The system includes an air conditioner 1, an APP terminal 2, and a server 3. Among them, the APP is installed on a smart terminal (such as a smart phone, a tablet computer, etc.).

One APP account can be bound to the unique identifier of at least one air conditioner, and the APP terminal 2 will carry the unique identifier of the air conditioner when communicating with the server 3.

空调器1将风道内的温度、湿度和当前图像发送至APP端2。APP端2将接收到的风道内的温度、湿度和当前图像上传至服务器3；The air conditioner 1 sends the temperature, humidity and current image in the air duct to the APP terminal 2. APP 2 uploads the received temperature, humidity and current image in the air duct to server 3;
服务器3判断风道内的温度和湿度满足细菌快速滋生环境参数时，对比当前图像和风道的初始图像确定风道的内壁存在异物时，控制空调器制热对风道内的细菌进行灭活。When the server 3 judges that the temperature and humidity in the air duct meet the environment parameters for rapid growth of bacteria, it compares the current image with the initial image of the air duct to determine that there is foreign matter on the inner wall of the air duct, and controls the air conditioner to heat the air duct to inactivate the bacteria in the air duct.
下面将结合图2对服务器侧执行的空调器控制方法进行详细说明，如图2所示，空调器控制控制方法包括：The air conditioner control method executed on the server side will be described in detail below with reference to FIG. 2. As shown in FIG. 2, the air conditioner control method includes:
S110，获取空调器内风道的当前环境参数。S110: Acquire current environmental parameters of the air duct in the air conditioner.
风道的环境参数包括风道内的温度和湿度，空调器将风道内的温度和湿度发送至智能终端的APP，再由APP上传至服务器中。The environmental parameters of the air duct include the temperature and humidity in the air duct. The air conditioner sends the temperature and humidity in the air duct to the APP of the smart terminal, and then the APP uploads it to the server.
S120，判断当前环境参数是否满足细菌快速滋生环境参数；如果是，则执行S130；如果否，则不进行操作，即当前流程结束。In S120, it is judged whether the current environment parameter meets the environment parameter for rapid growth of bacteria; if yes, execute S130; if not, no operation is performed, that is, the current process ends.
以霉菌为例，当环境的温度和湿度达到一定条件时，霉菌才会快速生长，此时的温度和湿度即细菌快速滋生环境参数。如果判定风道内的环境参数符合霉菌的快速滋生条件则需要进一步根据风道内的图像判断风道内是否已经滋生霉菌。Take mold as an example. When the temperature and humidity of the environment reach a certain condition, the mold will grow rapidly. The temperature and humidity at this time are the environmental parameters for rapid growth of bacteria. If it is determined that the environmental parameters in the air duct meet the conditions for rapid growth of mold, it is necessary to further determine whether mold has grown in the air duct based on the image in the air duct.
S130，获取空调器内风道的当前图像。S130: Acquire a current image of the air duct in the air conditioner.
空调器的风道内设置有图像传感器用于采集风道内的图像，空调器将风道内的图像发送至智能终端的APP，APP将该图像发送至服务器。An image sensor is installed in the air duct of the air conditioner to collect images in the air duct. The air conditioner sends the image in the air duct to the APP of the smart terminal, and the APP sends the image to the server.
S140，对比当前图像及空调器内风道的初始图像，判断风道的内壁是否存在异物；如果是，则执行S150。如果否，则执行S160。S140: Compare the current image with the initial image of the air duct in the air conditioner to determine whether there is a foreign object on the inner wall of the air duct; if so, execute S150. If not, execute S160.
初始图像是空调器初次安装时获得的风道内的图像，例如，当空调器初次安装好后上电后图像传感器采集风道内的图像。初始图像会由空调器发送至APP，再由APP上传并存储至服务器中。The initial image is the image in the air duct obtained when the air conditioner is installed for the first time. For example, when the air conditioner is first installed and powered on, the image sensor collects the image in the air duct. The initial image will be sent by the air conditioner to the APP, and then uploaded by the APP and stored in the server.
之后，只要空调器处于上电状态即可按照指定的采集周期采集风道内的图像，即风道内的当前图像。After that, as long as the air conditioner is in the power-on state, the image in the air duct can be collected according to the specified collection period, that is, the current image in the air duct.
服务器接收到风道的当前图像后与初始图像进行对比，以判断风道内是否存在异物，如果当前图像与初始图像之间存在明显差别则确定风道内存在异物，如果当前图像与初始图像之间不存在明显差别则确定风道内不存在异物。The server compares the current image of the air duct with the initial image to determine whether there is a foreign object in the air duct. If there is a significant difference between the current image and the initial image, it determines that there is a foreign object in the air duct. If there is a significant difference, it is determined that there is no foreign body in the air duct.
在本申请一种可能的实现方式中，如图3所示，服务器对比风道的当前图像与初始图像的过程可以包括以下步骤：In a possible implementation of the present application, as shown in FIG. 3, the process of comparing the current image of the air duct with the initial image by the server may include the following steps:
S141，服务器从本地读取空调器初次上电时获得的风道内的初始图像。S141: The server reads locally the initial image in the air duct obtained when the air conditioner is first powered on.
