Description

电子设备以及电子设备的控制方法 技术领域
本申请涉及低功耗技术领域，尤其涉及一种电子设备以及电子设备的控制方法。
背景技术
低功耗蓝牙(BLE4.0及以上的版本)因其功耗极低的特点(一般一节纽扣电池可供其连续工作一至数年)，成为了主流的针对低成本低功耗需求的无线方案，广泛应用于医疗、家居、娱乐等领域。
现有低功耗蓝牙系统一般包括低功耗蓝牙主设备，以及各种形式的低功耗蓝牙从设备，低功耗蓝牙从设备体积小并不会配置大容量的供电电池，当个别低功耗蓝牙从设备电池耗尽时，由于部署的蓝牙设备较多不会影响系统正常运行，但是当一定数量的蓝牙设备宕机后，整个低功耗蓝牙系统将会瘫痪甚至崩溃。
例如，一个低功耗蓝牙系统可能需要1个低功耗蓝牙主设备和4个低功耗蓝牙从设备同时工作才能维持其高精度的工作，假如现在系统中有8个低功耗蓝牙从设备，起初当低功耗蓝牙从设备逐个宕机时，整个网络不会有影响。当正常工作的低功耗蓝牙从设备数降到4个时，如果此时再有低功耗蓝牙从设备宕机，整个系统可能工作不正常。
发明人在实现本申请的过程中发现，现有技术至少存在以下问题：低功耗蓝牙主设备不能掌握整个系统中各低功耗蓝牙从设备的情况，导致在系统中 低功耗蓝牙从设备数目到达临界时，无法进行相应的措施以确保整个系统持久稳定有效的工作。

具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请部分实施例进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
本申请的第一实施例涉及一种电子设备，例如为低功耗蓝牙从设备，用于与低功耗蓝牙主设备连接，例如为手机、平板电脑等，低功耗蓝牙从设备与低功耗蓝牙主设备组成低功耗蓝牙系统。如图1所示，电子设备包括第一数据选择器1、多个高功耗器件、低功耗定时器2以及模式控制器3；多个高功耗器件中包括微控制器4。
第一数据选择器1的第一输出端连接于微控制器4的输入端，第二输出端连接于低功耗定时器2的输入端，选通控制端连接于模式控制器3；低功耗计时器2连接于多个高功耗器件中的若干个高功耗器件。
模式控制器3用于在检测到低功耗切换命令时，控制第一数据选择器1选通第二输出端，第一数据选择器1的第二端连接于低功耗定时器2，此时，低功耗定时器2被启动，低功耗定时器2用于关闭多个高功耗器件并开始计时；低功耗定时器2还用于在计时至预设周期时，唤醒若干个高功耗器件，以发送预设信号，低功耗定时器2在预设信号发送完毕后，控制关闭若干个高功耗器件并重新开始计时。
本实施例中，在电子设备只需传递少量的信息，并且对传递信息的频率要求很低时，可以判定为检测到所述低功耗切换命令，低功耗定时器2被启动，低功耗定时器2关闭多个高功耗器件并开始计时，直至计时至预设周期时，唤醒若干个高功耗器件，以发送预设信号，预设信号可以为用户自定义的较短的数据。
本实施例中，高功耗器件是指单位时间内消耗电量较高的器件，多个高功耗器件是指电子设备中用于供电子设备正常工作的所有高功耗器件，若干个高功耗器件包括用于发送预设信号所必需的全部高功耗器件。
本实施例相对于现有技术而言，提供了一种电子设备，可以在检测到低功耗切换命令时，关闭多个高功耗器件，以降低功耗，延长从设备的存活时间。
本申请的第二实施例涉及一种电子设备，本实施例是对第一实施例的细化，主要细化之处在于：本实施例中，模式控制器3为电量检测器件。
本实施例中，当电量检测器件检测到所述电子设备处于低电量状态时，判定为检测到所述低功耗切换命令，低功耗定时器2被启动，低功耗定时器2关闭多个高功耗器件并开始计时，直至计时至预设周期时，唤醒若干个高功耗器件，以发送预设信号，预设信号为表征低电量的警示信号。
其中，低电量状态可以是指电量小于一个预设的电量下限值而无法正常工作，设备将在很短时间内电量耗尽而宕机。
于实际中，请参考图2，电子设备还包括预设信号发送器5与低频时钟发生器6，若干个高功耗器件中包括高频时钟发生器7。
高频时钟发生器7与低频时钟发生器6分别连接于第一数据选择器1的输入端；预设信号发送器5与低功耗定时器2一同连接于第一数据选择器1的第二输出端，预设信号发送器5还连接于低功耗定时器2。
