For describing the technical solutions of the present disclosure clearly, the following will briefly introduce the accompanying drawings used in the present disclosure. Obviously, for those of ordinary skill in the art, on the premise of not paying creative efforts, additional drawings can be derived from these drawings.
In order to make the purpose, technical solutions, and advantages of the embodiments of the present disclosure clear, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below, in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are some of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present disclosure.
With development of Internet, the fifth generation mobile communication technology (i.e., the 5th generation mobile network or the 5th generation wireless systems, abbreviated as 5G or 5D technology) is the latest generation of cellular mobile communication technology, and it is also an extension following 4G (e.g., LTE-A, WiMax), 3G (e.g., UMTS, LTE), and 2G (GSM) system. Performance goals of 5G includes high data rate, reduced latency, energy saving, cost reduction, increased system capacity, and large-scale device connectivity.
At the same time, a technical solution of the present disclosure also adopts a communication mode of Wi-Fi 6 to realize the communication between aircraft.
Wi-Fi 6 (formerly known as 802.11.ax) is the sixth generation of wireless network technology and is a name of the Wi-Fi standard. Wi-Fi 6 is a wireless local area network technology created by the Wi-Fi Alliance based on the IEEE 802.11 standard. Wi-Fi 6 mainly adopts technologies such as Orthogonal Frequency Division Multiple Access (OFDMA), Multi-User Multiple-Input Multiple-Output (MU-MIMO) etc. The MU-MIMO technology allows a router to communicate with multiple devices simultaneously instead of sequentially. For example, the MU-MIMO technology allows the router to communicate with four devices simultaneously, and Wi-Fi 6 allows the router to communicate with eight devices.
As shown in
Step 201: broadcasting signaling messages including a physical device identification of the target aircraft by the 5G signal base station;
Step 202: obtaining a feedback message of the target aircraft;
Step 203: determining an antenna array unit, of a plurality of antenna array units, required to communicate with the target aircraft based on the feedback message;
Step 204: transmitting communication information to the target aircraft by the antenna array unit; the communication information includes control information of a plurality of aircraft in a target aircraft group;
Step 205: receiving the communication information by the target aircraft; and
Step 206: respectively transmitting the control information in the communication information to corresponding aircraft in the target aircraft group by Wi-Fi 6.
The broadcast may be a broadcast directed towards various directions. Each of the plurality of antenna array units of the 5G signal base station is integrated with a plurality of antenna units. The plurality of antenna units broadcast signals in various directions. The signaling messages refer to messages configured to control a communication process of the target aircraft. The physical device identification refers to an identification used to distinguish the target aircraft from the other aircraft (i.e., the other aircraft in the target aircraft group except for the target aircraft). The physical device identification may be a Media Access Control (MAC) address of a device such as a processor on the target aircraft, or other identifications, as long as the target aircraft is able to be distinguished.
Since the target aircraft is the logistics-specific aircraft configured to transport items, which does not need to fly at a high altitude, the target aircraft flies at a low altitude and be close to the 5G signal base station and receives the one of the signaling messages transmitted by the 5G signal base station. The target aircraft transmits the feedback message after receiving the one of the signaling messages transmitted by the 5G signal base station. The feedback message includes an identification of the antenna array unit.
Since the feedback message includes the identification of the antenna array unit, it is determined that which antenna array unit of the plurality of antenna array units is communicated with the target aircraft according to the feedback message.
After the antenna array unit is determined, the antenna array unit is configured to transmit the communication information to the target aircraft.
The control information in the communication information controls flight processes of the plurality of aircraft in the target aircraft group. The target aircraft group includes the target aircraft and the other aircraft in the adjacent area of the target aircraft. The control information may be control information on a flight speed, a flight altitude, or a flight direction of a certain aircraft.
The target aircraft acts as a router in the target aircraft group. The target aircraft may set itself as a Wi-Fi hotspot supporting a Wi-Fi 6 communication mode. After the target aircraft receives the communication information, the target aircraft transmits the communication information to the corresponding aircraft respectively by the Wi-Fi 6 communication mode.
