It should be noted that method described in following embodiments can be shown according to the structure of each module of unit shown in FIG. 1
It is intended to execute.
In order to solve the problem of frequently to trigger error protection, the embodiment of the present invention under certain conditions in the prior art
A kind of method for adjusting unit operating parameter is provided, as shown in Fig. 2, this method includes：
Step S201, judge whether the current operating conditions of unit reach preset state.
Wherein, preset state is to trigger the state of fault protection scheme；
Step S202, when operating status reaches preset state, the operating parameter of unit is adjusted.
Thus, it is possible to be joined when unit reaches the state of triggering fault protection scheme by the operation of adjust automatically unit
Number, avoid unit afterwards in use, under environment complicated and changeable outside factory, continually trigger fault protection scheme.To mention
The usage experience for rising user, reduces the complaint of user.
Wherein, before step S201, this method can also include：Unit is powered operation, and air-conditioner control system is from storage
Equipment obtains the solidification operating parameter (for example, running frequency of compressor) when unit factory, and according to solidification operating parameter control
The operation of unit processed.And in the operational process of unit, sensor real-time monitoring or every preset duration detection system pressure, pressure
The running parameters such as contracting machine delivery temperature, if it is when being not up to preset state, to continue according to current solidification that parameter is without exception
Operating parameter operation.
In one possible implementation, step S201, judge whether the current operating conditions of unit reach default shape
State may include：Monitor the current running parameter of unit；Judge whether running parameter meets preset condition；Wherein, preset condition
It is that running parameter and the difference of preset failure value are in preset range；If it is, determining that unit reaches preset state.Wherein,
Running parameter includes at least following one：The system pressure of unit, the compressor exhaust temperature of unit and intelligent power module
IPM temperature.
In one possible implementation, step S201, judge whether the current operating conditions of unit reach default shape
State can also include：Determine the present mode of operation of unit；Judge whether present mode of operation is in fault protection scheme；Such as
Fruit is, it is determined that unit reaches preset state.Wherein, present mode of operation is fan trouble protected mode or communication response rate event
Hinder protected mode.
It is understood that judging whether the current operating conditions of unit reach the method for preset state for unit
When different loads, it is different.For example, can directly pass through pressure when running parameter is system pressure, compressor exhaust temperature etc.
Force snesor or temperature sensor detect current system pressure and current delivery temperature.Then when running parameter and preset failure
When the difference of value is in preset range, illustrate that running parameter is just gradually leveling off to preset failure value (running parameter and preset failure
The size relation of value is simultaneously not fixed).At this point, the operating parameter of unit is adjusted before running parameter is not up to preset failure value,
So that the velocity of approach of the running parameter of unit and preset failure value is slack-off or gradually decreases, that is, it can avoid triggering error protection mould
Formula.
But certain loads for unit, such as blower, then can not directly detection blower fan revolving speed, different from above-mentioned root
Determine whether to trigger fault protection scheme according to the relationship of running parameter and preset failure value, but triggered for the first time when blower therefore
When hindering protected mode, the just signal as the adjustment operating parameter for feeding back to unit.Then failure can be triggered for the first time in blower to protect
When shield mode, operating parameter is adjusted, to avoid afterwards in use, blower frequently triggers fault protection scheme.Wherein,
Blower can be DC fan.And it should be noted that it is an object of the invention to avoid unit from frequently triggering error protection
Mode, rather than unit is utterly avoided to trigger fault protection scheme.And in above-mentioned running parameter and present mode of operation
When any one reaches the state of triggering fault protection scheme, it can trigger the Regulation mechanism of unit, operating parameter adjusted
It is whole.
