具体实施方式detailed description
应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
本发明提供一种空调器控制方法，参照图1，在本发明空调器控制方法第一实施例中，该空调器控制方法包括：The present invention provides an air conditioner control method. Referring to FIG. 1, in the first embodiment of the air conditioner control method of the present invention, the air conditioner control method includes:
步骤S10，当接收到预设的功耗等级限行指令时，获取所述功耗等级限行指令对应的限频电流值；Step S10, when receiving a preset power consumption level limit line instruction, acquiring a frequency limit current value corresponding to the power consumption level limit line instruction;
本发明实施例提供的空调器控制方法主要应用在定频空调中，用于对定频空调中压缩机的工作频率进行控制。The air conditioner control method provided by the embodiment of the invention is mainly applied to a fixed frequency air conditioner for controlling the working frequency of the compressor in the fixed frequency air conditioner.
上述预设的功耗等级限行指令可以由用户通过遥控发出，也可以通过上位机按照预设规则条件进行设置，当满足预设条件时，上位机主动向空调发送功耗等级限行指令。The preset power consumption level limit command may be sent by the user through remote control, or may be set according to a preset rule condition by the host computer. When the preset condition is met, the host computer actively sends a power consumption level limit command to the air conditioner.
上述限频电流值为空调在接收到上述功耗等级限行指令后，空调允许运行的最大电流值，即空调整机电流的上限值。具体地，可以设置不同级别的功耗等级限行指令以实现不同程度的限流，即不同级别的功耗等级限行指令对应不同大小的限频电流值。The above-mentioned frequency limiting current value is the maximum current value that the air conditioner is allowed to operate after receiving the above-mentioned power consumption level limit line command, that is, the upper limit value of the air conditioner current. Specifically, different levels of power consumption level limit instructions can be set to achieve different levels of current limiting, that is, different levels of power level limit line instructions correspond to different sizes of frequency limiting current values.
步骤S20，根据所述功耗等级限行指令获取空调当前的整机电流值；Step S20, obtaining a current current value of the air conditioner according to the power consumption level limit instruction;
本实施例中，在接收到上述功耗等级限行指令后，可以主动获取当前检 测到空调的整机电流值。具体地，在空调器中通常预设有电流检测模块实时检测空调当前运行状态下整机的电流值，当空调接收到上述功耗等级限行指令时，则获取该电流检测模块所检测的电流值。In this embodiment, after receiving the power consumption level limit command, the current check may be actively obtained. The current value of the air conditioner was measured. Specifically, the current detecting module is usually pre-configured in the air conditioner to detect the current value of the whole machine in the current running state of the air conditioner. When the air conditioner receives the power consumption level limit command, the current value detected by the current detecting module is obtained. .
步骤S30，判断所述当前的整机电流值是否大于所述限频电流值；Step S30, determining whether the current current value of the whole machine is greater than the current limit current value;
步骤S40，当所述当前的整机电流值大于所述限频电流值时，降低压缩机的频率，以使所述整机电流值小于或等于所述限频电流值。Step S40: When the current whole machine current value is greater than the frequency limit current value, reduce the frequency of the compressor so that the whole machine current value is less than or equal to the frequency limit current value.
在获取到上述整机电流值和限频电流值后，可以将该整机电流值和限频电流值进行比较，判断当前获取到空调的整机电流值是否大于限频电流值。若当前获取到的整机电流值小于或等于限频电流值，则表示空调当前工作状态下功耗较小，不需要进行限流；若当前获取到的整机电流值大于限频电流值，则表示空调当前工作状态下功耗较小，需要进行限流。在需要进行限流时，可以通过降低压缩机的频率从而降低空调整机的功耗，进而减小空调整机电流达到小于或等于限频电流值的范围。After obtaining the whole machine current value and the frequency limiting current value, the whole machine current value and the frequency limiting current value may be compared to determine whether the current current value of the current air conditioner obtained is greater than the limit current value. If the current current value of the whole machine is less than or equal to the current limit current value, it means that the power consumption of the air conditioner is small, and no current limit is needed; if the current current value of the whole machine is greater than the current limit current value, It means that the power consumption of the air conditioner is small under current working conditions, and current limiting is required. When the current limiting is required, the power consumption of the air conditioner can be reduced by reducing the frequency of the compressor, thereby reducing the range in which the air conditioner current reaches a value less than or equal to the frequency limiting current.
