In the related technology, the communication between the detection equipment and the terminal and the wireless communication between the unmanned aerial vehicle body and the ground control remote controller are separated. The detection equipment and the terminal need to communicate bidirectionally. The detection equipment frequently sends data packets containing a large amount of mineral data to the terminal, and the terminal needs to feed back after each time the detection equipment sends a data packet.

[0038] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of the present application.

Instead, the use of the terms "example", "exemplary", and the like, is intended to present the concept in a specific manner.

[0040] Under the background of rapid development of contemporary unmanned aerial vehicle technology, its application scenarios have developed from traditional aerial photography to surveying and mapping of geological resources, which puts forward high requirements for the communication link between the unmanned aerial vehicle and the ground control system. Not only the position, attitude and other key state data of the unmanned aerial vehicle need to be transmitted in real time, but also the immediate response of the control command is required. In the related technology, the detection device and the terminal need to communicate bidirectionally during the mineral detection process. The detection device frequently sends data packets to the terminal, and the terminal needs to feedback after the detection device sends a data packet each time. The large amount of data in each data packet sent by the detection device will result in large amount of communication data of the detection device, transmission delay, and untimely communication, which will increase the power consumption of the detection device and affect the detection precision.

[0041] The defects of the above solutions are the results of the inventors after practice and careful research, therefore, the discovery process of the above problems and the solutions proposed by the present disclosure to solve the above problems in this paper should be the contribution of the inventors to the present disclosure in the process of the present disclosure.

[0042] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0043] Some embodiments of the present application will be described in detail below with reference to the drawings. In the case of no conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0044] As Figure 1 shown, at least one disclosed embodiment provides a geological data communication system, comprising: two unmanned aerial vehicle devices, and a plurality of terminals; the terminals are dispersedly arranged in a to-be-tested region; the unmanned aerial vehicle device comprises: an unmanned aerial vehicle body and a detection device; the detection device is mounted on the corresponding unmanned aerial vehicle body; the detection device and each terminal are in wireless communication; the unmanned aerial vehicle body is configured to drive the detection device to move in the to-be-tested region to scan the to-be-tested region to collect mineral data; the detection device is configured to send normal data packets to each terminal, and send a modified data packet to each terminal when a mineral is detected, the modified data packet is smaller than the normal data packet, thereby realizing that the size of the data packet that needs to be sent to the terminal can be reduced after the mineral data is detected, and the mineral data can be sent more quickly and conveniently.

[0045] In this embodiment, when any unmanned aerial vehicle body fails, both unmanned aerial vehicle bodies stop flying for maintenance.

[0046] In this embodiment, the range of the to-be-tested region is large, and a single terminal or a small number of terminals cannot ensure continuous communication between the unmanned aerial vehicle body and the terminal in the to-be-tested region, resulting in that the unmanned aerial vehicle body cannot continuously send corresponding data packets, so a plurality of terminals are arranged.

[0047] In this embodiment, by arranging two unmanned aerial vehicle devices, when one unmanned aerial vehicle device first judges that there is a mineral, the other unmanned aerial vehicle device can be controlled to more accurately judge the range of the mineral existing region.

[0048] In this embodiment, the detection device and the terminal can communicate through 5 G and the like.

[0049] In this embodiment, the unmanned aerial vehicle body can automatically fly.

[0050] In this embodiment, the unmanned aerial vehicle body can communicate wirelessly with the corresponding ground control remote controller for manual control.

[0051] In this embodiment, the detection device can be an FS60-unmanned aerial vehicle hyperspectral measurement system, a domestic GB -4 A helium light pump magnetometer, etc., and the detection device can directly communicate wirelessly with each terminal, and the amount of data obtained per second is greater than 5 G peak value of data transmission per second.

[0052] In an optional embodiment, the normal data packet comprises: a start symbol, a device ID , a state bit, a signal strength, a terminal ID, a package serial number, a reserved bit, a check bit and an end symbol; the modified data packet comprises a start symbol, a device ID , a package serial number, a reserved bit and an end symbol; when mineral data is detected, the mineral data and the corresponding coordinate point are stored in the reserved bit; the start symbol has a corresponding unique code when the detection device detects different types of minerals.

[0053] In the embodiment, the code in the start symbol can correspond to no mineral, AC AD can correspond to iron ore, AE can correspond to tin ore, etc.

[0054] In the embodiment, the information corresponding to each position field in the data packet is shown in the following table:

[0055] Table 1: Character information table

[0056]

[0057] In the embodiment, 0 x The prefix is used to explicitly identify that the subsequent character is a hexadecimal number.

