After introducing the design concept of the embodiment of the present application, some simple descriptions are provided below for application scenarios to which the technical solution of the embodiment of the present application can be applied, and it should be noted that the application scenarios described below are only used for describing the embodiment of the present application and are not limited. In the specific implementation process, the technical scheme provided by the embodiment of the application can be flexibly applied according to actual needs.
As shown in fig. 1, an application scenario diagram provided for the embodiment of the present application is provided, where the application scenario of information processing may include a remote control device 10 and a controlled device 11.
The remote control device 10 may include, among other things, one or more processors 101, at least two signal transceivers 102, and a memory 103. The signal transceiver 102 may be an antenna capable of transmitting and receiving signals, and the memory 102 may store program instructions of the information processing method provided by the embodiment of the present application, which when executed by the processor 101, can be used to implement the steps of the information processing method provided by the embodiment of the present application, so as to establish a communication channel between the remote control device 10 and the controlled device 11.
In this embodiment of the application, when the remote control device 10 receives a remote control operation performed by a user, the processor 101 may generate a remote control instruction corresponding to the remote control operation, and control the plurality of signal transceivers 102 to send a remote control signal carrying the remote control instruction to the controlled device 11, and when any signal transceiver of the plurality of signal transceivers 102 receives a response message of the controlled device 11, the processor 101 establishes a communication channel with the controlled device 11, so as to avoid a technical problem that the controlled device cannot be normally controlled due to user occlusion, thereby greatly improving reliability of the remote control device, further enabling the user not to adjust a holding posture, correspondingly reducing complexity of operation of the remote control device, and improving user experience effects.
Of course, the method provided in the embodiment of the present application is not limited to be used in the application scenario shown in fig. 1, and may also be used in other possible application scenarios, and the embodiment of the present application is not limited. The functions that can be implemented by each device in the application scenario shown in fig. 1 will be described in the following method embodiments, and will not be described in detail herein. Hereinafter, the method of the embodiment of the present application will be described with reference to the drawings.
In the embodiment of the present application, the remote control device 10 may include a housing 104 including a cavity, at least two signal transceivers 102, and a processor 101, wherein the at least two signal transceivers 102 are disposed in the cavity of the housing and located at different ends of the housing, and the processor is disposed in the cavity of the housing and electrically connected to the at least two signal transceivers, respectively; the processor controls the remaining signal transceivers to transmit the remote control signal when any one of the at least two signal transceivers is blocked, so that the processor can control the remaining signal transceivers 102 to transmit the remote control signal to the controlled device 11 when any one of the at least two signal transceivers 102 is blocked. Here, at least two signal transceivers 102 may be 3, 4, or 5, and when the number of signal transceivers 102 is greater than the number of ends of remote control device 10, the number of signal transceivers 102 exceeding the number of ends of remote control device 10 may be arbitrarily set at each end of remote control device 10.
Referring to fig. 2, a schematic layout of a remote control device with 4 signal transceivers is shown, wherein the remote control device 10 may include a housing 104 containing a cavity, 4 signal transceivers 102 and a processor 101, two signal transceivers 102 are respectively disposed at the top end and the tail end of the remote control device 10, and the remaining two signal transceivers 102 are respectively disposed at two sides of the remote control device 10. It can be seen that when any one of the 4 signal transceivers is blocked, a remote control signal can also be transmitted to the controlled device 11 through the remaining 3 signal transceivers 102.
As shown in fig. 3, a schematic structural diagram of a remote control device provided in the embodiment of the present application is shown, wherein a processor 101 may control a plurality of signal transceivers 102 to transmit remote control signals to a controlled device 11. Specifically, when the remote control device receives a remote control operation, the processor 101 generates a remote control instruction corresponding to the remote control operation, controls the plurality of signal transceivers to transmit a remote control signal carrying the remote control instruction, and when any one of the signal transceivers receives a response message of the controlled device, the processor 101 establishes a communication channel with the controlled device; the reply message may be used to indicate that the remote control signal has been received by the controlled device. That is, after the user performs a remote control operation on the remote control device 10, the remote control device 10 receives the remote control operation performed by the user on the remote control device 10, and may generate a remote control instruction corresponding to the remote control operation, for example, a remote control instruction for controlling a television to be turned on, or for controlling a television to be switched.
In one possible embodiment, the remote control device may be a key type device, that is, there is a physical key on the body of the remote control device, and then the remote control operation may be an operation in which a user presses the physical key on the remote control device.
