Description

  The present invention relates to an earthquake control system for an elevator that promptly implements earthquake countermeasures for each elevator apparatus when an earthquake occurs.

  An elevator car installed in a large-scale building newly constructed in recent years, or an elevator apparatus installed in a medium-sized building, which is used by an unspecified number of people, has an elevator car. An S-wave seismic detector for detecting the main oscillation (S-wave) of an earthquake is provided in the machine room provided above the hoistway that moves up and down. For example, when this S-wave seismic detector detects a vibration level of 200 Gal or higher, measures such as stopping the elevator have been taken.

  However, in an earthquake, the initial tremor (P wave) comes before the main oscillation (S wave), so P wave seismic detection that detects the initial tremor (P wave) in the pit of the elevator hoistway. When a P-wave seismic detector detects a vibration level higher than a predetermined level, such as 100 Gal, for example, measures have been taken to switch the elevator operation from normal operation to seismic control operation.

In this seismic control operation, when the elevator car is moving in the hoistway, the car is stopped on the nearest floor and the users in the car are evacuated to the elevator hall on the nearest floor (Patent Document 1). reference). Thus, by taking earthquake countermeasures at the detection timing of the initial tremor (P wave) of the earthquake, the safety of the elevator user can be further improved.
JP 2002-46953 A

  However, in the conventional technology as described above, the earthquake control operation for the elevator is performed only by the vibration level detected by the P-wave seismic detector installed in each elevator apparatus. What is important is to stop the elevator car to the nearest floor quickly and safely, and to safely take the elevator user down to the elevator hall.

  The propagation speed of seismic waves (several km / s) is much slower than the propagation speed of electrical signals, so when a large-scale earthquake occurs, it is installed in an elevator system installed in the area near the earthquake epicenter. If it is possible to transmit the information of the existing seismic detector to the elevator device installed far from the earthquake epicenter, the earthquake countermeasures should be able to be executed earlier than the detection time of the seismic detector incorporated in each elevator device. .

  In addition, the installation of seismic detectors is not obligated by the current Building Standards Act. Therefore, elevators without seismic detectors cannot operate in seismic control. There was a possibility of causing a user's confinement accident.

  The present invention has been made in view of such circumstances, and by connecting a large number of elevator devices distributed and arranged in a wide area via a network, a region of occurrence of shaking in the wide area of the earthquake that has occurred The earthquake scale can be predicted, and each elevator system can start seismic control operation at the time of the earthquake before the actual seismic wave arrives, and the users in the car can be quickly evacuated to the elevator hall on the nearest floor The objective is to provide an elevator seismic control system that can further improve the safety for users and significantly reduce damage to elevator equipment.

  The present invention relates to a seismic control system for an elevator, in which a plurality of elevator apparatuses in which seismic detectors for detecting an earthquake are incorporated and distributed over a wide area are connected to a network, and a monitoring center for monitoring the plurality of elevator apparatuses. Applies to the system.

And in order to eliminate the said subject, the vibration data transmission means which transmits the vibration data detected with the own earthquake detector to a monitoring center via a network with respect to each elevator apparatus, and the vibration level of the detected vibration data When the seismic control operation execution means for executing the seismic control operation for the self-elevator and the seismic control operation execution command from the monitoring center via the network are received , the seismic control operation It comprises a prior execution means for judging the operation status and starting the seismic control operation when the self has not yet started the seismic control operation.

When the monitoring center receives vibration data from at least three elevator devices, the prediction center predicts an occurrence area and an earthquake scale in a wide range of the earthquake based on the vibration data, and the earthquake prediction Determination means for determining each elevator apparatus that is predicted to generate a vibration of a predetermined level or more based on the result, and execution command transmission means for transmitting an execution command for seismic control operation to each determined elevator apparatus via the network; It has.

In the elevator seismic control system configured as described above, for example, seismic detectors for detecting P waves are installed in a plurality of elevator apparatuses distributed in a wide range of prefecture units. When an earthquake occurs, vibration data is output from the earthquake detector and transmitted to the monitoring center via the network. Further, immediately when the vibration data output from the earthquake detector is equal to or higher than a predetermined level, the elevator apparatus starts executing the earthquake control operation. In addition, the monitoring center makes an earthquake prediction based on vibration data from at least three elevator apparatuses, and transmits an execution command for the earthquake control operation to each elevator apparatus. The elevator apparatus that has received the execution instruction for the seismic control operation does not execute the execution instruction for the seismic control operation received from the monitoring center because the seismic control operation has already been executed if an earthquake occurs nearby.