本实施例中，当未检测到低功耗切换命令(电子设备处于正常电量状态)时，第一数据选择器1选通第一输出端，高频时钟发生器7输出高频时钟信号至微控制器4，低频时钟发生器6输出低频时钟信号至微控制器4，此时电子设备处于正常工作状态。
本实施例中，当检测到低功耗切换命令(电子设备处于低电量状态)时，第一数据选择器1选通第二输出端，高频时钟发生器7输出高频时钟信号至预设信号发送器5，低频时钟发生器6输出低频时钟信号至低功耗定时器2，低功 耗定时器2控制关闭包括微控制器4在内的多个高功耗器件并开始计时，此时电子设备进入超低功耗的工作模式。预设信号发送器5用于在高频时钟信号的时序控制下发送预设信号，并在预设信号发送完毕后通知低功耗定时器2，低功耗定时器2重新计时，计时至预设周期时，预设信号发送器5再次发送预设信号。本实施例中，增设了一个专用于发送预设信号的预设信号发送器，以减少高功耗器件的开启，进一步降低了功耗。
本实施例中，预设信号发送器5可以是专用的beacons发送控制器，发送的预设信号可以是一个极短的beacons数据包。电子设备正常工作时，预设信号发送器5完全处于关闭状态。当电子设备处于低电量状态时，预设信号发送器定时被唤醒发送预设信号。
其中，预设信号是一个极短的beacons数据包，其包含：低功耗蓝牙协议规定的广播信道Preamble(形式50105010b)，低功耗蓝牙协议规定的Access Address(形式0x8E89BED6)，发送信道可根据低功耗蓝牙协议规定的广播信道ch37、ch38、ch39中任意选择发送，但不限于此。
一个例子，请参考图2，电子设备还包括第二数据选择器8；第二数据选择器9的第一输入端连接于微控制器4的输出端，第二输入端连接于预设信号发送器10的输出端，选通控制端连接于模式控制器3；其中，模式控制器3在检测到低功耗切换命令时，控制第二数据选择器8选通第二输入端。本实施例第二数据选择器与第一数据选择器同步切换，即当检测到低功耗切换命令时，第二数据选择器只允许预设信号发送器输出预设信号，从而可以避免预设信号受到微控制器4的干扰，确保了信号的稳定。
于实际中，请参考图2，若干个高功耗器件还包括电源切换控制器9； 电源切换控制器9用于在其被唤醒时，将电子设备由辅助电源切换至主电源供电；在被关闭时，将电子设备由主电源切换至辅助电源供电。在确保预设信号正常发送的基础上，尽可能降低功耗。
例如，请参考图2，电子设备为低功耗蓝牙设备时，若干个高功耗器件还包括发射天线10，用于将预设信号无线发射出去。
实际上，本实施例提供了一种电子设备超低功耗的工作模式，电子设备可以是一种低功耗蓝牙从设备，具体如下：
1、模式控制器3检测到低功耗蓝牙从设备自身电量过低而无法进行正常工作或只需发送少量数据信息时，控制第一数据选择器1选通第二输出端，此时微控制器4被关闭(微控制器4也属于电子设备内的一种高功耗器件)。
2、低功耗定时器2被启动，关闭电子设备内部的多个高功耗器件并开始计时。其中，多个高功耗器件包括电源切换控制器9，电源切换控制器9控制低功耗蓝牙从设备由主电源切换至辅助电源供电。此时，仅保留低功耗定时器2工作。低功耗定时器2关闭的内部高功耗器件例如包括高频时钟发生器7，电源切换控制器9、发射天线10。
3、当低功耗定时器2计时到达预定周期时，唤醒若干个高功耗器件。其中，若干个高功耗器件包括电源切换控制器9，电源切换控制器9控制低功耗蓝牙从设备由辅助电源切换至主电源供电。此时，预设信号发送器5控制发送预设信号beacons数据包，一般通过发射天线10将预设信号无线发射出去。
例如，低功耗定时器2唤醒的若干个高功耗器件包括高频时钟发生器7，发射天线10。
4、发送完毕，低功耗定时器2控制关闭若干个高功耗器件并重新开始 计时，仅保留低功耗定时器2。
5、重复上述步骤3～4，不断地发出预设信号。
于实际中，在低功耗蓝牙主设备端，由于beacons数据包的发送方式、发送频率与现有低功耗蓝牙设备兼容，因此不需要添加其它额外硬件，即可完成对beacons数据包的解析，并根据接收端RSSI(接收信号强度指示)，计算获得该低功耗蓝牙主设备的位置。根据当前整个系统中各从设备情况，提示用户进行管理。
