Specific embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with this hair Accompanying drawing in bright embodiment, is clearly and completely described to the technical scheme in the embodiment of the present invention, Obviously, described embodiment is a part of embodiment of the invention, rather than whole embodiments.It is based on Embodiment in the present invention, those of ordinary skill in the art are obtained under the premise of creative work is not made The all other embodiment for obtaining, belongs to the scope of protection of the invention.
Typical navigation terminal including special navigator, smart mobile phone, panel computer etc., in order to realize leading Boat function, navigation terminal at least needs to include navigation module, display screen, for storing map data base Memory.Wherein navigation module is included but is not limited to based on GPS, GLONASS (GLONASS), gal The navigation module of the profit slightly navigation system such as (Galileo), the Big Dipper, can at least be obtained by navigation module The longitude and latitude degrees of data of navigation terminal position.By the location information synchronizing of navigation module acquisition to map number According in storehouse, you can obtain position of the navigation terminal on map, it is possible to be shown to user by display screen, So as to realize basic positioning or navigation feature.Further, navigation terminal can also include voice broadcast Function, can also have communication module, navigated or updated using communication network assisting navigation module and deposited Map data base in reservoir.
Because the longitude and latitude degrees of data that the user using navigation terminal cannot be obtained by navigation module determines specifically Position is navigated, but can only be determined by position of the location data in display screen map specific The accuracy of map datum directly affects navigation or the degree of accuracy of positioning in position, therefore navigation terminal.For Ensure the accuracy of map datum, the map datum in each navigation terminal is all by soft in navigation terminal Part developer provide and carry out updating maintenance, user can only obtain navigation map number from software developer It is updated according to and to map datum in navigation terminal.Software developer stores in service map datum In device, user can by the network access server, and from the server downloading map data with more Map datum in new navigation terminal, the server is properly termed as map rejuvenation server.Software developer The data in map rejuvenation server need to be only safeguarded, when cartographic information changes, map rejuvenation is updated Map datum in server, then user may be selected to the map datum in navigation terminal when needed Be updated, or after data during software developer have updated map rejuvenation server, can to Family sends a notification message, and notifies that user carries out the renewal of map datum.Map rejuvenation server is typically set Beyond the clouds, navigation terminal is connected to during internet can obtain map rejuvenation server by any mode Map datum.
But the map datum in map rejuvenation server can only be updated by software developer, and software The approach that developer obtains map datum is limited, causes the update cycle of map datum more long.So user Navigation terminal in the map data update cycle it is equally also more long, in may so causing navigation terminal Map is inconsistent with actual road conditions, and influence user uses.
Fig. 1 is the flow chart of map updating method embodiment one provided in an embodiment of the present invention, such as Fig. 1 institutes Show, the method for the present embodiment includes:
Step S101, terminal device uses navigation module record path information.
Specifically, the terminal device in the present embodiment is the terminal device with navigation module, can be by it Referred to as navigation module.At least include being based on a kind of navigation module of standard in terminal device, led by this Model plane block can determine the geographic position data of terminal device, generally longitude and latitude degrees of data, work as terminal device When moving, navigation module is linked together in the geographic position data that different time is obtained, It is the routing information of the terminal device.That is, the routing information of terminal device is terminal device one The set of geographic position data in section of fixing time, the movement of terminal device can be known by the routing information Path.
Usually, user is mainly and is navigated using navigation terminal in operating motor vehicles, and user is beating When opening navigation terminal, when vehicle starts movement, then can see representative certainly on the display screen of navigation terminal Oneself icon is moved in map, and the track of icon movement is the routing information of navigation terminal in navigation Expression on map.
Step S102, terminal device is to map rejuvenation server transmitting path information, so that map rejuvenation takes Business device is updated using the routing information to the map data base in map rejuvenation server.
