(First embodiment)
Drawing 1 is a figure showing typically an example of composition of an elevator control system concerning a 1st embodiment. The elevator control system 1 includes a plurality of elevators 10A and 10B and an elevator control device 30 that manages the retreat control of the plurality of elevators 10A and 10B when water is flooded. In addition, in this figure, although the elevator 10B has not shown structures other than the hoistway 11 and the control part 16, other structures are the same as that of the elevator 10A. Hereinafter, when it is not necessary to distinguish between the elevator 10A and the elevator 10B, they are collectively referred to as the elevator 10. Further, in the following embodiment, an elevator having no machine room will be described as an example. Furthermore, although two elevators 10 are shown in this figure, three or more elevators 10 may be connected to the elevator control device 30.

  The elevator 10 is installed as a means for moving between floors in buildings such as office buildings, department stores, hotels, school buildings, commercial facilities, and underground malls. The elevator 10 includes a hoistway 11 provided through each floor in the building. The elevator 10 includes a hoisting machine 12, a car 13, a counterweight 14, and a main rope 15 in the hoistway 11. A main rope 15 is stretched over the hoisting machine 12. A car 13 and a counterweight 14 are connected to both ends of the main rope 15. That is, the elevator 10 of this example is a so-called slidable elevator.

  The hoisting machine 12 raises and lowers the car 13 in the hoistway 11 by hoisting the main rope 15 that has been passed over and changing the relative position of the car 13 and the counterweight 14 in the elevating direction. The passenger car 13 gets on and off by the user and moves the user on the board to the target floor. The counterweight 14 is a weight for balancing with the car 13 and moves in the hoistway 11 in conjunction with the raising and lowering of the car 13.

  The elevator 10 includes a control unit 16 in the hoistway 11. The control unit 16 controls the entire elevator 10 provided with the control unit 16, operates the hoisting machine 12, and moves the car 13 to a designated floor. The control unit 16 is equipped with electrical appliances necessary for operating the elevator 10 or hardware such as a CPU (Central Processing Unit) and memory in computer control. The control unit 16 is connected to the elevator control device 30 via a wired or wireless network 70 that is a communication line, and can transmit and receive signal information.

  The elevator 10 includes an inundation detection unit 17 that detects inundation into the hoistway 11 in the hoistway 11. The inundation detection unit 17 is configured, for example, by a float switch that is installed in the hoistway 11 and senses inundation by being pushed up by the rise of the water surface and generating an inclination. In addition, as long as it can sense the inundation in the hoistway 11, it is not restricted to a float switch and another thing can also be used. The inundation detection unit 17 is connected to the control unit 16 by wire or wirelessly, and can transmit a detection signal indicating that the inundation has occurred.

  The elevator 10B is operated by a control unit 16 installed in a building different from the elevator 10A or in a different hoistway 11 in the same building. The configuration of the elevator 10B is the same as that of the elevator 10A.

  The elevator control device 30 is connected to the control unit 16 of each elevator 10 having a different installation position via the network 70. The network 70 may be wired or wireless. The elevator control device 30 centrally manages a plurality of elevators 10 connected via the network 70. For example, the elevator control device 30 is configured by a server device that manages each elevator 10 provided in a plurality of buildings arranged in a certain area. In this embodiment, when the elevator control device 30 receives a signal that detects inundation from a certain elevator 10, the other elevator 10 that is at a predetermined distance from the elevator 10 that has detected inundation and satisfies a predetermined height condition. A save command is transmitted to.

  FIG. 2 is a block diagram schematically illustrating an example of a functional configuration of the elevator and the elevator control device that configure the elevator control system according to the first embodiment. Here, a case where the elevator 10A detects water intrusion and an evacuation command is issued to the elevator 10B is taken as an example. The same applies to the following embodiments.

  The elevator 10 includes a control unit 16 and a flood detection unit 17. When the inundation detection unit 17 detects inundation of the elevator 10 into the hoistway 11, the inundation detection unit 17 notifies the control unit 16 of detection of inundation.

  The control unit 16 includes an elevator control unit 161, an identification information storage unit 162, an identification information transmission unit 163, and a flooded information transmission unit 164. The control unit 16 is realized by, for example, an IC (Integraded Circuit) chip or an IC tag. Since the elevator 10B has the same configuration as the elevator 10A, the functional configuration in the control unit 16 is not shown.

