具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例提供一种定位方法。
请参阅图1，是本发明提供的定位方法的一个实施例的流程示意图，所述定位方法包括如下步骤：
S11、在需要对定位设备进行定位时，判断是否需要更新所述定位设备的当前位置；
S12、在需要更新所述定位设备的当前位置时，开启所述定位设备上的GPS定位模块；
S13、获取所述定位设备中的WIFI模块搜索到的当前所述定位设备附近的WIFI热点数据；
S14、控制所述定位设备中的GSM模块将所述WIFI热点数据上传到定位服务器，以使所述定位服务器根据所述WIFI热点数据获取第一位置信息，并在满足预设条件时根据所述第一位置信息更新所述定位设备的当前位置以及返回停止GPS定位命令；所述预设条件为所述定位服务器能够根据所述第一位置信息判定所述定位设备位于室内，或所述定位服务器能够根据所述第一位置信息判定所述定位设备位于室外且所述第一位置信息的定位精度小于预设的精度阈值；
S15、在获取到所述定位服务器返回的停止GPS定位命令时，关闭所述GPS定位模块；
S16、当通过所述GPS定位模块获取到第二位置信息时，关闭所述GPS定位模块，并将所述第二位置信息发送到所述定位服务器，使所述定位服务器根据所述第二位置信息更新所述定位设备的当前位置。
其中，WIFI热点数据包括WIFI热点的名称SSID、MAC地址和WIFI信号强度。
其中，定位服务器包括定位设备服务器和WIFI定位服务器。WIFI定位服务器指的是由WIFI定位服务商提供的服务器，WIFI定位服务器中收录了一个庞大的WIFI信息数据库，用以完成WIFI定位。
步骤S14中，定位服务器根据WIFI热点数据获取第一位置信息的工作过程具体为，定位设备服务器接收WIFI热点数据并转发到WIFI定位服务器，WIFI定位服务器将接收到的各个WIFI热点的名称SSID和MAC地址与WIFI信息数据库中已存储的数据进行匹配，并结合各个WIFI的信号强度进行相关的算法运算，以生成WIFI定位结果数据，并将该定位结果数据返回给定位设备服务器。其中，WIFI定位结果数据中包括WIFI定位是否成功信息、以及在WIFI定位成功情况下，定位设备当前所处位置的经纬度信息和定位精度，该经纬度信息即为第一位置信息。
步骤S14中，定位服务器在满足预设条件时根据第一位置信息更新定位设备的当前位置的工作过程具体为，定位设备服务器接收WIFI定位服务器返回的WIFI定位结果数据，并将该结果数据中的经纬度信息导入服务器的地图中，即可得到该经纬度对应的一个位置，进而可得知该位置是室内还是室外，当判定位于室内，或者位于室外且第一位置信息的定位精度小于预设的精度阈值时，定位设备服务器将第一位置信息对应的位置作为定位设备的当前位置。其中，将经纬度信息导入地图进而判断一个位置是在室内还是室外，例如，根据经纬度信息得到一个位置，如果该位置是一栋大楼所在的位置，即可判定定位设备在室内。另外，通常预设精度阈值为100米，默认当WIFI定位精度小于100米时则认为定位精度足够，反之类推，此处不加赘述。这种通过WIFI定位服务器来判断当前位置是否处于室内的方式提高了判断定位设备是否位于室内准确性，相应的，也有效地提高了本发明实施例中定位设备服务器下发停止GPS定位命令的准确性。
步骤S16中，需要说明的是，自定位设备开启GPS定位模块后，期间不论WIFI定位情况如何，一旦检测到GPS定位模块获取到了定位设备当前的位置信息，即第二位置信息，则当即关闭GPS定位模块，并以第二位置信息更新定位设备的当前位置，结束本次定位。另外，自定位设备开启GPS定位模块后，若定位设备一直没有接收到定位设备服务器下发的停止GPS定位命令，则继续执行GPS定位，直到通过GPS定位模块获取到定位设备的当前位置信息后，结束本次定位，或者，在接收到定位设备服务器下发的控制指令后，再转而执行相应的操作。
