  Hereinafter, embodiments of an elevator management device and an elevator management system will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a block diagram of an elevator management apparatus 100 and an elevator management system 200 according to this embodiment. The elevator management device 100 is a device that is in a range surrounded by a one-dot chain line in FIG. 1 and monitors the state of the elevator. The elevator management apparatus 100 is usually disposed in a monitoring center.

  The elevator has an elevator control device 1 that controls the elevator car. The elevator control device 1 is connected to an earthquake detector 2 and a communication device 3. The earthquake detector 2 is arranged in an elevator hoistway or in a machine room and transmits earthquake detection information to the elevator control device 1 when an earthquake is detected. The communication device 3 is connected to the elevator management apparatus 100 via the communication network 4. The communication device 3 transmits the earthquake detection information (elevator earthquake detection information 5) received by the elevator control device 1 from the earthquake detector 2 to the elevator management device 100 via the communication network 4. An example of the communication network 4 is a telephone line. However, the communication network 4 is not limited to a telephone line, and for example, wireless communication may be used.

  The elevator management apparatus 100 includes a storage unit 7, an elevator earthquake detection distribution map generation means 8, an earthquake intensity distribution map generation means 11, an approximation degree calculation means 13, a difference extraction means 14, an earthquake intensity comparison means 15, and a display. Part 16. The elevator earthquake detection distribution map generation means 8, the earthquake intensity distribution map generation means 11, the approximation degree calculation means 13, the difference extraction means 14, and the earthquake intensity comparison means 15 may be configured in a central processing unit (CPU) of a computer. Alternatively, each circuit may be configured by an individual circuit.

  The storage unit 7 stores elevator information 6. The elevator information 6 is information on the position where the earthquake detector 2 is installed (installation position information), information on the building where the earthquake sensor 2 is installed, and information on the type of the earthquake sensor 2 (earthquake detector information). Yes, it is information unique to the earthquake detector 2.

  Further, the storage unit 7 stores an earthquake detection distribution map (9B, 9C...) Created by an elevator earthquake detection distribution map generation means 8 described later and an earthquake intensity distribution map (12B) created by the earthquake intensity distribution map generation means 11. , 12C... Here, the storage unit 7 is a magnetic disk such as an HDD, a memory device, or the like. However, in the present embodiment and the following embodiments, the storage unit 7 is not limited to a magnetic disk or a memory device.

  The elevator earthquake detection distribution map generation means 8 generates an earthquake from the earthquake detection signal (elevator earthquake detection information 5) from the earthquake detector 2 installed in the elevator and the information specific to the earthquake detector 2 (elevator information 6). It is the circuit which creates the elevator earthquake detection distribution map 9A of the predetermined area | region in time.

  The earthquake intensity distribution map generation means 11 is a circuit that creates an earthquake intensity distribution map of a predetermined area at the time of occurrence of an earthquake based on the earthquake intensity information 10 of the earthquake in the predetermined area where the earthquake detector 2 is arranged. . The earthquake intensity information 10 is information on the intensity of earthquakes in various places issued from the outside of the elevator management apparatus 100 such as the Japan Meteorological Agency, for example, seismic intensity information.

  The degree-of-approximation calculating means 13 calculates the degree of approximation (degree of approximation) between the elevator earthquake detection distribution map 9A at the time of the earthquake occurrence and the past earthquake detection distribution maps (9B, 9C...) Accumulated in the storage unit 7. This is a circuit for selecting a past earthquake detection distribution map to be approximated.

  The difference extraction unit 14 is a circuit that extracts a difference between the elevator earthquake detection distribution map (9X) selected by the approximation degree calculation unit 13 and the elevator earthquake detection distribution map 9A when an earthquake occurs.

  For the difference extracted by the difference extraction means 14, the earthquake intensity comparison means 15 is a past earthquake intensity distribution map 12 (12X) corresponding to the earthquake intensity distribution map 12A at the time of the earthquake occurrence and the selected elevator earthquake detection distribution map 9X. And a circuit that compares

  The display unit 16 displays the extraction result based on the difference extraction unit 14 and the comparison result based on the earthquake intensity comparison unit 15.

