Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a flow chart illustrating a method of wireless remote control according to an exemplary embodiment. As shown in fig. 1, the method includes steps 100 through 102.
In step 100, a first device receives a wireless remote control signal from a second device, wherein the wireless remote control signal comprises a source device identification, a control instruction and a target device identification.
In step 101, the first device compares whether its first device identifier is the same as the target device identifier.
In step 102, the first device acts as a relay device to forward the wireless remote control signal to the target device if the first device identifier is different from the target device identifier.
In this embodiment, the first device and the second device may be smart devices with remote control functions. For example, a smart phone, a tablet computer, a notebook computer, an intelligent household appliance, etc. with a remote control function module installed therein. The devices may communicate with each other via a wireless network. A plurality of intelligent devices with remote control functions can form a wireless remote control network. The first device and the second device are node devices in the wireless remote control network. Each node device can send out wireless remote control signals, can receive wireless remote control signals of other devices, can respond to certain wireless remote control signals to execute corresponding actions, and can also be used as relay equipment to forward the wireless remote control signals. In practical applications, the actions performed by a node device are different, and the role of the node device may be different. For example, the first device may transmit a wireless remote control signal as a source device; the first device can also be used as a relay device to forward the wireless remote control signal; the first device may also execute the control instruction in the wireless remote control signal as a target device.
In this embodiment, the source device identifier and the target device identifier may include, but are not limited to, the following categories: a Media Access Control (MAC) Address of the device, an Internet Protocol (IP) Address of the device, a device name preset by a user, and the like. Taking the device identifier as an IP address as an example, after receiving the wireless remote control signal, the first device parses the wireless remote control signal to obtain IP addresses of the source device and the target device, and the first device may compare whether the IP addresses of the first device and the target device are the same. If not, the first device may forward the wireless remote control signal to the target device. In the present disclosure, if the first device and the target device are close in distance and direct wireless communication is possible, the first device may directly forward the wireless remote control signal to the target device as a relay device. If the first device is far away from the target device and cannot directly perform wireless communication, the first device can relay the wireless remote control signal for multiple times through other relay devices until the wireless remote control signal is forwarded to the target device.
In a possible implementation manner, the forwarding, by the first device, the wireless remote control signal to the target device as a relay device may include: the first device serves as a relay device to forward the wireless remote control signal to the target device in a broadcast mode. For example, the first device may be configured to perform processing such as amplification on the wireless remote control signal and then broadcast the wireless remote control signal to the target device.
In a possible implementation manner, the first device serves as a relay device, and may directly forward the wireless remote control signal to the target device according to the IP address of the target device.
In this embodiment, the first device can be used as a relay device to forward the wireless remote control signal from the second device, thereby extending the remote control operation distance of the device with the remote control function and widening the remote controllable range. In addition, no special relay device is required to be additionally added in the wireless local area network, and any device with the remote control function can be used as the relay device to forward the wireless remote control signal.
It should be noted that, as those skilled in the art will appreciate, there are many methods in the related art to implement Wireless communication between devices, for example, Bluetooth (Bluetooth), Wi-Fi (Wireless-Fidelity, Wireless Fidelity, mobile network communication, etc., which are not limited herein.
Fig. 2 is a flow chart illustrating a method of wireless remote control according to an example of an exemplary embodiment. The difference from the above embodiment is that the method further comprises step 103, as shown in fig. 2.
In step 103, the first device executes the control instruction if the first device identifier is the same as the target device identifier.
For example, if the first device is a smart television, the first device identifier of the smart television is the MAC address of the smart television: 00-0E-09-38-62-A9, the MAC address of the target device is 00-0E-09-38-62-A9, and the control instruction is shutdown. After receiving the wireless remote control signal, the intelligent television compares the MAC address of the intelligent television with the MAC address of the target device, and then executes a shutdown action.
In this embodiment, each node device in the wireless remote control network may serve as a source device to remotely control other devices, may also serve as a relay device to forward a wireless remote control signal remote controller, and may also serve as a destination device to execute control instructions of other devices, flexibly utilize communication resources of each device, and may extend a remote control operation distance of a device having a remote control function without additionally adding a special relay device in the wireless local area network, thereby expanding a remote control range and reducing manual mobile operations.
In one possible implementation, the method further includes: in case the first device receives a plurality of identical wireless remote control signals, one of the plurality of identical wireless remote control signals is retained.
For example, in case the first device receives a plurality of identical wireless remote control signals, the first device may retain the first received wireless remote control signal.
For example, in case the first device receives a plurality of identical wireless remote control signals, the first device may retain the wireless remote control signal with the greatest signal strength.
In this embodiment, the first device retains one wireless remote control signal of the plurality of identical wireless remote control signals, thereby effectively avoiding the first device from repeatedly processing the identical wireless remote control signals, thereby reducing redundant processing and reducing system load.
In one possible implementation, each device in the local area wireless network may remotely control other devices by using any one of the following manners: one-to-one, one-to-many, many-to-one, many-to-many.
The wireless remote control method of the embodiment of the disclosure is beneficial to control of intelligent equipment in intelligent home. Because the signal of the household intelligent equipment is weaker, the signal attenuation is extremely large (the signal range of single equipment is reduced) particularly after the household intelligent equipment is blocked by a wall, and the wireless remote control range can be greatly improved by adopting the method.
Fig. 3 shows an example of an application of the wireless remote control method of the present disclosure to a home intelligent device. The device A is a smart phone, the device B is a smart air conditioner, and the device C is a smart television. The smart mobile phone, the smart air conditioner and the smart television can communicate with each other through wireless networks such as Bluetooth, infrared or WIFI.
The user sends out a wireless remote control signal (air conditioner starting signal for short) for controlling the intelligent air conditioner to start through a wireless network by using remote control software installed in the smart phone. At this moment, the remote control signal range of the smart phone carried by the user cannot directly reach the smart air conditioner, and can reach the smart television. The intelligent television receives the air conditioner starting signal.
The intelligent television compares and finds that the target equipment identification of the air conditioner starting signal is different from the equipment identification of the intelligent television, the intelligent television can send the air conditioner starting signal again (equivalent to automatic relay), and the signal transmission possibly passes through a plurality of equipment relays to finally reach the controlled equipment.
If the remote control signal range of the intelligent television can reach the intelligent air conditioner, after the intelligent air conditioner receives the air conditioner starting signal, comparing whether the own equipment identification is the same as the target equipment identification in the air conditioner starting signal. If the two signals are the same, the intelligent air conditioner executes the starting action.
In this example, the node devices in the wireless remote control network form a mesh network, signals (i.e., wireless remote control signals) can freely transmit in the mesh network, and each node device can forward (relay) the signals; each node device may also transmit signals (i.e., with remote control transmit signal functionality) and execute control instructions for the local device. Therefore, any node equipment in the wireless network can be flexibly used as relay equipment, the remote control operation distance of equipment with a remote control function is prolonged, and the remote control range is expanded. In addition, no special relay device is required to be additionally added in the wireless local area network, and any device with the remote control function can be used as the relay device to forward the wireless remote control signal.
