在本实施例中，上述mesh指的是“无线网格网络”，是一种多跳网络，各个节点彼此互联。上述mesh音频系统指的是，由多个mesh音箱和云控制终端通过无线网格网络连接组成的音箱系统，每一个mesh音箱都是一个节点，即每个节点都与多个节点相连，无线信号通过各个节点传输；多个mesh音箱在系统中可以是mesh音箱1、mesh音箱2…mesh音箱n。这种网络的好处是即使系统中的某个节点上的音箱损坏，整个网络仍然能够正常运行。上述mesh音箱指的是，具有无线接收和无线发射功能的音箱。上述云控制终端指的是mesh音频系统的服务器，该服务器可以是电脑或者其它智能设备。上述客户端指的是具有无线连接功能并且能够与任意的mesh音箱建立无线连接的移动终端，该移动终端与mesh音箱连接后，可以对mesh音箱发出控制命令。
在一实施例中，mesh音箱还可以包括太阳能单元；太阳能单元包括蓄电池，蓄电池为mesh音箱提供供电。
在本实施例中，由于音箱的耗电量一般都不大，一般音箱的功率都比较低，例如，每个音箱的功率采用20W。因此，可以采用太阳能单元为mesh音箱提供供电是可行的方案。同时，每个mesh音箱设计了射频网络单元，用以满足云端通信，因此，通过太阳能单元提供供电，射频网络单元提供信号传输，本实施 例中提出的mesh音频系统能够在完全不需要布线的情况下，实现整个mesh音频系统的布置，尤其适合公园及景点等需要简化布线的环境。例如，在公园的某处山上，可以设置若干个mesh音箱，满足公园对音箱布局的要求，同时解决了山上布线因难的问题。可选的，在布线方便的情况下，上述mesh音频系统仍然可以采用有线连接方式。可选的，在完成布线的情况下，上述射频网络单元结合有线连接，能够实现同时兼容有线和无线网络连接。
在一个实施例中，每一个mesh音箱还可以包括摄像单元，摄像单元将采集到的影像信息通过无线网络传输至云控制终端。
在本实施例中，上述mesh音频系统尤其适合市政领域使用，并且还配备有网络配合使用，因此在每一个mesh音箱上或者mesh音箱附近设置摄像头，通过mesh音频系统的无线/有线网络直接传输至云控制终端，完成监控布置。本发明提出的mesh音频系统能和监控完美结合，无论是采用有线或者是无线的形式，都能形成摄像头监控系统，比起单独布置摄像头监控系统，节约了成本。例如，在一公园中安装有mesh音频系统，同时，mesh音频系统上的每一个音箱上还设置有摄像头，摄像头通过mesh音频系统的无线网络将所捕捉的影像数据传输至云控制终端。可选的，摄像单元在工作时，其采集帧率超高，耗电量越高，因此，为了节约其耗电量，可将平时摄像单元的采集帧率设置为一个较低值，如每秒20帧；而在特殊的情况下(例如紧急寻找某人、车辆等)，如某个或某些mesh音箱所处地方需要特别细致的监控时，则可将摄像单元的采集帧率变更为一个较高的值，如每秒60帧。可选的，上述帧率变更可以是由云控制终端控制，也可以设置紧急物理按钮mesh音箱上，由路人按动紧急按钮控制，同时，按钮可配合报警装置使用。
在一个实施例中，每一个mesh音箱还包括检测单元，检测单元用于检测mesh音箱各单元是否正常工作。
在本实施例中，上述检测单元指的是可以对mesh音箱中的控制单元、射频网络单元以及太阳能单元进行检测的自检单元，当检测到某一单元工作不正常时，可以通过无线网络将异常信息(异常信息可以是检测日志检测异常代号等)发送云控制终端，工作人员通过查看云控制终端的异常信息，获知mesh音箱的异常情况，进一步对异常的mesh音箱进行维护。本实施例中，通过设置检测单元，达到检修维护的作用，省去了定期使用人力检查mesh系统的成本。
在一个实施例中，系统建立无线连接完成后，每一个mesh音箱均通过射频 网络单元发射wifi信号。
在本实施例中，mesh音频系统所有节点均建立起连接关系后，形成一个由云控制终端至节点的网格网络。在本实施例中，使各个节点均能发射wifi信号，无需增加网络装置。实际应用中只需要mesh音箱中的射频网络单元支持wifi发射，即可使每一个mesh音箱所在的安装位置变成一个wifi发射点。例如，在一个公园中，安装有30个mesh音箱，每一个mesh音箱均支持wifi发射，系统启动后，该公园增加了由mesh音箱发出的30个wifi发射点，wifi信号覆盖率大大增加，增强了公园内游客的娱乐体验。
