Description

Technical Field

[0001] The present application relates to the field of road safety technology, and in particular to a vehicle compliance analysis method and device based on data visualization. Background Art

[0002] The incidence of vehicle accidents is increasing year by year due to the driver's driving habits and other issues. Most vehicle accidents are often caused by the vehicle's speed being too high or too low. On current highways and other sections, due to the surrounding environment or road conditions, the speed of vehicles on a certain section of the road is required to be within a certain range. For example, a 20km section of road requires the speed to be below 80km / h to ensure surrounding safety, road safety and vehicle safety.

[0003] However, the general means of limiting the speed relies on calculating the average speed of the time when the vehicle enters the speed limit zone and the time when it leaves the speed limit zone. This often causes vehicle drivers to exceed the speed limit in a certain section of the speed limit zone. Finally, they stop and rest in the rest area to reduce the speed in the speed limit zone and avoid driving risks. This is an extremely unsafe practice.

[0004] Therefore, how to control the form specifications of vehicles traveling in speed limit areas and determine the compliance of vehicles are issues that need to be urgently addressed. Summary of the invention

[0005] To achieve the above objectives, this application provides the following technical solutions:

[0018] Determine whether the sub-interval average value of the driving speed of the vehicle to be tested for compliance analysis is less than the interval speed limit compliance value. If so, determine that the vehicle to be tested for compliance analysis is a compliance test vehicle.

[0022] Further, judging whether the vehicle to be analyzed for compliance is compliant based on the vehicle speed notification of each speed limit interval to be analyzed for compliance includes:

[0023] If the total number of vehicle speed notifications existing in each of the speed limit sections to be analyzed for compliance within the test period is less than the vehicle speed notification upper limit, the test vehicle to be analyzed for compliance is determined to be a compliance test vehicle.

[0024] Furthermore, the method further comprises:

[0043] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. According to the embodiments in the present application, all other embodiments collected by ordinary technicians in this field without creative work are within the scope of protection of this application.

Therefore, the features defined as "first", "second" and "third" can explicitly or implicitly include multiple features. In the description of this application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. All directional indications in the embodiments of this application (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or driving speed that includes a series of steps or modules is not limited to the listed steps or modules, but optionally also includes steps or modules that are not listed, or optionally also includes other steps or modules inherent to these processes, methods, products or driving speeds.

[0045] Reference to "embodiments" herein means that the specific features, structures, or characteristics described in conjunction with the embodiments may be included in multiple embodiments of the present application. The presence of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0046] like Figure 1 As shown, this embodiment proposes a vehicle compliance analysis method based on data visualization, which may include the following steps:

[0047] S101, collecting vehicle speed notifications for multiple speed limit intervals within a test period;

[0048] In this embodiment, the vehicle driving road may include several speed limit sections. Specifically, the present invention may collect vehicle speed notifications of each speed limit section in the vehicle driving road existing in the test cycle.

[0049] The vehicle speed notification may be any type of reminder notification or a reminder notification of a preset scenario, but the vehicle speed notification is only issued when the vehicle exceeds the speed limit within the speed limit interval.

[0050] In this embodiment, if the vehicle speed notifications of multiple speed limit intervals are concentrated in a short period of time on the vehicle driving road, the present invention can determine that the reminders of certain speed limit intervals may be caused by errors in the cloud platform system. Therefore, the present invention can periodically collect vehicle speed notifications existing in a certain time period on the vehicle driving road, and then can sequentially use the vehicle speed notifications collected each time in the time period to determine whether the reminders of certain speed limit intervals may be caused by errors in the cloud platform system.

[0051] Specifically, the test cycle can be the time period. The specific duration of the test cycle can be determined by technicians according to actual working conditions, and the present invention does not limit this.

[0052] Specifically, the present invention can set a corresponding vehicle tracking speed limit interval for each speed limit interval, use the vehicle tracking speed limit interval to track the speed limit interval, and collect vehicle positioning information generated by the vehicle tracking speed limit interval during the process of tracking the speed limit interval.

[0053] Afterwards, the present invention can collect the vehicle speed notifications of each speed limit interval existing in the test period from the vehicle positioning information of each speed limit interval in turn. For example, the present invention can collect the vehicle speed notification of the first speed limit interval existing in the test period from the vehicle positioning information of the first speed limit interval, and can collect the vehicle speed notification of the second speed limit interval existing in the test period from the vehicle positioning information of the second speed limit interval.

[0054] Specifically, the present invention can periodically collect vehicle speed notifications of each speed limit interval existing in the test period from the vehicle positioning information of each speed limit interval, and then use the vehicle speed notifications of each speed limit interval existing in the test period collected each time to determine whether the reminders of certain speed limit intervals are caused by the cloud platform system. For example, when the test period is 2 days, the present invention can collect vehicle speed notifications of each speed limit interval existing in the first 2 days and the second 2 days in sequence, use the vehicle speed notifications of each speed limit interval existing in the first 2 days to determine whether the reminders of certain speed limit intervals are caused by the cloud platform system, and use the vehicle speed notifications of each speed limit interval existing in the second 2 days to determine whether the reminders of certain speed limit intervals are caused by the cloud platform system.

