Abstract
The present invention is radio adapter of electronic equipment and its radio signal switching method. The radio adapter includes one control circuit, one code module, one radio transceiver module and one universal adaptor. After the control circuit receives signal from some electronic equipment, the code module encodes the signal based on preset distinguishing code and the encoded signal is transmitted via a radio transceiver module to remote adapter with the same architecture. When the adaptor receives via the radio transceiver module the responding signal, the code module decodes the signal and searches the corresponding distinguishing code. Then, the responding signal for the distinguishing code is transmitted to matched electronic equipment for subsequent treatment to reach the aim of radio transmission.
Description
Technical field
The present invention relates to the wireless converting technology, especially a kind of the employing with the mode of inserting with usefulness is with the wireless swticher and the wireless signal forwarding method of the electronic equipment that substitutes wired data transmission means that electric room commonly uses.
Background of invention
Computer is for the data transfer mode between peripheral equipments such as main frame and printer, screen, modem, scanner traditionally, how to transmit with data line, as shown in Figure 1, main frame itself except power line, may with many peripheral equipments mutually in succession, therefore, cause the I/O port winding displacement confusion on the main frame, in addition, if because of the restriction of ornament space or because of the deficiency of the general data line length that is sold on the market, mostly only peripheral equipment is installed near main frame, can't be placed far-end.
Though, some radio transmitting devices have been developed in recent years, for example at present the most normal by infrared transmission technology that industry adopted, as shown in Figure 2, can solve above problem, but this technology of installing is arranged on the only newer usually equipment, but, if reach convenience, aesthetic property and all equipment is eliminated trade-in may increase the burden on the cost, in addition, we are not difficult to find that these radio transmitting devices only are installed in main frame usually, and corresponding peripheral equipment does not have this function, makes to become radio transmitting device on this main frame lack scope for their abilities.
Even all equipments all have the infrared transmission function, but with the sight of present science and technology, the transmission coverage of this infrared technology is the 1-2 chi only, its transmission means is adopted the orthoscopic transmission, must launch by the alignment orientation straight line, angular deflection can not surpass positive and negative 15 degree angles, for furnish peripheral equipment remote than main frame or that angular deflection is too big because of environmental limitations, to lose its transmission property and remote control, and its transmission point only can man-to-manly transmit, add when transmission any secret mode of tool not, easily intercepted for the transmission of important information.
Summary of the invention
The data transmission means of commonly using, its winding displacement is disorderly and unsystematic, its peripheral equipment can't be placed far-end, and most electronic equipment is neither to have radio transmitting device, can not be based on cost consideration with it all displacement, and its transmission means can't one-to-many, the comprehensive transmission of multi-to-multi, in view of this, inconvenience and the shortcoming brought at above-mentioned present situation, the inventor is through the permanent research and experiment of making great efforts, finally development and Design goes out the wireless swticher and the wireless signal forwarding method of a kind of electronic equipment of the present invention, this adapter can be connected in the output of an electronic equipment and go into the connectivity port, and by wireless communication technique, provide various electronic equipments (printer for example, host computer, digital camera, the wireless transmission of the numerical data scanner etc.).
