Table 1: sensor temperature state, veneer state of temperature and report message tabulation
Figure G2009100826985D00101
Be illustrated in figure 2 as state of temperature according to an embodiment of the invention and shift schematic representation.As shown in Figure 2; Roll-off characteristic according to temperature; State of temperature only can change to adjacent state of temperature; But extreme case, state of temperature can be transferred to distance state far away fast at a temperature sampling in the cycle, but alarm information is removed the relation that message must embody a plurality of adjacent states conversions with alarm.If temperature acute variation; For example state directly is changed to normal state from upper limit high severity alarm; Do not sample upper limit minor alarm state; At this moment the report message transmitting module is through successively send " upper limit high severity alarm releasing " and " releasing of upper limit minor alarm " message continuously, and the bonding board status normally changes.
The system temperature state determination module of SHMC can be set up the state of temperature of each gusset plate according to the change of state report information that reports of each gusset plate, and SHMC is this state of uniform maintenance, and sets up the bulk temperature state of ATCA machine frame, i.e. system temperature state.The bulk temperature state of ATCA machine frame by gusset plate states all in the machine frame with " or " mode produce, promptly in the state of all gusset plates, the state that the temperature rank is the highest promptly is the bulk temperature state of ATCA machine frame.For example; 14 gusset plates are arranged in the ATCA machine frame, and wherein 11 deblocking temperature states are " normal state ", and 2 is " upper limit minor alarm state "; 1 is " upper limit high severity alarm state ", and the bulk temperature state of so whole ATCA machine frame is exactly " upper limit high severity alarm state ".
To the adjustment control of fan, also identical with the temperature sensor sampling cycle, simultaneously temperature is analyzed behind the temperature sampling, form the Current Temperatures state of gusset plate, form ATCA machine frame system temperature state then.When ATCA machine frame state of temperature changed, the corresponding control fan of rotation speed of fan control module was adjusted wind speed up or down.As one embodiment of the present of invention, the conversion relation of state of temperature as shown in Figure 2, wherein normal state is the comfortable operating temperature of veneer, the fan heat radiation is all right need not adjusted, and keeps present fan speed.When system is in " upper limit minor alarm state ", slowly increase fan speed, if when temperature reaches " upper limit high severity alarm ", need increase rotation speed of the fan rapidly, so that temperature is dropped to zone of reasonableness rapidly.When system reached " upper limit critical alarm state ", fan speed unconditionally was raised to 100%.When system was in " lower limit minor alarm state " and " lower limit high severity alarm state ", the fan wind speed slowly reduced.In case all veneer state of temperatures all are under " lower limit critical alarm state ", the unconditional stall of fan.
As one embodiment of the present of invention; When the system temperature state is " upper limit critical alarm state " and " lower limit critical alarm state "; Explain that promptly the ATCA system is in dangerous situation,, also need outwards to produce high severity alarm so that the notice manual intervention except blower fan is carried out the corresponding control.
As one embodiment of the present of invention, the rotating speed of blower fan is controlled general mode through direct control blower fan control signal and is realized, for example dutycycle and level etc.
As one embodiment of the present of invention; SHMC also comprises the control voltage regulator module; It is according to the may command degree of ATCA machine frame rotation speed of fan, and the control needs of machine frame heat radiation, and the mode of rotation speed of fan being pressed the dutycycle (PWM) of control voltage is divided into 16 grades of basic rotating speed control hierarchies.Certainly, for the blower fan of other types, also can adopt voltage to control.Each rank interval delta PWM=7%, from 0 grade of rotating speed to 15 grade rotating speed, corresponding respectively rotating speed is 0%, 7% ..., 42% ..., 91%, 98%, 100% totally 16 grades.0 grade is stall, and 15 grades is maximum (top) speed 100%.The numerical value of dutycycle is big more, and the rotating speed numbering is just big more, and the rotating speed of blower fan is fast more.The rotating speed basic controlling rank of blower fan is concrete to be defined as follows:
0 grade of rotating speed, rotating speed are 0, i.e. stall;
1 grade of rotating speed, corresponding hardware controls voltage duty cycle 7%;
2 grades of rotating speeds, corresponding hardware controls voltage duty cycle 14%;
6 grades of rotating speeds, corresponding hardware controls voltage duty cycle 42%;
7 grades of rotating speeds, corresponding hardware controls voltage duty cycle 49%;
13 grades of rotating speeds: corresponding hardware controls voltage duty cycle 91%;
14 grades of rotating speeds, corresponding hardware controls voltage duty cycle 98%;
15 grades of rotating speeds, corresponding hardware controls voltage duty cycle 100% is promptly changeed maximum (top) speed at full speed.