[0055] Optionally, the vehicle speed notification may include a reminder notification of a preset scenario. In this case, step S101 may include:

[0056] Reminder notifications for preset scenarios are collected from vehicle positioning information in multiple speed limit zones within the test period.

[0057] Among them, the reminder notifications of preset scenarios may include reminder notifications of sudden changes in vehicle speed, long parking time and other types.

[0058] Specifically, the present invention can filter out reminder notifications of preset scenarios from the vehicle positioning information.

[0059] S102, performing visual analysis on the vehicle speed notifications of each speed limit interval to collect a visual analysis curve graph of each vehicle speed notification;

[0060] Specifically, the present invention can perform a visual analysis on the collected vehicle speed notifications for each speed limit interval, collect a visual analysis curve chart of the vehicle speed notifications for each speed limit interval, and then determine whether the reminders for certain speed limit intervals are caused by errors in the cloud platform system based on the visual analysis curve chart.

[0061] The present invention does not limit the visual analysis indicators to be collected for the above-mentioned visual analysis. For example, the visual analysis indicators to be collected for the compliance analysis may include the total number of vehicle speed notifications, the total number of speed limit intervals where reminder notifications exist, and the number of different types of vehicle speed notifications.

[0062] It is understandable that the present invention can determine the visual analysis method for vehicle speed notifications in each speed limit interval based on the visual analysis index items to be collected for compliance analysis.

[0063] S103, determining whether the visualization analysis curve chart meets the set compliance analysis activation scenario, if yes, completing step S104;

[0064] In this embodiment, when the visualization analysis curve graph meets the compliance analysis activation scenario, the present invention can determine that the reminders of certain speed limit intervals may be caused by errors in the cloud platform system; when the visualization analysis curve graph does not meet the compliance analysis activation scenario, the present invention can determine that the reminders of the vehicle's driving road may be caused by errors in the vehicle's driving road itself, rather than by errors in the cloud platform system.

[0065] The compliance analysis activation scenario may be formulated by technical personnel based on actual work conditions and work experience, etc., and the present invention does not limit this.

[0066] Optionally, the compliance analysis activation scenario may be: the total number of vehicle speed notifications is greater than or equal to the lower limit of the vehicle speed notification and the total number of speed limit intervals is greater than or equal to the lower limit of the number of speed limit intervals. In this case, the above step S102 may include:

[0067] Visualize and analyze the total number of vehicle speed notifications and the total number of speed limit warning intervals.

[0068] The total number of vehicle speed notifications may be the total number of vehicle speed notifications existing in each speed limit interval within the test period.

[0069] The total number of reminder speed limit intervals may be the total number of speed limit intervals of the reminder speed limit intervals (ie, speed limit intervals in which vehicle speed notifications exist).

[0070] Among them, the lower limit value of the vehicle speed notification and the lower limit value of the number of speed limit intervals can be formulated by technical personnel according to actual working conditions, and the present invention does not limit this.

[0071] Optionally, the compliance analysis activation scenario may also include the number of notifications of the total number of vehicle speed notifications within a unit time length (ie, the total number of vehicle speed notifications divided by the value of the test cycle).

[0072] Optionally, the compliance analysis activation scenario may also include the number of speed limit intervals existing in the total number of the reminder speed limit intervals per unit time (ie, the total number of reminder speed limit intervals divided by the value of the test period).

[0073] S104, according to the association relationship between the test vehicles and the speed limit intervals in the test vehicle set, multiple speed limit intervals associated with the test vehicle to be analyzed for compliance are all determined as speed limit intervals to be analyzed for compliance, and the test vehicle set includes multiple test vehicles;

[0074] Among them, each test vehicle in the test vehicle set can be an electronic driving speed, and the test vehicle can be configured with a speed limit range and support operation in the speed limit range.

[0075] The test vehicle to be analyzed for compliance may be a test vehicle in a set of test vehicles.

[0076] The cloud platform system may include a speed control module and test vehicles in a test vehicle set.

[0077] Among them, the speed control module is a module that can support working in the speed limit range and control the test vehicle.

[0078] In this embodiment, in order to improve the design efficiency of the speed limit interval and the interaction efficiency between the various components within the speed limit interval, the speed limit interval can be divided according to dimensions such as layers, subsystems and modules. After the division, the corresponding speed control architecture can be collected. At this time, the component module in the speed control architecture can be a speed control module.

[0079] Specifically, in the vehicle driving road and cloud platform system, there is a correlation between the speed limit zone, the speed control module and the test vehicle.

[0080] The vehicle driving road includes a first speed limit zone and a second speed limit zone. The speed control module in the cloud platform system includes a first vehicle computer, a second vehicle computer, a first private cloud server, a second private cloud server and a first log record table. The test vehicles in the cloud platform system include a first test vehicle, a second test vehicle, a third test vehicle and a fourth test vehicle.

[0081] Among them, the first vehicle computer, the first private cloud server and the first log recording table can be speed control modules for the first speed limit interval, the second vehicle computer, the second private cloud server and the first log recording table can be speed control modules for the second speed limit interval, the first vehicle computer and the second vehicle computer can be controlled on the first test vehicle, the first private cloud server can be controlled on the second test vehicle, the first log recording table can be controlled on the third test vehicle, and the second private cloud server can be controlled on the fourth test vehicle.

