For fully understanding the object of the invention, characteristic and effect, now through following concrete embodiment, and cooperate appended graphicly, the present invention is done a detailed description, explain as after:
At first seeing also Fig. 1, is the control circuit calcspar of the present invention in an embodiment.Relay 110 is driven the conducting (112 pairs of relays 110 of driver are excitatory) and disconnection (112 pairs of relay 110 demagnetizations of driver) of relay 110 by driver 112.Input detects unit 120 and output detects power input and each other current potential sequential situation of power output end that 122 of unit detect out relay 110 respectively, and connected control unit 101 is given in the time series data transmission that is obtained.This control unit is in order to the time parameter adquisitiones of the corrected AC current potential switching sequence of execution the present invention proposition; And with in being stored in the time series data of obtaining; During for follow-up relay offered load 130; Can make the conducting of relay and the sequential point of disconnection all be positioned at the electronegative potential place through these time series datas by control unit, for example: the electronegative potential place of zero potential, and then avoid the generation of spark.
Then seeing also Fig. 2, is the sequential sketch map of the ON time parameter obtaining method of corrected AC current potential switching sequence in one embodiment of the invention, and transverse axis is a time T, and the longitudinal axis is potential value V.Wherein, The input source that the present invention preferably will exchange the string ripple converts the square wave of halfwave rectifier into, and this square wave is the oscillogram shown in the S in graphic then, and the method for the conversion unit that detects capable of using is reached; For example: utilize the pressure drop of big resistance to make high pressure change low pressure with the serial connection mode; Make AC sine wave transfer the square wave of halfwave rectifier to by transistorized high electronegative potential trigger theory again, this belongs to known electronic technology, repeats no more in this.Wherein, the square wave of halfwave rectifier is also for example capable of using among Fig. 2: the logic reversal device, and the square wave of halfwave rectifier is converted into when interchange string ripple is positioned at high potential, the square wave after the conversion is positioned at the zero potential state.
As shown in Figure 2, after alternating current converted the square wave of halfwave rectifier into, its half wave cycles time was Thac, and this square wave promptly has the paramount interdigit of low level or high-order to the zero potential crossover point between low level.The present invention promptly utilizes the zero potential crossover point of these crossover points and relay output end to carry out the judgement of various states.Moreover; Because the label of relay or material difference promptly have different reaction time performances; Be relay by excitatory back to time of real conducting or relay by demagnetization after to the real time of breaking off; Therefore, in excitatory part the possible state of three kinds of correspondences is arranged, that is: the R1-relay conducting reaction time is less than half wave cycles time T hac; The R2-relay conducting reaction time is greater than half wave cycles time T hac; The R3-relay conducting reaction time equals half wave cycles time T hac; In the demagnetization part also together.
The step of time parameter adquisitiones of the present invention is following:
A, obtain the half wave cycles time value of input source in the input side of this relay;
B, when the half wave cycles time value of the phase bit timing of this relay input side is positioned at the zero potential crossover point between high electronegative potential conversion, with the half wave cycles time value of this moment as the first sequential point and switch the state of this relay;
C, when the half wave cycles time value of the phase bit timing of this relay outlet side is positioned at the zero potential crossover point between high electronegative potential conversion, with the half wave cycles time value of this moment as the second sequential point and switch the state of this relay; And
D, when the half wave cycles time value of the phase bit timing of this relay outlet side is positioned at the zero potential crossover point between high electronegative potential conversion, with the half wave cycles time value of this moment as the 3rd sequential point and switch the state of this relay,
Wherein, the reaction time parameter of this relay can be obtained, and the make-up time parameter of this relay can be obtained according to this second sequential point and the 3rd sequential point according to this first sequential point and this second sequential point.
