If compressor is in frequent start-stop state, then the electric current Value Data for flowing through compressor will also have fluctuation,
Otherwise electric current should be more steady, therefore can be to judge compressor by the fluctuation situation for the electric current Value Data for detecting compressor
It is no to be in frequent start-stop state.
After air-conditioning start, when compressor opens t (such as 0<t<3) during the second, by current detection circuit per TsSecond collection 1 time
Electric current on power firestreak, and continuous storage its current value for collecting, use I1、I2……InThe current value collected is represented,
Three kinds of software algorithms are established in MCU (Microcontroller Unit, micro-control unit) to judge compressor whether in frequency
Numerous start-stop state, algorithm thinking are as follows：Take T1The current value collected in second, uses Ir、Ir+1、Ir+2……Ir+k(r >=1, k >=2)
Represent, and
Preparatory condition one：
(1) to Ir、Ir+1、Ir+2……Ir+k(r >=1, k >=2) current value, is compared by program, finds out satisfaction successively
The current value I of following condition (formula is 1.)MSequence：
Ii-1≤IiAnd Ii≥Ii+1(r ＜ i ＜ r+k) 1.
Such IiIt is exactly IMElement in sequence, and make IM1To meet first I of formula 1. conditioni, the like, obtain
Go out IMElement is I in sequenceM1、IM2……IMa(a ＜ k).
(2) the current value I for meeting following condition (formula is 2.) is found out againNSequence：
Ij-1≥IjAnd Ij≤Ij+1(r ＜ j ＜ r+k) 2.

Go out INElement is I in sequenceN1、IN2……INb(b ＜ k)；
(3) to IM、INThe following intersection of sequence progress subtracts each other (formula is 3.) and can obtain Δ IMNSequence：
ΔIMNb=IMa-INb ③
Draw Δ IMNElement is Δ I in sequenceMN1、ΔIMN2……ΔIMNb(b ＜ k).
(4) Δ I is calculatedMNThe average value of sequence
Preparatory condition two：
(1) T is calculated1Average current value in second
(2) I and then is respectively used againr、Ir+1、Ir+2……Ir+kAverage current value is subtracted successivelyI is obtained after taking absolute value again
Sequence, its sequential element are Ir′、Ir+1′、Ir+2′……Ir+k', i.e.,：
(3) each element in I ' sequences is judged, the number for obtaining element of its value more than predetermined threshold value A is N；
Preparatory condition three：
The maximum I of compressor normal operating current is determined by current value when surveying compressor normal operationMAXMost
Small value IMIN；To the current value I of collectionr、Ir+1、Ir+2……Ir+k(r >=1, k >=2) carry out following condition (formula is 7.) and judged：
IMAX≤Ir+i≤IMIN(i∈[0,k]) ⑦
Find out all numbers for meeting the current value of condition 7., it is assumed that be Q, then calculate the percentage of its shared sumFor example：If during compressor normal operation, its P% >=90%；If compressor is in frequent start-stop shape
During state, P%≤50%, as long as so setting rational threshold value, it is possible to judge the frequency of compressor according to above-mentioned percentage
Numerous start-stop state.
It can be determined with reference to three of the above algorithm, if in continuous S (S>1) secondary T1The current value collected in second is equal
Following three conditions can be met simultaneously：1) current averageMore than predetermined current average value threshold value C, 2) electric current collected
Average current value is individually subtracted in valueAbsolute value be more than predetermined threshold value A number, more than default number threshold value N, 3) meet bar
The number Q of the current value of part 7. accounts for the ratio of total current value number, less than preset ratio threshold value P%, then judges that compressor is in
Frequent start-stop state, and compressor is protected.
Wherein, current average threshold value C, number threshold value N and preset ratio threshold value P% are judgement constant value, and this hair
Bright above-mentioned parameters Ts、T1, S etc. can slightly adjust according to different air conditioner type classifications.
In addition to judging high frequent start-stop above by detection electric current, it can also be detected by using identical method
Working voltage, power judge high frequent start-stop state.
The embodiment of the present invention carries out protection control to the compressor, specifically includes：Close the compressor, and accumulative guarantor
Protect the number of control；The compressor is opened after the second preset time is closed.
After the embodiment of the present invention carries out the step of protection control to the compressor, in addition to：In the accumulative guarantor
After the number of shield control is more than default frequency threshold value, stop operation of air conditioner, and carry out failure prompting.
That is, the present invention carries out the number of protection control by recording to the compressor, and in the 3rd preset time period
After the number is more than default frequency threshold value, stop operation of air conditioner, and carry out failure prompting.
That is, it is pre- then to close the compressor second when judging that compressor is in frequent start-stop state by the present invention
Fix time, while record the number for the compressor protect control, if in the 3rd preset time period, compressor is protected
After the number of shield control is more than default frequency threshold value, just stop operation of air conditioner, and carry out failure prompting, compressed with effective protection
Machine.
