For convenience of understanding, a specific flow of an embodiment of the present invention is described below, and referring to fig. 1, an embodiment of a wireless communication method between an unmanned aerial vehicle and a carrier box according to an embodiment of the present invention includes:
101. when the distance between unmanned aerial vehicle and the thing case satisfies the preset condition, establish wireless connection through first wireless communication module and the second wireless communication module in the thing case, obtain the connection result.
The preset condition is used for indicating a maximum communication range between the unmanned aerial vehicle and the carrying box, for example, the preset condition is greater than or equal to 0 cm and less than or equal to 10 cm, and if the distance between the unmanned aerial vehicle and the carrying box is 30 cm, the unmanned aerial vehicle determines that the distance between the unmanned aerial vehicle and the carrying box does not meet the preset condition; if the distance between the unmanned aerial vehicle and the carrying box is 10 centimeters or 5 centimeters, the unmanned aerial vehicle determines that the distance between the unmanned aerial vehicle and the carrying box meets the preset condition, namely, the unmanned aerial vehicle determines that the position of the carrying box is in the maximum communication range.
Specifically, when the distance between the unmanned aerial vehicle and the carrier box meets the preset condition, that is, when the distance between the first wireless communication module and the second wireless communication module in the carrier box is within the effective communication distance range, the unmanned aerial vehicle transmits preset wireless connection information between the first wireless communication module and the second wireless communication module in the carrier box through a preset wireless communication protocol, and establishes wireless connection between the first wireless communication module and the second wireless communication module in the carrier box according to the preset wireless connection information, so as to obtain a connection result. Wherein, first wireless communication module sets up in unmanned aerial vehicle's the main control panel that predetermines, and second wireless communication module sets up in the control panel of predetermineeing of year thing case.
It should be noted that the preset wireless communication protocol may adopt a preset near field communication protocol or a bluetooth communication protocol, and may also adopt a WI-FI communication protocol, which is not limited herein. Unmanned aerial vehicle can set up the corresponding preset condition according to presetting wireless communication agreement, and the preset condition can set up according to the practical application scene, specifically does not do the restriction here. The near field communication protocol, the Bluetooth communication protocol and the WI-FI communication protocol are respectively provided with corresponding preset conditions, so that the unmanned aerial vehicle can select the preset conditions according to an actual application scene, wireless connection is established according to the preset conditions corresponding to each wireless communication protocol, the preset conditions corresponding to each preset wireless communication protocol can be overlapped, and overlapping can be avoided. For example, for the near field communication protocol, the drone sets the corresponding preset condition to be greater than or equal to 0 and less than or equal to 4 centimeters; for the bluetooth communication protocol, the unmanned aerial vehicle may set the preset condition to be greater than 4 centimeters and less than or equal to 150 centimeters, or the unmanned aerial vehicle may also set the preset condition to be greater than 4 centimeters and less than or equal to 200 centimeters, which is not limited herein.
It can be understood that the execution subject of the present invention may be a wireless communication device of the drone and the carrier box, and may also be the drone or the carrier box, which is not limited herein. The embodiment of the invention takes an unmanned aerial vehicle as an execution main body for explanation.
102. And judging whether the connection result is connection failure or not.
The connection result comprises connection success and connection failure, and specifically, the unmanned aerial vehicle judges whether the connection result is a preset value or not; when the connection result is not the preset value, the unmanned aerial vehicle determines that the connection result is a connection failure, and continues to execute step 103, for example, the second wireless communication module is powered off, the communication network is abnormal, or the current position information of the second wireless module is changed, and the unmanned aerial vehicle does not scan the second wireless communication module within the preset time; and when the connection result is the preset value, the unmanned aerial vehicle determines that the connection result is successful, and continues to execute the step 104. For example, the drone may use 1 (i.e., a preset value) to indicate that the connection is successful, and may use 0 to indicate that the connection is failed, which is not limited herein.
