Detailed Description
The invention is described with reference to the accompanying drawings. The duplicate description will be appropriately simplified or omitted. Like reference symbols in the various drawings indicate like or corresponding parts.
Embodiment mode 1
Fig. 1 is a diagram showing a configuration example of a restoration support system according to embodiment 1 of the present invention. The recovery support system includes an elevator device 1, a monitoring device 2, an entrance/exit management system 3, and a recovery system 4.
Fig. 1 shows an example in which 4 elevator apparatuses 1 are installed in the same building 5. The number of elevator apparatuses 1 installed in the building 5 may be 3 or less, or 5 or more. For example, only 1 elevator apparatus 1 may be installed in the building 5.
The elevator apparatus 1 has an automatic recovery function. In the example shown in fig. 1, all of the elevator apparatuses 1 provided in the building 5 have an automatic return function. Only a part of the elevator apparatus 1 provided in the building 5 may have an automatic return function. The automatic recovery function is a function that can be automatically recovered without the intervention of maintenance personnel after an earthquake occurs. For example, a seismic detector 6 is provided in the building 5. When the earthquake detector 6 detects an earthquake of a certain level or more, the elevator apparatus 1 starts the earthquake-time control operation. The controlled operation during an earthquake is an operation for allowing a user to get off the car. In the controlled operation during earthquake, the car stops at the nearest floor. When the car stops at the nearest floor, the door opens. When a predetermined time has elapsed since the door was opened, the door is closed. This completes the control operation in the earthquake and stops the elevator apparatus 1.
The elevator apparatus 1 starts the spot check operation when a predetermined time has elapsed from the end of the earthquake time control operation. The spot inspection operation is an operation for determining whether or not automatic recovery is possible. For example, various data are acquired in the spot check operation. The acquired data is compared with a reference value or a reference range for the data. And judging whether the automatic recovery can be realized according to the comparison result.
In addition, if the car stops at the landing and no passenger rides on the car when an earthquake occurs, the elevator apparatus 1 may start the spot check operation without performing the controlled operation during the earthquake.
The elevator apparatus 1 determines that recovery is possible if a specific abnormality is not detected during the spot inspection operation. If the elevator apparatus 1 can be recovered, a signal indicating that recovery is possible is transmitted to the monitoring apparatus 2. Thereby, the elevator apparatus 1 is restored to resume the normal operation. The normal operation is an operation in which a car responds to a registered call.
When a specific abnormality is detected during the spot detection operation, the elevator apparatus 1 determines that recovery is not possible. If the elevator apparatus 1 cannot be recovered, a signal indicating that recovery is not possible is transmitted to the monitoring apparatus 2. This stops the spot inspection operation, and the elevator apparatus 1 is stopped again.
The entrance/exit management system 3 manages entrance/exit to/from the building 5. The access management system 3 includes, for example, an identification tag held by a person and a reader for reading information of the identification tag. The reader is provided on, for example, a wall adjacent to the doorway of the building 5. The entry and exit management system 3 stores information indicating the position (location) of the holder of the identification tag. The information is periodically updated based on the information read by the reader. Therefore, information on the person currently located in the building 5 is stored in the access management system 3.
The entrance/exit management system 3 may manage rooms, floors, and the like in the entrance/exit building 5. In this case, information on the person currently located in each room of the building 5 or information on the person currently located on each floor is stored in the entrance and exit management system 3.
The maintenance company 7 is responsible for maintenance of the elevator apparatus 1 installed in the building 5. In the present embodiment, an example is shown in which the maintenance company 7 takes charge of maintenance of all the elevator apparatuses 1 installed in the building 5. A plurality of maintenance personnel are affiliated with the maintenance company 7. The maintenance person is a professional technician in connection with the elevator. The maintenance of the elevator installation 1 is carried out by maintenance personnel who are affiliated with the maintenance company 7. The maintenance company 7 can perform bidirectional communication with the monitoring apparatus 2.
