As shown in fig. 4, in some embodiments, the process of comparing user data of adjacent time points on the time axis may include steps S410 to S420, which are described in detail as follows:
s410, taking any time point as a current time point on a time axis, and acquiring a previous time point adjacent to the current time point;
in step S410, the current time point is a next time point, and the present embodiment determines whether the user data at a next time point of the next time point is rising or falling by comparing the user data at a next time point of the next time point with the user data at a previous time point of the next time point.

In step S420, since the user data includes the digital key download rate, the digital key activation rate, the digital key usage rate, and the digital key management tool login rate, the digital key download rate, the digital key activation rate, the digital key usage rate, and the digital key management tool login rate at the current time point need to be compared with the digital key download rate, the digital key activation rate, the digital key usage rate, and the digital key management tool login rate at the previous time point in order.
In some embodiments, when the difference value of the user data at the adjacent time point exceeds the preset threshold, the process of analyzing the change cause of the user data in combination with the event information corresponding to the next time point at the adjacent time point may include step S510, which is described in detail as follows:
s510, analyzing the change reason of the user data in combination with event information corresponding to a time point subsequent to the adjacent time point when one of the following conditions exists, wherein the following conditions include:
the difference value between the digital key downloading rate of the previous time point of the adjacent time point and the digital key downloading rate of the next time point exceeds a preset first threshold value;
the difference between the digital key activation rate of the previous time point and the digital key activation rate of the next time point exceeds a preset second threshold;
the difference between the digital key usage rate of the previous time point of the adjacent time point and the digital key usage rate of the next time point exceeds a preset third threshold;
the difference between the digital key management tool registration rate at the previous time point of the adjacent time point and the digital key management tool registration rate at the next time point exceeds a preset fourth threshold.
In step S510, when any item of user data at a time point subsequent to the adjacent time point falls more than the user data at a time point prior to the adjacent time point, it is indicated that the user data of the digital key falls. Therefore, it is necessary to analyze event information at a time point immediately before an adjacent time point, and the cause of the decline in the user data is obtained by analyzing the event information.
In some embodiments, the event information includes digital key management tool update information, user feedback information;
analyzing the change reason of the user data in combination with event information corresponding to the later time point of the adjacent time points to obtain an analysis result, wherein the analysis result comprises one or more of the following four situations:
(1) When the difference value between the digital key downloading rate of the previous time point and the digital key downloading rate of the next time point exceeds a preset first threshold value, and the digital key management tool updating information or the user feedback information of the next time point of the adjacent time points comprises information related to digital key downloading, judging that factors to be improved exist in the downloading mode of the digital key;
specifically, in this embodiment, the digital key is downloaded from the cloud through the digital key management tool, so if the downloading rate of the digital key is reduced more, it is indicated that there is a disorder to the operation of downloading the digital key in the newly added user, which may cause the disorder of downloading the digital key, for example: the download key of the download page is hidden, the user mobile phone does not open the trust function, the download channel is jammed, and the like; the reasons for the descent can be determined by combining the update information of the digital key management tool and the user feedback information.
(2) When the difference value between the digital key activation rate of the previous time point and the digital key activation rate of the next time point exceeds a preset second threshold value, and the digital key management tool update information or the user feedback information of the next time point comprises information related to the digital key activation, judging that factors to be improved exist in the activation mode of the digital key;
specifically, in this embodiment, the digital key is activated by the digital key management tool, so if the activation rate is reduced, it can be presumed that the reason that the activation button of the activation page in the management tool is hidden, the trust function is not opened by the mobile phone of the user, and the reduction reason can be determined by combining the update information of the digital key management tool and the feedback information of the user;
(3) When the difference value between the digital key utilization rate of the previous time point and the digital key utilization rate of the next time point exceeds a preset third threshold value, and the digital key management tool updating information or the user feedback information of the next time point of the adjacent time points comprises information related to the digital key utilization, judging that the utilization mode of the digital key has factors to be improved;
specifically, in this embodiment, the digital key is used by the digital key management tool, so if the usage rate is reduced, it can be presumed that the reasons such as the use button of the use page in the management tool is hidden, the user mobile phone does not start the trust function, and the reduction reason can be determined by combining the update information of the digital key management tool and the user feedback information;
(4) When the difference between the login rate of the digital key management tool at the previous time point and the login rate of the digital key management tool at the next time point exceeds a preset fourth threshold value, and the update information or the user feedback information of the digital key management tool at the next time point of the adjacent time points has information related to the login of the digital key management tool, judging that the login mode of the digital key management tool has factors to be improved.
Specifically, in this embodiment, the digital key is downloaded, activated and used by the digital key management tool, and if the login rate of the digital key management tool is reduced, the download rate, activation rate and use rate of the digital key are likely to be affected. When the login rate is reduced, the reasons of complicated login process, complicated checking process and the like can be presumed, and the solution mode can be to add a one-key login function.
The specific implementation process is as follows:
(1) Obtaining data, namely obtaining a digital key downloading rate, a digital key activation rate, a digital key use rate and a digital key management tool login rate after obtaining, preprocessing (such as de-duplication) and calculating the original data;
(2) Analyzing trend, wherein user growth is kept stable within two months, and hot car models are kept high;
(3) Finding out an abnormal point, verifying that the download rate of the digital key is reduced within 30 days, and knowing that the download rate is reduced due to a certain reason before 30 days;
(4) The reason analysis, through the record analysis of the real-name login user, finds that in the real-name authentication of the user who has login inCallApp (management consolidation) but does not download the Bluetooth key, the user clicks the 'discard open' function, and the user clicks the 'discard open' function at the second step, so that the number of users is the largest. In the 'click discard on' function user, there is a ratio of 2/3 device switches, which means that the switching of the devices may have some influence on the user 'click discard on'. The associated user feedback list in the 'click discard open' user finds that the user looking at the 'discard open' user on the same day and consulting the bluetooth key problem on the same day has the problem that the 'cannot be opened after the machine is refreshed', which means that the system update can cause the user to 'click discard open'.