  The elevator control unit 161 performs elevating control of the car 13 in the elevator 10 during normal time when no flooding or the like occurs, or retreat control when the flooding detection unit 17 detects flooding. The elevator control unit 161 performs retraction control when a retraction command is received from the elevator control device 30. The evacuation control is a control process in which the car 13 is moved to a predetermined reference floor so as to be in an operation stop state.

  The identification information storage unit 162 stores identification information that uniquely identifies the elevator 10 in the elevator control system 1. The identification information storage unit 162 is configured by a nonvolatile memory such as an EEPROM (Electrically Erasable Programmable Read-Only Memory).

  The identification information transmission unit 163 transmits the identification information in the identification information storage unit 162 to the elevator control device 30 according to a predetermined communication standard via the network 70 at a predetermined cycle. For example, the identification information transmission unit 163 transmits the identification information at intervals of 1 minute, 5 minutes, or 10 minutes.

  When the inundation information transmission unit 164 receives a detection signal indicating that inundation has been detected from the inundation detection unit 17, the inundation information includes identification information in the identification information storage unit 162 and inundation detection information indicating that inundation has been detected. Information is generated and the flood information is transmitted to the elevator control device 30. The inundation information transmission unit 164 transmits the inundation information according to a predetermined communication standard with the elevator control device 30.

  Next, the elevator control device 30 will be described. As shown in FIG. 2, the elevator control device 30 includes a reception unit 31, an identification information acquisition unit 32, a management target information storage unit 33, a flooded elevator identification information acquisition unit 34, an extraction unit 35, and a horizontal position. An information storage unit 36, a horizontal position information extraction condition storage unit 37, a vertical position information storage unit 39, a vertical position information extraction condition storage unit 40, and a save command transmission unit 42 are provided.

  The receiving unit 31 receives identification information in accordance with a predetermined communication standard from the control unit 16 of each elevator 10 connected to the network 70 and inundation information including the identification information and inundation detection information.

  The identification information acquisition unit 32 acquires the identification information received by the reception unit 31 and adds the acquired identification information to the management target information in the management target information storage unit 33. For example, after receiving the identification information, the identification information acquisition unit 32 may delete the identification information from the management target information when the identification information is not received from the control unit 16 of the same elevator 10 for a predetermined time or more. .

  The management target information storage unit 33 stores management target information. The management target information is information indicating identification information of the elevator 10 that is connected to the elevator control device 30 via the network 70. The elevator 10 included in the management target information is a transmission target of the save command by the elevator control device 30.

  The flooded elevator identification information acquisition unit 34 acquires the identification information of the flooded elevator 10 from the flooded information received by the receiving unit 31 as flooded elevator identification information. In addition, the flooded elevator may be called a flooded elevator.

  The horizontal position information storage unit 36 stores horizontal position information. The horizontal position information storage unit 36 is configured by a nonvolatile memory such as an EEPROM, for example. The horizontal position information is a database that stores the identification information of the elevator 10 and the installation position in the horizontal direction in association with each other. The horizontal position information is information in which the identification information of each elevator 10 is associated with the installation position in the horizontal direction. For example, the installation position in the horizontal direction is a coordinate indicating a place where the elevator 10 is installed by latitude and longitude.

  The horizontal position information extraction condition storage unit 37 stores horizontal position information extraction conditions for extracting the horizontal position information of the elevator 10 to be evacuated when the submerged elevator identification information acquisition unit 34 acquires the submerged elevator identification information. . The horizontal position information extraction condition is associated with the identification information of each elevator 10 and the extraction condition that defines the range in the horizontal position direction where there is a possibility of flooding provided for each elevator 10. Although the extraction conditions are set for each elevator 10 here, the same extraction conditions may be set for all the elevators 10. Moreover, although the horizontal position information storage unit 36 and the horizontal position information extraction condition storage unit 37 are configured separately, when providing an extraction condition for each elevator 10, the horizontal position information is associated with the identification information of the elevator 10. The horizontal position information extraction condition may be registered.

  The vertical position information storage unit 39 stores vertical position information. The vertical position information storage unit 39 is configured by a nonvolatile memory such as an EEPROM, for example. The vertical position information is a database that stores the identification information of the elevator 10 and the installation position in the vertical direction in association with each other. The installation position in the vertical direction is a location that is a condition such as the height (above sea level) that is the installation position of the elevator 10 or the building where the elevator 10 is installed, and the topography around the position where the elevator 10 is installed. Including conditions. The location condition is used to determine whether or not to be a retreat target when it is installed in a place where it is difficult to determine whether or not it is necessary to retreat by sea level alone. In the vertical position information, the identification information of each elevator 10 is associated with the installation position in the vertical direction including the height (above sea level) of the building in which each elevator 10 is installed and the site conditions. For example, the location condition is that the elevator 10 is installed in a building in the vicinity of the river or the sea (for example, within a distance of 100 m from the river or the sea), and the elevator 10 passes through the floor facing the outside of the building. For example, the elevator 10 is installed in a building near the deepest part of the valley.

