Description

  Embodiments described herein relate generally to an elevator apparatus that performs control operation during a disaster.

  If an earthquake occurs in the building where the elevator is installed, the elevator switches from normal operation to control operation, and the car moving in the hoistway stops at the nearest floor. Also, in the event of an earthquake, when an abnormality occurs on the way to the nearest floor, a method is known in which the traveling direction of the car is reversed and landed on the nearest floor opposite to the traveling direction. . Also, there is a known method of continuing evacuation activities without stopping the floor where the fire has been confirmed in the event of a fire.

JP 2007-84167 A No. CN101014522 published in China

  However, when an earthquake and a fire occur at the same time, seismic control operation is given priority, and the car stops at the nearest floor, so it cannot necessarily move to the evacuation floor. As a result, when an earthquake and a fire occur simultaneously, there is a possibility that the user is left in the building.

  Also, if a fire has occurred even after the earthquake has stopped, diagnostic operation cannot be performed and normal operation cannot be resumed. Even if a fire does not occur and diagnostic operation can be performed, normal operation is not performed if an abnormality is found by the diagnostic operation.

  Accordingly, there is a need for efficient evacuation guidance activities by elevators in the event of an earthquake and fire.

  An elevator apparatus according to an embodiment includes a hoistway provided in a building, an elevator operation control means for controlling the operation of the car, and a disaster detection for detecting occurrence of an earthquake and a fire. The elevator operation control means moves the car to the nearest floor when a fire and an earthquake are detected by the disaster detection means, and then the elevator user in the building. If it is determined that the car can be safely moved to the floor where the remaining user is present, the car can be moved to the floor where the remaining user is present. It is characterized by moving.

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

(First embodiment)
FIG. 1 is a schematic configuration diagram illustrating an elevator apparatus according to the first embodiment.

  In the figure, reference numeral 1 denotes a hoistway installed in a building, and a landing call registration device 2 is provided on each floor of the hoistway 1. Furthermore, a fire detection sensor 3 for detecting a fire is attached to each floor of the hoistway 1. An earthquake detection sensor 4 for detecting an earthquake is installed in the hoistway 1.

  A hoisting machine 5 is provided in the hoistway 1. A rope 6 is wound around the winder 5. One end of the rope 6 is connected to the car 7. The other end of the rope 6 is connected to the counterweight 8. When the rope 6 is driven by the hoisting machine 5, the car 7 and the counterweight 8 are moved up and down in opposite directions in the hoistway 1 (slip type). A destination floor call registration device 9 is provided in the car 7. A car position detection sensor 10 for detecting the position of the car 7 is provided at a location corresponding to each floor in the hoistway 1.

  The hall call registration device 2, the fire detection sensor 3, and the earthquake detection sensor 4 are connected via a transmission line 11 to an elevator operation control device 12 that controls the operation of the elevator. The car 7 is also connected to the elevator operation control device 12 via the transmission line 11. The elevator operation control device 12 can control the operation of the car 7 based on the landing call registration device 2, the fire detection sensor 3, the earthquake detection sensor 4, the destination floor call registration device 9, and the like. A weight sensor (not shown) for measuring the loaded weight of the car 7 is also connected to the elevator operation control device 12.

  The elevator operation control device 12 controls the operation of the car 7 according to the input status of the landing call registration device 2 and the destination floor call registration device 9. At this time, the elevator operation control device 12 monitors the fire detection sensor 3 and the earthquake detection sensor 4, and always controls the operation of the car 7 based on the latest information.

  When the occurrence of a disaster is detected from the fire detection sensor 3, the earthquake detection sensor 4, or both of these sensors 3, 4, the elevator operation control device 12 performs appropriate control operation on the car 7. During the control operation, the registration operation by the destination floor call registration device 9 becomes invalid, and the destination cannot be determined freely during the control operation.

  When the occurrence of a disaster is detected from only one of the fire detection sensor 3 and the earthquake detection sensor 4, a known control operation is performed.

  On the other hand, when the occurrence of a disaster is detected from both the fire detection sensor 3 and the earthquake detection sensor 4, the control operation of the embodiment is performed.

  Here, when detecting the occurrence of a fire and an earthquake, the conventional elevator apparatus moves a car on which a passenger is riding to the nearest floor. Due to a fire, the car stops at the nearest floor and the elevator is suspended. Therefore, even if there is a landing call from another floor after moving the car to the nearest floor, the elevator is not in operation and no response is made to the landing call.

