Description

一种传输信号的方法和装置 技术领域
本发明实施例涉及信息技术领域，并且更具体地，涉及一种传输信号的方法和装置。
背景技术
随着物联网(Internet of Things，简称“IoT”)的兴起，传统的耳机领域也发生着改变，除了放音功能外，还逐渐加上心率检测、运动记步等信息交互的智能特性。
目前，已知一种有线耳机，能够通过主机端与耳机接口相对应的音频信号通路进行通信传输。其主要的通信过程如下：(1)终端将需要下发到耳机的数据进行编码和调制；(2)终端将已调信号进行数模转换；(3)终端通过与耳机接口相连的耳机线的左声道线或右声道线将数模转换后的调制信号传给耳机；(4)耳机对接收到的信号进行解调和解码。此过程中，一方面，信号的传输由一根声道线(例如，左声道线或者右声道线)来传输，需要在接收端通过载波恢复模块将载波恢复出来，以进行信号解调。传统的载波恢复通常是采用锁相环等电路进行；另一方面，信号的解码也需要通过数字电路来完成。因此，用于解调和解码的数字电路结构较为复杂，成本也相对较高。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明的一部分实施例，而不是全部实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创 造性劳动的前提下所获得的所有其他实施例，都应属于本发明保护的范围。
应理解，本发明实施例所涉及的穿戴式通信设备可以为手环、耳机等可以通过有线通信或者无线通信方式与终端设备进行通信的可穿戴设备。该可穿戴设备可以用于实现心率检测、运动记步等功能。
以下，不失一般性，以终端设备向耳机传输信号为例，详细说明根据本发明实施例的传输信号的方法的具体过程。
应理解，本发明实施例涉及的耳机，包括听筒(也可称之为耳塞或耳罩)，听筒中包括扬声器。耳机通过耳机线与终端连接，例如，耳机线包括四段式引脚(或者说，四段式耳机接头)，该四段式引脚可以插入终端的四段式音频接口。
本发明实施例涉及的终端设备可以是各种音源设备，且该终端设备包括四段式音频接口，与耳机的四段式引脚连接后，可以为耳机提供电源，驱动耳机的扬声器(也可称之为喇叭)和麦克风，该四段式音频接口例如为有源3.5mm插孔。具体地，该终端设备可以是便携式或台式电子设备，例如可以是手机、平板电脑、音乐播放器或录音机等各种手持终端，而不仅限于通信终端。
还应理解，本发明所示出的终端设备与耳机之间传输信号的方法仅为示例性说明，而不应对本发明构成任何限定。本发明实施例同样适用于除耳机之外的其他可穿戴通信设备。
图1是从设备交互的角度示出的根据本发明实施例的传输信号的方法100的示意性流程图。应理解，图1示出了一种传输信号的方法的详细的通信步骤或操作，但这些步骤或操作仅是示例，本发明实施例还可以执行其它操作或者图1中的各种操作的变形。此外，图1中的各个步骤可以按照与图1呈现的不同的顺序来执行，并且有可能并非要执行图1中的全部操作。
下面详细说明方法100的详细步骤。
如图1所示，该方法100包括：
S102，终端设备对原始数据进行编码得到原始编码序列。
具体而言，该原始数据可以为由二进制数“1”和“0”构成的序列。通过对该原始数据进行编码可以得到编码序列。作为示例而非限定，该编码可以为曼彻斯特编码，该编码序列可以为曼彻斯特序列。为便于区分和说明，将对该原始数据编码得到的序列称为原始曼彻斯特序列。以下，为便于理解 和说明，以曼彻斯特编码后得到的曼彻斯特序列为例，说明本发明实施例的传输信号的方法的具体过程。
