Below, with reference to accompanying drawing, one embodiment of the present of invention are described.Fig. 1 is the block scheme of one embodiment of the invention, 2,4,7,13～15th, and with the described identical device of preamble.In addition, not shown structure is same as shown in Figure 6.
Among the microcomputer 16A only CPU21 and ROM22(referring to Fig. 6) content be different from before, it comprises operation controller 27 and the slip detection device 28 that is made of CPU21 and ROM22.
Operation controller 27 is according to running velocity V and floor detecting signal Zs, produces torque command Ts, braking instruction Bs, the instruction Dos and the instruction Dcs that closes the door open the door.Slip detection device 28 produces slip detecting signal S according to running velocity V, torque command Ts and braking instruction Bs.
Fig. 2 is ladder diagram, shows the program function of microcomputer 16A with relay circuit.
31～35th, relay coil, energising when various signals and instruction generation.The 31st, be used to produce the relay coil of slip detection signal S, the 32nd, be used to produce close the door the instruction Dcs relay coil, relay coil 33 is used for producing the instruction Dos that opens the door, the 34th, produce the relay coil that makes car 1 move to the top operating instruction Ct of uppermost storey, the 35th, generation makes car 1 move to the relay coil of the lowermost layer operating instruction Cb of lowest floor.
Vr is that the absolute value of running velocity V (for example exceeds datum velocity, the 5m/ branch) the sliding velocity signal that is generated the time, Ns is the normal door control order, produce according to common door switch control sequence and operated key, corresponding to the instruction Dos that closes the door, Vu is that running velocity V is the rising signals that timing generates, the Vd dropping signal that to be running velocity V generate when negative.
Be used to slide be connected in series on the relay coil 31 that detects under a contact VO closed under the sliding velocity signal Vr, the braking instruction Bs that produces in the brake switch power down closed b contact BB, when torque command Ts is terminated the positive delay timer T of b contact R E, T closure second after of closure.
The closed a contact NC that has been connected in series on the relay coil 32 that is used to close the door under normal door control order Ns, closed a contact SD under slip detection signal S has been connected in parallel on the NC of a contact.
Be connected in series with on the relay coil 33 that is used to open the door a contact DZ closed under the floor detecting signal Zs, when the instruction Dcs that closes the door stops the b contact DC of closure.
Be connected in series on the used relay coil 34 of top operation a contact VP closed under the rising signals Vu, a contact SD closed under the slip detecting signal S, when lowermost layer operating instruction Cb stops the b contact BT2 of closure.
In addition, be parallel with a contact TP1 closed under top operating instruction Ct on the circuit series that constitutes by a contact VP and SD.
Be in series with on the used relay coil 35 of lowermost layer operation a contact VM closed under the dropping signal Vd, a contact SD closed under the slip detecting signal S, when top operating instruction Ct stops the b contact TP2 of closure.
In addition, be parallel with a contact BT1 closed under lowermost layer operating instruction Cb on the circuit series that constitutes by a contact VM and SD.
Below, with reference to Fig. 1,2 and 6, the action of one embodiment of the invention is described.
As before, when car 1 moves under the control of operation controller 27, when arriving destination 3, open the door and distinguish detector 4 generation floor detecting signal Zs, input microcomputer 16A.
Operation controller 27 among the microcomputer 16A judges that by this car 1 stops, and cuts off the torque command Ts that gives power-converting device 15, and simultaneously, the output braking instruction Bs give magnet stopper 14.
In addition, when car 1 stopped, promptly torque command Ts interrupted, and when braking instruction Bs output was arranged, slip detection device 28 detected running velocity V.
At this moment, if running velocity V is about 0, can think that then magnet stopper 14 actions are normal, thereby slip detection device 28 does not produce the slip detecting signal, discharges a contact SD.
At this, in order to change under the door opening state, a contact NC discharges because of normal door control signal Ns, relay coil 32 power down, and the instruction Dcs that closes the door interrupts, and is connected a contact DC closure on the relay coil 33.
At this moment, car 1 is in the district of opening the door, and a contact DZ is closed because of floor detecting signal Zs, therefore, relay coil 33 power down, operation controller 27 produces the instruction Dos that opens the door.Thereby the door of car 1 is normally opened, the passenger in the car 1 and the person of waiting of the waiting space car of can freely coming in and going out.
Subsequently, when a contact NC after closure under the normal door control signal Ns that the operation because of the key of closing the door etc. produces, relay coil 32 power down once more produces the instruction Dcs that closes the door, door is closed, then, 3 operations of the downward floor of car 1 beginning.
On the other hand, when car stopped, if detect running velocity V above datum velocity, then a contact VO was closed because of sliding velocity signal Vr, and therefore, relay coil 31 is switched at T second (for example, 4 seconds) afterwards by positive delay timer T.
Thereby slip detection device 28 produces slip detecting signal S, and input operation controller 27 is connected a contact SD closure on each relay coil 32,34 and 35.
