Method for detecting dustproof filter screen by temperature difference and device utilizing method

Abstract

The invention relates to a method for detecting a dustproof filter screen by temperature difference and a device utilizing the method. The method is applicable to equipment heating internally and includes steps of 1) detecting external environment temperature and internal environment temperature of the equipment; 2) indexing according to current power and temperature difference and searching reference tables (power, temperature difference and wind force value) stored in the system by means of the temperature difference of the external environment temperature and the internal environment temperature, and acquiring wind force value which is called as effective wind force value; 3) reading a storage device on a fan controller to acquire the current actual wind force value; and 4) comparing the effective wind force value with the actual wind force value, then reporting alarm / accidents if the comparison value is smaller than a threshold range set by the system, and repeating the steps of 1), 2), 3) and 4). The method for detecting the dustproof filter screen has the advantages that a detecting mechanism can be quantized, maintenance efficiency is improved, maintenance cost is reduced, the equipment is stable in working, the service lives of the equipment and fans are prolonged and cost of the system is low.

Description

technical field [0001] The invention relates to the field of dustproofing of electronic equipment, more specifically, to a method and device for detecting dustproof filter nets by temperature difference. Background technique [0002] During the long-term operation of electronic equipment, if a large amount of dust accumulates, it will affect the heat dissipation effect of the electronic equipment and reduce the service life of the electronic equipment. Therefore, in equipment such as communication equipment and industrial computer, since the internal temperature of the equipment will be relatively high, fans will be introduced, and dust-proof filters will also be introduced. [0003] Now technology generally adopts two methods to dissipate heat. [0004] One method is to adopt the typical blowing mode: the wind is blowing towards the inside to achieve the effect of reducing the temperature; the other method is the suction mode: the wind is blowing towards the outside, so th...

AI Technical Summary

Problems solved by technology

[0008] 1. Engineers are required to regularly inspect on-site;

[0009] 2. There is a lack of scientific indicators to judge whether it should be cleaned or the dust-proof net, whether it is too dirty or relatively clean depends on human judgment;

[0010] 3. The dust-proof net cannot be removed in time. If the dust-proof net is too dirty, it means that the dust-proof net has not been replaced or cleaned in a timely and effective manner, which may cause the device to work in a high temperature state, affecting the stable operation of the device or the fan needs to increase the speed, affecting the fan. service life;

[0011] 4. If the dust-proof net is relatively clean, for example, it may only need to be cleaned after 6 months, but out of conservative considerations, it will be cleaned once every 3 months, and frequent manual inspections, the engineer is equivalent to doing some invalid work, especially some The distance between equipment and engineers is relatively far, and it is impossible to reduce maintenance labor costs
