The arbitrary and all combination of list of items.
Fig. 1 is refer to, an embodiment provides a kind of quick rolling-door control system, including frequency converter 100.Frequency converter
100 are able to electrically connect with encoder 200, electric system 300.Electric system 300 is used for driving door curtain (not shown)
It is up and descending.Electric system 300 is such as including motor, brake block, reductor.Door curtain can be by PVC (Polyvinyl
Chloride, polyvinyl chloride) weave cotton cloth or aluminium alloy extrusions composition.It is up, that is, open the door or rise.It is descending, that is, close the door or decline.
Encoder 200 is installed on electric system 300, for example, specifically can be installed on motor.Also, encoder 200
During door curtain upstream or downstream in measurement motor system 300 motor angular displacement, and exported and angular displacement to frequency converter 100
Corresponding electric signal.
Frequency converter 100 can cause door curtain upstream or downstream under encoder modes by controlled motor system 300.Tool
Body, frequency converter 100 can be using vector control mode, V/f controls or other motor control modes come the operation of controlled motor.
Also, it is up terminate soon, it is descending it is fast at the end of, frequency converter 100 all makes door curtain run slowly by controlled motor and reductor,
So that door curtain enters deceleration buffer state, to prevent from hitting track, folder people, and noise is reduced.
In the embodiment of the present invention, frequency converter 100 judges that door curtain is not arrived at the end of this is up according to above-said current signal
During up to upper limit position, the first deceleration time point for making door curtain reduce speed now operation during next time is up is adjusted, to cause door
Curtain reaches upper limit position at the end of next time is up.Also, frequency converter 100 judges that door curtain is descending at this according to above-said current signal
At the end of without lower position is reached when, regulation makes door curtain be reduced speed now the second deceleration time of operation during next time is descending
Point, to cause door curtain to reach lower position at the end of next time is descending.
Wherein, without reaching upper limit position at the end of up, equivalent at the end of up without completely in place.It is descending to terminate
When do not reach lower position, equivalent at the end of descending without completely in place.First deceleration time point, refers in up process
At the time of middle frequency converter 100 will make door curtain corresponding when reducing speed now up by controlled motor system 300.Second deceleration time
Point, when referring to corresponding when frequency converter during descending 100 will make door curtain reduce speed now descending by controlled motor system 300
Carve.Either up process, or descending process, change reduce speed now operation at the time of (be for example retarded or advanced deceleration when
Carve), then equivalent to changing the distance that door curtain in running is run altogether, so as to change door curtain it is out of service when it is residing
Position.
Therefore,, can be by appropriate if door curtain is no completely in place at the end of this is up by taking up process as an example
The first deceleration time point (for example postponing the first deceleration time point) during change is up, i.e., prolong during next time is up
The time that late door curtain reduces speed now, to cause door curtain to reach upper limit position in location at the end of next time is up,
So as to realize completely in place.Therefore, above-mentioned quick rolling-door control system provided in an embodiment of the present invention can be slowed down by changing
Time point adjust door curtain the location of at the end of upstream or downstream, so as to improve the degree of accuracy in place.
Specifically, in above-mentioned quick rolling-door control system, frequency converter 100 judges door curtain with specific reference to above-said current signal
When at the end of this is up without arrival upper limit position, more than upper limit position, door curtain is correspondingly arranged respectively in next up mistake
The first deceleration time point in journey is later than, prior to this first deceleration time point during up.
In other words, when frequency converter 100 judged according to electric signal door curtain at this it is up at the end of not completely in place when, then with
The first deceleration time point during this is up is compared, and has postponed first deceleration time of the door curtain during next time is up
Point, equivalent to the distance that door curtain is run altogether during next time is entirely up is extended, so that institute when door curtain is out of service
The position at place can reach upper limit position.When frequency converter 100 judged according to electric signal door curtain at this it is up at the end of exceed it is upper
During extreme position, then compared with the first deceleration time point during this is up, door curtain is advanced by during next time is up
First deceleration time point, equivalent to the distance that door curtain is run altogether during next time is entirely up is shortened, so that door curtain
It is upper limit position the location of when out of service.
