种独立于浏览过程的地图数据更新;客户端程序主动要求更新也即地图升级模块将自动通过第一通信模块发出地图升级连接请求,要求升级此时本地地图数据,通过有线网络或者无线网络发送给地图服务器;除了上述的两种方式之外,用户也可以边浏览边地图更新,即用户在浏览单位附近的地图,当用户需要拖拉地图浏览时,第一通信模块将地图升级模块发出的要求更新单位附近的地图升级连接请求,通过网络发送给地图服务器;地图服务器实时地更新用户正在浏览的单位附近的地图数据;步骤2:地图服务器的第二通信模块将接收到的该地图升级连接请求以总线方式发送给地图版本控制模块;步骤3:地图版本控制模块根据地图升级连接请求计算需要提供的第二地图数据;其中,地图服务器计算第二地图数据具体为:比较第一终端地图数据和服务器中 Species browser independent of the map data update process; offered to the client program upgrade module updates the map i.e. the map will automatically send update connection request via the first communication module, the local map data required to upgrade at this time, is sent to the network via a wired or wireless network map server; addition to the above two methods, the user can browse side edge map update, i.e. in the vicinity of the user's browser unit map, the user needs to drag the map when browsing, a first communication module to requests from the map update module upgrade map upgrade unit near the connection request, the map server transmits to the network; map updating server unit near real-time the user is viewing the map data; step 2: map of the second communication module server stores the received connection request to the map upgrade bus sent to the map version control module embodiment; step 3: map version control module requesting the second map data to be provided is calculated based on the map update; wherein the map server calculates the second map data specifically includes: comparing the first map data and a terminal server in 的地图数据,如比较两者的版本号,或者也可以比较第一地图数据,即需要更新的正在浏览的单位周围的地图,和服务器地图数据中的网格数据大小及字节值,如果大小及字节值相同,表明用户正在浏览的单位周围地图是最新版本的,如果不相同,那么根据比较结果如两者版本不同或者网格不同,将地图服务器已经分割形成的网格分级的地图数据,即块地图, 进行选择向对应终端侧用户正在浏览的单位周围的地图或者车载导航仪中第一地图数据库的一些本地地图,获得需要下载至车载导航仪的更新第一地图数据的第二地图数据;在地图服务器分级的地图数据具体是地图按照市、地级市的单位划分。 Map data, such as comparison between the two version numbers, or may compare the first map data, and the data size of the mesh around the byte values ​​need to be updated, i.e. browsing the map units, the map data in the server and, if the size of and the same byte value, indicating that the user is browsing around the unit is the latest version of the map, if not identical, then the data according to the comparison results of the two different versions, or different meshes, the map server has been divided to form a grid map classification , i.e., the block map, to select the corresponding user terminal side browsing around the car navigation unit map or some local maps the first map database, to obtain a second map needs to be downloaded to the car navigation system update the map data of the first data; the map server hierarchical map data map is divided according to specific units of city, prefecture-level city. 该类设计可以减少用户安装的地理地图,降低用户的费用。 This class is designed to reduce user-installed geographical map, and reduce costs. 其次,地图分级也可按照详细程度(levelOfDetail)将地图分为多个等级,如20级,从1-20 详细程度逐级递增,第一级包括海洋、国家、首都、大洋、大陆,第二级包括第一级的内容但是线和面上包含更多的节点,使地图放大时能更精确的显示。 Second, the map can also be graded according to level of detail (levelOfDetail) The map is divided into multiple levels, such as 20, from 1-20 incremental level of detail, the first stage includes oceans, countries, capitals, oceans, continents, second a first stage comprising a stage content and a plane including the line, but more nodes, enabling more accurate map displayed enlarged. 在接着的每一级中,包括上一级的内容但是包括越来越多的节点,节点可以细化到城市、地区、街道等信息。 At each level in the next, including the level but include a growing number of nodes, the nodes can be refined to information on cities, regions, streets and so on. 再次,地图分块是对同一级别地图进行分割和编码,同时建立分块的索引文件,通过分块可以对地图数据快速的索引、下载、调度、显示。 Again, the map block is on the same level segmentation map and coding, and indexing the file block by block map data can quickly index, download, schedule, display. 