Description

Communication method and device and unmanned aerial vehicle

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a communications method, an apparatus, and an unmanned aerial vehicle.

Background

In the field of communications, firmware upgrade is performed according to a certain communication mechanism based on radio frequency communication between radio frequency transceiver devices (radio frequency transmitter device, radio frequency receiver device). Different versions of the radio frequency transceiver employ different communication mechanisms. In the process of upgrading firmware, if the upgrade is suddenly stopped for some reason, it may happen that one of the rf transmitting end and the rf receiving end is successfully upgraded, while the other end is failed to upgrade, the end that is successfully upgraded will use the new communication mechanism, while the end that is not yet successfully upgraded still uses the old communication mechanism. In this case, when the radio frequency transceiver is restarted to continue to complete the upgrade, the radio frequency transmitting end and the radio frequency receiving end cannot perform normal communication any more due to different communication mechanisms, so that the radio frequency transceiver cannot be upgraded again and cannot be used again.

This phenomenon is common in unmanned aerial vehicles. The unmanned aerial vehicle comprises an aircraft and a remote controller for remotely controlling the aircraft. With the continuous progress of technology, unmanned aerial vehicles can perform system updating. In the upgrading process of the unmanned aerial vehicle, communication between the aircraft and the remote controller is required to be maintained at any time, so that the update of the aircraft and the update of the remote controller are realized. When certain emergency conditions occur during the upgrade process, such as when the aircraft is powered down and automatically shuts down, communication interruption can cause one of the aircraft and the remote control to upgrade successfully, while the other upgrade fails. When the aircraft is started again and is ready to be upgraded, different communication mechanisms are adopted due to different versions of the aircraft and the remote controller, normal radio frequency communication cannot be carried out between the aircraft and the remote controller, so that the aircraft cannot be upgraded, and the remote controller cannot be continuously used for remotely controlling the aircraft.

Detailed Description

The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.

Referring to fig. 1, an application scenario of a communication method and apparatus according to an embodiment of the present invention is shown. The embodiment of the invention can realize the communication between the radio frequency transmitting end and the radio frequency receiving end. Specifically, the rf transmitting end 110 includes an rf transceiver and a controller communicatively connected to the rf transceiver; the rf receiver 120 includes an rf transceiver and a controller communicatively coupled to the rf transceiver. The rf transceiver of the rf transmitting end 110 communicates with the rf transceiver of the rf receiving end 120 to complete the firmware upgrade.

In one implementation, the controller may be a single-chip microcomputer, that is, the rf transmitting end 110 and the rf receiving end 120 may both use a single-chip microcomputer, and the single-chip microcomputer drives the rf transceiver (or the rf transceiver device) to implement communication. In one implementation, the radio frequency transceiver may be a radio frequency transmitting chip and/or a radio frequency receiving chip, and the controller may drive the radio frequency transceiver to transmit and receive the pairing information. The rf transmitting end 110 may drive the rf transceiver to transmit the code broadcasting information through the built-in controller, and may also receive the code broadcasting information corresponding to the matched frequency, such as receiving the code confirmation information sent by the rf transceiver of the rf receiving end 120.

It should be noted that, the rf transceivers of the rf transmitting end and the rf receiving end may be rf communication devices having both functions of transmitting rf and receiving rf. The "rf transmitting end" and "rf receiving end" in the embodiments of the present invention are relative concepts, and are only used for descriptive purposes, and are not to be construed as limiting the rf transceiver of the end to have only rf transmitting functions or only rf receiving functions. In different implementations, the radio frequency transceiver used by the radio frequency transmitting end and the radio frequency transceiver used by the radio frequency receiving end may be the same or different.

More specifically, the rf receiver 120 may receive the code-matching broadcast information sent by the rf transmitter 110, obtain the version number of the rf transmitter 110 therein, and return code-matching confirmation information to the rf transmitter, where the code-matching confirmation information includes the version number of the rf receiver 120. After receiving the confirmation information, the rf transmitting end 110 determines its own communication mechanism according to its own version number and the version number of the rf receiving end 120. Similarly, the rf receiving end 120 determines its own communication mechanism according to its own version number and the received version number of the rf transmitting end 110. By adjusting the communication mechanism, the communication mechanisms of the rf transmitting end 110 and the rf receiving end 120 are kept consistent, so that the problem that the rf transmitting end and the rf receiving end cannot normally communicate or cannot normally use due to upgrade failure can be avoided.