[0082] It is understandable that there is an association between the speed limit interval, the speed control module and the test vehicle. Specifically, the first speed limit interval can be associated with the first vehicle computer, the first private cloud server and the first log record table in sequence, and the second speed limit interval can be associated with the second vehicle computer, the second private cloud server and the first log record table in sequence; the first vehicle computer and the second vehicle computer can be associated with the first test vehicle, the first private cloud server can be associated with the second test vehicle, the first log record table can be associated with the third test vehicle, and the second private cloud server can be associated with the fourth test vehicle.

[0083] Among them, the speed control module of the first speed limit interval is sequentially controlled on the first test vehicle, the second test vehicle and the third test vehicle, and the speed control module of the second speed limit interval is sequentially controlled on the first test vehicle, the third test vehicle and the fourth test vehicle. Therefore, the present invention can be considered that the first speed limit interval is sequentially associated with the first test vehicle, the second test vehicle and the third test vehicle, and the second speed limit interval is sequentially associated with the first test vehicle, the third test vehicle and the fourth test vehicle.

[0084] Specifically, the present invention can utilize the association between the speed limit interval and the test vehicle to determine each speed limit interval associated with the test vehicle to be analyzed for compliance as a speed limit interval to be analyzed for compliance. Afterwards, the present invention can determine whether the test vehicle to be analyzed for compliance is compliant based on the vehicle speed notifications existing in each speed limit interval to be analyzed for compliance during the above test cycle, that is, determine whether the test vehicle to be analyzed for compliance is a compliance test vehicle, thereby determining whether the reminders existing in each speed limit interval to be analyzed for compliance are caused by an error of the test vehicle to be analyzed for compliance.

[0085] S105. Determine whether the vehicle to be tested for compliance analysis is compliant based on the vehicle speed notification for each speed limit zone to be analyzed for compliance.

[0086] Among them, the present invention can determine whether the vehicle to be tested for compliance analysis is a compliance test vehicle based on the vehicle speed notification existing in each speed limit section to be analyzed for compliance within the above test cycle.

[0087] Optionally, the present invention can determine whether the vehicle to be tested for compliance analysis is a compliance test vehicle based on the total number of vehicle speed notifications existing in each speed limit interval to be analyzed for compliance within the above test cycle.

[0088] Optionally, if the total number of vehicle speed notifications existing in each speed limit interval to be analyzed for compliance within the test cycle is less than the vehicle speed notification upper limit value, the test vehicle to be analyzed for compliance is determined to be a compliance test vehicle.

[0089] Among them, if the total number of vehicle speed notifications existing in each speed limit interval to be analyzed for compliance within the above-mentioned test cycle is less than the upper limit value of the vehicle speed notification, the present invention can determine that the vehicle to be analyzed for compliance is a compliant test vehicle; if the total number of vehicle speed notifications existing in each speed limit interval to be analyzed for compliance within the above-mentioned test cycle is not less than the upper limit value of the vehicle speed notification, the present invention can determine that the vehicle to be analyzed for compliance is a normal test vehicle.

[0090] The fourth set threshold value may be set by a technician according to actual working conditions, and the present invention does not limit this.

[0091] Optionally, the present invention can determine whether the vehicle to be tested for compliance analysis is a compliance test vehicle based on the number of reminder speed limit intervals in each speed limit interval to be analyzed for compliance.

[0092] Optionally, if during the above-mentioned test cycle, the proportion of reminder speed limit intervals in each speed limit interval to be analyzed for compliance is relatively large, the present invention can judge the vehicle to be analyzed for compliance as a compliance test vehicle; if during the above-mentioned test cycle, the proportion of reminder speed limit intervals in each speed limit interval to be analyzed for compliance is relatively small, the present invention can judge the vehicle to be analyzed for compliance as a normal test vehicle.

[0093] Optionally, during the above-mentioned test cycle, if the number of reminder speed limit intervals in the speed limit interval to be analyzed for compliance is greater than a certain value, the present invention may judge the vehicle to be analyzed for compliance as a compliance test vehicle; during the above-mentioned test cycle, if the number of reminder speed limit intervals in the speed limit interval to be analyzed for compliance is not greater than a certain value, the present invention may judge the vehicle to be analyzed for compliance as a normal test vehicle.

[0094] Specifically, when the present invention determines that the vehicle to be tested for compliance analysis is a compliance test vehicle, it can be considered that the reminders existing in each speed limit interval to be analyzed for compliance are caused by the compliance of the vehicle to be tested for compliance analysis. At this time, the actual error target can be the vehicle to be tested for compliance analysis, thereby effectively completing the determination of the actual error target.

[0095] Specifically, when the present invention determines that the test vehicle to be analyzed for compliance is a normal test vehicle, it can be considered that the reminders existing in each speed limit interval to be analyzed for compliance are caused by problems of the speed limit interval to be analyzed for compliance itself. At this time, the actual error target can be the speed limit interval to be analyzed for compliance, thereby effectively completing the determination of the actual error target.

[0096] Among them, after determining the actual error target, the present invention can remind the technician to check the error cause of the actual error target, thereby effectively improving the error handling efficiency.

