Description
Technical field
The present invention relates to the technical field of heat dissipation of electronic product, be specifically related to a kind of machine frame detecting clogging of dust screen and
Detection device.
Technical background
The heat radiation majority of electronic equipment is realized by wind-cooling heat dissipating at present, and the performance of wind-cooling heat dissipating system is to electronics
The stable operation of equipment is most important.In order to reduce dust to the impact of electronic equipment and corrosion, most wind-cooling heat dissipating systems are all
Air Filter, particularly exigent to system reliability communication equipment can be installed.The laying dust state of Air Filter can directly affect
The air-cooled performance of equipment, thus affect the safe and stable operation of electronic equipment.
Existing communication electronic equipment is required to regularly detect Air Filter and safeguard, it is ensured that equipment is normally transported
OK.This needs to put into bigger human cost, and due to the multiformity of equipment operating environment, the stopping state of Air Filter is the most not
Equally, periodic maintenance can not guarantee that Air Filter keeps normal condition constantly completely.It is thus desirable to provide a kind of Air Filter blocking
Detection method, in order to alert when Air Filter blocks.
In prior art, having two kinds of technology carrying out Air Filter chocking-up degree detection, one is laser measuring technology, another
Planting is rotation speed of the fan detection technique, following is a brief introduction of both technology.
One, laser transmission detection technique
This technology utilizes laser to run into barrier can change the principle of transmitted light intensity, and concrete grammar is: by laser instrument to Air Filter
Launching laser, laser can be decayed during transmission from Air Filter, and the attenuation degree of laser is thick by the dust on Air Filter
Degree impact, therefore by detection from the transmitted light intensity of the laser of Air Filter transmission, it may be determined that the blocked state of Air Filter.This skill
Art General Implementing difficulty is relatively big, relatively costly.Firstly the need of special generating laser and detector, and need to take necessarily
Space；Secondly laser instrument radiation pattern is based on point, is difficulty with the covering to whole Air Filter plane；Last laser class device
The life-span of part itself is relative the shortest, more difficult at the occasion working service that cannot be convenient for changing.
Two, fan wind speed detection technique
Directly affecting of causing after blocking due to Air Filter is that the wind speed in gas channel reduces, and therefore this technology is flowed by detection
Wind speed in Air Filter gas channel, and the wind speed detected is compared with wind speed during Air Filter cleaning, to determine
Air Filter chocking-up degree, wind speed reduces and shows that the most greatly Air Filter blocking is the most serious.
The realization of this technology, it is necessary first to select suitable position to place wind speed measurement unit in the lower air port of Air Filter,
If wind speed measurement unit is taken up space relatively big, then itself will keep out the wind, and then affects system radiating；If taken up space relatively
Little, then cannot intactly detect the integral status of Air Filter blocking.
Summary of the invention
Present invention aim at providing a kind of machine frame detecting clogging of dust screen, it is possible to detect quickly and easily and reflect
Go out the blockage of machine frame Air Filter.

(3), pre-setting temperature difference alarm threshold value, jam detection unit calculates T2Temperature and T1Difference DELTA T of temperature, and
By this Δ T compared with temperature difference alarm threshold value；If Δ T is without departing from alarm threshold value scope, judge that Air Filter blockage is good
Good；If Δ T exceeds alarm threshold value scope, judging that Air Filter blockage is unacceptable, now jam detection unit sends and reports to the police
Signal gives an Alarm Unit；
(4), after Alarm Unit receives alarm signal, the alarm response that people can be allowed to perceive is sent.
Preferably, in above-mentioned step (3), being previously provided with two-stage temperature difference alarm threshold value, the first order is slight announcement
Alert, the second alarm threshold value is high severity alarm.
Present invention also offers a kind of machine frame Air Filter blockage detector, including temperature detecting unit, jam detection list
Unit and Alarm Unit；Temperature detecting unit is made up of intake air temperature detection module and heater members temperature detecting module, stifled
Plug detector unit is made up of interconnective processing module and memorizer；Intake air temperature inspection included in temperature detecting unit
Survey module and heater members temperature detecting module is connected with the processing module included in jam detection unit respectively, blocking
Processing module included in detector unit is connected with Alarm Unit.
The method have technical effect that:
(1) cause ventilation not smooth during Air Filter blocking, have influence on the heat radiation of machine frame internal heat generation device, cause the temperature of heater members
Abnormal can rise, and the temperature of air inlet detection will not change, heater members temperature and intake air temperature with Air Filter blocking
Both differences, are affected by Air Filter chocking-up degree, therefore can be determined by the temperature difference of particular detection point in detection machine frame
The blocked state of Air Filter, and give a warning information according to the blockage of Air Filter, this machine frame Air Filter jam detection side
Method is the most effective.
(2) in machine frame Air Filter blockage detector provided by the present invention.Temperature detecting unit is arranged on inside machine frame,
The temperature of different parts in obtaining machine frame, and the temperature information got is sent to jam detection unit.Jam detection
The temperature information that temperature detecting unit is sent by unit collects, computing, and by operation result and the alarm of setting in system
Threshold values contrasts, to determine the chocking-up degree of Air Filter.If reaching alarming threshold, then start Alarm Unit.Alarm Unit
After receiving alarm command, send alarm, remind attendant to clear up Air Filter in time.
