Description

车辆身份的识别方法、装置、主设备和从设备 技术领域
本说明书实施例涉及互联网技术领域，尤其涉及一种车辆身份的识别方法、装置、主设备和从设备。
背景技术
目前，针对车辆身份的自动识别，一般采用不停车电子收费系统(electronic toll collection，ETC)、车牌识别或蓝牙卡等方案实现。ETC通过安装在车辆挡风玻璃上的车载电子标签与收费站ETC车道上的微波天线之间的微波专用短程通讯，识别车辆身份，例如：车辆的车牌号码。但是，微波天线的成本较高，且部署麻烦，不适合在停车场等场景推广，普适性较差。车牌识别的方案，成本也比较高，并且雾天、光照和/或车牌污损等都会影响车牌识别的准确度。而蓝牙卡的方案，存在无法精准定位的问题，即存在跟车干扰和旁道干扰的问题，容易出现误扣车费的情况，例如，前车没有装蓝牙卡，而后车装了，扣了后车的钱，却让前车通行。因此，需要提供一种车辆身份的识别方案，既可以提高车辆识别的准确度和定位的精度，又具有较高的普适性。

具体实施方式
应当明确，所描述的实施例仅仅是本说明书一部分实施例，而不是全部的实施例。基于本说明书中的实施例，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它实施例，都属于本说明书保护的范围。
在本说明书实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本说明书。在本说明书实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。
现有相关技术中，针对车辆身份的自动识别，大多采用ETC、车牌识别或蓝牙卡等方案，这些方案各有缺点，如成本高、普适性较差、容易受到干扰或误识率高等。
因此，本说明书实施例提供一种车辆身份的识别方法，既可以提高车辆识别的准确度和定位的精度，又具有较高的普适性。
图1为本说明书车辆身份的识别方法一个实施例的流程图，如图1所示，上述车辆身份的识别方法可以包括：步骤102，主设备发送低频信号，上述低频信号的辐射范围是预先设定的。
其中，主设备是指主动发送低频信号的设备，与主设备对应的是从设备，从设备一般处于睡眠状态，其收到低频信号后，进行应答。
低频信号中，磁场信号占主导地位，低频信号的辐射范围容易控制(半径一般为3米)。因此可以通过控制主设备发出的低频信号的辐射范围，来与从设备进行通信。只有在辐射范围内的从设备，才能接收到低频信号，而在辐射范围外的从设备，将不会接收到低频信号，或者接收到的低频信号的信号强度很弱。
上述低频信号的辐射范围可以包括上述低频信号的辐射角度和辐射半径，本实施例中，主设备可以安装在路边某个固定位置，如图2所示，这时，从设备可以安装在车辆上。因此在具体实现时，可以根据主设备与需要检测的车道的相对位置，以及车道的宽度和/或车辆的长度等，设定低频信号的辐射角度和辐射半径，使得只有在主设备需要检测的车道内行驶的车辆上携带的从设备，才可以接收到上述低频信号。其中，图2为本说明书一个实施例提供的主设备和从设备的安装位置的示意图。
步骤104，接收从设备发送的针对上述低频信号的应答信号，上述应答信号是上述从设备接收到上述低频信号，并且检测到上述低频信号的信号强度大于或等于预定阈值之后发送的。
具体地，上述预定阈值可以在具体实现时，根据实现需求和/或系统性能等自行设定，本实施例对上述预定阈值的大小不作限定。
由于随距离增长，低频信号(主要是磁场信号)的信号强度迅速衰减，可以做到在3m外信号强度趋近于0，因此在预先设定低频信号的辐射范围之后，只有当携带从设备的车辆进入上述辐射范围，上述从设备才会由睡眠状态被唤醒。当从设备检测到上述低频信号的信号强度大于或等于预定阈值时，确定上述从设备在低频信号的辐射范围内，这时，从设备会向主设备发送应答信号，主设备根据接收到的应答信号，即可确定携带从设备的车辆与上述主设备之间的距离小于上述低频信号的辐射半径，从而可以实现对携带从设备的车辆进行精准定位。
步骤106，与上述从设备进行通信，获取携带上述从设备的车辆的身份信息。
本实施例中，车辆的身份信息可以包括：车牌号码、发动机号和车架号之一或组合，当然上述车辆的身份信息还可以包括其他可唯一标识车辆的信息，本实施例对上述车辆的身份信息所包括的具体信息不作限定。
