背景技术
电子定位设备是一种用于获取位置信息的终端设备。该终端设备能够通过全球定位***(Global Positioning System，GPS)，或者无线网络，或者基站辅助定位获取终端所处的地理位置信息。在获取到所处的地理位置信息之后，该终端设备能够通过网络将位置数据传输到智能手机等用户设备。智能手机等用户设备的用户就可以查看到电子定位设备所处的地理位置的信息。
现有技术中的电子定位设备主要是按照时间信息进行定位，到达预定时刻就采用定位模块进行定位，采用数据传输模块传输定位数据。但是，由于定位模块和数据传输模块的功率较高，所以现有技术中的电子定位设备的待机时间通常只有2-3天，最多的也只有一个星期。
而待机时间是评价电子定位设备的性能的一个主要方面。例如，对于设置在汽车上用于防盗的电子定位设备，如果待机时间小于一星期，则盗车者可以在偷盗成功后，将盗窃车辆放在信号屏蔽区域一星期，待电子定位设备的电量耗尽，再将盗窃车辆交易给买家。这是因为电子定位设备的待机时间短，盗车者只需将盗窃车辆存放较短时间，就可以使电子定位设备电量耗尽而无效。由此可见，电子定位设备的待机时间，对电子定位设备的适用范围有着很大的影响。

图1为本申请的电子定位设备的功耗控制方法实施例1的流程图。如图1所示，该方法可以包括：
步骤101：获取用于感应物体运动状态的物理量的传感器的感应数据；
所述传感器可以是加速度传感器、陀螺仪或磁力计等等。本步骤的执行主体可以是控制器，例如蓝牙控制器(Bluetooth Controller，BC)。蓝牙控制器的工作电流通常为几十微安，相较于定位模块几个毫安的工作电流，功耗很低。
本申请中的控制器，也可以是微控制单元(Micro Controller Unit，MCU)，或者片上***(System on Chip，SoC)，或者高级RIS微处理器(Advanced RIS Microprocessor，ARM)。
步骤102：根据所述感应数据，判断当前条件是否满足预设触发条件，得到第一判断结果；
所述预设触发条件与所述感应数据之间具有对应关系。当所述感应数 据为加速度数据时，所述预设触发条件可以是与电子定位设备的加速度相关的条件；当所述感应数据为角速度时，所述预设触发条件可以是与电子定位设备的角速度相关的条件。
步骤103：当所述第一判断结果表示当前条件满足所述预设触发条件时，发送第一控制指令；所述第一控制指令用于启动所述电子定位设备中的定位模块，使所述定位模块处于开启状态；
本申请中的电子定位设备中，所述定位模块的开关状态受控制器的控制。例如，控制器与所述定位模块之间可以设置有开关，或者具有开关功能的模块。或者，所述定位模块自身包含具有开关功能的使能端，所述控制器的控制端与所述使能端相连。所述第一控制指令可以对应发送至所述开关，或者发送至所述具有开关功能的模块，或者发送至所述使能端。
步骤104：当所述第一判断结果表示当前条件不满足所述预设触发条件时，保持所述定位模块处于关闭状态。
当前条件不满足所述预设触发条件时，如果所述定位模块原本处于关闭状态，则可以不再执行对于所述定位模块的触发操作。
本实施例中，通过获取用于感应物体运动状态的物理量的传感器的感应数据；根据所述感应数据，判断当前条件是否满足预设触发条件，当前条件满足所述预设触发条件时，发送第一控制指令；所述第一控制指令用于启动所述电子定位设备中的定位模块，使所述定位模块处于开启状态；当所述第一判断结果表示当前条件不满足所述预设触发条件时，保持所述定位模块处于关闭状态；本申请的电子定位设备的功耗控制方法及***，可以在不满足预设触发条件时，始终保持所述定位模块处于关闭状态，当满足预设触发条件后，才启动所述电子定位设备中的定位模块，因此可以大幅提高电子定位设备的待机时间。
图2为本申请的电子定位设备的功耗控制方法实施例2的流程图。如图2所示，该方法可以包括：
步骤201：设定计时器的计数值为初始值；
所述计数值可以为整数。所述初始值可以设定为0，也可以设置为其它整数。