需要说明的是，打开WIFI模块后，经过短时间即可获取到当前定位设备附近的WIFI热点数据，因此，在本发明实施例中，在WIFI模块的开启时长达到预设的时间阈值时，自动关闭WIFI模块。优选地，预设的时间阈值为5s。另外，若因为周围的环境因素导致WIFI 模块没有在预设的时间内完成WIFI热点数据获取任务，则定位设备服务器控制定位设备的WIFI模块进行复位并重新工作，或者，由定位设备自检，在检测到出现异常时自主控制WIFI模块进行复位并重新工作。若出现连续预设次数的失败，则直接跳过WIFI定位过程，优选地，预设次数值为2次。
需要说明的是，定位设备与定位设备服务器之间的数据传输任务都由定位设备中的GSM模块完成。
本发明实施例通过在需要更新定位设备的当前位置时，开启GPS定位模块，并获取定位设备附近的WIFI热点数据以及将其上传到定位服务器，在定位服务器根据WIFI热点数据获取第一位置信息，进而根据第一位置信息判定定位设备当前位于室内或者位于室外且第一位置信息的定位精度小于预设的精度阈值时，关闭定位设备中的GPS定位模块。通常，当定位设备当前位于室内时，GPS定位模块是无法定位成功的，因此，在第一时间识别出无法进行GPS定位的环境情况，并且及时关闭GPS定位模块，能够有效地降低定位功耗，另外，当根据第一位置信息已经判定定位设备位于室外且第一位置信息的定位精度小于预设的精度阈值时，则不需要再利用GPS定位模块进行定位，及时关闭GPS定位模块，同样也能有效地降低定位功耗。
优选地，所述定位方法还包括：
获取所述定位服务器发送的位置更新成功消息，并记录获取的时刻；所述位置更新成功消息为所述定位服务器在更新所述定位设备的当前位置后生成的。
需要说明的是，定位服务器每次更新完定位设备的当前位置后都会生成对应的位置更新成功消息，并将该位置更新成功消息发送给定位设备，定位设备接收该位置更新成功消息并记录接收的时刻，以供下次准备对定位设备进行定位时判断是否需要更新定位设备的当前位置调用。
在一个优选的实施方式中，所述在需要对定位设备进行定位时，判断是否需要更新所述定位设备的当前位置，具体包括：
在需要对定位设备进行定位时，获取所述定位设备在最近一次获取到所述位置更新成功消息的时刻与当前时刻之间的移动距离；
比较所述移动距离和预设的距离阈值；并且，
在不存在所述移动距离或所述移动距离大于预设的距离阈值时，判定需要更新所述定位设备的当前位置。
需要说明的是，定位设备还包括姿态传感器模块，用于采集定位设备的姿态参数。结合位置更新成功消息和姿态参数，即可获知定位设备在最近一次获取到位置更新成功消息的时 刻与当前时刻之间的移动距离。在最近一次更新位置到当前时刻期间，若定位设备的移动距离小于预设的距离阈值，则没必要更新定位设备的位置信息，即重新进行一次定位，直接沿用最近一次更新的位置信息作为本次的位置信息即可；若不存在移动距离或者移动距离大于预设的距离阈值，则判定需要更新定位设备的位置信息。其中，不存在移动距离指的是没有获取到位置更新成功消息的情况，例如定位设备是初次使用，定位服务器在此之前并没有更新过定位设备的位置信息，那么，定位服务器将不会生成对应的位置更新成功消息。另外，移动距离大于预设的距离阈值则表示定位设备距离最近一次更新位置时刻，其位置已经发生了大的变动，最近一次更新的位置信息已经不适用于本次了，需要重新获取一个新的位置信息。这样的话，使用姿态传感器检测定位设备的姿态参数，进而调整定位策略，可优化定位间隔，即通过减少定位次数能有效的降低定位功耗。
