Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides a method for acquiring a vehicle running track, which is used for solving the technical problem that enterprise vehicle management personnel cannot acquire vehicle running track information in real time.

The technical solutions proposed in the embodiments of the present application are described in detail below with reference to the accompanying drawings.

Fig. 1 is a flowchart of a method for obtaining a driving trajectory of a vehicle according to an embodiment of the present disclosure. As shown in fig. 1, the method mainly comprises the following steps:

step 101, obtaining a plurality of coordinate points of the vehicle in the current time period and a time point corresponding to each coordinate point.

In this application embodiment, each enterprise can be sent out the vehicle in the company of oneself, carries out tasks such as cargo transporter and personnel transport. The vehicles are all provided with GPS positioning equipment, the GPS positioning equipment can record the current running coordinate point of the vehicle, and the coordinate point is the longitude and latitude of the running position of the vehicle. And then uploading the recorded coordinate points to a plurality of track platforms for storage.

The number of vehicles in a large enterprise is large, and coordinate points are generated every moment when the vehicles run. If coordinate points of all vehicles inside the enterprise are stored in one track platform, the problem of large storage pressure or insufficient space is inevitable. Therefore, a number can be set for all vehicles, and the coordinate points of the vehicles can be stored in a plurality of track platforms in a slicing mode according to the numbered section. For example, a company has 100 vehicles numbered 1 to 100, coordinate points of the vehicles numbered 1 to 10 are stored in a first track platform and a second track platform, and coordinate points of the vehicles numbered 11 to 20 are stored in a third track platform and a fourth track platform. Therefore, the problem that coordinate points of hundreds of vehicles are stored on one track platform at the same time, and the calculation pressure is too high is solved.

It is conceivable that the GPS positioning device of the vehicle records the coordinate point of the vehicle at the same time as the time point at which the coordinate point was recorded. And the license plate number of the vehicle. And the coordinate points which are driven by the vehicle and the time points which correspond to the coordinate points are in one-to-one correspondence and are correlated, and then the coordinate points are stored in a plurality of track platforms. Therefore, in the track platform, each vehicle generates a file, all coordinate points of the vehicle and the time point of each coordinate point are recorded in the file, and the file is named by the license plate number. For example, the file name is: the number plate XX012345, the file records the coordinate point corresponding to the number plate, the recording format is: 117.08E, 36.67N, XX year XX month XX day XX minute XX second.

In the embodiment of the application, when vehicle management personnel in an enterprise perform overall vehicle arrangement and vehicle travel management, a positioning request acquiring instruction is sent to the track platform through computer equipment, and the positioning request acquiring instruction includes the license plate number of the vehicle which the management personnel want to view. Then the track platform searches in the track platform by taking the license plate number as search content, finds out coordinate points of the corresponding vehicle under the stored license plate number, records time points of the coordinate points, and returns the searched information to the computer equipment of the manager.

It should be noted that, when the administrator wants to check the driving condition of a certain vehicle at a certain time point, the administrator may further include a time period in the positioning request obtaining instruction sent by the computer device, then the track platform searches the license plate number and also uses the time period included in the instruction as search content, and returns all coordinate points of the vehicle in the time period to the computer device.

In the embodiment of the application, the GPS positioning equipment of the automobile is in a state of being started for a long time, so that the GPS positioning equipment is the most prone to failure of the automobile. If the GPS positioning device of the vehicle fails, the manager cannot acquire the coordinate information of the vehicle from the track platform corresponding to the vehicle, and cannot monitor the traveling state of the vehicle in real time. Thus, there is a need for monitoring vehicle GPS devices.

Specifically, a time period is preset, the number of coordinate points which should be recorded in the preset time period is determined, then the track platform is returned to the manager, and whether the number of coordinate points in the computer equipment is consistent with the number of coordinate points which should be recorded is determined. If not, the vehicle GPS device is proved to be in failure. For example, if the GPS device records the coordinate points of the vehicle travel every two seconds, the preset time period is 100 seconds, and 50 times of coordinate points should be recorded within the 100 seconds. If the number of the coordinate points returned by the track platform received by the computer equipment is only 40, the missing of part of the track coordinate points is proved, namely the coordinate points recorded by the GPS equipment are not accurate. The system can judge that the GPS equipment has a fault, and then sends the generated fault information of the GPS equipment to a manager.

And 102, integrating the plurality of coordinate points and the time point corresponding to each coordinate point to obtain a coordinate array.

In the embodiment of the application, after receiving the coordinate points returned by the track platform to the vehicle and the information such as the time points of the coordinate points, the computer device of the administrator integrates the coordinate points of the vehicle and the time points corresponding to the coordinate points to obtain a coordinate array of the vehicle. It is conceivable that the computer device completes the generation process of the coordinate array through an internal programming operation, and the generated coordinate array is the coordinate point of the vehicle carrying the time attribute mark.

It should be noted that the process of generating the coordinate array by programming the computer device is specifically completed by encoding character strings in JSON format, and the character strings include the coordinate array of the vehicle. Meanwhile, as the longitude and latitude coordinate values of the vehicle actually running are returned, and the electronic map is usually established in a two-dimensional coordinate system, the returned coordinate points also need to be converted into two-dimensional coordinate points, so as to determine the coordinate points on the electronic map.

