specific Embodiment approach 1

[0019] The driving record chart analysis and presentation method of the embedded vehicle driving recorder of the present embodiment, combined with figure 1 As shown, the method is realized through the following steps:

[0020] For the collected driving status information of each vehicle and the driving behavior information of each driver,

[0021] Step 1, using the collected vehicle driving state information as discrete original vehicle driving state byte data points, and storing the collected driver's driving behavior information as discrete original driving behavior byte data points;

[0022] Step 2. Read the discrete raw data points of step 1 one by one through the polling algorithm;

[0023] Step 3. For the discrete original data points read in step 2, judge whether they are valid data by comparing with the reference value of the design library:

[0024] If it is not valid data, return to step 2 to continue reading;

[0025] If it is valid data, proceed to step 4;

specific Embodiment approach 2

[0028] The difference from the first embodiment is that, in the method for analyzing and presenting the driving record chart of the embedded vehicle driving recorder in this embodiment, the process of comparing with the reference value of the design library described in step 3 to determine whether it is valid data is as follows: The reference value of the design library refers to the safe driving speed intervals of different ranges set according to different vehicles, then, determine whether the discrete original data points read are in the safe driving speed interval set by the reference value of the design library,

[0029] If it is within the safe driving speed range set by the reference value of the design library, the read discrete raw data points are valid data;

[0030] If it is not within the safe driving speed range set by the reference value of the design library, the read discrete raw data points are not valid data.

specific Embodiment approach 3

[0031] The difference from the specific embodiment 1 or 2 is that, in the method for analyzing and presenting the driving record chart of the embedded vehicle driving recorder in this embodiment, as described in step 4, the effective data in step 3 are fitted and calculated by the discrete data fitting method The process is to use one or two methods of linear fitting and polynomial fitting models to fit the discrete original vehicle driving state byte data points and the discrete original driving behavior byte data points into smooth data curves respectively , to truly present the driving state of the vehicle and the driving behavior of the driver, specifically:

[0032] Let the discrete original vehicle driving state byte data points and the discrete original driving behavior byte data points use discrete sampling points S(x i ,y i ) means that x i Represents discrete vehicle speed sampling points, y i Represents the vehicle speed value corresponding to the sampling point,...

Abstract

The invention discloses a method for analyzing and presenting a travel record chart of an embedded vehicle traveling data recorder and belongs to the field of data analysis. Currently, display of an embedded display screen is achieved in a discrete point broken line mode, which can not reflect real vehicle traveling data and driving behaviors of a driver described by discrete data. The method comprises the steps of conducting storage with acquired vehicle traveling state information serving as discrete original vehicle traveling state byte data points and acquired driver driving behavior information as discrete original driving behavior byte data points; reading the discrete original data points one by one by means of the roll polling algorithm; for the read discrete original data points, conducting fitting calculation on effective data with the discrete data fitting method; displaying a continuous curve obtained through fitting calculation on an embedded display. By the adoption of the method, discrete vehicle traveling state byte data can be fitted into a smooth data curve easily and quickly.

Description

technical field [0001] The invention relates to a method for analyzing and presenting a driving record chart of an embedded vehicle driving recorder. Background technique [0002] The original byte data recorded by the vehicle is discrete data. The discrete data forms a chart curve that is not continuous and cannot be directly presented in the form of a chart. This discrete original byte data is not suitable for law enforcement such as traffic police and other law enforcement officers. It can be used when used; the current embedded display shows the discrete point polyline presentation method, which cannot truly reflect the real vehicle driving records and driver driving behavior described by the discrete data. [0003] In addition, the current application technology requires multiple complex operations by humans. The driving record data of the embedded vehicle driving recorder is stored in the terminal device as discrete byte data, which requires wireless, wired, storage me...
