First embodiment
Fig. 3 shows a block diagram of a remote control device 120 according to an embodiment of the present invention. The remote control device 120 includes: the device comprises a detection module 121, a sending module 122 and a switching module 123.
The detecting module 121 is configured to detect a clicked operation of the control 101 of the remote control device 120.
In this embodiment, when the user clicks the control 101 on the touch screen 103, the detection module 121 can detect the clicked operation of the control 101. The display state of the control 101 may prompt the user about the current state of the controlled device 200, for example, by displaying text to prompt the user about the current state of the controlled device 200, for example, the display state of the control 101 is "take off", then the controlled device 200 performs the take off action in the next step, and the current state of the controlled device 200 is "ground"; or the control 101 prompts by displaying different icons, such as a circle representing the current state of the controlled device 200 in the take-off, a rectangle representing the current state of the controlled device 200 in the hover, and so on.
When the remote control device 120 is connected to the UDP server 201 on the controlled device 200 through the wireless network 300 (e.g., wiFi), the detection module 121 may also detect whether the remote control device 120 is successfully connected to the controlled device 200, and when the remote control device 120 is disconnected from the controlled device 200, the detection module 121 may send a prompt message to remind the user of the connection state of the remote control device 120 and the controlled device 200.
Further, the detecting module 121 is further configured to detect current status data of the controlled device 200. After the remote control device 120 is successfully connected to the controlled apparatus 200, the UDP server 201 continuously feeds back the current status data of the controlled apparatus 200 to a fixed port (e.g., a wireless data receiving interface) of the remote control device 120 in a transmission manner of a User Datagram Protocol (UDP) through a Socket. The remote control 120 can detect the current status data of the controlled device 200 through the fixed port. Specifically, the current state data fed back by the UDP server 201 to the remote control device 120 is a data compression packet, after the remote control device 120 receives the data compression packet fed back by the UDP server 201, the data compression packet needs to be unpacked, where the data compression packet includes a packet header, a packet body, and a check, the current state data of the controlled device 200 is stored in the packet body, and the current state data of the controlled device 200 is obtained after unpacking.
In this embodiment, the current state data of the controlled apparatus 200 may be: the data defining the current state of the controlled device 200 is stored in the UDP server 201 of the controlled device 200 according to a predetermined protocol. For example, the current state of the controlled device 200 is defined as follows according to a predetermined protocol:
TABLE 1
| Current state of | In flight | Ground surface | During take-off | During landing | In hover |
| Current state data | 0 | 1 | 2 | 3 | 4 |
As shown in table 1, when the current state of the controlled apparatus 200 is in flight, ground, take-off, landing, hovering, respectively, its current state data corresponds to 0, 1, 2, 3, 4, respectively. These current status data may be stored in the UDP server 201 on the controlled device 200 and used for transmission to the remote control 120. For example, when the controlled apparatus 200 is in takeoff, the UDP server 201 transmits the current status data "2" to the remote control 120; when the controlled device 200 is hovering, the UDP server 201 transmits the current status data "4" to the remote control 120.
The sending module 122 is configured to respond to the clicked operation of the control 101, call an operation instruction matched with the control 101, and send the operation instruction to the controlled device 200.
In this embodiment, the control 101 and the operation instruction may be matched in advance, and the matched operation instruction is stored in the memory 102 of the remote control terminal 100, and when the detection module 121 detects the clicked operation of the control 101, the sending module 122 calls the operation instruction matched with the control 101 from the memory 102 of the remote control terminal 100 and sends the operation instruction to the UDP server 201 of the controlled device 200 in response to the clicked operation of the control 101. For example, the display state of the control 101 is "take-off", and then the operation instruction matched with the control 101 is "take-off instruction", which is stored in the memory 102 of the remote control terminal 100. When the detection module 121 detects the clicked operation of the control 101 with the display state of "take-off", the "take-off instruction" is called from the memory 102 of the remote control terminal 100 and sent to the UDP server 201 of the controlled device 200. After receiving the "take-off instruction", the UDP server 201 parses and transmits the "take-off instruction" to the controlled device 200, so that the controlled device performs a take-off action corresponding to the "take-off instruction".