In another possible implementation, the remote control device may be a touch screen type device, that is, the remote control device includes a touch screen, and the remote control operation may be a touch operation performed by a user on the touch screen of the remote control device.
In one possible embodiment, the number of the plurality of signal transceivers may be two in order to reduce the manufacturing cost, and one of the signal transceivers may be disposed at one end of the remote control device 10 and the other signal transceiver may be disposed at the other end of the remote control device 10. As shown in fig. 4, a layout diagram of the remote control device when the number of signal transceivers is two is shown, referring to fig. 4, the signal transmitter 1 is disposed at the top end of the remote control device 10, and the signal transmitter 2 is disposed at the bottom end of the remote control device 10, so that when a user holds the top end of the remote control device 10 and blocks the remote control signal transmitted by the signal transmitter 1, the signal transmitter 2 disposed at the bottom end of the remote control device 10 can transmit the remote control signal to the controlled device 11, so that the remote control device 10 can establish a communication connection with the controlled device 11, thereby avoiding a technical problem that the controlled device cannot be normally controlled due to blocking of the user, greatly improving reliability of the remote control device, and since the user does not need to adjust a holding posture, accordingly reducing complexity of the remote control device, and improving user experience.
In a possible implementation manner, as shown in fig. 5, a schematic structural diagram of a remote control device including a power divider provided in an embodiment of the present application is shown. The remote control device 10 may also include a power divider 105. The power divider 105 may be disposed within the cavity of the housing 104.
Specifically, when the remote control device 10 receives a remote control operation, the processor 101 generates a remote control instruction corresponding to the remote control operation, and sends a remote control signal carrying the remote control instruction to the power divider 105, the power divider 105 generates a plurality of remote control sub-signals based on the remote control signal, and sends each generated remote control sub-signal to the corresponding signal transceiver 102, where each remote control sub-signal carries the remote control instruction, and each remote control sub-signal corresponds to one signal transceiver, for example, the power divider 105 may generate N remote control sub-signals, which are respectively a remote control sub-signal 1, a remote control sub-signal 2, …, and a remote control sub-signal N, the signal transceiver 1 may receive the corresponding remote control sub-signal 1, the signal transceiver 2 may receive the corresponding remote control sub-signal 2, and so on, and each signal transceiver of the N signal transceivers may send its own corresponding remote control sub-signal, therefore, as the signal transceivers are positioned at different ends of the remote control equipment, the transmitting directions of the signal transceivers can be different, and then the remote control instruction can be sent to the controlled equipment no matter which direction the controlled equipment is positioned, so that the reliability of remote control of the remote control equipment is improved.
In practical applications, taking 2 signal transceivers as an example, as shown in fig. 6, which is a schematic diagram of the power divider provided in the embodiment of the present invention, 3 impedances Z1, Z2, and Z3 exist in a signal transmission line inside the power divider 105, an input transmission line corresponds to the impedance Z1, and an output transmission line corresponds to the impedances Z2 and Z3, respectively, it can be seen that the power divider 105 simultaneously generates remote control sub-signals, and further, time for sending the remote control sub-signals to the corresponding signal transceivers 102 is also the same, therefore, in order to improve reliability of the remote control device 10 and reduce power consumption, the processor 101 may be configured to control a plurality of signal transceivers 102 to send the remote control sub-signals to the controlled device 11 at the same time, so that when one signal transceiver 102 is blocked, another signal transceiver 102 can also send the remote control signals to the controlled device 11.
In practical applications, when the power divider 105 divides the remote control signal into a plurality of remote control sub-signals, as shown in fig. 4, since there is impedance on the signal transmission line, there is usually a phenomenon of signal attenuation, and therefore the signal strength of the plurality of remote control sub-signals is generally smaller than that of the original remote control signal.
Specifically, the difference between the signal strengths of any two remote control sub-signals in the plurality of remote control sub-signals generated by the power divider 105 is within a preset range, that is, the signal strengths of different remote control sub-signals may be equal, that is, the power divider equally divides the remote control signal into N remote control sub-signals, and the signal strength of each remote control sub-signal is not greater than the signal strength of the remote control signal. Here, the preset range may be a preset error allowable range.
For example, when the preset range is [0, 0.5] and the remote control signal is 20dBm, the power divider 105 may be used to generate 4 remote control sub-signals, which are 17dBm, 16.9dBm, 17.1dBm, and 17.1dBm, respectively, and it can be seen that the difference between the signal strengths of any two remote control sub-signals in the 4 remote control sub-signals is less than 0.5dBm, and the 4 remote control sub-signals are less than 20 dBm.