[0097] Also in the present embodiment, after the visual analysis curve chart meets the above-mentioned compliance analysis activation scenario, the present invention can judge each test vehicle in the test vehicle set as the above-mentioned test vehicle to be subjected to compliance analysis in turn, so as to judge whether each test vehicle in the test vehicle set is compliant in turn, and realize compliance judgment of each test vehicle in the test vehicle set, thereby realizing judgment of the actual error target that causes the reminder in each speed limit interval.

[0098] Among them, if all test vehicles in the test vehicle set are normal test vehicles, the present invention can determine that the reminder existing on the road where the vehicle is traveling is caused by a problem in the speed limit section itself.

[0099] The vehicle compliance analysis method based on data visualization proposed in this embodiment can collect vehicle speed notifications of multiple speed limit intervals within a test period, and perform visual analysis on the vehicle speed notifications of each speed limit interval to collect a visual analysis curve chart of each vehicle speed notification, and determine whether the visual analysis curve chart complies with the set compliance analysis activation scenario. If so, based on the association between the test vehicles in the test vehicle set and the speed limit intervals, multiple speed limit intervals associated with the test vehicle to be analyzed for compliance are determined to be speed limit intervals to be analyzed for compliance. Based on the vehicle speed notifications of each speed limit interval to be analyzed for compliance, it is determined whether the test vehicle to be analyzed for compliance is compliant, thereby effectively achieving the determination of the actual error target.

[0100] in accordance with Figure 1 The steps shown are as follows: Figure 2 As shown, this embodiment proposes a second vehicle compliance analysis method based on data visualization. In this method, the above step S105 may specifically include steps S201, S202 and S203, wherein:

[0101] S201, determining the average sub-interval of the driving speed of the vehicle to be tested for compliance analysis based on the vehicle speed notification of each speed limit interval to be analyzed for compliance;

[0102] In this embodiment, in the process of judging whether the vehicle to be tested for compliance analysis is compliant based on the vehicle speed notification of the speed limit interval to be analyzed for compliance, if within the above-mentioned test cycle, the proportion of reminder speed limit intervals in each speed limit interval to be analyzed for compliance is relatively large, then the present invention can judge the vehicle to be tested for compliance analysis as a compliant test vehicle.

[0103] Among them, the average value of the driving speed sub-interval may be the proportion of the reminder speed limit interval in the speed limit interval to be analyzed for compliance.

[0104] Optionally, step S201 may specifically include:

[0105] Determine the number of first speed limit intervals, where the first speed limit interval number is the number of speed limit intervals to be analyzed for compliance in which there are vehicle speed notifications within the test period;

[0106] The ratio of the number of first speed limit intervals to the number of second speed limit intervals is judged as the average value of the driving speed sub-intervals of the vehicle to be tested for compliance analysis, and the number of second speed limit intervals is the total number of speed limit intervals of the speed limit intervals to be analyzed for compliance associated with the vehicle to be tested for compliance analysis.

[0107] The number of first speed limit intervals may be the number of speed limit intervals that are reminder speed limit intervals in each speed limit interval to be analyzed for compliance within the test cycle.

[0108] The second number of speed limit intervals may be the total number of speed limit intervals to be analyzed for compliance.

[0109] Specifically, the present invention can divide the number of the first speed limit intervals by the value collected by the number of the second speed limit intervals to determine the average value of the sub-intervals of the vehicle to be tested for compliance analysis. For example, if the number of speed limit intervals of the speed limit intervals to be analyzed for compliance associated with the vehicle to be analyzed for compliance is 5, and in the above test cycle, the number of reminder speed limit intervals in each speed limit interval to be analyzed for compliance is 3, then the average value of the sub-intervals of the vehicle to be analyzed for compliance can be 3 / 5, that is, 0.6.

[0110] S202, determining whether the average value of the sub-interval of the speed of the vehicle to be tested for compliance analysis is less than the compliance value of the speed limit in the interval, if yes, completing step S203;

[0111] The compliance bottom line value may be formulated by technical personnel according to actual working conditions, and the present invention does not limit this.

[0112] S203: Determine whether the vehicle to be tested for compliance analysis is a compliance test vehicle.

[0113] Specifically, the present invention can judge, in the test vehicle set, a test vehicle whose average value of a driving speed sub-interval is greater than or equal to a compliance bottom line value as a compliant test vehicle, and judge a test vehicle whose average value of a driving speed sub-interval is less than a compliance bottom line value as a normal test vehicle.

[0114] The vehicle compliance analysis method based on data visualization proposed in this embodiment, in the process of judging whether the vehicle to be tested for compliance analysis is compliant according to the vehicle speed notification in the speed limit interval to be analyzed for compliance, if within the above-mentioned test cycle, the proportion of reminder speed limit intervals in each speed limit interval to be analyzed for compliance is relatively large, then the vehicle to be tested for compliance analysis can be judged as a compliant test vehicle, thereby realizing the judgment of the actual error target that causes the reminder in the speed limit interval to be analyzed for compliance.

[0115] in accordance with Figure 1 The steps shown are as follows: Figure 3 As shown, this embodiment proposes a third vehicle compliance analysis method based on data visualization. The method may also include the following steps:

[0116] S301, collecting positioning information of the compliance test vehicle on the cloud platform system;

[0117] In this embodiment, similar to the vehicle tracking speed limit interval set on the speed limit interval, the test vehicle also has a corresponding tracking speed limit interval. When determining the compliant test vehicle in the test vehicle set, the present invention can collect the positioning information of the compliant test vehicle on the cloud platform system from the tracking speed limit interval of the compliant test vehicle.

