下面对本申请实施例进行详细介绍。
请参阅图1，所示为本申请的一实施例中的蓝牙连接控制方法的步骤流程图。该蓝牙连接控制方法包括如下步骤：
步骤100，控制子路由单元中的一个子路由模块与主路由模块之间的连接间隔模式为快速连接间隔模式。
请一并参阅图2，所示为本申请的第一实施例中的蓝牙连接控制系统的示意图。
蓝牙连接控制系统90可包括路由器50及一个或多个从设备，如包括从设备602、从设备604及从设备606。从设备可包括蓝牙芯片，以通过蓝牙网络与路由器50进行通信。路由器50可将从设备传输的数据转换为其他类型的数据(如Wi-Fi类型的数据)，以使得从设备可通过路由器50接入到其他网络或通过路由器50将数据存储于远端的服务器内。本实施例中，从设备内的蓝牙芯片可工作于从模式下，其中，工作于从模式下的从设备可进行蓝牙广播，以等待工作于主模式下的蓝牙设备扫描。从设备602、从设备604及从设备606可为手写本。当手写本未检测到触发操作时，手写本内的蓝牙芯片可工作于休眠状态；当检测到触发操作时，如用户使用手写笔在手写本上绘制图形或文字等，手写本内的蓝牙芯片可从休眠状态进入唤醒状态，并执行蓝牙广播操作，以等待被主模式下的蓝牙设备扫描。
本实施例中，路由器50包括主路由模块510及子路由单元520，子路由单元520包括若干子路由模块，每一子路由模块可为工作于主模式下的蓝牙芯片，其中，工作于主模式下的蓝牙芯片或设备可扫描周围广播的蓝牙设备，以与广播的蓝牙设备连接或通信。本实施例中，子路由单元520可包括子路由模块522、子路由模块524及子路由模块526。
主路由模块510用于控制每一子路由模块和主路由模块510之间的连接间隔模式。本实施例中，主路由模块510与子路由模块之间的连接间隔模式包括快速连接间隔模式及慢速连接间隔模式，其中，连接间隔表示主路由模块与子路由模块进行数据交换时相邻两个连接事件之间的时间间隔，连接间隔可以1.25微秒为单位，连接间隔的值可为6(7.5ms)～3200(4s)。快速连接间隔模式 可表示子路由模块以较快的传输速度(如连接间隔的值为6)与主路由模块通信，慢速连接间隔模式可表示子路由模块以较慢的传输速度(如连接间隔的值为1000)与主路由模块通信。
当路由器50上电时，主路由模块510可发送慢速连接参数指令至子路由单元520中的每一子路由模块，以使得每一子路由模块的连接间隔模式均处于慢速连接间隔模式下。在路由器50上电的预设时间后，主路由模块510发送快速连接参数指令至子路由单元520中的一个子路由模块，以使得接收到快速连接参数指令的子路由模块改变其连接间隔模式，并同时执行扫描操作，以接入唤醒状态下从设备发送的蓝牙广播。
例如，上电时，主路由模块510可将慢速连接参数指令发送至子路由模块522、子路由模块524及子路由模块526，子路由模块522、子路由模块524及子路由模块526接收到连接参数指令后，分别控制其与主路由模块510之间的连接间隔模式均为慢速连接间隔模式。主路由模块510可存储子路由模块522、子路由模块524、子路由模块526的参数信息，如带宽、功耗等参数信息，主路由模块510可选择各子路由模块中具有最小带宽或最小功耗的子路由模块传输快速连接参数指令。在上电1秒后，主路由模块510可将快速参数指令发送到最小带宽或最小功耗的子路由模块，如子路由模块522。当接收到快速参数指令时，子路由模块522可改变与主路由模块510之间的连接间隔模式，如由慢速连接间隔模式转换为快速连接间隔模式，子路由模块522同时执行扫描操作。子路由模块522执行扫描操作时，可获取唤醒后从设备的发送蓝牙广播，子路由模块522可对蓝牙广播进行解析，以得到发送蓝牙广播的从设备的服务UUID(Universally Unique Identifier，通用唯一识别码)或MAC地址(Media Access Control Address，媒体访问控制地址)等标识信息。