  The failure determination means 17 determines whether or not the earthquake detector 2 has failed from the extraction result based on the difference extraction means 14 and the comparison result based on the earthquake intensity comparison means 15. The determination result may be displayed on the display unit 16.

  FIG. 2 is a control flowchart of the elevator management system 200 according to the first embodiment.

  The earthquake detector determines whether an earthquake has occurred (step S1). If it is determined that an earthquake has occurred (YES in step S1), the elevator management device 100 acquires the elevator earthquake detection information 5 (step S2), and the elevator An earthquake detection distribution map 9A is created (step S3).

  In parallel with the creation of the elevator earthquake detection distribution map 9A, the elevator management apparatus 100 of the present embodiment acquires the earthquake strength information 10 (step S4), and creates the earthquake strength distribution map 12A (step S5).

  The elevator management apparatus 100 according to the present embodiment creates an elevator earthquake detection distribution map 9A, and then uses the approximation calculation means 13 to store past elevator earthquake detection distribution maps 9 (9B, 9C,... ) And the currently created elevator earthquake detection distribution map 9A, and the degree of approximation is calculated (step S6).

  After calculating the degree of approximation, it is determined whether the degree of approximation is greater than or equal to a predetermined value set in advance (step S7). When the degree of approximation is not greater than or equal to a predetermined value, that is, when an earthquake similar to the current earthquake has not occurred in the past (NO in step S7), the elevator management apparatus 100 ends the flow. If the degree of approximation is greater than or equal to a predetermined value (YES in step S7), the difference extraction means 14 extracts the difference between the current elevator earthquake detection distribution map 9A and the past elevator earthquake detection distribution map 9 (9X). (Step S8).

  The earthquake intensity comparison means 15 compares the current earthquake intensity distribution map 12A and the past earthquake intensity distribution map 12 (12X) (step S9), and displays the difference on the display unit 16 (step S10). For example, when the difference is displayed in the past by the difference extraction unit 14 but there is an area where no earthquake is detected this time, the earthquake intensity is compared for the area.

  FIG. 3 is a comparison diagram between the present and the past regarding the elevator earthquake detection distribution and the earthquake intensity distribution according to the present embodiment. FIG. 3 (a1) is an elevator earthquake detection distribution map 9A of this time, and FIG. 3 (a2) is an elevator earthquake detection distribution map having a high degree of approximation in the past elevator earthquake detection distribution maps (9B, 9C...). 9X. 3 (a1) and 3 (a2) show the distribution of the detection of earthquakes detected by the earthquake detector 2 of each elevator divided into three levels of detection (no detection, low detection, high detection).

  The “no detection” area represents the earthquake detector 2 in which no earthquake was detected. The “low detection” area represents the earthquake detector 2 that has detected a low earthquake. The “high detection” area represents the earthquake detector 2 that has detected a high earthquake. These three levels are classified according to the gal value.

  The calculation of the degree of approximation between the elevator earthquake detection distribution map 9A and the elevator earthquake detection distribution map 9X (step S6 in FIG. 2) is, for example, the number of areas that differ for each detection level (no detection, low detection, high detection). Judge with. When the number of areas having a difference is small, it is determined that the approximate value is high. Further, for each detection level, when the comparison is made as a graphic and the difference is small, the approximate value may be large.

  FIG. 3 (b1) is the current seismic intensity distribution map 12A, and FIG. 3 (b2) is the seismic intensity distribution map 12X corresponding to the elevator earthquake detection distribution map 9X. The earthquake intensity distribution map 12X has a high degree of approximation in the past earthquake intensity distribution maps 12 (12B, 12C...).