In a possible implementation manner, as shown in fig. 7, for a schematic structural diagram of a remote control device including a signal switch provided in an embodiment of the present application, the remote control device 10 may further include a signal switch 106, and the signal switch 106 may be disposed in the cavity of the housing 104, where the signal switch 106 may include one input port and N output ports, and one output port corresponds to one signal transceiver.
Specifically, when the remote control device 10 receives a remote control operation, the processor 101 generates a remote control command corresponding to the remote control operation, and controls the signal switch 106 to switch the output port in a polling switching manner, so as to send a remote control signal carrying the remote control command to a corresponding signal transceiver through one of the output ports of the signal switch 106.
Since each polling handover procedure is basically the same, the following description will be made on how to perform communication channel establishment specifically in one polling handover procedure.
Specifically, the processor 101 may first control the input port to communicate with one of the output ports, for example, control the input port to communicate with the output port 1, and then may transmit the remote control signal at least once through the signal transceiver 1 corresponding to the output port 1, for example, may transmit the remote control signal to the controlled device 11 3 times.
When the signal transceiver 1 does not receive the response message of the controlled device 11 in the preset response period, the processor 101 controls the input port to communicate with the output port 2, so as to transmit the remote control signal through the signal transceiver 2 corresponding to the output port 2, similarly, it is also determined that the signal transceiver 2 does not receive the response message of the controlled device 11 in the preset response period, if the response message is not received, the processor 101 controls the input port to communicate with the output port 3, so as to transmit the remote control signal through the signal transceiver 2 corresponding to the output port 3, and so on.
When the signal transceiver 1 receives the response message within the preset response period, the processor 101 establishes a communication channel with the controlled device 11, and the polling switching process is stopped.
Here, taking the number of the plurality of signal transceivers as two as an example, as shown in fig. 8, it is a schematic structural diagram of the remote control device when the number of the signal transceivers is two, wherein the remote control device includes a first signal transceiver (i.e., the signal transceiver 1 shown in fig. 8) and a second signal transceiver (i.e., the signal transceiver 2 shown in fig. 8) to perform transmission of the remote control signal and reception of the response message. At this time, the signal switch may adopt a Single Pole Double Throw (SP 2T) rf switch, and the switch SP2T has 2 output ports, so that when the switch SP2T is operated, the remote control signal can be outputted from one of the 2 output ports.
Specifically, the processor 101 may control the input port of the signal switch 106 to communicate with a first output port (i.e., the output port 1 shown in fig. 8) so as to transmit the remote control signal at least once through a first signal transceiver corresponding to the first output port, for example, transmit the remote control signal 3 times to the controlled device 11 through the first signal transceiver.
When the first output port does not receive the response message of the controlled device 11 within the preset response period, the processor 101 controls the switch SP2T to switch such that the input port is communicated with the second output port (i.e. the output port 2 shown in fig. 8) to transmit the remote control signal through the second signal transceiver corresponding to the second output port, for example, transmit the remote control signal to the controlled device 11 3 times through the signal transceiver 2 shown in fig. 8.
If the second signal transceiver does not receive the response message of the controlled device 11 within the preset response period, the processor 101 controls the input port to communicate with the first output port again, so as to transmit the remote control signal at least once again through the first signal transceiver corresponding to the first output port. The first signal transceiver and the second signal transceiver alternate remote control signal transmission and reply message determination in this way until a reply message of the controlled device 11 is received, and the cyclic polling switching process stops.
In a possible implementation, in order to accurately control the signal switch and improve the reliability of the remote control device 10, as shown in fig. 9, a connection diagram for controlling the signal switch by a processor according to an embodiment of the present application is provided, wherein the processor 101 may include a first General-purpose input/output port 1 and a second General-purpose input/output port 2, and during an actual application, it may be determined whether the General-purpose input/output (GPIO) port is selected for use by determining high and low levels of a pin corresponding to the GPIO port, so as to transmit a signal switching command through the port.
Specifically, the processor 101 may control the first general purpose input/output port GPIO 1 to be electrically connected to the control port of the signal switch 106, and send a signal switching command indicating a switching state of the signal switch 106 to the signal switch 106 through the first general purpose input/output port GPIO 1, so as to control the input port to communicate with the first output port; further, the processor 101 can send the remote control signal to the input port of the signal switch 106 and send the remote control signal to the signal transceiver 102 through the first output port of the signal switch 106.