Graphic the illustrating in greater detail as follows of arranging in pairs or groups:
As shown in Figure 2, at first to the R1 part, the operation steps of control unit 101 is following:
A1, obtain the half wave cycles time value Thac of input source after; Utilize input shown in Figure 1 to detect the phase bit timing that unit 120 detects the input of relay 110; That is, detect the phase bit timing of this square wave S, (preface point a in real time when its phase bit timing is positioned at electronegative potential and is converted to the zero potential crossover point between high potential; Control unit 101 can write down each specific sequential point time value and use for follow-up estimation), enable relay.
A2, utilize output shown in Figure 1 to detect the phase bit timing that unit 122 detects the output of relay 110.(preface point b in real time) through the time difference of sequential point a and sequential point b, obtains the first conducting reaction time value TR1 of relay when the square wave S of relay outlet side 1 phase bit timing is positioned at electronegative potential and is converted to high potential.
A3, utilize output shown in Figure 1 to detect the phase bit timing that unit 122 detects the output of relay 110.(preface point c in real time) through the phase bit timing point b of this relay outlet side and the time difference of sequential point c, obtains the first conducting make-up time value TC1 of this relay when the square wave S1 of relay outlet side phase bit timing is positioned at high potential and is converted to electronegative potential.
The relation of A4, the first conducting make-up time of judgement value TR1 and this half wave cycles time value Thac; When this first conducting make-up time, value TR1 was less than this half wave cycles time value Thac, the time parameter of decision turn-on relay was this first conducting reaction time value TR1 and this first conducting make-up time value TC1.
Therefore, control unit has promptly been obtained the time parameter of excitatory turn-on relay and has been recorded in wherein, afterwards when this relay is by excitatory conducting each time; Because it is the odd number times (is 1 times at this) of half wave cycles time value Thac that the first conducting reaction time value TR1 adds this first conducting make-up time value TC1; Therefore, control unit 101 can be when the phase bit timing of relay input side be positioned at the zero potential crossover point, in advance through this first conducting make-up time value TC1; Control Driver 112 excitatory these relays 110 again; So, the last firing point of this relay promptly can the position at the electronegative potential place, and then avoid the generation of spark.
As shown in Figure 2, owing to R2, R3 can't be by judicious reaction time and make-up times (can know in graphic that the reaction time of recognizing measured reaction time and reality is different) in abovementioned steps.Therefore; To relay R 2; In the step of the relation of the first conducting make-up time of judgement value TC1 that aforementioned A4 is ordered and this half wave cycles time value Thac, more comprise: non-during less than this half wave cycles time value Thac in this first conducting make-up time value TC1 (being TC2 in Fig. 2), the operation steps of control unit 101 is following:
B1, when any one phase bit timing of relay R 2 input sides or outlet side is positioned at high potential and is converted to the zero potential crossover point between electronegative potential (preface point d in real time), make relay R 2 anergies.
B2, when the phase bit timing of relay R 2 input sides is positioned at high potential and is converted to the zero potential crossover point between electronegative potential (preface point e in real time), enable relay R 2.
B3, when the phase bit timing of relay R 2 outlet sides is positioned at electronegative potential and is converted to high potential (preface point f in real time), sequential time point e through enabling relay R 2 and the time difference of sequential point f are obtained the second conducting reaction time value TR2 of relay R 2.
B4, when the phase bit timing of relay R 2 outlet sides is positioned at high potential and is converted to electronegative potential (preface point g in real time); Phase bit timing through relay R 2 outlet sides is converted to the sequential time point f of high potential and the time difference of sequential point g by electronegative potential, obtains the second conducting make-up time value TC2 of relay R 2.
The relation of B5, the second conducting make-up time of judgement value TC2 and half wave cycles time value Thac; When this second conducting make-up time, value TC2 was less than this half wave cycles time value Thac, the time parameter of decision turn-on relay R2 was this second conducting reaction time value TR2 and this second conducting make-up time value TC2.
Likewise, control unit has promptly been obtained the time parameter of relay R 2 and has been recorded in wherein, afterwards when this relay is by excitatory conducting each time; Because the second conducting reaction time value TR2 adds that the second conducting make-up time value TC2 is the even-multiple (is 2 times at this) of half wave cycles time value Thac; Therefore, control unit 101 can be when the phase bit timing of relay input side be positioned at the zero potential crossover point, in advance through this second conducting make-up time value TC2; It is excitatory that Control Driver 112 makes this relay 110 again; So, the last firing point of this relay promptly can the position at the electronegative potential place, and then avoid the generation of spark.
