The specific embodiment
Control method in the embodiment of the present invention can be applied to refrigeration system, can have M valve in described refrigeration system, wherein M can be positive integer, and described method can comprise: need to determine N valve of work from a described M valve, N is not less than 1 and be not more than the integer of M; Judge that whether N is greater than the first present count value; If whether N greater than described the first present count value, judges the first-phase numerical value that needs excitation in a described N valve greater than the second present count value, described first-phase numerical value is the total phase numerical value that needs excitation in a described N valve; If greater than described the second present count value, controlling a described N valve, described first-phase numerical value begins action according to the first preset rules.
In the embodiment of the present invention, whether can at first judge needs the valve of work quantity N greater than described the first present count value, if N is greater than described the first present count value, can continue to judge that whether the described first-phase numerical value that needs excitation in a described N valve is greater than described the second present count value, if greater than described the second present count value, can controlling a described N valve, described first-phase numerical value begins action according to described the first preset rules.Adopt the control method in the embodiment of the present invention, can need at the valve that needs work the valve of work to begin action according to described the first preset rules than multi-time control system, all valves are started working simultaneously, energy savings comparatively, and, move according to described the first preset rules, be equivalent to make each valve to move in turn, and the time of each valve intermediate suspension action is very short, neither can have influence on the service behaviour of valve, also can be issued to energy-conservation effect in the prerequisite that guarantees each valve normal operation simultaneously.
Referring to Fig. 1, the control method in the embodiment of the present invention can be applied to refrigeration system, can include M valve in described refrigeration system, and M can be positive integer, and the main flow process of described method is as follows:
Step 101: need to determine N valve of work from a described M valve, N is not less than 1 and be not more than the integer of M.
In the embodiment of the present invention, described refrigeration system can be air-conditioning system, can be also perhaps other refrigeration systems.
Can have M valve in described refrigeration system, at first can need determine N valve of work from a described M valve.Better, in the embodiment of the present invention, described valve can refer to electric expansion valve, perhaps described valve also can refer to the valve of other types.
Step 102: judge that whether N is greater than the first present count value.
Need to determine work N valve arranged after, can judge that whether N is greater than described the first present count value.Described the first present count value can pre-set according to actual conditions.
Step 103: if whether N greater than described the first present count value, judges the first-phase numerical value that needs excitation in a described N valve greater than the second present count value, described first-phase numerical value is the total phase numerical value that needs excitation in a described N valve.
If judgement determines that N is not more than described the first present count value, can control a described N valve and normally begin action.
If judgement determines that N greater than described the first present count value, can continue to judge that whether the described first-phase numerical value that needs excitation in a described N valve is greater than described the second present count value.Described the second present count value can pre-set according to actual conditions.
Wherein, continue to judge that the described first-phase numerical value that needs excitation in a described N valve whether greater than described the second present count value, can be divided into two kinds of situations:
One, because described valve can pass through step motor control, therefore can be when i clap, when clapping at described i, judgement need the described first-phase numerical value of excitation whether greater than described the second present count value in a described N valve.For example, i can be for being not less than 0 integer, and for example, i=1 namely, when first count begins, can judge first that whether the described first-phase numerical value that needs excitation when described first count in a described N valve is greater than described the second present count value.Perhaps for example, whether i=2 namely, after second count begins, can judge the described first-phase numerical value that needs excitation when described second count in a described N valve greater than described the second present count value, etc., by that analogy.
Two, can be when i cycle, whether judgement needs the described first-phase numerical value of excitation greater than described the second present count value when described i the cycle in a described N valve.Wherein, because described valve can pass through step motor control, so one-period can include the j bat.For example, i can be for being not less than 0 integer.
Concrete, M=3 for example, wherein the one-period of first valve comprises that altogether 6 clap, wherein the one-period of second valve includes 8 bats altogether, wherein the one-period of the 3rd valve includes 10 bats altogether, when carrying out this judgement, can think that one-period includes 6 and claps, namely, when 6 initial bat, three valves may move together, clap since the 7th, described second valve and described the 3rd valve still are operated in first cycle, and described first valve begins operating in second period.Therefore, can be take 6 bats as one-period when judgement, can at first be informed in before judgement in this 6 bat needs the quantity of the number of phases of excitation in every bat, more therefrom determines maximum.
For example, determine when described i the cycle, the quantity that needs the number of phases of excitation during first count is 3, the quantity that needs the number of phases of excitation when second count is 5, the quantity that needs the number of phases of excitation when third shot is 7, needing the quantity of the number of phases of excitation when the 4th claps is 9, needing the quantity of the number of phases of excitation when the 5th claps is 8, needing the quantity of the number of phases of excitation when the 6th claps is 4, need can to determine the quantitative value of the number of phases of excitation maximum when the 4th claps, when judgement, whether can judge 9 greater than described the second present count value.
