Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, to the technical side in the embodiment of the present inventionCase is clearly and completely described, and obviously, described embodiment is only one of the present inventionDivide embodiment, instead of whole embodiment. Based on the embodiment in the present invention, this area is generalLogical technical staff is not making the every other embodiment obtaining under creative work prerequisite,All belong to the scope of protection of the invention.
The all embodiment of the present invention can be applicable in air-conditioning, concrete, and this air-conditioning comprises off-premises stationAnd indoor set, and indoor set comprises M electric expansion valve, wherein M is more than or equal to 2.Example, this air-conditioning can be not cooling-down air conditioner of the dehumidifying shown in Fig. 1, indoor at this air-conditioningIn machine, there are 2 electric expansion valves. Air-conditioner outdoor unit in above-mentioned air-conditioning can adopt the present invention realExecute the aperture control method of the electric expansion valve that example provides, remove to control M electronics in indoor setAny one aperture of expansion valve.
The aperture controlling party of a kind of electric expansion valve that as shown in Figure 2, the embodiment of the present invention providesMethod flow chart. Concrete, the aperture control method of this electric expansion valve is applied to air-conditioner outdoor unit,Be that the method can be carried out at air-conditioner outdoor unit.
As shown in Figure 2, the aperture control method flow process of this electric expansion valve comprises:
Step 201, air-conditioner outdoor unit obtains the target opening value of the first electric expansion valve;
Step 202, generates communication information, and described communication information comprises and accounts for a N continuous byteAperture control information, described aperture control information comprises and accounts for described first of a continuous s bitThe mark of electric expansion valve and the target that accounts for described first electric expansion valve of a continuous t bit are openedDegree value, wherein, s is the least number of bits that can write M, t is for can write a described M electronicsThe least number of bits of maximum opening value in expansion valve.
Step 203, sends described communication information to described indoor apparatus of air conditioner.
In above-mentioned steps, air-conditioner outdoor unit is for controlling M electronics of indoor apparatus of air conditionerThe aperture of expansion valve, can adopt above-mentioned for any in this M electric expansion valveStep, controls its aperture.
Further, (be above-mentioned steps at the target opening value that obtains the first electric expansion valve101) before, above-mentioned control method can also comprise: what air-conditioner outdoor unit also will be according to air-conditioningThe dial-up value of the indoor set in when operation start, determines the machine type of air-conditioning. Wherein, air-conditioningIn the time of start operation, indoor apparatus of air conditioner can send to air-conditioner outdoor unit by dial-up value, outside air conditioning chamberMachine, according to the dial-up value receiving, is determined the machine type of air-conditioning.
If the machine type of air-conditioning is non-not cool-down dehumidification air-conditioning type, air-conditioner outdoor unit can be straightConnect the opening value of 1 electric expansion valve of buffer area buffer memory is sent to indoor apparatus of air conditioner.
If the machine type of air-conditioning is cool-down dehumidification air-conditioning type not, air-conditioner outdoor unit need rightThe aperture control information of the M of an indoor apparatus of air conditioner electric expansion valve is upgraded.
In step 201, obtain the target opening value of the first electric expansion valve.
Indoor apparatus of air conditioner comprises M electric expansion valve, and described the first electric expansion valve is instituteState any one electric expansion valve that needs to upgrade aperture in M electric expansion valve. Wherein,The target opening value of the first electric expansion valve refers to what this first electric expansion valve will be updated toOpening value. Example, opening value when two electric expansion valves starts of A, B is all 8%,Because air-conditioning system operation needs, A electronic expansion valve opening value need to be adjusted to 10%, that, A electric expansion valve is the first electric expansion valve, and correspondingly, 10% is the first electronicsThe target opening value of expansion valve.
The acquisition methods of the target opening value of the first expansion valve in this step can have multiple. RatioAs, can be that indoor air conditioner feeds back to outdoor air-conditioner; Also can be outdoor air-conditioner rootGet the target opening value of the first electric expansion valve according to the ruuning situation of air-conditioning system; At thisIn bright embodiment, the acquisition methods of the target opening value to the first electric expansion valve does not do concreteLimit.
Get the first electronics with air-conditioner outdoor unit according to the ruuning situation of air-conditioning system below swollenThe target opening value of swollen valve is example, and the concrete air-conditioner outdoor unit of introducing obtains the first electric expansion valveThe method of target opening value:
Whether the aperture that judges an electric expansion valve in a described M electric expansion valve needs moreNewly, particularly, air-conditioner outdoor unit divides the M of buffer area buffer memory electronic expansion valve opening valueDo not scan, determine an electric expansion valve in M the electric expansion valve that buffer area changesWhether two corresponding opening values are consistent. If determine two opening values corresponding to this electric expansion valveInconsistent, the opening value of determining this electric expansion valve needs to upgrade, and this electric expansion valve is theOne electric expansion valve.
