Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an elevator control system in which each elevator control device of a plurality of elevators performs an earthquake control operation based on an earthquake detection signal from a seismometer.

[0002]

2. Description of the Related Art Generally, in an elevator control system including a plurality of elevators, an elevator control device is provided for each elevator. Then, an earthquake control operation is performed by each elevator control device.
For example, a plurality of types of seismometers are installed in an elevator machine room, and an earthquake detection signal from the seismometer is input to each elevator control device, and each elevator control device uses its own elevator based on the earthquake detection signal. Is to be operated by earthquake control.

[0003] As the seismometer, an extra low gal seismometer, a low gal seismometer, a high gal seismometer or the like is used, and these operate according to the detection level of the intensity of the earthquake. For example, if a set of extra-low gal and low gal seismometers are installed in the elevator machine room, depending on the strength of the earthquake,
First, the extra low gal seismometer operates, and then the low gal seismometer operates. The earthquake detection signals from these two types of seismometers are transmitted to each elevator control device using a signal line system. That is, the earthquake detection signal from the seismograph is output to the signal line of the signal line system, distributed on the way by the distributor, branched into a number of signal lines, and transmitted to each elevator control device.

[0004] When the elevator control device detects a seismic detection signal from the seismometer, the elevator control device performs a seismic control operation according to the detected earthquake level. For example, when detecting an earthquake detection signal from the extra-low Gul seismometer, the elevator control device performs an earthquake control operation in which the elevator is landed on the nearest floor and automatically returns after a predetermined time (for example, 60 seconds) elapses. When an earthquake detection signal from the low galle seismometer is detected, the elevator is landed on the nearest floor, and thereafter, the elevator is stopped until the low gal seismometer is reset. Thus, an appropriate earthquake control operation is performed according to the earthquake detection level.

[0005] When a high-galle seismometer is installed in addition to the extra-low gal and low-gal seismometers, when a low-gal or high-gal seismometer detects an earthquake detection signal, Then, it is determined whether or not the elevator is traveling in the express section. If the elevator is not traveling in the express section, the elevator is landed on the nearest floor, and then the elevator is stopped until the low-gul seismometer is reset.

On the other hand, when the elevator is traveling in an express section, it is determined whether or not the elevator is in a zone where landing can be performed within a predetermined time (for example, 10 seconds). Land on the nearest floor. And
After that, the operation stops until the low gal or high gal seismometer is reset. If landing is impossible, an emergency stop is performed. At that time, if the seismic detection signal of the high-galle seismometer is detected, the landing is performed manually, and if the high-galle seismic detection signal is not detected, the elevator and the counterweight separate automatically after one minute. I drive at a low speed to the nearest floor and land.

[0007]

However, when a high-galle seismometer is installed in addition to the extra-low gal seismometer and the low-gal seismometer, the seismic detection signal from the high-gal seismometer is also changed. This would have to be input to the elevator control. In other words, the seismic detection signals from the three types of seismometers must be transmitted using each signal line, distributed along the way, and transmitted to each elevator control device using a number of signal lines. .

[0008] As described above, when a high-galle seismometer is installed in addition to the extra-low gal and low-gal seismometers, many signal lines must be installed in the signal line system. The number of wirings in the line system was increased and complicated.

Therefore, there is a conventional serial transmission line system in which an earthquake detection signal from a seismometer is serially transmitted to each elevator control device using a serial transmission line. However, a transmission abnormality occurs in the serial transmission line system. When this occurs, there is a possibility that the earthquake control operation cannot be performed in each elevator control device.

As described above, when the signal line system is replaced with the serial transmission line system, although the wiring of the signal line system is reduced, when an abnormal transmission occurs in the serial transmission line system, the earthquake detection signal is transmitted to each elevator. Since the control device cannot detect it, reliability cannot be ensured.

[0011] Therefore, in order to perform the earthquake control operation ensuring the reliability, even if a serial transmission line system is used, the special low-gal seismometer, the low-gal seismometer, and the high-gal seismometer are controlled individually. The signal line system connecting the device is used at the same time. That is, since a signal line system is provided in addition to the serial transmission line system, a signal line system is required in addition to the serial transmission line system, and the large number of wirings and the complexity of the circuit have not been solved.

