Description

  The present invention relates to an elevator control apparatus and its control method that uses emergency earthquake notification information, senses earthquake information earlier than an earthquake detector of a conventional P-wave sensor, and stops the elevator earlier to the nearest floor, and The present invention relates to a method for repairing an elevator control device.

Control operations during elevator earthquakes are controlled by seismometer signals installed in each building. However, there are cases where it is not possible to stop safely at the nearest floor even if the control operation is performed after an earthquake is detected during traveling. If there is not enough time since the earthquake was detected, the governor rope for the governor used to detect the speed of the elevator could be caught on the hoistway equipment by shaking the entire building while the elevator was running. Accidents such as damage to equipment for stopping installed in hoistways have occurred.
It is important to stop an elevator that is running on the nearest floor by detecting an occupying earthquake, or not to stop an elevator that is stopped, and to detect an earthquake at an early stage. It is well known that the initial tremor of the earthquake (P wave) is detected and controlled during an earthquake, but the further occurrence of the earthquake is captured as effective information for the building, and the elevator is controlled during an earthquake at an earlier time. Need to start.
FIG. 8 is a connection circuit diagram of a normal elevator seismic control operation device, where 10 is an elevator control panel, 40 is a P-wave sensor, 41 is a low-sensing seismometer, 42 is a high-sensing seismometer, 51 is a P-wave signal, 52 is a low-sensitive seismometer signal, and 53 is a high-sensitive seismometer signal. As a result, the initial vibration (P wave) of the earthquake is detected and the earthquake operation is performed.

Further, as a conventional technique, a method of transmitting an earthquake signal from a wide area earthquake detection system center to a plurality of buildings by wireless communication has been proposed (for example, see Patent Document 1).
In addition, as another conventional technology, by transmitting the earthquake monitoring information of the elevator monitoring center to each building by satellite communication, an earthquake signal is transmitted to each building at an early stage, eliminating the need for a seismometer installed in each building. There are some (see, for example, Patent Document 2).
Furthermore, as another prior art, there has been proposed an elevator seismic control operation system that can detect an earthquake sufficiently early, and can reliably detect an earthquake, and thus can perform safe and reliable control of the elevator. (For example, refer to Patent Document 3).

Japanese Patent Laid-Open No. 1-127583 JP-A-8-301544 JP 2004-284758 A

According to the conventional method described in Patent Document 1, since it is a method of transmitting to a plurality of buildings by wireless communication, communication to a plurality of buildings can be performed in a short time. There is a problem in that the communication processing time for a large number of buildings increases.
In addition, the method described in Patent Document 2 is a method in which communication is prioritized from buildings that are vulnerable to earthquakes, taking into account the past earthquake damage status for each building. If a remote seismic control signal is transmitted in consideration of the above, there is a problem of outputting a malfunction signal to an unnecessary area.
Furthermore, in the thing of patent document 3, it connects to the real-time earthquake information transmitter via a network, and the real-time earthquake information receiver which receives the information regarding the real-time earthquake information transmitted from this real-time earthquake information transmitter, ie, P wave, And the output of the seismic detector installed in each elevator, it is a method of controlling operation at the time of elevator earthquake, but since the real-time earthquake information transmission device is via a network, especially in the event of an earthquake, etc. There is a possibility that some kind of communication failure may occur on the way, and the received information is also related to normal P waves, so there is a limit even if it can detect earthquakes at an early stage, and there is a problem that it is still insufficient. It was.

Control operation during an earthquake that quickly detects an earthquake and stops the elevator at the nearest floor.

  In addition, the earthquake information receiving terminal detects an earthquake earlier than the P-wave sensor of the initial fine movement by the seismometer installed in the building, and performs an earthquake control operation to stop the elevator at the nearest floor.

  In the elevator control method according to the present invention, the emergency earthquake notification signal issued from the emergency earthquake notification network is received by the receiving antenna provided in the elevator installation building via the satellite communication station, the satellite ground antenna, the satellite, and the like. Installing the earthquake information received by the receiving antenna with the earthquake information receiving terminal, using the earthquake information receiving terminal to extract effective data for the building and using it without malfunction. And a step of detecting an earthquake earlier than the seismometer and stopping the elevator at the nearest floor by the control operation during the earthquake.

  Further, in the method for repairing an elevator control device according to the present invention, an elevator control device that is performing an earthquake control operation by a seismometer signal installed for each building is repaired, An emergency earthquake report signal issued from the emergency earthquake report network to the installed building is received from the satellite communication station, the ground antenna for satellites, the satellite, etc., and the emergency earthquake report information received by the receive antenna. An earthquake information receiving terminal that extracts valid data and uses it without malfunction is provided, and the earthquake information receiving terminal detects an earthquake earlier than the seismometer installed in the building and stops the elevator on the nearest floor The function to control the operation during earthquakes is added.