Specifically, after it have recorded routing information, can be sent to map rejuvenation server should for terminal device Routing information.With the development of mobile communication technology, mobile terminal can access network whenever and wherever possible, that Using mobile terminal as navigation terminal, it is also possible to access map rejuvenation server anywhere or anytime;Separately Outward, with the development of car networking technology, the energy that special automatic navigator also will progressively possess access network Power, then automatic navigator equally can at any time access map rejuvenation server.Therefore navigation terminal is recorded Routing information can be sent to map rejuvenation server when required by any one mode.
Terminal device can at any time to map rejuvenation server transmitting path information, that is, with map rejuvenation Server remains connection, and map rejuvenation server can at any time obtain the routing information of terminal device. It is contemplated that navigation terminal is large number of, all navigation terminals all keep connecting with map rejuvenation server Connect, the pressure of map rejuvenation server is huge, and it is huge to the pressure of network, simultaneously because navigation is eventually End access network typically can all have corresponding rate, remain that the rate that connection is produced can also bring to user Certain pressure.Therefore can also be using terminal device periodically to map rejuvenation server transmitting path information Mode transmitting path information.
It is general in terminal device that all there is memory, terminal device can be passed through navigation module in memory The routing information of record is temporarily stored in down, and terminal device at regular intervals, or can run up to necessarily After the data of data volume, then to map rejuvenation server transmitting path information.For example terminal device can be with every The routing information for once recording was sent to map rejuvenation server every 10 minutes.Or terminal device can be When opening navigation software every time or when navigation software is closed every time one is sent to map rejuvenation server The routing information of secondary record.Or terminal device can be when temporary routing information data volume reaches 1Mb The routing information for once recording is sent to map rejuvenation server.Terminal device can so be reduced to map Server transmitting path information is updated to map rejuvenation server and the pressure of network, while number can be reduced According to flow, the cost of user is saved.
After map rejuvenation server receives the routing information of terminal device transmission, the path can be believed Cease and contrasted with the map datum stored in map rejuvenation server.If map rejuvenation server finds to connect When the routing information for receiving is inconsistent with the map datum of storage, it is believed that actual road conditions may become Change, it is possible to use the routing information for receiving replaces corresponding path in the map datum for storing.It is now Complete the map rejuvenation of map rejuvenation server.
Further, because single terminal end equipment may be led due to factors such as equipment fault, artificial origins Cause transmission to the routing information of map rejuvenation server is not true road conditions.Such as terminal device may be by There is position error in the reasons such as dtr signal are received;Or terminal device is not moved but used with vehicle Family is hand-held, and the path for causing terminal device records is not road that vehicle can be travelled etc..When in appearance When stating situation, map rejuvenation server goes to update map according only to the routing information that a terminal device sends Update the map datum stored in server, it would be possible to mistake occur.Therefore, map rejuvenation server can After being compared with the map datum of storage with the routing information that will be received, the map datum with storage is differed The path information storage of cause is got up, and records the mark of the terminal device of the routing information for sending each storage Know.When in the routing information of storage, the corresponding different terminal equipment of identical routing information reaches default threshold During value, corresponding path in the map datum of storage is just replaced using the routing information.Believe in identical path Ceasing corresponding different terminal equipment and reaching predetermined threshold value means that the terminal device for having more than predetermined threshold value is all remembered The path was recorded, when the quantity of terminal device is bigger, the path is higher with the matching degree of actual road conditions. Usually, in order to ensure the accuracy of map datum stored in map rejuvenation server, the threshold value can be with What is set is higher, and such as 100 or even more than 1000.
Further, in order to ensure the map Exact Travelling in map rejuvenation server, when map rejuvenation service When device finds the routing information for receiving and the inconsistent map datum for storing, measurement of correlation can also be notified Personnel go to the place to carry out field survey.Because navigation terminal is carried by user, and user differs Navigation terminal can be used in vehicle calmly, therefore the path of navigation terminal record may not be actual road Road.So in order to ensure the accuracy of map in map rejuvenation server, or by the exploitation of navigation software Person carries out the accuracy that field survey more ensure that map to road.But the side provided using the present embodiment Method, can make road survey personnel be accurately positioned the place for needing to carry out field survey, and without to all Place all measures, and can so save measurement cost.