As shown in fig. 2, a communication method according to an embodiment of the present invention is applicable to the application environment shown in fig. 1, and specifically includes the following steps:

step S202, the radio frequency transmitting end transmits code matching broadcast information, wherein the code matching broadcast information comprises a version number of the radio frequency transmitting end.

After entering a code matching state, the radio frequency transmitting end can transmit code matching broadcast information according to own code matching frequency, so that other devices which are in the broadcast range and are matched with the radio frequency transmitting end in frequency can receive the broadcast information. The radio frequency broadcast information contains a version number of the radio frequency transmitting end. The version number may be the version number of the operating system to be checked on the radio frequency transmitting end, or the version number of the application such as the driver of the firmware to be checked on the radio frequency transmitting end. The version number is a unique identifier of the corresponding application or system, and version information of the corresponding application or system can be obtained through the version number. The radio frequency transmitting end can automatically read the version number of the application or system which is updated last time, and load the version number into the code broadcasting information for broadcasting.

Step S204, receiving the code checking information returned by the radio frequency receiving terminal, wherein the code checking information comprises the version number of the radio frequency receiving terminal.

In this embodiment, when the radio frequency transmitting end and the radio frequency receiving end matched with the radio frequency transmitting end are within a preset communication range and the radio frequency receiving end also enters a code matching state, the radio frequency receiving end can receive the broadcast information with the fixed frequency transmitted by the radio frequency transmitting end and respond, and transmit code matching confirmation information to the radio frequency transmitting end according to the code matching frequency of the radio frequency receiving end, so that the radio frequency transmitting end and the radio frequency receiving end enter the code matching communication state. The pair of code confirmation information comprises a version number of the radio frequency receiving end. The version number is matched with the version number contained in the code-pair broadcasting information. For example, if the version number included in the pair of code broadcast information is the version number of the operating system of the radio frequency transmitting end, the version number of the radio frequency receiving end is the version number of the operating system of the radio frequency receiving end. If the version number contained in the pair of code broadcasting information is the version number of the application such as the drive of a certain firmware in the radio frequency transmitting end, the version number of the radio frequency receiving end is the version number of the corresponding application in the radio frequency receiving end controlled by the firmware.

The radio frequency transmitting end can receive the code checking confirmation information returned by the radio frequency receiving end and acquire the version number of the radio frequency receiving end carried by the code checking confirmation information.

Step S206, determining a communication mechanism of the radio frequency transmitting end according to the version number of the radio frequency transmitting end and the version number of the radio frequency receiving end, so that the radio frequency transmitting end performs radio frequency communication with the radio frequency receiving end according to the determined communication mechanism.

In this embodiment, the communication mechanism is a mechanism adopted by both the radio frequency transmitting end and the radio frequency receiving end for radio frequency communication. The communication mechanisms include multiple, different versions of the system or application, which by default do not necessarily use the same communication mechanism. When one end of the radio frequency transmitting end or the radio frequency receiving end is successfully upgraded and the other end is failed to be upgraded, the communication mechanisms of the radio frequency transmitting end and the radio frequency receiving end are different, so that normal communication cannot be performed.

After the radio frequency transmitting end reads the version number of the radio frequency transmitting end and the version number of the radio frequency receiving end, whether the communication mechanism used by the radio frequency transmitting end is simultaneously applicable to the systems or applications corresponding to the two version numbers can be detected. If yes, the current communication mechanism is not modified, and the radio frequency receiving end is enabled to modify the communication mechanism. If not, the current communication mechanism is modified into a communication mechanism which is simultaneously applicable to the systems or applications at two ends, and the communication is carried out with the radio frequency receiving end according to the modified communication mechanism, so that the problem that the radio frequency transceiver of the radio frequency transmitting end and the radio frequency receiving end cannot be normally used and the problem that the radio frequency transmitting end and the radio frequency receiving end cannot normally communicate can be avoided.

