具体实施方式
下面将结合附图，对本公开一些实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开所提供的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本公开保护的范围。
除非上下文另有要求，否则，在整个说明书和权利要求书中，术语“包括(comprise)”及其其他形式例如第三人称单数形式“包括(comprises)”和现在分词形式“包括(comprising)”被解释为开放、包含的意思，即为“包含，但不限于”。在说明书的描述中，术语“一个实施例(one embodiment)”、“一些实施例(some embodiments)”、“示例性实施例(exemplary embodiments)”、“示例(example)”、“特定示例(specific example)”或“一些示例(some examples)”等旨在表明与该实施例或示例相关的特定特征、结构、材料或特性包括在本公开的至少一个实施例或示例中。上述术语的示意性表示不一定是指同一实施例或示例。此外，所述的特定特征、结构、材料或特点可以以任何适当方式包括在任何一个或多个实施例或示例中。
以下，术语“第一”、“第二”仅用于描述目的，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。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本公开一些实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
在描述一些实施例时，可能使用了“耦接”和“连接”及其衍伸的表达。术语“连接”应作为广义理解，例如，“连接”可以是固定连接，也可以是可拆卸连接，或成一体；可以是直接连接，也可以是通过中间媒介间接连接。术语“耦接”以表明两个或两个以上部件有直接物理接触或电接触。然而，术语“耦接”或“通信耦合(communicatively coupled)”也可能指两个或两个以上部件彼此间并无直接接触，但仍彼此协作或相互作用。这里所公开的实施例并不必然限制于本文内容。
“A、B和C中的至少一个”与“A、B或C中的至少一个”具有相同含义，均包括以下A、B和C的组合：仅A，仅B，仅C，A和B的组合，A和C的组合，B和C的组合，及A、B和C的组合。
“A和/或B”，包括以下三种组合：仅A，仅B，及A和B的组合。
如本文中所使用，根据上下文，术语“如果”任选地被解释为意思是“当……时”或“在……时”或“响应于确定”或“响应于检测到”。类似地，根据上下文，短语“如果确定……”或“如果检测到[所陈述的条件或事件]”任选地被解释为是指“在确定……时”或“响应于确定……”或“在检测到[所陈述的条件或事件]时”或“响应于检测到[所陈述的条件或事件]”。
本文中“适用于”或“被配置为”的使用意味着开放和包容性的语言，其不排除适用 于或被配置为执行额外任务或步骤的设备。
另外，“基于”的使用意味着开放和包容性，因为“基于”一个或多个所述条件或值的过程、步骤、计算或其他动作在实践中可以基于额外条件或超出所述的值。
当空调器所处环境(如室外环境)的温度较低时，例如，当室外环境温度低于零下30℃(也称为-30℃)时，空调器上设置的温度传感器，尤其是设置在空调器的室外机中的温度传感器的电阻误差会较大，从而导致温度传感器测量误差较大。在一些示例中，随着环境温度的降低，温度传感器的电阻误差增大，温度传感器的测量精度降低，在这种情况下，温度传感器检测的温度与实际温度之间可能具有较大的误差。
由于温度传感器的检测结果可以对空调器的运行状态起到监控作用，因此温度传感器是否正常运行对于空调器的正常运行具有重要的作用。在相关技术中，判断温度传感器是否故障的方法可以通过直接判断温度传感器的检测温度是否在该温度传感器的允许测量区间内来确定。若温度传感器的检测温度不在允许测量区间，则判定该温度传感器故障。
但是，这种故障判断方法的可靠性较差，很容易导致误判。例如，当室外环境温度低于-30℃时，某些温度传感器仍然可以正常工作，但是，由于较低的室外环境温度可能会影响该温度传感器的测量精度，导致该温度传感器测量误差变大，因而使其检测出的温度超出其允许测量区间。这种情况下，该温度传感器实际上并未发生故障，只是由于室外环境温度影响了其测量精度而导致检测结果超出了允许测量区间，如果按照相关技术中的方法，判定该温度传感器为故障，就发生了误判的情况，而对温度传感器故障情况的误判会影响空调器的运行，降低用户体验。
