无线通信终端401，用于采集其所在道路的某一位置的水位数据，并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，识别无线通信终端401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；如果无线通信终端401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，并且将该某一位置和水位数据上报给物联网接入点，由物联网接入点将该某一位置和水位数据进行加密后发送给物联网告警平台402。
作为一种可选的实施方式，在图4所描述的智慧告警系统中：
物联网告警平台402，还用于在向目标车辆上的无线车载终端下发水位超标告警信息之后，判断物联网告警平台402的当前工作负荷是否超过物联网告警平台402指定的最大工作负荷，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该某一位置的天气信息查询请求；接收天气服务中心通过天气信息查询端口返回的该某一位置对应的预设时长的天气信息；将该某一位置对应的预设时长的天气信息下发给目标车辆上的无线车载终端。
作为一种可选的实施方式，在图4所描述的智慧告警系统中：
物联网告警平台402，还用于在将该某一位置对应的预设时长的天气信息下发给目标车辆上的无线车载终端之后，向目标车辆上的无线车载终端下发指示消息，指示消息用于指示目标车辆上的无线车载终端每隔指定时间采集一帧目标车辆上的驾驶员的人脸图像并上报给物联网告警平台402；从人 脸图像中确定出人眼定位矩形，并计算人眼定位矩形的面积，根据阈值判断驾驶员的眼睛的睁闭程度，以及根据驾驶员的眼睛的睁闭程度评价出人眼疲劳程度值，以及基于人眼疲劳程度值判断驾驶员的眼睛是否疲劳，如果疲劳，向目标车辆上的无线车载终端下发提示信息，提示信息用于提示驾驶员停车。
作为一种可选的实施方式，在图4所描述的智慧告警系统中：
物联网告警平台402，还用于检测目标车辆上的无线车载终端上报的目标车辆在该道路上的临时停车位置；以及，将包括该临时停车位置的临时停车公告信息发布给其余车辆的无线车载终端；其中，其余车辆是指接入物联网告警平台402的、在该道路上且驶向该临时停车位置的其余车辆。
可见，实施图4所描述的基于车辆的智慧告警系统，可以及时将车辆行驶方向上的某一位置水位超标告警信息通知驾驶员，防止造成水淹车辆事故。
此外，实施图4所描述的基于车辆的智慧告警系统，还可以避免无线通信终端401直接与物联网告警平台402通信带来的较大功耗。
此外，实施图4所描述的基于车辆的智慧告警系统，还可以避免车辆到达该某一位置时因为驾驶员的眼睛、天气原因和水位超标这三重因素而发生交通事故。
此外，实施图4所描述的基于车辆的智慧告警系统，还可以使在该道路上且驶向该临时停车位置的其余车辆的驾驶员及时了解该道路上某一位置处有车辆临时停车，从而可以提前减缓车速，以防发生交通事故。
