Description

Elevator operating control device
Technical field
The present invention relates to a kind of elevator operating control device, realize that safety and the elevator of elevator user when improving earthquake takes place effectively moves.
Background technology
In recent years, the office building of business and government office is to the skyscraper development, and the skyscraperization of individual dwelling house such as apartment is also being promoted.Concerning the people who in such skyscraper, works and live, use the chance of elevator to increase.And the common people beyond the people who works in skyscraper and live use the chance of elevator also to increase in median low structure.
In the state that buildings such as earthquake generation and high building are waving, because it is dangerous starting elevator and cab is moved, therefore, for example in the hoist trunk of elevator or Machine Room, seismograph (P ripple detector, S ripple detector) is set, during vibrations more than seismograph detects predefined certain intensity, stop elevator.Under this situation, when earthquake takes place elevator cage be in service, when at once elevator being stopped, elevator cage be positioned at layer with layer the situation of centre under, the user may be closed in the cab.
For with the anti-possible trouble that terminates in of the generation of this state of affairs, during vibrations more than detecting predefined certain intensity, operating elevator cage is stopped, and move it the nearest floor of distance current location and it is stopped.Under this state, open the door of cab and the door of boarding place (elevator hall) of this floor, with automatic sound or show and point out the user in the cab outside cab, to hide, afterwards, close and make elevator be transformed into halted state.Therefore, cab becomes the state that stops at this floor.This when earthquake takes place the operation of elevator be commonly referred to as " during earthquake control operation ".
And, the monitoring terminal that monitors this elevator operation is installed in the elevator that majority use, will monitor the central monitoring position of result notification by communication line to elevator maintenance management company.Specifically, when causing the elevator malfunction owing to reasons such as fault or power failures, when becoming error state, detecting this error state and signal will take place unusually and notify from the trend central monitoring position by communication line.
When the unusual generation signal that shows on the telltale from monitoring terminal, the surveillant of central monitoring position (operator) investigates the error state of this elevator by monitoring terminal, under the situation that needs maintenance person checks, sends maintenance person to go to on-the-spot elevator.Maintenance person carries out the repairing and the inspection of this elevator, makes elevator return to original mode of operation.
Yet, in the earthquake countermeasure when above-mentioned earthquake takes place, also have the following problem that should solve.
As mentioned above, when the earthquake more than the certain scale took place, each elevator that is provided with in each building in the generation area that is present in this earthquake detected earthquake simultaneously, and implemented aforesaid " during earthquake control operation ".In this case, when central monitoring position at synchronization by communication line from all elevators of oneself administration when receiving identical earthquake generation detection signal, because central monitoring position bonded assembly connection way simultaneously is limited, so central monitoring position is difficult to receive the seismic monitoring signal from each elevator.
And, be difficult to determine the elevator that essence is damaged takes place because of earthquake.That is to say that because the elevator quantity of control operation is very many when carrying out earthquake, maintenance person that therefore must the certain number of expensive time cause carries out itinerant mission to the whole elevators in the earthquake generation area.
In addition, the elevator of control operation is not impaired because of earthquake when having carried out this earthquake, and the situation that can return to common operation when earthquake behind the control end of run at once is more.So, as central monitoring position, need to the elevator of substantive damage might take place, than can be assumed to " control operation during earthquake " normal termination general most of elevators preferentially send maintenance person.
Summary of the invention
The present invention In view of the foregoing carries out, and purpose provides a kind of elevator operating control device, when earthquake takes place, can define at central monitoring position the elevator of substantive damage may take place because of earthquake, and can preferentially take necessary countermeasure to this elevator.
In order to solve above-mentioned problem, elevator operating control device of the present invention has: monitoring terminal monitors the running state of elevator and notifies to central monitoring position by communication line; P ripple detector detects the P ripple that reaches elevator when earthquake takes place; S ripple detector detects the S ripple that reaches elevator when earthquake takes place; The unit is carried out in control operation during earthquake, control operation when carrying out earthquake when above-mentioned P ripple detector detects P ripple more than the specified level; The pressure unit of transmitting messages is only detecting P ripple more than certain level through specified time from above-mentioned P ripple detector, when S ripple detector does not detect S ripple more than certain level yet, give central monitoring position by monitoring terminal with the earthquake detection signalisation.
Can think that elevator damages because of the substance that earthquake causes, most cases occurs in the later S ripple (principal earthquake) of P ripple (prelinaries).Therefore, after detecting the P ripple by P ripple detector, can't correctly detect at S ripple detector under the situation of the S ripple more than certain level, substantive damage might take place in this elevator.For example, S ripple detector situation that fault taken place just belongs to such situation.
