基于上述情况，本发明提出一种空调器的内外机配对故障定位方法、内机主控模块、空调器和计算机可读存储介质，能够快速定位配对故障的原因，从而提高空调器的维修效率，优化用户的使用体验。
下面结合附图，对本发明实施例作进一步阐述。
如图1所示，图1是本发明一个实施例提供的用于执行空调器的内外机配对故障定位方法的内机主控模块100的示意图。本发明实施例的内机主控模块100包括一个或多个处理器110和存储器120，图1中以一个处理器110及一个存储器120为例。
处理器110和存储器120可以通过总线或者其他方式连接，图1中以通过总线连接为例。
存储器120作为一种非暂态计算机可读存储介质，可用于存储非暂态软件程序以及非暂态性计算机可执行程序。此外，存储器120可以包括高速随机存取存储器120，还可以包括非暂态存储器120，例如至少一个磁盘存储器120件、闪存器件、或其他非暂态固态存储器120件。在一些实施方式中，存储器120可选包括相对于处理器110远程设置的存储器120，这些远程存储器120可以通过网络连接至该控制器100。上述网络的实例包括但不限于互联 网、企业内部网、局域网、移动通信网及其组合。

在图1所示的内机主控模块100中，处理器110可以用于调用存储器120中储存的内机主控模块100的控制程序，从而实现空调器的内外机配对故障定位方法。
此外，如图2所示，图2是本发明一个实施例提供的空调器的硬件连接示意图。具体地，本发明实施例的空调器的内外机配对故障定位方法，空调器包括连接电力线400网络的内机和外机。其中，内机包括内机主控模块100和分别与内机主控模块100和电力线400网络连接的中央协调器模块；外机包括外机主控模块500和分别与外机主控模块500和电力线400网络连接的站点模块。
需要说明的是，中央协调器模块以下用CCO模块200来进行说明，站点模块以下用STA模块300来进行说明。
基于上述内机主控模块100的硬件结构，提出本发明的空调器的内外机配对故障定位方法的各个实施例。
参照图3，本发明实施例的空调器的内外机配对故障定位方法，应用于内机主控模块100，该方法具体包括但不限于以下步骤S100、步骤S200和步骤S300。
步骤S100：接收配对启动指令；
需要说明的是，该配对启动指令可以由用户控制生成，也可以由内机主控模块100定时自动生成，本实施例并不对其做限制。
步骤S200：基于配对启动指令，生成配对指令并将配对指令发送至目标模块；
需要说明的是，目标模块包括如下组合之一：CCO模块200；CCO模块200和STA模块300；CCO模块200、STA模块300和外机主控模块500。
需要说明的是，该配对指令通过配对内机主控模块100和外机主控模块500，从而配对同一冷媒系统中的外机和内机。
步骤S300：根据目标模块的反馈状态，确定空调器的故障位置；
需要说明的是，由于CCO模块200分别与内机主控模块100和电力线400连接、STA模块300分别与外机主控模块500和电力线400连接，因此，内机主控模块100通过CCO模块200的反馈状态即可判断内机主控模块100和CCO模块200之间是否存在故障，并通过STA模块300的反馈状态即可判断CCO模块200和STA模块300之间是否存在故障，还通过外机主控模块500的反馈状态即可判断STA模块300和外机主控模块500之间是否存在故障。
可以理解的是，根据本发明实施例提供的技术方案，内机主控模块100接收配对启动指 令后，能够基于配对启动指令生成配对指令并将配对指令发送至目标模块，然后根据目标模块的反馈状态，确定空调器的故障位置。由于CCO模块200分别与内机主控模块100和电力线400连接、STA模块300分别与外机主控模块500和电力线400连接，因此，内机主控模块100通过CCO模块200的反馈状态即可判断内机主控模块100和CCO模块200之间是否存在故障，并通过STA模块300的反馈状态即可判断CCO模块200和STA模块300之间是否存在故障，还通过外机主控模块500的反馈状态即可判断STA模块300和外机主控模块500之间是否存在故障。因此，通过本发明实施例的技术方案，能够快速定位配对故障的原因，从而提高空调器的维修效率，优化用户的使用体验。
参照图4，在一些实施例中，目标模块包括CCO模块200；
关于上述步骤S200，具体包括但不限于以下步骤S210。
步骤S210：生成配对请求指令并将配对请求指令发送至CCO模块200；
对应地，关于上述步骤S300，具体包括但不限于以下步骤S310。