The monitoring device 2 monitors the elevator device 1 provided in the building 5. The monitoring device 2 is installed in, for example, a building 5. The monitoring device 2 includes, for example, a recovery signal receiving unit 8, a person number calculating unit 9, a person number information acquiring unit 10, a time calculating unit 11, a transmitting unit 12, a dispatch plan receiving unit 13, a time calculating unit 14, and a notifying unit 15.
The recovery signal receiving unit 8 receives information from the elevator apparatus 1. The recoverable signal and the non-recoverable signal transmitted from the elevator apparatus 1 are received by the recoverable signal receiving unit 8. Further, the plurality of elevator apparatuses 1 installed in the building 5 may be group-controlled by a group control device. In this case, the recovery signal receiving unit 8 may receive a recovery-enabled signal and a recovery-disabled signal from the group control device.
The number-of-persons calculation unit 9 calculates the number of persons that can be evacuated by the elevator apparatus 1 per unit time. For example, the person count calculation unit 9 performs the above calculation based on the signal received by the recovery signal reception unit 8 after the occurrence of an earthquake.
The person number information acquiring unit 10 acquires information on the number of persons remaining in the building 5. For example, the person number information acquiring unit 10 acquires the information from the entrance and exit management system 3 after an earthquake occurs.
The time calculation unit 11 calculates the time taken until the person left in the building 5 refuges. For example, the time calculation unit 11 calculates the time based on the number of people calculated by the number of people calculation unit 9 and the information acquired by the number of people information acquisition unit 10.
The transmission unit 12 transmits information to the maintenance company 7. In the example shown in the present embodiment, the maintenance company 7 has the recovery system 4. For example, the transmission unit 12 transmits the information of the time calculated by the time calculation unit 11 to the recovery system 4.
The recovery system 4 includes, for example, a dispatch plan generating unit 16. The dispatch plan generator 16 generates a dispatch plan of a maintenance worker who belongs to the maintenance company 7. For example, the dispatch plan generator 16 generates a dispatch plan based on the time information transmitted from the transmitter 12. In the dispatch plan, the sequence of buildings to be traveled to for the restoration of the elevator apparatus is registered for each maintenance person. The dispatch plan generated by the dispatch plan generating unit 16 is transmitted to the monitoring apparatus 2.
The dispatch plan receiving unit 13 receives information from the maintenance company 7. In the example shown in the present embodiment, the dispatch plan receiving unit 13 receives a dispatch plan from the recovery system 4.
The time calculation unit 14 calculates the time taken until all the elevator apparatuses 1 installed in the building 5 are recovered. The time calculation unit 14 calculates the time based on the dispatch plan received by the dispatch plan reception unit 13.
The notification unit 15 notifies the information on the elevator from the notifier 17. The notification device 17 is provided in the elevator apparatus 1, for example. For example, the notification device 17 is constituted by a display or a broadcast device provided in the hall or the like. The notification device 17 may not be provided in the elevator apparatus 1. For example, the notifier 17 may be a portable terminal held by the holder of the identification tag. The notification unit 15 causes the time calculated by the time calculation unit 14 to be notified from the notifier 17.
Next, the operation of the recovery support system will be described in detail with reference to fig. 2 to 4. Fig. 2 is a flowchart showing the operation of the elevator apparatus 1.
The elevator apparatus 1 determines whether or not an earthquake has occurred (S101). If no earthquake occurs, the elevator apparatus 1 performs normal operation. When an earthquake is detected by the earthquake detector 6 while the normal operation is being performed, the car stops (S102). For example, when an earthquake occurs while the car is moving, the earthquake-time regulation operation is started. The cage stops at the nearest floor by controlling operation during earthquake.
When a predetermined time has elapsed since the completion of the earthquake time control operation in the elevator apparatus 1, the point inspection operation is started (S103). Various data are acquired in the spot inspection operation. The acquired data is compared to a reference value or range for the data. Whether or not the automatic recovery is possible is determined based on the result of the comparison (S104).
If no specific abnormality is detected during the spot check operation, the elevator apparatus 1 determines that recovery is possible (S104: YES). If the elevator apparatus 1 can be recovered, a signal indicating that recovery is possible is transmitted to the monitoring apparatus 2 (S105). Then, the elevator apparatus 1 automatically returns to start the normal operation again (S106).
