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。
本发明提供一种基于声波的遥控控制方法。
参照图1所示，为本发明基于声波的遥控控制方法第一实施例的流程图。
在第一实施例中，该基于声波的遥控控制方法包括：
步骤S10，被控终端实时输出预设频率的超声波以供遥控装置接收并检测。
现有的一些如电视机、空调等家电一般采用遥控控制的方式进行功能调节，在本实施例中，可以在电视机、空调等被控终端上设置超声波输出装置，同时在遥控装置上设置超声波检测装置，被控终端实时地输出预设频率的超声波以供遥控装置接收并检测，可以是只要该被控终端启动后，就开始输出预设频率的超声波，也可以是通过被控终端或者遥控装置触发了声波控制模式开启的指令后，开始输出预设频率的超声波。
频率大于人耳的听觉上限20KHz的声波为超声波，因此本实施例优选地以30KHz作为预设频率，在其他的实施例中，可以选择其他的频率值作为预设频率，只要大于20KHz即可。
步骤S20，所述被控终端接收到遥控装置发送的遥控指令时，从所述遥控指令中获取所述遥控装置检测到的所述超声波的频率值。
被控终端实时地发送超声波，因此遥控装置在能够接收到超声波的范围内时，会实时地检测到超声波并获取到超声波的频率，遥控装置在检测到超声波时，实时地将获取到的频率发送至被控终端，由于不同的遥控装置在进行遥控控制时采用不同的编码格式，因此，遥控装置在发送频率时，可以在固有的编码中加入表示发送的频率值的频率码进行发送，在其他实施例中，也可以采用其他的发送频率值的方法，例如，直接将频率值进行编码发送。
被控终端在接收到遥控装置发送的遥控指令时，从该指令中获取频率码，进而获取遥控装置返回的频率值，对于直接将频率值进行编码发送的方式，可以对获取到的码值进行解码获取频率值。
步骤S30，所述被控终端将所述频率值和所述预设频率进行比较，并根据比较结果产生相应的控制指令。
由多普勒效应可知，当观测者与波源相对运动时，观测者接收到的频率会相对于波源发出的波的频率有变化，当观测者向波源接近时，接收到的频率会变高，相反地，当观测者远离波源时，接收到的频率会变低。
因此，当用户想要调节被控终端时，只需要控制遥控装置相对于被控终端发生相对位移，即人手拿着遥控装置相对被控终端进行运动，遥控装置接收到的超声波的频率会大于或者小于上述预设频率，当遥控装置相对于被控终端没有相对移动时，接收到的频率等于预设频率。
在本实施例中，将获取到频率值与预设频率进行比较，被控终端根据比较结果产生相应的控制指令，可以是根据频率值与预设频率的大小关系，也可以获取频率值与预设频率的差值，也可以是根据差值的大小产生相应的控制指令，需要说明的是，频率值与预设频率的差值是指从遥控指令中获取到频率值减去预设频率值得到的差值。
基于上述原理，当根据差值的大小产生相应的控制指令时，具体可以多种实施方式，在一实施例中，可以根据接收到的频率值与预设频率的差值大于零或小于零，分别设置两个对应的功能，获取所述频率值与所述预设频率的差值；当所述频率值与所述预设频率的差值大于零时，按照第一预设指令调节被控终端，当所述频率值与所述预设频率的差值小于零时，按照第二预设指令调节被控终端。例如，当检测到的频率与预设频率的差值大于零时，对应频道加的功能，则被控终端响应遥控指令向上切台，当检测到的频率与预设频率的差值小于零时，对应频道减的功能，则被控终端响应遥控指令向下切台。在另一实施例中，为了增强功能调节的准确性，可以设置预设时长作为进一步的判断条件，即在一定时长内检测到的频率值均满足条件时，才进行功能调节。需要说明的是，在其他实施例中，可以根据需要设置多个频率区间，对应不同的控制指令。在其他实施例中，可以进一步地设置多个差值区间，不同差值区间对应不同的控制指令。
