Elevator equipment

The present invention relates to an elevator apparatus having a control operation function during an earthquake.

In Japan, where earthquakes occur frequently, elevator devices equipped with an earthquake-controlled operation function are widespread. In the elevator apparatus having the above function, an earthquake detector is provided in advance on the upper part of the building, etc., and in accordance with the operation state of this earthquake detector, for example, control operation such as stopping the elevator at the nearest floor is performed. Yes.

Conventional techniques relating to such a control operation during an earthquake are disclosed in, for example, Patent Documents 1 and 2 below.
Specifically, in Patent Document 1, when the seismic detector operates, the elevator car is immediately stopped at the nearest floor and the user is taken off from the car, and then the door is closed and the car is put on standby. Things have been proposed. Patent Document 2 proposes that when the car stops in an unopenable section due to an earthquake, the car is automatically driven to the openable position while monitoring the vibration generated in the car. Yes.

On the other hand, some elevator systems equipped with an earthquake control operation function have an express zone set in a part of the car's ascending / descending process, such as those installed in high-rise buildings. In such an elevator apparatus, when a relatively large earthquake occurs while the car is traveling in the express zone, the car stops in the express zone, and so-called confinement may occur.

In view of such circumstances, various proposals have conventionally been made for an earthquake operation control function of an elevator apparatus in which an express zone is set.
For example, as a conventional technique, when an elevator stops in an express zone due to an earthquake, a vehicle is switched to a low speed operation after a certain time and the car is driven to the nearest floor (see Patent Document 3). As another conventional technique, after the elevator stops due to an earthquake, the car is stopped while calculating the remaining distance to the nearest floor stop, and the car is stopped at the correct landing position ( For example, see Patent Document 4).

The elevator apparatus in the present embodiment is installed in a high-rise building or the like, and an express zone is set in a part of the lifting / lowering process of the car 1. The express zone refers to a section that includes only floors that are not serviced during normal operation and exist between upper and lower service floors (floor where the car 1 stops during normal operation of the elevator). For example, when the next service floor after the first floor is the 30th floor and the car 1 passes between the second floor and the 29th floor without stopping, the section including the floors from the second floor to the 29th floor is called an express zone.

In addition, in the express zone, an emergency landing entrance (not shown) is installed, for example, every 10th floor in consideration of the safety of users in the car 1 after the earthquake. This emergency landing doorway is an doorway used by a user to escape from the car 1 in an emergency. That is, the car 1 does not stop at the emergency landing doorway during normal operation of the elevator.

That is, a predetermined control operation is performed according to the operating state of the P-wave sensor 3 and the S-wave sensor 4.

Here, the P-wave detector 3 has a function of detecting an initial tremor (P-wave) of an earthquake. Then, the P wave detector 3 outputs predetermined earthquake information to the control device 2 by detecting an earthquake P wave.
The S wave detector 4 has a function of detecting the main motion (S wave) of the earthquake. The S wave detector 4 outputs predetermined earthquake information to the control device 2 by sensing the S wave of the earthquake. Specifically, the S wave detector 4 is configured to be able to detect the occurrence of an earthquake at a plurality of levels according to the acceleration generated in the building, and outputs earthquake information corresponding to the detected earthquake level. To do. In the present embodiment, the S-wave detector 4 is configured to output earthquake information corresponding to each of the accelerations of extra low gal, low gal, and high gal when detected.

On the other hand, the main part of the control device 2 is constituted by, for example, the operation control means 5, the in-car user detection means 6, the communication means 7, the earthquake information input means 8, and the seismic control operation means 9.
The operation control means 5 has a function of performing various operation controls of the elevator. For example, a normal operation in which the car 1 responds to a hall call or a car call is performed by the operation control means 5.

The car user detection means 6 has a function of detecting the presence or absence of a user in the car 1. The in-car user detecting means 6 is, for example, based on registration information of a car call or a hall call, load information in the car 1 detected by a scale device (not shown), and a camera (not shown) in the car 1. The presence / absence of a user in the car 1 is detected based on the captured image information, voice information from the interphone 1a, and the like. The in-car user detection means 6 may perform the detection using only one of the above information, or may perform the detection using a plurality of information. Further, the car user detection means 6 is not limited to the above-mentioned configuration, and uses a biometric authentication device that performs authentication by fingerprints or veins when using an elevator, or RFID (Radio Frequency Identification). Or an ID collation device such as a non-contact type IC card.