具体地，曼彻斯特编码可以将二进制数“1”用“10”表示，将“0”用“01”表示。图2示出了原始数据，以及对原始数据进行曼彻斯特编码后得到的原始曼彻斯特序列的示意图。其中，图2a是通过方形波来表示原始数据“10101”的示意图。图2b是对原始数据进行曼彻斯特编码得到的曼彻斯特序列“1001100110”的方形波的示意图。
S104，终端生成载波信号。
具体而言，载波信号用于对原始曼彻斯特序列进行调制处理。作为示例而非限定，该调制方法可以为幅移键控(Amplitude Shift Keying，简称“ASK”)调制处理。应理解，ASK调制作为调制的一种方法，仅用于作为示例性说明，而不应对本发明构成任何限定，本发明也不应限于此。例如，该调制方法还可以包括相移键控(Phase Shift Keying，简称“FSK”)调制、频移键控(Frequency Shift Keying，简称“PSK”)等等。以下，为方便理解和说明，以ASK调制为例，说明本发明实施例的传输信号的方法的具体过程。
需要说明的是，这里所说的载波信号可以理解为用于承载待传输数据或者待传输信息的信号，载波信号本身并不承载信号。载波信号用于对上述原始曼彻斯特序列进行调制处理，可以得到调制波信号。
示例性地，该载波信号可以为单频点的正弦波。
可选地，该载波信号可以由不同频点的两个正弦波调制得到。具体地，该载波(为便于区分和说明，记作目标载波)信号可以为第一频率的正弦波(为便于区分和说明，记作第一载波)和第二频率的正弦波(为便于区分和说明，记作第二载波)调制得到。为保证通信频率落在20kHz以内的频段，该第一频率与第二频率的频率差值大于或等于20kHz。例如，第一频率为21kHz，第二频率为1kHz；或者，第一频率为30kHz。第二频率为10kHz。
具体来说，假设第一载波为yc1，第二载波为yc2，调幅形成的目标载波为yc。则：
yc1＝sin(2π*fc1*t)；
yc2＝sin(2π*fc2*t)；
yc＝yc1*yc2。
其中，fc1为yc1的频率(即，第一频率)，fc2为yc2的频率(即，第二频 率)，且，∣fc1-fc2∣≥20kHz。则yc的包络频率为2fc2，通信速率为fc2。
图3是对第一载波和第二载波进行调制得到目标载波的示意图。其中，图3a是第一频率(例如，fc1＝21kHz)的正弦波的示意图，图3b是第二频率(例如，fc2＝1kHz)的正弦波的示意图，图3c是对第一频率的正弦波和第二频率的正弦波进行调制后得到的目标载波的示意图。
应理解，这里所列举的第一频率与第二频率的取值仅为示例性说明，不应对本发明构成任何限定，只要第一频率与第二频率的频率差值满足大于或等于20kHz，均落入本发明的保护范围内。
还应理解，这里所列举的用于调制载波信号的第一载波和第二载波仅为示例性说明，不应对本发明构成任何限定，本发明对于用于调制调幅波的信号类型和数量并未特别限定。
S106，终端基于载波信号，对原始曼彻斯特序列进行ASK调制获得调制波信号。
具体而言，终端基于在S104调制得到的载波信号，对S102得到的原始曼彻斯特序列进行ASK调制。应理解，ASK调制的方法与现有技术相同，为了简洁，这里省略对原始曼彻斯特序列进行ASK调制的详细说明。
图4示出了通过目标载波对原始曼彻斯特序列进行ASK调制得到的调制波的示意图。其中，图4a是目标载波的示意图；图4b是原始曼彻斯特序列的示意图。图4c是通过目标载波对原始曼彻斯特序列进行ASK调制后得到的调制波的示意图。可以看到，ASK调制后的信号波呈现出类似正弦波的不连续波形。
S108，终端向耳机发送调制波信号。