As shown in Figure 2; Situation as for relay R 3 roughly is same as relay R 2; Difference be in; Be equal in the step of relation of the 3rd conducting make-up time of judgement value TC3 and half wave cycles time value Thac of aforementioned B5 step and more comprise: when the 3rd conducting make-up time value TC3 equaled this half wave cycles time value Thac, the time parameter of decision turn-on relay R3 be the 3rd conducting reaction time value TR3, and the 3rd conducting make-up time value TC3 is zero.This is reaction time because of relay R 3 to be equivalent to half wave cycles time value Thac; Therefore the control that need not to compensate; Control unit 101 only needs the excitatory starting point of control relay R3 when the phase bit timing of relay input side is positioned at the zero potential crossover point, to get final product, the real excitatory firing point of relay R 3 promptly can the position at the electronegative potential place.Wherein, aforesaid the 3rd conducting reaction time value TR3 and the 3rd conducting make-up time value TC3 be for ease of graphic explanation, is worth with the second conducting reaction time value and this second conducting make-up time in claims of Yu Houshu and represents.
Aforementioned is the time parameter adquisitiones of the excitatory conducting of relay; Generally speaking, during excitatory conducting if be positioned at the high potential point, the generation of its spark than demagnetization break off when the high potential point seriously; Therefore, in a preferred embodiment, can more comprise the time parameter adquisitiones that demagnetization is broken off.
Yet, likewise, in demagnetization disconnection process, the possible state of three kinds of correspondences also being arranged, that is: the r1-relay breaks off the reaction time less than half wave cycles time T hac; The r2-relay breaks off the reaction time greater than half wave cycles time T hac; The r3-relay disconnection reaction time equals half wave cycles time T hac.
See also Fig. 3; Be corrected AC current potential switching sequence in one embodiment of the invention opening time parameter obtaining method the sequential sketch map; About the basis for estimation principle of breaking off: the square wave current potential at detecting relay input side and outlet side two ends, must being the correctness that different potentials is judged the relay disconnection at that time breaking off.
As shown in Figure 3, at first to the r1 part, the operation steps of control unit 101 is following:
A1, under the relay conducting, (preface point a) makes the relay anergy in real time when any one phase bit timing of relay input side or outlet side is positioned at electronegative potential and is converted to the zero potential crossover point between high potential.
A2, when the phase bit timing of relay outlet side is positioned at high potential and is converted to electronegative potential (preface point b in real time), sequential point a through making the relay anergy and the time difference of sequential point b are obtained the first disconnection reaction time value Tr1 of relay.Wherein, in do not obtain sequential point b before, also can judge earlier that whether (or can in the a2 step, judge) breaks off reaction time less than 3 Thac values, if then represent this relay to have the defective on the body usually more than or equal to 3 Thac values, should eliminate; Otherwise if less than 3 Thac values, the r2 relay step of stating after then entering is calculated with the reference compensation of carrying out another phase place.
A3, confirm through the high potential phase bit timing of this relay input side whether this relay breaks off; For instance; When if the relay input side is positioned at high potential once more after the a2 step; The relay outlet side is not promoted to high potential simultaneously, and on behalf of this relay, this promptly correctly broken off, breaks off the reaction time this moment to be less than or equal to 2 Thac values; Otherwise when after the a2 step, being positioned at high potential as if the relay input side once more, the relay outlet side also is promoted to high potential simultaneously, and on behalf of this relay, this promptly correctly broken off yet, represents it to break off reaction time greater than 2 Thac values.Sequential is proceeded; Then; A kind of situation is: when the relay input side is reduced to electronegative potential by high potential once more; The relay outlet side is reduced to disconnection reaction time that electronegative potential just represents this relay more than or equal to 3 Thac values, represents this relay to have the defective on the body, should eliminate; Another situation is: before the relay input side was reduced to electronegative potential by high potential once more, the relay outlet side promptly was reduced to electronegative potential ahead of time, and this disconnection reaction time of promptly representing this relay is less than 3 Thac values.
