Or other step or units that equipment is intrinsic.
Fig. 1 is the method schematic diagram of an embodiment of compressor exhaust temperature detection value correcting method provided by the invention.
As shown in Figure 1, according to one embodiment of present invention, the compressor exhaust temperature detection value correcting method is at least
Including step S110, step S120 and step S130.
Whether step S110, detection unit there is high voltage protective failure.
In a specific embodiment, whether the pressure sensor for detecting unit disconnects, when the pressure sensor is disconnected
When opening, determine that high voltage protective failure occurs in the unit.Units' installation has pressure sensor, and the pressure of unit passes under normal circumstances
Sensor is closure, if pressure is too high, such as pressure reaches scheduled pressure value, and pressure sensor can disconnect automatically, therefore is examined
Whether measuring pressure sensor disconnects, and when pressure sensor disconnects, determines that high voltage protective failure occurs in unit.
Step S120, when detect there is high voltage protective failure when, judge whether the delivery temperature detected value of unit reaches
Set temperature threshold value.
The case where causing unit to open high voltage protective, first is that real high voltage protective caused by unit high pressure, second is that due to
Exhaust high temperature, unit cannot handle exhaust high temperature in time, indirectly caused high voltage protective.If the delivery temperature detected at this time
Exhaust high temperature (preset temperature threshold) is had reached, illustrates it is not caused by delivery temperature, is genuine caused by the real high pressure of unit
High voltage protective does not need then to be corrected delivery temperature detected value；If the delivery temperature detected at this time is also not up to
Exhaust high temperature (preset temperature threshold) illustrates that high voltage protective failure at this time is needed caused by delivery temperature detected value is relatively low
The delivery temperature detected is corrected.If the delivery temperature detected value reaches the set temperature threshold value, do not need
The delivery temperature detected value is corrected.
Step S130, if the delivery temperature detected value is not up to the set temperature threshold value, to the delivery temperature
Detected value is corrected.
It in a specific embodiment, can be according to setting penalty coefficient and current environmental temperature to the delivery temperature
Detected value is corrected.Fig. 2 is the one of the step of being corrected to the delivery temperature detected value according to an embodiment of the present invention
The flow diagram of kind specific embodiment.
As shown in Fig. 2, in a specific embodiment, step S130 includes step S131 and step S132.
Step S131, according to the delivery temperature detected value and the temperature gap of current environmental temperature and setting penalty coefficient
Ratio, determine delivery temperature offset.
The sum of the delivery temperature detected value and the delivery temperature offset are determined as delivery temperature by step S132
Corrected value.
In the normal situation of exhaust gas temperature sensor, the relatively low main cause of delivery temperature detected value include temperature sensor with
Heat transfer is bad between exhaust pipe or delivery temperature test point is too serious to air heat dissipation, so delivery temperature offset needs
Consider the deviation of delivery temperature detected value and environment temperature, in a specific embodiment, definition: delivery temperature offset
=(delivery temperature detected value-environment temperature)/setting penalty coefficient, for example, can be with every 30 DEG C of delivery temperature detected values and environment
1 DEG C of the temperature difference compensation of temperature, then set a=30 DEG C of penalty coefficient；Definition: delivery temperature=delivery temperature detected value+exhaust temperature
Offset is spent, as long as offset is suitable, after temperature-compensating is exhausted, unit can be operated normally.
Fig. 3 is the method signal of another embodiment of compressor exhaust temperature detection value correcting method provided by the invention
Figure.As shown in figure 3, based on the above embodiment, judging that the delivery temperature detected value is not up to the set temperature threshold value
In the case of, it further include step S121 before being corrected (step S130) to the delivery temperature detected value.
Step S121 judges whether to carry out overcorrect to the delivery temperature detected value, if so, to the setting
Penalty coefficient is modified, with according to the revised setting penalty coefficient and current environmental temperature, to the delivery temperature
Detected value is corrected.
Since the heat dispersal situations of every unit are inconsistent, so also needing to be automatically adjusted setting penalty coefficient.In
In a kind of specific embodiment, if method of adjustment is that can also report high voltage protective failure after last time compensation, need to increase compensation
The setting penalty coefficient is reduced setting value by value, for example, reducing 1 DEG C.For example, calculating delivery temperature offset for the first time
Afterwards, enter high voltage protective again second, illustrate that the offset calculated for the first time is too small, at this time subtract setting penalty coefficient
Small setting value, dividend is constant, and divisor reduces, and the chamber of commerce increases, and the delivery temperature offset calculated just will increase, if next
It is again introduced into high voltage protective, setting penalty coefficient continues to reduce, and delivery temperature offset continues to increase, and eventually finds one and puts down
Weigh point, exhaust high temperature control is run before high voltage protective, and then operate normally unit, guarantees that user uses to greatest extent.
Technical solution of the present invention to clearly illustrate, below again with a specific embodiment to air supply velocity provided by the invention
Determine that the execution process of method is described.
Fig. 4 is the method signal of a specific embodiment of compressor exhaust temperature detection value correcting method provided by the invention
Figure.It include step S210~step S270 in embodiment as shown in Figure 4.
Step S210 acquires the value of each sensor after unit is opened.
Step S220, judges whether unit reports high voltage protective failure, if so, S230 is thened follow the steps, if it is not, then detection machine
Other failures of group.
Step S230, if unit report high voltage protective failure, detects whether delivery temperature reaches set temperature threshold value, that is, examine
Survey whether delivery temperature reaches exhaust high temperature control；If so, detection other failures of unit, if it is not, thening follow the steps S240.