在另一个优选的实施方式中，所述在需要对定位设备进行定位时，判断是否需要更新所述定位设备的当前位置，具体包括：
在需要对定位设备进行定位时，获取所述定位设备在最近一次获取到所述位置更新成功消息的时刻与当前时刻之间的移动距离；
将所述移动距离发送给定位服务器，以使所述定位服务器比较所述移动距离和预设的距离阈值，并在判定不存在所述移动距离或所述移动距离大于预设的距离阈值时返回需要更新位置命令；
在获取到所述需要更新位置命令时，判定需要更新所述定位设备的当前位置。
需要说明的是，本实施方式与上述实施方式的区别在于，在本实施方式中，比较移动距离和预设的距离阈值的任务由定位服务器完成。具体地，定位设备得到移动距离后，将移动距离发送给定位服务器，定位服务器执行比较任务；通常，定位服务器的数据处理能力要优于定位设备，因此，本实施方式能够提高数据处理速度，且能适用于数据运算量较大的场景。
优选地，所述定位方法还包括：
在获取到定位服务器发送的位置信息请求，或检测到定位设备内部的定时触发器触发时，判定需要对定位设备进行定位。
需要说明的是，定位设备开始一次定位的触发条件可以是以下情况中的任意一种或几种的任意组合，获取到定位服务器的位置信息请求而触发定位、检测到定位设备内部的定时触发器而触发周期性定位，即每次定时时间到了就触发一次定位、或者检测到的定位设备内部的姿态传感器采集的姿态数据的变化量超过了预设的姿态阈值而触发定位。
在一个优选的实施方式中，所述定位方法还包括：
当所述GPS定位模块的开启时长达到预设的第一时长阈值时，关闭所述GPS定位模块， 并向所述定位服务器发送GPS定位失败消息。
需要说明的是，在本实施方式中，在开启GPS定位模块的同时开始计时，若定位服务器一直没有向定位设备下发停止GPS定位指令，则GPS定位模块一直工作，直到GPS定位模块的开启时长达到预设的第一时间阈值时，就关闭GSP定位模块。通常，如果在当前环境下GPS定位模块能够定位成功，则在一定时间内就能够获取到定位设备的当前位置信息，因此，在定位超过一定时间但却又仍然无法获取到位置信息的情况下，哪怕是继续定位，其成功的可能性也极小，故而及时关闭GPS定位模块，能够有效的降低定位设备的定位功耗。优选地，预设第一时长阈值为2分钟。
在另一个优选的实施方式中，所述定位方法还包括：
当所述GPS定位模块的开启时长达到预设的第二时长阈值时，根据所述WIFI热点数据中的最大WIFI信号强度以及所述GPS定位模块的最大GPS信号强度判断所述定位设备是否位于室内；其中，所述第二时长阈值小于所述第一时长阈值；
在判定所述定位设备位于室内时，关闭所述GPS定位模块，并向所述定位服务器发送所述GPS定位失败消息。
需要说明的是，开启GPS定位模块后，若一直没有获取到定位设备的当前位置信息且又没有获取到定位服务器下发的停止GPS定位命令，那么，GPS定位模块将持续工作，直到达到第一时长阈值后，若还未获取到位置信息则关闭GPS定位模块，并返回GPS定位失败消息。在这个过程中，GPS定位模块仍存在较大的功耗。因此，增设一个第二时长阈值，在GPS定位模块的开启时长达到预设的第二时长阈值时，根据WIFI热点数据中的最大WIFI信号强度及GPS定位模块的最大GPS信号强度再次判断定位设备当前是否位于室内，如果位于室内则及时关闭GPS定位模块，能够有效的降低定位功耗。优选地，预设第二时长阈值为10秒。
进一步地，所述当所述GPS定位模块的开启时长达到预设的第二时长阈值时，根据所述WIFI热点数据中的最大WIFI信号强度以及所述GPS定位模块的最大GPS信号强度判断所述定位设备是否位于室内，具体为：
当所述GPS定位模块的开启时长达到预设的第二时长阈值时，判断是否满足所述WIFI热点数据中的最大WIFI信号强度大于预设的第一信号强度阈值且所述GPS定位模块的最大GPS信号强度小于预设的第二信号强度阈值；
