在本发明的描述中，如果有描述到第一、第二、第三、第四只是用于区分技术特征为目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量或者隐含指明所指示的技术特征的先后关系。
本发明的描述中，除非另有明确的限定，设置、安装、连接等词语应做广义理解，所属技术领域技术人员可以结合技术方案的具体内容合理确定上述词语在本发明中的具体含义。
目前，多联机系统中的通讯网络主要为有线通讯，外机和内机通过一套物理线缆搭建通讯信道，线控器与内机之间另外通过单独的物理线缆进行通讯，即外机只和内机进行通讯，线控器也只和内机进行通讯，而在智能楼宇或智能家居系统中，线控器之间不可避免地需要进行通讯，则需要经过内机转发，通讯效率低、时效差且存在更高的丢包风险。
基于此，本发明实施例提供一种提供一种多联机系统和多联机系统的通讯方法，能够使得线控器之间直接进行通讯，提高通讯效率，且降低丢包风险。
下面结合附图，对本发明实施例作进一步阐述。
参照图1和图2，本发明的实施例提供一种多联机系统，该多联机系统包括主机、从机、线控器和载波总线。本发明中F 1为第一载波频率，F 2为第二载波频率；图2中Ra为第二选频电阻，Rb为第一选频电阻，MCU(Microcontroller Unit)为微控制单元。
在本实施例提供的多联机系统中，载波总线用于传输通讯信号，也可以用于给主机、从机和线控器供电；主机设置有第一通讯接口芯片，来自载波总线的第一载波频率的通讯信号可以被主机通过第一通讯接口芯片接收，主机也可以发送第一载波频率的通讯信号到载波总线上；从机设置有第二通讯接口芯片，从机可以通过第二通讯接口芯片向载波总线发送第一载波频率的通讯信号或者接收来自载波总线的第一载波频率的通讯信号，主机与从机之间能够在载波总线上搭建第一载波频率的通讯信道，从而进行通讯；线控器设置有第三通讯接口芯片，线控器可以通过第三通讯接口芯片向载波总线发送第一载波频率的通讯信号或者接收来自载波总线的第一载波频率的通讯信号，线控器与从机之间能够在载波总线上搭建第一载波频率的通讯信号，从而进行通讯；线控器还设置有第四通讯接口芯片，线控器可以通过第四通讯接口芯片向载波总线发送第二载波频率的通讯信号或者接收来自载波总线的第二载波频率的通讯信号；在本实施例的多联机系统中，线控器可以与从机在载波总线上建立第一载波频率的通讯信道，从机与主机可以在载波总线上建立第一载波频率的通讯信道，而线控器与线控器之间能够在载波总线上搭建第二载波频率的通讯信道，从而使得线控器之间可以直接进行通讯，降低了丢包率，提高了线控器之间的通讯效率，从而提高了多联机系统的通讯效率。
需要说明的是，在该多联机系统中，主机指外机，从机主要指内机，从机也包括新风机等其他非外机设备，该多联机系统可以有一台主机和多台从机，此时多联机系统即为一拖多系统，比如一台主机搭配四台从机，也可以有多台主机和多台从机，比如两台主机搭配六台从机，本实施例不对主机的数量作具体限定，主机的数量可以根据实际需要设置，本实施例也不对从机的数量作具体限定，从机的数量可以根据实际需要设置。
还需要说明的是，本实施例中通讯信号的传输采用差分传输方式，即一个通讯接口芯片通过两根差分信号传输线接入载波总线，在这两根线上都传输信号，这两根线上的信号振幅相同，相位相反，在这两根线上的传输的信号就是差分信号，信号接收端可以通过比较这两个电压的差值来判断发送端发送的逻辑状态。差分传输可以有效地提高信号传输的抗干扰能力，因为一个干扰源几乎相同程度地影响差分信号对的每一端，而电压差异决定信号值，因此可以忽视在两个导体上出现的任何同样干扰，其中差分信号传输线可以采用双绞线。