In addition, under frequency converter 100 judges that door curtain is not reached at the end of this descending process with specific reference to above-said current signal
Extreme position, more than lower position when, be correspondingly arranged respectively door curtain next time it is descending during the second deceleration time point be later than, first
The second deceleration time point during this is descending.
In other words, when frequency converter 100 judged according to electric signal door curtain at this it is descending at the end of not completely in place when, then with
The second deceleration time point during this is descending is compared, and has postponed second deceleration time of the door curtain during next time is descending
Point, equivalent to the distance that door curtain is run during next time is entirely descending is extended, so that residing when door curtain is out of service
Position reach lower position.When frequency converter 100 judged according to electric signal door curtain at this it is descending at the end of exceed lower position
When, then compared with the second deceleration time point during this is descending, it is advanced by door curtain second subtracting during next time is descending
Fast time point, equivalent to the distance that door curtain is run during next time is entirely up is shortened, so that door curtain is out of service
When the location of be lower position.
Specifically, in above-mentioned quick rolling-door control system, electric signal is pulse signal.Also, frequency converter 100 can
Pulse signals are counted, so as to draw umber of pulse.It is understood that electric signal is not limited to a kind of shape of pulse signal
Formula, can also be other kinds of electric signal, such as electric signal can also directly be umber of pulse, i.e. encoder 200 except with
According to the function of the angular displacement output pulse signal of motor, the function that pulse signals are counted is also equipped with.
Further, for above-mentioned quick rolling-door control system, on the premise of electric signal is pulse signal, door curtain exists
The corresponding umber of pulse of upper limit position is reached at the end of up to reflect the high range pulse number (being designated as P) of door.Also, door curtain
It is 0 that the corresponding umber of pulse in lower position is reached at the end of descending.Wherein, range pulse number refers to become in the high learning process of door
What frequency device 100 learnt can reflect the high umber of pulse of quick rolling-door door.Therefore, when door curtain is at the end of up and in upper
During extreme position, the umber of pulse that frequency converter 100 is counted is then range pulse number.Afterwards, when door curtain is at the end of descending and under being in
During extreme position, the umber of pulse that frequency converter 100 is counted is 0.Therefore, during up, the statistical of umber of pulse is according to gradually passing
The mode of increasing is counted, and during descending, the statistical of umber of pulse is counted in the way of gradually successively decreasing.
In addition, frequency converter 100 judge this it is up at the end of umber of pulse (being designated as M) be less than, more than range pulse number when,
Correspond to respectively and assert that door curtain, without arrival upper limit position, more than upper limit position, afterwards, corresponds to increase respectively at the end of this is up
Greatly, the first umber of pulse for making door curtain reduce speed now operation during next time is up is reduced.
Wherein, the first umber of pulse of this up process is set as O.During this is up, frequency converter 100 is right at any time
The pulse signal that encoder 200 is exported is counted, when umber of pulse reaches corresponding first umber of pulse of this up process, change
Frequency device 100 then controls door curtain to reduce speed now operation.When door curtain stops up, if frequency converter 100 judges M<During P, then it represents that
Door curtain location at the end of this is up is not up to upper limit position, then frequency converter 100 then increases the first umber of pulse, example
The first umber of pulse is such as updated to P-M+O, so as to delay the time that door curtain reduces speed now during next time is up.If become
Frequency device 100 judges M>P, then it represents that door curtain location at the end of this is up has exceeded upper limit position, then frequency converter
100 the first umber of pulses of reduction, for example, be updated to O- (M-P), so as to be advanced by door curtain in next up mistake by the first umber of pulse
The time reduced speed now in journey.
In addition, frequency converter 100 judge this it is descending at the end of umber of pulse (being designated as N) be less than, more than 0 when, correspond to respectively
Assert that door curtain exceedes lower position, without lower position is reached at the end of this is descending, afterwards, increase is corresponded to respectively, is reduced
Door curtain is reduced speed now during next time is descending and run corresponding second umber of pulse.