本发明实施例通过在空调接收到预设的功耗等级限行指令时，获取所述功耗等级限行指令对应的限频电流值；根据所述功耗等级限行指令获取空调当前的整机电流值；判断所述当前的整机电流值是否大于所述限频电流值；当所述当前的整机电流值大于所述限频电流值时，降低压缩机的频率，以使所述整机电流值小于或等于所述限频电流值。从而在定频空调中为满足功耗需求，自动对频率进行调整；因此在用电高峰期时，可以通过功耗限定对压缩机频率自动调整，以满足用电需求，从而可以达到空调错峰用电效果，提高了用电设备使用的可靠性。When the air conditioner receives the preset power consumption level limit line instruction, the embodiment obtains the frequency limit current value corresponding to the power consumption level limit line instruction; and obtains the current current value of the air conditioner according to the power consumption level limit line instruction. Determining whether the current current value of the whole machine is greater than the current limit current value; when the current current value of the whole machine is greater than the frequency limit current value, reducing the frequency of the compressor to make the current of the whole machine The value is less than or equal to the value of the current limit. Therefore, in the fixed-frequency air conditioner, the frequency is automatically adjusted to meet the power consumption requirement; therefore, during the peak power consumption period, the compressor frequency can be automatically adjusted by the power consumption limit to meet the power demand, thereby achieving the peak of the air conditioner. The power consumption effect improves the reliability of the use of electrical equipment.
进一步地，参照图2，基于本发明空调器控制方法第一实施例，在本发明空调器控制方法第二实施例中，该空调器控制方法还包括：The air conditioner control method further includes:
步骤S50，接收预设服务器通过互联网对预置区域内的空调发送的功耗等级限行指令。Step S50: Receive a power consumption level limit instruction sent by the preset server to the air conditioner in the preset area via the Internet.
本实施例中，上述预设服务器可以为一个总的服务器，用于管理与其相连的多个空调的工作。具体地，该服务器可以与多个空调器通过互联网连接，且每一个空调在上电时，可以向服务器上报当前的工作状态，以方便服务器进行查看以及管理。该服务器可以设置在供电局，由供电局对其供电小区内 的空调运行进行统一管理。例如，用户可以在该服务器上进行操作，选定需要进行功耗限定的小区或者空调，然后统一通过互联网的方式将上述功耗等级限行指令发送至各空调，以对空调的功耗进行限制。In this embodiment, the preset server may be a total server for managing the work of multiple air conditioners connected thereto. Specifically, the server can be connected to the plurality of air conditioners via the Internet, and each air conditioner can report the current working status to the server when the power is turned on, so as to facilitate the server to view and manage. The server can be set in the power supply bureau, and it is powered by the power supply bureau. The air conditioning operation is managed in a unified manner. For example, the user can operate on the server, select a cell or air conditioner that needs to be limited in power consumption, and then uniformly send the power consumption level limit command to each air conditioner through the Internet to limit the power consumption of the air conditioner.
进一步地，参照图3，基于本发明空调器控制方法第一实施例，在本发明空调器控制方法第三实施例中，上述步骤S10包括：Further, referring to FIG. 3, in the third embodiment of the air conditioner control method of the present invention, in the third embodiment of the air conditioner control method of the present invention, the above step S10 includes:
步骤S11，获取所述功耗等级限行指令中预设的等级降低比例；Step S11, acquiring a preset level reduction ratio in the power consumption level limit line instruction;
步骤S12，根据空调预设的标准功耗和额定电压计算标准工作电流，并根据所述标准工作电流以及等级降低比例计算所述限频电流值。Step S12: Calculate a standard operating current according to a standard power consumption and a rated voltage preset by the air conditioner, and calculate the frequency limiting current value according to the standard operating current and the level reduction ratio.