When a specific abnormality is detected during the spot detection operation, the elevator apparatus 1 determines that recovery is not possible (S104: NO). If the elevator apparatus 1 cannot be recovered, a signal indicating that recovery cannot be performed is transmitted to the monitoring apparatus 2 (S107). The elevator apparatus 1 is stopped and placed in a standby state until the maintenance worker manually returns (S108).
Fig. 3 is a flowchart showing the operation of the monitoring apparatus 2. The monitoring apparatus 2 determines whether or not a recoverable signal or a non-recoverable signal has been received (S201). When an earthquake occurs, a recoverable signal or a non-recoverable signal is transmitted from the elevator apparatus 1. In the monitoring device 2, the recovery signal receiving unit 8 receives the recoverable signal and the unrecoverable signal (S201: yes).
When the recovery signal receiving unit 8 receives the recovery enabled signal or the recovery disabled signal from all the elevator apparatuses 1 installed in the building 5, the number-of-persons calculating unit 9 calculates the number of persons that can be evacuated by the elevator apparatuses 1 in the building 5 per unit time (S202). For example, the number-of-persons calculation unit 9 calculates the number of persons that can be evacuated per unit time by the automatically-recoverable elevator apparatus 1 of the elevator apparatuses 1 installed in the building 5. When the restoration signal receiving unit 8 receives the restoration enabling signal or the restoration disabling signal from all the elevator apparatuses 1 having the automatic restoration function, the person number calculating unit 9 may perform the processing of S202 and the processing of S203 described below.
For example, consider an example in which the rated number of cars in the elevator apparatus 1 is 8, and the cars travel back and forth between the lowermost floor and the uppermost floor of the building 5 in 5 minutes. It is assumed that a recoverable signal is received from 2 elevator apparatuses 1 out of 4 elevator apparatuses 1 and a non-recoverable signal is received from 2 elevator apparatuses 1. In this case, the person number calculating unit 9 obtains a calculation result of 3.2 (person/minute) according to the following equation.
8 (man) × 2 (table)/5 (min) ═ 3.2 (man/min) … … (1)
When the normal operation is resumed in S106 of fig. 2, the spot check by the maintenance person is not performed. Therefore, the normal operation can be performed by reducing the car speed before the spot inspection by the maintenance person. In this case, the number-of-persons calculating unit 9 may calculate the number of persons per unit time by multiplying the result obtained by equation (1) by a coefficient, for example. The following equation is an example in which the coefficient is set to 0.5. In addition, the value of the coefficient is not limited to 0.5.
8 (man) × 2 (table)/5 (min) × 0.5.5 ═ 1.6 (man/min) … … (2)
When the restoration signal receiving unit 8 receives the restoration enabling signal or the restoration disabling signal from all the elevator apparatuses 1 installed in the building 5, the person number information acquiring unit 10 acquires the person number information remaining in the building 5 (S203). For example, the information acquiring unit 10 acquires the information from the entrance/exit management system 3. For example, the person number information acquiring unit 10 acquires the person number information of all the persons remaining in the building 5.
Further, it is conceivable that a person who is located at a floor below a certain floor is evacuated using a staircase or the like without using the elevator apparatus 1. When the entrance/exit management system 3 manages the rooms entering and exiting the building 5, the people number information acquiring unit 10 may acquire the information on the number of people who remain in the building 5. For example, the number-of-persons information acquiring unit 10 may acquire the number of persons remaining on a floor of 5 or more floors of the building 5.
Next, the time calculation unit 11 calculates the time taken until the person left in the building 5 refuges (S204). The time calculation unit 11 calculates the time based on the number of people calculated in S202 and the information on the number of people acquired in S203. For example, consider a case where the number of people per unit time calculated by the number-of-people calculation unit 9 is 1.6 (people/minute), and the number-of-people information acquisition unit 10 acquires 100 pieces of information that are left in the building 5. In this case, the time calculation unit 11 obtains a calculation result of 62.5 minutes according to the following equation.
