Embodiment 1

[0068] like figure 1 The remote control method shown can realize the communication between the remote control device and the electronic device. The remote control device is an RF remote control device, such as an RF remote control. The electronic device has a wireless network card chip, such as a TV or a set-top box such as a smartTV. The remote control device adopts the wireless protocol transmission of the 2.4Ghz frequency band, and the two realize data interaction based on the WIFI direct communication protocol, including:

[0069] Step S101: When the remote control device detects a first key command issued on its key matrix, it requests to pair with the electronic device.

[0070] Wherein, the first button command is instruction information sent by the user when connecting the remote control device to the electronic device, specifically, pressing a specific button in the button matrix of the remote control device to request a pairing connection with the electronic device. ...

Embodiment 2

[0108] like Figure 4 The shown remote control method can realize the communication between the remote control device and the electronic device. The difference from the embodiment lies in steps S223~S224. The other steps are consistent with the embodiment 1, specifically including:

[0109] Step S201: When the remote control device detects the first key command issued on its key matrix, it requests to pair with the electronic device; wherein, the first key command is issued by the user when connecting the remote control device to the electronic device The command information is specifically pressing a specific key in the key matrix of the remote control device.

[0110] Step S202: When the pairing request response of the electronic device to the remote control device is valid, the remote control device exchanges keys with the electronic device.

[0111] In step S202, how to determine whether the electronic device responds to the pairing request of the remote control device is...

Embodiment 3

[0126] This embodiment provides a Figure 5 The remote control device shown corresponds to Embodiment 1, and can realize communication with electronic devices, including:

[0127] Button matrix 301;

[0128] Key matrix scanning unit 302, for detecting key commands on the key matrix 301;

[0129] A pairing request unit 303, configured to output a first key command request to be paired with the electronic device 300 according to the key matrix scanning unit 302;

[0130] A key exchange unit 304, configured to exchange keys with the electronic device when the electronic device 300 responds effectively to the pairing request;

[0131] The data interaction unit 305 is configured to perform data interaction with the electronic device 300 when the key exchange is successful.

[0132] The remote control device of this embodiment can be specifically applied to make an RF remote control. The pairing request unit 303, the key exchange unit 304 and the data interaction unit 305 are int...

Abstract

The invention provides a communication system, a remote-control method and remote-control equipment. The remote-control method comprises the following steps: when detecting a first keystroke command given by a keystroke matrix, remote-control equipment requires to be paired with electronic equipment; when the electronic equipment gives an effective response to the pairing request of the remote-control equipment, the remote-control equipment and the electronic equipment achieve key exchange; and when the key exchange is successful, the remote-control equipment and the electronic equipment achieve data exchange. The remote-control equipment comprises a pairing request unit used for pairing with the electronic equipment according to the request of the first keystroke command, a key exchange unit used for key exchange with the electronic equipment and a data interaction unit used for data interaction with the electronic equipment. According to the invention, the remote-control equipment and the electronic equipment can be connected in a pairing manner at all times and places, so that interference caused by WIFI (Wireless Fidelity), Bluetooth and other signals to the communication process is avoided.

Description

technical field [0001] The invention relates to the technical field of remote control, in particular to a communication system, a remote control method and remote control equipment. Background technique [0002] Modern life is inseparable from various electronic devices, such as televisions. Various electronic devices are often placed at a certain distance from the location of the user. To control the electronic device, the user needs a remote control device. For example, the user uses a remote control to control a TV. [0003] In the prior art, infrared remote control devices are commonly used to remotely control electronic devices. Users must aim at the infrared receivers on electronic devices when operating with infrared remote control devices. The infrared receiver on the electronic device is aligned, and the direction of the remote control must also be changed, which is inconvenient to operate. [0004] Furthermore, for large electronic equipment, due to the large siz...