可以理解的是，上述功耗等级限行指令中包含的参数可以根据实际需要进行设置，例如可以直接是上述限频电流值，也可以是一个功耗降低的参数比值(即为上述等级降低比例)。本实施例中，优选地，该功耗等级限行指令中包含等级降低比例，例如该等级降低比例为50％、30％或20％等。以下将以等级降低比例是50％为例进行详细说明。It can be understood that the parameters included in the power consumption level limit command may be set according to actual needs, for example, may be directly the above-mentioned frequency limit current value, or may be a power consumption reduced parameter ratio (ie, the above-mentioned level reduction ratio) . In this embodiment, preferably, the power consumption level limit line instruction includes a level reduction ratio, for example, the level reduction ratio is 50%, 30%, or 20%. The following will be described in detail by taking the level reduction ratio as 50% as an example.
具体地，每个空调在出厂时均设置有标准功耗以及额定工作电压，对于不同的定频空调对应的标准功耗不一致。且该标准功耗作为空调的参数存储在预置的存储芯片中，在需要计算上述限频电流值时，或者接收到上述功耗等级限行指令时，可以首先读取该存储芯片中存储的标准功耗，然后根据标准功耗与额定电压的比值计算得到标准工作电流；接着再计算标准工作电流与等级降低比例的乘积得到需要限定的限频电流值。可以理解的是，对于上述标准功耗也可以通过各空调的型号通过互联网大数据进行查找获得。此外对于各空调计算限频电流值的操作还可以在服务器中完成。Specifically, each air conditioner is set with standard power consumption and rated working voltage at the factory, and the standard power consumption corresponding to different fixed frequency air conditioners is inconsistent. And the standard power consumption is stored in the preset memory chip as a parameter of the air conditioner. When the frequency limit current value needs to be calculated, or when the power consumption level limit command is received, the standard stored in the memory chip may be read first. The power consumption is then calculated according to the ratio of the standard power consumption to the rated voltage. Then, the product of the standard operating current and the level reduction ratio is calculated to obtain a limited current value to be limited. It can be understood that the above standard power consumption can also be obtained through Internet big data search by the model of each air conditioner. In addition, the operation of calculating the frequency-limiting current value for each air conditioner can also be performed in the server.
在本实施例中，以上述标准功耗是1000W、标准电压是230V和等级降低比例是50％为例进行说明。则上述限频电流值＝1000W÷230V*50％＝2.17A；此时，若空调当前的整机电流为3A，则需要降低压缩机的频率从而满足功耗需求；若空调当前的整机电流为2.5A，则空调按照当前状态继续运行。In the present embodiment, the above-described standard power consumption is 1000 W, the standard voltage is 230 V, and the level reduction ratio is 50% as an example. Then the above-mentioned frequency limiting current value=1000W÷230V*50%=2.17A; at this time, if the current current of the air conditioner is 3A, the frequency of the compressor needs to be reduced to meet the power consumption requirement; if the current current of the air conditioner is current At 2.5A, the air conditioner continues to operate according to the current state.
由于根据每一个空调自身的标准功耗和额定功耗参数计算限频电流，从而可以根据空调的不同性能对空调限频的范围进行对应调整，以保证空调运行的可靠性。 Since the current limit current is calculated according to the standard power consumption and the rated power consumption parameter of each air conditioner, the range of the air conditioner frequency limit can be adjusted according to different performances of the air conditioner to ensure the reliability of the air conditioner operation.
进一步地，参照图4，基于本发明空调器控制方法第一实施例，在本发明空调器控制方法第四实施例中，上述步骤S40包括：Further, referring to FIG. 4, in the fourth embodiment of the air conditioner control method of the present invention, the above step S40 includes:
步骤S41，当所述当前的整机电流值大于所述限频电流值时，根据预设的压缩机频率降低等级参数降低所述压缩机的频率；Step S41, when the current whole machine current value is greater than the current limit current value, reducing the frequency of the compressor according to a preset compressor frequency reduction level parameter;
步骤S42，在降低压缩机频率预置时间后，再次获取所述空调当前的整机电流值，并判断再次获取的所述当前的整机电流值是否大于所述限频电流值。Step S42, after the preset time of the compressor frequency is decreased, the current current value of the air conditioner is obtained again, and it is determined whether the current current value obtained again is greater than the current limit current value.
