the step of detecting whether the first automobile driving recorder number has a mapping relation with the vehicle identification code.
In this embodiment, before the step of detecting whether the first vehicle travel recorder number has a mapping relationship with the vehicle identification code, authority verification needs to be performed based on a secret key corresponding to the first vehicle travel recorder number, when the secret key is that the vehicle travel recorder leaves a factory, the tool detection device automatically generates the secret key according to the unique code number of the vehicle travel recorder, and the generated secret key is automatically introduced into the file backup cloud server and the vehicle travel recorder and is used for performing identity verification on the vehicle travel recorder performing data backup and migration, so that data in the file backup cloud server is prevented from being tampered by external equipment with unknown identity. Therefore, after the authority verification is passed, the step of detecting whether the first automobile driving recorder number has the mapping relation with the automobile identification code is executed, and the data in the file backup cloud server cannot be tampered and lost, so that the follow-up analysis and supervision based on the data are influenced.
Step S20, if the vehicle identification code has no mapping relation with the first automobile running recorder number but has mapping relation with the second automobile running recorder number, the second mapping relation between the vehicle identification code and the second automobile running recorder number is released, and a first mapping relation between the vehicle identification code and the first automobile running recorder number is established;
in this embodiment, if the vehicle id does not have a mapping relationship with the first vehicle travel recorder number but has a mapping relationship with the second vehicle travel recorder, it indicates that the vehicle id has a mapping relationship with the old vehicle travel recorder, and at this time, the data stored in the old vehicle travel recorder in the file backup cloud server can be imported into the new vehicle travel recorder after the mapping relationship with the old vehicle travel recorder is first released and then the mapping relationship with the new vehicle travel recorder is established. If the vehicle identification code is monitored not to have a mapping relation with the number of the first automobile running recorder but has a mapping relation with the number of the second automobile running recorder, the second mapping relation between the vehicle identification code and the number of the second automobile running recorder is released, and the first mapping relation between the vehicle identification code and the number of the first automobile running recorder is established. The mapping relation between the vehicle identification code and the vehicle driving recorder is used as a data interaction condition for guaranteeing the vehicle driving recorder and the file backup cloud server, so that data can be interacted in the direction corresponding to the mapping relation, and data error interaction is avoided.
Further, referring to fig. 4, in an embodiment, the step S20 includes:
step S201, if the vehicle identification code does not have a mapping relation with the first vehicle running recorder number but has a mapping relation with the second vehicle running recorder number, when a request for deleting the second mapping relation between the vehicle identification code and the second vehicle running recorder number is received, determining whether the information to be verified contained in the request is legal or not;
step S202, if the information to be verified contained in the request is legal, the second mapping relation between the vehicle identification code and the serial number of the second automobile driving recorder is released, and the first mapping relation between the vehicle identification code and the serial number of the first automobile driving recorder is established.
In this embodiment, if the vehicle id does not have a mapping relationship with the first vehicle travel recorder number but has a mapping relationship with the second vehicle travel recorder number, the mapping relationship with the old vehicle travel recorder needs to be released at this time, and then the mapping relationship with the new vehicle travel recorder needs to be established, so that the data stored in the old vehicle travel recorder in the file backup cloud server can be imported into the new vehicle travel recorder. Before changing the mapping relationship between the vehicle identification code and different automobile driving recorders, it is necessary to determine whether the information to be verified included in the request is legal or not when receiving a request for deleting the second mapping relationship between the vehicle identification code and the serial number of the second automobile driving recorder. And under the condition that the information to be verified contained in the request is legal, the second mapping relation between the vehicle identification code and the serial number of the second automobile driving recorder is removed, and the first mapping relation between the vehicle identification code and the serial number of the first automobile driving recorder is established, so that the mapping relation between the vehicle identification code and different automobile driving recorders cannot be changed randomly by illegal equipment, and the accuracy of data backup and migration is influenced.
Step S30, extracting the vehicle parameters and the driving record data corresponding to the vehicle identification code from the file backup cloud server, and updating the vehicle parameters and the driving record data into a first vehicle driving recorder corresponding to the first vehicle driving recorder number based on the first mapping relationship.
In this embodiment, the first mapping relationship between the vehicle id code and the first vehicle driving recorder number is established only after the second mapping relationship between the vehicle id code and the second vehicle driving recorder number is released. Therefore, before the first mapping relation is established, when the second mapping relation exists, the vehicle parameters and the driving record data corresponding to the vehicle identification codes backed up from the second automobile driving recorder are also stored in the file backup cloud server. After the first mapping relationship is established, the vehicle parameters and the driving record data corresponding to the vehicle identification code can be extracted from the file backup cloud server, and are updated to the first automobile driving recorder corresponding to the first automobile driving recorder number based on the first mapping relationship. The mode of backing up and transferring the corresponding vehicle parameters and the driving record data from the file backup cloud server is simple and efficient, the risk of data entry errors is reduced, the cost of after-sale maintenance is reduced, and historical driving record data can be kept to serve as effective basis for law enforcement.