103. And if the connection result is connection failure, reconnecting the first wireless communication module and the second wireless communication module according to the preset retry number, and stopping connection until the preset retry number is reached or the reconnection is successful.
That is, if the connection result is that the connection fails, and the first wireless communication module and the second wireless communication module both adopt the near field communication protocol for wireless communication, the unmanned aerial vehicle reestablishes wireless connection between the first wireless communication module and the second wireless communication module in the carrier box according to the near field communication protocol to obtain a reconnection result; if the connection result is that the connection fails and the first wireless communication module and the second wireless communication module adopt a Bluetooth communication protocol for wireless communication, the unmanned aerial vehicle reestablishes wireless connection between the first wireless communication module and the second wireless communication module in the object box according to the Bluetooth communication protocol to obtain a reconnection result; when the reconnection result is that the connection fails, the unmanned aerial vehicle reconnects the first wireless communication module and the second wireless communication module within the preset retry number according to the mode; when the reconnection result is that the connection is successful or the preset retry number is reached, the unmanned aerial vehicle stops connecting.
Further, after the unmanned aerial vehicle detects that the connection between the first wireless communication module and the second wireless communication module fails for N times, the unmanned aerial vehicle controls to close the first wireless communication module. Wherein N is an integer greater than zero and less than or equal to the preset retry number.
It should be noted that Near Field Communication (NFC) is developed by combining a wireless interconnection technology on the basis of a non-contact radio frequency identification RFID technology, and an unmanned aerial vehicle and a carrier box using the NFC technology can exchange data when they are close to each other.
104. If the connection result is that the connection is successful, data exchange processing is carried out through the first wireless communication module and the second wireless communication module, and the carrying box is controlled to be opened and closed.
Specifically, if the connection result is that the connection is successful, the unmanned aerial vehicle acquires a target communication channel established by the connection between the first wireless communication module and the second wireless communication module (the target communication channel is pre-established by adopting near field communication connection or bluetooth communication connection), and the unmanned aerial vehicle sends a data exchange request to the second wireless communication module through the target communication channel, so that the second wireless communication module receives the data exchange request and performs data operation according to the data exchange request to obtain an exchange result; and the unmanned aerial vehicle receives the exchange result sent by the second wireless communication module through the target communication channel. Further, unmanned aerial vehicle can also send year thing case on-off control instruction to second wireless communication module through target communication channel to make second wireless communication module carry out the on-off processing to carrying the thing case according to carrying thing case on-off control instruction.
In the embodiment of the invention, the unmanned aerial vehicle is wirelessly connected with the second wireless communication module in the carrying box through the first wireless communication module, so that the carrying box can be more conveniently replaced and detached, the on-off control of the carrying box is realized, the carrying box replacing efficiency is improved, and the express delivery distribution efficiency is improved.
Referring to fig. 2, another embodiment of the wireless communication method between the unmanned aerial vehicle and the carrier box according to the embodiment of the present invention includes:
201. the first wireless communication module is set as a master module, the second wireless communication module in the carrier box is set as a slave module, the master module is a master near field communication module or a master Bluetooth module, and the slave module is a slave near field communication module or a slave Bluetooth module.
The master module and the slave modules are in wireless connection by adopting the same wireless communication protocol, the master module and the slave modules are in one-to-one correspondence, when the master module is a master near field communication module, the slave modules are slave near field communication modules, and when the master module is a master Bluetooth module, the slave modules are slave Bluetooth modules.
Further, when the carrier case is mounted on the carrier rack of the drone, the drone starts and initializes the master near field communication module or the master bluetooth module (i.e., the first wireless communication module); the carrier starts and initializes the slave near field communication module or the slave bluetooth module (i.e., the second wireless communication module). Unmanned aerial vehicle sets up first wireless communication module into the slave module, and unmanned aerial vehicle sets up the second wireless communication module in with the thing case into the master module, and the master module is main near field communication module or main bluetooth module, and the slave module is for following near field communication module or from bluetooth module. That is, any one of the first wireless communication module of the unmanned aerial vehicle and the second wireless communication module of the carrier box may be a master module, another wireless communication module may be a slave module, and the master-slave state between the first wireless communication module and the second wireless communication module may also be switched according to the actual application scenario.
