Description

路况信息收集方法、装置及用户终端 技术领域
本发明涉及通信领域，具体而言，涉及一种路况信息收集方法、装置及用户终端。
背景技术
由于公路养护不及时，公路路面上进场会有一些坑洼，特别是天黑或者雨后视线不好的时候，无法提前躲避，给过往的车辆造成不便。特别是剧烈的颠簸会给车辆中的特殊乘坐人群(例如孕妇或者其他病人)造成危害。另外高速通过这种坑洼对车辆本身的损伤也会很大，可能造成爆胎或者其他的行车危险。此外，公路、尤其高速公路上突发交通事故或者出现道路拥塞，如果没有提前预警，可能引发更严重的交通事故。
相关技术中路况告警主要采用交通广播的方式，在广播范围内的车辆都能收到交通广播。这种方式针对性较弱，即：有的车辆在广播范围内，但实际上，该车辆由于行驶方向或者行驶目的不同而已经绕开了事故路段，则无需了解该路段的路况告警。此外，交通广播告警若要实现实时告警，则需要不间断广播相同信息，造成了对广播范围内逗留的车辆的广播干扰。
此外，相关技术中还采用在车载导航系统中增加路况信息标注和告警的方式，实现在车载导航的过程中的路况信息收集和查询告警。研究过程中发现，由于车载导航系统搭配在固定的车辆上，对于经常更换车辆驾驶的用户(例如租车自驾用户)，常常会因为更换了车辆而导致原先车辆上的路况信息无法移植到新车辆上的问题。另外，现有的车载导航系统从成本考虑，往往没有内置无线通讯模块，这些车载导航系统需要软件更新或者数据升级时，采用离线更新包方式更新。因此，若要通过车载导航系统实现当前车辆与其他车辆或者服务器的无线连接以共享路况数据，则涉及到现有的车载导航系统的硬件更新，例如，在车载导航系统中新增无线通讯模块，增加了应用成本。
针对相关技术中在车载导航系统中存储路况信息导致的路况信息的可移植性差的问题，目前尚未提出有效的解决方案。

