Technical field

The present invention relates to the field of communications technologies, and in particular, to a communication method, apparatus, and drone.

Background technique

In the field of communications, firmware upgrades are based on radio frequency communication between radio frequency transceivers (radio frequency transmitting devices, radio frequency receiving devices), in accordance with a certain communication mechanism. Different versions of RF transceivers use different communication mechanisms. During the firmware upgrade process, if the upgrade is aborted for some reason, the phenomenon may occur that one end of the RF sender and the RF receiver is successfully upgraded, and the other end fails to be upgraded. The new communication mechanism is used, and the one that has not been successfully upgraded still uses the old communication mechanism. In this case, when the RF transceiver is restarted and the upgrade is to be completed, since the RF transmitter and the RF receiver use different communication mechanisms, normal communication cannot be performed, and thus the upgrade cannot be performed again. Use again.

This phenomenon is common in drones. The drone includes an aircraft and a remote control that remotely controls the aircraft. As technology continues to advance, drones can be updated. During the upgrade process, the drone needs to maintain communication between the aircraft and the remote controller at any time to update the aircraft and update the remote controller. When some unexpected situations occur during the upgrade process, such as when the aircraft is exhausted and the power is automatically turned off, the communication is interrupted, which will cause the aircraft and the remote controller to upgrade successfully, and the other party fails to upgrade. When the aircraft is turned on again and ready to be upgraded, different communication mechanisms are used due to different versions of the aircraft and the remote controller, and normal RF communication will not be possible between them, so the upgrade cannot be performed and the remote control cannot be used. To remotely control the aircraft.

Detailed ways

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit 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 solution of the embodiment of the invention can implement communication between the radio frequency transmitting end and the radio frequency receiving end. In particular, radio frequency transmitting end 110 includes a radio frequency transceiver and a controller in communication with the radio frequency transceiver; radio frequency receiving end 120 includes a radio frequency transceiver and a controller in communication with the radio frequency transceiver. The radio frequency transceiver of the radio frequency transmitting end 110 communicates with the radio frequency transceiver of the radio frequency 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 each adopt a single chip microcomputer, and the single chip drives the RF transceiver (or the RF transceiver device) to implement communication. In an implementation manner, 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 send and receive the code information. The radio frequency transmitting end 110 can transmit the code broadcast information through the built-in controller to drive the radio frequency transceiver, and can also receive the code information corresponding to the matched frequency, such as the code confirmation information sent by the radio frequency transceiver receiving the radio frequency receiving end 120.

It should be noted that the radio frequency transceivers of the radio frequency transmitting end and the radio frequency receiving end may both be radio frequency communication devices that simultaneously transmit radio frequency and receive radio frequency functions. The "radio frequency transmitting end" and the "radio frequency receiving end" in the embodiments of the present invention are relative concepts, and are only used for description purposes, and cannot be understood as the radio frequency transceiver that defines the end only has a radio frequency transmitting function or only has a radio frequency receiving function. . In different implementation manners, 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 radio frequency receiving end 120 can receive the code broadcast information sent by the radio frequency transmitting end 110, obtain the version number of the radio frequency transmitting end 110, and return the code confirmation information to the radio frequency transmitting end, where the pair of code confirmation information is The version number of the radio frequency receiving end 120 is included. After receiving the confirmation information, the RF transmitting end 110 determines its own communication mechanism according to its version number and the version number of the RF receiving end 120. Similarly, the radio frequency receiving end 120 also determines its own communication mechanism according to its own version number and the version number of the received radio frequency transmitting end 110. By adjusting the communication mechanism, the communication mechanisms of the RF transmitting end 110 and the RF receiving end 120 are consistent, which avoids the problem that the RF transmitting end and the RF receiving end cannot communicate normally or cannot be used normally due to the upgrade failure.

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

Step S202: The radio frequency transmitting end transmits the code broadcast information, where the code broadcast information includes the version number of the radio frequency transmitting end.

First, the controller of the RF transmitting end controls the RF transmitting end to enter the code matching state. After entering the code matching state, the RF transmitting end may transmit the code broadcast information according to its own code frequency, so that other devices in the broadcast range that match the frequency can receive the broadcast information. The radio broadcast information includes the version number of the radio transmitter. The version number may be the version number of the operating system to be verified on the radio frequency transmitting end, or the version number of the application such as the driver of the firmware to be verified on the radio frequency transmitting end. The version number is a unique identifier of the corresponding application or system. The version number can be used to obtain the version information of the corresponding application or system. The RF sender can automatically read the version number of the application or system that was last updated, and load the version number into the code broadcast information for broadcast.

