In order to better understand the above technical scheme, in conjunction with appended figures and specific embodiments to upper Technical solution is stated to be described in detail.

Embodiment one

In embodiments of the present invention, as shown in Fig. 2, compressor and fluid reservoir junction are provided with temperature sensor Ti.

Fig. 3 is the flow chart of the compressor stop jumping prediction technique of the embodiment of the present invention.As shown in figure 3, the embodiment of the present invention Compressor stop jumping prediction technique, comprising the following steps:

S101: temperature sensor is obtained in the first object temperature at the first moment.

Wherein, the first object temperature at the first moment should be the first moment temperature sensor Ti collected temperature.

It should be noted that then entering compression when obtaining first object temperature of the temperature sensor Ti at the first moment The process of machine stop jumping prediction, but temperature sensor T1 is being obtained before the first object temperature at the first moment, it needs to air-conditioning Running environment is judged, to determine the limiting condition of operation of air conditioner.

The process for the limiting condition for determining operation of air conditioner is described below with reference to Fig. 4.

As shown in figure 4, obtaining temperature sensor before the first object temperature at the first moment, further includes:

S201: air-conditioning is obtained in first outdoor environment temperature and the first supply voltage at the first moment.

S202: according to the first outdoor environment temperature and the first supply voltage, the target limit work that air-conditioning is presently in is determined Condition.

Wherein, target limit operating condition is temperature extremes operating condition or voltage limit operating condition.

As a possible embodiments, as shown in figure 5, step S202 also may particularly include S212 and S222.

S212: first temperature difference between the first outdoor environment temperature and preset outdoor minimum environment temperature, judgement are obtained Whether first temperature difference is greater than the first preset temperature value, if it is greater than the first preset temperature value, it is determined that target limit operating condition is temperature Spend limiting condition.

S222: the first voltage obtained between the first supply voltage and preset supply voltage minimum value is poor, judges first Whether voltage difference is greater than the first preset voltage value, if it is greater than the first preset voltage value, it is determined that target limit operating condition is voltage Limiting condition.

That is, first obtaining first outdoor environment at the first moment before starting to carry out stop jumping prediction to compressor Temperature T_4,nowWith the first supply voltage U_now, then respectively according to preset outdoor minimum environment temperature T_minWith preset power supply electricity Press minimum value U_minTo the first outdoor environment temperature T_4,nowWith the first supply voltage U₁Judged.Specifically, it calculates and obtains first Outdoor environment temperature T_4,nowWith preset outdoor minimum environment temperature T_minBetween the first temperature difference (T_4,now-T_min), then judge First temperature difference (T_4,now-T_min) whether it is greater than the first preset temperature value, if the first temperature difference (T_4,now-T_min) default greater than first Temperature value, it is determined that target limit operating condition is temperature extremes operating condition；Meanwhile obtaining the first supply voltage U_nowWith preset power supply Voltage minimum U_minBetween the poor (U of first voltage_now-U_min), judge the poor (U of first voltage_now-U_min) whether it is greater than first in advance If voltage value, if the poor (U of first voltage_now-U_min) it is greater than the first preset voltage value, it is determined that target limit operating condition is voltage pole Limit operating condition.

Specifically, during the operation of the compressor, obtaining the first outdoor environment temperature T at the first moment_4,nowWith first Supply voltage U_now, respectively with preset outdoor minimum environment temperature T_minWith preset supply voltage minimum value U_minIt is compared, As the first outdoor environment temperature T_4,nowWith preset outdoor minimum environment temperature T_minBetween the first temperature difference (T_4,now-T_min) big When the first preset value, determine that compressor operates under temperature extremes operating condition, as the first supply voltage U_nowWith preset power supply electricity Press minimum value U_minPoor (the U of first voltage_now-U_min) be greater than the first preset voltage value when, determine that compressor operates in voltage limit Under operating condition, when identifying that compressor operates under temperature extremes operating condition or voltage limit operating condition, obtain temperature sensor Ti's First object temperature and the second target temperature, and compressor is presently according to first object temperature and the second target temperature Operation phase is identified, with the operation phase presently described according to compressor, predicts whether compressor occurs stop jumping.

Wherein, the first preset temperature value can be 2 DEG C, and the first preset voltage value can be 3V.

S102: tracing the temperature of temperature sensor, obtains temperature sensor in the second target temperature at the second moment Degree.

Wherein, the second target temperature is to meet the condition set under the different limiting condition of air-conditioning, and the second moment and the Target temperature on the one the smallest temperature sensor of moment time interval.

By Such analysis it is found that due to the protection act of overload protective device OLP occur it is excessively high or when electric current is excessive in temperature, Limiting condition can be then divided into temperature extremes operating condition and two kinds of voltage limit operating condition.

