请参阅图3，图3是本发明实施例公开的另一种基于数据分析的停车引导方 法的流程示意图。如图3所示，该基于数据分析的停车引导方法可以包括以下步骤：
301、无线通信终端将无线通信终端所在车辆的当前车辆位置以及驾驶员输入的期望停车时长上报给停车引导系统。
作为一种可选的实施方式，无线通信终端将无线通信终端所在车辆的当前车辆位置以及驾驶员输入的期望停车时长上报给停车引导系统之前，无线通信终端还可以执行以下步骤：
无线通信终端响应无线通信终端所在车辆的驾驶员输入的停车位搜索指令，采集当前车辆位置；以及，无线通信终端可以提示驾驶员输入期望停车时长；以及，无线通信终端检测驾驶员输入的期望停车时长(如1个小时)。
作为一种可选的实施方式，无线通信终端在响应无线通信终端所在车辆的驾驶员输入的停车位搜索指令，采集当前车辆位置之前，还可以执行以下步骤：
无线通信终端可以识别无线通信终端所在车辆的驾驶员的情绪是否稳定，如果情绪不稳定，无线通信终端可以提示驾驶员停车；如果情绪稳定，无线车载终端可以每隔指定时间采集一帧驾驶员的人脸图像，并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，提示驾驶员停车；相应地，驾驶员可以根据提示向无线通信终端输入停车位搜索指令，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驾驶事故。
本发明实施例中，无线通信终端识别无线通信终端所在车辆的驾驶员的情绪是否稳定的方式可以为：
无线通信终端检测无线通信终端所在车辆的驾驶员佩戴的穿戴设备(如手环)发送的驾驶员的心电图数据；举例来说，无线通信终端可以检测无线通信终端所在车辆的行驶时长是否超过预设时长，如果超过预设时长，无线通信终端可以检测无线通信终端是否与无线通信终端所在车辆的驾驶员佩戴的穿戴设备(如手环)建立通讯连接，如果是，无线通信终端可以通知驾驶员佩戴的穿戴设备向无线通信终端发送驾驶员的心电图数据；
以及，无线通信终端可以对心电图数据进行去噪处理，并采用心电图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，以及计算经过去噪处理的心电图数据中相邻R波之间RR间距；以及，计算RR间距的频域指标、时域指标及非线性指标；其中，频域指标包括副交感神经活性指标，时域指标包括短程心率变动性指标；短程心率变动性指标通过获取RR间距差值平方和的均方根来 计算；副交感神经活性指标通过快速傅里叶变换来计算；非线性指标通过分形维数计算方法来计算；
以及，无线通信终端可以根据频域指标、时域指标及非线性指标，分析该用户的情绪的活力值；其中，活力值为根据时域指标、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；以及，根据活力值识别该用户的情绪是否不稳定。
本发明实施例中，实施上述实施方式可以精确的识别出驾驶员的情绪是否稳定。
作为一种可选的实施方式，无线通信终端将无线通信终端所在车辆的当前车辆位置以及驾驶员输入的期望停车时长上报给停车引导系统的方式可以为：
无线通信终端扫描周围环境中是否预先设置有路由节点，如果预先设置有路由节点，检测路由节点是否被配置有开放接入时段，如果路由节点被配置有开放接入时段，识别无线通信终端的当前系统时间是否位于路由节点被配置的开放接入时段内；
如果无线通信终端的当前系统时间位于路由节点被配置的开放接入时段内，检测路由节点的当前接入的终端数量是否超过路由节点指定的最大终端接入数量；
如果路由节点的当前接入的终端数量未超过路由节点指定的最大终端接入数量，无线通信终端建立与路由节点之间的无线连接，并且将无线通信终端所在车辆的当前车辆位置以及驾驶员输入的期望停车时长发送给路由节点，由路由节点将无线通信终端所在车辆的当前车辆位置以及驾驶员输入的期望停车时长发送给停车引导系统。
本发明实施例中，由路由节点将无线通信终端所在车辆的当前车辆位置以及驾驶员输入的期望停车时长发送给停车引导系统可以避免无线通信终端直接与停车引导系统建立较长距离的通信连接，从而可以避免无线通信终端直接与停车引导系统通信带来的较大功耗。
302、停车引导系统在自身管辖范围内查找出存在有空闲停车位、并且该空闲停车位的剩余出租时长超过该期望停车时长的所有停车场；以及，计算查找出的每一个停车场的入口位置与所述当前车辆位置之间的距离值发送给所述无线车载终端，以使所述无线车载终端所在车辆的驾驶员以所述每一个停车场的入口位置与所述当前车辆位置之间的距离值为依据，从所述所有停车场中选择一个停车场作为目标停车场。
303、停车引导系统生成目标停车场的入口位置与当前车辆位置之间的外部 引导路径，将所述外部引导路径和目标停车位在所述目标停车场中的位置信息发送给所述无线通信终端进行停车引导，目标停车位是目标停车场内的剩余出租时长超过该期望停车时长任意一个空闲停车位。
304、停车引导系统判断停车引导系统的当前工作负荷是否超过停车引导系统指定的工作负荷，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平台发起包括目标停车位的天气信息查询请求；以及，接收天气服务平台通过天气信息查询端口返回的目标停车位对应的预设时长(如1日)的天气信息。
305、停车引导系统将目标停车位对应的预设时长的天气信息下发给无线通信终端。
其中，实施步骤304和步骤305，驾驶员可以提前预知目标停车位对应的预设时长(如1日)的天气信息，从而可以做好停车时的车辆防护准备，以免车辆被恶劣天气造成损伤。
306、停车引导系统判断车辆在目标停车位的实际停车时长是否超过期望停车时长，如果未超过，按照目标停车位对应的第一收费规则以及实际停车时长计算相应的停车费用，第一收费规则包括单位时间对应的第一收费金额；如果超过期望停车时长，按照目标停车位对应的第二收费规则以及实际停车时长计算相应的停车费用，第二收费规则包括单位时间对应的第二收费金额，并且第二收费金额等于n倍的第一收费金额，n为大于0的正数；以及，从无线通信终端绑定的电子账号中扣除所述相应的停车费用。
其中，实施步骤306可以鼓励车主在其车辆停放时长到达期望停车时长时，及时将车辆驶离目标停车位置，以免导致巨额的停车费用。
可见，实施图3所描述的方法，可以将车辆引导至适合驾驶员的期望停车时长的停车位，从而可以提高停车位的利用率。
可见，实施图3所描述的方法，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。
可见，实施图3所描述的方法，可以避免无线通信终端直接与停车引导系统通信带来的较大功耗。
