Detailed description of the invention
Be described referring to accompanying drawing several embodiments to elevator involved in the present invention.
First embodiment
Fig. 1 to Fig. 3 is the figure of the embodiment representing elevator involved in the present invention, and wherein, Fig. 1 is the schematic diagram of 100 of so-called electronic safe elevator, shows the inside of hoist trunk 90 in the drawings.Fig. 2 is the block diagram of the control part of the electronic safe elevator 100 shown in Fig. 1, and Fig. 3 is the exemplary plot of the control flow of the electronic safe elevator 100 shown in Fig. 1.
As shown in Figure 1, the car 10 of elevator 100 is linked with speed controller rope 20.By this speed controller rope 20, governor 21 is arranged near the floor of hoist trunk 90.The car 10 of elevator 100 is also connected with the end side carrying out being elevated the main hoist cable 50 driven to this lift car 10.Its another side is connected with counterbalanced weight 40 by main hoist cable 50 after being wound on multiple rope sheave.The pars intermedia of main hoist cable 50 is wound on rope sheave, and this rope sheave is arranged on the S. A. of drive motor 30.
On the axle of drive motor 30, the impulse deviser (coder) 31 exporting the pulse count corresponding with the amount of movement of lift car 10 is installed in the mode directly linked.At the peripheral part of the rope sheave of drive motor 30, relative mode is provided with multiple (being two in FIG) drg 32.Drg 32 clamps the rope sheave of drive motor 30 when emergency braking etc.The bottom surface of hoist trunk 90 is provided with multiple energy disperser 80, when the situation that the car 10 that contingency there occurs elevator 100 drops, cushions impact when dropping by energy disperser 80.
In electronic safe elevator, replace existing mechanical limit switch, be made up of the safety device of elevator electronic signal.Therefore, the control setup 60 of elevator, except having the electric life controller 61 for controlling elevator lifting action, also has the safety governor 62 for guaranteeing elevator safety.
From be arranged on drive motor 30 with the amount of movement of lift car 10 correspondingly export the impulse deviser 31 of pulse signal 311 and detect from the floor in order to detect each floor be arranged on elevator lobby floor near the detection signal 71 of position detector 70 of tested drafting board 75 be imported in the controller 61 of elevator.Above-mentioned come the signal 311,71 of self-detector 31,70 for controlling the position of the car 10 of elevator 100.Position detector 70 is arranged on the position by opening and closing reveal of the base plate of lift car 10.
On the other hand, the S. A. of governor 21 is provided with multiple impulse deviser 22a, 22b or there is the coder of two A phases and B phase respectively.The output 221,222 of above-mentioned impulse deviser 22a, 22b or coder is imported in safety governor 62.This output 221,222 is also for the breakdown judge (details exporting 221,222 illustrates in aftermentioned part) of impulse deviser 22a, 22b.
Fig. 2 is the block diagram representing safety governor 62 and electric life controller 61.Safety governor 62 has distance count section 621,622, and the detection signal 221,222 from impulse deviser 22a, 22b of being arranged on governor 21 is imported in this distance count section 621,622.Equally, be imported in the distance count section 611 that electric life controller 61 has from the detection signal 311 of the impulse deviser 31 be arranged on drive motor 30.
In each distance count section 621,622 of safety governor 62, the impulse singla 221,222 of inputted governor 21 is converted to distance in units of mm from pulse count.The impulse singla 311 of inputted drive motor 30 is converted to distance in units of mm from pulse count by the distance count section 611 of electric life controller 61.
Safety governor 62 has the distance count value comparing section 623 compared the output signal 631,632 of two distance count section 621,622.Compare each other two output signals 631,632 in distance count value comparing section 623, according to comparative result, safety governor 62 judges whether impulse deviser 22a, the 22b be arranged on governor 21 there occurs exception.In addition, the command signal 635 that the elevator that safety governor 62 generation makes elevator 100 proceed to run runs process 110 usually or the command signal 634 making elevator 100 out of service.
Output signal 631a, 631b of the distance count section 621,622 of safety governor 62 are imported in the distance counting comparing section 613 that electric life controller 61 has at any time.Changed by the detection signal 311 of the impulse deviser 31 be arranged on drive motor 30 and the signal 633 that obtains also is imported in this distance counting comparing section 613 at any time.
At this, in order to guard against either party or the both sides' et out of order in impulse deviser 22a, 22b of being arranged on governor 21, electric life controller 61 has the elevator halt instruction portion 612 elevator 100 being stopped when above-mentioned impulse deviser 22a, 22b occur abnormal.Elevator halt instruction portion 612 generates instruction 641 when impulse deviser 22a, 22b occur abnormal, performs elevator thus and stops process 120.Meanwhile, elevator halt instruction portion 612 also generates the instruction 642 of distance counting comparing section 613 action making electric life controller 61.
