Description

  The present invention relates to an elevator seismic control operation system, and more particularly to an elevator seismic control operation system that efficiently distributes early earthquake early warnings and performs seismic control operation of an elevator.

  Conventionally, as a device for determining the necessity of seismic control operation, in addition to a sensor for detecting the main shock (S wave) of an earthquake, a number of sensors for detecting an initial tremor (P wave) have been used. In recent years, the information on the sensors installed at observation points nationwide has been centrally managed, regardless of the P-wave detectors installed in the buildings, and the earthquake early warning that sends the scale and arrival time when an earthquake occurs The use is spreading.

  For example, in Patent Document 1, an earthquake information receiving terminal is provided for each elevator-installed building, an emergency earthquake notification signal transmitted via satellite communication is received by the receiving terminal, and data effective for the building is extracted. An elevator control device is disclosed in which an earthquake is detected earlier than a P-wave sensor installed in the station and the elevator is stopped at the nearest floor.

In Patent Document 2, an emergency earthquake warning is temporarily received by the central elevator monitoring center, where the distance between the epicenter and the elevator, the earthquake arrival time to the elevator, the earthquake scale, etc. are calculated, and seismic control operation is required. An elevator seismic control system that extracts a simple elevator and transmits a seismic control operation command via a network is disclosed.

  However, in the method of transmitting earthquake information to each building via the satellite communication, an expensive receiver is required for each building, so that the equipment cost proportional to the number of target buildings becomes enormous.

  In addition, the method of receiving the above earthquake early warning once at the elevator monitoring center, performing necessary calculations and distributing it to each elevator increases the load on the monitoring center that collectively manages the earthquake early warning when an earthquake occurs. It takes time for information to reach the elevator. In addition, when a failure occurs for some reason in the function of the monitoring center, the information does not reach all the information transmission destination elevators.

  The present invention has been made to solve the above-described problems of the prior art, and an object of the present invention is to provide an elevator seismic control operation system that can effectively use emergency earthquake warnings with less equipment and cost. .

  In order to achieve the above object, an elevator seismic control operation system according to a first aspect of the present invention receives an earthquake early warning sent from a source of an emergency earthquake early warning via a first network, and The first elevator control means for performing a seismic control operation, generating a predetermined command packet based on the emergency earthquake warning and distributing it to the second network, and receiving the distributed command packet, Second elevator control means for performing seismic control operation, wherein the first elevator control means is provided in at least one of a plurality of elevator installation buildings existing in each jurisdiction area obtained by dividing a specific area, and the remaining elevators The second elevator control means is provided in the installation building.

  According to the present invention, since there is no need to provide an expensive sanitary receiver for each elevator installation building, it is possible to efficiently use emergency earthquake warnings in more elevator installation buildings. In addition, since a system that centrally manages a large number of buildings is not used, command packet distribution processing can be distributed at low speed with high load.

  The elevator seismic control operation system according to the second aspect of the present invention monitors the operation state of the elevator apparatus in a plurality of elevator installation buildings via the second network, and any elevator installation building receives the earthquake early warning. Thus, a monitoring center that generates a predetermined command packet based on the earthquake early warning and distributes it to the second network, and an emergency earthquake bulletin sent from the source of the earthquake early warning via the first network First elevator control means for receiving and holding the monitoring information to that effect so that it can be monitored from the monitoring center, and receiving a command packet distributed from the monitoring center and performing seismic control operation of the own elevator device; A second control unit which receives a command packet distributed from the monitoring center and performs seismic control operation of the own elevator apparatus; The first elevator control means is provided in at least one of the plurality of elevator installation buildings existing in each jurisdiction area obtained by dividing the specific area, and the second elevator is installed in the remaining elevator installation buildings. Control means are provided.

  In the present invention, for example, by effectively utilizing an existing elevator monitoring system, it is not necessary to add extra equipment to the system, and emergency earthquake warnings can be efficiently used in many elevator installation buildings.

  In the third aspect of the present invention, the monitoring center preferentially monitors the first elevator control means. As a result, the monitoring center can promptly detect the reception of the earthquake early warning in a limited number of earthquake early warning receiving buildings.