Specifically, the radio frequency transmitting end presets communication mechanisms applicable to different version numbers. When it is determined that updating is required, the radio frequency transmitting end can query a communication mechanism applicable to the version number of the radio frequency transmitting end and query a communication mechanism applicable to the version number of the radio frequency receiving end, select one of the communication mechanisms applicable to the two version numbers, switch the current communication mechanism of the radio frequency transmitting end to the selected communication mechanism, and send the selected communication mechanism to the radio frequency receiving end, so that the radio frequency receiving end adjusts the communication mechanism of the radio frequency receiving end. Further, the radio frequency transmitting end can also transmit the selected communication mechanism to the radio frequency receiving end, so that the radio frequency receiving end adjusts the communication mechanism of the radio frequency receiving end.

According to the communication method, when the radio frequency sending end and the radio frequency receiving end cannot normally communicate due to the failure of upgrading, the radio frequency sending end and the radio frequency receiving end enter a code matching communication state, the radio frequency sending end transmits code matching broadcast information and receives code matching confirmation information returned by the radio frequency receiving end, and a communication mechanism of the radio frequency sending end is determined according to the version number of the radio frequency sending end and the version number of the radio frequency receiving end contained in the code matching confirmation information, so that the radio frequency sending end and the radio frequency receiving end can carry out radio frequency communication according to the determined communication mechanism, the radio frequency sending end and the radio frequency receiving end can always keep the same communication mechanism, and normal communication can be carried out.

In one embodiment, step S206 further comprises: and determining the matched communication mechanism identification according to the version number of the radio frequency transmitting end and the version number of the radio frequency receiving end, and adjusting the communication mechanism of the radio frequency transmitting end into a communication mechanism corresponding to the communication mechanism identification.

The communication mechanism identifier is used for uniquely identifying one communication mechanism, and the radio frequency transmitting end establishes corresponding relations between different version numbers and the communication mechanism identifiers in advance, wherein the corresponding relations are used for representing that the corresponding communication mechanism is applicable to the application or the system of the corresponding version.

The radio frequency transmitting end can select a communication mechanism identifier with a corresponding relation with the two version numbers according to the version number of the radio frequency transmitting end and the version number of the radio frequency receiving end, and the communication mechanism identifier is the communication mechanism identifier matched with the two version numbers. The radio frequency transmitting end can determine the communication mechanism corresponding to the matched communication mechanism identifier as the communication mechanism of the radio frequency transmitting end, so that the radio frequency transmitting end can carry out radio frequency communication with the radio frequency receiving end according to the determined communication mechanism.

Specifically, the communication mechanism identifier of the mobile terminal can be set, and the response information of the code pair confirmation information is sent to the radio frequency receiving terminal, and the code pair state is ended. After the code matching state is finished, the communication mechanism of the communication device is adjusted according to the set communication mechanism identification.

In this embodiment, the communication mechanism of the radio frequency transmitting end is adjusted according to the version number, so that a communication mechanism applicable to both the radio frequency transmitting end and the radio frequency receiving end can be selected, and the two communication mechanisms can communicate according to the communication mechanism.

In one embodiment, the communication mechanism is: if the version number of the radio frequency transmitting end is higher than that of the radio frequency receiving end, the radio frequency transmitting end reverts the communication mechanism to the communication mechanism used by the last version number; if the version number of the radio frequency transmitting end is lower than that of the radio frequency receiving end or the version number of the radio frequency transmitting end is the same as that of the radio frequency receiving end, the radio frequency transmitting end does not update the communication mechanism.

In general, a high-version application or system may be compatible with the communication mechanism for which a corresponding low-version application or system is adapted. The default communication mechanism corresponding to the version number of the lower-version end can be selected and determined as the communication mechanism of the radio frequency transmitting end.

The radio frequency transmitting end can compare the two version numbers, and when the version numbers are inconsistent, one of the two version numbers fails to update. Specifically, if the version number of the radio frequency transmitting end is higher than the version number of the radio frequency receiving end, the version update of the radio frequency transmitting end is successful, and the version update of the radio frequency receiving end fails. The radio frequency transmitting end can trigger a corresponding radio frequency mechanism restoring instruction according to the comparison result, acquire an installation package of the radio frequency mechanism used last time according to the instruction to restore, and determine the restored radio frequency mechanism as a new radio frequency mechanism. If the version number of the radio frequency transmitting end is lower than that of the radio frequency receiving end or the version number of the radio frequency transmitting end is the same as that of the radio frequency receiving end, the communication mechanism of the radio frequency transmitting end does not need to be updated, and the radio frequency receiving end can update the radio frequency mechanism.