Step S204, receiving the code confirmation information returned by the radio frequency receiving end, where the code confirmation information includes the version number of the radio frequency receiving end.

In this embodiment, when the radio frequency transmitting end and the matched radio frequency receiving end are in a preset communication range, and the radio frequency receiving end also enters the code matching state, the radio frequency receiving end can receive the radio frequency transmitting end. The broadcast information of the fixed frequency is sent and responds, and the code confirmation message is sent to the radio frequency transmitting end according to its own code frequency, so that the two enter the code communication state. The pair of code confirmation information includes a version number of the radio frequency receiving end. The version number matches the version number included in the code broadcast information. For example, if the version number included in the 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 included in the code broadcast information is a version number of an application such as a driver of a firmware in the radio frequency transmitting end, the version number of the radio frequency receiving end is a radio frequency receiving end, and the firmware is controlled or controlled by the firmware. The version number of the corresponding application.

The radio frequency transmitting end can receive the code confirmation information returned by the radio frequency receiving end, and obtain the version number of the radio frequency receiving end carried therein. Step S206: Determine 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 used for radio frequency communication between the radio frequency transmitting end and the radio frequency receiving end. Communication mechanisms include multiple, different versions of systems or applications, and the communication mechanisms used by default are not necessarily the same. When one end of the RF transmitter or the RF receiver is successfully upgraded and the other end fails to be upgraded, the communication mechanism of the two will be different and communication will not be possible.

After reading the version number of the radio and the version number of the radio receiving end, the radio transmitting end can detect whether the communication mechanism used by the radio transmitting end is applicable to the system or application corresponding to the two version numbers. If yes, the current communication mechanism is not modified, and the radio frequency receiving end is modified by the communication mechanism. If not, the current communication mechanism is modified to be applicable to the communication mechanism of the system or application at both ends, and communicates with the RF receiving end according to the modified communication mechanism, thereby avoiding the failure to properly use the RF transceiver of the RF transmitting end and the RF receiving end. The problem is that the RF sender and the RF receiver cannot communicate properly.

Specifically, the radio frequency transmitting end presets a communication mechanism to which different version numbers are applied. When it is determined that the update needs to be performed, the radio transmitting end can query the communication mechanism applicable to the version number of the radio frequency transmitting end, and query the communication mechanism applicable to the version number of the radio receiving end, and select one of the communications applicable to the two version numbers. The mechanism switches the current communication mechanism of the radio frequency transmitting end to the selected communication mechanism, and sends 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 may also send the selected communication mechanism to the radio frequency receiving end, so that the radio frequency receiving end adjusts its own communication mechanism.

The above communication method can enable both parties to enter the code communication state when the upgrade occurs, causing the radio frequency transmitting end and the radio frequency receiving end to fail to perform normal communication, and the radio frequency transmitting end transmits the pair code broadcast information and receives the return of the radio frequency receiving end. For the code confirmation information, the communication mechanism of the radio frequency transmitting end is determined according to the version number of the radio frequency transmitting end itself and the version number of the radio frequency receiving end included in the code confirmation information, so that the radio frequency transmitting end according to the determined communication mechanism and the radio frequency receiving end The radio frequency communication is performed so that the radio frequency transmitting end and the radio frequency receiving end always maintain a consistent communication mechanism, so that normal communication can be performed for normal communication.

In an embodiment, step S206 further includes: determining a matching communication mechanism identifier according to a version number of the radio frequency transmitting end and a version number of the radio frequency receiving end, and adjusting a communication mechanism of the radio frequency transmitting end to a communication mechanism corresponding to the communication mechanism identifier.

The communication mechanism identifier is used to uniquely identify a communication mechanism. The radio frequency sender pre-establishes a correspondence between different version numbers and a communication mechanism identifier, and the correspondence relationship is used to indicate that the corresponding communication mechanism is applicable to the corresponding version of the application or system.

The radio transmitter may select a communication mechanism identifier corresponding to the two version numbers according to the version number of the radio and the version number of the radio receiver, and the communication mechanism identifier is a communication mechanism that matches the two version numbers. Logo. 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 it performs radio frequency communication with the radio frequency receiving end according to the determined communication mechanism.

Specifically, the communication mechanism identifier of the self can be set, and the response information of the pair of code confirmation information is sent to the radio frequency receiving end, and the code status is ended. After the code status is ended, its communication mechanism is adjusted according to the set communication mechanism identifier.