Wherein, the second umber of pulse of this descending process is designated as C.During this is descending, frequency converter 100 is right at any time
The pulse signal that encoder 200 is exported is counted, when umber of pulse reaches corresponding second umber of pulse of this descending process, change
Frequency device 100 then controls door curtain to reduce speed now operation.When door curtain stops descending, if frequency converter 100 judges N<When 0, then it represents that
Door curtain location at the end of this is descending has exceeded lower position, then frequency converter 100 then increases the second umber of pulse, example
The second umber of pulse is such as updated to C+ | N ︱, so as to be advanced by the time that door curtain reduces speed now during next time is descending.If become
Frequency device 100 judges N>0, then it represents that door curtain location at the end of this is descending is no to reach lower position, then frequency conversion
Device 100 then reduces the second umber of pulse, for example, the second umber of pulse is updated into C-N, so as to delay door curtain in next descending process
In time for reducing speed now.
It is understood that the specific control mode of frequency converter 100 is not limited to above-mentioned situation, if the shape of such as electric signal
Formula is converted, or up process and it is descending during changed on the statistical of umber of pulse (such as once
It is continuous it is up, descending during, umber of pulse is counted according to gradually incremental mode all the time) when, the control mode of frequency converter 100
To occur respective change, with cause door curtain next time it is up at the end of and it is descending at the end of respectively not completely in place.
Specifically, for above-mentioned quick rolling-door control system, encoder 200 produces two groups of phases according to the angular displacement of motor
Potential difference is 90 degree of pulse signal, i.e. encoder 200 can export two mutually orthogonal group pulse signals, such as encoder 200
It can be incremental encoder.
So, frequency converter 100 is according to this two group pulse, and it is high both to have learnt door, again can be according between this two group pulse
Relation judge the direction of rotation of motor, and then judge that door curtain is in uplink state or downstream state.Encoded with increment type
Exemplified by device, it exports the pulse signal A and B that two-way phase differs 90 degree, and when motor is rotated forward, pulse signal A phase is advanced
90 degree of pulse signal B phase；When motor reversal, pulse signal A delayed phase pulse signal B 90 degree of phase, therefore
It is that can determine the steering of motor according to advanced and delayed relation, so that it is determined that upstream or downstream.Further, since using two-way
Orthogonal pulse signal, in the case of there is any unusual fluctuation in motor, all can accurate recording unusual fluctuation pulse, do not influence
The accuracy of uplink and downlink in place, and accumulated error will not be produced.
Further, for above-mentioned quick rolling-door control system, on the premise of electric signal is pulse signal, frequency converter
100 go back in terms of the high study of door while according to two kinds of situations being hampered in place and according to pulse in place under compatibility-use encoder pattern.
Wherein, according to being hampered in place, i.e., door curtain runs to door two ends the situation that stall occurs for motor, and frequency converter 100 can root
Judge whether to be hampered according to the moment variations of itself, so as to identify that door curtain has been running for one end of door.According to pulse
In place, i.e. door curtain runs to door two ends motor and will not occur the situation of stall, also, frequency converter 100 is according to arteries and veins set in advance
Number is rushed to control door curtain out of service by electric system 300.
Wherein, in the case where quick rolling-door is according to being hampered in place, the mode of the high study of door is：Frequency converter 100 is used
In the case of in door curtain according to being hampered in place, door curtain is controlled to perform up process or descending process by electric system 300, with
Door is learnt by umber of pulse high.Therefore, in the case where door curtain is according to being hampered in place, it is high that frequency converter 100 can learn door automatically.
Also, frequency converter 100 can open the high automatic learning process of door receiving the enabling signal of operator's input.It is high certainly in door
In dynamic learning process, the control door curtain of frequency converter 100 performs a upstream or downstream process, afterwards, is stopped according to door curtain in minimum point
A high corresponding range pulse number may be learned in umber of pulse when umber of pulse and peak when only stop, frequency converter 100.Example
Such as：If the corresponding umber of pulse of minimum point is 0, the corresponding umber of pulse of peak is 20, then range pulse number is 20.
