The slower the user's moving speed, the larger the preset second time interval or the preset rotation angle interval, and the smaller the ranging frequency.
- the positioning device may be provided with a sensor capable of detecting the rotation angle, such as a gyroscope/magnetometer.

为使本申请的上述目的、特征和优点能够更加明显易懂,下面结合附图和具体实施方式对本申请作进一步详细的说明。
参照图1,示出了本申请的一种定位方法实施例一的步骤流程图,该方法可应用于定位设备,定位设备设有第一LoRa测距装置,被定位对象具有第二LoRa测距装置,所述方法具体可以包括如下步骤:
步骤101,所述定位设备获取地图数据;
物联网技术是继计算机和互联网之后的第三次信息技术革命,具有实时性和交互性等优点,已经被广泛应用于城市管理、数字家庭、定位导航、物流管理、安保系统等多个领域。其中,LoRa是物联网中一种基于扩频技术的超远距离传输方案,具有传输距离远、低功耗、多节点和低成本等特性,定位是LoRa网络的重要应用。
本申请实施例的定位方法可以用于室内和室外的点对点定位。被定位对象可以是动物(包括人和宠物)或物体。
在用户需要定位时,用户可以向定位设备输入定位请求。定位设备可以响应定位请求,确定被定位对象。具体的,定位请求中可以包括被定位对象的标识信息,定位设备可以根据标识信息确定相应的被定位对象。
在本申请实施例中,提供一种用户可以采用定位设备对被定位对象进行定位的方式,定位设备可以获取地图数据,以在地图数据的界面上指示用户寻找被定位对象。
步骤102,所述定位设备通过所述第一LoRa测距装置与所述被定位对象的第二LoRa测距装置进行通信,并根据通信结果确定针对所述被定位对象的测距信息;
在本申请实施例中,定位设备可以设置有第一LoRa测距装置,被定位对象可以设置有第二LoRa测距装置,第一LoRa测距装置和第二LoRa测距装置可以相互通信,定位设备可以根据通信结果获得两者之间的测距信息。
测距信息可以包括距离与信号特征(如信号强度),测距信息还可以包括根据距离或信号特征的计算信息。例如,“距离远”、“距离近”、“信号强度:强”、“信号 强度:中”、“信号强度:弱”。
其中,定位设备可以为自带LoRa测距装置的移动终端,或者外接LoRa测距装置的移动终端。
具体的,定位设备的第一LoRa测距装置可以向被定位对象的第二LoRa测距装置发送测距请求无线帧;被定位对象的第二LoRa测距装置在接收到测距请求无线帧后,可以向定位设备的第一LoRa测距装置返回测距响应无线帧。
定位设备可以根据测距请求无线帧和测距响应无线帧,计算两者的距离值,以及确定测距响应无线帧的RSSI(Received Signal Strength Indication,接收的信号强度指示)。
步骤103,所述定位设备采用所述针对所述被定位对象的测距信息,确定所述被定位对象的目标位置;
具体的,定位设备可以记录在获取测距信息时的地理位置,根据多个地理位置以及相应的与被定位对象的距离,确定被定位对象的目标位置。
在平面定位中,至少需要在3个地理位置获得与被定位对象的距离,才能确定被定位对象的目标位置。在立体定位中,至少需要在4个地理位置获得与被定位对象的距离,才能确定被定位对象的目标位置。