In this embodiment, by adjusting the communication mechanism of the radio frequency transmitting end according to the version number, a communication mechanism suitable for both the radio frequency transmitting end and the radio frequency receiving end can be selected, so that the two communicate according to the communication mechanism.

In an embodiment, the communication mechanism of the radio frequency transmitting end is determined according to the version number of the radio frequency transmitting end and the version number of the radio frequency receiving end, which is specifically: comparing a version number of the radio frequency transmitting end with a version number of the radio frequency receiving end If the version number of the RF transmitting end is higher than the version number of the RF receiving end, the RF transmitting end restores the communication mechanism to the communication mechanism used by the previous version number; if the version number of the RF transmitting end is lower than the version number of the RF receiving end, or If the version number of the RF receiver is the same, the RF sender does not update the communication mechanism.

In general, a higher version of an application or system is compatible with the communication mechanisms that are appropriate for the lower version of the application or system. The default communication mechanism corresponding to the version number of the lower version of the version can be selected as the communication mechanism of the RF sender.

The RF sender can compare the two version numbers. When the version numbers are inconsistent, it indicates that one of the updates failed. Specifically, if the version number of the radio transmitter is higher than the version number of the radio receiver, the version of the radio transmitter is updated successfully, and the version update of the radio receiver fails. The radio frequency transmitting end may trigger a corresponding radio frequency mechanism restoration instruction according to the comparison result, obtain an installation package of the last used radio frequency mechanism according to the instruction, and restore the restored radio frequency mechanism as a new radio frequency mechanism. If the version number of the radio transmitter is lower than the version number of the radio receiver, or the version number of the radio receiver is the same, the communication mechanism of the radio transmitter does not need to be updated, so that the radio receiver can update the radio frequency mechanism.

Specifically, the default communication mechanism identifier corresponding to the lower version number may be selected to detect whether the communication mechanism identifier is also applicable to a higher version system or application, and if yes, determine the corresponding communication mechanism as the radio frequency sender communication. mechanism. Therefore, the version number of one end can be kept unchanged, and the speed of restoring radio frequency communication between the radio frequency transmitting end and the radio frequency receiving end is improved.

In this embodiment, by comparing the version number of the radio frequency transmitting end with the version number of the radio frequency receiving end, the radio frequency transmitting end with the lower version number is updated with the communication mechanism to restore the communication mechanism corresponding to the previous version. For the lower version, the communication mechanism is kept unchanged; or, when the version numbers of the two versions are the same, the traffic mechanism is kept unchanged, thereby avoiding unnecessary updating of the communication mechanism, and improving the RF transmitting end and the RF receiving. The speed of normal communication between the ends is restored.

As shown in FIG. 3, it is a specific flowchart of the steps of determining a communication mechanism of a radio frequency transmitting end provided in an embodiment of the present invention:

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

In this embodiment, when the radio frequency transmitting end detects the corresponding touch operation with the entering code status, the radio frequency transmitting end enters the code matching state. Specifically, the button for entering the code communication can be provided on the radio frequency transmitting end, and when the corresponding operation of pressing the button for a long press is detected, the pair code state is entered. Alternatively, the radio transmitter can also provide other trigger modes, and enter the code status according to the trigger mode.

Step S402, transmitting code-to-code broadcast information, where the code broadcast information includes a version number of the radio frequency transmitting end.

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

In this embodiment, the radio frequency transmitting end can detect whether the code confirmation information returned by the radio frequency receiving end is received in real time, and if not, the code broadcast information is continuously transmitted 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 in the code confirmation information.

Step S405, setting a corresponding communication mechanism identifier according to the version number of the radio frequency transmitting end and the version number of the radio frequency receiving end.

In step S406, the code status is exited.

Before exiting the code status, the radio frequency transmitting end may send a response message to the radio frequency receiving terminal to the radio frequency receiving terminal after the communication mechanism identifier is set, to inform the radio frequency receiving end, and then exit the code status.

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

In the above communication method, the radio frequency transmitting end obtains the version number of the radio frequency receiving end in the code matching state, and sets the corresponding communication mechanism identifier according to the version number. After exiting the code matching state, the radio frequency transmitting end may determine the corresponding corresponding according to the set communication mechanism identifier. The communication mechanism communicates with the radio frequency receiving end according to the determined communication mechanism of the radio frequency transmitting end, which can avoid the problem that the radio frequency transceiver of the radio frequency transmitting end and the radio frequency receiving end cannot be used normally, and the radio transmitting end and the radio receiving end cannot communicate normally. .