In some embodiments, each control information in the communication information includes an aircraft equipment identification corresponding to a corresponding aircraft. Each aircraft equipment identification is included in the communication information in a predetermined communication protocol format. After the target aircraft receives the communication information, the target aircraft identifies each control information for the corresponding aircraft in the target aircraft group according to the predetermined communication protocol and each corresponding aircraft equipment identification. Then, the target aircraft transmits the control information of each of the plurality of aircraft to the corresponding aircraft through the predetermined communication protocol with the aircraft by means of Wi-Fi 6.
In some embodiments, before the step of broadcasting the signaling messages including the physical device identification of the target aircraft by the 5G signal base station, the communication method further includes following steps:
The step of broadcasting the signaling messages including the physical device identification of the target aircraft by the 5G signal base station includes:
In some embodiments, the server may be a server in the communication network responsible for providing services for the 5G signal base station. The server is able to obtain the location information of each of the plurality of aircraft. The location information of each of the plurality of aircraft may represent by a two-dimensional plane coordinate or a three-dimensional space coordinate. The signal range of the 5G signal base station may also be represented by another two-dimensional plane coordinate or another three-dimensional space coordinate. The location information of each of the plurality of aircraft and the signal range of the 5G signal base station are preferably represented by three-dimensional space coordinates. It should be noted that, since the target aircraft is configured as the aircraft for logistics transportation, and transported items are generally scattered and small, therefore, the flight altitude of the target aircraft is low. Thus, the target aircraft is able to communicate with the 5G signal base station through the 5G signals.
In some cases, the target aircraft only receive the one of the signaling messages in one direction. After the target aircraft receives the one of the signaling messages, the communication method further includes:
The step of determining the antenna array unit, of the plurality of antenna array units, required to communicate with the target aircraft based on the feedback message includes:
In some embodiments, before the step of broadcasting the signaling messages including the physical device identification of the target aircraft by the 5G signal base station, the communication method further includes:
In some embodiments, the remaining battery information represents a flight power output by each of the plurality of aircraft according to remaining battery thereof. Alternatively, according to the remaining battery information, the flight power output by each of the plurality of aircraft is calculated based on the remaining battery of each of the plurality of aircraft.
There are many ways to determine the target aircraft, but one preferred principle is that the remaining battery of the target aircraft is greater than the battery energy to be consumed by the target aircraft.
As the target aircraft, it actually serves as the router for the other aircraft in the target aircraft group. Since the target aircraft should be served as the router, the target aircraft consumes more power. Therefore, when determining the target aircraft, one of the plurality of .aircraft with highest remaining battery is selected first.
In some embodiments, a step of calculating the information of the battery energy to be consumed by each of the plurality of aircraft based on the remaining flight route information of each of the plurality of aircraft includes:
In some embodiments, a step of calculating the energy required by each of the plurality of aircraft to complete the remaining flight route, according to the windage pressure and the flight speed of each of the plurality of aircraft; includes:
calculating power P0 required by each of the plurality of aircraft to complete the remaining flight route by a formula of F1*v1+F2*sin α*v2+P (formula (1)).
In the formula (1), v1 is the flight speed of each of the plurality of aircraft, and F1 is a forward direction resistance of each of the plurality of aircraft; v2 is a wind speed, and F2 is a lateral windward resistance of each of the plurality of aircraft; a is an angle between an opposite direction of forward motion of each of the plurality of aircraft and a wind direction, and, P is a hovering power of each of the plurality of aircraft.
It should be noted that, each of the plurality of aircraft includes a plurality of pressure sensors. The plurality of pressure sensors may be arranged on an outer side of each of the plurality of aircraft. In some embodiments, the plurality of pressure sensors of each of the plurality of aircraft include a first pressure sensor towards a forward direction of a corresponding aircraft, second pressure sensors towards a direction perpendicular to the forward direction of the corresponding aircraft (i.e., the second pressure sensors may be arranged on a left side and a right side of the corresponding aircraft), a third pressure sensor towards a rear direction of the corresponding aircraft. The plurality of pressure sensors each senses a wind force on a surface thereof. A conversion relationship between the wind force sensed by the plurality of pressure sensors and the wind force subjected to the corresponding aircraft under in corresponding directions is determined in advance, according to a surface area of each of the plurality of pressure sensors and a windward area of the corresponding aircraft in a corresponding direction. According to the conversion relationship, the force on the corresponding aircraft in the corresponding direction is calculated according to the wind force sensed by a corresponding pressure sensor of the plurality of pressure sensors.
