构建电子地图定位数据库的方法及系统 Method for constructing electronic map positioning systems and databases

技术领域 FIELD

[0001] 本发明涉及信息技术领域,尤其涉及一种构建电子地图定位数据库的方法及系统。 [0001] The present invention relates to the field of information technology, particularly to a method and system for constructing an electronic map location databases.

背景技术 Background technique

[0002] 在电子地图上实现定位的方法,一般可包括WIFI定位、基站定位和GPS定位。 [0002] The method implemented is positioned on an electronic map, positioned generally include WIFI, base station positioning and GPS positioning.

[0003] WIFI是一种无线连接技术,可以在电脑、手机等终端间进行无线数据传输。 [0003] WIFI connection is a wireless technology, wireless data transmission between computers, mobile phones and other terminals. WIFI 作为目前无线传输的主要技术,在各行各业被广泛使用,其是以太网的一种无线扩展,理论上只要用户位于一个接入点四周的一定区域内,就能以最高约llMb/s的速度接入ffeb。 As the main WIFI wireless transmission technology, and it is widely used in various industries, which is a wireless extension of Ethernet, as long as the user is located within a theoretically access point around a certain area, can be up to about llMb / s speed access ffeb. 但实际上,如果有多个用户同时通过一个点接入,带宽被多个用户分享,WIFI的连接速度一般将只有几百ΙΛ/s。 But in fact, if there are a plurality of users simultaneously through the access point, the bandwidth is shared by a plurality of users, WIFI connection speeds will generally only a few hundred ΙΛ / s.

[0004] WIFI定位是基于以下条件实现的:WIFI热点(Access Point, AP, WIFI信号源) 越来越多,在城市中更趋向于空间任何一点都能接收到至少一个WIFI热点信号。 [0004] positioned WIFI is implemented based on the following conditions: WIFI hotspot (Access Point, AP, WIFI signal source) more and more, in cities tend to any point in space can receive at least one signal WIFI hotspots. 热点只要通电,不管它怎么加密的,都一定会向周围发射信号。 Hot long as the power, no matter how it is encrypted, it will transmit signals to the surroundings. 该信号中包含此热点的唯一全球ID, 即是MAC地址。 Global unique ID included in the signal of this hot spot, i.e. a MAC address. 即使距离此热点比较远,无法建立连接,但还是可以侦听到它的存在。 Even relatively far from this hot spot, unable to establish a connection, but you can still listens to its existence. 热点一般都是很少变位置的,比较固定。 Hot generally little change position, relatively fixed. 定位端可以通过检测附近的热点,并将该热点信息发送至服务器,并由该服务器根据热点信息,将存储于该服务器中的定位数据库中的相应地理坐标发送至定位端,实现定位。 End may be positioned, and sent through the hot spot near the hot spot information to the server detected by the server according to the hot spot information stored in the respective geographic coordinates of the location server database and transmitted to the locating, positioning achieved. 虽然WIFI定位精度比GPS要低,受服务范围限制,而且没有方向、速度等数据,不能导航,更不能离线使用等,但它有比GPS更优越的地方,就是在人口、楼群越密集的地方,使用的效果会更好。 Although WIFI GPS positioning accuracy is lower than, the restricted scope of services, and there is no direction, speed and other data, can not navigate, but can not be used offline and so on, but it has a superior place than GPS, it is more densely populated, the buildings local effect, would be better used. GPS启动时间长,且在室内是无效的,天气不好的时候表现也欠佳,楼群太密集的地方也不太好用,这些因素都被WIFI定位克服了。 GPS starts a long time, and indoors is invalid, bad weather performance is poor, the place is not too dense buildings in handy, WIFI locate these factors are overcome. 然而, 若想实现WIFI定位,这需要逐一采集WIFI的MAC地址和对应的位置信息,并将该MAC地址和位置信息进行绑定,并构建定位数据库,以方便定位端查询。 However, if you want to achieve WIFI positioning, which requires individually collected WIFI MAC address and the corresponding position information, and the MAC address and bind the location information, and location database constructed to facilitate locating the query.

[0005] 另外,对于基站的定位,因基站的位置一般来说是相对固定的,现有的做法大多通过多个基站检测在其覆盖区域内的移动终端,并通过三角计算,得到该移动终端的位置。 [0005] Further, the positioning of the base station, depending on the position of the base station is generally fixed relative to existing practices mostly through the base station detects a plurality of mobile terminals within its coverage area, and by triangulation, the mobile terminal obtained s position. 然而,这种基于三角计算的定位准确度较差,若要使准确度提高,则需要逐一采集基站位置的CELL ID和位置信息,并将该CELL ID和位置信息进行绑定,并构建定位数据库,以方便定位端查询。 However, this is based on triangulation positioning accuracy is poor, so to improve the accuracy, it is necessary CELL ID and location information of the base station acquired by one position, and the CELL ID and bind the location information to locate the database and constructs to facilitate locating the query.

[0006] 然而,现有技术中的WIFI的MAC地址和位置信息、基站的CELL ID和位置信息只能逐一采集,即是在同一地点时,每一次采集只能采集到一个MAC地址或者一个CELL ID,这样的采集方式,在现实中,特别是对于城市而言,同一地点存在的基站信号和WIFI信号可能有多个,若还是采用现有技术中的逐一采集,则在每一个地点上都需要花较多的时间进行采集,从而导致采集效率非常低,采集数据周期非常长,很不利于构建电子地图定位数据库。 [0006] However, CELL ID and the position information in the prior art WIFI MAC address and location information, the base station can only collect one by one, that is, at the same location, each acquisition to collect only a MAC address or a CELL ID, this acquisition mode, in reality, in particular for urban, WIFI base station signal and the signals present the same location may have multiple, one by one if the acquisition or the use of the prior art, then in each location on need to spend more time acquisition, resulting in a very low collection efficiency, data collection cycle is very long, very conducive to building a digital map to locate the database.

[0063] 过滤初始数据步骤S3 :在服务器上去除不符合定位要求的初始数据,值得一提的是,此步骤并非本发明的必要步骤,只是为了更好的进行下述的推算步骤S4而做的预处理; [0063] The initial data filtering step S3: On the server does not meet the removal requirement of the original data location, it is worth mentioning that this step is not essential for the present invention, merely to better estimation is performed following step S4 done pretreatment;

[0066] 步骤S3的说明:对于初始数据,其中可能存在地理坐标与CELL ID偏差较大的数据,一般这种偏差是来源于移动通信终端的GPS在某段时间内无法连接卫星而导致,需要进行过滤,否则会严重影响后续的推算模块的准确性。 DESCRIPTION [0066] Step S3: the initial data, and wherein there may be geographical coordinates large deviation data CELL ID, such deviation is typically a mobile communication terminal from GPS satellite can not be connected in a certain period of time resulting, need filter, otherwise it will seriously affect the accuracy of subsequent projections module. 请参考图2,过滤的方法是对接收到的初始数据进行一系列的处理,具体流程依次如下: Please refer to FIG. 2, the method of filtration is the received initial data series of the processing, the specific process sequence is as follows:
