If whether failure, which includes: incrementss, accounts for the ratio of history minimum average B configuration power consumption more than or equal to preset ratio value, it is determined that
The system failure；Wherein, incrementss=average power consumption-history minimum average B configuration power consumption；If incrementss account for history minimum average B configuration
The ratio of power consumption is less than preset ratio value, it is determined that system does not have failure.It will be appreciated that history minimum average B configuration power consumption is
Minimum value before current time, in the average power consumption of the system.System can be from the average power consumption after first time starts
Begin, record average power consumption, and when one new average power consumption of every record, it is compared with average power consumption before
Compared with, if this average power consumption be less than a upper average power consumption, carry out data cover, with this come determine history minimum average B configuration consume
Electricity.Each average power consumption can also be saved, and is needing to carry out average power consumption and history minimum average B configuration power consumption
When comparison, then from all data recorded, history minimum average B configuration power consumption is chosen.Both the above method is used equally for determining
History minimum average B configuration power consumption.
Wherein, average power consumption can be power consumption of the system in one hour.Preset time period can be by user according to reality
Border demand is determining, such as: preset time period can be 3 hours, 4 hours or 12 hours etc..Preset ratio value can be 9%.Work as increasing
When the ratio that dosage accounts for history minimum average B configuration power consumption is greater than or equal to 9%, illustrate being averaged in preset time period detected

Greatly, it can determine that as system failure.As a result, can according to simple data comparison, come determine system whether failure, and can basis
A variety of methods determine reference amount (history minimum average B configuration power consumption), determine that the method for failure is relatively simple and flexible.
In one possible implementation, as shown in figure 4, step S102, being averaged according to system in preset time period
Power consumption determines whether failure includes: system
Step S401, the rated energy consumption of system under full capacity is determined；
Step S402, average power consumption and rated energy consumption are compared, whether to determine system according to comparing result
Failure.
Wherein, average power consumption and rated energy consumption are compared, with according to comparing result determine system whether failure
If including: that average power consumption is greater than or equal to rated energy consumption, it is determined that the system failure；If average power consumption is less than specified
Power consumption, it is determined that system does not have failure.Wherein, rated energy consumption can be determined before factory by system, and marking is in system
On nameplate.As a result, in addition to above-mentioned implementation, can also be to determine according to the size relation of average power consumption and rated energy consumption
System whether failure, the method for increasing the determining system failure.
It will be appreciated that whether the method for failure is applied to system when being in full load condition to above-mentioned determining system, it is following
Method is applied to unit when being in low load condition, as shown in figure 5, step S103, according in the equipment of any one type, often
The power consumption of a equipment determines whether failure includes: system
Step S501, it determines in every kind of device type of system, the power consumption of each equipment；
Step S502, according in same device type, the size of the power consumption of each equipment and corresponding power consumption threshold value
Relationship determines in same device type, if there are equipment faults；
If there are equipment faults, it is determined that the system failure in step S503, same device type；
If in step S504, each device type, equipment fault is not present, it is determined that system fault-free.
Wherein, device type can be blower, water pump, compressor etc..If system there are 4 kinds of device types, need true respectively
In fixed every kind of device type, the power consumption of each equipment, and power consumption threshold value corresponding to every kind of device type is different, power consumption
Threshold value is related with device type.If there is in any one device type, there are failures at least one equipment, then it can determine system
Failure, if in each device type, equipment fault is not present, it is determined that system fault-free.Such as: if same device type is
Blower, and the system opens 5 blowers under low load condition, if blower A there are failure, can determine whether that this sets for blower
There are failures for standby type, then there are failures for system.It will be appreciated that the equipment in Fig. 5 is the equipment of unlatching, but that opens sets
The all devices (therefore affairs that should be kept secret group is in low load condition) of standby not equivalent to system.
