在上述通过智能终端对多台播放设备进行控制的过程中，播放设备与智能终端之间是通过蓝牙技术进行通信的，在通信过程中可能存在以下问题：若系统内播放设备较多且每一台播放设备的蓝牙功能均开启，则智能终端与播放设备的蓝牙配对过程会因为蓝牙设备列表中的可配对设备过多而产生混淆，智能终端无法快速准确地连接到用户指定的播放设备中，从而影响了智能终端对音乐播放系统的控制效率。
发明内容
本发明实施例提供一种多播放设备的蓝牙连接控制方法、装置、音乐播放系统、设备及计算机存储介质，旨在解决在由多播放设备组成的音乐播放系统中，智能终端无法快速准确地连接到用户指定的播放设备中的问题。

第一控制单元，用于若所述播放设备接收到所述响应，控制所述播放设备的蓝牙功能处于关闭状态；
第二控制单元，用于若所述播放设备未接收到所述响应，开启所述播放设备的蓝牙功能，以使智能终端在蓝牙配对过程中搜索到所述播放设备。
本发明实施例的另一目的在于提供一种音乐播放系统，所述系统包括多个播放设备，每个所述播放设备包括如上所述的多播放设备的蓝牙连接控制装置。
本发明实施例的另一目的在于提供一种设备，包括：一个或者多个处理器；存储器；一个或者多个程序，所述一个或者多个程序存储在所述存储器中，当被所述一个或者多个处理器执行时，执行本发明上述实施例的多播放设备的蓝牙连接控制方法。
本发明实施例的另一目的在于提供一种非易失性计算机存储介质，所述计算机存储介质存储有一个或者多个程序，当所述一个或者多个程序被一个设备执行时，使得所述设备执行本发明上述实施例的多播放设备的蓝牙连接控制方法。
本发明实施例可以保证音乐播放系统内始终只有一台播放设备的蓝牙功能处于开启状态，这样一来，智能终端在蓝牙配对过程中，在蓝牙设备列表中都只会看到音乐播放系统内的一台播放设备，方便智能终端快速准确地连接到播放设备之中，提高音乐播放系统的控制效率。
附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。
图1是现有技术提供的音乐播放系统的系统架构图；
图2是本发明实施例提供的多播放设备的蓝牙连接控制方法的实现流程图；
图3是本发明实施例提供的多播放设备的蓝牙连接控制方法S203的具体实现流程图；
图4是本发明实施例提供的多播放设备的蓝牙连接控制装置的结构框图。
具体实施方式
以下描述中，为了说明而不是为了限定，提出了诸如特定系统结构、技术之类的具体细节，以便透切理解本发明实施例。然而，本领域的技术人员应当清楚，在没有这些具体细节的其它实施例中也可以实现本发明。在其它情况中，省略对众所周知的系统、装置、电路以及方法的详细说明，以免不必要的细节妨碍本发明的描述。
为了说明本发明所述的技术方案，以下首先对现有技术中由多台播放设备组成的音乐播放系统进行说明：
图1示出了现有技术提供的音乐播放系统的系统架构，为了便于说明，仅示出了与本实施例相关的部分。
参照图1，该音乐播放系统由多台播放设备构成，这些播放设备分别分布在一定区域范围内的不同位置，并集成了网络通信功能，进一步地，所述网络通信功能为无线网络通信功能，例如，WiFi通信功能。基于所集成的网络通信功能，音乐播放系统内的多台播放设备可以组成一个局域网，以使位于不同区域的播放设备可以连接起来，相互进行通信。
此外，上述播放设备中还配置了蓝牙模块，以使得播放设备可以通过蓝牙与智能手机等智能终端进行配对连接，智能终端通过与音乐播放系统的其中一台播放设备建立连接，并在智能终端中预先安装用于控制该音乐播放系统的控制应用，智能终端就能够通过与其建立连接的播放设备实现对音乐播放系统的访问和播放控制。在智能终端的播放控制之下，音乐播放系统可以与互联网连接，获取互联网音乐资源，具体地，可以利用智能终端的互联网功能，由智能终端从互联网上获取到音乐数据并推送到音乐播放系统播放；或者，音乐播放系统还可以播放本地存储的音乐数据，例如，存储在播放设备内部存储器或外部存储器上的音乐数据，存储在智能终端的音乐数据，以及其他位于同一局域网内可访问的设备(例如NAS服务器)上存储的音乐数据。例如，智能手机与音乐播放系统内的一台播放设备进行蓝牙连接，并通过该播放设备对音乐播放系统进行播放设置，设置音乐播放系统内的三台播放设备同步播放音乐，则当智能手机中的音乐播放器播放歌曲时，其播放的音乐数据通过蓝牙传递到与其建立连接的播放设备中，该播放设备再通过局域网将音乐数据推送到这三台播放设备中，这三台播放设备便会与智能手机同步进行歌曲播放。
