Description

用于空调器的控制方法及装置、空调器、存储介质
本申请基于申请号为202210905603.0、申请日为2022年7月29日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及空调器技术领域，例如涉及一种用于空调器的控制方法及装置、空调器、存储介质。
背景技术
目前，直流空调器系统的电能来源包括光伏、风能等发电设备提供的直流电。为保证电能供应的突发情况，直流空调器系统还接入绿色能源供电装置以及UPS(uninterruptible power supply，不间断电源)，以在绿色能源供电装置的发电量充足时进行电量储备，并在绿色能源供电装置发电量不足时释放能量进行电能供应。然而，在绿色能源供电装置接入或者退出直流空调器系统时，极易产生直流电网母线电压瞬时跌落的情况。由此，将对压缩机的运行产生较大影响，甚至造成压缩机停机。针对直流空调器出现的母线电压跌落情况，对母线电压检测的实时性提出更高的要求。
相关技术公开一种电压检测方法，包括：采集母线的电压数据并确定对应的截止频率；根据截止频率对电压数据进行滤波以得到电压检测数据；根据电压检测数据确定对应的检测值，并根据检测值和对应的检测阈值确定母线对应的电压检测结果。该方法得到的电压检测结果能够反映母线电压变化，从而确定能够反映母线电压波动的检测值，根据检测值完成对母线电压是否出现跌落、断电等波动的检测，有效地防止母线电压波动对用电设备造成的影响，提高了供电检测的可靠性和用户设备运行的可靠性。
在实现本公开实施例的过程中，发现相关技术中至少存在如下问题：
相关技术能够实现对母线的电压值的实时检测，并根据检测值获知母线电压是否跌落。然而，在直流空调器以自清洁模式运行出现上述母线电压跌落时，上述电压检测方法无法保证压缩机持续稳定的运行，影响直流空调器以自清洁模式运行的稳定性。
发明内容
为了对披露的实施例的一些方面有基本的理解，下面给出了简单的概括。所述概括不 是泛泛评述，也不是要确定关键/重要组成元素或描绘这些实施例的保护范围，而是作为后面的详细说明的序言。

具体实施方式
为了能够更加详尽地了解本公开实施例的特点与技术内容，下面结合附图对本公开实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本公开实施例。在以下的技术描述中，为方便解释起见，通过多个细节以提供对所披露实施例的充分理解。然而，在没有这些细节的情况下，一个或多个实施例仍然可以实施。在其它情况下，为简化附图，熟知的结构和装置可以简化展示。

术语“和/或”是一种描述对象的关联关系，表示可以存在三种关系。例如，A和/或B，表示：A或B，或，A和B这三种关系。
术语“对应”可以指的是一种关联关系或绑定关系，A与B相对应指的是A与B之间是一种关联关系或绑定关系。
相关技术公开一种电压检测方法，包括：采集母线的电压数据并确定对应的截止频率；根据截止频率对电压数据进行滤波以得到电压检测数据；根据电压检测数据确定对应的检测值，并根据检测值和对应的检测阈值确定母线对应的电压检测结果。该方法得到的电压检测结果能够反映母线电压变化，从而确定能够反映母线电压波动的检测值，根据检测值完成对母线电压是否出现跌落、断电等波动的检测，有效地防止母线电压波动对用电设备 造成的影响，提高了供电检测的可靠性和用户设备运行的可靠性。
相关技术能够实现对母线的电压值的实时检测，并根据检测值获知母线电压是否跌落。然而，在直流空调器以自清洁模式运行出现上述母线电压跌落时，上述电压检测方法无法保证压缩机持续稳定的运行，影响直流空调器以自清洁模式运行的稳定性。
结合图1所示，本公开实施例提供一种用于空调器的控制方法，包括：
S01，空调器获取空调器的母线电压信息。
S02，空调器在母线电压信息表示母线电压跌落的情况下，获取空调器在自清洁模式下的运行时长。
S03，空调器在运行时长不满足预设时长条件的情况下，控制空调器执行弱磁功能，以调节压缩机的转速值。
