具体实施方式
为了使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明作进一步地详细描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的 范围。
本发明提供一种建立通信的方法、装置及终端、路由器，用以解决现有技术中存在的由于繁琐密码输入错误或者丢失导致登陆失败或者登录时间的延长的问题。其中，方法和设备是基于同一发明构思的，由于方法及设备解决问题的原理相似，因此设备与方法的实施可以相互参见，重复之处不再赘述。
本发明实施例提供了一种建立通信的系统，包括终端和路由器。用于实现路由器与终端通过可见光传输WiFi密码等关键配置信息建立通信。还能实现对可见光通信内容解调后的文本化的输出、存档、分享等。申请人在对本发明研究的过程中发现一般的路由器，例如，家庭路由器，都有一个或者多个LED灯，用于指示产品的状态。另外终端设备都有摄像头等图像采集设备。基于此，为了实现更低成本、更安全、更快捷的通信，将智能手机/平板等接收终端，与路由器组成一种建立通信的系统，通过可见光实现通讯。
本发明实施例提供了一种建立通信的系统，如图1所示，该系统包括路由器100及终端200：
路由器100接收触发指示；所述触发指示用于指示向终端200发出终端200接入路由器100的接入信息；在接收到所述触发指示后，将所述接入信息调制为光信号，并通过路由器100中的至少一个发光装置向所述终端200发送所述光信号。
具体的，路由器100在接收到触发指示后，将预设的终端200接入所述路由器100的接入信息调制为高低电平形式表现的电信号，基于路由器100上的发光装置的第一发光状态表示高电平、第二发光状态表示低电平的规则，将所述电信号处理成为光信号，并通过路由器100上的至少一个发光装置向所述终端200发送所述光信号；
终端200采集路由器100上的至少一个发光装置发出的光信号；并对所述发光状态采集装置采集到的光信号进行解调，并将解调后的信息作为接入所述路由器的接入信息，接入所述路由器。
具体的，终端200获取路由器100上的至少一个发光装置发出的光信号；基于所述发光装置的第一发光状态表示高电平、第二发光状态表示低电平的规则，将所述光信号处理成为基于高低电平形式表现的电信号；并将处理成的电信号解调，并将解调后的信息作为接入所述路由器100的接入信息，接入所述路由器100。
本发明实施例提供了一种路由器100，如图2所示，包括N个发光装置101(图2中仅以一个发光装置为例)、处理器102及接收器103。其中，N为正整数
接收器103，用于接收触发指示，所述触发指示用于指示向终端200发出所述终端200接入路由器的接入信息。
处理器102，用于将所述接入信息，调制为光信号，并通过控制所述N个发光装置101中的至少一个发光装置101向所述终端发送所述光信号。
其中触发指示，可以是通过按键触发发送，还可以通过遥控设备触发发送，还可以通过终端设备触发发送等等，具体触发方式本发明实施例不做具体限定。若是通过按键触发发送，则所述路由器100上可以设有触发按键，触发按键与处理器102相连接。若是通过遥控设备触发发送，则可以在路由器100上设有接收触发指示的装置。
例如，当触发按键被按下时，则处理器102接收到用于触发发出所述接入信息的触发指示后，将所述接入信息调制为光信号，然后通过至少一个发光装置101发出。
其中，所述路由器100还包括存储器104，用于存储预设的终端200接入路由器100的接入信息，如图3所示。存储器104，还可以用于存储处理器102执行的程序代码，可以是ROM，RAM，也可以是EEPROM、磁盘存储介质或者其他磁存储设备、或者能够用于携带或存储具有指令或数据结构形式的期望的程序代码并能够由计算机存取的任何其他介质，但不限于此，例如存储器104可以是上述存储器的组合。
所述存储器104与所述处理器102、接收器103及所述发光装置101可以 通过总线连接。本发明实施例中不限定上述部件之间的具体连接介质，本发明实施例在图3中以存储器104、接收器103、处理器102及发光装置101之间通过总线连接，总线在图3中以粗线表示，其它部件之间的连接方式，仅是进行示意性说明，并不引以为限。
进一步地，处理器102将所述接入信息调制为光信号时，具体可以通过以下方式：
