In elevator, as shown in Figure 1, the lift car of taking for the passenger 1 is connected with counterbalanced weight 3 by main rope 2, and main rope 2 is wound on rope sheave 4 and the deflection sheave 5.Rope sheave 4 is driven by drive motor 6, and this drive motor 6 drives electricity consumption by power conversion unit 7 supplies.In addition, when the detection of the vertical direction position of the equivalence of speed of carrying out drive motor 6 and lift car 1 and miles of relative movement etc., count by the pulse of impulse deviser 8 outputs by 9 pairs of rotations of system control device, to calculate various controlling quantitys along with drive motor 6.At this, because impulse deviser 8 is along with the rotation of drive motor 6 produces pulse, therefore can correctly carry out speed to drive motor 6 detects, but can being subjected to the position of influence, especially lift car that the adhesion between rope sheave 4 and the main rope 2 drives, the speed of the reality of the lift car 1 by 2 suspentions of rope sheave 4 and main rope and position etc. can produce error because of small slip.In addition, in the elevator of the high skyscraper of hundreds of rice, the influence that the acceleration-deceleration of the lift car during main rope is travelled changes, telescopic variation can take place in its length, and the position of the lift car that the pulsimeter that produces according to impulse deviser calculates does not reflect stretching of main hoist cable etc., therefore, in order to carry out described later and position control corresponding (this is controlled in the known technology and did not implement) lift car, preferably obtain the high elevator car position information of reliability.At this, to be wound on the upper and lower side bonded assembly rope 10 of lift car 1 on the pulley 11,12, and on the pulley 11 of rotation, connect another impulse deviser 13 along with moving of lift car 1, the output of impulse deviser 13 is input to system control device 9, with the actual position corresponding value of calculating with lift car 1.
Be provided with elevator cab door 14 in the lift car 1, elevator door electrical motor 15 produces door closing force.In addition, also be provided with can detect whether elevator cab door 14 close fully close detector 16 fully, what also have the amplitude of opening that can detect elevator cab door 14 simultaneously opens range detector 17, and the output signal of these detectors 16,17 is sent in the lift car terminal 18.
The building side be respectively arranged with can be respectively relative with each car door 14 of N-1 layer, N layer and N+1 layer to elevator lobby door 24N-1,24N, 24N+1.In addition, also be provided with can detect whether elevator lobby door 24N-1,24N, 24N+1 close fully close detector 26N-1,26N, 26N+1 fully, what also have the amplitude of opening that can detect elevator lobby door 24N-1,24N, 24N+1 simultaneously opens range detector 27N-1,27N, 27N+1, and the output signal of these detectors 26N-1,26N, 26N+1,27N-1,27N, 27N+1 is sent to each floor terminal 28N-1,28N, 28N+1.In addition, the information of lift car terminal 18 and each floor terminal 28N-1,28N, 28N+1 is sent in the system control device 9 by network 20, and system control device 9 carries out the operation of lift car 1 under the situation of the state of grasping 1 of all elevator lobby doors and lift car.
In addition, Fig. 1 represents that lift car 1 is in position and the situation when N-1 layer descends operation between N-1 layer and the N layer.At this moment, for example, if elevator cab door 14 and elevator lobby door 24N-1,24N, the 24N+1 Close All, then close detector 16 fully and open the output signal that range detector 17 will represent that respectively elevator cab door 14 is in closed condition and send to lift car terminal 18, simultaneously, close detector 26N-1 fully, 26N, 26N+1 and open range detector 27N-1,27N, 27N+1 will represent elevator lobby door 24N-1 respectively, 24N, the output signal that 24N+1 is in closed condition sends to each floor terminal 28N-1,28N, 28N+1, system control device 9 carry out the operation control of lift car 1 according to these information.
(1) at first, close detector 16,26i fully (when i=N-1～N+1) detects and closes whole, because whole elevator door, just the closed condition of elevator cab door 14 and elevator lobby door 24N-1,24N, 24N+1 has obtained affirmation, therefore the same with known elevator, be in the state that normal operation is not restricted.
