Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Referring to Fig. 1, is the function diagram of the electronic installation that can receive the radiofrequency signal with particular frequency range 100 of a preferred embodiments.In the time that reception has the radiofrequency signal of particular frequency range, if the operating frequency of the electronic component in electronic installation 100 is in this particular frequency range, electronic installation 100 can adjust this electronic component operating frequency so that the operating frequency after adjusting not in this particular frequency range, thereby avoid electronic component work time to disturb this to there is the radiofrequency signal of particular frequency range.Electronic installation 100 comprises input unit 110, receiving element 120, acquiring unit 130, detecting unit 140, processing unit 150 and has multiple electronic components such as Double Data Rate synchronous dynamic random internal memory (DDR).Electronic installation 100 is TV in the present embodiment.
Receiving element 120 responds the input signal received RF signal that input unit 110 produces.
Detecting unit 140 is for detecting the operating frequency of electronic component and produce detection signal in the time that the operating frequency of electronic component being in this particular frequency range.
Preferably, the also centre frequency f0 of radiofrequency signal and the operating frequency f of the electronic component detecting for relatively receiving of processing unit 150.If the operating frequency of electronic component is less than the centre frequency f0 of the radiofrequency signal receiving, processing unit 150 is adjusted to operating frequency f in the scope that is less than lower limit, for example, the operating frequency f of electronic component is adjusted to: (f-μ) MHz.If the operating frequency of electronic component is greater than the centre frequency f0 of the radiofrequency signal receiving, processing unit 150 is adjusted to operating frequency f in the scope that is greater than higher limit, for example, the operating frequency f of electronic component is adjusted to: (f+ μ) MHz.
For ease of technical scheme of the present invention is described, receive the radio signals with particular frequency range as example taking television set, the operation principle of electronic installation 100 is described.
For example, in the time that user selects channel (channel for finance and economics S1) by input unit 110, it is the radio signals that channel for finance and economics S1 is relative with this selection channel that receiving element 120 receives.Acquiring unit 130 obtains for example 601MHz～617MHz of particular frequency range F(of the radio signals corresponding with channel for finance and economics S1), wherein, μ=8, f0=609MHz.Detecting unit 140 is detected the operating frequency of electronic component.For example, if detect the such as 604MHz of operating frequency f(of electronic component (DDR)) in this frequency range F, and be less than this centre frequency f0.The operating frequency f that processing unit 150 is adjusted this DDR is (f-μ) MHZ, be 566MHz, so that the operating frequency of this DDR is in this frequency range F, thus while avoiding electronic component work because its operating frequency causes interference in the particular frequency range of received radio signals to it.
Refer to Fig. 2, a kind of radiofrequency signal method of reseptance is for above-mentioned electronic installation 100, and this radiofrequency signal method of reseptance comprises the steps.
Step S210, receiving element 120 responds the radiofrequency signal that user operates to receive.In the present embodiment, the operation that receiving element 120 responds user selected channel is to receive the radio signals corresponding with this selection channel.
Step S220, acquiring unit 130 is according to the particular frequency range F of this radiofrequency signal receiving of radio frequency signal acquisition receiving, wherein, this particular frequency range F has lower limit f1, is greater than the higher limit f2 of lower limit f1 and the centre frequency f0 between lower limit f1 and higher limit f2.
Step S230, detecting unit 140 is detected the operating frequency f of electronic component.
Step S240, whether the operating frequency f of detecting unit 140 electronic component that further judgement detects is in frequency range F, if not, flow process finishes: if so, processing unit 150 is adjusted the operating frequency of electronic component so that the operating frequency of the electronic component after adjusting is not disturbed the received radiofrequency signal with particular frequency range.In the present embodiment, processing unit 150 is by being adjusted to the operating frequency of electronic component not in described particular frequency range, there is the radiofrequency signal of particular frequency range described in not disturbing to realize the operating frequency of electronic component, be specially: first processing unit 150 judges the size (step S250) of operating frequency f and the centre frequency f0 of electronic component, if the operating frequency f of electronic component is less than the centre frequency f0 of the radiofrequency signal receiving, processing unit 150 is adjusted to the operating frequency f of electronic component (step S260) in the scope that is less than lower limit f1; If the operating frequency f of electronic component is greater than the centre frequency f0 of the radiofrequency signal receiving, processing unit 150 is adjusted to the operating frequency f of electronic component (step S270) in the scope that is greater than higher limit.
In sum, although disclose for the purpose of illustration the preferred embodiments of the present invention, but the present invention is not confined to embodiment as above, not exceeding in the category of basic fundamental thought of the present invention, the technical staff of relevant industries can carry out various deformation and application to it.