上述音乐播放系统可以进一步扩展为，将音乐播放系统中的多个播放设备分为若干个播放组，每个播放组分别播放不同的音乐数据，且各个播放组可以由同一智能终端进行播放控制，也可以分别由不同智能终端进行播放控制。例如，一个音乐播放系统中有A、B、 C、D、E、F这6台播放设备，其中，播放设备A和B组成播放组1，播放设备C和D组成播放组2，播放设备E和F组成播放组3，播放组1中的播放设备A和B同步播放相同的歌曲，播放组2中的播放设备C和D同步播放相同的歌曲，播放组3中的播放设备E和F同步播放相同的歌曲，但上述三个播放组是相互独立的，可以播放相同的歌曲，也可以分别播放不同的歌曲。各个播放组可以接受不同智能终端的控制，也可以接受相同智能终端的控制。
基于上述音乐播放系统的说明，接下来，对本发明实施例提供的多播放设备的蓝牙连接控制方法和装置进行详细阐述。
图2示出了本发明实施例提供的多播放设备的蓝牙连接控制方法的实现流程，该流程的执行主体为音乐播放系统中的播放设备。
在S201中，在播放设备开机后发送广播消息，所述广播消息用于询问与所述播放设备位于同一音乐播放系统内的其他播放设备是否开启了蓝牙功能。
每台播放设备开机后，都会在音乐播放系统的局域内发送广播消息，该广播消息用于询问该音乐播放系统内是否有已经开启了蓝牙功能的其他播放设备。接收到该广播消息且开启了蓝牙功能的播放设备会向发送该广播消息的播放设备返回一条响应，以告知其蓝牙功能处于开启状态。同理地，当该播放设备蓝牙功能开启的状态之下，若收到了来自同一音乐播放系统内其他播放设备的广播消息，则也会向发送广播消息的播放设备返回该响应。
作为本发明的一个实施例，为了使音乐播放系统内的所有播放设备都能够接收到上述广播消息，保证广播通信的可靠性，进一步地，S201可以通过以下方式实现：：
以第一预设时间为间隔，连续发送预设次数的所述广播消息。
例如，以200毫秒为间隔，连续发送三次广播消息，以避免由于网络传输延时或者丢包而造成的广播消息未发送成功所导致的误判。
在S202中，检测是否接收到所述其他播放设备根据所述广播消息返回的响应，所述响应用于表示发送该响应的播放设备已开启了蓝牙功能。
在S203中，若所述播放设备接收到所述响应，控制所述播放设备的蓝牙功能处于关闭状态。
在S204中，若所述播放设备未接收到所述响应，开启所述播放设备的蓝牙功能，以使智能终端在蓝牙配对过程中搜索到所述播放设备。
若播放设备在发出广播消息之后，接收到了来自同一音乐播放系统内的其他播放设备返回的响应，则表明当前在该音乐播放系统内，已经有播放设备开启了蓝牙功能，那么此时，控制本播放设备的蓝牙功能处于关闭状态；若未接收到来自同一音乐播放系统内的其他播放设备返回的响应，则表明当前在该音乐播放系统内还未有播放设备开启了蓝牙功能， 此时，控制本播放设备的蓝牙功能开启。
进一步地，S202中的检测过程可以在播放设备发出广播消息之后的一段预设时间之后进行，以保证返回的响应能够在检测前被顺利接收到，保证了检测结果的准确性。
上述方案可以保证音乐播放系统内始终只有一台播放设备的蓝牙功能处于开启状态，这样一来，智能终端在蓝牙配对过程中，在蓝牙设备列表中都只会看到音乐播放系统内的一台播放设备，方便智能终端快速准确地连接到播放设备之中，提高音乐播放系统的控制效率。
针对上文中所述的音乐播放系统包括多个播放组，每个播放组中包括了一台或多台播放设备的应用场景，如图3所示，S203具体为：
S301，判断所述播放设备与返回所述响应的所述其他播放设备是否属于同一所述播放组。
在每台播放设备中，都会预先设置好其所归属的播放组信息，包括播放组的名称、播放组中的播放设备名称，等等，在播放设备返回的响应中，携带了该播放设备的IP地址、所述的播放组名称或者该播放设备的名称，等等，通过解析响应中携带的信息及本地存储的播放组信息，可以判断出返回响应的播放设备与本播放设备是否属于同一播放组。
S302，若所述播放设备与返回所述响应的所述其他播放设备属于同一所述播放组，控制所述播放设备的蓝牙功能处于关闭状态。