Furthermore, when the response message of the controlled device 11 is not received within the preset response period, the processor 101 controls the second general input/output port GPIO 2 to be electrically connected to the control port of the signal switch 106, and sends a signal switching command to the signal switch 106 through the second input/output port GPIO 2 to control the input port to be communicated with the second output port. Therefore, even if one universal input/output port fails, the signal switching command can be sent through other universal input/output ports, and the reliability of the remote control device 10 is further improved.
In one possible implementation, in order to enrich the types of the remote control device 10, the remote control device 10 in the present application is suitable for more application scenarios, and therefore, the signal transceiver used may be a WIreless Fidelity (WIFI) signal transceiver, a bluetooth signal transceiver, a internet of things (zigbee) signal transceiver, a long range (LoRa) signal transceiver, or an Ultra Wide Band (UWB) signal transceiver, etc. Furthermore, the remote control device 10 of the present application can be applied to various wireless remote control occasions, and the application range is wide. Next, an information processing method provided in the embodiment of the present application is described with reference to the remote control device 10, as shown in fig. 10, which is a schematic flow chart of the information processing method provided in the embodiment of the present application, and the method can be executed by, for example, a processor of the remote control device 10, and the flow of the method is described as follows.
Step 1001: when a remote control operation for the remote control device is received, a remote control instruction corresponding to the remote control operation is generated.
In embodiments of the present application, the remote control device may include a plurality of signal transceivers, and at least two signal transceivers of the plurality of signal transceivers are located at different ends of the remote control device.
Step 1002: and sending the remote control signal carrying the remote control command to the plurality of signal transceivers so as to transmit the remote control signal carrying the remote control command through the plurality of signal transceivers.
In this embodiment, after the remote control command corresponding to the remote control operation is generated, the remote control command may be loaded in a carrier signal to obtain a remote control signal capable of carrying the remote control command, and the remote control signal may be further sent to the multiple signal transceivers, so that the multiple signal transceivers may transmit the remote control signal to the controlled device.
Step 1003: it is determined whether any of the plurality of signal transceivers receives a reply message of the controlled device.
In the embodiment of the present application, after transmitting a remote control signal to a controlled device, in order to determine whether the transmitted remote control signal has been received by the controlled device, the remote control device detects whether any of the plurality of signal transceivers of the remote control device has received a response message indicating that the controlled device has received the remote control signal.
Step 1004: and establishing a communication channel with the controlled device when the response message of the controlled device is determined to be received.
In the embodiment of the present application, when it is determined that the response message of the controlled device is received, a communication channel may be established between the remote control device and the controlled device. Otherwise, the communication channel is not established.
In a possible implementation manner, when the remote control device may further include a power divider, as shown in fig. 11, another flow chart of the information processing method provided in the embodiment of the present application is described below by taking the remote control device as a "television remote controller", a remote control operation as "pressing a television program change button of a television", and a controlled device as a "television", where a specific flow chart is described below.
Step 1101: when a pressing operation for a television remote controller is received, a television program replacing instruction corresponding to the pressing operation is generated.
Specifically, when the user wants to change the tv program, the user may press a tv program change button on the tv remote controller, and then, when the user presses the tv remote controller, a remote control instruction corresponding to the press operation and capable of being used to change the tv program may be generated.
Step 1102: and sending the remote control signal bearing the remote control instruction to the power divider, and generating a plurality of remote control sub-signals through the power divider.
Specifically, after the remote control instruction corresponding to the pressing operation is generated, the remote control instruction may be loaded in a carrier signal to obtain a remote control signal capable of bearing the remote control instruction, and then the remote control signal may be sent to the power divider, so that the power divider may generate a plurality of remote control sub-signals based on the remote control signal, where each remote control sub-signal bears the remote control instruction.
Step 1103: and sending the plurality of remote control sub-signals to corresponding signal transceivers, and transmitting the corresponding remote control sub-signals through each signal transceiver.
Specifically, after the power divider generates the plurality of remote control sub-signals, the remote control sub-signals may be sent to the corresponding signal transceivers, so that the plurality of signal transceivers may transmit the remote control sub-signals to the controlled device. Each remote control sub-signal may correspond to one signal transceiver, and each signal transceiver may transmit a corresponding remote control sub-signal at the same time.
Step 1104: it is determined whether any of the plurality of signal transceivers received a television response message.
Step 1105: and when the response message of the television is determined to be received, establishing a communication channel between the television remote controller and the television.
Specifically, when it is determined that the response message of the television is received, a communication channel between the television remote controller and the television can be established, so that the user can enable the television to change the television program through the television remote controller. Otherwise, the process returns to step 1101, and the user presses the tv program replacement button on the tv remote controller again.