[0012] An object of the present invention is to increase the number of wirings between a plurality of types of seismometers and each elevator control device,
An elevator control system capable of appropriately performing an earthquake control operation is provided.

Embodiments of the present invention will be described below. FIG. 1 is a configuration diagram of an elevator control system according to a first embodiment of the present invention. In FIG. 1, an elevator control device 1 is provided for each of a plurality of elevators. In FIG. 1, three elevator control devices 1
Are provided. The seismometers are provided in common in the machine room of the elevator. In the first embodiment, a special low-galle seismometer 2 and a low-galle seismometer 3 are provided.

The seismic detection signal of the extra-low Gul seismometer 2 is converted into a serial transmission signal by a transmission signal converter 4 of a serial transmission line system and transmitted to a serial transmission line 5. On the other hand, the earthquake detection signal of the low-gul seismometer 3 is transmitted to the signal line 6 of the signal line system.

In each elevator control device 1, the transmission signal converter 7 converts the serial transmission signal from the serial transmission line 5 of the serial transmission line system into an earthquake detection signal again, and the transmission abnormality detecting means 8 and the earthquake control discriminating means. 9 is output.
The transmission abnormality detecting means 8 detects an abnormality of the serial transmission line system composed of the transmission signal converters 4 and 7 and the serial transmission line 5, and when an abnormality of the serial transmission line system is detected, the fact is notified. Is output to the seismic control determining means 9.

The earthquake control discriminating means 9 is provided for detecting an earthquake detection signal of the extra-low Gul seismometer 2 obtained through a serial transmission line system,
Low-gul seismometer 3 obtained via signal line 6 of signal line system
The type of the seismic control operation is determined based on the earthquake detection signal and the transmission abnormality signal from the transmission abnormality detecting means 8. The type of the seismic control operation determined by the seismic control determining means 9 is input to the seismic control operation control means 10, and the seismic control operation control means 10 performs the seismic control operation based on the type.

As described above, the earthquake detection signal from the extra-low galle seismometer 2 is transmitted to each elevator control device 1 through the serial transmission line system, and the earthquake detection signal from the low-gal seismometer 3 is transmitted through the signal line system. The elevator control devices 1 are transmitted to the respective elevator control devices 1, and each elevator control device 1 performs its own earthquake control operation based on the earthquake detection signal and the abnormal signal of the serial transmission line system.

FIG. 2 is a flowchart showing the operation of the elevator control device 1 according to the first embodiment of the present invention.

First, the earthquake control discriminating means 9 of the elevator control device 1 uses the serial transmission line 5 and the transmission signal converter 7 to input the earthquake detection signal of the extra-low gal seismometer 3 (hereinafter, extra-low gal signal). Is determined (S1).
01). When the extra-low gal signal is turned on, that is, when the extra-low gal seismometer 3 detects an earthquake detection signal, it is determined whether or not the transmission abnormality detection means 8 detects an abnormality in the serial transmission line system ( S102). When an abnormality has occurred in the serial transmission line system, since the reliability of the extra-low gull signal is low, an earthquake detection signal of the low gull seismometer 3 obtained via the signal line 6 (hereinafter referred to as a low gull signal) ) Is determined (S103).

In this determination, if the low gull signal is off, the seismic control determining means 9 determines that the type of the seismic control operation is extra low gull processing I, and if the low gull signal is on, The seismic control determining means 9 determines that the type of the seismic control operation is the low galling processing B.

That is, if the low gull signal is off in the judgment of step S103, the earthquake control discriminating means 9 estimates that an earthquake that does not reach at least the low gull level is detected, and issues a command for extra low gull processing I. It is sent to the earthquake control operation control means 10. The earthquake control operation control means 10 receives the command of the special low gull processing I and executes the earthquake control operation of the special low gull processing I.

