具体的，在该实施例中，如图1所示，在步骤110之前，还可以包括：
101、智能终端提交停车请求。
上述实施例中，智能终端会发送包含用户预停车的目标停车场信息的停车请求，根据停车请求或对目标停车场内存在的空余车位进行查询，对存在的空余车位进行筛选，选择最终目标空余车位，目标空余车位的选择具体可以为：目标停车场内空余车位数量大于等于3，空余车位数量满足停车需求，且距离目标停车场入口距离最近的至少一个空余车位。并为目标空余车位执行停车行进路线，还会将最优停车行进路线发送至提交停车请求的智能终端，为用户提供引导。上述方法很好的实现了 对目标空余车位的查询和最优停车行进路线的制定，方便了用户的停车，减少了由于寻找车位浪费的时间。
在图1对应的基于物联网的停车方法实施例的基础上，还进行了以下改进，具体如图2所示。图2为本发明实施例提供的另一种基于物联网的停车方法的示意性信令交互图。具体执行步骤如下：
110、获取用户通过智能终端发送的停车请求，其中所述停车请求中包括用户预停车的目标停车场信息；
120、根据接收到的所述停车请求，查询所述目标停车场内存在的空余车位；
131、对所述空余车位进行统计；
具体的，统计停车场内空余车位的数量以及对应的位置信息。
132、选择所述目标停车场内与所述目标停车场入口距离最近的至少一个空余车位；
在距离所述目标停车场入口最近的至少一个空余车位中，选择转弯次数最少的至少一个空余车位为目标空余车位；
具体的，对存在的空余车位的位置信息进行筛选，选择空余车位至停车场入口行进距离最短的车位为目标空余车位。
其中，至少一个目标空余车位可以为对称设置在停车场入口两侧的空余车位，也可以是与停车场入口之间的距离相同的多个空余车位，从存在的空余车位中选择目标空余车位。
在步骤132执行以后还需要执行步骤133、为目标空余车位制定停车行进路线，并确定最优停车行进路线；
140、将所述最优停车行进路线发送至所述智能终端，以便所述用户能够根据所述智能终端显示的最优停车行进路线，到达所述目标空余车位。
上述实施例中，将目标停车场内距离目标停车场入口最近的至少一个空余车位选定为目标空余车位，使得用户能够更好更快的将车辆停靠，停靠车辆更加的方便，同时也节省了停靠车辆的时间。
在图2对应实施例的基础上，进行了改进，具体如图3所示。图3为本发明实施例提供的另一种基于物联网的停车方法的示意性信令交互图。具体步骤如下：
110、获取用户通过智能终端发送的停车请求，其中所述停车请求中包括用户预停车的目标停车场信息；
120、根据接收到的所述停车请求，查询所述目标停车场内存在的空余车位；
131、对空余车位进行筛选；
具体的，初步统计停车场内空余车位的数量以及对应的位置等，方便对目标空余车位的选择。
132、选择所述目标停车场内与所述目标停车场入口距离最近的至少一个空余车位；
在距离所述目标停车场入口最近的至少一个空余车位中，选择转弯次数最少的 至少一个空余车位为目标空余车位；
其中，至少一个目标空余车位可以为对称设置在停车场入口两侧的空余车位，也可以是具体停车场入口行程相同的多个空余车位，从存在的空余车位中选择目标空余车位。
1331、根据所述用户的当前位置信息和所述目标停车场的位置信息，确定所述用户的当前位置至所述目标停车场的最优停车场行进路线；其中，所述最优停车场行进路线为当前位置信息至所述目标停车场位置行车距离最近，耗时最短的行车路线；
并根据所述目标空余车位的位置以及目标停车场的入口位置分别制定车位行进路线，其中，所述车位行进路线为所述目标停车场的入口至所述目标空余车位的行进路线，在制定的车位行进路线中选择拐弯次数最少、行进距离最短的车位行进路线为最优车位行进路线。
当存在距离停车场入口最近，且对称设置在停车场入口两侧的空余车位置时，会制定两条行车路线，从中随机选择一条作为最优停车行进路线，另外的一条也会被选择作为备选最优停车行进路线；当存在距离停车场入口最近，距离相同，且不对称设置在停车场入口两侧的空余车位置时，会为距离停车场入口最近且距离相同的多个空余车位制定停车行进路线，并从制定的停车行进路线中选择拐弯最少、最能够直接到达目标空余车位的停车行进路线作为最优停车行进路线。比方说，有3个距离停车场入口最近的空余车位，从停车场入口行进至3个不同的空余车位分别需要拐弯2、3和4次，会从中选择拐弯2次的空余车位为目标空余车位，为选定的目标空余车位制定行车路线。