Electric life controller 61 has rescues operation grant instruction portion 614 and elevator prevention instruction department 615.When there occurs abnormal, when by distance counting comparing section 613 compare three impulse deviser 22a, 22b, 31 Output rusults δ below specified value, rescue and run grant instruction portion 614 to rescue the passenger in lift car 10, generate and lift car 10 is moved and the command signal 645 rescuing operation 130 making shutter door opening and closing.When there occurs abnormal, when by distance counting comparing section 613 compare three impulse deviser 22a, 22b, 31 Output rusults δ exceeded specified value, elevator prevent instruction department generates elevator is stopped at once elevator prevention process 140 command signal 646.In addition, incoming signal 631a, 632a, 633 are by constantly transmission range counting comparing section 613, but distance counting comparing section 613 is failure to actuate when usually running.
Be described in more detail using an example with the operation control flow of the reality of the elevator 100 of the elevator control gear 60 of said structure referring to the diagram of circuit shown in Fig. 3.
After the operation of elevator 100 starts, the output 221,222 of impulse deviser 22a, 22b of the governor 21 ceaselessly detected is converted to the signal 631,632 of the distance in units of mm in distance count section 621,622 from pulse count, and by its transmission range count value comparing section 623.Its difference δ is judged whether within specified value (being 5mm in the present embodiment) (step S401) in distance count value comparing section 623.
The detected value of two impulse devisers 22a, 22b owing to being the detected value obtained from same measuring object, so its difference should be 0.Even if be subject to the impact of external factor, its metrical error δ also should be less than or equal to 5mm.So when error delta is below 5mm, be judged as that the action of two impulse devisers 22a, 22b is all normal, generate the command signal 635 that elevator runs process 110 usually, elevator control gear 60 makes elevator 100 usually run (step S402).
In usually running, judge whether lift car 10 has arrived the floor (step S403) of being specified by calling or hall call in car by elevator control gear 60.When arriving the floor of specifying, terminate to call out corresponding control to this.When also not arriving the floor of specifying, turn back to step S401.
In step S401, when there is the deviation of δ > 5mm in the metrical error of any one producer in two impulse devisers 22a, 22b, be difficult to think to be caused by external factor such as the hoist cable elongations be wound on governor 21, so distance count value comparing section 613 is judged as that the operation itself that any one producer in impulse deviser 22a, 22b or two producers all there occurs fault or elevator 100 there occurs exception.Now, elevator halt instruction portion 612 generates the command signal 641 that the elevator that the lifting of elevator 100 is temporarily stopped stops process 120, and the lifting of lift car 10 is temporarily stopped (step S404).
Then, compare the detected value of the impulse deviser 31 be arranged on drive motor 30 and be arranged on the detected value of impulse deviser 22a, 22b on governor 21 in distance count value comparing section 613.This is that whether at least one producer there occurs fault in order to judge to be arranged in two impulse devisers 22a, 22b on governor 21.Be arranged on impulse deviser 31 on drive motor 30 for speeds control, because it needs to carry out integration to obtain location information, so usually do not use it for position control., as shown in this embodiment, because impulse deviser 31 is higher than the resolution of impulse deviser 22a, 22b of being arranged on governor 21, so can use as the impulse deviser generating a reference value.
Whether the error delta between the output judging the impulse deviser 31 on the output of the impulse deviser 22a of the side on governor 21 and drive motor 30 in distance count value comparing section 613 deviate from more than specified value (being δ=200mm in the present embodiment) (step S405).The output of the impulse deviser 22a of the side on governor 21 and as the impulse deviser 31 on the drive motor 30 of benchmark output between error delta at below 200mm time, be judged as that the action of impulse deviser 22a is normal, by rescue run grant instruction portion 614 send make lift car 10 move to nearest floor from temporary stopped position rescue operation 130 instruction (step S406).
After operation rescued by enforcement elevator, in elevator control gear 60, judge whether lift car 10 has arrived nearest floor (step S407) according to the output of impulse deviser 22a.When being judged as that lift car 10 does not also arrive nearest floor, turn back to step S406.When being judged as that lift car 10 has arrived nearest floor, the shutter door opening lift car 100 to allow under passenger after elevator, prevents elevator and moves (step S408).
In step S405, when error delta between the output of the impulse deviser 31 in the output and drive motor 30 of the impulse deviser 22a of the side on governor 21 is δ more than > 200mm, be likely that fault has appearred in impulse deviser 22a.Now, whether the error delta between the output judging the impulse deviser 31 on the output of the impulse deviser 22b of the opposing party on governor 21 and drive motor 30 in distance count value comparing section 613 is δ≤below 200mm (step S409).