(2) for example, in the travelling of lift car 1, by closing elevator lobby door 24N+1 that detector 26N+1 detects the N+1 layer fully when not closing fully, this information is sent in the system control device 9 by each floor terminal 28N+1, and determining after whether elevator lobby door 24N+1 has produced unusually this information to be sent to supervisory management zone, for example servicing center 21.On the other hand, the output that can grasp the impulse deviser 13 of lift car 1 operating state definitely also is sent to system controller 9, lift car 1 for example is in going to N-1 layer way the time, owing to be in the N+1 layer of open mode without elevator lobby door 24N+1, therefore being judged as does not need promptly to stop, and makes elevator continue operation according to safety mode.So, respectively the floor that problem has taken place is discerned by system control device 9, and the position and the service direction of identification lift car 1, by making lift car 1 continue operation in other zone of opening floor without elevator door unusually, not only can avoid coming in contact with lift car 1 moving from the object that the elevator lobby door that elevator door is opened floor unusually reaches in the hoist trunk, accomplish to guarantee safety, can also make elevator continue operation simultaneously, therefore can make things convenient for the passenger.
(3) after the operation of above-mentioned (2), lift car 1 is through with and is in readiness for action after the service to the passenger, therefore, 9 pairs of elevator doors of system control device are opened floor N+1 layer unusually and are discerned, automatically produce the elevator-calling login, making lift car 1 is the N layer at the next floor that security operating mode is moved to this floor, lift car is at the N layer stops and readiness for action.Thus, even just in case open floor unusually from elevator door is that the N+1 layer is when having taken place to fall etc., because it is the N layer that lift car 1 stops at the next floor of this floor, therefore ceiling can be accepted the object of whereabouts on the car of lift car 1, so as system, at falling accident, can bring into play the effect that further tightens security.
(4) medium on the way of the continuation operation of above-mentioned (2) etc., when being arranged on the opening the amplitude of opening that range detector 27N+1 detects elevator lobby door 24N+1 and become big and surpassed the specified value of predesignating of N+1 layer, perhaps when other open open mode that range detector 17,27N, 27N-1 detect elevator door and surpassed the specified value of predesignating, consider and to fall or danger such as contact, the same with known technology, stop the operation of lift car 1 at once, to guarantee safety.
(5) similar to the situation of above-mentioned (4), open range detector 17 when elevator cab door 14, the output of opening range detector 27i of elevator lobby door 24i hour, the amplitude of opening that promptly is judged as elevator door does not have to surpass the specified value of predesignating, therefore object can not occur falls, in the time of situation that equipment etc. in lift car 1 and the hoist trunk comes in contact etc. can not occurring yet, with above-mentioned (2), (4) difference, the permission elevator is opened floor unusually through elevator door and is allowed the very little lift car of the amplitude of opening 1 to continue operation, thus, not only have and to guarantee safe effect actually, but also can make elevator continue operation, thereby can make things convenient for passenger's effect.
(6) when detecting elevator lobby door or elevator cab door and taken place to open unusually, the same with above-mentioned (5), if aperture is very little, then guaranteeing on the safe basis, automatically produce and call out, make lift car 1 drive to elevator door and open floor unusually, and open floor unusually at elevator door and implement the switching inspection action of elevator door for several times, have no abnormal with observation.Perhaps, after opening and closing the inspection end, make lift car 1 move to other floor, according to observing the situation of change that elevator door is opened the state of closing the door of floor unusually by the information that network 20 sends to the system control device 9 from each floor terminal 18i.Thus, can check therefore also have the effect of the direction of maintaining to action.
Following diagram of circuit according to Fig. 2 to Fig. 8 is elaborated to various security operating modes.
