[0053] The embodiments of the present disclosure provide a map updating method, device and system. The preferred embodiments of the present disclosure are described below in conjunction with the drawings of the specification. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure. In addition, the embodiments and features in the embodiments of the present application can be combined with each other if there is no conflict.
[0054] The present disclosure provides a map updating method. Figure 1 As shown, the following steps are included:
[0055] S101, obtaining updated map data;
[0056] S102, determining a first area to which an update area corresponding to updated map data belongs;
[0057] S103, determining a first terminal device that meets the map update condition according to the acquired position relationship between the position of the terminal device and the first area;
[0058] S104: Push a map update notification to the first terminal device to control the first terminal device to complete the map update.
[0059] In the disclosed embodiment, the execution subject may be a server or a terminal, and the terminal may be a terminal other than the first terminal device. Optionally, the server may be a cloud control platform. The cloud control platform may provide detailed map data in the mining area, including road condition information and operation points, etc. At present, with the development of unmanned driving technology, many mines have adopted unmanned mining trucks on a large scale to perform automated transportation tasks. Nevertheless, manned vehicles are still an indispensable part of mining operations and continue to provide support for the production work of mines, including: command vehicles, map collection vehicles, watering vehicles, excavators, manned mining trucks, etc. These unmanned vehicles and manned vehicles operating in mining areas are usually equipped with a combined navigation device as a positioning module for obtaining location information, and are equipped with a communication device for communicating with the cloud control platform. In order to further improve the collaborative operation capability between unmanned vehicles and manned vehicles, terminal devices are usually configured for these vehicles. These terminal devices need to perform related operations according to the map display, such as performing tasks such as loading position creation and map inspection according to the map display. However, in the traditional terminal device map update mechanism, a full-area map update method is adopted, that is, whenever there is a map update in the operating area, all terminal devices will update the map data of the entire area. With the expansion of operating scenarios and the increase in vehicles, map updates in the operating area become more frequent, and terminal devices will also frequently update map data. This frequent update operation will put a lot of pressure on the terminal equipment, and it is easy to cause problems such as discontinuous map display and white screen, which will affect the staff's work execution and decision-making. In addition, when using a full-area map update method, a huge amount of data needs to be processed and transmitted during each map update process, which will occupy a large amount of network bandwidth, resulting in a decrease in data transmission speed and slow map updates, which will have a negative impact on the efficiency of production operations.
[0060] In the disclosed embodiment, the updated map data is first obtained. For example, the cloud control platform can obtain the map data in the mine collected by vehicles. These vehicles can be special vehicles such as map collection vehicles, or other vehicles used in production operations. According to these map data, the cloud control platform can update the map incrementally in real time, obtain the updated map data, and store and display it, so as to reflect the changes in the mine terrain in real time. For production operations in the mining area, the flat plate is usually divided into various areas. The area division can be carried out according to different needs. In a possible implementation, the area may include areas with different operating functions, such as loading areas, unloading areas, etc., to facilitate production operations and management scheduling. The area may also include road areas. There is no restriction on the division method of the area. The flat plate is a working platform for production in the mining area, which provides the necessary space for mining, transportation equipment, etc. When the map is updated, the entire area may be updated, or only part of the area within the area may be updated. Therefore, according to the updated map data, the first area to which the corresponding update area belongs can be determined.
[0061] Furthermore, the location of the terminal device is obtained, and a match is performed based on the location relationship between the location of the terminal device and the first area, and a first terminal device that meets the map update condition is determined based on the matching result, and a map update notification is pushed to the first terminal device. After receiving the notification, the first terminal device will obtain the updated map data, thereby controlling the first terminal device to complete the map update.
[0062] In the embodiment of the present application, the location information of the terminal device is obtained and accurately matched with the first area to which the map update area belongs. Based on the matching result, the terminal device is controlled to efficiently update the map data in a targeted manner. This method can accurately screen out the terminal devices that need to update the map, limit the area range of the map update, and reduce unnecessary update operations. It not only effectively solves problems such as discontinuity and white screen in the map display of the terminal device, but also avoids frequent processing and transmission of map data in the entire area, greatly saving network bandwidth and significantly improving the map update rate of the terminal device, thereby indirectly improving production operation efficiency.
[0063] In another embodiment of the present disclosure, Figure 2 As shown, in the above step S103, according to the acquired position relationship between the position of the terminal device and the first area, determining the first terminal device that meets the map update condition includes the following two situations:
[0064] Case 1: If the location is within the first area, the terminal device is determined to be the first terminal device that meets the map update condition;
[0065] Second case: if the first distance between the location and the first area is less than or equal to the first distance threshold, the terminal device is determined to be the first terminal device that meets the map update condition;
[0066] The first distance is the shortest distance from the location to the boundary of the first area.