Step 104: begin action according to the first preset rules if described first-phase numerical value greater than described the second present count value, is controlled a described N valve.
If judgement determines that described first-phase numerical value is not more than described the second present count value, can control described N valve regular event.
If judgement is determined described first-phase numerical value greater than described the second present count value, can control a described N valve and begin action according to described the first preset rules.
One, optional, if step 103 is to clap at i, when judgement is clapped at described i, whether described first-phase numerical value is greater than described the second present count value, and this step can be:
If judgement determines that described first-phase numerical value is greater than described the second present count value when described i claps, P valve can controlling in a described N valve begins action, wherein, a described P valve needs the second-phase numerical value of excitation to be not more than described the second present count value.And can control simultaneously remaining N-P valve and suspend action.Wherein, P is not less than 1 and be not more than the integer of N, and described second-phase numerical value is the total phase numerical value that needs excitation in a described P valve.
After described P valve working Q claps, control described P valve and suspend action, and judge that N-P valve needs the third phase numerical value of excitation whether greater than described the second present count value; Q is positive integer, and described third phase numerical value is the total phase numerical value that needs excitation in a described N-P valve.
When described third phase numerical value during greater than described the second present count value, L the valve of controlling in a described N-P valve begins action, and other valves of controlling except a described L valve suspend action, wherein, a described L valve needs the second-phase numerical value of excitation to be not more than described the second present count value, and L is not less than 1 and be not more than the integer of N-P.
When described third phase numerical value is not more than described the second present count value, control a described N-P valve and begin action, and other valves of controlling except a described N-P valve suspends action.
For example, describe as an example of N=2, i=1 example.As shown in Figure 2, suppose that first valve and second valve are the valve of four phase eight beat, these two valves are all clapped as one-period with eight.Fig. 2 is the work schematic diagram in one-period of these two valves.Zone circle character representation umber of beats in Fig. 2,1 in Fig. 2 represents first valve, second valve of 2 expressions, the A in Fig. 2, B, C, D represent four phases of first valve, E, F, G, H represent four phases of second valve.
As can be seen from Figure 2, when first count, it is 2 that two valves need the phase numerical value of excitation, when second count, it is 4 that two valves need the phase numerical value of excitation, and when third shot, it is 2 that two valves need the phase numerical value of excitation, when the 4th claps, it is 4 that two valves need the phase numerical value of excitation, and when the 5th clapped, it was 2 that two valves need the phase numerical value of excitation, when the 6th claps, it is 4 that two valves need the phase numerical value of excitation, and when the 7th clapped, it was 2 that two valves need the phase numerical value of excitation, when the 8th clapped, it was 4 that two valves need the phase numerical value of excitation.
For example, when first count began, in the time of can at first judging described first count, whether two valves needed the described first-phase numerical value of excitation greater than described the second present count value.In the present embodiment, can suppose that described the second present count value is 2.When first count, described first-phase numerical value is 2, and namely described first-phase numerical value is not more than described the second present count value, can control these two valves equal regular event when first count.
When second count begins, can judge that two valves need the described first-phase numerical value of excitation whether greater than described the second present count value when described second count.When described second count, described first-phase numerical value is 4, obvious described first-phase numerical value is greater than described the second present count value, a valve can controlling in these two valves moves, and this valve that moves needs the phase numerical value of excitation should be not more than described the second present count value when second count.Therefore in the present embodiment, these two valves need the phase numerical value of excitation to be 2 when second count, can control first wherein that first valve moves when second count, can control second remaining valve simultaneously and suspend action when second count.
When first valve when second count work is complete, can continue to judge that remaining valve needs the phase numerical value of excitation whether greater than described the second present count value, because of only remaining second valve in the present embodiment, this second valve needs the phase numerical value of excitation to be not more than described the second present count value, therefore can control described second valve and begin action, after described second valve event one clapped, third shot begins, and can continue to judge that these two valves need the described first-phase numerical value of excitation whether greater than described the second present count value when described third shot.That is, in the present embodiment, one bat that has been equivalent to first valve interval, and the time of clapping is very short, can ignore for a valve, can not have influence on the performance of valve.Simultaneously, control again valve and moved in turn, can effectively save the energy.
Deterministic process the like, repeat no more herein, specifically can referring to Fig. 3, control the work schematic diagram of latter two valve for the control method in the present invention.Fig. 3 is the work schematic diagram in one-period of these two valves after controlling by the control method in the embodiment of the present invention.Zone circle character representation umber of beats in Fig. 3,1 in Fig. 3 represents first valve, second valve of 2 expressions, the A in Fig. 3, B, C, D represent four phases of first valve, E, F, G, H represent four phases of second valve.Wherein, represent that with thick line valve suspends action in Fig. 3.Only show the control result of part umber of beats in Fig. 3, therefore other can all not illustrate by that analogy, represents to omit with hyperbola.