Like this, relay coil 32 energisings produce the instruction Dcs that closes the door, and b contact DC continues closed.Therefore, relay coil 33 power down under the situation that slip detecting signal S continues, can not produce the instruction Dos that opens the door.
In addition, slipping motion judges that be that the caused slip flase drop that rocks of the car 1 that causes in order to prevent to reach the passenger to come in and go out car goes out the delay time of used datum velocity and positive delay timer T car promptly stops after.
In addition, microcomputer 16A is to the calculation process that relates to each relay coil 31～33 order according to coil 31 to 33, with for example 50 milliseconds be the cycle, carry out repeatedly.
If, thereby can not keep car to stop, in this case,, just produce the instruction Dcs that closes the door as long as detect following full terms owing to the fault of magnet stopper 14 reduces lock torque.
(1) the torque command Ts of power-converting device 15 is interrupted;
(2) car 1 is in halted state, the brake switch power down;
(3) car 1 rises or descends with the speed that exceeds datum velocity.
On the other hand, relay coil 34 and 35 is under the initial condition, not energising, and therefore, a contact TP1 and BT1 discharge, b contact BT2 and TP2 closure.
Because the fault of magnet stopper 14 has slip detecting signal S to produce, a contact SD closure in the case, if the slipping motion of car 1 is an ascent direction, then by the energising of relay coil 34, produces top operating instruction Ct; If descent direction then by the energising of relay coil 35, produces lowermost layer operating instruction Cb.
For example, towards rising direction slipping motion, then a contact VP is closed because of rising signals Vu as if car 1, and relay coil 34 energisings produce top operating instruction Ct.
Thereby operation controller 27 makes the brake switch energising, cuts off braking instruction Bs, simultaneously, produces torque command Ts, and under common running control, it is top that cage operation is arrived.Thereby bob-weight 10 is docked with energy disperser 12, keep car 1 to stop, then, remove torque command Ts.
In addition, when producing top operating instruction Ct, a contact TP1 closure, the "on" position self-insurance of relay coil 34, simultaneously, b contact TP2 discharges, and relay coil 35 keeps power-down state.
On the contrary, if car 1 towards decline direction slipping motion, then a contact VM is closed because of dropping signal Vd, relay coil 35 energisings, thereby produce lowermost layer operating instruction Cb.Therefore, the relay coil oneself keeps "on" position, and relay coil 34 keeps power-down state, and simultaneously, car 1 moves to lowermost layer, by energy disperser 11, keeps stopping.
Embodiment 2
In addition, in the above-described embodiments, after the situation that the running velocity V of the slipping motion of car 1 exceeds datum velocity is detected, a contact VO closure, through after the delay time T, relay coil 31 energisings produce slip detecting signal S.But, also can set the comparison rank of multistage running velocity V, when surpassing the NG(fault) and during the datum velocity of level, produce slip detecting signal S immediately.
Fig. 3 is ladder diagram, and another can generate the processing action of microcomputer 16B of the embodiment of slip detecting signal rapidly to show the present invention with relay circuit.Among Fig. 3, Vn be exceed the NG level as running velocity V datum velocity (for example, the 20m/ branch) the NG speed signal that is produced the time, Vp be running velocity V under the NG level and PD(uncertain) level datum velocity (for example, 0.6m/ divide) the PD speed signal that generates when above, Vk is the OK speed signal of running velocity V generation under the datum velocity of PD level the time.
In this example, do not connect positive delay timer T(on the relay coil 31 referring to Fig. 2), and connected a contact NG closed under NG speed signal Vn, replace a contact VO.When running velocity V exceeded the NG level, a contact NG was closed because of the NG speed signal.Thereby when car stopped, if a contact NG is closed because of NG speed signal Vn, then relay coil 31 was switched on immediately, produced slip detecting signal S.
In addition, connect a circuit series on the relay coil 32, this circuit is made of a contact PD closed under PD speed signal Vp and b contact BB and RE, and this circuit series is in parallel with a contact NC.When running velocity V under the NG level and on the PD level time, a contact PD is closed because of the PD speed signal.Thereby when car stopped, if a contact PD is because PD speed signal Vp and closure, then relay coil 32 switch on immediately, and generation is closed the door and instructed Dcs.
In addition, be in series with a contact OK closed under OK speed signal Vk on the relay coil 33.When running velocity V was under the OK level, a contact OK was closed because of OK speed signal Vk.Thereby when car 1 is in the district of opening the door, and when the instruction Dcs that closes the door was cut off, if a contact OK is closed because of OK speed signal Vk, then relay coil 33 energisings produced the instruction Dos that opens the door.
Fig. 4 is an instruction diagram, and its hatched example areas and white space are illustrated in slide each speed signal Vn, the Vp that use in detecting and the generation zone NG of Vk, and PD and OK, transverse axis are time t, and the longitudinal axis is running velocity V.
Can be clear that from figure NG speed signal Vn produces when running velocity V divides when above at 20m/, PD speed signal Vp produces when running velocity V is on 0.6m/ divides under 20m/ divides, and OK speed signal Vk is when running velocity V generation when the 0.6m/ branch is following.
