Description

一种基于智能终端的导航方法及导航系统 技术领域
本发明涉及智能终端领域，尤其涉及一种基于智能终端的导航方法及导航系统。
背景技术
随着社会经济的发展，人们的消费水平越来越高，购物需求也越来越旺。但对于消费者来说，中心商圈由于竞争激烈，各种大型商场与超市林立，而其中的商品更是琳琅满目、花样繁多，消费者需要采购的商品可能分布在不同的商场或超市的各个区域或角落，消费者在寻找合适满足自己购物清单上所有商品的商场及寻找商品的过程中浪费很多时间。
从传统时代到网络时代，互联网(WEB)与移动应用(Mobile)得到了爆发性的普及。从应用的绝对人口数和接触时长来说，这些后起之秀达到甚至超越了电视、报纸等传统媒介。如果说第一代互联网同电视、报纸一样承担了信息发布者的角色，网络搜索引擎则提供了与传统媒介完全不同的、主动、精准获取信息的可能性，而这也为消费者快速寻找合适的商场及商品提供了可能性。
而在日常工作和生活中，人们常常会用到一些具有地图定位功能的应用以确定自身所处的地理位置以及所需到达目的地的地理位置，并且寻求获得到达该目的地的路线。手机导航(Mobile Navigation)就是通过导航手机的导航功能，把用户从目前所在的地方带到另一个想要到达的地方，它与手机电子地图的区别就在于，它能够告诉用户在地图中所在的位置，以及用户要去的那个地方在地图中的位置，并且能够在用户所在位置和目的地之间选择最佳路线，并在行进过程中的为用户提示左转还是右转等，这就是所谓的导航。具有定位和导航功能的手机正日益受到消费者的追捧，市场前景看好。
目前，市面上的手机导航分为三类，第一类是真正的通过太空中的卫星进行GPS(Global Position System，全球定位系统)导航，精度在3-5米；第二类是通过基站网络进行粗略的导航的，称为CELLID导航，这种导航没有真正的通过卫星GPS导航的精确，一般定位误差为100米；第三类是AGPS+CELLID+GPS定位，这种导航最为精确，在室 内默认是CELLID定位，在室外先利用AGPS搜到星图，达到快速定位，然后自动切换到GPS高精度定位并进行导航。
手机导航一般通过GPS模块、导航软件、GSM通信模块相互分工，配合完成：1.GPS模块完成对GPS卫星的搜索跟踪和定位速度等数据采集工作；2.导航软件地图功能将GPS模块得到位置信息，不停地刷新电子地图，从而使用户在地图上的位置不停地运动变化；3.导航软件路径引导计算功能，根据用户的需要，规划出一条到达目的地的行走路线，然后引导用户向目的地行走。4.GSM通信模块完成手机的通讯功能，并可根据手机功能对采集来的GPS数据进行处理并上传指定网站。
因此，本发明提供了一种基于智能终端的导航方法及导航系统，其中，导航方法包括以下步骤：设定包含一个或多个待购商品的商品清单；连接一本地或云端数据库，搜索满足商品清单的商户信息；获取满足商品清单的商户信息的商户地址；调用智能终端的定位装置，获取智能终端的当前位置；调用智能终端的导航装置，根据商户地址及智能终端的当前位置，规划前往商户地址的导航路线；显示导航路线。本发明结合了网络搜索引擎及终端导航功能，为用户快速精确的寻找合适的商场及商品，同时规划前往商场及购买商品的导航路线，极大地节省了用户的时间和金钱，提高了用户的购物效率，提高了用户的使用体验。

这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
在本发明使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本发明。在本发明和所附权利要求书中所使用的单数形式的“一”、“一种”、“所述”、“该”等也旨在包括多数形式，除非上下文清楚地表示其他含义。
应当理解，尽管在本发明可能采用术语第一、第二等来描述各种获取模块，但不应限于这些术语。这些术语仅用来将同一类型的获取模块彼此区分开。例如，在不脱离本发明范围的情况下，第一获取模块也可以被称为第二获取模块，类似地，第二获取模块也可以被称为第一获取模块。取决于语境，如在此所使用的词语“当……时”可以被解释成为“在……时”或“如果”或“响应于确定”。
在本发明的描述中，需要理解的是，术语“上”、“下”、“前”、“后”、“左”、“右”、指示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
在本发明的描述中，除非另有规定和限定，需要说明的是，术语“连接”等应做广义理解，例如，可以是机械连接或电连接，也可以是两个元件内部的连通，可以是直接相连，也可以通过中间媒介间接相连，对于本领域的普通技术人员而言，可以根据具体情况理解上述术语的具体含义。