本实施例相对于第一实施例而言，在电子设备处于低电量状态时，发送表征低电量的警示信号，使主设备能及时发现以便于进行相应的处理，从而保持了系统的稳定性。
本申请的第三实施例涉及一种电子设备，本申请第三实施例是对第二实施例的细化，主要细化之处在于：对预设信号发送器5进行了具体的介绍。
本实施例中，请参考图3，预设信号发送器5包括两个序列产生器501与射频控制器502；序列产生器501与射频控制502分别连接于第一数据选择器1的第二输出端，序列产生器501还连接于射频控制502；序列产生器501用于产生预设信号，射频控制器502用于控制预设信号发送出去。两个序列产生器501产生序列预设信号并发送到buffer缓冲器，通过buffer缓冲器生成预设信号数据，预设信号数据经过射频控制器502发送，发送完成后，射频控制器502通知低功耗定时器2关闭若干个高功耗器件并开始计时，同时关闭射频控制器502。
需要说明的是，本实施例是以两个序列产生器501为例，实际中，可以对序列产生器501是否运行进行预先配置，从而控制选择一个或者两个序列产 生器501运行，若只有一个序列产生器501运行，同样可以完成预设信号的发送，然不限于此。
于实际中，还可以仅设置一个序列产生器501，此时序列产生器501产生的预设信号可以不通过buffer缓冲器生成预设信号数据，直接将产生的预设信号发送到射频控制器502，即，序列产生器501可以直接连接射频控制器502，发送预设信号。
本实施例相对于第二实施例而言，提供了一种预设信号发送器的具体实现方式，满足了实际设计需求。
本申请的第四实施例涉及一种电子设备，本申请第四实施例与第二实施例大致相同，主要区别之处在于：本实施例中，提供了一种不增加其他元器件便能够发送预设信号的方案。
本实施例中，请参考图4，若干个高功耗器件中包括高频时钟发生器7与微控制器4；电子设备还包括低频时钟发生器6。高频时钟发生器7与低频时钟发生器6分别连接于第一数据选择器1的输入端。
本实施例中，当未检测到低功耗切换命令时，第一数据选择器1选通第一输出端，高频时钟发生器7输出高频时钟信号至微控制器4，低频时钟控制器6输出低频时钟信号至微控制器4，此时电子设备处于正常工作状态。
本实施例中，当检测到低功耗切换命令时，第一数据选择器1选通第二输出端时，高频时钟发生器7输出高频时钟信号至微控制器4，低频时钟发生器6输出低频时钟信号至低功耗定时器2，低功耗定时器2控制关闭多个高功耗器件并开始计时，此时电子设备进入超低功耗的工作模式。微控制器4在高频时钟信号的时序控制下发送预设信号，并在预设信号发送完毕后通知低功耗 定时器2，低功耗定时器2重新计时，计时至预设周期时，微控制器4再次发送预设信号。
本实施例相对于第二实施例而言，提供了一种不增加其他元器件便能够发送预设信号的方案，可以通过微控制器发送预设信号，便于根据实际情况灵活选择，同时节约了一定的成本。
本申请第五实施例涉及一种电子设备的控制方法，电子设备包括第一数据选择器、低功耗定时器、预设信号发送器、模式控制器与多个高功耗器件，多个高功耗器件包括若干个高功耗器件，若干个高功耗器件中包括高频时钟发生器。电子设备的控制方法的具体流程图如图5所示。
步骤101，判断是否检测到低功耗切换命令。若是，则进入步骤102；若否，则直接结束。
具体而言，当电子设备只需传递少量的信息，并且对传递信息的频率要求很低时，可以判定为检测为到所述低功耗切换命令，或者模式控制器为电量检测器件，当电量检测器件检测到所述电子设备处于低电量状态时，判定为检测到所述低功耗切换命令。
步骤102，启动低功耗定时器。
具体而言，当判定检测到所述低功耗切换命令时，此时接收到一个启动指令，启动低功耗定时器。
步骤103，低功耗定时器关闭多个高功耗器件并开始计时。
具体而言，启动低功耗定时器后，电子设备结束正常工作状态，进入超低功耗的工作模式，低功耗定时器控制关闭多个高功率器件降低功耗，以使电子设备维持的时间更长，随后低功耗定时器开始计时。
步骤104，判断是否计时至预设周期。
具体而言，对是否计时至预设周期进行判断，若是，则进入步骤105，唤醒多个高功耗器件；若否，则继续进行判断，直至到达预设周期。
