具体实施方式
以下基于实施例对本说明书进行描述,但是本说明书并不仅仅限于这些实施例。在下文对本说明书的细节描述中,详尽描述了一些特定的细节部分。对本领域技术人员来说没有这些细节部分的描述也可以完全理解本说明书。为了避免混淆本说明书的实质,公知的方法、过程、流程、元件和电路并没有详细叙述。
此外,本领域普通技术人员应当理解,在此提供的附图都是为了说明的目的,并且附图不一定是按比例绘制的。
除非上下文明确要求,否则在说明书的“包括”、“包含”等类似词语应当解释为包含的含义而不是排他或穷举的含义;也就是说,是“包括但不限于”的含义。
在本说明书的描述中,需要理解的是,术语“第一”、“第二”等仅用于描述目的,而不能理解为指示或暗示相对重要性。此外,在本说明书的描述中,除非另有说明,“多个”的含义是两个或两个以上。
目前,司机端或者乘客端的定位一般基于卫星定位技术,但是,当终端设备处于卫星信号微弱的地方时(例如地下室等),会使得司机端或者乘客端的定位不准确,进而导致司 机与乘客无法准确的确定对方的位置。
为了解决在卫星信号微弱的场景中,司机与乘客无法准确的确定对方位置的问题,本说明书实施例提供一种定位系统,如图1所示,该系统包括:第一设备1和第二设备2。
其中,第一设备1和第二设备2可以是智能手机、平板电脑或者个人计算机(Personal Computer,PC)等,虚线的圆形范围用于表征以第一设备1为中心的预设范围,在本说明书实施例中,该预设范围用于表征可以建立短距离无线通信连接的范围。
当第二设备2与第一设备1之间的距离A小于该预设范围的半径时,即第二设备2进入该预设范围时,第一设备1可以尝试与第二设备2建立短距离无线通信连接,其中,距离A可以是根据第一设备1和第二设备2最近一次卫星定位数据确定的距离。
例如,第一设备1可以为乘客所持有的智能手机1,第二设备2可以为网约车司机所持有的智能手机2,在一个实际应用场景中,乘客(智能手机1)处于地下停车场(地下停车场的卫星信号微弱),网约车司机(智能手机2)驾驶车辆从远处驶向乘客所处的地下停车场。
当智能手机2对应的卫星定位点处于预设范围内时(例如预设范围可以是以智能手机1为圆心,半径100米的范围),表征智能手机2可能已经进入地下停车场,此时,智能手机1可以周期性的向智能手机2发送短距离无线通信连接建立请求,以建立短距离无线通信连接。
在另一个实际应用场景中,乘客同样处于地下停车场,网约车司机驾驶车辆从远处驶向乘客所处的地下停车场。
当智能手机2对应的卫星定位点处于预设范围内时(例如预设范围可以是以智能手机1为圆心,半径150米的范围),表征智能手机2可能已经进入地下停车场,此时,智能手机2可以周期性的向智能手机1发送短距离无线通信连接建立请求,以建立短距离无线通信连接。
再例如,第一设备1可以为网约车司机所持有的智能手机3,第二设备2可以为乘客所持有的智能手机4,在一个实际应用场景中,乘客(智能手机4)处于地下停车场,网约车司机(智能手机3)驾驶车辆从远处驶向乘客所处的地下停车场。
当智能手机4对应的卫星定位点处于预设范围内时(例如预设范围可以是以智能手机3为圆心,半径100米的范围),表征网约车司机与乘客的距离很小,进而,智能手机3可以周期性的向智能手机4发送短距离无线通信连接建立请求,以建立短距离无线通信连接。
当第一设备1(智能手机1或3)和第二设备2(智能手机2或4)建立短距离无线通 信连接后,第一设备1和第二设备2可以基于该短距离无线通信连接确定二者之间的相对位置,以实现网约车司机和乘客可以快速找到对方的位置。
下面将结合具体实施方式,对本说明书实施例提供的一种基于超宽带的定位方法进行详细的说明,如图2所示,具体步骤如下:
在步骤100,响应于第二设备处于预设范围内,建立与第二设备的短距离无线通信连接。