[0118] S302. Output reminder notifications to the tracking driving speed of the compliance test vehicle and the tracking driving speed of the compliance speed limit interval in sequence. The compliance speed limit interval is the speed limit interval associated with the compliance test vehicle, and the positioning information is set in the reminder notification.

[0119] The tracked vehicle speed may be an electronic vehicle speed that is responsible for storing and processing positioning information.

[0120] Specifically, the tracked driving speed of the compliance test vehicle may be an electronic driving speed for storing and processing the positioning information of the compliance test vehicle.

[0121] It can be understood that the present invention can determine all speed limit intervals associated with the compliance test vehicle as compliant speed limit intervals.

[0122] Optionally, the present invention may also only determine the warning speed limit interval associated with the compliance test vehicle as the compliance speed limit interval.

[0123] The tracked driving speed in the compliant speed limit interval may be an electronic driving speed for storing and processing positioning information of the compliant speed limit interval.

[0124] It is understandable that the tracking speed of the compliance test vehicle can be the compliance test vehicle itself or other electronic driving speeds. The tracking speed of the compliance speed limit interval can also be the compliance test vehicle associated with it or other electronic driving speeds.

[0125] Specifically, the present invention can notify the technical personnel of the vehicle driving road and the cloud platform system by outputting reminder notifications to the compliant test vehicles and the tracked driving speeds in the compliant speed limit intervals, so that the technical personnel can grasp the actual error target that causes the reminder in the speed limit interval as soon as possible, and handle the error in time, thereby improving the error handling efficiency and business operation efficiency.

[0126] It is understandable that steps S301 and S302 may also be performed by the vehicle. Figure 2 In the method shown.

[0127] The vehicle compliance analysis method based on data visualization proposed in this embodiment can notify the technical personnel of the vehicle driving road and the cloud platform system by outputting reminder notifications to the compliance test vehicle and the tracked driving speed in the compliance speed limit interval, so that the technical personnel can grasp the actual error target that causes the reminder in the speed limit interval as soon as possible, and handle the error in time, thereby improving the error handling efficiency and business operation efficiency.

[0128] and Figure 1 The steps shown are related, such as Figure 4 As shown, a vehicle compliance analysis device based on data visualization is proposed in this embodiment. The device may include: a first acquisition module 101, a visualization analysis module 102, a first judgment module 103, a second judgment module 104 and a third judgment module 105, wherein:

[0129] The first collection module 101 is configured to complete: collecting vehicle speed notifications of multiple speed limit intervals within a test period;

[0130] In this embodiment, the vehicle driving road may include several speed limit sections. Specifically, the present invention may collect vehicle speed notifications of each speed limit section in the vehicle driving road existing in the test cycle.

[0131] The vehicle speed notification may be any type of reminder notification or a reminder notification for a preset scenario.

[0132] In this embodiment, if the vehicle speed notifications of multiple speed limit intervals are concentrated in a short period of time on the vehicle driving road, the present invention can determine that the reminders of certain speed limit intervals may be caused by errors in the cloud platform system. Therefore, the present invention can periodically collect vehicle speed notifications existing in a certain time period on the vehicle driving road, and then can sequentially use the vehicle speed notifications collected each time in the time period to determine whether the reminders of certain speed limit intervals may be caused by errors in the cloud platform system.

[0133] Specifically, the test cycle can be the time period. The specific duration of the test cycle can be determined by technicians according to actual working conditions, and the present invention does not limit this.

[0134] Specifically, the present invention can set a corresponding vehicle tracking speed limit interval for each speed limit interval, use the vehicle tracking speed limit interval to track the speed limit interval, and collect vehicle positioning information generated by the vehicle tracking speed limit interval during the process of tracking the speed limit interval.

[0135] Afterwards, the present invention can collect vehicle speed notifications of each speed limit interval existing in the test cycle from the vehicle positioning information of each speed limit interval in turn.

[0136] Specifically, the present invention can periodically collect vehicle speed notifications of each speed limit interval existing in a test period from the vehicle positioning information of each speed limit interval in turn, and then use the vehicle speed notifications of each speed limit interval existing in the test period collected each time to determine whether the reminders of the existence of certain speed limit intervals are caused by the cloud platform system.

[0137] Optionally, the vehicle speed notification may include a reminder notification of a preset scenario. At this time, the first acquisition module 101 is configured to complete: collecting reminder notifications of preset scenarios from vehicle location information of multiple speed limit intervals within the test period.

[0138] Among them, the reminder notifications of preset scenarios may include reminder notifications of sudden changes in vehicle speed, long parking time and other types.

[0139] Specifically, the present invention can filter out reminder notifications of preset scenarios from the vehicle positioning information.

[0140] The visual analysis module 102 is configured to perform: visual analysis of the vehicle speed notifications of each speed limit interval to collect a visual analysis curve graph of each vehicle speed notification;

[0141] Specifically, the present invention can perform a visual analysis on the collected vehicle speed notifications for each speed limit interval, collect a visual analysis curve chart of the vehicle speed notifications for each speed limit interval, and then determine whether the reminders for certain speed limit intervals are caused by errors in the cloud platform system based on the visual analysis curve chart.