[0058] In the embodiment, when the detection device judges that there is a mineral, the state bit, signal strength, device ID , check bit, etc. in the original normal data packet can be removed, so that the size of the modified data packet is smaller than that of the modified data packet, which is more convenient for the rapid transmission of the modified data packet, reduces the communication consumption between the detection device and the terminal, and avoids affecting the detection accuracy of the detection device.

[0059] In the embodiment, the terminal can communicate with the upper computer, and the received modified data packet and normal data packet are transmitted to the upper computer. The upper computer marks the mineral area on the map according to the data of the modified data packet and the normal data packet, and draws a mineral map.

[0060] In the embodiment, the normal data packet can be: AC 05 00 75 A 8 0 F **** FC 3 C ; the modified data packet after detecting iron ore can be: AD 05 0 F 0 x 2 EE 0 3 C ; the modified data packet when no mineral is detected can be: AC 05 0 F **** 3 C After detecting the mineral, **** can adopt, for example, 0 x 2​EE 0 is replaced by hexadecimal.

[0061] In this embodiment, the **** character segment can be adjusted in size as needed, can be specific mineral data, and latitude and longitude data.

[0062] In an optional implementation, the detection device is configured to acquire signal strengths between each terminal and the detection device, sort each terminal according to the corresponding signal strength from large to small, select a terminal with a signal strength greater than a preset strength according to the signal strength, and acquire a size of a one-time data amount of the terminal with the smallest signal strength among the selected terminals as a standard data amount. A normal data packet or a modified data packet is divided according to the standard data amount, so that the size of the data amount of each data packet after division is the size of the standard data amount.

[0063] In this embodiment, dividing a normal data packet or a modified data packet according to the standard data amount can reduce the transmission time required by a single divided data packet, and reduce the impact of the electromagnetic wave used by the detection device to detect minerals on the communication of the data packet.

[0064] In this embodiment, the detection device can send a handshake data packet to the terminal with a signal strength greater than the preset strength, and the terminal can send the size of the one-time data amount of the corresponding terminal to the detection device upon receiving the handshake data packet.

[0065] In an optional implementation, the detection device is configured to send the divided data packets from the terminal with the smallest signal strength among the selected terminals one by one, and the sum of the corresponding standard data amounts of the data packets received by each selected terminal except the terminal with the largest signal strength among the selected terminals is less than or equal to the size of the one-time data amount of the corresponding terminal. If the selected terminals have all received the data packets, and there are still divided data packets of a normal data packet or a modified data packet that have not been sent to the terminals, the remaining data packets are sent to the terminal with the largest signal strength among the selected terminals.

[0066] In this embodiment, when sending the divided data packets to the terminal with the smallest signal strength, the data packets required by the terminal with a larger signal strength can be integrated according to the number of data packets required by the terminal with a larger signal strength, so as to facilitate the transmission of the data packets required by the terminal with a larger signal strength directly after the corresponding divided data packets of the terminal with a smaller signal strength are sent, and improve the transmission speed.

[0067] In an optional implementation, the terminal is configured to feed back a receiving signal to the corresponding detection device after receiving the divided data packets of the normal data packet; and the terminal is further configured not to feed back a receiving signal to the corresponding terminal after receiving the divided data packets of the modified data packet.

[0068] In this embodiment, the size of a normal data packet or a corrected data packet can be 200 MB, through 5 G Communication can include mineral data, such as obtaining terrain information by measuring the spectral image information of plants, water bodies, soil and other ground features in real time. The time required to transmit a normal data packet or a data packet divided into modified data packets is relatively short. At this time, the flight distance of the UAV itself is relatively short, which is convenient for complete exploration of the area to be explored.

[0069] In this embodiment, both a normal data packet and a modified data packet contain coordinate location information to facilitate the subsequent drawing of a mineral map. Mineral areas can be marked on the mineral map based on the coordinate location information.

[0070] In this embodiment, the presence and type of minerals can be determined based on the start symbol.

[0071] like Figure 2 As shown, in one optional implementation, the UAV body is configured to move the corresponding detection device, and during the movement of the detection device, it sends normal data packets and correction data packets to each terminal. One of the UAV bodies is configured to store a preset route, and initially, the UAV body can follow... Figure 2 middle F The drone body serves as the initial drone body. The preset route consists of several equidistant parallel horizontal segments. The ends of adjacent horizontal segments are connected only by a vertical segment, and the distance between adjacent horizontal segments is less than or equal to the diameter of the scanning range of the detection device. The initial drone body flies along the stored preset route. When the detection device detects a mineral, the detection device sends a spiral flight signal to the drone body. The initial drone body then begins spiral flight with the location of the mineral detected by the detection device as the starting point.

[0072] In this embodiment, after the initial UAV body flies according to the preset route, the scanning range of the detection equipment can cover the entire area to be detected, making mineral detection more accurate.