  The vertical position information extraction condition storage unit 40 defines a height condition or a location condition for extracting the elevator 10 to be evacuated when the submerged elevator identification information acquisition unit 34 acquires the submerged elevator identification information. The position information extraction condition is stored. FIG. 3 is a diagram illustrating an example of the vertical position information extraction condition according to the first embodiment. The vertical position extraction condition includes identification information of each elevator 10 and an extraction condition that defines a height condition or a site condition in the vertical position direction in which there is a possibility of inundation provided for each elevator 10. Although the extraction conditions are set for each elevator 10 here, the same extraction conditions may be set for all the elevators 10. In the figure, the vertical position information storage unit 39 and the vertical position information extraction condition storage unit 40 are configured separately. However, when an extraction condition is provided for each elevator 10, the identification information of the elevator 10 is included in the vertical position information. The vertical position information extraction condition may be registered in association with.

  In the horizontal position information, the extraction unit 35 is an elevator that satisfies the horizontal position information extraction condition based on the inundated elevator at the time of inundation, and in the vertical position information, the vertical position is based on the elevator that has been submerged at the time of inundation. Elevator identification information that satisfies the information extraction condition is extracted as identification information for the elevator to be evacuated. The extraction unit 35 includes a horizontal position information extraction unit 38 and a vertical position information extraction unit 41.

  The horizontal position information extraction unit 38 includes management target information in the management target information storage unit 33, horizontal position information in the horizontal position information storage unit 36, and horizontal position information extraction conditions in the horizontal position information extraction condition storage unit 37. Based on the above, the identification information of the elevator 10 to be evacuated is extracted. For example, the horizontal position information extraction unit 38 specifies the position of the flooded elevator identification information in the horizontal position information, and acquires the extraction condition corresponding to the flooded elevator identification information from the horizontal position information extraction condition. Next, the horizontal position information extraction unit 38 extracts the identification information of the elevator 10 corresponding to the extraction condition with reference to the flooded elevator identification information. And the horizontal position information extraction part 38 produces | generates the horizontal position extraction result which extracted the elevator 10 used as the management object from the extracted elevator 10 based on management object information. The horizontal position information extraction unit 38 passes the extracted horizontal position extraction result and the flooded elevator identification information to the vertical position information extraction unit 41.

  The vertical position information extraction unit 41 calculates the vertical position information in the vertical position information storage unit 39 and the vertical position information extraction condition storage unit 40 from the submerged elevator identification information and the horizontal position extraction result extracted by the horizontal position information extraction unit 38. Based on the vertical position information extraction condition, the identification information of the elevator 10 to be saved is extracted. For example, the vertical position information extraction unit 41 acquires the height of the flooded elevator identification information from the vertical position information, and acquires the extraction condition corresponding to the flooded elevator identification information from the vertical position information extraction condition. In addition, the vertical position information extraction unit 41 acquires a record corresponding to the identification information in the horizontal position extraction result from the vertical position information. Next, the vertical position information extraction unit 41 extracts the identification information of the elevator 10 corresponding to the vertical position information extraction condition from the acquired records. The extracted identification information of the elevator 10 becomes the identification information of the elevator 10 to be saved.

  The evacuation command transmission unit 42 transmits an evacuation command for performing an evacuation operation to the elevator 10 to be evacuated extracted by the vertical position information extraction unit 41 according to a predetermined communication standard.

  Next, operations of the elevator 10 and the elevator control device 30 in the elevator control system 1 will be described. FIG. 4 is a flowchart illustrating an example of a procedure of water intrusion detection processing in the elevator according to the first embodiment. First, the identification information transmission unit 163 of the control unit 16 of the elevator 10 acquires identification information from the identification information storage unit 162 and transmits the identification information to the elevator control device 30 via the network 70 (step S11). Next, it is determined whether the inundation detection unit 17 has detected inundation (step S12).