Specifically, a default communication mechanism identifier corresponding to the lower version number may be selected, and whether the communication mechanism identifier is applicable to a system or an application of a higher version is detected, if so, the corresponding communication mechanism is determined to be the communication mechanism of the radio frequency transmitting end. Therefore, the version number of one end of the radio frequency communication terminal is kept unchanged, and the speed of recovering radio frequency communication between the radio frequency transmitting terminal and the radio frequency receiving terminal is improved.

In this embodiment, the version number of the radio frequency transmitting end is compared with the version number of the radio frequency receiving end, and the radio frequency transmitting end with a low version number is updated in the communication mechanism so as to restore to the communication mechanism corresponding to the previous version. While for one end of the low version, the communication mechanism is kept unchanged; or when the version numbers at the two ends are the same, the passing mechanism is kept unchanged, so that unnecessary updating of the communication mechanism is avoided, and the speed of recovering normal communication between the radio frequency transmitting end and the radio frequency receiving end is improved.

As shown in fig. 3, a specific flowchart of steps for determining a communication mechanism of a radio frequency transmitting end according to an embodiment of the present invention is shown:

In step S401, the radio frequency transmitting end enters a code matching state.

In this embodiment, when detecting a touch operation corresponding to the code entering state, the radio frequency transmitting end enters the code entering state. Specifically, the radio frequency transmitting end can be provided with a button for entering code matching communication, and the code matching state is entered when the button is detected to be correspondingly operated such as long-pressed. Or the radio frequency transmitting end can also provide other triggering modes, and enter a code matching state according to the triggering modes.

Step S402, transmitting code-matching broadcast information, wherein the code-matching broadcast information comprises a version number of a radio frequency transmitting end.

Step S403, detecting whether the code checking confirmation information returned by the radio frequency receiving end is received, if yes, executing step S404, otherwise, continuing executing step S402.

In this embodiment, the radio frequency transmitting end may detect in real time whether the code matching confirmation information returned by the radio frequency receiving end is received, and if not, continuously transmit the code matching broadcast information according to the preset frequency. If the pair of code confirmation information is received, the following step S404 is performed.

Step S404, reading the version number of the radio frequency receiving end carried by the code checking information.

Step S405, corresponding communication mechanism identification is set according to the version number of the radio frequency transmitting end and the version number of the radio frequency receiving end.

Step S406, the code matching state is exited.

Before exiting the code matching state, the radio frequency transmitting end can send response information to the code matching confirmation information to the radio frequency receiving terminal after the communication mechanism identifier is set so as to inform the radio frequency receiving end, and then, the radio frequency transmitting end exits the code matching state.

Step S407, determining a corresponding communication mechanism of the radio frequency transmitting end according to the set communication mechanism identification.

According to the communication method, the radio frequency transmitting end obtains the version number of the radio frequency receiving end in the code matching state, sets the corresponding communication mechanism identification according to the version number, can determine the corresponding communication mechanism according to the set communication mechanism identification after exiting the code matching state, and communicates with the radio frequency receiving end according to the determined communication mechanism of the radio frequency transmitting end, so that the problem that the radio frequency transceiver of the radio frequency transmitting end and the radio frequency receiving end cannot be normally used and the problem that the radio frequency transmitting end and the radio frequency receiving end cannot normally communicate can be avoided.

In an embodiment, the radio frequency transmitting end may be an aircraft and/or a remote controller of the unmanned aerial vehicle, and the radio frequency receiving end may be a remote controller and/or an aircraft of the unmanned aerial vehicle. For example, in one implementation, the rf transmitting end is a remote control of an unmanned aerial vehicle, and the rf receiving end is an aircraft matching with the remote control. In another implementation mode, the radio frequency transmitting end is an unmanned aerial vehicle, and the radio frequency receiving end is a remote controller matched with the unmanned aerial vehicle.

By adjusting the communication mechanism, the remote controller or the aircraft serving as the radio frequency transmitting end and the communication mechanism of the aircraft or the remote controller serving as the radio frequency receiving end are kept consistent, and the problem that the remote controller and the aircraft cannot normally communicate or cannot normally use due to different versions caused by upgrading failure can be avoided.