N PWMLevel rotation speed of fan rank, corresponding hardware controls voltage duty cycle PWM=(N PWM* 7) %, the rest may be inferred according to the order of sequence.As stated, controllable other maximum magnitude of rotation speed of fan level is between the 0-15 level, and the rotation speed of fan minimal level is 0 grade, and the class value of blower fan maximum (top) speed is 15 grades (100%).
Below illustrate the Policy description of the extent of actual control of concrete rotation speed of the fan, it can be configurable adjustment.
As one embodiment of the present of invention, blower fan adjusts upward rotating speed, and following three kinds of situation are arranged from low to high:
Adjust upward Δ N PWM_ Adj granularity adjustment rank;
Adjust upward Δ N PWMThe adjustment rank of _ Up granularity;
Directly adjust to maximum 100% situation.
Δ N wherein PWM_ Up＞Δ N PWM_ Adj.Δ N PWM_ Up is the adjustment step value of rotation speed of the fan rapidly, Δ N PWM_ Adj slowly increases the rotation speed of the fan step value.
For example, when ATCA machine frame system temperature state was in " upper limit critical alarm state ", fan speed was adjusted to full speed running, and in embodiment of the present invention, the control fan operation is at 15 grades of rotating speeds, i.e. maximum (top) speeds; When ATCA machine frame system temperature state was " upper limit high severity alarm state ", fan increased Δ N on existing rotating speed basis PWM_ Up increases substantially rotation speed of the fan, when for example existing rotating speed is 5 grades, if Δ N PWM_ Up=3, adjustment back wind speed is 8 grades (5 grades+Δ NPWM_Up) so; When ATCA machine frame system temperature state was " upper limit minor alarm state ", fan increased Δ N on existing rotating speed basis PWM_ Adj improves rotation speed of the fan by a small margin, when for example existing rotating speed is 5 grades, if Δ N PWM_ Adj=1, adjustment back wind speed is 6 grades of (5 grades+Δ N so PWM_ Adj).
As one embodiment of the present of invention, blower fan is adjusted rotating speed downwards and is comprised two kinds of situation:
Adjust Δ N downwards PWM_ Adj granularity adjustment rank;
Directly control the situation that fan is shut down.
As one embodiment of the present of invention, Δ N wherein PWM_ Adj and blower fan make progress the step value of rotating speed adjustment can be identical.
For example, when ATCA machine frame system temperature state was in " lower limit minor alarm state " and " lower limit high severity alarm state ", the fan wind speed slowly reduced, when for example existing rotating speed is 5 grades, if Δ N PWM_ Adj=1, adjustment back wind speed is 4 grades of (5 grades-Δ N so PWM_ Adj).Adjustment downwards can be adjusted to 1 grade, does not allow to adjust to 0 grade, when the stall of calm fan only appears at " lower limit critical alarm " state.
As one embodiment of the present of invention, during the blower fan steady state, if promptly be in " normal state " for the system temperature state of temperature sampling, blower fan will not need adjustment.
As one embodiment of the present of invention; SHMC also comprises the protection module that powers on; When the ATCA system just powers on,, therefore can't adjust fan according to the described controlling method of the foregoing description fully this moment because the IPMC of each gusset plate and SHMC also do not establish a communications link fully.Will design a guard time this moment, and this section period will be ignored the temperature information of all collections, and the protection module that powers on directly is set at 100% heat radiation, i.e. 15 grades of rotating speeds at full speed with rotation speed of the fan.This guard time is Tp, and the value of Tp was confirmed according to the time that the IPMC and the SHMC of gusset plate establishes a communications link, and is for example, proper at 3～5 minutes according to practice.
As one embodiment of the present of invention, SHMC also comprises initialization module, finishes in the guard time Tp time, before the adjustment rotation speed of the fan, needs to confirm each gusset plate state of temperature in the machine frame, and calculates the state of temperature of whole ATCA machine frame.SHMC can suppose that the temperature of each veneer is " normal state "; Each gusset plate IPMC collects before the temperature simultaneously; The temperature transducer acquiescence initial value of also supposing each gusset plate also is " normal state " temperature; Temperature inquiry like this, for the first time can obtain the temperature warning information of corresponding each gusset plate accurately.