本发明提出的mesh音频系统，系统包括：云控制终端以及多个mesh音箱；每一个mesh音箱均设有控制单元、射频网络单元；控制单元用于控制mesh音箱的音频播放；mesh音箱通过射频网络单元接收或发射无线信号，进行无线连接；至少两个mesh音箱与云控制终端无线连接，且系统中每一个mesh音箱至少能识别到其它两个mesh音箱发出的无线信号并与所识别到的mesh音箱建立无线连接；每一个mesh音箱还连接一个或多个用户端，用户端用以控制单个mesh音箱。本发明通过太阳能电源供电为音频系统供电，无线网络传输方式，达到简化布线，增强了音频系统的适用性，增强了产品竞争力。
参照图3，本申请实施例中同时提出一种mesh音频系统管理方法，方法包括：
S10、mesh音箱接收云控制终端发出的启动信号，并启动；
S20、mesh音箱接收云控制终端发出的控制命令；
S30、根据控制命令进入对应的控制状态；其中控制状态包括第一控制状态以及第二控制状态；第一控制状态下mesh音箱执行云控制终端的命令以及用户端的命令，并优先执行用户端的命令；第二控制状态下mesh音箱只执行云控制终端的命令；
S40、若mesh音箱接收到用户端发出的用户指令，判断mesh音箱是否处于第二控制状态下；若mesh音箱处于第二控制状态下，则继续执行第二控制状态下云控制终端发出的指令；若mesh音箱不处于第二控制状态下，则执行用户指令。
如上述步骤S10，上述云控制终端所发出的启动信号，该启动信号将会使整个mesh音频系统中的所有mesh音箱全部启动。特别的，由于mesh音频系统中所有的mesh音箱都有编号，因此也可以针对对应的mesh音箱进行启动。例如， 云控制终端发出启动信号，只启动mesh音箱1、mesh音箱2，其他的mesh音箱则不启动。
如上述步骤S20，上述所有mesh音箱启动后，进入第一控制状态指的是mesh音箱接受云控制终端的统一控制，云控制终端发出统一针对所有mesh音箱的命令，各个mesh音箱统一执行。需要强调的是，处于第一控制状态的mesh音箱，在接收到用户的控制指令时，可以终止第一控制状态，即不接受云控制终端针对第一控制状态下mesh音箱的统一命令。进一步地，上述第一控制状态也可以认为是一种连接关系，mesh音箱无线连接云控制终端，作为云控制终端的外放，接收云控制终端的音频信号，然后播放接收到的音频信号。例如把云控制终端看作电脑主机，mesh音箱则是连接该主机的音响。
如上述步骤S30，上述特权指令指的是云控制终端发出的一种特殊的指令，在发出该指令之后，所有接到该指令的mesh音箱，均受到云控制终端的控制且只受到云控制终端的控制，这种最高权限的控制适合运用在紧急情况进行紧急情况的公众广播。例如一公园中装有mesh音频系统，由于天气突变，即将有冰雹及暴雨来临，工作人员通过云控制终端控制指定(部分或全部)的mesh音箱(即使部分mesh音箱由用户个性化控制)，云控制终端拿到所有mesh音箱的控制权，然后发出紧急广播，告知公园内游客天气情况，以使大家及时躲避。第二控制状态只能由云控制终端解除。
如上述步骤S40，上述若任意mesh音箱接收到用户端发出的用户指令，判断mesh音箱是否处于第二控制状态下；指的是，用户通过用户端发出对mesh音箱的控制命令，则mesh音箱需先检测是否处于第二控制状态下，若是，则忽略用户端的命令，若不是，则接受用户端的命令，使用户得以自行操控音箱。特别的，与常规音箱系统不同的是，本实施例中的所有音箱都可能被用户自行操控，即每一个mesh音箱都在不同的位置，可以让不同位置的多个用户同时实现个性化操控。
在一个实施例中，mesh音箱接收云控制终端发出的启动信号，并启动的步骤，还包括：
mesh音箱启动自检程序进行自检，若自检出mesh音箱工作异常，则向云控制终端发送mesh音箱异常信息。