An earthquake information receiving terminal that extracts data effective for the building from earthquake report information and uses it without malfunctioning. The earthquake information receiving terminal detects an earthquake earlier than the seismometer installed in the building, and Because the operation control at the time of earthquake that stops the nearest floor is performed, the cost of satellite communication broadcasting is low, the commercially available BS antenna for broadcasting can be applied as the receiving antenna, and the earthquake information receiving terminal and control terminal are also inexpensive. There is no need to change the circuit on the elevator side, so this function can be easily spread and deployed.

Embodiment 1 FIG.
1 is a system configuration diagram showing the overall configuration of an elevator control apparatus according to Embodiment 1 of the present invention, FIG. 2 is an explanatory diagram showing the time effect of emergency earthquake notification, and FIG. 3 is in Embodiment 1 of the present invention. 4 is a connection circuit diagram showing a schematic configuration of the elevator control device, FIG. 4 is an explanatory diagram showing an example of the data area division of the Japan Meteorological Agency observation station, and FIG. 5 is a diagram for explaining data extraction for the building of the emergency earthquake notification data in the earthquake information terminal. It is a flowchart.

In FIG. 1, for example, a satellite communication station 3 such as a satellite communication company receives an emergency earthquake notification signal 2 from an emergency earthquake notification network 1 such as the Japan Meteorological Agency and transmits it to a broadcasting communication satellite 5 from a ground antenna 4 for satellite. Do. Then, in the elevator installation site 11 composed of each building or the like, an emergency earthquake notification from the broadcasting communication satellite 5 is received by the earthquake information receiving terminal 7 through the receiving antenna 6, and the elevator provided with the seismometer 9 through the control terminal 8. Control operation at the time of earthquake by the control panel 10 is performed.
The reception of data from the emergency earthquake notification network 1 by satellite broadcasting is different depending on the distance from the epicenter than the detection of the seismometer 9 installed in the building, but for example, when it is 200 km away as shown in FIG. Can be detected about 15 seconds earlier than the P wave of the initial fine movement and about 30 seconds earlier than the S wave of the main vibration.

  As shown in FIG. 3, the emergency earthquake notification signal 2 by satellite broadcasting is converted from the receiving antenna 6 through the earthquake information receiving terminal 7 into a signal for an elevator by the control terminal 8, and an emergency earthquake notification control signal 44 is output. To do. The emergency earthquake notification control signal 44 is connected to the elevator P-wave sensor 40 via a signal line 55. 41 is a low-sensitive seismometer, 42 is a high-sensitive seismometer, 51 is a P-wave signal, 52 is a low-sensitive seismometer signal, and 53 is a high-sensitive seismometer signal.

  As a result, the emergency earthquake notification signal 2 can be used without changing the elevator operation control circuit at the time of the earthquake. For example, an existing elevator including a connection circuit for an elevator control device as shown in FIG. Even in the building where is installed, it is possible to use the emergency earthquake notification signal by satellite broadcasting with a simple renovation work by simply installing the receiving antenna 6 and the earthquake information receiving terminal 7. Even if the emergency earthquake notification signal 2 cannot be used due to a malfunction, the seismometer control operation by the seismometer 9 installed in the building can operate.

Here, emergency earthquake notification will be described first. For example, an emergency earthquake notification from the Japan Meteorological Agency or the like is a mechanism that aggregates signals from the Meteorological Agency's emergency earthquake notification network 1 to the Japan Meteorological Agency and reports the seismic intensity and predicted seismic intensity at each location in real time.
The satellite communication station 3 such as a satellite communication company connected by a dedicated high-speed line transmits the emergency earthquake notification signal 2 of the Japan Meteorological Agency from the ground antenna 4 to the broadcasting communication satellite 5 and broadcasts the signal to the ground. ing.
The broadcasted emergency earthquake notification signal is received by a receiving antenna 6 (for example, a digital BS antenna) installed in each building, and is received by an earthquake information receiving terminal 7.
FIG. 2 shows an outline of communication time for emergency earthquake notification. At a location 200 km away from Tokyo, if the time taken to transmit data from seismometers installed on the Japan Meteorological Agency's emergency earthquake notification network to the Japan Meteorological Agency is 2 seconds, the time for satellite communication processing is 4 seconds. Then, it becomes possible to receive at the building after 6 seconds.
Considering the case of a normal seismometer installation, considering that the P wave of the initial tremor of the earthquake arrives 21 seconds later and the S wave of this vibration arrives 36 seconds later, The earthquake report can detect earthquake information 15 seconds earlier than the initial tremor P wave and 30 seconds earlier than the S wave of this vibration. This ensures that the car can be stopped before the express zone.

