Abstract
The invention relates to a method for realizing UBox high-speed wireless transmission of a data acquisition device. The data acquisition device comprises a UHF (Ultra High Frequency) transmitting end and a UHF receiving end. A local oscillator is arranged inside the data acquisition device. The frequency of the data acquisition device is in the range of 2.5GHz to 100MHz. At the UHF transmitting end, the method comprises the following steps that the data acquisition device receives a WIFI (Wireless Fidelity) signal; a phaselocked loop circuit inside the data acquisition device subtracts a received frequency of 2.4GHz from a frequency of the local oscillator so as to covert the wave band of the frequency into a UHF waveband; and a converted UHF signal is sent by an antenna of the data acquisition device. At the UHF receiving end, the method comprises the following steps that the data acquisition device receives the UHF signal; and the phaselocked loop circuit inside the data acquisition device adds a frequency of the UHF signal and the frequency of the local oscillator so as to convert the frequency into 2.4GHz. The data acquisition device has high penetration power and a large covering range, is difficult to interfere and can realize a large transmission range under very low frequency.
Description
Technical field
The present invention relates to data acquisition unit (hereinafter to be referred as " UBox "), particularly a kind of based on the method for 802.11 wireless protocols realization UBox in the transmission of UHF wave band high-speed radio.
Background technology
UBox is for the network of providing concatenation ability is provided the USB peripheral hardware, and need not to rely on special-purpose PC is shareable device.It can go to Ethernet with signal, thereby has eliminated the restriction of USB technology to cable length.In case with the equipment access network, UBox just can make any PC that peripheral hardware is carried out access independent or that share.So, be organized in the network environment and also can use the USB peripheral hardware, increased business opportunity greatly.
But present UBox is widely used is the 2.4GHz channel, be based on the wireless signal of 802.11 wireless protocols, but the WIFI signal of present WLAN WLAN commercial product under the power of 10 milliwatts in the indoor scope that can only cover 20 meters, therefore coverage is little, and disturbed easily, confidentiality is poor.
The U section (430.00～440.00MHz), belong to hyperfrequency (Ultra High Frequency is called for short UHF) frequency range, direct wave is propagated better, and U section penetration power is stronger, can realize very big transmission range under very little power.Therefore, the present invention just is based on 802.11 wireless protocols and is down-converted to that uhf band uses.
Summary of the invention
The objective of the invention is to be to solve the shortcoming of prior art, provide a kind of and realize the method for UBox in the transmission of UHF wave band high-speed radio based on 802.11 wireless protocols.
Technical scheme of the present invention: a kind of method that realizes the transmission of data acquisition unit UBox high-speed radio, described data acquisition unit UBox comprises UHF transmitting terminal and UHF receiving terminal, and its inside is provided with a local oscillator, and its frequency is 2.5G-100MHZ;
Comprise at the UHF transmitting terminal:
Described data acquisition unit UBox receives the WIFI signal, its inner phase-locked loop circuit subtracts each other the 2.4GHZ frequency that receives and the frequency of local oscillator, to be the UHF wave band with the frequency frequency conversion, the UHF signal after the conversion is sent by the antenna of described data acquisition unit UBox;
Comprise at the UHF receiving terminal:
Described data acquisition unit UBox receives the UHF signal, and its inner phase-locked loop circuit is the frequency of the UHF signal that receives and the frequency addition of local oscillator, being 2.4GHZ with the frequency frequency conversion.
Among the present invention, described data acquisition unit UBox is based under 802.11 wireless protocols by uhf band and carries out wireless transmission.
Among the present invention, the speed of described wireless transmission is 1Mbps-600Mbps.
The beneficial effect that the present invention has: adopt the method for realization UBox of the present invention in the transmission of UHF wave band high-speed radio, have penetration power and coverage preferably, be difficult for disturbed, can under very little power, realize very big transmission range, and adopt monitor function and dynamic frequency change technique, have extraordinary confidentiality.

Step S3, the UHF signal after the conversion is sent by the antenna of data acquisition unit UBox.
Carry out following steps at the UHF receiving terminal:
Step S4, data acquisition unit UBox receives the UHF signal.
Step S5, the inner phase-locked loop circuit of data acquisition unit UBox be the frequency of the UHF signal that receives and the frequency addition of local oscillator, being 2.4GHZ with the frequency frequency conversion.
Data acquisition unit UBox of the present invention is based under 802.11 wireless protocols by uhf band and carries out wireless transmission, and this wireless transmission rate is 1Mbps-600Mbps.
Data acquisition unit UBox of the present invention is converted to the U frequency range, its coverage can improve 5 times, have penetration power and coverage preferably, be difficult for disturbed, can under very little power, realize very big transmission range, and adopt monitor function and dynamic frequency change technique, have extraordinary confidentiality.
And be applicable to that mega-exhibition, international fair high-speed radio insert, family wireless amusement and various occasions such as colliery, prison and high-risk operation field.
In sum, it only is preferred embodiment of the present invention, be not to be used for limiting scope of the invention process, all equalizations of doing according to the described shape of claim scope of the present invention, structure, feature and spirit change and modify, and all should be included in the claim scope of the present invention.