Above-mentioned two possible implementation is illustrated separately below.It is system pressure or compression in running parameter
When machine delivery temperature, the operating parameter of unit is adjusted, including：The running frequency of compressor is lowered into F；After being spaced preset time,
If system pressure is still>The-the first preset difference value of system pressure preset failure value or compressor exhaust temperature>Delivery temperature
The-the second preset difference value of preset failure value will then regulate the speed and accelerate Δ v, and adjustment amplitude increases Δ F；When adjustment number is n times
When, it regulates the speed as V+ (N-1) Δ v, adjustment amplitude is F+ (N-1) Δ F, until unit is in stable state；Wherein, V is first
Beginning regulates the speed, and F is initial adjustment amplitude, and Δ v is the variable quantity regulated the speed each time, and Δ F is to adjust amplitude each time
Variable quantity.When running parameter is IPM temperature, the operating parameter of unit is adjusted, including：Compressor operating frequency is lowered into F；Between
After preset time, if IPM temperature is still>Compressor is then run frequency by IPM temperature preset failure value-third preset difference value
Δ v is accelerated in regulating the speed for rate, and adjustment amplitude increases Δ F；Rotation speed of fan is promoted into Δ R；When adjusting number is n times, adjustment
Speed is V+ (N-1) Δ v, and adjustment amplitude is F+ (N-1) Δ F；Rotation speed of fan is R+ (N-1) Δ R, until unit, which is in, stablizes shape
State；Wherein, V is initially to regulate the speed, and F is initial adjustment amplitude, and Δ v is the variable quantity regulated the speed each time, and Δ F is each
The variable quantity of secondary adjustment amplitude, R are initial rotation speed of fan, and Δ R is the variable quantity for adjusting revolving speed each time.
Wherein, if a sensor senses that the parameters such as system pressure, compressor exhaust temperature, IPM temperature occur it is abnormal,
When meeting preset condition, then it can adjust the operating parameter of unit.For example, when system pressure is apparently higher than or is surveyed lower than in factory
The delivery temperature rising of the system pressure value (system pressure preset failure value) or compressor of examination is higher, with preset failure value
Difference comparsion is close, and when being in the second preset difference value, then unit actively enters self-control mode, reduces the fortune of compressor
Line frequency improves rotation speed of fan, and after adjusting each time, again monitoring parameter, if running parameter still accords with
Preset condition is closed, then increases adjustment dynamics according to above formula, for example, increasing the amplitude of compressor frequency decline, accelerates compression
The speed of unit frequency decline, improves the revolving speed etc. of blower.After adjustment, monitoring parameter again, until running parameter no longer accords with
Preset condition (state for no longer reaching triggering fault protection scheme) is closed, unit tends towards stability after operation.Stop adjustment.
It increases it should be noted that above-mentioned possible implementation describes running parameter and approaches preset failure value
Situation.In real life, running parameter may also reduce and level off to the lowest critical value of preset failure value.For example, system
Pressure may the raising when the installation site of outdoor unit causes to divulge information unsmooth, it is also possible to the reduction when system lacks fluorine.It is understood that
, when system pressure or the reduction of remaining running parameter, adjust the process and above system pressure or remaining work of operating parameter
The adjustment process made when parameter raising is opposite.
When present mode of operation is fan trouble protected mode, the operating parameter for adjusting unit includes：By rotation speed of fan
Δ R is lowered, when adjusting number is n times, rotation speed of fan is R+ (N-1) Δ R, until blower is in stable state.It is transported currently
When row mode is communication response rate fault protection scheme, the operating parameter for adjusting unit includes：When unit communication response rate is lower than
When default communication response rate, communication baud rate, and the situation of change of real-time monitoring communication response rate are adjusted；If communicating response rate
It reduces, then opposite direction adjusts communication baud rate, until communication response rate is greater than or equal to default communication response rate.
Wherein, the factors such as temperature will cause the deviation of communication baud rate and communication response rate caused to change, to lead
Cause system receives abnormal.As a result, can be when monitoring unit communication response rate lower than default communication response rate, adjustment communication baud
Rate, and the situation of change of real-time monitoring communication response rate.Response rate fault protection scheme is communicated to avoid frequently entering.
Inventor has found that being not limited to system pressure, compressor air-discharging for the detection of operating states of the units
Temperature etc., can also comprising monitoring to parameters such as air quality, running current, working voltage, each device temperatures, can be related to be
In terms of system or controller.Correspondingly, system high pressure is not limited to the adjustment of operating parameter when triggering fault protection scheme
Adjustment to parameter when protection, delivery temperature protection, drive module protection, blower protection, communication failure protection can also include
Correspondence regulating measures when remaining fault protection scheme can carry out unit comprehensive monitoring as a result, further avoid unit
Frequently triggering fault protection scheme.
