Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1 is a flowchart of a method for generating GPS route simulation data according to an embodiment of the present invention. As shown in fig. 1, the method includes:
step 101, obtaining a navigation route from a preset starting point to a preset ending point through third party map software;
firstly, setting a starting point and an ending point, namely the preset starting point and the preset ending point; and obtaining a navigation route from a preset starting point to a preset ending point through third-party map software. The third party map software may be, for example, a Goldmap, a hundred degree map, etc.
102, acquiring coordinate data of an existing GPS point in the navigation route by using an API (application program interface) of the third-party map software;
the third party map software provides coordinate data externally through the published API. Thus, the coordinate data of the existing GPS points in the navigation route can be acquired using the API interface of the third party map software. The coordinate data of the existing GPS points are the coordinate data of the GPS points in the navigation route provided by the third-party map software.
Step 103, generating coordinate data of an additional GPS point between two adjacent existing GPS points in the navigation route according to a preset vehicle speed, a preset transmission frequency of the coordinate data of the GPS points and the coordinate data of the two adjacent existing GPS points;
the GPS points in third party map software such as the Goldmap are not continuous points, that is, GPS coordinates are only found in curves, or in routes with radians, where there are coordinates at both ends. Because the track of the GPS route is formed by continuous points, the GPS route simulation data can not be formed only according to the existing GPS points in the third party map software, and the coordinate data of the additional GPS points and the coordinate data of the existing GPS points are needed to be generated to form the GPS route simulation data together.
Specifically, according to a preset vehicle speed, a preset transmission frequency of the coordinate data of the GPS points and the coordinate data of two adjacent existing GPS points, generating coordinate data of an additional GPS point between the two adjacent existing GPS points in the navigation route. The preset transmission frequency refers to a transmission frequency when the GPS point coordinate data is sent to the vehicle-mounted terminal equipment to be tested in the test process, and can be preset. For example, if the preset transmission frequency is 1s, the coordinate data of one GPS point is transmitted to the vehicle-mounted terminal device to be tested every second. The distance travelled by the vehicle at each data transmission interval can be obtained from a preset vehicle speed (representing the running speed of the vehicle, which can be preset) and the preset transmission frequency. For example, when the preset transmission frequency is 1s, the distance travelled by the vehicle per second can be obtained according to the preset vehicle speed.
Therefore, it is possible to know how long it takes to transmit one GPS point and how long it is to transmit one GPS point through, based on the preset vehicle speed and the preset transmission frequency. After the information is obtained, the position information of the two adjacent existing GPS points can be obtained according to the coordinate data of the two adjacent existing GPS points, and the route for arranging the additional GPS points between the two adjacent existing GPS points can be further obtained according to a preset rule. And sequentially arranging additional GPS points on the obtained route according to the acquired interval distance of the GPS points, thereby obtaining the coordinate data of the additional GPS points between two adjacent existing GPS points.
The route in which the additional GPS points are arranged between the two adjacent existing GPS points is obtained according to a preset rule, wherein the preset rule may be, for example, straight line connection between the two adjacent existing GPS points or curve connection according to a set manner. Of course, other implementations are also possible. The navigation route between the preset starting point and the preset ending point is mainly used for acquiring the existing GPS data, is not used for limiting the track information of the GPS data when the test is carried out, and the track of the finally formed GPS data can be consistent with the navigation route or can be partially deviated.
And 104, composing the GPS route simulation data from the preset starting point to the preset ending point by the coordinate data of the existing GPS points and the coordinate data of the additional GPS points.
After the coordinate data of the additional GPS points are obtained, the coordinate data of the additional GPS points are combined with the coordinate data of the existing GPS points, so that the GPS points which are distributed continuously are obtained and can be used for testing, and therefore GPS route simulation data for testing can be obtained. The starting point of the GPS route simulation data is the preset starting point, the ending point is the preset ending point, and the track is the track formed by the GPS route simulation data together.
According to the embodiment of the invention, the GPS route simulation data for testing can be obtained without actual vehicle testing, so that the requirement of development testing is met, the track generation speed is high and convenient, the traffic and labor cost can be reduced, and the use is convenient; in addition, according to the test requirement, the embodiment of the invention can change the route rapidly by modifying the preset starting point and the preset ending point.
According to the embodiment of the invention, the existing GPS data is obtained by utilizing the third-party map software, the additional GPS data is further generated, and the existing GPS data and the additional GPS data jointly form the GPS route simulation data for testing, so that the efficiency of development and testing can be greatly improved, the cost is reduced, the route can be quickly changed, and the flexibility is high.
