Description

一种实时路况监控方法和实时路况监控设备 技术领域
本发明涉及交通信息技术领域，具体涉及一种实时路况监控方法和实时路况监控设备。
 背景技术
随着人们物质生活水平的提高，私家车拥有率呈逐年上升趋势，越多越多的人为方便出行而购买了汽车。车辆的急剧增多，与之对应的是越来越挤的道路和堵塞在道路上越来越密集的汽车。由于各种原因，我国一年因交通拥堵造成的损失约1700亿元，并逐年上升。如果能够监控城市道路的路况，则可以在道路出现拥堵时采取相应的措施，从而避免道路出现长期拥堵的现象，在一定程度上缓解道路塞车的情况。
目前主要通过如下方式监控城市道路的路况：通过在城市的主干道上使用地图线圈、测速雷达和测速摄像头等工具采集道路的占用率、车流量和车速等路况。
然而，上述方案虽然能够实现对城市主干道的路况监控，则需要在城市的各个主干道上安置地图线圈、测速雷达和测速摄像头等工具，方案实施成本（例如工具采购成本、施工成本）较高。
 技术问题
本发明提供一种实时路况监控方法和实时路况监控设备，用于节约成本。
 技术解决方案
本发明第一方面提供一种实时路况监控方法，包括：
获取车载终端反馈的上述车载终端所在车辆的行车记录信息；
根据上述车辆的行车记录信息，确定并记录上述车辆当前的路况信息，其中，上述车辆当前的路况信息包括：上述车辆当前所处的路段、上述车辆当前的行车方向以及上述车辆当前的行车速度；
若上述车辆当前的行车速度低于预设阈值，则判断是否记录有N个满足条件的其它车辆的路况信息，其中，上述N大于或等于1；
若记录有N个满足条件的其它车辆的路况信息，则判定上述车辆当前所处的路段处于拥堵状态；
其中，上述满足条件的其它车辆的路况信息具体为：路况信息的记录时间点与获取上述车辆的行车记录信息的时间点的间隔在预设门限值内，且路况信息中记录的车辆所处路段和行车方向与上述车载终端所在车辆相同，且路况信息中记录的行车速度低于上述预设阈值。
本发明另一方面提供一种实时路况监控设备，包括：
获取单元，用于获取车载终端反馈的上述车载终端所在车辆的行车记录信息；
确定单元，用于根据上述获取单元获取的上述车辆的行车记录信息，确定上述车辆当前的路况信息，其中，上述车辆当前的路况信息包括：上述车辆当前所处的路段、上述车辆当前的行车方向以及上述车辆当前的行车速度；
记录单元，用于记录上述确定单元确定的上述车载终端所在车辆当前的路况信息；
判断单元，用于当上述车辆当前的行车速度低于预设阈值时，判断上述记录单元是否记录了N个满足条件的其它车辆的路况信息，其中，上述N大于或等于1；
判定单元，用于当上述判断单元判断出上述记录单元记录了N个满足条件的其它车辆的路况信息时，判定上述车辆当前所处的路段处于拥堵状态；
其中，上述满足条件的其它车辆的路况信息具体为：路况信息的记录时间点与获取上述车辆的行车记录信息的时间点的间隔在预设门限值内，且路况信息中记录的车辆所处路段和行车方向与上述车载终端所在车辆相同，且路况信息中记录的行车速度低于上述预设阈值。
 有益效果
从本发明上述技术方案可知，本发明通过车载终端反馈车辆的行车记录信息，并根据行车记录信息确定和记录车辆的路况信息，当某一时间段内处于相同路段和相同行车方向的多个车辆的行车速度低于预设阈值时，判定该路段处于拥挤状态。本发明通过车载终端反馈的行车记录信息便可实现对路况的拥挤状态的判定，相对于现有的通过地图线圈、测速雷达和测速摄像头等工具对路况的检测方案，节省了工具采购成本、施工成本的投入，从而有效节约了成本。
 附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。

图2为本发明提供的一种实时路况监控***架构示意图；
图3为本发明提供的一种实时路况监控方法一个应用场景时序图；
图4为本发明提供的一种实时路况监控方法一个实施例结构示意图。
 本发明的实施方式