  When inundation is detected in step S12 (in the case of Yes in step S12), the inundation information transmission unit 164 includes the identification information acquired from the identification information storage unit 162, and inundation detection information indicating that inundation has been detected. Are generated (step S13), and the flood information is transmitted to the elevator controller 30 (step S14). Further, the elevator control unit 161 executes a predetermined evacuation process (step S15).

  Thereafter, the identification information transmission unit 163 determines whether a predetermined time has elapsed since the identification information was transmitted (step S16). If the predetermined time has not elapsed (No in step S16), the process waits until the predetermined time elapses. If the predetermined time has elapsed (in the case of Yes in step S16), the identification information transmission unit 163 acquires the identification information from the identification information storage unit 162 and identifies it to the elevator control device 30 via the network 70. Information is transmitted (step S17). Thereafter, the process returns to step S16.

  In addition, when the flooding is not detected in Step S12 (No in Step S12), the identification information transmission unit 163 determines whether a predetermined time has elapsed since the identification information was transmitted (Step S18). If the predetermined time has not elapsed (No in step S18), the process waits until the predetermined time elapses. If the predetermined time has elapsed (Yes in step S18), the process returns to step S11.

  As described above, the elevator 10 periodically transmits identification information to the elevator control device 30 to indicate that it is in a connected state with the elevator control device 30. Moreover, in the elevator 10, when inundation is detected, inundation information is transmitted and the elevator 10 is evacuated.

  FIG. 5 is a flowchart illustrating an example of a procedure of a save command transmission method in the elevator control device according to the first embodiment. First, the receiving unit 31 of the elevator control device 30 receives the identification information of the elevator 10 connected to the network 70 (step S31). Next, the identification information acquisition unit 32 registers the received identification information in the management target information (step S32).

  Thereafter, the receiving unit 31 determines whether the flood information has been received (step S33). If the inundation information has not been received (No in step S33), the process returns to step S31. Moreover, when inundation information is received (in the case of Yes in step S33), the inundation elevator identification information acquisition part 34 acquires inundation elevator identification information from inundation information (step S34), and acquires the acquired inundation elevator identification information. It is passed to the horizontal position information extraction unit 38.

  Subsequently, the horizontal position information extraction unit 38 stores the identification information of the elevator 10 corresponding to the horizontal position information extraction condition in the horizontal position information extraction condition storage unit 37 in the horizontal position information storage unit 36 based on the flooded elevator identification information. Extracted from the horizontal position information (step S35).

  FIG. 6 is a diagram schematically illustrating an example of a method for extracting an elevator corresponding to the horizontal position information extraction condition from the horizontal position information according to the first embodiment. As shown in FIG. 6, it is assumed that the elevator 10 having identification information A to F connected to the elevator control device 30 is registered in a certain area. In addition, here, a case where the elevator 10 of the identification information A detects flooding is taken as an example.

  Since the flooded elevator identification information is the identification information A, the horizontal position information extraction unit 38 acquires the position information of the identification information A from the horizontal position information and specifies the position on the map information. Further, the horizontal position information extraction unit 38 extracts the elevator 10 existing in the extraction condition “region within a radius of 10 km” corresponding to the identification information A from the horizontal position information extraction condition. Specifically, for each elevator 10 stored in the horizontal position information, the distance from the flooded identification information A to the elevator is obtained, and the elevator 10 having the obtained distance within 10 km is extracted. In FIG. 6, for the sake of convenience, the region that satisfies the horizontal position information extraction condition for the elevator 10 of the identification information A is indicated as R for convenience. As a result, the elevators 10 having the identification information B and C are extracted.

  Returning to the flowchart of FIG. 5, the horizontal position information extraction unit 38 removes the identification information that is not included in the management target information in the management target information storage unit 33 from the extracted identification information, and acquires the horizontal position extraction result. (Step S36). Then, the horizontal position information extraction unit 38 determines whether the identification information is included in the horizontal position extraction result (step S37). If the identification information is not included in the horizontal position extraction result (No in step S37), since there is no elevator 10 that transmits the save command, the save command transmission process is not performed, and the process proceeds to step S31. Processing returns.

  Further, when the identification information is included in the horizontal position extraction result (Yes in step S37), the horizontal position information extraction unit 38 sends the submerged elevator identification information and the horizontal position extraction result to the vertical position information extraction unit 41. hand over. Next, the vertical position information extraction unit 41 uses the vertical position information in the vertical position information storage unit 39 among the identification information included in the horizontal position extraction result, and uses the vertical position information in the vertical position information extraction condition storage unit 40. The identification information of the elevator 10 corresponding to the extraction condition is extracted as a save target (step S38).

