Description
本发明涉及物联网技术领域，尤其涉及一种应用于车辆的危险信息发布方法及系统。

实施例一
请参阅图1，图1是本发明实施例公开的一种应用于车辆的危险信息发布方法的流程示意图。如图1所示，该应用于车辆的危险信息发布方法可以包括以下步骤：
101、无线采集终端采集其所在城市的某一位置的水质数据，并将该某一位置和水质数据上报给物联网数据分析系统。
本发明实施例中，无线采集终端内置的无线通讯模块在生产时，可以输入上频点470MHz，下频点510MHz，这样无线通讯模块可以自动将通讯频
段定义为470MHz～510MHz，以符合中国SRRC标准的规定；或者，也可以输入上频点868MHz，下频点908MHz，这样无线通讯模块可以自动将通讯频段定义为868MHz～908MHz，以符合欧洲ETSI标准的规定；或者，可以输入上频点918MHz，下频点928MHz，这样无线通讯模块可以自动将通讯频段定义为918MHz～928MHz，以符合美国FCC标准的规定；或者，无线通讯模块的通讯频段也可以定义为符合日本ARIB标准或加拿大IC标准的规定，本发明实施例不作限定。

作为一种可选的实施方式，无线采集终端采集其所在城市的某一位置的水质数据，并将该某一位置和水质数据上报给物联网数据分析系统的方式可以为：
无线采集终端采集其所在城市的某一位置的水质数据，并扫描周围环境中是否预先设置有AP接入点，如果预先设置有AP接入点，检测AP接入点是否被配置有开放接入时段，如果AP接入点被配置有开放接入时段，识别无线采集终端的当前系统时间是否位于AP接入点被配置的开放接入时段内；
如果无线采集终端的当前系统时间位于AP接入点被配置的开放接入时段内，检测AP接入点的当前接入的终端数量是否超过AP接入点指定的最大终端接入数量；
如果AP接入点的当前接入的终端数量未超过AP接入点指定的最大终端接入数量，无线采集终端建立与AP接入点之间的无线连接，并且将该某一位置和水质数据上报给AP接入点，由AP接入点将该某一位置和水质数据进行加密后发送给物联网数据分析系统。
本发明实施例中，由AP接入点将该某一位置和水质数据进行加密后发送给物联网数据分析系统可以避免无线采集终端直接与物联网数据分析系统建立较长距离的通信连接，从而可以避免无线采集终端直接与物联网数据分
析系统通信带来的较大功耗。
102、物联网数据分析系统对水质数据进行分析，在分析出水质数据超标时，根据接入物联网数据分析系统的各个车辆的无线车载终端上报的车辆即时位置进行大数据分析，确定出与该某一位置之间的距离小于指定距离的目标车辆。

103、物联网数据分析系统向目标车辆上的无线车载终端下发水质数据超标告警信息，该水质数据告警信息包括该某一位置。
可见，实施图1所描述的应用于车辆的危险信息发布方法，可以利用无线车载终端进行及时、广泛的水质数据超标告警，减少给城市造成的灾害。
此外，实施图1所描述的应用于车辆的危险信息发布方法，可以避免无线采集终端直接与物联网数据分析系统通信带来的较大功耗。
实施例二
请参阅图2，图2是本发明实施例公开的另一种应用于车辆的危险信息发布方法的流程示意图。如图2所示，该应用于车辆的危险信息发布方法可以包括以下步骤：
201、无线采集终端采集其所在城市的某一位置的水质数据，并将该某一位置和水质数据上报给物联网数据分析系统。
作为一种可选的实施方式，无线采集终端采集其所在城市的某一位置的水质数据，并将该某一位置和水质数据上报给物联网数据分析系统的方式可以为：
无线采集终端采集其所在城市的某一位置的水质数据，并扫描周围环境中是否预先设置有AP接入点，如果预先设置有AP接入点，检测AP接入点是否被配置有开放接入时段，如果AP接入点被配置有开放接入时段，识别无线采集终端的当前系统时间是否位于AP接入点被配置的开放接入时段
内；
如果无线采集终端的当前系统时间位于AP接入点被配置的开放接入时段内，检测AP接入点的当前接入的终端数量是否超过AP接入点指定的最大终端接入数量；
如果AP接入点的当前接入的终端数量未超过AP接入点指定的最大终端接入数量，无线采集终端建立与AP接入点之间的无线连接，并且将该某一位置和水质数据上报给AP接入点，由AP接入点将该某一位置和水质数据进行加密后发送给物联网数据分析系统。
本发明实施例中，由AP接入点将该某一位置和水质数据进行加密后发送给物联网数据分析系统可以避免无线采集终端直接与物联网数据分析系统建立较长距离的通信连接，从而可以避免无线采集终端直接与物联网数据分析系统通信带来的较大功耗。
作为一种可选的实施方式，AP接入点将该某一位置和水质数据进行加密后发送给物联网数据分析系统的方式可以为：
AP接入点判断AP接入点的当前工作负荷是否超过AP接入点的最大工作负荷，如果未超过，AP接入点可以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；以及，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即时天气信息；以及，将该某一位置对应的即时天气信息、该某一位置和水质数据加密成数据元发送给物联网数据分析系统。