The computing of required various basic numerical value and judgement should be implemented the step that the judgment processing F10 of safe operation is still implemented in normal operation when Fig. 2 represented to judge whether to implement security operating mode.This processing is very important concerning the judgement of the security operating mode that needs high reliability, need carry out with certain interval termly at ordinary times, therefore it is arranged to carry out with the timer starting task dispatching starting of not shown arithmetic system.At first, after the starting of this task, in handling F110, carry out the inspection of the action of the calculating of elevator car position and impulse deviser 8,13.The calculating of elevator car position, the same with known technology, carry out integrating by 8,13 pulses that produced of paired pulses producer and realize.On the other hand, whether the action checking of impulse deviser 8,13 exists big difference to realize by the positional value of obtaining according to the output of impulse deviser 8,13 is respectively compared between the two to judge.Afterwards, in handling F120, confirm the service direction of lift car 1.Usually, calculate according to the context of the 2 kinds of pulses that comprise in the impulse deviser 8,13 with phase difference.After this, in handling F130, confirm the predetermined stop floor of lift car 1.Above-mentioned 3 kinds of information are to judge important factor of judgment when implementing various security operating mode described later according to the relation of following position of opening the door and aperture etc.Afterwards, in handling F140, read and confirm to detect whether the elevator cab door 14 of lift car 1 close fully closes detector 16 fully and detect the information of closing detector 26i fully whether the elevator lobby door 24i of each layer closes fully through network 19,20.And, by in servicely on-off action being monitored the action checking that carries out these detectors 16,26i with static mode when resting in each floor normal at lift car 1.In handling F150, the information of opening range detector 27i of opening range detector 17 and can detecting that reads and confirm to detect through network 19,20 to the amplitude of opening of the elevator lobby door 24i of each floor to the amplitude of opening of the elevator cab door 14 of lift car 1.And,, carry out the action checking of these detectors 17,27i with this by in servicely when lift car 1 is stopped each floor, splitting closed procedure and monitor with dynamical fashion normal.After this, in handling F160, according to detector 16,26i, 17, the information of 27i diagnoses the elevator lobby door 24i of the current stop floor floor in addition of lift car 1 whether to be in open mode, perhaps when travelling, lift car 1 whether has the elevator door 14 that is in open mode, 24i, if there is the elevator door that is in open mode, then in handling F170, the degree of opening by elevator door and the position of lift car and service direction etc. enter various security operating modes and carry out judgment processing, if there is no be in the elevator door of open mode, then in handling F180, elevator is moved normally, in handling F190, turn back to the bootwait state, to wait for timer interrupt handling next time.
Fig. 3 represents to judge according to the aperture of elevator door the step of the processing F170 that carry out what kind of security operating mode and implement.At first, because anomalous behavior has appearred, this pattern starting, and this situation that at first will take place to open the door unusually in handling F1701 is to servicing center 21 contacts.At this moment, at which floor and which lift car elevator door having taken place and opened this information of fault unusually, concerning rapid place under repair and checking, is very important information, therefore at first sends this information to servicing center.In addition, in following security operating mode, system can be subjected to some restrictions aspect operation, therefore, from obtaining passenger's understanding equal angles, is not to be in fully normal this situation of running state to tell that elevator passenger is useful with elevator.Afterwards, in handling F1702, according to from opening the information of opening range detector 17,27i that amplitude detects to elevator door, whether the aperture of judging elevator door is less than the 1st specified value of predesignating.At this moment, if the aperture of elevator door is less than the 1st specified value of