为此，本公开一些实施例提供一种空调器，该空调器首先对温度传感器的测量误差情况进行判断，可以在其测量误差满足相关条件后，即测量误差不会影响该温度传感器的测量时，再进一步通过判断该温度传感器的测量结果是否处于其允许测量区间来确定该温度传感器是否故障，从而可以降低对温度传感器的故障误判概率。
图1为本公开一些实施例提供的一种空调器的结构图。如图1所示，空调器1包括控制器10、多个温度传感器20和压缩机30。
示例性地，空调器1包括室内机100和室外机200，其中，压缩机30可以设置在室外机200中，且被配置为：工作在运行状态或待机状态。压缩机30在运行状态和待机状态之间进行切换，以实现空调器1的制热或制冷。
需要说明的是，控制器10可以为中央处理器(central processing unit，CPU)、通用处理器网络处理器(network processor，NP)、数字信号处理器(digital signal processing，DSP)、微处理器、微控制器、可编程逻辑器件(programmable logic device，PLD)或它们的任意组合。控制器10还可以是其它具有处理功能的装置，例如电路、器件或软件模块，本公开对此不做限制。
在一些示例中，如图1所示，控制器10可以包括第一控制器11和第二控制器12，其中，第一控制器11可以设置在室内机100中，第二控制器12可以设置在室外机200中，第一控制器11与第二控制器12耦接，第一控制器11与第二控制器12之间可以进行信息互传。
如图1所示，室内机100还包括第一换热器101，室外机200还包括第二换热器201，第一换热器101与第一控制器11耦接，第二换热器201与第二控制器12耦接。
在一些实施例中，多个温度传感器20中的每个温度传感器可以设置在室内机100或者室外机200中。如图1所示，多个温度传感器20可以包括待检测温度传感器21和环境温度传感器22。也就是说，待检测温度传感器21可以为多个温度传感器20中的任一温度传感器。在一些示例中，待检测温度传感器21和环境温度传感器22也可以为同一个温度传感器。本公开一些实施例以待检测温度传感器21和环境温度传感器22设置在室外机200中(如图1)为例进行说明。
在一些实施例中，如图2所示，待检测温度传感器21可以为环境温度传感器22、换热器温度传感器23或压缩机排气温度传感器24。其中，环境温度传感器22可以包括第一环境温度传感221和第二环境温度传感器222，换热器温度传感器23包括第一换热器温度传感器231和第二换热器温度传感器232。
在一些示例中，第一环境温度传感器(也称为室内环境温度传感器)221和第一换热器温度传感器231可以设置在室内机100中，分别与第一控制器11耦接。第二环境温度传感器222、第二换热器温度传感器232和压缩机排气温度传感器24可以设置在室外机200中，分别与第二控制器12耦接。
待检测温度传感器21被配置为检测压缩机30在运行状态之前的待机状态时的环境温度。其中，待检测温度传感器21具有允许测量区间，允许测量区间包括第一阈值和第二阈值，且第一阈值小于第二阈值。
在一些示例中，如图2所示，待检测温度传感器21可以为第一环境温度传感器221、第一换热器温度传感器231、第二环境温度传感器222、第二换热器温度传感器232和压缩机排气温度传感器24中任一温度传感器。待检测温度传感器21根据其设置位置确定其对应的区域，待检测温度传感器21设置位置不同，所对应区域可能不同。
在一些示例中，当待检测温度传感器21的安装位置在室内机100时，其对应区域为室内机100中一些区域。例如，第一环境温度传感器221所对应的区域为室内机100所处区域(也称为室内环境)，第一环境温度传感器221用于检测室内环境的温度；第一换热器温度传感器231设置在室内换热器101上，其所对应区域为室内换热器101的盘管区域，第一换热器温度传感器231用于检测室内换热器101的盘管温度(也称为内盘管温度)。
在另一些示例中，待检测温度传感器21的安装位置在室外机200时，其对应区域为室外机100中一些区域。例如，第二环境温度传感器222所对应的区域为室外机200所处区域(也称为室外环境)，第二环境温度传感器222用于检测室外环境的温度；第二换热器温度传感器232设置在室外换热器201上，其对应区域为室外换热器201的盘管区域，第二换热器温度传感器232用于检测室外换热器201的盘管温度(也称为外盘管温度)；压缩机排气温度传感器24设置在压缩机30的排气管上，其对应区域为压缩机30的排气口，压缩机排气温度传感器24用于检测压缩机30的排气温度。
