无线终端可以识别无线终端所在车辆的驾驶员的情绪是否稳定，如果情绪不稳定，无线终端可以提示驾驶员停车；如果情绪稳定，无线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停车并向无线终端输入停车位搜索指令，而无线终端可以在其所在车辆停车时输出停车位分布图，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，无线终端识别无线终端所在车辆的驾驶员的情绪是否稳定的方式可以为：
无线终端检测无线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，无线终端可以检测无线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，无线终端可以检测无线终端是否与无线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，无线终端可以通知无线终端所在车辆的驾驶员佩戴的穿戴设备向无线终端发送驾驶员的心电图数据；
以及，无线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，无线终端可以根据频域指标、时域指标及非线性指标，分析该驾驶员的情绪的活力值；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，根据活力值识别该驾驶员的情绪是否不 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，无线终端向停车位管理平台上报针对目标停车位的第一预约请求的方式可以为：
无线终端扫描周围环境中是否预先设置有转发节点，如果预先设置有转发节点，检测转发节点的当前接入的终端数量是否超过转发节点指定的最大终端接入数量；如果转发节点的当前接入的终端数量未超过转发节点指定的最大终端接入数量，无线终端建立与转发节点之间的无线连接，并且向转发节点上报针对目标停车位的第一预约请求，由转发节点将针对目标停车位的第一预约请求进行加密后发送给停车位管理平台。
更进一步地，无线终端扫描周围环境中预先设置有转发节点之后，无线终端可以检测转发节点是否被配置有开放接入时段，如果转发节点被配置有开放接入时段，识别无线终端的当前***时间是否位于转发节点被配置的开放接入时段内；如果无线终端的当前***时间位于转发节点被配置的开放接入时段内，才检测转发节点的当前接入的终端数量是否超过转发节点指定的最大终端接入数量。
本发明实施例中，由转发节点将针对目标停车位的第一预约请求进行加密后发送给停车位管理平台可以避免无线终端直接与停车位管理平台建立较长距离的通信连接，从而可以避免无线终端直接与停车位管理平台通信带来的较大功耗。
202、停车位管理平台向目标停车位所属用户的用户终端下发针对目标停车位的第二预约请求，该第二预约请求包括该车辆标识和该停车时长。
203、停车位管理平台在收到目标停车位所属用户的用户终端上报的、由目标停车位所属用户根据该车辆标识和该停车时长输入的单位时间内的停车收费值时，将该单位时间内的停车收费值下发给无线终端进行确认。
本发明实施例中，目标停车位所属用户可以根据该车辆标识和该停车时长，向用户终端输入单位时间内的停车收费值，由用户终端将该单位时间内的停车收费值下发给无线终端进行确认。其中，目标停车位所属用户向用户终端输入的单位时间内的停车收费值可以与该停车时长成反比关系。
204、停车位管理平台在收到无线终端上报的用于指示确认预约目标停车位的指示消息时，生成当前车辆位置与目标停车位之间的停车引导路径并发送给无线终端进行停车引导。
如图3所示，无线终端可以显示停车引导***发送的目标停车位与当前车辆位置之间的停车引导路径，并按照停车引导路径进行停车引导，使得驾驶员可以在停车引导路径的引导下将车辆开至目标停车位进行停放。
205、停车位管理平台判断停车位管理平台的当前工作负荷是否超过停车位管理平台指定的工作负荷，如果超过，直接执行步骤207；如果未超过，执行步骤206～步骤207。
206、停车位管理平台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目标停车位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目标停车位对应的预设时长(如1日)的天气信息。
其中，实施步骤204和步骤206，可以使得驾驶员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。
207、停车位管理平台在无线终端所在车辆使离目标停车位时，根据单位时间内的停车收费值和无线终端所在车辆在目标停车位的实际停车时间，从无线终端对应的支付账号中扣除相应的停车费用至用户终端对应的收费账号。
作为一种可选的实施方式，停车位管理平台可以判断无线终端所在车辆在目标停车位的实际停车时间是否小于或等于上述停车时长，如果是，停车位管理平台可以计算单位时间内的停车收费值和无线终端所在车辆在目标停车位的实际停车时间的乘积作为相应的停车费用；如果否，停车位管理平台可以计算单位时间内的停车收费值、无线终端所在车辆在目标停车位的实际停车时间以及加权系数三者的乘积作为相应的停车费用，其中，该加权系数为大于1的预设系数；进一步地，停车位管理平台可以从无线终端对应的支付账号中扣除相应的停车费用至用户终端对应的收费账号。
其中，实施这种可选的实施方式，可以鼓励驾驶员在其车辆停放时长到达上述停车时长时及时的将车辆驶离目标停车位，从而不仅有利于提升停车位预约的信用度，而且还可以避免导致巨额的停车费用。
可见，实施图2所描述的方法，能够使驾驶员便捷的查找到停车位进行停车，提高停车效率；还可以使驾驶员提前预知停车位对应的预设时长的天气信息，从而可以提前做好停车时的车辆防护准备，防止车辆被恶劣天气造成损伤。
可见，实施图2所描述的方法，能够实现无人停车收费，从而可以提高收费效率；而且，还可以实现无人停车引导，从而可以提高停车位的利用率。
可见，实施图2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，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。
可见，实施图2所描述的方法，可以避免无线终端直接与停车位管理平台通信带来的较大功耗。