140、将所述最优停车行进路线发送至所述智能终端，以便所述用户能够根据所述智能终端显示的最优停车行进路线，到达所述目标空余车位。
在上述实施例中，将最优停车行进路线分为最优停车场行进路线和最优车位行进路线，并分别制定最优停车场行进路线和最优车位行进路线，有效提高了最优行进路线选择制定的效率，最优行进路线制定的更有针对性，为最优停车行进路线的选择提供了更好的支持，减少了停车行进的路程，节约了用户的时间。
在基于物联网的停车方法实施例的基础上，还进行了改进，具体如图4和图5所示。图4为本发明实施例提供的另一种基于物联网的停车方法的示意性信令交互图，图5为本发明实施例提供的基于物联网的停车方法中确定目标空余车位的逻辑判断图。具体步骤如下：
110、获取用户通过智能终端发送的停车请求，其中所述停车请求中包括用户预停车的目标停车场信息；
120、根据接收到的所述停车请求，查询所述目标停车场内存在的空余车位。
如果所述目标停车场没有空余停车位时，则可以执行如下步骤：
1201、对目标停车场周边的停车场进行筛选，筛选以所述目标停车场为中心，预设距离为半径的区域范围内所有停车场；
1202、统计所述以所述目标停车场为中心，预设距离为半径的区域范围内所有停车场内空余车位的数量，确定所述以所述目标停车场为中心，预设距离为半径的区域范围内所有停车场中空余车位的数量最多的停车场为最优停车场；
具体的，统计预设半径范围内所有的停车场中每一个停车场内存在的空余车位数量，从中选择空余车位最多的停车场最为最优停车场；
1203、对选定的最优停车场内的空余车位进行筛选，选择目标空余车位，并确定最优停车行进路线；
具体的，会在最优停车场内选择距离最优停车场入口最近的的停车位最为目标空余车位，其中，目标空余车位可以为对称设置在停车场入口两侧的空余车位，也可以是具体停车场入口行程相同的多个空余车位，从存在的空余车位中选择目标空余车位。
140、将所述最优停车行进路线发送至所述智能终端，以便所述用户能够根据所述智能终端显示的最优停车行进路线，到达所述目标空余车位。
上述实施例，在执行步骤120后，还会对目标停车场内的空余车位的数量进行统计，根据统计的数量判断目标停车场内的空余车位是否满足停车需求。具体可以为，对目标停车场内空余车位的数量进行判断，当空余车位数量大于等于3时，空余车位数量满足停车需求，会将目标停车场定为最优停车场，在空余车位进行筛选，选择所述目标停车场内与所述目标停车场入口距离最近的至少一个目标空余车位，为选定的目标空余车位规划行车路线图，对规划的行车路线图进行选择，确定最优行车路线。其中，车位行进路线为所述目标停车场的入口至所述目标空余车位的最优行进路线。当小于3时，以目标停车场为圆心，筛选预设半径内的所有停车场，并对预设半径内空余车位的数量进行统计，选择空余车位最多且大于3的停车场为最优停车场。后续重新对重新选定的最优停车场内的目标空余车位进行选择，并制定最优停车行进路线。
具体的，预设半径的范围可以为固定值3公里或5公里，当预设半径为固定值时，服务器只会对目标停车场周边固定范围内的停车场内空余车位的数量进行统计，从统计到的符合要求的停车场内选择最优停车场，为最优停车场内的目标空余车位制定行进路线，并选择最优停车行进路线。
当目标停车场和预设半径内的停车场均不满足停车需求时，会在目标停车场预设半径内包括目标停车场在内的所有停车场的空余车位的数量进行统计和比对，最终确定空余车位最多的停车场为最优停车场，并从最优停车场内选择目标空余车位制定停车行进路线。
在上述实施例的基础上，还进行了改进，具体如图6所示，图6为本发明实施例提供的另一种基于物联网的停车方法的示意性信令交互图。具体执行步骤如下：
110、获取用户通过智能终端发送的停车请求，其中所述停车请求中包括用户预停车的目标停车场信息；
120、根据接收到的所述停车请求，查询所述目标停车场内存在的空余车位；
1201、对目标停车场周边的停车场进行筛选，筛选以所述目标停车场为中心，预设距离为半径的区域范围内所有停车场；

