具体实施方式
下面详细描述本公开的实施例，实施例的示例在附图中示处，其中自始至终相同或类似的元件标号表示相同或类似的元件具有相同或类似的功能的元件，参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制，下面详细描述本公开的实施例。
考虑到采用交流电信号例如24V交流电源通讯，室内机、室外机、温控器之间只能识 别高低电平，并不能获得发送方具体的运行参数，因而不利于改善空调运行状态，能效低。在本公开实施例中，对室内机、室外机和温控器的通信方式进行改进，以实现具体运行参数的传输，进而为空调优化控制策略提供支持，达到及时通信的目的。下面对本公开实施例的空调通信实现来进行描述。
图1是本公开提供的一种空调器通用的通讯方式的示意图。如图1所示，用户操控温控器控制室外机、室内机工作。例如，温控器发出给外机和内机的信号为工频交流电24Vac，该交流信号经过信号检测电路后，室外机识别的仅是高低电平信号。尤其室外机是变频机时，室外机只能通过识别高低电平信号，接收温控器的开启或变比指令进行工作，室外机主控MCU(Microcontroller Unit，微控制单元)只能识别出两种状态，即该交流电通讯方式只能实现单向的开启和关闭控制，如压缩机启动或停止信号、制热时四通阀开启信号以及外机发给内机的除霜信号等。交流电24Vac信号通过电路转换，主控MCU接收到的也只是高低电平信号。
因而，采用上面的交流电通讯方式，导致室外机和室内机之间不能实时通讯，不能掌握系统的运转参数，例如，室外机不知道室内机的环温、内盘温等参数，内室内机不知道室外机的频率、外盘温等参数，空调不能达到最优工作状态，导致能效偏低。
图2是本公开一个实施例的室内机的框图，如图2所示，室内机10包括室内机壳体101、室内主控模块102、室内通信模块103。
其中，室内主控模块102设置在室内机壳体101内，例如，室内主控模块102可以为主控MCU，室内主控模块102用于发送室内机参数，例如室内机参数可以包括室内机的环温、内盘温等参数，一般情况下室内机参数以交流信号的形式发送出去。室内通信模块103与室内主控模块102连接，用于接收到室内机参数，并基于室内机参数产生包含室内机参数的第一高频信号，以及将第一高频信号加载到原始电源通信线上，以发送室内机参数。
例如，室内通信模块103可以由一个专用集成电路及对应的周边电路组成，其中在专用集成电路中可以设置至少一个通讯芯片，室内机的主控MCU发送室内机参数给通讯芯片，通讯芯片产生第一高频信号，并能将第一高频信号加载到原始电源通信线上，随原始电源通信线传递到接收端，从而完成发送室内机参数，从而能够实现由室内机10的内部向室内机10的外部的通信。其中，在实施例中，原始电源通信线可以为目前空调室内机通信使用的交流电信号线例如24V电源通信线，但不仅限于工频交流电压24Vac，在满足电路器件耐压足够、且能够滤掉原始电源信号的要求下，可以设置为任意的交流工作电压范围，例如5V或12V、或20V等。
根据本公开实施例的室内机10，可以在不改变原始通讯方式的基础上，能及时地将室内机参数以在原始电源通信线上加载高频信号的形式实现通信，例如室内机能及时发送环 温、内盘温等参数到原始电源通信线上，可以实现与其他部分的的实时通讯。
在本公开的实施例中，如图2所示，室内机10还包括室内滤波模块104，室内滤波模块104与室内通信模块103连接，其接收端接收到原始电源通信线上的通信信号后，将通信信号后经过室内滤波模块104能够滤除通信信号中的原始电源信号，能够获得包含发送端参数的第二高频信号，其中，发送端可以包括室外机或者温控器等，在实施例中，室内滤波模块104可以包括电容，由电容实现滤波。室内滤波模块104还能够基于第二高频信号解析出发送端参数，并将发送端参数反馈给室内主控模块102，从而能够实现由室内机10的外部向室内机10的内部的通信，实现发送方与接收方的双向通信，并且不只是识别高低电平，可以及时了解发送方具体的运行参数，从而为改进控制策略提供参考。
图3是本公开实施例提供的室外机的框图。
如图3所示，室外机20可以至少包括室外机壳体201、室外主控模块202、室外通信模块203等。其中，室外主控模块202设置在室内机壳体201内，例如，室外主控模块202可以为主控MCU，室外主控模块202用于发送室外机参数，例如室外机参数可以包括室外机20的频率、外盘温等参数，一般情况下室外机参数以交流信号的形式发送出去。室外通信模块203与室外主控模块202连接，用于接收到室外机参数，并基于室外机参数产生包含室外机参数的第三高频信号以及将第三高频信号加载到原始电源通信线上，以发送室内机参数。