具体地，与上述从设备进行通信，获取携带上述从设备的车辆的身份信息可以为：与上述从设备进行通信，接收上述从设备发送的携带上述从设备的车辆的身份信息；或者，与上述从设备进行通信，接收上述从设备发送的上述从设备的标识，根据上述从设备的标识获取携带上述从设备的车辆的身份信息。
也就是说，一种实现方式中，可以将上述车辆的身份信息预先存储在从设备中，在主设备与从设备进行通信的过程中，从设备可以直接将携带上述从设备的车辆的身份信息发送给主设备，主设备接收上述从设备发送的车辆的身份信息。
另一种实现方式中，在初次使用从设备时，用户可以将从设备的标识、携带上述从设备的车辆的身份信息提交给服务器，在主设备与从设备进行通信的过程中，从设备只需将自身的标识发送给主设备，主设备接收上述从设备的标识，进而根据上述从设备的标识从服务器中获取携带上述从设备的车辆的身份信息。
进一步地，在获取车辆的身份信息之后，主设备可以与上述服务器进行通信，将上述车辆的身份信息发送给服务器，进而服务器可以获取与上述车辆的身份信息关联的用户账号，然后执行从上述用户账号中扣除车费，和/或向上述用户账号推送消息等操作。
上述车辆身份的识别方法中，主设备发送低频信号之后，接收从设备发送的针对上述低频信号的应答信号，与上述从设备进行通信，获取携带上述从设备的车辆的身份信息，从而可以实现对车辆身份进行识别，由于上述应答信号是从设备接收到上述低频信号，并且检测到上述低频信号的信号强度大于或等于预定阈值之后发送的，并且随距离增长，低频信号的信号强度迅速衰减，因此主设备根据接收到的应答信号，即可确定携带从设备的车辆的位置，从而可以实现对携带从设备的车辆进行精准定位，避免了跟车干扰和邻道干扰的问题，提高了车辆身份识别的准确率。
图3为本说明书车辆身份的识别方法另一个实施例的流程图，如图3所示，步骤106之前，还可以包括：
步骤302，根据上述应答信号确定上述从设备在上述低频信号的辐射范围内，并确定携带上述从设备的车辆为当前待识别的车辆。
本实施例中，由于上述低频信号的辐射范围可以包括上述低频信号的辐射角度和辐射半径，因此上述从设备在上述低频信号的辐射范围内可以为上述从设备与上述主设备之间的距离小于或等于上述低频信号的辐射半径。
具体地，当从设备检测到低频信号的信号强度大于或等于预定阈值时，确定上述从设备在低频信号的辐射范围内，即上述从设备与上述主设备之间的距离小于或等于上述低频信号的辐射半径，这时，从设备会向主设备发送应答信号，那么主设备根据接收到的应答信号，即可确定上述从设备在上述低频信号的辐射范围内，进而可以确定携带上述从设备的车辆的位置在低频信号的辐射范围内。可以理解的是，由于低频信号的辐射范围就是根据主设备与需要检测的车道的相对位置，以及车道的宽度和/或车辆的长度等设定的，因此主设备可以确定在低频信号的辐射范围内的车辆为当前待识别的车辆，从而可以实现对携带从设备的车辆进行精准定位，避免了跟车干扰和邻道干扰的问题，提高了车辆身份识别的准确率。
图4为本说明书车辆身份的识别方法再一个实施例的流程图，如图4所示，上述车辆身份的识别方法可以包括：步骤402，从设备接收主设备发送的低频信号。
其中，主设备是指主动发送低频信号的设备，与主设备对应的是从设备，从设备一般处于睡眠状态。本实施例中，主设备可以安装在路边某个固定位置，如图2所示，主 设备发送的低频信号的辐射范围是预先设定的，从设备可以安装在车辆上，从设备进入低频信号的辐射范围之后，可以接收到上述主设备发送的低频信号。
步骤404，检测上述低频信号的信号强度。
步骤406，如果上述低频信号的信号强度大于或等于预定阈值，则向上述主设备发送应答信号。
其中，上述预定阈值可以在具体实现时，根据实现需求和/或系统性能等自行设定，本实施例对上述预定阈值的大小不作限定。
具体地，从设备接收到低频信号之后，对上述低频信号的信号强度进行检测，如果上述低频信号的信号强度大于或等于预定阈值，则从设备确定自身在低频信号的辐射范围内，这时，从设备会向主设备发送应答信号，那么主设备根据接收到的应答信号，即可确定携带从设备的车辆的位置，从而可以实现对携带从设备的车辆进行精准定位。
