Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
At the operation in-process of present unmanned aerial vehicle, the condition of transmission data interrupt often can appear, and control terminal can't present corresponding operation according to this corresponding transmission data control unmanned aerial vehicle to as for the unmanned aerial vehicle operation interrupt, lead to unmanned aerial vehicle operating efficiency lower.
The inventor researches and discovers that the existing unmanned aerial vehicle can generally adopt a microwave image transmission communication mode, an operator of the unmanned aerial vehicle can remotely control and watch real-time videos at the ground end in a sight distance range or adopt a 4G/5G cellular communication mode, or the transmission bandwidth of the microwave image transmission mode is large, the transmission precision requirement of the data is high, such as clear video data is transmitted, but the transmission distance is short, and the disconnection is easy after being shielded; although the 4G cellular network can be controlled remotely, the bandwidth is limited, the definition of transmitted real-time video is low, and the connection is easy to break in areas with poor signal coverage; although 5G can transmit large bandwidth video signals, the coverage is insufficient and industrial grade 5G chips are not mature.
Based on the above, the unmanned aerial vehicle communication method and device based on microwave image transmission and the cellular network provided by the embodiment of the invention can be used for switching to the communication mode with stronger signals for data transmission by acquiring and evaluating the signal intensity in real time, so as to ensure that the data transmission of the unmanned aerial vehicle is not interrupted, and further guarantee the operation efficiency of the unmanned aerial vehicle.
In order to facilitate understanding of the embodiment, a detailed description is first given of a method for unmanned aerial vehicle communication based on microwave mapping and a cellular network, which is disclosed in the embodiment of the present invention.
Fig. 1 is a schematic flow chart of an unmanned aerial vehicle communication method based on microwave mapping and a cellular network according to an embodiment of the present invention.
Referring to fig. 1, the method for communication of the unmanned aerial vehicle based on microwave mapping and cellular network is applied to the unmanned aerial vehicle device, and mainly comprises the following steps:
and step S102, acquiring microwave mapping signals and cellular network signals in real time.
The embodiment of the invention adopts corresponding base stations and other laying equipment to cover microwave and cellular networks to a certain range. Illustratively, the microwave pattern transmission signals can be collected through a microwave pattern transmission module of the unmanned aerial vehicle, and the cellular network module collects the cellular network signals.
The microwave mapping may be understood as a wireless transmission mode of data such as an image realized by a microwave technology.
And step S104, evaluating the microwave map transmission signal and the cellular network signal respectively to obtain a first signal intensity corresponding to the microwave map transmission signal and a second signal intensity corresponding to the cellular network signal.
It will be appreciated that the signal strength of the microwave mapping signal and the cellular network signal are evaluated separately herein.
Step S106, if the signal difference between the first signal strength and the second signal strength exceeds the preset signal strength threshold, switching to a target communication mode with higher signal strength of the first signal strength and the second signal strength for communication.
It should be noted that, the communication mode with the higher signal strength of the first signal strength and the second signal strength is taken as the target communication mode, and is switched to the target communication mode, for example, if the difference between the first signal strength and the second signal strength exceeds the preset signal strength threshold, and at this time, the first signal strength is higher than the second signal strength, the microwave pattern transmission mode corresponding to the first signal strength has a better effect, and is taken as the target communication mode, and is switched to this mode, and if the second signal strength is higher than the first signal strength, the process is similar to the above process, and is not repeated here.
It should be noted that the Signal strength of both the microwave mapping Signal and the cellular network Signal can be expressed by using a Reference Signal Receiving Power (RSRP), which is generally in the range of-105 dBm to-65 dBm. As an alternative embodiment, the preset signal strength threshold is 2dBm, and if the difference between the signal strengths of the two signals is greater than 2dBm, the transmission mode is switched to a better transmission mode.
In the preferred embodiment of practical application, based on the microwave map signal and the cellular network signal collected in real time, the signal intensities of the microwave map signal and the cellular network signal are evaluated respectively, the first signal intensity and the second signal intensity of the microwave map signal and the cellular network signal are compared, if the difference between the signal intensities of the microwave map signal and the cellular network signal is large and exceeds a preset signal intensity threshold value, the effect of the communication mode with the high signal intensity is considered to be good, the communication mode is determined to be a target communication mode, and the current communication mode of the unmanned aerial vehicle is switched to the target communication mode.
In some embodiments, step S104 may also be implemented by:
step 1.1), evaluating the microwave map signaling signal through a microwave map transmission module in the unmanned aerial vehicle to obtain a first signal intensity corresponding to the microwave map signaling signal.
And step 1.2), evaluating the cellular network signal through a cellular network module in the unmanned aerial vehicle to obtain a second signal intensity corresponding to the cellular network signal.