When error delta between the output of the impulse deviser 31 in the output of impulse deviser 22b being judged as the opposing party and drive motor 30 is δ≤200mm, elevator control gear 60 is judged as that the action of this impulse deviser 22b is normal, run grant instruction portion 614 and send by rescuing the instruction 645 rescuing operation 130, and perform elevator and rescue operation (step S410).Rescuing after operation starts, according to the output of impulse deviser 22b, elevator control gear 60 judges whether lift car 10 has arrived nearest floor (step S411).
When being judged as that lift car 10 has arrived nearest floor, opening shutter door and allowing under passenger and terminate after elevator to rescue operation, after this preventing elevator 100 and move (step S412).When being judged as that lift car 10 does not also arrive nearest floor, returning step S409, repeatedly performing above-mentioned steps.
In step S409, if when the error delta between the output being judged as the impulse deviser 31 on the output of the impulse deviser 22b of the opposing party on governor 21 and drive motor 30 is δ > 200mm, be judged as that this impulse deviser 22b also there occurs fault or elevator 100 there occurs exception.Due in any one situation in above-mentioned situation, elevator all can not run further, carries out the command signal 646 that process 140 prevented by elevator, brake elevator 100 so generated at once by elevator control gear 60.Now, before maintainer arrives, passenger is trapped in lift car 10.
According to the present embodiment, when being arranged on the impulse deviser on governor and there occurs fault, except two impulse devisers all there occurs except the situation of fault, by implementing to rescue operation, elevator under the passenger that can allow rapidly in lift car, and do not need the arrival waiting for maintainer.In addition, even if when there is no adjacent elevator or when lift car arranges separately, also can by carrying out rescuing operation, do not need to wait for elevator under the passenger that the arrival of maintainer just can allow in lift car.
Say in more detail, even if the impulse deviser of the side in two impulse devisers on the sheave shaft being arranged on the governor used as safety device there occurs fault, when making to determine the position of lift car and carried out emergency braking, also can realize above-mentioned effect.That is, use the impulse deviser be arranged on the sheave shaft of drive motor, by the signal of three impulse devisers input electric life controller or safety governor, when the signal confirming as at least two impulse devisers is equal, performs and rescue operation.Thereby, it is possible to the state of affairs avoiding passenger to be closed in lift car occurs.

Fig. 4 to Fig. 6 represents another embodiment of elevator 100 involved in the present invention.Fig. 4 and Fig. 1 is corresponding, and be the schematic diagram of the hoist trunk 90 of elevator 100, elevator 100 wherein has mechanical safety device, and this mechanical safety device has limit switch of the prior art.Fig. 5 is the control block diagram of the elevator 100 shown in Fig. 4, and Fig. 6 is the control flow chart of the elevator shown in Fig. 4.The difference of the present embodiment and above-mentioned first embodiment is not have electric safety control-ler in the present embodiment.
In the elevator of prior art, elevator control gear 60 does not arrange electric safety control-ler, is only provided with electric life controller 61.In addition, in order to detect the position of lift car 10, tested drafting board 75 is had in each storey setting.When lift car 10 is elevated, detects this tested drafting board 75 by the position detecting device 70 being arranged on lift car 10 bottom, lift car is positioned at and there occurs on the floor of calling.
At the back side of lift car 10, arc cam is installed.On the other hand, in hoist trunk 90, the rising end position of lift car 10 is provided with upside final limit switch 81, and what separate regulation in the below of this final limit switch 81 is arranged at intervals with multiple tops limit switch 82,83.In hoist trunk 90, be provided with downside final limit switch 88 in the falling-threshold position of lift car 10, what on the downside of this, separate regulation above final limit switch is arranged at intervals with multiple lower limit switch 85,84.After cam 87 contacts with above-mentioned limit switch 81 ~ 86, limit switch 81 ~ 86 action, mechanically stops the exception of lift car 10 to rise and decline.
At this, in the present embodiment, be with the difference of prior art, install at governor 21 and there are two coders or two impulse devisers 22a, 22b exported, and its output signal 231,232 is input in electric life controller 61.The signal 351 of limit switch 81 ~ 86 and the signal 311 of impulse deviser 31 be arranged on drive motor 30 are also input in electric life controller 61.
Fig. 5 is the functional block diagram of the elevator control gear 60 shown in Fig. 4.The output signal 221,222 being arranged on impulse deviser 22a, the 22b on governor 21 is input to distance count value comparing section 613 after the range signal 631,632 that pulse count is converted in units of mm by being arranged on distance count section 616,617 in electric life controller 61.On the other hand, the output signal 311 being arranged on the impulse deviser 31 on drive motor 30 is converted to the range signal 651 in units of mm from pulse count in distance count section 611.