步骤S310：当没有接收到来自CCO模块200基于配对请求指令的第一反馈信号，确定内机主控模块100与CCO模块200之间存在故障。
具体地，内机主控模块100接收到配对启动指令后，生成配对请求指令，然后将配对请求指令发送至CCO模块200，当内机主控模块100没有接收到来自CCO模块200的第一反馈信号，则表示发生内机和外机的配对故障，并可确定内机主控模块100与CCO模块200之间存在故障，从而快速定位空调器的内外机配对故障的原因，提高工作人员的检修效率。
可以理解的是，当内机主控模块100没有接收到来自CCO模块200的第一反馈信号时，可重新发送配对请求指令至CCO模块200。若重复发送超过第一预设次数，且内机主控模块100仍没有接收到第一反馈信号，则判断内机主控模块100与CCO模块200之间存在故障。需要说明的是，第一预设次数可以为N次，本实施例并不对其做限制。
参照图5，在一些实施例中，目标模块还包括STA模块300；
关于上述步骤S200，具体包括但不限于以下步骤S220。

步骤S320：当没有接收到来自CCO模块200基于查询配对状态指令的第二反馈信号，确定内机主控模块100与CCO模块200之间存在故障。
具体地，内机主控模块100接收到配对启动指令后，生成配对请求指令，然后将配对请求指令发送至CCO模块200，当内机主控模块100接收到来自CCO模块200的第一反馈信号， 则表示内机主控模块100与CCO模块200之间此时未存在故障。然后内机主控模块100生成查询配对状态指令并通过CCO模块200发送至STA模块300，当内机主控模块100没有接收到来自CCO模块200的第二反馈信号，则表示发生内机和外机的配对故障，并可确定内机主控模块100与CCO模块200之间此时存在故障。需要说明的是，由于内机主控模块100生成查询配对状态指令并通过CCO模块200发送至STA模块300期间，需要耗费约1～2分钟的时间，因此，若此时发生内机和外机的配对故障，原因则可能是内机主控模块100与CCO模块200之间存在故障，而不仅是CCO模块200与STA模块300之间存在故障。因此，通过判断第二反馈信号，能够更加快速、准确地速定位空调器的内外机配对故障的原因。
可以理解的是，当内机主控模块100没有接收到来自CCO模块200基于查询配对状态指令的第二反馈信号时，可继续等待并开始计时。若达到预设时间，且内机主控模块100仍没有接收到第二反馈信号，则判断内机主控模块100与CCO模块200之间存在故障。需要说明的是，预设时间可以为5分钟、10分钟等，本实施例并不对其做限制。
参照图6，在一些实施例中，目标模块还包括STA模块300；
关于上述步骤S200，具体包括但不限于以下步骤S230。

步骤S330：当接收到来自CCO模块200的配对失败指令，确定CCO模块200与STA模块300之间存在故障。
具体地，内机主控模块100接收到配对启动指令后，生成配对请求指令，然后将配对请求指令发送至CCO模块200，当内机主控模块100接收到来自CCO模块200的第一反馈信号，则表示内机主控模块100与CCO模块200之间此时未存在故障。然后，当内机主控模块100接收到来自CCO模块200的配对失败指令，则可确定内机主控模块100与CCO模块200之间未存在故障，同时，可确定发生内机和外机的配对故障，并可确定CCO模块200与STA模块300之间存在故障。
参照图7，在一些实施例中，目标模块还包括外机主控模块500；
关于上述步骤S200，具体包括但不限于以下步骤S240。

对应地，关于上述步骤S300，具体包括但不限于以下步骤S340。
步骤S340：当没有接收到来自外机主控模块500基于配对测试指令的第三反馈信号，确 定STA模块300与外机主控模块500之间存在故障。
具体地，内机主控模块100生成查询配对状态指令并通过CCO模块200发送至STA模块300，当内机主控模块100接收到来自CCO模块200的第二反馈信号，即表示内机主控模块100与CCO模块200之间未存在故障。之后，内机主控模块100生成配对测试指令并将配对测试指令通过CCO模块200和STA模块300发送至外机主控模块500。如此，当内机主控模块100没有接收到来自外机主控模块500的第三反馈信号，即表示发生内机和外机的配对故障，则可确定STA模块300与外机主控模块500之间存在故障。
