Description

  The present invention relates to a restoration diagnosis operation device at the time of an earthquake, and particularly relates to an operation technique at the time of a restoration diagnosis operation that copes with earthquakes that occur continuously.

  Conventionally, in order to restore an elevator that has been suspended due to seismic control operation, an operator performs a low-speed maintenance operation on the elevator at the site, confirms whether there is any abnormality, and determines whether the restoration is possible. It was.

However, since it takes time to restore the elevator, a program for performing the recovery diagnosis operation remotely via a communication line or a program for the recovery diagnosis operation stored in the control device of the elevator is stored. An apparatus that starts and automatically performs a recovery diagnosis operation has been proposed as a conventional technique.

Further, for example, Patent Document 1 discloses a technique for recovering an elevator more safely in response to an aftershock so that an earthquake can be detected by returning a seismometer that has once operated in an elevator in a dormant state after the occurrence of an earthquake. Proposed. According to this Patent Document 1, after the earthquake detector is put into the earthquake detection state again after a short period of time, the count value of the timer means is reset by another earthquake and the recovery operation can be performed when the count value reaches a predetermined value. It is disclosed that a recovery operation is performed in a state.

JP-A 61-64683

Generally speaking, an earthquake called an aftershock may occur within a short period of time after the occurrence of the earthquake, and the elevator stops due to the first earthquake, and during the earthquake recovery diagnosis operation is being carried out for recovery. If an aftershock occurs, the elevator equipment may be damaged depending on the size of the aftershock.

The technique disclosed in Patent Document 1 takes into account aftershocks and considers the start timing of recovery operation using timer means. However, there is a viewpoint for damage to elevator equipment due to recovery operation during recovery diagnosis operation. There is a problem that it is not fully considered.

  The present invention has been made in consideration of the above problems, and when an aftershock is detected before the start of earthquake recovery diagnosis operation, the traveling speed and door opening / closing speed of the earthquake recovery diagnosis operation are set to be lower, An object of the present invention is to provide an earthquake recovery operation device that reduces damage to equipment caused by an earthquake.

In order to solve the above problems, the present invention mainly adopts the following configuration.
Based on the first vibration detection signal detected by the seismic detector installed in the elevator, the earthquake control operation is performed to stop the car at the nearest floor, and the stop of the car due to the seismic control operation is canceled and the elevator An earthquake recovery diagnosis operation device that performs an earthquake recovery diagnosis operation, wherein after a predetermined time has elapsed since the detection of the first vibration detection signal, the car travels at a lower speed than during normal operation and the door opens and closes normally. When the elevator restoration diagnosis operation is performed as the door opening / closing speed at the time, and the second vibration detection signal of the seismic detector is detected before the predetermined time has elapsed since the detection of the first vibration detection signal, Elevator restoration diagnosis with ultra-low speed running that is even slower than the low-speed running and door opening and closing speed that is even slower than the door opening and closing speed during normal operation A structure to carry out the transfer.

  According to the present invention, when the next earthquake is detected within a predetermined time from the occurrence of the first earthquake, the traveling speed and door opening / closing speed of the restoration operation at the time of earthquake are controlled to be lower than those in the normal restoration diagnosis operation. By performing earthquake recovery diagnosis operation, it is possible to prevent equipment damage due to consecutive earthquakes (for example, prevention of car derailing, mitigation of contact impact between car door and landing door). .

It is a flowchart which shows the procedure of the operation | movement in the restoration recovery operation device at the time of an earthquake which concerns on this embodiment.

An earthquake recovery diagnosis operation apparatus according to an embodiment of the present invention will be described in detail below with reference to FIGS. 1 and 2. 1 and 2 are drawings showing the contents as described in the brief description column of the above-mentioned drawings.

In the drawing, 1 is a car, 2 is a door, 3 is a door control device, 4 is an earthquake detector, 5 is high gull detection means, 6 is low gull detection means, 7 is low gull return means, and 8 is extra low gull detection. , 9 is a special low gull return means, 10 is a control device, 20 is an earthquake recovery diagnosis operation device, 21 is a processing device, 22 is the nearest floor stop means, 23 is a low gull release means, and 24 is a special low gull release means. , 25 represents recovery diagnosis operation low speed setting means, and 26 represents recovery diagnosis operation traveling means.