需要说明的是，预设周期应该要比电子设备正常的广播周期要长很多，以兼顾低功耗以及告知其他设备的功能，一般为秒级。
步骤105，低功耗定时器唤醒多个高功耗器件中的若干个高功耗器件，以发送预设信号。
具体而言，当电子设备只需传递少量的信息，并且对传递信息的频率要求很低时，在低功耗定时器在计时至预定周期时，预设信号发送器发送预设信号(预设信号可以为用户自定义的较短的数据)。而当模式控制器3为电量检测器件，电量检测器件检测到电子设备处于低电量状态时，为了使自身能及时被主设备发现以便于处理，从设备(电子设备)需要定时通知主设备，从而保持了系统的稳定性；即低功耗定时器在计时至预定周期时，预设信号发送器会发送预设信号，预设信号为表征低电量的警示信号。预设信号的发送需要若干个高功耗器件的支持。因此，低功耗定时器需要唤醒若干个高功耗器件。
于实际中，请参考图6，步骤105，低功耗定时器唤醒多个高功耗器件中的若干个高功耗器件，以发送预设信号，具体包括：
子步骤1051，低功耗定时器唤醒若干个高功耗器件后，高频时钟发生器输出高频时钟信号至预设信号发送器。
具体而言，预设信号发送器需要高频时钟信号的时序控制才能发出预设信号，因此，若干个高功耗器件中至少包括高频时钟发生器；唤醒高频时钟发生器，高频时钟发生器输出高频时钟信号到预设信号发送器。
子步骤1052，预设信号发送器在高频时钟信号的时序控制下发送预设信号。
具体而言，预设信号发送器接收到高频时钟信号时，生成并发送预设信号。
子步骤1053，预设信号发送器在预设信号发送完毕后通知低功耗定时器。
具体而言，预设信号发送器在预设信号发送完毕后，会产生一个表征发送完毕的信号至低功耗定时器；低功耗定时器收到该信号时，关闭该若干个高功耗器件。
一个例子，预设信号可以为蓝牙信号。预设信号的长度小于低功耗蓝牙协议中设定的广播信号长度，且预设周期大于低功耗蓝牙协议中设定的广播间隔。本实施例中，设置专有形式的预设信号，以尽可能降低功耗，保证设备能够维持更长时间的现有工作状态，同时降低了预设信号与其他设备之间直接的相互干扰。
其中，预设信号发送的信道需要在低功耗蓝牙协议规定的广播信道中，使其更加容易地被扫描发现。
步骤106，低功耗定时器关若干个高功耗器件，并重新开始计时。
具体而言，发送完预设信号后，电子设备再次进入超低功耗模式，关闭若干个高功耗器件，并重新开始计时，进入步骤104，判断计时是否至预设周期，在计时至预设周期时，再次发送预设信号。
需要说明的是，本实施例中，启动低功耗定时器，低功耗定时器控制关闭多个高功耗器件，在低功耗定时器计时至预设周期时，才通过预设信号发送 器发送预设信号，然实际中不限于此。
不难发现，本实施例为与第一实施例、第二实施例相对应的方法实施例，本实施例可与第一实施例、第二实施例互相配合实施。第一实施例、第二实施例中提到的相关技术细节在本实施例中依然有效，为了减少重复，这里不再赘述。相应地，本实施例中提到的相关技术细节也可应用在第一实施例、第二实施例中。
本实施例相对于现有技术而言，可以在检测到电子设备处于低电量状态时，关闭多个高功耗器件，以降低功耗，延长从设备的存活时间，同时按预定周期发出低电量警示信号，使主设备能及时发现以便于进行相应的处理，从而保持了系统的稳定性。
本申请第六实施例涉及一种电子设备的控制方法，本实施例是对第五实施例的改进，主要改进之处在于：在检测到低功耗切换命令时，立即发送一个预设信号。
本实施例的电子设备的控制方法具体流程如图7所示。
其中，步骤201、步骤202与步骤101、步骤102对应大致相同，步骤205至步骤208与步骤103至步骤106对应大致相同，在此处不再赘述；不同之处在于，本实施例中，增加了步骤203和步骤204，具体解释如下：
步骤203，预设信号发送器在高频时钟信号的时序控制下发送预设信号。
具体而言，当检测到低功耗切换命令时，高频时钟发生器输出高频时钟信号到预设信号发送器，预设信号发送器在高频时钟信号的控制下，发送预设信号。
步骤204，预设信号发送器在预设信号发送完毕后通知低功耗定时器。