Further, based on the above embodiment, the generating the coordinate data of the additional GPS point between the two adjacent existing GPS points in the navigation route according to the preset vehicle speed, the preset transmission frequency of the coordinate data of the GPS point, and the coordinate data of the two adjacent existing GPS points specifically includes: acquiring distance information between two adjacent existing GPS points in the navigation route; obtaining the number of additional GPS points passing between the two adjacent existing GPS points when the vehicle runs along the navigation route according to the preset transmission frequency, the preset vehicle speed and the distance information; and obtaining coordinate data of the additional GPS points between the two adjacent existing GPS points according to the coordinate data of the two adjacent existing GPS points and the number of the additional GPS points passing between the two adjacent existing GPS points.
According to the preset transmission frequency and the preset vehicle speed, coordinate data of GPS points transmitted at intervals can be obtained, and according to the coordinate data of two adjacent GPS points, distance information between the two adjacent existing GPS points can be obtained, wherein the distance information is linear distance information. Therefore, it is possible to obtain how many additional GPS points can be arranged between the adjacent two existing GPS points, and the additional GPS points can be uniformly arranged according to a preset arrangement rule. Wherein the distance between two adjacent existing GPS points may be the same for two additional GPS points. The distance between an existing GPS point and an additional GPS point adjacent thereto may be different according to the difference in distance between adjacent two of the existing GPS points and the difference in arrangement rule.
On the basis of the embodiment, the embodiment of the invention obtains the coordinate data of the additional GPS points between the two adjacent existing GPS points by obtaining the number of the additional GPS points passing between the two adjacent existing GPS points, thereby improving the rapidity of generating the coordinate data of the additional GPS points.
Further, based on the above embodiment, the obtaining the coordinate data of the additional GPS point between the two adjacent existing GPS points according to the coordinate data of the two adjacent existing GPS points and the number of the additional GPS points passing between the two adjacent existing GPS points specifically includes: and obtaining the latitude and longitude offset of each additional GPS point relative to the previous GPS point according to the coordinate data of the two adjacent existing GPS points and the number of the additional GPS points passing between the two adjacent existing GPS points, and sequentially obtaining the coordinate data of the additional GPS points between the two adjacent existing GPS points according to the coordinate data of the existing GPS points passing first in the navigation route in the two adjacent existing GPS points and the latitude and longitude offset.
And obtaining the latitude and longitude offset of each additional GPS point relative to the previous GPS point according to the coordinate data of the two adjacent existing GPS points and the number of the additional GPS points passing between the two adjacent existing GPS points, wherein the previous GPS point refers to the previous GPS point passing along the direction from the preset starting point to the preset ending point, and the GPS points comprise the existing GPS points and the additional GPS points. For example, the last GPS point of the additional GPS point that the first passed between two adjacent existing GPS points is an existing GPS point, and the last GPS point of the remaining additional GPS points is an additional GPS point.
And sequentially obtaining the coordinate data of the additional GPS points between the two adjacent existing GPS points according to the coordinate data of the existing GPS points which pass through in the navigation route in the two adjacent existing GPS points and the longitude and latitude offset, so as to realize uniform arrangement of the additional GPS points. In the arrangement mode of the GPS points, the additional GPS points are sequentially obtained according to the longitude and latitude offset based on one of the two adjacent existing GPS points, which is closer to the preset starting point.
Based on the embodiment, the embodiment of the invention sequentially obtains the coordinate data of the additional GPS points between the two adjacent existing GPS points according to the coordinate data of the existing GPS points which are passed through first in the navigation route in the two adjacent existing GPS points based on the latitude and longitude offset, thereby realizing the rapid and simple acquisition of the coordinate data of the additional GPS points.
Further, based on the above embodiment, the method further includes: and converting the GPS route simulation data into standard GPS coordinate data and storing the standard GPS coordinate data into a coordinate file.
The GPS coordinates used by the vehicle-mounted terminal equipment to be tested are standard GPS coordinates, but because the third-party map software has a coordinate system of the third-party map software, the coordinate data of the existing GPS points and the additional GPS points obtained according to the existing GPS points, which are acquired by the third-party map software, cannot be directly used for testing, namely the GPS route simulation data cannot be directly used for testing, and the GPS route simulation data needs to be converted into standard GPS coordinate data.
After standard GPS coordinate data is obtained, it can be further saved into a coordinate file for testing.
On the basis of the embodiment, the GPS route simulation data are converted into standard GPS coordinate data and stored into the coordinate file, so that a precondition is provided for effective test.
Further, based on the above embodiment, the method further includes: and according to the preset transmission frequency, sequentially sending the coordinate data of the GPS points in the coordinate file to the vehicle-mounted terminal to be tested.
After the coordinate file is obtained, the coordinate file can be used for actual testing. According to the preset transmission frequency, the coordinate data of the GPS points in the coordinate file are sequentially sent to the vehicle-mounted terminal to be tested to simulate the process that the vehicle runs along the track formed by the GPS route simulation data to acquire the GPS data, and according to whether the track of the GPS route simulation data is a limited area and the distinguishing result of the vehicle-mounted terminal to be tested, the performance of the vehicle-mounted terminal to be tested can be tested.