将所述接入信息调制为高低电平形式表现的电信号，并基于所述发光装置的第一发光状态表示高电平、第二发光状态表示低电平的规则，将所述电信号处理成为光信号。
进一步地，处理器102在将接入信息调制成基于高低电平形式表现的电信号时，具体可以通过以下方式：
将所述接入信息通过二进制数据形式进行表示，并将二进制数据形式表示的接入信息，调制成基于高低电平形式表现的电信号。
进一步地，处理器102具体可以以下方式将预设的终端200接入路由器100的基于二进制数形式表现的接入信息，调制成基于高低电平形式表现的电信号：
第一种实现方式：将二进制数0调制为第一预设时长的低电平和第二预设时长的高电平组成的电信号，将二进制数1调制为第一预设时长的低电平和第三预设时长的高电平组成的电信号。
其中第二预设时长可以大于第三预设时长，当然第二预设时长也可以小于第三预设时长。但是第二预设时长不能等于第三预设时长。例如，第一预设时长可以为0.56s，第二预设时长可以为0.56s，第三预设时长可以为1.68s。
例如：如图4所示的波形图，可以以0.56s的低电平，0.56s的高电平，周期为1.12s的高低电平组合表示二进制数0；以0.56s的低电平，1.68s的高电平，周期为2.24s的高低电平组合表示二进制数1。
第二种实现方式：
将二进制数0调制为第四预设时长的高电平和第五预设时长的低电平组 成的电信号，将二进制数1调制为第四预设时长的高电平和第六预设时长的低电平组成的电信号。
其中第五预设时长可以大于第六预设时长，当然第五预设时长也可以小于第六预设时长。但是第二预设时长不能等于第三预设时长。
例如：如图5所示的波形图，可以以0.56s的高电平，0.56s的低电平，周期为1.12s的高低电平组合表示二进制数0；以0.56s的高电平，1.68s的低电平，周期为2.24s的高低电平组合表示二进制数1。
其中，路由器100和终端200之间可以预先协商确定所述发光装置101的第一发光状态表示高电平、第二发光状态表示低电平的规则。用户可以预先通过路由器100上的人机接口预先将上述规则设置在路由器100内部，然后可以通过路由器100预先通知给终端200。
其中，发光装置101可以是路由器100上的LED灯，或者其他的能够发出可见光的发光装置均可。
可以预先设置发光装置101的发光状态，例如：设置发光装置101的第一发光状态为点亮，第二发光状态为熄灭。相反也可以。当然还可以根据发光颜色来设置发光状态。或者根据发光的亮度值确定发光状态等等，具体本发明实施例中不作具体限定。
本发明上述实施例提供的方案通过可见光作为一种通讯介质，将终端与路由器通信的接入信息传送给终端，从而使得终端根据接收到的接入信息与路由器建立连接，不再需要输入繁琐的密码等，从而避免了登陆时间延长或者登陆失败的问题的出现。
进一步地，处理器102通过控制所述N个发光装置101中的至少一个发光装置101向所述终端发送所述光信号，通过控制所述N个发光装置101中的设定发光装置101向所述终端发送前导光信号；所述前导光信号携带发送所述光信号的发光装置信息，用于指示终端在接收到所述前导光信号后，从所述发光装置信息对应的发光装置接收所述接入信息对应的光信号。
由于大多数路由器包括多个发光装置101，则有时可以确定用于发送接入 信息调制后的光信号的发光装置是哪个或者哪几个。当然可以预先在出厂时，就可以设定其中一个用于发送该光信号(本发明实施例中光信号指接入信息调制后的光信号)。例如，路由器中靠近边缘的一个发光装置。还可以将确定的用于发送所述光信号的发光装置信息通过前导光信号发送给终端200。
具体的，所述处理器102，在所述N个发光装置101中确定出用于发送所述前导光信号的第一发光装置，及在N个发光装置101中确定出至少一个用于发送所述光信号的第二发光装置，并通过控制确定的第一发光装置发送所述前导光信号；并在发送所述前导光信号后，通过控制所述第二发光装置发送所述光信号；
所述前导电信号携带发送所述光信号的发光装置信息。即，终端200可以根据接收到的所述前导光信号，确定从哪几个发光装置接收接入信息对应的光信号及从各个发送装置接收到的所述光信号的顺序，即终端对所述光信号信号进行解码的顺序。
进一步地，则所述处理器102，可以用于将调制后的光信号拆分为M个子信号，所述M为等于确定的第二发光装置的数量；