It should be noted that step S202, adjust unit operating parameter after, method further includes：When the fortune of unit
When row parameter reaches critical value, stop adjustment；Wherein, operating parameter includes at least following one：Compressor operating frequency, blower
Revolving speed, communication baud rate.
It is understood that being further continued for being adjusted, will affect system when the operating parameter of unit reaches critical value
Operation or load performance.Wherein, critical value can be set by producer according to air-conditioner set and the performance of load.By
This, can avoid during the adjustment, damaging unit.
In one possible implementation, as shown in figure 3, step S202, adjust unit operating parameter after, this
Inventive embodiments also provide a kind of method for adjusting unit operating parameter, and this method includes：
If step S203, unit is in being run multiple times before not powering off, it is in stable state；Then store operation adjusted
Parameter, so that unit can start after power-off restarting according to operating parameter adjusted.
Wherein, being run multiple times before unit does not power off can be unit and repeatedly shut down being run multiple times after restarting, that is, locate
In standby mode.And when storing operating parameter adjusted, the process that can also store adjustment operating parameter namely adjusts mould
Formula.Thus, it is possible to unit is started after power-off restarting according to the operating parameter for being not easy to trigger fault protection scheme after adjustment,
Rather than start according still further to cure parameter, it can further avoid continually triggering fault protection scheme.
In one possible implementation, as shown in figure 3, step S202, adjustment unit operating parameter after,
Method further includes：
If step S204, unit still in preset state, then prompts user to tie up in being run multiple times before not powering off
It repairs, and/or, fault type is reported into producer by GPRS or WIFI.
Wherein, if after repeatedly adjusting, unit is still unavoidable from into fault protection scheme, then can pass through display
Terminal is shown or is broadcasted prompt tone, the mode of flash for prompting lamp reminds user to repair.For passing through WIFI or GPRS
Fault type can also be passed through GPRS or WIFI active reporting to producer, in order to producer by the unit to network with producer
Fault type is understood in advance, arranges personnel's on-site maintenance in time, promotes after-sale service quality.
In one possible implementation, as shown in figure 4, step S202, adjustment unit operating parameter after,
Method further includes：
Step S205, if the performance parameter of unit is not up to default capabilities parameter, user is prompted to repair, and/
Or, fault type is reported to producer by GPRS or WIFI.Wherein, performance parameter includes the leaving air temp of unit or reaches
Time needed for default leaving air temp.Wherein, in the case where having tended towards stability operation after unit is adjusted, it is still desirable to logical
The operating status of sensor monitoring unit is crossed, for example, the delivery temperature of monitoring unit, current leaving air temp, reach pre- and set out
Time needed for air temperature etc..With this come determine adjustment operating parameter after, the performance parameter of unit whether reach default capabilities ginseng
Whether number, the performance of unit can satisfy the basic use demand of user, use if it is not, needing to remind by display terminal
Family repairs, or passes through GPRS or WIFI active reporting to producer.
For example, unit is set as running in cooling mode with 26 degree by user, current indoor temperature is 30 degree.Then according to
The service ability of conventional power unit, the time that 26 degree of needs are reduced to from 30 degree is 5 minutes.It, may after unit adjusts operating parameter
Will lead to from 30 degree be reduced to 26 degree needed for the time it is elongated, for example, it may be possible to be 7 minutes.It in this case, is still to meet to use
Family demand.But if adjustment operating parameter after, temperature can not be reduced to 26 degree in preset duration, for example, 20 minutes all
26 degree can not be reduced to, then it is assumed that be unable to satisfy user demand.It then can be in the reliability and performance of unit using the implementation
Between choose equalization point, avoid only for the purpose of not triggering fault protection scheme, and the operating parameter of unit is carried out excessive
Adjustment, to influence the performance of unit, or even cannot meet the needs of users.Unit can be with comprehensive performance and reliability as a result,
Autonomous learning generates optimal operating parameter and is stored.User can also be prompted to carry out when needing to repair
Maintenance, is more flexible the work of unit, further satisfaction user demand.
In one possible implementation, as shown in figure 5, the embodiment of the present invention also provides a kind of adjustment unit operation ginseng