[0067] In the embodiments of the present disclosure, for example, Figure 2 As shown in the figure, the positioning icon shows the positions of terminal device a, terminal device b, terminal device c, and terminal device d, and the black solid line area shows the positions of the first area 201, the first area 202, and the first area 203. The first area includes an operation area and / or a road area. For the first case above, the position of terminal device a is located in the first area 201, and the terminal device a is determined to be the first terminal device that meets the map update condition. For the second case above, the first distance between terminal device b and the first area 201 and the first area 203 is less than the first distance threshold, and the terminal device b is determined to be the first terminal device that meets the map update condition. The first distance between terminal device c and the first area 202 is less than the first distance threshold, and the terminal device c is determined to be the first terminal device that meets the map update condition. The first distance between terminal device d and the first area 201, the first area 202, and the first area 203 are all greater than the first distance threshold, and it is determined that terminal device d does not meet the map update condition. Among them, the above-mentioned first distance is the shortest distance from the position of the terminal device to the boundary of the first area.
[0068] In another embodiment of the present disclosure, it also includes:
[0069] Step 1: Obtain threshold determination information; the threshold determination information includes: the vehicle type of the vehicle to which the terminal device belongs and / or the area category corresponding to the first area;
[0070] Step 2: Determine a first distance threshold based on the threshold determination information.
[0071] In the disclosed embodiment, vehicles equipped with terminal devices include: command vehicles, mapping vehicles, water trucks, excavators, bulldozers, graders, refueling trucks, mining trucks, etc. Because these vehicles are of different types, their operating radius is also different, so the first distance threshold needs to be determined according to the vehicle type of the vehicle to which the terminal device belongs. In addition, the area corresponding to the first area may include: loading area, unloading area, road, etc. For example, an excavator needs to go to the loading area for mining operations. When the map of the loading area is updated, the map of the terminal device on the excavator needs to be updated in time to ensure the safety of the operation, so it is necessary to determine the first distance threshold according to the area category corresponding to the first area. Determining the first distance according to the vehicle type of the vehicle to which the terminal device belongs and / or the area category corresponding to the first area breaks the limitation of the flat area division and more flexibly and accurately determines the first terminal device that meets the map update conditions.
[0072] In another embodiment of the present disclosure, it also includes:
[0073] Obtain the first real-time speed of the vehicle to which the terminal device belongs;
[0074] In the above step S103, determining the first terminal device that meets the map update condition according to the acquired position relationship between the position of the terminal device and the first area includes:
[0075] When the first real-time vehicle speed is less than or equal to the first vehicle speed threshold, a first terminal device that meets the map update condition is determined according to a positional relationship between the position of the terminal device and the first area.
[0076] In the disclosed embodiment, before determining the positional relationship between the position of the terminal device and the first area, the terminal device may be subjected to speed screening, that is, the first real-time vehicle speed of the vehicle to which the terminal device belongs is obtained, and when the first real-time vehicle speed is less than or equal to the first vehicle speed threshold, the first terminal device that meets the map update condition is determined based on the positional relationship between the position of the terminal device and the first area. When the first real-time vehicle speed of the vehicle to which the terminal device belongs is low, the positional relationship between the position of the terminal device and the first area is determined to be more accurate, which is more conducive to the timely update of the terminal device map.
[0077] In another embodiment of the present disclosure, it also includes:
[0078] Obtain a second real-time speed of the vehicle to which the first terminal device belongs;
[0079] In the above step S104, pushing a map update notification to the first terminal device includes:
[0080] When the second real-time vehicle speed is less than or equal to the first vehicle speed threshold, a map update notification is pushed to the first terminal device.
[0081] In the disclosed embodiment, after determining the first terminal device that meets the position relationship, the first terminal device can be screened for vehicle speed, that is, the second real-time vehicle speed of the vehicle to which the first terminal device belongs is obtained, and when the second real-time vehicle speed is less than or equal to the first vehicle speed threshold, a map update notification is pushed to the first terminal device. When the second real-time vehicle speed is lower, the safety risk is lower, and map updates at this time are more conducive to ensuring the safe driving of safe vehicles.
[0082] In another embodiment of the present disclosure, it also includes:
[0083] Step 1: Obtain the first real-time speed of the vehicle to which the terminal device belongs;
[0084] Step 2: When the first real-time vehicle speed is greater than the first vehicle speed threshold, updated map data is sent to the terminal device according to a map update data acquisition request of the terminal device.
[0085] In the disclosed embodiment, the first real-time speed of the vehicle to which the terminal device belongs is obtained. When the first real-time speed is greater than a first speed threshold, the process of performing a map update will also occupy certain system resources of the terminal device, and there may be network delays. The map update efficiency will be lower than when driving at a low speed, and there may be potential safety hazards. Therefore, when the real-time speed is too high and the terminal device is actively triggered by a map update demand, updated map data can be sent to the terminal device based on the map update data acquisition request of the terminal device, which is more conducive to ensuring operational safety.
