Description

  The present invention relates to a control device and an control method for optimally operating an elevator when receiving an earthquake early warning in an elevator provided with two cars that move up and down independently in a hoistway.

  In recent years, emergency earthquake alerts obtained from seismic observation networks spread throughout Japan have been delivered to various locations using the Internet and satellite communications immediately after the earthquake has occurred. Various initiatives and proposals have been made, such as taking effective measures against the earthquake. For example, as a prior art of an elevator using the above-mentioned earthquake early warning, it is received by receiving an earthquake early warning via a satellite communication station, a ground antenna for satellite, a satellite, etc. by a receiving antenna provided in an elevator installation building. Based on the urgent earthquake early warning, there has been proposed one that senses an earthquake earlier than the seismometer installed in the building and stops the elevator on the nearest floor (see Patent Document 1).

And a control means for determining whether or not the rescue operation is completed before reaching, and continuing the rescue operation if the rescue operation can be completed.

  An elevator control method according to the present invention is an elevator control method provided with two cars that move up and down independently in a hoistway, the step of detecting confinement occurring in one car, and after the occurrence of confinement , Starting a rescue operation to rescue passengers in one car to the other car capable of ascending and descending, receiving an emergency earthquake bulletin delivered from the outside after the earthquake occurs, and emergency earthquake bulletin during rescue operation If it is determined that the rescue operation will be completed before the main motion of the earthquake arrives, and the rescue operation is determined to be completed before the main motion of the earthquake reaches And a step of continuing the operation.

  According to the present invention, in an elevator provided with two cars that move up and down independently in the hoistway, an emergency earthquake warning is issued when a passenger is rescued from one car in which confinement has occurred to the other car that can be raised and lowered. Even when it is received, the elevator can be optimally operated according to the situation.

  In order to explain the present invention in more detail, it will be described with reference to the accompanying drawings. In addition, in each figure, the same code | symbol is attached | subjected to the part which is the same or it corresponds, The duplication description is simplified or abbreviate | omitted suitably.

Embodiment 1 FIG.
FIG. 1 is a front view showing an elevator apparatus according to Embodiment 1 of the present invention, and FIG. 2 is a plan view showing the elevator apparatus according to Embodiment 1 of the present invention. FIG. 2 is a view taken along the line CC in FIG. First, the configuration of the elevator apparatus will be described with reference to FIGS. 1 and 2.

  Reference numeral 1 denotes an elevator hoistway, and 2 and 3 denote two cars that move up and down independently in one hoistway 1. The cars 2 and 3 have a configuration that can be arranged side by side in the hoistway 1. For example, when confinement occurs in one of the cars 2, the other car 3 that can be lifted and lowered in the hoistway 1 is placed next to the car 2 and stopped, and then the rescue passage is between the cars 2 and 3. The passengers trapped in one car 2 are moved to the other car 3.

  In the cars 2 and 3, in order to enable the rescue operation as described above, rescue openings are formed in the side walls 4 and 5 that are opposed to each other in plan view so that a person can go in and out of the cars 2 and 3. . Each rescue outlet is closed by rescue doors 6 and 7 provided in the car 2 and the car 3, respectively, to ensure safety during normal operation of the elevator, and is opened only when necessary. Reference numeral 8 denotes a rescue plate that is bridged between the cars 2 and 3 when the passenger is rescued using the rescue port. That is, when confinement occurs in one car 2, the passenger in the car 2 moves across the rescue plate 8 to the other car 3 that can be raised and lowered. The rescue plate 8 is folded so as to be folded into one or both of the cars 2 and 3 during normal operation of the elevator and stored so as not to hinder the lifting and lowering operations of the cars 2 and 3 and the like.

  Further, in the cars 2 and 3, notification means 9 and 10, rescue buttons 11 and 12, and return buttons 13 and 14 are provided, respectively. The notification means 9 and 10 are means for notifying passengers in the cars 2 and 3 of various types of information. For example, an in-car display that provides information to the passengers by letters or information by voice It is comprised by the announcement apparatus etc. which do.