具体而言，预设信号发送器在预设信号发送完毕后，需要通知低功耗定时器，以使其能够及时的关闭若干个高功耗器件。低功耗定时器被启动，关闭若干个高功耗器件，随后开始计时，电子设备进入超低功耗的工作模式。
本实施例相对于第四实施例而言，在启动低功耗定时器之后，且在低功耗定时器关闭多个高功耗器件并开始计时之前，发送了一次发送预设，能够更及时的通知主设备。
本申请第七实施例涉及一种电子设备的控制方法，本实施例与第五实施例大致相同，主要区别之处在于：本实施例中，提供了一种不增加其他元器件便能够发送预设信号的方案。
本实施例中，若干个高功耗器件中包括高频时钟发生器与微控制器。电子设备的控制方法的具体流程如图8所示。其中，步骤301至步骤304与步骤101、步骤104对应大致相同，步骤306与步骤106对应大致相同，在此处不再赘述；不同之处在于：
本实施例中，步骤305，低功耗定时器唤醒多个高功耗器件中的若干个高功耗器件，以发送预设信号，具体包括：
子步骤3051，低功耗定时器唤醒若干个高功耗器件后，高频时钟发生器输出高频时钟信号至微控制器。
具体而言，若干个高功耗器件包括微控制器，微控制器需要高频时钟信号来控制发出预设信号，此时，唤醒高频时钟发生器，高频时钟发生器输出高频时钟信号到微控制器。
子步骤3052，微控制器在高频时钟信号的时序控制下发送预设信号。
具体而言，高频时钟发生器输出高频时钟信号到微控制器，微控制器 在高频时钟信号的控制下，发送预设信号。
子步骤3053，微控制器在预设信号发送完毕后通知低功耗定时器。
具体而言，微控制器在预设信号发送完毕后，需要通知低功耗定时器，以使其能够及时的关闭若干个高功耗器件。
值得一提的是，本实施例中，低功耗定时器被启动，关闭内部多个高功耗器件，低功耗定时器计时至预设周期时，微控制器被控制发出预设信号；于实际中，可以在低功耗定时器被启动时，立刻控制微控制器发出一个预设信号，以更及时的通知主设备。
由于第四实施例与本实施例相互对应，因此本实施例可与第四实施例互相配合实施。第四实施例中提到的相关技术细节在本实施例中依然有效，在第四实施例中所能达到的技术效果在本实施例中也同样可以实现，为了减少重复，这里不再赘述。相应地，本实施例中提到的相关技术细节也可应用在第四实施例中。
本实施例相对于第五实施例而言，提供了一种不增加其他元器件便能够发送预设信号的方案，可以通过微控制器发送预设信号，便于根据实际情况灵活选择，同时节约了一定的硬件成本。
本申请第八实施例涉及一种电子设备的控制方法，本实施例是对第五实施例的改进，主要改进之处在于：增加了对电子设备是否正在连线或者正在广播的判断。
本实施例的电子设备的控制方法具体流程如图9所示。
其中，步骤401与步骤101对应大致相同，步骤404至步骤408与步骤102至步骤106对应大致相同，在此处不再赘述；不同之处在于，本实施例 中，增加了步骤402和步骤403，具体解释如下：
步骤402，检测电子设备是否正在连线或者正在广播。若是，则进入步骤403；若否，则进入步骤404。
具体而言，当检测到低功耗切换命令时，电子设备如果仍正在连线或者广播，则可能影响到预设信号的发送。
步骤403，切断连线或停止广播。
具体而言，当检测到电子设备正在连线或正在广播时，切断连线或停止广播。
需要说明的是，切断连线是指电子设备断开当前与之连接的所有设备。
本实施例相对于第五实施例而言，对电子设备是否正在连线或者正在广播进行判断，便于及时的切断连线或停止广播，以免对接下来预设信号的发送产生影响。
本领域技术人员可以理解实现上述实施例方法中的全部或部分步骤是可以通过程序来指令相关的硬件来完成，该程序存储在一个存储介质中，包括若干指令用以使得一个设备(可以是单片机，芯片等)或处理器(processor)执行本申请各个实施例所述方法的全部或部分步骤。而前述的存储介质包括：U盘、移动硬盘、只读存储器(ROM，Read-Only Memory)、随机存取存储器(RAM，Random Access Memory)、磁碟或者光盘等各种可以存储程序代码的介质。
本领域的普通技术人员可以理解，上述各实施例是实现本申请的具体实施例，而在实际应用中，可以在形式上和细节上对其作各种改变，而不偏离本申请的精神和范围。