[0086] In another embodiment of the present disclosure, it also includes:
[0087] Determine the area category corresponding to the first area;
[0088] In the above step S103, determining the first terminal device that meets the map update condition according to the acquired position relationship between the position of the terminal device and the first area includes:
[0089] When the area category is a preset category, a first terminal device that meets the map update condition is determined according to the acquired position relationship between the position of the terminal device and the first area.
[0090] In the disclosed embodiment, the area category corresponding to the first area is determined. The area category corresponding to the first area includes production operation areas, such as loading areas, unloading areas, transportation road areas, etc., and also includes auxiliary production areas, such as maintenance areas, energy replenishment areas, water and electricity supply areas, office and living areas, etc. In some of these areas, even if the map is updated, it will not have a positive impact on production operations. First, the area category corresponding to the first area to which the update area belongs is determined. When the area category is a preset category, the first terminal device that meets the map update condition is determined based on the position relationship between the acquired terminal device and the first area. For example, if the area category corresponding to the first area to which the update area belongs is a loading area, and the reprinting area is a preset category, the first terminal device that meets the map update condition is determined based on the position relationship between the acquired terminal device and the loading area. If the area category corresponding to the first area to which the update area belongs is an energy replenishment area, the energy replenishment area is not a preset category, so the position relationship between the terminal device and the energy replenishment area is not judged. By dividing the area categories corresponding to the first area and setting preset categories, the frequency of terminal device map updates can be effectively reduced, thereby solving problems such as discontinuous and white screen display of terminal device maps and reducing network bandwidth resource consumption.
[0091] In another embodiment of the present disclosure, it also includes:
[0092] Obtain the location of the destination of the vehicle to which the terminal device belongs;
[0093] In the above step S103, determining the first terminal device that meets the map update condition according to the acquired position relationship between the position of the terminal device and the first area includes:
[0094] Step 1: Determine the driving path of the terminal device according to the acquired location of the terminal device and the location of the destination;
[0095] Step 2: Determine a first terminal device that meets the map update conditions based on the positional relationship between the driving path and the first area.
[0096] In the disclosed embodiment, the location of the destination of the vehicle to which the terminal device belongs is obtained, and the driving path of the vehicle to which the terminal device belongs is planned based on the obtained location of the terminal device and the location of the destination, the possible driving path of the vehicle to which the terminal device belongs is determined, and the first terminal device that meets the map update conditions is determined based on the positional relationship between the possible driving path and the first area. When the map is updated, the current location of the terminal device may be far away from the first area to which the update area belongs, and does not meet the map update conditions. However, the vehicle to which the terminal device belongs is moving, and the subsequent driving path may pass through the first area, or there is any point on the path that meets the map update conditions with the first area to which the update area belongs, then the terminal device needs to update the map. In this way, the vehicle to which the first terminal device belongs can control the first terminal device to complete the map update in advance before or on the way to the destination, thereby improving the map update efficiency and production efficiency of the first terminal device.
[0097] In another embodiment of the present disclosure, in the above step S102, determining the first area to which the update area corresponding to the updated map data belongs includes:
[0098] Acquire current map data; merge the updated map data with the current map data to obtain a first area to which the updated map data belongs; the updated map data includes tile data; and / or,
[0099] After pushing the map update notification to the first terminal device, the method further includes:
[0100] Step 1: receiving a request for obtaining updated map data sent by a first terminal device;
[0101] Step 2: Send the updated map data to the first terminal device so that the first terminal device completes the map update.
[0102] In the disclosed embodiment, the updated map data may include tile data, which is the updated map area divided into many small square pictures (tiles) according to certain rules, similar to using many small puzzle pieces to form a complete map. The size of these tiles is usually fixed, such as 256×256 pixels. Tile data has the advantages of fast loading, convenient caching, and adaptability to different types of devices and network conditions in map display. This division method can effectively improve the update, loading and display efficiency of the map. The tile data is merged with the current map data to generate a map update area, and then the first area to which the updated map data belongs is obtained.
[0103] Furthermore, the first terminal device can establish a communication connection and obtain map update data according to the received map update notification. After pushing the map update notification to the first terminal device, the cloud control platform receives the update map data acquisition request sent by the first terminal device and sends the updated map data to the first terminal device so that the first terminal device completes the map update. In this way, the first terminal device that urgently needs map update data can complete the map update in time.
[0104] Based on the same inventive concept, the embodiments of the present disclosure also provide a map updating device and system. Since the principles of the problems solved by these devices and systems are similar to those of the aforementioned map updating method, the implementation of the device and system can refer to the implementation of the aforementioned method, and the repeated parts will not be repeated.

[0108] In another embodiment of the present disclosure, the device map update push module 302 is used to determine the first terminal device that meets the map update condition according to the acquired position relationship between the position of the terminal device and the first area, including the following two situations:
[0109] Case 1: If the location is within the first area, the terminal device is determined to be the first terminal device that meets the map update condition;
[0110] Second case: if the first distance between the location and the first area is less than or equal to the first distance threshold, the terminal device is determined to be the first terminal device that meets the map update condition;