  In the fourth aspect of the present invention, the second network is constructed on a local network. According to the present invention, since the local network is provided independently of the first network (global network), the command packet can be distributed at high speed.

  In the fifth aspect of the present invention, the first elevator control means generates different types of command packets according to the seismic intensity in the jurisdiction area and the seismic strength of the elevator installation building. If it carries out like this, various response | compatibility will be attained according to the seismic intensity in a jurisdiction area, and the seismic strength of the building where an elevator is installed.

  In the sixth aspect of the present invention, the monitoring center generates different types of command packets according to the seismic intensity in the jurisdiction area and the seismic strength of the elevator installation building.

  According to the present invention, a large number of elevator-installed buildings can use the earthquake early warning effectively and quickly with less equipment and cost.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an overall configuration diagram of an elevator seismic control operation system according to the first embodiment, and an earthquake information receiving building (first elevator control means) that has received an emergency earthquake warning reports a predetermined information based on the emergency earthquake warning. It shows a case where command information is generated and distributed to neighboring elevator installation buildings.

  In the figure, when an earthquake occurs at a certain point, the P wave from the epicenter is detected by the nearest seismometer, and the detection information is collected in the Japan Meteorological Agency 1. The Japan Meteorological Agency 1 analyzes the P wave to generate an earthquake early warning and sends it to a specific distribution server 2 via a dedicated line or the like. The distribution server 2 generates an earthquake early warning packet based on the received earthquake early warning, and transmits it to the elevator installation buildings A, B, etc. of distribution destinations with which the contract has been made in advance through the global networks GN1 to GN3. The elevator installation buildings A and B are also called earthquake bulletin reception buildings A and B in the sense of a building that directly receives the earthquake early warning packet from the distribution server 2.

  This emergency earthquake bulletin packet contains information such as the magnitude of the earthquake, the location of the epicenter (latitude, longitude, epicenter depth), the predicted seismic intensity at each point according to the distance from the epicenter, the arrival time of the seismic wave (S wave), etc. Is included. Here, the magnitude of the earthquake represents the magnitude (magnitude) of the energy generated by the earthquake, and the seismic intensity represents the degree of shaking of the earthquake at a certain point.

  The networks GN1 to GN3 are physically composed of telephone lines, optical lines, wireless lines, and the like, and constitute the Internet (global network) as a whole. On the Internet, a specific device can be selected by assigning a unique IP address to a device in the world. The first network in the present invention means a logical network connecting the distribution server 2 and the earthquake bulletin news receiving buildings A and B, and is physically constructed on a common global network. The second network means a logical network connecting the earthquake early warning receiving building A and the elevator installation buildings a1 and a2 and between the earthquake early warning reception building B and the elevator installation buildings b1 and b2. Also built on a common global network.

  In the earthquake bulletin receiving building A, the first elevator control means 3a (referred to as “first elevator control unit 3a” as appropriate in the drawing) is connected to the first and second networks to exchange communication packets. Received from the distribution server 2 and the distribution server 2, which stores predetermined information related to the distribution destination determination of the command packet generated at the time of receiving the earthquake early warning, and the distribution server 2. Based on the earthquake early warning, the delivery destination table storage unit 5 is referred to generate appropriate command packets according to the predicted seismic intensity in the jurisdiction area and the seismic strength of the elevator installation buildings a1 and a2 in the jurisdiction. A distribution control unit 6 that distributes to a2 and an elevator control unit 7 that performs various controls of the elevator apparatus 8 are provided. The same applies to Building B receiving earthquake bulletin.

  In the elevator installation building a1, the second elevator control means 9a (referred to as “second elevator control unit 9a” as appropriate in the drawing) receives control commands for receiving command packets sent via the second network. Unit (GNR) 10 and an elevator control unit 7 that performs various controls of the elevator apparatus 8. The same applies to the other elevator installation buildings a2, b1, b2. These first and second elevator control units 3a and 9a are realized by program execution of a CPU (not shown).