It should be noted that, in order to reduce the wireless communication cost and reduce the wiring space, when the actual application scenario is near field communication connection, the first wireless communication module and the second wireless communication module are respectively a master near field communication module and a slave near field communication module, and the unmanned aerial vehicle executes step 202; when the actual application scene is bluetooth communication connection, the first wireless communication module and the second wireless communication module are respectively a master bluetooth module and a slave bluetooth module, and the unmanned aerial vehicle executes step 203.
202. When the distance between the unmanned aerial vehicle and the carrying box meets the preset condition and is in near field communication connection, point-to-point connection is carried out through the master near field communication module and the slave near field communication module within the preset time length, and a connection result is obtained.
It should be noted that, compared to bluetooth, nfc has high security, and both have different preset conditions. That is, the preset condition may be set according to the type of the transmission protocol, for example, the preset condition for the drone to perform near field communication may be set to be greater than or equal to 0 and less than or equal to 10 centimeters (0.1 meter), and may also be set to be greater than or equal to 0 and less than or equal to 4 centimeters, and preferably, the distance between the drone and the carrier box is 4 centimeters, which is not limited herein.
Specifically, when the distance between the unmanned aerial vehicle and the carrying box meets the preset condition and is in near field communication connection, the unmanned aerial vehicle preferentially adopts a near field communication protocol for wireless connection, namely, the unmanned aerial vehicle detects a communication mode of a slave near field communication module through a master near field communication module; when the communication mode of the slave near field communication module is the near field communication point-to-point mode, the unmanned aerial vehicle performs point-to-point connection through the master near field communication module and the slave near field communication module within a preset time period to establish bidirectional communication connection between the master near field communication module and the slave near field communication module, so as to obtain a connection result, and further, the unmanned aerial vehicle executes step 204.
It should be noted that, due to the NFC near field communication principle and the bidirectional peer-to-peer communication principle, when two NFC modules (the master near field communication module and the slave near field communication module) approach each other, the two NFC modules recognize each other to realize wireless communication connection.
203. When the distance between unmanned aerial vehicle and the year thing case satisfies the default condition, and when being bluetooth communication connection, carry out the accordant connection through main bluetooth module and follow bluetooth module in predetermineeing long time, obtain the connection result.
It should be noted that, in a bluetooth communication connection application scenario, for the master bluetooth module and the slave bluetooth module, the unmanned aerial vehicle may set the preset condition to be greater than 10 centimeters and less than or equal to 100 centimeters, or may also set to be greater than 10 centimeters and less than or equal to 300 centimeters, which is not limited herein.
Specifically, when unmanned aerial vehicle and carry the distance between the thing case and satisfy the default condition, and when being bluetooth communication connection, unmanned aerial vehicle preferentially adopts bluetooth communication protocol to carry out wireless connection, that is to say, unmanned aerial vehicle passes through main bluetooth module and searches for from bluetooth module, then main bluetooth module pairs with from the bluetooth, obtains the connection result. Specifically, the unmanned aerial vehicle establishes Bluetooth connection with the slave Bluetooth module through the master Bluetooth module, the unmanned aerial vehicle is provided with a Bluetooth communication channel between the master Bluetooth module and the slave Bluetooth module, and then the unmanned aerial vehicle establishes long connection with the slave Bluetooth module through the Bluetooth communication channel. So that when there are multiple bluetooth modules around the master bluetooth module, the master bluetooth module can also distinguish the slave bluetooth module from the multiple bluetooth modules according to whether an active command is received, and then the drone executes step 204.
It can be understood that, the master bluetooth module and the slave bluetooth module both carry out data transmission through the bluetooth communication protocol, and have the characteristics of long transmission distance and high transmission rate. Unmanned aerial vehicle establishes wireless connection through near field communication agreement or bluetooth communication agreement through the distance between automated inspection unmanned aerial vehicle and the year thing case to be applicable to different practical application scenes.