According to the embodiment of the invention, the microwave image transmission module and the cellular network module which are assembled in the unmanned aerial vehicle device respectively evaluate the respective signal intensity, and then the evaluated signal intensity result is sent to the control terminal, so that the follow-up operation is realized, and the computing power of the control terminal is saved.
In other embodiments, step S104 may also be implemented by:
step 2.1), the microwave map transmission signal is sent to a control terminal through a microwave map transmission module in the unmanned aerial vehicle, so that the control terminal evaluates and obtains a first signal intensity corresponding to the microwave map transmission signal;
and 2.2) sending the cellular network signal to a control terminal through a cellular network module in the unmanned aerial vehicle, so that the control terminal evaluates and obtains a second signal strength corresponding to the cellular network signal, wherein the microwave mapping module and the cellular network module do not have a signal evaluation function.
In a practical application scenario, in order to improve the reliability of signal transmission, the control terminal may evaluate the signal strengths of corresponding signals sent by the microwave image transmission module and the cellular network module again, and it is ensured that the identification evaluation result of the signal strength is more accurate.
In some embodiments, in order to save the power of the drone or the resources of the control terminal, frequent switching operations of the drone are not desired, and therefore, the method further includes:
and 3.1) if the first signal intensity and the second signal intensity are both within a preset signal intensity range, keeping the original target communication mode for communication.
Here, it should be noted that, in step S106, after the first signal strength and the second signal strength exceed the preset signal strength range and the difference between the two signal strengths exceeds the preset signal strength threshold, the communication mode is switched to the communication mode with the higher signal strength.
In some embodiments, before step S106, the method further includes:
step 4.1), determining a current communication mode to be selected according to the precision requirement of data transmission of the unmanned aerial vehicle;
the image or video data with high precision requirement needs to occupy larger transmission bandwidth, so that the microwave image transmission communication mode can be preferentially selected as the current communication mode to be selected. If the accuracy requirement of the transmitted data is more general, the cellular network communication mode can be used as the current communication mode to be selected.
And 4.2) judging whether the current communication mode to be selected is taken as the target communication mode or not based on the signal intensity corresponding to the current communication mode to be selected, and switching to the target communication mode.
For example, the signal strength level of the current communication mode to be selected is estimated to determine the target communication mode to be switched finally. According to the process of the foregoing embodiment, it can be determined whether the signal strength of the current communication mode to be selected is within a preset signal strength range; if yes, determining the current communication mode to be selected as a target communication mode, and switching to the target communication mode; if not, comparing the signal intensity of the current communication mode to be selected with the signal intensity of the rest communication modes (if the current communication to be selected is microwave map transmission, the rest communication modes are cellular networks, and vice versa), and selecting the communication mode with higher signal intensity as the target communication mode. It will be appreciated that priority is given to ensuring that the transmission of the communication signal is uninterrupted, as compared to being able to meet transmission accuracy requirements.
As an optional embodiment, in order to ensure that the transmission signal is not interrupted, when the precision requirement on the transmission data is also high, the method further includes:
and 5.1) if the precision requirement of the data transmitted by the unmanned aerial vehicle reaches a preset precision threshold value and the first signal intensity and the second signal intensity are within a preset signal intensity range, switching to a microwave image transmission communication mode with higher precision for communication.
In some practical applications, the method further comprises the following steps:
and 6.1) controlling corresponding operation of the unmanned aerial vehicle based on the unmanned aerial vehicle transmission data received by the target communication mode.
Wherein, control terminal can be according to the transmission data that this target communication mode received, control unmanned aerial vehicle flies to corresponding position, image acquisition or pesticide spraying etc. operation. The control terminal may be an intelligent terminal of a worker, a ground station control terminal, or a control device integrated in the control terminal, and the like, and may implement the control function in the embodiment of the present invention, which is not limited herein.

As an optional embodiment, the microwave map transmission communication can be preferentially used to ensure transmission of high-definition video data, when the unmanned aerial vehicle flies out of the microwave map transmission range or transmission of the microwave map is blocked due to physical shielding, the intensity of a microwave map transmission signal at the moment becomes low, the communication mode is automatically switched to a 4G/5G cellular network communication mode, and the transmission definition is adaptively reduced to meet the requirement of 4G/5G communication bandwidth and ensure the continuity of transmission data.
In addition, the embodiment of the invention ensures the normal transmission of the unmanned aerial vehicle signal by jointly using the 4G/5G cellular network and the microwave image transmission, also expands the operation range of the unmanned aerial vehicle, not only absorbs the advantage of high-definition image transmission in the high-definition image transmission range, but also utilizes the characteristic that the cellular network is not limited by distance, thereby improving the utilization value of the unmanned aerial vehicle.