The communication means 7 has a function for communicating with the car 1. That is, the control device 2 transmits and receives signals to and from each device provided in the car 1 via the communication unit 7.
The earthquake information input means 8 has a function for inputting each earthquake information output from the P wave sensor 3 and the S wave sensor 4 into the control device 2.

The seismic control operation means 9 has a function of controlling a predetermined seismic control operation based on the level of the earthquake detected by the P-wave sensor 3 and the S-wave sensor 4. That is, the seismic control operation unit 9 controls the seismic control operation according to the level of the earthquake based on the earthquake information input to the earthquake information input unit 8.

Specifically, the seismic control operation means 9 includes each determination means shown in 10 to 13 and an operation control means 14 for appropriately controlling the operation of the elevator based on the determination results of these determination means 10 to 13. Is provided. The determination means 10 has a function for determining the operation state of each seismic detector, the determination means 11 has a function for determining the state relating to the car 1, and the determination means 12 has a time required for the car 1 to stop at a specific position. The determination means 13 has a function of determining a traveling start condition when the car 1 stops in the express zone due to the occurrence of a high level earthquake.
Below, based on FIG.2 and FIG.3, operation | movement of the control operation means 9 at the time of an earthquake which has the said structure is demonstrated concretely.

When an earthquake occurs in the vicinity of the elevator apparatus, the shaking (acceleration generated in the building) is detected by each earthquake detector, and the earthquake information is input to the earthquake information input means 8.
Therefore, the earthquake control operation means 9 of the control device 2 first determines the operation state of each earthquake detector based on the earthquake information input to the earthquake information input means 8. Specifically, in the seismic control operation means 9, the determination means 10 determines whether the P wave detector 3 has been operated, that is, whether the P wave detector 3 has detected an earthquake P wave (S 101). ). If there is no operation of the P-wave detector 3 in S101, the control device 2 continues the normal operation of the elevator.

When the P-wave sensor 3 is operating in S101, the determination means 10 next determines whether the special low level that is the minimum level of the S-wave sensor 4 has operated, that is, It is determined whether a level earthquake has been detected (S102). Note that if there is no extra low level operation of the S wave detector 4 in S102, the control device 2 continues the normal operation of the elevator.

When the special low level of the S wave sensor 4 is operating in S102, the determination means 10 next determines whether a low level that is one greater than the special low level of the S wave sensor 4 has operated, that is, S It is determined whether or not a low level earthquake is detected by the wave sensor 4 (S103). In addition, when it is operating only to the extra low level of the S wave sensor 4 (No in S103), the operation control means 14 causes the car 1 to run and stop on the nearest floor (stop floor in normal operation), and the elevator Is stopped (S104). Then, the control device 2 returns the elevator to the normal operation after a predetermined time has elapsed since the operation was stopped in S104 (S105).

When the low level of the S wave detector 4 is operating in S103, the earthquake control operation means 9 determines whether or not the car 1 is traveling in the express zone by the determination means 11 (S106). At this time, if the car 1 is not traveling in the express zone, the operation control means 14 causes the car 1 to travel and stop on the nearest floor (stop floor in normal operation), and stops the operation of the elevator (S107). Note that the suspension of operation in S107 is due to the fact that the S-wave detector 4 has detected a low level earthquake, so that the subsequent elevators are normally operated manually on condition that inspection by a professional engineer has been performed. Returning to operation (S108).

On the other hand, if the car 1 is traveling in the express zone in S106, the seismic control operation means 9 causes the determination means 12 to cause the car 1 to reach the nearest floor (stop floor in normal operation) within a predetermined reference time. It is determined whether or not it can be stopped (S109). If it is determined in S109 that landing within the reference time is possible, the process proceeds to S107 and the same operation as described above is performed.

If it is determined in S109 that landing within the reference time is impossible, the seismic control operation means 9 causes the determination means 10 to operate the high level which is the maximum level of the S-wave detector 4. That is, it is determined whether a high level earthquake is detected by the S wave detector 4 (S110). Note that even if it is determined in S109 that landing within the reference time is impossible, the operation control means 14 will perform S wave if the low level of the S wave sensor 4 is operating in S103. Run the car 1 towards the nearest floor until the high level of the sensor 4 is activated. When the car 1 reaches the nearest floor without the high level of the S wave sensor 4 being operated, the operation is suspended on the nearest floor (No in S110 to S107).