First, operate the elevator to the nearest floor,
Landing on the nearest floor (S202). Then, the elevator is temporarily stopped and the service is temporarily stopped (S2).
03). In this case, since the serial transmission line system is in an abnormal state, the seismic detection signal of the extra-low gull seismometer 2 cannot be reliably detected. However, since the seismic detection signal of the low-gull seismometer 3 is off, an earthquake occurs. Even if it does, it can be estimated that it is at least an earthquake that does not reach the low galle level. Therefore, a predetermined time (for example, 180 seconds) longer than a predetermined time (for example, 60 seconds) in a normal case is counted (S204),
In the meantime, after temporarily suspending the operation service of the elevator, the extra-low galling signal of the transmission signal converter 7 is reset (S205) to prepare for the restart of the operation service of the elevator. Thereafter, the elevator operation service is restarted (S1
04), the seismic control operation processing of the extra low gal processing I is completed.

On the other hand, step S in the earthquake control determining means 9
When the low gull signal is ON in the low gull signal ON determination of 103, the seismic control determining means 9 performs the low gull processing B
Is issued to the earthquake control operation control means 10. The earthquake control operation control means 10 receives the command for the low gull processing B and executes the earthquake control operation of the low gull processing B. In this low galling processing B, the elevator is operated to the nearest floor, and is landed on the nearest floor (S207). After landing on the nearest floor, the service of the elevator operation is interrupted (S105). In this case, the operation service of the elevator is interrupted until the low-gul seismometer 3 is reset, and the earthquake control operation processing is completed.

Next, step S in the earthquake control discriminating means 9
In the transmission abnormality occurrence determination in 102, when the occurrence of the transmission abnormality is not detected, it is in a state where the extraordinary low Gull earthquake is continuously detected as usual. Therefore, a low gull signal ON determination is made as to whether or not the low gull seismometer 3 has detected the earthquake detection signal (S106).

In this determination, if the low gull signal is off, the seismic control determining means 9 determines that the type of the seismic control operation is the special low gull processing L. If the low gull signal is on, The seismic control determining means 9 determines that the type of the seismic control operation is the low galling processing B.

That is, when the low galle signal is off in the judgment of step S106, the seismic control judging means 9 judges that an extremely low gal level earthquake has been detected since the serial transmission line system is not abnormal. it can. Therefore, the earthquake control discriminating means 9 outputs a command for the extra-low gull processing L to the earthquake control operation control means 10. The earthquake control operation control means 10 receives the command of the special low gull processing L and executes the earthquake control operation of the special low gull processing L.

In the seismic operation control of the special low gar treatment L, the elevator is operated to the nearest floor and is landed on the nearest floor (S209). Then, the elevator is temporarily stopped and the service is temporarily stopped (S210). In this case, since the serial transmission line system is not in an abnormal state, the earthquake detection signal of the extra-low gul seismometer 2 is reliable, so it is determined that the extra-low gul signal is on. Therefore, a predetermined time (for example, 60 seconds) in a normal case is counted (S211), during which the operation service of the elevator is temporarily interrupted, and then the extra-low Gul seismometer 2 is reset through the serial transmission line 5 (S212). To prepare for the resumption of elevator service. Thereafter, the elevator operation service is resumed (S
104), the seismic control operation processing of the extra low gal processing L is completed.

On the other hand, step S in the earthquake control determining means 9
In the low gull signal ON determination of 106, if the low gull signal is ON, the seismic control determining means 9 determines that an earthquake of a low gull level or higher has been detected and issues a command for the low gull processing B to the seismic control. Output to operation control means 10. The earthquake control operation control means 10 receives the command for the low gull processing B and executes the earthquake control operation of the low gull processing B. In this low galling processing B, the elevator is operated to the nearest floor, and is landed on the nearest floor (S207). After landing on the nearest floor, the service of the elevator operation is interrupted (S105). In this case, the operation service of the elevator is interrupted until the low-gul seismometer 3 is reset, and the earthquake control operation processing is completed.

