Embodiment
Please with reference to shown in Figure 1, it is the calcspar of the wireless sharing apparatus of first embodiment.Wireless sharing apparatus 100 comprises locating module 110, modem module 120, computing module 130 and wireless transport module 140.Locating module 110 is in order to receiving a satellite-signal, producing one first coordinate information, and the position that promptly wireless sharing apparatus 100 is current.And locating module 110 can be GPS (Global Positioning System, GPS).
In addition; Wireless transport module 140 also can have the communications protocol of international electronic motor engineering association standard; Like IEEE 802.11a, IEEE 802.11b, IEEE 802.11g or IEEE 802.11n etc.; The Wireless Fidelity that promptly generally is commonly called as (Wireless Fidelity is hereinafter to be referred as WIFI) transfer function.
Please with reference to shown in Figure 2, it is the operation chart of the wireless sharing apparatus of second embodiment.Base station 210 as be arranged on far-end and be on the fixing position, so base station 210 itself has had a locating information accurately.In addition, base station 210 also disposes a GPS (GPS) 211, with through with the satellite line after, produce a measurement and positioning information.And base station 210 can be transmitted accurate in locating information and the measurement and positioning information mode with a wireless signal.In the present embodiment, aforesaid accurate in locating information is as being the reference coordinate information of first embodiment, and for example is longitude 55.5 degree, and latitude is 23.5 degree, and representes with Br.Aforesaid measurement and positioning information is as being second coordinate information of first embodiment, and for example is longitude 55.3 degree, latitude 23.7 degree, and represent with Bp.
On the other hand, locating module 110 can receive a satellite-signal, and produces first coordinate information (being the current locating information of wireless sharing apparatus 100) of first embodiment according to this, for example be longitude 20.5 degree, and latitude 60.1 is spent, and representes with Ap.Then, locating module 110 can be sent to computing module 130 with the first coordinate information Ap, just then computing module 130 can be proofreaied and correct (adjustment) first coordinate information Ap, to produce three-dimensional information (as representing with Ar) according to the error amount Δ T that is calculated.For example, the first coordinate information Ap is added error amount Δ T, to produce three-dimensional information A r, i.e. Ap+ Δ T=Ar.Therefore, the three-dimensional information A r that calculating group 130 calculated then is longitude 20.7 degree, latitude 59.9 degree.The wireless sharing apparatus 100 of present embodiment is by similar differential type GPS (Differential Global Positioning System; DGPS) locator meams; Therefore the three-dimensional information A r after calibrated can be more accurate, and the error range of location can be in 1 meter.
Afterwards, three-dimensional information A r can be sent to wireless transport module 140, outwards to transmit (step S410) through wireless transport module 140.At this moment; The Bluetooth function of user's portable electronic devices 220 just capable of using (notebook computer or mobile phone) configuration or WIFI function and wireless transport module 140 match and line; Receiving aforesaid three-dimensional information A r, and learn the position at current place.In addition, but the user only needs in portable electronic devices 220, to install the application program of decipher three-dimensional information, and the function of the electronic chart of arranging in pairs or groups, and can go out the position situation at current place through the screen display of portable electronic devices 220.
Please with reference to shown in Figure 3, it is the operation chart of the wireless device of the 3rd embodiment.Base station 310 can be arranged at far-end and produce the data information in order to surf the Net, and transmits with the mode of wireless signal.And modem module 120 with the communications protocol of its configuration with after base station 310 is connected, can receive and transmit the data information that base station 310 is produced.Suppose that the residing position of user does not have WIFI signal (or do not have and dispose spider lines); Be that the user can't surf the Net through WIFI (or cable network), just WIFI function that user's portable electronic devices capable of using this moment (like notebook computer or mobile phone) 310 sets or Bluetooth function and wireless transport module 140 match and line.Afterwards, the data information that modem module 120 is received can be sent to portable electronic devices 310 through wireless transport module 140, reaches the purpose of online whereby.So, even if the user does not have under the situation of WIFI signal (or cable network), can surf the Net whenever and wherever possible through wireless sharing apparatus 100.
Earlier figures 2 is explained wireless sharing apparatus 100 positioning actions and last net operation respectively with Fig. 3, but is not limited to single operator scheme, and the user also can surf the Net and obtains locating information through wireless sharing apparatus 100 simultaneously.In addition, wireless sharing apparatus 100 can also be supplied a plurality of users simultaneously and use, if promptly different users can match with wireless sharing apparatus 100 and line after, just can surf the Net and obtain current locating information.
By the explanation of aforementioned second embodiment, can summarize a kind of localization method of wireless sharing apparatus.Please with reference to shown in Figure 4, it is the localization method process flow diagram of the wireless sharing apparatus of the 4th embodiment.At first, in step S402, receive a satellite-signal, to produce one first coordinate information.In step S404, receive reference coordinate information and one second coordinate information.Afterwards, in step S406,, obtain an error amount according to the reference coordinate information and second coordinate information.Then, in step S408, utilize error amount to proofread and correct first coordinate information, to obtain a three-dimensional information.At last, in step S410, three-dimensional information is outwards transmitted.So, after portable electronic devices 220 receives three-dimensional information, can make portable electronic devices 220 more accurately locate.
Comprehensively above-mentioned; Wireless sharing apparatus of the present invention can obtain current position exactly by the locator meams like DGPS; Behind user's portable electronic devices just capable of using and wireless transport module (Bluetooth function or the WIFI function) line, to obtain current locating information.On the other hand, the user can carry out the data information transmission through wireless transport module, modem module with portable electronic devices, to surf the Net.Thus, user's function that just can obtain accurate in locating information whenever and wherever possible and surf the Net by wireless sharing apparatus provided by the present invention.
Though the present invention discloses as above with preferred embodiment; Right its is not that any those skilled in the art are not breaking away from the spirit and scope of the present invention in order to qualification the present invention; When can doing a little modification and perfect, so protection scope of the present invention is when being as the criterion with what claims defined.