  3 (b1) and (b2) are divided into three levels (less than Level 1.0, Level 1.0 or more and less than 3.0, Level 3.0 or more) regarding the seismic intensity detected by the seismic detector 2 of each elevator. The distribution is displayed. These three levels correspond to the seismic intensity. As an example, Level 1.0 is seismic intensity 1 and Level 3.0 is seismic intensity 3. However, the seismic intensity according to the level in this embodiment and the following embodiments is not limited to these numerical values.

  The difference extraction means 14 compares the region (a1) of this time that is detected by the earthquake earthquake detection distribution map 9A and (a2) the past elevator earthquake detection distribution map 9X having a high degree of approximation (the area enclosed by a broken line). Regions D1, D2, D3) are extracted.

  The seismic intensity comparison means 15 compares (b1) the current seismic intensity distribution map 12A and (b2) the past seismic intensity distribution map 12X for each of the regions D1, D2, and D3. An area is an area in which earthquake shaking was detected in the past, but this time the earthquake shaking is not detected ("no detection").

  In the failure determination by the failure determination means 17, the region D1 is located at the boundary between the region less than Level 1.0 and the region less than Level 1.0 and less than Level 3.0 from the seismic intensity distribution diagrams 12A and 12X. There is a possibility that the earthquake detector 2 of D1 is not detecting because there was no earthquake shake. That is, there is a low possibility that the seismic sensor 2 in the region D1 has failed.

  The region D2 is located in a region of Level 1.0 or more and less than Level 3.0 from the seismic intensity distribution diagrams 12A and 12X, and is not located at the boundary like the region D1. In this case, there is a possibility that the earthquake detector 2 in the region D2 has not detected the shaking of the earthquake due to the failure. However, when the seismic detector 2 is installed in a seismic or seismic isolation building, the gal value for detecting the seismic detection may be detected low. For this reason, there is a possibility that the earthquake detector 2 in the region D2 has not failed. That is, although the possibility that the seismic sensor 2 in the area D2 has failed is low, the possibility is higher than that in the area D1.

  The region D3 is located in a region of Level 3.0 or higher from the seismic intensity distribution diagrams 12A and 12X. In this case, there is a possibility that the seismic detector 2 in the region D3 does not detect the shaking of the earthquake due to the failure rather than the non-detection of the shaking due to the seismic detector 2 being installed in the earthquake-proof structure or the seismic isolation structure building. Is expensive. That is, the possibility that the seismic sensor 2 in the region D3 has failed is higher than that in the region D2.

  In the present embodiment, the elevator earthquake detection distribution maps 9A and 9X can be displayed on the display unit 16, and the seismic intensity distribution maps 12A and 12X can be displayed in comparison. Moreover, the dotted line of D1-D3 which is the difference of elevator earthquake detection distribution map 9A and 9X can be displayed. Note that the dotted line notation of D1 to D3 is not limited to FIG. 3, and the display method may be different depending on the possibility of failure of the earthquake detector 2. For example, D3 having a high possibility of failure of the seismic detector 2 may be darkened or colored, and D1 having a low possibility of failure may be omitted from the dotted line.

  Thereby, the elevator management apparatus of this embodiment can know the high or low possibility of the failure of the earthquake detector 2 by comparing the present and past of the elevator earthquake detection distribution map 9 and the earthquake intensity distribution map 12. Furthermore, maintenance inspection work can be performed preferentially from those with a high possibility of failure of the earthquake detector 2.

  In the present embodiment and the following embodiments, the display of the elevator earthquake detection distribution map 9 and the earthquake intensity distribution map 12 in three stages is an example, and the number of stages and the display method are not limited thereto.

  As described above, the elevator management apparatus according to the present embodiment can prevent a secondary disaster due to the failure of the earthquake sensor when an earthquake occurs.

(Second Embodiment)
The elevator management apparatus 101 of the second embodiment further includes a seismic control command output unit 18 that outputs a seismic control command to the elevator management apparatus 100 of the first embodiment. FIG. 4 is a block diagram of the elevator management apparatus 101 and the elevator management system 201 according to the present embodiment, and the earthquake control command output unit 18 is arranged to receive the result of the failure determination means 17.