At this, although occurring that lift car 10 is moving the state of affairs that correctly cannot detect the number of the output pulse 311 of impulse deviser 31 apart from count section 611 to guard against, being provided with pulse and extremely judging handling part 618.This pulse is abnormal judges that handling part 618 is when there occurs the above-mentioned state of affairs, is judged as that elevator 100 there occurs exception.Only otherwise the above-mentioned state of affairs occurs, pulse is abnormal judges that handling part 618 is judged as that the action of elevator 100 is normal, and generation runs the command signal 652 of process 110 usually for performing elevator.When being judged as there occurs abnormal, send the instruction of abnormal signal 653 to elevator halt instruction portion 612.
Elevator halt instruction portion 612, while generating the instruction 654 for performing the elevator stopping process 120 making elevator 100 temporarily stop, generating the instruction 655 making the action of distance count value comparing section 613.Distance count value comparing section 613 is started according to the command signal 655 from elevator halt instruction portion 612, generates to make to rescue run the command signal 643,644 that instruction department 615 action prevented by grant instruction portion 614 or elevator according to the output of impulse deviser 22a, 22b in the output of the impulse deviser 31 on drive motor 30 and governor 21.Rescuing operation grant instruction portion 614 generates for performing the instruction 645 rescuing operation 130, and elevator is prevented instruction department 615 and generated the command signal 646 preventing process 140 for performing elevator.
Be described in more detail using an example with the real-world operation control flow of the elevator 100 of the elevator control gear 60 of said structure referring to the diagram of circuit shown in Fig. 6
After elevator 100 brings into operation, first judge whether lift car 10 is carrying out rising operation or declining running (step S701) by elevator control gear 60.Be judged as lift car 10 carry out rising run or decline run time, judge that handling part 618 judges to be arranged on impulse deviser on drive motor 30 31 whether in the pulse (step S702) that output is corresponding with the amount of movement of lift car 10 by pulse is abnormal.
When being judged as that the action of impulse deviser 31 is normal, pulse is abnormal judges that handling part 618 generates the command signal 652 that elevator runs process 110 usually, to perform usual operation (step S703).After this judge whether lift car has arrived the floor (step S704) of being specified by calling or hall call in car.When being judged as arriving, terminate to call out corresponding control to this.When also not arriving the floor of specifying, turn back to step S701, and perform the step of step S701 to step S704.In step s 701, both do not rise at lift car 10 and do not declined yet, when namely remaining static, performed step S701 according to the time gap of regulation.
When being judged as that in step S702 the output of impulse deviser 31 there occurs abnormal, enter step S705, elevator stops processing section 612 to generate the command signal 654 of elevator stopping process 120, makes the rising of lift car 10 or decline temporarily to stop (step S705).Meanwhile, distance count value comparing section 613 is started, the output of impulse deviser 22a, 22b of being arranged on governor 21 is compared (step S706) mutually.
When the error delta of the output of distance count section 616,617 is δ≤200mm, the action of impulse deviser 22a, 22b is considered as normally, make to rescue and run grant instruction portion 614 action, generating the command signal 654 for rescuing operation 130, starting to carry out rescuing operation (step S707).When there is the deviation of > 200mm in the error delta of the output of distance count section 616,617, elevator is made to prevent instruction department 615 action, generate the command signal 646 preventing process 140 for carrying out elevator, and elevator 100 is stopped mobile (step S710).
Elevator 100 rescue operation 130 start after, make lift car 10 move to nearest floor.In elevator control gear 60, judge whether lift car 10 has arrived nearest floor (step S708).When being judged as that lift car 10 does not also arrive nearest floor, returning step S706, repeatedly performing the step of step S706 to step S708.When being judged as that lift car 10 has arrived nearest floor, making lift car 10 keep quiescence, opening elevator door and allowing elevator under passenger, after this preventing elevator 100 and move (S709).
According to the present embodiment, only need the coder installed two impulse devisers in the governor side of the elevator of prior art or two signals (there are two A phases and two B phases) can be exported, just can carry out rescuing operation.That is, even if on the sheave shaft being arranged on drive motor, impulse deviser there occurs fault, when making to determine the position of lift car and carried out emergency braking, the signal of two impulse devisers be arranged on the sheave shaft of governor also can be used to carry out rescuing operation.Thereby, it is possible to reduce the generation that passenger is closed in the accident in lift car.In addition, when being arranged on the impulse deviser on governor and there occurs fault, except two impulse devisers all there occurs except the occasion of fault, can perform and rescue operation, elevator under the passenger that can allow rapidly in lift car thus.Thus, do not need to wait for that the arrival of maintainer just can alleviate the burden of passenger.In addition, even if when there is no adjacent elevator or when lift car arranges separately, also can by carrying out rescuing operation, do not need to wait for elevator under the passenger that the arrival of maintainer just can allow in lift car.