在一实施例中，主路由模块510内还存储有对应从设备的服务UUID或MAC地址等标识信息。因此，当子路由模块从蓝牙广播解析得到从设备(如从设备602)所对应标识信息后，可获取主路由模块510内存储的标识信息，并将解析得到的标识信息与主路由模块510存储的标识信息进行匹配。当主路由模块510存储的标识信息内包含解析得到的标识信息时，表示已识别了该从设备，此时，子路由模块可接入该从设备(如从设备602)，以接收从设备发 送的数据。当主路由模块510存储的标识信息内没有包含解析得到的标识信息时，子路由模块可不接入该从设备，或是执行子路由模块与从设备之间的配对操作，并在配对成功后由子路由模块接入该从设备。
在其他实施例中，当路由器50上电时，主路由模块510可从子路由单元520中随机选择一个子路由模块接收快速连接参数指令，以便利随机选择的子路由模块在接收快速连接参数指令改变自身与主路由模块的连接间隔模式。
在一实施例中，在路由器50上电时，主路由模块510可直接发送快速连接参数指令至子路由单元520中的一个子路由模块，并发送慢速连接参数指令至其他的子路由模块。如在路由器50上电时，主路由模块510可发送快速连接参数指令至子路由模块522，以使得子路由模块522处于快速连接间隔模式，还同时发送慢速连接参数指令至子路由模块524及子路由模块526，以使得子路由模块524及子路由模块526等没有接入从设备的子路由模块处于慢速连接间隔模式。此时，路由器50中只有子路由模块522同时处于快速连接间隔模式及执行扫描操作的子路由模块，而子路由模块524及子路由模块526则处于慢速连接间隔模式，也没有执行扫描操作。
请一并参阅图3，所示为本申请的第二实施例中的蓝牙连接控制系统的示意图。
与第一实施例相比，本实施例中，子路由单元520可包括依次物理连接的子路由模块522、子路由模块524及子路由模块526，其中，子路由模块522位于第一连接位置，子路由模块524连接于子路由模块522并位于第二连接位置，子路由模块526连接于子路由模块524并位于第三连接位置。
当路由器50上电时，子路由单元520内的各子路由模块均可处于休眠状态；在路由器50上电的预设时间后，主路由模块510可发送快速连接参数指令至位于第一连接位置的子路由模块522，以控制位于第一连接位置的子路由模块522处于快速连接间隔模式，子路由模块522接收到快速连接参数指令后，控制其与主路由模块510之间的连接间隔模式，并执行扫描操作，以接入唤醒状态下的从设备发送的蓝牙广播。此时，路由器50中只有子路由模块522同时处于快速连接间隔模式及执行扫描操作的子路由模块，而子路由模块524及子路由模块526则处于休眠状态，也没有执行扫描操作。
步骤102，判断接入到所述子路由模块的从设备的接入数量是否达到预设数量；若是，执行步骤104；若否，执行步骤106。
每一子路由模块可接入对应的预设数量的从设备，其中，预设数量与子路由模块所支持的带宽最大值相关。例如，当接入的从设备所占用的带宽达到子路由模块所支持的带宽的最大值时，可确定子路由模块接入的从设备已达到预设数量。
步骤104，控制所述子路由模块停止执行扫描操作，并控制子路由单元中没有接入从设备的一个子路由模块执行扫描操作。
为减少路由器50工作时的功耗，路由器50控制子路由单元520中只有一个子路由模块同时处于快速连接间隔模式及执行扫描操作，并控制没有接入从设备的子路由模块处于慢连接间隔模式或是控制没有接入从设备的子路由模块处于休眠状态。
在一实施例中，当子路由模块接入的从设备的接入数量达到预设数量时，主路由模块510可控制没有接入从设备的子路由模块执行扫描操作。