Wherein, two opening values that each electric expansion valve is corresponding are respectively the first opening value andTwo opening values, the corresponding different time points of each opening value is cached to the opening of electronic expansion of buffer areaDegree value, such as time point corresponding to, the first opening value 21: 35: 22, the second apertureTime point corresponding to value is 21: 36: 42.
Further, the time point that the first opening value is corresponding and the difference of current time are less than secondThe time point that opening value is corresponding and the difference of current point in time. Such as, the first opening value is correspondingTime point 21: 35: 42, the time point that the second opening value is corresponding is 21: 36 22Second, current time is 21: 36: 52, can determine the corresponding time of the first opening valuePoint is 10 seconds with the difference of current time, the time point that the second opening value is corresponding and current timeDifference be 30 seconds.
Further, if air-conditioner outdoor unit determine in M electric expansion valve of buffer area buffer memory,Two opening values of first electric expansion valve are inconsistent, determine first electric expansion valveAperture needs to upgrade, and first electric expansion valve is defined as to the first electric expansion valve, will simultaneouslyThe first opening value of first electric expansion valve is defined as target opening value. Such as, first electricityThe first opening value of sub-expansion valve is that the second opening value of 20%, the first electric expansion valve is30%, because the first corresponding opening value and second opening value of first electric expansion valve differCause, the first opening value can be defined as to the target opening value of the first electric expansion valve.
If air-conditioner outdoor unit is determined first electricity in M electric expansion valve of buffer area buffer memoryThe aperture of sub-expansion valve does not need to upgrade, and can sequentially judge in M electric expansion valveWhether the aperture of second electric expansion valve needs to upgrade. Particularly, when second electronic expansionWhen two opening values of valve are inconsistent, determine that the opening value of second electric expansion valve needs moreNewly, second electric expansion valve is defined as to the first electric expansion valve, simultaneously by second electronicsThe first opening value of expansion valve is defined as target opening value.
If air-conditioner outdoor unit determines in M electric expansion valve of buffer area buffer memory, first,Two opening values of two electric expansion valves are inconsistent, determine first, second electronic expansionThe opening value of valve has renewal, first, second electric expansion valve is all defined as to the first electricitySub-expansion valve, and the first opening value of first, second electric expansion valve is distributed and is defined asTarget opening value, due to determine the first electric expansion valve correspondence two electric expansion valves,Can sort according to the sequence number of electric expansion valve, such as, can be by first electronic expansionValve is arranged as primary the first electric expansion valve, and second electric expansion valve is arranged as to secondThe first electric expansion valve of position; Also second electric expansion valve can be arranged as to primaryOne electric expansion valve, is arranged as deputy the first electronic expansion by the first each and every one electronic expansionValve; In the embodiment of the present invention, to determine how many first electronics from M electric expansion valveThe quantity of expansion valve is not done concrete restriction, simultaneously to the arrangement of multiple the first electric expansion valves timeOrder is not done concrete restriction yet.
In above-described embodiment, the first electric expansion valve getting is in M electric expansion valveNeed an electric expansion valve of the aperture of upgrading.
In step 202, generate aperture control information. This aperture control information accounts for N continuousIndividual byte, comprises the mark of the first electric expansion valve that accounts for a continuous s bit and accounts for continuous tThe target opening value of the first electric expansion valve of bit.
In actual applications, between air-conditioner outdoor unit and indoor apparatus of air conditioner, communication information is according to logicalNews agreement generates, and as shown in Figure 3, it can comprise U byte (8U bit).In embodiments of the present invention, aperture control information has only taken the byte of the N in communication information,Certainly communication information can also comprise other information, and other information and the embodiment of the present invention withoutClose, therefore do not add restriction at this.
Aperture control information is arbitrary for controlling in M electric expansion valve of indoor apparatus of air conditionerIndividual aperture, accounts for N byte (8N bit) wherein, for example: and as shown in Figure 3,N byte accounts for a part of byte in U byte, can be that i byte is to i+NByte. This aperture control information comprises mark and first electric expansion valve of the first electric expansion valveTarget opening value.
Wherein, the mark of the first electric expansion valve is used for representing that this first electric expansion valve is MWhich of individual electric expansion valve, according to binary counting principle, can learn can be by MIndividual electric expansion valve is used respectively the several bit numbers of the minimum needs of binary representation, represents with s is individual.Example, if M is 2, s is 1, can be swollen as these 2 electronics with 1 bitThe flag of swollen valve, represents respectively this 2 electric expansion valves with " 0 ", " 1 ". Example again, if M is 3, s is 2, can be with 2 bits as these 3 electronic expansionsThe flag of valve.
