为了使本技术领域的人员更好地理解本说明书一个或多个实施例中的技术方案，下面将结合本说明书一个或多个实施例中的附图，对本说明书一个或多个实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是一部分实施例，而不是全部的实施例。基于本说明书一个或多个实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都应当属于本公开保护的范围。
随着共享车辆(例如，共享单车、共享电动车)的使用数量的增多，有些地方为车辆划分了多个停车区域，车辆的使用者在结束使用后可以将车辆停在该停车区域中，以避免乱停乱放影响生活管理。例如，可以在地铁口设置一块专用于共享车辆停放的停车区域，或者在生活小区的门口划出一块共享车辆停车区域，或者在办公场所的室外道路上划分一块停车区域。
而对于共享车辆的管理者来说，共享车辆是否按照规定停放在停车区域，需要进行了解和制定进一步的管理策略。本说明书一个或多个实施例提供的车辆定位方法，可以帮助管理者更加准确的确定共享车辆是否停放在停车区域。此外，由于通过停车区域对 共享车辆的停放进行了约束，可以将停车区域形象的称为“电子围栏”，以约束共享车辆的使用者将车辆停放到该围栏对应的区域内。而本公开的车辆定位方法可以是通过电子围栏***实现车辆定位。
图1示例了一个电子围栏***的实现结构，如图1所示，该电子围栏***可以包括三个设备：信号发射装置11、车辆定位设备12和车辆管理装置13。
其中，信号发射装置11可以设置在共享车辆上，图1中以共享单车为例，可以理解的是，共享电动车、共享汽车等其他车辆也可以适用于该***。在一个例子中，该信号发射装置11可以是用于发射蓝牙信号的蓝牙信号发射装置，以用于根据蓝牙信号对共享单车进行蓝牙定位。在采用其他近距离定位方式(例如，超宽带技术(UWB，Ultra Wide Band)技术、ZigBee)的例子中，信号发射装置11还可以是发射其他近距离定位信号的装置，本例子以蓝牙定位为例来描述。
该信号发射装置11可以广播两种数据，一种数据是共享单车的车辆标识即唯一标识车辆的车辆ID，另一种数据是蓝牙信号。上述两种数据的广播可以是周期性广播，或者也可以是在共享单车锁车的时候出发数据的广播。
其中，车辆定位设备12可以设置在用于停放车辆的停车区域，该停车区域具有自己的区域标识，停放在该区域的车辆并不限制，例如，用车的用户恰好在某个停车区域结束用车，则将车辆停放在该停车区域即可。
该车辆定位设备12可以用于接收信号发射装置11发送的车辆标识和蓝牙信号，并且还可以根据蓝牙信号利用蓝牙定位算法对车辆进行定位运算，得到车辆的位置信息。在一个例子中，该位置信息可以是共享单车与车辆定位设备12之间的距离。接着，车辆定位设备12还可以将自己所在的停车区域的区域标识、车辆的车辆标识以及计算得到的车辆位置信息，发送至车辆管理装置13。
如图1的示例，车辆管理装置13可以设置在云端。在其他的例子中，车辆管理装置13也可以设置在其他位置。该车辆管理装置13可以根据车辆定位设备12发送的位置信息，确定所述车辆标识对应的车辆是否停车在所述区域标识对应的停车区域。例如，如果位置信息是车辆与车辆定位设备12之间的距离，那么假如该距离在预定的距离阈值范围内，则可以确定车辆停放在停车区域中。
本说明书一个或多个实施例的车辆定位方法，可以通过上述图1示例的电子围栏***实现对车辆停放的定位，判断车辆是否停放在预定的停车区域。如下通过图2所示的 流程图，描述该定位方法的执行过程。
在步骤200中，共享单车上的信号发射装置广播数据。
本例子的方法以图1中的共享单车为例进行描述，但并不局限于此。共享单车可以是通过手机扫码开始骑行和计费的互联网自行车。共享单车上可以设置一个信号发射装置，该装置可以发射近距离定位信号，例如可以是蓝牙信号。在其他的例子中，信号发射装置还可以发射UWB等信号用于车辆定位。