可以理解的是，当内机主控模块100没有接收到来自外机主控模块500的第三反馈信号时，可重新发送配对测试指令至外机主控模块500。若重复发送超过第二预设次数，且内机主控模块100仍没有接收到第三反馈信号，则判断STA模块300与外机主控模块500之间存在故障。需要说明的是，第二预设次数可以为N次，本实施例并不对其做限制。
参照图8，在一些实施例中，关于上述步骤S300，具体包括但不限于以下步骤S350。
步骤S350：当接收到来自外机主控模块500的配对测试成功指令，确定内机主控模块100和外机主控模块500配对成功。
具体地，内机主控模块100生成配对测试指令并通过CCO模块200和STA模块300发送至外机主控模块500，当接收到来自外机主控模块500的第三反馈信号，则可判断STA模块300与外机主控模块500之间未存在故障。然后，当内机主控模块100接收到来自外机主控模块500的配对测试成功指令，则可确定内机主控模块100和外机主控模块500配对成功，即同一冷媒系统的内机和外机配对成功。
参照图9，在一些实施例中，内机还包括室内显示模块600，该空调器的内外机配对故障定位方法具体还包括但不限于以下步骤S400。
步骤S400：根据目标模块的反馈状态，确定空调器的配对状态，并将配对状态发送至室内显示模块600。
可以理解的是，内机主控模块100接收到配对启动指令后，将空调器的配对状态调整为配对中，并发送该配对状态至室内显示模块600，从而能够方便用户了解空调器的配对状态。
具体地，内机主控模块100能够根据CCO模块200的反馈状态确定内机主控模块100和CCO模块200之间是否存在故障，并能够根据STA模块300的反馈状态确定CCO模块200和STA模块300之间是否存在故障，还能够根据外机主控模块500的反馈状态确定STA模块300和外机主控模块500之间是否存在故障。若存在故障，则将空调器的配对状态调整为配对失败，并将该配对状态发送至室内显示模块600。若未存在故障，且内机主控模块100接收到来自外机主控模块500的配对测试成功指令，则将空调器的配对状态调整为配对成功，并发 送该配对状态至室内显示模块600。
需要说明的是，室内显示模块600可以为内机上的显示屏，还可以为用于将配对状态发送至特定电子设备的通信模块，本实施例并不对其做限制。
在一些实施例中，内机还与遥控器700通信，配对启动指令由遥控器700生成。
可以理解的是，用户可以使用遥控器700生成配对启动指令，以控制内机主控模块100执行配对操作，从而方便用户的使用。
需要说明的是，配对启动指令可以直接由遥控器700生成，还可以由遥控器700发送红外遥控信号至室内显示模块600中由室内显示模块600生成，本实施例并不对其做限制。
基于本发明各个实施例的空调器的内外机配对故障定位方法，下面提出该空调器的内外机配对故障定位方法的整体实施例。
如图10所示，图10是本发明一个实施例提供的空调器的内外机配对故障定位方法的整体流程图。
在一些实施例中，空调器包括与内机通信的遥控器700、连接电力线400网络的内机和外机。具体地，内机包括内机主控模块100、室内显示模块600和分别与内机主控模块100和电力线400网络连接的CCO模块200，外机包括外机主控模块500和分别与外机主控模块500和电力线400网络连接的STA模块300。
需要说明的是，CCO模块200为内机PLC模块，STA模块300为外机PLC模块，PA表示空调器的配对状态为配对中，C1表示空调器的配对状态为配对失败且CCO模块200和STA模块300之间存在故障，C2表示空调器的配对状态为配对失败且内机主控模块100和CCO模块200之间存在故障，C3表示空调器的配对状态为配对失败且STA模块300和外机主控模块500之间存在故障，CS表示空调器的配对状态为配对成功。
首先，室内显示模块600接收到来自遥控器700的配对启动指令，然后显示PA标识，并将配对启动配对指令发送至内机主控模块100。
然后，当内机主控模块100接收到配对指令，内机主控模块100则生成配对请求指令并延时1s发送该配对请求指令至CCO模块200，同时，室内显示模块600保持显示PA标识。若内机主控模块100没有收到来自CCO模块200基于配对请求指令的第一反馈信号，则重复发送配对请求指令至CCO模块200。若超过第一预设次数，仍未收到来自CCO模块200基于配对请求指令的第一反馈信号，则判断配对失败，并控制室内显示模块600显示C2标识。此外，若内机主控模块100接收到来自CCO模块200基于配对请求指令的第一反馈信号，则判断此时内机主控模块100和CCO模块200之间未存在故障，并控制室内显示模块600显示PA标识。