  On the other hand, in the case of an earthquake that has occurred in the distance, an instruction to execute seismic control operation arrives from the monitoring center before the seismic wave reaches the elevator system. Seismic control operation can be started, and users in the car can be quickly evacuated to the elevator hall on the nearest floor.

  According to another invention, in the above-described elevator earthquake control system, when an elevator apparatus not provided with an earthquake detector is connected to the network, the elevator apparatus is connected from the monitoring center via the network. When an execution command for seismic control operation is received, a seismic control operation executing means is provided for starting execution of seismic control operation for the self-elevator. Thus, even if an elevator apparatus not provided with an earthquake detector is incorporated in this system, it is possible to sufficiently ensure the safety of the user when an earthquake occurs.

Another invention relates to an earthquake seismic control system for an elevator in which a plurality of elevator devices distributed in a wide area are connected to a network, in which an earthquake detector for detecting an earthquake is incorporated.
Each elevator device transmits vibration data detected by its own seismic detector to other elevator devices via the network, and when the detected vibration data has a vibration level equal to or higher than a predetermined level, A seismic control operation executing means for executing seismic control operation, and an earthquake prediction means for predicting an occurrence area and an earthquake scale in a wide area of the earthquake based on vibration data received from at least three other elevator devices, Based on this earthquake prediction result, if it is predicted that vibration of a certain level or higher will occur in its own elevator system, the operational status of the earthquake control operation at the present time point is judged, and when the self has not yet started the earthquake control operation, Pre-execution means for starting seismic control operation.

  In such an elevator seismic control system, each elevator device holds the vibration data detected by the earthquake detector through the network so that each elevator device uses the vibration data detected by the other elevator devices. Thus, it is possible to predict an earthquake that will affect the elevator system of the vehicle, so that the earthquake control operation at the time of the earthquake can be started before the actual seismic wave arrives.

  In another aspect of the present invention, in the above-described elevator seismic control system, when an elevator apparatus not provided with an earthquake detector is connected to the network, the elevator apparatus provided with the earthquake detector is A determination unit that determines an elevator device that is not provided with an earthquake sensor that is predicted to generate a vibration of a predetermined level or more based on an earthquake prediction result in the earthquake prediction unit, and an earthquake to each of the determined elevator devices via a network Execution command transmission means for transmitting a control operation execution command. Furthermore, the elevator apparatus not provided with the seismic detector is provided with a seismic control operation execution means for executing the seismic control operation for the self-elevator when receiving an execution command for the seismic control operation via the network.

  Therefore, even in this case, even if an elevator apparatus not provided with an earthquake detector is incorporated in this earthquake control system, it is possible to sufficiently ensure the safety of the user when an earthquake occurs.

  In the present invention, since the occurrence area and the magnitude of the earthquake within the wide range of the earthquake that occurred are predicted, each elevator apparatus starts the earthquake control operation at the time of the earthquake occurrence before the actual earthquake wave arrives It is possible to quickly evacuate the user in the car to the elevator hall on the nearest floor, further improve the safety for the user, and greatly suppress the damage to the elevator equipment.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a schematic diagram showing a schematic configuration of an elevator earthquake control system according to a first embodiment of the present invention.

  For example, for a network 1 such as the Internet, for example, a plurality of elevator apparatuses 2 distributed in a wide range of prefectures and a single monitoring center 3 for monitoring the plurality of elevator apparatuses 2 are provided. It is connected.

  In each elevator device 2 installed in a building such as a building, an elevator car 5 is connected to one end of the main rope 6 in a hoistway 4 that penetrates from the lowest floor to the top floor of the building. A counterweight 7 is connected to the other end. The car 5 can be moved to an arbitrary floor by hoisting the main rope 6 with the hoisting machine 8 installed in the machine room above the hoistway 4. The pit 9 of the hoistway 4 is provided with a P-wave earthquake detector 10 that detects a P-wave that is an initial tremor of an earthquake, and vibration data detected by the P-wave earthquake detector 10 is used for the entire operation of the elevator. Is input to the main control unit 11 that controls. Further, an S-wave earthquake detector 12 for detecting an S-wave indicating the main shake of the earthquake is installed in the machine room, and vibration data detected by the S-wave earthquake detector 12 is also input to the main controller 11. Is done.