如前面所描述的，AP接入点可以将该某一位置对应的即时天气信息、该某一位置和水质数据加密成数据元发送给物联网数据分析系统，相应地，上述步骤202中，物联网数据分析系统对水质数据进行分析，在分析出水质数据超标时，物联网数据分析系统可以进一步分析该水质数据超标是否与该某一位置对应的即时天气信息相关，如果分析出该水质数据超标与该某一位
置对应的即时天气信息不相关，那么物联网数据分析系统可以根据接入物联网数据分析系统的各个车辆的无线车载终端上报的车辆即时位置进行大数据分析，确定出与该某一位置之间的距离小于指定距离的目标车辆。在实践中，由即时天气信息引起的水质数据超标的严重性通常要比由非即时天气信息引起的水质数据超标的严重性要大，因此，物联网数据分析系统在分析出该水质数据超标与该某一位置对应的即时天气信息不相关时，可以根据接入物联网数据分析系统的各个车辆的无线车载终端上报的车辆即时位置进行大数据分析，确定出与该某一位置之间的距离小于指定距离的目标车辆，以实现利用无线车载终端进行及时、广泛的水质数据超标告警，以减少给城市造成的灾害。
本发明实施例中，物联网数据分析系统可以从接入物联网数据分析系统的各个车辆的无线车载终端上报的车辆即时位置中，先确定出目标车辆即时位置，其中，该目标车辆即时位置与该某一位置之间的距离小于指定距离(如1公里)；进一步地，物联网数据分析系统从将上报该目标车辆即时位置的无线车载终端所在的车辆作为目标车辆。

204、物联网数据分析系统检测目标车辆上的无线车载终端已开启的水质数据超标告警信息接收功能是否配置有信息接收允许时段，如果配置有，执行步骤205；如果未配置有，直接执行步骤206。
205、物联网数据分析系统识别物联网数据分析系统的当前系统时间是否位于信息接收允许时段内，如果是，执行步骤206；如果否，结束本流程。
206、物联网数据分析系统向目标车辆上的无线车载终端下发水质数据超标告警信息，该水质数据告警信息包括该某一位置。
本发明实施例中，实施上述步骤203～步骤206，可以防止水质数据告警信息对一些未开启水质数据超标告警信息接收功能、或者已开启水质数据超标告警信息接收功能但物联网数据分析系统的当前系统时间不在水质数据超标告警信息接收功能配置有的信息接收允许时段内的无线车载终端造成干

本发明实施例中，由AP接入点将该某一位置和水质数据进行加密后发送给物联网数据分析系统可以避免无线采集终端直接与物联网数据分析系统建立较长距离的通信连接，从而可以避免无线采集终端直接与物联网数据分
析系统通信带来的较大功耗。
作为一种可选的实施方式，AP接入点将该某一位置和水质数据进行加密后发送给物联网数据分析系统的方式可以为：
AP接入点判断AP接入点的当前工作负荷是否超过AP接入点的最大工作负荷，如果未超过，AP接入点可以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；以及，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即时天气信息；以及，将该某一位置对应的即时天气信息、该某一位置和水质数据加密成数据元发送给物联网数据分析系统。

如前面所描述的，AP接入点可以将该某一位置对应的即时天气信息、该某一位置和水质数据加密成数据元发送给物联网数据分析系统，相应地，上述步骤202中，物联网数据分析系统对水质数据进行分析，在分析出水质数据超标时，物联网数据分析系统可以进一步分析该水质数据超标是否与该某一位置对应的即时天气信息相关，如果分析出该水质数据超标与该某一位置对应的即时天气信息不相关，那么物联网数据分析系统可以根据接入物联网数据分析系统的各个车辆的无线车载终端上报的车辆即时位置进行大数据分析，确定出与该某一位置之间的距离小于指定距离的目标车辆。在实践中，由即时天气信息引起的水质数据超标的严重性通常要比由非即时天气信息引起的水质数据超标的严重性要大，因此，物联网数据分析系统在分析出该水质数据超标与该某一位置对应的即时天气信息不相关时，可以根据接入物联网数据分析系统的各个车辆的无线车载终端上报的车辆即时位置进行大数据分析，确定出与该某一位置之间的距离小于指定距离的目标车辆，以实现利