在执行步骤160后，还会重复执行步骤140，以便能够将更新后的最优停车行进路线发送至智能终端，为用户提供指引。
在上述实施例中，步骤150能够实时对目标停车场内的空余车位信息进行更新，在更新后的空余车位中选择距离停车场入口距离最近的目标空余车位，为目标空余车位制定停车行进路线图，步骤160会从更新后的停车行进路线图中选择更新后的最优停车行进路线图，通过会实时对目标停车场内的空余车位信息、最优停车行进路线等进行更新，以便用户能够实时得到最新的最优停车行进路线，避免车已开到，已选择空余车位被占，没有地方停车或需要重新查找空余车位情况的发生。

在上述实施例中，将最优停车行进路线分为最优停车场行进路线和最优车位行进路线，并对最优停车场行进路线和最优车位行进路线分开制定，能够更好的确定最优停车行进路线，保证最优、最快的到达目标空余车位，减少到达目标空余车位的时间。

上述实施例，通过对停车场内车位的状态信息进行判断、统计和存储，方便了后续对目标停车场以及目标停车场内空余车辆的查询和最优停车行进路线的制定。
上文结合图1至图7详细描述了本发明提供的基于物联网的停车方法，下面结合图8对本发明提供的基于物联网的停车系统进行详细的描述。
如图8所示，图8为本发明实施例提供的基于物联网的停车系统的结构示意图。其中，服务器包括获取单元、查询单元、处理单元、发送单元以及更新单元，各单元执行的具体操作会在后续实施例中详细论述。
具体的：

本发明实施例提供的基于物联网的停车系统中所包括的各功能单元所执行的功能均已在图1至图7对应的方法实施例中做了详细介绍，因此这里将不再赘述。
本发明实施例提供的基于物联网的停车系统的查询单元会根据获取单元获取到的停车请求或对目标停车场内存在的空余车位进行查询，处理单元会对存在的空余车位进行筛选，选择最终目标空余车位，并为目标空余车位执行停车行进路线，发送单元会将最优停车行进路线发送至提交停车请求的智能终端，为用户提供引导。上述系统很好的实现了对目标空余车位的查询和最优停车行进路线的制定，方便了用户的停车，减少了由于寻找车位浪费的时间。
在上述实施例的基础上，还进行了以下改进：

进一步，目标停车场内与所述目标停车场入口距离最近的目标空余车位不止1个，当为一个时，将唯一的一个空余车位选定为目标空余车位；当大于1个时，分别为满足条件的空余车位制定停车行车路线，从制定的停车行进路线中选择最优的，当存在多条最优停车行进路线时，将满足条件的停车行进路线同时发送给智能终端，由用户自己进行选择。
当存在距离停车场入口最近，且对称设置在停车场入口两侧的空余车位置时，会制定单条行车路线，从中随机选择一条作为最优停车行进路线，另外的一条也会被选择作为备选最优停车行进路线；当存在距离停车场入口最近，距离相同，且不对称设置在停车场入口两侧的空余车位置时，会为距离停车场入口最近且距离相同的多个空余车位制定停车行进路线，并从制定的停车行进路线中选择拐弯最少、最能够直接到达目标空余车位的停车行进路线作为最优停车行进路线。比方说，有3个距离停车场入口最近的空余车位，从停车场入口行进至3个不同的空余车位分别需要拐弯2、3和4次，会从中选择拐弯2次的空余车位为目标空余车位，为选定的目标空余车位制定行车路线。
上述实施例中空余车位进行筛选，选择目标停车场内与目标停车场入口最近的至少一个目标空余车位，能够为用户提供最近最优的空余车位，节省停车的时间。
在基于物联网的停车系统实施例的基础上，还进行了以下改进：

