Abstract
The invention provides a method for improving the temperature detection precision of an air inlet, which comprises the following steps: optimizing the air inlet position of the air inlet of the system by using the paster; and (4) calculating the temperature of the air inlet through internal Sensor data by utilizing a large amount of data simulation. By optimizing the system air channel, the temperature collected by the internal temperature collection point is not influenced by the rotating speed of a CPU, a hard disk and a fan in the system, and the ambient temperature of the air inlet is reduced as truly as possible.
Description
Technical field
The present invention relates to computer server unit test field, particularly relate to a kind of method improving air intake vent temperature detecting precision.
Background technology
In the machine room of southern Ali client, due to computer room construction, machine room O&M can not Remote Acquisitioning to the temperature of machine room internal environment.Therefore each server in machine room is needed to provide air intake vent temperature detecting function to detect the environment temperature of variant position in machine room.
Certain machine of the current supply of material, do not have to consider to detect the environment temperature of air intake vent in development and Design, all temperature monitoring points are all placed on machine intimate.Therefore need in the existing design of this machine, by optimizing system air channel, the temperature that internal temperature collection point is collected does not affect by CPU, hard disk, rotation speed of the fan in system, as far as possible truly reduces the environment temperature of air intake vent.
Summary of the invention
Technical assignment of the present invention is for the deficiencies in the prior art, provides a kind of method improving air intake vent temperature detecting precision.By being optimized 2U server system air intake vent, the distinguished and admirable flow direction according to one of internal system being carried out, guarantees that the Sensor control point temperature-difference at air intake vent temperature and rear portion, air channel changes less.
The technical solution adopted for the present invention to solve the technical problems is:
Improve a method for air intake vent temperature detecting precision, comprising: utilize paster, the inlet air position of optimization system air intake vent; Utilize mass data to simulate, calculate air intake vent temperature by inner Sensor data.
The inlet air position of optimization system air intake vent, changes internal system air channel trend, ensures the difference stability of internal system temperature Sensor collection point and external environment condition.
By the secondary development to product, introduce transparent paster at production link and carry out system air intake vent transformation of air duct, utilize formulae discovery, guarantee that internal system temperature acquisition Sensor shows air intake vent environment temperature accurately, reach the actual demand of Ali client's machine room.
A kind of method improving air intake vent temperature detecting precision of the present invention compared with prior art, the beneficial effect produced is, by optimizing system air channel, the temperature that internal temperature collection point is collected does not affect by CPU, hard disk, rotation speed of the fan in system, the true as far as possible environment temperature must reducing air intake vent.
Embodiment
Below in conjunction with embodiment 1, a kind of method improving air intake vent temperature detecting precision of the present invention is described in detail below.
Embodiment 1:
Improve a method for air intake vent temperature detecting precision, comprising: utilize paster, the inlet air position of optimization system air intake vent; Utilize mass data to simulate, calculate air intake vent temperature by inner Sensor data.
First the air channel in present system is analyzed, and by amendment air inlet, change internal system air channel trend, ensure the difference stability of internal system temperature Sensor collection point and external environment condition.Owing to not doing temperature acquisition function in the front window, handle design of whole cabinet, therefore in order to realize the function of this system display air intake vent environment temperature, can only look for from machine intimate mainboard and getting the point nearest from air intake vent position-" Q28 position " as air intake vent temperature monitoring point.
Whole cabinet has anterior three the main air inlets of cabinet both sides sidewall, cabinet hard disk support bracket.The wind that fan extracts after work all enters from three air intake vents.
According to the configuration of mainboard and cabinet, extraneous air flows into from air intake vent in theory, and in system, each parts are to the Q28 position of mainboard, so Q28 position reading should time accurately indicate the initial temperature of extraneous air.
But find in reality test link:
The hard disk of cabinet front is in running order, can send certain heat.
Along with rotation speed of the fan is different, can change from the air quantity of side air intake vent, front air intake vent.
The change of divergence of the numerical value that reads out of two kinds of uncertain conditional decisions Q28 and outside atmosphere temperature is comparatively large above, and maximum measuring error has arrived 5 degree, exceed accuracy test standard.
According to the principle analysis to above-mentioned inlet air passage, offside air intake vent is closed, air intake vent position before only retaining, and object to ensure Hard disk heat radiation demand, there will not be again and changes amplitude problem greatly because enter air quantity from the different Q28 that cause of position.
By above-mentioned transformation of air duct, when only retaining front air intake vent, the temperature that Q28 station acquisition arrives changes in various external environment, hard disk pressure changes, diminish with the change of divergence of external air temperature, advantageously in calculating ambient temperature by formula.
The scheme of final confirmation is: utilize transparent paster to touch both sides air intake vent, adopts mainboard Q28 (PCHTEMP) image data and finally show that formula is as follows: Y(air intake vent temperature)=1.17 × Q28-21.1
After process, calculating EAT and actual temperature deviation are between-3.3 ~ 5.3 DEG C, and the point of 320 data deviations more than 3 has 11, and deviation is 96.6% at the ratio data of ± 3 scopes, the requirement of satisfied temperature measuring accuracy.
By the secondary development to product, introduce transparent paster at production link and carry out system air intake vent transformation of air duct, utilize formulae discovery, guarantee that internal system temperature acquisition Sensor shows air intake vent environment temperature accurately, reach the actual demand of Ali client's machine room.
