背景技术
空调器耗电高是限制空调器广泛使用的一个重要原因，尤其是针对民用使用场所。实际上，用户几乎不能清楚地了解到空调器中各个部件的实际耗电情况，也不了解空调器在不同的运行模式下的实际耗电情况。用户对于空调器耗电的基本认知来自于科普新闻的宣传和传统的认知，这不仅不能帮助用户节约能耗，更可能促使用户按照普通家用电器的使用习惯选择不合理的空调使用方式，比如为了省电频繁地开关变频空调器等，这一方面牺牲了用户体验，另一方面并未达到节能省电的目的。
为了帮助用户了解使用空调器时的电量，现有技术中设计了多种方式检测空调器使用时的电量消耗，如中国专利申请(申请号2013102004604)《空调器的电能检测方法及电能检测装置》中公开的技术方案，根据输入交流电的电压瞬时值和输入交流电的电流瞬时值计算空调器在预设时间段内的电能信息。这种方法的检测精度较低，用户也很难了解自己对空调器的控制方式对空调器电量的影响。为了进一步提高检测的精度，现有技术中还设计了根据既定的经验模型计算空调器耗电量的方法，如中国专利(申请号2015104690759)《空调器的耗电量检测方法、装置和空调器》中所公开的技术方案“获取室内机导风条的角度、室内换热器的温度、室内温度和室内环境湿度，通过建立与室外机的电压有效值、室内机的导风条的角度、室内换热器的温度、室内环境温度和室内环境湿度相关联的功 率估计模型函数估算室内风机的运行功率；…室内控制其将室内换热器的温度、室内风机的运行功率和室外机的电压有效值作为第一输入变量，以及根据第一输入变量对PTC加热器的运行功率进行建模以估算出PTC加热器的运行功率。”不难理解，对于空调器来说，其内部设置的数据处理系统的能力有限，复杂的数据模型必定会降低空调器数据处理的速度和精度，进一步导致处理器无法快速响应用户请求，同时，由于各个部件之间的复杂联动的耦合关系，更无法根据用户请求计算显示其中部分部件的耗电量。而且，作为输入参数，室内换热器的温度、室内环境温度和室内环境温度的检测存在明显的滞后性，很难在很短的时间内准确的计算出理想的耗电量数据。此外，上述专利申请中得到的复杂数据模型依赖于模式识别法计算补偿值，对于每一款空调的每一个模式，必须根据实验经验数据得到至少七个模型经验常数。面对功能模式越来越多的空调器，造成实验数据量庞大，耗时耗力。
综上所述，现有技术中所公开的空调器消耗电量检测方法，无法在保证快速响应用户请求的前提下，形成一种准确、快速、灵活的空调器耗电量检测方法。

附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作一简单地介绍，显而易见地，下面描述中的附图是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。
图1为本发明所公开的基于单模块的空调器电量检测方法第一种实施例的流程图；
图2为本发明所公开的基于单模块的空调器电量检测方法第二种实施例的流程图。
具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
参见图1所示为本发明所公开的基于单模块的空调器电量检测方法第一种实施例的流程图。如图所示，具有由以下步骤实现。
与现有技术完全不同，首先，整个空调器电量检测的数据处理通过数据处理装置实现，数据处理装置优选为一颗独立的MCU，以提高整个电量计算过程的精度和速度；数据处理装置也可以是由室内机的控制芯片实现。在检测电量的过程中，数据处理装置接收包括一组开关信号的第一输入指令。第一输入指令可以来源于空调器的遥控装置，包括但不限于传统的红外遥控器，以及通过软件接口开放的智能终端遥控装置。第一输入指令还可以来源于与室内机主板的通信。室内机主板接收遥控信号生成并传输第一输入指令至数据处理装置。数据处理装置响应第一输入指令以接收空调器的开关状态。数据处理装置还可以接收包括待机信号的待机指令。数据处理装置响应待机指令以接收空调器的待机状态，通过数据处理装置监控在待机状态下空调器的耗电情况，这部分的电量通常是来源于待机状态显示装置、空调器的开关电源、控制板的芯片的基本能耗。
在数据处理装置开始运行之前，还接收包括至少一个计时信号的第二输入指令。第二输入指令中的计时信号对应一个固定的消耗电量统计计时周期， 计时周期可以是用户设定的，也可以是出厂时的默认设定，数据处理装置响应第二输入指令以接收计时周期。计时周期的时长优选为数小时，足以保持空调器的工作状态相对稳定。在空调器的一次启停控制中，也可以通过第二输入指令通过多个计时信号确定多个计时周期。