为使得本发明的发明目的、特征、优点能够更加的明显和易懂，下面将结合本发明实施例中的附图，对本发明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本发明一部分实施例，而非全部实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
下面对本发明实施例中的一种实时路况监控方法进行描述，请参阅图1，本发明实施例中的实时路况监控方法，包括：
101、获取车载终端反馈的该车载终端所在车辆的行车记录信息；
本发明实施例中，车载终端周期性向服务器反馈该车载终端所在车辆的行车记录信息，或者，车载终端在检测到该车载终端所在车辆的行车速度小于预设阈值时，向服务器反馈该车载终端所在车辆的行车记录信息，此处不作限定。
可选的，本发明实施例中的车载终端为车辆诊断设备，车辆诊断设备可以实时采集汽车全***各种运行数据包括故障信息、数据流、位置信息、车辆状态等，从而实现“实时远程诊断”、“车辆专业体检”、“车辆报警提醒”、“车主生活社区”以及“地图定位服务”等各种汽车应用。本发明实施例中，将车辆诊断设备的接头***车辆的车载诊断***（OBD，On-Board Diagnostic）接口，以实现车辆诊断设备与车辆的OBD的连接，当车辆诊断设备与车辆的OBD连接之后，车辆诊断设备会实时捕获由车辆的OBD接口送出的信号（信号包括车辆的行车记录信息），车辆诊断设备捕获到信号后进行数据解析处理后反馈给上述服务器。可选地，通过无线网络获取车辆诊断设备反馈的所述车辆诊断设备所在车辆的行车记录信息。具体的，本发明实施例中的车辆诊断设备为golo3设备（即第3代golo设备），由于golo3设备支持无线保真（Wi-Fi，Wireless-Fidelity）网络，因此，golo3设备可以通过Wi-Fi网络向服务器反馈golo3设备所在车辆的行车记录信息。
102、根据上述车辆的行车记录信息，确定并记录上述车辆当前的路况信息；
其中，上述车辆当前的路况信息包括：上述车辆当前所处的路段、上述车辆当前的行车方向以及上述车辆当前的行车速度。
本发明实施例中，服务器在接收到车载终端反馈的车辆的行车记录之后，根据该行车记录确定该车辆当前的路况信息，并将该车辆当前的路况信息记录在数据库中，可选的，若数据库中已经存储该车辆之前的路况信息，则用该车辆当前的路况信息覆盖数据库存储的该车辆之前的路况信息，以更新数据库。
103、若上述车辆当前的行车速度低于预设阈值，则判断是否记录有N个满足条件的其它车辆的路况信息；
其中，上述N大于或等于1，N的取值根据实际情况进行设定。上述满足条件的其它车辆的路况信息具体为：路况信息的记录时间点与获取上述车辆的行车记录信息的时间点的间隔在预设门限值内，且路况信息中记录的车辆所处路段和行车方向与上述车载终端所在车辆相同，且路况信息中记录的行车速度低于上述预设阈值。
举例说明，假设获取车辆A的行车记录信息的时间点在3点10分，预设门限值为5分钟，则当车辆A当前的行车速度低于预设阈值时，服务器在数据库中查找在3点05分至3点15分这个时间段内记录的车辆的路况信息，若在3点05分至3点15分这个时间段内，存在N个车辆的路况信息的记录，且这N个车辆所处路段、行车方向均与车辆A所处路段、行车方向相同，那么服务器判定记录有N个满足条件的其它车辆的路况信息。
可选的，在步骤101获取车载终端反馈的该车载终端所在车辆（假设为车辆A）的行车记录信息时，记录获取车辆A的行车记录信息的时间点，并根据预设门限值往后推一个时间段，作为判定车辆A当前所在路段的路况的一个时间段，当车辆A当前的行车速度低于预设阈值，判断是否记录有N个满足条件的其它车辆的路况信息。举例说明，假设获取车辆A的行车记录信息的时间点在3点10分，预设门限值为5分钟，则将3点10分往后推移5分钟，即，将3点05分至3点10分作为判定车辆A当前所在路段的路况的一个时间段，服务器在数据库中查找在3点05分至3点10分这个时间段内记录的车辆的路况信息，若在3点05分至3点10分这个时间段内，存在N个车辆的路况信息的记录，且这N个车辆所处路段、行车方向均与车辆A所处路段、行车方向相同，那么服务器判定记录有N个满足条件的其它车辆的路况信息。
