Abstract
Description
Technical Field
[0001] The invention belongs to the field of oil field GPS navigation, and in particular relates to an oil field GPS navigation engine generation method, system, equipment and storage medium. Background Art
[0002] With the development of oil exploration technology, people have discovered a large amount of oil, natural gas and other resources in mountainous areas, deserts and other uninhabited areas. However, there are some problems with navigation technology in oil fields, such as untimely updates and low accuracy. The basic data update frequency of navigation products on the market is generally low in uninhabited areas such as mountainous areas and deserts, which is far from meeting the needs of production and construction. In order to solve these problems, it is necessary to develop an engine that is more suitable for oil field navigation.
[0003] The navigation technology currently on the market is mainly based on road network data, but there are few basic roads in the oil fields, and very few basic roads can directly reach the mining platform, so traditional navigation technology does not perform well in these areas. In order to improve navigation capabilities in oil fields, we need to adopt more advanced technologies to assist navigation systems to provide more accurate navigation information.
[0004] However, even if the most advanced technology is used to obtain the corresponding oil field data, there is still a problem, that is, this data may not be the latest. For example, due to the needs of production and construction, a large number of new oil wells and gas wells are developed every year, which will generate a large number of newly opened roads. These roads belong to the oil field production and need to be developed independently, not in a unified planned development. Therefore, it is generally difficult to be updated in traditional navigation technology, resulting in errors in the navigation process, affecting the overall work efficiency, and failing to meet the needs of oil field production and construction. Therefore, we need a technology that can update road data in a timely manner to ensure the accuracy of navigation. Summary of the invention

If the difference is less than the preset distance, output the current path point; otherwise, continue to extract the next path point on the initial path, and superimpose the path point on the main engine sub-path, and repeat S202 until the current path point is output.
[0020] Furthermore, the preset distance is 1 km.

[0065] The present invention will be further described below in conjunction with the embodiments and drawings:
[0066] Example
[0067] In order to solve the problem mentioned in the background technology: it is generally difficult to update in traditional navigation technology, resulting in errors in the navigation process, affecting the overall work efficiency, and failing to meet the needs of oil field production and construction.
[0068] Therefore, this embodiment provides a method for generating a GPS navigation engine in an oil field. Based on traditional navigation technology, this method combines local oil field GPS vehicle trajectory data (local data) to develop an engine suitable for oil field navigation, so as to solve the problem that traditional navigation technology cannot navigate the last kilometer in the oil field due to low data update frequency, and finally meet the needs of oil field production and construction.
[0069] like Figure 1 As shown, this embodiment provides a method for generating an oilfield GPS navigation engine, and the specific steps are as follows:
[0070] The navigation path between the starting point and the end point is calculated through the AutoNavi navigation engine interface (hereinafter referred to as the "AutoNavi initial path");
[0071] Extract the path points in the Amap initial path in sequence, combine the path points with the navigation starting point, obtain a new sub-path (hereinafter referred to as the "Amap sub-path"), and calculate the length of the Amap sub-path;
[0072] Calculate the difference between the length of the Amap initial path and the length of the Amap sub-path;
[0073] If the difference is greater than one kilometer, the next path point in the Amap initial path is extracted and superimposed onto the Amap sub-path. The length difference between the Amap initial path and the Amap sub-path is compared again.
[0074] When the difference between the two paths is less than one kilometer, the local navigation path is calculated;
[0075] The end point of the Amap sub-path is used as the starting point for calculating the local data (local mountain trail data), and the navigation path of the local data (hereinafter referred to as the "local sub-path") is calculated;
[0076] Compare the distance difference between the endpoint of the initial path of Amap and the endpoint of the local sub-path and the actual destination;
[0077] If the distance between the end point of the Amap initial path and the real destination is less than the distance between the end point of the local sub-path and the real destination, the Amap initial path will be directly used as the final navigation path;
[0078] If the distance between the end point of the Amap initial path and the real destination is greater than the distance between the end point of the local sub-path and the real destination, the Amap sub-path and the local sub-path are concatenated to obtain the final navigation path.
[0079] It should be noted that the above local data are historical data obtained through field surveys. These historical data are stored in a local database. Different local databases will be established for different regions for subsequent development work.
[0080] like Figure 2 As shown, specifically Figure 2 (a) and Figure 2 (b) Figure 2 (a) is a screenshot of the Amap APP. Figure 2 (b) is a screenshot of the oil field GPS navigation engine obtained by using the method provided in this embodiment; it can be seen that when searching for the same oil well, Amap can only find the location closest to the destination, but the location is actually located on the north side of Aodong Expressway, and the destination is located on the south side of Aodong Expressway; the method provided in this embodiment can correctly guide the vehicle to cross the Aodong Expressway through the underpass of the expressway and finally arrive at the oil well located on the south side of Aodong Expressway; thereby solving the technical problem in the existing oil field navigation that navigation cannot be performed within a certain distance due to the low frequency of data update.
[0081] In summary, this embodiment provides a method for generating a GPS navigation engine in an oil field, which has the following advantages over existing navigation technologies:
[0082] The method uses the oil field as the destination for navigation, obtains the initial path, selects the path point on the initial path, outputs the path point corresponding to the difference between the initial path and the main engine sub-path that is less than the preset distance through calculation and judgment, uses the path point as the starting point of local navigation data, calculates and outputs the local sub-path of the oil field, and then respectively calculates the distance from the end point of the initial path and the end point of the local sub-path to the real destination and judges the two. If the distance from the end point of the initial path to the real destination is small, the initial path is output as the final navigation path; otherwise, the main engine sub-path is spliced with the local sub-path to obtain the final navigation path, thereby realizing accurate navigation of the oil field, overcoming the problem that the traditional navigation technology cannot navigate the last certain distance in the oil field due to the low frequency of data update, improving the overall work efficiency, and meeting the needs of production and construction in the oil field.
[0083] The above embodiment is only one of the implementation methods that can realize the technical solution of the present invention. The scope of protection claimed by the present invention is not limited only to this embodiment, but also includes changes, replacements and other implementation methods that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the present invention.