The hovering power of each of the plurality of pressure sensors is determined according to a quantity of engine revolutions of a main propeller of each of the plurality of pressure sensors. In practical applications, the hovering power of each of the plurality of pressure sensors corresponding to different revolutions is recorded in a data sheet. The hovering power of each of the plurality of pressure sensors can be looked up in the data sheet according to the quantity of revolutions.
In some embodiments, a direction of the wind speed and a direction of the wind force are the same, and a vector component of the wind speed v2 in a lateral direction is sin α*v2. During the flight of each of the plurality of aircraft 303, each of the plurality of aircraft 303 basically flies along the forward direction, and each of the plurality of aircraft 303 does not fly along the lateral direction. Since each of the plurality of aircraft 303 does not fly along the lateral direction, power prevents each of the plurality of aircraft 303 from flying along the lateral direction is F2*sin α*v2. Power of each of the plurality of aircraft 303 flying in the forward direction is F1*v1. During the flight, each of the plurality of aircraft 303 flies in the air, each of the plurality of aircraft 303 has a hovering power P. In summary, the formula F1*v1+F2*sin α*v2+P is utilized to calculate the power P0 required by each of the plurality of aircraft to complete the remaining flight route of each of the plurality of aircraft.
In some embodiments, after obtaining the power P0 required to complete the remaining flight route of ach of the plurality of aircraft, the energy W required by each of the plurality of aircraft is obtained by multiplying a time t required by each of the plurality of aircraft with P0 to complete the remaining flight route of each of the plurality of aircraft. It should also be noted that the above calculation process is a relatively simplified formula adopted to improve a calculation efficiency and a calculation speed. When the wind force changes greatly, an integration method can also be used to calculate the power at each time according to a predicted wind speed and a wind force at each time, and a plurality of power are integrated according to a time t, thereby obtaining more accurate energy values.
After the energy W required by each of the plurality of aircraft is obtained, the battery energy to be consumed by each of the plurality of aircraft is calculated by a formula of W/ε. W is the energy required by each of the plurality of aircraft to complete the remaining flight route of each of the plurality of aircraft, and ε is a battery energy conversion coefficient of each of the plurality of aircraft.
In some embodiments, it is assumed that the battery energy conversion coefficient of each of the plurality of aircraft is 80%, and the energy W required by each of the plurality of aircraft is 10 kWh, the battery energy to be consumed by each of the plurality of aircraft is calculated as 12.5 kWh according to the above formula.
It should be pointed out that, the above-mentioned determination method for the target aircraft is only one of a plurality of determination methods. In some embodiments, the main principle is to determine the one of the plurality of aircraft whose remaining battery is greater than the battery energy to be consumed as the target aircraft.
In some embodiments, if the remaining battery of each of the plurality of aircraft is greater than the battery energy to be consumed by each of the plurality of aircraft, the one of the plurality of aircraft with the highest remaining battery is determined as the target aircraft.
The target aircraft is optionally an aircraft provided with a solar panel. The communication method further includes following steps:
In some embodiments, the optimal energy absorption azimuth angle may be an angle that makes the light energy absorption surface of the solar panel face an incident angle of sunlight. When the solar panel is adjusted to the optimal energy absorption azimuth angle, the incident angle of the sunlight is perpendicular to the light energy absorption surface of the solar panel.
The location coordinate of the target aircraft may be a three-dimensional space coordinate including altitude information. The time zone where the target aircraft is located is determined according to the location coordinate of the target aircraft. In the time zone, a location coordinate of the sun is determined according to a specific time. Further, the optimal energy absorption azimuth angle is determined according to the location coordinate of the sun and the location coordinate of the target aircraft.