  For example, a specific example will be described using an example in which the elevators 10 having the identification information B and C described above are extracted. Since the submerged elevator identification information is the identification information A, the vertical position information extraction unit 41 acquires the height of the identification information A from the vertical position information, and the extraction condition (high) corresponding to the identification information A from the vertical position information extraction condition. Satisfaction conditions and location conditions). Further, the vertical position information extraction unit 41 acquires the installation position (height and location conditions) in the vertical direction corresponding to the identification information B and C that are the horizontal position extraction results.

  As for the extraction conditions, referring to FIG. 3, (a) the location is set at a height of 1 m or more and 10 m or less from the vertical position information of the flooded elevator, or (b) the location is located near the river or the sea It is. Here, the height of the elevator 10 of the identification information A is 3 m, the height of the elevator 10 of the identification information B is 15 m, the location condition is “near the river”, and the elevator of the identification information C It is assumed that the height of 10 is registered in the vertical position information as 5 m. Referring to the vertical position information, the height of the elevator 10 of the identification information B is 15 m, and the difference from the height (3 m) of the elevator 10 of the identification information A is 12 m, so the condition (A) is not satisfied. However, since the location condition of the elevator of the identification information B is “near the river”, the condition (b) is satisfied. Therefore, the identification information B is extracted as a save target.

  Moreover, since the height of the elevator 10 of the identification information C in the vertical position information is 5 m, and the difference from the height of the elevator 10 of the identification information A is 2 m, the condition (A) is satisfied. Therefore, the identification information C is extracted as a save target. As a result, the retreat target is the elevator 10 with the identification information B and C.

  Thereafter, the vertical position information extraction unit 41 determines whether identification information is included in the save target (step S39). If the identification information is not included in the evacuation target (No in step S39), the elevator 10 that transmits the evacuation instruction does not exist, and therefore the evacuation instruction transmission process is not performed, and the process proceeds to step S31. Return.

  When the save command includes identification information (Yes in step S39), the vertical position information extraction unit 41 passes the save target identification information to the save command transmission unit. Next, the save command transmission unit 42 transmits a save command to the control unit 16 of the elevator 10 that is the save target based on the identification information of the save target (step S40). Thereby, the control unit 16 of the elevator 10 to be saved receives the save command and executes the save process. Thereafter, the process returns to step S31.

  In the above description, the case where the flooding detection unit 17 of the elevator 10 detects flooding transmits the flooding information including the identification information and the flooding detection information to the elevator control device 30. However, the inundation information may be periodically transmitted from the control unit 16 of the elevator 10 to the elevator control device 30. In this case, the identification information transmitted periodically and the inundation information transmitted when inundation is detected are integrated. That is, the inundation information includes identification information and inundation detection information, and the inundation information is periodically transmitted from the control unit 16 of the elevator 10 to the elevator control device 30.

  Further, in the above description, when inundation is detected by the inundation detection unit 17 of the elevator 10, the inundation information is transmitted to the elevator control device 30, and an evacuation command is issued from the elevator control device 30 to the evacuation target elevator 10. It was. The save command transmission process when inundation is detected is not limited to this example. Below, two modifications are shown.

  In the first modified example, the inundation into the hoistway 11 is allowed to a predetermined depth, and when the inundation depth is deeper than the predetermined depth, an evacuation command is transmitted. In this case, the inundation detection unit 17 includes a sensor such as a water level sensor that can detect the inundation depth, and notifies the inundation information transmission unit 164 of the inundation depth. The inundation information transmission unit 164 periodically generates inundation information including the inundation depth and the identification information of the elevator 10 when inundation is detected, and transmits the inundation information to the elevator control device 30. Thus, in the 1st modification, control part 16 of elevator 10 transmits inundation information, even after inundation is detected.

  The flooded elevator identification information acquisition unit 34 of the elevator control device 30 acquires the flooded elevator identification information and the flooded depth from the received flooded information, and the level of the flooded in which the flooded depth is set in a stepwise manner in advance. Whether or not to execute the save instruction transmission process is determined according to whether it belongs to. For example, the water level is set to a first level up to 2 cm and a second level of 2 cm or more. Then, the submerged elevator identification information acquisition unit 34 does not notify the horizontal position information extraction unit 38 of the acquired submerged elevator identification information when the acquired submersion depth is at the first level. That is, in this case, the save command is not transmitted. On the other hand, the submerged elevator identification information acquisition unit 34 notifies the horizontal position information extraction unit 38 of the acquired submerged elevator identification information when the acquired submergence depth is at the second level. That is, in this case, a save command is transmitted. The boundary value between the first level and the second level can be arbitrarily set according to the installation position of the elevator 10, for example.