  Based on the results of the approximation degree calculation means 13, the difference extraction means 14, and the earthquake intensity comparison means 15, the failure determination means 17 detects the level of the current earthquake detection for the areas (D1 to D3) of the elevator earthquake detection distribution maps 9A and 9X. (Elevator earthquake detection distribution map 9A) is assumed to be the same level as the level of past earthquake detection (elevator earthquake detection distribution map 9X).

  The seismic control command output unit 18 has detected an earthquake shake due to an earthquake similar to the past according to the level of the earthquake detection from the inference result of the failure determination means 17. This is a circuit that transmits a seismic control command to an elevator in an undetected area via the communication network 4.

  The seismic control command is a dedicated signal for controlling the elevator that detects the shaking by the earthquake detector 2. The earthquake control command output unit 18 transmits a signal for stopping the operation after moving the elevator to the nearest floor of the elevator that has detected low detection and evacuating the passenger from the passenger car. The seismic control command output unit 18 transmits a signal that causes the elevator that has detected high detection to urgently stop and does not perform operation up to the nearest floor. For example, a signal for stopping and driving to the nearest floor is transmitted to the area D2 in FIG. 3, and an emergency stop signal is transmitted to the area D3.

  FIG. 5 is a control flowchart of the elevator management system 201 according to the second embodiment. This embodiment further compares the current seismic intensity distribution map 12A with the past seismic intensity distribution map 12X (step S9) and displays the difference on the display unit 16 (step S10) from the first embodiment. Then, the failure of the earthquake detector 2 is determined, and the earthquake control command is output from the earthquake control command output unit 18 (step S21).

  Thereby, the elevator management apparatus of this embodiment can determine the seismic detector 2 by comparing the present and past of the elevator earthquake detection distribution map 9 and the earthquake intensity distribution map 12, and further issues an earthquake control command. It can be transmitted according to the level of past detection.

  As described above, the elevator management apparatus according to the present embodiment can prevent a secondary disaster due to the failure of the earthquake sensor when an earthquake occurs.

(Third embodiment)
The elevator management apparatus 102 of the third embodiment calculates the detection level from the surrounding area of the area (D1 to D3) for the earthquake detection level of the area (D1 to D3) to the elevator management apparatus 101 of the second embodiment. It has a function. The block diagram of the elevator management apparatus 102 and the elevator management system 202 of this embodiment is the same as that of FIG.

  FIG. 6 is a control flowchart of the elevator management system 202 according to the third embodiment. This embodiment further compares the current seismic intensity distribution map 12A with the past seismic intensity distribution map 12X (step S9) and displays the difference on the display unit 16 (step S10) from the second embodiment. Then, the earthquake detection rate in the vicinity of the detection level boundary is calculated, and it is determined whether or not it is a predetermined value or more (step S31). If it is equal to or greater than the predetermined value (YES in step S31), it is determined that the seismic detector 2 in the area is out of order, and an earthquake control command is output from the earthquake control command output unit 18 (step S21). If it is less than the predetermined value (NO in step S31), it is determined that the seismic detector 2 in the area has not failed and no seismic control command is output.

  FIG. 7 is a diagram of a method for calculating the earthquake detection rate in the elevator earthquake detection distribution according to the present embodiment. FIG. 7 (a1) is the current elevator earthquake detection distribution map 9A, and FIG. 7 (a2) is a high approximation in the past elevator earthquake detection distribution map 9X. The area D1 is “no detection” in the current elevator earthquake detection distribution, and “low detection” in the past elevator earthquake detection distribution map 9X. In the present embodiment, the determination of the failure of the earthquake detector 2 in the region D1 is made based on the region around the region D1 (the region surrounded by a dotted line).

  In the present embodiment, among the areas around D1, the “no detection” area is five areas, and the “low detection” area is three areas. The earthquake detection rate in the region D1 at this time is the ratio of the “low detection” region in the surrounding eight regions, that is, 3/8 (earthquake detection rate 37.5%).