predesignating, be that the degree that elevator door is opened is to point when waiting degree of stretching, then owing to the possibility that comes in contact accident and nipped accident etc. is few, therefore will implement the operation identical and handle F20 for the passenger provides convenience as action points with normal operation.But, in this case, because elevator is not to be in fully normal state, therefore in handling F60, for example when the passenger is less, call out login automatically, elevator is driven to be judged as elevator door and open floor unusually, the elevator lobby door is implemented to open and close test, attempt to eliminate sporadic fault, perhaps by following the tracks of and confirm to collect the required information of maintenance examination of carrying out to leaving detector output behind this floor, and through handling the processing that turns back to beginning behind the F1704.On the other hand, if whether the aperture that is judged as door in handling F1702 during greater than the 1st specified value predesignated, judges aperture less than the 2nd specified value of predesignating in handling F1703, judge just whether aperture is moderate aperture.At this moment, if when judging aperture less than the 2nd specified value predesignated, in processing F30 described later, implement the safe operation that adapts with moderate elevator door aperture, afterwards, implement to handle F50 as required, so as with the damage control of object when the elevator door of opening falls in Min., afterwards through handling the processing that F1704 gets back to beginning.If when the aperture of judgement elevator door is big in handling F1703, in handling F40, implement and the big corresponding processing of elevator door aperture F40, afterwards through getting back to the processing of beginning behind the processing F1704.So, in scheme proposed by the invention, carry out multiple security operating mode according to the closed condition of each floor or 1 14 of lift car, 24i, rather than as known technology, only carry out a kind of processing.In addition, handling F20, processing F30, processing F40 and processing F50 partly is elaborated in aftermentioned.In addition, above-mentioned the 2nd specified value is set to the value bigger than the 1st specified value, in the present embodiment, it is little that aperture is set at the elevator door aperture less than the situation of the 1st specified value, greater than the 1st specified value but to be set at the elevator door aperture less than the situation of the 2nd specified value medium, it is big that aperture is set at the elevator door aperture greater than the situation of the 2nd specified value with aperture.And it is very little that the 1st specified value is set to aperture, even will point and foreign matter etc. does not also have the value of the danger of accidents such as coming in contact from elevator lobby door 24i and elevator cab door 14 when the hoist trunk side is stretched out.
Fig. 4 represent because of the elevator door aperture less, so the security operating mode that makes elevator keep original operation is basically handled the step of F20.Implement security operating mode in the aperture of elevator door during less than the 1st specified value predesignated and handle F20, at first in handling F201, no matter whether be the floor that elevator door is in open mode, also no matter the position of lift car how, in order to provide service to all callings, carry out the operation that is close with normal operation, take elevator to make things convenient for the passenger.The prerequisite of this processing is that the aperture of elevator door is very narrow, even will point and foreign matter etc. stretches out the danger that does not also have accidents such as coming in contact from elevator lobby door 24i and elevator cab door 14 to the hoist trunk side.Just, this moment, elevator was not to be in fully normal state, so the aperture state to elevator door monitors unceasingly in handling F202, as illustrated among the processing F1701 of Fig. 3, proceeded operation according to maintainer's requirement.Then, through handling end process after the processing that F203 gets back to beginning.In this security operating mode, if judge that the elevator door aperture is very little, and the possibility of causing danger also hour is determined inspection area and is guaranteed safety according to maintainer's requirement, proceed operation simultaneously, to obtain the making things convenient for passenger to take the effect of elevator.
