The method embodiments described below are described by way of example with the execution subject being a computer device.
Fig. 2 is a flowchart illustrating a method for triggering entry and exit of a vehicle into and out of a fence according to an embodiment. The embodiment relates to a specific process of determining that a vehicle enters a preset fence according to the current position and the destination position of the vehicle by a computer device. As shown in fig. 2, the method may include the steps of:
s201, acquiring a current first position and a current destination position of a vehicle when the vehicle drives to a preset fence.
The destination position refers to a position to which the vehicle finally arrives, and the preset fence refers to an electronic fence which is generated by the computer device in advance according to the destination position and comprises the destination position. Optionally, the preset fence may be a circular fence or a polygonal fence. The circular fence refers to a circular electronic fence which is generated by computer equipment according to a destination position, takes the destination position as a circle center, and takes a preset length as a radius, wherein the preset length can be determined according to an actual situation, and can be 1 kilometer, 2 kilometers and the like. The polygonal fence refers to a polygonal electronic fence which is generated by a computer device according to a destination position and a preset map component and comprises the destination position. Optionally, the number of the sides of the polygonal fence may be determined according to actual situations, and may be a quadrangular fence, a pentagonal electronic fence, or the like, which is not limited in this embodiment. Alternatively, the preset map component may be a height map, a Baidu map, or the like.
Specifically, when the vehicle is driven to the preset fence, the vehicle and the destination may be scanned by using a Geographic Information System (GIS) to obtain longitude and latitude Information of the current position of the vehicle and longitude and latitude Information of the destination position, and the longitude and latitude Information of the destination position of the vehicle is transmitted to the computer device.
S202, calculating a first straight-line distance between a current first position and a destination position of the vehicle.
The vehicle is driven from the current first position to the destination position, the driving path may be a straight line or a curve, and the straight line between the two points is the shortest. Thus, the computer device calculates a first linear distance between the current first position of the vehicle and the destination position, and the resulting distance is then the shortest.
Specifically, after obtaining the current first location and the destination location of the vehicle, the computer device may calculate a first linear distance between the current first location and the destination location of the vehicle using the map component.
S203, obtaining a first time length of the current first position of the vehicle reaching the destination position according to the first straight-line distance.
Optionally, the computer device may obtain a first time period for the current first position of the vehicle to reach the destination position according to a ratio of the first linear distance to a preset speed, where the preset speed is in a range from 50 km/h to 120 km/h.
And S204, when the first straight-line distance is not greater than a preset first distance, determining that the vehicle enters the preset fence, and recording the starting time of the first time length as the time when the vehicle enters the preset fence, wherein the preset first distance is the shortest distance between a destination position and the preset fence, and the destination position is at the center position of the preset fence.
The destination position is located at the center position of the preset fence, and when the preset fence is a circular fence, the preset first distance is the radius of the circular fence; when the preset fence is a polygonal fence, the preset first distance is the shortest distance between the destination position and each edge of the polygonal fence, so that when a vehicle enters the fence from any direction of the preset fence, the judgment can be carried out by using the preset first distance. In addition, the first duration has a start time and an end time, the start time is a current time when the computer device calculates the first duration, and the end time refers to a current time when the computer device waits for the first duration.
Specifically, after obtaining the first linear distance, the computer device may compare the first linear distance with a preset first distance, and when the first linear distance is not greater than the preset first distance, that is, when the first linear distance is less than or equal to the preset first distance, the computer device may determine that the vehicle enters the preset fence. At this time, the computer device does not need to record the first time length, and can directly record the starting time of the first time length as the time when the vehicle enters the preset fence.
The method for triggering the vehicle to enter and exit the fence includes the steps of obtaining a current first position and a destination position of the vehicle when the vehicle drives to a preset fence, calculating a first linear distance between the current first position of the vehicle and the destination position, calculating a first duration between the current first position of the vehicle and the destination position according to the first linear distance, and comparing the first linear distance with a preset first distance, wherein the preset first distance is a shortest distance between the destination position and the preset fence, the destination position is located at a center position of the preset fence, and when the first linear distance is not greater than the preset first distance, determining that the vehicle enters the preset fence, and recording a start time of the first duration as a time when the vehicle enters the preset fence. In this embodiment, since the first linear distance between the current position and the destination position of the vehicle is compared with the preset first distance, when the first linear distance is not greater than the preset first distance, it is determined that the vehicle enters the preset fence, and the start time of the first duration obtained through calculation is recorded as the time when the vehicle enters the preset fence, so that the method can record the time when the vehicle enters the fence, and the phenomenon that the recording is not triggered when the vehicle enters the fence can be avoided to a certain extent.