Specifically, step S502, according in same device type, the power consumption of each equipment and corresponding power consumption threshold value
Size relation, determine in same device type, if if including: the power consumption of each equipment in power consumption there are equipment fault
Fluctuating range above and below threshold value is respectively less than or is equal to corresponding default fluctuating range, it is determined that in same device type, does not set
Standby failure；If fluctuating range of the power consumption of at least one equipment above and below power consumption threshold value is greater than default fluctuating range, really
In fixed same device type, there are equipment faults.
It will be appreciated that the power consumption difference of repeatable more each equipment, to determine whether there is equipment fault.Because of consumption
Power threshold can determine according to the history run of system, and since environmental factor etc. influences, the power consumption of each equipment
There may be certain differences, and using power consumption threshold value as central axes, on it lower fluctuation.But fluctuating range should be less than or be equal to
Default fluctuating range.If the fluctuating range of the power consumption of a certain equipment is greater than default fluctuating range, the equipment can determine
Power consumption exists abnormal, i.e. the power consumption of the equipment is larger or the power consumption of the equipment is minimum.If power consumption no significant difference,
It then can determine the power consumption of each equipment compared with historical data, if ever-increasing state to be in, when increment is more than pre-
If when threshold value, then can determine the system failure.As a result, can when system is in underrun state, determine system whether failure,
It reminds the user that and carries out malfunction elimination in time, and maintenance or more exchange device, to guarantee the stable operation of unit.
Based on this, in the system that determines whether after failure, method further include: if the system failure, issue prompt information；Its
In, prompt information is for prompting user to carry out malfunction elimination.Prompt information can be indicator light flashing or broadcast voice information.
It should be noted that when system is in underrun state, in one possible implementation, such as Fig. 6
It is shown, in step S103, the equipment according to any one type, the power consumption of each equipment determine system whether failure it
Afterwards, method further include:
Step S601, if it is determined that the system failure, then position incipient fault equipment；
Step S602, the operation weight of incipient fault equipment is adjusted, to reduce energy consumption.

Then positioning incipient fault equipment includes:
Step S701, determine that there are the device types of equipment fault；
Step S702, all devices in device type are controlled and press the operation of bisearch algorithm sequence alternate within a preset time；
And determine the power consumption situation of change of system；
Step S703, power consumption situation of change is compared and analyzed, positions incipient fault equipment.
In one possible implementation, the device type there are equipment fault can determine by method shown in fig. 5,
For example, device type is blower, then the blower of positioning incipient fault is needed, then all devices in controllable device type are default
It is run in time by bisearch algorithm sequence alternate, and the power consumption situation of change of comparison system.For example, system has 5 blowers, point
Not Wei A, B, C, D, E, then can control first blower A, B, C operation, then control blower B, C, D operation, then control blower C, D, E fortune
Row, can traverse all combinations, and carries out big data and compare analysis, to position incipient fault according to power consumption situation of change
Equipment.
In one possible implementation, as shown in figure 8, the operation weight of step S602, adjustment incipient fault equipment
Include:
Step S802, determine that the operation of incipient fault equipment is weighed according to the runing time of incipient fault equipment and performance parameter
Weight；
Wherein, at runtime between it is identical with the runing time of remaining equipment in device type where incipient fault equipment
In the case of, performance parameter is bigger, and operation weight is lower；Wherein, performance parameter includes: operation power, power consumption.It should be noted
It is that incipient fault equipment represents the biggish equipment of energy consumption, then can reduces the operation weight of incipient fault equipment, is positioning potential event
Before hindering equipment, in same device type, the operation weight of each equipment is identical.After determining incipient fault equipment, it can be reduced
Weight.Specific weight can be determined according to the runing time and performance parameter of incipient fault equipment.It will be appreciated that when running
Between it is identical when, performance parameter is bigger, and the power consumption that represents is bigger, then weight can be lower, i.e., reduction incipient fault equipment operation it is general
Rate, until it is repaired.If runing time is different, for example, the runing time of remaining normal device is longer, and this incipient fault
Equipment also not running can control this incipient fault equipment to run then for remaining equipment is protected.System energy consumption can be reduced as a result,
Reach energy saving technical effect.