采用本公开实施例提供的用于空调器的控制方法，空调器根据母线电压信息确定母线电压跌落时，判断空调器在自清洁模式下的运行时长是否满足预设时长条件。若不满足，则表明压缩机的当前转速值未达到维持自清洁模式的基准转速值。空调器执行弱磁功能以使压缩机的转速值增大至基准转速值后维持一定时长，从而通过执行弱磁功能使压缩机持续稳定地运行，有利于提升直流空调器自清洁运行的稳定性。
可选地，预设时长条件包括运行时长大于或者等于预设时长值。
其中，预设时长值表示已完成空调器的基本清洁的时长值。在空调器以预设时长值执行自清洁模式后，后续清洁阶段边际效应递减。
这样，在运行时长不满足预设时长条件时，表明压缩机的当前转速值未达到维持自清洁模式的基准转速值。为此，空调器执行弱磁功能以使压缩机的转速值增大，最终，达到基准转速至并维持一定时长。
需要说明的是，空调器控制空调器执行弱磁功能后，还包括：空调器获取压缩机的新的转速值。空调器判断新的转速值是否大于或者等于基准转速值，若否，则继续执行弱磁功能。若是，则关闭弱磁功能。这样，能够实时获知执行弱磁功能后压缩机的转速值是否达到基准转速值，并根据压缩机的转速值控制弱磁功能持续执行或者关断。由此，提升弱磁调节的准确性和实时性。
可选地，结合图2所示，空调器控制空调器执行弱磁功能，包括：
S11，空调器获取空调器的指令电压值。
S12，空调器根据指令电压值与预设阈值的匹配情况，控制弱磁电流幅值和/或弱磁电流补偿角度值增大。
这样，由于指令电压值须满足小于预设阈值的判断条件。在空调器执行弱磁功能时， 将指令电压值与母线电压的有效值进行比较，若指令电压值不满足上述判断条件，则控制弱磁电流值和/或弱磁电流补偿角度值增大，从而通过持续运行弱磁功能来增大压缩机的转速值至基准转速值并维持一定时长。
其中，预设阈值为母线电压的有效值。作为一种示例：母线电压的有效值等于其中，Ed表示母线电压的幅值最大值。
可选地，结合图3所示，空调器根据指令电压值与预设阈值的匹配情况，控制弱磁电流幅值和/或弱磁电流补偿角度值增大，包括：
S21，空调器在指令电压值小于母线电压的有效值的情况下，以第一预设变化量增大弱磁电流幅值。
S22，空调器重新获取新的指令电压值。
S23，空调器在新的指令电压值等于母线电压的有效值的情况下，以第二预设变化量增大弱磁电流补偿角度值。
这样，空调器在以第一预设变化量增大弱磁电流幅值后，将导致指令电压值增大且逐步接近于母线电压的有效值。为兼顾指令电压值满足小于预设阈值的判断条件，空调器在新的指令电压值等于母线电压的有效值的情况下，增大弱磁电流角度值以继续执行弱磁功能以使压缩机的转速值增大至基准转速值后维持一定时长。
需要说明的是，空调器以第二预设变化量增大弱磁电流补偿角度值时，第二预设变化量还满足以下条件：0<第二预设变化量≤30rad。
可选地，结合图4所示，按照以下方式获得预设变化量：
S31，空调器从母线电压信息中提取母线电压的当前跌落幅值。
S32，空调器根据跌落幅值，确定预设变化量。
这样，空调器可根据母线电压的当前跌落幅值对应调整弱磁电流值和/或弱磁电流补偿角度值，使得弱磁电流值和/或弱磁电流补偿角度值与当前跌落幅值相适配。提升弱磁调控的准确性。
可选地，空调器根据跌落幅值，确定预设变化量，可以根据以下公式确定预设变化量：
a×ΔEd+b；
其中，ΔEd表示母线电压的跌落幅值，a表示第一系数，b表示第二系数且a<0,b>0。预设变化量包括第一预设变化量和/或第二预设变化量。
这样，可获得与母线电压的跌落幅值呈线性函数关系的第一预设变化量和/或第二预设变化量，能够有效地提升弱磁调控的准确性。
可选地，结合图5所示，按照以下方式确定母线电压跌落：
S41，空调器从母线电压信息中提取跌落速率以及跌落幅值。
S42，空调器在跌落速率大于预设跌落速率且跌落幅值大于预设跌落幅值的情况下，确定母线电压跌落。
这样，空调器在跌落速度大于预设跌落速率且跌落幅值大于预设跌落幅值时，表明母线电压发生跌落。该方法可实现母线电压跌落的准确判断。
需要说明的是，空调器配置有母线电压检测电路。母线电压检测电路用于采集母线电压信息，并从母线电压信息中提取跌落速率和跌落幅值。
结合图6所示，本公开实施例还提供一种用于空调器的控制方法，包括：