还需要说明的是，本实施例可以采用RS485电源载波通讯方案，接口芯片选用TI THVD8000，但不限于该接口芯片，也可以采用其他方案，只要能够区分不同频段的通讯信号，能够实现线控器与线控器、线控器与从机、从机与主机在同一载波总线上建立通讯信道即可。
可以理解的是，主机、从机和线控器都设置有微控制单元，微控制单元可以发出信令，也可以解析并执行来自其他部件的信令，从而使得多联机系统可以正常通讯，多联机系统的功能可以正常运行。
本领域技术人员应当理解的是，集控器可以同时控制多台内机，在本实施例中，也可以使用线控器或者部分线控器替换为集控器，通过集控器控制内机，集控器同样设置有第三通讯接口和第四通讯接口，并接入载波总线，使得集控器和集控器之间或者集控器与线控器之间直接进行通讯，达到同样的效果，即提高通讯效率，降低丢包率。
参照图2，在一些实施例中，第一通讯接口芯片、第二通讯接口和第三通讯接口均连接有第一选频电阻，第一选频电阻可以使得第一通讯接口、第二通讯接口和第三通讯接口的选频为第一载波频率，从而使得第一通讯接口、第二通讯接口和第三通讯接口能够发送或者接收第一载波频率的通讯信号，第四通讯接口芯片连接有第二选频电阻，第二选频电阻可以使得第四通讯接口的选频为第二载波频率，从而使得第四通讯接口能够发送或者接收第二载波频率的通讯信号。
参照图2，在一些实施例中，第一通讯接口芯片、第二通讯接口芯片、第三通讯接口芯片和第四通讯接口芯片均通过电容与载波总线连接，使得主机、从机和线控器可以将通 讯信号通过电容耦合到载波总线上，从而在载波总线上传输通讯信号。
参照图2和图3，本发明实施例还提供一种多联机系统的通讯方法，该多联机系统包括主机、从机、线控器和载波总线，其中，载波总线用于传输通讯信号，主机设置有第一通讯接口芯片，主机可以通过第一通讯接口芯片向载波总线发送第一载波频率的通讯信号或者接收来自载波总线的第一载波频率的通讯信号；从机设置有第二通讯接口芯片，从机可以通过第二通讯接口芯片向载波总线发送第一载波频率的通讯信号或者接收来自载波总线的第一载波频率的通讯信号，主机与从机之间能够在载波总线上搭建第一载波频率的通讯信道，从而进行两者间的通讯；线控器设置有第三通讯接口芯片，线控器可以通过第三通讯接口芯片向载波总线发送第一载波频率的通讯信号或者接收来自载波总线的第一载波频率的通讯信号，线控器与从机之间能够在载波总线上搭建第一载波频率的通讯信号，从而进行通讯；线控器还设置有第四通讯接口芯片，线控器可以通过第四通讯接口芯片向载波总线发送第二载波频率的通讯信号或者接收来自载波总线的第二载波频率的通讯信号，即线控器与线控器之间能够在载波总线上搭建第二载波频率的通讯信道，从而直接进行通讯。在一些多联机系统中，比如智能家居系统，线控器之间不可避免地需要互相交流信息，依照本实施例提供的多联机系统的通讯方法，线控器与线控器进行通讯可以不经过内机转发，而是直接通过第四通讯接口进行通讯，不仅有效地降低了丢包率，同时也提高了通讯效率，减少了无用信息在多联机系统中的载波总线上的传输。
如图3所示，该多联机系统的通讯方法包括但不限于步骤S100。
步骤S100，将一个线控器的第一控制信号以第二载波频率发送至另一个线控器，第一控制信号包括用于使另一个线控器执行相应操作的第一信令和另一个线控器的第一地址信息。
在一实施例中，多联机系统中的一个线控器将第一控制信号通过载波总线发送给另一个线控器，第一控制信号的频率为第二载波频率，第一控制信号包括第一信令和第一地址信息，其中第一信令用于使另一个线控器执行相应的操作，第一地址信息是另一个线控器的地址信息，容易理解的是，第一控制信号的目的地址是另一个线控器，即目标线控器，第一控制信号携带有目标线控器的第一地址信息，线控器可以根据第一地址信息，将第一控制信号发送至另一个线控器。