本实施例中，对于压缩机频率降低的方式可以根据实际需要进行设置，例如，可以每次降低固定频率值，例如10Hz；也可以按照固定等级进行频率降低，例如A等级为70Hz、B等级为60Hz、C等级为55Hz、D等级为50Hz，此时，可以逐步降低压缩机运行频率的等级。在每一次降低压缩机频率或者每两次降低压缩机频率后，需要经过预置时间，再次获取空调当前的整机电流值，判断在降低压缩机频率后整机电流是否满足小于或等于上述限频电流值的条件，若满足，则不需要再次进行降频调整；若不满足，仍然需要进行再次降频处理，直到当前的整机电流值小于或等于上述限频电流值为止。In this embodiment, the method for reducing the frequency of the compressor may be set according to actual needs. For example, the fixed frequency value may be lowered every time, for example, 10 Hz; or the frequency may be reduced according to a fixed level, for example, the A level is 70 Hz, and the B level is 60Hz, C level is 55Hz, D level is 50Hz, at this time, the level of compressor operating frequency can be gradually reduced. After reducing the compressor frequency or reducing the compressor frequency every time, it is necessary to go through the preset time to obtain the current current value of the air conditioner again, and determine whether the current of the whole machine meets the above limit after reducing the compressor frequency. If the condition of the frequency current value is satisfied, it is not necessary to perform the down-conversion adjustment again; if it is not satisfied, the frequency-reduction process still needs to be performed until the current machine current value is less than or equal to the above-mentioned frequency-limiting current value.
进一步地，参照图5，基于本发明空调器控制方法第一实施例，在本发明空调器控制方法第五实施例中，上述步骤S40之前还包括：Further, referring to FIG. 5, based on the first embodiment of the air conditioner control method of the present invention, in the fifth embodiment of the air conditioner control method of the present invention, before the step S40, the method further includes:
步骤S60，判断所述压缩机的频率是否小于预设频率；若是，则执行步骤S70，若否，则执行步骤S40；Step S60, it is determined whether the frequency of the compressor is less than the preset frequency; if so, step S70 is performed, and if not, step S40 is performed;
步骤S70，控制所述空调停止运行。Step S70, controlling the air conditioner to stop running.
可以理解的是，在空调中压缩机通常设有最小运行频率，以保证空调运行的可靠性，具体地，每一空调对应的最小运行频率可以根据实际情况进行设置，在此不做进一步地限定。本实施例中，优选地，上述预设频率略大于该最小运行频率。即，当压缩机以该最小运行频率运行时，若整机电流值仍然大于上述限频电流值，则控制空调停止运行。It can be understood that the compressor is usually provided with a minimum operating frequency in the air conditioner to ensure the reliability of the air conditioning operation. Specifically, the minimum operating frequency corresponding to each air conditioner can be set according to actual conditions, and is not further limited herein. . In this embodiment, preferably, the preset frequency is slightly larger than the minimum operating frequency. That is, when the compressor is operated at the minimum operating frequency, if the current value of the whole machine is still greater than the above-mentioned limited current value, the air conditioner is controlled to stop running.
进一步地，本发明还提供一种空调器控制装置，参照图6，在本发明空调器控制装置第一实施例中，该空调器控制装置包括：Further, the present invention further provides an air conditioner control apparatus.

Specifically, different levels of power consumption level limit instructions can be set to achieve different levels of current limiting, that is, different levels of power level limit line instructions correspond to different sizes of frequency limiting current values.

Specifically, the current detecting module is usually pre-configured in the air conditioner to detect the current value of the whole machine in the current running state of the air conditioner. When the air conditioner receives the power consumption level limit command, the current value detected by the current detecting module is obtained. .