数据处理装置关联第一输入指令和第二输入指令，进一步确定空调器在计时信号对应的计时周期中的室内机功率和/或室外机功率。主要的，数据处理装置根据设定的计时周期确定在本次开关状态中，室内机功率、室外机功率的变化趋势，并在设定的时间节点计算对应的电量。具体来说，其中室内机功率包括室内机主电路板功率、室内显示模块功率、室内风机功率、电加热功率中的至少一个单模块功率，室外机功率包括室外机主电路板功率、压缩机运行功率、室外风机功率、电子膨胀阀功率、四通阀功率中的至少一个单模块功率。在数据处理装置中，每一个单模块功率均独立计算和存储，并可以独立调用。在确定室内机功率和/或室外机功率的过程中，数据处理装置同时判定每一个单模块的功率是否在合理的区间内，如果超出了合理的区间，则生成报警信号。
数据处理装置进一步接收包括模块选定信号的第三输入指令。数据处理装置响应第三输入指令以接收模块选定信息。模块选定信号默认设定对应的选定模块为空调整机，即在第一输入指令确定的空调器启停状态下，在第二输入指令设定的计时周期中，空调器各个单模块整体消耗电量之和。在本实施例中，一种更为优选的方式是，模块选定信号接受用户的主动干预，用户可以通过遥控终端或者通过室内机主板主动输出包括进行干预的模块选定信号的第三输入指令。比如，用户通过模块选定信号主动选择获知其中某一个单模块的消耗电量，或者独立的室内机消耗电量，以及独立的室外机消耗电量。数据处理装置响应第三输入指令，确定关联第一输入指令、第二输入指令和第三输入指令的室内机消耗电量和/或室外机消耗电量，进一步调用、显示和/或传输室内机消耗电量、室外机消耗电量至指定的用户终端、服务器、 云平台或者空调器的显示装置。一种优选的方式为，第三输入指令优选为一组遥控器编码信号，遥控器编码信号分别对应选定的模块为每一个单模块、室内机包括的全部单模块、室外机包括的全部单模块以及整机包括的全部单模块。遥控器编码信号通过遥控终端上的按键，以及在按键上的动作生成。以显示动作为例，数据处理设备接收到对应的编码信号后，在选定的显示设备上连续或切换显示对应设定时长的各个单模块消耗电量、室内机消耗电量、室外机消耗电量、整机消耗电量，从而使得用户可以清楚地了解到在计时周期中空调器各个功能部件的耗电情况。由于数据处理装置独立设置、各个单模块的数据计算互不干扰，也不受到空调运行模式的影响，数据计算过程精确、响应快速。进一步的，在计算过程中，通过第一输入指令包括的开关信号对应的启停时刻配合MCU的时钟可以得到空调器的运行季节以及对应的外部环境数据，传输至云平台从而通过关联得到外部环境数据、空调运行时长和各单模块消耗电量之间的关系，作为进一步优化控制空调器运行的基础，或者生成图表，作为指导用户合理使用空调的基础。这种分析方式不依赖于变化频次较高的换热器温度、室内温度以及环境温度等参数，对于用户来说更为直观准确。
本实施例所提供的单模块的空调器电量检测方法，由用户主动控制空调器的启停状态并选定电量消耗的计时周期，通过数据处理装置关联空调启停状态和计时周期确定空调器中各个单模块的功率，独立计算并存储，并根据用户可以主动干预的模块选定过程，计算并调用、显示、传输其中任意一个单模块的消耗电量，整个关联、确定、计算、调用过程不依赖于空调房间的环境参数或者复杂的数据模型，具有数据计算精度高、响应速度快且灵活性好的优点。
在根据第一输入指令、第二输入指令和第三输入指令关联确定各个单模块、室内机、室外机或整机的消耗电量的过程中，以显示动作为例，生成显示值是一个连续并不断累积变化的叠加值，由于数据传递延时以及处理器数 据处理能力的限制，叠加计算的过程在一定程度上存在数据的冗余。为了降低数据的冗余量，数据处理装置响应第三输入指令后，首先判断计时信号对应的计时周期中模块选定信号对应的选定模块的功率变化趋势。如果变化趋势满足设定条件，则即刻将关联第一输入指令、第二输入指令和第三输入指令的室内机功率和/或室外机功率换算为消耗电量后显示和/或传输，并记录对应的时间节点。如果变化趋势不满足设定条件，则在计时周期终止时以计时周期终止时为时间节点，将关联第一输入指令、第二输入指令和第三输入指令的室内机功率和/或室外机功率换算为消耗电量后显示和/或传输。从而避免过于频繁的进行运算，降低数据处理量并去除冗余的数据，降低单模块计算和多模块累加值之间的误差，提高检测精度。