Step S103, terminal device receives the map rejuvenation notification message that map rejuvenation server sends, ground Figure update notification message includes the information being updated to routing information.
Specifically, when map rejuvenation server have updated storage according to the routing information that terminal device sends After map datum, in order that the map in terminal device is also consistent with actual road conditions, terminal device will be received To the map rejuvenation notification message that map rejuvenation server sends, it is right that the map rejuvenation notification message includes The information that routing information is updated.Wherein, the routing information that the map rejuvenation notification message includes is The fresh information in the path that map rejuvenation server is updated.The information that this pair of routing information is updated The routing information that terminal device sends to map rejuvenation server is not limited to, map rejuvenation server is according to it After the routing information that his terminal device sends is updated to the map datum in map rejuvenation server, Also the update notification message on the routing information will be sent.In a word, when map rejuvenation server update After the map datum of its storage, it is possible to send update notification message to terminal device, that is, terminal sets The standby map rejuvenation notification message that may at any time receive the transmission of map rejuvenation server.And due to map more New demand servicing device frequently sends map rejuvenation notification message and can consume substantial amounts of data traffic to terminal device, together When can also increase the pressure of map rejuvenation server, therefore map rejuvenation server can also periodically to Terminal device sends update notification message, and terminal device receives map rejuvenation server and sends out with a predetermined period The map rejuvenation notification message for sending.Or map rejuvenation server is it is determined that terminal device access network Shi Caixiang terminal devices send map rejuvenation notification message, further, can also be it is determined that terminal device It is when being accessed by WiFi network, just to send map rejuvenation notification message to terminal device, can be further Save the data traffic of terminal device in ground.Or map rejuvenation server can receive terminal device hair Just map rejuvenation notification message is sent after the renewal request message sent to terminal device.
Step S104, terminal device is using the routing information in map rejuvenation notification message in terminal device Map data base be updated.
Specifically, after terminal device receives the map rejuvenation notification message of map rejuvenation server transmission, The routing information in the map rejuvenation message can be used to be carried out more to the map data base in terminal device Newly.Specific update method is identical with the update method in map rejuvenation server, that is, use what is received Routing information in map rejuvenation notification message replaces same place in the map datum stored in terminal device Path.So that the ground stored in the map datum stored in terminal device and map rejuvenation server Diagram data is consistent.
Because the map datum in map rejuvenation server is that the routing information sent according to terminal device is carried out Update, and terminal device can send the routing information of record to map rejuvenation server at any time so that The data stored in map rejuvenation server ensure that real-time update, so as to shorten map rejuvenation service The update cycle of map datum in device, namely the update cycle of map datum in terminal device is shortened, There is provided after the rational transmission cycle, can ensure that the map in terminal device keeps with actual road conditions substantially Unanimously, improve the precision that user's using terminal equipment is navigated.
Map updating method provided in an embodiment of the present invention, the road that terminal device is recorded using navigation module Footpath information is sent to map rejuvenation server, make map rejuvenation server using the routing information to map more Map data base in new demand servicing device is updated, and then terminal device receives map rejuvenation server hair again The map rejuvenation notification message for sending, and using the routing information in map rejuvenation notification message to terminal device In map data base be updated, realize automatically updating for navigation map, and shorten renewal week Phase, improve the precision that user's using terminal equipment is navigated.
Further, in the embodiment shown in fig. 1, terminal device will be to map rejuvenation in step s 102 Server sends all routing informations that recorded, and terminal device is not at the routing information that records Reason.But terminal device can consume many numbers to all routing informations that map rejuvenation server sends record According to flow, one to increase the expenses of surfing Internet of user, and two that also huge pressure can be carried out to Netowrk tape.Cause This, in the embodiment shown in fig. 1 the step of S102 before, can also comprise the following steps:Terminal device Routing information is contrasted with the map data base of storage in terminal device.So terminal device is to map Server transmitting path information is updated, including:When the map datum stored in routing information and terminal device When storehouse is inconsistent, terminal device is to map rejuvenation server transmitting path update notification message, routing update Notification message includes routing information, so that map rejuvenation server uses routing information to map rejuvenation service Map data base in device is updated.