可以通过空调器的唯一标识从本地查询得到该空调器的风道的初始图像。The initial image of the air duct of the air conditioner can be obtained from a local query through the unique identification of the air conditioner.
S142，将初始图像和当前图像均进行图像分割得到多个图像块。S142: Perform image segmentation on both the initial image and the current image to obtain multiple image blocks.
S143，逐一比较初始图像和当前图像中同一位置的图像块包含的图像内容是否相同。S143: Compare one by one whether the image content contained in the image block at the same position in the initial image and the current image is the same.
S144，当图像内容相同的图像块的数量低于预设比例，确定初始图像和当前图像存在明显差异，并确定风道的内壁存在异物。S144: When the number of image blocks with the same image content is lower than a preset ratio, it is determined that there is a significant difference between the initial image and the current image, and it is determined that there is a foreign object on the inner wall of the air duct.
预设比例可以根据实际需求设定，例如，80％，如果相同的图像块数量小于80％，则表明两个图像存在明显差异，进而确定风道内存在异物，如，霉菌。The preset ratio can be set according to actual needs, for example, 80%. If the number of the same image blocks is less than 80%, it indicates that there is a significant difference between the two images, and then it is determined that there are foreign objects, such as molds, in the air duct.
通常情况下，如果风道内存在非细菌类异物，如PU衬垫等，这些异物的重量通常较轻，当空调器运行时这些异物就会被风吹出风道。而霉菌等细菌会牢牢粘在风道表面，不会轻易被风吹走，因此，可以在空调运行后采集风道内的图像判断风道内是否仍存在异物则确定风道内的异物是细菌。Normally, if there are non-bacterial foreign objects in the air duct, such as PU liners, the weight of these foreign objects is usually light, and these foreign objects will be blown out of the air duct when the air conditioner is running. Bacteria such as molds will stick to the surface of the air duct firmly and will not be easily blown away by the wind. Therefore, after the air conditioner is running, the images in the air duct can be collected to determine whether there are foreign objects in the air duct, and the foreign objects in the air duct can be determined to be bacteria.
S145，当图像内容相同的图像块的数量大于或等于预设比例，确定除湿图像和当前图像不存在明显差异，并确定风道的内壁不存在异物。S145: When the number of image blocks with the same image content is greater than or equal to the preset ratio, it is determined that there is no significant difference between the dehumidified image and the current image, and it is determined that there is no foreign matter on the inner wall of the air duct.
S150，控制空调器制热对风道内的细菌进行灭活。S150, controlling the heating of the air conditioner to inactivate bacteria in the air duct.
如果根据风道内的图像对比判定风道内存在异物，则控制空调器制热，压缩机高频运转，室内机风扇不运转，同时，关闭导风板，使风道内的温度达到细菌灭活温度(例如， 60℃及以上)，并在预设时长内保持该温度，例如，20min，以实现对风道内的霉菌灭活。If it is determined that there are foreign objects in the air duct based on the image comparison in the air duct, the air conditioner is controlled to heat, the compressor runs at high frequency, the indoor unit fan does not run, and at the same time, the air deflector is closed to make the temperature in the air duct reach the bacteria inactivation temperature ( For example, 60°C and above), and maintain the temperature for a preset period of time, for example, 20 minutes, to achieve the inactivation of molds in the air duct.
S160，控制空调器进行除湿，当风道内的环境参数达到细菌不滋生的环境参数时，控制空调器停止除湿，并开启制热。S160: Control the air conditioner to perform dehumidification. When the environmental parameters in the air duct reach the environmental parameters where bacteria do not breed, control the air conditioner to stop dehumidification and start heating.
如果风道内的图像对比判定风道内不存在衣物，则控制空调器进行除湿，且在风道内的湿度在一定湿度范围内(例如，40％～55％)，且风道内的温度小于第二预设温度时，确定风道的环境参数达到细菌不滋生的环境参数时，停止除湿，然后，开启制热，以使风道内保持干燥。If the image comparison in the air duct determines that there is no clothing in the air duct, the air conditioner is controlled to dehumidify, and the humidity in the air duct is within a certain humidity range (for example, 40% to 55%), and the temperature in the air duct is less than the second predetermined When setting the temperature, when it is determined that the environmental parameters of the air duct reach the environmental parameters that bacteria do not breed, stop the dehumidification, and then turn on the heating to keep the air duct dry.