[0073] like Figure 3As shown in the figure, in an optional embodiment, when the initial unmanned aerial vehicle body flies along the spiral line, if none of the detection devices detects the mineral within the preset time, the detection device judges that the initial unmanned aerial vehicle body ends the spiral flight and sends a flight signal to the initial unmanned aerial vehicle body, or the initial unmanned aerial vehicle body judges that the spiral flight ends when the spiral line corresponding to the path ends, the initial unmanned aerial vehicle body continues to fly along the preset route after flying to the intersection farthest from the preset route in the forward direction of the spiral line of the initial unmanned aerial vehicle body, and the detection device re-sends normal data packets to each terminal; the terminal is configured to feed back a correction data packet receiving completion signal to the detection device after receiving the normal data packet re-sent by the detection device, a receiving signal corresponding to the normal data packet, and a take-off detection signal to another unmanned aerial vehicle body, and the unmanned aerial vehicle body receiving the take-off detection signal flies to the starting point for spiral flight.

[0074] In this embodiment, the path of the spiral flight of the initial unmanned aerial vehicle body can be preset in the initial unmanned aerial vehicle body, and the maximum diameter of the spiral flight path is half of the diameter of the scanning range of the detection device.

[0075] In this embodiment, Figure 3 The solid line in the figure corresponds to the spiral line of the initial unmanned aerial vehicle body, and the dashed line corresponds to the spiral flight path of the next unmanned aerial vehicle body.

[0076] In an optional embodiment, the spiral line density corresponding to the other unmanned aerial vehicle body is more dense than the spiral line corresponding to the initial unmanned aerial vehicle body, that is, the radial distance between adjacent two spiral lines in the spiral line corresponding to the other unmanned aerial vehicle body is half of the radial distance between adjacent two spiral lines in the spiral line corresponding to the initial unmanned aerial vehicle body.

[0077] In this embodiment, the maximum diameter of the spiral flight path corresponding to the other unmanned aerial vehicle body is half of the diameter of the scanning range of the detection device.

[0078] In this embodiment, after the spiral flight of the initial unmanned aerial vehicle body ends, the next unmanned aerial vehicle body can perform spiral flight with a smaller spiral line radius change, and more accurately detect the mineral area. After the spiral flight path corresponding to the other unmanned aerial vehicle body ends, the unmanned aerial vehicle body lands and stops to wait for the next flight.

[0079] As Figure 4 shown in the figure, in this embodiment, after the spiral flight of the initial unmanned aerial vehicle body ends, the other unmanned aerial vehicle body starts spiral flight with the same starting point. Since the spiral line density corresponding to the other unmanned aerial vehicle body is more dense than the spiral line corresponding to the initial unmanned aerial vehicle body, more accurate detection can be achieved.

[0080] In an alternative embodiment, the other unmanned aerial vehicle bodies, in addition to the initial unmanned aerial vehicle body, send correction data packets to the terminals when performing spiral flight.

[0081] At least one other disclosed embodiment also provides a working method using the above geological data communication system, comprising: the unmanned aerial vehicle body driving the detection device to move in the to-be-measured area to scan the to-be-measured area to collect mineral data; the detection device sending normal data packets to the terminals and sending correction data packets to the terminals when detecting minerals, the correction data packets being smaller than the normal data packets.

[0082] To sum up, the geological data communication system comprises: two unmanned aerial vehicle devices and a plurality of terminals; the terminals are dispersedly arranged in the to-be-measured area; the unmanned aerial vehicle device comprises an unmanned aerial vehicle body and a detection device; the detection device is mounted on the corresponding unmanned aerial vehicle body; the detection device and each terminal are in wireless communication; the unmanned aerial vehicle body is configured to drive the detection device to move in the to-be-measured area to scan the to-be-measured area to collect mineral data; the detection device is configured to send normal data packets to the terminals and send correction data packets to the terminals when detecting minerals, the correction data packets being smaller than the normal data packets, thereby realizing that the size of the data packets that need to be sent to the terminals can be reduced after detecting mineral data, and the mineral data can be sent more quickly and conveniently.

[0083] In the description of the embodiments of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting" should be understood in a broad sense, for example, can be fixed connection, can also be detachable connection, or integrally connected; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium, can be the communication inside two elements.

In addition, terms such as "first", "second" and other numerical terms are used herein, unless otherwise explicitly indicated herein. Therefore, the first element, component, region, layer or section discussed above can be referred to as the second element, component, region, layer or section without departing from the teachings of the example embodiments.

Spatially relative terms can be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the example term "below" can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0086] In the above discussion, unless otherwise stated, the terms "about," "approximately," "substantially" and the like mean a + / - 10% variation from the value being discussed.
