[0002] With the rapid development of modern communication industry, the number of communication base stations has increased sharply. The communication base station machine room is generally designed to be fully enclosed. The power equipment, transmission equipment, etc. in the base station work continuously and generate a large amount of heat. The base station equipment has relatively high requirements for the environmental temperature and requires long-term operation of temperature control equipment. The fresh air system of the base station is an efficient and energy-saving way to cool the base station, which uses the temperature difference between indoor and outdoor and forced ventilation for convective heat dissipation; makes full use of natural resources to adjust the indoor temperature to achieve the purpose of power saving and energy conservation. However, after long-term use, a lot of dust and sundries will accumulate on the filter screen, and it needs to be disassembled, installed and cleaned manually. Since the communication base station generally operates automatically and has no one on duty, the frequent manual disassembly, installation and cleaning of the air inlet filter screen bring a lot of inconvenience to the actual work. At the same time, if the filter screen is not replaced and cleaned in time, the temperature of the machine room will rise, causing equipment overheating and damage.
