Please consult Fig. 2 earlier, the GPS running control system that has external communication in the present embodiment is assembled in (as commercial car, lorry, truck ... wait other motor vehicles) on the vehicle 8.Vehicle 8 has head lamp device 81, fog lamp device 82, more senior recently vehicle also adds to be provided with sound play device 831 (Audio Device), image player 832 (Video Device) ... etc. multimedia system 83 (Multimedia System), and wireless communication apparatus 84 (as portable telephone device) etc.
See also Fig. 3, above-mentioned various automobile-used accessories are connected on the microprocessor 3 via a bus-bar 30 respectively, and other has a GPS global location device 1 and a memory storage 2 also to be connected to bus-bar 30 respectively.And the GPS running control system 10 with external communication can be by wireless communication apparatus 84 and base station 45 contacts, base station 45 can be passed to message control centre's 40 processing in case of necessity, wherein base station 45 normally is used as a group through-connection station, therefore number can much and be dispersed in various places so that receive signal, and technology of the present invention promptly is according to the different position of vehicle 8, and selects a suitable base station 45 to make the quality of communication be improved or the cost of communication is minimized.
See also the implementing procedure figure of Fig. 4 present embodiment again, following flow chart is to carry out and base station contact flow process before when wireless communication apparatus 84, make wireless communication apparatus 84 to get in touch with a suitable base station that is selected, but certainly this flow process also each section period promptly carry out once, for example promptly carried out once this flow process in per ten minutes.
Step 401:
Obtain the position coordinates of present vehicle 8.The GPS global location device 1 of present embodiment receives three HA Global Positioning Satellite 91 in the space with its gps antenna 11 earlier, 92,93 signal (Fig. 2), and calculated out vehicle 8 global location data at that time with its microprocessor 12, it can include the longitude and latitude position, that is the position coordinates of vehicle 8.
Step 402:
Seek out the contact information 23 that should get in touch with base station by the position coordinates of vehicle 8.The mode of finishing this step is a lot, is basically to utilize the position coordinates of vehicle 8 to be as the criterion to find nearest base station.But nearest sometimes base station is not the most appropriate base station, be example for example with the U.S., though vehicle 8 is in the New Jersey, but apart from vehicle 8 nearest base stations is a base station of New York, if wireless communication apparatus 84 is a portable telephone device, then must get in touch with the base station that is positioned at the New Jersey, so that save communication fee.
The embodiment of treatment step 402 of the present invention is described in step 501～503rd, below please be earlier in the lump with reference to figure 5, and Fig. 7 and Fig. 8.
Fig. 5 is first embodiment of the present invention about base station inquiry data bank 20.Base station inquiry data bank 20 includes the field of main rectangular coordinates 21, the field of inferior rectangular coordinates 22, the field in the field of base station contact information 23 and zone 24.
Fig. 7 shows three zones, regional A, and area B and zone C, and there is base station 45a, base station 45b, a base station 45c who is responsible in each zone.Each zone is contained by a main rectangle, is respectively main rectangle RA, main rectangle RB, main rectangle RC.The position information of each main rectangle comprises the clinodiagonal two positions coordinate of rectangle.With regional A is example, and main rectangle RA is in order to describing the scope of regional A, main rectangle RA then with coordinate (Xa1, Ya1) and (Xa2 Ya2) defines.Therefore the field of main rectangular coordinates 21 promptly is the clinodiagonal two positions coordinate of the main rectangle of record.
Yet it is not enough that a zone is described with a main rectangle, for example vehicle 8 is at position P1, and position P1 is contained by main rectangle RA and main rectangle RC, so still must judge position P1 is within the rectangle RA or within main rectangle RC, and the scope that main rectangle RA and main rectangle RC are contained jointly is too wide, therefore if only judge from main rectangle, its misjudgment number of times is necessarily very frequent so can't be accepted.
Fig. 8 is the schematic diagram that the following rectangle of demonstration is described position first embodiment in a zone.
With regional A is example, more describes regional A with a plurality of rectangles, inferior as shown in the figure rectangle RA-1, inferior rectangle RA-2, inferior rectangle RA-3 or the like.Similarly the position information of rectangle comprises the clinodiagonal two positions coordinate of rectangle each time.In proper order rectangle RA-1 is an example, inferior rectangle RA-1 with coordinate (Xa11, Ya11) and (Xa21 Ya21) defines.Because of the field of this time rectangular coordinates 22 promptly is the record time clinodiagonal two positions coordinate of rectangle.
And base station contact information 23 is the telephone number of record base station in the present embodiment.Step 501:
Which main rectangle the position coordinates that utilizes base station inquiry data bank 20 to find out present vehicle 8 falls within.
Step 502:
Does the position coordinates of vehicle 8 fall within main rectangle and whether surpasses more than one main rectangle? if then need proceed step 503.
For example the position coordinates of vehicle 8 is contained by main rectangle RA and main rectangle RC at position P1, therefore need proceed step 503.But,, therefore need not proceed step 503 so can confirm vehicle 8 in regional A if the position coordinates of vehicle 8 has only main rectangle RA to contain at position P2.
Step 503:
Which continue to the inferior rectangle in the zone that searches out to seek to fall within main rectangle to be confirmed to be.For example the position coordinates of vehicle 8 then arrives first a certain zone and seeks the inferior rectangle that whether falls within wherein, that is seek to the field of time rectangular coordinates 22 at position P1, so then can determine to be arranged in which zone.If certainly inferior rectangle is more little then accuracy is high more on the border in a zone, but to calculate and stored data cost high more.
Step 403:
The base station of getting in touch with is set at the base station that finds, that is the base station contact information that will get in touch with is set to find and is responsible for this regional base station contact information.
By the base station that step 402 found, such as therefore the position coordinates of vehicle 8 is responsible for by the base station of regional A, so base station contact information 23 is " 818-12345678 " at position P1.
Above embodiment can have other many variations, states clearly as follows:
Fig. 6 is second embodiment of the present invention about base station inquiry data bank 20.In this embodiment, the not main rectangular coordinates 21 of base station inquiry data bank 20, the position of therefore directly comparing vehicle 8 is to be positioned within which time rectangular coordinates 22 promptly know it is to fall within which zone, this kind searching mode is more time-consuming certainly.
Fig. 9 is the schematic diagram that the following rectangle of demonstration is described position second embodiment in a zone.The size of rectangle (dotted line is represented) is identical each time, and advantage is to utilize computer to produce rectangle each time easily, but because time rectangle number can be more, and is therefore more time-consuming when doing time rectangle and seek.Certainly also can develop an algorithm, the inferior rectangle of the identical size of Jiang Geyuan merges, and forms the inferior rectangular embodiment less as Fig. 8 number.
In sum; no matter the present invention all shows it totally different in the feature of prior art with regard to purpose, means and effect, and above-mentioned many embodiment only give an example for convenience of explanation; but not only limiting to the foregoing description, the protection range that the present invention advocated should be as the criterion so that claims are described.