在本申请实施例中,在大于预设数目的地理位置获得与被定位对象的距离时,可以采用获取到的全部地理位置以及相应的距离进行一次定位计算,也可以只选择预设数目的地理位置以及相应的距离分别进行定位计算。例如,在6个地理位置获得与被定位对象的距离时,可以采用6个地理位置以及相应的距离来进行一次定位计算,也可以只采用其中的5个地理位置以及相应的距离,按照不同的组合方式来进行定位计算。在实际中,所使用的地理位置和距离越多,定位的精准度越高。
被定位对象的目标位置可以采用定位算法计算得到,例如,在有3个第二地理位置时,可以采用三边测距定位算法;在有4个第二地理位置时,可以采用四边测距定位算法。定位算法的共性是根据多个地理位置,以及在各个地理位置测量的距离来进行定位。本领域技术人员可以根据实际的地理位置的数目来选择所需要的定位算法。
在实际中,LoRa测距装置的通信距离可能大于有效测距距离,例如,LoRa测距装置的通信距离可以达到2公里,但有效测距距离是500米。因此,本申请实施例中,定位设备可以通过测距信息判断被定位设备是否在有效测距距离内。当被定位对象在有测距距离内时,定位设备才通过定位算法精确计算被定位对象的位置。
步骤104,所述定位设备展示所述地图数据的界面,并根据所述目标位置信息在所 述界面上展示位置指示区域。
定位设备可以展示地图数据的界面。具体的,定位设备可以自带地图应用程序,或者调用第三方地图应用程序,通过地图应用程序获取地图数据并展示地图数据的界面。
在地图数据的界面展示有位置指示区域,位置指示区域是根据目标位置信息确定的一个区域,例如,若目标位置信息为一个具体坐标,则位置指示区域可以是以该区域为圆心的圆形区域。若目标位置信息为一个坐标范围,则可以以该坐标范围作为位置指示区域。
参照图2所示为本申请实施例中一种地图数据的界面示意图。在地图数据的界面包括形状为圆形的位置指示区域20。位置指示区域的形状除了可以是圆形外,还可以是正方形、六边形等各种形状,本申请对此不做限定。
本申请实施例中,通过获取地图数据;确定被定位对象的目标位置;展示地图数据的界面,并根据目标位置信息在界面上展示位置指示区域。使得用户可以在查看地图数据的界面时,可以根据位置指示区域,找寻到被定位对象,整个过程操作简单,方便用户查找被定位对象。
在本申请实施例中,定位设备还可以确定被定位对象的目标位置相应的定位误差;并且在地图数据的界面展示所述定位误差。
在一种示例中,可以以所述位置指示区域的面积大小表示相应的定位误差。例如,面积越大越大,表示定位误差越大。如图2所示,位置指示区域的圆形面积可以表示相应的定位误差。
在另一种示例中,可以以所述位置指示区域的颜色表示相应的定位误差。例如,位置指示区域为红色,则可以表示定位误差大;位置指示区域为绿色,则可以表示定位误差小。
在实际中,定位设备可以同时确定到多个目标位置信息,因此,在地图数据的界面可以同时展示多个位置指示区域。多个目标位置信息各自对应有定位误差,在一种示例中,在地图数据的界面上,可以只展示定位误差较小的目标位置信息对应的位置指示区域。随着用户的移动,展示在地图数据的界面的位置指示区域的个数、位置、定位误差都可能发生变化。
在本申请实施例中,定位设备还可以确定当前的朝向信息;并在地图数据的界面展示定位设备当前的朝向信息。通过展示定位设备当前的朝向信息,可以使得用户更好的选择行进方向。
在本申请实施例中,定位设备还可以展示测距信息。
参照图3所示为本申请实施例中一种展示测距信息的示意图。图3中移动描述指示图为柱状图,柱状图的每一柱形可以一个测距信息,柱形的长度可以表示测距信息的大小,并且测距信息可以展示在柱形之上。每个新的测距信息的柱形都出现在前一个测距信息的柱形边缘,比如最右边或最左边、最上侧或最下侧。当然,本领域技术人员还可以采用其他可以表示连续变化量的图作为移动定位指示图,例如曲线图,本申请实施例对比不做限定。