  The rescue buttons 11 and 12 are operated to automatically dock the cars 2 and 3 when confinement occurs. For example, when confinement occurs in one of the cars 2, the car 3 automatically starts running when the rescue button 12 in the other car 3 that can be moved up and down is pressed, and the car 3 stops the car 2. Automatically stops at the position (height). The return buttons 13 and 14 are operated in order to return the elevator car that can be raised and lowered to the nearest floor or a predetermined return floor after the passenger is moved to the car that can be raised and lowered due to confinement. For example, after the passenger is moved from one car 2 in which confinement has occurred to the other car 3 that can be raised and lowered, the return button 14 in the car 3 is pressed, whereby the car 3 starts to travel, and the car 3 Automatically returns to the nearest floor or a predetermined return floor.

  15 and 16 are counterweights, 17 and 18 are a pair of car guide rails, 19 and 20 are elevator landings, 21 and 22 are landing door devices, and 23 is between the lifting range of the car 2 and the lifting range of the car 3. Is an intermediate beam. 24 is a hoisting machine that moves the car 2 up and down by suspending a main rope 25 that suspends the car 2 in a fishing bottle manner, and 26 is a hoisting machine that raises and lowers the car 3 by a main rope 27 that suspends the car 3 in a fishing bottle manner. The hoisting machine to be operated, 28 is the equipment in the hoisting machine 24 and the car 2, etc., the control panel (control means) that controls the entire elevator A, 29 is the equipment in the hoisting machine 26 and the car 3 And a control panel (control means) that controls the entire control of the other elevator B.

  Reference numeral 30 denotes a receiving device for receiving an emergency earthquake bulletin distributed from the Japan Meteorological Agency 31 or the like immediately after the occurrence of the earthquake. The information on the earthquake early warning received from the outside by the receiving device 30 is processed by the processing device 32. Then, the predicted seismic intensity of the shaking caused by the main motion of the earthquake (S wave) and the expected time for the main motion to reach (main motion predicted arrival time) are output from the processing device 32 to each of the control panels 28 and 29. The

  Next, based on FIG. 3, the structure of the control apparatus of an elevator is demonstrated. FIG. 3 is a block diagram showing an elevator control apparatus according to Embodiment 1 of the present invention. The control panel 28 of the elevator A and the control panel 29 of the elevator B have the same configuration corresponding to each elevator. Therefore, only the configuration of the control panel 28 will be described below, and the description of the configuration of the control panel 29 will be omitted.

  In FIG. 3, 33 is energized (ON) when the rescue button 11 is pressed, and a rescue switch 34 outputs a rescue signal to the control panel 28, and 34 is energized (ON) when the return button 13 is pressed. The return switch outputs a return signal to the control panel 28. In addition, 35 is a rescue switch corresponding to the elevator B, and 36 is a return switch corresponding to the elevator B.

  Reference numerals 37 and 38 denote rescue door switches. The rescue door switch 37 is turned on / off based on the opening / closing of the rescue door 6. That is, the rescue door switch 37 is energized (ON) when the rescue door 6 is opened, and outputs an open signal to the control panels 28 and 29. Further, the rescue door 6 is closed (OFF) when it is closed. The rescue door switch 38 is turned on / off based on the opening / closing of the rescue door 7. That is, the rescue door switch 38 is energized (ON) when the rescue door 7 is opened, outputs an open signal to the control panels 28 and 29, and is deactivated when the rescue door 7 is closed ( OFF). Reference numeral 39 denotes a rescue plate switch that is energized (ON) when the rescue plate 8 is operated and outputs a rescue plate operation signal to the control panels 28 and 29. That is, the rescue plate switch 39 detects that the rescue plate 8 is not in a predetermined storage state, outputs a rescue plate operation signal, and is turned off (OFF) when the rescue plate 8 enters a predetermined storage state. .

  The control panel 28 that controls the overall control of the elevator A includes, for example, a signal input / output means 40, a confinement detection means 41, and a control operation determination means 42. The signal input / output means 40 takes signals output from an external device such as the processing device 32 and various switches into the control panel 28, and sends various signals from the control panel 28 to the external device such as the hoisting machine 24. It is a means for outputting. In addition, the confinement detection means 41 is a means for detecting that a passenger is confined in the car 2. For example, the confinement detection means 41 is confined based on a report from the car 2, an abnormal signal from an elevator device, or the like. To detect.

  The control operation determination means 42 is a means for determining a control operation to be performed based on an input signal to the control panel 28 and actually executing the determined control operation. For example, in the control operation determination means 42, the receiving device 30 receives the earthquake early warning, and the predicted seismic intensity and the expected arrival time of the main motion are input from the processing device 32 to the control panel 28, thereby responding to the input signal. Implement seismic control operation. For example, when confinement occurs in one of the cars 2, the rescue operation is performed manually or automatically using the other car 3 that can be moved up and down.

