本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
参照图1，图1为本发明广播源控制方法第一实施例的流程示意图。
本发明实施例提供了广播源控制方法的实施例，需要说明的是，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。在本实施例中，广播源控制方法应用于广播源设备。在本实施例中，广播源控制方法包括：
步骤S10，基于目标无线通信技术检测所述广播源设备广播范围内的广播接收端信息，其中，所述目标无线通信技术的通信范围覆盖所述广播范围；
广播源设备可以是能够基于广播技术发送广播的设备，本实施例中，广播源设备所采用的广播技术可以是但不限于是LE Audio广播技术。由于广播源设备在发送广播数据时一般不需要与接收端建立通信连接，所以广播源设备无法获知是否有接收端、接收端的能力等情况，进而只能根据固定的广播参数进行广播，而无法根据接收端的具体情况灵活调整广播参数以获得更好的广播效果。
在本实施例针对上述问题提出解决方案。具体地，广播源设备可以基于目标无线通信技术检测广播源设备广播范围内的广播接收端信息。其中，目标无线通信技术是通信范围能够覆盖广播源设备的广播范围的无线通信技术。需要说明的是，目标无线通信技术的通信范围能够覆盖广播范围是指通信距离大于或等于广播距离减去一定的误差，也即，通信距离比广播距离稍小，也可以认为通信范围能够覆盖广播源设备的广播范围。
在具体实施方式中，可以根据广播技术或广播源设备的类型来选取采用哪种无线通信技术来作为目标无线通信技术。例如，当广播源设备采用LE Audio广播技术进行广播时，目标无线通信技术可以采用UWB(Ultra Wide Band，超宽带)技术；UWB技术的通信范围与广播源设备的广播范围相当，且UWB技术具有系统复杂度低，发射信号功率谱密度低，对信道衰落不敏感，截获能力低，定位精度高等优点，尤其适用于室内等密集多径场所的高速无线接入，也即能够适用于LE Audio广播技术的使用场景。
广播源设备中可以设置基于目标无线通信技术的通信模块(例如通信芯片)，通过该通信模块与广播范围内的接收端设备进行通信，进而获取广播接收端信息。在具体实施方式中，广播接收端信息可以包括表征广播范围内是否存在接收端设备的信息，或者可以包括广播范围内存在接收端设备时接收端设备与广播源设备的距离，或者，还可以包括其他信息，在本实施例中并不做限制。
步骤S20，根据所述广播接收端信息设置所述广播源设备的广播参数，并按照所设置的广播参数进行广播。
广播源设备在获取到广播接收端信息后，即可根据广播接收端信息来设置广播源设备 的广播参数，并按照所设置的广播参数进行广播。其中，广播参数可以包括广播重传次数、广播发射功率、广播发送时间间隔、广播内容类型等，在本实施例中并不做限制。
例如，在一实施方式中，当广播接收端信息包括接收端设备的设备类型时，可以根据设备类型来确定广播内容类型。例如，当接收端设备都是带显示屏和喇叭的设备时，可以确定广播内容类型为视频和音频；当接收端设备都是不带显示屏只有喇叭的设备时，可以确定广播内容类型为音频，以避免广播源设备进行无效的视频广播而浪费设备资源。
在具体实施方式中，广播源设备可以是在进行广播前检测广播接收端信息，根据检测到的广播接收端信息设置广播参数后开始进行广播，也可以是在进行广播的过程中定时检测广播接收端信息，在广播过程中灵活调整广播参数。
在本实施例中，通过广播源设备基于通信范围能够覆盖广播范围的目标无线通信技术检测广播范围内的广播接收端信息，根据广播接收端信息设置广播源设备的广播参数，并按照所设置的广播参数进行广播，实现了一种广播源的智能控制方案，能够根据接收端信息来调整广播参数以灵活调整广播效果。
进一步地，在一实施方式中，所述步骤S10包括：
步骤S101，通过目标无线通信技术向外发送通信请求；
当广播接收端信息包括表征广播范围内是否存在接收端设备的信息时，广播源设备可以通过目标无线通信技术向外发送通信请求。具体地，可以通过广播源设备中设置的基于目标无线通信技术的通信模块向外发送通信请求。通信请求中携带的信息可以用于向其他设备表示请求建立通信连接，或请求反馈响应消息，具体携带的信息在本实施方式中并不做限制。
步骤S102，若在发送所述通信请求后预设时长内未接收到针对所述通信请求反馈的响应消息，则确定所述广播范围内不存在接收端设备。
广播源设备可以在向外发送通信请求后开始计时，检测在预设时长内是否接收到针对该通信请求的响应消息。其中，预设时长可以根据需要设置，一般地，预设时长可以设置得大于广播源设备从发送通信请求到接收到通信范围最远处接收端设备反馈的响应消息的时间间隔。