In FIG. 1, the overall configuration of the elevator mainly includes a car 1, an earthquake detector 4, a control device 10, and an earthquake recovery diagnosis operation device 20 according to the present embodiment. An elevator car 1 on which a passenger gets into a designated floor is provided with a door 2 that opens and closes the doorway of the car 1 and a door control device 3 that controls the opening and closing operation of the door 2.

The control device 10 is arranged at a position separated from the car 1, and according to a hall call (not shown) or a car call (not shown) used by the passenger, the car 1 travels to the floor desired by the passenger and arrives. Sometimes it has a function of opening / closing the door 2 by outputting an opening / closing signal to the door control device 3.

The earthquake detector 4 is installed in an elevator machine room or pit, and outputs a vibration detection signal to the control device 10 when vibration of a predetermined seismic intensity (gal) or more is detected.

  The earthquake detector 4 is capable of detecting three-stage vibration, and operates when detecting a high-gal earthquake vibration (for example, 100 gal) that is predicted to be difficult to restore the elevator. 5 and a low-gull detection means 6 (for example, 60 gull) that operates when a vibration of a low-gull earthquake that is expected to be able to restore the elevator is detected. And an extra low gall detecting means 8 (for example, 2.5 gall) that operates when fine movement is detected.

  The earthquake detector 4 further has a low-gull return means 7 and an extra-low-gull return means 9, which return means 7, 9 will be described later from an earthquake recovery diagnosis operation device 20 according to this embodiment. The low-gull detection means 6 and the extra-low-gull detection means 8 are made effective by the release signal.

  As shown in FIG. 1, the control device 10 is connected to each of the components 3, 4, and 20 outside the control device 10, and generally controls the operation of the elevator. The vibration detection signals detected by the low-gull detection means 6 and the extra-low-gull detection means 8 are input, and the input vibration detection signals are output to the earthquake recovery diagnosis operation device 20.

The earthquake recovery recovery operation device 20 according to the present embodiment includes a processing device 21, a nearest floor stop unit 22, a low gull release unit 23, an extra low gull release unit 24, a recovery diagnosis operation low speed setting unit 25, and a recovery diagnosis operation travel unit. 26.

  When the processing device 21 of the earthquake recovery operation device 20 receives the vibration detection signal from the control device 10 from the earthquake detector 4 (at least the vibration detection signals from the high gull detection means 5 and the low gull detection means 6). Then, the nearest floor stop means 22 is activated to output a nearest floor stop signal to the control device 10. When the nearest floor stop signal is input from the earthquake recovery diagnosis operation device 20, the control device 10 stops the car 1 to the nearest floor, opens the door 2 once, closes it after a predetermined time, and puts it into a resting state.

  Here, when the high-gull detection signal from the high-gull detection means 5 is input, the elevator is in a suspended state as described above, but it is determined that there is no visual abnormality after carrying out equipment inspection by a maintenance worker. In this case, the seismic detector 4 stops the output of the high-gull detection signal by manually releasing the high-gull detection means 5 by the maintenance worker (resetting the vibration detection signal output from the high-gull detection means 5). To stop the signal).

  When the output of the high-gull detection signal is stopped, the processing device 21 stops the nearest floor stop means 22 and stops outputting the nearest floor stop signal to the control device 10, and the control device 10 stops the elevator. To enable normal operation.

  When the low-gull detection signal from the low-gull detection means 6 is input to the earthquake recovery diagnosis operation device 20 according to the present embodiment via the control device 10, the processing device 21 operates the nearest floor stop means 22 to operate. The nearest floor stop signal is output to the control device 10, and the control device 10 stops the car 1 at the nearest floor and puts it into the resting state in the same manner as the input of the high-gull detection signal.

  At that time, the processing device 21 activates the extra low gull release means 24 and outputs an extra low gull release signal to the control device 10 in order to confirm the occurrence of the earthquake again. The control device 10 to which the extra low gull release signal is input outputs the extra low gull release signal to the earthquake detector 4. The earthquake detector 4 to which the extra low gull release signal is input activates the extra low gull return means 9 and enables the extra low gull detection means 8 to detect the extra low gull detection signal.

In other words, when the low-gull detection signal is detected by the low-gull detection means 6, the special-low-gull detection signal by the special-low-gull detection means 8 is output continuously. The detection means 8 is returned to a state where vibration can be detected, so that the presence or absence of an aftershock can be confirmed.