之后，内机主控模块100生成查询配对指令，然后通过CCO模块200发送至STA模块300并开始计时。若内机主控模块100预设时间内没有收到来自CCO模块200基于查询配对指令的第二反馈信号，则判断配对失败，并控制室内显示模块600显示C2标识。若内机主控模块100接收到来自STA模块300的配对失败指令，则判断配对失败，并控制室内显示模块600显示C1标识。此外，若内机主控模块100没有接收到来自STA模块300的配对失败指令，则判断CCO模块200和STA模块300之间未存在故障，并控制室内显示模块600显示PA标识。
最后，内机主控模块100生成配对测试指令并通过CCO模块200和STA模块300发送至外机主控模块500。若内机主控模块100收到来自外机主控模块500基于配对测试指令的第三反馈信号，则重复发送配对测试指令至外机主控模块500。若超过第二预设次数，仍未收到来自外机主控模块500基于配对测试指令的第三反馈信号，则判断配对失败，并控制室内显示模块600显示C3标识。此外，若内机主控模块100接收到来自外机主控模块500的配对测试成功指令，则判断配对成功，并控制室内显示模块600显示CS标识。
通过本发明实施例的技术方案，内机主控模块100接收配对启动指令后，能够基于配对启动指令生成配对指令并将配对指令发送至目标模块，然后根据目标模块的反馈状态，确定空调器的故障位置，从而能够快速定位配对故障的原因，从而提高空调器的维修效率，优化用户的使用体验。
基于上述的空调器的内外机配对故障定位方法，下面分别提出本发明的内机主控模块100、空调器和计算机可读存储介质的各个实施例。
另外，本发明的一个实施例提供了一种内机主控模块100，该内机主控模块100包括：存储器120、处理器110及存储在存储器120上并可在处理器110上运行的计算机程序。
处理器110和存储器120可以通过总线或者其他方式连接。
需要说明的是，本实施例中的控制器，可以应用于如图1所示实施例中的系统架构平台，本实施例中的控制器，能够构成图1所示实施例中的系统架构平台的一部分，两者属于相同的发明构思，因此两者具有相同的实现原理以及有益效果，此处不再详述。

此外，本发明的一个实施例还提供了一种空调器，该空调器包括上述实施例的内机主控模块100。
另外，值得注意的是，由于本发明实施例的空调器包括有上述实施例的内机主控模块100，而上述实施例的内机主控模块100能够执行上述任一实施例的空调器的内外机配对故障定位 方法，因此，本发明实施例的空调器的具体实施方式和技术效果，可以参照上述任一实施例的空调器的内外机配对故障定位方法的控制方法的具体实施方式和技术效果。
此外，本发明的一个实施例还提供了一种计算机可读存储介质，该计算机可读存储介质存储有计算机可执行指令，计算机可执行指令用于执行上述的空调器的内外机配对故障定位方法。示例性地，执行以上描述的图3至图9中的方法步骤。
本领域普通技术人员可以理解，上文中所公开方法中的全部或某些步骤、系统可以被实施为软件、固件、硬件及其适当的组合。某些物理组件或所有物理组件可以被实施为由处理器110，如中央处理器110、数字信号处理器110或微处理器110执行的软件，或者被实施为硬件，或者被实施为集成电路，如专用集成电路。这样的软件可以分布在计算机可读介质上，计算机可读介质可以包括计算机存储介质(或非暂时性介质)和通信介质(或暂时性介质)。如本领域普通技术人员公知的，术语计算机存储介质包括在用于存储信息(诸如计算机可读指令、数据结构、程序模块或其他数据)的任何方法或技术中实施的易失性和非易失性、可移除和不可移除介质。计算机存储介质包括但不限于RAM、ROM、EEPROM、闪存或其他存储器120技术、CD-ROM、数字多功能盘(DVD)或其他光盘存储、磁盒、磁带、磁盘存储或其他磁存储装置、或者可以用于存储期望的信息并且可以被计算机访问的任何其他的介质。此外，本领域普通技术人员公知的是，通信介质通常包括计算机可读指令、数据结构、程序模块或者诸如载波或其他传输机制之类的调制数据信号中的其他数据，并且可包括任何信息递送介质。
以上是对本发明的较佳实施进行了具体说明，但本发明并不局限于上述实施方式，熟悉本领域的技术人员在不违背本发明精神的共享条件下还可作出种种等同的变形或替换，这些等同的变形或替换均包括在本发明权利要求所限定的范围内。