  In FIG. 7, if the predetermined value is 4/8 (earthquake detection rate 50%), D1 is less than the predetermined value, and therefore the elevator management apparatus 102 of this embodiment does not have the failure of the D1 earthquake sensor. , D1 is determined as “no detection”. The predetermined value is 50% in this embodiment, but is not limited to this.

  In the present embodiment, in addition to the boundary between “no detection” and “low detection”, a failure may be similarly determined for the boundary between “low detection” and “high detection”. In this case, if there are many “high detections” in the surrounding area, the area is “high detection”, and if there are many “low detections”, the area is “low detection”.

  Thereby, the elevator management apparatus of this embodiment can determine the failure of the earthquake detector 2 by comparing the present and past of the elevator earthquake detection distribution map 9 and the seismic intensity distribution map 12, and further seismic control. The command can be transmitted according to the past detection level.

  As described above, the elevator management apparatus according to the present embodiment can prevent a secondary disaster due to the failure of the earthquake sensor when an earthquake occurs.

The elevator management device 103 of the fourth embodiment creates a distribution map including the tsunami information 20 in addition to the elevator management devices (100 to 102) of the first to third embodiments. FIG. 8 is a block diagram of the elevator management apparatus 103 and the elevator management system 203 of this embodiment. FIG. 8 associates the function of creating a distribution map including the tsunami information 20 with the third embodiment.

  The storage unit 7 stores a second seismic intensity distribution map 19 (19B, 19C...) Described later.

  The elevator management apparatus 103 creates a second seismic intensity distribution diagram 19A in which the tsunami information 20 is associated with the seismic intensity distribution diagram 12A (first seismic intensity distribution diagram) generated by the seismic intensity distribution diagram generating means 11.

  As the second earthquake distribution map, the earthquake information 20 may be added to the earthquake intensity distribution map 12A (first earthquake intensity distribution map) as a tsunami distribution map, or as a distribution map different from the earthquake strength distribution map 12A. You may create it. The tsunami information 20 is notification information (tsunami warning, tsunami warning) issued from the outside of the elevator management device 103 such as the Japan Meteorological Agency. In the case of past tsunami information 20, the tsunami generation and inundation are referred to as tsunami information 20.

  The seismic intensity comparing means 15 uses the second seismic intensity distribution in the past corresponding to the second seismic intensity distribution chart 19A and the selected elevator earthquake detection distribution chart at the time of the earthquake for the difference extracted by the difference extracting means 14. 19 is a circuit that compares FIG. 19 (19B, 19C...).

  The display unit 16 displays the extraction result based on the difference extraction unit 14 and the comparison result based on the earthquake intensity comparison unit 15. Further, the tsunami information 20 may be displayed.

  The tsunami evacuation command output unit 21 is a circuit that transmits a tsunami evacuation command to each elevator via the communication network 4 when a tsunami may occur.

  The tsunami evacuation order prevents inundation by evacuating the elevator car to the top floor of the elevator when a tsunami has occurred in the past or when notification information such as a tsunami warning or tsunami warning is issued. Signal.

  FIG. 9 is a control flowchart of the elevator management system 203 according to this embodiment. In the present embodiment, after the earthquake control command is output from the earthquake control command output unit 18 (step S21) from the third embodiment, the elevator management device 103 determines whether a tsunami has occurred in the past due to an earthquake ( Step S41). When a tsunami occurs at the time of the occurrence of the earthquake in the earthquake intensity distribution diagram 19 (hereinafter referred to as 19X) having a high degree of approximation (YES in step S41), the tsunami evacuation command output unit 21 is in the area where the tsunami has occurred in the past. Outputs a save command. In the earthquake intensity distribution diagram 19X, if no tsunami occurs (NO in step S41), the tsunami evacuation command is not output.