具体而言，终端可以通过音频编解码单元(Audio Codec Unit)对调制波信号进行数模转换，并经过音频放大单元(Audio Amplifier Unit)的放大处理后，将处理后的调制波信号发送给耳机。具体地，可以通过连接于终端与耳机之间的耳机线传输调制波信号。
应理解，耳机线的一端包括四段式引脚，该四段式引脚包括左声道L引脚、右声道R引脚、接地G引脚与麦克风M引脚。耳机通过耳机线的四段式引脚与终端连接，具体地，该四段式引脚用于与终端的四段式音频接口连接，终端分别通过左声道L引脚、右声道R引脚和麦克风M引脚驱动耳机的左右喇叭和麦克风。其中，与左声道L引脚连接的耳机线为左声道L线， 与右声道R引脚连接的耳机线为右声道R线，与麦克风M引脚连接的耳机线为麦克风M线，与接地G引脚连接的耳机线为地线。
在本发明实施例中，耳机可以通过左声道L线或者右声道R线(即，第一声道线的一例)从终端接收调制波信号。
可选地，S108终端向耳机发送调制波信号：
终端通过第一声道线向耳机发送该调制波信号；
该方法100还包括：
终端通过第二声道线向耳机发送载波信号，该载波信号用于耳机对接收到的调制波信号进行解调，以获得待解码信号。
具体而言，终端可以通过左声道L线和右声道R线中的任意一根声道线(即，第一声道线的一例)发送调制波信号，并通过另一根声道线(即，第二声道线的一例)发送载波(例如，上述目标载波)信号。具体地说，第一声道线可以为左声道L线，第二声道线可以为右声道R线；或者，第一声道线可以为右声道R线，第二声道线可以为左声道L线。本发明对此并未特别限定。
需要说明的是，在当前技术中，接收端(例如，耳机)可以通过数字电路对接收到的调制波信号进行解调，这需要复杂的载波恢复模块来获取载波。进一步地，作为一个可选的实施例，目标载波信号可以由两个载波调制得到，即，目标载波不同于单频点载波，其对应的载波恢复模块更加复杂，因此，也就需要更加复杂的数字电路才能实现对调制波信号的解调。
在本发明实施例中，终端(即，发送端的一例)通过第二声道线将载波信号直接发送到耳机(即，接收端的一例)，使得耳机可以直接根据接收到的载波信号进行解调处理，省去了复杂的载波恢复模块，从而降低数字电路的复杂度。
以下详细说明对调制波信号进行解调和解码(或者说，译码)的具体过程。
S110，耳机对接收到的调制波信号进行解调，得到待解码信号。
具体而言，耳机在接收到终端分别通过第一声道线发送的调制波信号和通过第二声道线发送的载波信号后，可以直接由模数转换器(Analog to Digital Converter，简称“ADC”)采集信号(包括调制波信号和载波信号)。例如，由左声道线传输调制波信号ym，由右声道线传输载波信号yc，则对调 制波信号进行解调的过程可以如下式所示：
ydm1＝ym*yc，
其中，ydm1是解调后的信号，也即是待解码信号。
可选地，可以通过低通滤波器(Low Pass Filter，简称“LPF”)对高频信号进行滤除以得到待解码信号。
图5示出了通过对调制波信号进行解调的示意图。其中，图5a是调制波信号ym的示意图；图5b是解调信号yc的示意图；图5c是解调信号ydm1的示意图；图5d是经低通滤波后的信号ydm2的示意图。可以看到，经低通滤波后的信号ydm2滤除了频带以外的信号和多余的频段、频率的干扰。
S112，耳机对待解码信号进行波形整形处理，得到方波信号。
具体而言，耳机可以通过波形整形算法，对待解码信号进行波形整形处理。例如，可以通过比较器输出阈值，根据比较器输出的阈值，对波形进行整形处理，得到方波信号。
在本发明实施例中，耳机在得到方波信号之后，便可以根据多个时间间隔特征值与多个编码序列(例如，曼彻斯特序列)的映射关系，对该方波信号进行解码处理，得到原始数据。