  In addition, the control operation determination unit 42 receives, for example, an emergency earthquake warning by the receiving device 30 during a rescue operation in which a passenger is rescued from one car 2 in which confinement has occurred to the other car 3 that can be lifted and lowered. In accordance with the rescue operation status, the elevator is controlled optimally, such as continuation of rescue operation and implementation of seismic control operation. For example, it is determined whether or not the rescue operation is completed before the main motion of the earthquake arrives. If the rescue operation can be completed, the continuation of the rescue operation is given priority over the start of the earthquake control operation. In addition, 43 is a rescue status determination means for determining the current status of the rescue operation based on the traveling state of the car 2, the open / closed status of the rescue doors 6 and 7, the operation state of the rescue plate 8, etc., and 44 is the rescue status determination means Rescue continuation determining means for determining whether or not to continue the rescue operation based on the determination result of 43.

  On the other hand, for example, when it is determined in the above determination that the rescue operation is not completed before the main movement of the earthquake arrives, the rescue operation determination unit 43 determines whether the confinement has occurred. The open / close state of the rescue door 6 is determined. Then, when the opening of the rescue door 6 is detected, the notification means 9 and 10 notify the car 2 and 3 of the expected arrival time of the main movement and continue the rescue operation. If the opening of the rescue door 6 is not detected, the rescue operation is stopped and the earthquake control operation is performed.

  As described above, the control panel 29 of the elevator B also has a configuration corresponding to the control panel 28. Therefore, in the following description, the constituent elements in the control panel 29 will be described by adding b to the reference numerals of the constituent elements in the control panel 28. That is, the control panel 29 includes a signal input / output unit 40b, a confinement detection unit 41b, a control operation determination unit 42b, a rescue status determination unit 43b, and a rescue continuation determination unit 44b.

  Next, the operation of the elevator control apparatus having the above configuration will be described with reference to FIGS. FIG. 4 is a flowchart showing the operation of the elevator control apparatus according to Embodiment 1 of the present invention, and shows an example of the rescue operation when one of the cars 2 is trapped.

  In FIG. 4, when one of the cars 2 fails in the express zone and confinement occurs, confinement is detected by the confinement detection means 41 (step S101). When confinement occurs in the car 2, the rescue button 12 in the car 3 is pushed and the rescue switch 35 is turned on to rescue the passenger in the car 2 by the car 3 that can be raised and lowered (step S102). When the rescue switch 35 is turned on, the automatic docking of the cars 2 and 3 is started (step S103), and the car 3 stops according to the stop position (height) of the car 2.

  Next, in order to move passengers in the car 2 into the car 3, the rescue doors 6 and 7 provided on the opposite side walls 4 and 5 of the cars 2 and 3 are opened, and a rescue plate 8 is placed between the cars 2 and 3. (Step S104). And the passenger in the cage | basket | car 2 is moved in the cage | basket | car 3 by making the rescue board 8 cross (step S105). After all passengers confined in the car 2 are accommodated in the car 3, the rescue plate 8 is accommodated and the rescue doors 6 and 7 are closed (step S106). When the rescue plate 8 is stored and the rescue doors 6 and 7 are closed, the rescue plate switch 39 and the rescue door switches 37 and 38 are turned off.

  Next, the rescue button 12 in the car 3 is operated to turn off the rescue switch 35, and the return button 14 is pressed to turn on the return switch 36 (step S107). The car 3 automatically returns to a predetermined return floor when the return switch 36 is turned on. Then, after the return switch 36 is turned off (step S109), the passenger escapes from the car 3 to the stop 20 on the return floor that has stopped.

  On the other hand, FIG. 5 is a flowchart showing another operation of the elevator control apparatus according to Embodiment 1 of the present invention, in which a rescue operation is performed to rescue a passenger from one car 2 in which confinement has occurred to the other car 3 that can be raised and lowered. An example of the operation when the earthquake early warning is received by the receiving device 30 is shown.