步骤408，与上述主设备进行通信，以使上述主设备获取携带上述从设备的车辆的身份信息。
本实施例中，车辆的身份信息可以包括：车牌号码、发动机号和车架号之一或组合，当然上述车辆的身份信息还可以包括其他可唯一标识车辆的信息，本实施例对上述车辆的身份信息所包括的具体信息不作限定。
具体地，与上述主设备进行通信，以使上述主设备获取携带上述从设备的车辆的身份信息可以为：与上述主设备进行通信，将携带上述从设备的车辆的身份信息发送给上述主设备；或者，与上述主设备进行通信，将上述从设备的标识发送给上述主设备，以使上述主设备根据上述从设备的标识获取携带上述从设备的车辆的身份信息。
上述车辆身份的识别方法中，从设备接收主设备发送的低频信号之后，检测上述低频信号的信号强度，如果上述低频信号的信号强度大于或等于预定阈值，则向上述主设备发送应答信号，并与上述主设备进行通信，以使上述主设备获取携带上述从设备的车辆的身份信息，从而可以实现主设备对携带从设备的车辆进行精准定位，避免了跟车干扰和邻道干扰的问题，提高了车辆身份识别的准确率。
图5为本说明书车辆身份的识别方法再一个实施例的流程图，如图5所示，上述车辆身份的识别方法可以包括：步骤502，主设备发送低频信号，上述低频信号的辐射范围是预先设定的。
具体地，上述低频信号的辐射范围可以包括上述低频信号的辐射角度和辐射半径，本实施例中，主设备可以安装在车辆上，从设备可以安装在路边某个固定位置，如图6所示，因此在具体实现时，可以根据从设备的安装位置，设定低频信号的辐射角度和辐射半径，使得安装有上述主设备的车辆，行驶在安装有从设备的道路上时，上述主设备发送的低频信号的辐射范围可以覆盖上述从设备。其中，图6为本说明书另一个实施例提供的主设备和从设备的安装位置的示意图。
步骤504，接收从设备发送的针对上述低频信号的应答信号，上述应答信号是从设备接收到上述低频信号，并且检测到上述低频信号的信号强度大于或等于预定阈值之后 发送的。
具体地，上述预定阈值可以在具体实现时，根据实现需求和/或系统性能等自行设定，本实施例对上述预定阈值的大小不作限定。
由于随距离增长，低频信号(主要是磁场信号)的信号强度迅速衰减，可以做到在3m外信号强度趋近于0，因此在预先设定低频信号的辐射范围之后，只有当从设备进入低频信号的辐射范围，上述从设备才会由睡眠状态被唤醒。当从设备检测到上述低频信号的信号强度大于或等于预定阈值时，确定上述从设备在低频信号的辐射范围内，这时，从设备会向主设备发送应答信号，主设备根据接收到的应答信号，即可确定携带主设备的车辆与从设备之间的距离小于或等于上述低频信号的辐射半径。
步骤506，与上述从设备进行通信，以使上述从设备获取携带上述主设备的车辆的身份信息。
具体地，与上述从设备进行通信，以使上述从设备获取携带上述主设备的车辆的身份信息可以为：与上述从设备进行通信，将携带上述主设备的车辆的身份信息发送给上述从设备；或者，与上述从设备进行通信，将上述主设备的标识发送给上述从设备，以使上述从设备根据上述主设备的标识获取携带上述主设备的车辆的身份信息。
也就是说，一种实现方式中，可以将上述车辆的身份信息预先存储在主设备中，在主设备与从设备进行通信的过程中，主设备可以直接将携带上述主设备的车辆的身份信息发送给从设备，从设备接收上述主设备发送的车辆的身份信息。
另一种实现方式中，在初次使用主设备时，用户可以将主设备的标识、携带上述主设备的车辆的身份信息提交给服务器，在主设备与从设备进行通信的过程中，主设备只需将自身的标识发送给从设备，从设备接收上述主设备的标识，进而根据上述主设备的标识从服务器中获取携带上述主设备的车辆的身份信息。

上述车辆身份的识别方法中，主设备发送低频信号之后，接收从设备发送的针对上述低频信号的应答信号，与上述从设备进行通信，以使上述从设备获取携带上述主设备的车辆的身份信息，从而可以实现对车辆身份进行识别，由于上述应答信号是从设备接收到上述低频信号，并且检测到上述低频信号的信号强度大于或等于预定阈值之后发送的，并且随距离增长，低频信号的信号强度迅速衰减，因此主设备根据接收到的应答信号，即可确定从设备与携带主设备的车辆之间的距离，从而可以实现对携带主设备的车辆进行精准定位，避免了跟车干扰和邻道干扰的问题，提高了车辆身份识别的准确率。