  FIG. 10 is a diagram of an earthquake intensity distribution diagram 19 in which the tsunami information 20 according to the present embodiment is associated. FIG. 10 (c1) is a second seismic intensity distribution diagram 19A in which tsunami information 20 (notification information) is added to the current seismic intensity distribution diagram 12A. FIG. 10C2 is a second seismic intensity distribution chart 19X in which the tsunami information 20 (past tsunami occurrence and inundation information) is associated with the seismic intensity distribution chart 12X. In the case of the tsunami information (c1), “0” indicates no notification information, and “1” indicates notification information (tsunami warning, tsunami warning). In the case of (c2), the tsunami information is “0” when there is no tsunami flooding in the past and “1” when there is flooding.

  In the present embodiment, in the second seismic intensity distribution map 19X of the earthquake that approximates the past, when inundation due to the tsunami has occurred, the area of the flooded area (area corresponding to “tsunami warning area,“ 1 ”)” All elevators receive earthquake evacuation orders. The earthquake evacuation operation is all performed without distinguishing the region (“high detection” and “low detection”) where the earthquake detector 2 detects shaking and the region (D3) where the earthquake detector 2 is not detecting.

  In this embodiment, even if no flooding has occurred in the past, if the notification information (tsunami warning or tsunami warning) is issued from the Japan Meteorological Agency, “0” in FIG. Even in this area, a tsunami evacuation command may be output to the area. In this case, the value is changed from “0” to “1”.

  8 to 10 described in detail the structure in which the tsunami evacuation command output unit 21 is provided in the third embodiment, the tsunami evacuation command output unit 21 is provided in the first embodiment and the second embodiment. May be.

  As described above, the elevator management apparatus according to the present embodiment can determine the failure of the earthquake detector and further prevent damage (flooding, flooding) due to the tsunami.

(Fifth embodiment)
FIG. 11 is a block diagram of an elevator management apparatus 104 and an elevator management system 204 according to the fifth embodiment. The elevator management apparatus 104 of this embodiment further receives the tsunami arrival prediction information 22 from the fourth embodiment. The tsunami arrival prediction information 22 is a prediction of the arrival time until the tsunami reaches the tsunami warning area (the area “1” in FIG. 10). For example, information indicating that a tsunami will arrive in another 10 minutes.

  When the elevator management apparatus 104 according to the present embodiment receives an tsunami arrival prediction information 22 when an earthquake occurs and the tsunami arrival prediction information 22 is within a predetermined time, a tsunami evacuation command is issued to the tsunami warning area. Is output. For example, when the tsunami arrival prediction time is 10 minutes and the predetermined time is 6 minutes, 4 minutes after receiving the tsunami arrival prediction information 22, that is, when the remaining time is 6 minutes or less In addition, a tsunami evacuation command is output. The tsunami arrival prediction information 22 is received from the Japan Meteorological Agency or the like. If the tsunami arrival prediction information 22 is updated, it may be output each time.

  FIG. 12 is a flowchart of control of the elevator management system 204 according to the present embodiment. In the present embodiment, it is determined whether a tsunami has occurred in the past. If a tsunami has occurred (YES in step S41), it is determined whether a predetermined time has been reached until the tsunami arrival time (step S51). If it is not within the predetermined time (NO in step S51), the elevator car is put on standby until the predetermined time is reached, and the user is blamed. If it is within the predetermined time (YES in step S51), the tsunami evacuation command output unit 21 outputs a tsunami evacuation command to the elevator in the tsunami warning area, and moves the car to the top floor. This prevents flooding and flooding of the car.

  The elevator management device 104 may output the tsunami arrival prediction information 22 together with the tsunami evacuation command to the elevator in the tsunami warning area. As a result, it is possible to notify the user of the predicted time until the arrival of the tsunami and to prompt evacuation.

  As described above, the elevator management apparatus according to the present embodiment can determine the failure of the earthquake detector and further prevent damage (flooding, flooding) due to the tsunami. Furthermore, it becomes possible to prompt the user of the elevator to evacuate.