例如，子路由模块522同时处于快速连接间隔模式及执行扫描操作，在子路由模块522接入从设备的接入数量达到预设数量时，子路由模块522停止扫描操作，并发送传输上限指令至主路由模块510。主路由模块510可选择没有接入从设备的子路由模块，如子路由模块524。此时，主路由模块510可发送快速连接参数指令至子路由模块524。子路由模块524接收到快速连接参数指令后，改变与主路由模块510之间的连接间隔模式，如由慢速连接间隔模式转换为快速连接间隔模式。子路由模块524在接收到快速连接参数指令的同时执行扫描操作，以将唤醒状态下的从设备接入到子路由模块524内。此时，路由器50内包括子路由模块522及子路由模块524两个处于快速连接间隔模式的子路由模块，而只有子路由模块524一个子路由模块执行扫描操作，没有接入从设备的子路由模块526则处于慢连接间隔模式。
在一时间内，从设备可能会断开与路由器50之间的连接，如子路由模块522中存在一些已断开连接的从设备，此时，子路由模块522的接入数量没有达到预设数量。若子路由模块524接入从设备的接入数量达到预设数量，此时，主路由模块510可接收到子路由模块524传输的上限指令。由于处于快速连接 间隔模式下的子路由模块522接入数量没有达到预设数量，因此，主路由模块510可控制没有达到预设数量的子路由模块522继续执行扫描操作，以接入唤醒状态下的从设备至子路由模块522上，有利于提高资源的利用率，可减少控制处于慢速连接间隔模式的子路由模块执行扫描操作而带来的资源的浪费的不足。
在一实施例中，当子路由模块接入的从设备的接入数量达到预设数量时，主路由模块510可控制处于休眠状态的子路由模块执行扫描操作。
例如，子路由模块522同时处于快速连接间隔模式及执行扫描操作，在子路由模块522接入从设备的接入数量达到预设数量时，由于子路由模块522处于第一连接位置，子路由模块522停止扫描操作，并发送传唤醒指令至位于子路由模块522的下一连接位置的子路由模块，如子路由模块524。此时，子路由模块524由休眠状态进行唤醒状态，并改变与主路由模块510之间的连接间隔模式为快速连接间隔模式，还同时执行扫描操作，以将唤醒状态下的从设备接入到子路由模块524内。
在其他实施方式中，当处于第一位置的子路由模块522的接入数量达到预设数量时，子路由模块522亦可停止扫描操作，并发送传输上限指令至主路由模块510。主路由模块510可选择位于第二位置的子路由模块执行扫描操作，如子路由模块524。此时，主路由模块510可发送唤醒指令至子路由模块524。子路由模块524接收到唤醒指令后，子路由模块524由休眠状态进行唤醒状态，并改变与主路由模块510之间的连接间隔模式为快速连接间隔模式，还同时执行扫描操作，以将唤醒状态下的从设备接入到子路由模块524内。此时，路由器50内包括子路由模块522及子路由模块524两个处于快速连接间隔模式的子路由模块，而只有子路由模块524一个子路由模块执行扫描操作，子路由模块526仍处于休眠状态。
步骤106，控制所述子路由模块继续执行扫描操作。
当子路由模块522接入从设备的接入数量没有达到预设数量时，表示子路由模块522还可接入从设备，因此，为减少资源的浪费及功耗的损失，主路由模块510可控制子路由模块522继续执行操作，以接入唤醒后的从设备。
上述蓝牙连接控制方法在确定子路由模块的接入数量达到预设数量后选择 控制未接入从设备的子路由模块接入或是控制已接入从设备的子路由模块中没有达到预设数量的子路由模块接入，以控制子路由单元中只有一个同时处于快速连接间隔模式及执行扫描状态的子路由模块，有利于有利于提高资源的利用率，降低系统功耗。

所述存储装置502可用于存储所述计算机程序和/或模块，所述处理器500通过运行或执行存储在所述存储装置502内的计算机程序和/或模块，以及调用存储在存储装置502内的数据，实现上述蓝牙连接控制方法的各种功能。所述存储装置502可主要包括存储程序区和存储数据区，其中，存储程序区可存储操作系统、至少一个功能所需的应用程序等。此外，存储装置502可以包括高速随机存取存储装置，还可以包括非易失性存储装置，例如硬盘、内存、插接式硬盘，智能存储卡(Smart Media Card，SMC)，安全数字(Secure Digital，SD)卡，闪存卡(Flash Card)、至少一个磁盘存储装置件、闪存器件、或其他易失性固态存储装置件。