在步骤200,接收第二设备发送的短距离信号。
在步骤300,基于短距离信号确定定位数据。
在步骤400,基于定位数据确定相对位置信息。
其中,相对位置信息用于表征第一设备和第二设备的相对位置。
在步骤500,展示相对位置信息。
在本说明书实施例中,由于短距离无线通信连接不易受到干扰,所以第一设备与第二设备可以基于短距离无线通信连接确定一个准确的相对位置,当第一设备或者第二设备所对应的绝对位置不准确时(例如通过卫星定位确定位置时,可能由于卫星信号微弱导致卫星定位点不准确),第一设备或者第二设备可以根据准确的相对位置确定对方所处的位置,在一个网约车的应用场景中,通过本说明书实施例可以实现网约车司机和乘客之间的快速互找。
更进一步的,针对步骤100,短距离无线通信连接可以是超宽带(Ultra Wide Band,UWB)连接,具体的,UWB是一种无线载波通信技术,它不采用正弦载波,而是利用纳秒级的非正弦波窄脉冲传输数据,因此其所占的频谱范围很宽,进而,基于其自身的性质,UWB具有数据传输速度高、功耗低以及定位精确等优点。
在本说明书实施例中,第一设备和第二设备可以包括UWB模块,进而,上述短距离无线通信连接可以基于第一设备和第二设备中的UWB模块建立。
结合上述步骤100至步骤500,本说明书实施例提供一种第一设备,以执行步骤100至步骤500,具体的,如图3所示,第一设备包括:短距离无线通信模块31、展示模块32以及控制器33;
其中,控制器33可以被配置为执行:响应于第二设备处于预设范围内,控制短距离无线通信模块31建立与第二设备的短距离无线通信连接;控制短距离无线通信模块31,接收第二设备发送的短距离信号;基于短距离信号确定定位数据;基于定位数据确定相对位置信息,其中,相对位置信息用于表征第一设备和第二设备的相对位置;以及控制展示模块32,展示相对位置信息。
也就是说,第一设备中的控制器33可以通过控制第一设备中的各个模块,以实现上述步骤100至步骤500。
在本说明书实施例中,由于短距离无线通信连接不易受到干扰,所以第一设备与第二设备可以基于短距离无线通信连接确定一个准确的相对位置,当第一设备或者第二设备所对应的绝对位置不准确时(例如通过卫星定位确定位置时,可能由于卫星信号微弱导致卫星定位点不准确),第一设备或者第二设备可以根据准确的相对位置确定对方所处的位置,在一个网约车的应用场景中,通过本说明书实施例可以实现网约车司机和乘客之间的快速互找。
短距离无线通信模块可以包括UWB模块311,第一设备可以基于UWB模块311与第二设备建立UWB连接,当然,短距离无线通信模块31中也可以包括其它无线通信模块,例如,短距离无线通信模块31中还可以包括蓝牙模块,第一设备可以基于蓝牙模块与第二设备建立蓝牙连接,以实现上述方法步骤。
当第一设备与第二设备建立短距离无线通信连接后,第一设备可以接收第二设备发送的短距离信号,然后根据该短距离信号确定定位数据,进而根据定位数据确定相对位置信息。
在一种可实施方式中,定位数据可以包括相位差和波长,相对位置信息可以包括角度信息,第一设备可以包括多个信号接收天线。
进一步的,第一设备中的控制器还可以被配置为执行:针对多个信号接收天线中任意两个信号接收天线,基于相位差、波长和两个信号接收天线之间的距离,确定角度信息。
其中,角度信息用于表征第二设备的信号发送方向与两个信号接收天线之间连线的夹角。
具体的,如图4所示,图4为本说明书实施例提供的一种角度信息确定过程的示意图,该示意图包括:天线1、天线2和信号A;
其中,天线1和天线2为安装在第一设备上的两个天线,信号A为第二设备发送的短距离信号(例如UWB信号),天线1与天线2之间的距离为d,天线1和天线2之间的连线与信号A的传播方向之间的夹角为θ。
