    所述无线终端，用于检测所述无线终端所在车辆的驾驶员佩戴的穿戴设备发送的所述驾驶员的心电图数据；对所述心电图数据进行去噪处理；采用心电图R波提取算法提取经过去噪处理的心电图数据中的R波峰值，以及计算所述经过去噪处理的心电图数据中相邻R波之间RR间距；计算所述RR间距的频域指标、时域指标及非线性指标；其中，所述频域指标包括副交感神经活性指标，所述时域指标包括短程心率变动性指标；所述短程心率变动性指标通过获取所述RR间距差值平方和的均方根来计算；所述副交感神经活性指标通过快速傅里叶变换来计算；所述非线性指标通过分形维数计算方法来计算；根据所述频域指标、时域指标及非线性指标，分析所述用户的情绪的活力值；所述活力值为根据所述时域指标、频域指标及非线性指标建立的多元线性回归方程计算得到的值；根据所述活力值识别所述驾驶员的情绪是否不稳定。
  9. 根据权利要求6～8任一项所述的可自选车位的停车导航路径生成系统，其特征在于，所述无线终端将包括所述无线终端所在车辆的当前车辆位置的停车 位搜索指令上报给大数据分析系统的方式具体为：
    所述无线终端，用于扫描周围环境中是否预先设置有路由节点，如果预先设置有所述路由节点，检测所述路由节点是否被配置有开放接入时段，如果所述路由节点被配置有所述开放接入时段，识别所述无线终端的当前系统时间是否位于所述路由节点被配置的所述开放接入时段内；如果所述无线终端的当前系统时间位于所述路由节点被配置的所述开放接入时段内，检测所述路由节点的当前接入的终端数量是否超过所述路由节点指定的最大终端接入数量；如果所述路由节点的当前接入的终端数量未超过所述路由节点指定的最大终端接入数量，建立与所述路由节点之间的无线连接，并且将包括所述无线终端所在车辆的当前车辆位置的停车位搜索指令发送给所述路由节点，由所述路由节点将包括所述无线终端所在车辆的当前车辆位置的停车位搜索指令发送给所述大数据分析系统。
  10. 根据权利要求6～9所述的可自选车位的停车导航路径生成系统，其特征在于，所述大数据分析系统查询所述目标停车位对应的预设时长的天气信息并下发给所述无线终端的方式具体为：
    所述大数据分析系统，用于判断所述大数据分析系统的当前工作负荷是否超过所述大数据分析系统指定的工作负荷，如果所述大数据分析系统的当前工作负荷未超过所述大数据分析系统指定的工作负荷，通过天气信息查询端口向所述天气信息查询端口对应的天气服务平台发起包括所述目标停车位的天气信息查询请求；接收所述天气服务平台通过所述天气信息查询端口返回的所述目标停车位对应的预设时长的天气信息；将所述目标停车位对应的预设时长的天气信息下发给所述无线终端。