示例性地，待检测温度传感器21的允许测量区间可以为待检测温度传感器21能够测量到的温度范围，允许测量区间与待检测温度传感器21的物理特性相关，例如，允许测量区间可以由待检测温度传感器21中的电阻决定。
在一些示例中，待检测温度传感器21的允许测量区间可以由第一阈值和第二阈值组成，其中，第一阈值可以待检测温度传感器21能够测量到的最小温度，第二阈值可以为待检测温度传感器21能够测量到的最大温度，第一阈值小于第二阈值。例如，当 待检测温度传感器21的允许测量区间为-40℃至110℃时，表明待检测温度传感器21能够检测到的温度为大于或等于-40℃，且小于或等于110℃的温度，其中，-40℃为其允许测量区间的第一阈值，110℃为其允许测量区间的第二阈值。
环境温度传感器22被配置为检测压缩机30在运行状态之前的待机状态时的环境温度。例如，当环境温度传感器22为第一环境温度传感器221时，其检测到的为室内环境的温度，当环境温度传感器22为第二环境温度传感器222时，其检测到的为室外环境的温度。
环境温度与压缩机30的工作状态相关。由于压缩机30在运行过程中可以产生热量，这些热量通过热传感或者热辐射的方式传递到环境中，从而对环境温度产生影响，例如，可以使得环境温度升高。在这种情况下，环境温度传感器22检测的环境温度可能不是实际的环境温度。而当压缩机30处于待机状态，由于压缩机30已停止运行，因而不会对环境温度造成影响，环境温度传感器22所检测的环境温度与实际的环境温度更加接近。
在一些示例中，压缩机30当前运行状态之前的待机状态可以为压缩机30当前运行状态之前最近的一个待机状态。由于当前运行状态之前最近的待机状态的结束时刻到运行状态的当前时刻的时间较短，因而可以认为该过程中，环境温度保持稳定，因而，根据最近的待机状态时的环境温度传感器22的检测的环境温度更加接近当前运行状态时的环境温度。
控制器10被配置为：获取第一温度；获取第二温度；在压缩机30处于运行状态时，响应于第一温度大于或等于预设基准温度，并响应于第二温度小于所述第一阈值或大于第二阈值，确定待检测温度传感器21故障；或者，响应于第一温度大于或等于预设基准温度，并响应于第二温度大于或等于第一阈值，且小于或等于第二阈值，确定待检测温度传感器21正常。其中，第一温度是根据环境温度得到的；第二温度是根据第一当前温度得到的。
在一些示例中，环境温度传感器22将其检测到的环境温度发送给控制器10，待检测温度传感器21将其检测到的第一当前温度也发送给控制器10，控制器10获取到该环境温度，得到第一温度，并获取第一当前温度后，得到第二温度。
由上述实施例可知，环境温度会影响待检测温度传感器21的测量精度。示例性地，预设基准温度可以是保证待检测温度传感器21的测量产生的误差不会影响其测量结果的环境温度(例如室外环境温度)的下限。也就是说，当环境温度高于或等于预设基准温度时，待检测温度传感器21的测量精度较高，测量误差较小，该测量误差不会影响其检测结果；当环境温度低于预设基准温度时，待检测温度传感器21的测量精度较低，测量误差较大，该测量误差可能会影响到其检测结果。因此，本公开一些实施例通过环境温度与预设基准温度的比较，得到待检测温度传感器21的测量结果的误差情况。
示例性地，预设基准温度可以与待检测温度传感器21的电阻相关。当环境温度发生变化时，待检测温度传感器21的电阻值也会发生改变，在一些示例中，待检测温度传感器21阻值偏差会随着环境温度的变化而变化，例如，待检测温度传感器21的阻值偏差会随着环境温度的降低而增大，而随着待检测温度传感器21的阻值偏差的增大，待检测温度传感器21的测量误差也会随之增大，从而影响待检测温度传感器21的检测结果。
例如，当环境温度低于-30℃时，待检测温度传感器21的阻值偏差增大的较快，从而导致待检测温度传感器21的测量误差随之增大；当环境温度高于-30℃时，如当环境温度达到-25℃时，待检测温度传感器21的阻值偏差增大较慢，此时，待检测温度传感器21的阻值偏差已经较小，使其测量误差可以被忽略。因此，-25℃可以作为待检测温度传感器21的预设基准温度。
需要说明的是，每个待检测温度传感器21的预设基准温度可以相同，也可以不同。本公开一些实施例以每个待检测温度传感器21的预设基准温度相同为例进行说明。例如，每个待检测温度传感器21的预设基准温度可以均为-25℃。