在获取到上述整机电流值和限频电流值后，可以将该整机电流值和限频电流值进行比较，判断当前获取到空调的整机电流值是否大于限频电流值。若当前获取到的整机电流值小于或等于限频电流值，则表示空调当前工作状态下功耗较小，不需要进行限流；若当前获取到的整机电流值大于限频电流值，则表示空调当前工作状态下功耗较小，需要进行限流。在需要进行限流时，可以通过降低压缩机的频率从而降低空调整机的功耗，进而减小空调整机电流达到小于或等于限频电流值的范围。After obtaining the whole machine current value and the frequency limiting current value, the whole machine current value and the frequency limiting current value may be compared to determine whether the current current value of the current air conditioner obtained is greater than the limit current value. If the current current value of the whole machine is less than or equal to the current limit current value, it means that the power consumption of the air conditioner is small, and no current limit is needed; if the current current value of the whole machine is greater than the current limit current value, It means that the power consumption of the air conditioner is small under current working conditions, and current limiting is required. When the current limiting is required, the power consumption of the air conditioner can be reduced by reducing the frequency of the compressor, thereby reducing the range in which the air conditioner current reaches a value less than or equal to the frequency limiting current.

Determining whether the current current value of the whole machine is greater than the current limit current value; when the current current value of the whole machine is greater than the frequency limit current value, reducing the frequency of the compressor, so that The whole machine current value is less than or equal to the frequency limit current value. Therefore, in the fixed-frequency air conditioner, the frequency is automatically adjusted to meet the power consumption requirement; therefore, during the peak power consumption period, the compressor frequency can be automatically adjusted by the power consumption limit to meet the power demand, thereby achieving the peak of the air conditioner.

可以理解的是，上述功耗等级限行指令中包含的参数可以根据实际需要进行设置，例如可以直接是上述限频电流值，也可以是一个功耗降低的参数比值(即为上述等级降低比例)。本实施例中，优选地，该功耗等级限行指令中包含等级降低比例，例如该等级降低比例为50％、30％或20％等。以下将以等级降低比例是50％为例进行详细说明。It can be understood that the parameters included in the power consumption level limit command may be set according to actual needs, for example, may be directly the above-mentioned frequency limit current value, or may be a power consumption reduced parameter ratio (ie, the above-mentioned level reduction ratio) . In this embodiment, preferably, the power consumption level limit line instruction includes a level reduction ratio, for example, the level reduction ratio is 50%, 30%, or 20%. The following will be described in detail by taking the level reduction ratio as 50% as an example.
具体地，每个空调在出厂时均设置有标准功耗以及额定工作电压，对于不同的定频空调对应的标准功耗不一致。且该标准功耗作为空调的参数存储 在预置的存储芯片中，在需要计算上述限频电流值时，或者接收到上述功耗等级限行指令时，可以首先读取该存储芯片中存储的标准功耗，然后根据标准功耗与额定电压的比值计算得到标准工作电流；接着再计算标准工作电流与等级降低比例的乘积得到需要限定的限频电流值。可以理解的是，对于上述标准功耗也可以通过各空调的型号通过互联网大数据进行查找获得。此外对于各空调计算限频电流值的操作还可以在服务器中完成。Specifically, each air conditioner is set with standard power consumption and rated working voltage at the factory, and the standard power consumption corresponding to different fixed frequency air conditioners is inconsistent. And the standard power consumption is stored as a parameter of the air conditioner. In the preset memory chip, when it is required to calculate the above-mentioned frequency limiting current value, or when receiving the above power consumption level limit line instruction, the standard power consumption stored in the memory chip may be read first, and then according to standard power consumption and rated The ratio of the voltage is calculated to obtain the standard operating current; then the product of the standard operating current and the level reduction ratio is calculated to obtain the limited current value to be limited. It can be understood that the above standard power consumption can also be obtained through Internet big data search by the model of each air conditioner. In addition, the operation of calculating the frequency-limiting current value for each air conditioner can also be performed in the server.