[0142] The present invention does not limit the visual analysis indicators to be collected for the above-mentioned visual analysis. For example, the visual analysis indicators to be collected for the compliance analysis may include the total number of vehicle speed notifications, the total number of speed limit intervals where reminder notifications exist, and the number of different types of vehicle speed notifications.

[0143] It is understandable that the present invention can determine the visual analysis method for vehicle speed notifications in each speed limit interval based on the visual analysis index items to be collected for compliance analysis.

[0144] The first judgment module 103 is set to complete: judging whether the visual analysis curve chart meets the set compliance analysis activation scenario, and if so, activating the second judgment module 104;

[0145] In this embodiment, when the visualization analysis curve graph meets the compliance analysis activation scenario, the present invention can determine that the reminders of certain speed limit intervals may be caused by errors in the cloud platform system; when the visualization analysis curve graph does not meet the compliance analysis activation scenario, the present invention can determine that the reminders of the vehicle's driving road may be caused by errors in the vehicle's driving road itself, rather than by errors in the cloud platform system.

[0146] The compliance analysis activation scenario may be formulated by technical personnel based on actual work conditions and work experience, etc., and the present invention does not limit this.

[0147] Optionally, the compliance analysis activation scenario may be: the total number of vehicle speed notifications is greater than or equal to the lower limit of the vehicle speed notification and the total number of speed limit intervals is greater than or equal to the lower limit of the number of speed limit intervals. At this time, the above-mentioned visualization analysis module 102 is set to complete: visualization analysis of the total number of vehicle speed notifications and the total number of speed limit intervals.

[0148] The total number of vehicle speed notifications may be the total number of vehicle speed notifications existing in each speed limit interval within the test period.

[0149] The total number of reminder speed limit intervals may be the total number of speed limit intervals of the reminder speed limit intervals (ie, speed limit intervals in which vehicle speed notifications exist).

[0150] Among them, the lower limit value of the vehicle speed notification and the lower limit value of the number of speed limit intervals can be formulated by technical personnel according to actual working conditions, and the present invention does not limit this.

[0151] Optionally, the compliance analysis activation scenario may also include the number of notifications of the total number of vehicle speed notifications within a unit time length (ie, the total number of vehicle speed notifications divided by the value of the test cycle).

[0152] Optionally, the compliance analysis activation scenario may also include the number of speed limit intervals existing in the total number of the reminder speed limit intervals per unit time (ie, the total number of reminder speed limit intervals divided by the value of the test period).

[0153] The second judgment module 104 is configured to complete: according to the association relationship between the test vehicles in the test vehicle set and the speed limit intervals, all of the multiple speed limit intervals associated with the test vehicle to be analyzed for compliance are determined as the speed limit intervals to be analyzed for compliance, and the test vehicle set includes multiple test vehicles;

[0154] Among them, each test vehicle in the test vehicle set can be an electronic driving speed, and the test vehicle can be configured with a speed limit range and support the operation of the speed limit range, such as servers, mobile phones, desktop computers and tablets.

[0155] The test vehicle to be analyzed for compliance may be a test vehicle in a set of test vehicles.

[0156] The cloud platform system may include a speed control module and test vehicles in a test vehicle set.

[0157] The speed control module is a module that can support the speed limit interval to work and is controlled on the test vehicle. For example, the speed control module can be a log record table of the speed limit interval, a vehicle computer, and a private cloud server.

[0158] In this embodiment, in order to improve the design efficiency of the speed limit interval and the interaction efficiency between the various components within the speed limit interval, the speed limit interval can be divided according to dimensions such as layers, subsystems and modules. After the division, the corresponding speed control architecture can be collected. At this time, the component module in the speed control architecture can be a speed control module.

[0159] Specifically, in the vehicle driving road and cloud platform system, there is a correlation between the speed limit zone, the speed control module and the test vehicle.

[0160] Specifically, the present invention can utilize the association between the speed limit interval and the test vehicle to determine each speed limit interval associated with the test vehicle to be analyzed for compliance as a speed limit interval to be analyzed for compliance. Afterwards, the present invention can determine whether the test vehicle to be analyzed for compliance is compliant based on the vehicle speed notifications existing in each speed limit interval to be analyzed for compliance during the above test cycle, that is, determine whether the test vehicle to be analyzed for compliance is a compliance test vehicle, thereby determining whether the reminders existing in each speed limit interval to be analyzed for compliance are caused by an error of the test vehicle to be analyzed for compliance.

[0161] The third judgment module 105 is configured to complete: judging whether the vehicle to be subjected to compliance analysis is compliant according to the vehicle speed notification of each speed limit interval to be subjected to compliance analysis.

[0162] Among them, the present invention can determine whether the vehicle to be tested for compliance analysis is a compliance test vehicle based on the vehicle speed notification existing in each speed limit section to be analyzed for compliance within the above test cycle.

[0163] Optionally, the present invention can determine whether the vehicle to be tested for compliance analysis is a compliance test vehicle based on the total number of vehicle speed notifications existing in each speed limit interval to be analyzed for compliance within the above test cycle.