在本实施例中，上述自检程序指的是可以对mesh音箱中的控制单元、射频网络单元以及太阳能单元进行检测的程序，当检测到某一单元工作不正常时， 可以通过无线网络将异常信息(异常信息可以是检测日志检测异常代号等)发送云控制终端，工作人员通过查看云控制终端的异常信息，获知mesh音箱的异常情况，进一步对异常的mesh音箱进行维护。本实施例中，通过设置检测单元以及自检程序，达到检修维护的作用，省去了定期使用人力检查mesh系统的成本。
在一实施例中，mesh音箱接收云控制终端发出的启动信号，并启动的步骤之前，还包括：
mesh音箱检测其它mesh音箱或云控制中心发出的无线信号，并与所检测到的mesh音箱以及云控制中心建立无线连接。
在本实施例中，mesh音频系统是一种网格状态网络，各个mesh音箱都会检测其他mesh音箱的无线信号，并与检测到的mesh音箱进行无线连接，由此形成网格状态网络，其优点是即使网络中有一两个节点损坏，也不会对整个系统的工作造成严重影响，除了损坏的节点之外，其它节点仍然能正常工作。
在一个实施例中，mesh音箱接收云控制终端发出的启动信号，并启动的步骤之后，还包括：
检测当前可连接的其它mesh音箱的第一数量，并判断第一数量是否与预设一致；
若不一致，则判定mesh音箱为连接点异常，将连接点异常的mesh音箱编号发送云控制终端；以通过云控制终端获取所有连接点异常的mesh音箱在正常连接时所检测到的预设mesh音箱的编号；计算预设mesh音箱的编号的交集，得出网络异常的mesh音箱的编号；
通过算法(a.b...n)∩...∩(s.p...q)＝y，得出具体网络异常mesh音箱的编号y；其中括号中的编号为检测到连接点异常的mesh音箱在正常连接时所检测到的mesh音箱的编号。
在本实施例中，除了自检程序能够对mesh音箱自身进行检测之外，在mesh音频系统中，各个mesh音箱还能进行互检，由于mesh音频系统在布置完成之后，mesh音频系统中节点的数量以及各节点的位置都是确定的，假如某个节点上的音箱检测到当前可连接的mesh音箱的数量与预设数量不一致，则说明可能有音箱损坏了，例如可能损坏的音箱为x，找到所有与x具有连接关系的mesh音箱；并通过算法(a.b...n)∩...∩(s.p...q)＝y进一步确定，上述算法中单个括号中的编号为同一mesh音箱在正常时所检测到的mesh音箱的编号。求出交集， 若交集为y＝x则说明所得到的交集即为确定损坏的节点，若交集
Figure PCTCN2020098924-appb-000001
则说明x未损坏，系统检测出错或x的信号强度低。例如，图4中包含数字1的最小闭合区域代表mesh音箱1，同理可得mesh音箱2至mesh音箱7在图4中所属区域，其中上述最小闭合区域与其它区域的公共边代表mesh音箱的网络连接关系。具体的，对于mesh音箱5，与区域5具有公共边的区域为2，4，6；即mesh音箱2，4，6与mesh音箱5具有连接关系。若mesh音箱5损坏，原来能检测到mesh音箱5的网络而现在检测不到了，这些检测当前可连接mesh音箱数量与预设数量不一致的音箱分别为mesh音箱2、mesh音箱4、mesh音箱6；
mesh音箱2在正常时检测到的音箱为mesh音箱1、mesh音箱3、mesh音箱5；
mesh音箱4在正常时检测到的音箱为mesh音箱1、mesh音箱5、mesh音箱7；
mesh音箱6在正常时检测到的音箱为mesh音箱3、mesh音箱5、mesh音箱7；
则(1.3.5)∩(1.5.7)∩(3.5.7)＝5，即音箱5损坏。
可选的，当mesh音箱y未能与云控制中心建立网络通讯；同时，有两个以上的正常情况下能与mesh音箱y建立网络连接，但在上报云控制中心均未检测到mesh音箱y，则判断mesh音箱y损坏。
本申请同时提出一种计算机存储介质，其上存储有计算机程序，计算机程序被处理器执行时实现上述方法中中任一项所述的方法的步骤。
本领域普通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完成，所述的程序可以存储于一种计算机可读存储介质中，上述提到的存储介质可以是只读存储器，磁盘或光盘等。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
