The danger signal input that the expression elevator of braking assist torque control part 907 control parts of autokinesis in the future 901 stops to start with, the door that the door 13 of expression car 1 that continue to accept to open from door sensor 15 is opened open signal during, output according to car position operational part 903 or car position sensor 11, the position of the position of judging car 1 when stopping to produce departs from the then instruction that 908 outputs make electrical motor 5 produce the braking assist torque to braking assist torque instruction department.Even this braking assist torque control part 907 also can be exported this instruction when mobile the stopping of car 1, bring into operation up to car 1 after this, perhaps close up to the door 13 of car 1.That is, it is to prevent from stop mode that door is being opened to depart from the instruction that stop position is used at least.Braking assist torque instruction department 908 is accepted the braking assist torque and is instructed, and makes drive control part 902 outputs produce the motor drive current that essential assist torque is used.
Even battery 909 is the electrical storage devices that possess in order also to keep basic function when having a power failure, not only available so-called lead battery also can be with formations such as secondary battery or fuel cells.The battery that this battery 909 is used to self-retention assist torque control part 907 connects signal, is connected supply power with drive control part 902.
Circular control part 910 makes circular device 16 work that are provided with on the car 1.Under the active situation of basic training of braking assist torque, when car 1 moved under the state that door is being opened, 910 pairs of circular devices 16 of this circular control part were controlled, the passenger of notice car 1, inform that car ground and stop ground are offset, perhaps circular is just utilizing basic function.In addition, this state is owing to surpass car 1 in sometimes under the situations such as the passenger of staffing takes advantage of and can take place, so also has and circulate a notice of effect that the passenger is withdrawed from from car 1.
The action of the apparatus for controlling elevator that present embodiment 1 is relevant is described with reference to the accompanying drawings.
In the following description, situation about balancing each other with 50% load of the staffing of the weight of counterweight 2 and car 1 is an example.
Figure 4 shows that the graph of a relation of load and unbalance load (counterweight compensation 50%) and the necessary braking force of magnet stopper.
In Fig. 4, % load is to be benchmark (100% load) with the weight of the staffing of car 1 (for example being 10 people among the figure) when taking a lift, and is loaded with the value of the load of how many % in the expression car 1, and it becomes the benchmark of the braking force of expression magnet stopper 6.According to Nippon Standard, magnet stopper 6 must have the ability that can make car 1 safety deceleration and static maintenance to the load of as many as 125%.In addition, according to European standard, mechanical brake as magnet stopper 6 must have two covers, as ability, must have the ability that when 125% load is descended, towing machine 8 is stopped with two cover drgs, lose under the situation of ability at 1 cover drg in addition, must have the ability that when 100% load is descended, towing machine 8 is stopped with single cover drg.
Such magnet stopper 6 is extremely important device for the safety of elevator, adopt the such high reliability mode of trouble free or mal, and the periodical maintenance maintenance is indispensable.But though be very rare situation, also will imagine has magnet stopper 6 to produce faults or mal and brakes hypodynamic situation.
The invention provides a kind of control setup 9, it is characterized in that, be parked in certain stop 12 and for passenger up and down and under door 13 states of opening of car 1 at car 1, although magnet stopper 6 is moving, but make the static confining force deficiency of magnet stopper 6 owing to certain mal, car 1 beginning is moved slightly, when detecting the anglec of rotation of electrical motor 5 with coder 7, in order to make car 1 be still in the position of stop 12, then drive control motor 5, make it produce the torque that stops these electrical motor 5 rotations.
In addition, the invention provides a kind of control setup 9, this control setup 9 is parked in certain stop 12 at car 1, and for passenger up and down and under door 13 states of opening of car 1, although magnet stopper 6 is moving, but make the static confining force deficiency of magnet stopper 6 owing to certain mal, car 1 beginning is moved slightly, when detecting the anglec of rotation of electrical motor 5 with coder 7, at first carry out direct motor drive control, car 1 is returned move to the mobile slightly position before of beginning, in order to make car 1 keep quiescence, carry out direct motor drive control then, make electrical motor 5 produce the torque that stops rotation.
Have again, the invention provides a kind of control setup 9, this control setup 9 is parked in certain stop 12 at car 1, and for passenger up and down and under door 13 states of opening of car 1, because of mal car 1 beginning of magnet stopper 6 is moved slightly, then control and stop moving of car 1 by the torque of electrical motor 5, then when the door 13 of car 1 is closed, remove the torque control of electrical motor 5, at the total weight of car 1 during less than the total weight of counterweight 2, after making car 1 move to the hoistway topmost operation of elevator is stopped, otherwise after making car 1 move to the hoistway foot operation of elevator is stopped.
Have again, the present invention has circular device 16, this circular device 16 is parked under door 13 states of opening of certain stop 12 and car 1 at car 1, because of mal car 1 beginning of magnet stopper 6 is moved slightly, starting stops its torque control of mobile electrical motor 5 slightly, then utilize read out instrument or broadcaster or buzzer phone to circulate a notice of to the passenger in the car 1, allow them be withdrawn into stop 12 from car 1 in the stage that car 1 stops.
Figure 5 shows that the braking force of magnet stopper generation and the graph of a relation of car load capacity.