[0164] Optionally, if the total number of vehicle speed notifications existing in each speed limit interval to be analyzed for compliance within the test cycle is less than the vehicle speed notification upper limit value, the test vehicle to be analyzed for compliance is determined to be a compliance test vehicle.

[0165] Among them, if the total number of vehicle speed notifications existing in each speed limit interval to be analyzed for compliance within the above-mentioned test cycle is less than the upper limit value of the vehicle speed notification, the present invention can determine that the vehicle to be analyzed for compliance is a compliant test vehicle; if the total number of vehicle speed notifications existing in each speed limit interval to be analyzed for compliance within the above-mentioned test cycle is not less than the upper limit value of the vehicle speed notification, the present invention can determine that the vehicle to be analyzed for compliance is a normal test vehicle.

[0166] The fourth set threshold value may be set by a technician according to actual working conditions, and the present invention does not limit this.

[0167] Optionally, the present invention can determine whether the vehicle to be tested for compliance analysis is a compliance test vehicle based on the number of reminder speed limit intervals in each speed limit interval to be analyzed for compliance.

[0168] Optionally, if during the above-mentioned test cycle, the proportion of reminder speed limit intervals in each speed limit interval to be analyzed for compliance is relatively large, the present invention can judge the vehicle to be analyzed for compliance as a compliance test vehicle; if during the above-mentioned test cycle, the proportion of reminder speed limit intervals in each speed limit interval to be analyzed for compliance is relatively small, the present invention can judge the vehicle to be analyzed for compliance as a normal test vehicle.

[0169] Optionally, during the above-mentioned test cycle, if the number of reminder speed limit intervals in the speed limit interval to be analyzed for compliance is greater than a certain value, the present invention may judge the vehicle to be analyzed for compliance as a compliance test vehicle; during the above-mentioned test cycle, if the number of reminder speed limit intervals in the speed limit interval to be analyzed for compliance is not greater than a certain value, the present invention may judge the vehicle to be analyzed for compliance as a normal test vehicle.

[0170] Specifically, when the present invention determines that the vehicle to be tested for compliance analysis is a compliance test vehicle, it can be considered that the reminders existing in each speed limit interval to be analyzed for compliance are caused by the compliance of the vehicle to be tested for compliance analysis. At this time, the actual error target can be the vehicle to be tested for compliance analysis, thereby effectively completing the determination of the actual error target.

[0171] Specifically, when the present invention determines that the test vehicle to be analyzed for compliance is a normal test vehicle, it can be considered that the reminders existing in each speed limit interval to be analyzed for compliance are caused by problems of the speed limit interval to be analyzed for compliance itself. At this time, the actual error target can be the speed limit interval to be analyzed for compliance, thereby effectively completing the determination of the actual error target.

[0172] Among them, after determining the actual error target, the present invention can remind the technician to check the error cause of the actual error target, thereby effectively improving the error handling efficiency.

[0173] Also in the present embodiment, after the visual analysis curve chart meets the above-mentioned compliance analysis activation scenario, the present invention can judge each test vehicle in the test vehicle set as the above-mentioned test vehicle to be subjected to compliance analysis in turn, so as to judge whether each test vehicle in the test vehicle set is compliant in turn, and realize compliance judgment of each test vehicle in the test vehicle set, thereby realizing judgment of the actual error target that causes the reminder in each speed limit interval.

[0174] Among them, if all test vehicles in the test vehicle set are normal test vehicles, the present invention can determine that the reminder existing on the road where the vehicle is traveling is caused by a problem in the speed limit section itself.

[0175] The vehicle compliance analysis device based on data visualization proposed in this embodiment can collect vehicle speed notifications of multiple speed limit intervals within a test period, and perform visual analysis on the vehicle speed notifications of each speed limit interval to collect a visual analysis curve chart of each vehicle speed notification, and determine whether the visual analysis curve chart complies with the set compliance analysis activation scenario. If so, based on the association between the test vehicles in the test vehicle set and the speed limit intervals, multiple speed limit intervals associated with the test vehicle to be analyzed for compliance are determined to be speed limit intervals to be analyzed for compliance. Based on the vehicle speed notifications in each speed limit interval to be analyzed for compliance, it is determined whether the test vehicle to be analyzed for compliance is compliant, thereby effectively achieving the determination of the actual error target.

[0176] in accordance with Figure 4 As shown, Figure 5 As shown, this embodiment proposes a second vehicle compliance analysis device based on data visualization. In the device, the third judgment module 105 may include: a fourth judgment module 201, a fifth judgment module 202 and a sixth judgment module 203, wherein:

[0177] The fourth determination module 201 is configured to complete: determining the average sub-interval of the driving speed of the vehicle to be tested for compliance analysis according to the vehicle speed notification of each speed limit interval to be analyzed for compliance;

[0178] In this embodiment, in the process of judging whether the vehicle to be tested for compliance analysis is compliant based on the vehicle speed notification of the speed limit interval to be analyzed for compliance, if within the above-mentioned test cycle, the proportion of reminder speed limit intervals in each speed limit interval to be analyzed for compliance is relatively large, then the present invention can judge the vehicle to be tested for compliance analysis as a compliant test vehicle.

[0179] Among them, the average value of the driving speed sub-interval may be the proportion of the reminder speed limit interval in the speed limit interval to be analyzed for compliance.

