可见, 通过根据接收到的卡拉 OK设备在采集所述歌唱声音时的状态 数据对卡拉 OK设备采集歌唱声音得到的歌唱数据进行增益补偿, 确定增 益补偿后的歌唱数据对应的评价信息, 供物联网终端呈现出来, 从而减少 了卡拉 OK设备在采集歌唱声音时由于设备状态的影响而导致的采集到的 歌唱数据相对于歌唱声音的增益损失, 从而减少了卡拉 OK设备状态对于 对歌唱声音的评价的真实性所造成的影响, 由此, 使反馈结果真实有效, 所呈现出来的评价信息也就更为真实地反映了用户的歌唱水平。
其中,所述卡拉 OK设备上可以部署卡拉 OK设备监控模块, 包括但不 限于以下部分: 话筒监控模块, 音响监控模块等。 则所述卡拉 OK设备在 采集所述歌唱声音时的状态数据为由该卡拉 OK设备监控模块对所述卡拉 OK设备的状态进行数据采集得到并将其报告给所述任一物联网终端。

当然, 本领域技术人员还应当了解, 由于卡拉 OK设备技术的不断发 展, 在这六种状态数据的基础上还可能增加其他状态数据, 这也在本说明 书的记载范围内。
这里, 本底噪声 (ground noise )是指设备自行产生的信号。

在本发明实施例中, 所述任一物联网终端可以包括客户端模块或 K房 服务模块。 其中, 客户端模块可以是部署在用户随身设备上的装置, 比如 安装在手机、 PDA、 笔记本或平板电脑等设备上的客户端软件。 K房服务 模块可以是部署在 K房设备上的装置,比如直接安装在 K房设备上的软件。
为了将本发明实施例进一步阐述清楚明白, 下面给出本发明实施例的 优选实施方式。
在本优选实施方式中, 基于物联网的系统包括物联网服务平台、 作为 物联网应用模块的数据处理模块、 多个服务模块、 多个客户端和——部署 在多个卡拉 OK设备上的多个监控模块, 参见图 2。
以卡拉 OK场景为例, 服务模块具体为 K房服务模块, 基于该系统的 实现方法包括如下步骤:
步骤 201, 用户注册帐号后, 在数据处理模块存储了用户的帐号信息; 用户注册信息包括帐号, 还可以包括密码和 /或昵称等信息;
步骤 202, 用户通过客户端用该帐号登录, 并连接到某个 KTV房的某 个卡拉 OK设备,物联网服务平台将用户信息发送给该 KTV房的 K房服务 模块, 该 K房服务模块展示出用户若干信息, 如得分情况, 得分最高的歌 曲等;
步骤 203, 用户进行歌唱, 客户端将部署在该卡拉 OK设备上的监控模 块报告的歌唱数据和设备状态数据(包括话筒的本底噪声 /失真电平, 录音 设备的本底噪声 /失真电平, 放音设备的本底噪声 /失真电平等)传输给物联 网服务平台;
步骤 204,物联网服务平台根据该设备状态数据对该歌唱数据进行预处 理, 得到预处理后的处理结果数据;
预处理方法如下:
设 d表示 K房设备编号, 演唱数据为 v, 话筒的本底噪声为 ml, 话筒 的失真电平为 m2, 录音设备的本底噪声为 rl, 录音设备的失真电平为 r2, 放音设备的本底噪声为 pl,放音设备的失真电平为 p2, 处理结果数据为 p; 预处理方法表示为:
Ρ=ν+Διη1+Δηι2+ΔΓ1+ΔΓ2+Δρ1+Δρ2, 其中△表示取反, 即如果 ml 是负值, 则 Ami为正值; 或者,
考虑到不同 K房的卡拉 OK设备的失真可能不同, 则预处理方法表示 为: p=F(d,v,ml ,m2,rl ,r2,p 1 ,p2);
其中, F表示某种处理算法, 用以对各个不同 K房的不同设备采用不 同的修正算法以得到剔除设备差异后的一致性的处理结果。例如,对某个 K 房(编号 d=0001 ) 的处理方法为:
ρ=ν+Διη1+Δηι2+ΔΓΐ+ΔΓ2+Δρ1+Δρ2ο
而对另一个 Κ房(编号 d=0002 ) 的处理方法可能为:
p=v+0.5x \ml+l.lx \m2+0.8x \rl+0.9x \r2+ \pl+1.04x \p2。
其中, 各个 K房设备的参数系数是预先设定的, 其设置方法为: 先以 某典型设备为基准(其参数系数设定为 1 ),如果 K房设备比典型设备好(失 真小), 则设定比 1小的系数, 如果 K房设备比典型设备差 (失真大), 则 设定比 1 大的系数。 设备好, 表现为设备的电性能参数规格更高、 技术更 先进、 设备更新, 设备差, 表现为设备的电性能参数低、 设备老旧等。 比 如对于话筒来说, 其主要性能参数包括灵敏度、 频率响应、 指向性、 动态 范围、 输出阻抗等, 通过这些性能参数, 可以在一定程度上识别出话筒的 好坏, 对这些值进行量化比较可以对不同话筒的性能有个参考比较, 从而 赋予不同的系数。 将影响设备性能的这些参数进行统筹考虑后, 就可以得 出该 K房设备的参数系数。
步骤 205, 物联网服务平台将处理结果数据 p交给数据处理模块; 步骤 206,数据处理模块将该处理结果数据进行打分, 给出用户此次歌 唱的分数, 通过物联网服务平台返回给客户端模块和 /或 K房服务模块; 并 将用户积分、 该歌曲的若干最高得分情况、 用户排名等信息通过物联网服 务平台返回给客户端和 /或 K房服务模块;
步骤 207, 客户端和 /或 K房服务模块将数据处理模块返回的信息呈现 出来或者供用户查看这些返回的信息;
步骤 208, K房服务模块可以展示出在本 KTV房进行卡拉 OK歌唱的 所有用户的歌唱排名情况。
步骤 209,数据处理模块可以保存用户的歌唱历史记录, 并自动根据用 户得分情况生成拿手歌列表通过物联网服务平台反馈给客户端模块, 方便 用户选择。
步骤 210,数据处理模块可以根据用户的歌唱数据提供歌唱技巧改进信 息。
上述基于该系统的实现方法的步骤之间顺序可能存在互相交叉, 也可 能通过简化步骤来简化方案等, 在此不再赘述。 也就是说, 对于本领域技 术人员来说, 在不违背本发明实施例精神实质的前提下, 上述实现方法的 任何可能的变形都在说明书记载的范围之内。