Further, referring to fig. 5, in an embodiment, after the step S10, the method includes:
step S40, if the vehicle identification code and the first automobile driving recorder number have a first mapping relation, packaging vehicle parameters and driving record data stored by the first automobile driving recorder corresponding to the first automobile driving recorder number as a target backup file, and calculating to obtain a first MD5 value based on the target backup file;
step S50, acquiring a second MD5 value corresponding to the backed-up file of the vehicle identification code in the file backup cloud server;
step S60, comparing the first MD5 value with the second MD5 value;
step S70, if the first MD5 value is not equal to the second MD5 value, uploading the target backup file and the corresponding first MD5 value to the file backup cloud server based on the first mapping relationship, so as to overwrite the backed-up file and the corresponding second MD5 value.
In this embodiment, if it is detected that the first vehicle-driving recorder number has a mapping relationship with the vehicle identification code, it indicates that the first vehicle-driving recorder does not establish a mapping relationship with the vehicle identification code for the first time. Therefore, the vehicle parameters and the driving record data corresponding to the vehicle identification code do not need to be extracted from the file backup cloud server to perform migration of the backup file, but whether newly added vehicle parameters and driving record data exist in the first automobile driving recorder is judged to judge whether the backup file needs to be updated, and the newly added vehicle parameters and the driving record data are also backed up to the file backup cloud server.
Therefore, if the vehicle identification code and the first automobile driving recorder number have the first mapping relation, the vehicle parameters and the driving record data stored by the first automobile driving recorder corresponding to the first automobile driving recorder number are packed to be used as target backup files, and then the backup files of the vehicle identification code in the file backup cloud server are compared with the target backup files to judge whether the backup files in the file backup cloud server need to be updated or not. If the contents of the backed-up file and the target backed-up file are directly compared, the flow and the network bandwidth are occupied when the file contents are more and the file volume is larger. Therefore, in this embodiment, MD5 values of the backed-up file and the target backed-up file are calculated respectively, and then compared based on the MD5 value, which occupies less traffic and network bandwidth, and the speed of comparing files is faster. And performing MD5 verification on each byte in the file to generate a corresponding character until the last byte, so as to obtain an MD5 value corresponding to the whole file. If the MD5 values corresponding to the two files are the same, the contents of the two files are the same.
Thus, after packaging the target backup file, a first MD5 value may be calculated based on the target backup file. And acquiring a second MD5 value corresponding to the backed-up file of the vehicle identification code in the file backup cloud server. And comparing the first MD5 value with the second MD5 value, and if the first MD5 value is not equal to the second MD5 value, indicating that newly added vehicle parameters and running record data exist in the first automobile running recorder at the moment. At this time, the target backup file and the corresponding first MD5 value are uploaded to the file backup cloud server based on the first mapping relationship to overwrite the backed-up file and the corresponding second MD5 value, and update of the vehicle parameters and the driving record data corresponding to the vehicle identification code in the file backup cloud server is completed. The method can ensure that the data contents in the automobile driving recorder and the file backup cloud server are not repeated and omitted, and the accuracy of the backup files is ensured.
Further, in an embodiment, after step S60, the method includes:
if the first MD5 value is equal to the second MD5 value, the backed-up file of the vehicle identification code and the corresponding second MD5 value in the file backup cloud server are not updated.
In this embodiment, if the value of the first MD5 is equal to the value of the second MD5, it indicates that there are no new vehicle parameters and no new driving record data in the first vehicle driving recorder at this time. And at the moment, the backed-up file of the vehicle identification code and the corresponding second MD5 value in the file backup cloud server are not updated.
Further, in an embodiment, the vehicle parameter and the driving record data include: the vehicle identification code corresponds to a motor vehicle number plate number, a motor vehicle number plate classification, a motor vehicle type, a provincial domain ID, a city domain ID, network access information, a networking authentication code, a vehicle pulse coefficient and a vehicle driving data record.
In this embodiment, the vehicle parameters and the driving record data corresponding to the vehicle identification code that need to be obtained from the automobile driving recorder include: the vehicle identification code corresponds to a motor vehicle number plate number, a motor vehicle number plate classification, a motor vehicle type, a provincial domain ID, a city domain ID, network access information, a networking authentication code, a vehicle pulse coefficient and a vehicle driving data record. The attribution and the vehicle type of the vehicle corresponding to the vehicle identification code can be obtained based on the number plate number of the motor vehicle, the motor vehicle number plate classification, the motor vehicle type, the provincial domain ID and the city domain ID. Based on the network access information and the networking authentication code, the access domain name, the port and the access authority parameters of the national freight monitoring platform and the vehicle manufacturer monitoring platform can be obtained. The real vehicle speed of the vehicle can be accurately converted based on the vehicle pulse coefficient, so that the subsequent speed information record in normal running is facilitated. Whether the vehicle has illegal driving behaviors such as fatigue driving or overspeed driving can be obtained based on the vehicle driving data record, and information including the starting time, the ending time, the longitude, the latitude and the like of the illegal driving behaviors such as fatigue driving or overspeed driving can be obtained at the same time, and the information can be used as a reliable law enforcement basis for law enforcement departments.