[0180] Optionally, the fourth judgment module 201 may include: a seventh judgment module and an eighth judgment module, wherein:

[0181] A seventh judgment module is configured to complete: judging the number of first speed limit intervals, where the first speed limit interval number is the number of speed limit intervals to be analyzed for compliance in which there are vehicle speed notifications within a test period;

[0182] The eighth judgment module is configured to complete: judging the ratio of the number of first speed limit intervals to the number of second speed limit intervals as the average value of the driving speed sub-intervals of the vehicle to be tested for compliance analysis, and the number of second speed limit intervals is the total number of speed limit intervals of the speed limit intervals to be analyzed for compliance associated with the vehicle to be tested for compliance analysis.

[0183] The number of first speed limit intervals may be the number of speed limit intervals that are reminder speed limit intervals in each speed limit interval to be analyzed for compliance within the test cycle.

[0184] The second number of speed limit intervals may be the total number of speed limit intervals to be analyzed for compliance.

[0185] Specifically, the present invention may divide the number of first speed limit intervals by the number of second speed limit intervals to determine the value collected as the average value of the driving speed sub-interval of the vehicle to be tested for compliance analysis.

[0186] The fifth judgment module 202 is set to complete: judging whether the average value of the sub-interval of the vehicle to be tested for compliance analysis is less than the compliance value of the speed limit in the interval, and if so, activating the sixth judgment module 203;

[0187] The compliance bottom line value may be formulated by technical personnel according to actual working conditions, and the present invention does not limit this.

[0188] The sixth judgment module 203 is configured to complete: judging whether the vehicle to be subjected to compliance analysis test is a compliance test vehicle.

[0189] Specifically, the present invention can judge, in the test vehicle set, a test vehicle whose average value of a driving speed sub-interval is greater than or equal to a compliance bottom line value as a compliant test vehicle, and judge a test vehicle whose average value of a driving speed sub-interval is less than a compliance bottom line value as a normal test vehicle.

[0190] The vehicle compliance analysis device based on data visualization proposed in this embodiment, in the process of judging whether the vehicle to be tested for compliance analysis is compliant according to the vehicle speed notification of the speed limit interval to be analyzed for compliance, if within the above-mentioned test cycle, the proportion of reminder speed limit intervals in each speed limit interval to be analyzed for compliance is relatively large, then the vehicle to be tested for compliance analysis can be judged as a compliant test vehicle, thereby realizing the judgment of the actual error target that causes the reminder in the speed limit interval to be analyzed for compliance.

[0191] in accordance with Figure 4 As shown, this embodiment proposes a third vehicle compliance analysis device based on data visualization, which may also include: a second acquisition module and an output module, wherein:

[0192] The second acquisition module is configured to complete: collecting positioning information of the compliance test vehicle on the cloud platform system;

[0193] The output module is set to complete: outputting reminder notifications to the tracking driving speed of the compliance test vehicle and the tracking driving speed of the compliance speed limit zone in turn, the compliance speed limit zone is the speed limit zone associated with the compliance test vehicle, and the positioning information is set in the reminder notification.

[0194] In this embodiment, similar to the vehicle tracking speed limit interval set on the speed limit interval, the test vehicle also has a corresponding tracking speed limit interval. When determining the compliant test vehicle in the test vehicle set, the present invention can collect the positioning information of the compliant test vehicle on the cloud platform system from the tracking speed limit interval of the compliant test vehicle.

[0195] The tracked vehicle speed may be an electronic vehicle speed that is responsible for storing and processing positioning information.

[0196] Specifically, the tracked driving speed of the compliance test vehicle may be an electronic driving speed for storing and processing the positioning information of the compliance test vehicle.

[0197] It can be understood that the present invention can determine all speed limit intervals associated with the compliance test vehicle as compliant speed limit intervals.

[0198] Optionally, the present invention may also only determine the warning speed limit interval associated with the compliance test vehicle as the compliance speed limit interval.

[0199] The tracked driving speed in the compliant speed limit interval may be an electronic driving speed for storing and processing positioning information of the compliant speed limit interval.

[0200] It is understandable that the tracking speed of the compliance test vehicle can be the compliance test vehicle itself or other electronic driving speeds. The tracking speed of the compliance speed limit interval can also be the compliance test vehicle associated with it or other electronic driving speeds.

[0201] Specifically, the present invention can notify the technical personnel of the vehicle driving road and the cloud platform system by outputting reminder notifications to the compliant test vehicles and the tracked driving speeds in the compliant speed limit intervals, so that the technical personnel can grasp the actual error target that causes the reminder in the speed limit interval as soon as possible, and handle the error in time, thereby improving the error handling efficiency and business operation efficiency.

[0202] It can be understood that the second acquisition module and the output module can also be incorporated into the above-mentioned second vehicle compliance analysis device based on data visualization.

[0203] The vehicle compliance analysis device based on data visualization proposed in this embodiment can notify the technical personnel of the vehicle driving road and the cloud platform system by outputting reminder notifications to the compliance test vehicle and the tracking driving speed in the compliance speed limit interval, so that the technical personnel can grasp the actual error target that causes the reminder in the speed limit interval as soon as possible, and handle the error in time, thereby improving the error handling efficiency and business operation efficiency.
