[0032] The following will be combined with the drawings in this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] Example 1, see Figure 1 , Figure 1 : is a flow chart of an embodiment of a data difference comparison method provided in an embodiment of the present application, such as Figure 1 As shown, the method includes steps 101 and 102, which are specifically as follows:

[0034] Step 101: respectively obtain the first configuration data file and the second configuration data file stored in the first file path and the second file path of the target application; wherein, the first configuration data file is the file stored in the first file path after the target application receives the first broadcast signal, and the first configuration data file is the file obtained before the version OTA upgrade; the second configuration data file is the file stored in the second file path after the target application receives the second broadcast signal, and the second configuration data file is the file obtained after the version OTA upgrade.

[0035] In an embodiment of the present application, the first broadcast signal is generated by monitoring a selection operation on a first target object. When a selection operation on the first target object is monitored, the selection operation is responded to and a first broadcast signal corresponding to the first target object is generated, wherein the first broadcast signal carries a first file path.

[0036] Preferably, the first target object is a data acquisition object before version OTA upgrade; the first target object may exist in the form of a button that can be triggered or clicked on a display device.

[0037] Preferably, when monitoring the selection operation on the first target object, the hovering operation of the mouse arrow may be monitored. When it is detected that the mouse arrow hovers over the first target object area and a mouse click event occurs, it is determined that the first target object is selected.

[0038] Preferably, when generating the first broadcast signal corresponding to the first target object, the corresponding first file path is determined based on the first target object, and based on the set data capture application, a broadcast action is set for the generated first broadcast signal, and the first file path is added to the first broadcast signal as additional data so that the first broadcast signal carries the first file path.

[0039] Preferably, the first file path is a file path used to store data before version OTA upgrade.

[0040] In an embodiment of the present application, after the first broadcast signal is generated, the first broadcast signal is also sent to the target application, and when the first broadcast signal is sent, a permission parameter is added to the first broadcast signal so that the target application identifies whether to receive the first broadcast signal based on the permission parameter.

[0041] Preferably, permission parameters are added to the first broadcast signal by declaring permissions in the Android application manifest file AndroidManifest.xml and setting permissions when sending a broadcast, and based on the permission parameters, it can be determined which applications can receive the broadcast.

[0042] In an embodiment of the present application, before receiving the first broadcast signal, the target application also includes: obtaining the broadcast permission corresponding to the first broadcast signal, comparing the broadcast permission with the target application permission corresponding to the target application, and when it is detected that the broadcast permission matches the target application permission, controlling the target application to receive the first broadcast signal; wherein, the target application permission is obtained by the target application through static registration broadcast registration, and the broadcast permission is the permission parameter set when the first broadcast signal is sent.

[0043] Preferably, the target application permissions corresponding to the target application are permissions declared when registering the broadcast receiver by statically registering the broadcast. This permission also needs to be declared in advance in the Android application manifest file AndroidManifest.xml, and signature permissions are added.

[0044] Preferably, if the broadcast permission of the first broadcast signal matches the target application permission declared when the target application statically registers the broadcast receiver, the system allows the target application to receive the first broadcast signal. If the permissions do not match, the system prevents the target application from receiving the first broadcast signal.

[0045] By declaring broadcast permissions, you can limit which applications can send specific broadcasts and which applications or components can receive the broadcasts. This permission control ensures that data can only be processed by applications with corresponding permissions, preventing unauthorized applications from receiving sensitive data or performing unauthorized operations, thereby enhancing data security.

[0046] In an embodiment of the present application, the target application includes a large-screen application in a vehicle's onboard screen, wherein the large-screen application includes but is not limited to vehicle control, system settings, music and other applications.

[0049] In the embodiment of the present application, when it is detected that the first file path exists and no data file exists under the first file path, the target application obtains and stores the first configuration data file under the first file path.

[0050] In an embodiment of the present application, when it is detected that the first file path exists and a data file exists under the first file path, the data file is cleared, and the target application obtains and stores the first configuration data file under the first file path.

[0051] In the embodiment of the present application, when it is detected that the first file path does not exist, the target application creates the first file path, obtains and stores the first configuration data file in the first file path.

[0052] Preferably, when the target application obtains the first configuration data file, the first configuration data corresponding to the target application is obtained, and the first configuration data file is generated based on the first configuration data. The current time is obtained as a timestamp, and splicing processing is performed based on the target application name and the timestamp to obtain the first configuration data file name corresponding to the first configuration data file.

[0053] In the example, the target application name is CarControl, the timestamp is year-month-day-hour-minute-second, and the first configuration data file name is CarControl_year-month-day-hour-minute-second based on the concatenation processing of the target application name and the timestamp.

