Description
本发明涉及物联网技术领域，尤其涉及一种临时路边停车引起的信息公告方法及系统。
当前，随着群众生活水平的不断提升，我国的汽车刚性需求保持旺盛，汽车保有量保持迅猛增长趋势，2016年新注册登记的汽车达2752万辆，保有量净增2212万辆，均为历史最高水平。全国有49个城市的汽车保有量超过100万辆，18个城市的汽车保有量超200万辆，6个城市的汽车保有量超300万辆。其中，汽车保有量超过200万辆的18个城市依次是北京、成都、重庆、上海、深圳、苏州、天津、郑州、西安、杭州、武汉、广州、石家庄、东莞、南京、青岛、宁波、佛山。在汽车保有量保持迅猛增长的过程中，汽车交通事故也在不断上升。在实践中发现，当行驶道路(如高速公路)上有车辆临时停车时，其余车辆的驾驶员通常无法及时了解该行驶道路上有车辆临时停车，无法提前减缓车速，从而容易发生交通事故。

车载通讯终端301，用于扫描周围环境中是否预先设置有物联网接入点，如果预先设置有物联网接入点，检测物联网接入点是否被配置有开放接入时段，如果物联网接入点被配置有开放接入时段，识别车载通讯终端301的当前系统时间是否位于物联网接入点被配置的开放接入时段内；如果车载通讯终端301的当前系统时间位于物联网接入点被配置的开放接入时段内，检测物联网接入点的当前接入的终端数量是否超过物联网接入点指定的最大终端接入数量；如果物联网接入点的当前接入的终端数量未超过物联网接入点指定的最大终端接入数量，建立与物联网接入点之间的无线连接，并且将车载通讯终端301所在车辆在某一行驶道路上的临时停车位置以及车辆的车辆标识上报给物联网接入点，由物联网接入点将车载通讯终端301所在车辆在某一行驶道路上的临时停车位置以及车辆的车辆标识进行加密后发送给数据汇聚分析平台302。
作为一种可选的实施方式，在图3所描述的信息公告系统：
数据汇聚分析平台302，还用于在计算上述临时停车位置与第二车辆集合中每一目标车辆的即时位置之间的即时距离，并向目标车辆的驾驶员发送公告信息之后，判断数据汇聚分析平台302的当前工作负荷是否超过数据汇聚分析平台302指定的工作负荷，如果未超过，通过天气信息查询端口向天气信息查询端口对应的天气服务中心发起包括临时停车位置的天气信息查询请求；以及，接收天气服务中心通过天气信息查询端口返回的临时停车位置对应的预设时长(如15分钟)的天气信息；以及，将临时停车位置对应的预设时长的天气信息下发给目标车辆的驾驶员，从而使得其他车辆的驾驶员提
前预知临时停车位置对应的预设时长(如1日)的天气信息(如暴风雨)，并做好相应的准备(如开启雾灯)，以免因为天气原因与临时停车位置停放的车载通讯终端301所在车辆发送碰撞的交通事故。
可见，实施图3所描述的系统，可以使车辆驾驶员及时了解行驶道路上某一距离处有车辆临时停车，从而可以提前减缓车速，以防来不及刹车而发生交通事故。
可见，实施图3所描述的系统，可以精确的识别出驾驶员的情绪是否稳定以及识别出驾驶员的眼睛是否疲劳，从而可以避免因驾驶员的情绪不稳定或眼睛疲劳而容易发生交通事故。
可见，实施图3所描述的系统，可以避免车载通讯终端直接与数据汇聚分析平台通信带来的较大功耗。
可见，实施图3所描述的系统，可以使得其他车辆的驾驶员提前预知临时停车位置对应的预设时长(如1日)的天气信息(如暴风雨)，从而可以做好相应的准备(如开启雾灯)，以免因为天气原因与临时停车位置停放的车载通讯终端所在车辆发送碰撞的交通事故。
