The current running parameter of group;Determined whether to execute masking operation according to running parameter and strain parameter;If it is, triggering master control
The control of device 2 shielding failure-frequency point processed.
It can shield in the actual operational process of unit it is easier that the compressor of ess-strain problem occurs in pipeline as a result,
Running frequency, compared to the prior art for, improve shielding failure-frequency point accuracy rate, avoid pipeline and break
It splits, to reach protection unit, so that the purpose of unit reliability service.
In one possible implementation, as shown in Fig. 2, unit can be air conditioner, strain parameter includes: that pipeline is answered
Variable element, strain detecting module 1 are as follows: strain transducer is used for signal piping strain parameter positioned at the sample tube road of unit.
Strain transducer is indicated with A1, A2, An in Fig. 2, that is to say, that can according to the actual situation (performance of unit, piping material,
Adaptability to changes) etc. determine strain transducer quantity.And the interval location between strain transducer can also according to the actual situation into
Row setting.Wherein, the air entry of sample pipeline and compressor connects, and the diameter of sample pipeline is less than or equal to preset diameters
(such as: 6mm).Sample pipeline preferentially chooses the slim pipe diameter that ess-strain is easy exceeded (vibrating at air entry larger), can be into one
Step improves the accuracy of shielding, achievees the purpose that utmostly to protect each pipeline of unit to the greatest extent.
In one possible implementation, as shown in Fig. 2, strain parameter includes: displacement parameter, strain detecting module 1
Are as follows: displacement sensor, in the air entry of the compressor of unit, for determining displacement parameter.In Fig. 2, displacement sensor
It is indicated with B1.Similarly, the present invention does not limit the quantity of displacement sensor.
It should be noted that in the possible implementation of both the above, it is corresponding when strain parameter is pipeline strain parameter
One preset failure threshold value, when strain parameter is displacement parameter, a corresponding preset failure threshold value.Two preset failure threshold values
It is to be not desired to close completely.Only strain parameter exceed preset failure threshold value when, can trigger data center judge whether to shield therefore
Hinder Frequency point, when only displacement parameter exceeds preset failure threshold value, also can trigger data center and judge whether that failure-frequency need to be shielded
When point or the two all exceed corresponding preset failure threshold value, it can trigger data center and shield failure-frequency point.Moreover, can also
Shielding event is determined the need for according to the relationship of the corresponding preset failure threshold value of remaining parameter that can represent strain parameter
Hinder Frequency point, the invention is not limited in this regard.
In one possible implementation, running parameter includes at least following one: the current running frequency of compressor
And the running state parameter of unit.Master controller 2 is also used to determining strain parameter beyond corresponding preset failure threshold value
Afterwards, obtain the running state parameter of unit (load 5 that master controller and unit are expressed as in Fig. 2 connects);It is also used to basis
Running state parameter judges whether unit is currently run normal, if it is, running state parameter is sent to data center, such as
Fruit is no, then controls unit and issue prompt information, to prompt user's detection load 5 relevant to running state parameter.Wherein, it runs
State parameter includes: refrigerant state parameter, fan condition parameter.Wherein, refrigerant state parameter can be according to system pressure difference and pipe
Temperature determines.Fan condition parameter can be the running frequency of blower, wind speed etc..System pressure difference, that is, system high pressure and system low-voltage it
Difference, system high pressure and system low-voltage can be determined according to high pressure sensor and low pressure sensor respectively.This implementation considers
When analyzing a certain key variables, the consistency of remaining variables should be kept, remaining influence factor can be excluded as a result, only analysis is answered
Variable element, so that judging result is more accurate.
In one possible implementation, as shown in Fig. 2, data center 3, is also used to according to running parameter and strain ginseng
Number determines fault type;When failure-frequency point and default screening frequencies point difference within a preset range, determine that fault type is

It covers the difference of Frequency point not within a preset range, then unit durability calculating is carried out according to the strain parameter obtained in real time, and according to
The result that service life calculates determines whether to execute masking operation.Data center 3 is also used in failure-frequency point and the default shielding
The difference of Frequency point not within a preset range when, determine the strain parameter that obtains in real time it is no be more than setting value;If being more than, execute
Masking operation.
Wherein, as shown in Fig. 2, unit can be attached with data center 3 by any one following mode: GPRS
(General Packet Radio Service, general packet radio service technology), WLAN (Wireless Local Area
Networks, WLAN).It can carry out wireless data transmission therebetween as a result,.The effect of data center 3 is according to work
Make parameter and strain parameter carries out numerical simulation analysis, and determines whether to execute masking operation.And it is default in this implementation
It may range within 0 to ± 2HZ.Specific numerical simulation analysis process can be, and research staff counts the big of a large amount of units
Data cases, and a set of judgment criteria is designed according to the corresponding relationship of failure-frequency point, strain parameter, running parameter in advance, according to
It is judged that standard judges whether relevant data meet predetermined condition, to determine when strain parameter exceeds preset failure threshold value,
Whether corresponding failure-frequency point should shield.It should be noted that strain parameter only shields event beyond preset failure threshold value
Hinder a prerequisite (it can be appreciated that necessary condition) of Frequency point, but the Frequency point for whether shielding a compressor is one
The important decision of item shields failure-frequency point if only because exception occurs in current strain parameter, and it is easy to appear accidentally
The case where shielding, will affect the normal operation of unit in the future, influence the performance of unit.So master controller is needed into data
The heart 3 sends running parameter and strain parameter so that data center 3 carry out it is a series of automatically analyze, and decide whether to execute
Masking operation.Wherein, human-computer interaction process can also be increased, by research staff in real time or data according to feedback at times into
Row manual analysis, as a result, while avoiding pipeline exceeded in response to stress-strain and failing, so that the final result of decision more accords with
Current situation is closed, the accuracy rate of shielding is further increased.Data center 3 can be after determining execution masking operation, by program
Upgrade command is sent to master controller;Wherein, program upgrade command is used to indicate shielding failure-frequency point.Specifically, main control
For device 2 after upgrade procedure, the drive control device 4 for controlling compressor carries out program upgrading, and shields failure-frequency point.Data center
Program upgrade command directly can also be sent to drive control device 4 by 3, carry out program upgrading to control drive control device 4.