在一种示例中,定位设备可以在地图数据的界面展示测距信息,通过测距信息指导用户在走动的过程中找到被定位对象。
测距信息可以包括距离与信号特征(如信号强度),测距信息还可以包括根据距离或信号特征计算的信息。例如,“距离远”、“距离近”、“信号强度:强”、“信号强度:中”、“信号强度:弱”。
在本申请实施例中,定位设备能够提供两种定位模式包括:移动定位模式和定点定位模式。
在移动定位模式下,定位设备在移动时通过第一LoRa测距装置与被定位对象的第二LoRa测距装置进行通信,根据通信结果确定针对被定位对象的测距信息,并且可以在地图数据的界面展示测距信息。
具体的,定位设备在移动时,可以按照预设第一时间间隔或预设移动距离间隔,通过第一LoRa测距装置与被定位对象的第二LoRa测距装置进行通信,根据通信结果确定针对被定位对象的测距信息。
例如,定位设备在移动的过程中,每隔10秒与被定位对象通信一次,确定测距信息,或者,定位设备每移动10米就与被定位对象通信一次,确定测距信息。
其中,预设第一时间间隔或预设移动距离间隔可以由用户调整,也可以由定位设备根据用户的移动速度来调整。例如,用户的移动速度越快,预设第一时间间隔或预设移动距离间隔越小,测距频率越大。用户的移动速度越慢,预设第一时间间隔或预设移动距离间隔越大,测距频率越小。
在本申请实施例中,定位设备可以根据测距信息生成提示信息,并展示提示信息。例如,若信号强度弱,则可以生成“请四处走动,寻找信号强度的位置”的提示信息,以提示用户在移动定位模式下四处走动。
又例如,若信号强度强,则可以生成“已到达被定位对象附近,请四处张望,寻找 被定位对象。”,以提示用户注意观察被定位对象。
在移动定位模式下,定位设备还可以确定定位设备自身的移动轨迹,并在地图数据的界面展示移动轨迹。
参照图4所示为本申请实施例中另一种地图数据的界面示意图。图中,包括位置指示区域40、移动轨迹41,以及定位设备当前的朝向信息42。
在一种示例中,定位设备可以在移动轨迹的不同位置上以可区别展示的内容表示不同位置相应的测距信息。其中,可区别展示的内容包括但不限于图形、符号、数字、文字、颜色、面积、长度等形式,以及这些形式的组合。例如,颜色越深,表示测距信息越大;面积越大,表示测距信息越大;长度越大,表示测距信息越大。
参照图5所示为本申请实施例中不同形式的移动轨迹的示意图。图中,移动轨迹形式1为单一颜色的直线段;移动轨迹形式2为多种颜色混合的直线段;移动轨迹形式3为由螺旋条纹过度到直线的线段;移动轨迹形式4为由多个不同大小的圆形依次排列;移动轨迹形式5为由多个不同长度的线段依次排列。
在定点定位模式下,定位设备在定点转动的过程中,采用第一LoRa测距装置与被定位对象的第二LoRa测距装置进行通信,根据通信结果确定针对被定位对象的多个测距信息。
具体的,定位设备在定点转动的过程中,按照预设第二时间间隔或预设转动角度间隔,采用第一LoRa测距装置与被定位对象的第二LoRa测距装置进行通信,根据通信结果确定针对被定位对象的多个测距信息。
例如,在定位设备定点转动时,每隔2秒与被定位对象进行一次通信,根据通信结果确定测距信息,或者,定位设备每转动15度就与被定位对象进行通信,根据通信结果确定测距信息。
其中,预设第二时间间隔或预设转动角度间隔可以由用户调整,也可以由定位设备根据用户的移动速度来调整。例如,用户的移动速度越快,预设第二时间间隔或预设转动角度间隔越小,测距频率越大。用户的移动速度越慢,预设第二时间间隔或预设转动角度间隔越大,测距频率越小。
定位设备可以设置有陀螺仪/磁力计等能检测转动角度的传感器。