  In the second modified example, when the inundation depth continues to increase by looking at the change of the inundation depth in a predetermined period after the inundation into the hoistway 11 starts, the evacuation command is transmitted. In this case, the inundation detection unit 17 includes a sensor such as a water level sensor that can detect the inundation depth, and notifies the inundation information transmission unit 164 of the inundation depth. The inundation information transmission unit 164 periodically generates inundation information including the inundation depth and the identification information of the elevator 10 when inundation is detected, and transmits the inundation information to the elevator control device 30. As described above, also in the second modification example, the control unit 16 of the elevator 10 transmits the inundation information even after the inundation is detected.

  The flooded elevator identification information acquisition unit 34 of the elevator control device 30 acquires the flooded elevator identification information and the flooded depth from the received flooded information, and until the predetermined period elapses after the first flooded information is received. The horizontal position information extraction unit 38 is not notified of the flooded elevator identification information. Specifically, when the inundation depth acquired periodically during a predetermined period is constant or decreased, the inundation depth does not increase thereafter, which hinders the operation of the elevator 10. Even if a predetermined period has elapsed, the horizontal position information extraction unit 38 is not notified of the acquired flooded elevator identification information. That is, in this case, the process for transmitting the save command is not performed. On the other hand, the inundated elevator identification information acquisition unit 34 assumes that if the inundation depth acquired periodically increases, the inundation depth is likely to increase thereafter, and after a predetermined period has elapsed. Then, the horizontal position information extraction unit 38 is notified of the acquired flooded elevator identification information. That is, in this case, processing for transmitting the save command is performed. Note that the predetermined period can be arbitrarily set.

  Furthermore, in the above description, the extraction unit 35 extracts the horizontal position extraction result under the horizontal position information extraction condition, and then extracts the elevator 10 to be saved under the vertical position information extraction condition.

Then, an evacuation command is transmitted to the evacuation target elevator 10. As a result, the elevator 10 that may be inundated by typhoon, river increase, tsunami, etc. is retracted before the actual inundation starts, but the elevator 10 that is not inundated is not retracted. That is, the elevator 10 that really needs to be evacuated can be commanded to evacuate. As a result, in the building elevator 10 that is arranged in a location where there is no risk of damage such as typhoons, river flooding, and tsunamis, unnecessary evacuation is not performed and the elevator 10 is operated.

As a result, it has an effect that it is possible to assist so as to quickly perform the recovery when the inundation occurs.

(Third embodiment)
In the first and second embodiments, an evacuation command is issued to an elevator having a predetermined horizontal positional relationship and a vertical positional relationship with respect to the elevator that has detected flooding. This assumes floods such as typhoons, river floods, and tsunamis that may occur in the area near the location of an elevator. However, flood damage includes local flood damage such as a rupture of a water pipe at a certain elevator installation position. In the third embodiment, an elevator control system that transmits an evacuation release command to an elevator that has transmitted an evacuation command when the inundation that caused the elevator to evacuate is a local flood will be described.

  FIG. 9 is a block diagram schematically illustrating an example of a functional configuration of the elevator control system according to the third embodiment. In the third embodiment, as shown in FIG. 9, the elevator control device 30 includes an evacuation target elevator identification information storage unit 45, a time determination unit 46, an evacuation release determination unit 47, and an evacuation release command transmission unit 48. And further comprising.

  The evacuation target elevator identification information storage unit 45 stores the evacuation target elevator identification information extracted by the extraction unit 35. For example, the extraction unit 35 can store the evacuation target elevator identification information in the evacuation target elevator identification information storage unit 45. The evacuation target elevator identification information storage unit 45 is a evacuation target storage unit that stores evacuation targets.

  The time determination unit 46 stores a determination reference time that is arbitrarily settable time information, and whether or not the determination reference time (first determination reference time) has elapsed since the save command transmission unit 42 transmitted the save command. Determine whether. In addition, when the determination reference time has elapsed, the time determination unit 46 transmits information indicating that the determination reference time has elapsed to the save release determination unit 47.