The switching module 123 is configured to switch the display state of the control 101 in response to the current state data fed back by the controlled device 200 according to the operation instruction.
In this embodiment, after the controlled device 200 receives the operation instruction sent by the sending module 122, the current state is changed according to the operation instruction, and the current state data of the controlled device 200 is fed back to the switching module 123 through the UDP server. The switching module 123 switches the display state of the control 101 according to the current state data.
For example, after the controlled device 200 receives the "take-off instruction" sent by the sending module 122, the take-off action is performed according to the "take-off instruction", the controlled device 200 starts taking off from the ground, the current state of the controlled device 200 changes from "ground" to "taking-off in the process, and the current state data of the controlled device 200 changes from" 1 "(ground) to" 2 "(taking-off). Then, the UDP server 201 of the controlled device 200 feeds back the current state data "2" of the controlled device 200 to the switching module 123 of the remote control 120, and based on the current state data "2", the switching module 123 can learn that the controlled device 200 is already in take-off, and the next step does not need to be further performed on the control 101 whose display state is "take-off", so that the display state "take-off" of the control 101 is switched to the next display state "drop".
Second embodiment
Fig. 4 shows a flowchart of a remote control method according to an embodiment of the present invention. The remote control method provided by the embodiment of the invention comprises the following steps:
in step S1, the clicked operation of the control 101 of the remote control device 120 is detected.
In this embodiment, step S1 may be performed by the detection module 121 of the remote control device 120. When the user clicks the control 101 on the touch screen 103, the detection module 121 can detect the clicked operation of the control 101. The display state of the control 101 may prompt the user about the current state of the controlled device 200, for example, by displaying text to prompt the user about the current state of the controlled device 200, for example, the display state of the control 101 is "take off", then the controlled device 200 performs the take off action in the next step, and the current state of the controlled device 200 is "ground"; or the control 101 prompts by displaying different icons, such as a circle representing the current state of the controlled device 200 in the take-off, a rectangle representing the current state of the controlled device 200 in the hover, and so on.
When the remote control device 120 is connected to the UDP server 201 on the controlled device 200 through the wireless network 300 (e.g., wiFi), the detection module 121 may also detect whether the remote control device 120 is successfully connected to the controlled device 200, and when the remote control device 120 is disconnected from the controlled device 200, a prompt message may also be sent through the detection module 121, so as to remind the user of the connection state of the remote control device 120 and the controlled device 200.
Further, the current state data of the controlled device 200 may also be detected by the detection module 121. After the remote control device 120 is successfully connected to the controlled apparatus 200, the UDP server 201 continuously feeds back the current status data of the controlled apparatus 200 to a fixed port (e.g., a wireless data receiving interface) of the remote control device 120 in a transmission manner of a User Datagram Protocol (UDP) through a Socket. The remote control 120 can detect the current status data of the controlled device 200 through the fixed port.
In this embodiment, the current state data of the controlled apparatus 200 may be: data defining the current state of the controlled device 200 according to a predetermined protocol, for example: when the current state of the controlled device 200 is in flight, ground, take-off, landing, hovering, respectively, the current state data thereof corresponds to 0, 1, 2, 3, 4, respectively. These current status data may be stored in the UDP server 201 on the controlled device 200 and used for transmission to the remote control 120.
And step S2, responding to the clicked operation of the control 101, calling an operation instruction matched with the control 101 and sending the operation instruction to the controlled equipment 200.
In this embodiment, step S2 may be performed by the transmitting module 122 of the remote control device 120. The control 101 and the operation instruction may be matched in advance, and the matched operation instruction is stored in the memory 102 of the remote control terminal 100, and when the detection module 121 detects the clicked operation of the control 101, the sending module 122 calls the operation instruction matched with the control 101 from the memory 102 of the remote control terminal 100 and sends the operation instruction to the UDP server 201 of the controlled device 200 in response to the clicked operation of the control 101. For example, the display state of the control 101 is "take-off", and then the operation instruction matched with the control 101 is "take-off instruction", which is stored in the memory 102 of the remote control terminal 100. When the detection module 121 detects the clicked operation of the control 101 with the display state of "take-off", the "take-off instruction" is called from the memory 102 of the remote control terminal 100 and sent to the UDP server 201 of the controlled device 200. After receiving the "take-off instruction", the UDP server 201 parses and transmits the "take-off instruction" to the controlled device 200, so that the controlled device performs a take-off action corresponding to the "take-off instruction".