具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
在本实施例中提供了一种路况信息收集方法，图1是根据本发明实施例的路况信息收集方法的流程图，如图1所示，该流程包括如下步骤：
步骤S102，用户终端接收车辆采集到的路况信息；
步骤S104，用户终端检测采集路况信息时车辆的位置、在位置上车辆的行驶方向；
步骤S106，用户终端将路况信息、位置和行驶方向保存或更新至路况信息库。
通过上述步骤，将路况信息保存在用户终端中，使得路况信息的存储与车辆分离，从而提高了路况信息的可移植性，解决了在车载导航系统中存储路况信息导致的路况信息的可移植性差的问题。
道路一般有两个或者多个车道，这些车道中有的车道规定的行驶方向相反。在这种情况下，以上行车道和下行车道为例，在上行车道出现交通拥堵、路面颠簸等情况下，下行车道由可能是处于正常状态。这种情况在高速公路上尤为突出。
车辆的位置一般采用卫星定位系统、基站辅助定位装置、无线局域网辅助定位装置等位置定位装置来检测。相关技术中的卫星定位系统或者基站辅助定位等位置检测技术，其确定的位置精度一般在数米的范围内，即商用的卫星定位系统无法定位车辆所处的车道信息，因此，即使已知某一路段存在交通异常状况，由于无法判断车辆所在的车道是上行车道还是下行车道，也不知道交通异常状况出现在上行车道还是下行车道，则只能对所有路过该路段的上行车道和下行车道上的所有车辆进行告警，同样也会导致告警缺乏针对性的问题。
在本发明实施例中，在采集路面状况信息的同时，同时也采集车辆的行驶方向，以辅助判别交通异常状况。通过对车辆的行驶方向的判断，结合位置信息，则可以判断该车辆在哪一条道路的哪一个方向的车道上行驶，从而可以提高针对路况信息进行的路况告警的精确度。
用户终端与车辆之间可以通过各种有线或者无线接口实现数据互通，例如，采用蓝牙收发器、红外数据收发器或者近场通讯等各种无线方式，或者采用数据线连通移动终端和车辆的方式，实现车辆和移动终端之间数据互通。
本发明实施例的用户终端包括：便携式终端；较优的，该用户终端内置无线通讯模块，通过无线通讯模块，可以实现用户终端与其他用户终端的信息共享，例如，与预定区域内的多个用户终端通过自组网形式相互共享数据；或者通过无线通讯模块，实现用户终端与服务器的数据共享。无线通讯模块可以支持所有的无线通讯技术，例如：无线局域网(WLAN)、无线保真(WiFi)、全球移动通讯技术(GSM)、第三代移动通信技术、第四代移动通信技 术及后续演进的移动通讯技术。
通过上述无线通讯模块，用户终端可以从其他用户终端或者服务器接收路况更新信息；并根据路况更新信息，更新路况信息库。
相应地，用户终端也可以发送路况更新信息至其他用户终端或者服务器，其中，路况更新信息包括：位置、行驶方向以及路况信息。
可选地，路况信息包括但不限于以下至少之一：交通拥堵信息、路面颠簸信息、交通事故信息。
可选地，在路况信息包括路面颠簸信息(或者其他可以由车辆采集的路况信息)的情况下，在检测车辆的该位置对应的路面颠簸信息时，可以从车辆接收这些路面颠簸信息，其中，路面颠簸信息是由车辆上的感应器检测的得到的。上述的路面颠簸信息包括但不限于：车辆的震动幅度、和/或，车辆倾斜的角度。
采用车辆上的感应器检测路面颠簸信息，可以有效避免采用用户终端直接检测路面颠簸信息时由于用户对用户终端的移动操作导致的震动，从而误报路面颠簸信息的问题。
可选地，对于路况信息的保存和更新，为了减少数据量，可以忽略正常的路况信息，而仅保存指示路况异常的路况信息。例如，用户终端判断路况信息是否指示为路况异常；在判断结果为是的情况下，用户终端检测采集路况信息时车辆的位置、在位置上车辆的行驶方向。其中，对于可以量化的路况信息，例如，路面颠簸信息，可以在路面颠簸程度达到预定阈值的情况下，自动判断该路面路况存在异常。对于难以量化或者不可量化的路况信息，例如，交通事故信息，则可以通过用户的主动触发上报的方式，实现交通事故信息的收集。
可选地，在用户终端将路况信息、位置和行驶方向保存或更新至路况信息库之后，本发明实施例提供了一种保存的路况信息的使用场景。例如，用户终端检测车辆的当前位置和当前行驶方向；用户终端根据当前位置和当前行驶方向，确定待查询路况信息的位置范围；用户终端在路况信息库中查询处于位置范围内的位置的路况信息；在查询到路况信息指示路况异常的情况下，用户终端进行告警。当然，对于路况信息的使用并不仅限于上述的场景。例如，保存的路况信息上传至服务器之后，还可以对路况信息进行大数据分析，以实现其他的应用。
可选地，在用户终端根据当前位置和当前行驶方向，确定待查询路况信息的位置范围时，用户终端可以确定从当前位置开始、沿当前行驶方向延伸预定距离的道路为位置范围，从而实现了路况的提前预警。
可选地，上述的预定距离是根据以下之一的方式确定的：预设的固定值，例如，可以固定设置为50米；根据车辆的行驶速度确定的，其中，行驶速度越大，预设距离越大，例如，在行驶速度小于60公里每小时的情况下，可以设置预定距离为80米，在形式速度大于100公里每小时的情况下，可以设置预定距离为150米。根据车辆的行驶速度确定进行告警检测的位置范围，可以保障驾驶人员足够的反应时间。
在不冲突的情况下，本发明实施例中的路况信息库可以是保存在用户终端中的，也可以是保存在服务器中的。当路况信息库保存在服务器中的情况下，可以通过用户终端和服务器之间的信息交互，实现路况信息库的更新以及路况信息在路况信息库中的查询操作。
可选地，车辆的行驶方向可以通过地磁传感器或者位置定位装置检测。其中，位置定位装置包括：卫星定位装置、基站辅助定位装置、无线局域网辅助定位装置等。在采用位置定位装置时，可以通过比较多个连续的位置的时间顺序，确定车辆的行驶方向。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本发明各个实施例的方法。
在本实施例中还提供了一种路况信息收集装置，应用于用户终端。该装置用于实现上述实施例及优选实施方式，已经进行过说明的不再赘述。如以下所使用的，术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。

第一接收模块22，设置为接收车辆采集到的路况信息；第一检测模块24，设置为检测采集路况信息时车辆的位置、在位置上车辆的行驶方向；存储模块26，耦合至第一接收模块22和第一检测模块24，设置为将路况信息、位置和行驶方向保存或更新至路况信息库。