在一些实施例中，如图3所示，空调器1还可以包括存储器40。待检测温度传感器21对应的允许测量区间和预设基准温度可以存储在存储器40中；或者，也可以存储在控制器10中。例如，存储器40可以包括第一存储器41和第二存储器42。其中，第一存储器41与第一控制器11耦接，第二存储器42与第二控制器12耦接。
如图1所示，压缩机30与第二控制器12耦接。第二控制器12可以获取压缩机30的当前工作状态。当控制器10(如第二控制器12)确定压缩机30处于运行状态时，控制器10会根据第一温度与预设基准温度的关系，确定待检测温度传感器21的测量误差情况。
控制器10获取到第一温度后，将第一温度与存储器40中存储的预设基准温度进行比较。由于第一温度是根据压缩机30待机状态时的环境温度得到的，因而采用第一温度与预设基准温度进行比较，可以更加准确的获取到待检测温度传感器21的测量误差情况。
示例性地，第一温度可以为环境温度传感器22(如第二环境温度传感器222)在压缩机30在待机状态结束时刻检测到的室外环境温度；或者，由于压缩机30处于待机状态的时间较短，因而在待机过程中，环境温度(即第一温度)一般比较稳定，变化较小，因此，第一温度也可以为压缩机30处于该待机过程中，环境温度传感器22检测到的多个环境温度中的任一温度，在此不作限定。
例如，当第二控制器12确定第二环境温度传感器222检测的第一温度大于或等于预设基准温度时，表明当前室外环境温度对待检测温度传感器21的测量精度影响较小，不会影响到待检测温度传感器21的测量结果。因此，待检测温度传感器21在运行状态时检测的第一当前温度(即第二温度)是没有受到测量误差影响，且较为准确的环境温度，此时，再通过第二温度与待检测温度传感器21的允许测量范围的关系，确定待检测温度传感器21故障与否会更为准确。
在压缩机30处于运行状态时，控制器10获取第二温度包括：第一控制器11或第二控制器12获取第二温度。其中，若待检测温度传感器21设置在室内机100中，可以由第一控制器11获取第二温度；若待检测温度传感器21设置在室外机200中，可以由第二控制器12获取第二温度。
在一些示例中，当待检测温度传感器21为第二环境温度传感器222时，第一当前温度为室外环境的当前温度；当待检测温度传感器21为第二换热器温度传感器232时，第一当前温度为室外盘管的当前温度；或者，当待检测温度传感器21为压缩机排气温度传感器24时，第一当前温度为压缩机30排气的当前温度。
控制器10获取到第二温度后，判定第二温度与待检测温度传感器21的允许测量区 间的关系。当第二温度不在待检测温度传感器21的允许测量区间内，也就是当第二温度小于第一阈值，或者大于第二阈值时，表明待检测温度传感器21的当前测量到的温度超过了其允许测量区间，则可以确定待检测温度传感器21故障。
当第二温度在待检测温度传感器21的允许测量区间内，也就是当第二温度小于或等于第一阈值，且小于或等于第二阈值时，表明待检测温度传感器21的当前测量到的温度没有超出其允许测量区间，则可以确定待检测温度传感器21处于正常运行的状态。
本公开一些实施例提供的空调器1通过对压缩机30处于当前运行状态之前的待机状态时的环境温度与预设基准温度的大小比较，确定出待检测温度传感器21的测量误差情况。在保证待检测温度传感器21的测量误差不会影响其检测结果的情况下，再确定待检测温度传感器21检测的第一当前温度与其允许测量区间的关系，进而判断待检测温度传感器21的故障情况。因此，相比于相关技术中直接通过待检测温度传感器21检测的温度是否在允许测量区间内来判断待检测温度传感器21是否故障的情况，本公开一些实施例提供的空调器1的判断结果更加精确，进一步降低了待检测温度传感器21的故障误判概率。同时，由于减少了待检测温度传感器21的故障误判的发生，也可以提高空调器1的使用安全性和舒适性。
在一些实施例中，控制器10还被配置为：获取压缩机30的运行时间，其中，运行时间为压缩机30从运行状态之前的待机状态的结束时刻至运行状态的当前时刻的时间；在压缩机30处于运行状态时，响应于第一温度小于预设基准温度、响应于运行时间大于或等于预设时间，以及响应于第二温度小于第一阈值或大于第二阈值，确定待检测温度传感器21故障。
在压缩机30处于运行状态时，若控制器10获取到的第一温度小于预设基准温度，表明环境温度可能会影响待检测温度传感器21的测量精度，造成待检测温度传感器21的检测结果存在较大的误差，此时，如果通过待检测温度传感器21检测的当前温度不在其允许测量区间来判定待检测温度传感器21故障可能会造成误判，从而影响空调器1的运行。因此，在一些示例中，当第一温度小于预设基准温度时，控制器10可以判定待检测温度传感器21为正常。