That is, terminal device is after it have recorded routing information, can first by routing information and terminal The map datum stored in equipment is contrasted.Because the map datum stored in terminal device is from map Obtained in renewal server, if the map rejuvenation between map rejuvenation server and terminal device is in time, Then it is considered that the map datum of storage is identical in both.Therefore terminal device can to map more Before new demand servicing device transmitting path information, first routing information is judged, that is, should be by map The treatment that updating server is carried out is carried out in being placed on terminal device.When terminal device judges the path letter of record When breath is inconsistent with the map data base of storage in terminal device, then terminal device is just to map rejuvenation service Device transmitting path update notification message, the routing update notification message includes above-mentioned inconsistent routing information. And when terminal device records routing information with terminal device store it is consistent when, then terminal device will not The routing information is sent to map rejuvenation server.Sent when map rejuvenation server receives terminal device Routing information after, it can again be judged, it is also possible to no longer judged.Due to leading at present The service of boat map is more ripe, and map will not typically be changed on a large scale in a short time, therefore So terminal device only record routing information with storage routing information it is inconsistent when just to map rejuvenation Server send the routing information, it is necessary to send data volume will greatly reduce, this be possible to save user Data traffic, while mitigate network pressure.
Fig. 2 is the flow chart of map updating method embodiment two provided in an embodiment of the present invention, such as Fig. 2 institutes Show, the method for the present embodiment includes:
Step S201, the routing information that map rejuvenation server receiving terminal equipment sends, the routing information It is that terminal device is recorded using navigation module.
Specifically, the executive agent of the map updating method that the present embodiment is provided is map rejuvenation server, Map rejuvenation server is arranged on network side, can be by any one network and the terminal with homing capability Equipment is communicated.With reference to embodiment illustrated in fig. 1, terminal device can be by the navigation mould that is provided with Block record path information, after terminal device records are to routing information, can send out to map rejuvenation server Give the routing information.So map rejuvenation server will receive the routing information.
Map rejuvenation server can receive the routing information that terminal device sends in real time, it is also possible to receive To the routing information that terminal device periodically sends, or terminal device can also be received in routing information Reach the routing information sent during preset data amount.
Step S202, when the map data base stored in the routing information with map rejuvenation server is inconsistent When, map rejuvenation server is carried out using the routing information to the map data base in map rejuvenation server Update.
Specifically, after map rejuvenation server receives the routing information of terminal device transmission, can be by The routing information is contrasted with the map datum of storage in map rejuvenation server.If map rejuvenation service When device finds the routing information for receiving and the inconsistent map datum for storing, it is believed that actual road conditions can Can change, it is possible to use the routing information for receiving replaces corresponding path in the map datum for storing. Now complete the map rejuvenation of map rejuvenation server.
Step S203, map rejuvenation server sends map rejuvenation notification message, the map to terminal device Update notification message includes the information being updated to the routing information, so that terminal device uses map Routing information in update notification message is updated to the map data base in terminal device.