In addition, it is unusual to carry out a NG(every the execution cycle (50ms) of a CPU21) or OK(normal) judgement, uncertain at PD() time, judged result remains to next execution cycle.
NG speed signal Vn and running velocity V are irrelevant, produce when time t surpasses 1.2 seconds.
In this case, the absolute value of running velocity V is if be in the NG district, and then a contact NG is closed because of NG speed signal Vn, by relay coil 31, produce slip detecting signal S immediately, therefore, as before, car 1 moves to top or lowermost layer under door closure state.
In addition, if the absolute value of running velocity V is in the OK district, then a contact OK is closed because of OK speed signal Vk, by relay coil 33, produces the instruction Dos that opens the door, and therefore, the door of car 1 is opened, and the passenger is as passing in and out car usually.
When the judgement state continuance 1.2s in PD zone is above, then enter the NG zone, slip detecting signal S produces because of NG speed signal Vn.
Thereby magnet stopper 14 is as et out of order, even acceleration/accel a is less, and along with the past of time t, the running velocity V(=at that the slippage of car 1 operation causes) also can enter the NG zone, thus can correctly detect abnormal condition.
Embodiment 3
In the above-described embodiments, when running velocity V exceeds the datum velocity of NG level, produce slip detecting signal S, still, the device of the amount of movement X that detects car 1 can be set also, replace running velocity V as the slip judgment standard with the operation amount of movement.
Fig. 5 is an instruction diagram, and expression generates regional NG based on each speed signal of operation amount of movement X, and PD and OK, transverse axis are time t, and the longitudinal axis is operation amount of movement X.
Among the figure obviously, when operation amount of movement X is on 36mm, produce NG speed signal Vn, when operation amount of movement X below 36mm, 10(t-0.05) produce PD speed signal Vp when above, operation amount of movement X is at 10(t-0.05) generation OK speed signal when following.
Here, set for can compensate because of car 1 as the function of the judgment standard in OK zone and rock the error that causes.
X＝10（t-0.05）
Identical therewith, the judgment standard in NG zone also can be uncertain is 36mm, sets with function.
Usually, rocking when car 1 stops because be oscillating movement, so, from running velocity, be can be detected, still, X is very little for its operation amount of movement, thereby can not detect.
So, in this example,, perhaps there is the passenger to jump even car 1 rocks when stopping, can not detect slipping motion mistakenly yet.
Embodiment 4
If, be used as the slip judgment standard with running velocity V and both combinations of operation amount of movement X, flase drop can not take place just fully, significantly improve accuracy of detection.
For example, can be "+1 " also with the OK zone, the PD zone is " 0 ", the NG zone is " 1 ", logic operation goes out the judged result based on running velocity V and operation amount of movement X, with this as final judged result.
That is, regard 50 milliseconds of pressures of initial execution cycle as zone into P, make a contact PD(referring to Fig. 3) closure, the access door closed condition.
Then, judging that according to running velocity V each regional NG, PD and OK(are referring to Fig. 4) afterwards, X judges that each regional NG, PD and OK(are referring to Fig. 5 according to the operation amount of movement), each judged result is done the logical addition computing, thereby the generation net result is as shown in table 1.
Table 1
Judge by X judgement net result by V
OK OK→ OK
OK PD→ OK
OK NG→ PD
PD OK→ OK
PD PD→ PD
PD NG→ NG
NG OK→ PD
NG PD→ NG
NG NG→ NG
According to table 1, net result is under the situation of OK, judges that magnet stopper 14 is normal, finishes to check that car 1 enters door opening state.In addition, if net result is PD,, as be NG then every 50 milliseconds of computings that repeat once table 1, then be judged to be unusually, finish inspection.
In addition, after 1.2 seconds, as net result or PD, NG(is unusual then being judged to be), finish to check.
Running velocity V and operation amount of movement X are negative, and opposite with the service direction of car 1, in this case, net result is OK.
Like this, running velocity V and operation amount of movement X being combined when judging,, do not exist error detection to go out the possibility of slipping motion fully even big rocking takes place car 1 yet.
For example, take place to rock the amplitude maximum point of vibration under the big situation of rocking the limit operation on car 1 limit, operation amount of movement X becomes big, and running velocity V diminishes, and is 0 amplitude midpoint rocking, and it is big that running velocity becomes, and the operation amount of movement diminishes.Thereby, if these situations are carried out comprehensive logic determines like that by table 1, just can correctly, promptly judge the fault of magnet stopper 14.
In above-mentioned each embodiment, be that example is described with general wirerope formula elevator, still, the present invention certainly, also has same effect and effect also applicable to elevator of winding drum type or hydraulic pressure elevator.
For example, in hydraulic pressure elevator, when car arrived at floor, valve can not fail, in this case, car 1 while opening the door to the whereabouts.If employing the present invention can prevent that equally also the passenger from fatal accident taking place in possible trouble.