  In a control panel formed by a computer (not shown) provided in the machine room, in addition to the main control unit 11, in normal operation, a hall call registration device provided in an elevator hall on each floor, or in the car 5 There is provided a normal operation unit 13 for moving the car 5 to the floor designated by the hall call and car call input from the car call registration device provided in the car. Further, an earthquake control operation unit 14 is provided. When an execution command is input from the main control unit 11, the seismic control operation unit 14 stops the car 5 at the nearest floor and moves the user in the car 5 to the nearest floor when the elevator car 5 is moving. Retreat to the elevator hall. Then, the door is closed and the maintenance staff waits for inspection.

  The main control unit 11 operates the normal operation unit 13 in a state where no abnormal state including an earthquake has occurred. When vibration data is input from the P-wave earthquake detector 10, the vibration data is sent to the vibration data transmitter 15. The vibration data transmitter 15 incorporates the input vibration data into the transmission frame with its own position and the detection time of vibration data added, and the data server 17 of the monitoring center 3 via the communication unit 16 and the network 1. Write to.

  The main control unit 11 transmits the vibration data to the monitoring center 3 and simultaneously checks the vibration level of the vibration data. And when a vibration level is more than the regulation value of 150 Gal, for example with respect to this P wave, the normal operation part 13 is stopped and the seismic control operation part 14 is started.

  Further, the main control unit 11 receives an instruction for seismic control operation from the seismic analysis device 19 composed of a PC (personal computer) in the monitoring center 3 via the network 1 and the communication unit 16. When received, it is checked whether or not the seismic control operation unit 14 is in operation at the present time. If not, the seismic control operation unit 14 is activated. When in operation, the P-wave seismic detector 10 of the own elevator device 2 has generated vibrations exceeding the specified value, and the seismic control operation unit 14 is already in operation or has ended and the elevator is stopped. Because there is, do nothing.

  When the S-wave earthquake detector 12 detects a vibration level of, for example, 200 Gal or more, the elevator car 5 is stopped on the spot and communicated with the monitoring center 3 through an interphone provided in the car 5.

  Next, the structure and operation of the monitoring center 3 will be described. In the monitoring center 3, as described above, the data server 17 and the earthquake analyzer 19 that are independently connected to the network 1 are incorporated. The data server 17 stores and holds the vibration data of the P wave received from each elevator apparatus 2 distributed in a wide range within itself, and immediately sends it to the earthquake prediction unit 20 in the earthquake analyzer 19. To do.

  The earthquake prediction unit 20 in the earthquake analysis device 19 calculates the epicenter of the corresponding earthquake and the magnitude of the earthquake from a plurality of input vibration data. Specifically, since vibration data is sequentially detected from the P-wave detector 10 of the elevator device 2 close to the epicenter, each detection time difference from the first point at the installation point of each of the second and subsequent elevator devices 2 is analyzed. And determine the epicenter of the earthquake and the magnitude of the earthquake. The calculation of the epicenter and magnitude of this earthquake is based on the first few vibration data because the seismic waves of this earthquake need to be part of the wide area within the propagation period. Next, the seismogenic area and the earthquake scale in a wide area are predicted from the calculated epicenter and magnitude.

  And the determination part 21 determines each elevator apparatus 2 of the position predicted that the vibration more than the regulation level of 150 Gal mentioned above will arise based on this earthquake prediction result. The control operation instruction unit 22 transmits an execution command for the seismic control operation to each determined elevator apparatus 2 via the communication unit 23 and the network 1.

  FIG. 2 is a flowchart showing the overall operation of the main control unit 11 of each elevator apparatus 2. When the P-wave earthquake detector 10 in its own elevator apparatus 2 detects the P-wave of the earthquake and P-wave vibration data is input to the main control unit 11 (step S1), the vibration data is transmitted via the network 1. To the monitoring center 3 (S2). And when the vibration level of the said vibration data is more than the regulation level mentioned above (S3), the normal operation part 13 is stopped and the seismic control operation part 14 is started (S4). When the car 5 stops at the nearest floor in the seismic control operation section 14 and the passenger in the car 5 retreats to the elevator hall on the corresponding floor, the door is closed, the elevator is stopped (S5), and inspection is performed by maintenance personnel. Transition to the wait state.

  Further, when an execution command for the seismic control operation is input from the monitoring center 3 in S6, it is checked whether or not the seismic control operation unit 14 is in operation at the present time, and if not in operation (S7). Then, the earthquake control operation unit 14 is activated (S8). When the seismic control operation ends, the door is closed, the elevator is stopped (S9), and the state shifts to a state of waiting for inspection by maintenance personnel.