  On the other hand, the elevator apparatus of this embodiment, when detecting the occurrence of a fire and an earthquake, moved the passenger car 7 on which the passenger is riding to the nearest floor, and then called a landing from another floor Occasionally, while performing a diagnostic operation (monitoring the state of the car 7, the state of the hoistway 1, etc.), the operation of the elevator is continued and the car 7 is directed to the other floor (destination). If there is no abnormality, the car 7 arrives at the destination while stopping each floor. When there is an abnormality (for example, the door does not open), the car 7 travels to the destination at a reduced speed without stopping at the floor where the abnormality is present.

  In this way, even in the event of a fire or earthquake, the operation will continue with diagnostic operation, and if an abnormality is detected in the diagnostic operation, the control range will be controlled according to the extent of the abnormality. By using the elevator operation control device 12, it is possible to improve the efficiency of evacuation guidance activities by the elevator when an earthquake and a fire occur simultaneously.

  Hereinafter, the control operation of the embodiment will be described in more detail with reference to the flowcharts of FIGS. 2 and 3.

  The elevator operation control device 12 determines whether a fire and an earthquake are detected based on the outputs of the fire detection sensor 3 and the earthquake detection sensor 4 (step S1).

  When the earthquake and the fire are not detected in the determination in step S1 (No), the elevator operation control device 12 continues the normal operation (step S2). However, when only an earthquake is detected, a known earthquake control operation is performed, and when only a fire is detected, a known fire control operation is performed.

  If a fire and an earthquake are detected in the determination in step S1 (Yes), the elevator operation control device 12 moves the car 7 to the nearest floor (step S3). At this time, if a passenger is in the car 7, the passenger gets off at the nearest floor.

  Next, the car 7 is moved to the evacuation floor 13 while performing the diagnostic operation (step S4). At this time, there are no passengers in the car 7.

  Diagnosis operation is a series of operations for automatic recovery, such as checking the brake of the hoisting machine 5, checking the abnormality of the rope 6 and the counterweight 8, and stopping operation at each floor. Further, the elevator operation control device 12 does not perform any special operation control other than the diagnostic operation until the car 7 arrives at the evacuation floor 13.

  Next, when the car 7 arrives at the evacuation floor 13, the elevator operation control device 12 determines whether or not there is a landing call (hereinafter simply referred to as a call) created by the landing call registration device 2 (step). S5).

  In the determination in step S5, if no call is made after a certain period of time (No), the elevator operation control device 12 determines that there are no elevator users remaining in the building and evacuates from the nearest floor. The normal diagnostic operation is continued in the remaining section excluding the section up to the floor (step S6), and the control operation ends.

  On the other hand, if there is a call in the determination of step S5 (Yes), the elevator operation control device 12 is already in the diagnostic operation during the section from the evacuation floor 13 to the floor with the call (destination). Judgment is made as to whether or not there is a section (section where diagnosis operation has been completed) (step S7). Since the section where the diagnostic operation has been completed is a section where the car 7 can pass through the diagnostic driving, it is assumed that the section is safe for traveling on the cheap car 7.

  If it is determined in step S7 that there is no section for which diagnostic operation has been completed (Yes), the elevator operation control device 12 causes the car 7 to travel from the evacuation floor 13 toward the destination while performing the diagnostic operation (step S8). .

  The elevator operation control device 12 determines whether there is no abnormality before the car 7 arrives at the destination based on the information (diagnosis result) acquired by the diagnostic operation (step S9).

  If there is an abnormality in the determination in step S9 (Yes), the elevator operation control device 12 determines whether there is no problem in traveling and safe traveling is possible (step S10).

  If it is determined in step S10 that safe traveling is not possible (No), the elevator operation control device 12 stops the elevator (step S11). In this case, the operation of the elevator is not continued for the user who is left in the building.

  On the other hand, if it is determined in step S10 that safe travel is possible (Yes), the travel is continued without stopping at the floor where the abnormality is detected (step S12).

  If there is no abnormality in the determination in step S9 (No), the vehicle continues to travel while stopping on the floor (step S12).

  Next, the elevator operation control device 12 determines whether or not the car 7 has arrived at the destination floor (step S13).

  If it is determined in step S13 that the vehicle arrives at the destination floor (Yes), the elevator operation control device 12 takes the elevator 7 from the destination to the evacuation floor 13 when the elevator user gets on the car 7 that has arrived at the destination. Is moved (step S14). It can be understood from the output of the weight sensor (increase in the weight of the car 7) that the user of the elevator got on the car 7.

  At this time, the section where there is no abnormality travels at the rated speed, and the section where there is an abnormality but allows safe traveling travels at a low speed.