Specifically, the one of which concrete mode of the high study of above-mentioned door is：Frequency converter 100 specifically in door curtain according to chance
In the case of resistance in place, door curtain is controlled to perform once up process and once descending process (example respectively by electric system 300
Such as：First carry out it is up perform again it is descending, or first carry out it is descending perform again it is up), and judge it is up during from starting knot
The umber of pulse received altogether between beam with it is descending during from start to end between the umber of pulse that receives altogether it is equal when, terminate door high
Study.At this moment, during up from start to end between the umber of pulse that receives altogether or it is descending during from start to end it
Between the umber of pulse that receives altogether be and the high corresponding range pulse number of door.
Specifically, the concrete mode of the high study of above-mentioned door can also have the scheme further refined, i.e.,：Frequency converter 100 has
Body is used in the case where door curtain is according to being hampered in place, controls door curtain to perform once up process respectively by electric system 300
Once descending process is (i.e.：Perform door high self study process for the first time), and judge it is up during from start to end between
The umber of pulse received altogether with it is descending during from start to end between the umber of pulse that receives altogether it is whether equal, if so, then terminating
The high study of door；Otherwise, control door curtain continuously performs once up process again and once descending process is (i.e.：Perform again above-mentioned
The high self study process of door), and judge it is up during from start to end between the umber of pulse that receives altogether with it is descending during from
Whether the umber of pulse received altogether between start to finish is equal, circulates successively.
Wherein, control door curtain continuously performs once up process and once descending process, refers in each cyclic process all
Need to perform once up and once descending process, in order to compare umber of pulse that the two processes receive respectively whether phase
Deng.For example：Execution setting number of times (such as 3 times) above-mentioned high self study process of door can be at most circulated, if setting number of times terminates
Afterwards, the executory up process of last time from start to end between the umber of pulse that receives altogether with descending process from starting knot
The umber of pulse received altogether between beam is still unequal, then can send alarm signal, so that operator checks in time, finds out event
Barrier.
It is understood that in the case where quick rolling-door is according to being hampered in place, the mode of the high study of door is not limited to
Above-mentioned situation, as long as frequency converter 100 can be by controlled motor system 300 and high to door using umber of pulse study.
In the case where quick rolling-door is pulse in place, the mode of the high study of door is：Frequency converter 100 is additionally operable in door curtain
In the case of according to pulse in place, door curtain is controlled to bring into operation by electric system 300 under control of the operator, and in door curtain
The signal inputted respectively according to operator when reaching minimum point, peak is out of service, thus according to it is out of service when pulse
It is high that mathematics practises door.
Wherein, in the case where quick rolling-door is according to pulse in place, if not done by the high study of door, then frequency converter
100 be that can not learn the minimum point and peak of quick rolling-door.At this moment, can be by manually starting the high study of door, i.e.,
Brought into operation by operator's control quick rolling-door, and control quick rolling-door is out of service when door curtain reaches minimum point, this
When frequency converter 100 can recognize minimum point；In addition, operator can also control door curtain to be controlled quickly when running to peak again
Rolling screen door is out of service, and at this moment frequency converter 100 can recognize peak, when frequency converter 100 recognizes minimum point and peak
Complete a high study afterwards.
It is understood that in the case where quick rolling-door is according to pulse in place, the mode of the high study of door is not limited to
Above-mentioned situation, as long as frequency converter 100 can finally learn the minimum point and peak to quick rolling-door.
In addition, after frequency converter 100 completes high study, you can the acceleration and deceleration operation for automatically generating quick rolling-door is bent
Line, so as to control the operation of quick rolling-door according to the acceleration and deceleration operation curve.
Further, Fig. 2 is refer to, above-mentioned quick rolling-door control system also supports stroke except supporting coding mode
Switching mode, be specially：Frequency converter 100 can also be electrically connected with multiple travel switches 400 for being installed on door curtain both sides.
Specifically, based on said structure, frequency converter 100 is additionally operable to according to connecing that the travel switch 400 of diverse location is sent
Touch signal accordingly controls door curtain to slow down or out of service during up by electric system 300, or in descending process
Middle deceleration or out of service.Wherein, activation signal refers to that door curtain is opened after touching travel switch 400 in the process of running by stroke
Close the signal of 400 outputs.
For example：It can need to set a travel switch 400 (to be defined as at the position slowed down during door curtain is up：