Blower fan IPMC controls the blower fan that it connected according to the control of SHMC.Each blower fan IPMC can connect one or more blower fans, and wherein at least one blower fan IPMC connects two or more blower fans.As one embodiment of the present of invention, as shown in Figure 1, each blower fan IPMC connects 3 blower fans.
In the above embodiments, whole blower fans that SHMC controls in the whole machine frame adopt the same rotational speed operation, guarantee the radiating airflow uniformity in the ATCA machine frame.But; This only is an example of the present invention, in the practical implementation process, and can be according to the specific requirement of each gusset plate; Blower fan group to corresponding to each gusset plate is independently controlled; Like this, will make that the possibility rotating speed is different between the blower fan group, to reach accuracy control over temperature to each gusset plate.
Be illustrated in figure 3 as an embodiment's the flow chart of controlling method of the radiation fan of the ATCA system that the present invention proposes.As shown in Figure 3, this method may further comprise the steps:
S301: the temperature value of its region of temperature sensor measurement, and send this temperature value to gusset plate IPMC.
S302: gusset plate IPMC confirms the temperature transducer state of temperature transducer according to the temperature threshold of the temperature value of the temperature transducer on the gusset plate at its place and preset temperature transducer, and wherein the said temperature threshold of each temperature transducer comprises at least two temperature thresholds.
The temperature threshold of each temperature transducer can be set to identical, also can be provided with respectively according to the heat-resisting degree of the device of the requirement of veneer or temperature transducer region.
As one embodiment of the present of invention, the temperature threshold of each temperature transducer comprises 6 temperature thresholds, comprising 3 upper limit thresholds, and 3 lower thresholds, arrange from high to low according to temperature and to be respectively:
Upper limit critical alarm threshold value;
Upper limit high severity alarm threshold value;
Upper limit minor alarm threshold value;
Lower limit minor alarm threshold value;
Lower limit high severity alarm threshold value;
Lower limit critical alarm threshold value.
As one embodiment of the present of invention, based on the embodiment of above-mentioned 6 temperature thresholds, each temperature transducer state of temperature is 7 state of temperatures.For example, 7 state of temperatures and 6 kinds of temperature threshold relations can for:
The threshold temperature of upper limit critical alarm state＞=upper limit critical alarm＞
The threshold temperature of upper limit high severity alarm state＞=upper limit high severity alarm＞
The threshold temperature of upper limit minor alarm state＞=upper limit minor alarm＞
The threshold temperature of normal state＞=lower limit minor alarm＞
The threshold temperature of lower limit minor alarm state＞=lower limit high severity alarm＞
The threshold temperature of lower limit high severity alarm state＞=lower limit critical alarm＞
Lower limit critical alarm state.
Based on this embodiment, the veneer state of temperature of the gusset plate of below mentioning and the system temperature state of ATCA machine frame also comprise above 7 kinds of state of temperatures.
S303: gusset plate IPMC confirms the veneer state of temperature of this gusset plate according to the temperature transducer state on the gusset plate.
As one embodiment of the present of invention, consider the too high emergency treatment that more needs of temperature, therefore can be with the temperature rank is the highest in a plurality of temperature transducer states sensor states as the veneer state of temperature.
S304: gusset plate IPMC sends the change of state report message according to the variation of veneer state of temperature to Shelf Management Controller SHMC.
As one embodiment of the present of invention, corresponding to above-mentioned 6 kinds of temperature thresholds and 7 state of temperatures, gusset plate IPMC can 6 kinds of temperature warning message of corresponding generation remove message with 6 kinds of corresponding alarms.As one embodiment of the present of invention; It is not identical temperature value that the threshold temperature of alarm releasing incident produces threshold temperature with alarm; Differ a temperature value Δ T of design in advance between them; To avoid when the alarm threshold line changes up and down, producing too much incident report, certain damping function is arranged when temperature.
For example; When the sensor temperature value is higher than " upper limit threshold of high severity alarm " temperature arbitrarily on the gusset plate; Gusset plate IPMC module can detect this temperature and send " upper limit high severity alarm message " to SHMC; In the time of under this TEMP actuator temperature drops to " upper limit threshold of high severity alarm " temperature, gusset plate IPMC can send " message is removed in upper limit high severity alarm " to SHMC.