步骤202：蓝牙控制器获取加速度传感器感应得到的加速度数据；
所述蓝牙控制器，也可以是其它功耗较低且具有控制功能的芯片。所述加速度传感器可以长时间处于工作状态，实时感应电子定位设备的加速度信息，生成加速度数据。
步骤203：根据所述加速度数据判断所述电子定位设备是否处于静止状态；如果是，执行步骤204；否则，返回执行步骤201；
当所述加速度数据的数值为零时，可以判定所述电子定位设备处于静止状态。需要说明的是，实际应用中，传感器可能存在微小的误差，因此，在根据所述加速度数据判断所述电子定位设备是否处于静止状态时，对于加速度数据的数值的判断标准，允许存在所述微小的误差。例如，可以将判断标准设定为±0.01m/s 2，当加速度数据的数值在判断标准范围内时，均可以判定所述电子定位设备处于静止状态。还需要说明的是，本说明书中，所有涉及到数值比较的判断步骤中，均允许所述微小误差的存在，在后面的实施例中，不再赘述。
步骤204：对所述计数值加一，得到更新后的计数值；
步骤205：判断所述更新后的计数值是否等于设定数值；如果是，执行步骤206；否则，返回执行步骤202；
所述设定数值可以根据时间长度进行设定。假设将步骤202-205执行一遍的所需时间为1秒，并且需要在静止1分钟后触发定位模块，则该设定数值可以设置为60。
步骤206：向所述电子定位设备中的定位模块发送所述第一控制指令。
本实施例中，可以在电子定位设备处于静止状态的时长达到预设时长时，才触发定位模块进行定位，从而降低电子定位设备的功耗。例如，具体的应用场景可以是，用户将携带有电子定位设备的钱包放置在某处后，该电子定位设备处于静止状态，达到预设时长20分钟后，触发定位模块。上述场景中，可以在用户的钱包等物品脱离用户随身携带范围，且放置时间较长时，对物品进行定位。这种定位方式的效率较高。如果采用实时定位的方式，则用户随身携带该物品时，由于物品一直跟随用户运动，位置 不断更新，将不断触发定位操作，造成较高功耗；另一方面，当物品处于静止状态时进行定位得到的位置信息，更有利于用户根据定位信息寻找该物品。
图3为本申请的电子定位设备的功耗控制方法实施例3的流程图。如图3所示，该方法可以包括：
步骤301：设定计时器的计数值为初始值；
步骤302：蓝牙控制器获取加速度传感器感应得到的加速度数据；
步骤303：根据所述加速度数据判断所述电子定位设备是否处于静止状态；如果是，执行步骤304；否则，返回执行步骤301；

步骤306：监测加速度传感器下一时刻感应得到的加速度数据。
步骤307：根据监测得到的加速度数据判断所述电子定位设备是否处于运动状态；如果是，执行步骤308；否则，返回执行步骤306。
当所述加速度数据的数值不为零时，可以判定所述电子定位设备处于运动状态。需要说明的是，实际应用中，传感器可能存在微小的误差，因此，在根据所述加速度数据判断所述电子定位设备是否处于运动状态时，对于加速度数据的数值的判断标准，允许存在微小的误差。例如，可以将判断标准设定为±0.01m/s 2之间，当加速度数据的数值不在判断标准范围内时，均可以判定所述电子定位设备处于运动状态。
步骤308：向所述电子定位设备中的定位模块发送所述第一控制指令。
本实施例中，可以在电子定位设备处于静止状态的时长达到预设时长后，将电子定位设备设置为运动监测状态；当监测到电子定位设备由静止状态转变为运动状态时，才触发定位模块进行定位，从而降低电子定位设备的功耗。例如，具体的应用场景可以是，用户将电子定位设备放置在保险柜中后，该电子定位设备处于静止状态，达到预设时长20分钟后，进 入运动监测状态，当有人移动保险柜时，触发电子定位设备进行定位。上述场景中，可以实现对特定物品的运动状态的监测，后续当监测到电子定位设备由静止变为运动状态时，所述电子定位设备还可以发出告警信号，从而实现防盗功能。所述告警信号可以发送至与所述电子定位设备具有通信连接的服务器或终端。
图4为本申请的电子定位设备的功耗控制方法实施例4的流程图。如图4所示，该方法可以包括：