Specifically, when map rejuvenation server have updated storage according to the routing information that terminal device sends After map datum, in order that the map in terminal device is also consistent with actual road conditions, it is necessary to terminal device Map rejuvenation notification message is sent, the map rejuvenation notification message includes what routing information was updated Information.Wherein, the routing information that the map rejuvenation notification message includes is that map rejuvenation server is carried out The fresh information in the path of renewal.The information that this pair of routing information is updated is not limited to terminal device to ground Figure updates the routing information that server sends, the road that map rejuvenation server sends according to other-end equipment After footpath information is updated to the map datum in map rejuvenation server, will also send on the path The update notification message of information.In a word, when map rejuvenation server update after the map datum of its storage, Just update notification message can be sent to terminal device, that is, terminal device may at any time receive map Update the map rejuvenation notification message that server sends.And because map rejuvenation server frequently sets to terminal Preparation send the map rejuvenation notification message to consume substantial amounts of data traffic, while can also increase map rejuvenation clothes The pressure of business device, therefore map rejuvenation server periodically can also send update notification to terminal device Message.Or map rejuvenation server to terminal device it is determined that just send out during terminal device access network Map rejuvenation notification message is sent, further, can also be it is determined that terminal device be connect by WiFi network It is fashionable, map rejuvenation notification message just is sent to terminal device, can further save terminal device Data traffic.Or map rejuvenation server can receive the renewal request message of terminal device transmission Just send map rejuvenation notification message to terminal device afterwards.
After terminal device receives the map rejuvenation notification message of map rejuvenation server transmission, you can make The map data base in terminal device is updated with the routing information in the map rejuvenation message.Specifically Update method it is identical with the update method in map rejuvenation server, i.e., using the map rejuvenation that receives Routing information in notification message replaces the path of same place in the map datum stored in terminal device. So that the map datum stored in terminal device is protected with the map datum of storage in map rejuvenation server Hold consistent.
Because the map datum in map rejuvenation server is that the routing information sent according to terminal device is carried out Update, and terminal device can send the routing information of record to map rejuvenation server at any time so that The data stored in map rejuvenation server ensure that real-time update, so as to shorten map rejuvenation service The update cycle of map datum in device, namely the update cycle of map datum in terminal device is shortened, There is provided after the rational transmission cycle, can ensure that the map in terminal device keeps with actual road conditions substantially Unanimously, improve the precision that user's using terminal equipment is navigated.
Map updating method provided in an embodiment of the present invention, map rejuvenation server receiving terminal equipment sends Routing information, when the map data base stored in the routing information and map rejuvenation server is inconsistent, Map rejuvenation server is updated using the routing information to the map data base in map rejuvenation server
Terminal device is sent to map rejuvenation server using the routing information that navigation module is recorded, makes ground Figure is updated server the map data base in map rejuvenation server is updated using the routing information, Then map rejuvenation notification message is sent to terminal device, the map rejuvenation notification message is included to the road The information that footpath information is updated, so that terminal device is using the routing information in map rejuvenation notification message Map data base in terminal device is updated, automatically updating for navigation map is realized, and contract The short update cycle, improve the precision that user's using terminal equipment is navigated.
Further, in the embodiment depicted in figure 2, map rejuvenation server receiving terminal equipment sends Routing information, in can also be routing information and terminal device that terminal device detects navigation module record Sent when the map data base of storage is inconsistent.That is, terminal device have recorded routing information Afterwards, routing information can be contrasted with the map datum of storage in terminal device first.Due to terminal In equipment store map datum be from map rejuvenation server obtain, if map rejuvenation server with Map rejuvenation between terminal device can consider that the map datums stored in both are identicals in time, then. Therefore terminal device can first enter before to map rejuvenation server transmitting path information to routing information Row judges, that is, the treatment that should be carried out by map rejuvenation server is placed in terminal device carries out. When terminal device judges that the routing information of record is inconsistent with the map data base of storage in terminal device, Then just to map rejuvenation server transmitting path update notification message, the routing update notifies to disappear terminal device Breath includes above-mentioned inconsistent routing information.And in working as the routing information of terminal device records and terminal device Storage it is consistent when, then terminal device will not send the routing information to map rejuvenation server.
The routing information that so map rejuvenation server is received will be that terminal device has been compared, and work as map After updating the routing information that server receives terminal device transmission, it can again be judged, Can no longer be judged.Because the service of current navigation map is more ripe, map typically will not be Changed on a large scale in short time, therefore so routing information and storage of the terminal device only in record The routing information just is sent, it is necessary to the data volume for sending to map rejuvenation server when routing information is inconsistent To greatly reduce, this is possible to save the data traffic of user, while mitigating network pressure.