S303，若所述播放设备与返回所述响应的所述其他播放设备不属于同一所述播放组，开启所述播放设备的蓝牙功能，以使智能终端在蓝牙配对过程中搜索到所述播放设备。
若返回响应的播放设备与本播放设备属于同一播放组，则表明当前在该播放组内，已经有播放设备开启了蓝牙功能，那么此时，控制本播放设备的蓝牙功能处于关闭状态；若返回响应的播放设备与本播放设备未属于同一播放组，则表明当前在该播放组内还未有播放设备开启了蓝牙功能，此时，控制本播放设备的蓝牙功能开启。
上述方案可以在多播放组的应用场景下，保证每个播放组中同一时间只有一台播放设备开启蓝牙功能，这样一来，方便智能终端快速准确地连接到相应播放组的播放设备之中，提高音乐播放系统的控制效率。
同时，在多播放组的应用场景之下，当执行的是S303，即本播放设备的开启了蓝牙功能之后，所述方法还包括：
将所述播放设备的蓝牙模块名称设置为所述播放设备归属的所述播放组的名称。
即，本播放设备根据预先存储的播放组归属信息，将其蓝牙模块设置为其所在播放组的名称，或者，若其未分配播放组或者其所在的播放组未被命名，则本播放设备将其蓝牙模块设置为其自己的设备名称。将蓝牙模块名称设置成播放组名称，可以使得智能终端在 进行蓝牙配对时，更加迅速、准确地定位到需要同步播放控制的播放组中，进一步地提高了音乐播放系统的操作效率。
由于在音乐播放系统的工作过程中，各台播放设备是分布在不同位置的，且随着智能终端的移动，与智能终端进行蓝牙连接的播放设备与智能终端的距离可能越来越远，甚至超出了蓝牙的可通信范围，导致传输质量差或者连接不稳定，音乐播放出现卡顿或者中断现象，影响音乐的播放效果，考虑到上述问题，在音乐播放系统的工作过程中提出如下方案：
若所述播放设备的蓝牙功能开启，每隔第二预设时间依次向所述其他播放设备发送蓝牙工作状态信息；
若所述播放设备的蓝牙功能关闭且未接收到来自所述其他播放设备的蓝牙工作状态信息，开启所述播放设备的蓝牙功能。
即，若当前开启蓝牙功能的是本播放设备，则该播放设备每隔第二预设时间依次向与其位于同一音乐播放系统或者同一播放组内的其他播放设备发送其蓝牙工作状态信息，该蓝牙工作状态信息用于表明其蓝牙功能处于正常工作状态，若其蓝牙功能处于关闭状态或者非正常工作状态，则该蓝牙工作状态信息不会被发送。例如，音乐播放系统内的一个播放组由播放设备A、B、C、D组成，播放设备A开启了蓝牙功能，则播放设备A先向播放设备B发送蓝牙工作状态信息，发送结束100毫秒之后，播放设备A再向播放设备C发送蓝牙工作状态信息，发送结束100毫秒之后，播放设备A再向播放设备D发送蓝牙工作状态信息，发送结束100毫秒之后，播放设备A再向播放设备B发送蓝牙工作状态信息……如此循环。根据一个播放组能够容纳的播放设备的最大数量，依次向所有播放设备发送完一遍蓝牙工作状态信息的周期需要满足：周期>＝(第二预设时间间隔*(播放组最大播放设备数－1))，该周期可以根据播放组内实际的播放设备数量进行调整。
而若当前开启蓝牙功能的不是本播放设备，则会监听是否有来自于其所在播放组的其他播放设备发送的蓝牙工作状态信息，若在一定的周期(例如，5个周期)内均没有接收到任何一个播放设备发送的蓝牙工作状态信息，则表明该播放组内原先与智能终端进行连接的播放设备已关机或者网络中断，此时，本播放设备开启蓝牙功能，用于与智能终端保持蓝牙连接，实现智能终端对音乐播放系统的控制。由于蓝牙工作状态信息是每隔一预设时间间隔发送给一台播放设备的，因此，通常会有一台播放设备会最先检测到之前的蓝牙连接已断开的结果，并在下一台播放设备检测出之前的蓝牙连接断开之前及时开启其蓝牙功能，保证与智能终端的蓝牙连接不间断。
进一步地，所述方法还包括：
若所述播放设备接收到关闭指令且所述播放设备的蓝牙功能开启，则指定所述其他播 放设备中的一个开启蓝牙功能。
所述关闭指令，用于指示播放设备待机或者退出播放组甚至音乐播放系统，一旦播放设备在蓝牙功能开启的情况下检测到其接收到了关闭指令，则在执行该关闭指令之前，在其所在播放组内选择(可采用随机选择或者其他选择算法进行选择，在此不作限定)一个播放设备启动蓝牙功能，以保证与智能终端连接的连续性。
应理解，上述实施例中各步骤的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本发明实施例的实施过程构成任何限定。
