Embodiment Construction

[0051] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0052] Step 1. Cleaning and restoration of truck monitoring data

[0053] 1) Trajectory data segmentation. The historical monitoring data of trucks are stored by time, monitoring data d τ ={p τ ,v τ ,q τ ,t τ},τ=1,2,…,n, where p τ is the location information, p τ ={x τ ,y τ ,z τ},x τ ,y τ ,z τ are the longitude, latitude and elevation information of the vehicle respectively; v τ is the vehicle speed, the unit is km / h, q τ is the vehicle torque value in N.m; t τ It is the timestamp of the monitoring data. Check the vehicle history data sequentially according to the timestamp of the detection data, if t τ -t τ-1 >4 hours, then {d 1 , d 2 ,...,d τ-1 , d τ} constitute a new trajectory segment, and then make further judgments: if t τ-1 -t 1 τ Start sequential processing.

[0054] 2) Cleaning and repairing of vehicle speed data. Retriev...

Abstract

The invention discloses a loading and unloading place identification method based on truck monitoring data. The loading and unloading place identification method comprises the steps of cleaning and restoration of the truck monitoring data, parking point judgment, trajectory diluting, determination of turn-back angle threshold values and judgement of vehicle load change, and finally real loading and unloading parking points are identified. Cargo station positions can be mined from massive data, automatic data acquisition can be achieved, and station databases can be effectively established. Cargo allocation information is pushed for drivers by analyzing driver behaviors, and intelligent cargo allocation is achieved.

Description

technical field [0001] The invention belongs to the technical field of data mining, and in particular relates to a method for identifying loading and unloading locations based on truck monitoring data. Background technique [0002] The country requires road vehicles to be equipped with a vehicle monitoring system, which will generate a large amount of data when the vehicle is running. Mining vehicle monitoring data and analyzing driver preference characteristics can provide them with more personalized geographic information services. All parking spots can be found out by judging the speed, presence or absence of GPS points, and the envelope radius, but many parking spots are often traffic lights, where drivers rest and eat along the way. And because more and more goods are transported in the form of drop-and-pull transportation, the loading and unloading time is very short, and the loading and unloading location of the vehicle cannot be judged only by the length of the truck...