在另一些示例中，由于压缩机30自待机状态结束进入当前运行状态后，会持续产生热量，这些热量会传递给待检测温度传感器21。随着压缩机30的运行时间的增大，待检测温度传感器21的温度得到较大的提升，待检测温度传感器21的测量精度也会提高。当运行时间达到预设时间时，待检测温度传感器21的测量精度可以保证其测量误差不会影响测量结果，此时，再通过判断第二温度与待检测温度传感器21的允许测量区间的关系，可以进一步提高待检测温度传感器21故障判定的准确率。
示例性地，预设时间可以为保证待检测温度传感器21的测量误差不会影响其测量结果时压缩机30的运行时间。在一些示例中，待检测温度传感器21不同，其预设时间可以不同。例如，当待检测温度传感器21为压缩机排气温度传感器24时，其预设时间可以为10分钟。
当压缩机30的运行时间没有达到预设时间时，待检测温度传感器21的测量误差可能会影响其检测结果，此时，控制器10不能通过第二温度不在待检测温度传感器21允许测量区间来判定待检测温度传感器21故障；或者，控制器10可以判定待检测温度传感器21为正常；或者，控制器10可以在压缩机30的运行时间达到预设时间时，再判断待检测温 度传感器21的故障情况，从而可以进一步减小待检测温度传感器21的故障误判率。
在一些实施例中，待检测温度传感器还被配置为：检测压缩机处30处于待机状态时对应区域的第二当前温度。控制器10还被配置为：获取第三温度，在压缩机30处于待机状态时，响应于第三温度小于第一阈值或大于第二阈值，确定待检测温度传感器21故障。或者，响应于第三温度大于或等于第一阈值，且小于或等于第二阈值，确定待检测温度传感器21正常。其中，第三温度是根据第二当前温度得到的。
在一些示例中，若待检测温度传感器21为环境温度传感器(如第二环境温度传感器222)或换热器温度传感器(如第二换热器温度传感器232)，当压缩机30结束运行状态，并进入到待机状态时，待检测温度传感器21在压缩机30的上一个运行状态期间都被加热，而随着待检测温度传感器21温度的升高，其测量精度也会提高，因而在压缩机30处于待机状态时，待检测温度传感器21的测量误差较小，不会影响其测量结果，因此，待检测温度传感器21在待机状态时所检测的第二当前温度也会较为准确的。
因此，在压缩机30处于待机状态时，控制器10可以通第三温度与待检测温度传感器21的允许测量区间的关系判定待检测温度传感器21是否故障。当第三温度不在待检测温度传感器21的允许测量区间时，判定待检测温度传感器21故障；当第三温度在待检测温度传感器21的允许测量区间时，判定待检测温度传感器21正常。
在一些实施例中，控制器10还被配置为：在压缩机30处于待机状态时，响应于第一温度大于或等于预设基准温度，并响应于第三温度小于第一阈值或大于第二阈值，确定待检测温度传感器21故障。
示例性地，当待检测温度传感器21为压缩机排气温度传感器24时，由于排气温度传感器24在较低的环境温度下，测量误差较大。这种情况下，可以先通过判断压缩机30处于待机状态时的环境温度是否会影响待检测温度传感器21的测量精度，再判断待检测温度传感器21检测的第二当前温度是否在其允许测量区间来判定待检测温度传感器21的故障情况，可以进一步减小待检测温度传感器21的故障误判率。
若第一温度大于或等于预设基准温度，表明待检测温度传感器21当前的测量误差不会影响待检测温度传感器21的测量结果，此时，控制器10可以通过判断第三温度是否在待检测温度传感器21允许测量区间内，来确定待检测温度传感器21是否故障。
若第一温度小于预设基准温度，待检测温度传感器21的测量误差可能较大，因此，控制器10不能通过第三温度不在待检测温度传感器21的允许测量区间判定其故障。在一些示例中，这种情况下，控制器10可以判定待检测温度传感器21处于正常状态。
在一些实施例中，控制器10还被配置为：对环境温度进行模数变换，得到第一温度；对第一当前温度进行模数变换，得到第二温度；对第二当前温度进行模数变换，得到第三温度。
在一些示例中，空调器1在运行过程中，控制器10(如第一控制器11和/或第二控制器12)可以分别对其获取到的环境温度、第一当前温度和第二当前温度进行模数转换，得到第一温度、第二温度和第三温度，并且采用第一温度与预设基准温度进行比较，采用第二温度和第三温度分别与待检测温度传感器21允许测量区间的第一阈值和第二阈值进行比较。在一些示例中，预设基准温度和待检测温度传感器21允许测量区间的第一阈值和第二阈值均可以是通过模数转换后的温度。采用模数转换后的温度进行上述比较运算，可以提高故障判定过程的效率。