若在预设时长内未接收到针对该通信请求反馈的响应消息，则可以确定广播范围内不存在接收端设备，也即得到表征广播范围内不存在接收端设备的广播接收端信息。
需要说明的是，当广播源设备定时检测广播接收端信息时，可以定时向外发送通信请 求，两次发送通信请求的间隔时长设置得大于预设时长。
在一实施方式中，若在预设时长内接收到针对该通信请求反馈的响应消息，则广播源设备可以确定广播范围内存在接收端设备。
在另一实施方式中，当目标无线通信技术的通信距离大于广播距离时，也可以是在预设时长内接收到针对该通信请求反馈的响应消息时，广播源设备检测发送该响应消息的设备与广播源设备之间的距离是否小于或等于广播距离，若发送响应消息的设备与广播源设备之间的距离都大于广播距离，则可以确定广播范围内不存在接收端设备，若有至少一个发送响应消息的设备与广播源设备之间的距离小于或等于广播距离，则可以确定广播范围内存在接收端设备。
在另一实施方式中，也可以是在预设时长内接收到针对该通信请求反馈的响应消息时，广播源设备进一步确定响应消息中是否携带广播接收码，若至少一个响应消息中携带广播接收码，则可以确定广播范围内存在接收端设备，若响应消息中均没有携带广播接收码，则可以确定广播范围内不存在接收端设备；其中，其他设备在接收到通信请求时，可以在响应消息中携带广播接收码，广播接收码可以是由其他设备的用户在设备中输入的，用于表示该用户有权限收听广播。
进一步地，在另一实施方式中，所述步骤S101之后，还包括：
步骤S103，若在发送所述通信请求后预设时长内接收到所述响应消息，则根据所述响应消息确定发送所述响应消息的设备是否处于广播接收状态；
步骤S104，若确定至少一个发送所述响应消息的设备处于广播接收状态，则确定所述广播范围内存在接收端设备；
步骤S105，若确定发送所述响应消息的设备均未处于广播接收状态，则确定所述广播范围内不存在接收端设备。
若在发送通信请求后预设时长内接收到针对通信请求反馈的响应消息，则广播源设备可以进一步根据响应消息确定发送该响应消息的设备是否处于广播接收状态。在本实施方式中，对根据响应消息确定发送该响应消息的设备是否处于广播接收状态的方式并不做限制。
例如，在一实施方式中，响应消息中可以携带表征该设备是否处于广播接收状态的信息，广播源设备根据该信息即可确定该设备是否处于广播接收状态；其他设备在接收到广播源设备发送的通信请求时，可以检测是否接收广播，若是，则可以在响应消息中携带表 征该设备处于广播接收状态的信息，若否，则可以不反馈响应消息或在响应消息中携带表征该设备不处于广播接收状态的信息；其他设备可以根据自己的设备类型来确定是否接收广播，例如当该设备是不带显示屏和喇叭的设备时，可以确定不接收广播，或者，其他设备可以在接收到通信请求后输出提示信息，提示用户是否接收广播，根据用户输入的指令来确定是否接收广播。
进一步地，在一实施方式中，所述步骤S20包括：
步骤S201，当根据所述广播接收端信息确定所述广播范围内不存在接收端设备时，将所述广播源设备设置为低功耗模式。
当广播接收端信息包括表征广播范围内是否存在接收端设备的信息时，广播源设备可以进入低功耗模式，以降低广播源设备的功耗。其中，低功耗模式可以是停止广播的模式，或停止广播后进一步按照低功耗运行参数运行的模式，具体可以根据需要设置，在此并不做限制。
进一步地，基于上述第一实施例，提出本发明广播源控制方法第二实施例，在本实施例中，所述步骤S10包括：
步骤S106，当确定所述广播范围内有接收端设备时，基于所述目标无线通信技术获取所述接收端设备发送的设备定位，根据所述设备定位与所述广播源的定位计算得到所述接收端设备与所述广播源设备之间的距离；
在本实施例中，广播接收端信息可以包括广播范围内的接收端设备与广播源设备之间的距离。广播源设备可以在确定广播范围内有接收端设备时，基于目标无线通信技术获取接收端设备发送的设备定位。具体地，广播源设备可以基于目标无线通信技术向外发送通信请求，接收端设备接收到通信请求后，可以反馈响应消息，并可在响应消息中携带该接收端设备的设备定位。广播源设备根据自己的定位以及接收端设备的定位即可计算得到两个设备之间的距离。其中，广播源设备的定位可以基于广播源设备中的定位装置获取，接收端设备的定位可以基于接收端设备中的定位装置获取。
步骤S107，当确定所述广播范围内有接收端设备时，基于所述目标无线通信技术与所述接收端设备进行通信，并基于通信信号的收发时间差和传播速度计算得到所述接收端设备与所述广播源设备之间的距离。