所述处理器102在确定的第二发光装置中，确定与拆分的每一个子信号分别对应的一个发光装置101，并针对确定的每个发光装置101分别执行：通过控制该发光装置101发送对应该发光装置101的子信号。
例如：路由器包括M个LED灯，则处理器102可以预先确定用于发送所述光信号的LED灯；若确定用于发送光信号的LED灯为N个(N小于等于M)，将光信号拆分为N个子信号；其中分解后的N个子信号与确定的N个LED灯一一对应。然后通过各个LED灯将其对应的各个子信号发出。
通过上述方式不但能够提高传输数据的速率，还能够降低路由器的电量耗费。
例如：接入信息中的密码包括8位，预先设置用于发送调制后的光信号的LED灯为4个，LED灯1、LED灯2、LED灯3和LED灯4，编号顺序可以根据LED灯在路由器上的位置，每个LED灯负责发送两位密码。则调制后 的光信号(8位密码)平均拆分为4个子信号，子信号1和子信号2和子信号3和子信号4，其中子信号1和子信号2和子信号3和子信号4按照顺序首尾相接组成完整的电信号。预先设置位于最前面的子信号1对应LED1，子信号2对应LED2，子信号3对应LED3，子信号4对应LED4。
本发明实施例还提供了一种终端，如图6所示，该终端200包括：
发光状态采集装置201，用于采集路由器100上的至少一个发光装置101发出的光信号。
可选地，发光状态采集装置201可以是摄像头等图像采集设备。
处理器202，用于对所述发光状态采集装置采集到的光信号进行解调，并将解调后的信息作为接入所述路由器的接入信息，接入所述路由器。
具体的，所述处理器202基于所述发光装置101的第一发光状态表示高电平、第二发光状态表示低电平的规则，将发光状态采集装置201采集到的光信号处理成为基于高低电平形式表现的电信号；并将处理成的电信号解调，并将解调后的信息作为接入所述路由器100的接入信息，接入所述路由器100。
可以预先设置发光装置101的发光状态，例如：设置发光装置101的第一发光状态为点亮，第二发光状态为熄灭，同理相反也可以。当然还可以根据发光颜色来设置发光状态。或者根据发光的亮度值确定发光状态等等，具体本发明实施例中不作具体限定。
其中，终端200和路由器100之间可以预先协商确定所述发光装置101的第一发光状态表示高电平、第二发光状态表示低电平的规则。还可以路由器100预先通知给终端200。
可以预先确定发光装置101的发光状态，例如：确定发光装置101的第一发光状态为点亮，第二发光状态为熄灭。相反也可以。当然还可以根据发光颜色来确定发光状态。或者根据发光的亮度值确定发光状态等等，具体本发明实施例中不作具体限定。
本发明上述实施例提供的方案通过可见光作为一种通讯介质，将终端与路由器通信的接入信息传送给终端，从而使得终端根据接收到的接入信息与 路由器建立连接，不再需要输入繁琐的密码等，从而避免了登陆时间延长或者登陆失败的问题的出现。
进一步地，在将处理成的电信号解调，将解调后的信息作为接入所述路由器100的接入信息，接入所述路由器100时，所述处理器102具体用于：
将处理成的电信号解调为二进制数的形式；并将解调得到的二进制数对应的信息作为接入所述路由器100的接入信息，接入所述路由器100。
可选地，在将处理成的电信号解调为二进制数的形式时，所述处理器102具体可以但不仅限于以下方式：
第一种实现方式：
识别处理成的电信号中的各个低电平，分别对各个低电平和各个低电平后的高电平进行解调：若经过低电平后再延长第一预设时长阈值后为高电平，将低电平和低电平后的高电平解调为二进制数1，若经过低电平后再延长第一预设时长阈值后为低电平，将该低电平和该低电平后的高电平解调为二进制数0。
第二种实现方式：
识别处理成的电信号中的各个低电平，分别对各个低电平和各个低电平后的高电平进行解调：若经过低电平后再延长第一预设时长阈值后为高电平，将低电平和低电平后的高电平解调为二进制数0，若经过低电平后再延长第一预设时长阈值后为低电平，将该低电平和该低电平后的高电平解调为二进制数1。
第三种实现方式：
识别处理成的电信号中的各个高电平，分别对各个高电平和各个高电平后的低电平进行解调：若经过高电平后再延长第二预设时长阈值后为高电平，将高电平和高电平后的低电平解调为二进制数1，若经过高电平后再延长第二预设时长阈值后为低电平，将该高电平和该高电平后的低电平解调为二进制数0。
第四种实现方式：
识别处理成的电信号中的各个高电平，分别对各个高电平和各个高电平后的低电平进行解调：