Therefore, the second target temperature can be divided into the second target temperature T under temperature extremes operating condition_{I, 2}With voltage limit work The second target temperature T under condition_{I, 4}。

According to one embodiment of present invention, as shown in fig. 6, under temperature extremes operating condition, temperature sensor is obtained the Second target temperature at two moment, comprising:

S311: since the previous moment at the first moment, n-th moment collected outdoor environment temperature is obtained, by N A moment collected outdoor environment temperature is compared with the first outdoor environment temperature.

Wherein, at the time of the n-th moment is earlier than the first moment, N is positive integer.

S312: if the difference of the outdoor environment temperature at n-th moment less than the first outdoor environment temperature and between the two For the second preset temperature value, then using the target temperature on n-th moment temperature sensor as the second target temperature value.

As an example it is assumed that the first moment was the i-th moment, then the first moment that the previous moment at the first moment starts is (i-1)-th moment, second moment were the i-th -2 moment ..., obtained the outdoor environment temperature T at the (i-1)-th moment respectively_4,(i-1), the The outdoor environment temperature T at i-2 moment_4,(i-2)..., the n-th moment is then collected into obtain outdoor environment temperature T_4,(i-N)With first Outdoor environment temperature T_4,nowIt is compared, if the outdoor environment temperature T at n-th moment_4,(i-N)Less than the first outdoor environment temperature Spend T_4,now, i.e. T_4,(i-N)< T_4,now, and difference between the two is the second preset temperature value, then by n-th moment temperature sensing Target temperature on device is as the second target temperature value.

Wherein, the second preset temperature value can be 2 DEG C.

Similarly, as shown in fig. 7, under voltage limit operating condition, temperature sensor is obtained in the second target temperature at the second moment Degree, comprising:

S321: since the previous moment at the first moment, n-th moment collected supply voltage is obtained, when by n-th Collected supply voltage is carved to be compared with the first supply voltage.

S322: if the difference of the supply voltage temperature at n-th moment less than the first supply voltage and between the two is the Two preset voltage values, then using the target temperature on n-th moment temperature sensor as the second target temperature value.

It should be understood that in embodiments of the present invention, the process of the second target temperature is obtained under voltage limit operating condition Identical as the process under temperature extremes operating condition, details are not described herein.

S103: according to first object temperature and the second target temperature, the operation phase that compressor is presently in is identified.

S104: whether the operation phase being presently according to compressor, prediction compressor occur stop jumping.

Specifically, the first outdoor environment temperature and the first power supply can be first passed through when needing to predict compressor stop jumping Voltage determines the limiting condition of operation of air conditioner, and the first object temperature at the first moment is then obtained according to temperature sensor Ti, Then the second target temperature is determined further according to current working condition, according to first object temperature and the second target temperature, identification pressure The operation phase that contracting machine is presently in predicts whether compressor occurs stop jumping further according to the operation phase that compressor is presently in.

The prediction technique of the embodiment of the present invention as a result, is detected by the temperature to compressor and fluid reservoir junction And identification, so as to be effectively predicted out whether compressor occurs stop jumping.

According to one embodiment of present invention, it when air-conditioning is in temperature extremes operating condition and voltage limit operating condition simultaneously, obtains Take temperature sensor after second target temperature at the second moment, as shown in Figure 8, further includes:

S401: the first time interval between temperature extremes operating condition corresponding first moment and the second moment is obtained.

S402: the second time interval between voltage limit operating condition corresponding first moment and the second moment is obtained.

It should be noted that, since outdoor environment increases, needing to increase indoor refrigeration in air conditioner refrigerating operational process Amount, therefore compressor may be operated in simultaneously under temperature extremes operating condition and under voltage limit operating condition, that is, outdoor temperature is higher have been reached To temperature extremes operating condition, meanwhile, reach voltage limit operating condition to increase refrigerating capacity compressor current and increase to, at this point, compression Machine had both worked in temperature extremes operating condition or had worked in voltage limit operating condition.

Specifically, according to the second moment of the second target temperature of the first moment and acquisition for obtaining first object temperature, divide It Huo Qu not temperature extremes operating condition and the corresponding first time interval t of voltage limit operating condition₁With the second time interval t₂.In other words, in temperature When spending limiting condition, first object temperature T is obtained_{I, 1}With the second target temperature T_{I, 2}Between first time interval t₁, in voltage When limiting condition, first object temperature T is obtained_{I, 3}With the second target temperature T_{I, 4}Between the second time interval t₂.Then basis First time interval t₁With the second time interval t₂Judged.

Wherein, according to above-mentioned analysis it is found that first time interval t₁It can be the first moment under temperature extremes operating condition and N Time span between a moment, the second time interval t₂Can under voltage limit operating condition the first moment and n-th moment it Between time span.

S403: first time interval is compared with the second time interval, if first time interval is greater than second Between be spaced, then control air-conditioning under temperature extremes operating condition, the operation phase be presently in compressor and is identified.

S404: if first time interval is less than or equal to the second time interval, air-conditioning is controlled in voltage limit work Under condition, the operation phase is presently in compressor and is identified.