[0054] Preferably, the first configuration data is application setting data of the target application before the version OTA upgrade, which is one or more setting data that need to be obtained and is set in advance based on user needs, and the setting data can be read from the memory of the target application or from the underlying signal; taking the target application as vehicle control as an example, the first configuration data can be the setting value of the driving mode before the version OTA upgrade.

[0055] Preferably, the number format of the first configuration data is json format, and is written into the first configuration data file in a key-value manner; wherein, the value is of string type; this is because the value can be in the form of Boolean, integer or array, etc., and by uniformly converting them into string type, it can facilitate subsequent reading and display of data and avoid abnormal errors caused by data type conversion.

[0056] Preferably, when the existence of the first file path is detected, the first file path is combined with the first configuration data file name to obtain a first complete file path.

[0057] In example, the first file path is / sdcard / preOTA / , the target application name is CarControl, and the timestamp is year-month-day-hour-minute-second. Based on the target application name and the timestamp, the splicing processing is performed to obtain the data file name CarControl_year-month-day-hour-minute-second. The first file path is combined with the data file name to obtain the first complete file path / sdcard / preOTA / CarControl_year-month-day-hour-minute-second.txt; based on the first complete file path, it can be used to uniquely identify and locate a specific file.

[0058] Preferably, after obtaining the first complete file path, whether there is a data file under the first file path is determined by detecting whether the first complete file path exists; when it is detected that the first complete file path does not exist, it is determined that there is no data file under the first file path; when it is detected that the first complete file path exists, it is determined that there is a data file under the first file path.

[0059] Preferably, when it is detected that the first file path exists and no data file exists under the first file path, the target application stores the first configuration data file under the first complete file path by creating a first complete file path under the first file path.

[0060] Preferably, when it is detected that the first file path exists and no data file exists under the first file path, after clearing the data file, a first complete file path is created under the first file path, and the target application stores the first configuration data file under the first complete file path.

[0061] Preferably, when it is detected that the first file path does not exist, the target application first creates the first file path, creates a first complete file path under the first file path, and then obtains and stores the first configuration data file under the first file path.

[0062] Preferably, the first complete file path is the file path under the first file path; it can ensure that each target application has one and only one configuration data file under the first complete file path, and each configuration file is named with its corresponding target application name and the timestamp when it was written, ensuring that the configuration data written each time is the latest, and also facilitating subsequent viewing and comparison of the data.

[0063] In an embodiment of the present application, the second broadcast signal is generated by monitoring a selection operation on a second target object. When a selection operation on the second target object is monitored, the selection operation is responded to and a second broadcast signal corresponding to the second target object is generated, wherein the second broadcast signal carries a second file path.

[0064] Preferably, the second target object is a data acquisition object after version OTA upgrade; the second target object can exist in the form of a button that can be triggered or clicked on the display device.

[0065] Preferably, when monitoring the selection operation on the second target object, the hovering operation of the mouse arrow may be monitored.

[0067] Preferably, the second file path is a file path used to store data after the version OTA upgrade.

[0068] In an embodiment of the present application, after the second broadcast signal is generated, the second broadcast signal is also sent to the target application, and when the second broadcast signal is sent, a permission parameter is added to the second broadcast signal so that the target application identifies whether to receive the second broadcast signal based on the permission parameter.

[0069] In an embodiment of the present application, before receiving the second broadcast signal, the target application also includes: obtaining the broadcast permission corresponding to the second broadcast signal, comparing the broadcast permission with the target application permission corresponding to the target application, and when it is detected that the broadcast permission matches the target application permission, controlling the target application to receive the second broadcast signal; wherein, the target application permission is obtained by the target application through static registration broadcast registration, and the broadcast permission is the permission parameter set when the second broadcast signal is sent.

[0070] Preferably, if the broadcast permission of the second broadcast signal matches the target application permission declared when the target application statically registers the broadcast receiver, the system allows the target application to receive the second broadcast signal; if the permissions do not match, the system prevents the target application from receiving the second broadcast signal.

[0071] In an embodiment of the present application, the target application parses the received second broadcast signal to obtain a second file path.

[0072] Preferably, the target application obtains additional data by parsing a target field in the second broadcast signal, and obtains a second file path based on the additional data, wherein the target field is a path field.

[0073] In the embodiment of the present application, when it is detected that the second file path exists and no data file exists under the second file path, the target application obtains and stores the second configuration data file under the second file path.

[0074] In an embodiment of the present application, when it is detected that the second file path exists and there is a data file under the second file path, the data file is cleared, and the target application obtains and stores the second configuration data file under the second file path.