例如，室外通信模块203可以由一个专用集成电路及对应的周边电路组成，其中在专用集成电路中可以设置至少一个通讯芯片，室外机20的主控MCU发送室外机参数给通讯芯片，通讯芯片产生第三高频信号，并能将第三高频信号加载到原始电源通信线上随原始电源通信线传递到接收端，从而完成发送室外机参数，从而能够实现由室外机20的内部向室外机20的外部的通信。其中，在实施例中，原始电源通信线可以为目前空调室内机通信使用的交流电信号线例如24V电源通信线，但不仅限于工频交流电压24V，在满足电路器件耐压足够、且能够滤掉原始电源信号的要求下，可以设置为任意的交流工作电压范围，例如5V或12V、或20V等。
根据本公开实施例的室外机20，可以在不改变原始通讯方式的基础上，能及时地将室外机参数以在原始电源通信线上加载高频信号的形式实现通信。由于本公开实施例的室内机10也可以采用在原始电源通信线上加载高频信号的形式实现通信，可以实现室内机20与室外机10共同在原始电源通信线上加载高频信号，实现室外机20与室内机10的实时通讯，例如室内机10能及时发送环温、内盘温等参数到原始电源通信线上并能被室外机20接收，室外机20也能及时发送频率、外盘温等参数到原始电源通信线上并能被室内机10接收，当室外机20有故障时，故障信息也能及时发送出来，使空调工作系统达到最优，提高能效。
在本公开的实施例中，如图3所示，室外机20还包括室内滤波模块204，室外滤波模块204与室外通信模块203连接，其接收端接收到原始电源通信线上的通信信号后，将通信信号后经过室外滤波模块204能够滤除通信信号中的原始电源信号，能够获得包含发送端参数的第四高频信号，其中，发送端可以包括室内机10或者温控器30等。在实施例中，室外滤波模块204可以为电容，通过电容实现滤波以获得发送端参数，从而实现了发送端和接收端的双向通信，并且不只是识别高低电平，可以及时了解具体运行参数，为改善控制策略提供参考。
如果室外机20为变频机时，则室外机20只能通过检测室外系统的参数进行变频工作，接收不到室内机10的一些关键参数，不能充分发挥变频的作用，造成室外机20虽然是变频工作，但能效相对较低。本公开实施例的室外滤波模块204能够基于第四高频信号解析出发送端参数，并将发送端参数反馈给室外主控模块202，从而能够实现由室外机20的外部向室外机20的内部的通信。例如室外变频系统，室外机20不仅可以通过检测室外机参数进行变频工作，同时还可以接收到室内机参数，能充分发挥变频的作用，从而提高能效。
图4是本公开一个实施例的温控器的框图。如图4所示，本公开实施例的温控器30至少可以包括温控器壳体301、温控模块302、温控通信模块303、温控滤波模块304、显示模块305等。其中，温控模块302设置在温控器壳体301内，用户可以通过温控器30的温控模块302发送温控设置参数。温控通信模块303与温控模块302连接，用于接收温控模块302发送的温控设置参数。例如，温控通信模块303可以由一个专用集成电路及对应的周边电路组成，其中在专用集成电路中可以设置至少一个通讯芯片，在发送温控设置参数时，温控器30的主控MCU发送相应的交流信号给通讯芯片，通讯芯片产生第五高频信号，并能将第五高频信号加载到原始电源通信线上，随原始电源通信线传递到接收端，从而完成发送温控设置参数。
根据本公开实施例的温控器30，可以在不改变原始通讯方式的基础上，能及时地将温控器30的温控设置参数以在原始电源通信线上加载高频信号的形式，可以实现与其他部分的实时通讯，使空调工作系统达到最优，提高能效。
在本公开的实施例中，如图4所示，温控器30还可以包括温控滤波模块305，温控滤波模块305与温控通信模块303连接，其接收端接收到原始电源通信线上的通信信号后，将通信信号后经过温控滤波模块305能够滤除通信信号中的原始电源信号，能够获得包含发送端参数的第六高频信号，其中，发送端可以包括室内机的发送端或者室外机的发送端等。温控滤波模块305还能够基于第六高频信号解析出发送端参数，并将发送端参数反馈给温控模块302，从而能够实现由温控器30的外部向温控器30的内部的通信。