本实施例提供的空调器控制方法，当检测到空调器内的风道的当前环境参数满足细菌快速滋生环境参数时，获取风道的当前图像，并将当前图像与风道的原始图像进行比较，判断风道内是否存在异物，若确定风道内存在异物则控制空调器制热以对风道内的霉菌进行灭活。若风道内不存在异物则控制空调器进行除湿，直到风道内的环境参数达到不滋生细菌的环境参数停止除湿并开启制热，避免风道内滋生细菌。该方案在风道内存在细菌时通过制热消除细菌，当风道内不存在细菌但环境参数极易滋生细菌时，使空调器先除湿后制热避免细菌滋生。空调处于上电状态即可实施该方案，从而实现全应用场景下防止细菌滋生。In the air conditioner control method provided in this embodiment, when it is detected that the current environmental parameters of the air duct in the air conditioner meet the environmental parameters for rapid bacterial growth, the current image of the air duct is acquired, and the current image is compared with the original image of the air duct , Determine whether there are foreign objects in the air duct, and if it is determined that there are foreign objects in the air duct, control the heating of the air conditioner to inactivate the mold in the air duct. If there is no foreign matter in the air duct, the air conditioner is controlled to dehumidify until the environmental parameters in the air duct reach the environmental parameters that do not breed bacteria. The dehumidification is stopped and the heating is turned on to avoid the growth of bacteria in the air duct. This solution eliminates bacteria by heating when there are bacteria in the air duct. When there is no bacteria in the air duct but the environmental parameters are prone to bacteria, the air conditioner is dehumidified and then heated to avoid bacterial growth. This solution can be implemented when the air conditioner is powered on, so as to prevent the growth of bacteria in all application scenarios.

如果湿度大于等于第一预设湿度且温度大于等于第一预设温度，则执行S122；If the humidity is greater than or equal to the first preset humidity and the temperature is greater than or equal to the first preset temperature, execute S122;
如果湿度大于第一预设湿度且温度小于第一预设温度，则执行S123；If the humidity is greater than the first preset humidity and the temperature is less than the first preset temperature, execute S123;

参见图5，湿度大于第一预设湿度(如55％)的区域为霉菌滋生区域；湿度小于第二预设湿度(如40％)的区域为流感病毒滋生区域。因此，在控制空调器除湿时，能够抑制霉菌滋生同时还不能为流感病毒创造滋生环境，因此，风道内的湿度控制在40％以上。Referring to FIG. 5, the area where the humidity is greater than the first preset humidity (such as 55%) is a mold breeding area; the area where the humidity is less than the second preset humidity (such as 40%) is the influenza virus breeding area. Therefore, when controlling the dehumidification of the air conditioner, the growth of molds can be suppressed and the breeding environment for influenza viruses cannot be created. Therefore, the humidity in the air duct is controlled above 40%.
在不同的温度范围内，霉菌滋生区域又分为霉菌快速滋生区域、霉菌低水平滋生区域和霉菌不滋生区域。其中，环境的湿度大于55％且温度大于27℃的区域是霉菌快速滋生的区域。湿度大于55％，温度小于27℃的区域为霉菌低水平滋生区域。当湿度小于55％且大于40％，同时，温度小于27℃的区域是不滋生霉菌的区域。In different temperature ranges, the mold growth area is divided into the mold rapid growth area, the mold low-level growth area and the mold no growth area. Among them, the area where the humidity of the environment is greater than 55% and the temperature is greater than 27°C is the area where molds grow rapidly. The area where the humidity is greater than 55% and the temperature is less than 27°C is a low-level mold breeding area. When the humidity is less than 55% and greater than 40%, at the same time, the area where the temperature is less than 27°C is the area where mold does not grow.
S122，确定风道的当前环境参数满足细菌快速滋生环境参数。S122: Determine that the current environmental parameters of the air duct meet the environmental parameters for rapid growth of bacteria.
S123，确定风道的当前环境参数不满足细菌快速滋生环境参数。S123: Determine that the current environmental parameters of the air duct do not meet the environmental parameters for rapid bacterial growth.
在本申请的另一种应用场景中，在检测到风道内的环境处于细菌快速滋生环境参数范围内，控制空调器进行除湿后，如果检测到风道内的湿度小于第一预设湿度且大于或等于第二预设湿度，同时，风道内的温度小于第二预设温度，则确定风道内的环境参数达到细菌不滋生的环境参数。其中，第二预设温度小于第一预设温度。In another application scenario of the present application, after it is detected that the environment in the air duct is within the range of environmental parameters for rapid bacterial growth, after controlling the air conditioner to dehumidify, if it is detected that the humidity in the air duct is less than the first preset humidity and greater than or If the humidity is equal to the second preset humidity, and at the same time, the temperature in the air duct is less than the second preset temperature, it is determined that the environmental parameters in the air duct reach the environmental parameters that bacteria do not breed. Wherein, the second preset temperature is less than the first preset temperature.
例如，如图5所示，当湿度介于40％～55％之间，同时，温度小于24℃时，霉菌处于不滋生区域。For example, as shown in Figure 5, when the humidity is between 40% and 55% and the temperature is less than 24°C, molds are in a non-growth area.
本实施例根据霉菌滋生与环境的温湿度之间的关系，确定风道当前环境是细菌快速滋生水平还是低水平滋生区域，进一步根据判定结果执行不同的空调控制策略，最终实现将空调器风道的环境参数调整至不滋生霉菌的水平，避免霉菌滋生。In this embodiment, according to the relationship between the growth of mold and the temperature and humidity of the environment, it is determined whether the current environment of the air duct is a rapid growth level of bacteria or a low-level breeding area, and different air conditioning control strategies are further implemented according to the determination result, and finally the air duct of the air conditioner Adjust the environmental parameters to a level that does not breed mold to avoid mold growth.
