[0003] However, the route is often not a straight avenue. Simply measuring the current position coordinates of the vehicle and calculating the straight-line distance from the end point cannot truly reflect the distance between each vehicle. It is not suitable for accurate monitoring and management of the task process. It is very important to calculate the accurate distance of the route

Embodiment Construction
[0046] The present invention will be further described in detail through the following examples in conjunction with the accompanying drawings. The following examples are explanations of the present invention and the present invention is not limited to the following examples.
[0047] Such as figure 1 As shown, the method for measuring and calculating the dynamic vehicle distance of curved path based on Beidou positioning of the present invention comprises the following steps:
[0048] Step 1: Set the vehicle travel route; plan the actual task starting point, end point and task travel route, obtain the initial coordinate point data based on the starting point, and set the task travel distance to zero.
[0049] Step 2: Obtain the current position coordinate information of the vehicle in real time; obtain the vehicle point through the Beidou positioning module device.
[0050] Step 3: Save the track information of each vehicle;
[0051] Use the vehicle number as the KEY for dat...

The invention discloses a method for calculating dynamic distances of a curved path based on Beidou positioning. The method comprises the following steps of: setting a travel route of each vehicle; obtaining current position coordinate information of the vehicle in real time; saving track information of each vehicle; correspondingly determining a nearest coordinate point on the travel route according to the vehicle coordinates; determining a vehicle relationship; calculating a vehicle track distance. According to the method for calculating dynamic distances of the curved path based on the Beidou positioning, the distance measurement deviation of two points is solved, distances of the vehicles are further accurately, and the management of the driving and order management and arrangement atthe scene are facilitated.
Description
technical field [0001] The invention relates to a method for measuring and calculating vehicle distance, in particular to a method for measuring and calculating dynamic vehicle distance on a curved path based on Beidou positioning. Background technique [0002] In all kinds of large-scale activities, you can often see convoys. In some important activities, there are strict requirements for the maintenance of the distance between vehicles in the driving process, as well as the time interval and sequence of arriving at the scene. In order to standardize and order the management, the monitoring center needs to know the dynamic real-time position, sequence and interval distance of each vehicle at any time, and the importance of the distance measurement between the front and rear vehicles is revealed. [0003] However, the route is often not a straight avenue. Simply measuring the current position coordinates of the vehicle and calculating the straight-line distance from the end...