Need to prove, after controlling, a valve is completed the work of one-period, because of the centre, may be arranged the moment of suspending action, and is long possibly when the time length ratio that therefore needs is controlled.
And, be all to judge when every bat in the present embodiment, also can judge after several bats in work, be not limited to every bat, namely the time of certain or a plurality of valve intermediate suspensions can be also several bats, only otherwise the service behaviour that affects valve gets final product.
Two, optional, if step 103 is i cycle, whether described first-phase numerical value is greater than described the second present count value when i cycle in judgement, and this step can be:
If described first-phase numerical value is greater than described the second present count value when described i the cycle, P the valve of controlling in a described N valve begins action, wherein, a described P valve needs the second-phase numerical value of excitation to be not more than described the second present count value, and controls remaining N-P valve and suspend action; P is not less than 1 and be not more than the integer of N, and described second-phase numerical value is the total phase numerical value that needs excitation in a described P valve.
At described P valve working H all after date, control described P valve and suspend action, and judge that N-P valve needs the third phase numerical value of excitation whether greater than described the second present count value; H is positive integer, and described third phase numerical value is the total phase numerical value that needs excitation in a described N-P valve.
When described third phase numerical value during greater than described the second present count value, L the valve of controlling in a described N-P valve begins action, and other valves of controlling except a described L valve suspend action, wherein, a described L valve needs the 4th phase numerical value of excitation to be not more than described the second present count value, L is not less than 1 and be not more than the integer of N-P, and described the 4th phase numerical value is the total phase numerical value that needs excitation in a described L valve.
When described third phase numerical value is not more than described the second present count value, control a described N-P valve and begin action, and other valves of controlling except a described N-P valve suspends action.
For example, describe as an example of N=2, i=1 example.
For example, in first cycle, during first count, it is 2 that two valves need the phase numerical value of excitation, and when second count, it is 4 that two valves need the phase numerical value of excitation, when third shot, it is 2 that two valves need the phase numerical value of excitation, and when the 4th clapped, it was 4 that two valves need the phase numerical value of excitation, when the 5th claps, it is 2 that two valves need the phase numerical value of excitation, and when the 6th clapped, it was 4 that two valves need the phase numerical value of excitation, when the 7th claps, it is 2 that two valves need the phase numerical value of excitation, and when the 8th clapped, it was 4 that two valves need the phase numerical value of excitation.Namely to need the maximal phase numerical value of excitation in first cycle be 4 to two valves.
For example, when first cycle begins, whether can at first judge 4 greater than described the second present count value.In the present embodiment, can suppose that described the second present count value is 2.Judgement determines that these two valves need the maximal phase numerical value of excitation greater than described the second present count value when first cycle.。
A valve can controlling in these two valves is done advanced action of first cycle, and this valve that moves needs the phase numerical value of excitation should be not more than described the second present count value when first cycle.In the present embodiment, these two valves need the maximal phase numerical value of excitation to be 2 when first cycle, therefore can control first wherein that first valve moves when first cycle, can control second remaining valve simultaneously and suspend action when first cycle.
When first valve when first cycling is complete, can judge that remaining valve needs the maximal phase numerical value of excitation whether greater than described the second present count value, because of only remaining second valve in the present embodiment, this second valve needs the maximal phase numerical value of excitation to be not more than described the second present count value, therefore can control described second valve and begin action, after described second valve event one-period, can continue to judge that these two valves need the described first-phase numerical value of excitation whether greater than described the second present count value when second period.That is, in the present embodiment, the one-period that has been equivalent to first valve interval, and the time of one-period is very short, can ignore for a valve, can not have influence on the performance of valve.Simultaneously, control again valve and moved in turn, can effectively save the energy.
Deterministic process the like, repeat no more herein, specifically can referring to Fig. 3, control the work schematic diagram of latter two valve for the control method in the present invention.
And, be all to judge when each cycle in the present embodiment, also can judge after several cycles of work, be not limited to each cycle, the time that is certain or a plurality of valve intermediate suspensions can be also several cycles, only otherwise the service behaviour that affects valve gets final product.
Referring to Fig. 4, the invention provides a kind of control device, described control device can be applied to refrigeration system, can have M valve in described refrigeration system, and M is positive integer.Described control device can comprise determination module 401, the first judge module 402, the second judge module 403 and control module 404.
The first judge module 402 can be used for judging that whether N is greater than the first present count value.
The first judge module 402 specifically can be used for clapping at i, and when judgement is clapped at described i, whether described first-phase numerical value is greater than described the second present count value, and i is not less than 0 integer.