  In FIG. 5, when the earthquake early warning is received by the receiving device 30 during the rescue operation (steps S201 and S202), the control operation determination means 42b of the control panel 29 causes the rescue operation to be continued or the earthquake control operation is performed. Transition is determined. Specifically, first, it is determined whether or not the rescue of passengers in the car 2 is completed by the expected time of arrival of the main movement (step S203). In the determination in the above step S203, whether or not the rescue of the passenger is completed based on the predicted main motion arrival time based on the earthquake early warning and the current rescue operation status determined by the rescue status determination means 43b. To be judged.

  For example, when the current rescue operation state is when the car 3 is traveling toward the stop position of the car 2, the estimated traveling time required for the car 3 to reach the stop position of the car 2, and the car When the sum of the estimated rescue time required to move the passengers in the car 2 to the car 3 is within the expected main movement arrival time, it is determined that the rescue is possible. On the other hand, when the current rescue operation is stopped at the same height as the car 2, the rescue calculated based on the open / closed state of the rescue doors 6 and 7 and the operation state of the rescue plate 8. When the expected time is within the expected time for reaching the main motion, it is determined that the rescue is possible.

  Here, if it is determined in step S203 that the rescue of the passenger can be completed by the expected time of arrival of the main motion, the rescue operation is continued without performing the earthquake control operation, and the passenger is moved from the car 2 to the car 3 (Step S204).

  On the other hand, when it is determined in step S203 that the rescue of the passenger is not completed, it is determined whether or not the rescue door 6 provided in the car 2 is opened (step S205). In step S205, it is determined whether or not the rescue door 6 is opened because the operation shown in FIG. 5 is an operation when the passenger is moved from the car 2 into the car 3. That is, in such a case, the rescue doors 6 and 7 and the operation of the rescue plate 8 are performed by a rescue worker or the like who has entered the car 3. For this reason, after the car 3 is stopped, the rescue operation is performed in the order of opening the rescue door 7, operating the rescue plate 8, opening the rescue door 6, and moving the passenger. That is, when the rescue door 6 is opened, a rescue passage has already been formed between the cars 2 and 3, and the movement of the passenger has started, or the rescue passage will be completed soon and the passenger will move. It means a state that starts immediately.

  Therefore, when the opening of the rescue door 6 is detected in step S205, even if it is determined in step 203 that the rescue is not completed by the expected main movement arrival time, the notification means 9 and 10 in the cars 2 and 3 are used. The rescue operation is continued while paying attention to the estimated time of arrival of the main motion notified by (step S206). It should be noted that the notification of the expected main movement arrival time by the notification means 9 and 10 may be performed immediately after receiving the earthquake early warning or when the opening of the rescue door 6 is detected in step S205. May be. And after rescue of a passenger is completed, the rescue switch 35 is turned OFF and normal earthquake control operation is implemented (steps S207 to S209). In the above operation, it is conceivable that the main movement arrives before the car 3 stops at the nearest floor due to the seismic control operation. In such a case, measures such as stopping the car 3 in the express zone or the like are taken in accordance with the magnitude of the actually detected shaking.

  Further, when the opening of the rescue door 6 is not detected in step S205, the rescue passage is not completely formed between the cars 2 and 3, and the passengers in the car 2 remain confined. In such a case, the rescue operation is stopped in order to reliably prevent the passenger from moving between the cars 2 and 3 when the main movement is reached. That is, first, the rescue plate 8 is accommodated and the rescue door 7 is closed (step S210). Then, after the rescue switch 35 is turned off, normal seismic control operation is performed (steps S211 and S212).

  According to Embodiment 1 of the present invention, even when an emergency earthquake warning is received when a passenger is rescued from one car in which confinement has occurred to the other car that can be raised and lowered, it is matched to the situation of the rescue operation. Thus, the elevator can be optimally operated, and both the speed of rescue operation and the safety of passengers can be improved.

  In other words, even if an emergency earthquake warning is received during rescue operation, if the rescue operation is completed by the expected time of arrival of the main motion, the rescue operation will be continued and the passenger will be evacuated safely to the return floor. Can do. On the other hand, when the rescue operation is not completed by the expected time of arrival of the main motion, it is further determined to continue or stop the rescue operation based on the open / closed state of the rescue door of the cage in which the confinement has occurred. Therefore, the elevator can be operated more optimally according to the situation.

  In addition, although the above demonstrated the case where the earthquake early warning was received during the rescue operation, a fire occurred during the rescue operation, and a fire occurrence signal was transmitted from the fire detector to the control panels 28 and 29. The same operation as described above may be performed. With this configuration, the elevator can be optimally operated even in a fire.