  When the retraction cancellation determination unit 47 acquires information indicating that the determination reference time has elapsed from the time determination unit 46, the retraction cancellation determination unit 47 determines whether or not the flooded elevator identification information has been acquired from any of the retreat target elevators within the determination reference time. The flooded elevator identification information acquisition unit 34 is inquired. The evacuation cancellation determination unit 47 can confirm that no inundation has occurred in all of the evacuation target elevators 10 within the determination reference time, that is, has not received inundation information from all the evacuation target elevators 10. In addition, since the inundation information that caused the save command is due to local flooding, a save release command transmission instruction for releasing the save status is passed to the save release command sending unit 48. In addition, the evacuation release determination unit 47 can confirm that the inundation has occurred in any of the evacuation target elevators within the determination reference time, that is, when the inundation information is received from any of the evacuation target elevators 10, Assuming that the inundation information that caused the evacuation command is not due to local flooding, nothing is done.

  When the evacuation cancellation command transmission unit 48 receives the instruction to transmit the evacuation cancellation command from the evacuation cancellation determination unit 47, the elevator 10 specified by the evacuation target elevator identification information in the evacuation target elevator identification information storage unit 45, that is, the evacuation target elevator. A save release command is transmitted to. The evacuation cancellation command transmission unit 48 transmits an evacuation cancellation command according to a predetermined communication standard with the elevator 10. In addition, the same code | symbol is attached | subjected to the component same as 1st and 2nd embodiment, and the description is abbreviate | omitted.

  FIG. 10 is a flowchart illustrating an example of a processing procedure of the save command transmission method in the elevator control device according to the third embodiment. Also in the third embodiment, the processes of steps S31 to S40 described in FIG. 5 of the first embodiment and the processes of steps S51 to S52 described in FIG. 8 of the second embodiment are performed. Next, after step S52, the extraction unit 35, in this example, the vertical position information extraction unit 41, stores the evacuation target elevator identification information in the evacuation target elevator identification information storage unit 45 (step S71).

  Thereafter, the time determination unit 46 determines whether or not the determination reference time (first determination reference time) has elapsed since the save command was transmitted in step S40 (step S72). If the determination reference time has not elapsed (No in step S72), the process waits until the determination reference time elapses. When the determination reference time has elapsed (Yes in step S72), the time determination unit 46 notifies the save cancellation determination unit 47 of information indicating that the determination reference time has elapsed. The evacuation cancellation determination unit 47 determines whether the inundation information has been received from any of the elevators 10 included in the evacuation target elevator identification information by making an inquiry to the inundation elevator identification information acquisition unit 34 (step S73).

  When the flood information is received from any elevator 10 included in the evacuation target elevator identification information (Yes in step S73), the process returns to step S31. This is because the inundation detected by the elevator 10 that is the transmission source of the inundation information received in step S33 spreads to other elevators 10 and is determined to be due to wide-area flood damage such as tsunami and typhoon. is there.

  On the other hand, when the inundation information has not been received from all the elevators 10 included in the evacuation target elevator identification information (No in step S73), the evacuation release determination unit 47 transmits the evacuation release command. The transmission unit 48 is instructed. When receiving the instruction, the evacuation cancellation command transmission unit 48 transmits an evacuation cancellation command to all the elevators 10 included in the evacuation target elevator identification information (step S74). This is because it is determined that the inundation detected by the elevator 10 that is the transmission source of the inundation information received in step S33 is due to local inundation such as a rupture of a water pipe in the building. Thereafter, the process returns to step S31.

  In the third embodiment, after the evacuation command is transmitted, the evacuation release command is transmitted when all the evacuation target elevators do not detect the inundation within the determination reference time. Accordingly, it is determined that the inundation in the elevator 10 that has transmitted the inundation detection information was inundation damage peculiar to the installation position of the elevator 10, and an unnecessary retreat state can be canceled.

(Fifth embodiment)
In the first to fourth embodiments, it is assumed that the elevator to be evacuated is in the evacuation state. However, there may be an elevator that cannot be moved to the retracted state for some reason, that is, an elevator that has not been retracted. Therefore, in the fifth embodiment, an elevator control system that notifies the manager of an incomplete evacuation elevator that the evacuation has not been completed when there is an incomplete evacuation elevator will be described.

  FIG. 14 is a block diagram schematically illustrating an example of a functional configuration of an elevator control system according to the fifth embodiment. In the fifth embodiment, as shown in FIG. 14, the elevator 10 further includes an evacuation completion detection unit 19.