步骤401：蓝牙控制器获取加速度传感器感应得到的加速度数据a；
步骤402：判断a是否为非零值；如果是，执行步骤403；否则，返回执行步骤401；
本步骤中，a为非零值时，判定所述电子定位设备处于运动状态。
步骤403：在后续加速度传感器感应得到的加速度数据为非零值时，记录每次获得的加速度传感器感应得到的加速度数据，直至记录得到N个加速度数据；
N的取值可以根据需求进行设置。例如，假设步骤403中，记录一个加速度数据所需的时间为0.5秒，那么如果需要分析电子定位设备在3秒内的运动状态，则可以将N的数值设置为6。
步骤404：根据所述N个加速度数据，判断所述电子定位设备的加速度是否处于线性变化状态；如果是，执行步骤405；否则，返回执行步骤401；
所述电子定位设备的加速度处于线性变化状态，至少包括：连续的相同时间间隔的加速度数据构成等差数列。例如，第一秒，加速度为1，第二秒加速度为2，第三秒加速度为3；或者，第一秒，加速度为1，第二秒加速度为1，第三秒加速度为1。
具体的，可以在获取到加速度传感器感应到的N个加速度数据后，计算相邻的每两个加速度数值之间的差值，如果各个相邻的两个加速度数值之间的差值相等，或者各个相邻的两个加速度数值之间的差值的偏差在预设范围内，则可以判定所述电子定位设备的加速度处于线性变化状态。
步骤405：向所述电子定位设备中的定位模块发送所述第一控制指令。
本实施例中，可以对电子定位设备是否加速度为非零值且处于线性变化状态的时长大于或等于预设时长进行判断，当得到肯定的判断结果时，再触发定位模块进行定位，从而降低电子定位设备的功耗。
图5为本申请的电子定位设备的功耗控制方法实施例5的流程图。如图5所示，该方法可以包括：
步骤501：蓝牙控制器获取加速度传感器感应得到的加速度数据a；
步骤502：判断a是否为非零值；如果是，执行步骤503；否则，返回执行步骤501；
本步骤中，a为非零值时，判定所述电子定位设备处于运动状态。
步骤503：设定计时器的计数值N＝1；
步骤504：在后续加速度传感器感应得到的加速度数据为非零值时，在每次获得加速度传感器感应得到的新的加速度数据时，实时判断所述电子定位设备的加速度是否处于线性变化状态；如果是，执行步骤505；否则，返回执行步骤501；
具体的，可以在每次获取到加速度传感器感应到的加速度数据时，计算最新得到的加速度数值与最近一次得到的加速度数值的第一差值，计算最近一次得到的加速度数值与倒数第二次得到的加速度数值的第二差值，比较所述第一差值与所述第二差值，如果所述第一差值与所述第二差值相等，或者所述第一差值与所述第二差值的偏差在预设范围内，则可以判定所述电子定位设备的加速度处于线性变化状态。
步骤505：对所述计数值加一，得到更新后的计数值；
步骤506：判断所述更新后的计数值是否等于设定数值；如果是，执行步骤507；否则，返回执行步骤504；
当所述更新后的计数值等于设定数值，可以判定所述电子定位设备的加速度处于线性变化的状态的时长达到预设时间长度。
步骤507：向所述电子定位设备中的定位模块发送所述第一控制指 令。
本实施例与实施例4相比，对于电子定位设备是否加速度为非零值且处于线性变化状态的时长大于或等于预设时长的判断方式是不同的。在本实施例中，假设获得加速度传感器感应得到的一个新的加速度数据并且判断所述新的加速度数据与之前获取的加速度之间是否为线性关系，所需的时间为0.5秒，那么如果获取到的第4个加速度数据，不再满足线性关系，则在第2秒就可以返回步骤501，而不再执行步骤505及506。而在实施例4中，在同样的假设条件下，如果需要分析电子定位设备在3秒内的运动状态，则需要将N的数值设置为6，即必须在获取到连续的六个加速度数据并且判断该六个加速度数据是否满足线性关系以后，才能够确定是否触发定位。由于在相同的条件下，实施例4比本实施例执行的步骤多，并且多的步骤中包括数据的计算步骤，因此，本实施例相较于实施例4，功耗更低。
图6为本申请的电子定位设备的功耗控制方法实施例6的流程图。如图6所示，该方法可以包括：