Step S3, responding to the current state data fed back by the controlled device 200 according to the operation instruction, and switching the display state of the control 101.
In the present embodiment, step S3 may be performed by the switching module 123 of the remote control device 120. After receiving the operation instruction sent by the sending module 122, the controlled device 200 changes the current state according to the operation instruction, and feeds back the current state data of the controlled device 200 to the switching module 123 through the UDP server. The switching module 123 switches the display state of the control 101 according to the current state data.
For example, after the controlled device 200 receives the "take-off instruction" sent by the sending module 122, the take-off action is performed according to the "take-off instruction", the controlled device 200 starts taking off from the ground, the current state of the controlled device 200 changes from "ground" to "taking-off in the process, and the current state data of the controlled device 200 changes from" 1 "(ground) to" 2 "(taking-off). Then, the UDP server 201 of the controlled device 200 feeds back the current state data "2" of the controlled device 200 to the switching module 123 of the remote control 120, and based on the current state data "2", the switching module 123 can learn that the controlled device 200 is already in take-off, and the next step does not need to be further performed on the control 101 whose display state is "take-off", so that the display state "take-off" of the control 101 is switched to the next display state "drop".
After the display state of the control 101 is switched, the process returns to step S1, and steps S1 to S3 are continuously performed, namely: detecting a clicked operation of the control 101 of the remote control device 120; responding to the clicked operation of the control 101, calling an operation instruction matched with the control 101 and sending the operation instruction to the controlled equipment 200; and responding to the current state data fed back by the controlled equipment 200 according to the operation instruction, and switching the display state of the control 101. In this way, the display state of the control 101 can be continuously switched and the matched operation instruction can be invoked according to the current state data of the controlled device 200, so as to realize the function of multiplexing the same control.
Third embodiment
Fig. 5 shows a detailed flowchart of a remote control method for remotely controlling a unmanned aerial vehicle according to an embodiment of the present invention. The remote control process of this embodiment is a process in which the unmanned aerial vehicle takes off from the ground and lands on the ground.
Firstly, starting the remote control terminal 100, starting the connection between the remote control device 120 and the unmanned aerial vehicle through wifi, and detecting whether the connection between the remote control device 120 and the unmanned aerial vehicle is successful or not by a detection module 121 of the remote control device 120, if the connection is unsuccessful, the display state of the control 101 is 'take off' but can not be clicked; if the connection is successful, the display state of the control 101 is "take off", and at this time, the current state data fed back to the remote control 120 by the unmanned aerial vehicle is "1" (ground). The detecting module 121 continues to detect the clicked operation of the control unit 101 in real time.
Then, the user clicks the control 101 with the display state of "take off", the detection module 121 detects the clicked operation of the control 101, and invokes the "take off instruction" through the sending module 122 and sends the "take off instruction" to the unmanned aerial vehicle.
The unmanned aerial vehicle receives the take-off instruction and executes take-off action. When the unmanned aerial vehicle starts taking off, the current state of the unmanned aerial vehicle is changed from the ground to the taking off, and the current state data of the unmanned aerial vehicle is changed from 1 to 2. After the detection module 121 detects the current status data "2" issued by the unmanned aerial vehicle, the switching module 123 switches the display status of the control 101 from "take off" to "landing".
The unmanned aerial vehicle automatically hovers in the air when flying to a preset height, and the automatic hovering action of the unmanned aerial vehicle after taking off can be preset without controlling the unmanned aerial vehicle to hover through the remote control device 120. For example, the take-off altitude is preset to be 1m, and then the unmanned aerial vehicle automatically hovers in the air when flying to 1 m. At this time, the current state of the unmanned aerial vehicle is changed from "in take-off" to "in hover", the current state data of the unmanned aerial vehicle is changed from "2" to "4", and then the unmanned aerial vehicle transmits the current state data "4" to the remote control 120. At this time, since the action of automatic hovering after the unmanned aerial vehicle takes off is preset, the remote control device 120 does not switch the display state of the control 101 according to the current state data "4", and the display state of the control 101 is still "landing".