100 (person)/1.6 (person/min) ═ 62.5 (min)
The transmission unit 12 transmits the information of the time calculated by the time calculation unit 11 to the maintenance company 7 (S205). The transmission unit 12 may transmit the information of the time calculated by the time calculation unit 11 to the maintenance company 7 together with other information. For example, the transmission unit 12 may transmit information of the elevator apparatus 1 determined to be unrecoverable, information of an abnormality detected during the spot check operation, and information of the number of people remaining in the building 5 to the maintenance company 7.
Fig. 4 is a flowchart showing the operation of the recovery system 4. In the recovery system 4, it is determined whether or not the information of the time calculated by the time calculation unit 11 is received from the monitoring device 2 (S301). The maintenance company 7 is responsible for maintenance of not only the elevator apparatus 1 installed in the building 5 but also elevator apparatuses installed in other buildings. Therefore, even when an earthquake occurs, the recovery system 4 receives information of the time taken until evacuation is completed from the monitoring apparatus installed in another building.
The dispatch plan generator 16 generates a dispatch plan for the maintenance person based on the information received from the plurality of monitoring devices (S302). The information of the dispatch plan generated by the dispatch plan generating unit 16 is transmitted from the recovery system 4 to the monitoring apparatus 2 (S303).
After the information is transmitted in S205, the monitoring apparatus 2 determines whether or not the dispatch plan information is received from the recovery system 4 (S206). When the dispatch plan receiving unit 13 receives the dispatch plan information, the time calculating unit 14 calculates the time taken until all the elevator apparatuses 1 installed in the building 5 are recovered (S207). The notification unit 15 causes the notifier 17 to notify the information of the time calculated by the time calculation unit 14 (S208).
In the example shown in the present embodiment, the time taken until the person remaining in the building 5 refuges by the elevator apparatus 1 is calculated, and information of the calculated time is transmitted to the maintenance company 7. Therefore, the maintenance company 7 can generate the dispatch plan in consideration of the evacuation condition in the building 5 as well. The maintenance worker can efficiently perform the restoration work of the elevator apparatus 1 installed in the building 5 and the elevator apparatuses installed in other buildings.
In the example shown in the present embodiment, the time until recovery is calculated from the dispatch plan received from the maintenance company 7, and the information of the calculated time is notified from the notifier 17. Thus, the person located in the building 5 can know when the elevator apparatus 1 is restored. Further, a person who cannot evacuate without using the elevator apparatus 1 can know when evacuation is possible. The mental burden on the person located in the building 5 can be reduced.
In the example shown in the present embodiment, an example in which a plurality of elevator apparatuses 1 are provided in a building 5 is described in detail. As described above, only 1 elevator apparatus 1 may be installed in the building 5. In this case, if the elevator apparatus 1 can automatically return, the number-of-persons calculation unit 9 calculates the number of persons that can be evacuated by the elevator apparatus 1 per unit time.
The parts shown by reference numerals 8 to 15 indicate functions which the monitoring apparatus 2 has. Fig. 5 is a diagram showing a hardware configuration of the monitoring apparatus 2. The monitoring apparatus 2 has, as hardware resources, processing circuitry including, for example, a processor 18 and a memory 19. The monitoring apparatus 2 realizes various functions by the processor 18 executing a program stored in the memory 19.
The processor 18 is also called a CPU (Central Processing Unit), a Central Processing Unit, a Processing device, an arithmetic device, a microprocessor, a microcomputer, or a DSP. The memory 19 may be a semiconductor memory, a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, or a DVD. Semiconductor memories that can be used include RAM, ROM, flash memory, EPROM, EEPROM, and the like.
A part or all of the functions of the monitoring apparatus 2 may be realized by hardware. As hardware for realizing the functions of the monitoring apparatus 2, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof may be used.
The dispatch plan generator 16 shows the function of the recovery system 4. The hardware configuration of the recovery system 4 is the same as the example shown in fig. 5. The recovery system 4 has, as hardware resources, processing circuits including, for example, a processor and a memory. The recovery system 4 realizes the above-described functions by executing a program stored in a memory by a processor.