As shown in fig. 4, a communication method according to another embodiment of the present invention is applicable to the application environment shown in fig. 1, and specifically includes the following steps:

in step S302, the radio frequency receiving end receives the code matching broadcast information transmitted by the radio frequency transmitting end, where the code matching broadcast information includes the version number of the radio frequency transmitting end.

After receiving the code matching broadcast information transmitted by the radio frequency transmitting end, the radio frequency receiving end and the radio frequency transmitting end successfully establish code matching communication, and can receive the code matching broadcast information transmitted by the radio frequency transmitting end and read the version number of the radio frequency transmitting end contained in the code matching broadcast information.

Step S304, the version number of the radio frequency receiving end is read, code checking confirmation information is transmitted to the radio frequency transmitting end, and the code checking confirmation information comprises the version number of the radio frequency receiving end, so that the radio frequency transmitting end determines whether to update the communication mechanism of the radio frequency transmitting end.

In this embodiment, the radio frequency receiving end may further read the version number of the application or system corresponding to the version number of the radio frequency transmitting end installed by itself. Meanwhile, the read version number can be written into the code matching confirmation information and the code matching confirmation information is sent to the radio frequency sending end, so that the radio frequency sending end can determine that the code matching communication is realized according to the code matching confirmation information and determine whether the communication mechanism of the radio frequency sending end needs to be updated according to the version number carried in the code matching confirmation information.

Step S306, determining a communication mechanism of the radio frequency receiving end according to the version number of the radio frequency transmitting end and the version number of the radio frequency receiving end, so that the radio frequency receiving end performs radio frequency communication with the radio frequency transmitting end according to the determined communication mechanism.

In this embodiment, similar to the rf transmitting end, the rf receiving end also determines whether to update its own communication mechanism according to its own version number and the version number of the rf transmitting end.

After the radio frequency receiving end reads the version number of the radio frequency receiving end and the version number of the radio frequency transmitting end, whether the communication mechanism used by the radio frequency receiving end is simultaneously applicable to the systems or applications corresponding to the two version numbers can be detected. If yes, the current communication mechanism is not modified, and the radio frequency transmitting end is enabled to modify the communication mechanism. If not, the current communication mechanism is modified into a communication mechanism which is simultaneously applicable to the systems or applications at two ends, and the communication is carried out with the radio frequency sending end according to the modified communication mechanism, so that the problem that the radio frequency transceivers of the radio frequency sending end and the radio frequency receiving end cannot be normally used and the problem that the radio frequency sending end and the radio frequency receiving end cannot normally communicate can be avoided.

Specifically, the radio frequency receiving end presets communication mechanisms applicable to different version numbers. When it is determined that the update is required, the radio frequency receiving end may also query a communication mechanism applicable to the version number of the radio frequency transmitting end and query a communication mechanism applicable to the version number of the radio frequency receiving end, select one of the communication mechanisms applicable to the two version numbers, switch the current communication mechanism of the radio frequency transmitting end to the selected communication mechanism, and send the selected communication mechanism to the radio frequency receiving end, so that the radio frequency receiving end adjusts its own communication mechanism. Further, the radio frequency transmitting end can also transmit the selected communication mechanism to the radio frequency receiving end, so that the radio frequency receiving end adjusts the communication mechanism of the radio frequency receiving end.

The communication method can enable the two parties to enter a code matching communication state when the radio frequency transmitting end and the radio frequency receiving end cannot normally communicate due to the failure of upgrading. The radio frequency receiving terminal receives code matching broadcast information transmitted by the radio frequency transmitting terminal, wherein the code matching broadcast information comprises the version number of the radio frequency transmitting terminal; reading the version number of the radio frequency receiving end, transmitting code checking confirmation information to the radio frequency transmitting end, wherein the code checking confirmation information comprises the version number of the radio frequency receiving end, so that the radio frequency transmitting end determines whether to update the communication mechanism of the radio frequency transmitting end; and determining whether to update the communication mechanism of the radio frequency receiving end according to the version number of the radio frequency transmitting end and the version number of the radio frequency receiving end so that the radio frequency transmitting end and the radio frequency receiving end always keep the same communication mechanism, and normal communication can be performed.