  And when it is in operation (S7), the P-wave seismic detector 10 of its own elevator device 2 has generated a vibration that exceeds the specified value, and the seismic control operation unit 14 is already in operation or has ended. Since the elevator is stopped, do nothing.

  FIG. 3 is a flowchart showing the overall operation of the monitoring center 3. When vibration data is received by the data server 17 from the elevator apparatus 2 (step Q1), it is stored in a memory (Q2). For example, when there are three or more vibration data, the epicenter and magnitude of the earthquake are calculated. Predict the seismogenic area and magnitude in a wide area (Q4). Based on this earthquake prediction result, each elevator apparatus 2 at a position where it is predicted that a vibration of a specified level of 150 Gal or more will be generated is determined (Q5). Then, an execution command for the seismic control operation is transmitted to each determined elevator device 2 (Q6).

  In the elevator seismic control system of the first embodiment configured as described above, a P-wave earthquake sensor 10 is attached to each elevator apparatus 2 distributed in a wide area. When an earthquake occurs, vibration data is output from the P-wave earthquake detector 10, so that the elevator apparatus 2 starts executing the earthquake control operation immediately when the vibration data is equal to or higher than a predetermined level. At the same time, the detected vibration data is transmitted to the monitoring center 3 via the network 1. Then, an execution command for the seismic control operation is sent to each elevator apparatus 2 at a position where it is predicted that vibration above the specified level will occur.

  Therefore, in each elevator apparatus 2, when an earthquake occurs nearby, the seismic control operation is performed based on the vibration data output from its own P-wave earthquake sensor 10. On the other hand, for an earthquake that occurred in the distance, the seismic control operation is performed according to a command from the monitoring center 3 before the seismic wave of this earthquake arrives. It is important that the start time of this seismic control operation is as early as 1 second when an earthquake is actually expected. Therefore, users in the car 5 can be quickly evacuated to the elevator hall on the nearest floor. The safety for the user can be further improved, and damage to the elevator apparatus 2 can be greatly suppressed.

(Second Embodiment)
FIG. 4 is a schematic diagram showing a schematic configuration of an elevator earthquake control system according to the second embodiment of the present invention.

  Other configurations and operations of the elevator apparatus 2 and the monitoring center 3 are substantially the same as those of the elevator apparatus 2 and the monitoring center 3 of FIG. Note that the monitoring center 3 also sends an instruction to execute the seismic control operation to the elevator apparatus 2a not provided with the seismic detectors 10 and 12 if the vibration condition is satisfied, as with the other elevator apparatuses 2.

  Since no vibration data is input to the main control unit 11a of the elevator apparatus 2a in the second embodiment when an earthquake occurs, the elevator apparatus 2a does not transmit vibration data to the monitoring center 3. However, when the control operation instruction receiving unit 18 receives a seismic control operation execution command from the monitoring center 3, the main control unit 11a activates its own seismic control operation unit 14.

  As described above, in the earthquake control system of the second embodiment, even when the elevator apparatus 2a not provided with the earthquake detectors 10 and 12 is incorporated in the system, it is used when an earthquake occurs. The safety of the person can be secured sufficiently.

(Third embodiment)
FIG. 5 is a schematic diagram showing a schematic configuration of an elevator earthquake control system according to a third embodiment of the present invention. The same parts as those in the elevator earthquake control system according to the first embodiment of the present invention shown in FIG.

  In the elevator earthquake control system of the third embodiment, the monitoring center 3 is not connected to the network 1, and a plurality of elevator apparatuses 2b having an earthquake prediction function are connected.

In addition, a vibration data receiving unit 24, an earthquake prediction unit 25, and a determination unit 26 are incorporated.

  Next, the configuration and operation of each unit will be described in order. When the vibration data is input from the P-wave earthquake detector 10, the main control unit 11b sends the vibration data to the vibration data transmission unit 15a. The vibration data transmission unit 15a is incorporated in the transmission frame with its own position and detection time of vibration data added to the input vibration data, and connected to the network 1 via the communication unit 16 and the network 1. It transmits to all the elevator apparatuses 2b other than self.