It is moderate that Fig. 5 is illustrated in the elevator door aperture, the step of the security operating mode F30 that is implemented when just the aperture of elevator door is greater than the 1st specified value of predesignating but less than the 2nd specified value.This pattern is different with the security operating mode of implementing under the less situation of aperture shown in Figure 4, has made some restrictions aspect operation, to scheme taking elevator guaranteeing to continue operation under the safe situation to make things convenient for the passenger.When this handled the F30 starting, at first, in handling F301, stoping elevator to go to the aperture of elevator lobby door to be detected as moderate floor provided service.This processing has the equipment that can avoid in lift car 1 and the hoist trunk etc. and is that moderate gap reaches the effect that the foreign matter in the hoist trunk comes in contact by aperture.And, in handling F302, judge that the current location of lift car 1 and the position that elevator door is opened between the floor unusually concern, when the current location that is judged as lift car is positioned at elevator door and opens the top area of floor unusually, in handling F303, allow to continue operation in the zone of elevator above elevator door is opened floor unusually, and in handling F304, stop elevator to open floor unusually and run to the below floor through elevator door.Thus, can avoid opening floor unusually and come in contact accident, can proceed operation simultaneously again to provide convenience to the passenger at elevator door.In addition, in contrast, in handling F302, if judge when lift car 1 is positioned at elevator door and opens the below floor area of floor unusually, in handling F305, make elevator not come in contact dangerous lower region continuation operation to provide convenience, simultaneously in handling F306 to the passenger, stop elevator to open floor unusually and run to the top floor, to avoid the accident of coming in contact through elevator door.In addition, more than explanation is the either party of the hypothesis elevator lobby door 24i step when having taken place to open the door unusually, when if to detect the unusual aperture of elevator cab door 14 be moderate, because lift car 1 all might come in contact with foreign matter in any position, therefore, have to stop to continue operation, make elevator be accommodated to nearest floor as early as possible with the deceleration/decel of normal operation in order preferentially to guarantee safety, and the operation after the cancellation.But, in the present embodiment, after the elevator door aperture that detects elevator cab door 14 is moderate, owing to can make elevator run to nearest floor, therefore, can avoid taking place, thereby can guarantee MIN comfort feature because of the situation that promptly stops to cause the passenger to be closed in lift car.
The step of the security operating mode F40 that Fig. 6 is illustrated in the big occasion of elevator door aperture, implement when just the aperture of elevator door is greater than the 2nd specified value predesignated.At first, can judgement just stop floor with normal deceleration/decel at operating lift car 1 under the situation of opening floor without elevator door unusually in handling F401.When can be when stopping floor under the situation of opening floor without elevator door unusually, in handling F402, automatically produce calling by system control device 9, make elevator parking open on the previous floor of floor unusually at elevator door, make the passenger under this stop layer, avoid taking place the passenger with this and be closed in accident in the lift car.On the other hand, can not be when stopping floor under the situation of opening floor without elevator door unusually if in handling F401, be judged as with normal deceleration/decel, from precarious position being controlled at this viewpoint in the shortest time, in handling F403, elevator emergency is stopped.Afterwards, in handling F404, judge whether lift car 1 can be moved to the next floor that elevator door is opened floor unusually in the situation of opening floor without elevator door unusually, at this moment, can be when the situation of opening floor without elevator door unusually be moved to elevator door and opens the next floor of floor unusually if be judged as lift car 1, in handling F405, make lift car 1 move to the next floor that elevator door is opened floor unusually, and it is rested on this floor.Thus, the ceiling of lift car 1 can be brought into play and catch the effect of opening the foreign matter that floor falls down from elevator door unusually.On the other hand, can not be when the situation of opening floor without elevator door unusually be moved to elevator door and opens the next floor of floor unusually if in handling F404, be judged as lift car 1, compare with the effect of catching foreign matter, preferentially avoid when opening floor unusually and risk that foreign matter comes in contact, in handling F406, continue to implement to stop to handle by elevator door.And, open the example that is treated to that the next floor of floor stops unusually and be described to move to elevator door at this, still, in employed elevator of high building etc., some zone is set to the zone of not stopping and directly passing through.At this moment, self-evident, elevator is moved to opens unusually on the non-floor position in below of floor to stop near elevator door, also can bring into play the effect of catching falling objects.In addition, this with elevator lobby door 24i taken place aperture big open unusually the time situation be example is illustrated operating procedure, and when detecting 1 14 of lift car the big situation about opening unusually of aperture taken place, then pay the utmost attention to safety, set the urgency of this moment for be higher than above-mentioned processing F30 occasion, lift car 1 is promptly stopped.