A4, when the phase bit timing of relay input side is positioned at high potential and is converted to electronegative potential (preface point c in real time); Phase bit timing through the relay outlet side is converted to the sequential point b of electronegative potential and the time difference of sequential point c by high potential, obtains first of relay and breaks off make-up time value Tc1.
A5, judge this first break off make-up time value Tc1 and this half wave cycles time value Thac relation; When this first disconnection make-up time was worth Tc1 less than this half wave cycles time value Thac, the time parameter that this relay is broken off in decision was this first disconnection reaction time value Tr1 and this first disconnection make-up time value Tc1.
Therefore, control unit 101 has promptly been obtained demagnetization and has been broken off the time parameter of relay and be recorded in wherein, afterwards when this relay broken off by demagnetization each time; Add that this first disconnection make-up time value Tc1 is the odd number times (is 1 times at this) of half wave cycles time value Thac because first breaks off reaction time value Tr1; Therefore, control unit 101 can be when the phase bit timing of relay input side be positioned at the zero potential crossover point, in advance through this first disconnection make-up time value Tc1; Control Driver 112 makes this relay 110 demagnetizations again; So, the last cut-off point of this relay promptly can the position at the electronegative potential place, and then avoid the generation of spark.
As shown in Figure 3; Because r2, r3 can't (can be known in graphic that the reaction time of recognizing measured reaction time and reality is different by judicious reaction time and make-up time in abovementioned steps; This be because of relay when breaking off; Whether its outlet side current potential is identical with the input side current potential, is all electronegative potential, break off so can't judge relay).Therefore; To relay r2;, judgement that aforementioned a5 is ordered first more comprises in breaking off the step of relation of make-up time value Tc1 and half wave cycles time value Thac: non-during less than this half wave cycles time value Thac in this first disconnection make-up time value Tc1 (being Tc2 in Fig. 3); The operation steps of control unit 101 as after state step; Wherein, described " make-up time value Tc1 is non-less than this half wave cycles time value Thac in this first disconnection " can be represented in the aforementioned a2 step, judges that relay breaks off the situation of reaction time more than or equal to 3 Thac values.
B1, when the phase bit timing of relay input side is positioned at high potential and is converted to the zero potential crossover point between electronegative potential (preface point d in real time), enable relay.
B2, when the phase bit timing of relay outlet side is positioned at high potential and is converted to electronegative potential (preface point e in real time), (real-time preface point e) made the relay anergy when perhaps the phase bit timing of this relay input side was positioned at the zero potential crossover point once more after relay is enabled.
B3, when the phase bit timing of relay outlet side is positioned at high potential and is converted to electronegative potential (preface point g in real time); Sequential point e through making this relay anergy and the time difference of sequential point g; Obtain second of relay and break off reaction time value Tr2; Simultaneously can judge whether this relay breaks off, if certain disconnection then gets into the b4 step through the phase bit timing (preface point f in real time) that this relay input side is positioned at high potential; Otherwise, get back to the b3 step.
B4, when the phase bit timing of relay input side is positioned at high potential and is converted to electronegative potential (preface point h in real time); Phase bit timing through this relay outlet side is converted to the sequential point g of electronegative potential and the time difference of sequential point h by high potential, obtains second of relay and breaks off make-up time value Tc2.
The relation that make-up time value Tc2 and this half wave cycles time value Thac are broken off in b5, judgement second; When this second conducting make-up time, value Tc2 was less than this half wave cycles time value Thac, the time parameter that this relay is broken off in decision was this second disconnection reaction time value Tr2 and this second disconnection make-up time value Tc2.