本实施例提出的基于声波的遥控控制方法，在声波控制模式下，持续不断的输出一定预设频率的超声波，遥控装置在检测到超声波时，获取超声波的频率并将频率加载至遥控指令中发送至被控终端，用户需要调节被控终端时，可以拿着遥控装置靠近或者远离被控终端，这样被控终端接收到的频率值会与发送的预设频率不相同，被控终端可以根据频率值与预设频率的比较结果进行相应的调节；本发明无需用户对遥控按键进行操作，控制遥控装置相对被控终端靠近或者远离，即可实现对被控终端的调节，解决了现有技术中因为用户按错键而导致无法准确地调节被控终端的问题。
参照图2所示，基于发明基于声波的遥控控制方法的第一实施例提出本发明基于声波的遥控控制方法的第二实施例。在本实施例中，所述方法与第一实施例的区别在于，步骤S10包括以下细化步骤：
步骤S11，所述被控终端实时输出加载有标识信息的预设频率的超声波，以供所述遥控装置在检测到具有所述标识信息的超声波时，检测所述超声波的频率值并将所述频率值加载至所述遥控指令中。
由于现有的其他一些家电可能也具有发送超声波的功能，为了避免其他设备发出的超声波信号的干扰，可以对电视机发出的超声波信号进行加载标识信息，遥控装置只有在检测到具有该标识信息的超声波时，才将该超声波的频率值加载在遥控指令中并进行遥控指令的发送，例如可以将超声波作为载波，将标识信息包含的数据内容加载至超声波中。
进一步地，在步骤S10之前，该基于声波的遥控控制方法还包括：
所述被控终端在接收到所述遥控装置发送的开启声波控制模式的指令时，切换至所述声波控制模式，其中，所述遥控装置在检测到环境亮度低于预设亮度时，向电视端发送所述开启声波控制模式的指令；
所述被控终端在切换至所述声波控制模式时，执行步骤S10。
在本实施例中，当被控终端在接收到遥控装置发送的开启声波控制模式的指令时，切换至声波控制模式，以避免在可以正常进行按键控制时，被控终端仍然在时刻不停地输出超声波，以节省电量。
在遥控装置中设置亮度感应装置，能够实时检测环境亮度，当检测到环境亮度低于预设亮度时，向被控终端发送开启声波控制模式的指令以控制电视端切换至声波控制模式。进一步地，当检测到环境亮度恢复高于预设亮度时，则自动发送指令，控制被控终端退出声波控制模式，停止超声波的输出。
本实施例提出的基于声波的遥控控制方法，在输出的超声波中加载标识信息，以避免其他设备输出的超声波信号的干扰，增强调节的准确性，而且，被控终端可以通过指令自动在声波控制模式与一般模式之间切换，无需手动调节。
基于发明基于声波的遥控控制方法的第一实施例提出本发明基于声波的遥控控制方法的第三实施例。在本实施例中，所述方法与第一实施例的区别在于，步骤S30包括以下细化步骤：
所述被控终端获取所述频率值与所述预设频率的差值；
当在预设时长内获取到的所述频率值与所述预设频率的差值均位于预设区间时，所述被控终端按照所述预设区间对应的调节指令进行相应的调节。
为了增强调节的准确性，避免因为用户的误操作而导致错误调节的情况，增加预设时长作为判断条件。无论用户是否对遥控装置进行了操作，遥控装置都会持续地输出检测到的频率，被控终端会持续地获取到频率值。
所述预设区间可以根据需要调节的功能进行设置两个或者两个以上，不同的区间对应不同的调节指令，以电视机为例，当差值大于0KHz且小于10KHz时，为频道加，当差值大于-10KHz小于0KHz时，为频道减。
可以在被控终端内设置计时装置或者利用被控终端内原有的计时装置，在获取到的所述频率值与所述预设频率的差值大于零时，开始计时，当累计等于或者大于预设时长时，被控终端按照第一预设指令进行调节，如果计时未达到预设时长时，获取到的所述频率值与所述预设频率的差值小于或者等于零，则将计时清零，按照上述过程，在频率值与预设频率的差值达到预设条件且累计时间达到预设时长时，被控终端按照对应的指令调节。
本实施例提出的基于声波的遥控控制方法，为了避免因为用户的误操作而导致错误调节的情况，增加预设时长作为判断条件，增强了调节的准确性。
本发明还提出一种基于声波的遥控控制系统。
参照图3所示，为本发明基于声波的遥控控制系统第一实施例的功能模块示意图。