  Even if an earthquake and a fire occur at the same time, the diagnostic operation is executed, and even if a part of the abnormality is discovered, if it does not hinder driving, normally even if the predetermined stop condition is satisfied By continuing the driving, it is possible to realize the efficiency of the evacuation guidance activities.

  After arriving at the evacuation floor 13, passengers in the car 7 evacuate and the car 7 becomes empty.

  Next, the elevator operation control device 12 determines whether or not there is a call (step S15).

  If it is determined in step S15 that no call has been made after a certain period of time has elapsed (Yes), the elevator operation control device 12 determines that there are no elevator users remaining in the building, and ends the control operation. . If there is a section in which the diagnostic operation is not completed, the control operation is terminated after the diagnostic operation is completed.

  On the other hand, if it is determined in step S15 that there is a call before a predetermined time has elapsed (No), the process returns to step S7.

  The above is a case in which the determination in step S7 is Yes, but if the determination in step S7 is No, that is, if there is a section that has undergone a diagnostic operation, the elevator operation control device 12 performs the diagnostic operation in all sections. It is determined whether or not it has been completed (step S16).

  If the diagnosis operation has been completed in all sections in the determination of step S16 (Yes), the vehicle travels to the destination floor at the rated speed (step S17). Thereafter, the process proceeds to step S14.

  On the other hand, if it is determined in step S16 that the diagnosis operation has not been completed in all the sections (No), the car 7 is driven at the rated speed in the section in which the diagnosis operation is completed (the diagnosis operation completed section), and the diagnosis operation is performed. In the unfinished section (undiagnosed operation section), the car 7 is caused to travel while performing the diagnosis operation (step S18).

  FIG. 4 shows a specific example when diagnosis operation is not completed in all sections.

  FIG. 4A shows an example in which a non-diagnostic driving section follows a diagnostic driving completed section.

  FIG. 4B shows an example in which a diagnostic operation completed section follows an undiagnosed operation section.

  FIG. 4C shows an example in which the non-diagnostic operation section continues after the diagnosis operation completed section, and then the diagnosis operation completed section continues.

  FIG. 4D shows an example in which a non-diagnostic operation section is followed by a diagnostic operation complete section, and then an undiagnosed operation section.

  The elevator operation control device 12 determines whether or not there is an abnormality in the undiagnosed operation section (step S19).

  If there is an abnormality in the determination in step S19 (Yes), the elevator operation control device 12 determines whether there is no problem in traveling and safe traveling is possible (step S20).

  If it is determined in step S20 that safe traveling is not possible (No), the elevator operation control device 12 stops the elevator (step S21). In this case, the operation of the elevator is not continued for the user who is left in the building.

  On the other hand, if it is determined in step S20 that safe traveling is possible (Yes), the vehicle travels in the undiagnosed operation section without stopping on the floor where the abnormality is detected (step S22).

  Moreover, when there is no abnormality in determination of step S19 (No), it travels in the said non-diagnosis area, stopping at a floor (step S22).

  Next, the elevator operation control device 12 determines whether or not there is an undiagnosed zone operation up to the destination floor (step S23).

  If it is determined in step S23 that there is an undiagnosed zone operation remaining (No), the process returns to step S18.

  On the other hand, if it is determined in step S23 that there is no undiagnosed section operation remaining (Yes), the process proceeds to step S14.

  FIG. 5 is a transition diagram of the elevator car for specifically explaining the control operation method of the present embodiment. FIG. 5 shows a building having a first basement floor (B1) and six floors above ground (1F to 6F). 1F is described as an evacuation floor.

  FIG. 5A shows a state corresponding to a call made by the landing call device on the third floor after arrival at the evacuation floor (1F). First, it is confirmed whether the car has already passed through diagnostic driving until the 3rd floor where the call is made (step S7).

  At this point, it is assumed that no section has passed. In this case, it responds to the call of 3F while executing the diagnostic operation (step S8). The car travels from 1F to 3F at the low speed specified in the diagnostic operation. Here, it is assumed that, as a result of the diagnostic operation, between 1F and 3F is a safe section where there is no failure, and the car arrives on the 3rd floor (Yes in step S13).

  FIG. 5B shows how the user gets into the car that has arrived on the third floor, and the car moves to the evacuation floor (step S14). Since 1F-3F is a safe section without any obstacles, the car runs at the rated speed from 3F to 1F. In addition, you may drive | work at the low speed prescribed | regulated by diagnostic driving | operation.

  FIG. 5C shows a state where the passenger car has arrived at the evacuation floor (1F) and the evacuation of passengers has been completed.