或者，广播源设备可以在确定广播范围内有接收端设备时，基于目标无线通信技术与 接收端设备进行通信，基于通信信号的收发时间差和传播速度来计算得到该接收端设备与广播源设备之间的距离。例如，广播源设备可以记录向外发送通信信号的时间，接收端设备在接收到该通信信号时记录接收时间，并向广播源设备反馈该接收时间，广播源设备计算发送时间和接收时间之差，并处以信号传播速度，即可得到该接收端设备与广播源设备之间的距离。
进一步地，在一实施方式中，所述步骤S20包括：
步骤S202，当确定所述广播范围内有接收端设备时，根据所述广播接收端信息确定各所述接收端设备与所述广播源设备之间的距离中的最远距离；
当广播接收端信息包括广播范围内的接收端设备与广播源设备之间的距离时，广播源设备可以根据接收端设备的距离来设置广播源设备的广播参数。具体地，广播源设备可以根据广播接收端信息确定各个接收端设备与广播源设备之间的距离中的最远距离。例如，当广播范围内有3个接收端设备，与广播源设备的距离分别为1米、2米和3米，那么最远距离为3米。
步骤S203，根据所述最远距离设置所述广播源设备的广播重传次数、广播发射功率和/或广播发送时间间隔，其中，所述最远距离越远时所设置的所述广播重传次数越大，所述最远距离越远时所设置的所述广播发射功率越大，所述最远距离越远时所设置的所述广播发送时间间隔越长。
广播源设备可以根据最远距离设置广播源设备的广播重传次数、广播发送功率和广播发送时间间隔中任意一项或多项参数，具体设置哪些参数，可以根据需要设置，在此并不做限制。根据最远距离设置广播重传次数时，可以是当最远距离越远时，设置的广播重传次数越大，以保证距离远的接收端设备所接收的广播数据的准确性，同时也实现当接收端设备都距离广播源设备较近时，通过设置较低的广播重传次数来降低广播源设备的功耗。根据最远距离设置广播发射功率时，可以是最远距离越远时，设置的广播发射功率越大，以保证距离远的接收端设备所接收的广播数据的准确性，同时也实现当接收端设备都距离广播源设备较近时，通过设置较低的广播发射功率来降低广播源设备的功耗。根据最远距离设置广播发送时间间隔时，可以是最远距离越远时，设置的广播发送时间间隔越长，以保证距离远的接收端设备所接收的广播数据的准确性，同时也实现当接收端设备都距离广播源设备较近时，通过设置较短的发送时间间隔来降低广播时延。
在具体实施方式中，可以预先设置不同的距离区间对应的不同的广播重传次数、广播 发送功率和广播发送时间间隔，确定最远距离所属的距离区间，按照该距离区间对应的广播重传次数、广播发送功率和广播发送时间间隔进行广播。
进一步地，在一实施方式中，所述步骤S10包括：
步骤S108，每隔预设时间间隔基于目标无线通信技术检测所述广播源设备广播范围内的广播接收端信息；
广播源设备可以每隔预设时间间隔基于目标无线通信技术检测广播范围内的广播接收端信息。其中预设时间间隔可以根据需要设置，在此并不做限制。
所述步骤S20包括：
步骤S204，每次检测到所述广播接收端信息后，将当次检测到的所述广播接收端信息与上一次检测到的所述广播接收端信息相比较；
广播源设备可以每次检测到广播接收端信息后，将当次检测到的广播接收端信息与上一次检测到的广播接收端信息进行比较，以确定当次检测到的广播接收端信息相比于上一次是否发生变化，从而确定是否要对广播参数进行调整。
步骤S205，若当次检测到的所述广播接收端信息相比于上一次检测到的所述广播接收端信息的变化达到预设参数变更条件，则根据当次检测到的所述广播接收端信息更新所述广播源设备的广播参数，并按照更新后的广播参数进行广播；
若当次检测到的广播接收端信息相比于上一次检测到的广播接收端信息的变化达到预设参数变更条件，则广播源设备可以根据当次检测到的广播接收端信息更新广播源设备的广播参数，也即重新设置广播参数，并按照新设置的广播参数进行广播。其中，预设参数变更条件可以根据需要设置，在此并不做限制。例如，当上一次广播接收端信息表征广播范围内存在接收端设备，当次广播接收端信息表征广播范围内不存在接收端设备时，可以认为达到预设参数变更条件，以及，当上一次广播接收端信息表征广播范围内不存在接收端设备，当次广播接收端信息表征广播范围内存在接收端设备时，可以认为达到预设参数变更条件。又如，当根据当次广播接收端信息确定的最远距离与根据上一次广播接收端信息确定的最远距离之差的绝对值大于一定阈值时，可以认为达到预设参数变更条件。
步骤S206，若当次检测到的所述广播接收端信息相比于上一次检测到的所述广播接收端信息的变化未达到预设参数变更条件，则按照所述广播源设备当前的广播参数继续进行广播。
若当次检测到的广播接收端信息相比于上一次检测到的广播接收端信息的变化未达到 预设参数变更条件，则广播源设备可以按照广播源设备当前的广播参数继续进行广播，例如保持低功耗模式，保持当前的广播发射功率、广播发送时间间隔和广播重传次数等。
