Description
Technical field
The present invention relates to a kind of navigation software technology, be specifically related to a kind of dynamic Campus Navigation System in real time.
Background technology
In recent years, along with the expansion gradually of university campus and the increasing of foreign exchanges, the people going to colleges and universities to visit also got more and more, the new life of campus of particularly just having entered into, often worried because being unfamiliar with landform.The floor area of colleges and universities is general all very large, and seldom has school can provide paper map to newborn, brings certain puzzlement to so a lot of people.Along with the generally utilization of smart mobile phone, a lot of people wishes a simple wieldy campus navigation software.
Also there is some software navigated for campus at present, some are had to be directly plan route based on map software such as Baidu's maps, but this kind of software based on the road of map to campus be not very applicable, such as, the road in campus is mostly all smaller and some is more hidden, uses this kind of software can not navigate to the place to go wanted exactly; Although there are some softwares to possess oneself independently map data base, the problem of campus road can be solved, but the road that its navigation still directly provides based on a system navigates, sometimes mistake may fall some chances of taking a short cut, the distance of finally navigating does not realize minimum distance in fact.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides the dynamic in real time Campus Navigation System that a kind of body can realize minimum distance navigation.
In order to achieve the above object, technical scheme of the present invention is as follows:
Dynamic Campus Navigation System in real time, it comprises:
Position acquisition module, for the current location of user in real, generates multiple real time position data simultaneously;
Data processing module, database module is provided with in it, each information of bar road and the summit of road is stored in this database module, this data processing module first pulls out straight line by between starting point and terminal, and using the direction of straight line indication as direct of travel, this data processing module finds out the nearest road of a distance starting point according to direct of travel from database module, and determine that its summit is as the first summit, this data processing module constantly obtains real time position data from position acquisition module, when the location point that real time position data comprises coincides with the first summit, this data processing module finds out the nearest road in distance first summit according to direct of travel again from database module, and determine that its summit is as the second summit, this data processing module constantly obtains real time position data again from position acquisition module, when the location point that real time position data comprises coincides with the second summit, this data processing module finds out the nearest road in distance second summit according to direct of travel again from database module, with this, the rest may be inferred, until the summit of the location point that comprises of real time position data that obtains of the data processing module road nearest apart from terminal with the last item overlaps, navigation terminates.
The present invention by pulling open straight line between starting point and terminal, and with this straight line determination terminal direction, then data processing module is again to the continuous contrast of link vertex and location point, and then in database module, the road of minimum distance is constantly found according to direct of travel, through a processing procedure repeatedly, finally reach the summit from the nearest road of terminal, navigation terminates, thus form a complexity and accurate navigation procedure, make finally to obtain navigation distance compared to the navigation of traditional single line, levels of precision and navigation distance are obtained for optimization.
Therefore, compared with prior art, navigation distance can contract nearer by it in the present invention, and also obtains raising on the levels of precision of navigation.
On the basis of technique scheme, the present invention can also do following improvement:
As preferred scheme, above-mentioned position acquisition module is GPS module, WIFI module or signal base station.
Adopt above-mentioned preferred scheme, the levels of precision that positional information is gathered can be improved.
As preferred scheme, be also provided with map and select module in above-mentioned data processing module, map selects module to be classified according to setting classification by the map datum in database module, and according to classification, user enters in different map datum plates.
Adopt above-mentioned preferred scheme, user can be made to select different map plates, such as impart knowledge to students block, dormitory block etc., thus improve the convenience of manipulation.
As preferred scheme, above-mentioned position acquisition module is Network Based and carried out the current location of user in real by the mobile phone of user or other mobile terminals.
Adopt above-mentioned preferred scheme, more quickly and reliably can obtain the positional information of user.