It is moderate that Fig. 7 is illustrated in the elevator door aperture, the treatment step of implementing when just the aperture of elevator door is greater than the 1st specified value of predesignating but less than the 2nd specified value that prevents from model F 50.This handles identical with the processing F404～F407 that handles F40 basically, after the passenger is gone down from lift car 1, in handling F501, judge whether lift car 1 can be moved to the next floor that elevator door is opened floor unusually in the situation of opening floor without elevator door unusually, at this moment, if lift car 1 can be when the situation of opening floor without elevator door unusually be moved to elevator door and opens the next floor of floor unusually, in handling F504, make lift car 1 move to the next floor that elevator door is opened floor unusually, and make it rest in this floor, to catch the object that falls down from elevator lobby door 24i.Then, as handling shown in the F505, elevator does not respond and enters readiness for action the calling of the elevator passenger of generation afterwards.On the other hand, can not be when the situation of opening floor without elevator door unusually be moved to elevator door and opens the next floor of floor unusually if in handling F501, be judged as lift car 1, compare with the effect of catching foreign matter, preferentially avoid when opening floor unusually and risk that foreign matter comes in contact, in handling F502, continue to implement to stop to handle by elevator door.
The detailed process step of the processing F60 that Fig. 8 implements when being illustrated in degree that elevator door opens less than the 1st specified value predesignated.At first, in handling F601, produce speed command, elevator is run to be detected the floor that the elevator lobby door is opened.Then, after having arrived the object floor, in handling F602, carry out the on-off action of this elevator lobby door.Afterwards, in handling F603, read the signal of closing detector 26i fully of closing detector 16 and building side fully of lift car 2, and both are compared.Afterwards, further in handling F604, read the signal of opening range detector 27i of opening range detector 17 and building side of lift car 2, and conduct a survey both being compared laggard action.Then, judge in handling F605 whether the closing movement of elevator door and switching degree detected value are improved, and being judged as when improving, change normal operation mode into, cancellation " having found to open the door unusually " this notice in handling F606 from security operating mode.On the other hand,, then continue the situation that elevator door is opened is unusually notified, then through end process behind the processing F607 if in handling F605, be judged as when not improving.According to this Actuator Test Modes again, can avoid elevator to open and detect and situation that fault that aperture detects makes operation stop always takes place because of sporadic elevator door, can avoid so make troubles to the passenger.
According to present embodiment, be in relative at elevator lobby door 24i with elevator cab door 14 to state, when simultaneously lift car 1 is in elevator lobby door specific under the condition beyond this condition of halted state or elevator cab door and opens, switching degree according to each elevator door, the information of the position of lift car and service direction etc., when avoiding lift car and the foreign matter that from the opening portion of opening unusually, stretches out to come in contact accident, by making elevator reasonably continue operation, can in possible zone, make things convenient for the passenger, alleviate the inconvenience that brings to elevator passenger.In addition, by set up make lift car 1 elevator door open unusually floor below the whereabouts of standby prevent pattern, utilize lift car 1 to catch the object that falls down from opening portion, can improve safety.And, when aperture is very little, make elevator device carry out OBD (On-Board Diagnostics) and the oneself resets by Actuator Test Modes again, can avoid operation and unnecessary stopping to occur, thereby can improve operating efficiency.
In addition, inform servicing center 21, can shorten the effect that completes repairs and check the required time so have because unusual position will take place.And, inform elevator passenger by will carrying out this content of security operating mode, elevator passenger can be known having or not restriction aspect the elevator use, also have the effect that improves passenger's satisfaction.And, many group detectors 16,17,26i, the 27i elevator door opening-closing when normal operation are in the state that connects or disconnects together when moving, therefore by according to its action checking of regularly implementing detector termly, have the very high safety and the system of comfort feature all the time with regard to making up.In addition, the impulse deviser 8,13 that elevator car position detects usefulness has the very high safety and the system of comfort feature all the time by implementing action checking termly mutually when the travelling of normal operation, can making up.
In addition, to be used for the anglec of rotation that range detector is arranged to directly to detect the elevator door electrical motor 15 that drives 14 of lift cars of opening that aperture to elevator cab door 14 detects, perhaps not having sensor infers, perhaps infer by the signal of bonded assembly impulse deviser in order to measure the anglec of rotation or speed for basis, can cost-cutting.