Specifically, first time interval t is being determined₁With the second time interval t₂Afterwards, to first time interval t₁When with second Between be spaced t₂Time span be compared, if first time interval t₁Greater than the second time interval t₂, then air-conditioning is controlled in temperature It spends under limiting condition, the operation phase is presently in compressor and is identified, if first time interval t₁It is less than or equal to Second time interval t₂, then air-conditioning is controlled under voltage limit operating condition, and the operation phase is presently in compressor and is identified.

Prediction technique according to an embodiment of the present invention as a result, can be in simultaneously temperature extremes operating condition and voltage in air-conditioning When limiting condition, the main operating condition for influencing air-conditioning is determined, and then current to compressor according to the limiting condition determined The locating operation phase is identified.

S504: if the third temperature difference is less than or equal to the second preset temperature value, it is determined that compressor is currently at third Operation phase.

Wherein, be again at can the corresponding electric current model of active region for the electrical current of third operation phase instruction overload protective device In enclosing.

It should be noted that under temperature extremes operating condition and under voltage limit operating condition, according to first object temperature and second The process that target temperature identifies the operation phase that compressor is presently in is identical.In other words, under temperature extremes operating condition, make With first object temperature T_{I, 1}, the second target temperature T_{I, 2}With protection temperature threshold T_{Suc, t}Carry out the knowledge of the operation phase of compressor Not, under voltage limit operating condition, first object temperature T is used_{I, 3}, the second target temperature T_{I, 4}With protection temperature threshold T_{Suc, u}It carries out The identification of the operation phase of compressor.

Wherein, in embodiments of the present invention, the second preset temperature value can be 10 DEG C.

Below by taking temperature extremes operating condition as an example, to illustrate according to first object temperature and the second target temperature identification compressor The detailed process for the operation phase being presently in.

Under temperature extremes operating condition, first object temperature T is obtained_{I, 1}With the second target temperature T_{I, 2}, according to first object temperature Spend T_{I, 1}With the second target temperature T_{I, 2}Calculate the second temperature difference (T_{I, 1}-T_{I, 2}), second temperature difference and the second preset temperature value (10 DEG C) into Row compares, if second temperature difference is greater than the second preset temperature value, i.e. (T_{I, 1}-T_{I, 2}) 10 DEG C of >, it is determined that compressor is currently at Second operation phase, in the second operation phase, the electric current for flowing through compressor enters acting in U.T.C performance diagram for the first time In area, then this region, stop jumping will not occur for compressor, but indoor refrigerating capacity reduces；If the second temperature difference (T_{I, 1}-T_i,₂) be less than Or be equal to the second preset temperature value (10 DEG C), i.e. (T_{I, 1}-T_{I, 2})≤10 DEG C then further obtain first object temperature and protection The third temperature difference (T between temperature threshold_{I, 1}-T_{Suc, t}), if the third temperature difference (T_{I, 1}-T_{Suc, t}) it is greater than the second preset temperature value (10 DEG C), i.e. (T_{I, 1}-T_{Suc, t}) 10 DEG C of >, it is determined that compressor was currently at for the first operation phase, in the first operation phase, compressor Stop jumping will not centainly occur, if the third temperature difference (T_{I, 1}-T_{Suc, t}) be less than or equal to the second preset temperature value (10 DEG C), i.e., (T_{I, 1}-T_{Suc, t})≤10 DEG C, it is determined that compressor is currently at the third operation phase, in the third operation phase, flows through compressor Electric current be again introduced into U.T.C performance diagram can be in active region, then this region, stop jumping will occur for compressor.

According to one embodiment of present invention, as shown in Figure 10, after the operation phase that identification compressor is presently in, also Include:

S601: the third outdoor environment temperature and third power supply voltage at third moment are obtained.

Wherein, the third moment is spaced preset duration earlier than the first moment and between the first moment.In the embodiment of the present invention In, preset duration can be 5min, in other words, after identifying the operation phase that compressor is presently in, obtain the first moment it The third outdoor environment temperature T of first five minute_4,5minWith third power supply voltage U_5min。

S605: when identifying that compressor is currently at the third operation phase, if the first outdoor environment temperature is greater than the Three outdoor environment temperatures or the first supply voltage are greater than third power supply voltage, it is determined that stop jumping occurs at once for compressor.

That is, when compressor was in for the second operation phase, the can be entered by the second operation phase under given conditions Three operation phase, when compressor is in third operation extremely, then at the time of can further determining that stop jumping will occur for compressor.

It should be understood that passing through the third outdoor environment temperature T at third moment under temperature extremes operating condition_4,5minWith One outdoor environment temperature T_4,now, whether by the second operation phase will be entered the third operation phase to compressor, and in third Whether the operation phase, which will occur stop jumping, is judged, and under voltage limit operating condition, pass through the third power supply electricity at third moment Press U_5minWith the first supply voltage U_now, whether third operation phase, Yi Ji will be entered by the second operation phase to compressor Whether the third operation phase, which will occur stop jumping, is judged.