若经过高电平后再延长第二预设时长阈值后为高电平，将高电平和高电平后的高电平解调为二进制数1，若经过高电平后再延长第二预设时长阈值后为低电平，将该高电平和该高电平后的低电平解调为二进制数0。
第五种实现方式：
识别处理成的电信号中的各个低电平，分别对各个低电平和各个低电平后的高电平进行解调：若经过低电平后的高电平持续时长处在第一预设时间范围内，将低电平和低电平后的高电平解调为二进制数1，若经过低电平后的高电平的持续时间处在第二预设时间范围内，将该低电平和该低电平后的高电平解调为二进制数0。
第六种实现方式：
识别处理成的电信号中的各个高电平，分别对各个高电平和各个高电平后的低电平进行解调：若经过高电平后的低电平持续时长处在第三预设时间范围内，将高电平和高电平后的低电平解调为二进制数1，若经过高电平后的低电平的持续时间处在第四预设时间范围内，将该高电平和该高电平后的低电平解调为二进制数0。
需要说明的是，电信号中在低电平后为高电平，或者在高电平后为低电平，编码时高低电平相互交替出现。
其中，若路由器100的调制方式采用第一种实现方式，则终端200的解调方式可以采用第一种实现方式或者第二种实现方式或者第五种实现方式。并且第一预设时长阈值是根据第一预设时长和第二预设时长和第三预设时长确定的。需要第一预设时长阈值小于第二预设时长和第三预设时长中的最小值与第一预设时长之和，且大于第二预设时长和第三预设时长中的最小值。
若路由器100的调制方式采用第一种实现方式中第二预设时长大于第三预设时长，则终端200的解调方式可以采用第二种实现方式或者第五种实现方式。若路由器100的调制方式采用第一种实现方式中第二预设时长小于第 三预设时长，则终端200的解调方式可以采用第一种实现方式或者第五种实现方式。若路由器100的调制方式采用第一种实现方式中第二预设时长大于第三预设时长，则终端200的解调方式可以采用第二种实现方式或者第五种实现方式。
例如：路由器100的调制方式如图4所示，从图4中可以看出无论“0”和“1”均以0.56s的低电平开始，不同的是高电平的持续时间不同。二进制数0的高电平的持续时间为0.56s，二进制数1的高电平的持续时间为1.68s。所以可以根据高电平后低电平的持续时间区别“0”和“1”。为了可靠起见，需要考虑数据传输延迟以及高低电平的持续时间。解调时，0.56s低电平后的延时需要大于0.56s，但不能大于1.12s。
若路由器100的调制方式采用第二种实现方式，则终端200的解调方式可以采用第三种实现方式或者第四种实现方式或者第六种实现方式。并且第一预设时长阈值是根据第四预设时长、第五预设时长和第六预设时长确定的。需要第二预设时长阈值小于第五预设时长和第六预设时长中的最小值与第四预设时长之和，且大于第五预设时长和第六预设时长中的最小值。
若路由器100的调制方式采用的第二种实现方式中第五预设时长大于第六预设时长，则终端200的解调方式可以采用第三种实现方式或者第六种实现方式。若路由器100的调制方式采用第二种实现方式中第五预设时长小于第六预设时长，则终端200的解调方式可以采用第四种实现方式或者第六种实现方式。
例如：路由器100的调制方式如图5所示，从图5中可以看出无论“0”和“1”均以0.56s的高电平开始，不同的是低电平的持续时间不同。二进制数0的低电平的持续时间为0.56s，二进制数1的低电平的持续时间为1.68s。所以可以根据高电平后低电平的持续时间区别“0”和“1”。比如设置第一预设时长阈值＝(0.56s+1.12s)/2＝0.84s。假设，将接入信息表示为二进制数后是：101010，则调制后的电信号如图7中a图所示，利用第一预设时长阈值为0.84s进行解码，解码后如图7中b图所示。
可选地，所述处理器202还用于接收用于指示开启所述发光状态采集装置201的指示信号后，控制开启所述发光状态采集装置201。因此，在处理器202未接收到指示信号时，发光状态采集装置201保持关闭，能够节省终端的耗电量。

进一步地，处理器202可以根据发光装置信息确定接收所述光信号的发光装置及解码顺序，然后获取所述发光装置信息对应的所述路由器100上确定的发光装置发送的所述光信号，然后根据解码顺序对所述光信号进行解码。
需要说明的，发光状态采集装置201在开启后，才开始采集前导光信号，在采集到前导光信号后，才开始采集所述光信号。