  FIG. 5D shows a state corresponding to a call created by the landing call device at 6F after passenger evacuation is completed. It is confirmed whether or not the car has already passed through the diagnostic operation until 6F where the call has been made (step S7).

  In this time, the section from 1F to 3F has already passed through the diagnosis operation, so the car travels from 1F to 3F at the rated speed (step S18). In the section from 3F to 6F, the car does not pass through the diagnosis operation, so the car travels from 3F to 6F while performing the diagnosis operation at a low speed.

  FIG. 5E shows a state in which a failure is detected in the diagnostic operation on the way from 3F to 6F (step S19). Here, it is assumed that the elevator operation control device determines that a failure has occurred at 5F based on the output signal (abnormal signal) of the car position detection sensor at 5F. In this case, the elevator operation control device 12 prohibits the stop of the car at 5F and the door closing operation at 5F. The elevator operation control device 12 further prohibits call registration using the 5F landing call button. Therefore, 5F is a non-stop floor (a floor where the elevator service is not performed).

  In FIG. 5 (f), even when a failure is detected in the diagnostic driving on the way from 3F to 6F, the car is driven to 6F (step S22), and the user gets into the car that has arrived at 6F. It shows a state. 5F is non-stop, but it can pass, so if an abnormality is found, it will not be stopped, and the car will continue to run until 6F, although there are restrictions such as reducing the speed. .

  Thereafter, the elevator operation control apparatus lowers the 6F passenger car to the 1F evacuation floor and evacuates passengers. When the passenger evacuation is completed, the state returns to the state of FIG.

  Thus, according to the present embodiment, when the earthquake detection and the fire detection occur at the same time, the operation is not stopped after stopping to the nearest floor (conventional), and the operation is performed while performing the diagnostic operation for the landing call. Even if there are some abnormalities, driving safe sections can contribute to evacuation of passengers, so that the efficiency of evacuation guidance activities by elevators can be improved.

(Second Embodiment)
FIG. 6 is a schematic configuration diagram illustrating an elevator apparatus according to the second embodiment.

  The present embodiment is different from the first embodiment in that it further includes an information display device 41 and a sound generation device 42 controlled by the elevator operation control device 12.

  The information display device 41 and the sound generation device 42 are connected to the elevator operation control device 12 via the transmission line 11.

  The information display device 41 and the sound generation device 42 are devices for informing the user of information such as a non-stop floor, an evacuation floor, an abnormality occurrence floor, a permanent failure, and a safety floor in real time. This is realized by using a display or a speaker.

  Hereinafter, the information display device 41 and the sound generation device 42 will be specifically described.

  If the elevator operation control device 12 determines that the 5F door cannot be opened and 5F falls into a non-stop floor, the elevator operation control device 12 does not accept the 5F call.

  In this case, the elevator operation control device 12 displays the display information that combines the evacuation floor and the floor determined to be dangerous based on the information from the fire detection sensor 3 that does not stop at 5F. 41 is output.

  In response to a command from the elevator operation control device 12, the information display device 41 displays, for example, a message as shown in FIG. 7 on the display as the display information.

  Further, the elevator operation control device 12 outputs an announcement command to the sound generation device 42 in order to make an announcement of the dangerous floor and the evacuation floor not to stop at 5F.

  The sound generation device 42 that has received the instruction announces, for example, “Elevators cannot be used on the fifth floor. Use from other floors or evacuate using the stairs to the first floor.” To notify the user at the landing.

  Further, when a permanent failure occurs due to a fire or the like, the elevator operation control device 12 stops the function of the hall call registration device 2 for all floors.

  In this case, the elevator operation control device 12 outputs to the information display device 41 that the information display device 41 cannot use the elevator. At that time, the elevator operation control device 12 may output the evacuation floor to the information display device 41 at the same time.

  In response to a command from the elevator operation control device 12, the information display device 41 displays, for example, a message as shown in FIG. 8 on the display in order to notify that the elevator cannot be used.

  Furthermore, the elevator operation control device 12 outputs an announcement command to the sound generation device 42 in order to announce that it will not stop at 5F and that the elevator cannot be used.

  Upon receiving the command, the sound generator 42 makes an announcement, such as “Currently, the elevator cannot be used. Please evacuate to the outside of the building promptly”, and informs the user at the landing.