Therefore, control unit 101 has promptly been obtained the time parameter of relay r2 and has been recorded in wherein, afterwards when this relay is broken off by demagnetization each time; Add that this second disconnection make-up time value Tc2 is the even-multiple (is 2 times at this) of half wave cycles time value Thac because second breaks off reaction time value Tr2; Therefore, control unit 101 can be when the phase bit timing of relay input side be positioned at the zero potential crossover point, in advance through this second disconnection make-up time value Tc2; Control Driver 112 makes this relay 110 demagnetizations again; So, the last cut-off point of this relay promptly can the position at the electronegative potential place, and then avoid the generation of spark.
Then; As shown in Figure 3; To relay r3,, judgement that aforementioned a5 is ordered first more comprises in breaking off the step of relation of make-up time value Tc1 and half wave cycles time value Thac: non-during in this first disconnection make-up time value Tc1 less than this half wave cycles time value Thac, with Fig. 3; That is non-during in the disconnection make-up time value Tc3 that obtains for the 1st time less than half wave cycles time value Thac, the operation steps of control unit 101 is following:
C1, when the phase bit timing of relay input side is positioned at high potential and is converted to the zero potential crossover point between electronegative potential (preface point d in real time), enable relay.
C2, when the phase bit timing of relay outlet side is positioned at high potential and is converted to electronegative potential (preface point e in real time), (real-time preface point e) made the relay anergy when perhaps the phase bit timing of this relay input side was positioned at the zero potential crossover point once more after relay is enabled.
The phase bit timing that c3, the phase bit timing of treating the relay input side are positioned at high potential and this relay outlet side once more is not positioned at the sequential time point (preface point f in real time) of high potential; Phase bit timing through the relay outlet side is converted to the sequential point e of electronegative potential and the time difference of sequential point f by high potential, obtains the 3rd and breaks off reaction time value Tr3.
C4, when the phase bit timing of relay input side is positioned at the zero potential crossover point (in real time preface point h); Phase bit timing through aforementioned relay input side is positioned at the sequential point f of high potential and the time difference of sequential point h once more, obtains the 3rd of this relay and breaks off make-up time value Tc3.
C5, judge that the 3rd breaks off the relation of make-up time value Tc3 and this half wave cycles time value Thac; Equal this half wave cycles time value Thac or during in the 3rd conducting make-up time value Tc3 for this half wave cycles time value double; The time parameter that this relay is broken off in decision is the 3rd conducting reaction time value Tr3, and the 3rd disconnection make-up time value Tc3 is zero.
Therefore; Control unit 101 has promptly been obtained the time parameter of relay r3 and has been recorded in wherein; When this relay is broken off by demagnetization each time, only need consider the 3rd conducting reaction time value Tr3 afterwards, this is reaction time because of relay r3 to be equivalent to half wave cycles time value Thac; Therefore the control that need not to compensate; The demagnetization starting point that control unit 101 only needs control relay r3 is positioned in the phase bit timing of relay input side and gets final product when high potential is converted to the zero potential crossover point between electronegative potential, the real demagnetization cut-off point of relay r3 promptly can the position at the electronegative potential place, and then avoid the generation of spark.
In view of the above, the account form that obtains of parameter of the present invention is:
1, minimum integral multiple=TR of Thac (half wave cycles time value) (conducting reaction time value)+TC (conducting make-up time value);
2, minimum integral multiple=Tr of Thac (half wave cycles time value) (breaking off the reaction time value)+Tc (breaking off the make-up time value).
The present invention can be with being stored in a computer program in these methods and the computation rule; Make the online computer of product can accomplish the estimation of the reaction time parameter (conducting reaction time, disconnection reaction time) and the make-up time parameter (conducting make-up time value, disconnection make-up time are worth) of relay through the step that obtains of aforesaid computation rule and aforesaid relevant parameter in loading and after carrying out this computer program.
In sum; Parameter correlation time of relay can obtain via the automatic running of control unit; Make each relay can when making, be endowed precise time parameter controlling for control unit; And then avoid the generation of spark, and method of the present invention running fast, more can reduce manufacturing cost.
