Device and method for monitoring filter screen of outdoor equipment room fresh air ventilating system

Abstract

The invention discloses a device and method for monitoring a filter screen of an outdoor equipment room fresh air ventilating system. The device provided by the invention comprises a dust sensor, a pressure difference switch and a microcomputer control module, wherein pressure difference signals are transmitted to the microcomputer control module by the pressure difference switch; the dust sensoracquires dust concentration signals on the two sides of the filter screen respectively, and transmits the signals to the microcomputer control module; the microcomputer control module calculates the difference value of the actual dust concentration after receiving the dust concentration signals; when the difference value of the actual dust concentration is less than the preset limit difference value of the dust concentration, the microcomputer control module gives out an alarm; and at the same time, when receiving pressure difference alarm signals, the microcomputer control module gives out the alarm. Thus, personnel can be aware of the blockage of the filter screen through the pressure difference alarm signals sent out by the pressure difference switch, the condition of damage to the filter screen can also be known through calculating the dust concentration signals transmitted by the dust sensor by virtue of the microcomputer control module, thus the convenience is ensured.

Description

technical field [0001] The invention relates to a monitoring technology for a filter screen of a fresh air system in an outdoor computer room, and more specifically relates to a monitoring device and method for a filter screen of a fresh air system in an outdoor computer room. Background technique [0002] With the rapid development of the Internet and data services, the frequency of use of outdoor computer rooms is increasing. Compared with the indoor computer room, the environment of the outdoor computer room is relatively harsh, and it is easily affected by adverse factors such as temperature, humidity, and dust. Most of the outdoor computer rooms now use the fresh air system for energy-saving considerations. Since the outdoor air is in direct contact with the equipment in the computer room, in order to ensure the cleanliness of the computer room, a filter is installed at the air inlet of the fresh air system. However, during use, the filter screen is often blocked, whic...