On the basis of the embodiment, the embodiment of the invention sequentially sends the coordinate data of the GPS points in the coordinate file to the vehicle-mounted terminal to be tested according to the preset transmission frequency, thereby realizing the actual test and improving the practicability.
Further, based on the foregoing embodiment, the vehicle-mounted terminal to be tested includes a first vehicle-mounted terminal and a second vehicle-mounted terminal, and the transmitting, according to the preset transmission frequency, the coordinate data of the GPS point in the coordinate file to the vehicle-mounted terminal to be tested sequentially includes: the coordinate file is sent to a first vehicle-mounted terminal, and the first vehicle-mounted terminal sequentially sends the coordinate data of the GPS points in the coordinate file to the second vehicle-mounted terminal according to the preset transmission frequency; or the second vehicle-mounted terminal loads the coordinate file according to the preset transmission frequency, so that coordinate data of GPS points in the coordinate file are sequentially obtained; wherein the second in-vehicle terminal includes a display screen.
According to actual requirements, a first vehicle-mounted terminal and a second vehicle-mounted terminal are usually arranged in engineering vehicles such as a soil and slag vehicle, and the second vehicle-mounted terminal comprises a display screen. The first vehicle-mounted terminal can be provided with GPS equipment, GPS data are acquired when the vehicle actually runs and are sent to the second vehicle-mounted terminal, the second vehicle-mounted terminal displays the GPS data, whether the vehicle enters a restricted area is judged according to the GPS data, and if the vehicle enters the restricted area, an alarm and the like are given.
Therefore, during actual testing, the coordinate file may be sent to the first vehicle-mounted terminal, and the first vehicle-mounted terminal sequentially sends the coordinate data of the GPS point in the coordinate file to the second vehicle-mounted terminal according to the preset transmission frequency, so as to simulate a process that the second vehicle-mounted terminal actually acquires the GPS data. If the performance of the second vehicle-mounted terminal is to be tested directly, the coordinate file can also be loaded directly by the second vehicle-mounted terminal according to the preset transmission frequency, for example, the coordinate file is obtained and loaded through an external storage medium, so that the coordinate data of the GPS point in the coordinate file can be obtained in sequence.
On the basis of the embodiment, the coordinate data of the GPS points in the coordinate file are sequentially sent to the second vehicle-mounted terminal by the first vehicle-mounted terminal according to the preset transmission frequency by sending the coordinate file to the first vehicle-mounted terminal; or the second vehicle-mounted terminal loads the coordinate file according to the preset transmission frequency to test, so that the flexibility of the test is improved.

Fig. 3 is a schematic diagram of an existing GPS point obtained in the method for generating GPS route simulation data according to the embodiment of the present invention. Fig. 4 is a schematic diagram of GPS route simulation data obtained in the method for generating GPS route simulation data according to the embodiment of the present invention. The method for generating the GPS route simulation data according to the embodiment of the invention is further described below with reference to FIGS. 2 to 4.
The development and test efficiency needs to be improved in the prior art, and the development and test efficiency is improved by generating the GPS analog line. And simulating GPS data, and transmitting GPS point data according to the speed and time. The key point is that linear GPS point data is generated by fast routing. The first and second vehicle terminals may be enabled for use during testing.
The navigation route is searched out according to the route through the Goldmap, point coordinates in the route are obtained by using the Goldmap API, but GPS points in the Goldmap are not continuous points, namely, the GPS coordinates are only in the route with curves or radians, but the track of the GPS route is formed by continuous points, so that one GPS point information is required to be transmitted every second, and the positions of adjacent GPS points in the route are calculated according to the speed of the vehicle. And finally, forming a complete GPS track point set. As shown in fig. 2, a navigation route is first searched. Then, the coordinates of the route are obtained, the coordinates are given only when the route with corners or radians appears, only two ends of the straight line have coordinates, such as the star-shaped portion in fig. 3.
And calculating the distance between two points through coordinates of two adjacent GPS points, finally calculating how many GPS points are needed by the distance according to the vehicle speed, and then calculating the longitude and latitude needing to be offset every second, namely the longitude and latitude offset, and finally obtaining a track, as shown in fig. 4. However, the track obtained by the Goldmap cannot be directly used by the equipment, the equipment uses standard GPS point coordinates, and the Goldcalculation is offset, so that the track needs to be converted into standard GPS coordinate points. And finally, storing the coordinate set into a coordinate file for equipment to use. The first vehicle-mounted terminal obtains a GPS coordinate point every second according to time, sends the GPS coordinate point to the second vehicle-mounted terminal, or the second vehicle-mounted terminal loads the coordinate set by itself and displays the coordinate set on a display screen. As can be seen from fig. 4, the GPS point coordinates are uniformly distributed on the route, which can satisfy development and test use.
The Goldmap is loaded on line in a browser mode, so that the Goldmap can be developed through JavaScript, and on the basis of the above, the rest GPS points between the adjacent GPS points are calculated according to the principle.