所述处理器500通过读取存储装置502中存储的可执行程序代码来运行与所述可执行程序代码对应的程序，以用于执行前面任一实施例中路由器所执行的蓝牙连接控制方法的步骤。
示例性的，所述计算机程序可以被分割成一个或多个模块/单元，所述一个或者多个模块/单元被存储在所述存储装置502中，并由所述处理器500执行，以完成本申请。所述一个或多个模块/单元可以是能够完成特定功能的一系列计算机程序指令段，该指令段用于描述所述计算机程序在所述路由器50中的执行过程。
本实施例中，子路由单元520包括若干子路由模块，每一子路由模块可工作于主模式下的蓝牙芯片。例如，本实施例中，子路由单元520可包括第一子路由模块、第二子路由模块及第三子路由模块。
处理器500用于通过主路由模块510控制每一子路由模块所主路由模块510之间的连接间隔模式。本实施例中，主路由模块510与子路由模块之间的连接间隔模式包括快速连接间隔模式及慢速连接间隔模式。
在一实施例中，当路由器50上电时，处理器500可控制主路由模块510发送慢速连接参数指令至子路由单元520中的每一子路由模块，以使得每一子路由模块的连接间隔模式均处于慢速连接间隔模式下。在路由器50上电的预设时间后，处理器500控制主路由模块510发送快速连接参数指令至子路由单元520中的一个子路由模块，以使得接收到快速连接参数指令的子路由模块改变其连接间隔模式，并同时执行扫描操作，以接入唤醒状态下从设备发送的蓝牙广播。
例如，上电时，处理器500控制主路由模块510将慢速连接参数指令发送至第一子路由模块、第二子路由模块及第三子路由模块，第一子路由模块、第二子路由模块及第三子路由模块接收到连接参数指令后，控制其与主路由模块510之间的连接间隔模式均为慢速连接间隔模式。存储装置502可存储第一子路由模块、第二子路由模块、第三子路由模块的参数信息，如带宽、功耗等参数信息，处理器500可选择各子路由模块中具有最小带宽或最小功耗的子路由模块，并控制主路由模块510传输快速连接参数指令至最小带宽或最小功耗的子路由模块。在上电预设时间(如1秒)后，主路由模块510可将快速参数指 令发送到最小带宽或最小功耗的子路由模块，如第一子路由模块。当接收到快速参数指令时，第一子路由模块可改变与主路由模块510之间的连接间隔模式，如由慢速连接间隔模式转换为快速连接间隔模式，第一子路由模块同时执行扫描操作。第一子路由模块执行扫描操作时，可获取唤醒后从设备的发送蓝牙广播，第一子路由模块可对蓝牙广播进行解析，以得到发送蓝牙广播的从设备的服务UUID(Universally Unique Identifier，通用唯一识别码)或MAC地址(Media Access Control Address，媒体访问控制地址)等标识信息。
在一实施例中，存储装置502内还存储有从设备的服务UUID或MAC地址等标识信息。因此，当子路由模块从蓝牙广播解析得到从设备所对应标识信息后，可将获取存储装置502内存储的标识信息，并将解析得到的标识信息与存储装置502存储的标识信息进行匹配操作，当存储装置502存储的标识信息内包含解析得到的标识信息时，表示已识别了该从设备，此时，子路由模块可接入该从设备，以接收从设备发送的数据。
在一实施例中，当路由器50上电时，处理器500可控制主路由模块510从子路由单元520中随机选择一个子路由模块接收快速连接参数指令。
在一实施例中，在路由器50上电时，处理器500可控制主路由模块510直接发送快速连接参数指令至控制子路由单元520中的一个子路由模块，并发送慢速连接参数指令至其他的子路由模块。如在路由器50上电时，处理器500可控制主路由模块510发送快速连接参数指令至第一子路由模块，以使得第一子路由模块处于快速连接间隔模式，还同时发送慢速连接参数指令至第二子路由模块及第三子路由模块，以使得第二子路由模块及第三子路由模块等没有接入从设备的子路由模块处于慢速连接间隔模式。此时，路由器50中只有第一子路由模块同时处于快速连接间隔模式及执行扫描操作的子路由模块，而第二子路由模块及第三子路由模块则处于慢速连接间隔模式，也没有执行扫描操作。