在该实施例中，该基于声波的遥控控制系统包括：
声波输出模块10，用于实时输出预设频率的超声波以供遥控装置接收并检测。
现有的一些如电视机、空调等家电一般采用遥控控制的方式进行功能调节，在本实施例中，可以在电视机、空调等被控终端上设置超声波输出装置，同时在遥控装置上设置超声波检测装置，声波输出模块10实时地输出预设频率的超声波以供遥控装置接收并检测，可以是只要该被控终端启动后，就开始输出预设频率的超声波，也可以是通过被控终端或者遥控装置触发了声波控制模式开启的指令后，声波输出模块10开始输出预设频率的超声波。
频率大于人耳的听觉上限20KHz的声波为超声波，因此本实施例优选地以30KHz作为预设频率，在其他的实施例中，可以选择其他的频率值作为预设频率，只要大于20KHz即可。
频率获取模块20，用于当接收到遥控装置发送的遥控指令时，从所述遥控指令中获取所述遥控装置检测到的所述超声波的频率值。
被控终端实时地发送超声波，因此遥控装置在能够接收到超声波的范围内时，会实时地检测到超声波并获取到超声波的频率，遥控装置在检测到超声波时，实时地将获取到的频率发送至被控终端，由于不同的遥控装置在进行遥控控制时采用不同的编码格式，因此，遥控装置在发送频率时，可以在固有的编码中加入表示发送的频率值的频率码进行发送，在其他实施例中，也可以采用其他的发送频率值的方式，例如，直接将频率值进行编码发送。
被控终端在接收到遥控装置发送的遥控指令时，频率获取模块20从该指令中获取频率码，进而获取遥控装置返回的频率值，对于直接将频率值进行编码发送的方式，可以对获取到的码值进行解码获取频率值。
功能调节模块30，用于将所述频率值和所述预设频率进行比较，并根据比较结果产生相应的控制指令。
由多普勒效应可知，当观测者与波源相对运动时，观测者接收到的频率会相对于波源发出的波的频率有变化，当观测者向波源接近时，接收到的频率会变高，相反地，当观测者远离波源时，接收到的频率会变低。
因此，当用户想要调节被控终端时，只需要控制遥控装置相对于被控终端发生相对位移，即人手拿着遥控装置相对被控终端进行运动，遥控装置接收到的超声波的频率会大于或者小于上述预设频率，当遥控装置相对于被控终端没有相对移动时，接收到的频率等于预设频率。
在本实施例中，将获取到频率值与预设频率进行比较，功能调节模块30根据比较结果产生相应的控制指令，可以是根据频率值与预设频率的大小关系，也可以获取频率值与预设频率的差值，也可以是根据频率值与预设频率的差值的大小产生相应的控制指令，需要说明的是，本实施例中的频率值与预设频率的差值是指从遥控指令中获取到频率值减去预设频率值得到的差值。
基于上述原理，当根据差值的大小控制被控终端的调节时，具体可以多种实施方式，在一实施例中，功能调节模块30可以包括以下单元：
第一差值获取单元，用于获取所述频率值与所述预设频率的差值；
第一功能调节单元，用于当所述频率值与所述预设频率的差值大于零时，按照第一预设指令进行调节，当所述频率值与所述预设频率的差值小于零时，按照第二预设指令进行调节。
当检测到第一差值获取单元获取到的频率与预设频率的差值大于零时，对应频道加的功能，则第一功能调节单元响应遥控指令向上切台，当检测到的频率与预设频率的差值小于零时，对应频道减的功能，则第一功能调节单元响应遥控指令向下切台。
在另一实施例中，为了增强功能调节的准确性，可以设置预设时长，即在一定时长内检测到的频率值均满足条件时，功能调节模块30才进行功能调节。需要说明的是，在其他实施例中，可以根据需要设置多个频率区间，对应不同的控制指令。在其他实施例中，可以进一步地设置多个差值区间，不同差值区间对应不同的控制指令。
本实施例提出的基于声波的遥控控制系统，在声波控制模式下，持续不断的输出一定预设频率的超声波，遥控装置在检测到超声波时，获取超声波的频率并将频率加载至遥控指令中发送至被控终端，用户需要调节被控终端时，可以拿着遥控装置靠近或者远离被控终端，这样被控终端接收到的频率值会与发送的预设频率不相同，被控终端可以根据频率值与预设频率的比较结果进行相应的调节；本发明无需用户对遥控按键进行操作，控制遥控装置相对被控终端靠近或者远离，即可实现对被控终端的调节，解决了现有技术中因为用户按错键而导致无法准确地调节被控终端的问题。