The target opening value of the first electric expansion valve is for obtaining in step 201, due to firstElectric expansion valve is any in M electric expansion valve, and therefore, target opening value is requiredThe bit number accounting for needs to write the maximum opening value of any electric expansion valve. Example, ifIn indoor set, have 2 electric expansion valves, the maximum opening value of one of them is 2000Pluse,Another maximum opening value is 1800Pluse, and in these 2 electric expansion valves, maximum is opened soDegree value is 2000Pluse, now minimum needs 11 bits, i.e. t=11; Example again,If there are 3 electric expansion valves in indoor set, this maximum opening value of 3 is respectively2000Pluse, 2000Pluse, 1800Pluse, in these 3 electric expansion valves, maximum is opened soDegree value is 2000Pluse, now minimum needs 11 bits, i.e. t=11.
Separately, those skilled in the art can draw according to the implication of above-mentioned N, s, t, and s+t is littleIn equaling 8N.
In embodiments of the present invention, the electric expansion valve of the M in indoor apparatus of air conditioner has mark,And this mark is correspondingly also buffered in the buffer area that is stored in air-conditioner outdoor unit. A kind of situationThat the each of each electric expansion valve in buffer area in M electric expansion valve of buffer memory opensDegree value is all to there being mark; A kind of situation is, M electric expansion valve of buffer memory in buffer areaIn the corresponding mark of each electric expansion valve, and this mark and electric expansion valve twoIndividual opening value is corresponding respectively. In the embodiment of the present invention, to each electricity in M electric expansion valveThe mark of sub-expansion valve and the corresponding relation of electric expansion valve do not do concrete restriction.
Further, the mark of the each electric expansion valve in M electric expansion valve differsSample.
When air-conditioner outdoor unit obtains after the target opening value of the first electric expansion valve, air-conditioner outdoor unitSimultaneously by the mark of the first electric expansion valve getting. Correspondingly, by the first electric expansion valveTarget opening value while being converted into the target opening value that accounts for a continuous t bit, by swollen the first electronicsThe mark of swollen valve is also converted into the mark that accounts for s bit, then will account for of a continuous s bitThe mark of one electric expansion valve and account for the target aperture of the first electric expansion valve of a continuous t bitValue generates aperture control information.
In above-described embodiment, air-conditioner outdoor unit can first turn the mark of this first electric expansion valveFor accounting for the mark of s bit, then the target opening value of the first electric expansion valve is converted into the company of accounting forThe target opening value of continuous t bit; Can be first by the target opening value of this first electric expansion valveBe converted into the target opening value that accounts for a continuous t bit, then the mark of the first electric expansion valve is turnedFor accounting for the mark of s bit; Can also the mark of the first electric expansion valve be transferred to and account for s simultaneouslyThe mark of individual bit, is converted into the target opening value of the first electric expansion valve to account for continuous t ratioSpecial target opening value. In the embodiment of the present invention, to air-conditioner outdoor unit by the first electric expansion valveMark or the target opening value sequencing that transfers bit value to do not do concrete restriction.
Equal at 2 o'clock as example taking M below, introduce air-conditioner outdoor unit and can control indoor apparatus of air conditionerIn the opening value of 2 electric expansion valves.
Particularly, table one is for taking the aperture control information form of 2 bytes, due to M etc.In 2, can be with 2 bits the flag as 2 electric expansion valves, and 2 wordsJoint comprises 16 bits altogether, so, can utilize remaining 15 bits to representThe target opening value of the first electric expansion valve. And in actual applications, the maximum of electric expansion valveAperture is generally 2000Pluse, and 2000Pluse can occupy at most 11 bits, uses11 bits just can transmit the precision of 2000Pluse. In Table 1, can select flagRepresent flag, represent the target opening value of the first electric expansion valve with 11 bits, surplus4 remaining bits can be vacant. Such as, in the time that flag is 0, with bit0～bit10 statementThe opening value of first electric expansion valve, the mark of the first electric expansion valve is converted into and accounts for 1Bit be designated 0; In the time that flag is 1, bit0～bit10 explains second electric expansion valveOpening value, the mark of the second electric expansion valve be converted into account for 1 bit be designated 1.
Table one occupies the host-host protocol of 2 bytes
| flag | Bit14 | Bit13 | Bit12 | Bit11 | Bit10 | Bit9 | Bit8 |
| Bit7 | Bit6 | Bit5 | Bit4 | Bit3 | Bit2 | Bit1 | Bit0 |
In above-mentioned steps 202, after generating aperture control information, also comprise, by this apertureControl information is sent to buffer area. Owing to carrying the first electric expansion valve in aperture control informationMark and target opening value, so, can be by the mark of the first electric expansion valve and buffer areaThe mark of electric expansion valve compare, thereby determine delay corresponding with the first electric expansion valveDeposit the electric expansion valve in district, the opening value of the electric expansion valve in buffer area is upgraded.
A kind of example, buffer area is cached with two opening values of two electric expansion valves, is respectivelyThe first opening value of first electric expansion valve and the second opening value, second electric expansion valveThe first opening value and the second opening value. Wherein, the time of the first opening value buffer memory and current timeDifference be less than the difference of the second opening value cache-time and current time.