  With such a configuration, the first elevator control means 3a receives the earthquake early warning sent from the distribution server 2, performs the earthquake control operation of the own elevator device 8, and each predetermined earthquake based on the contents of the emergency earthquake early warning. A command packet is generated and distributed to the second network. On the other hand, the 2nd elevator control part 9a receives the command packet sent from the 1st elevator control means 3a, and performs the earthquake control operation of the own elevator apparatus 8. FIG.

  The schematic block diagram of the elevator apparatus 8 by embodiment is shown in FIG. A machine room is provided in the upper part of the elevator hoistway 13. In this machine room, an elevator control unit 7 that performs various controls such as a lifting speed and operation management of the car 14, and a car under the elevator control unit 7. A hoisting machine 15 that raises or lowers 14 is provided. A main rope 16 is wound around the hoisting machine 15, a car 14 is suspended at one end of the main rope 16, and a counterweight 18 is suspended at the other end via a deflecting wheel 17. . In addition, although the structure as shown in FIG. 2 was shown as a general structure of an elevator, for example, the present invention can be applied to an elevator that employs various structures such as a machine roomless elevator.

  The car 14 and the elevator control unit 7 are connected by a tail cord 19 suspended from the bottom of the car 14, and exchange necessary signals with the car 14. Although not shown, a display and a speaker are provided in the car 14 and the landings on each floor, and the user can take the following actions by guiding the earthquake information, the evacuation method from the elevator, and the evacuation route. Can be easily determined.

  A pit (bottom) of the elevator hoistway 13 is provided with a P-wave detector 20 a that senses the arrival of a P-wave, and the detected output is input to the elevator controller 7 via the hoistway cable 21. Further, the elevator machine room is provided with an S-wave detector 20b for detecting the arrival of an S-wave, and the detection output thereof is also input to the elevator controller 7. The elevator control unit 7 uses a known two-stage earthquake based on the detection signals of the P-wave detector 20a and the S-wave detector 20b (hereinafter these sensors are collectively referred to as “earthquake detector 20”). Control operation control.

  Next, an example of seismic control operation control will be outlined. When the P-wave detector 20a is activated due to the arrival of a P-wave, the earthquake display is lit in the car 14, and if possible, the information on the occurrence of the earthquake is notified by synthetic voice, and if the car 14 is running, the nearest Stop on the floor and open the door. If the door open button has not been pressed when a predetermined time (for example, about 1 minute) has elapsed, it is further determined whether or not the S-wave sensor 20b has been activated. Turns off the earthquake display in 14 and automatically returns to normal operation. When the S wave detector 20b is activated, the operation is suspended. In this case, the maintenance staff checks the elevator apparatus 8 and then returns to normal operation by resetting the seismic control operation state.

  In the present embodiment, it is possible to input an earthquake notification command and earthquake control operation commands L1 and L2 from the outside to such an elevator control unit 7, and this elevator control unit 7 receives an earthquake notification command. The fact that an earthquake has occurred is displayed, and if possible, earthquake information is notified by synthetic voice, and in this case, seismic control operation is not performed. On the other hand, when the seismic control operation command L1 is input, the same seismic control operation is performed as when the P-wave detector 20a is operated, and when the seismic control operation command L2 is input, the S-wave detector 20b is operated. The same seismic control operation as in the case of Therefore, in this embodiment, an advanced evacuation service can be provided by adding a simple configuration.

  In this embodiment, since the earthquake early warning is sent instantaneously based on the detection of the P wave near the epicenter, the earthquake control operation command is sufficiently earlier (for example, about ten or more seconds) than the S wave reaches this jurisdiction area. L1 or L2 is input. For this reason, each elevator installation building in the jurisdiction area enters the earthquake control operation sufficiently sooner than the seismic detector 20 operates. Moreover, since the seismic control operation control based on the seismic detector 20 is also performed in parallel, the elevator apparatus 8 is safely operated according to the actual seismic intensity.