[0075] In the embodiment of the present application, when it is detected that the second file path does not exist, the target application creates the second file path, obtains and stores the second configuration data file in the second file path.

[0079] Preferably, when the existence of the second file path is detected, the second file path is combined with the second configuration data file name to obtain a second complete file path.

[0080] Preferably, after obtaining the second complete file path, whether there is a data file under the second file path is determined by detecting whether the second complete file path exists; when it is detected that the second complete file path does not exist, it is determined that there is no data file under the second file path; when it is detected that the second complete file path exists, it is determined that there is a data file under the second file path.

[0081] Preferably, when it is detected that the second file path exists and no data file exists under the second file path, the target application stores the second configuration data file under the second complete file path by creating a second complete file path under the second file path.

[0082] Preferably, when it is detected that the second file path exists and no data file exists under the second file path, after clearing the data file, a second complete file path is created under the second file path, and the target application stores the second configuration data file under the second complete file path.

[0083] Preferably, when it is detected that the second file path does not exist, the target application first creates the second file path, creates a second complete file path under the second file path, and then obtains and stores the second configuration data file under the second file path.

[0084] Preferably, the second complete file path is a file path under the second file path; it can be ensured that each target application has one and only one configuration data file under the second complete file path.

[0085] In an embodiment of the present application, when obtaining the first configuration data file and the second configuration data file stored in the first file path and the second file path of the target application, the selection operation acting on the third target object is monitored; when the selection operation acting on the third target object is monitored, the first configuration data file under the first file path is called, and the second configuration data file under the second file path is called at the same time.

[0086] Preferably, the third target object is an object for retrieving data before and after the version OTA upgrade; the third target object may exist in the form of a button that can be triggered or clicked on the display device.

[0087] Preferably, when monitoring the selection operation on the third target object, the hovering operation of the mouse arrow can be monitored. When it is detected that the mouse arrow hovers over the third target object area and a mouse click event occurs, it is determined that the third target object is selected.

[0088] Preferably, when generating the first broadcast signal corresponding to the first target object, the corresponding first file path is determined based on the first target object, and based on the set data capture application, a broadcast action is set for the generated first broadcast signal, and the first file path is added to the first broadcast signal as additional data so that the first broadcast signal carries the first file path.

[0089] Step 102: performing a data difference comparison between the first configuration data file and the second configuration data file to determine a data difference comparison result.

[0091] Preferably, for the target application, its corresponding configuration data may be one or more. To ensure that the same type of data to be compared can be quickly determined during subsequent data difference comparison, a preset sorting order is pre-set and based on the same preset sorting order, all the first configuration data in the first configuration data file and all the second configuration data in the second configuration data file are arranged respectively. This allows the first configuration data and the second configuration data corresponding to the same row in the arranged first configuration data column and the second configuration data column to be the same type of version data before and after OTA upgrade, and can be directly used for data difference comparison, thereby improving the efficiency of selecting comparison data.

[0092] Preferably, the preset arrangement order is the configuration data arrangement order obtained by arranging all configuration data corresponding to the target application based on user needs; since the first configuration data and the second configuration data are both written into the corresponding configuration data file in the form of key-value, the preset arrangement order can be sorted in the form of key value; for example, the preset arrangement order can be in the form of key1, key2, key3...keyn.

[0093] Preferably, the first key value corresponding to the first configuration data and the second key value corresponding to the second configuration data are the value values ​​of the corresponding configuration data; the value values ​​of the configuration data before and after the version OTA upgrade corresponding to the same key value can be directly determined through the target row.

[0095] In an embodiment of the present application, a data difference comparison is performed on the first configuration data and the second configuration data to obtain a data difference comparison result corresponding to the target row, by obtaining a first key value corresponding to the first configuration data, and simultaneously obtaining a second key value corresponding to the second configuration data; when it is detected that the first key value and the second key value satisfy a numerical consistency condition, the data difference comparison result corresponding to the target row is obtained, wherein the data difference comparison result is that the data is normal; or, when it is detected that the first key value and the second key value do not satisfy the numerical consistency condition, the data difference comparison result corresponding to the target row is obtained, wherein the data difference comparison result is that the data is abnormal.

[0096] Preferably, the numerical consistency condition is that the first key value is the same as the second key value.

[0097] Preferably, by directly comparing the first key value and the second key value corresponding to the target row, if they are inconsistent, it means that the data is abnormal and the data has been tampered with before and after the version OTA upgrade; if they are consistent, it means that the data is normal, and the data difference comparison result corresponding to the target row can be quickly determined.