可选的，在不同的路段上，上述阈值的取值可能不同，即，上述阈值可以根据具体路段的情况设置不同的取值，则步骤103具体为：服务器判断上述车辆当前的行车速度是否低于与该车辆当前所在路段所对应的预设阈值，如果是，则判断是否记录有N个满足条件的其它车辆的路况信息，如果否，则返回步骤101，或者，立即或在等待预置时长或在预设事件发生时结束本次流程。
当服务器判断出记录有N个满足条件的其它车辆的路况信息时，执行步骤104，当服务器判断出未记录有N个满足条件的其它车辆的路况信息时，返回步骤101，或者，立即或在等待预置时长或在预设事件发生时结束本次流程。
104、判定上述车辆当前所处的路段处于拥堵状态；
进一步，服务器在判定上述车辆当前所处的路段处于拥堵状态后，还可以输出步骤104的判定结果，以便根据判定结果执行相应的解决该路段拥堵的措施。
可选的，服务器在判定上述车辆当前所处的路段处于拥堵状态时或之后，向服务器监控范围内的所有移动终端（例如手机、平板电脑、车载终端或者其它具有无线数据接收功能的移动终端）发送提醒消息，该提醒消息指示该路段处于拥堵状态。
可选的，服务器在判定上述车辆当前所处的路段处于拥堵状态时或之后，向位于该路段的预设范围内（例如该路段附近1~5公里内）的移动终端发送提醒消息，该提醒消息指示该路段处于拥堵状态。
由上可见，本发明通过车载终端反馈车辆的行车记录信息，并根据行车记录信息确定和记录车辆的路况信息，当某一时间段内处于相同路段和相同行车方向的多个车辆的行车速度低于预设阈值时，判定该路段处于拥挤状态。本发明通过车载终端反馈的行车记录信息便可实现对路况的拥挤状态的判定，相对于现有的通过地图线圈、测速雷达和测速摄像头等工具对路况的检测方案，节省了工具采购成本、施工成本的投入，从而有效节约了成本。进一步，在判定路段出现拥堵时，向覆盖范围内的移动终端告知该路段拥堵，能够使得部分车主避开该路段，一方面能够节省车主的时间和车辆的油耗，另一方面，也能够有效缓解该路段的拥堵情况。
下面以一具体应用场景例对本发明实施例中的实时路况监控方法进行描述，如图2所示为本发明实施例中的实时路况监控***架构示意图，由图2可见，golo接头、服务器、移动终端通过无线网络互联。

其中，上述车辆当前的路况信息包括：上述车辆当前所处的路段、上述车辆当前的行车方向以及上述车辆当前的行车速度。
304、golo设备将上述车辆当前的路况信息存储在数据库中。
305、若上述车辆当前的行车速度低于预设阈值，则在数据库中查询数据；
当上述车辆当前的行车速度低于预设阈值时，服务器在数据库中查询满足条件的其它车辆的路况信息。
其中，上述满足条件的其它车辆的路况信息具体为：路况信息的记录时间点与获取上述车辆的行车记录信息的时间点的间隔在预设门限值内，且路况信息中记录的车辆所处路段和行车方向与上述车载终端所在车辆相同，且路况信息中记录的行车速度低于上述预设阈值。
306、数据库返回数据查询结果。
307、服务器根据查询结果判断上述车辆当前所处的路段是否处于拥堵状态；
若数据库返回的数据查询结果显示满足条件的其它车辆的路况信息的数量达到预设数量，则服务器判定上述车辆当前所处的路段处于拥堵状态，若数据库返回的数据查询结果显示满足条件的其它车辆的路况信息的数量未达到预设数量，则服务器判定上述车辆当前所处的路段处于拥堵状态。
308、当服务器判定上述车辆当前所处的路段处于拥堵状态时，向移动终端发送提醒消息；
可选的，服务器在判定上述车辆当前所处的路段处于拥堵状态时，向服务器监控范围内的所有移动终端（例如手机、平板电脑、车载终端或者其它具有无线数据接收功能的移动终端）发送提醒消息。