S51，空调器获取空调器的母线电压信息。
S52，空调器在母线电压信息表示母线电压跌落的情况下，获取空调器在自清洁模式下的运行时长。
S53，空调器判断运行时长是否满足预设时长条件，若否，则执行S54。若是，则执行S55。
S54，空调器控制空调器执行弱磁功能，以调节压缩机的转速值。
S55，空调器控制压缩机执行降频操作。
采用本公开实施例提供的用于空调器的控制方法，空调器在运行时长满足预设时长条件时，表明空调器已完成基本清洁。若仍然继续采取提升压缩机的转速值以维持基准转速值执行自清洁，提升空调器的能耗且经济效益不佳。综合空调器能耗以及经济效益，空调器执行降频操作，保证自清洁模式能够维持运行的同时节约电能消耗。
可选地，空调器控制压缩机执行降频操作，可以为以预设频率变化量降低压缩机频率。前述预设频率变化率可以根据空调器的型号确定，也可以根据用户对于所在环境的温度需求确定。本公开实施例对此可不做具体限定。
这样，使空调器的压缩机的频率缓慢降低，避免因频率突降而影响压缩机的稳定运行，提升空调器运行的可靠性。
作为一种示例，预设频率变化率根据空调器的型号确定，预设频率变化率满足以下条件：当前频率×0.2≤预设频率变化量≤当前频率×0.5。其中，当前频率表示空调器控制压缩机执行降频操作时获取的压缩机的频率值。
在实际应用中，预设运行时长为10分钟。用于空调器的控制方法具体执行以下步骤：
S61，空调器通过母线电压检测电路获得母线电压信息，并从母线电压信息中提取跌落幅值ΔEd和跌落速率λ。经判断，ΔEd大于预设跌落幅值且λ大于预设跌落速率。由此，确定母线电压跌落。
S62，空调器获取空调器以自清洁模式运行的运行时长，经判断，运行时长为8分钟。该运行时长小于预设运行时长，空调器执行弱磁功能。
S63，空调器获取指令电压值V。经判断，
空调器以第一预设变化量ΔId增大弱磁电流幅值。
ΔId＝a×ΔEd+b。
S64，空调器重新获取母线电压信息，并从上述新的母线电压信息中提取新的跌落幅值ΔE′d和新的跌落速率λ′。将判断，λ′小于预设跌落速率且ΔE′d大于预设跌落幅值。由此，表明通过对弱磁电流幅值进行上述调节，使母线电压不再持续跌落且压缩机的转速值增大至基准转速值并可维持一定时长。
结合图7所示，本公开实施例提供一种用于空调器的控制装置70，包括获取模块201、判断模块202和执行模块203。获取模块201被配置为获取空调器的母线电压信息；判断模块202被配置为在母线电压信息表示母线电压跌落的情况下，获取空调器在自清洁模式下的运行时长；执行模块203被配置为在运行时长不满足预设时长条件的情况下，控制空调器执行弱磁功能，以调节压缩机的转速值。
采用本公开实施例提供的用于空调器的控制装置，使空调器在其运行阶段出现母线电压跌落时，可通过执行弱磁功能使压缩机持续稳定地运行，有利于提升直流空调器自清洁运行的稳定性。
结合图8所示，本公开实施例提供一种用于空调器的控制装置80，包括处理器(processor)100和存储器(memory)101。可选地，该装置还可以包括通信接口(Communication Interface)102和总线103。其中，处理器100、通信接口102、存储器101可以通过总线103完成相互间的通信。通信接口102可以用于信息传输。处理器100可以调用存储器101中的逻辑指令，以执行上述实施例的用于空调器的控制方法。
此外，上述的存储器101中的逻辑指令可以通过软件功能单元的形式实现并作为独立的产品销售或使用时，可以存储在一个计算机可读取存储介质中。
存储器101作为一种计算机可读存储介质，可用于存储软件程序、计算机可执行程序，如本公开实施例中的方法对应的程序指令/模块。处理器100通过运行存储在存储器101中的程序指令/模块，从而执行功能应用以及数据处理，即实现上述实施例中用于空调器的控制方法。
存储器101可包括存储程序区和存储数据区，其中，存储程序区可存储操作系统、至少一个功能所需的应用程序；存储数据区可存储根据终端设备的使用所创建的数据等。此外，存储器101可以包括高速随机存取存储器，还可以包括非易失性存储器。
