Problems solved by technology

However, it does not involve monitoring vehicle driving status information such as whether the vehicle is on the planned driving route
In addition, in the method described in the Chinese Patent Document 1, there is no means for intuitively grasping the driving status information of these vehicles.
[0010] In addition, although the method described in the Chinese Patent Document 2 analyzes and visualizes vehicle GPS data and abnormality monitoring, the method described in the Patent Document 2 is not an intuitive visualization method, and this method cannot be used in the field of real-time monitoring

[0038] figure 2 is a flowchart showing a vehicle running condition monitoring method according to the first embodiment of the present invention.

[0039] Such as figure 2 As shown, in step S201, the GPS data receiving module 10 receives GPS data information.

[0040] Here, according to the sampling frequency (Sampling_Rate-SR), the real-time GPS data sent by the vehicle includes four basic fields: real-time speed (S), longitude (Lon), latitude (Lat), and sampling time (T) (ie, time stamp).

[0041]In step S203, the real-time speed of the vehicle is determined according to the received GPS data information. In this example, the real-time speed of the vehicle can be directly read from the received GPS data information.

[0042] It should be pointed out that the present invention is not limited thereto, and the average speed of the vehicle within the sampling interval can also be calculated according to the comparison between the previous latitude and longitude information ...

[0097] Figure 12 is a flowchart showing a vehicle running condition monitoring method according to a second embodiment of the present invention.

[0098] Such as Figure 12 As shown, in step S1201, the GPS data receiving module 10 receives GPS data information.

[0099] In step S1213, the latitude and longitude information of the vehicle's current location is determined according to the received GPS data information.

[0100] In step S1215, the vehicle driving condition calculation module 21 determines whether the vehicle is on the predetermined driving route according to the latitude and longitude information of the vehicle's current location determined in step S1213.

[0101] Then, in step S1217, the visualization graphic attribute calculation module 22 determines the visualization shape according to the result of whether the vehicle is on the planned predetermined route determined in step S1215.

[0102] In step S1219, the visualization data such as the visualization sh...

Abstract

According to the present invention, a method and device for monitoring the driving condition of a vehicle are provided. The method includes the steps of receiving GPS data information sent from the vehicle; determining the current position of the vehicle according to the GPS data information sent from the vehicle; and determining whether the vehicle is on a predetermined travel path according to the current position of the vehicle.

Description

technical field [0001] The invention relates to a vehicle running condition monitoring method and device, which can quickly and reliably monitor the vehicle running condition in real time, and can perform intuitive visualization processing on the vehicle running condition. Background technique [0002] In modern society, logistics transportation has become a very developed industry. Items are transported by logistics on roads and in huge quantities. Therefore, in the field of logistics, it is necessary to grasp the relevant information of vehicles and items in a timely and accurate manner, so as to facilitate the scheduling of vehicles and the status of items. This facilitates the control of the vehicle during logistics transportation to reduce transportation costs. [0003] Therefore, how to monitor the driving condition of the vehicle during the logistics transportation process has become a problem that has received widespread attention. In the field of logistics, usual...