当子路由模块接入的从设备的接入数量达到预设数量时，处理器500可控制主路由模块510选择没有接入从设备的子路由模块执行扫描操作。
例如，第一子路由模块同时处于快速连接间隔模式及执行扫描操作，在第一子路由模块接入从设备的接入数量达到预设数量时，第一子路由模块停止扫 描操作，并发送传输上限指令至处理器500。处理器500可控制主路由模块510选择没有接入从设备的子路由模块，如第二子路由模块。此时，处理器500可控制主路由模块510发送快速连接参数指令至第二子路由模块。第二子路由模块接收到快速连接参数指令后，改变与主路由模块510之间的连接间隔模式，如由慢速连接间隔模式转换为快速连接间隔模式。第二子路由模块在接收到快速连接参数指令的同时执行扫描操作，以将唤醒状态下的从设备接入到第二子路由模块内。此时，路由器50内包括第一子路由模块及第二子路由模块两个处于快速连接间隔模式的子路由模块，而只有第二子路由模块一个子路由模块执行扫描操作，没有接入从设备的第三子路由模块则处于慢连接间隔模式。
在一时间内，从设备可能会断开与路由器50之间的连接，如第一子路由模块中存在一些已断开连接的从设备，此时，第一子路由模块的接入数量没有达到预设数量。若第二子路由模块接入从设备的接入数量达到预设数量，此时，处理器500可接收到第二子路由模块传输的上限指令。由于处于快速连接间隔模式下的第一子路由模块接入数量没有达到预设数量，因此，处理器500可控制主路由模块510选择没有达到预设数量的第一子路由模块继续执行扫描操作，以接入唤醒状态下的从设备至第一子路由模块上，如此，有利于提高资源的利用率。
在一实施例中，子路由单元520可包括依次物理连接的第一子路由模块、第二子路由模块及第三子路由模块，其中，第一子路由模块位于第一连接位置，第二子路由模块位于第二连接位置，第三子路由模块位于第三连接位置。
当路由器50上电时，子路由单元520内的各子路由模块均可处于休眠状态；在路由器50上电的预设时间后，处理器500可控制主路由模块510发送快速连接参数指令位于第一连接位置的子路由模块，以控制位于第一连接位置的第一子路由模块处于快速连接间隔模式，第一子路由模块接收到快速连接参数指令后，控制其与主路由模块510之间的连接间隔模式，并执行扫描操作，以接入唤醒状态下的从设备发送的蓝牙广播。此时，路由器50中只有第一子路由模块同时处于快速连接间隔模式及执行扫描操作的子路由模块，而第二子路由模块及第三子路由模块则处于慢速连接间隔模式，也没有执行扫描操作。
当子路由模块接入的从设备的接入数量达到预设数量时，主路由模块510 可控制处于休眠状态的子路由模块执行扫描操作。
例如，第一子路由模块同时处于快速连接间隔模式及执行扫描操作，在第一子路由模块接入从设备的接入数量达到预设数量时，由于第一子路由模块处于第一连接位置，第一子路由模块停止扫描操作，并发送传唤醒指令至位于第一子路由模块的下一连接位置的子路由模块，如第二子路由模块。此时，第二子路由模块由休眠状态进行唤醒状态，并改变与主路由模块510之间的连接间隔模式为快速连接间隔模式，还同时执行扫描操作，以将唤醒状态下的从设备接入到第二子路由模块内。
当第一子路由模块接入从设备的接入数量没有达到预设数量时，表示第一子路由模块还可接入从设备，因此，为减少资源的浪费及功耗的损失，处理器500可控制主路由模块510选择第一子路由模块继续执行操作，以接入唤醒后的从设备。
上述路由器在确定子路由模块的接入数量达到预设数量后选择控制未接入从设备的子路由模块接入或是控制已接入从设备的子路由模块中没有达到预设数量的子路由模块接入，以控制子路由单元中只有一个同时处于快速连接间隔模式及执行扫描状态的子路由模块，有利于提高资源的利用率，降低系统功耗。另外，上述路由器可在确定子路由模块的接入数量没有达到预设数量控制处于快速连接间隔模式的子路由模块继续执行扫描操作，有利于提高资源的利用率，降低系统功耗。