在本实施例中，以上述标准功耗是1000W、标准电压是230V和等级降低比例是50％为例进行说明。则上述限频电流值＝1000W÷230V*50％＝2.17A；此时，若空调当前的整机电流为3A，则需要降低压缩机的频率从而满足功耗需求；若空调当前的整机电流为2.5A，则空调按照当前状态继续运行。In the present embodiment, the above-described standard power consumption is 1000 W, the standard voltage is 230 V, and the level reduction ratio is 50% as an example. Then the above-mentioned frequency limiting current value=1000W÷230V*50%=2.17A; at this time, if the current current of the air conditioner is 3A, the frequency of the compressor needs to be reduced to meet the power consumption requirement; if the current current of the air conditioner is current At 2.5A, the air conditioner continues to operate according to the current state.
由于根据每一个空调自身的标准功耗和额定功耗参数计算限频电流，从而可以根据空调的不同性能对空调限频的范围进行对应调整，以保证空调运行的可靠性。Since the current limit current is calculated according to the standard power consumption and the rated power consumption parameter of each air conditioner, the range of the air conditioner frequency limit can be adjusted according to different performances of the air conditioner to ensure the reliability of the air conditioner operation.
进一步地，参照图9，基于本发明空调器控制装置第一实施例，在本发明空调器控制装置第四实施例中，该调整模块40包括：Further, referring to FIG. 9, according to the first embodiment of the air conditioner control device of the present invention, in the fourth embodiment of the air conditioner control device of the present invention, the adjustment module 40 includes:

第二获取单元42，用于在降低压缩机频率预置时间后，再次获取所述空调当前的整机电流值，并判断再次获取的所述当前的整机电流值是否大于所述限频电流值。The second obtaining unit 42 is configured to acquire the current current value of the air conditioner again after reducing the preset time of the compressor frequency, and determine whether the current current value of the current whole machine acquired is greater than the current limiting current. value.
本实施例中，对于压缩机频率降低的方式可以根据实际需要进行设置，例如，可以每次降低固定频率值，例如10Hz；也可以按照固定等级进行频率降低，例如A等级为70Hz、B等级为60Hz、C等级为55Hz、D等级为50Hz，此时，可以逐步降低压缩机运行频率的等级。在每一次降低压缩机频率或者每两次降低压缩机频率后，需要经过预置时间，再次获取空调当前的整机电流值，判断在降低压缩机频率后整机电流是否满足小于或等于上述限频电流值的条件，若满足，则不需要再次进行降频调整；若不满足，仍然需要进行再次降频处理，直到当前的整机电流值小于或等于上述限频电流值为止。 In this embodiment, the method for reducing the frequency of the compressor may be set according to actual needs. For example, the fixed frequency value may be lowered every time, for example, 10 Hz; or the frequency may be reduced according to a fixed level, for example, the A level is 70 Hz, and the B level is 60Hz, C level is 55Hz, D level is 50Hz, at this time, the level of compressor operating frequency can be gradually reduced. After reducing the compressor frequency or reducing the compressor frequency every time, it is necessary to go through the preset time to obtain the current current value of the air conditioner again, and determine whether the current of the whole machine meets the above limit after reducing the compressor frequency. If the condition of the frequency current value is satisfied, it is not necessary to perform the down-conversion adjustment again; if it is not satisfied, the frequency-reduction process still needs to be performed until the current machine current value is less than or equal to the above-mentioned frequency-limiting current value.
进一步地，参照图10，基于本发明空调器控制装置第一实施例，在本发明空调器控制装置第五实施例中，上述空调器控制装置还包括：The air conditioner control device further includes:

可以理解的是，在空调中压缩机通常设有最小运行频率，以保证空调运行的可靠性，具体地，每一空调对应的最小运行频率可以根据实际情况进行设置，在此不做进一步地限定。本实施例中，优选地，上述预设频率略大于该最小运行频率。即，当压缩机以该最小运行频率运行时，若整机电流值仍然大于上述限频电流值，则控制空调停止运行。It can be understood that the compressor is usually provided with a minimum operating frequency in the air conditioner to ensure the reliability of the air conditioning operation. Specifically, the minimum operating frequency corresponding to each air conditioner can be set according to actual conditions, and is not further limited herein. . In this embodiment, preferably, the preset frequency is slightly larger than the minimum operating frequency. That is, when the compressor is operated at the minimum operating frequency, if the current value of the whole machine is still greater than the above-mentioned limited current value, the air conditioner is controlled to stop running.
