[0029] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0030] See also Figures 1 to 6 According to an embodiment of the present invention, a filtering system is provided, comprising: a monitoring module 1, the monitoring module 1 is used to monitor the blockage of the filter 10 of the air conditioning system; a replacement module, the replacement module replaces the filter 10 according to the blockage of the filter 10; a cleaning module 3, the cleaning module 3 is used to clean the replaced filter 10; and a drying module 4, the drying module 4 is used to dry the cleaned filter 10. With the above configuration, when the filter 10 of the air conditioning system is dirty and blocked, it can be quickly identified and replaced, and the replaced filter 10 can be processed for next use, saving manpower and solving the technical problem of high cost of replacing the filter of the air conditioning system.

[0031] In the filtration system of this embodiment, see Figure 2 The monitoring module 1 includes: a pressure monitoring module 11, which is used to detect the pressure on the two opposite sides of the filter 10, so as to judge the blockage condition of the filter 10 according to the pressure difference on the two opposite sides of the filter 10.

[0032] Specifically, when the pressure difference is too large, it indicates that the filter 10 is seriously clogged, which affects the passage of the fluid through the filter 10. At this time, the filter 10 needs to be replaced to prevent the filter 10 from being clogged and affecting the filtering function.

[0033] See also Figure 1 In the filtering system of this embodiment, the monitoring module 1 includes: an image module 12, the image module 12 includes a camera for capturing an image of the filter 10, and the image module 12 compares the captured image of the filter 10 with a preset image to determine the blockage condition of the filter 10.

[0034] Specifically, high-definition three-dimensional cameras are installed before and after the filter 10, and a preset three-dimensional image of the filter 10 when it is clean is displayed. When the difference between the three-dimensional image of the filter 10 and the preset image reaches a preset value, the system determines that the filter 10 is blocked. In this way, the state of the filter 10 can be detected in real time, which is convenient for control.

[0035] In the filtering system of this embodiment, the filtering system includes: a first filtering station and a second filtering station, both of which are used to place the filter net 10; a monitoring module 1 is used to monitor the blockage of the filter net 10 on the first filtering station and the second filtering station; and a replacement module is used to disassemble and install the filter net 10 on the first filtering station and the second filtering station.

[0036] Specifically, the air inlet is designed to have two filter installation locations, that is, the spare filter is directly installed at the vacant installation location, so the filter can be replaced without shutting down the unit.

[0037] In the filtration system of this embodiment, see Figure 3 The cleaning module 3 includes: a cleaning pool 31, which is used to collect condensed water generated by the air conditioning system; a water inlet and a drain are provided on the cleaning pool 31; a water level sensor 32 is provided in the cleaning pool 31, and the cleaning module 3 replenishes cleaning water into the cleaning pool 31 through the water inlet or drains the water in the cleaning pool 31 through the drain according to the water level detected by the water level sensor 32. In this way, the condensed water generated by the air conditioning system can save resources, and when the condensed water is insufficient or excessive, the cleaning operation can be ensured to proceed normally by replenishing water or draining water.

[0038] See also Figure 4 In the filter system of this embodiment, the drying module 4 is arranged at the heater of the air conditioning system, and the drying module 4 uses the heat of the heater to dry the filter 10. In this way, the heat generated by the air conditioning system itself is used for drying, which saves energy.

[0039] The air conditioning system of this embodiment includes a filtering system, and the filtering system is the filtering system mentioned above.

[0040] The air conditioning system of this embodiment adopts the above-mentioned filtering system, which can monitor and automatically replace the filter in real time, and use the resources generated by the unit itself to clean and dry the filter, saving resources, reducing manual operations, and eliminating the need for shutdown for maintenance.

[0041] See also Figure 5 , Figure 6 The control method of this embodiment is applicable to the above-mentioned filtering system, and the control method includes: the monitoring module 1 monitors whether the filter 10 is blocked in real time; when the current filter 10 is detected to be blocked, the spare filter 10 is used to replace the current filter 10; the removed filter 10 is transferred to the cleaning module 3 for cleaning; the cleaned filter 10 is transferred to the drying module 4 for drying. In this way, the filter can be monitored in real time and automatically replaced, and the filter can be cleaned and dried using the resources generated by the unit itself, saving resources, reducing manual operations, and eliminating the need for shutdown and maintenance.

[0042] In the control method of this embodiment, see Figure 5 , Figure 6 The method for monitoring whether the filter 10 is clogged includes: setting cameras on opposite sides of the filter 10; presetting an image of the filter 10 when it is clean; when the difference between the monitored image of the filter 10 and the preset image reaches a preset value, determining that the filter 10 is clogged.

[0043] In this way, the dirtiness and blockage of the filter 10 can be identified remotely without affecting the normal operation of the equipment.

[0044] See also Figure 5 , Figure 6 In the control method of the present embodiment, the method for judging whether the difference between the image of the filter 10 and the preset image reaches the preset value includes: segmenting the monitored image of the filter 10 to obtain the area with dust on the filter 10 at this time; calculating and analyzing the volume of each dust area, and summing the volumes of each dust area; comparing the summed structure with the volume of the original entire image, and when the summed value exceeds the preset value, it is considered that the filter 10 is blocked at this time.

[0045] Specifically, the real-time image is compared with the preset image, the filter image is segmented, the area with dust on the filter is obtained, the volume of each dust area is calculated and analyzed, and then the sum is taken and compared with the volume of the original entire image. When the value exceeds 20%, it is considered that the filter is clogged.

