Problems solved by technology

However, the current wireless ultra-wideband (UWB) technology cannot meet the needs of digital home networks. The main problem is that the transmission speed drops sharply with the increase of transmission distance.
Therefore, the existing digital home equipment control systems all use the remote controller to control the terminal equipment in a straight line, and cannot control the terminal equipment that cannot be reached by a straight line.

Embodiment Construction

[0028] 1 to 3 show embodiments of the present invention. A radio frequency controller connected to the central host is arranged within the control range of the digital home network, and a radio frequency repeater for forwarding and controlling the radio frequency signals of the source and destination equipment to expand the radio frequency communication distance is arranged within the network control range. As shown in Figure 1, the RF repeater forms a wireless local network with the remote controller and the RF controller through the RF signal, and expands the scope of the original control through the extension of the RF signal. Radio frequency communication follows a unified communication protocol.

[0029] The RF repeater includes the following sub-modules:

[0030] The radio frequency signal transceiver sub-module is used to realize the transmission and forwarding of radio frequency signals;

[0031] The signal processing sub-module is used for analyzing and processing t...

Abstract

The method includes steps: setting up radio controller connected to central host in digital household network; laying out radio repeaters in use for forwarding radio signal between source and destination device (DD); building up wireless local area network composed of radio repeaters, remote controller, and radio controller through radio signal; when receiving data packet needed to reply, if receiving response from DD within repeater delay time (RDT), radio repeater does not need to relay the signal; if not receiving response, then radio repeater forwards data packet; when receiving broadcast data not needed to reply, then radio repeater forwards data packet after RDT. When radio data are unable to reach DD caused by distance or other reasons, the invention uses radio repeater to relay radio signal so as to guarantee that user can control each household device effectively in larger spatial dimension.

Description

technical field [0001] The invention relates to the technical field of digital home equipment control, in particular to a method for realizing remote control of digital home network equipment by using a radio frequency repeater. Background technique [0002] Intelligent digital home refers to a new technology that connects personal computers, home appliances, security systems, lighting systems and wide area networks within the family. The purpose is to enable information sharing and mutual cooperation between PCs, home appliances and other tools. , so that the user can easily grasp the situation of the home device and make the home device better serve the user. Compared with the traditional family, the intelligent digital home can bring people a convenient, safe, intelligent and comfortable digital life. [0003] The intelligent digital home is a complete system, and its realization not only requires digital equipment, but also depends on the broadband network environment a...
