具体实施方式
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,具体可以包括如下步骤:
步骤101,定位设备确定当前定位模式为移动定位模式或定点定位模式;
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,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)。
定位设备的定位模式包括移动定位模式和定点定位模式。
步骤102,在移动定位模式下,所述定位设备在移动时采用所述第一LoRa测距装置与所述第二LoRa测距装置进行通信,根据通信结果确定针对所述被定位对象的多个测距信息,并在移动定位指示图中依次展示所述多个测距信息;
在移动定位模式下,定位设备可以在移动的过程中对被定位对象发起测距,从而获得针对被定位对象的测距信息,并且定位设备会生成并展示移动定位指示图,在移动定位指示图中还可以依次展示各个测距信息。
在本申请实施例中,所述定位设备在移动时采用所述第一LoRa测距装置与所述第二LoRa测距装置进行通信的步骤具体可以包括:所述定位设备在移动时,按照预设第一时间间隔或预设移动距离间隔,采用所述第一LoRa测距装置与所述第二LoRa测距装置进行通信。
例如,定位设备在移动的过程中,每隔10秒测量一次与被定位对象的测距信息,或者,定位设备每移动10米就测量一次与被定位对象的测距信息。
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。
参照图2所示为本申请实施例中的移动定位指示图。图2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。
在本申请实施例中,在移动定位模式下,若获取到定点定位模式切换指令,或检测到定位设备在进行定点转动,则所述定位设备切换到所述定点定位模式。
在本申请实施例的一种示例中,在本申请实施例的一种示例中,定位设备在从移动定位模式切换到定点定位模式时,定位设备还可以清空定点定位指示图中原来的测距信息和相应转动角度。
具体的,在定位设备的展示界面可以提供定位模式切换开关,用户可以通过点击切换开关从而选择是进入移动定位模式还是定点定位模式。
步骤103,在定点定位模式下,所述定位设备在定点转动时采用所述第一LoRa测距装置与所述第二LoRa测距装置进行通信,根据通信结果确定针对所述被定位对象的多个测距信息,确定测距信息对应的转动角度,并在定点定位指示图中展示所述多个测距信息以及相应的转动角度。
在本申请实施例中,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。
在定点定位模式下,定位设备在定点转动的过程中对被定位对象发起测距,从而获得针对被定位对象的测距信息,并且定位设备会生成并展示定点定位指示图,在定点定位指示图中还展示各个测距信息以及相应的转动角度。
在本申请实施例中,所述定位设备在定点转动时采用所述第一LoRa测距装置与所述第二LoRa测距装置进行通信的步骤具体可以包括:所述定位设备在定点转动时,按照预设第二时间间隔或预设转动角度间隔,采用所述第一LoRa测距装置与所述第二LoRa测距装置进行通信。
例如,在定位设备定点转动时,每隔2秒测量一次与被定位对象的测距信息,或者,定位设备每转动15度就测量一次与被定位对象的测距信息。
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。
参照图3所示为本申请实施例中的定点定位指示图。定点定位指示图包括一个圆环,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。
在本申请实施例中,在定点定位模式下,若获取到移动定位模式切换指令,或检测到定位设备在进行移动,则所述定位设备切换到所述移动定位模式。
在本申请实施例的一种示例中,定位设备在从定点定位模式切换到移动定位模式时,定位设备可以清空定点定位指示图中原来的测距信息和相应转动角度。
在本申请实施例中,定位设备在定点定位模式下,可以根据多个测距信息以及相应的转动角度,确定被定位对象的方向信息;然后在定点定位指示图中展示被定位对象的方向信息。
其中,所述根据所述多个测距信息以及相应的转动角度,确定被定位对象的方向信息的步骤具体可以包括:定位设备确定多个弧度区间;计算各个弧度区间内的测距信息的平均值;将平均值最小的弧度区间的方向,确定为被定位对象的方向信息。
弧度区间可以以不同的角度为中心以及预设弧度范围确定,或者以不同的角度为起点以及预设弧度范围来确定。
例如,以0度、45度、90度……315度为中心,180度为弧度范围,确定多个弧度区间。又例如,以0度、45度、90度……315度为起点,180度为弧度范围,确定多个 弧度区间。
当然本领域技术人员还可以以其他方式来确定弧度区间,本申请对此不做限定。
假设,在定位设备定点转动时,在0/45/90/135/180/225/270/315这些转动角度测得的距离分别是:110/110/105/100/100/100/105/110米。
以0度起始的弧度区间内的距离的平均值为(110+110+105+100+100)/5=105;
以45度起始的弧度区间内的距离的平均值为(110+105+100+100+100)/5=103;
以90度起始的弧度区间内的距离的平均值为(105+100+100+100+105)/5=102;
……
假如以90度起始的弧度区间内的距离的平均值最小,则将以90度起始的弧度区间的方向确定为被定位对象的方向信息。
图3中,定点定位指示图上还包括以黑色弧形表示的被定位对象的方向信息。除了以弧形表示被定位对象的方向信息外,还可以用一个或多个点、一个或多个箭头、一个或多个色块、或形式的图形来指示被定位对象的方向信息。
在本申请实施例中,定位设备还可以在定点定位模式下,确定定位设备当前的朝向信息;并且在定点定位指示图中展示定位设备当前的朝向信息,从而可以提示用户可以往哪个方向前进。图3中,定点定位指示图上还包括以箭头形式表示的定位设备当前的朝向信息。
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。
在本申请实施例中,定位设备提供移动定位模式和定点定位模式供用户选择,在移动定位模式通过移动定位指示图展示测距信息,在定点定位模式通过定点定位指示图展示测距信息,通过测距信息指导用户在走动的过程中找到被定位对象。整个定位方式不依赖GPS和基站的辅助,并且操作简单,方便用户查找被定位对象。
在实际中,用户在使用移动定位模式时,测距信息可能不会变小或变大,测距信息变小,表示与被定位对象的距离在变小;测距信息变大,表示与被定位对象的距离在变大。当用户发现,距离测距信息越来越大时,用户可以切换到定点定位模式,在定点定位模式下,用户可以拿着定位设备原地转动,测定在不同方向(转动角度)的测距信息,在获得多个角度的测距信息后,用户可以选择测距信息最小的方向进行移动,同时使定位设备切换至移动定位模式,重复上述过程,用户可以在移动定位模式和定点定位模式之间不断切换,从而不断接近被定位对象。
在本申请实施例中,定位设备可以采用测距信息,确定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。
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。