可选地，根据多个时间间隔特征值与多个编码序列的映射关系，对该方波信号进行解码处理，得到原始数据，包括：
根据该多个时间间隔特征值与该第一映射关系，对该方波信号进行解码，得到解码结果，该解码结果包括至少一个该第一曼彻斯特序列、至少一个该第二曼彻斯特序列和至少一个该第三曼彻斯特序列；
根据该解码结果所包括的比特位，对该解码结果进行还原处理，得到原始曼彻斯特序列，该原始曼彻斯特序列是对该原始数据进行编码得到的序列；
对该原始曼彻斯特序列进行第二解码处理，得到该原始数据。
以下具体描述解码处理的过程。
S114，耳机获取方波信号中的多个时间间隔特征值。
具体而言，方波信号可以理解为由多个高电平和多个低电平组成的波形。在方波信号中，可以用高电平表示第一预设值。时间间隔可以理解为任意两个相邻的第一预设值所对应的高电平之间的间隔，或者说，时间间隔可以理解为低电平的时长。换句话说，任意两个相邻的第一预设值所对应的高 电平之间具有时间间隔。
可选地，S114耳机获取方波信号中的多个时间间隔特征值，包括：
对该调制波信号设置包头信号；
根据该包头信号，获取该包头信号的周期、该调制波信号的脉冲宽度，以及在比较器输出的阈值大于零时该方波信号中每个方波的上升沿或下降沿与该调制波信号的脉冲起始点之间的边沿偏差，其中，该比较器用于对该调制波信号进行该波形整形处理；
根据该调制波信号的周期、脉冲宽度以及该边沿偏差，获取该多个时间间隔特征值。
具体而言，由于耳机在接收到终端发送过来的调制波信号时，并不预先获知该调制波信号所对应的原始数据，故，无法根据确定调制波信号的波形中的时间间隔特征值分别对应于哪个时间价格特征值。本发明实施例可以通过为调制波信号设置包头信号的方式，获取时间间隔特征值所包括的三个特征值，即，上述t1、t2和t3。
举例来说，假设包头信号为十六进制数0xff，其被终端编码和调制后的调制波形图可如图6所示，对该包头信号的调制波进行波形整形处理后得到的方波图也可如图6所示。
图6示出了包头信号为十六进制数0xff的调制波形图和方波图。可以理解，十六进制数0xff可以对应于二进制数1111 1111，其对应的曼彻斯特序列序列为1010 1010 1010 1010。故可以由图6中所示的根据比较器输出的阈值，对调制波进行波形整形处理的过程，可以得到包头信号的周期Ts、脉冲宽度Tw以及在比较器输出的阈值大于零时所述方波与所述调制波信号的脉冲起始点之间的边沿偏差Tu。通过获取包头数据的上升沿和下降沿时刻，分别保存为数组rise[N]和数组fall[N]，其中N为包头信号中脉冲的个数。则有：
Figure PCTCN2016093511-appb-000001
Figure PCTCN2016093511-appb-000002
Figure PCTCN2016093511-appb-000003
由上文描述可知，时间间隔特征值可以通过t(i)＝rise(i)-fall(i-1)来计算。由此，可以得出上述三个特征值。具体如下：
t1＝Ts-Tw
t2＝Ts+2*Tu
t3＝2*Tu
由此可以计算得到三个特征值。
应理解，以上列举的用于获取时间间隔特征值所包括的三个特征值的具体方法，Ts、Tw以及Tu的计算式以及t1、t2和t3的计算式仅为示例性说明，不应对本发明构成任何限定。当包头信号不同时，Ts、Tw以及Tu的计算式不同，t1、t2和t3的计算式也不同，但t1、t2和t3的取值不变。通过其他的包头数据，获取t1、t2和t3的取值的方法均落入本发明的保护范围内。