步骤601：设定计时器的计数值为初始值；
步骤602：蓝牙控制器获取加速度传感器感应得到的加速度数据；
步骤603：根据所述加速度数据判断所述电子定位设备是否处于运动状态；如果是，执行步骤604；否则，返回执行步骤601；
步骤604：对所述计数值加一，得到更新后的计数值；
步骤605：判断所述更新后的计数值是否等于设定数值；如果是，执行步骤606；否则，返回执行步骤602；
步骤606：确定所述电子定位设备的所述运动状态的结束时刻。
可以将所述电子定位设备的加速度恢复为零的时刻，确定为所述电子定位设备的运动状态的结束时刻。
步骤607：判断所述电子定位设备从所述结束时刻开始处于静止状态的时长是否大于或等于预设时长；如果是，执行步骤608；否则，返回执行步骤601。
所述预设时长可以根据需求进行设置。例如，可以设置为5分钟，10分钟，或者20分钟等等。
步骤608：向所述电子定位设备中的定位模块发送所述第一控制指令。
本实施例中，可以在电子定位设备的运动状态超过第一预设时长，由运动状态转换为静止状态，并且处于静止状态的时长超过第二预设时长时，触发定位操作。例如，当用户携带电子定位设备进行跑步锻炼时，由于用户长时间处于运动状态，位置一直再变化，因此在用户处于运动状态时对用户进行定位的意义不大。而采用本实施例的方法，可以在用户的运动状态告一段落，处于静止状态时，触发定位，得到的定位信息具有较大的实用价值。
图7为本申请的电子定位设备的功耗控制方法实施例7的流程图。如图7所示，该方法可以包括：
步骤701：设定计数器的计数值为初始值；
步骤702：获取加速度传感器感应得到的加速度脉冲；
所述加速度脉冲可以是计步脉冲，即人行走时加速度传感器感应生成的脉冲。通常情况下，用户每走一步，生成一个脉冲。
步骤703：对所述计数值加一，得到更新后的计数值；
理想情况下，用户行走N步，计数值为N。
步骤704：判断所述更新后的计数值是否达到预设阈值；如果是，执行步骤705；否则，返回执行步骤702；
这里的预设阈值可以根据实际需求进行设置。可以根据用户的步幅长度与移动距离之间的关系，确定预设阈值的具体数值。例如，假设用户的步幅为0.5米，定位的需求是每当电子定位设备移动距离达到100米进行一次定位，则可以将预设阈值设置为200。
步骤705：向所述电子定位设备中的定位模块发送所述第一控制指令。
本实施例中，向所述电子定位设备中的定位模块发送所述第一控制指 令后，还可以重置计数器的计数值为初始值。
本实施例中，通过对加速度传感器感应生成的脉冲信号进行计数，判断计数数值是否达到预设阈值，可以根据用户的步数推算得到电子定位设备的运动距离，从而在电子定位设备的移动距离达到预设阈值时，触发定位操作，从而降低电子定位设备的功耗。
图8为本申请的电子定位设备的功耗控制方法实施例8的流程图。如图8所示，该方法可以包括：
步骤801：设定计时器的计数值为初始值；
步骤802：蓝牙控制器获取加速度传感器感应得到的加速度数据；
步骤803：根据所述加速度数据，判断所述电子定位设备是否完成了一次加速过程以及一次对应的减速过程，得到第三判断结果；如果是，执行步骤804；否则，返回执行步骤802；
判断所述电子定位设备是否完成了一次加速过程以及一次对应的减速过程，具体可以是判断所述电子定位设备是否完成了一次匀加速过程以及一次对应的匀减速过程。例如，所述电子定位设备放置在汽车内，汽车在具有红绿灯的十字路口起步，行驶到下一个十字路口由于红灯停车；这个过程中，汽车起步的过程包括一次匀加速过程，停车的过程包括一次匀减速过程，且该匀加速过程与该匀减速过程具有对应关系。更进一步的，为了便于识别出在路口起步的车辆的加速过程，可以将加速过程设置一个时长条件，比如3至4秒。与此相似，对于减速过程也可以设置3至4秒的时长条件。
步骤804：对所述计数值加一，得到更新后的计数值；
步骤805：判断所述更新后的计数值是否等于设定数值；如果是，执行步骤806；否则，返回执行步骤802；