204. And judging whether the connection result is connection failure or not.
The connection failure is used for indicating that the first wireless connection module and the second wireless connection module are failed to pair. Optionally, the unmanned aerial vehicle determines whether to receive the wireless connection response message sent by the second wireless communication module within a preset time period; if the wireless connection response information sent by the second wireless communication module is not received within the preset time, the unmanned aerial vehicle determines that the connection result is a connection failure, and the unmanned aerial vehicle executes step 205; if the wireless connection response message sent by the second wireless communication module is received within the preset time, the unmanned aerial vehicle determines that the connection result is a successful connection, and the unmanned aerial vehicle executes step 206.
205. If the connection result is connection failure, the first wireless communication module and the second wireless communication module are reconnected according to the preset retry times, and the connection is stopped until the preset retry times are larger than the preset threshold or the wireless communication connection is successful.
Unmanned aerial vehicle has improved wireless connection's accuracy through predetermineeing wireless connection retry mechanism. Optionally, if the connection result is a connection failure, the unmanned aerial vehicle sends a wireless communication connection request to the second wireless communication module, where the wireless connection request includes an unmanned aerial vehicle identifier and data authentication information matched with the second wireless communication module, so that the second wireless communication module verifies the data authentication information, and performs matching connection based on the unmanned aerial vehicle identifier to obtain a reconnection result; and the unmanned aerial vehicle adds 1 to the retried times for calculation until the reconnection result is that the connection is successful, or the retried times are equal to the preset retried times, the connection is stopped, and the initial value of the retried times is 0. For example, the preset retry number is 10, the retry number is 9, and if the reconnection result is a connection failure, the drone continues to reconnect; if the reconnection results in successful connection, the drone determines that the reconnection is successful, and the drone executes step 206. If the retry number is 10 and the reconnection result is connection failure, the unmanned aerial vehicle stops connecting and displays early warning information, wherein the early warning information is used for indicating that the wireless connection is abnormal.
Further, if the connection result is connection failure and near field communication connection, the unmanned aerial vehicle switches the master-slave state of the master near field communication module, and reconnects the near field communication module of the unmanned aerial vehicle through the near field communication module of the carrying box within a preset time length to obtain a reconnection result; or if the connection result is connection failure, and is bluetooth communication connection, then unmanned aerial vehicle switches unmanned aerial vehicle's bluetooth module and carries the bluetooth module's of thing case principal and subordinate state to in predetermineeing long time through carrying the bluetooth module reconnection unmanned aerial vehicle's of thing case bluetooth module, obtain the reconnection result.
206. If the connection result is that the connection is successful, data exchange processing is carried out through the first wireless communication module and the second wireless communication module, and the carrying box is controlled to be opened and closed.
It can be understood that, when the connection result is that the connection is successful, the unmanned aerial vehicle determines whether to establish the wireless communication connection through the near field communication connection or the bluetooth communication connection based on the preset wireless communication protocol, and then the unmanned aerial vehicle can adopt the near field communication protocol or can adopt the bluetooth communication protocol to perform data exchange processing, so as to realize data transmission and logistics distribution control on the carrying box. Optionally, if the connection result is that the connection is successful and the connection is near field communication, the unmanned aerial vehicle starts a radio frequency field of the master near field communication module, the unmanned aerial vehicle sends data to the slave near field communication module through the master near field communication module according to a preset transmission rate, and the slave near field communication module receives and processes the data sent by the master near field communication module in an interception mode; when the main near field communication module sends data, the unmanned aerial vehicle closes the radio frequency field of the main near field communication module and starts the monitoring mode of the main near field communication module, and the unmanned aerial vehicle waits for and processes the data sent by the sub near field communication module and carries out on-off control on the carrying box. It should be noted that the same preset transmission rate is adopted for data transmission and reception between the master near field communication module and the slave near field communication module.