As one embodiment of the present of invention; Roll-off characteristic according to temperature; State of temperature only can change to adjacent state of temperature; But extreme case, state of temperature can be transferred to distance state far away fast at a temperature sampling in the cycle, but alarm information is removed the relation that message must embody a plurality of adjacent states conversions with alarm.If temperature acute variation; For example state directly is changed to normal state from upper limit high severity alarm; Do not sample upper limit minor alarm state; At this moment gusset plate IPMC is through successively send " lower limit high severity alarm releasing " and " general upper limit alarm is removed " message continuously, and the bonding board status normally changes.
The change of state report message that S305:SHMC sends according to each gusset plate IPMC is controlled the rotation speed of fan of radiation fan.
SHMC can set up the state of temperature of each gusset plate according to the change of state report information that reports of each gusset plate, and SHMC is this state of uniform maintenance, and sets up the bulk temperature state of ATCA machine frame, i.e. system temperature state.The bulk temperature state of ATCA machine frame by gusset plate states all in the machine frame with " or " mode produce, promptly in the state of all gusset plates, the veneer state of temperature that the temperature rank is the highest promptly is the bulk temperature state of ATCA machine frame.For example; 14 gusset plates are arranged in the ATCA machine frame, and wherein 11 deblocking temperature states are " normal state ", and 2 is " upper limit minor alarm state "; 1 is " upper limit high severity alarm state ", and the bulk temperature state of so whole ATCA machine frame is exactly " upper limit high severity alarm state ".
When ATCA machine frame state of temperature changed, the corresponding control fan of SHMC was adjusted wind speed up or down.As one embodiment of the present of invention, normal state is the comfortable operating temperature of veneer, and the fan heat radiation is all right need not adjusted, and keeps present fan speed.When system is in " upper limit minor alarm state ", slowly increase fan speed, if when temperature reaches " upper limit high severity alarm ", need increase rotation speed of the fan rapidly, so that temperature is dropped to zone of reasonableness rapidly.When system reached " upper limit critical alarm state ", fan speed unconditionally was raised to 100%.When system was in " lower limit minor alarm state " and " lower limit high severity alarm state ", the fan wind speed slowly reduced.In case all veneer state of temperatures all are under " lower limit critical alarm state ", the unconditional stall of fan.
As one embodiment of the present of invention; When the system temperature state is " upper limit critical alarm state " and " lower limit critical alarm state "; Explain that promptly the ATCA system is in dangerous situation,, also need outwards to produce high severity alarm so that the notice manual intervention except blower fan is carried out the corresponding control.
As one embodiment of the present of invention, the rotating speed of blower fan is controlled general mode through direct control blower fan control signal and is realized, for example dutycycle and level etc.
As one embodiment of the present of invention, according to the may command degree of ATCA machine frame rotation speed of fan, and the control needs of machine frame heat radiation, the mode of rotation speed of fan being pressed the dutycycle (PWM) of control voltage is divided into 16 grades of basic rotating speed control hierarchies.Certainly, for the blower fan of other types, also can adopt voltage to control.Each rank interval delta PWM=7%, from 0 grade of rotating speed to 15 grade rotating speed, corresponding respectively rotating speed is 0%, 7% ..., 42% ..., 91%, 98%, 100% totally 16 grades.0 grade is stall, and 15 grades is maximum (top) speed 100%.The numerical value of dutycycle is big more, and the rotating speed numbering is just big more, and the rotating speed of blower fan is fast more.The rotating speed basic controlling rank of blower fan is concrete to be defined as follows:
0 grade of rotating speed, rotating speed are 0, i.e. stall;
1 grade of rotating speed, corresponding hardware controls voltage duty cycle 7%;
2 grades of rotating speeds, corresponding hardware controls voltage duty cycle 14%;
6 grades of rotating speeds, corresponding hardware controls voltage duty cycle 42%;
7 grades of rotating speeds, corresponding hardware controls voltage duty cycle 49%;
13 grades of rotating speeds: corresponding hardware controls voltage duty cycle 91%;
14 grades of rotating speeds, corresponding hardware controls voltage duty cycle 98%;
15 grades of rotating speeds, corresponding hardware controls voltage duty cycle 100% is promptly changeed maximum (top) speed at full speed.
N PWMLevel rotation speed of fan rank, corresponding hardware controls voltage duty cycle PWM=(N PWM* 7) %, the rest may be inferred according to the order of sequence.As stated, controllable other maximum magnitude of rotation speed of fan level is between the 0-15 level, and the rotation speed of fan minimal level is 0 grade, and the class value of blower fan maximum (top) speed is 15 grades (100%).