  FIG. 3 is a diagram for explaining the stored contents of the delivery destination table storage unit 5 according to the first embodiment, in which the first elevator control means 3a is responsive to the seismic intensity in its own jurisdiction area and the seismic strength of the elevator installation building. A case is shown in which different types of command packets can be generated. In the figure, the identification ID of the elevator installation building is recorded in the column of “elevator installation building ID”, A is the earthquake breaking news receiving building, and a1 to a4 are the identification IDs of the delivery destination buildings of the command packet. Each column of predicted seismic intensity 1 to 7 in this jurisdiction area is provided in the “predicted seismic intensity” column, and each column of each seismic control operation control to be generated according to the seismic strength of each elevator installation building is provided in this column. Command levels 1 to 3 are recorded for each predicted seismic intensity.

  For example, when attention is paid to the earthquake early warning receiving building A, when the predicted seismic intensity = 1, the command level is 1, which means generation of an earthquake notification command. Further, when the predicted seismic intensity = 2, 3, the command level is 2, which means generation of the seismic control operation command L1. Further, when the predicted seismic intensity is 4 to 7, the command level is 3, which means generation of the seismic control operation command L2. In addition, the column where the command level is blank means that no command is generated. In the “IP address” column, the IP addresses of GNC4 and GNR10 are recorded, and these are used as the destination IP addresses of the command packet. The same applies to the other elevator installation buildings a1 to a4 in the jurisdiction area. However, in the earthquake bulletin receiving building A, a command is sent directly from the distribution control unit 6 to the elevator control unit 7.

  According to the present embodiment, it is possible to perform seismic control operation only for buildings that require seismic control operation according to the magnitude of the earthquake, and it is not necessary to stop the elevator service more than necessary. Further, according to the present embodiment, it is possible to control the elevator installation buildings in the jurisdiction area to be grouped in advance according to a predetermined condition, and to select a group that transmits a command packet according to the magnitude of the earthquake. It is. As the predetermined condition, in addition to the seismic strength of the building, a natural frequency that depends on the structure and height of the building, and the like can be given.

  FIG. 4 is a flowchart of the distribution control unit 6 according to the first embodiment, and this process is started when the GNC 4 receives the earthquake early warning. In step S1, information such as earthquake arrival time and predicted seismic intensity in this jurisdiction area is extracted from the received emergency earthquake bulletin. If this information is not included in the earthquake early warning, this jurisdiction area is known by a known method based on information on the magnitude of the earthquake (magnitude, etc.) and the location of the epicenter (latitude, longitude, epicenter depth). Calculate information such as earthquake arrival time and predicted seismic intensity.

  In step S2, the reference counter I in the distribution destination table storage unit 5 is initialized to “1”. In step S3, the delivery destination table storage unit 5 is referred to by the contents of the reference counter I, and a command level corresponding to the predicted seismic intensity for the target elevator installation building is extracted. In step S4, it is determined whether or not the command level ≧ 3. If YES, the earthquake control operation command L2 is set in step S5. If NO, the process of step S5 is skipped. In step S6, it is determined whether or not the command level ≧ 2. If YES, the earthquake control operation command L1 is set in step S7. If NO, the process of step S7 is skipped. In step S8, it is determined whether or not the command level ≧ 1, and in the case of YES, an earthquake notification command is set in step S9. If NO, the process of step S9 is skipped. In step S10, the reference counter I is incremented by one. In step S11, it is determined whether or not the table is finished. If NO, the process returns to step S3.

  In the case of YES, a command packet corresponding to the elevator installation building where the command is set in step S12 is distributed. However, the earthquake bulletin receiving building A is directly input to the elevator controller 7. In this case, the priority order of each command is determined in the order of “earthquake control operation command 2”> “earthquake control operation command 1”> “earthquake notification command”, and priority is given when a command with high priority is set. Commands with lower priority are not sent. However, when the seismic control operation command 1 or 2 is input, the elevator control unit 7 performs the earthquake display and voice notification originally provided corresponding to these earthquake levels.

  Within the jurisdiction, different types of command packets are generated depending on the predicted seismic intensity and the seismic strength of the building. By grouping these packets into the same types of commands, each of the elevator installation buildings corresponding to each group Can be broadcast.

