Abstract
The invention discloses a test method for verifying PID fan regulation and control. The method comprises the steps that the system component temperature, the system fan rotation speed, the air inlet temperature, the CPU and the memory power consumption are captured in real time through system scripts; when a normal-temperature and high-temperature heat dissipation verifying test is carried out, if the system pressure changes suddenly, the corresponding relation of the system component temperature and the fan rotation speed can be recorded in real time, and whether the fan regulation and control strategy meets the system heat dissipation requirement or not is verified in real time. By the adoption of the test method, the corresponding relation of the system component temperature and the fan rotation speed can be monitored in real time, whether the fan regulation and control strategy is feasible or not is determined, the fan regulation and control strategy of a server is fully verified, and the system overheating or shutdown is prevented.

Method.
Background technology
Current closed-loop automatic control technology is all based on the concept fed back to reduce uncertainty.The key element of feedback theory
Including three parts:Measure, compare and perform.Measurement concerns the actual value of controlled variable, compared with expected value, uses this
Individual deviation carrys out the response of correcting system, performs and adjusts control.In engineering in practice, the actuator control law being most widely used
For ratio, integration, differential control, abbreviation PID control, also known as PID regulations.
PID controller (proportional-integral derivative controller) is a common feedback circuit portion in Industry Control Application
Part, is made up of proportional unit P, integral unit I and differentiation element D.
This it is theoretical and application it is crucial that making and correctly measure and compare after, how could preferably correcting system.
PID (ratio (proportion), integration (integration), differential (differentiation)) controller is made
Currently still it is most widely used industrial control unit (ICU) for the existing last 100 yearses history of controller practical earliest.PID controller
It is easily understood, the prerequisite such as accurate system model is not required in use, thus becomes the controller being most widely used.
Because the fan regulation and controlling strategy of server all has been introduced into PID calculus fan regulation and controlling methods, it is possible to achieve clothes
Business device stepless time adjustment, with the temperature change constantly regulate fan of monitoring part；Can be increased according to algorithm real-time monitoring fan simultaneously
Amount of increase degree, controls the temperature energy infinite approach specification temperature of server internal part, rather than as linear regulation mode is with temperature
Change is significantly increased rotating speed, and then entirety reduces system power dissipation.But calculus PID regulation and control need constantly to be captured by BMC chip
Temperature, and need just calculate rotation speed of the fan at this temperature through series of computation, if the BMC crawl temperature interval times
It is long, or setting program calculates problematic, when suddenly pressurization, BMC is calculated and is had certain hysteresis quality, causes system unit temperature
Degree has excess temperature phenomenon, and can delay machine phenomenon when serious.But this hysteresis are very of short duration, Jing often cannot have found, be badly in need of
Want a kind of means to verify, and be modified.
Existing technical scheme is to carry out room temperature and high temperature radiating test, the temperature of each part in an authentication server system
Whether meet temperature profile, but when cannot verify that pressure pressurizes suddenly rotation speed of the fan and system unit temperature fluctuation.

Fruit is when changing suddenly, can under real time record system unit temperature and rotation speed of the fan corresponding relation, real-time verification fan
Whether regulating strategy meets system radiating demand.
The system script directly read using system ipmi function depositor rotation speed of the fan and intake air temperature information,
Power consumption information etc., because the crawl information of depositor in system can be controlled within 1S.
IPMI (IPMI), is a kind of hardware management interface specification of open standard, is defined embedded
The ad hoc approach that management subsystem is communicated.IPMI information (is located at IPMI specifications by baseboard management controller (BMC)
Nextport hardware component NextPort on) exchanged.Operating system is not used to be managed using low-level hardware intelligent management, with two masters
Want advantage:First, this configuration allows to carry out with outer server admin;Secondly, operating system need not bearing transport system mode number
According to task.
Methods described is using the crawl in real time of intel ptumon softwares or reads the temperature information of depositor to obtain CPU's
Temperature and power consumption.The PTUmon softwares of intel read the information such as the cpu temperature in depositor, can be controlled within 0.5S,
So can be integral monitoring error control within 1S.
Methods described enters one according to PID designs, parameter Kp, Ki and Kd parameters of the output of real time record fan regulation and controlling
Whether the fan regulation and controlling strategy of step card output meets design.
Methods described operating process is as follows：
1）Server critical component bonding thermocouple wire；
2）Setting operating ambient temperature；
3）Initialization system pressurization software；
4）The applied voltage test checking under the operating ambient temperature of setting, using system script real-time monitoring system part temperatures and wind
Fan rotating speed is confirmed whether there is fluctuation；
5）PID fan regulation and controlling schemes are confirmed according to test result；
6）If regulation and control scheme meets, scheme determines；
7）If regulation and control scheme does not meet, return to step 4）.
Beneficial effects of the present invention are：
The present invention can confirm that fan regulation and controlling strategy whether may be used with real-time monitoring system part temperatures and the corresponding relation of rotation speed of the fan
OK, the fan regulation and controlling strategy of abundant authentication server, anti-locking system excess temperature or machine of delaying.
