The utility model can measure the signal strength of an individual channel to reinforce and adjust the communication quality of channels when a wireless system is erected, and the utility model can also measure communication range to obtain the maximum utilization rate of the channels and to ensure the communication quality when the wireless system is used.
Description
Technical field
The utility model is a kind of microwave signal detector, it can predict the signal power of individual channels (channel), strengthened, adjusted the communication quality of each channel when providing wireless system to set up, and can be by measuring communication context, with the purpose that when using wireless system, reaches the peak use rate of each channel and guarantee communication quality.
Background technology
Because there is the bright scope of ordering the wireless telecommunications frequency in national governments, mostly needs to apply for a license and to use at present.And in open frequency of giving the public purpose scope such as industry, science, medical science, then need not license can use for popular.The scope that various countries generally open is neither to the greatest extent identical, and general various countries are mostly with (the Federal Communications Committee of US Federal Communication Committee; FCC) standard is that blueprint is worked out range of opening.According to (the FederalCommunications Committee of US Federal Communication Committee; FCC) revision version of being announced October 1 calendar year 2001, open frequency range to public purpose is three frequency bands (band) such as 902～928MHz, 2400～2483.5MHz, 5725～5850MHz, this is general so-called industry, science, medical band (Industrial, Scientic and Medical band; ISM band).
Though yet various countries are mostly with (the FederalCommunications Committee of US Federal Communication Committee; FCC) standard of Gong Buing is that blueprint is worked out range of opening, but still has different part, and this difference part slightly, has become a difficult problem incompatible in the communication.The frequency band (band) of lifting 2.4～2.5GHz is an example: the section of the U.S., Canada and Central and South America is that the partly national section in 2400～2483.5MHz, Europe is that 2400～2483.5MHz, French section are that 2446.5～2483.5MHz, Japan but have only domestic part zone can use the section of 2471～2497MHz.
Because the open frequency range of public purpose of giving in various countries is fixed different, then when a user by France to Germany or by Japan to Europe, face immediately can't communication problem.Therefore lost and formulated industry, science, medical band (Industrial, Scientic and Medical band originally; ISM band) give public masses (public) kindness easily, when therefore having fermented some and being to solve cross-region, the solution of the different communication difficulties that cause of frequency band each other.
The U.S. Patent No. 5867766 of Dinc et al. discloses a technology, and this technology is to be used for a wireless communication apparatus, and this technology makes this wireless communication apparatus receiving terminal can search all available channels automatically and switching mutually between channel when communication.When communication,, then can search an available channel automatically and switch to this channel if the channel energy in using is crossed low or too noisy.At transmitting terminal, then can use the channel and the receiving terminal communication of this ground standard according to the employed channel of local standard.
The U.S. Patent No. 6556825 of Carl Mansfield mentions that one installs the setting that can survey and change this device according to different regions, place automatically, need not additionally manually to go to set and adjustment, so that be in the transmitting terminal and the receiving terminal communication all smoothly of different regions.
Right above-mentioned solution is conceived to the improvement of communication problem between different regions, for the less inking of the quality of communication.This solution also can't be surveyed RF (RadioFrequency) the signal power of each channel (channel), can only survey RF (Radio Frequency) signal of a certain frequency band (band) and the gross energy of all channels, can't predict the energy of individual channels (channel), the lifting of communication quality be there is no benefit thus.
Please refer to Fig. 1, the structural system figure of prior art signal sensor.This signal sensor comprises that an antenna 11, a band filter (Band Filter) 12, one local oscillator (LocalOscillator) 13, receive conversion sorting circuit (DC Calibration) 14, one analog-to-digital conversion circuit (Analog/Digital Converter) 15, one microprocessor (Microprocessor) 16, a light-emitting diode (Light Emitting Diode; LED) 17.
After one antenna 11 receives a microwave, take out needed frequency band (band) by a band filter (Band Filter) 12.The frequency that one local oscillator (Local Oscillator) 13 control will be taken out this frequency band (band) is for channel frequency accurately.After frequency was determined, one receives conversion sorting circuit (DC Calibration) 14 can take out into analog signal with signal, and analog signal is reached an analog-to-digital conversion circuit (Analog/Digital Converter) 15.This analog-to-digital conversion circuit (Analog/Digital Converter) 15 will receive conversion sorting circuit (DC Calibration) 14 analog signal conversion that send and become digital signal, to make things convenient for subsequent treatment.One microprocessor (Microprocessor) 16 handles the digital signal of analog-to-digital conversion circuit (Analog/Digital Converter) 15 outputs.
Microprocessor (Microprocessor) 16 can export the consequential signal of computing to light-emitting diode (Light Emitting Diode when computing; LED) 17, so that allow the user understand result of detection output.
The signal sensor of the prior art can't conversion for fixed frequency because of local oscillator (Local Oscillator), only can record the gross energy of all channels, and can't record the energy of each channel, so the behaviour in service that the user can't be by understanding each channel and and then make full use of, therefore, the structure of the signal sensor of the prior art gives improved necessity in fact.