在后续的描述中，使用用于表示元件的诸如“模块”、“单元”的后缀仅为了有利于本发明的说明，其本身并没有特定的意义。因此，“模块”与“单元”可以混合地使用。
本发明的导航方法及导航系统，可以应用于智能终端，智能终端可以以各种形式来 实施。例如，本发明中描述的智能终端可以包括诸如移动电话、智能电话、笔记本电脑、PDA(个人数字助理)、PAD(平板电脑)、PMP(便携式多媒体播放器)、导航装置、智能手表等的智能终端，以及诸如数字TV、台式计算机等的固定终端。下面，假设终端是智能终端，并假设该智能终端为智能手机，对本发明进行说明。然而，本领域技术人员将理解的是，除了特别用于移动目的的元件之外，根据本发明的实施方式的构造也能够应用于固定类型的终端。为便于描述，本发明实施例均以智能手机为例进行说明，其它应用场景相互参照即可。
参考图1，本发明的基于智能终端的导航方法，包括以下步骤：
S100：于所述智能终端内，设定包含一个或多个待购商品的商品清单；
S200：连接一本地或云端数据库，搜索满足所述商品清单的商户信息；
S300：获取满足所述商品清单的所述商户信息的商户地址；
S400：调用所述智能终端的定位装置，获取所述智能终端的当前位置；
S500：调用所述智能终端的导航装置，根据所述商户地址及所述智能终端的当前位置，规划前往所述商户地址的导航路线；
S600：显示所述导航路线。
具体地：
-S100：于所述智能终端内，设定包含一个或多个待购商品的商品清单；
商品清单的设定可以是用户手动输入设定的，也可以是系统提供商品选项由用户选择设定的。商品清单内所包含的待购商品可以是一个或多个，一个或多个待购商品的内容包括但不限于待购商品的品牌、品名、规格、产地、功效、使用方法、储存方法、注意事项、图示等。
-S200：连接一本地或云端数据库，搜索满足所述商品清单的商户信息；
其中，满足所述商品清单的商户信息是指，该商户中包含了用户所要购买的商品清单上的全部商品。
具体在连接数据库时，可以有多种方式，例如连接本地数据库，预先通过网上下载、人工收集等方式获取各个商场及商品的相关信息，并保存到本地数据库中，但是对于智能设备飞速发展的时代而言，在实际连接使用这种方式创建的本地数据库时，往往存在以下问题，用户希望购买的商品种类各异、名目繁多，而本地数据库的方式能够提供的商场及商品的数量往往是非常有限的，不可能全面覆盖到所有用户可能购买的所有商品，可能在本地数据库中未保存该商品，这时便会出现检索失败。为此，本实施例中，还可以连接一基于网络平台的网络数据库而生成的云端数据库，通过云端数据库中的海量资 源进行商品的检索。
-S300：获取满足所述商品清单的所述商户信息的商户地址；
参考图2，在一优选实施例中，S300：获取满足所述商品清单的所述商户信息的商户地址的步骤包括：
获取满足所述商品清单的多个所述商户信息中所述待购商品的价格；
比较满足所述商品清单的多个所述商户信息中所述待购商品的价格高低；
获取所述待购商品的价格最低的所述商户信息的所述商户地址。
进一步地，S600：显示所述导航路线的步骤还包括：
显示一个或多个所述待购商品的价格。
参考图3，在一优选实施例中，S300：获取满足所述商品清单的所述商户信息的商户地址的步骤包括：
获取用户输入的导航方式，所述导航方式包括出租车、驾车、公交、步行、骑行中的一种或多种；
获取所述智能终端的当前时间；
根据所述导航方式及所述当前时间，获取前往时间最短的所述商户信息的所述商户地址。
参考图4，在一优选实施例中，S300：获取满足所述商品清单的所述商户信息的商户地址的步骤包括：
显示所有满足所述商品清单的所述商户信息；
获取用户选择的所述商户信息的商户地址。
上述实施例中，在检索到的满足用户商品清单的商户中进行筛选，筛选的条件可以是，所要购买的商品清单中的商品价格的高低，或者是，用户前往时间最短的商户，或者是，由用户在所有满足用户商品清单的商户中自行选定。当筛选的条件是所要购买的商品清单中的商品价格的高低时，同时显示各个商户中商品的价格信息及不同商户中相同商品的价格对比。当由用户自行选定时，同样可以获取各个商户中各个商品的价格信息，显示各个商户中商品的价格信息及不同商户中相同商品的价格对比，以便用户选择合适的商户进行购买。
-S400：调用所述智能终端的定位装置，获取所述智能终端的当前位置；
-S500：调用所述智能终端的导航装置，根据所述商户地址及所述智能终端的当前位置，规划前往所述商户地址的导航路线；
-S600：显示所述导航路线。
现有技术中，智能终端的导航装置一般通过定位装置、导航软件、通信装置相互分工，配合完成。
一、按照定位导航的策略来区分，智能终端定位导航技术可以分为基于智能终端的定位导航技术、基于网络的定位导航技术以及两者的混合定位导航技术：
1、基于智能终端的定位技术
基于智能终端的定位技术是指定位计算由智能终端自己完成，智能终端可以自行确定自己的当前位置，也称为智能终端的自定位，在蜂窝网络中又叫做前向链路定位。该技术便于保护智能终端用户的隐私(即用户当前的位置信息)不受侵犯，但是要求智能终端有较强的计算能力和持久的供电能力。
2、基于网络的定位技术
基于网络的定位技术主要由网络系统收集待定位智能终端的信息并计算智能终端的当前位置，在蜂窝网络中又叫做反向链路定位。该技术要求待定位智能终端发送或广播一些特定的信号；网络系统负责收集这些信号并担负起定位计算的任务。在实际应用中，通过一些策略控制也可以有效地保护用户的隐私。
二、从定位导航原理来看，可以分为三角测量定位技术、场景分析定位技术和邻近关系定位技术。智能终端定位技术的性能优劣往往由它所遵循的定位原理来决定。
1、三角测量定位技术
三角测量定位技术根据测量得出的数据，利用几何三角关系计算被测物体的位置。它是最主要和应用最为广泛的定位技术，包括距离测量定位技术和角度测量定位技术。
(1)距离测量定位技术
距离测量定位技术需要测量位置已知的参考点与被测物体之间的距离。测距方法有很多：
-能量衰减测量法。已知电磁波的发射强度，测量接收到的电磁波强度，以估计与电磁波发射端的距离。电磁波在空间传播时，能量的衰减是多种因素共同作用的结果，而不是只与传播距离有关，所以能量衰减测量法往往精度不高。基于该方法的定位技术GeoMode已成功服务于纽约和中国长沙等众多城市，它通过测量多个基站已经存在的RF信号电平，并分析手机信号和网络参数来确定客户端的准确位置。
-传播时间测量法。已知电磁波的传播速度，电磁波的传播距离与传播时间成正比。需要注意的问题有多径效应、时钟精度、时钟同步。应用此种方法的定位技术最为广泛，包括TOA、TDOA、EOTD、OTDOA、GPS。
-到达相位测量法。已知参考点与被测物体的大概距离，测量接收到的载波相位以实 现更精确的距离测量。GPSRTK(global positioning system real-time kinematic)就是先通过传播时间测量法计算出参考点与被测物体的大概距离(即求解整周模糊度)；再通过到达相位测量法确定它们之间的精确距离，以实现厘米级的定位精度。
(2)角度测量定位技术
角度测量定位技术需要测量位置已知的参考点与被测物体之间的方位角。该技术需要使用方向性天线，如智能天线阵列。典型的有AOA定位技术。
2、场景分析定位技术
场景分析定位技术对定位的特定环境进行抽象和形式化，用一些具体的、量化的参数描述定位环境中的各个位置，并用一个数据库把这些信息集成在一起。观察者根据待定位物体所在位置的特征查询数据库，并根据特定的匹配规则确定物体的位置。这种定位技术的核心是位置特征数据库和匹配规则，它本质上是一种模式识别方法，如RFfingerprinting定位技术。
3、邻近关系定位技术
邻近关系定位技术根据待定位物体与一个或多个已知位置的邻近关系进行定位。这种定位技术通常需要标志系统的辅助，以惟一的标志来确定已知的各个位置。最常见的就是COO或称为cell ID定位技术。
综上，现有无线定位技术主要有以下几种：
1、基于电波传播时间(TOA)
若电波从移动台到基站的传播时间为t，电波传播速度为c，则移动台位于以基站位置为圆心，以c×t为半径的圆上。在多个基站上进行上述计算，则移动台的二维位置坐标可由三个圆的交点确定。基于TOA的无线定位，1μs的时间误差将导致300m左右的定位误差，因此要求基站有非常精确的时钟，收发信号的双方能够精确同步；
2、基于电波传播时间差(TDOA)
通过检测信号到达两个基站的时间差，而不是到达的绝对时间来确定移动台的位置，降低了时间同步要求。根据信号到达时间差，移动台位于以两个基站为焦点的双曲线上，要确定移动台的位置，至少需要三个基站，建立两个双曲线方程，两个双曲线的交点即为移动台的二维位置坐标；
3、基于电波入射角(AOA)
通过基站接收机天线阵列测出移动台发射电波的入射角，采用一定的算法确定由角度决定的方位线的交点，即为被测移动台的位置。该方法适合于视距传播的情况，设备复杂度较高；
4、单元标识(Containment)
通过蜂窝提供的信息，确定移动用户是否在该蜂窝覆盖范围内，该方法只能定位到一个蜂窝或者扇区的范围内，精度很低；
5、基于信号强度(RSS)
研究表明，无线信号传播存在以下规律：接收方测得的信号强度越强，发送方距离接收方往往越近，接收到的信号强度越弱，发送方距离往往越远。因此，通过测量接收到的信号强度可以推算出移动台到基站的距离。