  Thus, according to the present embodiment, since the information display device 41 and the sound generation device 42 controlled by the elevator operation control device 12 are provided, a fire and an earthquake are detected by the fire detection sensor 3 and the earthquake detection sensor 4. In such a case, it is possible to notify the user at the elevator platform in real time that the control operation with operation restrictions such as the non-stop floor, the evacuation floor, and the abnormality occurrence floor is being executed. As a result, evacuation guidance activities can be promoted more efficiently. In addition, the same effects as those of the first embodiment can be obtained.

(Third embodiment)
FIG. 9 is a schematic configuration diagram illustrating an elevator apparatus according to the third embodiment.

  The present embodiment is different from the first embodiment in that an evacuation floor 13A is further provided in addition to the evacuation floor 13. Hereinafter, the evacuation floor 13 is referred to as a first evacuation floor 13 and the evacuation floor 13A is referred to as a second evacuation floor 13A.

  FIG. 10 is a flowchart for explaining the control operation method of the present embodiment.

  The control operation method of this embodiment differs from that of the first embodiment in that two judgments (steps S31 and S32) and one process (step S33) are added, and two judgments ( With the addition of steps S31 and S32), step S4 is changed to two steps S4a and Sb. Hereinafter, differences from the first embodiment will be further described.

  After step S3, the elevator operation control device 12 determines whether the first evacuation floor 13 is dangerous based on information output from the fire detection sensor 3 installed on each floor (step S31).

  If it is determined in step S31 that the first evacuation floor 13 is not dangerous (No), the car 7 is moved to the first evacuation floor 13 while performing the diagnostic operation (step S4a).

  Then, it progresses to step S5 and the control operation similar to 1st Embodiment is performed. However, the evacuation floor in step S14 is read as the first evacuation floor.

  On the other hand, if it is determined in step S31 that the first evacuation floor 13 is dangerous (Yes), the elevator operation control device 12 determines whether the second evacuation floor 13A is dangerous or not. A similar method is used for determination (step S32).

  If it is determined in step S32 that the second evacuation floor 13A is not dangerous (No), the car 7 is moved to the second evacuation floor 13A while performing the diagnostic operation (step S4b).

  Then, it progresses to step S5 and the control operation similar to 1st Embodiment is performed. However, the evacuation floor in step S14 is read as the second evacuation floor.

  On the other hand, if it is determined in step S32 that the second evacuation floor 13A is dangerous (Yes), the elevator operation control device 12 determines the safest distance from the evacuation floor (the first evacuation floor 13 or the second evacuation floor 13A). The car 7 is moved to the boarding floor (step S33). At this time, the car 7 may be moved while performing the diagnostic operation.

  Thus, according to the present embodiment, the elevator users can be evacuated more safely by switching between the two evacuation floors so as not to guide the evacuation floor determined to be dangerous based on the damage situation of the building. It can be guided finger. In addition, the same effects as those of the first embodiment can be obtained.

  In the present embodiment, two evacuation floors are switched, but three or more evacuation floors may be switched.

(Fourth embodiment)
FIG. 11 is a schematic configuration diagram illustrating an elevator apparatus according to the fourth embodiment.

  This embodiment is different from the first to third embodiments in that remote communication is possible between the elevator operation control device 12 and the elevator monitoring center 52 for monitoring the operation state of the elevator, That is, the elevator operation control device 12 can transmit various information related to the elevator to the elevator monitoring center 52 in real time. This embodiment can be applied to any of the first to third embodiments.

  In the present embodiment, the elevator operation control device 12 is connected to the elevator monitoring center 52 via the communication line 51 in order to enable transmission of various information related to the elevator. The communication line 51 may be either a public line or a dedicated line, or may be a combination of both.

  The various types of information related to the elevator include information related to a car when a fire and an earthquake are detected. For example, there are presence / absence of a user confined in the car, presence / absence of a user who cannot evacuate from the landing due to a failure, and a driving state of the car.

  Specifically, for example, as described in the first embodiment, when an abnormal signal is detected from the car position detection sensor of 5F and 5F is determined to be abnormal (FIG. 5 (e)), the elevator The operation control device 12 transmits an abnormal situation (information) that the 5F door cannot be opened to the elevator monitoring center 52 by remote communication in real time.

  Further, when the elevator operation control device 12 determines that there is a dangerous floor due to a fire based on the information output from the fire detection sensor 3, the elevator operation control device 12 determines that the evacuation floor currently being guided ( Information) and call status (information) are transmitted to the elevator monitoring center 52 in real time by remote communication.

  On the other hand, the elevator monitoring center 52 can smoothly give action instructions to the elevator maintenance staff based on the information received from the elevator operation control device 12, and the response system in the event of a disaster in the building and the elevator maintenance staff It will be possible to enhance cooperation.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