根据所述用户的当前位置信息和所述目标停车场的位置信息，确定所述用户的 当前位置至所述目标停车场的最优停车场行进路线；其中，所述最优停车场行进路线为当前位置信息至所述目标停车场位置行车距离最近，耗时最短的行车路线；
并根据所述目标空余车位的位置以及目标停车场的入口位置分别制定车位行进路线，其中，所述车位行进路线为所述目标停车场的入口至所述目标空余车位的行进路线，在制定的车位行进路线中选择拐弯次数最少、行进距离最短的车位行进路线为最优车位行进路线；

发送单元，用于将所述最优停车行进路线发送至所述智能终端，以便所述用户能够根据所述智能终端显示的最优停车行进路线，到达所述目标空余车位。
在上述实施例中，服务器还会对目标停车场内的空余车位的数量进行统计，根据统计的数量判断是否需要重新选定停车场。具体可以为，对目标停车场内空余车位的数量进行判断，当空余车位数量大于等于3时，在空余车位进行筛选，选择所述目标停车场内与所述目标停车场入口距离最近的至少一个目标空余车位，为选定的目标空余车位规划行车路线图，对规划的行车路线图进行选择，确定最优行车路线。其中，车位行进路线为所述目标停车场的入口至所述目标空余车位的最优行进路线。当小于3时，以目标停车场为圆心，筛选预设半径内的所有停车场，并对预设半径内空余车位的数量进行统计，选择空余车位最多的停车场为最优停车场。后续重新对最优停车场内的目标空余车位进行选择，并执行最优停车行进路线。
具体的，预设半径的范围可以为固定值3公里或5公里，当预设半径为固定值时，服务器只会对目标停车场周边固定范围内的停车场内空余车位的数量进行统计，从统计到的符合要求的停车场内选择最优停车场，为最优停车场内的目标空余车位 制定行进路线，并选择最优停车行进路线。
当目标停车场和预设半径内的停车场均不满足停车需求时，会在目标停车场预设半径内包括目标停车场在内的所有停车场的空余车位的数量进行统计和比对，最终确定空余车位最多的停车场为最优停车场，并从最优停车场内选择目标空余车位制定停车行进路线。
在上述所有实施例的基础上，对基于物联网的停车系统还进行了改进，基于物联网的停车系统还包括更新单元，具体如下：

处理单元，根据目标空余车位的位置信息和目标停车场入口位置制定行车时长最短的行车路径为最优车位行进路线。
在上述实施例中，将最优停车行进路线分为最优停车场行进路线和最优车位行进路线，并对最优停车场行进路线和最优车位行进路线分开制定，能够更好的确定最优停车行进路线，保证最优、最快的到达目标空余车位，减少到达目标空余车位的时间。
如图9和图10所示，图9为本发明实施例提供的基于物联网的停车系统的应用场景图；图10为本发明实施例提供的基于物联网的停车系统的应用示意性框架图。具体如下：
车位信息反馈装置，用于对当前停车场内车位的状态信息进行判断；
中心管理平台，用于对接收到的所有空余车位的所述状态信息进行统计存储；其中，所述状态信息包括空余车位的位置信息；
服务器，用于获取用户通过智能终端发送的停车请求，其中所述停车请求中包括用户预停车的目标停车场信息；
根据接收到的所述停车请求，查询所述目标停车场内存在的空余车位；
对所述空余车位进行筛选，选择所述目标停车场内与所述目标停车场入口距离最近的至少一个目标空余车位，为目标空余车位制定停车行进路线，并确定最优停车行进路线；
将所述最优停车行进路线发送至所述智能终端，以便所述用户能够根据所述智能终端显示的最优停车行进路线，到达所述目标空余车位。
在上述实施例中，通过事先对停车场内空余车位信息进行查询和存储，在接收到停车请求后可以直接读取已存储的空余车位信息，不需要临时再进行查询等操作，提高了对空域车辆的查询以及最优停车行进路线制定的效率。