Step S240, if delivery temperature reaches exhaust high temperature control, according to delivery temperature detected value and environment temperature
The ratio of the temperature difference and setting penalty coefficient a obtain delivery temperature offset, and are next executing step S240.
Step S250 is corrected delivery temperature detected value according to obtained delivery temperature offset, that is, exhaust temperature
Degree=delivery temperature detected value+delivery temperature offset.
Step S260, if unit reports high voltage protective failure again after correction, being modified to setting penalty coefficient a (will
Set penalty coefficient and reduce setting value for example, a=a-1), to be corrected again to delivery temperature detected value.
Fig. 5 is the structural schematic diagram of an embodiment of compressor exhaust temperature detected value means for correcting provided by the invention.
As shown in figure 5, the delivery temperature detected value means for correcting 100 includes: detection unit 110, judging unit 120 and correction unit
130。
Wherein, detection unit 110 is for detecting whether unit high voltage protective failure occurs；Judging unit 120 is for working as institute
When stating detection unit and detecting that high voltage protective failure occurs in the unit, judge whether the delivery temperature detected value of the unit reaches
To set temperature threshold value；If correction unit 130 judges that the delivery temperature detected value is not up to described for the judging unit
Set temperature threshold value is then corrected the delivery temperature detected value.
In a specific embodiment, whether the pressure sensor that detection unit 110 detects unit disconnects, when the pressure
When force snesor disconnects, determine that high voltage protective failure occurs in the unit.Units' installation has pressure sensor, under normal circumstances machine
The pressure sensor of group is closure, if pressure is too high, such as pressure reaches scheduled pressure value, and pressure sensor can be from dynamic circuit breaker
It opens, therefore detects whether pressure sensor disconnects, when pressure sensor disconnects, determine that high voltage protective failure occurs in unit.
Judging unit 120 judges whether the delivery temperature detected value of the unit reaches set temperature threshold value.Specifically, it leads
The case where causing unit to open high voltage protective, first is that real high voltage protective caused by unit high pressure, second is that due to exhaust high temperature, machine
Group cannot handle exhaust high temperature in time, indirectly caused high voltage protective.If the delivery temperature detected at this time has reached exhaust
High temperature (preset temperature threshold) illustrates it is not caused by delivery temperature, is genuine high voltage protective caused by the real high pressure of unit, then
It does not need to be corrected delivery temperature detected value；If it is (pre- that the delivery temperature detected at this time is also not up to exhaust high temperature
If temperature threshold), illustrate that high voltage protective failure at this time is to need caused by delivery temperature detected value is relatively low to the row detected
Temperature degree is corrected.If the delivery temperature detected value reaches the set temperature threshold value, do not need to the exhaust temperature
Degree detected value is corrected.
The correction unit 130 can specifically examine the delivery temperature according to setting penalty coefficient and current environmental temperature
Measured value is corrected.Fig. 6 is the structural schematic diagram of a specific embodiment of correction unit according to an embodiment of the present invention.Such as figure
Shown in 6, correction unit 130 includes the first determination unit 131 and the second determination unit 132.
First determination unit 131 be used for according to the delivery temperature detected value and the temperature gap of current environmental temperature with set
The ratio for determining penalty coefficient determines delivery temperature offset；Second determination unit 132 be used for by the delivery temperature detected value with
The sum of described delivery temperature offset, is determined as delivery temperature corrected value.
Specifically, in the normal situation of exhaust gas temperature sensor, the relatively low main cause of delivery temperature detected value includes temperature
Heat transfer is bad between sensor and exhaust pipe or delivery temperature test point is too serious to air heat dissipation, so delivery temperature
Offset needs to consider the deviation of delivery temperature detected value and environment temperature.First determination unit 131 is according to the delivery temperature
The ratio of detected value and the temperature gap of current environmental temperature and setting penalty coefficient, determines delivery temperature offset, defines: row
Gas temperature compensation value=(delivery temperature detected value-environment temperature)/setting penalty coefficient, for example, can be with every 30 DEG C of delivery temperatures
Detected value and 1 DEG C of the temperature difference compensation of environment temperature, then set a=30 DEG C of penalty coefficient；Second determination unit 132 is by the exhaust
The sum of temperature detection value and the delivery temperature offset are determined as delivery temperature corrected value, definition: delivery temperature=exhaust temperature
Detected value+delivery temperature offset is spent, as long as offset is suitable, after temperature-compensating is exhausted, unit can be operated normally.
Further, the correction unit 130 is also used to: before being corrected to the delivery temperature detected value, being sentenced
It is disconnected whether overcorrect have been carried out to the delivery temperature detected value, if so, being modified to the setting penalty coefficient.
Since the heat dispersal situations of every unit are inconsistent, so also needing to be automatically adjusted setting penalty coefficient.School
Positive unit 130 is also used to: before being corrected to the delivery temperature detected value, being judged whether to the delivery temperature
Detected value carries out overcorrect, if so, being modified to the setting penalty coefficient.If modification method is last time, compensation is gone back later
High voltage protective failure can be reported, then needs to increase offset, the setting penalty coefficient is reduced into setting value, for example, reducing 1 DEG C.
For example, entering high voltage protective again for the second time after calculating delivery temperature offset for the first time, illustrate the benefit calculated for the first time
It is too small to repay value, setting penalty coefficient is reduced into setting value at this time, dividend is constant, and divisor reduces, and the chamber of commerce increases, and calculates
Delivery temperature offset just will increase, if being again introduced into high voltage protective next time, setting penalty coefficient continue to reduce, delivery temperature
Offset continues to increase, and eventually finds an equalization point, exhaust high temperature control is run before high voltage protective, and then make unit just
Often operation guarantees that user uses to greatest extent.
