Described frequency variation produces controller 22 and installs respectively in the body of each electronic equipment 2, utilize frequency variation to produce the start-up operation of controller 22, set or change different independent signal frequency in electronic equipment 2 default the transmitting with the random number producing method, and launch described unlike signal frequency and offer described receiving element 11 and receive and storage, the judgement comparison that transmits as each electronic equipment in the future.
The input data of different independent signal frequency and electronic equipment 2 were merged into the data-signal of a succession of transmission emission during described each electronic equipment 2 transmitted, comprise equipment identification code (PID) and time identification code (ID) in the described signal frequency, as shown in Figure 2, wherein the equipment identification code is each electronic equipment 2, the identification code that sets when dispatching from the factory as mouse, keyboard, remote controller, acoustic input dephonoprojectoscope etc., therefore may there be identical equipment identification code in identical mouse electronic equipment.And inferior identification code, then producing controller 22 by device at each electronic equipment 2 intrinsic frequency variation produces with random number way, to produce each electronic equipment 2 independent and different identification code, and equipment identification code and time identification code are rearranged by a plurality of positions respectively, in specific embodiment, can adopt 4bit, 5bit, 6bit ... Deng, can obtain 24 respectively like this, 25,26 ... the composition of individual different permutation code, make a plurality of electronic equipments 2 to rearrange the unlike signal frequency by different equipment identification codes and time identification code, the input data signal of each electronic equipment 2 emission can the phase mutual interference like this.
Described frequency variation produces controller 22, in specific embodiment framework shown in Figure 1, it is an operating key, device is at described each electronic equipment 2, on the body as mouse, keyboard, remote controller, acoustic input dephonoprojectoscope, the user can easily be pushed by operating key, the electronic equipment 2 that has installed frequency variation generation controller 22 is produced independent and different signal frequencies, and to receiving element 11 emissions, and with the judgement comparison of its storage as future.
The framework of the device that disturbs according to the avoiding transmitting-receiving frequency of electronic equipment of embodiment of the present invention below illustrates the operating process of the method that the avoiding transmitting-receiving frequency of electronic equipment of the specific embodiment of the invention disturbs by Fig. 3.The method that this avoiding transmitting-receiving frequency of electronic equipment disturbs comprises:
The frequency signal setting process of each electronic equipment 2, as shown in Figure 3, this process step is:
The user starts learning controller 12, and as flow process 300, this startup can pushing or starting network bridging software controller and enter study module by learning key.
The frequency variation of user's started by press device on electronic equipment 2 bodies produces controller 22, and as flow process 302, receiving element 11 carries out the scanning of frequency simultaneously.
The frequency variation of pushing on electronic equipment 2 bodies produces controller 22, produces the independent and different signal frequency of this electronic equipment with the random number producing method automatically, and this electronic equipment is to receiving element 11 these signal frequencies of emission, as flow process 304.
The receiving element 11 that connects main frame 1 receives the signal frequency that electronic equipment 2 emissions produce, and each signal frequency is write Blastable Read Only Memory respectively stores, as flow process 306.
Finish the study and the storage of the different signal frequency of each electronic equipment 2, learning controller 12 and frequency variation are produced controller 22 close, as flow process 308.
After the signal frequency of described each electronic equipment 2 is set, when the data of signal frequency that comprises setting in a succession of data-signal of each electronic equipment 2 emissions and input or control command, this consecutive data-signal receives and is sent to main frame 1 through receiving element 11, main frame 1 can utilize previous study, write the signal frequency of a plurality of electronic equipments 2 that are stored in Blastable Read Only Memory, judge comparison, determine the signal frequency of this reception by which electronic equipment 2 is launched, because each electronic equipment has different signal frequencies, even when the data of operation input or command signal, can not produce mutual interference among signals at the same time yet.
The judgement discrimination method of described signal emitting identification sign indicating number, it at first is the identification of carrying out the equipment identification code, because each electronic equipment 2, as mouse, keyboard, remote controller, acoustic input dephonoprojectoscope to go out the plant identification code all different, can judge that it is mouse, keyboard, remote controller or acoustic input dephonoprojectoscope by the equipment identification code; And a plurality of mouses, a plurality of keyboards, a plurality of remote controllers or a plurality of acoustic input dephonoprojectoscope, to go out the plant identification code all identical because of it, then must be further judge it is which mouse in a plurality of mouses by inferior identification code, or a plurality of keyboards, a plurality of remote controllers, which keyboard in a plurality of acoustic input dephonoprojectoscopes, remote controller, acoustic input dephonoprojectoscope, like this, when a plurality of electronic equipments 2 carry out unidirectional single-channel data signal transmission with receiving element 11 simultaneously, cooperate the unlike signal frequency that is comprised in data-signal of each emission, can avoid the situation about can't judge that causes of obscuring by the phase mutual interference of signal transmitting and receiving or signal.
The above only is the method for avoiding transmitting-receiving frequency of electronic equipment interference provided by the present invention and the preferred embodiment of device thereof, be not so promptly limit claim of the present invention, the equivalent structure transformation that every utilization specification of the present invention and accompanying drawing content are done, or directly or indirectly be used in other relevant technical field, all in like manner be included in the claim of the present invention.