Next, extraction of emergency earthquake report data will be described. In emergency earthquake notification, earthquake information sensed by the Japan Meteorological Agency is broadcast via satellite, so selecting and using information that is valid for the building is indispensable to prevent malfunction.
FIG. 4 is an explanatory diagram showing an example of the data area division of the Japan Meteorological Agency observation station. It is necessary to set in advance a database for data extraction for the building that contains a database for extracting effective data for emergency earthquake notifications.
A database set in advance will be described with reference to FIG. Stations A, B, C, etc., where seismometers for Meteorological Agency emergency earthquake notifications with a distance of 100 km or less from the building are installed, are registered, and seismometers for Meteorological Agency emergency earthquake notifications of 200 km or less are installed. Register the existing stations J, K, L ...
As a condition for using emergency earthquake report data, seismic intensity of 4 or more is used as control data for seismic control operation of the building for station data of 100 km or less, and seismic intensity of 5 or more for station data of 200 km or less. Utilize the data.
As a result, an earthquake with a seismic intensity of 4 or higher can be detected in advance without causing the elevator of the building to stop at a seismic intensity of 2, in the same way that a conventional P-wave sensor previously stopped the elevator at the nearest floor. Extracting from satellite communication data, it is possible to control the elevator of the building at the time of earthquake control at an early stage.

Next, a data extraction flow for the building of emergency earthquake report data in the earthquake information terminal will be described with reference to FIG.
The emergency earthquake report data broadcast by satellite broadcasting is received by the receiving antenna 6 of the building (step S1). The earthquake reception data is transmitted to the earthquake information receiving terminal 7, and a data comparison process is performed with reference to the database registered in advance (step S2). Next, in step S3, confirmation is performed in order not to prevent the same elevator control operation during the earthquake (closest floor stop) processing.
When the control operation process at the time of earthquake is performed for the first time, it is the process of step S4, and it is confirmed whether or not there is data of seismic intensity 4 or more in the 100km group meteorological agency observation data in the database shown in FIG. If there is data of seismic intensity 4 or more in step S4, the elevator is stopped nearest to the floor (step S5). This can be realized by making the terminal of the conventional P-wave sensor 40 significant and performing the same processing at an early stage.
If it is not yet shaken at the station 100 km away in step S4, it is checked in step S6 whether there is data of seismic intensity 5 or higher in the JMA station data 200 km or less from the site. If there is data of seismic intensity 5 or more in step S6, the elevator is stopped nearest to the floor (step S5). Similarly to the above, this can be realized by making the terminal of the conventional P-wave sensor 40 significant and performing the same processing at an early stage.
If the observation station 200 km away is not yet shaken at step S6, the earthquake control operation using the emergency earthquake report data will be terminated and the conventional seismometer 9 installed in the building will shift to the earthquake control operation. To do.
Once it is determined in step S3 that there is a nearest floor stop command for the elevator, time counting is started in step S7, the duration of the nearest floor stop command is monitored in step S8, and a predetermined time, for example, about 40 seconds. Outputs an elevator nearest floor stop signal for a long time so that the elevator can surely stop at the nearest floor (step S9). When a predetermined time, for example, 40 seconds elapses in step S8, the nearest floor stop signal is stopped and released (step S10).
The satellite communication broadcasting cost according to the first embodiment is low, the receiving antenna can be a commercially available BS antenna, etc., the earthquake information receiving terminal and the control terminal are also inexpensive, and the circuit change on the elevator side is also possible. Since it is not necessary, the spread and development of this function can be expected easily.

FIG. 6 is a system configuration diagram configured to be able to grasp the effect of the emergency earthquake notification of the elevator control apparatus according to Embodiment 2 of the present invention, and FIG. 7 is an explanatory diagram illustrating an example of management data stored in the control terminal. It is.
In FIG. 6, 6 is a receiving antenna, 7 is an earthquake information receiving terminal, 8 is a control terminal, 9 is a seismometer, 10 is an elevator control panel, 40 is a P-wave sensor, 41 is a low-sensing seismometer, and 42 is a high-sensing earthquake. 44 is an emergency earthquake notification control signal, 51 is a P-wave signal, 52 is a low-sensing seismometer signal, and 53 is a high-sensing seismometer signal.
The P-wave sensor 40 is taken into the control terminal 8 and the relay Q47 for data management 2 is driven. A parallel signal of the contact signal 45 of the relay Q47 and the emergency earthquake notification control signal 44 is input to the elevator control panel 10 as a P-wave signal 51 for earthquake control operation on the elevator side. As a result, like the P wave signal of the building, the elevator stops at the nearest floor at the perceived timing.
The timing of emergency earthquake notification is also managed as the signal 43 of the data management 1.
Similarly, the signal of the low-sensing seismometer 41 is also connected to the elevator control panel 10 via the control terminal 8 and managed as a signal of the data management 3.
The signal of the high-sensing seismometer 42 is the same, and is managed as the signal 49 of the data management 4.
In order to confirm the effect, in order to confirm how much the emergency earthquake report signal 44 is received at a timing earlier than the elevator stop, the elevator running signal 54 is taken into the control terminal and data management is performed. 5 as a signal 50.

