Embodiment 1

[0115] figure 2 It is a flowchart of a method for replacing a filter element according to an exemplary embodiment 1. Such as figure 2As shown, the method for replacing the filter element is used in equipment with filter elements, such as air conditioners, air purifiers, and automobiles. The application scenario of Embodiment 1 is: the preset parameter is air quality, and the air quality is divided into three levels, namely excellent, good, and poor; when the air quality is excellent, the preset life span is measured as T1; Comparison table, three levels of air quality are stored in the comparison table, and the preset loss coefficients corresponding to the three levels are K 优 、K 良 、K 差 , set K 优 = 1,K 良 =1.5,K 差 =2. The method in embodiment one comprises the steps:

[0116] In step S201, when the device is running, determine the level of the air quality under the current running condition, and count the running time of the device.

[0117] In step S202, according ...

Embodiment 2

[0124] image 3 It is a flowchart of a method for replacing a filter element according to a second exemplary embodiment. Such as image 3 As shown, the method for replacing the filter element is used in equipment with filter elements, such as air conditioners, air purifiers, and automobiles. The application scenario of the second embodiment is: the preset parameter is the ventilation rate, the ventilation rate is a specific value, and the standard ventilation rate V 标 In the case of , the measured preset life span is T2. The method in embodiment two comprises the steps:

[0125] In step S301, when the device is running, the value v of the ventilation rate under the current running condition is determined, and the running time of the device is counted.

[0126] In step S302, the value v of the determined ventilation volume and the standard ventilation volume V 标 The ratio obtained by the division is used as the weight coefficient.

[0127] Among them, the weight coefficie...

Embodiment 3

[0134] Figure 4 It is a flowchart of a method for replacing a filter element according to a third exemplary embodiment. Such as Figure 4 As shown, the method for replacing the filter element is used in equipment with filter elements, such as air conditioners, air purifiers, and automobiles. The application scenario of Embodiment 3 is: the preset parameters include: air quality, ventilation rate and purification rate; the air quality is divided into three levels, namely excellent, good and poor; the ventilation rate and purification rate are divided into specific values; When the air quality is excellent and the standard ventilation volume V 标 and the standard ventilation volume P 标 In the case of , the measured preset life span is T3; a comparison table is stored, which stores three levels of air quality and the preset loss coefficients corresponding to the three levels, which are K 优 、K 良 、K 差 , set K 优 = 1,K 良 =1.5,K 差 =2. The method in embodiment three comprises...

Abstract

The disclosure relates to a method and a device for changing a filter cartridge and aims at improving the filter cartridge change efficiency, lowering the labor cost and improving the accuracy in judging whether the filter cartridge is updated or not. The method is used for equipment with the filter cartridge and comprises the following steps: when the equipment runs, determining the reference value of a preset parameter under current running conditions and counting the running time of the equipment; updating the accumulative running time of the equipment according to the determined preset parameter reference value and the counted running time; judging whether the updated accumulative running time exceeds a preset service life or not; when the updated accumulative running time exceeds the preset service life, carrying out processing related to filter cartridge change. The disclosure can realize automation in judging whether the filter cartridge is changed or not, improve the operation efficiency and save the labor cost, and meanwhile, considers the influence of running environments when whether the filter cartridge is changed or not is judged and improves the judging accuracy.

Description

technical field [0001] The present disclosure relates to the technical field of intelligent control, in particular to a method and device for replacing a filter element. Background technique [0002] Currently, more and more devices have filters, such as air conditioners and air purifiers. The filter element in the equipment has a service life. If the filter element is used beyond the service life, harmful substances such as dust and bacteria will be blown into the air, causing harm to the human body. In the related art, the replacement of the filter element is carried out by manual inspection. The operator counts or estimates the running time, and roughly compares the running time with the life of the filter element given when the equipment leaves the factory to determine whether it is necessary to update the filter element. Alternatively, the staff regularly checks the state of the filter element, and judges whether the filter element needs to be replaced according to th...
