Abstract
The present invention discloses a method for automatically updating electronic traffic map and its used system. Said invented method and its system can utilize GPS vehicle-mounted location system to automatically implement updating of electronic traffic map so as to promptly trace the traffic line with dynamic change and update the original electronic traffic map without delay.
Description
The present invention relates to a kind of be used for upgrading the automatically method of electronic communication map and used system thereof.
Electronic map system is the software systems of storage and management map in the computing machine.Usually, a map can be broken down into a plurality of figure layers earlier according to content, for example highway layer, railway layer, river layer, buildings layer.In each layer, usually show the element of general map again with the unit in the computing machine map system, present electronic chart element, not outer is point (or symbol), line, zone and four kinds of literal.Point (or symbol) is used for representing the information in place on the map, and for example market, school, bus station etc. in map system, are put and had only position and expression and so on notion, do not have size; Line is used to represent cutting apart of zone, and the river different kinds of roads and large scale under shows as one group of line between the coordinate points, and line has length and represents the notion of what line, does not have width; The zone is used for representing school, buildings of area and small scale map etc., and there is the notion of position and area in the zone.The attribute of map element is divided into two parts, and the one, geographical attribute, i.e. position, length, size, area; Map element is represented the part of what content, as the attribute data of map object.
The various elements of electronic chart by manually or automatically from aerial photograph, original map, by describing, scanning, are drawn in computer system, and are correspondingly imported the information data of the represented content of various map objects.The information retrieval, inquiry, decision-making that can be advantageously used in all trades and professions at electronic chart are used, can the safeguarding easily, upgrade by database of attribute data.The electronic chart of this mode generates, and clearly is divided into the wright of map and the user of map.Usually, a map generalization electronically will be passed through following process:
(1) takes photo by plane and the ground survey, obtain actual landform, relief data;
(2) splicing the many parts of data of taking photo by plane and coming, according to coordinate setting, is stitched together;
(3) layering according to landform, geomorphic type, is analyzed data and is decomposed by level;
(4) digitizing is retouched active data in the computing machine with digitizer, or directly scanning, carries out vector quantization and makes amendment by computing machine;
(5) information labeling is for map object adds satellite information;
(6) issue is chosen a part of level and map object and is packed, and issues to applying unit.
This map generative process is characterized in:
The new map of each part all starts anew, though also can make amendment to original electronic chart, what is revised still needs a large amount of manual interventions.
Map is based on that the needs of map publisher set out, and does not embody user's demand.
In real life, the object on the map, except attribute data be constantly change, map object itself is also in continuous variation, present map is published, and also comprises electronic chart, does not catch up with actual variation far away.Especially in traffic, pipe network field, the variation of road, the setting at crossing, conventional map system is used in the change of single-double direction, can't embody these requirements.Simultaneously, aspect these, Route Length can not embody the time or the flow that need spend by this section circuit in traffic, pipe network, the selection of route can not be only with the far and near form the basis of distance.
The object of the present invention is to provide a kind of method of automatic renewal electronic communication map and used system thereof, it is by means of the GPS vehicle positioning system, automatically finish renewal and modification to the electronic communication map, thereby can in time the traffic route of dynamic change be followed the tracks of and original electronic communication map be dynamically updated, this method and system can also significantly reduce the needs to manual intervention simultaneously, and can embody map user's wish better.
The method of the said automatic renewal electronic communication map of the present invention, it comprises the following steps:
(1) road on the electronic communication map is classified by its usage frequency;
(2) utilize the vehicle GPS/gsm module be loaded on vehicle or other MOVING STRUCTURE in the way of travelling, to receive positioning signal at any time, and calculate automobile present located positional information from position location satellite;
(3) regularly the label information of this vehicle and positional information are sent to map center through the GSM network by the GSP/GSM module;
(4) press the motion track of the every chassis of vehicle registration, and be stored in the database of map center;
(5) road in vehicle motion track and the original traffic map is compared, seek the road that is complementary,, then increase the usage frequency record of this road if the road of coupling is arranged; If no, then on map, newly draw a road, as the road of new picture;
(6) regularly all roads are carried out frequency analysis, and the existing map datum in the map data base is analyzed, compared, reject outmoded content and in time increase the content of upgrading, finish renewal thus the electronic communication map.
The said automatic renewal electronic communication map system of the present invention comprises vehicle GPS/gsm module, map center Data Receiving and molded tissue block and management map and analysis module, wherein:
Said vehicle GPS/gsm module, comprise the GPS localization part and the gsm communication part that are installed on vehicle or other MOVING STRUCTUREs, be responsible for to receive the GPS position location satellite signal, calculate MOVING STRUCTURE present located position and regularly through the gsm communication parts by the GSM network, with the form of short message SMS locating information is sent to map center;
Said map center Data Receiving and molded tissue block, by the special line of setting up with GSM Network Provider, receive and analyze locating information, and be locating information unit by MOVING STRUCTURE, be stored in the database of map center from vehicle-mounted GPS/GSM module on the MOVING STRUCTURE;
Said management map and analysis module will be analyzed, compare the existing map datum in the map data base by the data that obtain in Data Receiving and the molded tissue block, reject outmoded content and in time increase the content of upgrading.