これらのデータにより、緊急地震通報のデータが、従来のビル設置のＰ波センサーより、どの程度早く受信できたのか、(データ管理２)−（データ管理１）を示すことが可能である。また、エレベータ停止時刻よりどれくらい早く、エレベータを最寄階停止にできたのかを、(データ管理５)−（データ管理１）により確認することが出来る（１９秒前となる）。
通常の地震時管制運転では、Ｐ波等の初期微動を感知すると、エレベータを最寄階に停止させたり、停止中のエレベータは一定時間走行させない。
また、低感知地震計４１が動作すると、最寄階に停止し戸開した後は走行停止とする。Ｐ波の初期微動を感知してから最寄階に停止するまで時間が掛かるのは、高層ビルのエレベータであり、急行ゾーンなどで中間階に停止できないエレベータである。このようなエレベータの場合は、低感知地震計４１が動作した場合に１０秒程度で停止できるか否かを判断して、停止できない場合は急ストップさせる処置を取る。
高層エレベータの場合には、エレベータのスピードも高速であり、数秒でも早く地震を感知して、最寄階に停止することで、乗客を最も安全に避難させることができる。
地震感知の時刻が遅くなった場合には、走行中に本震が起こり、釣り合い重りのレール外れ、ロープ外れ、制御ケーブルの引っ掛かり、断線等の重大な故障が発生する恐れがある。
誤動作を起こして、むやみにエレベータを最寄階停止させないためには、地震情報受信端末の受信データの有効データの抽出も重要である。
緊急地震通報データの効果の把握を実際のデータを解析して、その効果を当該ビルの管理者に説明することは、他ビルヘの適用、拡大をすることにより、高層エレベータの地震時の安全性の向上を促進できることになる。
この実施の形態２による衛星通信放送費用も安価であり、受信アンテナも市販の放送用のＢＳアンテナ等が適用可能であり、地震情報受信端末、制御端末も安価であり、エレベータ側の回路変更も必要ないことから容易に本機能の普及・展開が期待できる。 Next, an example of management data stored in the control terminal will be described with reference to FIG.
Data management 1 is emergency earthquake notification time, data management 2 is P wave sensor detection time of the building, data management 3 is low detection seismometer detection time, data management 4 is high detection seismometer detection time, data management 5 is elevator stop It's time.
As data management 6, the estimated distance from the center to the epicenter is calculated and displayed.
Estimated distance to the epicenter with P wave velocity of 9.5km / sec and S wave velocity of 5.5km / sec is

With these data, it is possible to indicate (data management 2)-(data management 1) how early the emergency earthquake report data was received from the conventional P wave sensor installed in the building. In addition, it is possible to confirm (data management 5)-(data management 1) (19 seconds before) how early the elevator was able to stop at the nearest floor.
In normal seismic control operation, when an initial tremor such as a P wave is detected, the elevator is stopped at the nearest floor or the stopped elevator is not allowed to run for a certain period of time.
In addition, when the low-sensing seismometer 41 is operated, it stops at the nearest floor and is stopped after the door is opened. It is an elevator of a high-rise building that takes time until it stops at the nearest floor after sensing the initial tremor of the P wave, and it is an elevator that cannot stop at the intermediate floor in an express zone or the like. In the case of such an elevator, when the low-sensing seismometer 41 is operated, it is determined whether or not it can be stopped in about 10 seconds.
In the case of a high-rise elevator, the speed of the elevator is also high, and passengers can be evacuated most safely by detecting an earthquake as early as several seconds and stopping at the nearest floor.
If the time of earthquake detection is delayed, a mainshock will occur during travel, and serious troubles such as disengagement of the counterweight rail, disconnection of the rope, catching of the control cable, and disconnection may occur.
Extracting valid data from the received data of the earthquake information receiving terminal is also important in order to prevent malfunction and cause the elevator to stop at the nearest floor.
Understanding the effects of emergency earthquake report data by analyzing actual data and explaining the effects to the manager of the building can be applied to other buildings and expanded, and the safety of high-rise elevators during earthquakes It is possible to promote improvement.
The satellite communication broadcasting cost according to the second embodiment is low, the receiving antenna can be a commercially available BS antenna for broadcasting, the earthquake information receiving terminal and the control terminal are inexpensive, and the circuit change on the elevator side is also possible. Since it is not necessary, the spread and development of this function can be expected easily.