  If the special low-gull detection signal is not detected by the special low-gull detection means 8 within a predetermined time after processing of the nearest floor stop of the car 1, the processing device 21 controls the control device for the nearest floor stop signal after the predetermined time has elapsed. 10 is stopped, the recovery diagnosis operation traveling means 26 is activated, and a recovery diagnosis operation traveling signal is output to the control device 10. The control device 10 to which the recovery diagnosis driving travel signal is input performs the recovery diagnosis operation.

  Here, the restoration diagnosis operation is performed by the control device 10 based on the restoration diagnosis operation traveling signal, the traveling speed is set to a low speed operation performed in a maintenance operation or the like, and the door opening / closing speed is a normal operation during passenger use. Normal opening / closing speed is set.

  The car 1 that has been put into a dormant state on the nearest floor when the low-gull detection signal from the low-gull detection means 6 is input is moved to the lowest floor at a low speed by performing a recovery diagnosis operation using a recovery diagnosis operation running signal after a predetermined time has elapsed. And then reciprocate at low speed to the top floor. When there is no equipment abnormality that causes a failure during this low-speed driving (when no abnormal signals are detected from various sensors provided at each part), the car runs to the top floor at normal high-speed driving speed during normal operation. At this time, the doors of each floor are opened and closed at the normal opening and closing speed when each floor is stopped. After arriving at the top floor, drive to the bottom floor at normal high speed.

  During this time, if no device abnormality that causes failure or the like via various sensors (not shown) is detected during traveling and when the door is opened and closed, the processing device 21 determines that the restoration diagnosis operation has ended normally, and cancels low-gull. The means 23 is activated to output a low gull release signal to the control device 10.

  The control device 10 to which the low gull release signal is input outputs the low gull release signal to the earthquake sensor 4. The earthquake detector 4 to which the low-gull release signal is input activates the low-gull return means 7 and releases the low-gull detection means 6. When the low-gull detection signal is not input to the processing device 21 due to the release of the low-gull detection means 6, the processing device 21 stops the low-gull release means 23, and outputs the recovery diagnostic driving travel signal to the recovery diagnostic driving travel signal 26. It stops, ends the recovery diagnosis operation, and the elevator becomes normal operation.

  If an abnormality occurs during the recovery diagnosis operation, the elevator stops on the spot and stays in a rest state until the maintenance worker is dispatched and restored.

  In addition, the special low-gull detection means 8 of the seismic detector 4 operates during the predetermined time when the low-gull detection signal is input to the processing device 21 and enters the dormant state on the nearest floor. When the signal is input to the earthquake recovery diagnosis operation device 20 via the control device 10 (for example, when there is an aftershock within a predetermined time from the rest state), the processing device 21 sets the recovery diagnosis operation low speed setting means 25. It starts and outputs a recovery diagnosis operation low speed setting signal to the control device 10.

  The control device 10 to which the restoration diagnosis operation low speed setting signal is input sets the traveling speed during the restoration diagnosis operation to a low speed (ultra low speed) that is much slower than the normal low speed, and sets the door opening / closing speed during the restoration diagnosis operation during the normal operation. Set to a slower opening / closing speed (low speed). Next, when a restoration diagnosis operation travel signal is input to the control device 10 after the predetermined time of the timer starts, for example, when the nearest floor stop processing is started, the control device 10 is set at a lower and slower travel speed that is set. Drive to the bottom floor and then reciprocate to the top floor.

  In the meantime, if there is no equipment abnormality that causes a failure or the like, the vehicle is then driven to the top floor by operation on each floor at a normal high speed traveling speed in normal operation. At this time, the doors on each floor are opened and closed at an opening / closing speed set slower than usual when each floor is stopped. After arriving at the top floor, a recovery diagnosis operation is performed in which the vehicle travels to the bottom floor at a normal high speed.

  Next, the operation at the time of earthquake occurrence in the earthquake recovery diagnosis operation device 20 according to the embodiment of the present invention will be described using the flowchart of FIG.