本发明的实施例还提供了一种存储介质。在本实施例中，上述存储介质可以被设置为存储用于执行以下步骤的程序代码：
步骤S102，用户终端接收车辆采集到的路况信息；

可选地，本实施例中的具体示例可以参考上述实施例及可选实施方式中所描述的示例，本实施例在此不再赘述。
为了使本发明实施例的描述更加清楚，下面结合可选实施例进行描述和说明。
本发明可选实施例提供了一种路面危险预警的方法，在本发明可选实施例中，利用车辆上分布的传感器来收集车辆本身的情况以及行驶情况，例如氧传感器，转速传感器，温度传 感器等，从而实现路况信息的采集。
在本发明可选实施例中，以移动终端协同车辆执行路面坑洼告警(即基于路面颠簸信息的告警)为例进行描述和说明。使用移动终端与车辆连接，当车辆在行驶中遇到坑洼，造成车辆剧烈震动时，移动终端通过分布在车身的振幅传感器收集到震动信息(振幅信息)，通过震动程度可以判断出造成震动的坑洼的大小，并通过移动终端的卫星定位模块(例如全球定位系统GPS)获取发生震动时的车辆位置信息，移动终端通过保存相关信息。当下一次车辆行驶到同位置时，预先提醒驾驶员地面可能会有坑洼，注意避让。
为了实现上述方法，本发明可选实施例提供了一种路面危险预警装置，该装置包括：连接模块，信息收集模块，定位模块，处理模块和提醒模块。
图7是根据本发明可选实施例的路面危险预警装置的结构框图，图7是图2～图6的变形形式。如图7所示，该装置包括：连接模块701、信息收集模块702、定位模块703、处理模块704和提醒模块705；其中：
连接模块701设置为移动终端同汽车建立连接；信息收集模块702设置为通过汽车的振幅传感器收集行驶过程中的振幅信息，发送给处理模块704；定位模块703设置为获取车辆的位置信息和行驶方向信息，发送给处理模块704；处理模块704设置为收集通过数据采集模块702获取的汽车振幅信息，判断是否存在危险性坑洼，如果存在则通过定位模块703获取当前位置信息并保存。
等待下次即将接近已保存位置信息的地点时，启动通知模块705；通知模块705设置为通知用户前方可能存在路面危险，建议用户提前做出避让。
图8是根据本发明可选实施例的信息采集方法的流程图，如图8所示，该流程包括如下步骤：
步骤S801：将移动终端与汽车建立连接，连接方式可以通过有线方式，也可以通过无线方式。
步骤S802：移动终端通过分布在车身上传感器收集汽车在行驶中的震动信息；传感器包括但不限于：加速度传感器，用来确定振幅大小；角速度传感器，用来确定车辆倾斜情况；
步骤S803：将收集到的信息发送给移动终端的处理模块。
步骤S804：处理模块对信息作出解析和判断，预设一个振幅阀值。当传感器传来汽车振幅信息小于这个预设值的时候，认为是无效信息，重新解析新的振幅信息；如果该振幅信息大于预设值，则认为此处路面存在坑洼。
步骤S805：通过定位模块获取存在坑洼处的位置信息；
步骤S806：获取当前车辆行驶方向信息，优先的，可以使用卫星定位(例如GPS)方式，也可以使用地磁传感器的方式；
步骤S807：保存坑洼处的相关信息以及当前车辆的行驶方向信息。
图9是根据本发明可选实施例的路面危险预警方法的流程图，如图9所示，该流程包括如下步骤：
步骤S901：处理模块通过定位模块获取当前车辆的位置信息和行驶方向信息；
步骤S902：预先设定预警距离，对比已保存的路面坑洼的位置信息和运行方向信息，判断出当前方向上预警距离内是否存在路面坑洼。
步骤S903：如果存在路面坑洼，则通知提醒模块.
步骤S904：提醒模块提醒用户，前方可能存在路面坑洼，建议用户提前减速做出避让。
本发明可选实施例还提供了四种应用场景下本发明的应用实例，下面分别以四种应用场景为例进行描述和说明。
场景一
用户把手机，通过蓝牙与车载系统连接，打开路面预警功能，开始驾驶。
当用户驾驶汽车行驶时通过一个坑洼，车辆剧烈颠簸，手机收集到车身传感器上传的信息，判断存在坑洼，同时通过GPS模块获取当前的位置信息，通过GPS定位或者地磁传感器获取当前行驶方向，保存上述信息。
场景二
用户收集到一些预警点信息，使用分享功能，把自己收集到的路面信息分享给其他用户。可以通过网络侧分享，也可以通过点对点连接后直接分享。
接收到其他用户分享的信息后，选择保存，可以更新接收手机的路面预警点信息。
场景三
用户手机中预先已经保存了之前行驶中记录的预警点，这些预警点可以是用户自己收集的，也可以是其他用户分享的。
当用户行驶中接近某个预警点位置，并且当前行驶方向和之前保存的行驶方向也相同时，终端会根据预设的预警距离，提前做出判断，当到达预警距离时，会通知给用户，用户做出预先操作，从而降低的行驶的风险。
场景四
当用户打开预警功能，接收到预警信息，前方路段可能存在路面问题。
用户降低车速，行驶过预警点，未发现路面问题。
用户确认该路面问题已经被修改，可以从手机中删除该报警点信息，后续再通过该路段 时，不会再有告警信息提示。
显然，本领域的技术人员应该明白，上述的本发明的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本发明不限制于任何特定的硬件和软件结合。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