Step S in the earthquake control discriminating means 9
When the extra-low gull signal is turned off in the extra-low gull signal on judgment 101, the earthquake control discriminating means 9 judges whether or not the transmission abnormality detecting means 8 has detected an abnormality in the serial transmission line system ( S108). If an abnormality has occurred in the serial transmission line system, the presence or absence of an earthquake detection signal (low gull signal) of the low gull seismometer 3 obtained via the signal line 6 because the reliability of the extra-low gull signal is low. Is determined (S10
9).

If the low gull signal is ON in this determination, the seismic control determining means 9 determines that the type of the seismic control operation is low gull processing B. On the other hand, if the signal is low, the earthquake control discriminating means 9 determines that a mere transmission error has occurred and performs the transmission error processing (S110), and outputs a service continuation processing command to the earthquake control operation control means 10. Then, the earthquake control operation control means 10 receives the command and continues the elevator operation service, and the earthquake control operation processing is completed.

Step S in the earthquake control discriminating means 9
If no transmission error is detected in the transmission error occurrence determination of 108, the seismic control determining means 9 has a low reliability of the extra-low gull signal. It is determined whether there is a detection signal (low galling signal) (S111).

If the low gull signal is on in this determination, the seismic control determining means 9 determines that the type of the seismic control operation is low gull processing B. On the other hand, if the low signal is off, the earthquake control discriminating means 9 determines that no earthquake has been detected and performs an earthquake non-detection process (S112), and issues a service continuation processing command to the earthquake control operation control means 10. Upon receiving the command, the seismic control operation control means 10 continues the elevator operation service and the seismic control operation processing is completed.

As described above, according to the first embodiment, by replacing a part of the signal line system with the transmission line, the number of wirings can be reduced and the wiring circuit can be simplified, and the earthquake determination can be made. Reliability can be maintained at the conventional level.

That is, when the transmission abnormality detecting means 8 detects an abnormality in the serial transmission line system, the operation service of the elevator is continued or interrupted depending on the ON / OFF state of the earthquake detection signal of the low-gul seismometer 3 obtained from the signal line system. , The elevator can be safely operated even when an abnormality occurs in the serial transmission line system.

In the above description, the seismic detection signal of the low-galle seismometer 3 is transmitted through the signal line 6. However, the seismic detection signal of the low-galle seismometer 3 is transmitted through the signal line 6 and the transmission line 5. However, it may be transmitted. Further, the transmission signal converter 7 and the transmission abnormality detecting means 8 may be realized by software on one microcomputer, or the transmission signal converter 7, the transmission abnormality detecting means 8 and the earthquake control discriminating means 9 may be implemented by one microcomputer. The above may be realized by software. Further, the transmission signal converter 7, the transmission abnormality detection means 8, the earthquake control discrimination means 9, and the earthquake control operation control means 10 may be realized by software on one microcomputer.

Next, a second embodiment of the present invention will be described. FIG. 3 is a configuration diagram of an elevator control system according to a second embodiment of the present invention. This second embodiment is different from the first embodiment shown in FIG. 1 in that a high-gul seismometer 11 is additionally provided, and a high-gul seismometer is provided via a transmission signal converter 4 and a serial transmission line 5. 11 is transmitted to each elevator control device 1. Then, each elevator control device 1 performs the earthquake control operation in consideration of the earthquake detection signal of the high-gul seismometer 11. This is to enable the operation including the earthquake control operation in the express zone of the elevator.

In each elevator control device 1, the transmission signal converter 7 converts the serial transmission signal from the serial transmission line 5 of the serial transmission line system into an earthquake detection signal again, and the transmission abnormality detecting means 8 and the earthquake control discriminating means. 9 is output.
The transmission abnormality detecting means 8 detects an abnormality of the serial transmission line system composed of the transmission signal converters 4 and 7 and the serial transmission line 5, and when an abnormality of the serial transmission line system is detected, the fact is notified. Is output to the seismic control determining means 9.