块,或者称为网格,是地图下载的最小单位。 Block, or as a grid, is the smallest unit map download. 分级设计使得用户可以先下载低级別的图级,该类图级视野宽,数据体积小,以免用户长时间等待地图下载,而采用后台下载的方法下载高级别的图级。 Hierarchical design allows users to download low-level class diagram, class diagram level wide field of vision, small data volume, in order to avoid long waits for the user to download maps, and use background downloading method to download a high-level diagram level. 分块的设计使得终端可以先下载用户正在浏览的地图块,以免用户长时间等待地图下载,之后采用后台下载的方法下载用户尚未浏览到的块。 Design allows the terminal block can be downloaded to the user's browsing tiles, in order to avoid long waits for the user to download maps, background downloading after using the method to download user has not navigate to the block. 步骤4:第二通信模块通过有线网络或者无线网络将该第二地图数据即需要更新的单位周围的地图数据或者需要更新的本地地图发送给终端;步骤5:第一通信模块接收该第二地图数据,即需要更新的单位周围的地图数据或者需要更新的本地地图存储至第一地图数据库,具体为:需要更新的单位周围的地图数据或者需要更新的本地地图存储在地图数据库的其他存储区;存放原来单位地图数据的第一存储区释放数据,这样更新的单位周围的地图数据或者需要更新的本地地图搬移至第一存储区,这样就完成地图的在线更新。 Step 4: second communication module through a wired network or a wireless network that is the second map data to be updated or the map data around the unit needs to be updated local maps to the terminal; Step 5: a first communication module receives the second map data, i.e., around the unit needs to be updated or needs to update the map data stored in a first local maps map database, in particular: other units around the store map data needs to be updated or needs to be updated local maps stored in the map database; the first storage unit storage area of ​​the original map data release data, around this updated map data or the unit needs to be updated local maps move to the first storage area, thus completing online map update. 上述这种地图更新方法也适用于手机导航仪,具体更新过程与上述车载导航仪相同,在此不赘述。 This map update method described above also apply to mobile navigation device, specifically the update process and the in-vehicle navigation systems the same, is not described herein. 本发明这种在线地图更新方法和系统,提供了3 种更新地图环境。 This online map update method and system of the present invention, provides three updated map of the environment. 一种是用户可以通过客户端界面提供的"地图更新"按钮或者选项点击,主动发起更新地图的要求。 One is the user can provide a "map update" button or click on the option, take the initiative to update the map request by the client interface. 此时可以更新车载导航仪或者手机导航仪中第一地图数据库中存放的本地地图。 At this point you can update the local map car navigation system or mobile phone navigator in the first map stored in the database. 第二种是当车载导航仪或者手机导航仪客户端启动的同时,地图升级模块自动与地图服务器建立连接进行对车栽导航仪或者手机导航仪中第一地图数据库中存放的本地地图进行更新。 While the second is when the car navigation system or mobile phone navigator client starts, the map upgrade module automatically establish a connection with the map server to the local car plant or mobile phone map navigation navigator in the first map stored in the database is updated. 第三种是用户在使用车载导航仪或者手机导航仪时,正在浏览一副地图, 此时地图可以进行实时更新,地图服务器对用户浏览的地图进行实时更新, 用户浏览的哪一个地图块,地图服务器就更新到哪一个地图块。 The third is the user in the use of car navigation device or mobile phone navigation, browsing a map, then the map can be updated in real time map server for users to browse the map in real-time update, which users browse a map tile map update server to which the tiles. 最后所应说明的是,以上实施例仅用以说明本发明的^支术方案而非限制, 尽管参照较佳实施例对本发明进行了详细说明,本领域的普通技术人员应当理解,可以对本发明的技术方案进行修改或者等同替换,而不脱离本发明技术方案的精神和范围。 Finally, it should be noted that the above embodiments are merely to illustrate and not limit ^ branching operation according to the present invention, although the present invention has been described in detail with reference to preferred embodiments, those of ordinary skill in the art should be understood that the present invention technical solutions modifications or equivalent replacements without departing from the spirit and scope of the technical solutions of the present invention.