Then, the user clicks the control 101 with the current display state of "drop", the detection module 121 detects the clicked operation of the control 101, and the sending module 122 invokes the "drop instruction" to send to the unmanned aerial vehicle.
The unmanned aerial vehicle receives the landing instruction and executes the landing action. When the unmanned aerial vehicle starts to fall, the current state of the unmanned aerial vehicle is changed from 'hovering' to 'falling', and the current state data of the unmanned aerial vehicle is changed from '4' to '3'. After the detection module 121 detects the current state data "3" fed back by the unmanned aerial vehicle, the switching module 123 switches the display state of the control 101 from "landing" to "hovering".
Then, the user clicks the control 101 with the current display state of "hover", the detection module 121 detects the clicked operation of the control 101, and the "hover instruction" is called by the sending module 122 and sent to the unmanned aerial vehicle.
The drone receives the "hover instruction" and performs the hover action. When the unmanned aerial vehicle begins to hover, the current state of the unmanned aerial vehicle is changed from 'in-landing' to 'in-hovering', and the current state data of the unmanned aerial vehicle is changed from '3' to '4'. After the detection module 121 detects the current state data "4" fed back by the unmanned aerial vehicle, the switching module 123 switches the display state of the control 101 from "hover" to "drop".
Then, the user clicks the control 101 with the current display state of "drop", the detection module 121 detects the clicked operation of the control 101, and the sending module 122 invokes the "drop instruction" to send to the unmanned aerial vehicle.
The unmanned aerial vehicle receives the landing instruction and executes the landing action. When the unmanned aerial vehicle starts to fall, the current state of the unmanned aerial vehicle is changed from 'hovering' to 'falling', and the current state data of the unmanned aerial vehicle is changed from '4' to '3'. After the detection module 121 detects the current state data "3" fed back by the unmanned aerial vehicle, the switching module 123 switches the display state of the control 101 from "landing" to "hovering".
Finally, the user does not click the control 101 any more, but makes the unmanned aerial vehicle land directly to the ground, at this time, the current state of the unmanned aerial vehicle changes from "in-landing" to "ground", and the current state data of the unmanned aerial vehicle changes from "3" to "1". After the detection module 121 detects the current state data "1" fed back by the unmanned aerial vehicle, the switching module 123 switches the display state of the control 101 from "hover" to "take-off". Thus, the whole remote control process from take-off to landing of the unmanned aerial vehicle is completed.
In the above, during the landing process of the unmanned aerial vehicle, according to the current state data of the unmanned aerial vehicle, the display state of the control 101 is continuously switched between "hover" and "landing", and the sending module 122 continuously invokes the "hover instruction" or the "landing instruction" matched with the control 101, so as to control the unmanned aerial vehicle to continuously switch between hover and landing actions. If the user does not click on the control 101 with a display state of "hover" during the landing of the unmanned aerial vehicle, the unmanned aerial vehicle may also land directly on the ground without a hover process.
In this embodiment, if WiFi is suddenly disconnected during the flight of the unmanned aerial vehicle, the display state of the control 101 is the state before disconnection, and the detection module 121 prompts the user that WiFi has been disconnected. When the WiFi is connected again, the remote control device 120 obtains current state data of the unmanned aerial vehicle, and switches to a corresponding display state of the control 101.
According to the embodiment of the invention, the display state of the control is continuously switched and the matched operation instruction is invoked according to the current state data of the unmanned aerial vehicle, so that the integration of three keys of take-off, hovering and landing can be realized, and the same control is multiplexed according to different conditions, so that the screen space can be fully utilized, a larger video preview picture can be provided, and screen interference items can be reduced. By adopting the method, the current state of the unmanned aerial vehicle can be clearly reflected according to the display state of the control, and the user experience is improved. And the control is smoothly switched in the whole remote control process, and the whole effect is good.