The seismic control discriminating means 9 is provided for detecting the respective low-gul seismometer 2 and the high-gul seismometer 11 obtained through the serial transmission line system and for detecting the low-earth signal obtained through the signal line 6 of the signal line system. The type of the seismic control operation is determined based on the earthquake detection signal of the gull seismometer 3 and the transmission abnormality signal from the transmission abnormality detection means 8. The type of the seismic control operation determined by the seismic control determining means 9 is input to the seismic control operation control means 10, and the seismic control operation control means 10 performs the seismic control operation based on the type.

As described above, the earthquake detection signals from the extra-low gal seismometer 2 and the high gal seismometer 11 are transmitted to the respective elevator control devices 1 via the serial transmission line system. The signal is transmitted to each elevator control device 1 through a signal line system, and each elevator control device 1 operates its own elevator in a seismic control operation based on the earthquake detection signal and the abnormal signal of the serial transmission line system. ing.

FIG. 4 is a flowchart showing the operation of the seismic control determining means 9 of the elevator control device 1 according to the second embodiment of the present invention. Steps S307 and S313 are added to the operation flowchart of the earthquake control determining means 9 of the first embodiment shown in FIG.

In step S307, if the low gull signal is ON in the low gull signal ON determination in step S106, it is again determined whether or not the transmission abnormality detecting means 8 has detected an abnormality in the serial transmission line system. It is determined whether or not the earthquake detection signals of the extra-low and high-gul seismometers 2 and 11 obtained via the serial transmission line system are reliable. Then, when an abnormality is detected in the serial transmission line system, the earthquake control operation control means 10 executes the high control processing J of the earthquake control operation including the express zone as described later. On the other hand, if no abnormality is detected in the serial transmission line system, the seismic control operation control means 10 controls the seismic control operation including the express zone in the low control process K as described later.
Execute

Similarly, in the case of step S313, if the low gull signal is ON in the low gull signal ON determination in step S111, the transmission abnormality detecting means 8 again detects the abnormality of the serial transmission line system. Then, it is determined whether or not the earthquake detection signals of the extra-low Gul seismometer 2 and the high Gul seismometer 11 obtained via the serial transmission line system are reliable. Then, when an abnormality is detected in the serial transmission line system, the earthquake control operation control means 10 executes the high control processing J of the earthquake control operation including the express zone as described later. On the other hand, when no abnormality is detected in the serial transmission line system, the seismic control operation control means 10 executes a low-gull processing K of the seismic control operation including the express zone as described later.

Steps S103 and S103
When the low gull signal is ON in the low gull signal ON determination at 109, as described later, the earthquake control operation control means 10
In the above, when the high garment processing J of the earthquake control operation including the express zone is executed, and no abnormality is detected in the serial transmission line system, the earthquake control operation control means 10 as described later causes the special low garment shown in FIG. Execute processing I.

Step S109 and step S109
If the low gull signal is determined to be OFF in the low gull signal ON determination of 111, the seismic control operation control means 10 will be described later.
In, after the transmission abnormality or the earthquake non-detection processing, the continuation processing O of the elevator operation service is executed.

FIG. 5 is a flowchart showing the operation of the earthquake control operation control means 10 of the elevator control device 1 according to the second embodiment of the present invention. Extra low galling I, L
Is the extra-low gull processing I of the first embodiment shown in FIG.
Since it is the same as L, its description is omitted. Further, the continuation processing O is the same, so that the description is similarly omitted.

First, the high gull processing J of the earthquake control operation control means 10 is performed in step S103 of the earthquake control determination means 9;
This processing is executed when the low gull signal is ON in the low gull signal ON determination in S109 and when it is determined in the steps S307 and S313 that the transmission abnormality has occurred in the serial transmission line system.

First, it is determined whether or not the elevator is traveling in the express zone (S407). If the elevator is traveling in the express zone, the elevator is temporarily stopped (S408). Then, after the emergency stop, the vehicle is landed on the nearest floor at low speed by manual operation (S409).
On the other hand, when the elevator is not traveling in the express zone, the elevator is landed on the nearest floor as in the case of the low gull processing B shown in FIG. After landing on the nearest floor, the service is suspended until the seismometer is reset (S105), and the earthquake control operation processing is completed.