Fig. 3 is a flowchart illustrating a method for triggering entry and exit of a vehicle into and out of a fence according to another embodiment. The embodiment relates to a specific process that when the computer device determines that the first linear distance is greater than the preset first distance, the computer device needs to delay for a period of time and then execute the step of S201. On the basis of the above embodiment, as shown in fig. 3, the method may further include the steps of:
s205, when the first straight-line distance is larger than a preset first distance, delaying the first time, and then returning to the step of acquiring the current first position and the destination position of the vehicle when the vehicle drives to a preset fence.
Specifically, when the computer device compares the first linear distance with a preset first distance, and when the first linear distance is greater than the preset first distance, the computer device determines that the vehicle does not enter the preset fence, delays the first duration obtained by the calculation, and then returns to the step of executing the step S201.
When the step S201 is executed, the computer device obtains a new current first position of the vehicle again, calculates a new first linear distance, obtains a new first time length, compares the new first linear distance with the preset first distance, determines that the vehicle enters the preset fence when the new first linear distance is not greater than the preset first distance, and records a start time of the new first time length as a time when the vehicle enters the preset fence.
Wherein, the new first duration and the first duration may not be the same in size.
In the triggering method for the vehicle to enter and exit the fence provided by the embodiment, when the first straight-line distance is greater than the preset first distance, the first duration is delayed, and the step of acquiring the current first position and the current destination position of the vehicle when the vehicle drives to the preset fence is continuously executed. In this embodiment, since the current position of the vehicle at each time does not need to be collected to calculate the first linear distance, and the first linear distance is sent to the computer device to be compared with the preset first distance for judgment, the judgment times are small, and the calculation amount is small, the method does not need the computer device to have high performance, that is, the method can reduce the performance requirement of the computer device to a certain extent.
Fig. 4 is a flowchart illustrating a method for triggering entry and exit of a vehicle into and out of a fence according to another embodiment. The embodiment relates to a specific process of determining that a vehicle leaves a preset fence after the computer device determines that the vehicle enters the preset fence. On the basis of the above embodiment, as shown in fig. 4, the method may further include the steps of:
s401, acquiring a current second position of the vehicle when the vehicle is driven out of a preset fence.
Specifically, after the vehicle is operated at the destination position in the preset fence, the vehicle can exit the preset fence, when the vehicle exits, the geographic information system can be used for scanning the vehicle and the destination to obtain longitude and latitude information of the current position of the vehicle and longitude and latitude information of the destination position, the longitude and latitude information of the current position of the vehicle and the longitude and latitude information of the destination position are transmitted to the computer device, the computer device can obtain the current position and the destination position of the vehicle by calculating the longitude and latitude information of the current position of the vehicle and the longitude and latitude information of the destination position, and the current position of the vehicle is recorded as a current second position of the vehicle.
S402, calculating a second straight-line distance between the current second position of the vehicle and the destination position.
Specifically, after obtaining the current second position and the destination position of the vehicle, the computer device may calculate a second straight-line distance between the current second position and the destination position of the vehicle by using the map component.
And S403, when the second straight-line distance is greater than a preset second distance, determining that the vehicle leaves the preset fence, wherein the preset second distance is the longest distance between the destination position and the preset fence.
The preset second distance is the longest distance between the destination position and the preset fence, so that the vehicle can be judged by utilizing the preset second distance when leaving the preset fence from any direction of the preset fence.
Specifically, after obtaining the second linear distance, the computer device may compare the second linear distance with a preset second distance, and when the second linear distance is greater than the preset second distance, the computer device may determine that the vehicle leaves the preset fence.
The method for triggering the vehicle to enter and exit the fence includes first obtaining a current second position of the vehicle when the vehicle exits the preset fence, then calculating a second linear distance between the current second position of the vehicle and a destination position, and finally comparing the second linear distance with the preset second distance, and when the second linear distance is greater than the preset second distance, determining that the vehicle leaves the preset fence. In this embodiment, since the second straight-line distance between the current position and the destination position of the vehicle is compared with the preset second distance, and when the second straight-line distance is greater than the preset first distance, it is determined that the vehicle leaves the preset fence, the method can know whether the vehicle leaves the preset fence.

s404, when the second straight-line distance is not greater than the preset second distance, delaying the preset second time, and returning to the step of acquiring the current second position of the vehicle when the vehicle is driven out of the preset fence; and when the vehicle is determined to leave the preset fence, recording the end time of the second time length as the time when the vehicle leaves the preset fence.
Optionally, the preset second time period ranges from 5 seconds to 15 seconds.
Specifically, when the computer device compares the second linear distance with the preset second distance, and when the second linear distance is not greater than the preset second distance, that is, the second linear distance is less than or equal to the preset second distance, the computer device may determine that the vehicle does not leave the preset fence, the computer device may delay the preset second time period, and then return to the step of performing S401. When it is determined that the vehicle leaves the preset fence in the step S403, the end time of the second time period may be recorded as the time when the vehicle leaves the preset fence.