Therefore, elevator operating control device of the present invention is only after detecting the P ripple and normally do not detect under the situation of S ripple the earthquake detection signal is sent to central monitoring position.
And in other invention, S ripple detector is arranged in the pit (pit) of elevator lifting channel, and P ripple detector is arranged in the Machine Room of elevator lifting channel top.
And, in other invention, have elevator forced stop element, when detecting S ripple more than certain level, S ripple detector make elevator be transformed into halted state.
The present invention can define the elevator that may take place by seimic substantive damage from the numerous elevator that meets with earthquake, and preferentially this elevator is taked necessary countermeasure.

And, if the elapsed time T of timekeeping circuit 33 PReach specified time Tmax (Q1), then earthquake detection signal g is sent (Q5) to central monitoring position 6, and remove the elapsed time T of timekeeping circuit 33 P(Q6).
Fig. 6 for expression when S ripple detector 4b normally exports the state of S ripple detection signal e of H level, the sequential chart of the action of the control device for running the engine of the elevator of embodiment.
When at moment T 1, P ripple judging part 31 detects specified level L PAbove P ripple and when exporting the P ripple detection signal b of H level, timekeeping circuit 33 beginning elapsed time T PTiming c.Simultaneously, control operation f during the 35 beginning earthquakes of control operation implementation portion during earthquake.Begin to have passed through time T as control from earthquake time operation f 1Moment t 2, control operation f finishes during earthquake, afterwards, and at elapsed time T PDo not reach the moment t of specified time Tmax 3, S ripple judging part 32 detects certain level L SAbove S ripple, and during the S ripple detection signal e of output H level, the elapsed time T of timekeeping circuit 33 PBe eliminated elapsed time T PTiming c stop.And elevator 2 becomes operation halted state h.
In addition, as the output time t of the S of H level ripple detection signal e 3In the scope of Tmax, become the t finish time of control operation f when earthquake at the appointed time 2In the time of later on, control operation f finishes during earthquake, and elevator 2 become operation halted state h, therefore, there is no need to make once more elevator 2 to become run-stopping status h.
As mentioned above, when this situation of the earthquake more than the certain scale has taken place in 9 pairs of areas in central monitoring position 6 administrations of oneself of operator of central monitoring position 6, when confirming, even if also send maintenance person 12 for the corresponding elevator of seismic monitoring signal unconfirmed from the information of various reports and Bureau of Weather Reports.12 couples of maintenance persons are at moment t 4Elevator 2 during operation stops is checked i, if no abnormal, then at moment t 5Reset the P ripple detection signal b and the S ripple detection signal e of P ripple judging part 31 and S ripple judging part 32, and reset elevator 2.
Fig. 7 is a sequential chart, is illustrated in for example S ripple detector 4b et out of order, can't be when this S ripple detector 4b normally exports the state of S ripple detection signal e of H level, the action of the elevator operating control device of embodiment.
When at moment t 1, P ripple judging part 31 detects specified level L PAbove P ripple, and during the P ripple detection signal b of output H level, timekeeping circuit 33 beginning elapsed time T PTiming c.Simultaneously, control operation f during the 35 beginning earthquakes of control operation implementation portion during earthquake.Control operation f's begins to have passed through time T from earthquake the time 1Moment t 2, control operation f finishes during earthquake, afterwards, and at moment t 6Elevator 2 becomes operation halted state h.
Even at moment t 1, timekeeping circuit 33 beginning elapsed time T PTiming c, and at elapsed time T PDo not reach the moment t of specified time Tmax 3, produced certain level L among the seismic shock a SAbove S ripple is also to be not cause by this seimic infringement, fault etc., from the S ripple detection signal e of S ripple judging part 32 output H level.
And, at elapsed time T PReached the moment t of specified time Tmax 7, time limited signal d is sent to earthquake detection signal transmission unit 37 from timekeeping circuit 33, the elapsed time T of timekeeping circuit 33 PBe eliminated, and stop elapsed time T PTiming c.At moment t 1, earthquake detection signal g is notified to central monitoring position 6.
When the operator 9 of the central monitoring position 6 earthquake detection signal g of elevator 2 that confirmed appointment that telltale 14 is shown, operating operation portion 15 also passes through mobile communication circuit 10 or internet 11, the portable phone 13 that the maintenance person 12 of maintenance management company is held sends indication, indicates it to go to earthquake detection signal g to send the elevator 2 in source and preferentially elevator 2 is checked.