In one embodiment, the radio frequency transmitting end may be an aircraft and/or a remote controller of the drone, and the radio frequency receiving end may be a remote controller and/or an aircraft of the drone. For example, in one implementation, the radio frequency transmitting end is a remote controller of the drone, and the radio frequency receiving end is an aircraft matched with the remote controller. In another implementation, the RF transmitting end is an aircraft of the drone, and the RF receiving end is a remote controller matched with the aircraft.

By adjusting the communication mechanism, the communication mechanism of the remote controller or the aircraft as the RF transmitting end is consistent with the communication mechanism of the aircraft or the remote controller as the RF receiving end, so that the version between the remote controller and the aircraft due to the upgrade failure can be prevented from being different. A problem that communicates normally or is not working properly.

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

Step S302: The radio frequency receiving end receives the code broadcast information transmitted by the radio frequency transmitting end, where the code broadcast information includes the version number of the radio frequency transmitting end.

First, the controller at the RF receiving end controls the RF receiving end to enter the code matching state. After receiving the code broadcast information transmitted by the radio frequency transmitting end, the radio frequency receiving end and the radio frequency transmitting end successfully establish a pair code communication, and can receive the code broadcast information transmitted by the radio frequency transmitting end, and read the pair code broadcast information. The version number of the included RF sender.

Step S304: The version number of the radio frequency receiving end is read, and the code confirmation information is transmitted to the radio frequency transmitting end. The code confirmation information includes 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. At the same time, the version number of the read version can be written into the code confirmation information, and the pair of code confirmation information is sent to the radio frequency transmitting end, so that the radio frequency transmitting end can confirm that the two are implemented according to the pair of code confirmation information. For code communication, and according to the version number carried therein, it is determined whether the communication mechanism of the radio frequency transmitting end needs to be updated.

It can be understood that, in other embodiments, the transmitting the code confirmation information to the radio frequency transmitting end, where the code confirmation information includes 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. It may be performed after step S306, that is, step S304 may simply read the version number of the radio frequency receiving end.

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 radio frequency transmitting end, the radio frequency receiving end determines whether to update its own communication mechanism according to its version number and the version number of the radio frequency transmitting end.

After reading the version number of the radio and the version number of the radio transmitter, the radio receiving end can detect whether the communication mechanism currently used by itself is applicable to the system or application corresponding to the two version numbers. If yes, the current communication mechanism is not modified, and the radio frequency transmitting end is modified by the communication mechanism. If not, the current communication mechanism is modified to be applicable to the communication mechanism of the system or application at both ends, and the communication mechanism is communicated with the RF transmitting end according to the modified communication mechanism, so as to avoid the radio transceiver that cannot use the RF transmitting end and the RF receiving end normally. The problem is that the RF sender and the RF receiver cannot communicate properly.

Specifically, the radio frequency receiving end presets a communication mechanism to which different version numbers are applied. When it is determined that the update needs to be performed, the radio frequency receiving end may also query the communication mechanism applicable to the version number of the radio frequency transmitting end, and query the communication mechanism applicable to the version number of the radio frequency receiving end, and select one of them to be applicable to the two version numbers. The communication mechanism switches the current communication mechanism of the radio frequency transmitting end to the selected communication mechanism, and sends 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 may also send the selected communication mechanism to the radio frequency receiving end, so that the radio frequency receiving end adjusts its own communication mechanism.

The above communication method can make both parties enter the code communication state when the upgrade fails and the radio frequency transmitting end and the radio frequency receiving end cannot perform normal communication. The radio frequency receiving end receives the code broadcast information transmitted by the radio frequency transmitting end, and the code broadcast information includes the version number of the radio frequency transmitting end; the version number of the radio frequency receiving end is read, and the code confirmation information is transmitted to the radio frequency transmitting end, where the code confirmation information is included The version number of the radio receiving end, so that the radio frequency transmitting end determines whether to update the 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, determine whether to update the communication mechanism of the radio frequency receiving end, so that the radio frequency transmitting end The communication mechanism is always consistent with the RF receiving end, so that normal communication can be performed.

In an embodiment, step S306 further includes: determining a matching communication mechanism identifier according to a version number of the radio frequency transmitting end and a version number of the radio frequency receiving end, and adjusting a communication mechanism of the radio frequency receiving end to a communication mechanism corresponding to the communication mechanism identifier.

In this embodiment, the radio frequency receiving end also presets a communication mechanism to which different version numbers are applied. The radio receiving end may select a communication mechanism identifier corresponding to the two version numbers according to the version number of the radio frequency and the version number of the radio receiving end, and the communication mechanism identifier is a communication mechanism that matches both version numbers.