  The evacuation completion detection unit 19 detects whether or not the elevator 10 is in a predetermined evacuation state when an evacuation command is output. Further, when the evacuation completion detection unit 19 is not in the evacuation state, the evacuation completion information indicating that the evacuation completion state is not in the evacuation state is transmitted to the elevator control device 30 in accordance with a predetermined communication standard. As a method for detecting whether or not the vehicle is in the evacuation state, there is a method in which the evacuation completion detection unit 19 obtains and confirms a signal for checking whether or not the vehicle is in the parking state by stopping at a predetermined reference floor. is there. This is an example, and other methods may be used. The incomplete saving information includes, for example, identification information acquired from the identification information storage unit 162 and information indicating that the saving is incomplete state.

  Further, in the fifth embodiment, as shown in FIG. 14, the elevator control device 30 includes an evacuation incomplete information reception unit 54, an evacuation incomplete elevator identification information acquisition unit 55, and an abnormal time contact determination unit 56.

Since it takes a predetermined time from when the elevator 10 receives the evacuation command until the evacuation process is completed, the evacuation determination reference time is set to a time longer than the predetermined time. Further, the retraction determination reference time may be the same as or different from the determination reference time of the third embodiment. In general, it is considered that the time required for determining that the water immersion in the third embodiment is local is longer than the time required for evacuation. Therefore, it is desirable that the retreat determination reference time is equal to or less than the determination reference time. If the evacuation judgment reference time has elapsed and the evacuation incomplete information has been received, the abnormal time communication determination unit 56 assumes that an event has occurred in the elevator 10 and the evacuation is not possible, and that the evacuation has not been completed. The completion elevator identification information is notified to the abnormal time communication unit 57.

  Upon receipt of a signal indicating an abnormal state from the abnormal time contact determination unit 56, the abnormal time communication unit 57 acquires a notification destination corresponding to the incomplete saved elevator identification information acquired from the contact information storage unit 43, The report destination is contacted according to a predetermined communication standard.

Also in the fifth embodiment, the same procedure as steps S31 to S71 described in the first to fourth embodiments is performed. Thereafter, the time determination unit 46 determines whether or not the save determination reference time has elapsed since the save command was output (step S101).

  If the save determination reference time has not elapsed since the save command was output (No in step S101), the process waits until the save determination reference time elapses. On the other hand, when the evacuation determination reference time has elapsed (in the case of Yes in step S101), the time determination unit 46 notifies the abnormality contact determination unit 56 of information indicating that the evacuation determination reference time has elapsed. The abnormal time contact determination unit 56 determines whether or not the evacuation incomplete information is received even after the evacuation determination reference time has elapsed (step S102). This is determined based on whether or not the save incomplete information receiving unit 54 has received the save incomplete information after the save determination reference time has elapsed.

  If the evacuation incomplete information is received even after the determination reference time has elapsed (Yes in step S102), the evacuation incomplete elevator identification information acquisition unit 55 acquires the evacuation incomplete elevator identification information ( Step S103), and hand it over to the abnormality contact determination unit 56. The abnormal-time communication determination unit 56 notifies the abnormal-time communication unit 57 of the acquired incomplete evacuation elevator identification information.

  Upon receiving the notification, the abnormal time communication unit 57 obtains a report destination corresponding to the incomplete evacuation identification information from the contact information (step S104), and the evacuation target elevator 10 is abnormal in the report destination. (Step S105). As a result, at the contact office, it is possible to dispatch a worker assuming that an abnormality has occurred in the elevator 10 that is not in the evacuated state even after the evacuation judgment reference time has elapsed since the evacuation command was output. become. Thereafter, or when the incomplete evacuation information has not been received after the evacuation determination reference time has elapsed in step S102 (No in step S102), the processes in steps S72 to S74 described in the third embodiment are performed. .

  In the above description, the case where the save completion detection unit 19 transmits the save incomplete information is described as an example, but the present embodiment is not limited to this. For example, the evacuation incomplete information may be transmitted to the elevator control device 30 via the control unit 16. In this case, the saving incomplete information may be received by the receiving unit 31 without providing the saving incomplete information receiving unit 54.

  In the fifth embodiment, when the elevator 10 that has been determined to be evacuated outputs a evacuation command and the evacuation determination reference time has not elapsed and the evacuation state has not elapsed, the predetermined contact address is contacted. Thereby, it is possible to promptly notify the contact person of the place to which the worker who performs the restoration work of the elevator 10 in the incomplete evacuation state belongs.