In Fig. 5, when solid line I represents that car 1 is parked in stop 12, the relation of the load capacity (% load) of braking force that magnet stopper 6 produces and car 1.At the load capacity of car 1 during less than 50% (M point), because the Heavy Weight of counterweight 2, therefore car 1 has been acted on the power of ascent direction, the brake-force balance of the descent direction of the power of this ascent direction and magnet stopper 6, then car 1 maintenance is static.The braking force of the descent direction of electromagnetic system power 6 is to be the situation of empty car at car 1 for maximum.Otherwise, car 1 be capable of carrying a load of 50% (M point) when above, car 1 has been acted on the power of descent direction, the brake-force balance of the ascent direction of the power of this descent direction and magnet stopper 6.
When counting near staffing with the passenger of car 1 below just in case abnormal situation takes place in magnet stopper 6 is the action that example illustrates present embodiment 1.
Make its braking force be in the value of Figure 54 solid line I when following because of magnet stopper 6 mals, car 1 beginning is moved to descent direction.At this moment, the traction sheave 4 of towing machine 8 (or electrical motor 5) has only rotated the angle by the amount of movement decision of car 1, and this rotation amount can detect with coder 7.
Although magnet stopper 6 is moving, but when detecting the rotation of traction sheave 4 with coder 7, the control setup of present embodiment 1 judges that mal has taken place magnet stopper 6, the torque control of starboard motor 5, according to load capacity, make it produce the such braking force of straight line (dotted line II), broken line (dotted line) III or broken line (long and short dash line) IV shown in Figure 5 (torque that electrical motor 5 produces).In order to judge the mal of magnet stopper 6, if not only utilize the rotation of coder 7, also use the output of car position sensor 11, then can improve the judgement precision.
Its result, magnet stopper 6 is as long as the braking force of the difference of generation straight line I and these lines II, III, IV just can make car 1 static maintenance.If the braking force that causes because of the mal of magnet stopper 6 descends the braking force that produces less than the motor torque control of present embodiment 1, then can blocked portion car 1 move.
What kind of value the torque value that motor torque control produces adopts, and can consider has various modes.
Detecting the stage that electrical motor 5 has slight rotation with coder 7, can judge that according to its hand of rotation rising still is the braking force deficiency of which direction of descending.In addition, if deduct the weight of counterweight 2, then owing to obtain the value of unbalance load, so can infer direction and size with quite high precision for static maintenance car 1 necessary braking force from the output valve of weighting apparatus 10.
Also can not use the output of coder 7, if, then can improve precision and redundancy also with the output of the car position sensor 11 of measuring the rise and fall position of car 1 in hoistway.
The torque value that adds to electrical motor 5 for the rotation that stops electrical motor 5 is the value according to the unbalance load of measuring with weighting apparatus 10, produces the method for the braking force that is equivalent to the unbalance load part like that with electrical motor 5 just like the straight line II of Fig. 5; As broken line III, when bearing load is in dead band between the B of an A and point, do not produce braking force, produce the method for braking forces in zone in addition according to unbalance load with electrical motor 5; Perhaps produce the method etc. of the braking force (C point) of positive and negative each certain value with electrical motor 5 with the zone beyond in the dead band as broken line IV.
Even when not having weighting apparatus 10, also can carry out computing according to the direction, size (amount of movement) and the moving velocity that move slightly with coder 7 detected cars 1, produce the such braking force of broken line IV of Fig. 5 with electrical motor 5.Certainly, and best with the method for the output of the output of weighting apparatus 10 and coder 7.
Figure 6 shows that the graph of a relation of the load capacity of braking force that magnet stopper produces and car.
When using electrical motor 5 generation braking forces, in order not make electrical motor 5 overloads, utilize the limiting means 906 of control setup 9 to be limited, the feasible braking force that produces as shown in Figure 6 is not in more than the P or puts below the Q.
When utilizing the motor torque of present embodiment to be controlled to confirm car 1 to be in a safe door start-stop to end state, also can under the control of the circular control part 910 of control setup 9, utilize circular device 16, notify the passenger to withdraw from from car 1 in advance.
Control in the torque that utilizes electrical motor 5 and to stop after car 1 moves, if confirming the door 13 of car 1 closes, then for the mal of magnet stopper 6 is handled, even remove the torque control of electrical motor 5, car 1 is moved to till the perch of car 1, and this point is very important.Then, should make elevator out of service certainly.
Present embodiment does not just possess this function when the power supply of control setup 9 has a power failure.For fear of this situation, control setup 9 has the battery 909 of prevention power down, takes measures to make it also to have this function when having a power failure.
Industrial applicability
The apparatus for controlling elevator that the present invention is relevant, as mentioned above, owing to being parked in certain stop at car and being Passenger up and down and under the state that car door is opened, although electromagnetic brake moves because certain Undesired and make the static confining force deficiency of electromagnetic brake, car begins slight movement, detects with encoder When going out the anglec of rotation of motor, then utilize control device to drive control aforementioned electric motivation, it is produced stop The torque of aforementioned electric motivation rotation, the effect that therefore has are to produce even can access a kind of electromagnetic brake Give birth to the hypodynamic undesired aforementioned electric motivation of still utilizing of braking and strengthen brake force, do not make the passenger adventurous Apparatus for controlling elevator.
