It is the guider and the method thereof of display base with the direct of travel that the present invention proposes a kind of, basic composition is as shown in " Figure 1A ", include input block 10, CPU (central processing unit) 12, gps receiver 14, gps antenna 16, display unit 18 and internal memory 20, this is the first embodiment aspect of guider 5.
Guider 5 is mentioned actual when carrying out path navigation in the front, CPU (central processing unit) 12 can carry out the calculating of navigation spots current location according to received a plurality of satellite signals and the counterparty between the course line is that the direct of travel diagram is provided in navigation screen to the pass according to current location and planning, and 5 navigation screen that can provide of guider of the present invention are characterised in that the going direction changing of the navigation spots that its display mode can be judged according to guider 5 and dynamically adjust, particularly at the part of navigation spots display position and navigation map indication range, allow the user can in navigation screen, obtain more route information and other setpoint information, air navigation aid is described as follows shown in " Fig. 2 A " in detail:
At first, CPU (central processing unit) 12 can be set the course line (step 100) that generates between the destination navigation spots with representing guider 5 own according to the destination of user in guider 5; Then after finishing flight course planning, carry out initialization procedure so that the user to be provided result that can the whole flight course planning of overview, and according to the second display parameter show navigator point and the corresponding navigation map (step 110) in navigation screen of first display parameter of predetermined navigation spots and predetermined navigation map; Along with moving of navigation spots, CPU (central processing unit) 12 can continue to carry out path navigation according to satellite signals, and the direct of travel parameter that is produced during according to path navigation to produce corresponding direct of travel in navigation screen graphic, does and the direct of travel of judging navigation spots simultaneously change? (step 120) just dynamically adjusts first display parameter (step 130) of navigation spots according to the direct of travel parameter when the direct of travel parameter change of navigation spots; Dynamically adjust second display parameter (step 140) of navigation map according to first display parameter; At last according to first display parameter and the second display parameter show navigator point and navigation map (step 150) in navigation screen.
First display parameter are the demonstration positional parameters that are used for being set in relevant navigation spots in the navigation screen, generally all are to represent with pixel coordinate position; Second display parameter then are the indication range parameters that is used for being set in relevant navigation map in the navigation screen, generally are to generate corresponding to the navigation map indication range size around the navigation spots with reference to first display parameter.As previously mentioned, all navigation screen all are that navigation spots is positioned over the central authorities of navigation screen and decides the navigation map scope that institute should show around the navigation spots with level and the equal symmetrical manner of vertical direction in known technology, and therefore first display parameter and second display parameter are fixed in the process of entire path navigation and can not changed.But in the present invention, the initialization of being carried out when finishing flight course planning shows that the stage can carry out the demonstration of correlation navigation picture with predetermined first display parameter and second display parameter, go forward side by side in the process that walking along the street directly navigates when navigation spots begins to move, first display parameter and second display parameter then at any time can the changes to some extent because of the going direction changing of navigation spots.
The change of first display parameter and second display parameter, must meet basically " direct of travel parameter and this first display parameter are to present reverse pass to be, this direct of travel parameter and this second display parameter be present forward close be " principle.So-called reverse pass is, expression when the direct of travel parameter be during towards north-westward (promptly towards the navigation screen upper left side), first display parameter must make the demonstration of navigation spots be partial to the southeast in the navigation screen to (promptly towards the navigation screen lower right); And for example when the direct of travel parameter be during towards North-East Bound (promptly towards the navigation screen upper right side), first display parameter then must make southwest in the demonstration deflection navigation screen of navigation spots to (promptly towards the navigation screen lower left).This reverse closing is presenting when showing can also convert the actual pixels coordinate position that reverse pass is middle navigation spots according to the longitude and latitude angle of direct of travel parameter representative to.So-called forward closes, then expression when the direct of travel parameter be during towards north-westward (promptly towards the navigation screen upper left side), second display parameter must strengthen the indication range ratio (promptly towards navigation screen upper left side) of navigation map in the navigation spots north-westward; And for example when the direct of travel parameter be during towards North-East Bound (promptly towards the navigation screen upper right side), second display parameter then must strengthen navigation map in the indication range ratio in navigation spots North-East Bound (promptly towards the navigation screen upper right side).This forward close be can also be converted to presenting when showing around the navigation spots according to the actual displayed position of navigation spots the actual ratio size of all directions navigation map that should show.
Can under the big principle of the technology of the present invention principle, freely set by those who are familiar with this art as for the rule of the conversion correspondence between direct of travel parameter, first display parameter and second display parameter and there is no particular limitations.
About judging the part of direct of travel parameter change, be to close to calculate from the relative direction between the course line that the location and the desire navigation of present navigation spots position are advanced through CPU (central processing unit) 12 to learn basically.In addition, the part of direct of travel parameter change can also directly offer CPU (central processing unit) 12 through the signal of external unit and make judgment processing, please refer to the part of " Figure 1B ", the second embodiment aspect for guider 5 of the present invention, wherein how be that with " Figure 1A " difference a sensing unit 22 is electrically connected at CPU (central processing unit) 12, direct of travel parameter this sensing unit 22 can directly directly provide change when navigation spots generation going direction changing after is to CPU (central processing unit) 12, when CPU (central processing unit) 12 is pointed to the signal of unit 22 once receiving from the outside, can start and carry out the program of dynamically adjusting first display parameter and second display parameter, finish in the navigation screen demonstration of navigation spots and navigation map equally and dynamically adjust.
Corresponding air navigation aid is as shown in " Fig. 2 B ", and the difference between " Fig. 2 A " only is after the demonstration of completing steps 110 initialization navigation screen, the sensing unit 22 that start along with guider 5 this moment begins to calculate the direct of travel of navigation spots, when the front and back direct of travel of a discovery navigation spots changes, just can directly send corresponding direct of travel parameter directly carries out first display parameter and the dynamic program of adjusting (step 160) of second display parameter for CPU (central processing unit) 12, omitted the step 120 of judging going direction changing in original " Fig. 2 A " by CPU (central processing unit) 12, reduce the processing burden of CPU (central processing unit) 12, and the flow process of follow-up processing is all identical with " Fig. 2 A ".
" Fig. 4 A " reaches " Fig. 4 B " for implementing the synoptic diagram of navigation screen of the present invention, can fully show the effect that this case technology contents is produced, and is described as follows:
