上述技术方案采用BLE的MESH网络与蜂窝移动通信网络结合的方式对目标物体进行定位,蓝牙定位基站通过MESH网络将定位数据发送到MESH网关,再由MESH网关将定位数据通过蜂窝移动通信网络发送到定位服务器。由于一个定位系统最少可以配置一个MESH网关,一个BLE模块可以与一个蜂窝移动通信模块组合为一个MESH网关,这样可以不用给每个目标物体都安装蜂窝移动通信模块,从而可以有效降低成本,适合大规模部署。此外,每座蓝牙定位基站可以覆盖半径数百米~2千米的范围,因此,可以使用少量的蓝牙定位基站就可以覆盖数平方公里的范围,有利于降低建设成本与维护成本。
进一步地,蓝牙定位基站可以依靠电池、太阳能和风力供电,从而可以持续工作数年。此外,MESH网络的定位精度最高可以达到厘米级,从而可以实现高精度定位。

具体实施方式
下面将结合附图,对本申请实施例中的技术方案进行描述。
目前的定位方式主要有以下几种:
(1)基于卫星定位系统,即全球定位系统(Global Positioning System,GPS)的定位方式
GPS接收机功耗较大,如果需要长期跟踪某个动物,则需要为该动物配置体积较大的电池,因此,GPS定位方式不适用于小型动物。进一步地,如果定位设备需要自动发送动物移动轨迹数据,则还需要在定位设备上增加蜂窝移动通信模块,这样会进一步增大定位设备的功耗与体积,且成本较高,不适合大规模的部署。
(2)采用无线电定位项圈的方式
该定位方式是最传统的定位方式,构造简单、可靠性高、定位设备价格便宜,但是需要人工无线电三角定位。该定位方式的人力需求较多,工作强度很大,导致综合成本较高,无法跟踪较多的动物。
(3)基于星光定位系统的定位方式
星光定位器虽然体积小、重量轻,但是定位精度低,所以一般适用于数千到上万公里移动距离的跟踪,而不适合农场、野生动物园、动物野放基地等相对小尺度的范围。
(4)基于蜂窝移动通信网络的定位方式
该定位方式的定位精度低,尤其是在地形复杂、基站密度很低的野外地区。此外,该定位方式的定位设备包括蜂窝移动通信模块,蜂窝移动通信模块的功耗较大、成本较高,不适合大规模部署。
鉴于此,本申请实施例提出了一种定位方法,本申请实施例的定位方法采用低功耗蓝牙(Bluetooth Low Energy,BLE)的MESH网络和蜂窝移动通信网络联合组网的方式,可以实现低成本、高精度、长时间地对一定区域内的物体定位的目的。
为了更清楚地理解本申请实施例的方案,下面首先对MESH网络进行简单描述。
图1是一种可能的MESH网络的示意图。该MESH网络中包括多个设备,每个设备可以称为一个节点(node)。每个节点都可以进行数据传输。数据包可以在各个节点之间被中继,从而使该数据包传输至距离更远的位置。在实际应用中,这些节点可以被分布在制造工厂、办公楼、购物中心、商业园区、家庭以及其他环境中。该MESH网络中可以包括任意数量的节点,图1中仅以节点A至节点G为例。在MESH网络中,数据包基于广播(advertising)的方式进行传输。每个节点接收另一节点发送的数据包后,对该数据包进行无条件转发,从而将该数据包转发给附近其他节点。
例如,从节点A至节点B的数据包可以经过至少一次中继。其中,节点C接收到节点A发送的数据包后,可以将该数据包转发给节点D和节点G;节点D接收到该数据包后,可以将该数据包分别转发给节点G和节点B;节点G接收到该数据包后,可以将该数据包转发给节点B、节点E和节点F。由于是基于advertising的方式进行数据包传输,数据传输不可靠,因此,节点A向节点B发送该数据包时,可以多次重复发送该数据包,以确保数据包成功接收。
图2是本申请实施例的定位的方法的流程交互图。图2所示的方法200可以应用于BLE的MESH网络与蜂窝移动通信网络的混合无线系统中。该混合无线系统可以包括多个蓝牙定位基站、MESH网关以及定位服务器,其中,多个蓝牙定位基站可以通过MESH网络与MESH网关通信,MESH网关可以通过蜂窝移动通信网络与定位服务器进行通信。
图3为一种可能的混合无线系统的示意图。应理解,在本申请实施例中,混合无线系统也可以称为定位系统,本申请实施例对此不作具体限定。图3所示的定位系统包括3个蓝牙定位基站,分别为第一蓝牙定位基站、第二蓝牙定位基站和第三蓝牙定位基站,这三个蓝牙定位基站组成了MESH网络。此外,图3所示的定位系统还包括MESH网关和定位服务器。其中,MESH网关可以由一个BLE模块与一个蜂窝移动通信模块组成。
第一蓝牙定位基站、第二蓝牙定位基站以及第三蓝牙定位基站中的任意蓝牙定位基站可以通过MESH网络将数据发送到MESH网关。比如,由于第一蓝牙定位基站距离MESH网关较远或第一蓝牙定位基站与MESH网关之间有阻挡物,第一蓝牙定位基站无法直接连接到MESH网关,第一蓝牙基站可以将数据发送给第二蓝牙定位基站,再由第二蓝牙定位基站将数据转发 给MESH网关。
如图2所示,该方法200可以包括以下内容中的至少部分内容。需要说明的是,至少一个蓝牙定位基站包括第一蓝牙定位基站,本申请实施例仅以第一蓝牙定位基站为例进行说明,但本申请并不限于此,该至少一个蓝牙定位基站中除第一蓝牙定位基站中的其他蓝牙定位基站可以执行与第一蓝牙定位基站相同的行为。
在210中,第一蓝牙定位基站获取定位指令。
作为一种示例,该定位指令可以是预设在第一蓝牙定位基站上的。比如,可以在第一蓝牙定位基站上预设每天的12点第一蓝牙定位基站获取定位指令。再比如,可以在第一蓝牙定位基站上预设每隔10min获取定位指令。
作为另一种示例,定位服务器可以通过蜂窝移动通信网络,向MESH网关发送定位指令,MESH网关接收到该定位指令后,可以通过MESH网络向蓝牙定位基站发送定位指令。可选地,此处的蓝牙定位基站可以只包括第一蓝牙定位基站,即MESH网关可以只向第一蓝牙定位基站发送定位指令。可选地,此处的蓝牙定位基站可以包括定位系统中的所有蓝牙定位基站,如图3中的第一蓝牙定位基站、第二蓝牙定位基站和第三蓝牙定位基站。
在220中,第一蓝牙定位基站基于定位指令,获取第一蓝牙定位基站范围内的目标物体相对于第一蓝牙定位基站的定位数据。
其中,目标物体可以是但不限于动物、机器人、商场或超市内的购物车、共享单车等。参考图3,第一蓝牙定位基站内范围内的目标物体为动物2和动物4。
目标物体上可以设置有定位器,定位数据可以包括第一蓝牙定位基站根据目标物体上设置的定位器发送的定位信号确定的定位信号数据。
可选地,该定位器可以为蓝牙定位器,如微型BLE定位器。微型BLE定位器的体积可以小到纽扣大小,并依靠电池持续工作数月到数年,因此不仅适用于大型物体,如大型哺乳动物,同样也适合于小型物体,如小型家禽。此外,与卫星定位相比,BLE定位器定位速度快、时间短,从而可以节省功耗。
可选地,定位数据可以为目标物体与第一蓝牙定位基站之间的接收信号强度指示(Received Signal Strength Indication,RSSI)和/或信号接收角度。具体而言,目标物体上设置的BLE定位器发射定位信号,第一蓝牙定位基 站接收到BLE定位器发射的定位信号后,可以获取到目标物体与第一蓝牙定位基站之间的RSSI和/或信号接收角度。
在230中,第一蓝牙定位基站向MESH网关发送定位数据,该定位数据用于定位服务器确定目标物体的位置信息。为了后续描述方便,将第一蓝牙定位基站向MESH网关发送的定位数据称为第一定位数据。
第一蓝牙定位基站向MESH网关发送的第一定位数据可以是计算后的定位数据,也可以是未计算的定位数据(为了描述方便,称为原始定位数据)。
也就是说,第一蓝牙定位基站获取到原始定位数据后,在一种实现方式中,可以在本地计算原始定位数据,计算完成后,第一蓝牙定位基站向MESH网关发送计算后的定位数据。
在另一种实现方式中,第一蓝牙定位基站可以不在本地计算原始定位数据,即不对原始定位数据进行处理,而是直接将原始定位数据发送给MESH网关。此时,原始定位数据与第一定位数据相同。在该实现方式中,蓝牙定位基站不计算原始定位数据,使得可以降低蓝牙定位基站的运算与存储负担,进一步可以降低蓝牙定位基站的功耗。
第一蓝牙定位基站向MESH网关发送第一定位数据的一种可能的发送方式可以包括:第一蓝牙定位基站获取到第一定位数据后,立即向MESH网关发送第一定位数据。
第一蓝牙定位基站向MESH网关发送第一定位数据的另一种可能的发送方式可以包括:第一蓝牙定位基站在预设时间内发送第一定位数据。例如,预设时间可以是第一蓝牙定位基站获取到第一定位数据的N ms。如N=5,即第一蓝牙基站获取到第一定位数据后,可以在5ms后向MESH网关发送第一定位数据。再例如,预设时间可以是每天的整点时间,即每天的6点、7点、8点等,如第一蓝牙基站在13:20获取到第一定位数据,则第一蓝牙基站可以在14点向MESH网关发送第一定位数据。
进一步地,第一定位数据还可以包括目标物体的标识和/或第一蓝牙定位基站的标识。在该示例中,定位服务器中存储有物体标识和物体之间的对应关系,和/或,定位服务器中存储有蓝牙定位基站的标识和蓝牙定位基站之间的对应关系。
可选地,目标物体的标识可以是目标物体的索引或编号。目标物体的编号可以为目标物体在定位系统内的编号。
应理解,本文中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。
进一步地,第一蓝牙定位基站还可以向MESH网关指示发送第一定位数据的时间戳。
该时间戳可以是采用世界标准时间的时间戳。或者,该时间戳可以是基于MESH网络的局域时间的时间戳(为了描述方便,称为局域时间戳)。其中,MESH网络的局域时间的数据长度小于世界标准时间的数据长度。比如,世界标准时间为年月日时分秒,MESH网络的局域时间可以为时分秒。
MESH网络的局域时间的数据长度小于世界标准时间的数据长度,如此,可以减少数据量,降低功耗。
若时间戳为局域时间戳,在本申请实施例中,MESH网关还需要确定局域时间,之后,第一蓝牙定位基站需要与MESH网关完成局域时钟同步。
MESH网关接收到局域时间戳后,MESH网关可以不对局域时间戳进行处理,或者,MESH网关可以根据局域时间与世界标准时间的对应关系,计算出第一蓝牙定位基站发送定位数据的世界标准时间戳。
在240中,MESH网关通过蜂窝移动通信网络,向定位服务器发送定位数据。为了描述方便,将MESH网关向定位服务器发送的定位数据称为第二定位数据。
应理解,在本申请实施例中,“第一”和“第二”仅仅为了区分不同的对象,但并不对本申请实施例的范围构成限制。
其中,第二定位数据可以包括目标物体与第一蓝牙定位基站之间的RSSI和/或信号接收角度,第二定位数据还可以包括目标物体的标识和/或第一蓝牙定位基站的标识。
进一步地,第二定位数据还可以包括第一蓝牙定位基站发送第一定位数据的时间戳。
若MESH网关向定位服务器发送的时间戳是局域时间戳,在该情况下,可选地,第二定位数据还可以包括局域时间与世界标准时间的对应关系。比如,第二定位数据还可以包括局域时间的起始时间对应的世界标准时间。或者,第二定位数据可以不包括局域时间与世界标准时间的对应关系,此时,定位服务器中保存有MESH网关在之前的某一时刻向定位服务器发送的局 域时间与世界标准时间的对应关系。
也就是说,MESH网关每次向定位服务器发送的第二定位数据中并不一定包括局域时间与世界标准时间的对应关系,MESH网关可以在之前的任意时刻单独向定位服务器发送局域时间与世界标准时间的对应关系,并指示定位服务器之后接收到的第二定位数据皆以此对应关系为基准。这样的话,MESH网关之后向定位服务器发送第二定位数据时,第二定位数据中可以不包括局域时间与世界标准时间的对应关系。当MESH网关需要更新局域时间时,MESH网关可以单独向定位服务器发送更新后的局域时间与世界标准时间的对应关系,或者,第二定位数据中可以包括更新后的局域时间与世界标准时间的对应关系。
若MESH网关通过蜂窝移动通信网络,未成功向定位服务器发送第二定位数据,则MESH网关可以保存第二定位数据,并在第一时间内重新向定位服务器发送该第二定位数据。
可选地,第一时间可以是预设在MESH网关上的。例如,可以在MESH网关上预设第一时间为MESH网关未成功发送第二定位数据之后的10ms。
可选地,MESH网关可以对应一个定时器。在MESH网关向定位服务器发送第二定位数据时,该定时器开启,若MESH网关未成功发送第二定位数据,在该定时器超时之前,MESH网关不能向定位器重新发送该第二定位数据。
在250中,定位服务器接收到第二定位数据后,根据第二定位数据确定目标物体的位置信息。
具体而言,定位服务器可以根据定位信号数据,确定目标物体与第一蓝牙定位基站之间的相对位置,然后,定位服务器可以根据相对位置和第一蓝牙定位基站的位置信息,确定目标物体的位置信息。
可选地,定位服务器可以提前存储第一蓝牙定位基站的位置信息。
其中,定位服务器确定的目标物体的位置信息可以包括目标物体在地理坐标系中的坐标,第一蓝牙定位基站的位置信息可以包括第一蓝牙定位基站在地理坐标系中的坐标。或者,定位服务器确定的目标物体的位置信息可以包括目标物体在多个区域中的哪个区域。
进一步地,若第二定位数据中包括目标物体的标识和/或第一蓝牙定位基站的标识,定位服务器接收到第二定位数据后,可以根据目标物体的标识, 以及根据物体标识和物体的对应关系,确定目标物体;和/或,定位服务器可以根据第一蓝牙定位基站的标识,以及根据蓝牙定位基站的标识和蓝牙定位基站之间的对应关系,确定第一蓝牙定位基站。
在定位服务器确定第一蓝牙定位基站后,可以在存储的多个蓝牙定位基站的位置信息中找到第一蓝牙定位基站的位置信息,从而可以根据目标物体与第一蓝牙定位基站之间的相对位置,以及根据第一蓝牙定位基站的位置信息,确定目标物体的位置信息。
进一步地,若第二定位数据中包括的时间戳为局域时间戳,则定位服务器可以根据局域时间戳和世界标准时间的对应关系,确定目标物体的位置信息对应的世界标准时间戳。
在定位服务器确定了目标物体在一段时间内的位置信息和位置信息对应的世界标准时间戳之后,可以确定目标物体的活动轨迹,从而可以更好地实现对目标物体的跟踪。
需要说明的是,若目标物体周围的若干个蓝牙定位基站(即上文提到的至少一个蓝牙定位基站)都可以接收到目标物体发送的定位信号,并且该若干个蓝牙定位基站都根据接收到的定位信号确定了目标物体相对于自身的第一定位数据,并通过MESH网关将第一定位数据都发送给了定位服务器,则定位服务器可以根据来自若干个蓝牙定位基站的具有同样时间戳的第一定位数据,确定目标物体的位置信息。
再次参考图3,第一蓝牙定位基站、第二蓝牙定位基站和第三蓝牙定位基站都可以接收到来自动物4的定位信号,则定位服务器可以根据来自第一蓝牙定位基站、第二蓝牙定位基站和第三蓝牙定位基站的第一定位数据,确定动物4的位置信息。
应理解,本申请实施例仅以定位服务器根据第一蓝牙定位基站发送的第一定位数据确定目标物体的位置信息为例进行说明的,但本申请实施例的范围并不限于此。
还应理解,上文提到的定位服务器根据第一定位数据确定目标物体的位置信息可以理解为:第一蓝牙定位基站向MESH网关发送第一定位数据,MESH网关接收到第一定位数据后,可以对第一定位数据进行一定的处理以得到第二定位数据;或者,也可以不对第一定位数据进行处理,此时,第一定位数据可以与第二定位数据相同。之后,MESH网关通过蜂窝移动通信网 络向定位服务器发送第二定位数据,定位服务器接收到第二定位数据后,根据第二定位数据确定目标物体的位置信息。
如果只有一个蓝牙定位基站接收到了目标物体的定位信号,那么定位服务器可以粗略确定目标物体的位置信息。定位服务器根据来自多个蓝牙定位基站的第一定位数据,对目标物体进行定位。如此,可以实现对目标物体的精确定位。
应理解,上文提到的来自若干个蓝牙定位基站的具有同样时间戳的第一定位数据并不表示来自若干个蓝牙定位基站的第一定位数据的时间戳绝对相同,时间戳可以允许一定范围内的偏差。
定位服务器确定了目标物体的位置信息后,可以向电子设备向发送目标物体的位置信息,这样的话,用户可以从电子设备上访问目标物体的位置信息。
作为示例而非限定,本申请实施例中的电子设备可以为终端设备、手机、平板电脑、笔记本电脑、台式机电脑、游戏设备、车载电子设备或穿戴式智能设备等便携式或移动计算设备,以及电子数据库、汽车、银行自动柜员机(Automated Teller Machine,ATM)等其他电子设备。该穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或部分的功能,例如:智能手表或智能眼镜等,以及只专注于某一类应用功能,需要和其它设备如智能手机配合使用,如各类进行体征监测的智能手环、智能首饰等设备。
下面以目标物体为动物2为例,结合具体的实施例详细描述本申请实施例的技术方案。
步骤1:组网
a)用户根据需要覆盖的跟踪区域布置MESH网关和三个蓝牙定位基站。其中,该三个蓝牙定位基站分别为:第一蓝牙定位基站、第二蓝牙定位基站和第三蓝牙定位基站,该三个蓝牙定位基站可以组成一个MESH网络。
可选地,用户根据需要覆盖的跟踪区域布置MESH网关和三个蓝牙定位基站,可以包括:用户根据需要覆盖的跟踪区域的大小、地形和环境中的至少一个因素,布置MESH网关和三个蓝牙定位基站。
b)用户测试该三个蓝牙定位基站是否可以将数据发送到MESH网关。若该三个蓝牙定位基站的数据都可以发送到MESH网关,则固定该三个蓝牙定位基站和MESH网关的位置;若该三个蓝牙定位基站不能将数据发送到 MESH网关,则重新布置蓝牙定位基站的位置和/或MESH网关的位置,直到该三个蓝牙定位基站都可以将数据发送到MESH网关。
c)用户在分别固定了这三个蓝牙定位基站的位置后,可以分别测量这三蓝牙定位基站在地理坐标系中的坐标,并将各自的坐标值存储在定位服务器中。
d)MESH网络建立完成后,各蓝牙定位基站与MESH网关完成局域时间同步。
步骤2:定位
第一蓝牙定位基站接收到定位指令后,获取定位数据。其中,该定位数据包括动物2与第一蓝牙定位基站之间的RSSI和信号接收角度。第一蓝牙定位基站不在本地计算RSSI和信号接收角度,而是直接将RSSI、信号接收角度、动物2的编号、第一蓝牙定位基站的编号、局域时间戳组包,得到第一定位数据,并将第一定位数据发送给MESH网关。
步骤3:定位数据传输与处理
MESH网关接收到第一定位数据后,可以将局域时间的起始时间对应的世界标准时间组包得到第二定位数据,并通过蜂窝移动通信网络将第二定位数据发送给定位服务器。
如果MESH网关未成功向定位服务器发送第二定位数据,则MESH网关可以保存第二定位数据,并在第一时间内重新向定位服务器发送第二定位数据。
定位服务器接收到第二定位数据后的行为可以包括:
a)根据RSSI和信号接收角度计算动物2和第一蓝牙定位基站的相对坐标。
b)基于计算出的动物2与第一蓝牙定位基站的相对坐标,并结合第一蓝牙定位基站在地理坐标系中的坐标,确定动物2在地理坐标系中的坐标。
c)根据第二定位数据中的局域时间戳与局域时间的起始时间对应的世界标准时间,确定第一蓝牙定位基站发送定位数据的世界标准时间戳。
之后,定位服务器将动物2的位置信息以及该位置信息对应的世界标准时间戳,发送给电子设备。
本申请实施例采用BLE的MESH网络与蜂窝移动通信网络结合的方式对目标物体进行定位,蓝牙定位基站通过MESH网络将定位数据发送到 MESH网关,再由MESH网关将定位数据通过蜂窝移动通信网络发送到定位服务器。由于一个定位系统最少可以配置一个MESH网关,一个BLE模块可以与一个蜂窝移动通信模块组合为一个MESH网关,这样可以不用给每个目标物体都安装蜂窝移动通信模块,从而可以有效降低成本,适合大规模部署。此外,每座蓝牙定位基站可以覆盖半径数百米~2千米的范围,因此,可以使用少量的蓝牙定位基站就可以覆盖数平方公里的范围,有利于降低建设成本与维护成本。
进一步地,蓝牙定位基站可以依靠电池、太阳能和风力供电,从而可以持续工作数年。此外,基于GPS的定位方式的定位精度最高为10米,在有阻挡物的野外地形,定位精度可以下降到100米,MESH网络的定位精度最高可以达到厘米级,从而可以实现高精度定位。
在本申请实施例中,上述各过程的序号的大小并不意味着执行顺序的先后,各过程的执行顺序应以其功能和内在逻辑确定,而不应对本申请实施例的实施过程构成任何限定。
并且,在不冲突的前提下,本申请描述的各个实施例和/或各个实施例中的技术特征可以任意的相互组合,组合之后得到的技术方案也应落入本申请的保护范围。