基于发明基于声波的遥控控制系统的第一实施例提出本发明基于声波的遥控控制系统的第二实施例。在本实施例中，所述装置与第一实施例的区别在于：
声波输出模块10，还用于实时输出加载有标识信息的预设频率的超声波，以供所述遥控装置在检测到具有所述标识信息的超声波时，检测所述超声波的频率值并将所述频率值加载至所述遥控指令中。
由于现有的其他一些家电可能也具有发送超声波的功能，为了避免其他设备发出的超声波信号的干扰，可以对电视机发出的超声波信号进行加载标识信息，遥控装置只有在检测到具有该标识信息的超声波时，才将该超声波的频率值加载在遥控指令中并进行遥控指令的发送，例如可以将超声波作为载波，将标识信息包含的数据内容加载至超声波中。
进一步地，参照图4所示，该基于声波的遥控控制系统还包括：
模式切换模块40，用于在接收到所述遥控装置发送的开启声波控制模式的指令时，切换至所述声波控制模式，其中，所述遥控装置在检测到环境亮度低于预设亮度时，向电视端发送所述开启声波控制模式的指令；
触发模块50，该触发模块50用于在切换至所述声波控制模式时，触发声波输出模块10实时输出预设频率的超声波以供遥控装置接收并检测。
在本实施例中，当被控终端在接收到遥控装置发送的开启声波控制模式的指令时，模式切换模块40控制被控终端切换至声波控制模式，以避免在可以正常进行按键控制时，被控终端仍然在时刻不停地输出超声波，以节省电量。
在遥控装置中设置亮度感应装置，能够实时检测环境亮度，当检测到环境亮度低于预设亮度时，向被控终端发送开启声波控制模式的指令以控制电视端切换至声波控制模式。进一步地，当检测到环境亮度恢复高于预设亮度时，则自动发送指令，控制被控终端退出声波控制模式，停止超声波的输出。
本实施例提出的基于声波的遥控控制系统，在输出的超声波中加载标识信息，以避免其他设备输出的超声波信号的干扰，增强调节的准确性，而且，被控终端可以通过指令自动在声波控制模式与一般模式之间切换，无需手动调节。
基于发明基于声波的遥控控制系统的第一实施例提出本发明基于声波的遥控控制系统的第三实施例。在本实施例中，所述装置与第一实施例的区别在于：
功能调节模块30包括以下细化单元：
第二差值获取单元，用于获取所述频率值与所述预设频率的差值；
第二功能调节单元，用于当在预设时长内获取到的所述频率值与所述预设频率的差值均位于预设区间时，按照所述预设区间对应的调节指令进行相应的调节。
为了增强调节的准确性，避免因为用户的误操作而导致错误调节的情况，增加预设时长作为判断条件。无论用户是否对遥控装置进行了操作，遥控装置都会持续地输出检测到的频率，被控终端会持续地获取到频率值。
所述预设区间可以根据需要调节的功能进行设置两个或者两个以上，不同的区间对应不同的调节指令，以电视机为例，当差值大于0KHz且小于10KHz时，为频道加，当差值大于-10KHz小于0KHz时，为频道减。
可以在被控终端内设置计时装置或者利用被控终端内原有的计时装置，在第二差值获取单元获取到的所述频率值与所述预设频率的差值大于零时，开始计时，当累计等于或者大于预设时长时，第二功能调节单元按照第一预设指令进行调节被控终端，如果计时未达到预设时长时，获取到的所述频率值与所述预设频率的差值小于或者等于零，则将计时清零，按照上述过程，在频率值与预设频率的差值达到预设条件且累计时间达到预设时长时，第二功能调节单元按照对应的指令调节被控终端。
本实施例提出的基于声波的遥控控制系统，为了避免因为用户的误操作而导致错误调节的情况，增加预设时长作为判断条件，增强了调节的准确性。
以上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。