需要说明的是，可以用集控器代替线控器或者部分线控器，多联机系统还可以有多个集控器，在集控器与集控器之间和/或集控器与线控器之间建立第二载波频率的通讯信道，可以使得集控器与集控器直接进行通讯，集控器与线控器直接进行通讯，提高通讯效率，降低丢包率。对于包括集控器的多联机系统，本实施例提供的通讯方法依然适用，且能够 达到相似的有益效果。
本领域技术人员可以理解的是，为了使得线控器与线控器之间的通讯不受影响，即不会被线控器与内机之间和内机与外机之间的通讯干扰，第一载波频率与第二载波频率之间应当具有一定的间隔，因为两个载波频率过于相近会互相干扰，本实施例中第一载波频率与第二载波频率的间隔大于500KHz，但本实施例不对间隔的频率大小作具体限制，只要能够保证第一载波频率与第二载波频率不互相干涉，第一载波频率的通讯信号和第二载波频率的通讯信号能够同时在载波总线上传输即可。
具体地，参照图2和图4，本发明实施例提供一种多联机系统的通讯方法，在该多联机系统中，第四通讯接口芯片连接有第二选频电阻，第二选频电阻可以将第四通讯接口芯片的选频调整为第二载波频率，以使第四通讯接口芯片可以发送或者接收第二载波频率的通讯信号。
如图4所示，图4是图3中步骤S100的子步骤流程图，步骤S100包括但不限于步骤S110和步骤S120。
步骤S110，一个线控器通过第四通讯接口芯片，将第一控制信号的频率调制为第二载波频率。
步骤S120，根据第一控制信号中的第一地址信息，将第一控制信号发送至另一个线控器。
在一实施例中，第二选频电阻连接于线控器的第四通讯接口芯片，可以通过第二选频电阻，将第四通讯接口芯片的选频调整为第二载波频率，从而使得线控器可以通过第四接口芯片发送或者接收第二载波频率的通讯信号，具体地，一个线控器可以通过连接有第二选频电阻的第四通讯接口芯片，将第一控制信号的频率调制为第二载波频率，随后可以根据第一控制信号中的第一地址信息，通过载波总线上的第二载波频率的通讯信道将第一控制信号发送至另一个线控器，其中第一地址信息即目标线控器的地址信息，目标线控器接收到第一控制信号，可以通过第四通讯芯片解调第一控制信号，从而完成线控器之间的直接通讯，提高通讯效率，有效降低丢包率，目标线控器具有控制处理器，可以解析并执行接收到的第一信令，根据实际需要，线控器可以向内机发送信令，从而使得多联机系统正常运行。
参照图5，本发明的实施例提供一种多联机系统的通讯方法，该方法还包括步骤S200。
步骤S200，将线控器的第二控制信号以第一载波频率发送至从机，第二控制信号包括使该从机执行相应操作的第二信令和该从机的第二地址信息。
在一实施例中，基于上述多联机系统，线控器与线控器之间能够建立第二载波频率的 通讯信道，而线控器与从机之间可以建立第一载波频率的通讯信道，线控器通过该通讯信道发送第一载波频率的第二控制信号至从机。第二控制信号包括第二信令和第二地址信息，第二信令用于使从机执行相应的操作，第二地址信息是目标从机的地址信息，即第二控制信息携带有从机的地址信息，从而可以根据第二地址信息，将第二控制信息发送至目标从机，第一载波频率的第二控制信号可以与第二载波频率的通讯信号同时在载波总线上传输，提高通讯效率。
需要说明的是，第一载波频率的通讯信号与第二载波频率的通讯信号可以同时在载波总线上传输，为了保证第一载波频率与第二载波频率之间不互相干涉，第一载波频率与第二载波频率的间隔应当大于500KHz，本领域技术人员应当理解的是，只要两个载频的间隔能够保证第一载波频率与第二载波频率不互相干涉，都在本实施例的保护范围内。