根据本公开实施例的温控器30，相对于交流强电载波通讯通信方式，采用在原始电源通信线上加载高频信号的方式进行传输，不用在各部分之间设置交流强电载波通讯电路， 只需要在内室机10、室外机20、或者温控器30中增加相关的通讯电路，电路简单，节省成本，还能实现与其他部分的实时通信，使空调工作系统达到最优，提高能效。
在本公开的实施例中，如图4所示，温控器30还可以包括显示模块306，显示模块306与温控模块302连接，例如，显示模块306可以为温控器30上设置的显示屏或者显示灯或者报警器等，能够用于显示接收到的发送端参数。
在相关技术中，在原始电源通信线上通交流电从而实现信号传递为常见的通信方式，交流电通信方式只能实现单向的开启和关闭控制。温控器发出给外室机和内室机的交流电信号以交流电24V为例，尤其室外机是变频机时，外室机只能接收到温控器的开启或变比指令进行工作，例如，温控器只能单向发送压缩机启动或停止信号或者在制热时发送四通阀开启信号给外室机，主控MCU接收到的也只是高低电平信号，导致各部分之间不能实时通讯。
在本公开实施例中，原始电源通信线上的通信信号既包括交流电信号也包括包含有发送端参数的高频信号，既保留了在原始电源通信线上通交流电的通信方式，室内机10、室外机20和温控器30还能实时接收发送端参数，实现实双向通信，例如当室外机10发生故障时，能将故障信息参数发送出来，被温控器30接收后，将接收到的包括有故障信息参数的高频信号转换成发送端故障信息参数，并可以通过显示模块306显示出来，从而能及时通知到用户。能够实现与内室机10和外室机20之间实时通讯，使系统工作在最优模式，提高能效。
图5是本公开一个实施例的空调器的通讯方式的示意图。
如图5所示，在现有的通讯方案基础上，可以在室内机10、室外机20分别增加通信模块和滤波模块，室内通信模块103和室外通信模块203均可以设置为一个专用集成电路及对应的周边电路。用于基于发送端参数生成包含发送端参数的高频信号以及基于包含发送端参数的高频信号生成发送端参数。其中，例如图5所示，专用集成电路可以包括至少一个通信芯片，本公开实施例的通讯芯片以芯片THVD8000为例，但不仅限于此芯片，包括任何能实现本公开实施例的空调器的通讯方式的芯片。如图5所示，室内滤波模块104和室外滤波模块204均可以设置为至少两个电容，用于滤除通信信号中的原始电源信号。使通信信号在经过接收端电容时通信信号中的原始电源信号被滤掉，只留下高频信号。
如图5所示，室内机10中设置有线性变压器105，用于将交流电调制为原始电源信号电压，以交流电24V为例，室内机10可以通过原始电源通信线给温控器供电，室外机20可以通过原始电源通信线给室内机发送除霜信号，温控器30可以通过原始电源通信线发送控制压缩机信号和控制四通阀信号给室外机20，还可以发送控制室内风机信号。室外机20中设置有Y/B信号检测电路205，用于将24V交流电信号转换成高低电平信号。以室外机20与室内机10的通信过程为例，室外主控模块202的主控MCU发送室外机参数，如 室外机的频率、外盘温等参数给室外通信模块203的通讯芯片，通讯芯片基于室外机参数产生高频信号，加载到原始电源通信线上，原始电源通信线以24V电源通信线为例，原始电源通信线中的通信信号包含有高频信号和原始电源信号，通信信号随24V电源通信线传递到室内机10的室内滤波模块104的接收端。使通信信号在经过室内滤波模块104时通信信号中的原始电源信号被滤掉，只留下高频信号并输送到室内机的室内通信模块的通讯芯片中，通讯芯片可以基于接收到的高频信号生成室外机参数再传递到室内主控模块的主控MCU中。同理，室内机10发送室内机参数给室外机20也可以采用本公开实施例的空调器的通讯方式，能够同时实现发送和接收信号，实现室内机10与室外机20之间在现有的通讯方案基础上加载高频信号实现双向通讯。
再例如，在本公开的实施例中，还可以在温控器30中增加温控器通信模块和温控滤波模块，在图5中省略未画出，其中，温控器通信模块也可以设置为一个专用集成电路及对应的周边电路，用于基于发送端参数生成包含发送端参数的高频信号以及基于包含发送端参数的高频信号生成发送端参数，专用集成电路可以包括至少一个通信芯片，本公开的通讯芯片以芯片THVD8000为例，但不仅限于此芯片，包括任何能实现本公开实施例的空调器的通讯方式的芯片。如果温控器30将温控设置参数在原始电源通信线上加载高频信号的形式发送至接收端，可以实现与其他部分的实时通讯。温控滤波模块均可以设置为包括至少两个电容，用于滤除通信信号中的原始电源信号。使通信信号在经过接收端电容时通信信号中的原始电源信号被滤掉，只留下高频信号。如果室内机或者室外机发生故障时可以基于故障信息产生包含故障信息的高频信号，将高频信号加载在原始电源通信线上传输给温控器，被温控器接收后经过温控滤波模块并能通过温控器中的显示模块及时通知到用户，实现温控器与室内机和室外机之间的实时通信。