在本说明书实施例中,θ可以用于表征第二设备相对于第一设备的角度,也就是说,θ即为上述角度信息。
具体的,θ的数值可以基于反三角函数进行计算确定,即θ=arccosθ,其中,arccosθ用于表征关于θ的余弦函数的反三角函数,并且,cosθ为需要求解的未知量。
进一步针对cosθ,cosθ=x/d,其中,x用于表征θ的临边,并且,x为需要求解的未知量。
进一步针对x,x=λ(Ψ/2π),其中,λ用于表征信号A的波长,Ψ用于表征相位差,由于λ和Ψ为根据信号A的基本属性获取的参数,因此,可以基于λ和Ψ确定x,进而,可以基于x确定cosθ,最终,可以基于cosθ确定arccosθ,也就是θ的数值。
在另一种可实施方式中,定位数据还包括时间戳信息,相对位置信息还包括相对距离信息。
进一步的,第一设备中的控制器还可以被配置为执行:基于时间戳信息确定相对距离信息,相对距离信息用于表征第一设备与第二设备之间的距离。
在实际应用中,第二设备在发送短距离信号时,可以在该短距离信号中加入时间戳信息,其中,时间戳可以用于表征信号发出的时刻,进而,第一设备可以基于光速和时间戳信息中的时刻,确定第一设备和第二设备之间的距离。
当第一设备确定角度信息和距离信息后,可以基于展示模块展示角度信息和距离信息,即第一设备中的控制器可以控制展示模块展示角度信息和距离信息。
在一种可实施方式中,第一设备可以在预设坐标系中基于角度信息和距离信息展示第二设备的位置,如图5所示,图5为预设坐标系的示意图,该示意图包括:用于表征第一设备位置的坐标点A和用于表征第二设备位置的坐标点B。
其中,在图5所示的坐标系中,半径用于表征坐标点距离坐标点A的距离,距离的单位为米,角度用于表征坐标点相对于坐标点A的方向,具体的,当第一设备确定相对位置信息后,可以基于相对位置信息中的角度信息和距离信息确定坐标点B的坐标,进而通过展示模块在预设坐标系中展示坐标点B,以使得网约车司机或者乘客可以基于第一设备展示的坐标点B快速找到对方的位置。
更进一步的,在一种可选的实现方式中,当第一设备确定相对位置信息后,还可以向第二设备发送相对位置信息,以使得第二设备展示相对位置信息,即第一设备中的控制器可以控制短距离无线通信模块,向第二设备发送相对位置信息。
当第二设备接收到相对位置信息后,可以基于相对位置信息建立关于第一设备位置的坐标系,也就是说,在第二设备所展示的坐标系中,坐标系的中心点为上述坐标点B。
进而,网约车司机或者乘客可以基于第二设备展示的坐标点A快速找到对方的位置,这样,当第二设备仅安装有一个天线时,可以基于该实现方式展示与第一设备的相对位置。
结合本说明书实施例提供的各实施方式,需要进一步说明的,本说明书实施例仅通过具体功能区别第一设备和第二设备,也就是说,第一设备既可以是乘客端对应的设备,也可以是司机端对应的设备。
在一种应用场景中,乘客端设备和司机端设备在进行短距离无线通信时,若乘客端设备和司机端设备中均安装有至少两个天线,则乘客端设备可以直接根据司机端设备发送的短距离信号确定相对位置信息,相应的,司机端设备也可以直接根据乘客端设备发送的短距离信号确定相对位置信息。
在乘客端设备根据司机端设备发送的短距离信号确定相对位置信息的过程中,乘客端设备为第一设备,司机端设备为第二设备。
在司机端设备根据乘客端设备发送的短距离信号确定相对位置信息的过程中,司机端设备为第一设备,乘客端设备为第二设备。
也就是说,在本场景中,乘客端设备即作为第一设备也作为第二设备,司机端设备同样即作为第一设备也作为第二设备。
在本说明书实施例中,由于短距离无线通信连接不易受到干扰,所以第一设备与第二设备可以基于短距离无线通信连接确定一个准确的相对位置,当第一设备或者第二设备所对应的绝对位置不准确时,第一设备或者第二设备可以根据准确的相对位置确定对方所处的位置。