  FIG. 5 is an image diagram of elevator seismic control operation processing according to the first embodiment, and specifically shows the state of command packet distribution in a specific area. For example, when the specific area is divided into jurisdiction areas Z1 to Z3 as shown in the figure, the specific area can be divided into three without excess or deficiency. In this jurisdiction area Z1, an earthquake bulletin receiving building A exists and is connected to neighboring elevator installation buildings a1 to a3 via a second network (global network). In addition, an earthquake bulletin receiving building B exists in the jurisdiction area Z2, and is connected to neighboring elevator installation buildings b1 and b2 by the second network. The same applies hereinafter. In this way, the minimum necessary (at least one for each jurisdiction area) earthquake bulletin news receiving buildings A to C are provided in the specific area, and an inexpensive and efficient system operation is possible.

  With such a configuration, the earthquake early warning sent from the distribution server 2 first reaches each earthquake early warning receiving building A to C (shown by the thick dotted line in the figure) of the distribution contract destination, and the earthquake that received this emergency earthquake early warning The bulletin receiving building A refers to its distribution destination table storage unit 5 and distributes a command packet corresponding to the seismic strength of each building to the elevator installation buildings a1 to a3 that need to be distributed (indicated by thin dotted lines in the figure). The earthquake bulletin receiving building B that has received the emergency earthquake bulletin refers to its distribution destination table storage unit 5 and distributes a command packet corresponding to the earthquake resistance strength of each building to the elevator installation buildings b1 and b2 that need to be distributed. The same applies hereinafter.

  In addition, you may increase the number of the earthquake early warning receiving buildings per jurisdiction area. By doing so, the path from the distribution server 2 to the earthquake breaking news receiving building can be duplicated, so that the reliability is high. On the other hand, command packets overlap in the jurisdiction area, but in each elevator installation building, the operation is started according to the first command packet, so that the command packet distribution can be substantially speeded up.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. Note that, in the second embodiment, the same components as those described in the first embodiment are denoted by the same reference numerals, and the description of the same components is omitted because it is duplicated.

  FIG. 6 is an overall configuration diagram of an elevator seismic control operation system according to the second embodiment. A monitoring center 23 is provided on the second network, and each of the elevator installation buildings A, a1, a2,. , B2,... Indicate a case where a monitoring packet and a command packet are exchanged with the monitoring center 23. This will be described in detail below.

  The monitoring center 23 includes a GNC 4, a distribution destination table storage unit 24, and a monitoring control unit 25. On the other hand, the first elevator control unit 3b includes a monitoring interface (IF) unit 26 that transmits and receives packets related to monitoring control to and from the monitoring center 23, and the second elevator control unit 9b also has a monitoring IF unit. 27. Further, the monitoring IF unit 26 holds the monitoring information indicating that the GNC 4 has received the earthquake early warning so that it can be monitored from the monitoring center 23, and also receives the command packet distributed from the monitoring center 23 to receive its own elevator. A command signal corresponding to the elevator control unit 7 of the device 8 is output. The monitoring IF unit 27 receives a command packet distributed from the monitoring center 23 and outputs a command signal corresponding to the elevator control unit 7 of the own elevator apparatus 8.

  In the monitoring center 23, the distribution destination table storage unit 24 stores information related to the distribution destination determination of various command packets generated when monitoring the reception of the earthquake early warning in the earthquake early warning receiving buildings A and B in a table. Yes. Although not shown, the delivery destination table storage unit 24 stores all the delivery destination table storage units 5 of FIG. 3 provided for each of the earthquake early warning receiving buildings A and B. By using such a delivery destination table storage unit 24, it is possible to efficiently perform command delivery control for all elevator installation buildings in a specific area.

  And this monitoring control part 25 usually monitors the operation state of each elevator apparatus 8 in all the elevator installation buildings A, a1, a2,..., B, b1, b2,. By detecting the reception of the earthquake early warning in B, the corresponding location of the delivery destination table storage unit 24 is referred to based on the contents, and various command packets corresponding to the predicted seismic intensity in the jurisdiction area and the seismic strength of the building are sent. Generate and distribute to each elevator installation building in the jurisdiction area. That is, when only the earthquake early warning reception building A receives the earthquake early warning, the command packet is distributed to the jurisdiction area, and when only the earthquake early warning reception building B receives the earthquake early warning, the instruction packet is distributed to the jurisdiction area. Thus, monitoring control for each jurisdiction area can be performed efficiently. Other configurations may be the same as those described with reference to FIG.