  First, when the elevator is operating normally, in step S <b> 1, the processing device 21 confirms whether or not a high-gull detection signal detected by the high-gull detection means 5 of the earthquake detector 4 is input via the control device 10. When there is an input of a high-gull detection signal (YES in S1), in step S21, the processing device 20 activates the nearest floor stop means 22, outputs the nearest floor stop signal to the control device 10, and ends the processing.

  When there is no input of the high-gull detection signal (NO in S1), in step S2, the processing device 21 determines whether the low-gull detection signal detected by the low-gull detection means 6 of the earthquake detector 4 is input via the control device 10 Confirm. If no low gull detection signal is input (NO in S2), normal operation is continued in step S22 and the process is terminated.

  When there is an input of a low-gull detection signal (YES in S2), in step S3, the nearest floor stop means 22 is activated, the nearest floor stop signal is output to the control device 10, and the car 1 is stopped on the nearest floor. Furthermore, in order to enable the extra low gull detection means 8 of the earthquake detector 4 (when the low gull detection signal is output, the extra low gull detection signal is also continuously output), the extra low gull release is performed. The means 24 is activated and an extra low gull release signal is output to the earthquake detector 4 via the control device 10. The earthquake detector 4 operates the extra low gull return means by the extra low gull release signal from the control device 10 to effectively operate the extra low gull detection means 8.

  Next, in step S4, a timer in the processing device 21 is activated in order to start measurement of a predetermined time after detection of low gull.

  In step S5, the presence or absence (for example, the presence or absence of an aftershock) of the extra low gull detection signal detected by the extra low gall detection means 8 that is effectively in operation by the earthquake detector 4 is confirmed. When there is an input of the extra low gull detection signal (YES in S5), the recovery diagnosis operation low speed setting means 25 is activated in step S23, the recovery diagnosis operation low speed setting signal is output to the control device 10, and step S3 is performed. Prepare for further extra low-gull detection. At this time, the control device 10 to which the restoration diagnosis operation low speed setting signal is input sets the traveling speed during the restoration diagnosis operation to a low speed (ultra low speed) that is much slower than the normal low speed, and sets the door opening / closing speed during the restoration diagnosis operation. Set the opening / closing speed (low speed) much slower than usual.

  If there is no special low-gull detection signal input (NO in S5), in step S6, it is confirmed whether or not a predetermined time has elapsed since the start of the timer. If the predetermined time has not elapsed (NO in step 6), step S5 is executed. Repeat.

  When the predetermined time has elapsed (YES in step 6), in step S7, the output of the nearest floor stop signal to the control device 10 is stopped, the recovery diagnosis operation travel means 26 is activated, and the recovery diagnosis operation travel signal is sent to the control device 10. Output.

Here, the control device 10 to which the recovery diagnosis driving travel signal is input performs the recovery diagnosis operation. The low-speed traveling speed and the door opening / closing speed at this time are the normal low-speed traveling speed and the normal door opening / closing speed in the recovery diagnosis operation unless the procedure S23 is set. If step S23 is set, as described above, the low-speed traveling speed (ultra-low speed) that is slower than normal and the door opening / closing speed (low speed) that is slower than normal (the processing device 21 stores the presence or absence of the setting of step S23). And run control based on this).

  Next, in step S8, if an abnormality occurs during the recovery diagnosis operation (YES in step 8), in step S24, the elevator stops on the spot and is put into a dormant state until the maintenance worker is dispatched and restored. The process ends.

  If no abnormality occurs during the recovery diagnosis operation (NO in step 8), the end of the recovery diagnosis operation is confirmed in step S9. If not completed (NO in step 9), step S8 is repeated.

When the restoration diagnosis operation is completed normally (YES in step 9), in step S10, the restoration diagnosis driving traveling signal output by the restoration diagnosis driving traveling unit 26 is stopped and the low gull releasing signal is output by the low gull releasing unit 23. However, the elevator becomes a normal operation and the elevator can be used.

  As described above, the present invention can detect the traveling speed and door opening / closing speed of the restoration operation during earthquake recovery when the next earthquake is detected within a predetermined time from the occurrence of the first earthquake even if earthquakes occur continuously. Carry out earthquake recovery diagnosis operation that is controlled at a lower speed than normal recovery diagnosis operation, for example, to detect and prevent the car from derailing in advance, or the impact of contact between the car door and the landing door It is possible to prevent equipment damage due to earthquakes that occur continuously by mitigating the above.