判断变化趋势的设定条件优选为在所述计时周期中，选定模块功率的增量是否大于设定值，增量的定义为连续两个时间点选定模块变化值的绝对值。例如选定模块相对于前一秒的功率增量。如果功率增量大于设定值，则将关联第一输入指令、第二输入指令和第三输入指令的室内机功率和/或室外机功率换算为消耗电量后显示和/或传输，并记录对应的时间节点。如果不大于设定值，则在计时周期终止时，将关联所述第一输入指令、第二输入指令和第三输入指令的室内机功率和/或室外机功率换算为消耗电量后显示和/或传输，并将计时周期终止时作为时间节点记录。优选的，设定值∈(5W，10W)。
同时，数据处理装置将换算出的消耗电量传输至服务器中存储。用户可以查询任意一个消耗电量。具体来说，数据处理装置接收包括至少一个查询信号的第四输入指令，服务器接收并响应第四输入指令，调取查询信号对应的任意一个时间段内的所述消耗电量。例如，空调器在[T 1，T 2]时间段内运行，查询信号对应查询[T 3，T 4]时间段内的消耗电量，服务器调取查询时间段内多个时间节点的消耗电量，并进一步传输或者显示。
空调器的使用环境中复杂的环境参数，以及其各个功能部件的运行状态是复杂耦合的关系，基本无法得到一个单一的公式确定之间的关系，更很难 利用一个数据模型确定环境参数对部件运行状态，进一步补偿对消耗电量的影响。与现有技术中建立复杂的数据模型确定每一个单模块的功率不同。本发明所公开的单模块空调器电量检测方法利用每一个单模块的物理性质和经验值确定其在计时周期中的功率，简化各个部件之间的耦合关系，保持各个单模块的电量计算相对独立，无需采用针对不同机型以及空调环境进行大量的实验建模。
具体来说，为了达到上述目的，确定室内机功率时：
所述室内机主电路板功率P g’等于芯片额定功率。室内机主电路板功率P g’主要为主芯片工作时的功率以及待机工作的其它元器件功率的总和。一般在0-5W区间，数据处理装置根据第一输入指令和第二输入指令确定该模块功率及功率变化趋势时，优选与这一区间进行对比，确定落入该区间后存储或输出。
所述室内显示模块功率P x等于控制板功率P g”与处于工作状态的提示灯的功率P”之和。其中，控制板功率P g”为控制板上所有器件工作时的总功率。提示灯功率为P”＝P L*X,其中P L为单个提示灯点亮的功率，X为电量的提示灯的数量。
所述室内风机功率P f1通过检测室内风机驱动占空比获得。当室内风机驱动占空比d<d 1时，所述室内风机功率P f1＝P 1；当风机驱动占空比d m-1<d<d m时，所述室内风机功率
Figure PCTCN2018092556-appb-000005
当风机驱动占空比d>d n时，所述室内风机功率P f1＝P n，其中1≤m≤n，m，n为整数，m，n∈[1，5]，其中，d 1，d m-1，d m，d n为递增的常数，P 1，P m-1，P m为递增的设定值。优选的，n＝5,d 1＝10％,d 2＝30％,d 3＝60％,d 4＝85％,d 5＝95％，P 1＝7W,P 2＝22W,P 3＝46W,P 4＝90W,P 5＝110W。举例来说，如果室内风机驱动占空比为70％，则室内风机功率
Figure PCTCN2018092556-appb-000006
根据不同的机型，仅需要根据不同电机的能力调整设定值的数值即可，在保证风机消耗电量计算独立的同时，无 需重新检测并计算经验公式。
所述电加热功率P t为额定电加热功率P t0。
针对大部分的情况，电加热功率P t受到室内风机的运行状态的影响。为了提高电加热功率P t的计算精度，同时对风机的运行状态进行校正和补偿，在另一种实施方式中，电加热功率P t等于设定电加热功率P t0和校正电加热功率P t’之和，校正电加热功率P t’随所述室内风机驱动占空比的增加而增加。具体来说，设定电加热功率P t0为一个常数值，可以根据电加热的不同型号进行选取。校正电加热功率P t’与室内风机的转速有关，优选的，校正电加热功率P t’对应室内风机驱动占空比分为多个数据段，每一个数据段具有对应的校正权重w，校正电加热功率P t’在每一个数据段中随所述室内风机驱动占空比的增加而增加，校正电加热功率P t’的增量等于风机驱动占空比和权重值乘积的累加值。举例来说，对于某一型号的电加热装置，设定电加热功率P t0为630W。校正电加热功率P t’根据室内风机驱动占空比按照以下列表分为多个数据段，每一个数据段具有对应的校正权重w。
d 40％-50％ 50％-60％ 60％-80％ 80％-95％
w 700 700 300 200
如果当前检测到的室内风机占空比为70％，则校正电加热功率为(50％-40％)*700+(60％-50％)*700+(70％-60％)*300＝170W。电加热功率P t等于设定电加热功率P t0和校正电加热功率P t’之和，即630W+170W＝800W。