  The vibration data receiving unit 24 receives the vibration data transmitted from the other elevator apparatus 2b via the network 1 and the communication unit 16, and transmits the vibration data to the earthquake prediction unit 25. As with the earthquake prediction unit 20 of the monitoring center 3 of the first embodiment in FIG. 1, the earthquake prediction unit 25 is a state in which vibration data is input from, for example, three elevator apparatuses 2 b located near the epicenter with respect to the same earthquake. Then, calculate (predict) the epicenter and magnitude of the earthquake. And if the judgment part 26 judges that the vibration level at the time of the earthquake wave of this earthquake reaching the installation position of the said elevator apparatus 2b is more than the regulation level of 150 Gal, it will send the instruction | command of earthquake control operation to the main control part 11b. . The main control unit 11b executes the seismic control operation 14 when the seismic control operation 14 has not yet started.

  FIG. 6 is a flowchart showing the overall operation of each elevator apparatus 2b. When the P wave seismic detector 10 in its own elevator apparatus 2b detects the P wave of the earthquake and P wave vibration data is input to the main controller 11b (step R1), the vibration data is transmitted via the network 1. To the other elevator apparatus 2b (R2). When the vibration level of the vibration data is equal to or higher than the specified level (R3), the normal operation unit 13 is stopped and the seismic control operation unit 14 is activated (R4). When the car 5 stops at the nearest floor in the seismic control operation section 14 and a passenger in the car 5 retreats to the elevator hall on the corresponding floor, the door is closed, the elevator is stopped (R5), and inspection is performed by maintenance personnel. Transition to the wait state.

  In addition, when vibration data is input from another elevator apparatus 2b at R6, the epicenter and magnitude of the earthquake are calculated (predicted) (R7). If it is determined that the vibration level of the earthquake at the position of the elevator device 2b is (R8) and a vibration exceeding the specified level of 150 Gal occurs (R9), an instruction for an earthquake control operation is sent to the main control unit 11b. The main control unit 11b executes the seismic control operation 14 when the seismic control operation 14 has not yet started. At the present time, it is checked whether or not the seismic control operation unit 14 is in operation, and if it is not in operation (R10), the seismic control operation unit 14 is activated ((R11). ((R12)), and shifts to a state of waiting for inspection by maintenance personnel.

  And when it is in operation (S7), the P-wave seismic detector 10 of its own elevator device 2b has generated a vibration that exceeds the specified value, and the seismic control operation unit 14 is already in operation or has ended. Since the elevator is stopped, do nothing.

  In the elevator seismic control system according to the third embodiment configured as described above, a part of each elevator apparatus 2b is arranged to monitor the earthquake before the seismic wave of this earthquake arrives for an earthquake occurring far away. Seismic control operation will be carried out according to the command from. This earthquake control operation start time is actually an earthquake.

  Furthermore, since the earthquake prediction function is incorporated in each elevator apparatus 2b itself for the epicenter value and the magnitude of the earthquake that has occurred, it is not necessary to install a separate monitoring center.

(Fourth embodiment)
FIG. 7 is a schematic diagram showing a schematic configuration of an elevator earthquake control system according to the fourth embodiment of the present invention.

The earthquake prediction unit 25a calculates the epicenter and magnitude of the earthquake in a state where vibration data is input from the three elevator apparatuses 2c located close to the epicenter. Next, the seismogenic area and the earthquake scale in a wide area are predicted from the calculated epicenter and magnitude.

  And the determination part 26a determines each elevator apparatus 2a, 2c of the position predicted that the vibration more than the regulation level of 150 Gal mentioned above will arise based on this earthquake prediction result. And the control operation instruction | indication part 27 transmits the execution command of an earthquake control operation via the communication part 16 and the network 1 to each determined elevator apparatus 2a, 2c. In the case where the elevator apparatus 2c is located at a position where it is predicted that the vibration of the own elevator apparatus 2c will exceed the specified level, the control operation instruction section 27 sends the seismic control operation to the main control section 11c of the own elevator apparatus 2c.

Next, from the calculated epicenter of the earthquake and the magnitude of the earthquake, the seismogenic area and the magnitude of the earthquake in a wide area are predicted (P7). Based on this earthquake prediction result, each elevator apparatus 2a, 2c at a position where it is predicted that vibration of a specified level or more will occur is determined (P8), and an execution command for the earthquake control operation is determined to each of the determined elevator apparatuses 2a, 2c. Is transmitted (P9). When it is predicted that the vibration of the elevator apparatus 2c exceeding the specified level will occur (P10, P11), if the control operation is not already being executed (P12), the control operation is executed (P13). After the operation is completed, the door is closed, the elevator is stopped (P14), and the state shifts to a state of waiting for inspection by maintenance personnel.