信号发射装置可以是在用户触发停车动作时广播数据，例如，用户结束用车后，可以通过关锁等行为，触发共享单车进入关锁状态，此时信号发射装置开始广播数据。广播的数据中可以包括唯一标识车辆的车辆标识，后续云端的车辆管理装置可以通过该车辆标识识别到对应的车辆；广播的数据中还可以包括蓝牙信号。如果用户停车的附近有停车区域(可以称为电子围栏)，则该蓝牙信号可以被停车区域内的车辆定位设备接收并据此识别车辆是否停在停车区域内；否则，如果停车附近没有停车区域，云端可以认为本次停车属于随意停车。
在步骤202中，停车区域的车辆定位设备根据定位信号对车辆进行定位运算，得到所述车辆的位置信息。
本例子中，可以利用蓝牙定位算法对共享单车进行定位运算，该算法是通过接收蓝牙信号的车辆定位设备感知信号强弱来获知被测量的共享单车的距离，以实现定位。例如，车辆定位设备可以测量所接收到的蓝牙信号的接收信号强度，并根据该接收信号强度，利用蓝牙定位算法对车辆进行定位运算，得到车辆与车辆定位设备之间的距离。通常接收信号越强，表明车辆离停车区域越近。
其中，车辆定位设备中的用于接收蓝牙信号的信号接收模块可以设置至少一个。示例性的，可以设置三个信号接收模块，以通过三点定位算法更加准确的定位共享单车的位置，精确度可以在3～5米的范围内。
在步骤204中，停车区域的车辆定位设备将位置信息发送至车辆管理装置。
本步骤中，车辆定位设备可以将停车区域的区域标识、共享单车的车辆标识以及在步骤202中计算得到的位置信息，发送至云端的车辆管理装置。上述的区域标识可以是用于唯一标识所述停车区域的信息，例如可以是停车区域的经纬度等地理位置信息，或者还可以是停车区域的ID。
在本说明书一个或多个例子中，位置信息可以是共享单车与车辆定位设备之间的距 离。在其他例子中，位置信息也可以是确定单车是否停放在停车区域的判断结果。在将上述信息发送至云端的车辆管理装置后，车辆管理装置可以进行停车管理以及进一步的业务行为，例如，奖励停车在停车区域内的单车，或者惩罚停车不在停车区域的行为，详见后续步骤。
在步骤206中，云端的车辆管理装置判断共享单车是否停放在停车区域。
本步骤中，车辆管理装置可以根据接收到的区域标识，获取该区域标识对应的距离阈值。不同的区域标识对应的停车区域，距离阈值可能不同，例如，在地铁口附近的停车区域，通常使用共享单车的需求更大，停放的共享单车比较多，所以这个停车区域的面积也较大，距离阈值可以设置较大一些。又例如，居民小区门口的停车区域可以相对较小，所以距离阈值可以设置稍小一些。
云端可以存储各个停车区域的区域标识与距离阈值的对应关系，根据该对应关系获取到对应某个区域标识的距离阈值。车辆管理装置可以将接收到的车辆与车辆定位设备之间的距离与该距离阈值进行比较，若距离在距离阈值的范围内，则可以确定车辆标识对应的共享单车停在区域标识对应的停车区域中。
在步骤208中，云端的车辆管理装置根据车辆的定位进行对应的业务处理。
例如，车辆管理装置可以根据车辆是否停放在停车区域，来对车辆使用者进行相应的奖励或者惩罚。比如，停放在停车区域的共享单车，可以给用户反馈奖励、红包，没有停放在停车区域内的单车则没有奖励活动。
本例子的车辆定位方法，通过在车辆上安装用于发射近距离定位信号的发射装置，并且与设置在停车区域的车辆定位设备相配合，实现对车辆的近距离定位，可以使得对车辆的定位精度更高，更准确的实现车辆定位；并且，在采用蓝牙定位方式时，可以使得功耗较低。该方法可以帮助共享车辆运营者约束车辆使用者将车辆停放到指定的停车区域内，解决了共享车辆乱停乱放的问题。
为了实现上述的车辆定位方法，本说明书一个或多个实施例还提供了一种车辆定位设备。该车辆定位设备可以是设置在用于停放车辆的停车区域内，如图3所示，该车辆定位设备可以包括：信号接收模块31、定位运算模块32和网络收发模块33。