图6是本公开一个实施例的空调器的通讯波形转换的示意图。
在本公开的实施例中，能够实现在现有的通讯方案基础上加载高频信号实现空调室内机、室外机以及温控器间的双向通讯。如图6所示，主控MCU只能发出或者识别高低电平信号，主控MCU将空调参数以高低电平信号形式发送给通讯芯片，通讯芯片通过与主控MCU之间的接地电阻进行频率选择，并基于空调参数产生高频信号，然后将包含有空调参数的高频信号在原始电源通信线上，并随原始电源通信线上的通信信号传输到接收端。接收端接收到通信信号后，滤波模块将通信信号中的原始电源信号滤掉，得到包含有空调参数的高频信号，通信芯片基于高频信号得到对应的空调参数，并将空调参数转换成高低电平信号发送到主控MCU中，完成信号的传输与识别。原始电源通信线与交流电源连接，用于交流电的传输。
图7是本公开一个是实施例的控制空调通信的方法的流程图。
本公开实施例的控制空调通信的方法，如图7所示，可以至少包括步骤S101-S106.
S101，接收到主控模块发送的空调参数，其中，空调参数包括室内机参数、室外机参数和温控器设置参数中的至少一种。例如空调参数可以包括室内机的环温、内盘温等参数，或者室外机的频率、外盘温或者故障信息等参数。空调参数由室内机、室外机或者温控器发出并可以被室内机、室外机或者温控器中的通信模块接收。
S102，基于空调参数产生高频信号，其中，高频信号包含空调参数。室内机、室外机或者温控器中的通信模块将接收到的空调参数在内部的通信模块中进行调制产生包含空调参数的高频信号。
S103，将包含空调参数的高频信号加载到原始电源通信线上，以发送空调参数。
本公开实施例的空调通信方法，相对于交流强电载波通讯通信方式，采用在原始电源通信线上加载高频信号的方式进行传输，既能实现室内机与室外机与温控器之间的实时通信，还不用增加交流强电载波通讯电路，节省成本。
S104，接收到原始电源通信线上的通信信号，通信信号包括包含发送端参数的高频信号和原始电源信号。
在本公开的实施例中，可以保留现有技术中在原始电源通信线上通交流电的通信方式，同时增加在原始电源通信线上加载高频信号的通信方式。则原始电源通信线上的通信信号既包括原始电源信号也包括包含发送端参数的高频信号，例如原始电源信号包括温控器给室外机发出的开启或变比指令信号，如压缩机启动或停止信号以及制热时四通阀开启信号等，还可以包括外机发给内机的除霜信号等。在原始电源通信线上加载高频信号，并不影响原始电源信号在各部分之间的传输。
S105，滤除通信信号中的原始电源信号，以获得包含发送端参数的高频信号。原始电源通信线上的通信信号被室内机或者室外机或者温控器内部的滤波模块接收后，滤波模块可以将通信信号中的原始电源信号滤掉，只剩下通信信号中加载的包含空调参数的高频信号。
S106，根据包含空调参数的高频信号解析出发送端参数，并将发送端参数反馈给主控模块。室内机或者室外机或者温控器内部的通信模块包含空调参数的高频信号解析出发送端参数并反馈给主控模块，从而实现各部分之间的实时通信。
根据本公开实施例的控制空调通信的方法，使发送端既能发送原始电源信号，实现由温控器对室外机以及室内机的单向的开启和关闭控制或者是室内机对室外机的交流电通信，也能发送包含空调参数的高频信号，通过各部分对空调参数的发送与接收实现各部分之间的实时通信，并且在原始电源通信线上加载高频信号，不影响两种信号的传输，也不用增加交流强电载波通讯电路，只需要在室内机、室外机分别增加相关通讯电路，且电路简单，节省成本。
总的来说，在本公开实施例中，在现有的通讯方案基础上，在原始电源通信线上加载 高频信号从而实现空调室内机、室外机以及温控器间的双向通讯。只需要在室内机、室外机或者温控器中分别增加一个相关通讯电路，电路简单，成本最优，如果室外机为变机时，不仅能通过检测室外机的参数进行变频工作，还能接收到室内机以及温控器的参数，能充分发挥变频的作用，提高能效。