由上文描述可知，方波信号是根据比较器输出的阈值对波形进行整形处理得到的，因此，每个高电平的时间长度可以是小于或者等于1/2Ts的。也就是说，任意两个连续的第一预设值所对应的两个高电平之间具有时间间隔，该时间间隔即为2Tu，即，t3。
S116，耳机获取第一映射关系。
具体而言，该第一映射关系用于指示多个时间间隔特征值与多个编码序列(例如，曼彻斯特序列)的一一映射关系。
可选地，该多个时间间隔特征值包括：第一特征值、第二特征值和第三特征值，该多个编码序列包括第一曼彻斯特序列、第二曼彻斯特序列和第三曼彻斯特序列，每个编码序列由第二预设值和所述第一预设值构成，该方波信号用于表示该第一预设值和该第二预设值，
该第一映射关系具体包括：
该第一特征值与第一曼彻斯特序列对应，该第一曼彻斯特序列具体为：在第一比特位取值为该第一预设值，在第二比特位取值为该第二预设值；
该第二特征值与第二曼彻斯特序列对应，该第二曼彻斯特序列具体为：在该第一比特位取值为该第一预设值，在该第二比特位取值为该第二预设值，在该第三比特位取值为该第二预设值；
该第三特征值与第三曼彻斯特序列对应，该第三曼彻斯特序列具体为：在该第一比特位取值为该第一预设值，在该第二比特位取值为该第二预设值；
其中，该时间间隔特征值用于表征任意两个相邻的高电平之间的时间间隔，该第一比特位为与该时间间隔特征值对应的两个相邻高电平中的第一个 高电平对应的比特位，该第二比特位为该第一比特位之后的第一个比特位，该第三比特位为该第二比特位之后的第一个比特位。
在本发明实施例中，由于终端设备发送的调制波信号是经过曼彻斯特编码的，即，第一预设值可以为“1”，第二预设值可以为“0”。
曼彻斯特编码得到的序列所对应的方形波具有以下三种类型：
1)当曼彻斯特序列为“1010”或者“0101”(或者说，曼彻斯特序列为“101”)时，即，分别对应于原始数据“11”或“00”，对应的方形波之间具有时间间隔特征的第一特征值t1。即，第一特征值与第一曼彻斯特序列对应，该第一曼彻斯特序列为“10”；
2)当曼彻斯特序列为“1001”时，即，分别对应于原始序列“10”，对应的方形波之间具有时间间隔特征的第二特征值t2。即，第二特征值与第二曼彻斯特序列对应，该第二曼彻斯特序列为“100”；
3)当曼彻斯特序列为“0110”(或者说，曼彻斯特序列为“11”)时，即，分别对应于原始序列“01”，对应的方形波之间具有时间间隔特征的第三特征值t3；即，第三特征值与第三曼彻斯特序列对应，该第三曼彻斯特序列为“11”。
图7示出了多个时间间隔特征值与多个曼彻斯特序列的一一映射关系的示意图。由图可以看到，时间间隔可以表示为两个相邻方形波中第二个方形波出现上升沿的时刻与第一个方形波出现下降沿的时刻的时间差，或者，也可以理解为低电平的时间长度。其中，第一比特位可以对应于该两个相邻方形波(具体地，高电平)中第一个方形波(具体地，高电平)所对应的比特位。
S118，耳机根据第一映射关系，对方波信号进行解码，得到解码结果。
由S116可知，时间间隔特征的三个特征值分别对应于曼彻斯特序列的三种取值情况。因此，耳机可以根据解调出的待解码信号，进行解码，以得到解码结果。
再参看图7，当时间间隔特征值为第一特征值t1时，在该时间间隔特征值对应的两个相邻方波中的第一个方波对应的比特位(即，第一比特位)的取值为“1”，在该第一比特位之后的比特位(即，第二比特位)的取值为“0”；当时间间隔特征值为第二特征值t2时，在第一比特位取值为“1”，在第二比特位取值为“0”，在该第二比特位之后的比特位(即，第三比特位)的取值 为“0”；在该时间间隔特征值为第三特征值t3时，在第一比特位取值为“1”，此时，可以继续为第二比特位取值为“1”，也可以根据下一个时间间隔的特征值，为该第二比特位(可以理解，对应于下一个时间间隔而言，该第二比特位为下一个时间间隔的第一比特位)取值。