In one embodiment, step S306 further comprises: and determining the matched communication mechanism identification according to the version number of the radio frequency transmitting end and the version number of the radio frequency receiving end, and adjusting the communication mechanism of the radio frequency receiving end into a communication mechanism corresponding to the communication mechanism identification.

In this embodiment, the radio frequency receiving end also presets a communication mechanism applicable to different version numbers. The radio frequency receiving end can select a communication mechanism identifier with a corresponding relation with the two version numbers according to the version number of the radio frequency receiving end and the version number of the radio frequency receiving end, and the communication mechanism identifier is the communication mechanism identifier matched with the two version numbers. The radio frequency receiving end can determine the communication mechanism corresponding to the matched communication mechanism identifier as the communication mechanism of the radio frequency receiving end, so that the radio frequency receiving end can carry out radio frequency communication with the radio frequency sending end according to the determined communication mechanism.

Specifically, the set communication mechanism identifier may also be included in the response information, or the pair code information may be sent to the radio frequency sending end again, where the pair code information includes the set communication mechanism identifier. And finishing the code matching state, and adjusting the communication mechanism according to the set communication mechanism identifier after finishing the code matching state.

In one embodiment, the communication mechanism is: if the version number of the radio frequency transmitting end is lower than that of the radio frequency receiving end, the radio frequency receiving end reverts the communication mechanism to the communication mechanism used by the last version number; if the version number of the radio frequency transmitting end is higher than that of the radio frequency receiving end or the version number of the radio frequency transmitting end is the same as that of the radio frequency receiving end, the radio frequency transmitting end does not update the communication mechanism.

The radio frequency receiving end can compare the two version numbers, and when the version numbers are inconsistent, one of the two version numbers fails to update. Specifically, if the version number of the radio frequency receiving end is higher than the version number of the radio frequency transmitting end, the version number of the radio frequency receiving end is successfully updated, and the version number of the radio frequency transmitting end fails to be updated. The radio frequency receiving end can trigger a corresponding communication mechanism restoration instruction according to the comparison result, acquire an installation package of the radio frequency mechanism used last time according to the instruction to restore, and determine the restored radio frequency mechanism as a new radio frequency mechanism. If the version number of the radio frequency transmitting end is higher than that of the radio frequency receiving end or the version number of the radio frequency transmitting end is the same as that of the radio frequency receiving end, the communication mechanism of the radio frequency receiving end does not need to be updated, and the radio frequency transmitting end can update the radio frequency mechanism.

Or the radio frequency transmitting end can also provide other triggering modes, and enter a code matching state according to the triggering modes. And receiving the code matching information broadcasted by other terminals at the matched frequency, wherein the code matching information comprises code matching broadcasting information sent by the radio frequency sending terminal.

Step S502, detecting whether the code broadcasting information transmitted by the radio frequency transmitting end is received, if yes, executing step S503, otherwise, repeatedly executing step S502.

The radio frequency receiving end can continuously detect whether the code broadcasting information transmitted by the radio frequency transmitting end is received or not.

In step S503, the version number of the radio frequency transmitting end is read from the code matching broadcast information.

Step S504, corresponding communication mechanism identification is set according to the version number of the radio frequency transmitting end and the version number of the radio frequency receiving end.

In step S505, the code matching state is exited.

Further, before exiting the code matching state, the radio frequency receiving end can send a code matching message carrying the set communication mechanism identifier to the radio frequency sending terminal after the communication mechanism identifier is set, so as to inform the radio frequency sending end.

Step S506, corresponding communication mechanism of the radio frequency receiving end is determined according to the set communication mechanism identification.

According to the communication method, the radio frequency receiving end obtains the version number of the radio frequency transmitting end in the code matching state, sets the corresponding communication mechanism identification according to the version number, can determine the corresponding communication mechanism according to the set communication mechanism identification after exiting the code matching state, and communicates with the radio frequency transmitting end according to the determined communication mechanism of the radio frequency receiving end, so that the problem that the radio frequency transmitting end and the radio frequency transceiver of the radio frequency receiving end cannot be normally used and the problem that the radio frequency transmitting end and the radio frequency receiving end cannot normally communicate can be avoided.