在本申请实施例中,定位设备可以在定点转动过程中获得测距信息时,确定对应的转动角度。定位设备在地图数据的界面上展示测距信息的同时,还可以展示测距信息对应的转动角度。
参照图6所示为本申请实施例中又一种地图数据的界面示意图。图中,地图数据的界面展示有位置指示区域60和定点定位指示图61,定点定位指示图61包括一圆环,圆环的角度可以表示定位设备的转动角度。在圆环的不同角度上可以展示相应的测距信息,也可以不展示相应的测距信息。定点定位指示图中,还可以展示有定位设备当前的朝向信息62、相对方向信息63以及上一次定点定位测得的测距信息64。
在本申请实施例中,在本申请实施例中,定位设备可以确定定位设备的当前位置,并确定当前位置相对目标位置的相对方向信息;在地图数据的界面展示相对方向信息,以指示用户行进。其中,相对方向信息可以是从当前位置指向目标位置的方向指示。
在本申请实施例中,定位设备可以提示用户需要在定点定位模式下,对其他角度进行测距。例如,“请回到提示点,换一个方向走”,“请在当前位置,按照向提示方向进程测距”。
在定点定位指示图中可以同时显示已获得测距信息的转动角度(也就是在显示在圆周上的点)和需要用户测距的转动角度(也就是在显示在圆周上的点)。已测距的转动角度的点和需要用户测距的转动角度的点可以采用不同形式来区分。例如,以不同的形状、大小、颜色来区分。
一旦用户根据提示信息,将定位设备转动到需要测距的转动角度进行测距,则定位设备可以将该转动角度的点从需要测距的形式转换为已定位的形式。
在本申请实施例中,定位设备可以判断在某一角度的测距是否成功。具体的,定位设备可以确定向被定位对象发送测距请求无线帧时的第一角度和接收到测距响应无线帧时的第二角度;判读第一角度和第二角度的差值是否小于预设角度阈值,若是,则认为在第一角度测距成功。预设角度阈值可以根据实际情况设定,例如1度、2度、5度等等。
在本申请的一种实施例中,定位设备可以设定安全区域,当被定位对象不在安全区域内时,定位设备可以执行预设提醒操作。执行预设提醒操作可以是蜂鸣、闪烁、发出提醒消息、震动的方式。
安全区域可以是一个绝对区域,例如,由具体坐标确定的区域。安全区域也可以是一个相对区域,例如,安全区域可以是定位设备自身的位置为中心,半径为设定长度的圆形区域。
在本示例中,设定的安全区域具有时效性,定位设备可以设定安全区域在设定的时间内有效,当设定超时,则撤销安全区域。例如,在启用安全区域后的一个小时内,安全区域有效。
在本示例中,安全区域可以设定多个,不同的安全区域可以分别对应不同的提醒操作。例如,定位设备同时设定第一安全区域和第二安全区域,第一安全区域是以定位设备为中心,半径为50米的圆形区域。第二安全区域是以定位设备为中心,半径为100米的圆形区域。当被定位对象,不在第一安全区域,还在第二安全区域时,定位设备可以发出蜂鸣。当被定位对象,不在第一安全区域,也不在第二安全区域时,定位设备可以发出蜂鸣,同时还可以闪烁。通过设定安全区域,可以更好的避免被定位对象丢失。例如,在携带行李时,希望行李不离开自身2米。又例如,不希望小孩离开自己20米。
在本申请的一种实施例中,定位设备可以设定禁入区域,当被定位对象位于禁入区域时,定位设备可以执行预设提醒操作。
禁入区域可以是一个绝对区域,例如,由具体坐标确定的区域。禁入区域也可以是一个相对区域,例如,禁入区域可以是超出以定位设备自身的位置为中心半径为设定长度的圆形区域的区域。
在本示例中,设定的禁入区域具有时效性,定位设备可以设定禁入区域在设定的时间内有效,当设定超时,则撤销禁入区域。例如,在启用禁入区域后的一个小时内,禁入区域有效。
在本示例中,禁入区域可以设定多个,不同的禁入区域可以分别对应不同的提醒操作。
通过设定禁入区域,可以更好的监控被定位对象。例如,不希望宠物走进家里的某个房间。