需要说明的是，图7示出的波形图的最后一个脉冲之后的波形是不可知的，可能是高电平，也可能低电平。也就是说，在方波信号的最后一个高电平之后，无法确定时间间隔特征值。因此，该最后一个高电平所对应的比特位以及后续的比特位无法确定其对应的曼彻斯特码的取值。
S120，对该解码结果进行还原处理，得到原始编码序列。
由于曼彻斯特序列是对二进制序列进行曼彻斯特编码得到的，即，二进制数“1”对应曼彻斯特序列“10”，二进制数“0”对应曼彻斯特序列“01”，故一个完整的曼彻斯特序列所包含的比特位为2的整数倍。
因此，可以根据在S118中经解码处理得到的解码结果的比特位数来确定最后一个比特位的取值。
可选地，该解码结果为包括S个比特位的曼彻斯特序列，S为大于或等于2的自然数，以及
根据该解码结果所包括的比特位，对该解码结果进行还原处理，得到原始曼彻斯特序列，包括：
在mod(S，2)＝0时，根据所述原始曼彻斯特序列的最后两个比特位在所述方波信号中所对应的波形，确定所述原始数据的最后两个比特位的取值；或者，
在mod(S，2)＝1时，根据所述原始曼彻斯特序列的倒数第二个个比特位在所述方波信号中所对应的波形，确定所述原始数据的最后两个比特位的取值；
根据所述解码结果和所述原始曼彻斯特序列的末两个比特位的取值，确定所述原始曼彻斯特序列。
具体而言，假设该解码结果为包括S个比特位的曼彻斯特序列，当mod(S，2)的值为0时，说明该解码结果与原始曼彻斯特序列之间刚好差了两个比特，即可以对应于如图7所示的最后一个脉冲所对应的两个比特。在图7中，该最后两个比特位的取值为“10”，从而可以得到完整的曼彻斯特序列(即，原始曼彻斯特序列)。当mod(S，2)的值为1时，说明该解码结果 与原始曼彻斯特序列之间刚好差了一个比特。此情况下，根据方波信号所对应的最后一个比特位，补入未体现在方波信号中的比特位的取值。若该解码结果的最后一个比特位为“0”，则再加一个比特位，该比特为取值为“1”，构成“01”；若该解码结果的最后一个比特位为“1”，则再加一个比特位，该比特位的取值为“0”，构成“10”。
在本发明实施例中，S108的解码和S120中的还原处理可以合称为第一解码处理，用于对待解码信号进行处理，以得到原始编码序列。
S122，耳机对原始编码序列进行第二解码处理，得到原始数据。
具体而言，耳机根据曼彻斯特编码的原理，将原始曼彻斯特序列中的“10”解码为“1”，将原始曼彻斯特序列中的“01”解码为“0”，从而恢复出原始数据。
图8示出了由原始曼彻斯特序列解码得到原始数据的过程。其中，图8a示出了原始曼彻斯特序列的示意图；图8b示出了原始数据的示意图。
应理解，以上所列举的曼彻斯特序列作为编码序列的一种形式，仅为示例性说明，不应对本发明构成任何限定，本发明也不应限于此。例如，编码序列也可以为通过其他编码方式进行编码得到的序列。
还应理解，以上所列举的第一预设值为“1”，第二预设值为：“0”，以及第一预设值与高电平的对应关系仅为示例性说明，不应对本发明构成任何限定，例如，该第一预设值也可以为“0”，且可以进一步对应于方波信号中的高电平，该第二预设值也可以为“1”。本发明对此并未特别限定。
因此，本发明实施例的传输信号的方法，根据多个时间间隔特征值和多个编码序列的一一映射关系，以及获取到的多个时间间隔特征值，可以确定所对应的编码序列，从而恢复出原始数据。避免了现有技术中复杂的数字电路去进行解码，使得数字电路结构简单化，进而降低成本。