Even if the high level of the S wave detector 4 is operated while the car 1 is traveling in the express zone after the low level of the S wave detector 4 has been operated, the operation control means 14 determines the reference in S109. If it is determined that landing in time is possible, the process proceeds from S109 to S107 and the car 1 continues to travel. On the other hand, if it is determined in S109 that landing within the reference time is impossible, the operation control means 14 causes the car 1 to urgently stop in the express zone (S111).

When the car 1 stops in the express zone in S111, the seismic control operation means 9 determines the conditions for resuming the traveling of the car 1 by the determination means 13. Specifically, the control operation means 9 at the time of the earthquake respectively determines whether there is a user in the car 1, whether the safety device is not operating, or whether a predetermined time has passed since the emergency stop. When all the conditions are met, the operation control means 14 starts the automatic traveling of the car 1 toward the nearest openable area at a speed slower than the normal speed during normal operation (S112 to S114). .

In S112, the determination means 13 determines the presence or absence of a user in the car 1 based on the detection result of the in-car user detection means 6. Moreover, the said door opening possible area means the area | region (section) in which the door opening operation | movement is possible among the raising / lowering strokes of the cage | basket | car 1. FIG. Specifically, the car 1 and the landing door (or the door of the emergency landing entrance) are opposed to the stop floor in the normal operation and the emergency landing entrance, and the door driving device (see FIG. It means the area that can be opened by (not shown).

After S114, when the car 1 arrives at the nearest door openable area, the operation control means 14 stops the car 1 and performs the door opening operation to cause the user to escape from the car 1. Moreover, the operation control means 14 performs door closing operation | movement after that, and makes an elevator stop operation (S115). The elevator that has been suspended in S115 is inspected by a specialist engineer, and after it is confirmed that there is no abnormality, it is manually returned to normal operation (S108).

The nearest floor in S107 may be the openable area.

Next, other operations after S114 in FIG. 2 will be described based on FIG. Note that S201 in FIG. 3 is the same operation as S114 in FIG.

When the high level of the S-wave detector 4 is activated, the user's car 1 stops in the express zone and starts running at a low speed (or low speed) toward the nearest door openable area under the specified conditions. When it is done (S201), the seismic control operation means 9 determines whether or not the car 1 has reached the door openable area by the determination means 11 (S202). Then, when the car 1 reaches the door openable area, the operation control means 14 notifies the user in the car 1 that the door can be opened. Specifically, the operation control means 14 performs the notification by turning on or blinking the door opening button 1b of the car 1 or performing voice guidance from the announcement device 1c.

Then, when the stop of the car 1 is detected thereafter, the operation control means 14 automatically performs the door opening operation to cause the user to escape from the car 1 (S204, S205).

According to the first embodiment of the present invention, it is possible to prevent confinement in the express zone due to the occurrence of an earthquake as much as possible, and to safely let the elevator user escape from the car 1. In other words, even when the car 1 is traveling in the express zone, even if the maximum level earthquake is detected by the S wave detector 4, the car 1 should be run as far as possible to the nearest floor (closest openable area). And the confinement of users can be greatly reduced.

In addition, when the maximum level earthquake is detected by the S wave detector 4, there is a possibility that some sort of failure or the like has occurred in the elevator apparatus. For this reason, when the car 1 is urgently stopped in the express zone, the car 1 is resumed only when predetermined conditions such as the presence of a user in the car 1 and the safety device not operating are satisfied. You can do it. Further, by restarting the traveling of the car 1 at a speed slower than the normal speed, the degree of secondary damage due to the restarting of the traveling can be greatly reduced even if some sort of failure or the like occurs in the elevator apparatus. it can.

Furthermore, by notifying that the car 1 has arrived in the door opening possible area after the restart of the traveling, for example, even if the door opening operation is not performed for some reason in S205 of FIG. The user can be prompted to press the door open button 1b. If the car 1 stops at the emergency landing entrance / exit in the express zone, even if you look at the display inside the car 1 (indication of the current position) or look out from the car door window, May not recognize that it is an openable area. Therefore, when an emergency landing entrance is installed in the express zone, it is effective to provide the notification function.

The elevator apparatus according to the present invention can be applied to an elevator system in which an express zone is set in a part of the car's ascending / descending stroke, and further equipped with an earthquake-controlled operation function.