  Next, the operation of the monitoring control unit 25 will be described. FIG. 7 is a flowchart of the monitoring control unit 25 according to the second embodiment. In step S21, the first elevator control units 3b of the earthquake bulletin news receiving buildings A and B are preferentially monitored (scanned). This monitoring is performed, for example, by polling (scanning) monitoring packets to the monitoring center 23 or each elevator installation building and returning a response packet from each elevator installation building. In addition, the preferential monitoring of the earthquake early warning receiving buildings A and B is, for example, polling in the order of buildings “A, a1, B, a2, A, b1, B, b2,. That is, by closely monitoring the buildings A and B receiving the earthquake early warning, it is possible to quickly detect the reception status of the emergency earthquake early warning.

  In step S22, it is determined whether or not the earthquake early warning reception flag of the monitoring IF unit 26 is ON. If NO, the process returns to step S21. In the case of YES, in step S23, a part of the delivery destination table storage unit 24 that accompanies the receiving building is referred to, and a required command level is set for each elevator installation building in the jurisdiction area. In step S24, a command packet is distributed to the elevator installation building where the command level is set.

  FIG. 8 is an image diagram of the elevator seismic control operation processing according to the second embodiment, and specifically shows the state of monitoring or response packet exchange and command packet delivery in a specific area. The monitoring center 23 preferentially monitors (polls) the monitoring IF units 26 of the earthquake early warning receiving buildings A to C, and a response packet is returned from each earthquake early warning receiving building A to C (in the thin line in the figure). Show).

  In this state, for example, when the earthquake early warning is delivered to the earthquake early warning receiving building A, the monitoring IF unit 26 returns a response packet indicating that the own building A has received the early earthquake early warning to the monitoring center 23. Upon receiving this response packet, the monitoring control unit 25 refers to its own delivery destination table storage unit 24 and generates a command packet corresponding to the seismic strength of each building in the target elevator installation buildings A and a1 to a3. Deliver (indicated by a thin dotted line in the figure). The same applies to Building B receiving earthquake bulletin. When only the building A receives the earthquake early warning, the command packet is delivered only to the buildings A, a1, a2,..., But when both the buildings A and B receive the earthquake early warning, the building A , A1, a2,... And building B, b1, b2,.

  According to the second embodiment, by newly providing a monitoring system or using an existing monitoring system, in addition to normal system monitoring, monitoring of earthquake early warning reception and distribution of command packets associated therewith Can be performed efficiently.

Is provided.

  For this local network, a dedicated line using a telephone line, an optical line, a wireless line, etc., an Internet line, etc. can be used. When using the Internet line, there is a restriction on the use of IP addresses. In other words, in the Internet (global network), a specific device can be selected by assigning a unique IP address to devices all over the world. However, since the local network is originally a network established independently of the global network, In principle, any IP address can be assigned to the connected device. However, in order to avoid confusion when connecting to the Internet by mistake, P addresses that can be used on the local network are defined on the Internet, and if these IP addresses are found on the global network, they are neglected. ing. Other configurations may be the same as those described in FIG.

An earthquake bulletin receiving building A exists in the jurisdiction area Z1 and is connected to neighboring elevator installation buildings a1 to a3 by a local network LN1. The jurisdiction area Z2 includes an earthquake bulletin reception building B, which is connected to the nearby elevator installation buildings b1 and b2 through the local network LN2. The same applies hereinafter. In the third embodiment, the command packets can be distributed to more elevator buildings at a high speed by connecting each earthquake bulletin reception building and the neighboring elevator installation buildings via a local network.

  In each of the above embodiments, the specific area is divided by a plurality of jurisdiction areas composed of regular hexagons, but the present invention is not limited to this. Each jurisdiction region may have an arbitrary shape including circles and ellipses of various sizes, and there may be an overlapping portion between them. Since the command packet path is duplicated in the overlapping portion, the reliability of the command packet delivery is high. In each of the above embodiments, the earthquake bulletin news receiving buildings A and B or the monitoring center 23 generate and distribute various command packets. However, the earthquake early warning information may be delivered as it is.