As described above, when the transmission abnormality detecting means 8 detects an abnormality in the serial transmission line system while the earthquake detection signal of the low-gul seismometer 3 obtained from the signal line system is on, (S
103, S307, S109, S313), assuming that the high-gul seismometer 11 has detected the earthquake detection signal, the earthquake control operation control means 10 performs the high-gul processing J.

Next, the low garbage processing K of the earthquake control operation control means 10 corresponds to step S307 in the earthquake control determination means 9,
This processing is executed when it is determined in S313 that the transmission error has not occurred in the serial transmission line system.

When there is no abnormality in the serial transmission line system,
Since the seismic detection signal of the high-gul seismometer 11 can be normally detected via the serial transmission line 5, if the seismic detection signal of the low-gul seismometer 3 is detected, the low-gul processing K is performed. . That is, in the second embodiment, the high-galle seismometer 11 is provided to perform the seismic control operation in the express zone of the elevator, so that the low-galle seismometer 11 in the first embodiment shown in FIG. In place of the process B, a low galling process K that includes the earthquake control operation in the express zone of the elevator is performed.

First, it is determined whether or not the elevator is traveling in the express zone (S412). If the elevator is traveling in the express zone, the elevator is temporarily stopped (S413). Then, it is determined whether or not there is an earthquake detection signal of the high-gul seismometer 11 detected via the serial transmission line 5 (S414). If the high-gul signal is on, the operation is manually performed at a low speed. Landing on the nearest floor (S415). If the high galle signal is off, the landing is automatically made at a low speed to the nearest floor (S416).
On the other hand, when the elevator is not traveling in the express zone, the elevator is landed on the nearest floor as in the case of the low gull processing B shown in FIG. After landing on the nearest floor, the service is suspended until the seismometer is reset (S105), and the earthquake control operation processing is completed.

As described above, when the transmission abnormality detecting means 8 does not detect an abnormality in the serial transmission line system when the earthquake detection signal of the low-gul seismometer 3 obtained from the signal line system is on, the earthquake control operation control is performed. Means 10 performs the low gull process K when the elevator is not traveling in the express zone.

As described above, according to the second embodiment, in addition to the effects of the first embodiment, when the low galvanic signal obtained from the signal line system is on, an abnormality occurs in the serial transmission line system. In the case where a low galle signal obtained from the signal line system is on in a state where an error has occurred in the serial transmission line system, the high galle seismometer 11 detects the earthquake detection signal. Therefore, the elevator can be operated safely even when an abnormality occurs in the serial transmission line system.

In the above description, the earthquake detection signal of the low-gul seismometer 3 is transmitted through the signal line 6. However, the earthquake detection signal of the low-gul seismometer 3 is transmitted through the signal line 6 and the transmission line 5 is transmitted. However, it may be transmitted. Further, the transmission signal converter 7 and the transmission abnormality detecting means 8 may be realized by software on one microcomputer, or the transmission signal converter 7, the transmission abnormality detecting means 8 and the earthquake control discriminating means 9 may be implemented by one microcomputer. The above may be realized by software. Further, the transmission signal converter 7, the transmission abnormality detection means 8, the earthquake control discrimination means 9, and the earthquake control operation control means 10 may be realized by software on one microcomputer.

As described above, according to the present invention, it is possible to perform reliable earthquake control while reducing the number of wires of the signal line transmission means.

That is, when an abnormality of the serial transmission line system is detected, the operation service of the elevator is continued, interrupted, and restarted depending on the on / off state of the seismic detection signal of the low-gul seismometer obtained from the signal line system. The elevator can be safely operated even when an abnormality occurs in the transmission line system.

Further, when a low galvanic signal obtained from the signal line system is turned on and an abnormality occurs in the serial transmission line system, or when an abnormality occurs in the serial transmission line system, the signal is obtained from the signal line system. When the low galle signal is on, the seismometer performs the seismic control operation on the assumption that the seismometer has detected the seismic detection signal. Elevator can be operated.