[0046] In the control method of this embodiment, see Figure 5 , Figure 6 The method for cleaning the filter 10 includes: replenishing or discharging the cleaning water in the cleaning pool 31 of the cleaning module 3 until the water level in the cleaning pool 31 reaches the requirement; placing the filter 10 in the cleaning pool 31 for cleaning; after cleaning, detecting whether the cleanliness of the water in the cleaning pool 31 exceeds a preset value, if it exceeds the preset value, discharging the cleaning water in the cleaning pool 31; if it does not exceed the preset value, storing the cleaning water in the cleaning pool 31 for standby use; wherein, water cleanliness = (weight of water in the cleaning pool 31 after this cleaning - weight of water in the cleaning pool 31 before the first cleaning) / weight of water in the cleaning pool 31 after this cleaning. With the above arrangement, the cleanliness of the water in the cleaning pool 31 can be obtained in real time, and it can be judged whether the water in the cleaning pool 31 can continue to be used, so that the cleaning water can be used to the maximum extent.

[0047] In the control method of this embodiment, the method of drying the filter 10 includes: drying the filter 10 for a preset time; detecting the quality of the filter 10, and when the difference between the quality of the filter 10 and the quality of the filter 10 itself is less than a preset quality value, the drying is completed.

[0048] It should be noted that the quality of the filter 10 itself in this embodiment can be considered as the quality of a new filter 10 when it leaves the factory, or it can be considered as the quality of the filter when it is not wet.

[0049] Specifically, when the heater in the heating section is working, it will transfer heat to the surroundings. Since the heating section is a closed space, the heat will circulate in the section. When the filter arrives, it can be dried using the heat at this time. There will also be a waste heat recovery device nearby to collect excess heat from the heating section, exhaust section, surface cooling section, evaporation section and other functional sections. When the heating section is not working and the filter arrives, the heat in it is automatically released to dry it.

[0050] Embodiment 1:

[0051] This embodiment mainly includes the following six processes, which form a complete cycle process. After the sixth process is completed, the first process can be continued.

[0052] 1. Monitor the filter in real time to see if it is clogged.

[0053] 2. When the current filter is detected to be clogged, replace the current filter with a spare filter.

[0054] 3. Transfer the disassembled filter to the cleaning device for cleaning.

[0055] 4. Transfer the cleaned filter to the drying device for drying.

[0056] 5. Place the dried filter in the spare filter storage area for storage and transfer to the UV sterilizer for sterilization.

[0057] 6. Place the sterilized filter in the spare filter storage area for future use.

[0058] Embodiment 2:

[0059] The filtering system of this embodiment includes the following modules:

[0060] Monitoring module 1. This module is in the first process mentioned above. By real-time monitoring of the pressure difference between the inside and outside of the air inlet of the air conditioner unit, it can be determined whether the current filter 10 is blocked. High-definition three-dimensional cameras are installed before and after the filter 10. A preset three-dimensional image of the filter 10 when it is cleaned is displayed. When the difference between the three-dimensional image of the filter 10 and the preset image reaches a preset value, the system determines that the filter 10 is blocked at this time. If blockage is found, the second process mentioned above is activated.

[0061] Replacement module. This module is in the second process described above, by installing the stored spare filter 10 at the air inlet, and then removing the blocked filter 10. And perform the third, fourth, fifth, and sixth processes described above.

[0062] Cleaning module 3. This module is in the third process mentioned above, and the module mainly includes a cleaning pool 31, a water inlet, and a drain. Among them, the cleaning pool 31 is mainly a place to collect the condensed water generated by the unit itself and clean the filter 10. A water level sensor 32 needs to be installed here to monitor whether the clean water is sufficient to clean the filter 10; the water inlet is for replenishing clean water when the condensed water is not enough to clean the filter 10; the drain discharges the sewage after cleaning. When the cleaning module 3 receives the filter 10, it first checks the water level of the current stored condensed water. If the cleaning conditions are not met, clean water is replenished through the water inlet. After reaching the specified water level, the filter 10 is cleaned; the system presets the water cleanliness. After the cleaning is completed, the system monitors whether the water cleanliness in the current cleaning module 3 has exceeded the preset value. If it exceeds, the sewage is released through the drain and the fourth process mentioned above is executed. If it has not been reached, the water is kept for next use.

[0063] Drying module 4. This module is in the fourth process mentioned above. The module mainly includes monitoring and timing functions. The module is installed near the electric heating section of the unit, and the filter 10 is dried using the heat energy generated when the unit is working. After the drying module 4 receives the filter 10, it is first hung in the drying module 4 and dried for at least 3 minutes and at most 10 minutes. After the mass of the suspended filter 10 is monitored to be within the preset error (net weight of the filter 10), the drying process is considered to be completed, and the process is terminated immediately, and the fifth process mentioned above is executed. The filter 10 is sent to the ultraviolet sterilization module.

[0064] Ultraviolet sterilization module. This module is installed near the ultraviolet sterilization section and is used to sterilize the filter 10. The system monitors whether the bacterial value on the filter 10 is less than the preset bacterial value. If it is less, it is directly transferred to the filter storage. If it is greater than the preset bacterial value, the sterilization process begins until the sterilization ends when the bacterial value is less than the preset value, and the filter 10 is moved to the filter storage.