若满足，则判定所述定位设备位于室内。
优选地，预设第一信号强度阈值为-70dbm，预设第二信号强度阈值为20。
在又一个优选地实施方式中，所述定位方法还包括：
所述定位方法还包括：
当所述GPS定位模块的开启时长达到预设的第三时长阈值时，根据所述GPS定位模块的搜星数目和最大GPS信号强度判断是否搜星失败；其中，所述第三时长阈值大于所述第二时长阈值且小于所述第一时长阈值；
在判定搜星失败时，关闭所述GPS定位模块，并向所述定位服务器发送所述GPS定位失败消息。
需要说明的是，开启GPS定位模块后，若一直没有获取到定位设备的当前位置信息且又没有获取到定位服务器下发的停止GPS定位命令，那么，GPS定位模块将持续工作，直到达到第二时长阈值后再次判断是否在室内，若仍判定不在室内，则继续工作，直到达到第一时长阈值后，若还未获取到位置信息则关闭GPS定位模块，并返回GPS定位失败消息。在这个过程中，GPS定位模块仍存在较大的功耗。因此，增设一个第三时长阈值，在GPS定位模块的开启时长达到第三时长阈值时，根据GPS定位模块的搜星数目和最大GPS信号强度判断是否搜星失败，以便于判断定位设备当前是否位于GPS定位情况差的室外位置或者窗边位置，在这种情况下，及时关闭GPS定位模块，能够有效的降低定位功耗。优选地，预设第三时长阈值为30秒。
进一步地，所述当所述GPS定位模块的开启时长达到预设的第三时长阈值时，根据所述GPS定位模块的搜星数目和最大GPS信号强度判断是否搜星失败，具体为：
当所述GPS定位模块的开启时长达到预设的第三时长阈值时，判断是否满足所述GPS定位模块的搜星数目小于预设的数目阈值并且所述GPS定位模块的最大GPS信号强度小于预设的第三信号强度阈值；
若满足，则判定搜星失败。
优选地，预设数目阈值为4，预设第三信号强度阈值为30。
需要说明的是，当GPS定位模块的开启时长在第二时长阈值到第一时长阈值期间，可以循环根据WIFI热点数据中的最大WIFI信号强度以及GPS定位模块的最大GPS信号强度判断定位设备是否位于室内，以及当开启时长在第三时长阈值到第一时长阈值期间，增加循环根据所述GPS定位模块的搜星数目和最大GPS信号强度判断是否搜星失败的任务。或者，每预设的周期判断一次，优选地，预设周期为1秒，即在GPS定位模块的开启时长在第二时长阈值到第一时长阈值期间，每秒判断一次定位设备当前是否位于室内，以及在开启时长达到第三时长阈值直到达到第一时长阈值期间，增加每秒判断是否搜星失败的任务。
在一个优选的实施方式中，所述定位方法还包括：
在获取所述定位设备中的WIFI模块搜索到的当前所述定位设备附近的WIFI热点数据 时，获取所述定位设备中的GSM模块搜索到的当前所述定位设备附近的基站信息数据；
在控制所述定位设备中的GSM模块将所述WIFI热点数据上传到定位服务器时，控制所述定位设备中的GSM模块将所述基站信息数据上传到所述定位服务器；
所述GPS定位失败消息用于通知所述定位服务器根据所述第一位置信息更新所述定位设备的当前位置，或在不存在所述第一位置信息时根据所述基站信息数据获取第三位置信息并根据所述第三位置信息更新所述定位设备的当前位置。
其中，基站信息数据包括国家编码、运行商编码、小区号、基站编码和基站信号强度等。
需要说明的是，在本实施方式中，增加基站定位来辅助完成定位工作，在WIFI定位和GPS定位都没有获取到定位设备的位置信息的情况下，则可以根据基站定位获取到的定位设备的位置信息更新定位设备的当前位置。
需要说明的是，在定位过程中，如果GPS定位、WIFI定位和基站定位都没有获得定位设备的当前位置信息，那么就确认本次定位彻底失败，定位服务器将通知定位设备再次定位。