步骤806：向所述电子定位设备中的定位模块发送所述第一控制指令。
本实施例中，向所述电子定位设备中的定位模块发送所述第一控制指令后，还可以重置计数器的计数值为初始值。
本实施例中，可以对于城市道路中的机动车辆中的电子定位设备进行控制。例如，当设定数值为4时，如果更新后的计数值等于设定数值，则通常表示机动车辆已经行驶通过了四个十字路口，意味着机动车辆的行驶距离已经较长，此时可以触发定位操作，从而降低电子定位设备的功耗。
需要说明的是，本说明书各个实施例中，在所述发送第一控制指令的步骤之后，还可以包括以下步骤：
步骤1：获取所述定位模块输出的位置信息；
步骤2：判断所述位置信息与所述定位模块上一次输出的位置信息之间的位置偏移量是否大于或等于预设位置偏移量，得到第四判断结果；
步骤3：当所述第四判断结果表示所述位置偏移量大于或等于预设位置偏移量时，发送第二控制指令；所述第二控制指令用于启动所述电子定位设备中的定位数据发送模块，使所述定位数据发送模块处于开启状态；
步骤4：当所述第四判断结果表示所述位置偏移量小于预设位置偏移量时，保持所述定位数据发送模块处于关闭状态。
其中，步骤2中，判断所述位置信息与所述定位模块上一次输出的位置信息之间的位置偏移量是否大于或等于预设位置偏移量的具体方式可以有多种。例如，可以采用全球定位***(Global Positioning System，GPS)作为定位模块，每次定位得到电子定位设备的位置坐标。根据当前得到的位置坐标以及最近一次得到的位置坐标，可以计算得到两个位置坐标之间的距离作为位置偏移量。又例如，可以采用Wi-Fi模块作为定位模块。具体的，可以定时扫描电子定位设备周围环境中的wifi网络，获得包含一个或多个可连接的wifi网络的wifi列表；根据wifi列表，确定当前环境中wifi数量的变化率；判断所述变化率是否大于设定阈值，如果大于，则可以判定所述位置信息与所述定位模块上一次输出的位置信息之间的位置偏移量大于或等于预设位置偏移量。
上述步骤中，电子定位设备中的定位数据发送模块可以是具有wifi信号收发功能的模块，也可以是对于符合移动通讯技术标准的信号具有收发能力的模块。所述定位数据发送模块在未接收到第二控制指令之前，通常处于关闭状态。所述定位数据发送模块在接收到第二控制指令之后，才 处于开启状态。在所述定位数据发送模块将当前的位置信息发送出去以后，所述定位数据发送模块可以再次处于关闭状态。采用上述步骤，可以降低定位数据发送模块的功耗，从而进一步降低电子定位设备的功耗。
需要说明的是，本说明书各个实施例中，在所述发送第一控制指令的步骤之前，还可以包括以下步骤：
步骤A：获取与所述电子定位设备保持蓝牙连接的***设备信息；
例如，所述电子定位设备与某一智能手机保持蓝牙连接，则所述***设备包括该智能手机。
步骤B：根据所述***连接设备信息，判断所述电子定位设备是否与具有定位模块的目标***设备通过蓝牙相连，得到判断结果；
假设所述电子定位设备同时与多个***设备通过蓝牙相连，则可以确定一个具有定位模块的***设备作为目标***设备。例如，具有GPS定位模块的智能手机就可以被确定为目标***设备。
步骤C：当所述判断结果表示所述电子定位设备与具有定位模块的目标***设备通过蓝牙相连时，向所述目标***设备发送定位请求，且不再执行所述发送第一控制指令的步骤；所述定位请求用于请求所述目标***设备采用所述目标***设备中的定位模块进行定位；
步骤D：当所述判断结果表示所述电子定位设备未与具有定位模块的目标***设备通过蓝牙相连时，执行所述发送第一控制指令的步骤。
上述步骤中，当电子定位设备与具有定位模块的目标***设备通过蓝牙相连时，可以令目标***设备执行定位操作，并将定位信息作为所述电子定位设备的位置信息，从而进一步节省电子定位设备的功耗。此外，由于蓝牙连接的有效距离范围通常是10米以内，所以目标***设备与电子定位设备的距离通常也不会超过10米，即，将目标***设备的定位信息作为所述电子定位设备的位置信息的位置偏差是可以被接受的。