当室内风机运行时，导风板的位置同样也会对电加热的功率造成影响，为了对导风板角度形成的误差进行校正，如果导风板运行，则电加热功率P t＝(P t0+P t’)k 1，其中k 1为导风板校正系数，所述导风板校正系数随所述导风板偏离原始位置距离的增加而增加；k 1∈(0.9，1.1)。优选的，导风板处于标准位置时，k 1＝1，标准位置为设定的运行位置，标准位置优选为步进电机设定步长信号对应运行位置。如果偏离该标准位置，则通过导风板校正系数对 其进行校正，一组具体的优选导风板校正系数如下表所示：
偏离角度 ＜-20° -20°～-10° -10°～-5° -5°～5° 5°～10° 10°～20° ＞20°
k1 0.94 0.96 0.98 1 1.02 1.05 1.08
进一步的，确定室外机功率时，
所述室外机主电路板功率P g等于芯片额定功率。室外机主电路板功率P g主要为主芯片工作时的功率以及待机工作的其它元器件功率的总和。一般在0-5W区间内，数据处理装置根据第一输入指令和第二输入指令确定该模块的功率以及功率变化趋势时，优选与这一区间进行对比，确定功率值不超过该区间后存储或输出。
所述压缩机运行功率

其中U为电源电压有效值，I为电源电流有效值。
在获得室外风机功率P f2时，首先需要确定室外风机的类型。
如果室外风机为直流风机，则当室外风机驱动占空比d<d 1时，所述室外风机功率P f2＝P 1；当风机驱动占空比d m-1<d<d m时，所述室外风机功率
Figure PCTCN2018092556-appb-000008
当风机驱动占空比d>d n时，所述室外风机功率P f2＝P n，其中1≤m≤n，m，n为整数，m，n∈[1，5]，其中，d 1，d m-1，d m，d n为递增的常数，P 1，P m-1，P m为递增的设定值。优选的，n＝5,d 1＝10％,d 2＝30％,d 3＝60％,d 4＝85％,d 5＝95％，P 1＝7W,P 2＝22W,P 3＝46W,P 4＝90W,P 5＝110W。举例来说，如果室外风机驱动占空比为70％，则室外风机功率
Figure PCTCN2018092556-appb-000009
根据不同的机型，仅需要根据不同电机的能力调整设定值的数值即可，在保证风机消耗电量计算独立的同时，无需重新检测并计算经验公式。
由于交流风机不论是双速风机还是单速风机都采用开环控制。所以，如果室外风机为交流风机，则首先根据室外风机的转速选取对应的额定功率设定值P f2’。选取对应的额定功率设定值P f2’时，优选根据室外风机的转速，将 额定功率分为两档，对应每一档风速对应分配一个额定功率值P 01和P 02。判定当前室外风机的转速所属的风速档位，进而选取对应的额定功率值作为额定功率设定值P f2’。根据实际应用场景的不同，也可以设定跟多的额定功率值作为额定功率设定值。
室外风机功率P f2等于额定功率设定值和电压修正参数k 2的乘积，且室外风机功率P f2随市电电压的增加而增加，k 2∈(0.9，1.1)。一组具体的优选导风板校正系数如下表所示：
市电电压(V) ＜200 ＜210 200 ＞230 ＞240
k 2 0.9 0.95 1 1.05 1.1
所述电子膨胀阀功率P d等于电子膨胀阀额定功率。控制电子膨胀阀的电机的动作时间较短，功率通常在0-5W之间，优选为3W。
所述四通阀功率P s等于四通阀额定功率,四通阀仅在制热模式运行，功率通常在0-5W之间，优选为4W。
在上述实施例中，室内机和室外机各模块的功率确定彼此相对独立，同时对耦合关系进行了适度校正，保证了数据的准确性，同时也确保了每一个单模块的功率可以独立确定、调用，并根据计时周期进行消耗电量的计算。经过实验，可以将空调器电量检测的误差控制在5％以内。
本发明同时还公开了一种空调器，采用如上述实施例所公开的任意一种基于单模块的空调器电量检测方法。本发明所公开的空调器中，可以根据用户需求，或者厂家的需求传输、显示、调用、计算设定计时周期中任意一个单模块，或多个单模块的消耗电量，检测计算的过程中，各模块保证相对独立，且计算过程与空调使用环境的耦合关系小，计算精度高且灵活。同时还避免了繁杂的建模过程，使得用户可以了解各个单模块、室内机、室外机以及整机的实际消耗电量，并根据实际耗电量建立良好的使用习惯，在保证使用舒适性的同时起到节约能耗的目的。基于单模块的空调器电量检测方法的具体步骤详见上述实施例的详细描述，在此不再赘述。
最后应说明的是：以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