And 103, drawing each coordinate point in the coordinate array one by one on a pre-acquired electronic map to obtain a running track of the vehicle in the current time period.

In the embodiment of the application, after the front end of the computer device receives the character strings coded by the rear end of the computer device through the JSON format, the coordinate array of the vehicle contained in the character strings of the JSON format is extracted. And traversing the coordinate array of the vehicle, so as to find out the coordinate point of the starting point of the vehicle and the coordinate point of the position where the vehicle runs at the current moment. All coordinate points of the vehicle contained in the coordinate array are marked on the electronic map one by one.

Further, after all the coordinate points are marked on the electronic map, two coordinate points adjacent to each other in time interval are connected by a line segment. And setting a mark of the vehicle at a position coordinate point on the electronic map where the vehicle runs at the current moment, wherein the mark is used for indicating the current running position of the vehicle on the electronic map. The vehicle logo may be in the shape of a car or may be in the shape of a triangle or a five-pointed star.

In the embodiment of the application, when the front-end page of the computer device is used for drawing the vehicle track, the current driving direction of the vehicle needs to be determined. Firstly, traversing operation is carried out on the coordinate array, so that a coordinate point before the coordinate point at the current driving moment of the automobile is found. An angle calculation is then made between these two coordinate points. For example, if the corresponding coordinate point of the vehicle driving to the current position on the electronic map is (2, 2) and the coordinate point recorded immediately before the coordinate point is (1, 1), the current driving direction of the vehicle is 45 degrees north east after the vector angle calculation. And according to the calculated driving direction of the vehicle, adjusting the orientation of the vehicle mark in the electronic map so that the current orientation of the vehicle mark in the electronic map can represent the specific orientation of the vehicle in the actual driving process.

In the embodiment of the application, after the whole track is drawn, the computer device can automatically calculate the occupation ratio of the whole track route map on the whole electronic map. If the whole track route occupies a smaller proportion on the electronic map space, only a short track route is occupied, and the track route is positioned at the corner position of the electronic map. The front page is scaled in the system to make the driving track adapt to the current page and display, and the driving track of the vehicle is always placed in the middle of the electronic map page. In addition, the manager can also enlarge or reduce the driving track or specifically view the details of a certain driving track by manually adjusting or dragging the track route map. Fig. 2 is a display diagram of a vehicle driving track page provided by the embodiment of the application, in which a starting point, an ending point, and a whole track line of the vehicle driving track are visible on a front end page, and a license plate number, a starting time, an ending time, a driving mileage, and a driving duration of the vehicle are recorded above the page, so that a manager can intuitively know the driving track of each vehicle.

And 104, performing delay processing on the drawing operation based on a preset delay algorithm so as to dynamically display the driving track on the electronic map.

In the embodiment of the application, the computer device of the administrator dynamically presents the line segment connecting two coordinate points on the electronic map and the advancing process of the vehicle mark on the map in the form of animation by calling a SetInterval delay algorithm in JavaScript. The SetInterval algorithm functions to call functions, methods or objects at regular intervals when an animation is played. The algorithm can be updated in real time as the coordinates returned from the track platform are continually received, using both the addition of the track line segment and the advance of the vehicle marker. In the SetInterval algorithm, the time of the change of the animation picture can be set, for example, one change in 2 seconds is set, and then it appears on the electronic map that the vehicle mark advances every 2 seconds.

In the embodiment of the application, the computer device may further calculate an actual distance length traveled by the vehicle in a certain time period. The specific calculation process is as follows: and calculating the length of the line between all the time intervals and two adjacent coordinate points on the electronic map. All the segment lengths are then added to obtain a total segment length. And then calculating according to the current scale of the electronic map. The total length of the line segments represents the distance length in practice. Since the recording time point of each coordinate point is known, the duration of this period of time is also known. And comparing the time length of the period of time, the preset distance threshold value and the calculated distance length to obtain whether the vehicle is overspeed or not. And overspeed information of the vehicle can be generated and sent to a manager if the vehicle is overspeed, so that the manager can make corresponding decisions in time. Or the calculated distance length is divided by the time, the vehicle speed of the vehicle can be calculated. And then compared with the preset vehicle speed, whether the vehicle runs at an overspeed or not can be judged.

According to the method for acquiring the vehicle running track, the vehicle-mounted GPS equipment is in butt joint with the track platforms to store the real-time coordinate points of the vehicle, an enterprise vehicle manager only needs to input the license plate number into the system, the system can automatically search the coordinate points of the vehicle in the track platforms and return the coordinate points to the computer equipment of the manager, the coordinate points are drawn on an electronic map by the front end in the form of the dynamic running track, the manager can visually see the running condition of the vehicle and timely judge whether the vehicle runs at an overspeed or not, the vehicle-mounted GPS positioning equipment has the problems of failure and the like, so that corresponding countermeasures are timely made, and the management efficiency of an enterprise on the vehicle is improved.
